    Build derivations in a more predictable order

    Derivations are now built in order of derivation name, so a package
    named "aardvark" is built before "baboon".

    Disable vacuuming the DB after garbage collection

    Especially in WAL mode on a highly loaded machine, this is not a good
    idea because it results in a WAL file of approximately the same size
    ad the database, which apparently cannot be deleted while anybody is
    accessing it.

    nix-daemon: Call exit(), not _exit()

    This was preventing destructors from running. In particular, it was
    preventing the deletion of the temproot file for each worker
    process. It may also have been responsible for the excessive WAL
    growth on Hydra (due to the SQLite database not being closed
    properly).

    Apparently broken by accident in

    Allow regular files as GC roots

    If a root is a regular file, then its name must denote a store
    path. For instance, the existence of the file

      /nix/var/nix/gcroots/per-user/eelco/hydra-roots/wzc3cy1wwwd6d0dgxpa77ijr1yp50s6v-libxml2-2.7.7

    would cause

      /nix/store/wzc3cy1wwwd6d0dgxpa77ijr1yp50s6v-libxml2-2.7.7

    to be a root.

    This is useful because it involves less I/O (no need for a readlink()
    call) and takes up less disk space (the symlink target typically takes
    up a full disk block, while directory entries are packed more
    efficiently). This is particularly important for hydra.nixos.org,
    which has hundreds of thousands of roots, and where reading the roots
    can take 25 minutes.

    nix-daemon: Add trusted-users and allowed-users options

    ‘trusted-users’ is a list of users and groups that have elevated

    ‘allowed-users’ is a list of users and groups that are allowed to
    connect to the daemon. It defaults to ‘*’. A typical value would be
    ‘@users’ to specify the ‘users’ group.

    Handle case collisions on case-insensitive systems

    When running NixOps under Mac OS X, we need to be able to import store
    paths built on Linux into the local Nix store. However, HFS+ is
    usually case-insensitive, so if there are directories with file names
    that differ only in case, then importing will fail.

    The solution is to add a suffix ("~nix~case~hack~<integer>") to
    colliding files. For instance, if we have a directory containing
    xt_CONNMARK.h and xt_connmark.h, then the latter will be renamed to
    "xt_connmark.h~nix~case~hack~1". If a store path is dumped as a NAR,
    the suffixes are removed. Thus, importing and exporting via a
    case-insensitive Nix store is round-tripping. So when NixOps calls
    nix-copy-closure to copy the path to a Linux machine, you get the
    original file names back.

    Closes #119.

    build-remote.pl: Use ‘nix-store --serve’ on the remote side

    This makes things more efficient (we don't need to use an SSH master
    connection, and we only start a single remote process) and gets rid of
    locking issues (the remote nix-store process will keep inputs and
    outputs locked as long as they're needed).

    It also makes it more or less secure to connect directly to the root
    account on the build machine, using a forced command
    (e.g. ‘command="nix-store --serve --write"’). This bypasses the Nix
    daemon and is therefore more efficient.

    Also, don't call nix-store to import the output paths.

    nix-copy-closure: Fix race condition

    There is a long-standing race condition when copying a closure to a
    remote machine, particularly affecting build-remote.pl: the client
    first asks the remote machine which paths it already has, then copies
    over the missing paths. If the garbage collector kicks in on the
    remote machine between the first and second step, the already-present
    paths may be deleted. The missing paths may then refer to deleted
    paths, causing nix-copy-closure to fail. The client now performs both
    steps using a single remote Nix call (using ‘nix-store --serve’),
    locking all paths in the closure while querying.

    I changed the --serve protocol a bit (getting rid of QueryCommand), so
    this breaks the SSH substituter from older versions. But it was marked
    experimental anyway.

    Fixes #141.

    Add importNative primop

    This can be used to import a dynamic shared object and return an
    arbitrary value, including new primops. This can be used both to test
    new primops without having to recompile nix every time, and to build
    specialized primops that probably don't belong upstream (e.g. a function
    that calls out to gpg to decrypt a nixops secret as-needed).

    The imported function should initialize the Value & as needed. A single
    import can define multiple values by creating an attrset or list, of
    course.

    An example initialization function might look like:

    extern "C" void initialize(nix::EvalState & state, nix::Value & v)
    {
        v.type = nix::tPrimOp;
        v.primOp = NEW nix::PrimOp(myFun, 1, state.symbols.create("myFun"));
    }

    Then `builtins.importNative ./example.so "initialize"` will evaluate to
    the primop defined in the myFun function.

    Make the Nix search path declarative

    Nix search path lookups like <nixpkgs> are now desugared to ‘findFile
    nixPath <nixpkgs>’, where ‘findFile’ is a new primop. Thus you can
    override the search path simply by saying

      let
        nixPath = [ { prefix = "nixpkgs"; path = "/my-nixpkgs"; } ];
      in ... <nixpkgs> ...

    In conjunction with ‘scopedImport’ (commit
    c273c15cb13bb86420dda1e5341a4e19517532b5), the Nix search path can be
    propagated across imports, e.g.

      let

        overrides = {
          nixPath = [ ... ] ++ builtins.nixPath;
          import = fn: scopedImport overrides fn;
          scopedImport = attrs: fn: scopedImport (overrides // attrs) fn;
          builtins = builtins // overrides;
        };

      in scopedImport overrides ./nixos

    Add constant ‘nixPath’

    It contains the Nix expression search path as a list of { prefix, path
    } sets, e.g.

      [ { path = "/nix/var/nix/profiles/per-user/root/channels/nixos"; prefix = ""; }
        { path = "/etc/nixos/configuration.nix"; prefix = "nixos-config"; }
        { path = "/home/eelco/Dev/nix/inst/share/nix/corepkgs"; prefix = "nix"; }
      ]

    Add primop ‘scopedImport’

    ‘scopedImport’ works like ‘import’, except that it takes a set of
    attributes to be added to the lexical scope of the expression,
    essentially extending or overriding the builtin variables.  For
    instance, the expression

      scopedImport { x = 1; } ./foo.nix

    where foo.nix contains ‘x’, will evaluate to 1.

    This has a few applications:

    * It allows getting rid of function argument specifications in package
      expressions. For instance, a package expression like:

        { stdenv, fetchurl, libfoo }:

        stdenv.mkDerivation { ... buildInputs = [ libfoo ]; }

      can now we written as just

        stdenv.mkDerivation { ... buildInputs = [ libfoo ]; }

      and imported in all-packages.nix as:

        bar = scopedImport pkgs ./bar.nix;

      So whereas we once had dependencies listed in three places
      (buildInputs, the function, and the call site), they now only need
      to appear in one place.

    * It allows overriding builtin functions. For instance, to trace all
      calls to ‘map’:

      let
        overrides = {
          map = f: xs: builtins.trace "map called!" (map f xs);

          # Ensure that our override gets propagated by calls to
          # import/scopedImport.
          import = fn: scopedImport overrides fn;

          scopedImport = attrs: fn: scopedImport (overrides // attrs) fn;

          # Also update ‘builtins’.
          builtins = builtins // overrides;
        };
      in scopedImport overrides ./bla.nix

    * Similarly, it allows extending the set of builtin functions. For
      instance, during Nixpkgs/NixOS evaluation, the Nixpkgs library
      functions could be added to the default scope.

    There is a downside: calls to scopedImport are not memoized, unlike
    import. So importing a file multiple times leads to multiple parsings
    / evaluations. It would be possible to construct the AST only once,
    but that would require careful handling of variables/environments.

    nix-store -l: Fetch build logs from the Internet

    If a build log is not available locally, then ‘nix-store -l’ will now
    try to download it from the servers listed in the ‘log-servers’ option
    in nix.conf. For instance, if you have:

      log-servers = http://hydra.nixos.org/log

    then it will try to get logs from http://hydra.nixos.org/log/<base
    name of the store path>. So you can do things like:

      $ nix-store -l $(which xterm)

    and get a log even if xterm wasn't built locally.

    Preload linked hashes to speed up lookups

    By preloading all inodes in the /nix/store/.links directory, we can
    quickly determine of a hardlinked file was already linked to the hashed
    links.
    This is tolerant of removing the .links directory, it will simply
    recalculate all hashes in the store.

    Shortcut already-hardlinked files

    If an inode in the Nix store has more than 1 link, it probably means that it was linked into .links/ by us. If so, skip.

    There's a possibility that something else hardlinked the file, so it would be nice to be able to override this.

    Also, by looking at the number of hardlinks for each of the files in .links/, you can get deduplication numbers and space savings.

    nix-env: Minor change to '--delete-generations Nd' semantics

    The option '--delete-generations Nd' deletes all generations older than N
    days. However, most likely the user does not want to delete the
    generation that was active N days ago.

    For example, say that you have these 3 generations:

    1: <30 days ago>
    2: <15 days ago>
    3: <1 hour ago>

    If you do --delete-generations 7d (say, as part of a cron job), most
    likely you still want to keep generation 2, i.e. the generation that was
    active 7 days ago (and for most of the past 7 days, in fact).

    This patch fixes this issue. Note that this also affects
    'nix-collect-garbage --delete-older-than Nd'.

    Thanks to @roconnor for noticing the issue!

    Make sure /dev/pts/ptmx is world-writable

    While running Python 3’s test suite, we noticed that on some systems
    /dev/pts/ptmx is created with permissions 0 (that’s the case with my
    Nixpkgs-originating 3.0.43 kernel, but someone with a Debian-originating
    3.10-3 reported not having this problem.)

    There’s still the problem that people without
    CONFIG_DEVPTS_MULTIPLE_INSTANCES=y are screwed (as noted in build.cc),
    but I don’t see how we could work around it.

    Fix potential segfault in waitForInput()

    Since the addition of build-max-log-size, a call to
    handleChildOutput() can result in cancellation of a goal.  This
    invalidated the "j" iterator in the waitForInput() loop, even though
    it was still used afterwards.  Likewise for the maxSilentTime
    handling.

    Probably fixes #231.  At least it gets rid of the valgrind warnings.

    Don't interpret strings as format strings

    Ludo reported this error:

      unexpected Nix daemon error: boost::too_few_args: format-string refered to more arguments than were passed

    coming from this line:

      printMsg(lvlError, run.program + ": " + string(err, 0, p));

    The problem here is that the string ends up implicitly converted to a
    Boost format() object, so % characters are treated specially.  I
    always assumed (wrongly) that strings are converted to a format object
    that outputs the string as-is.

    Since this assumption appears in several places that may be hard to
    grep for, I've added some C++ type hackery to ensures that the right
    thing happens.  So you don't have to worry about % in statements like

      printMsg(lvlError, "foo: " + s);

    or

      throw Error("foo: " + s);

    Make /dev/kvm optional

    The daemon now creates /dev deterministically (thanks!).  However, it
    expects /dev/kvm to be present.

    The patch below restricts that requirement (1) to Linux-based systems,
    and (2) to systems where /dev/kvm already exists.

    I’m not sure about the way to handle (2).  We could special-case
    /dev/kvm and create it (instead of bind-mounting it) in the chroot, so
    it’s always available; however, it wouldn’t help much since most likely,
    if /dev/kvm missing, then KVM support is missing.

    Allow recovery from isValidPath RPCs with an invalid path

    Currently, clients cannot recover from an isValidPath RPC with an
    invalid path parameter because the daemon closes the connection when
    that happens.

    More precisely:

      1. in performOp, wopIsValidPath case, ‘readStorePath’ raises an
         ‘Error’ exception;

      2. that exception is caught by the handler in ‘processConnection’;

      3. the handler determines errorAllowed == false, and thus exits after
         sending the message.

    This last part is fixed by calling ‘startWork’ early on, as in the patch
    below.

    The same reasoning could be applied to all the RPCs that take one or
    more store paths as inputs, but isValidPath is, by definition, likely to
    be passed invalid paths in the first place, so it’s important for this
    one to allow recovery.

    Correctly detect infinite recursion in function application

    If we're evaluating some application ‘v = f x’, we can't store ‘f’
    temporarily in ‘v’, because if ‘f x’ refers to ‘v’, it will get ‘f’
    rather than an infinite recursion error.

    Unfortunately, this breaks the tail call optimisation introduced in
    c897bac54954373f63511702731fe2cb23c0c98e.

    Fixes #217.

    We were relying on SubstitutionGoal's destructor releasing the lock,

    release it explicitly.

    This allows you to easily set up a build environment containing the

      $ nix-shell -p sqlite xorg.libX11 hello

    will start a shell in which the given packages are present.

    Add a flag ‘--check’ to verify build determinism

    The flag ‘--check’ to ‘nix-store -r’ or ‘nix-build’ will cause Nix to
    redo the build of a derivation whose output paths are already valid.
    If the new output differs from the original output, an error is
    printed.  This makes it easier to test if a build is deterministic.
    (Obviously this cannot catch all sources of non-determinism, but it
    catches the most common one, namely the current time.)

    For example:

      $ nix-build '<nixpkgs>' -A patchelf
      ...
      $ nix-build '<nixpkgs>' -A patchelf --check
      error: derivation `/nix/store/1ipvxsdnbhl1rw6siz6x92s7sc8nwkkb-patchelf-0.6' may not be deterministic: hash mismatch in output `/nix/store/4pc1dmw5xkwmc6q3gdc9i5nbjl4dkjpp-patchelf-0.6.drv'

    The --check build fails if not all outputs are valid.  Thus the first
    call to nix-build is necessary to ensure that all outputs are valid.

    The current outputs are left untouched: the new outputs are either put
    in a chroot or diverted to a different location in the store using
    hash rewriting.

    Add download-via-ssh substituter

    This substituter connects to a remote host, runs nix-store --serve
    there, and then forwards substituter commands on to the remote host and
    sends their results to the calling program. The ssh-substituter-hosts
    option can be specified as a list of hosts to try.

    This is an initial implementation and, while it works, it has some
    limitations:

    * Only the first host is used
    * There is no caching of query results (all queries are sent to the
      remote machine)
    * There is no informative output (such as progress bars)
    * Some failure modes may cause unhelpful error messages
    * There is no concept of trusted-ssh-substituter-hosts

    This is essentially the substituter API operating on the local store,

    one connection open for multiple instances of the substituter.

    GNU Make 3.81 compatibility

    3.81 doesn't understand the ‘define foo =’ syntax, which was added in
    3.82.  So use ‘define foo’ instead.

    Fix assertion failure in ‘nix-store --load-db’

    Namely:

      nix-store: derivations.cc:242: nix::Hash nix::hashDerivationModulo(nix::StoreAPI&, nix::Derivation): Assertion `store.isValidPath(i->first)' failed.

    This happened because of the derivation output correctness check being
    applied before the references of a derivation are valid.

    actually checked whether the content of a downloaded NAR matches the
    hash specified in the manifest / NAR info file.  Urghhh...

    Support cryptographically signed binary caches

    NAR info files in binary caches can now have a cryptographic signature
    that Nix will verify before using the corresponding NAR file.

    To create a private/public key pair for signing and verifying a binary
    cache, do:

      $ openssl genrsa -out ./cache-key.sec 2048
      $ openssl rsa -in ./cache-key.sec -pubout > ./cache-key.pub

    You should also come up with a symbolic name for the key, such as
    "cache.example.org-1".  This will be used by clients to look up the
    public key.  (It's a good idea to number keys, in case you ever need
    to revoke/replace one.)

    To create a binary cache signed with the private key:

      $ nix-push --dest /path/to/binary-cache --key ./cache-key.sec --key-name cache.example.org-1

    The public key (cache-key.pub) should be distributed to the clients.
    They should have a nix.conf should contain something like:

      signed-binary-caches = *
      binary-cache-public-key-cache.example.org-1 = /path/to/cache-key.pub

    If all works well, then if Nix fetches something from the signed
    binary cache, you will see a message like:

      *** Downloading ‘http://cache.example.org/nar/7dppcj5sc1nda7l54rjc0g5l1hamj09j-subversion-1.7.11’ (signed by ‘cache.example.org-1’) to ‘/nix/store/7dppcj5sc1nda7l54rjc0g5l1hamj09j-subversion-1.7.11’...

    On the other hand, if the signature is wrong, you get a message like

      NAR info file `http://cache.example.org/7dppcj5sc1nda7l54rjc0g5l1hamj09j.narinfo' has an invalid signature; ignoring

    Signatures are implemented as a single line appended to the NAR info
    file, which looks like this:

      Signature: 1;cache.example.org-1;HQ9Xzyanq9iV...muQ==

    Thus the signature has 3 fields: a version (currently "1"), the ID of
    key, and the base64-encoded signature of the SHA-256 hash of the
    contents of the NAR info file up to but not including the Signature
    line.

    Issue #75.

    Don't use any syntactic sugar for dynamic attrs

    This doesn't change any functionality but moves some behavior out of the
    parser and into the evaluator in order to simplify the code.

    Fold dynamic binds handling into addAttr

    Since addAttr has to iterate through the AttrPath we pass it, it makes
    more sense to just iterate through the AttrNames in addAttr instead. As
    an added bonus, this allows attrsets where two dynamic attribute paths
    have the same static leading part (see added test case for an example
    that failed previously).

    Dynamic attrs

    This adds new syntax for attribute names:

    * attrs."${name}" => getAttr name attrs
    * attrs ? "${name}" => isAttrs attrs && hasAttr attrs name
    * attrs."${name}" or def => if attrs ? "${name}" then attrs."${name}" else def
    * { "${name}" = value; } => listToAttrs [{ inherit name value; }]

    Of course, it's a bit more complicated than that. The attribute chains
    can be arbitrarily long and contain combinations of static and dynamic
    parts (e.g. attrs."${foo}".bar."${baz}" or qux), which is relatively
    straightforward for the getAttrs/hasAttrs cases but is more complex for
    the listToAttrs case due to rules about duplicate attribute definitions.

    For attribute sets with dynamic attribute names, duplicate static
    attributes are detected at parse time while duplicate dynamic attributes
    are detected when the attribute set is forced. So, for example, { a =
    null; a.b = null; "${"c"}" = true; } will be a parse-time error, while
    { a = {}; "${"a"}".b = null; c = true; } will be an eval-time error
    (technically that case could theoretically be detected at parse time,
    but the general case would require full evaluation). Moreover, duplicate
    dynamic attributes are not allowed even in cases where they would be
    with static attributes ({ a.b.d = true; a.b.c = false; } is legal, but {
    a."${"b"}".d = true; a."${"b"}".c = false; } is not). This restriction
    might be relaxed in the future in cases where the static variant would
    not be an error, but it is not obvious that that is desirable.

    Finally, recursive attribute sets with dynamic attributes have the
    static attributes in scope but not the dynamic ones. So rec { a = true;
    "${"b"}" = a; } is equivalent to { a = true; b = true; } but rec {
    "${"a"}" = true; b = a; } would be an error or use a from the
    surrounding scope if it exists.

    Note that the getAttr, getAttr or default, and hasAttr are all
    implemented purely in the parser as syntactic sugar, while attribute
    sets with dynamic attribute names required changes to the AST to be
    implemented cleanly.

    This is an alternative solution to and closes #167

    Add the ExprBuiltin Expr type to the AST

    Certain desugaring schemes may require the parser to use some builtin
    function to do some of the work (e.g. currently `throw` is used to
    lazily cause an error if a `<>`-style path is not in the search path)
    Unfortunately, these names are not reserved keywords, so an expression
    that uses such a syntactic sugar will not see the expected behavior
    (see tests/lang/eval-okay-redefine-builtin.nix for an example).

    This adds the ExprBuiltin AST type, which when evaluated uses the value
    from the rootmost variable scope (which of course is initialized
    internally and can't shadow any of the builtins).

    Checking the command line for GC roots means that

    will fail because $path is now a root because it's mentioned on the

    perl: Call loadConfFile() in doInit to avoid screwing sqlite journal mode.

    If the database is opened through perl bindings (and even though nix.conf has
    use-sqlite-wal set to false), the database is automatically converted into WAL
    mode. This makes the next nix process to access the database convert it back to
    "truncate". If the database is still open at the time in wal mode by the perl
    program, this fails and crashes the nix doing the wal -> truncate conversion.

    not libutil, then ld would report undefined symbols in libstore
    because it was looking at Glibc's libutil).

    Fix segfault on Darwin

    Ever since SQLite in Nixpkgs was updated to 3.8.0.2, Nix has randomly
    segfaulted on Darwin:

      http://hydra.nixos.org/build/6175515
      http://hydra.nixos.org/build/6611038

    It turns out that this is because the binary cache substituter somehow
    ends up loading two versions of SQLite: the one in Nixpkgs and the
    other from /usr/lib/libsqlite3.dylib.  It's not exactly clear why the
    latter is loaded, but it appears to be because WWW::Curl indirectly loads
    /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation,
    which in turn seems to load /usr/lib/libsqlite3.dylib.  This leads to
    a segfault when Perl exits:

      #0  0x00000001010375f4 in sqlite3_finalize ()
      #1  0x000000010125806e in sqlite_st_destroy ()
      #2  0x000000010124bc30 in XS_DBD__SQLite__st_DESTROY ()
      #3  0x00000001001c8155 in XS_DBI_dispatch ()
      ...
      #14 0x0000000100023224 in perl_destruct ()
      #15 0x0000000100000d6a in main ()
      ...

    The workaround is to explicitly load DBD::SQLite before WWW::Curl.

    We already have some primops for determining the type of a value, such

    Rather than adding more isBla functions, the generic typeOf function
    returns a string representing the type of the argument (e.g. "int").

    nix-shell: Play nicely with non-interactive shells

    nix-shell with the --command flag might be used non-interactively, but
    if bash starts non-interactively (i.e. with stdin or stderr not a
    terminal), it won't source the script given in --rcfile. However, in
    that case it *will* source the script found in $BASH_ENV, so we can use
    that instead.

    Also, don't source ~/.bashrc in a non-interactive shell (detectable by
    checking the PS1 env var)

    Fold two stack trace messages in derivations

    Combined with the previous changes, stack traces involving derivations
    are now much less verbose, since something like

      while evaluating the builtin function `getAttr':
      while evaluating the builtin function `derivationStrict':
      while instantiating the derivation named `gtk+-2.24.20' at `/home/eelco/Dev/nixpkgs/pkgs/development/libraries/gtk+/2.x.nix:11:3':
      while evaluating the derivation attribute `propagatedNativeBuildInputs' at `/home/eelco/Dev/nixpkgs/pkgs/stdenv/generic/default.nix:78:17':
      while evaluating the attribute `outPath' at `/nix/store/212ngf4ph63mp6p1np2bapkfikpakfv7-nix-1.6/share/nix/corepkgs/derivation.nix:18:9':
      ...

    now reads

      while evaluating the attribute `propagatedNativeBuildInputs' of the derivation `gtk+-2.24.20' at `/home/eelco/Dev/nixpkgs/pkgs/development/libraries/gtk+/2.x.nix:11:3':

    Ensure proper type checking/coercion of "${expr}"

    Now we only rewrite "${expr}" to expr if expr is a string literal.

    Add a test for type correctness of antiquotes

    Antiquotes should evaluate to strings or paths.  This is usually
    checked, except in the case where the antiquote makes up the entire
    string, as in "${expr}".  This is optimised to expr, which discards
    the runtime type checks / coercions.

    Revert the behaviour of antiquoted paths to pre-Nix 1.6

    Commit 159e621d1a9c4391b53f3d822109c36931934698 accidentally changed
    the behaviour of antiquoted paths, e.g.

      "${/foo}/bar"

    used to evaluate to "/nix/store/<hash>-foo/bar" (where /foo gets
    copied to the store), but in Nix 1.6 it evaluates to "/foo/bar".  This
    is inconsistent, since

      " ${/foo}/bar"

    evaluates to " /nix/store/<hash>-foo/bar".  So revert to the old
    behaviour.

    Don't wrap read-only queries in a transaction

    There is no risk of getting an inconsistent result here: if the ID
    returned by queryValidPathId() is deleted from the database
    concurrently, subsequent queries involving that ID will simply fail
    (since IDs are never reused).

    Print a distinct warning for SQLITE_PROTOCOL

commit d05bf044441dbf8e000036d545df9689bdec0b72
Author: Eelco Dolstra <eelco.dolstra@logicblox.com>
Date:   Wed Oct 16 14:03:22 2013 +0200

    Treat SQLITE_PROTOCOL as SQLITE_BUSY

    In the Hydra build farm we fairly regularly get SQLITE_PROTOCOL errors
    (e.g., "querying path in database: locking protocol").  The docs for
    this error code say that it "is returned if some other process is
    messing with file locks and has violated the file locking protocol
    that SQLite uses on its rollback journal files."  However, the SQLite
    source code reveals that this error can also occur under high load:

      if( cnt>5 ){
        int nDelay = 1;                      /* Pause time in microseconds */
        if( cnt>100 ){
          VVA_ONLY( pWal->lockError = 1; )
          return SQLITE_PROTOCOL;
        }
        if( cnt>=10 ) nDelay = (cnt-9)*238;  /* Max delay 21ms. Total delay 996ms */
        sqlite3OsSleep(pWal->pVfs, nDelay);
      }

    i.e. if certain locks cannot be not acquired, SQLite will retry a
    number of times before giving up and returing SQLITE_PROTOCOL.  The
    comments say:

      Circumstances that cause a RETRY should only last for the briefest
      instances of time.  No I/O or other system calls are done while the
      locks are held, so the locks should not be held for very long. But
      if we are unlucky, another process that is holding a lock might get
      paged out or take a page-fault that is time-consuming to resolve,
      during the few nanoseconds that it is holding the lock.  In that case,
      it might take longer than normal for the lock to free.
      ...
      The total delay time before giving up is less than 1 second.

    On a heavily loaded machine like lucifer (the main Hydra server),
    which often has dozens of processes waiting for I/O, it seems to me
    that a page fault could easily take more than a second to resolve.
    So, let's treat SQLITE_PROTOCOL as SQLITE_BUSY and retry the
    transaction.

    Issue NixOS/hydra#14.

    Nixpkgs's stdenv setup script sets the "nullglob" option, but doing so

    this may break stdenv functions in subtle ways...

    Treat undefined variable errors consistently

    Previously, a undefined variable inside a "with" caused an EvalError
    (which can be caught), while outside, it caused a ParseError (which
    cannot be caught).  Now both cause an UndefinedVarError (which cannot
    be caught).

    Don't apply the CPU affinity hack to nix-shell (and other Perl programs)

    As discovered by Todd Veldhuizen, the shell started by nix-shell has
    its affinity set to a single CPU.  This is because nix-shell connects
    to the Nix daemon, which causes the affinity hack to be applied.  So
    we turn this off for Perl programs.

    nix-env -i: Add a flag ‘--remove-all’ / ‘-r’

    This is equivalent to running ‘nix-env -e '*'’ first, except that it
    happens in a single transaction.  Thus, ‘nix-env -i pkgs...’ replaces
    the profile with the specified set of packages.

    The main motivation is to support declarative package management
    (similar to environment.systemPackages in NixOS).  That is, if you
    have a specification ‘profile.nix’ like this:

      with import <nixpkgs> {};
      [ thunderbird
        geeqie
        ...
      ]

    then after any change to ‘profile.nix’, you can run:

      $ nix-env -f profile.nix -ir

    to update the profile to match the specification.  (Without the ‘-r’
    flag, if you remove a package from ‘profile.nix’, it won't be removed
    from the actual profile.)

    Suggested by @zefhemel.

    Work on Values instead of Exprs

    This prevents some duplicate evaluation in nix-env and
    nix-instantiate.

    Also, when traversing ~/.nix-defexpr, only read regular files with the
    extension .nix.  Previously it was reading files like
    .../channels/binary-caches/<name>.  The only reason this didn't cause
    problems is pure luck (namely, <name> shadows an actual Nix
    expression, the binary-caches files happen to be syntactically valid
    Nix expressions, and we iterate over the directory contents in just
    the right order).

    Simplify inherited attribute handling

    This reduces the difference between inherited and non-inherited
    attribute handling to the choice of which env to use (in recs and lets)
    by setting the AttrDef::e to a new ExprVar in the parser rather than
    carrying a separate AttrDef::v VarRef member.

    As an added bonus, this allows inherited attributes that inherit from a
    with to delay forcing evaluation of the with's attributes.

    corepkgs/nar.nix: Prefer local builds

    nar.nix's builder depends on coreutils and nix itself being in $PATH.
    Unfortunately, there's no good way to ensure that these packages exist
    in the same place on the remote machine: The local machine may have nix
    installed in /usr, and the remote machine in /usr/local, but the
    generated nar.sh builder will refer to /usr and thus fail on the remote
    machine. This ensures that nar.sh is run on the same machine that
    instantiates it.

    Run the daemon worker on the same CPU as the client

    On a system with multiple CPUs, running Nix operations through the
    daemon is significantly slower than "direct" mode:

    $ NIX_REMOTE= nix-instantiate '<nixos>' -A system
    real    0m0.974s
    user    0m0.875s
    sys     0m0.088s

    $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system
    real    0m2.118s
    user    0m1.463s
    sys     0m0.218s

    The main reason seems to be that the client and the worker get moved
    to a different CPU after every call to the worker.  This patch adds a
    hack to lock them to the same CPU.  With this, the overhead of going
    through the daemon is very small:

    $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system
    real    0m1.074s
    user    0m0.809s
    sys     0m0.098s

    Delay evaulation of `with` attrs until a variable lookup needs them

    Evaluation of attribute sets is strict in the attribute names, which
    means immediate evaluation of `with` attribute sets rules out some
    potentially interesting use cases (e.g. where the attribute names of one
    set depend in some way on another but we want to bring those names into
    scope for some values in the second set).

    The major example of this is overridable self-referential package sets
    (e.g. all-packages.nix). With immediate `with` evaluation, the only
    options for such sets are to either make them non-recursive and
    explicitly use the name of the overridden set in non-overridden one
    every time you want to reference another package, or make the set
    recursive and use the `__overrides` hack. As shown in the test case that
    comes with this commit, though, delayed `with` evaluation allows a nicer
    third alternative.

    Detect stack overflows

    Previously, if the Nix evaluator gets a stack overflow due to a deep
    or infinite recursion in the Nix expression, the user gets an
    unhelpful message ("Segmentation fault") that doesn't indicate that
    the problem is in the user's code rather than Nix itself.  Now it
    prints:

      error: stack overflow (possible infinite recursion)

    This only works on x86_64-linux and i686-linux.

    Fixes #35.

    killUser: Don't let the child kill itself on Apple

    The kill(2) in Apple's libc follows POSIX semantics, which means that
    kill(-1, SIGKILL) will kill the calling process too. Since nix has no
    way to distinguish between the process successfully killing everything
    and the process being killed by a rogue builder in that case, it can't
    safely conclude that killUser was successful.

    Luckily, the actual kill syscall takes a parameter that determines
    whether POSIX semantics are followed, so we can call that syscall
    directly and avoid the issue on Apple.

    This reverts commit 69b8f9980f39c14a59365a188b300a34d625a2cd.

    The timeout should be enforced remotely.  Otherwise, if the garbage
    collector is running either locally or remotely, if will block the
    build or closure copying for some time.  If the garbage collector
    takes too long, the build may time out, which is not what we want.
    Also, on heavily loaded systems, copying large paths to and from the
    remote machine can take a long time, also potentially resulting in a
    timeout.

    Fix a security bug in hash rewriting

    Before calling dumpPath(), we have to make sure the files are owned by
    the build user.  Otherwise, the build could contain a hard link to
    (say) /etc/shadow, which would then be read by the daemon and
    rewritten as a world-readable file.

    This only affects systems that don't have hard link restrictions

    In repair mode, update the hash of rebuilt paths

    Otherwise subsequent invocations of "--repair" will keep rebuilding
    the path.  This only happens if the path content differs between
    builds (e.g. due to timestamps).

    Replace $NIX_DEBUG_SUBST with an option ‘debug-subst’

    Thus passing ‘--option debug-subst 1’ allows daemon users to turn on
    debug info and see what the substituter is doing.

    will print a message to that effect.

    build-remote.pl: Allow a machine to refuse a build

    Before selecting a machine, build-remote.pl will try to run the
    command "nix-builds-inhibited" on the machine.  If this command exists
    and returns a 0 exit code, then the machine won't be used.  It's up to
    the user to provide this command, but it would typically be a script
    that checks whether there is enough disk space and whether the load is
    not too high.

    Don't pass --timeout / --max-silent-time to the remote builder.
    Instead, let the local Nix process terminate the build if it exceeds a

    gives better error reporting (since the timeout message from the
    remote side wasn't properly propagated) and handles non-Nix problems
    like SSH hangs.

    Fix --timeout

    I'm not sure if it has ever worked correctly.  The line "lastWait =

    Note that the timeout is now per build, as documented ("the maximum
    number of seconds that a builder can run").

    makeStoreWritable: Ask forgiveness, not permission

    It is surprisingly impossible to check if a mountpoint is a bind mount
    on Linux, and in my previous commit I forgot to check if /nix/store was
    even a mountpoint at all. statvfs.f_flag is not populated with MS_BIND
    (and even if it were, my check was wrong in the previous commit).

    Luckily, the semantics of mount with MS_REMOUNT | MS_BIND make both
    checks unnecessary: if /nix/store is not a mountpoint, then mount will
    fail with EINVAL, and if /nix/store is not a bind-mount, then it will
    not be made writable. Thus, if /nix/store is not a mountpoint, we fail
    immediately (since we don't know how to make it writable), and if
    /nix/store IS a mountpoint but not a bind-mount, we fail at first write
    (see below for why we can't check and fail immediately).

    Note that, due to what is IMO buggy behavior in Linux, calling mount
    with MS_REMOUNT | MS_BIND on a non-bind readonly mount makes the
    mountpoint appear writable in two places: In the sixth (but not the
    10th!) column of mountinfo, and in the f_flags member of struct statfs.
    All other syscalls behave as if the mount point were still readonly (at
    least for Linux 3.9-rc1, but I don't think this has changed recently or
    is expected to soon). My preferred semantics would be for MS_REMOUNT |
    MS_BIND to fail on a non-bind mount, as it doesn't make sense to remount
    a non bind-mount as a bind mount.

    makeStoreWritable: Use statvfs instead of /proc/self/mountinfo to find out if /nix/store is a read-only bind mount

    /nix/store could be a read-only bind mount even if it is / in its own filesystem, so checking the 4th field in mountinfo is insufficient.

    Security: Don't allow builders to change permissions on files they don't own

    It turns out that in multi-user Nix, a builder may be able to do

      ln /etc/shadow $out/foo

    Afterwards, canonicalisePathMetaData() will be applied to $out/foo,
    causing /etc/shadow's mode to be set to 444 (readable by everybody but
    writable by nobody).  That's obviously Very Bad.

    Fortunately, this fails in NixOS's default configuration because
    /nix/store is a bind mount, so "ln" will fail with "Invalid
    cross-device link".  It also fails if hard-link restrictions are
    enabled, so a workaround is:

      echo 1 > /proc/sys/fs/protected_hardlinks

    The solution is to check that all files in $out are owned by the build
    user.  This means that innocuous operations like "ln
    ${pkgs.foo}/some-file $out/" are now rejected, but that already failed
    in chroot builds anyway.

    Make "${./path} ..." evaluate to a string, not a path

    Wacky string coercion semantics caused expressions like

      exec = "${./my-script} params...";

    to evaluate to a path (‘/path/my-script params’), because
    anti-quotations are desuged to string concatenation:

      exec = ./my-script + " params...";

    By constrast, adding a space at the start would yield a string as
    expected:

      exec = " ${./my-script} params...";

    Now the first example also evaluates to a string.

    infinite recursions for sure, etc.

    Also, move directories to /nix/store/trash instead of renaming them to
    /nix/store/bla-gc-<pid>.  Then we can just delete /nix/store/trash at
    the end.

    If gc-keep-derivations is set, only keep the actual deriver

    This prevents zillions of derivations from being kept, and fixes an
    infinite recursion in the garbage collector (due to an obscure cycle

    Produce an xz-compressed tarball

    Footnote: doing "make dist-gzip dist-xz" doesn't work with Automake;
    you have to do "make dist-gzip; dist-xz".  That's because the dist-*
    targets delete the temporary distdir at the end.

    Optionally ignore null-valued derivation attributes

    This allows adding attributes like

      attr = if stdenv.system == "bla" then something else null;

    without changing the resulting derivation on non-<bla> platforms.

    We once considered adding a special "ignore" value for this purpose,
    but using null seems more elegant.

    Add builtin constants ‘langVersion’ and ‘nixVersion’

    The integer constant ‘langVersion’ denotes the current language
    version.  It gets increased every time a language feature is
    added/changed/removed.  It's currently 1.

    The string constant ‘nixVersion’ contains the current Nix version,
    e.g. "1.2pre2980_9de6bc5".

Date:   Mon Nov 26 17:15:09 2012 +0100

    Only substitute wanted outputs of a derivation

    If a derivation has multiple outputs, then we only want to download
    those outputs that are actuallty needed.  So if we do "nix-build -A
    openssl.man", then only the "man" output should be downloaded.
    Likewise if another package depends on ${openssl.man}.

    The tricky part is that different derivations can depend on different
    outputs of a given derivation, so we may need to restart the
    corresponding derivation goal if that happens.

Author: Eelco Dolstra <eelco.dolstra@logicblox.com>
Date:   Mon Nov 26 15:39:10 2012 +0100

    Make "nix-build -A <derivation>.<output>" do the right thing

    For example, given a derivation with outputs "out", "man" and "bin":

      $ nix-build -A pkg

    produces ./result pointing to the "out" output;

      $ nix-build -A pkg.man

    produces ./result-man pointing to the "man" output;

      $ nix-build -A pkg.all

    produces ./result, ./result-man and ./result-bin;

      $ nix-build -A pkg.all -A pkg2

    produces ./result, ./result-man, ./result-bin and ./result-2.

Date:   Tue Nov 20 00:27:25 2012 +0100

    nix-store -r: Add ‘--ignore-unknown’ flag

    This flag causes paths that do not have a known substitute to be
    quietly ignored.  This is mostly useful for Charon, allowing it to
    speed up deployment by letting a machine use substitutes for all
    substitutable paths, instead of uploading them.  The latter is
    frequently faster, e.g. if the target machine has a fast Internet
    connection while the source machine is on a slow ADSL line.

    Disable use of vfork()

    vfork() is just too weird.  For instance, in this build:

      http://hydra.nixos.org/build/3330487

    the value fromHook.writeSide becomes corrupted in the parent, even
    though the child only reads from it.  At -O0 the problem goes away.
    Probably the child is overriding some spilled temporary variable.

    If I get bored I may implement using posix_spawn() instead.

    getDerivation(): Don't always quietly ignore assertion failure

    Ignoring assertion failures makes some sense for nix-env -qa, but not
    for nix-instantiate/nix-build or hydra-eval-jobs.

    Add operation ‘nix-store --repair-path’

    This operation allows fixing corrupted or accidentally deleted store
    paths by redownloading them using substituters, if available.

    Since the corrupted path cannot be replaced atomically, there is a
    very small time window (one system call) during which neither the old
    (corrupted) nor the new (repaired) contents are available.  So
    repairing should be used with some care on critical packages like
    Glibc.

    Allow dashes in identifiers

    In Nixpkgs, the attribute in all-packages.nix corresponding to a
    package is usually equal to the package name.  However, this doesn't
    work if the package contains a dash, which is fairly common.  The
    convention is to replace the dash with an underscore (e.g. "dbus-lib"
    becomes "dbus_glib"), but that's annoying.  So now dashes are valid in
    variable / attribute names, allowing you to write:

      dbus-glib = callPackage ../development/libraries/dbus-glib { };

    and

      buildInputs = [ dbus-glib ];

    Since we don't have a negation or subtraction operation in Nix, this
    is unambiguous.

    Remove setting of the immutable bit

    Using the immutable bit is problematic, especially in conjunction with
    store optimisation.  For instance, if the garbage collector deletes a
    file, it has to clear its immutable bit, but if the file has
    additional hard links, we can't set the bit afterwards because we
    don't know the remaining paths.

    So now that we support having the entire Nix store as a read-only
    mount, we may as well drop the immutable bit.  Unfortunately, we have
    to keep the code to clear the immutable bit for backwards
    compatibility.

    Support having /nix/store as a read-only bind mount

    It turns out that the immutable bit doesn't work all that well.  A
    better way is to make the entire Nix store a read-only bind mount,
    i.e. by doing

      $ mount --bind /nix/store /nix/store
      $ mount -o remount,ro,bind /nix/store

    (This would typically done in an early boot script, before anything
    from /nix/store is used.)

    Since Nix needs to be able to write to the Nix store, it now detects
    if /nix/store is a read-only bind mount and then makes it writable in
    a private mount namespace.

    Put a time-to-live on negative binary cache lookups

    Negative lookups are purged from the DB after a day, at most once per
    day.  However, for non-"have" lookups (e.g. all except "nix-env
    -qas"), negative lookups are ignored after one hour.  This is to
    ensure that you don't have to wait a day for an operation like
    "nix-env -i" to start using new binaries in the cache.

    Should probably make this configurable.

    Handle gc-keep-outputs and gc-keep-derivations both enabled

    If the options gc-keep-outputs and gc-keep-derivations are both
    enabled, you can get a cycle in the liveness graph.  There was a hack
    to handle this, but it didn't work with multiple-output derivations,
    causing the garbage collector to fail with errors like ‘error: cannot
    delete path `...' because it is in use by `...'’.  The garbage
    collector now handles strongly connected components in the liveness
    graph as a unit and decides whether to delete all or none of the paths
    in an SCC.

    Support building a derivation if some outputs are already valid

    This handles the chroot and build hook cases, which are easy.
    Supporting the non-chroot-build case will require more work (hash
    rewriting!).

    Issue #21.

    Include config.h before any other header

    "config.h" must be included first, because otherwise the compiler
    might not see the right value of _FILE_OFFSET_BITS.  We've had this
    before; see 705868a8a96a10f70e629433cfffc2d5cd2703eb.  In this case,
    GCC would compute a different address for ‘settings.useSubstitutes’ in
    misc.cc because of the off_t in ‘settings’.

    Include the output name in the GC root link

    Output names are now appended to resulting GC symlinks, e.g. by
    nix-build.  For backwards compatibility, if the output is named "out",
    nothing is appended.  E.g. doing "nix-build -A foo" on a derivation
    that produces outputs "out", "bin" and "dev" will produce symlinks
    "./result", "./result-bin" and "./result-dev", respectively.

    Add a "filter" primop

    Evaluation of a NixOS configuration spends quite a lot of time in the
    "filter" function in Nixpkgs.  As implemented in Nixpkgs, this is a
    O(n^2) operation, so it's a good candidate for providing a more
    efficient (i.e. primop) implementation.  Using it gives a ~10% speed
    increase and a significant reduction in the number of evaluations.

    nix-channel: Use binary caches advertised by channels

    Channels can now advertise a binary cache by creating a file
    <channel-url>/binary-cache-url.  The channel unpacker puts these in
    its "binary-caches" subdirectory.  Thus, the URLS of the binary caches
    for the channels added by root appear in
    /nix/var/nix/profiles/per-user/eelco/channels/binary-caches/*.  The
    binary cache substituter reads these and adds them to the list of
    binary caches.

    nix-env: Ignore manifest.nix when recursing into ~/.nix-defexpr

    Channels are implemented using a profile now, and profiles contain a
    manifest.nix file.  This should be ignored to prevent bogus packages
    from showing up in nix-env.

    Allow a binary cache to declare that it doesn't support "nix-env -qas"

    Querying all substitutable paths via "nix-env -qas" is potentially
    hard on a server, since it involves sending thousands of HEAD
    requests.  So a binary cache must now have a meta-info file named
    "nix-cache-info" that specifies whether the server wants this.  It
    also specifies the store prefix so that we don't send useless queries
    to a binary cache for a different store prefix.

    Since SubstitutionGoal::finished() in build.cc computes the hash
    anyway, we can prevent the inefficiency of computing the hash twice by
    letting the substituter tell Nix about the expected hash, which can
    then verify it.

    import: If the path is a valid .drv file, parse it and generate a derivation attrset.

    The generated attrset has drvPath and outPath with the right string context, type 'derivation', outputName with
    the right name, all with a list of outputs, and an attribute for each output.

    I see three uses for this (though certainly there may be more):

    * Using derivations generated by something besides nix-instantiate (e.g. guix)

    * Allowing packages provided by channels to be used in nix expressions. If a channel installed a valid deriver
      for each package it provides into the store, then those could be imported and used as dependencies or installed
      in environment.systemPackages, for example.

    * Enable hydra to be consistent in how it treats inputs that are outputs of another build. Right now, if an
      input is passed as an argument to the job, it is passed as a derivation, but if it is accessed via NIX_PATH
      (i.e. through the <> syntax), then it is a path that can be imported. This is problematic because the build
      being depended upon may have been built with non-obvious arguments passed to its jobset file. With this
      feature, hydra can just set the name of that input to the path to its drv file in NIX_PATH

    Garbage collect unused links in /nix/store/.links

    Incremental optimisation requires creating links in /nix/store/.links
    to all files in the store.  However, this means that if we delete a
    store path, no files are actually deleted because links in
    /nix/store/.links still exists.  So we need to check /nix/store/.links
    for files with a link count of 1 and delete them.

    optimiseStore(): Use a content-addressed file store in /nix/store/.links

    optimiseStore() now creates persistent, content-addressed hard links
    in /nix/store/.links.  For instance, if it encounters a file P with
    hash H, it will create a hard link

      P' = /nix/store/.link/<H>

    to P if P' doesn't already exist; if P' exist, then P is replaced by a
    hard link to P'.  This is better than the previous in-memory map,
    because it had the tendency to unnecessarily replace hard links with a
    hard link to whatever happened to be the first file with a given hash
    it encountered.  It also allows on-the-fly, incremental optimisation.

    Add function queryPathFromHashPart()

    To implement binary caches efficiently, Hydra needs to be able to map
    the hash part of a store path (e.g. "gbg...zr7") to the full store
    path (e.g. "/nix/store/gbg...kzr7-subversion-1.7.5").  (The binary
    cache mechanism uses hash parts as a key for looking up store paths to
    ensure privacy.)  However, doing a search in the Nix store for
    /nix/store/<hash>* is expensive since it requires reading the entire
    directory.  queryPathFromHashPart() prevents this by doing a cheap
    database lookup.

    download-from-binary-cache: Use HEAD requests if possible

    In "nix-env -qas", we don't need the substitute info, we just need to
    know if it exists.  This can be done using a HTTP HEAD request, which
    saves bandwidth.

    Note however that curl currently has a bug that prevents it from
    reusing HTTP connections if HEAD requests return a 404:

    https://sourceforge.net/tracker/?func=detail&aid=3542731&group_id=976&atid=100976

    Without the patch attached to the issue, using HEAD is actually quite
    a bit slower than GET.

    Replace hasSubstitutes() with querySubstitutablePaths()

    querySubstitutablePaths() takes a set of paths, so this greatly
    reduces daemon <-> client latency.

    Add a function queryValidPaths()

    queryValidPaths() combines multiple calls to isValidPath() in one.
    This matters when using the Nix daemon because it reduces latency.
    For instance, on "nix-env -qas \*" it reduces execution time from 5.7s
    to 4.7s (which is indistinguishable from the non-daemon case).

    download-from-binary-cache: parallelise fetching of NAR info files

    Getting substitute information using the binary cache substituter has
    non-trivial latency overhead.  A package or NixOS system configuration
    can have hundreds of dependencies, and in the worst case (when the
    local info cache is empty) we have to do a separate HTTP request for
    each of these.  If the ping time to the server is t, getting N info
    files will take tN seconds; e.g., with a ping time of 0.1s to
    nixos.org, sequentially downloading 1000 info files (a typical NixOS
    config) will take at least 100 seconds.

    To fix this problem, the binary cache substituter can now perform
    requests in parallel.  This required changing the substituter
    interface to support a function querySubstitutablePathInfos() that
    queries multiple paths at the same time, and rewriting queryMissing()
    to take advantage of parallelism.  (Due to local caching,
    parallelising queryMissing() is sufficient for most use cases, since
    it's almost always called before building a derivation and thus fills
    the local info cache.)

    For example, parallelism speeds up querying all 1056 paths in a
    particular NixOS system configuration from 116s to 2.6s.  It works so
    well because the eccentricity of the top-level derivation in the
    dependency graph is only 9.  So we only need 10 round-trips (when
    using an unlimited number of parallel connections) to get everything.

    Currently we do a maximum of 150 parallel connections to the server.
    Thus it's important that the binary cache server (e.g. nixos.org) has
    a high connection limit.  Alternatively we could use HTTP pipelining,
    but WWW::Curl doesn't support it and libcurl has a hard-coded limit of
    5 requests per pipeline.

    download-from-binary-cache: use WWW::Curl

    Using WWW::Curl rather than running an external curl process for every
    NAR info file halves the time it takes to get info thanks to libcurl's
    support for persistent HTTP connections.  (We save a roundtrip per
    file.)  But the real gain will come from using parallel and/or
    pipelined requests.

    Use XZ compression in binary caches

    XZ compresses significantly better than bzip2.  Here are the
    compression ratios and execution times (using 4 cores in parallel) on
    my /var/run/current-system (3.1 GiB):

      bzip2: total compressed size 849.56 MiB, 30.8% [2m08]
      xz -6: total compressed size 641.84 MiB, 23.4% [6m53]
      xz -7: total compressed size 621.82 MiB, 22.6% [7m19]
      xz -8: total compressed size 599.33 MiB, 21.8% [7m18]
      xz -9: total compressed size 588.18 MiB, 21.4% [7m40]

    Note that compression takes much longer.  More importantly, however,
    decompression is much faster:

      bzip2: 1m47.274s
      xz -6: 0m55.446s
      xz -7: 0m54.119s
      xz -8: 0m52.388s
      xz -9: 0m51.842s

    The only downside to using -9 is that decompression takes a fair
    amount (~65 MB) of memory.

    nix-push: create a manifest-less binary cache

    Manifests are a huge pain, since users need to run nix-pull directly
    or indirectly to obtain them.  They tend to be large and lag behind
    the available binaries; also, the downloaded manifests in
    /nix/var/nix/manifest need to be in sync with the Nixpkgs sources.  So
    we want to get rid of them.

    The idea of manifest-free operation works as follows.  Nix is
    configured with a set of URIs of binary caches, e.g.

      http://nixos.org/binary-cache

    Whenever Nix needs a store path X, it checks each binary cache for the
    existence of a file <CACHE-URI>/<SHA-256 hash of X>.narinfo, e.g.

      http://nixos.org/binary-cache/bi1gh9...ia17.narinfo

    The .narinfo file contains the necessary information about the store
    path that was formerly kept in the manifest, i.e., (relative) URI of
    the compressed NAR, references, size, hash, etc.  For example:

      StorePath: /nix/store/xqp4l88cr9bxv01jinkz861mnc9p7qfi-neon-0.29.6
      URL: 1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd.nar.bz2
      CompressedHash: sha256:1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd
      CompressedSize: 202542
      NarHash: sha256:1af26536781e6134ab84201b33408759fc59b36cc5530f57c0663f67b588e15f
      NarSize: 700440
      References: 043zrsanirjh8nbc5vqpjn93hhrf107f-bash-4.2-p24 cj7a81wsm1ijwwpkks3725661h3263p5-glibc-2.13 ...
      Deriver: 4idz1bgi58h3pazxr3akrw4fsr6zrf3r-neon-0.29.6.drv
      System: x86_64-linux

    Nix then knows that it needs to download

      http://nixos.org/binary-cache/1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd.nar.bz2

    to substitute the store path.

    Note that the store directory is omitted from the References and
    Deriver fields to save space, and that the URL can be relative to the
    binary cache prefix.

    This patch just makes nix-push create binary caches in this format.
    The next step is to make a substituter that supports them.

    nix-store -r: do substitutions in parallel

    I.e. when multiple non-derivation arguments are passed to ‘nix-store
    -r’ to be substituted, do them in parallel.

    Mount an empty /dev/shm tmpfs in the chroot

    This ensures that whatever the builder writes in /dev/shm is
    automatically cleaned up.

    Check the return code of the clone() call

    When using chroots, use a private PID namespace

    In a private PID namespace, processes have PIDs that are separate from
    the rest of the system.  The initial child gets PID 1.  Processes in
    the chroot cannot see processes outside of the chroot.  This improves
    isolation between builds.  However, processes on the outside can see
    processes in the chroot and send signals to them (if they have
    appropriate rights).

    Since the builder gets PID 1, it serves as the reaper for zombies in
    the chroot.  This might turn out to be a problem.  In that case we'll
    need to have a small PID 1 process that sits in a loop calling wait().

    Use a private UTS namespace to provide a deterministic host/domain name to builders

    In chroot builds, set the host name to "localhost" and the domain name
    to "(none)" (the latter being the kernel's default).  This improves
    determinism a bit further.

    P.S. I have to idea what UTS stands for.

    In chroot builds, use a private SysV IPC namespace

    This improves isolation a bit further, and it's just one extra flag in
    the unshare() call.

    P.S. It would be very cool to use CLONE_NEWPID (to put the builder in
    a private PID namespace) as well, but that's slightly more risky since
    having a builder start as PID 1 may cause problems.

    In chroot builds, use a private network namespace

    On Linux it's possible to run a process in its own network namespace,
    meaning that it gets its own set of network interfaces, disjunct from
    the rest of the system.  We use this to completely remove network
    access to chroot builds, except that they get a private loopback
    interface.  This means that:

    - Builders cannot connect to the outside network or to other processes
      on the same machine, except processes within the same build.

    - Vice versa, other processes cannot connect to processes in a chroot
      build, and open ports/connections do not show up in "netstat".

    - If two concurrent builders try to listen on the same port (e.g. as
      part of a test), they no longer conflict with each other.

    This was inspired by the "PrivateNetwork" flag in systemd.

    Support socket-based, on-demand activation of the Nix daemon with systemd

    Systemd can start the Nix daemon on demand when the Nix daemon socket
    is first accessed.  This is signalled through the LISTEN_FDS
    environment variable, so all we need to do is check for that and then
    use file descriptor 3 as the listen socket instead of creating one
    ourselves.

    Reserve some disk space for the garbage collector

    We can't open a SQLite database if the disk is full.  Since this
    prevents the garbage collector from running when it's most needed, we

    collection.  This actually revives some old code from the Berkeley DB
    days.

    Generate binary tarballs for installing Nix

    For several platforms we don't currently have "native" Nix packages
    (e.g. Mac OS X and FreeBSD).  This provides the next best thing: a
    tarball containing the closure of Nix, plus a simple script
    "nix-finish-install" that initialises the Nix database, registers the
    paths in the closure as valid, and runs "nix-env -i /path/to/nix" to
    initialise the user profile.

    The tarball must be unpacked in the root directory.  It creates
    /nix/store/... and /usr/bin/nix-finish-install.  Typical installation
    is as follows:

      $ cd /
      $ tar xvf /path/to/nix-1.1pre1234_abcdef-x86_64-linux.tar.bz2
      $ nix-finish-install
      (if necessary add ~/.nix-profile/etc/profile.d/nix.sh to the shell
      login scripts)

    After this, /usr/bin/nix-finish-install can be deleted, if desired.

    The downside to the binary tarball is that it's pretty big (~55 MiB
    for x86_64-linux).

    Mandatory features are features that MUST be present in a derivation's

    testing, where we have a dedicated machine to run performance tests
    (and nothing else).  Then we would add the label "perf" to the
    machine's mandatory features and to the performance testing
    derivations.

    Handle EPERM when creating a hard link for the chroot

    There is a race condition when doing parallel builds with chroots and
    the immutable bit enabled.  One process may call makeImmutable()
    before the other has called link(), in which case link() will fail
    with EPERM.  We could retry or wrap the operation in a lock, but since
    this condition is rare and I'm lazy, we just use the existing copy
    fallback.

    Fixes #9.

    nix-channel improvements

    "nix-channel --add" now accepts a second argument: the channel name.
    This allows channels to have a nicer name than (say) nixpkgs_unstable.
    If no name is given, it defaults to the last component of the URL
    (with "-unstable" or "-stable" removed).

    Also, channels are now stored in a profile
    (/nix/var/nix/profiles/per-user/$USER/channels).  One advantage of
    this is that it allows rollbacks (e.g. if "nix-channel --update" gives
    an undesirable update).

    Add an option "--exclude" to filter dependencies in "nix-build --run-env"

    Sometimes when doing "nix-build --run-env" you don't want all
    dependencies to be built.  For instance, if we want to do "--run-env"
    on the "build" attribute in Hydra's release.nix (to get Hydra's build
    environment), we don't want its "tarball" dependency to be built.  So
    we can do:

      $ nix-build --run-env release.nix -A build --exclude 'hydra-tarball'

    This will skip the dependency whose name matches the "hydra-tarball"
    regular expression.  The "--exclude" option can be repeated any number
    of times.

    Delete non-directory valid paths right away

    It's unlikely that rename() is faster than unlink() on a regular file
    or symlink, so don't bother.

    Make the garbage collector more concurrent

    Make the garbage collector more concurrent by deleting valid paths
    outside the region where we're holding the global GC lock.  This
    should greatly reduce the time during which new builds are blocked,
    since the deletion accounts for the vast majority of the time spent in
    the GC.

    To ensure that this is safe, the valid paths are invalidated and
    renamed to some arbitrary path while we're holding the lock.  This
    ensures that we when we finally delete the path, it's not a (newly)
    valid or locked path.

    Add a command "nix-build --run-env" to reproduce the environment of a derivation

    This command builds or fetches all dependencies of the given
    derivation, then starts a shell with the environment variables from
    the derivation.  This shell also sources $stdenv/setup to initialise
    the environment further.

    The current directory is not changed.  Thus this is a convenient way
    to reproduce a build environment in an existing working tree.

    Existing environment variables are left untouched (unless the
    derivation overrides them).  As a special hack, the original value of
    $PATH is appended to the $PATH produced by $stdenv/setup.

    Example session:

    $ nix-build --run-env '<nixpkgs>' -A xterm
    (the dependencies of xterm are built/fetched...)
    $ tar xf $src
    $ ./configure
    $ make
    $ emacs
    (... hack source ...)
    $ make
    $ ./xterm

    have been run.

    Fix chroots builds

    Chroots are initialised by hard-linking inputs from the Nix store to
    the chroot.  This doesn't work if the input has its immutable bit set,
    because it's forbidden to create hard links to immutable files.  So
    temporarily clear the immutable bit when creating and destroying the
    chroot.

    Note that making regular files in the Nix store immutable isn't very
    reliable, since the bit can easily become cleared: for instance, if we
    run the garbage collector after running ‘nix-store --optimise’.  So
    maybe we should only make directories immutable.

    On Linux, make the Nix store really read-only by using the immutable bit

    I was bitten one time too many by Python modifying the Nix store by
    creating *.pyc files when run as root.  On Linux, we can prevent this
    by setting the immutable bit on files and directories (as in ‘chattr
    +i’).  This isn't supported by all filesystems, so it's not an error
    if setting the bit fails.  The immutable bit is cleared by the garbage
    collector before deleting a path.  The only tricky aspect is in
    optimiseStore(), since it's forbidden to create hard links to an
    immutable file.  Thus optimiseStore() temporarily clears the immutable
    bit before creating the link.

    * Pass the appropriate flags to GCC when building the Perl bindings.
      Without these, Nix fails on 32-bit Linux with Perl 5.14, with a
      rather unhelpful error message:

        Not a CODE reference at /nix/store/n6kpbacn6nn7i3i735v8j3di8aqyl07v-perl-5.14.2/lib/perl5/5.14.2/i686-linux-thread-multi/DynaLoader.pm

      This is likely because the lack of -D_FILE_OFFSET_BITS=64 causes
      various Perl structures to not match what the Perl interpreter
      expects.

    * Added a command ‘nix-store --print-env $drvpath’ that prints out the
      environment of the given derivation in a format that can be sourced
      by the shell, e.g.

      $ eval "$(nix-store --print-env $(nix-instantiate /etc/nixos/nixpkgs -A pkg))"
      $ NIX_BUILD_TOP=/tmp
      $ source $stdenv/setup

      This is especially useful to reproduce the environment used to build
      a package outside of its builder for development purposes.

      TODO: add a nix-build option to do the above and fetch the
      dependencies of the derivation as well.

      outputs.  This seems more user-friendly.

    * In the garbage collector, delete invalid paths before deleting
      unreachable paths.  This matters when using --max-freed etc.:
      unreachable paths could become reachable again, so it's nicer to
      keep them if there is "real" garbage to be deleted.  Also, don't use
      readDirectory() but read the Nix store and delete invalid paths in
      parallel.  This reduces GC latency on very large Nix stores.

    * Refactoring: move sink/source buffering into separate classes.
    * Buffer the HashSink.  This speeds up hashing a bit because it
      prevents lots of calls to the hash update functions (e.g. nix-hash
      went from 9.3s to 8.7s of user time on the closure of my
      /var/run/current-system).

    * Buffer reads in FdSource.  Together with write buffering, this
      significantly cuts down the number of syscalls (e.g., for "nix-store
      -qR /var/run/current-system" via the daemon, it reduced the number
      of syscalls in the client from 29134 to 4766 and in the daemon from
      44266 to 20666).

    * Add an API function exportPaths() that provides the functionality of
      ‘nix-store --export’.
    * Add a Perl module that provides the functionality of
      ‘nix-copy-closure --to’.  This is used by build-remote.pl so it no
      longer needs to start a separate nix-copy-closure process.  Also, it
      uses the Perl API to do the export, so it doesn't need to start a
      separate nix-store process either.  As a result, nix-copy-closure
      and build-remote.pl should no longer fail on very large closures due
      to an "Argument list too long" error.  (Note that having very many
      dependencies in a single derivation can still fail because the
      environment can become too large.  Can't be helped though.)

    * Move initialisation of variables like nixConfDir from libmain to
      libstore so that the Perl bindings can use it as well.  It's vital
      that the Perl bindings use the configuration file, because otherwise
      nix-copy-closure will fail with a ‘database locked’ message if the
      value of ‘use-sqlite-wal’ is changed from the default.

    First attempt at the output-as-derivation semantics

    For each output, this adds a corresponding attribute to the derivation that is
    the same as the derivation except for outPath, which is set to the path specific
    to that output. Additionally, an "all" attribute is added that is a list of all
    of the output derivations. This has to be done outside of derivationStrict as
    each output is itself a derivation that contains itself (and all other outputs)
    as an attribute. The derivation itself is equivalent to the first output in the
    outputs list (or "out" if that list isn't set).

        path `/nix/store/m2smyiwbxidlprfxfz4rjlvz2c3mg58y-etc' was modified! expected hash `fc87e271c5fdf179b47939b08ad13440493805584b35e3014109d04d8436e7b8', got `20f1a47281b3c0cbe299ce47ad5ca7340b20ab34246426915fce0ee9116483aa'

      All paths are checked; the exit code is 1 if any path has been
      modified, 0 otherwise.

    * Cache the result of file evaluation (i.e, memoize evalFile()).  This
      prevents files from being evaluated and stored as values multiple
      times.  For instance, evaluation of the ‘system’ attribute in NixOS
      causes ‘nixpkgs/pkgs/lib/lists.nix’ to be evaluated 2019 times.

      Caching gives a modest speedup and a decent memory footprint
      reduction (e.g., from 1.44s to 1.28s, and from 81 MiB to 59 MiB with
      GC_INITIAL_HEAP_SIZE=100000 on my system).

    * Add a Nix expression search path feature.  Paths between angle
      brackets, e.g.

        import <nixpkgs/pkgs/lib>

      are resolved by looking them up relative to the elements listed in
      the search path.  This allows us to get rid of hacks like

        import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib"

      The search path can be specified through the ‘-I’ command-line flag
      and through the colon-separated ‘NIX_PATH’ environment variable,
      e.g.,

        $ nix-build -I /etc/nixos ...

      If a file is not found in the search path, an error message is
      lazily thrown.

Date:   Wed Jul 20 18:10:47 2011 +0000

    * Fix a huuuuge security hole in the Nix daemon.  It didn't check that
      derivations added to the store by clients have "correct" output
      paths (meaning that the output paths are computed by hashing the
      derivation according to a certain algorithm).  This means that a
      malicious user could craft a special .drv file to build *any*
      desired path in the store with any desired contents (so long as the
      path doesn't already exist).  Then the attacker just needs to wait
      for a victim to come along and install the compromised path.

      For instance, if Alice (the attacker) knows that the latest Firefox
      derivation in Nixpkgs produces the path

        /nix/store/1a5nyfd4ajxbyy97r1fslhgrv70gj8a7-firefox-5.0.1

      then (provided this path doesn't already exist) she can craft a .drv
      file that creates that path (i.e., has it as one of its outputs),
      add it to the store using "nix-store --add", and build it with
      "nix-store -r".  So the fake .drv could write a Trojan to the
      Firefox path.  Then, if user Bob (the victim) comes along and does

        $ nix-env -i firefox
        $ firefox

      he executes the Trojan injected by Alice.

      The fix is to have the Nix daemon verify that derivation outputs are
      correct (in addValidPath()).  This required some refactoring to move
      the hash computation code to libstore.

    * Support multiple outputs.  A derivation can declare multiple outputs
      by setting the ‘outputs’ attribute.  For example:

        stdenv.mkDerivation {
          name = "aterm-2.5";

          src = ...;

          outputs = [ "out" "tools" "dev" ];

          configureFlags = "--bindir=$(tools)/bin --includedir=$(dev)/include";
        }

      This derivation creates three outputs, named like this:

        /nix/store/gcnqgllbh01p3d448q8q6pzn2nc2gpyl-aterm-2.5
        /nix/store/gjf1sgirwfnrlr0bdxyrwzpw2r304j02-aterm-2.5-tools
        /nix/store/hp6108bqfgxvza25nnxfs7kj88xi2vdx-aterm-2.5-dev

      That is, the symbolic name of the output is suffixed to the store
      path (except for the ‘out’ output).  Each path is passed to the
      builder through the corresponding environment variable, e.g.,
      ${tools}.

      The main reason for multiple outputs is to allow parts of a package
      to be distributed and garbage-collected separately.  For instance,
      most packages depend on Glibc for its libraries, but don't need its
      header files.  If these are separated into different store paths,
      then a package that depends on the Glibc libraries only causes the
      libraries and not the headers to be downloaded.

      The main problem with multiple outputs is that if one output exists
      while the others have been garbage-collected (or never downloaded in
      the first place), and we want to rebuild the other outputs, then
      this isn't possible because we can't clobber a valid output (it
      might be in active use).  This currently gives an error message
      like:

        error: derivation `/nix/store/1s9zw4c8qydpjyrayxamx2z7zzp5pcgh-aterm-2.5.drv' is blocked by its output paths

      There are two solutions: 1) Do the build in a chroot.  Then we don't
      need to overwrite the existing path.  2) Use hash rewriting (see the
      ASE-2005 paper).  Scary but it should work.

      This is not finished yet.  There is not yet an easy way to refer to
      non-default outputs in Nix expressions.  Also, mutually recursive
      outputs aren't detected yet and cause the garbage collector to
      crash.

    * Fix concurrency issues in download-using-manifests' handling of the
      SQLite manifest cache.  The DBI AutoCommit feature caused every
      process to have an active transaction at all times, which could
      indefinitely block processes wanting to update the manifest cache.

    * Disable fsync() in the manifest cache because we don't need
      integrity (the cache can always be recreated if it gets corrupted).

    * Allow a default value in attribute selection by writing

      (as originally proposed in
      https://mail.cs.uu.nl/pipermail/nix-dev/2009-September/002989.html).

      For instance, an expression like

        stdenv.lib.attrByPath ["features" "ckSched"] false args

      can now be written as

        args.features.ckSched or false

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Jul 6 10:58:17 2011 +0000

    * In the ‘?’ operator, allow attribute paths.  For instance, you can
      write ‘attrs ? a.b’ to test whether ‘attrs’ has an attribute ‘a’
      containing an attribute ‘b’.  This is more convenient than ‘attrs ?
      a && attrs.a ? b’.

      Slight change in the semantics: it's no longer an error if the
      left-hand side of ‘?’ is not an attribute set.  In that case it just
      returns false.  So, ‘null ? foo’ no longer throws an error.

      so for every available package, rather than those matching installed
      packages.  This was very slow and subject to assertion failures.  So
      do the check much later.  Idem for `nix-env -qab' and `nix-env -ib'.

    * Cache the manifests in /nix/var/nix/manifests in a SQLite database.
      This significantly speeds up the download-using-manifests
      substituter, especially if manifests are very large.  For instance,
      one "nix-build -A geeqie" operation that updated four packages using
      binary patches went from 18.5s to 1.6s.  It also significantly
      reduces memory use.

      The cache is kept in /nix/var/nix/manifests/cache.sqlite.  It's
      updated automatically when manifests are added to or removed from
      /nix/var/nix/manifests.  It might be interesting to have nix-pull
      store manifests directly in the DB, rather than storing them as
      separate flat files, but then we would need a command line interface
      to delete manifests from the DB.

    * `nix-store --verify --check-contents': don't hold the global GC lock

      long time to finish.  Also, fill in missing narSize fields in the DB
      while doing this.

    * Retry a transaction if SQLite returns SQLITE_BUSY.  This can happen
      even with a very long busy timeout, because SQLITE_BUSY is also
      returned to resolve deadlocks.  This should get rid of random
      "database is locked" errors.  This is kind of hard to test though.
    * Fix a horrible bug in deleteFromStore(): deletePathWrapped() should
      be called after committing the transaction, not before, because the
      commit might not succeed.

    * When checking whether a patch is applicable, for efficiency, use
      `nix-store -q --hash' to get the hash of the base path rather than
      `nix-hash'.  However, only do this for estimating the size of a
      download, not for the actual substitution, because sometimes the
      contents of store paths are modified (which they shouldn't, of
      course).

    * Store attribute sets as a vector instead of a map (i.e. a red-black
      tree).  This saves a lot of memory.  The vector should be sorted so
      that names can be looked up using binary search, but this is not the
      case yet.  (Surprisingly, looking up attributes using linear search
      doesn't have a big impact on performance.)

    * In environments, store pointers to values rather than values.  This

    * Store Value nodes outside of attribute sets.  I.e., Attr now stores
      a pointer to a Value, rather than the Value directly.  This improves
      the effectiveness of garbage collection a lot: if the Value is
      stored inside the set directly, then any live pointer to the Value
      causes all other attributes in the set to be live as well.

    * Make sure that config.h is included before the system headers,
      because it defines _FILE_OFFSET_BITS.  Without this, on
      OpenSolaris the system headers define it to be 32, and then
      the 32-bit stat() ends up being called with a 64-bit "struct
      stat", or vice versa.

      This also ensures that we get 64-bit file sizes everywhere.

    * Remove the redundant call to stat() in parseExprFromFile().
      The file cannot be a symlink because that's the exit condition
      of the loop before.

    `nix-store --verify' improvements:
    * If a path has disappeared, check its referrers first, and don't try
      to invalidate paths that have valid referrers.  Otherwise we get a
      foreign key constraint violation.
    * Read the whole Nix store directory instead of statting each valid
      path, which is slower.
    * Acquire the global GC lock.

      it requires a certain feature on the build machine, e.g.

        requiredSystemFeatures = [ "kvm" ];

      We need this in Hydra to make sure that builds that require KVM
      support are forwarded to machines that have KVM support.  Probably
      this should also be enforced for local builds.

    * Made the build hook mechanism more efficient.  Rather than starting
      the hook every time we want to ask whether we can run a remote build
      (which can be very often), we now reuse a hook process for answering
      those queries until it accepts a build.  So if there are N
      derivations to be built, at most N hooks will be started.

    * Don't link against pthreads.  This was added way back in r211
      because Berkeley DB needed it on some platforms, but we don't use
      BDB anymore.

      On FreeBSD, if you link against pthreads, then the main thread gets
      a 2 MB stack which cannot be overriden (it ignores "ulimit -s"):

        http://www.mail-archive.com/freebsd-hackers@freebsd.org/msg62445.html

      This is not enough for Nix.  For instance, the garbage collector can
      fail if there is a pathologically deep chain of references
      (http://hydra.nixos.org/build/556199).  2 MB is also not enough for
      many Nix expressions.

      Arguably the garbage collector shouldn't use recursion, because in
      NixOS unprivileged users can DOS the garbage collector by creating a
      sufficiently deeply nested chain of references.  But getting rid of
      recursion is a bit harder.

    * Use SQLite 3.7.0's write-ahead logging (WAL mode).  This is a lot
      faster than the old mode when fsyncs are enabled, because it only
      performs an fsync() when doing a checkpoint, rather than at every
      commit.  Some timings for doing a "nix-instantiate /etc/nixos/nixos
      -A system" after modifying the stdenv setup script:

        42.5s - SQLite 3.6.23 with truncate mode and fsync
         3.4s - SQLite 3.6.23 with truncate mode and no fsync
        32.1s - SQLite 3.7.0 with truncate mode and fsync
        16.8s - SQLite 3.7.0 with WAL mode and fsync, auto-checkpoint
                every 1000 pages
         8.3s - SQLite 3.7.0 with WAL mode and fsync, auto-checkpoint
                every 8192 pages
         1.7s - SQLite 3.7.0 with WAL mode and no fsync

      The default is now to use WAL mode with fsyncs.  Because WAL doesn't
      work on remote filesystems such as NFS (as it uses shared memory),
      truncate mode can be re-enabled by setting the "use-sqlite-wal"
      option to false.

    * Allow derivations to hint that they should not be built remotely
      using the build hook mechanism, by setting the derivation attribute
      "preferLocalBuild" to true.  This has a few use cases:

      - The user environment builder.  Since it just creates a bunch of
        symlinks without much computation, there is no reason to do it
        remotely.  In fact, doing it remotely requires the entire closure
        of the user environment to be copied to the remote machine, which
        is extremely wasteful.

      - `fetchurl'.  Performing the download on a remote machine and then
        copying it to the local machine involves twice as much network
        traffic as performing the download locally, and doesn't save any
        CPU cycles on the local machine.

    tests/build-hook.hook.sh: prefer more portable `...` syntax over $(...) for running sub-shells

    The /bin/sh interpreter on Solaris doesn't understand $(...) syntax for running
    sub-shells. Consequently, this test fails on Solaris. To remedy the situation,
    the script either needs to be run by /bin/bash -- which is non-standard --, or
    it needs to use the ancient but portable `...` syntax.

    Added support for passing an (impure) NIX_BUILD_CORES variable to build expressions.

    This patch adds the configuration file variable "build-cores" and the
    command line argument "--cores". These settings specify the number of
    CPU cores to utilize for parallel building within a job, i.e. by passing
    an appropriate "-j" flag to GNU Make. The default value is 1, which
    means that parallel building is *disabled*. If the number of build cores
    is specified as 0 (synonymously: "guess" or "auto"), then the actual
    value is supposed to be auto-detected by builders at run-time, i.e by
    calling the nproc(1) utility from coreutils.

    The environment variable $NIX_BUILD_CORES is available to builders, but
    the contents of that variable does *not* influence the hash that goes
    into the $out store path, i.e. the number of build cores to be utilized
    can be changed at will without requiring any re-builds.

    * An attribute set such as `{ foo = { enable = true; };
      foo.port = 23; }' now parses.  It was previously rejected, but I'm
      too lazy to implement the check.  (The only reason to reject it is
      that the reverse, `{ foo.port = 23; foo = { enable = true; }; }', is
      rejected, which is kind of ugly.)

    * Change the semantics of "with" so that inner "withs" take
      precedence, i.e. `with {x=1;}; with {x=2;}; x' evaluates to 2'.
      This has a simpler implementation and seems more natural.  There
      doesn't seem to be any code in Nixpkgs or NixOS that relies on the
      old behaviour.

    Re-add `drvPath' and `outPath' attributes to <derivation> XML nodes.

    This fixes a regression introduced in r20882 ("Add source location
    information to the XML output.").

    * src/libexpr/expr-to-xml.cc (nix::printTermAsXML): Dereference the

    * Fix blackholing.  If evaluation fails due to an assertion failure,
      then the blackhole has to be removed to ensure that repeated
      evaluation of the same value gives an assertion failure again rather
      than an "infinite recursion" error.

    * Make `derivation' lazy again for performance.  It also turns out
      that there are some places in Nixpkgs (php_configurable /
      composableDerivation, it seems) that call `derivation' with
      incorrect arguments (namely, the `name' attribute missing) but get
      away with it because of laziness.

    * Fixed the trace primop and path comparison.
    * Removed exprToString and stringToExpr because there is no ATerm
      representation to work on anymore (and exposing the internals of the
      evaluator like this is not a good idea anyway).

      slightly.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Thu Feb 18 13:14:51 2010 +0000

    * Experimental branch for using SQLite to store the Nix database.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Feb 16 00:10:39 2010 +0000

    * Since Hydra now escapes `+', `=' and `?' to %NN in URIs,
      nix-prefetch-url should unescape them, because `%' is not a valid
      character in store path names.

Date:   Wed Feb 3 21:38:41 2010 +0000

    * Revert r19797, and use a simpler solution: just don't monitor build
      hooks for silence.  It's unnecessary because the remote nix-store
      command is already monitoring the real build.

commit f859a8d3c33cc275f41d983bfeff2a21a9f88f1b
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Feb 3 21:22:57 2010 +0000

    * While waiting for a lock, print a sign of life every 5 minutes.
      This prevents remote builders from being killed by the
      `max-silent-time' inactivity monitor while they are waiting for a
      long garbage collection to finish.  This happens fairly often in the
      Hydra build farm.

    * In the build hook, if connecting to a machine fails, try the other

    * Use SSH connection sharing in the remote build script.
    * Removed the Cygwin password hack since the problem is apparently
      fixed in Visual Studio.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Feb 2 17:01:16 2010 +0000

    * Ugly hack to make `nix-channel' work on Cygwin.

commit e839802720af75e5af321b46a3921695ed696e79
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Feb 2 15:29:18 2010 +0000

    * Don't do a chdir to $tmpDir.  It's not necessary, and Windows doesn't
      support deleting the current directory.

commit 4bbbe25802ee5d625d05b9566bcc488b93974692
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Feb 2 15:28:36 2010 +0000

    * Remove most Cygwin-specific code.  Cygwin 1.7 implements advisory
      POSIX locks, and simulates Unix-style file deletion semantics
      sufficiently.  Note that this means that Nix won't work on Cygwin
      1.5 anymore.

Date:   Tue Feb 2 11:57:49 2010 +0000

    * If fdatasync() isn't available, use fsync().

commit 07ffdc28629e537c3811f86b83a93655b73909ec
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri Jan 29 12:22:58 2010 +0000

    * Added an option "fsync-metadata" to fsync() changes to
      /nix/var/nix/db.
    * Removed the function writeStringToFile since it does (almost) the
      same thing as writeFile.

commit ad529fb89fb34bea9762eccfc9c2ee6f1f2865c0
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri Jan 29 11:53:58 2010 +0000

    * Don't consider a store path valid if its info file exists but is
      zero bytes long.  That makes Nix more robust in case of crashes
      (especially on ext4).

commit fdcaf37361126793a1416ef5b348e5bf2f0fd1a0
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Jan 25 17:18:44 2010 +0000

    * Made `nix-store -qR --include-outputs' much faster if there are
      multiple paths specified on the command line (from O(n * m) to O(n +
      m), where n is the number of arguments and m is the size of the
      closure).

commit 50e34891f0e11f400bd50390ede3b7700a2b4db9
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Jan 25 16:14:45 2010 +0000

    * Disable gzip compression in build-remote.pl because it puts too much
      load on the Hydra build farm (where it's unnecessary anyway because
      it has a fast connection to the build machines).  In any case,
      compression can be enabled by using the `-C' option to ssh.

commit 5388944e8d1ca61e23d42a6a0769b925f099f4e1
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Jan 25 16:04:32 2010 +0000

    * Make the garbage collector do the right thing when `gc-keep-outputs'
      is enabled by not depending on the deriver.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Jan 12 12:22:38 2010 +0000

    * On startup, set the default SIGCHLD handler.  This is so that Nix
      works correctly in weird environments where the SIGCHLD handler is
      set to "ignore".

commit ef92a14bfea7a16102b04711c9c18ad717e82ea1
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Thu Dec 17 14:12:44 2009 +0000

    * Include config.h before the C library headers, because it defines
      _FILE_OFFSET_BITS=64.  Without it, functions like stat() fail on
      large file sizes.  This happened with a Nix store on squashfs:

      $ nix-store --dump /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds > /dev/null
      error: getting attributes of path `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds': Value too large for defined data type

      $ stat /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds
      File: `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds'
      Size: 0               Blocks: 36028797018963968 IO Block: 1024   regular empty file

      (This is a bug in squashfs or mksquashfs, but it shouldn't cause Nix
      to fail.)

Date:   Tue Nov 24 10:51:52 2009 +0000

    * In the garbage collector, don't count files with a link count > 1 in
      the "bytes/blocks freed" statistics.

commit f9e766db9875e7ab390df8d405d9719b279efe3c
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Nov 24 09:53:18 2009 +0000

    * Randomise the order in which we delete entries to make the collector
      less biased towards deleting paths that come alphabetically first
      (e.g. /nix/store/000...).  This matters when using --max-freed etc.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Nov 23 18:16:25 2009 +0000

    * A command `nix-store --query --roots <paths>' to find the garbage
      collector roots that point (directly or indirectly) to the given
      paths.

commit ae6bf87273b30258408dc292611f3f50015b843c
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Nov 23 17:23:12 2009 +0000

    * `nix-store --gc --print-roots': also print the path of the actual
      root symlink, not just its target.  E.g.:

      /nix/var/nix/profiles/system-99-link -> /nix/store/76kwf88657nq7wgk1hx3l1z5q91zb9wd-system

commit c364d5d1e36a9f790b0d610aae1d30d8732b58ce
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Nov 23 16:34:24 2009 +0000

    * Made the garbage collector a lot faster.  It no longer computes the
      complete set of live and dead paths before starting the actual
      deletion, but determines liveness on demand.  I.e. for any path in
      the store, it first tries to delete all the referrers, and then the
      path itself.  This means that the collector can start deleting paths
      almost immediately.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Nov 23 12:48:54 2009 +0000

    * Don't create /nix/var/nix/gcroots/{tmp,channels}, since they don't
      seem to be used anymore.

commit 8824d60fe549e2fc9b5a852fc1b967eca241ea77
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri Nov 20 17:12:38 2009 +0000

    * Remove the --use-atime / --max-atime garbage collector flags.  Many
      (Linux) machines no longer maintain the atime because it's too
      expensive, and on the machines where --use-atime is useful (like the
      buildfarm), reading the atimes on the entire Nix store takes way too
      much time to make it practical.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Nov 17 16:22:39 2009 +0000

    * Don't pass -K.  It should really inherit the setting of the calling
      Nix though.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri Nov 13 10:08:31 2009 +0000

    * In nix-pull/nix-channel, create the manifests directory if it
      doesn't exist.  The Debian packages don't include the manifests
      directory, so nix-channel would silently skip doing a nix-pull,
      resulting in everything being built from source.  Thanks to Juan
      Pedro Bolívar Puente.

Date:   Thu Oct 22 08:28:33 2009 +0000

    * When building in a chroot, make a copy of a file if hard-linking
      fails.  This is likely to happen after a `nix-store --optimise',
      because some files may have 32000 links (NIX-111).

    * builtins.trace: in the common case that the value is a string, then
      show the string, not the ATerm, so we get `trace: bla' instead of
      `trace: Str("bla",[])'.

    configure.ac: use AC_SYS_LARGEFILE to determine how to enable 64-bit file size support

    Defining -D_FILE_OFFSET_BITS=64 works on most platforms, but not on all (i.e.
    Solaris). Also, the Autoconf macro offers the user a switch to disable the
    functionality in case of problems.

      giving jobs to the first machine until it hits its job limit, then
      the second machine and so on.  This should improve utilisation of
      the Hydra build farm a lot.  Also take an optional speed factor
      into account to cause fast machines to be preferred over slower
      machines with a similar load.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Sep 15 13:01:46 2009 +0000

    * Two primops: builtins.intersectAttrs and builtins.functionArgs.
      intersectAttrs returns the (right-biased) intersection between two
      attribute sets, e.g. every attribute from the second set that also
      exists in the first.  functionArgs returns the set of attributes
      expected by a function.

      The main goal of these is to allow the elimination of most of
      all-packages.nix.  Most package instantiations in all-packages.nix
      have this form:

        foo = import ./foo.nix {
          inherit a b c;
        };

      With intersectAttrs and functionArgs, this can be written as:

        foo = callPackage (import ./foo.nix) { };

      where

       callPackage = f: args:
         f ((builtins.intersectAttrs (builtins.functionArgs f) pkgs) // args);

      I.e., foo.nix is called with all attributes from "pkgs" that it
      actually needs (e.g., pkgs.a, pkgs.b and pkgs.c).  (callPackage can
      do any other generic package-level stuff we might want, such as
      applying makeOverridable.)  Of course, the automatically supplied
      arguments can be overriden if needed, e.g.

        foo = callPackage (import ./foo.nix) {
          c = c_version_2;
        };

      but for the vast majority of packages, this won't be needed.

      The advantages are to reduce the amount of typing needed to add a
      dependency (from three sites to two), and to reduce the number of
      trivial commits to all-packages.nix.  For the former, there have
      been two previous attempts:

        - Use "args: with args;" in the package's function definition.
          This however obscures the actual expected arguments of a
          function, which is very bad.

        - Use "{ arg1, arg2, ... }:" in the package's function definition
          (i.e. use the ellipis "..." to allow arbitrary additional
          arguments), and then call the function with all of "pkgs" as an
          argument.  But this inhibits error detection if you call it with
          an misspelled (or obsolete) argument.

    * Canonicalise timestamps in the Nix store to 1 (1970-01-01 00:00:01
      UTC) rather than 0 (00:00:00).  1 is a better choice because some
      programs use 0 as a special value.  For instance, the Template
      Toolkit uses a timestamp of 0 to denote the non-existence of a file,
      so it barfs on files in the Nix store (see
      template-toolkit-nix-store.patch in Nixpkgs).  Similarly, Maya 2008
      fails to load script directories with a timestamp of 0 and can't be
      patched because it's closed source.

      This will also shut up those "implausibly old time stamp" GNU tar
      warnings.

    * Change the scoping of "inherit (e) ..." in recs so that the
      attributes of the rec are in scope of `e'.  This is useful in
      expressions such as

        rec {
          lib = import ./lib;
          inherit (lib) concatStrings;
        }

      It does change the semantics of expressions such as

        let x = {y = 1;}; in rec { x = {y = 2;}; inherit (x) y; }.y

      This now returns 2 instead of 1.  However, no code in Nixpkgs or
      NixOS seems to rely on the old behaviour.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri May 15 12:35:23 2009 +0000

    * Some syntactic sugar for attribute sets: allow {x.y.z = ...;} as a
      shorthand for {x = {y = {z = ...;};};}.  This is especially useful
      for NixOS configuration files, e.g.

        {
          services = {
            sshd = {
              enable = true;
              port = 2022;
            };
          };
        }

      can now be written as

        {
          services.sshd.enable = true;
          services.sshd.port = 2022;
        }

      However, it is currently not permitted to write

        {
          services.sshd = {enable = true;};
          services.sshd.port = 2022;
        }

      as this is considered a duplicate definition of `services.sshd'.

    * Allow unsafe (unspecified) comparisons between attrsets unless
      NIX_NO_UNSAFE_EQ is set, for now.

commit c34e6d71bc62bb83f3bfed69f781ded4d5a46d3a
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon May 11 15:50:14 2009 +0000

    * Disallow equality tests between attribute sets.  This was always
      broken, but now the evaluator checks for it to prevent Nix
      expressions from relying on undefined behaviour.  Equality tests are
      implemented using a shallow pointer equality test between ATerms.
      However, because attribute sets are lazy and contain position
      information, this can give false positives.  For instance,
      previously

        let y = {x = 1;}; in y == y

      evaluated to true, while the equivalent expression

        {x = 1;} == {x = 1;}

      evaluated to false.  So disallow these tests for now.  (Eventually
      we may want to implement deep equality tests for attribute sets,
      like lib.eqStrict.)

    * Idem: disallow comparisons between functions.

    * Implemented deep comparisons of lists.  This had the same problem as
      attribute sets - the elements in the list weren't evaluated.  For
      instance,

        ["xy"] == [("x" + "y")]

      evaluated to false.  Now it works properly.

    * Fix a few "comparison is always false/true due to limited range of
      data type" warnings on 64-bit platforms.  The one in parser.y is
      likely to be a real bug.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Sun Mar 29 18:00:45 2009 +0000

    * Use polling to wait for a remote build slot when using a build hook
      (that is, call the build hook with a certain interval until it
      accepts the build).
    * build-remote.pl was totally broken: for all system types other than
      the local system type, it would send all builds to the *first*
      machine of the appropriate type.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Mar 25 16:43:38 2009 +0000

    * Removed the locking.sh test; it's redundant because of the extended

    * Shut up a GCC warning.

commit cacff1be886ed975bbef1b17151b25c633711256
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Mar 23 01:05:54 2009 +0000

    * No longer block while waiting for a lock on a store path.  Instead
      poll for it (i.e. if we can't acquire the lock, then let the main
      select() loop wait for at most a few seconds and then try again).
      This improves parallelism: if two nix-store processes are both
      trying to build a path at the same time, the second one shouldn't
      block; it should first see if it can build other goals.  Also, it
      prevents the deadlocks that have been occuring in Hydra lately,
      where a process waits for a lock held by another process that's
      waiting for a lock held by the first.

      The downside is that polling isn't really elegant, but POSIX doesn't
      provide a way to wait for locks in a select() loop.  The only
      solution would be to spawn a thread for each lock to do a blocking
      fcntl() and then signal the main thread, but that would require
      pthreads.

      (previously it would likely say "implementation cannot deal with >
      32-bit integers").

    * NAR archives: handle files larger than 2^32 bytes.  Previously it
      would just silently store only (fileSize % 2^32) bytes.
    * Use posix_fallocate if available when unpacking archives.
    * Provide a better error message when trying to unpack something that
      isn't a NAR archive.

    * Unify exportReferencesGraph and exportBuildReferencesGraph, and make
      sure that it works as expected when you pass it a derivation.  That
      is, we have to make sure that all build-time dependencies are built,
      and that they are all in the input closure (otherwise remote builds
      might fail, for example).  This is ensured at instantiation time by
      adding all derivations and their sources to inputDrvs and inputSrcs.

    * Acquire the locks on the output paths before trying to run the build

      completely filled with 0's because another nix-store process

    * download-using-manifests: don't check the cryptographic hash of
      downloaded files; rather, check the hash of the unpacked store
      path.

      When the server produces bzipped NAR archives on demand (like Hydra
      does), the hash of the file is not known in advance; it's streamed
      from the server.  Thus the manifest doesn't contain a hash for the
      bzipped NAR archive.  However, the server does know the hash of the
      *uncompressed* NAR archive (the "NarHash" field), since it's stored
      in the Nix database (nix-store -q --hash /nix/store/bla).  So we use
      that instead for checking the integrity of the download.

    * Release output locks as soon as possible, not when the destructor of
      the DerivationGoal runs.  Otherwise, if a goal is a top-level goal,
      then the lock won't be released until nix-store finishes.  With
      --keep-going and lots of top-level goals, it's possible to run out
      of file descriptors (this happened sometimes in the build farm for
      Nixpkgs).  Also, for failed derivation, it won't be possible to
      build it again  until the lock is released.

    * Idem for locks on build users: these weren't released in a timely
      manner for failed top-level derivation goals.  So if there were more
      than (say) 10 such failed builds, you would get an error about
      having run out of build users.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Feb 2 17:24:10 2009 +0000

    * Build hooks: use nix-store --import.  This prevents a redundant
      scan for runtime dependencies (i.e. the local machine shouldn't do a
      scan that the remote machine has already done).  Also pipe directly
      into `nix-store --import': don't use a temporary file.

    * When using a build hook, distinguish between transient failures
      (e.g. an SSH connection problem) and permanent failures (i.e. the
      builder failed).  This matters to Hydra (it wants to know whether it
      makes sense to retry a build).

    * We can't use string objects in signal handlers because they might
      allocate memory, which is verboten in signal handlers.  This caused
      random failures in the test suite on Mac OS X (triggered by the spurious

Date:   Thu Dec 11 18:57:10 2008 +0000

    * Don't provide the whole Nix store in the chroot, but only the
      closure of the inputs.  This really enforces that there can't be any
      undeclared dependencies on paths in the store.  This is done by
      creating a fake Nix store and creating bind-mounts or hard-links in
      the fake store for all paths in the closure.  After the build, the
      build output is moved from the fake store to the real store.  TODO:
      the chroot has to be on the same filesystem as the Nix store for
      this to work, but this isn't enforced yet.  (I.e. it only works
      currently if /tmp is on the same FS as /nix/store.)

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Thu Dec 11 17:00:12 2008 +0000

    * Do chroot builds in a private namespace.  This means that all the
      bind-mounts we do are only visible to the builder process and its
      children.  So accidentally doing "rm -rf" on the chroot directory
      won't wipe out /nix/store and other bind-mounted directories
      anymore.  Also, the bind-mounts in the private namespace disappear
      automatically when the builder exits.

    * Prefer building on a remote machine over a local machine.  This

Date:   Thu Dec 4 14:29:41 2008 +0000

    * When using build hooks, for any nix-store -r build operation, it is
      necessary that at least one build hook doesn't return "postpone",
      otherwise nix-store will barf ("waiting for a build slot, yet there
      are no running children").  So inform the build hook when this is
      the case, so that it can start a build even when that would exceed
      the maximum load on a machine.

    * Don't ignore errors from writing to stderr.  That way, when
      nix-store -r (or some other operation) is started via ssh, it will
      at least have a chance of terminating quickly when the connection is
      killed.  Right now it just runs to completion, because it never
      notices that stderr is no longer connected to anything.  Of course
      it would be better if sshd would just send a SIGHUP, but it doesn't
      (https://bugzilla.mindrot.org/show_bug.cgi?id=396).

        root@example.org i686-darwin  /root/.ssh/id_buildfarm 1

      This is possible when the Nix installation on example.org itself has
      remote builds enabled.

    * Dirty hack to make nix-push work properly on derivations: the
      derivation should be a source rather than a derivation dependency of
      the call to the NAR derivation.  Otherwise the derivation (and all

      succeed.

commit 64519cfd657d024ae6e2bb74cb21ad21b886fd2a
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Dec 3 15:06:30 2008 +0000

    * Unify the treatment of sources copied to the store, and recursive
      SHA-256 outputs of fixed-output derivations.  I.e. they now produce
      the same store path:

      $ nix-store --add x
      /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x

      $ nix-store --add-fixed --recursive sha256 x
      /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x

      the latter being the same as the path that a derivation

        derivation {
          name = "x";
          outputHashAlgo = "sha256";
          outputHashMode = "recursive";
          outputHash = "...";
          ...
        };

      produces.

      This does change the output path for such fixed-output derivations.
      Fortunately they are quite rare.  The most common use is fetchsvn
      calls with SHA-256 hashes.  (There are a handful of those is
      Nixpkgs, mostly unstable development packages.)

    * Documented the computation of store paths (in store-api.cc).

      the tests) is a bad idea when $bindir = /usr and some programs (like
      perl) live there.  Fortunately it doesn't seem to be needed anymore.

      explicitly overriden.

    * Primop builtins.storePath for declaring a store path as a
      dependency.  `storePath /nix/store/bla' gives exactly the same
      result as `toPath /nix/store/bla', except that the former includes
      /nix/store/bla in the dependency context of the string.

      Useful in some generated Nix expressions like nix-push, which now
      finally does the right thing wrt distributed builds.  (Previously
      the path to be packed wasn't an explicit dependency, so it wouldn't
      be copied to the remote machine.)

      subtle and often hard-to-reproduce bugs where programs in pipes
      either barf with a "Broken pipe" message or not, depending on the
      exact timing conditions.  This particularly happened in GNU M4 (and
      Bison, which uses M4).

    * GC option `--max-atime' that specifies an upper limit to the last
      accessed time of paths that may be deleted.  Anything more recently
      used won't be deleted.  The time is specified in time_t,
      e.g. seconds since 1970-01-01 00:00:00 UTC; use `date +%s' to
      convert to time_t from the command line.

      Example: to delete everything that hasn't been used in the last two
      months:

      $ nix-store --gc -v --max-atime $(date +%s -d "2 months ago")

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Sep 17 10:02:55 2008 +0000

    * Garbage collector: added an option `--use-atime' to delete paths in
      order of ascending last access time.  This is useful in conjunction
      with --max-freed or --max-links to prefer deleting non-recently used
      garbage, which is good (especially in the build farm) since garbage
      may become live again.

      The code could easily be modified to accept other criteria for
      ordering garbage by changing the comparison operator used by the
      priority queue in collectGarbage().

    * When writing the user environment manifest, filter out non-string
      attributes from the meta attribute.  Not doing so caused nix-env to
      barf on the "psi" package, which has a meta.function attribute,
      the textual serialisation of which causes a gigantic string to be
      produced --- so big that it causes nix-env to run out of memory.

      Note however that "meta" really only should contain strings.
      meta.function should be passthru.function.

    * Require that __overrides is defined as a non-recursive attribute

      scoping bugs, since __overrides can't be recursive (or at least, it
      would be hard).

    * Disable chroot builds for fixed-output derivations so that we don't
      need /etc in the chroot (in particular, /etc/resolv.conf for
      fetchurl).  Not having /etc/resolv.conf in the chroot is a good
      thing, since we don't want normal derivations to download files.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Thu Aug 14 16:59:37 2008 +0000

    * Another experimental feature: a way to truly override attributes in
      a rec.  This will be very useful to allow end-user customisation of
      all-packages.nix, for instance globally overriding GCC or some other
      dependency.  The // operator doesn't cut it: you could replace the
      "gcc" attribute, but all other attributes would continue to
      reference the original value due to the substitution semantics of
      rec.

      The syntax is a bit hacky but this is to allow backwards
      compatibility.

commit 9279174dde3e1a450e63e866d2683352dd8238d3
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Thu Aug 14 14:00:44 2008 +0000

    * Added an experimental feature suggested by Andres: ellipses ("...")
      in attribute set pattern matches.  This allows defining a function
      that takes *at least* the listed attributes, while ignoring
      additional attributes.  For instance,

        {stdenv, fetchurl, fuse, ...}:

        stdenv.mkDerivation {
          ...
        };

      defines a function that requires an attribute set that contains the
      specified attributes but ignores others.  The main advantage is that
      we can then write in all-packages.nix

        aefs = import ../bla/aefs pkgs;

      instead of

        aefs = import ../bla/aefs {
          inherit stdenv fetchurl fuse;
        };

      This saves a lot of typing (not to mention not having to update
      all-packages.nix with purely mechanical changes).  It saves as much
      typing as the "args: with args;" style, but has the advantage that
      the function arguments are properly declared (not implicit in what
      the body of the "with" uses).

      pattern-matched against the attribute set pattern {x, y, z}.

    * Refactoring: combine functions that take an attribute set and
      functions that take a single argument (plain lambdas) into one AST
      node (Function) that contains a Pattern node describing the
      arguments.  Current patterns are single lazy arguments (VarPat) and
      matching against an attribute set (AttrsPat).

      This refactoring allows other kinds of patterns to be added easily,
      such as Haskell-style @-patterns, or list pattern matching.

    Updates to nix-reduce-build

    Common code in local build package sources refactored out in a function; before building the real set of derivations needed is found (slightly slower for only one build strategy, but less garbage on output and better performance for multiple build strategies).

    Now you have full choice of best-effort build regardless of method (substituters or actual build), using substituters, building only fixed derivations (should get you all the downloads) and local build without even trying substituters.

    Some minor fix in the help text about behavior with no package sources.

    * Use optimistic profile locking for nix-env operations like `-i' and
      `-u'.  Instead of acquiring an exclusive lock on the profile for the
      entire duration of the operation, we just perform the operation
      optimistically (without an exclusive lock), and check at the end
      whether the profile changed while we were busy (i.e., the symlink
      target changed).  If so, the operation is restarted.  Restarting is
      generally cheap, since the build results are still in the Nix store.
      Most of the time, only the user environment has to be rebuilt.

    * Make nix-env --dry-run print the paths to be substituted correctly
      again.  (After the previous substituter mechanism refactoring I
      didn't update the code that obtains the references of substitutable
      paths.)  This required some refactoring: the substituter programs
      are now kept running and receive/respond to info requests via
      stdin/stdout.

    * Use the copy-from-other-stores substituter by default.  Of course,
      it only does something if $NIX_OTHER_STORES (not really a good
      name...) is set.
    * Do globbing on the elements of $NIX_OTHER_STORES.  E.g. you could
      set it to /mnts/*/nix or something.
    * Install substituters in libexec/nix/substituters.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Sat Jul 12 18:58:24 2008 +0000

    * Quick prototype of a substituter that copies paths from other Nix
      stores (typically remote Nix stores mounted via e.g. NFS, or the Nix
      store on the NixOS installation CD).  Example use:

      $ sshfs foo@example.org:/ /mnt
      $ NIX_OTHER_STORES=/mnt/nix \
        NIX_SUBSTITUTERS=.../copy-from-other-stores.pl \
        nix-env -i foo

      This will be especially useful for the installation CD since it
      doesn't require a manifest for the CD contents.

    * Export the nix-env derivation name parsing and version comparison
      logic through the `parseDrvName' and `compareVersions' primops.
      This will allow expressions to easily check whether some dependency
      is a specific needed version or falls in some version range.  See
      tests/lang/eval-okay-versions.nix for examples.

      for very large Nix stores on filesystems with a 32000 subdirectories

    * checkVarDefs: don't check in closed terms, which don't have
      undefined variables by definition.  This matters for the
      implementation of "with", which does a call to checkVarDefs to see
      if the body of the with has no undefined variables.  (It can't be
      checked at parse time because you don't know which variables are in
      the "with" attribute set.)  If we check closed terms, then we check
      not just the with body but also the substituted terms, which are
      typically very large.  This is the cause of the poor nix-env
      performance on Nixpkgs lately.  It didn't happen earlier because
      "with" wasn't used very often in the past.

      This fix improves nix-env performance roughly 60x on current Nixpkgs.
      nix-env -qa is down from 29.3s to 0.5s on my laptop, and nix-env -qa
      --out-path is down from 229s to 3.39s.  Not bad for a 1-line fix :-)

      where the antiquote should work as expected, instead of giving the
      string "'${foo}'".

commit 6d6c68c0d29310b6eca35f58b1e68f495d6cd33a
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri Nov 30 16:48:45 2007 +0000

    * Added a new kind of multi-line string literal delimited by two
      single quotes.  Example (from NixOS):

        job = ''
          start on network-interfaces

          start script

            rm -f /var/run/opengl-driver
            ${if videoDriver == "nvidia"
              then "ln -sf ${nvidiaDrivers} /var/run/opengl-driver"
              else if cfg.driSupport
              then "ln -sf ${mesa} /var/run/opengl-driver"
              else ""
            }

            rm -f /var/log/slim.log

          end script
        '';

      This style has two big advantages:

      - \, ' and " aren't special, only '' and ${.  So you get a lot less
        escaping in shell scripts / configuration files in Nixpkgs/NixOS.
        The delimiter '' is rare in scripts (and can usually be written as
        "").  ${ is also fairly rare.

        Other delimiters such as <<...>>, {{...}} and <|...|> were also
        considered but this one appears to have the fewest drawbacks
        (thanks Martin).

      - Indentation is intelligently stripped so that multi-line strings
        can follow the nesting structure of the containing Nix
        expression.  E.g. in the example above 6 spaces are stripped from
        the start of each line.  This prevents unnecessary indentation in
        generated files (which sometimes even breaks things).

      See tests/lang/eval-okay-ind-string.nix for some examples.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Thu Nov 29 16:18:24 2007 +0000

    * nix-env -e: support uninstalling by path, so that one can say

        $ nix-env -e $(which firefox)

      or

        $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132

    * nix-env -i: if an argument contains a slash anywhere, treat it as a
      path and follow it through symlinks into the Nix store.  This allows
      things like

        $ nix-build -A firefox
        $ nix-env -i ./result

    * nix-env -q/-i/-e: don't complain when the `*' selector doesn't match
      anything.  In particular, `nix-env -q \*' doesn't fail anymore on an
      empty profile.

commit 9397cd30c8a6ffd65fc3b85985ea59ecfb72672b
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Sat Oct 27 00:46:59 2007 +0000

    * Support for doing builds in a chroot under Linux.  The builder is
      executed in a chroot that contains just the Nix store, the temporary
      build directory, and a configurable set of additional directories
      (/dev and /proc by default).  This allows a bit more purity
      enforcement: hidden build-time dependencies on directories such as
      /usr or /nix/var/nix/profiles are no longer possible.  As an added
      benefit, accidental network downloads (cf. NIXPKGS-52) are prevented
      as well (because files such as /etc/resolv.conf are not available in
      the chroot).

      However the usefulness of chroots is diminished by the fact that
      many builders depend on /bin/sh, so you need /bin in the list of
      additional directories.  (And then on non-NixOS you need /lib as
      well...)

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Oct 9 22:14:27 2007 +0000

    * New command `nix-store --optimise' to reduce Nix store disk space
      usage by finding identical files in the store and hard-linking them
      to each other.  It typically reduces the size of the store by
      something like 25-35%.  This is what the optimise-store.pl script
      did, but the new command is faster and more correct (it's safe wrt
      garbage collection and concurrent builds).

    * listToAttrs: the list now should consist of {name, value} attribute

    * nix-env -qa: make the "-A" flag do the expected thing, namely follow
      the given attribute path (just as -A does with other option)
      (NIX-83).  So you can now say

      $ nix-env -qa -A nixpkgs_unstable.gnome \*
      atk-1.12.4
      esound-0.2.36
      ...

      to see the packages in the "gnome" attribute in Nixpkgs.

      To *print* the attribute path, you should now use "--attr-path" /
      "-P" (running out of letters...).

    * nix-env: allow ~/.nix-defexpr to be a directory.  If it is, then the
      Nix expressions in that directory are combined into an attribute set
      {file1 = import file1; file2 = import file2; ...}, i.e. each Nix
      expression is an attribute with the file name as the attribute
      name.  Also recurses into directories.

    * nix-env: removed the "--import" (-I) option which set the
      ~/.nix-defexpr symlink.

    * nix-channel: don't use "nix-env --import", instead symlink
      ~/.nix-defexpr/channels.  So finally nix-channel --update doesn't
      override any default Nix expressions but combines with them.

      This means that you can have (say) a local Nixpkgs SVN tree and use
      it as a default for nix-env:

      $ ln -s .../path-to-nixpkgs-tree ~/.nix-defexpr/nixpkgs_svn

      and be subscribed to channels (including Nixpkgs) at the same time.
      (If there is any ambiguity, the -A flag can be used to
      disambiguate, e.g. "nix-env -i -A nixpkgs_svn.pan".)

    * Create the Nix daemon socket in a separate directory
      (/nix/var/nix/daemon-socket).  This allows access to the Nix daemon
      to be restricted by setting the mode/ownership on that directory as
      desired, e.g.

        $ chmod 770 /nix/var/nix/daemon-socket
        $ chown root.wheel /nix/var/nix/daemon-socket

      to allow only users in the wheel group to use Nix.

      Setting the ownership on a socket is much trickier, since the socket
      must be deleted and recreated every time the daemon is started
      (which would require additional Nix configuration file directives to
      specify the mode/ownership, and wouldn't support arbitrary ACLs),
      some BSD variants appear to ignore permissions on sockets, and it's
      not clear whether the umask is respected on every platform when
      creating sockets.

    * When there are multiple substituters, make sure to release the
      lock on the output path after trying each.  Otherwise the
      pathIsLockedByMe() test gets confused.

commit c970b28ba0f8866bde800849120d429d781ccb5d
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Aug 28 11:36:17 2007 +0000

    * Fix a race condition with parallel builds where multiple
      fixed-output derivations or substitutions try to build the same
      store path at the same time.  Locking generally catches this, but
      not between multiple goals in the same process.  This happened
      especially often (actually, only) in the build farm with fetchurl
      downloads of the same file being executed on multiple machines and
      then copied back to the main machine where they would clobber each
      other (NIXBF-13).

      Solution: if a goal notices that the output path is already locked,
      then go to sleep until another goal finishes (hopefully the one
      locking the path) and try again.

      executed in parallel and then copied back to the main machine.

      permission.)

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Sun Aug 12 00:29:28 2007 +0000

    * Get rid of the substitutes database table (NIX-47).  Instead, if we
      need any info on substitutable paths, we just call the substituters
      (such as download-using-manifests.pl) directly.  This means that
      it's no longer necessary for nix-pull to register substitutes or for
      nix-channel to clear them, which makes those operations much faster
      (NIX-95).  Also, we don't have to worry about keeping nix-pull
      manifests (in /nix/var/nix/manifests) and the database in sync with
      each other.

      The downside is that there is some overhead in calling an external
      program to get the substitutes info.  For instance, "nix-env -qas"
      takes a bit longer.

      Abolishing the substitutes table also makes the logic in
      local-store.cc simpler, as we don't need to store info for invalid
      paths.  On the downside, you cannot do things like "nix-store -qR"
      on a substitutable but invalid path (but nobody did that anyway).

    * Never catch interrupts (the Interrupted exception).

      still in the Nix store.

    * Give unpacked channels more sensible names than 0, 1, ...  They now
      get the basename of the channel URL (e.g., nixpkgs-unstable).  The
      top-level Nix expression of the channel is now an attribute set, the
      attributes of which are the individual channels (e.g.,
      {nixpkgs_unstable = ...; strategoxt_unstable = ...}).  This makes
      attribute paths ("nix-env -qaA" and "nix-env -iA") more sensible,
      e.g., "nix-env -iA nixpkgs_unstable.subversion".

    * nix-env -i: instead of breaking package ties by version, break them
      by priority and version install.  That is, if there are multiple
      packages with the same name, then pick the package with the highest
      priority, and only use the version if there are multiple packages
      with the same priority.

      This makes it possible to mark specific versions/variant in Nixpkgs
      more or less desirable than others.  A typical example would be a
      beta version of some package (e.g., "gcc-4.2.0rc1") which should not
      be installed even though it is the highest version, except when it
      is explicitly selected (e.g., "nix-env -i gcc-4.2.0rc1").

    * Idem for nix-env -u, only the semantics are a bit trickier since we
      also need to take into account the priority of the currently
      installed package (we never upgrade to a lower priority, unless
      --always is given).

    * Package flag "keep" that prevents a package from being removed from
      a user environment by an install or upgrade action.  This is
      particularly useful if you have a version installed that you don't
      want to upgrade (e.g., because the newer versions are broken).
      Example:

        $ nix-env -u zapping --dry-run

        upgrading `zapping-0.9.6' to `zapping-0.10cvs6'

        $ nix-env --set-flag keep true zapping

        $ nix-env -u zapping --dry-run
        (dry run; not doing anything)

      However, "-e" will still uninstall the package.  (Maybe we should
      require the keep flag to be explicitly set to false before it can be
      uninstalled.)

    * Package conflict resolution through priority levels.  If there is a
      user environment collission between two packages due to overlapping
      file names, then a package with a higher priority will overwrite the
      symlinks of a package with a lower priority.  E.g.,

        $ nix-env --set-flag priority 5 gcc
        $ nix-env --set-flag priority 10 binutils

      gives gcc a higher priority than binutils (higher number = lower
      priority).

    * Allow conflicting packages to be kept in a user environment, and
      allow switching between them (NIX-80).

      Example: two versions of Pan:

        $ nix-env -q pan
        pan-0.128
        pan-0.14.2.91

        $ readlink $(which pan)
        /nix/store/l38jrbilw269drpjkx7kinhrxj6fjh59-pan-0.14.2.91/bin/pan

      At most one of them can be active any given time.  Assuming than
      0.14.2.91 is active, you can active 0.128 as follows:

        $ nix-env --set-flag active false pan-0.14.2.91
        $ nix-env --set-flag active true pan-0.128

        $ readlink $(which pan)
        /nix/store/nziqwnlzy7xl385kglxhg75pfl5i936n-pan-0.128/bin/pan

      More flags to follow.

    * nix-env -q now has a flag --prebuilt-only (-b<) that causes nix-env
      to show only those derivations whose output is already in the Nix
      store or that can be substituted (i.e., downloaded from somewhere).
      In other words, it shows the packages that can be installed “quickly”,
      i.e., don’t need to be built from source.

    * Greatly reduced the amount of stack space used by the Nix expression
      evaluator.  This was important because the NixOS expressions started
      to hit 2 MB default stack size on Linux.

      GCC is really dumb about stack space: it just adds up all the local
      variables and temporaries of every scope into one huge stack frame.
      This is really bad for deeply recursive functions.  For instance,
      every `throw Error(format("error message"))' causes a format object
      of a few hundred bytes to be allocated on the stack.  As a result,
      every recursive call to evalExpr2() consumed 4680 bytes.  By
      splitting evalExpr2() and by moving the exception-throwing code out
      of the main functions, evalExpr2() now only consumes 40 bytes.
      Similar for evalExpr().

      copies the closure of Subversion to machine `xyzzy'.  This is like
      `nix-pack-closure $(which svn) | ssh xyzzy', but it's much more
      efficient since it only copies those paths that are missing on the
      target machine.

    * nix-env now maintains meta info (from the `meta' derivation
      attribute) about installed packages in user environments.  Thus, an
      operation like `nix-env -q --description' shows useful information
      not only on available packages but also on installed packages.

    * nix-env now passes the entire manifest as an argument to the Nix
      expression of the user environment builder (not just a list of
      paths), so that in particular the user environment builder has
      access to the meta attributes.

    * New operation `--set-flag' in nix-env to change meta info of
      installed packages.  This will be useful to pass per-package
      policies to the user environment builder (e.g., how to resolve
      collision or whether to disable a package (NIX-80)) or upgrade
      policies in nix-env (e.g., that a package should be "masked", that
      is, left untouched by upgrade actions).  Example:

      $ nix-env --set-flag enabled false ghc-6.4

      outputs (unless they use builtins.toFile).

    * Nasty: Glibc clears the TMPDIR environment variable in setuid
      programs, so if a builder uses TMPDIR, then it will fail when
      executed through nix-setuid-helper.  In fact Glibc clears a whole
      bunch of variables (see sysdeps/generic/unsecvars.h in the Glibc
      sources), but only TMPDIR should matter in practice.  As a
      workaround, we reinitialise TMPDIR from NIX_BUILD_TOP.

    * `nix-store --verify': revive checking the referrers table.  This is
      important to get garbage collection to work if there is any
      inconsistency in the database (because the referrer table is used to
      determine whether it is safe to delete a path).

Date:   Tue Dec 12 23:05:01 2006 +0000

    * New primop builtins.filterSource, which can be used to filter files
      from a source directory.  All files for which a predicate function
      returns true are copied to the store.  Typical example is to leave
      out the .svn directory:

        stdenv.mkDerivation {
          ...
          src = builtins.filterSource
            (path: baseNameOf (toString path) != ".svn")
            ./source-dir;
          # as opposed to
          #   src = ./source-dir;
        }

      This is important because the .svn directory influences the hash in
      a rather unpredictable and variable way.

Date:   Tue Dec 12 19:06:02 2006 +0000

    * New operation `nix-env --set' which sets a user environment to a
      single derivation specified by the argument.  This is useful when we
      want to have a profile for a single derivation, such as a server
      configuration.  Then we can just say (e.g.)

      $ nix-env -p /.../server-profile -f server.nix --set -A server

      We can't do queries or upgrades on such a profile, but we can do
      rollbacks.  The advantage over -i is that we don't have to worry
      about other packages having been installed in the profile
      previously; --set gets rid of them.

    * Use lchown() instead of chown() in canonicalisePathMetaData().  This
      matters when running as root, since then we don't use the setuid
      helper (which already used lchown()).

    * Also check for an obscure security problem on platforms that don't
      have lchown.  Then we can't change the ownership of symlinks, which
      doesn't matter *except* when the containing directory is writable by
      the owner (which is the case with the top-level Nix store directory).

    * Kill a build if it has gone for more than a certain number of
      seconds without producing output on stdout or stderr (NIX-65).  This
      timeout can be specified using the `--max-silent-time' option or the
      `build-max-silent-time' configuration setting.  The default is
      infinity (0).

    * Fix a tricky race condition: if we kill the build user before the
      child has done its setuid() to the build user uid, then it won't be
      killed, and we'll potentially lock up in pid.wait().  So also send a
      conventional kill to the child.

    * Start of the setuid helper (the program that performs the operations
      that have to be done as root: running builders under different uids,
      changing ownership of build results, and deleting paths in the store
      with the wrong ownership).

      appears not to interrupt fcntl(..., F_SETLKW, ...), which is bad.

    * Some hardcore magic to handle asynchronous client disconnects.
      The problem is that when we kill the client while the worker is
      building, and the builder is not writing anything to stderr, then
      the worker never notice that the socket is closed on the other side,
      so it just continues indefinitely.  The solution is to catch SIGIO,
      which is sent when the far side of the socket closes, and simulate
      an normal interruption.  Of course, SIGIO is also sent every time
      the client sends data over the socket, so we only enable the signal
      handler when we're not expecting any data...

    * When NIX_REMOTE is set to "slave", fork off nix-worker in slave
      mode.  Presumably nix-worker would be setuid to the Nix store user.
      The worker performs all operations on the Nix store and database, so
      the caller can be completely unprivileged.

      This is already much more secure than the old setuid scheme, since
      the worker doesn't need to do Nix expression evaluation and so on.
      Most importantly, this means that it doesn't need to access any user
      files, with all resulting security risks; it only performs pure
      store operations.

      Once this works, it is easy to move to a daemon model that forks off
      a worker for connections established through a Unix domain socket.
      That would be even more secure.

      implementation is LocalStore, which operates on the Nix store
      directly.  The next step, to enable secure multi-user Nix, is to
      create a different implementation RemoteStore that talks to a
      privileged daemon process that uses LocalStore to perform the actual
      operations.

    * Turn off synchronisation between C and C++ I/O functions.  This
      gives a huge speedup in operations that read or write from standard
      input/output.  (So libstdc++'s I/O isn't that bad, you just have to
      call std::ios::sync_with_stdio(false).)  For instance, `nix-store
      --register-substitutes' went from 1.4 seconds to 0.1 seconds on a
      certain input.  Another victory for Valgrind.

commit e2a70b7ec04db604e9eaadfa6446bd360473163a
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Nov 13 18:18:13 2006 +0000

    * Magic attribute `exportReferencesGraph' that allows the references
      graph to be passed to a builder.  This attribute should be a list of
      pairs [name1 path1 name2 path2 ...].  The references graph of each
      `pathN' will be stored in a text file `nameN' in the temporary build
      directory.  The text files have the format used by `nix-store
      --register-validity'.  However, the deriver fields are left empty.

      `exportReferencesGraph' is useful for builders that want to do
      something with the closure of a store path.  Examples: the builders
      that make initrds and ISO images for NixOS.

      `exportReferencesGraph' is entirely pure.  It's necessary because
      otherwise the only way for a builder to get this information would
      be to call `nix-store' directly, which is not allowed (though
      unfortunately possible).

    * Option `--reregister' in `nix-store --register-validity'.  We need
      this in the NixOS installer (or in the buildfarm) to ensure that the
      cryptographic hash of the path contents still matches the actual
      contents.

commit 6a67556f7192108d612560992e97a14b0fe16a22
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Thu Oct 19 16:09:24 2006 +0000

    * Special derivation attribute `allowedReferences' that causes Nix to
      check that the references of the output of a derivation are in the
      specified set.  For instance,

        allowedReferences = [];

      specifies that the output cannot have any references.  (This is
      useful, for instance, for the generation of bootstrap binaries for
      stdenv-linux, which must not have any references for purity).  It
      could also be used to guard against undesired runtime dependencies,
      e.g.,

        {gcc, dynlib}: derivation {
          ...
          allowedReferences = [dynlib];
        }

      says that the output can refer to the path of `dynlib' but not
      `gcc'.  A `forbiddedReferences' attribute would be more useful for
      this, though.

commit d7efd7639420f4c840cbfdfcbbb3c45292f3ac54
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Oct 16 15:55:34 2006 +0000

    * Big cleanup of the semantics of paths, strings, contexts, string
      concatenation and string coercion.  This was a big mess (see
      e.g. NIX-67).  Contexts are now folded into strings, so that they
      don't cause evaluation errors when they're not expected.  The
      semantics of paths has been clarified (see nixexpr-ast.def).
      toString() and coerceToString() have been merged.

      Semantic change: paths are now copied to the store when they're in a
      concatenation (and in most other situations - that's the
      formalisation of the meaning of a path).  So

        "foo " + ./bla

      evaluates to "foo /nix/store/hash...-bla", not "foo
      /path/to/current-dir/bla".  This prevents accidental impurities, and
      is more consistent with the treatment of derivation outputs, e.g.,
      `"foo " + bla' where `bla' is a derivation.  (Here `bla' would be
      replaced by the output path of `bla'.)

    * Propagated packages now have lower priority; they are symlinked
      *after* the packages that have been explicitly installed, and
      collisions are ignored.

    * Quick hack to let nix-install-package set the package name properly
      (e.g., "java-front-0.9pre15899" instead of "java-front";
      particularly important when doing upgrades later on).

    * In `nix-channel --update', skip manifests that assume a Nix store at
      a different location than the user's.  This makes channels usable as
      a source deployment mechanism for people who install Nix under
      non-standard prefixes.  (NIX-57)

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri Sep 22 14:55:19 2006 +0000

    * Added a builtin function `isList' to test whether a value is a list.
      With this primitive, a list-flattening function can be implemented
      (NIX-55, example is in tests/lang/eval-okay-flatten.nix).

    * Builtin functions `head' and `tail' to return the head and tail of
      list.  Useful for lots of things, such as implementing a fold
      function (see NIX-30, example is in tests/lang/eval-okay-list.nix).

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri Sep 22 14:31:55 2006 +0000

    * New builtin functions builtins.{hasAttr, getAttr} to check for
      attribute existence and to return an attribute from an attribute
      set, respectively.  Example: `hasAttr "foo" {foo = 1;}'.  They
      differ from the `?' and `.' operators in that the attribute name is
      an arbitrary expression.  (NIX-61)

    * `show-duplication.pl', a small utility that shows the amount of
      package duplication present in (e.g.) a profile.  It shows the
      number of instances of each package in a closure, along with the
      size in bytes of each instance as well as the "waste" (the
      difference between the sum of the sizes of all instances and the
      average size).

      $ ./show-duplication.pl /nix/var/nix/profiles/default
      gcc 11
        3.3.6 19293318
        3.4.4 21425257

      This utility is useful for measuring the cost in terms of disk space
      of the Nix approach.

    * nix-env --switch-generation / --list-generations /

      unlikely) race conditions.

Date:   Thu Sep 14 22:30:33 2006 +0000

    * Fix a huge gaping hole in nix-env w.r.t. the garbage collector.
      Nix-env failed to call addPermRoot(), which is necessary to safely
      add a new root.  So if nix-env started after and finished before the
      garbage collector, the user environment (plus all other new stuff)
      it built might be garbage collected, leading to a dangling symlink
      chain in ~/.nix-profile...

    * Be more explicit if we block on the GC lock ("waiting for the big
      garbage collector lock...").

    * Don't loop trying to create a new generation.  It's not necessary
      anymore since profiles are locked nowadays.

commit 2e210b2387904ada0417ad5a7502e4e40b852e02
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Sep 6 14:23:04 2006 +0000

    * Convenience option `nix-collect-garbage -d' (--delete-old): removes
      old generations of *all* profiles in /nix/var/nix/profiles, then
      runs the garbage collector.  Quick way to get rid of all old stuff.
      Of course, one cannot roll back to earlier points in time after
      this.

    * Compile the lexer as C++ code.  Remove all the redundant C/C++
      marshalling code.

    * Store the Nix libraries in ${libdir}/nix instead of ${libdir}.

commit 7974aae81ced67b2aee0b537a37d813f6c67a1ec
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri Sep 1 12:07:31 2006 +0000

    * New primop: builtins.toFile, which writes a string into the store
      and returns its path.  This can be used to (for instance) write
      builders inside a Nix expression, e.g.,

      stdenv.mkDerivation {
        builder = "
          source $stdenv/setup
          ...
        ";
        ...
      }

Date:   Fri Sep 1 12:04:06 2006 +0000

    * Allow "$" in strings as long as they are not followed by "{".  (Too
      bad flex doesn't have lexical restrictions, the current solution
      isn't quite right...)

    * TDD: == should do a deep equality test, i.e., it should strictly
      evaluate its arguments.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Aug 28 21:47:42 2006 +0000

    * In toString, deal with nested lists properly (i.e., flatten them).

commit 1fca76870b7a96d1eb33abb8ad4e4cc5ba656253
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Aug 28 13:31:06 2006 +0000

    * Removed processBinding, instead we now apply toString to all
      derivation attributes to flatten them into strings.  This is
      possible since string can nowadays be wrapped in contexts that
      describe the derivations/sources referenced by the evaluation of the
      string.

    * New primop __toXML (or builtins.toXML) to convert an expression to
      an XML representation stored in a string.  This should be useful to
      pass structured information to builders.

    * Allow --arg in nix-env as well, example:

      $ nix-env -qa --system-filter \* --arg system '"powerpc-darwin"'

      to override the system from the default value (__currentSystem in
      all-packages.nix).

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Aug 23 16:20:14 2006 +0000

    * Pass the autoArgs to findAlongAttrPath so that "nix-instantiate
      foo.nix -A attr --arg name value" will work if (name, value) is
      needed in the evaluation leading up to "attr".

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Aug 23 14:39:11 2006 +0000

    * A new primop `builtins', which returns an attribute set containing
      all the primops.  This allows Nix expressions to test for new
      primops and take appropriate action if they're not available.  For
      instance, rather than calling a primop `foo' directly, they could
      say `if builtins ? foo then builtins.foo ... else ...'.

    * More XML output.  `--strict' to strictly evaluate attribute sets and
      so on.

    On cygwin, disable the check that the output is not group or world
    writable. File permissions on Cygwin are rather complex, and in this
    case this check introduced a problem with build jobs invoke from
    outside of Cygwin (MSYS). It seemed almost impossible to fix the
    permissions of the directory, so for now this safety check is disabled
    on Cygwin.

    * Applied rbroek's patch from the branch at
      https://svn.cs.uu.nl:12443/repos/trace/buildfarm-control/trunk/ext/nix/,
      with some modifications.  This allows `nix-env -qa' to show the
      attribute path that can be used to unambiguously install a package
      using `nix-env -i -A'.  Example:

        $ nix-env -f top-level/all-packages.nix -qaA subversion xorg-server
        subversionWithJava  subversion-1.2.3
        subversion          subversion-1.3.2
        subversion14        subversion-1.4.0pre-rc1
        xorg.xorgserver     xorg-server-1.1.0

commit 5744dd548039b9a8666a414dcb66629322e5af21
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Jul 25 11:53:22 2006 +0000

    * Support the --attr / -A flag in nix-env as well.  So now we can do,
      e.g.,

      $ nix-env -i -A subversion xorg.xorgserver

      The main advantage over using symbolic names is that using attribute
      names is unambiguous and much, much faster.

    * When there is a domain check, we have to evaluate the argument.
      Can't be lazy!

commit f4c5531d928caadee75d66bba40994f55f839be7
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Jul 24 16:35:34 2006 +0000

    * New language feature: domain checks, which check whether a function
      argument has a valid value, i.e., is in a certain domain.  E.g.,

        { foo : [true false]
        , bar : ["a" "b" "c"]
        }: ...

      This previously could be done using assertions, but domain checks
      will allow the buildfarm to automatically extract the configuration
      space from functions.

    * Call find-runtime-roots.pl from the garbage collector to prevent
      running applications etc. from being garbage collected.

commit ebcccbd3581d34d7fefb975c0255a39a3e39e122
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Jul 19 16:49:59 2006 +0000

    * Added a tool to find additional roots for the garbage collector,
      such as open files, current directories, mmaped files, etc.  This is
      inherently unportable, but it's easy to adapt this script to other
      platforms.  Currently we call `lsof' and try to read various bits in
      /proc/NNN.

      The goal is to prevent the garbage collector from removing store
      paths that are no longer reachable from a permanent root but that
      are still in use (for instance, after the user has done "nix-env -e"
      on a running program).

    * On Windows we cannot delete open (lock) files, so we delete lock
      files after we've closed them.  Since this only succeeds if the lock

      not necessary.

    * Started hacking on a ATermTable replacement, since ATermTable uses
      gigantic amounts of memory --- 65536 bytes per table at least ---
      which makes it unsuitable for representing short-lived substitution
      tables and attribute sets.

      identifiers.

    * Escaping in string literals: \n, \r, \t interpreted as in C, any
      other character following \ is interpreted as-is.

    * Newlines are now allowed in string literals.

    * `nix-env -q' now accepts arguments that allow specific derivations
      to be queried, e.g., `nix-env -qa firefox'.  This does require the

      derivations, so the old `nix-env -qa' now is `nix-env -qa "*"'.

    * Big speedup (factor > 2.5) in all nix-env operations that do actual
      instantiation, e.g. "nix-env -i" and "nix-env -qas" (but not
      "nix-env -qa").  It turns out that many redundant calls to
      addToStore(path) were made, which reads and hashes the entire path.
      For instance, the bash bootstrap binary in Nixpkgs would be read and
      hashed many times.  As a result nix-env would spend around 92% of
      its time in the function sha256_block (according to callgrind).
      Some simple memoization fixes this.

commit 6dca5c9099b92b6a93071197aa606a31ccd83a37
Author: Eelco Dolstra <e.dolstra@tudelft.nl>

    * When obtaining derivations from Nix expressions, ignore all
      expressions that cause an assertion failure (like `assert system ==
      "i686-linux"').  This allows all-packages.nix in Nixpkgs to be used
      on all platforms, even if some Nix expressions don't work on all
      platforms.

      Not sure if this is a good idea; it's a bit hacky.  In particular,
      due to laziness some derivations might appear in `nix-env -qa' but
      disappear in `nix-env -qas' or `nix-env -i'.

    * A script to remove from a manifest those patches whose base or
      target no longer applies to any available release.  This is a
      partial fix for NIX-34 (when producing linear patch sequences
      between releases, the number of patches grows without bound).

    * A simple hack to fix NIX-18: the garbage collector cannot run when
      the disk is full (because to delete something from the Nix store, we
      need a Berkeley DB transaction, which takes up disk space).  Under
      normal operation, we make sure that there exists a file
      /nix/var/nix/db/reserved of 1 MB.  When running the garbage
      collector, we delete that file before we open the Berkeley DB
      environment.

    * Optional switch "--with-openssl=<PATH>" to use OpenSSL's
      implementations of MD5, SHA-1 and SHA-256.  The main benefit is that
      we get assembler-optimised implementations of MD5 and SHA-1 (though
      not SHA-256 (at least on x86), unfortunately).  OpenSSL's SHA-1
      implementation on Intel is twice as fast as ours.

    * Valgrind suppressions for the ATerm library.  The ATerm library uses
      a conservative garbage collector that scans the stack and parts of
      the heap for pointers to ATerms.  This scan can touch uninitialised
      memory, which is harmless.  Use:

      $ valgrind --suppressions=aterm-gc.supp ...

      derivation(s) we're interested, e.g.,

        $ nix-instantiate ./all-packages.nix --attr xlibs.libX11

      List elements can also be selected:

        $ nix-instantiate ./build-for-release.nix --attr 0.subversion

      This allows a non-ambiguous specification of a derivation.  Of
      course, this should also be added to nix-env and nix-build.

    * Use setsid instead of setpgrp in child processes.  This not only
      creates a new process group but also a new session.  New sessions
      have no controlling tty, so child processes like ssh cannot open
      /dev/tty (which is bad).

    * When killing a build hook, kill the entire process group (as
      intended).  This ensures that any ssh child processes to remote
      machines are also killed, and thus the Nix process on the remote
      machine also exits.  Without this, the remote Nix process will
      continue until it exists or until its stdout buffer gets full and it
      locks up.  (Partially fixes NIX-35.)

    * New tools nix-pack-closure and nix-unpack-closure.  These provide a
      useful way to transfer the closure of a store path to another
      machine.

      These commands provide functionality previously possible through
      `nix-push --copy'.  However, they are much more convenient in many
      situations (though possibly less efficient).

      Example:
      $ nix-pack-closure /nix/store/hj232g1r...-subversion-1.3.0 > svn.closure
      (on another machine:)
      $ nix-unpack-closure < svn.closure

      Note that Subversion is added to the store, but not installed into a
      user environment.  One should do `nix-env -i
      /nix/store/hj232g1r...-subversion-1.3.0' for that.

      Another example: copy the application Azureus to the machine
      `scratchy' through ssh:

      $ nix-pack-closure $(which azureus) | ssh scratchy nix-unpack-closure

    * Added a flag `--ignore-liveness' to `nix-store --delete'.  It
      deletes a path even if it is reachable from a root.  However, it
      won't delete a path that still has referrers (since that would
      violate store invariants).

      Don't try this at home.  It's a useful hack for recovering from
      certain situations in a somewhat clean way (e.g., holes in closures
      due to disk corruption).

    * Revived the old "nix-store --delete" operation that deletes the

Date:   Mon Dec 12 18:24:42 2005 +0000

    * Fix NIX-23: quadratic complexity in maintaining the referers
      mapping.  The referer table is replaced by a referrer table (note
      spelling fix) that stores each referrer separately.  That is,
      instead of having

        referer[P] = {Q_1, Q_2, Q_3, ...}

      we store

        referer[(P, Q_1)] = ""
        referer[(P, Q_2)] = ""
        referer[(P, Q_3)] = ""
        ...

      To find the referrers of P, we enumerate over the keys with a value
      lexicographically greater than P.  This requires the referrer table
      to be stored as a B-Tree rather than a hash table.

      (The tuples (P, Q) are stored as P + null-byte + Q.)

      Old Nix databases are upgraded automatically to the new schema.

    * Add a test to demonstrate the quadratic complexity of referrer
      (de)registration, in particular garbage collection (NIX-23).

    * Install signal handlers for SIGTERM and SIGHUP.  This ensures that
      Nix is properly shut down when it receives those signals.  In
      particular this ensures that killing the garbage collector doesn't
      cause a subsequent database recovery.

    * Memoise checkVarDefs since internally produced terms (i.e., not the

      trees!

    * Don't use FIFOs to make Nix create the output path on behalf of the
      builder.  Instead, require that the Nix store has sticky permission
      (S_ISVTX); everyone can created files in the Nix store, but they
      cannot delete, rename or modify files created by others.

    * Beginning of secure multi-user Nix stores.  If Nix is started as
      root (or setuid root), then builds will be performed under one of
      the users listed in the `build-users' configuration variables.  This
      is to make it impossible to influence build results externally,
      allowing locally built derivations to be shared safely between
      users (see ASE-2005 paper).

      To do: only one builder should be active per build user.

commit b87b9c0d1fcbce045f05379d0efe9ae14d0f87e6

    * New query option: `--compare-versions' or `-c' to compare installed
      versions to available versions, or vice versa.

      For example, the following compares installed versions to available
      versions:

        $ nix-env -qc
        autoconf-2.59            = 2.59
        automake-1.9.4           < 1.9.6
        f-spot-0.0.10            - ?
        firefox-1.0.4            < 1.0.7
        ...

      I.e., there are newer versions available (in the current default Nix
      expression) for Automake and Firefox, but not for Autoconf, and
      F-Spot is missing altogether.

      Conversely, the available versions can be compared to the installed
      versions:

        $ nix-env -qac
        autoconf-2.59                  = 2.59
        automake-1.9.6                 > 1.9.4
        bash-3.0                       - ?
        firefox-1.0.7                  > 1.0.4
        ...

      Note that bash is available but no version of it is installed.

      If multiple versions are available for comparison, then the highest
      is used.  E.g., if Subversion 1.2.0 is installed, and Subversion
      1.1.4 and 1.2.3 are available, then `nix-env -qc' will print `<
      1.2.3', not `> 1.1.4'.

      If higher versions are available, the version column is printed in
      red (using ANSI escape codes).

    * Don't use IPC::Open2, it has a subtle race bug on Mac OS X 10.4.  If
      the parent runs before the child, it closes some pipe file
      descriptors which causes the child to fail due to a bad file
      descriptor.  So we just use the normal open() function instead.

      This fixes NIX-14 (intermittent nix-pull failures).

    * `dependencyClosure' now allows a search path, e.g.,

        dependencyClosure { ... searchPath = [ ../foo ../bar ]; ... }

    * Primop `dirOf' to return the directory part of a path (e.g., dirOf
      /a/b/c == /a/b).

    * Primop `relativise' (according to Webster that's a real word!) that
      given paths A and B returns a string representing path B relative
      path to A; e.g., relativise /a/b/c a/b/x/y => "../x/y".

    * A primitive operation `dependencyClosure' to do automatic dependency
      determination (e.g., finding the header files dependencies of a C
      file) in Nix low-level builds automatically.

      For instance, in the function `compileC' in make/lib/default.nix, we
      find the header file dependencies of C file `main' as follows:

        localIncludes =
          dependencyClosure {
            scanner = file:
              import (findIncludes {
                inherit file;
              });
            startSet = [main];
          };

      The function works by "growing" the set of dependencies, starting
      with the set `startSet', and calling the function `scanner' for each
      file to get its dependencies (which should yield a list of strings
      representing relative paths).  For instance, when `scanner' is
      called on a file `foo.c' that includes the line

        #include "../bar/fnord.h"

      then `scanner' should yield ["../bar/fnord.h"].  This list of
      dependencies is absolutised relative to the including file and added
      to the set of dependencies.  The process continues until no more
      dependencies are found (hence its a closure).

      `dependencyClosure' yields a list that contains in alternation a
      dependency, and its relative path to the directory of the start
      file, e.g.,

        [ /bla/bla/foo.c
          "foo.c"
          /bla/bar/fnord.h
          "../bar/fnord.h"
        ]

      These relative paths are necessary for the builder that compiles
      foo.c to reconstruct the relative directory structure expected by
      foo.c.

      The advantage of `dependencyClosure' over the old approach (using
      the impure `__currentTime') is that it's completely pure, and more
      efficient because it only rescans for dependencies (i.e., by
      building the derivations yielded by `scanner') if sources have
      actually changed.  The old approach rescanned every time.

    * In nix-instantiate, at top-level, call functions that have arguments
      with default values automatically.  I.e., e -> e {}.

      This feature makes convenience expressions such as
      pkgs/system/i686-linux.nix in Nixpkgs obsolete, since we can just do

      $ nix-instantiate ./pkgs/system/all-packages.nix

      since all-packages.nix takes a single argument (system) that has a
      default value (__thisSystem).

      machines (because bsdiff does everything in memory requiring
      max(17*n,9*n+m)+O(1) bytes, so the address space simply isn't
      there).

      `removeAttrs attrs ["x", "y"]' returns the set `attrs' with the
      attributes named `x' and `y' removed.  It is not an error for the
      named attributes to be missing from the input set.

    Commit 3000!

    * Make the `derivation' primitive much more lazy.  The expression
      `derivation attrs' now evaluates to (essentially)

        attrs // {
          type = "derivation";
          outPath = derivation! attrs;
          drvPath = derivation! attrs;
        }

      where `derivation!' is a primop that does the actual derivation
      instantiation (i.e., it does what `derivation' used to do).  The
      advantage is that it allows commands such as `nix-env -qa' and
      `nix-env -i' to be much faster since they no longer need to
      instantiate all derivations, just the `name' attribute.  (However,
      `nix-env' doesn't yet take advantage of this since it still always
      evaluates the `outPath' and `drvPath' attributes).

      Also, this allows derivations to cyclically reference each other,
      for example,

        webServer = derivation {
          ...
          hostName = "svn.cs.uu.nl";
          services = [svnService];
        };

        svnService = derivation {
          ...
          hostName = webServer.hostName;
        };

      Previously, this would yield a black hole (infinite recursion).

    * Check for duplicate attributes and formal parameters in Nix
      expressions.

commit 97c93526da4dfba1b92a11fb8522c07456d9e1ec
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Mar 7 16:26:05 2005 +0000

    * In the checker, do traversals of the dependency graph explicitly.  A
      conditional expression in the blacklist can specify when to
      continue/stop a traversal.  For example, in

        <condition>
          <within>
            <traverse>
              <not><hasAttr name='outputHash' value='.+' /></not>
            </traverse>
            <hasAttr name='outputHash' value='ef1cb003448b4a53517b8f25adb12452' />
          </within>
        </condition>

      we traverse the dependency graph, not following the dependencies of
      `fetchurl' derivations (as indicated by the presence of an
      `outputHash' attribute - this is a bit ugly).  The resulting set of
      paths is scanned for a fetch of a file with the given hash, in this
      case, the hash of zlib-1.2.1.tar.gz (which has a security bug).  The
      intent is that a dependency on zlib is not a problem if it is in a
      `fetchurl' derivation, since that's build-time only.  (Other
      build-time uses of zlib *might* be a problem, e.g., static linking.)

    * Use a weighted use heuristic to disambiguate between multiple
      occurances of a component.  If the shortest path distance between a
      component P and Q in the referers graph is D, then the contribution
      of Q to the use of P is 1 / R^D, where R >= 1, typically 2.  This
      expresses that distant indirect uses are less important than nearby
      uses.

      For instance, this can disambiguate between the bootstrap GCC in
      Nixpkgs and the GCC of the final stdenv (the former has more uses,
      but they are further away),  and between the GCC of the final stdenv
      and the GCC+G77 build (the latter has very few uses).

    * Added a disambiguation heuristic: if two components have the same
      name but differ to much in sice (by more than a factor of 3), then
      never generate a patch.

Date:   Fri Feb 25 15:42:52 2005 +0000

    * nix-install-package: Use the new (trivial) package format generated
      by the build farm.  See e.g.,
      http://catamaran.labs.cs.uu.nl/dist/nixpkgs-0.8/nixpkgs-0.7pre2302/;
      the user can click on packages, and they will be installed (assuming
      the `application/nix-package' MIME type has been associated with
      `nix-install-package').

      Nix expressions are no longer involved: a "package" is just a
      pointer to a manifest, and the top-level store derivation to be
      added to the user environment.  This makes these packages
      independent from Nix expression evolution.

      Note that we install the store derivation ($drvPath), not the
      resulting output path ($outPath).  This is equivalent, except that
      installing the derivation maintains the back-link from the output
      path to the derivation that built it.  This is useful for
      maintenance.

    * Automatically re-exec in an xterm so that the user sees something
      when `nix-install-package' is run from a browser.

    * Properly specify the hash algorithm in the manifests, and read it
      too.
    * Change the default hash for nix-prefetch-url back to md5, since
      that's what we use in Nixpkgs (for now; a birthday attack is rather
      unlikely there).

    * When multiple derivations are specified in `nix-store -r', don't
      continue building when one fails unless `--keep-going' is
      specified.
    * When `--keep-going' is specified, print out the set of failing
      derivations at the end (otherwise it can be hard to find out which
      failed).

    * Subtle bug in the builder: if a subgoal that is instantiated
      multiple times is also a top-level goal, then the second and later
      instantiations would never be created because there would be a
      stable pointer to the first one that would keep it alive in the
      WeakGoalMap.
    * Some tracing code for debugging this kind of problem.

    * `nix-store -q --tree' shows a tree representing the dependency graph
      of the given derivation.  Useful for getting a quick overview of how
      something was built.  E.g., to find out how the `baffle' program in
      your user environment was built, you can do

        $ nix-store -q --tree $(nix-store -qd $(which baffle))

      Tree nesting depth is minimised (?) by topologically sorting paths
      under the relation A < B iff A \in closure(B).

      environment elements from one user environment to another, e.g.,

        $ nix-env -i --from-profile /nix/var/nix/profiles/other-profile aterm

      copies the `aterm' component installed in the `other-profile' to the
      user's current profile.

commit 8992fce3da844e3cfc7cbc563cbf5313980c16dd
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Feb 14 17:35:10 2005 +0000

    * It is now possible to add store derivations or paths directly to a
      user environment, e.g.,

        $ nix-env -i /nix/store/z58v41v21xd3ywrqk1vmvdwlagjx7f10-aterm-2.3.1.drv

      or

        $ nix-env -i /nix/store/hsyj5pbn0d9iz7q0aj0fga7cpaadvp1l-aterm-2.3.1

      This is useful because it allows Nix expressions to be bypassed
      entirely.  For instance, if only a nix-pull manifest is provided,
      plus the top-level path of some component, it can be installed
      without having to supply the Nix expression (e.g., for obfuscation,
      or to be independent of Nix expression language changes or context
      dependencies).

commit e446d342b77e0babb200afd6b6275df2c70cfaee
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Feb 14 17:07:43 2005 +0000

    * Added an installation source `--from-expression' (or `-E') to
      install derivations from a Nix expression specified on the command
      line.  This is particularly useful for disambiguation if there are
      multiple derivations with the same name.  For instance, in Nixpkgs,
      to install the Firefox wrapper rather than the plain Firefox
      component:

        $ nix-env -f .../i686-linux.nix -i -E 'x: x.firefoxWrapper'

      The Nix expressions should be functions to which the default Nix
      expression (in this case, `i686-linux.nix') is passed, hence `x:
      ...'.

      This might also be a nice way to deal with high-level (user-level)
      variability, e.g.,

        $ nix-env -f ./server.nix -i -E 'x: x {port = 8080; ssl = false;}'

    * Global configuration option `env-keep-derivations' to store pointer
      to derivations in user environments.  Nice for developers (since it
      prevents build-time-only dependencies from being GC'ed, in
      conjunction with `gc-keep-outputs').  Turned off by default.

    * Refactoring to support different installation sources in nix-env.
    * Set the references for the user environment manifest properly.
    * Don't copy the manifest (this was accidental).
    * Don't store derivation paths in the manifest (maybe this should be
      made optional).  This cleans up the semantics of nix-env, which were
      weird.
    * Hash on the output paths of activated components, not on derivation
      paths.  This is because we don't know the derivation path of already
      installed components anymore, and it allows the installation of
      components by store path (skipping Nix expressions entirely).
    * Query options `--out-path' and `--drv-path' to show the output and
      derivation paths of components, respectively (the latter replaces
      the `--expr' query).

    * Move root finding from `nix-collect-garbage' to `nix-store --gc'.
      This was necessary becase root finding must be done after
      acquisition of the global GC lock.

      This makes `nix-collect-garbage' obsolete; it is now just a wrapper
      around `nix-store --gc'.

    * Automatically remove stale GC roots (i.e., indirect GC roots that
      point to non-existent paths).

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Feb 1 13:48:46 2005 +0000

    * nix-build: use an indirection scheme to make it easier for users to
      get rid of GC roots.  Nix-build places a symlink `result' in the
      current directory.  Previously, removing that symlink would not
      remove the store path being linked to as a GC root.  Now, the GC
      root created by nix-build is actually a symlink in
      `/nix/var/nix/gcroots/auto' to `result'.  So if that symlink is
      removed the GC root automatically becomes invalid (since it can no
      longer be resolved).  The root itself is not automatically removed -
      the garbage collector should delete dangling roots.

    * nix-store, nix-instantiate: added an option `--add-root' to
      immediately add the result as a permanent GC root.  This is the only
      way to prevent a race with the garbage collector.  For instance, the
      old style

        ln -s $(nix-store -r $(nix-instantiate foo.nix)) \
          /nix/var/nix/gcroots/result

      has two time windows in which the garbage collector can interfere
      (by GC'ing the derivation and the output, respectively).  On the
      other hand,

        nix-store --add-root /nix/var/nix/gcroots/result -r \
          $(nix-instantiate --add-root /nix/var/nix/gcroots/drv \
            foo.nix)

      is safe.

    * nix-build: use `--add-root' to prevent GC races.

    * Acquire a global GC lock to prevent new temporary root files from
      being created after the garbage collector has read the temproots
      directory.  This blocks the creation of new processes, but the
      garbage collector could periodically release the GC lock to allow
      them to run.

    * Topologically sort paths under the references relation to ensure
      that they are deleted in an order that maintains the closure

    * Presence of a path in a temporary roots file does not imply that all

    * Start of concurrent garbage collection.  Processes write temporary
      roots to a per-process temporary file in /nix/var/nix/temproots
      while holding a write lock on that file.  The garbage collector
      acquires read locks on all those files, thus blocking further
      progress in other Nix processes, and reads the sets of temporary
      roots.

      This simplifies garbage collection and `nix-store --query
      --requisites' since we no longer need to treat derivations

    * Better maintaining of the invariants, e.g., setReferences() can only
      be called on a valid/substitutable path.

    * In nix-store: added query `--referers-closure' that returns the
      closure of the referers relation rather than the references
      relation, i.e., the set of all paths that directly or indirectly

      closure this set is not fixed; it can change as paths are added to
      or removed from the store.

    * Another change to low-level derivations.  The last one this year, I
      promise :-) This allows derivations to specify on *what* output
      paths of input derivations they are dependent.  This helps to
      prevent unnecessary downloads.  For instance, a build might be
      dependent on the `devel' and `lib' outputs of some library
      component, but not the `docs' output.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Jan 19 11:16:11 2005 +0000

    * Started removing closure store expressions, i.e., the explicit
      representation of closures as ATerms in the Nix store.  Instead, the
      file system pointer graph is now stored in the Nix database.  This
      has many advantages:

      - It greatly simplifies the implementation (we can drop the notion
        of `successors', and so on).

      - It makes registering roots for the garbage collector much easier.
        Instead of specifying the closure expression as a root, you can
        simply specify the store path that must be retained as a root.
        This could not be done previously, since there was no way to find
        the closure store expression containing a given store path.

      - Better traceability: it is now possible to query what paths are
        referenced by a path, and what paths refer to a path.

commit f3dc2312501358e29b70bec977fd96f626c46392
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Jan 17 16:55:19 2005 +0000

    * Removed the `id' attribute hack.

    * Formalise the notion of fixed-output derivations, i.e., derivations
      for which a cryptographic hash of the output is known in advance.
      Changes to such derivations should not propagate upwards through the
      dependency graph.  Previously this was done by specifying the hash
      component of the output path through the `id' attribute, but this is
      insecure since you can lie about it (i.e., you can specify any hash
      and then produce a completely different output).  Now the
      responsibility for checking the output is moved from the builder to
      Nix itself.

      A fixed-output derivation can be created by specifying the
      `outputHash' and `outputHashAlgo' attributes, the latter taking
      values `md5', `sha1', and `sha256', and the former specifying the
      actual hash in hexadecimal or in base-32 (auto-detected by looking
      at the length of the attribute value).  MD5 is included for
      compatibility but should be considered deprecated.

    * Removed the `drvPath' pseudo-attribute in derivation results.  It's
      no longer necessary.

    * Cleaned up the support for multiple output paths in derivation store
      expressions.  Each output now has a unique identifier (e.g., `out',
      `devel', `docs').  Previously there was no way to tell output paths
      apart at the store expression level.

    * `nix-hash' now has a flag `--base32' to specify that the hash should
      be printed in base-32 notation.

    * `fetchurl' accepts parameters `sha256' and `sha1' in addition to
      `md5'.

    * `nix-prefetch-url' now prints out a SHA-1 hash in base-32.  (TODO: a
      flag to specify the hash.)

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri Jan 14 16:04:03 2005 +0000

    * Shorten SHA-256 hashes used in store path name generation to 160
      bits, then encode them in a radix-32 representation (using digits
      and letters except e, o, u, and t).  This produces store paths like
      /nix/store/4i0zb0z7f88mwghjirkz702a71dcfivn-aterm-2.3.1.  The nice
      thing about this is that the hash part of the file name is still 32
      characters, as before with MD5.

      (Of course, shortening SHA-256 to 160 bits makes it no better than
      SHA-160 in theory, but hopefully it's a bit more resistant to
      attacks; it's certainly a lot slower.)

Date:   Fri Jan 14 13:51:38 2005 +0000

    * Start move towards SHA-256 hashes instead of MD5.
    * Start cleaning up unique store path generation (they weren't always
      unique; in particular the suffix ("-aterm-2.2", "-builder.sh") was
      not part of the hash, therefore changes to the suffix would cause
      multiple store objects with the same hash).

Date:   Mon Dec 20 13:43:32 2004 +0000

    * Simplify the substitute mechanism:
      - Drop the store expression.  So now a substitute is just a
        command-line invocation (a program name + arguments).  If you
        register a substitute you are responsible for registering the
        expression that built it (if any) as a root of the garbage
        collector.
      - Drop the substitutes-rev DB table.

commit 862f4c154e883611ba9dfefe921c87e6423075ea
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Dec 13 13:47:38 2004 +0000

    * Patch deployment.  `download.pl' (intended to be used in the
      substitute mechanism) creates a store path by downloading full NAR
      archives and/or patches specified in the available manifests.

      Any combination of present paths, full downloads, and patches can be
      used to construct the target path.  In particular, patches can be
      chained in sequence; and full NAR archives of the target path can be
      omitted (i.e., patch-only deployment is possible).  A shortest path
      algorithm is used to find the smallest set of files to be downloaded
      (the edge weights are currently file sizes, but one can imagine
      taking the network speed to the various source into account).

      Patches are binary deltas between two store paths.  To be precise,
      they are the output of the `bsdiff' program applied to the NAR
      archives obtained by dumping (`nix-store --dump') the two store
      paths.  The advantage of diff'ing NAR archives (and not, say, doing
      file-by-file diffs) is that file renames/moves are handled
      automatically.  The disadvantage is that we cannot optimise creation
      of unchanged files (by hard-linking).

    * Mode `--parse-only' to parse the input (on stdin, `-'), and print
      out the AST as an ATerm.
    * Mode `--eval-only' to parse and evaluate the input, and print the
      resulting normal form as an ATerm.

    Neither of these modes require store/DB write permission.

    * New language feature: with expressions.

      The expression `with E1; E2' evaluates to E2 with all bindings in
      the attribute set E1 substituted.  E.g.,

        with {x = 123;}; x

      evaluates to 123.  That is, the attribute set E1 is in scope in E2.

      This is particularly useful when importing files containing lots
      definitions.  E.g., instead of

        let {
          inherit (import ./foo.nix) a b c d e f;

          body = ... a ... f ...;
        }

      we can now say

        with import ./foo.nix;

        ... a ... f ...

      I.e., we don't have to say what variables should be brought into scope.

    * Allow certain operations to succeed even if we don't have write
      permission to the Nix store or database.  E.g., `nix-env -qa' will
      work, but `nix-env -qas' won't (the latter needs DB access).  The
      option `--readonly-mode' forces this mode; otherwise, it's only
      activated when the database cannot be opened.

    * Fallback didn't work for subderivations of an unnormalised the main
      derivation, since NormalisationGoal would first run a
      NormalisationGoal on the subderivation (a no-op, since in a
      situation where we need fallback the successor is known), and then
      runs a RealisationGoal on the normal form, which then cannot do a
      fallback because it doesn't know the derivation expression for which
      it is a normal form.

      Tossed out the 2-phase normalisation/realisation in
      NormalisationGoal and SubstitutionGoal since it's no longer needed -
      a RealisationGoal will run a NormalisationGoal if necessary.

    * A very dirty hack to make setuid installations a bit nicer to use.
      Previously there was the problem that all files read by nix-env
      etc. should be reachable and readable by the Nix user.  So for
      instance building a Nix expression in your home directory meant that
      the home directory should have at least g+x or o+x permission so
      that the Nix user could reach the Nix expression.  Now we just
      switch back to the original user just prior to reading sources and
      the like.  The places where this happens are somewhat arbitrary,
      however.  Any scope that has a live SwitchToOriginalUser object in
      it is executed as the original user.

    * Back out r1385.  setreuid() sets the saved uid to the new
      real/effective uid, which prevents us from switching back to the
      original uid.  setresuid() doesn't have this problem (although the
      manpage has a bug: specifying -1 for the saved uid doesn't leave it
      unchanged; an explicit value must be specified).

    * Use setre[ug]id() instead of setres[ug]id(), since the former is
      more common than the latter (which exists only on Linux and
      FreeBSD).  We don't really care about dropping the saved IDs since
      there apparently is no way to quiry them in any case, so it can't
      influence the build (unlike the effective IDs which are checked by
      Perl for instance).

    * Set the umask to known value (0022).  This is important in a
      setuid installation, since the calling user may have a more fascist
      umask (say, 0077), which would cause the store objects built by Nix
      to be unreadable to anyone other than the Nix user.

    * `--min-age' flag in nix-store and nix-collect-garbage to only delete
      unreachable paths that haven't been used for N hours.  For instance,
      `nix-collect-garbage --min-age 168' only deletes paths that haven't
      been accessed in the last week.

      This is useful for instance in the build farm where many derivations
      can be shared between consecutive builds, and we wouldn't want a
      garbage collect to throw them all away.  We could of course register
      them as roots, but then we'd to unregister them at some point, which
      would be a pain to manage.  The `--min-age' flag gives us a sort of
      MRU caching scheme.

      BUG: this really shouldn't be in gc.cc since that violates
      mechanism/policy separation.

    * `nix-collect-garbage' now actually performs a garbage collection, it
      doesn't just print the set of paths that should be deleted.  So
      there is no more need to pipe the result into `nix-store --delete'
      (which doesn't even exist anymore).

    * Put the garbage collector in nix-store: operation `--gc',
      suboperations `--print-live', `--print-dead', and `--delete'.  The
      roots are not determined by nix-store; they are read from standard
      input.  This is to make it easy to customise what the roots are.

      The collector now no longer fails when store expressions are missing
      (which legally happens when using substitutes).  It never tries to
      fetch paths through substitutes.

      TODO: acquire a global lock on the store while garbage collecting.

    * Removed `nix-store --delete'.

    * On systems that have the setresuid() and setresgid() system calls to
      set the real uid and gid to the effective uid and gid, the Nix
      binaries can be installed as owned by the Nix user and group instead
      of root, so no root involvement of any kind is necessary.

      Linux and FreeBSD have these functions.

    * Setuid support for sharing a Nix installation between multiple
      users.

      If the configure flag `--enable-setuid' is used, the Nix programs
      nix-env, nix-store, etc. are installed with the setuid bit turned on
      so that they are executed as the user and group specified by
      `--with-nix-user=USER' and `--with-nix-group=GROUP', respectively
      (with defaults `nix' and `nix').

      The setuid programs drop all special privileges if they are executed
      by a user who is not a member of the Nix group.

      The setuid feature is a quick hack to enable sharing of a Nix
      installation between users who trust each other.  It is not
      generally secure, since any user in the Nix group can modify (by
      building an appropriate derivation) any object in the store, and for
      instance inject trojans into binaries used by other users.

      The setuid programs are owned by root, not the Nix user.  This is
      because on Unix normal users cannot change the real uid, only the
      effective uid.  Many programs don't work properly when the real uid
      differs from the effective uid.  For instance, Perl will turn on
      taint mode.  However, the setuid programs drop all root privileges
      immediately, changing all uids and gids to the Nix user and group.

    * Nix-env operations now by default filter out any derivations for
      system types other than the current system.  I.e., `nix-env -i'
      won't install derivations for other system types, and `nix-env -q'
      won't show them.  The flag `--system-filter SYSTEM' can be used to
      override the system type used for filtering (but not for
      building!).  The value `*' can be used not to filter anything.

Date:   Mon Jun 28 10:42:57 2004 +0000

    * Added a switch `--fallback'.  From the manual:

      Whenever Nix attempts to realise a derivation for which a closure is
      already known, but this closure cannot be realised, fall back on
      normalising the derivation.

      The most common scenario in which this is useful is when we have
      registered substitutes in order to perform binary distribution from,
      say, a network repository.  If the repository is down, the
      realisation of the derivation will fail.  When this option is
      specified, Nix will build the derivation instead.  Thus, binary
      installation falls back on a source installation.  This option is
      not the default since it is generally not desirable for a transient
      failure in obtaining the substitutes to lead to a full build from
      source (with the related consumption of resources).

    * A flag `--keep-going / -k' to keep building goals if one fails, as
      much as possible.  (This is similar to GNU Make's `-k' flag.)

    * Refactoring to implement this: previously we just bombed out when
      a build failed, but now we have to clean up.  In particular this
      means that goals must be freed quickly --- they shouldn't hang
      around until the worker exits.  So the worker now maintains weak
      pointers in order not to prevent garbage collection.

    * Documented the `-k' and `-j' flags.

    * Re-enable support for substitutes in the normaliser.

    * A better substitute mechanism.

      Instead of generating a store expression for each store path for
      which we have a substitute, we can have a single store expression
      that builds a generic program that is invoked to build the desired
      store path, which is passed as an argument.

      This means that operations like `nix-pull' only produce O(1) files
      instead of O(N) files in the store when registering N substitutes.
      (It consumes O(N) database storage, of course, but that's not a
      performance problem).

    * Added a test for the substitute mechanism.

    * `nix-store --substitute' reads the substitutes from standard input,
      instead of from the command line.  This prevents us from running
      into the kernel's limit on command line length.

    * The build hooks used to implement distributed builds can now be run
      in parallel.  Hooks are more efficient: locks on output paths are
      only acquired when the hook says that it is willing to accept a
      build job.  Hooks now work in two phases.  First, they should first
      tell Nix whether they are willing to accept a job.  Nix guarantuees
      that no two hooks will ever be in the first phase at the same time
      (this simplifies the implementation of hooks, since they don't have
      to perform locking (?)).  Second, if they accept a job, they are
      then responsible for building it (on the remote system), and copying
      the result back.  These can be run in parallel with other hooks and
      locally executed jobs.

      The implementation is a bit messy right now, though.

    * The directory `distributed' shows a (hacky) example of a hook that
      distributes build jobs over a set of machines listed in a
      configuration file.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue May 11 18:05:44 2004 +0000

    * True parallel builds.  Nix can now run as many build jobs in
      parallel as possible (similar to GNU Make's `-j' switch).  This is
      useful on SMP systems, but it is especially useful for doing builds
      on multiple machines.  The idea is that a large derivation is
      initiated on one master machine, which then distributes
      sub-derivations to any number of slave machines.  This should not
      happen synchronously or in lock-step, so the master must be capable
      of dealing with multiple parallel build jobs.  We now have the
      infrastructure to support this.

      TODO: substitutes are currently broken.

    * Channels.  These allow you to stay current with an evolving set of
      Nix expressions.

      To subscribe to a channel (needs to be done only once):

        nix-channel --add \
          http://catamaran.labs.cs.uu.nl/dist/nix/channels/nixpkgs-unstable

      This just adds the given URL to ~/.nix-channels (which can also be
      edited manually).

      To update from all channels:

        nix-channel --update

      This fetches the latest expressions and pulls cache manifests.  The
      default Nix expression (~/.nix-defexpr) is made to point to the
      conjunction of the expressions downloaded from all channels.

      So to update all installed derivations in the current user
      environment:

        nix-channel --update
        nix-env --upgrade '*'

      If you are really courageous, you can put this in a cronjob or
      something.

      You can subscribe to multiple channels.  It is not entirely clear
      what happens when there are name clashes between derivations from
      different channels.  From nix-env/main.cc it appears that the one
      with the lowest (highest?) hash will be used, which is pretty
      meaningless.

    * When something goes wrong in the evaluation of a Nix expression,
      print a nice backtrace of the stack, rather than vomiting a gigantic
      (and useless) aterm on the screen.  Example:

        error: while evaluating file `.../pkgs/system/test.nix':
        while evaluating attribute `subversion' at `.../pkgs/system/all-packages-generic.nix', line 533:
        while evaluating function at `.../pkgs/applications/version-management/subversion/default.nix', line 1:
        assertion failed at `.../pkgs/applications/version-management/subversion/default.nix', line 13

      Since the Nix expression language is lazy, the trace may be
      misleading.  The purpose is to provide a hint as to the location of
      the problem.

    * Print a more useful error message in case of an invalid derivation

commit c4ac2a164af1c4198852844ae4fcfb99c7e8c110
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Tue Mar 30 15:05:35 2004 +0000

    * The recent change in nixpkgs of calling `stdenv.mkDerivation'
      instead of `derivation' triggered a huge slowdown in the Nix
      expression evaluator.  Total execution time of `nix-env -qa' went up
      by a factor of 60 or so.

      This scalability problem was caused by expressions such as

        (x: y: ... x ...) a b

      where `a' is a large term (say, the one in
      `all-packages-generic.nix').  Then the first beta-reduction would
      produce

        (y: ... a ...) b

      by substituting `a' for `x'.  The second beta-reduction would then
      substitute `b' for `y' into the body `... a ...', which is a large
      term due to `a', and thus causes a large traversal to be performed
      by substitute() in the second reduction.  This is however entirely
      redundant, since `a' cannot contain free variables (since we never
      substitute below a weak head normal form).

      The solution is to wrap substituted terms into a `Closed'
      constructor, i.e.,

        subst(subs, Var(x)) = Closed(e) iff subs[x] = e

      have substitution not descent into closed terms,

        subst(subs, Closed(x)) = Closed(x)

      and otherwise ignore them for evaluation,

        eval(Closed(x)) = eval(x).

    * Fix a typo that caused incorrect substitutions to be performed in
      simple lambdas, e.g., `(x: x: x) a' would reduce to `(x: a)'.

          ...
        }

      Here the attribute `builder' will evaluate to, e.g.,
      `/nix/store/1234abcd...-bash-2.0.1/bin/sh'.

        builder = /usr/bin/python;
        args = ["-c" ./builder.py];
        ...

    * Disallow the Nix store or any of its parents from being symlinks.
      This is because the contents of these symlinks are not incorporated
      into the hashes of derivations, and could therefore cause a mismatch
      between the build system and the target system.  E.g., if
      `/nix/store' is a symlink to `/data/nix/store', then a builder could
      expand this path and store the result.  If on the target system
      `/nix/store' is not a symlink, or is a symlink that points somewhere
      else, we have a dangling pointer.

      The trigger for this change is that gcc 3.3.3 does exactly that (it
      applies realpath() to some files, such as libraries, which causes
      our impurity checker to bail out.)

      An annoying side-effect of this change is that it makes it harder to
      move the Nix store to a different file system.  On Linux, bind
      mounts can be used instead of symlink for this purpose (e.g., `mount
      -o bind /data/nix/store /nix/store').

      - `pretty': the old nested style (default)
      - `escapes': uses escape codes to indicate nesting and message
        level; can be processed using `log2xml'
      - `flat': just plain text, no nesting

      These can be set using `--log-type TYPE' or the NIX_LOG_TYPE
      environment variable.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Mar 15 21:51:14 2004 +0000

    * Added a utility that can be used to produce nice HTML pages from Nix
      build logs.  The program `log2xml' converts a Nix build log (read
      from standard input) into XML file that can then be converted to
      XHTML by the `log2html.xsl' stylesheet.  The CSS stylesheet
      `logfile.css' is necessary to make it look good.

      This is primarily useful if the log file has a *tree structure*,
      i.e., that sub-tasks such as the various phases of a build (unpack,
      configure, make, etc.) or recursive invocations of Make are
      represented as such.  While a log file is in principle an
      unstructured plain text file, builders can communicate this tree
      structure to `log2xml' by using escape sequences:

      - "\e[p" starts a new nesting level; the first line following the
        escape code is the header;

      - "\e[q" ends the current nesting level.

      The generic builder in nixpkgs (not yet committed) uses this.  It
      shouldn't be to hard to patch GNU Make to speak this protocol.

      Further improvements to the generated HTML pages are to allow
      collapsing/expanding of subtrees, and to abbreviate store paths (but
      to show the full path by hovering the mouse over it).

    * Set the NIX_STORE and NIX_BUILD_TOP environment variables in
      builders to point to the store and the temporary build directory,
      respectively.  Useful for purity checking.
    * Also set TEMPDIR, TMPDIR, TEMP, and TEMP to NIX_BUILD_TOP to make
      sure that tools in the builder store temporary files in the right
      location.

      constant code/data should be separate from the initialisation of
      mutable state.

      whether we want to upgrade if the current version is less than the
      available version (default), when it is less or equal, or always.

    * Added a flag `--dry-run' to show what would happen in `--install',
      `--uninstall', and `--upgrade', without actually performing the
      operation.

commit 06a75a7e0c1813d90c205e654da43a32812ce5f4
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Sun Feb 8 14:07:43 2004 +0000

    * A command `--switch-generation' to switch to a specific generation
      of the current profile, e.g.,

        $ nix-env --list-generations
        ...
        39   2004-02-02 17:53:53
        40   2004-02-02 17:55:18
        41   2004-02-02 17:55:41
        42   2004-02-02 17:55:50   (current)

        $ nix-env --switch-generation 39

        $ ls -l /nix/var/nix/profiles/default
        ... default -> default-39-link

    * Also a command `--rollback' which is just a convenience operation to
      rollback to the oldest generation younger than the current one.

      Note that generations properly form a tree.  E.g., if after
      switching to generation 39, we perform an installation action,
      a generation 43 is created which is a descendant of 39, not 42.  So
      a rollback from 43 ought to go back to 39.  This is not currently
      implemented; generations form a linear sequence.

    * Improvements to profiles.  Generations are now per-profile, e.g.,

      default -> default-94-link
      default-82-link -> /nix/store/cc4480...
      default-83-link -> /nix/store/caeec8...
      ...
      default-94-link -> /nix/store/2896ca...
      experimental -> experimental-2-link
      experimental-1-link -> /nix/store/cc4480...
      experimental-2-link -> /nix/store/a3148f...

    * `--profile' / `-p' -> `--switch-profile' / `-S'
    * `--link' / `-l' -> `--profile' / `-p'
    * The default profile is stored in $prefix/var/nix/profiles.
      $prefix/var/nix/links is gone.  Profiles can be stored anywhere.
    * The current profile is now referenced from ~/.nix-profile, not
      ~/.nix-userenv.
    * The roots to the garbage collector now have extension `.gcroot', not
      `.id'.

    * Extended the `inherit' syntax to optionally select attributes from
      other attribute sets, rather than the current scope.  E.g.,

        {inherit (pkgs) gcc binutils;}

      is equivalent to

        {gcc = pkgs.gcc; binutils = pkgs.binutils;}

      I am not so happy about the syntax.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Feb 2 21:39:33 2004 +0000

    * Added syntactic sugar to the construction of attribute sets to
      `inherit' variables from the surrounding lexical scope.

      E.g.,

        {stdenv, libfoo}: derivation {
          builder = ./bla;
          inherit stdenv libfoo;
          xyzzy = 1;
        }

      is equivalent to

        {stdenv, libfoo}: derivation {
          builder = ./bla;
          stdenv = stdenv;
          libfoo = libfoo;
          xyzzy = 1;
        }

      Note that for mutually recursive attribute set definitions (`rec
      {...}'), this also works, that is, `rec {inherit x;}' is equivalent
      to `let {fresh = x; body = rec {x = fresh;};}', *not*
      `rec {x = x}'.

      parser (roughly 80x faster).

      The absolutely latest version of Bison (1.875c) is required for
      reentrant GLR support, as well as a recent version of Flex (say,
      2.5.31).  Note that most Unix distributions ship with the
      prehistoric Flex 2.5.4, which doesn't support reentrancy.

    * Catch SIGINT to terminate cleanly when the user tries to interrupt
      Nix.  This is to prevent Berkeley DB from becoming wedged.

      Unfortunately it is not possible to throw C++ exceptions from a
      signal handler.  In fact, you can't do much of anything except
      change variables of type `volatile sig_atomic_t'.  So we set an
      interrupt flag in the signal handler and check it at various
      strategic locations in the code (by calling checkInterrupt()).
      Since this is unlikely to cover all cases (e.g., (semi-)infinite
      loops), sometimes SIGTERM may now be required to kill Nix.

      expression.  This ensures that changes that affect the path of the
      store expression but not the output path, do not affect the
      `installed' state of a derivation.

    * Improved `nix-push': it now uses HTTP PUT (instead of rsync) to copy
      files.  Target location is no longer hard-coded; it accepts a number
      of URLs on the command line.

    * `nix-install-package': compatibility fixes.

    * Upgraded to Berkeley DB 4.2.52.  The main advantage of 4.2 is that
      it automatically removes log files when they are no longer needed.

      *** IMPORTANT ***

      If you have an existing Nix installation, you must checkpoint the
      Nix database to prevent recent transactions from being undone.  Do
      the following:

      - optional: make a backup of $prefix/var/nix/db.

      - run `db_checkpoint' from Berkeley DB 4.1:

        $ db_checkpoint -h $prefix/var/nix/db -1

      - optional (?): run `db_recover' from Berkeley DB 4.1:

        $ db_recover -h $prefix/var/nix/db

      - remove $prefix/var/nix/db/log* and $prefix/var/nix/db/__db*

commit 4a373a3e9ac07a2d4c43d495c0a44883106ecfde
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Jan 5 16:26:43 2004 +0000

    * Implemented Eelco V.'s `nix-env -I' command to specify the default
      path of the Nix expression to be used with the import, upgrade, and
      query commands.  For instance,

      $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix

      $ nix-env --query --available   [aka -qa]
      sylpheed-0.9.7
      bison-1.875
      pango-1.2.5
      subversion-0.35.1
      ...

      $ nix-env -i sylpheed

      $ nix-env -u subversion

      There can be only one default at a time.

    * If the path to a Nix expression is a symlink, follow the symlink
      prior to resolving relative path references in the expression.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Jan 5 11:18:59 2004 +0000

    * Implemented Eelco V.'s `-p' command to switch profiles.  It switches
      the symlink ~/.nix-userenv to the given argument (which defaults to
      .../links/current).  /etc/profile.d/nix-profile creates this symlink
      if it doesn't exist yet.  Example use:

      $ nix-env -l my_profile -i foo.nix subversion quake
      $ nix-env -p my_profile

      I don't like the term "profile".  Let's deprecate it :-)

commit cf0287c09e8b5816c65dd265c4ef167865d70172
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Mon Dec 22 16:04:00 2003 +0000

    * Upgrade operation in `nix-env'.  For instance, you can say

        nix-env -u foo.nix strategoxt

      to replace the installed `strategoxt' derivation with the one from `foo.nix', if
      the latter has a higher version number.  This is a no-op if `strategoxt' is not
      installed.  Wildcards are also accepted, so

        nix-env -u foo.nix '*'

      will replace any installed derivation with newer versions from `foo.nix', if
      available.

      The notion of "version number" is somewhat ad hoc, but should be useful in most
      cases, as evidenced by the following unit tests for the version comparator:

        TEST("1.0", "2.3", -1);
        TEST("2.1", "2.3", -1);
        TEST("2.3", "2.3", 0);
        TEST("2.5", "2.3", 1);
        TEST("3.1", "2.3", 1);
        TEST("2.3.1", "2.3", 1);
        TEST("2.3.1", "2.3a", 1);
        TEST("2.3pre1", "2.3", -1);
        TEST("2.3pre3", "2.3pre12", -1);
        TEST("2.3a", "2.3c", -1);
        TEST("2.3pre1", "2.3c", -1);
        TEST("2.3pre1", "2.3q", -1);

      (-1 = less, 0 = equal, 1 = greater)

    * A new verbosity level `lvlInfo', between `lvlError' and `lvlTalkative'.  This is
      the default for `nix-env', so without any `-v' flags users should get useful
      output, e.g.,

    $ nix-env -u foo.nix strategoxt
    upgrading `strategoxt-0.9.2' to `strategoxt-0.9.3'

    * Version numbers can be omitted in install/uninstall.  E.g.,

        nix-env -i foo.nix subversion

      The version number part of a derivation name is defined as everything following the
      first dash not followed by a letter.

      unpacks it, pulls the caches, and installs the derivations in the
      user's environment.

      For best results, associate the command `xterm -e
      /nix/bin/nix-install-package' with the MIME type
      `application/x-nix-package' and visit
      http://losser.st-lab.cs.uu.nl/~eelco/test/.

    * Turned the msg() and debug() functions into macros, since they
      turned out to be a huge performance bottleneck (the text to printed
      would always be evaluated, even when it was above the verbosity
      level).  This reduces fix-ng execution time by over 50%.

      gprof(1) is very useful. :-)

    * Work around problems with the ATerm library.

      The ATerm library doesn't search the heap for pointers to ATerms
      when garbage collecting.  As a result, C++ containers such as
      `map<ATerm, ATerm>' will cause pointer to be hidden from the garbage
      collector, causing crashes.  Instead, we now use ATermTables.

    * Use SGparseString() instead of SGparseFile() because the latter is

    * Ad hoc per-package logging.  When Nix performs a derivation, it now
      writes stdout/stderr of the builder to ${prefix}/var/log/nix/x,
      where x is the file name of the derivation expression, e.g.,

        /nix/var/log/nix/54256391624be04fcb426048ae3ea0a4-d-pan-0.14.2.nix

      Note that consecutive builds of the same expression overwrite,
      rather than append to, existing log files.

commit f7c7aad1351a0ed58f458e485968af498d542b5b
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Thu Oct 16 08:52:44 2003 +0000

    * Upgraded to Berkeley DB 4.1.25 and do not synchronously flush the
      log on commit.  This means that there is a small change that some
      transactions may be rolled back in case of a system crash, but this
      should not be a problem (it merely might cause some expression
      realisations to be rolled back), and it vastly improves performance.

    * Upgraded to ATerm 2.0.5 (which also includes Armijn's 64-bit
      patches).

    * Get rid of identifiers since they are redundant now.  This greatly
      simplifies stuff.

    * The format of Nix expressions and the database schema changed

    * Remove write permission from output paths after they have been built.
    * Point $HOME to a non-existing path when building to prevent certain tools (such as
      wget) from falling back on /etc/passwd to locate the home directory (which we
      don't want them to look at since it's not declared as an input).

    * Use maps and sets in the FState data type.  This ensures normalisation of
      slices and derivations w.r.t. order of paths, slice elements, etc.

commit 624c48260f1b4eec86daa0da5f33d4cbb963a361
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Wed Aug 20 12:39:56 2003 +0000

    * Change the abstract syntax of slices.  It used to be that ids were used as
      keys to reference slice elements, e.g.,

        Slice(["1ef7..."], [("/nix/store/1ef7...-foo", "1ef7", ["8c99..."]), ...])

      This was wrong, since ids represent contents, not locations.  Therefore we
      now have:

        Slice(["/nix/store/1ef7..."], [("/nix/store/1ef7...-foo", "1ef7", ["/nix/store/8c99-..."]), ...])

    * Fix a bug in the computation of slice closures that could cause slice
      elements to be duplicated.

    * Allow lists in package bindings, e.g.,

        ("srcs", [Relative("foo/bar.c"), Relative("foo/baz.h")])

      The result is an environment variable that contains the path names of the
      inputs separated by spaces (so this is not safe for values containing
      spaces).

      builder using the `args' binding:

    * Allow locks on paths to be acquired recursively (that is, if the
      process is already holding a lock on a path, it may acquire the lock
      again without blocking or failing).  (This might be dangerous, not
      sure).  Necessary for fast builds to work.

    * A flag `--flat' to just compute the MD5 checksum of the contents of

      arbitrarily, while registered paths can only be deleted by running
      the garbage collector.

    * Get garbage collection and cache population to work *properly*.
      Renamed `fstateRefs' to `fstateRequisites'.  The semantics of this
      function is that it returns a list of all paths necessary to realise
      a given expression.  For a derive expression, this is the union of
      requisites of the inputs; for a slice expression, it is the path of
      each element in the slice.  Also included are the paths of the
      expressions themselves.  Optionally, one can also include the
      requisites of successor expressions (to recycle intermediate
      results).

    * `nix-switch' now distinguishes between an expression and its normal
      form.  Usually, only the normal form is registered as a root of the
      garbage collector.  With the `--source-root' flag, it will also
      register the original expression as a root.

    * `nix-collect-garbage' now has a flag `--keep-successors' which
      causes successors not to be included in the list of garbage paths.

    * `nix-collect-garbage' now has a flag `--invert' which will print all
      paths that should *not* be garbage collected.

    * Do not set LD_LIBRARY_PATH; it breaks many things.  E.g., SuSE's ssh
      dynamically links against libdb4 (?!), due to LD_LIBRARY_PATH it picks
      up our libdb4 instead of SuSE's libdb4, but our libdb4 uses another
      glibc so loading barfs.

      Instead, all packages should use rpaths to store library locations in
      executables/libraries.  The disadvantage is that overriding rpaths is
      harder.  (It is possible by invoking the dynamic linker directly, e.g.,
      `/lib/ld-linux.so.2 --ignore-path LIST program args...' to ignore the
      rpath for the libraries in LIST).  It would be better to use DT_RUNPATH,
      which is consulted by the dynamic linker *after* LD_LIBRARY_PATH but
      *before* ld.so.cache and the system directories.

    * Substitutes now should produce a path with the same id as they are
      substituting for (obvious, really).

    * For greater efficiency, nix-pull/unnar will place the output in a
      path that is probably the same as what is actually needed, thus
      preventing a path copy.

    * Even if a output id is given in a Fix package expression, ensure
      that the resulting Nix derive expression has a different id.  This
      is because Nix expressions that are semantically equivalent (i.e.,
      build the same result) might be different w.r.t. efficiency or
      divergence.  It is absolutely vital for the substitute mechanism
      that such expressions are not used interchangeably.

    * The write() system call can write less than the requested
      number of bytes, e.g., in case of a signal like SIGSTOP.
      This caused `nix --dump' to fail sometimes.

      Note that this bug went unnoticed because the call to `nix
      --dump' is in a pipeline, and the shell ignores non-zero
      exit codes from all but the last element in the pipeline.
      Is there any way to check the result of the initial elements
      in the pipeline?  (In other words, is it at all possible to
      write reliable shell scripts?)

    * A command to register successor fstate expressions.

      Unifying substitutes and successors isn't very feasible for now,
      since substitutes are only used when no path with a certain is
      known.  Therefore, a normal form of some expression stored as a
      substitute would not be used unless the expression itself was
      missing.

commit 1d1c3691d2fdf5aad0baceadd8596f23c1e0e1fa
Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Thu Jul 10 15:11:48 2003 +0000

    * The policy-free derivate sharing now *almost* works. :-)  For any
      hash for which no local expansion is available, Nix can execute a
      `substitute' which should produce a path with such a hash.

      This is policy-free since Nix does not in any way specify how the
      substitute should work, i.e., it's an arbitrary (unnormalised)
      fstate expression.  For example, `nix-pull' registers substitutes
      that fetch Nix archives from the network (through `wget') and unpack
      them, but any other method is possible as well.  This is an
      improvement over the old Nix sharing scheme, which had a policy
      (fetching through `wget') built in.

      The sharing scheme doesn't work completely yet because successors
      from fstate rewriting have to be registered on the receiving side.
      Probably the whole successor stuff can be folded up into the
      substitute mechanism; this would be a nice simplification.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Sun May 25 22:42:19 2003 +0000

    * Prebuilt package sharing.  We allow transparent binary deployment by
      sharing package directories (i.e., the result of building a Nix
      descriptor).

      `nix-pull-prebuilts' obtains a list of all known prebuilts by
      consulting the paths and URLs specified in
      $prefix/etc/nix/prebuilts.conf.  The mappings ($pkghash,
      $prebuilthash) and ($prebuilthash, $location) are registered with
      Nix so that it can use the prebuilt with hash $prebuilthash when
      installing a package with hash $pkghash by downloading and unpacking
      $location.

      `nix-push-prebuilts' creates prebuilts for all packages for which no
      prebuilt is known to exist.  It can then optionally upload these
      to the network through rsync.

      `nix-[pull|push]-prebuilts' just provide a policy.  Nix provides the
      mechanism through the `nix [export|regprebuilt|regurl]' commands.

Author: Eelco Dolstra <e.dolstra@tudelft.nl>
Date:   Fri Apr 25 15:33:50 2003 +0000

    * Cleaned up the semantics of Fix expressions.

    * Conditionals and variables in Fix expressions.  This allows, e.g.,

        Descr(
        [ Bind("pkgId", "subversion-0.21.0")

        , Bind("httpsClient", Bool(True))
        , Bind("httpServer", Bool(True))

        , Bind("ssl", If(Var("httpsClient"), Fix("./openssl-0.9.7b.fix"), ""))

        , Bind("httpd", If(Var("httpServer"), Fix("./httpd-2.0.45.fix"), ""))
        ...
        ])

      which introduces domain feature variables httpsClient and httpServer
      (i.e., whether Subversion is built with https client and webdav
      server support); the values of the variables influences package
      dependencies and the build scripts.

      The next step is to allow that packages can express constraints on
      each other.  E.g., StrategoXT is dependent on an ATerm library with
      the "gcc" variant enabled.  In fact, this may cause several
      Nix instantiations to be created from a single Fix descriptor.  If
      possible, Fix should try to find the least set of instantiations
      that obeys the constraints.

    * A garbage collector for installed packages.  nix-collect-garbage
      doesn't actually delete any packages, it just prints their
      descriptor hashes.  So we can do

        nix info $(nix-collect-garbage)

      to print out the ids of the packages that would be deleted, and

        nix delpkg $(nix-collect-garbage)

      to actually delete them.

    * When we activate a descriptor in nix-switch, remember its hash.
      This allows us to find out all `live' packages on the system by
      doing

        nix closure $(cat /nix/var/nix/links/*.hash)

      which will print out the activated configurations and all packages
      referenced by them.  We could then garbage collect unused packages
      by deleting the difference between `nix listinst' and the set
      returned by `nix closure ...'.

    * In `fix --instantiate', only print out the hashes of the Nix
      descriptors generated out of Fix descriptors specified on the
      command line.  This allows us to say:

    * We no longer use nix-populate standalone, rather we use it as a
      build action for `system' packages (like system.fix) that have
      dependencies on all packages we want to activate.

      So the command sequence to switch to a new activation configuration
      of the system would be:

        $ fix -i .../fixdescriptors/system.fix
        ...
        system.fix -> 89cf4713b37cc66989304abeb9ea189f

        $ nix-switch 89cf4713b37cc66989304abeb9ea189f

    * Added a script nix-activate which builds a list of "activated"
      packages (i.e., the packages that should appear in the user's $PATH,
      and so on).  Based on this list, the script nix-populate creates a
      hierarchy of symlinks to the relevant files in those packages (e.g.,
      for pkg/bin and pkg/lib).

      A nice property of nix-populate is that on each run it creates a
      *new* tree, rather than updating the old one.  It then atomically
      switches over to the new tree.  This allows atomic upgrades or
      rollbacks on the set of activated packages.

    * Command `nix ensure' which is like `nix getpkg' except that if the

      there.
    * Command `nix closure' to print out the closure of the set of
      descriptors under the import relation, starting at a set of roots.
      This can be used for garbage collection (e.g., given a list of
      `activated' packages, we can delete all packages not reachable from
      those).
    * Command `nix graph' to print out a Dot graph of the dependency
      graph.
    * `nix-addroot' adds a root for the (unimplemented) garbage collector.

    * A descriptor for running the Pan newsreader.
    * Added descriptors for gtkspell and its support package pspell.
      Gtkspell is an optional dependency of Pan, so we should add the
      ability to nix-instantiate to instantiate variants of a package
      based on a selection of features.

    * A command to run programs in Nix packages, that is, to execute a run
      action.  Run actions are described by uniquely hashed descriptors,
      just like build actions.  Therefore run actions can have
      dependencies, but these need not be the same as the build time
      dependencies (e.g., at runtime we can link against a different
      version of a dynamic library).  Example:

        nix run 31d6bf4c171282367065e0deecd7c579

      will run the Pan 0.13.91 newsreader with gtkspell support.

    * Descriptor templates for the Pan newsreader and all its
      dependencies.

    * nix-instantiate now instantiantes the closure of the set of
      descriptor templates under the import relation.  I.e., we can now
      say:

        nix-instantiate outdir foo.nix

      which will create descriptors for foo.nix and all imported packages
      in outdir/.

    * Improved Nix.  Resources (package descriptors and other source
      files) are now referenced using their cryptographic hashes.

      This ensures that if two package descriptors have the same contents,
      then they describe the same package.  This property is not as
      trivial as it sounds: generally import relations cause this property
      not to hold w.r.t. temporality.  But since imports also use hashes
      to reference other packages, equality follows by induction.
