| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before that '.log' files for scheme tests were fragmented and not included in test-suite.log.

(SCM_LOG_COMPILER, AM_SCM_LOG_FLAGS): Delete variables.

* utils: Use '@' for separating package names and version numbers.Mathieu Lirzin2016-03-02
| | | | | | | | | | | | | | | | | | | | | This provides the ability to use numbers in package names. Fixes <http://bugs.gnu.org/19219>. * guix/utils.scm (package-name->name+version): New procedure. * gnu/packages.scm (%find-package): Add a FALLBACK? keyword argument. Use the previous method when no package is found. (specification->package+output, specification->package): Adapt documentation to new syntax. * doc/guix.texi (Invoking guix package, Invoking guix import): Likewise. * guix/ui.scm (package-specification->name+version+output): Likewise. * guix/scripts/import/hackage.scm (show-help): Likewise. * tests/guix-build.sh: Adapt to new syntax. * tests/guix-lint.sh: Likewise. * tests/guix-package.sh: Likewise. * tests/ui.scm ("package-specification->name+version+output"): Likewise. * tests/utils.scm ("package-name->name+version"): Likewise. * NEWS: Mention new syntax.
* utils: Add 'ensure-keyword-arguments'.Ludovic Courtès2016-01-06
| | | | | * guix/utils.scm (delkw, ensure-keyword-arguments): New procedures. * tests/utils.scm ("ensure-keyword-arguments"): New test.

* guix: utils: Add fold-tree and fold-tree-leaves.Eric Bavier2014-07-20
| | | | | * guix/utils.scm (fold-tree, fold-tree-leaves): New functions. * tests/utils.scm: Add tests for them.
* offload: '{send,receive}-files' wait for completion of the transfer.Ludovic Courtès2014-04-14
| | | | | | | | | | | | | | | | | | Fixes situations where the remote 'guix build' is invoked before the .drv has been completely copied, as reported at <https://lists.gnu.org/archive/html/guix-devel/2014-04/msg00174.html>. In some cases 'send-files' would return before the other end is done importing the files, and so the subsequent 'guix build' invocation would just miss the .drv file it refers to. * guix/utils.scm (call-with-decompressed-port): Don't close PORT. (call-with-compressed-output-port): Likewise. * tests/utils.scm ("compressed-output-port + decompressed-port"): Adjust accordingly. * guix/scripts/offload.scm (send-files): Add explicit (close-pipe pipe) call. (retrieve-files): Likewise.
* tests: Avoid buffering in 'fcntl-flock' tests.Ludovic Courtès2014-04-07
| | | | | | | Partially fixes <http://bugs.gnu.org/17212>. * tests/utils.scm ("fcntl-flock wait", "fcntl-flock non-blocking"): Open files in binary mode, with no buffering.
* utils: Add 'call-with-decompressed-port' and 'call-with-compressed-output-port'.Ludovic Courtès2014-03-24
| | | | | | | * guix/utils.scm (call-with-decompressed-port, call-with-compressed-output-port): New procedures. * tests/utils.scm ("compressed-output-port + decompressed-port"): Rewrite to use them.
* utils: Add 'filtered-output-port' and 'compressed-output-port'.Ludovic Courtès2014-03-24
| | | | | | | * guix/utils.scm (filtered-output-port, compressed-output-port): New procedures. * tests/utils.scm ("compressed-output-port + decompressed-port"): New test.
* utils: Add 'decompressed-port' and 'compressed-port'.Ludovic Courtès2014-03-22
| | | | | | | | | * guix/utils.scm (decompressed-port, compressed-port): New procedures. * guix/scripts/substitute-binary.scm (decompressed-port): Remove. (guix-substitute-binary): Pass a symbol or #f as the first argument to 'decompress-port'. * tests/utils.scm ("compressed-port, decompressed-port, non-file"): New test.
* utils: 'filtered-port' doesn't leave dangling processes behind.Ludovic Courtès2014-03-22
| | | | | | | * guix/utils.scm (filtered-port): Make sure the 'execl' child process always exits, and does (primitive-_exit 1) upon execution failure. Use 'primitive-_exit' in the 'dump-port' child process. * tests/utils.scm ("filtered-port, does not exist"): New test.
* utils: Add a non-blocking option for 'fcntl-flock'.Ludovic Courtès2014-03-08
| | | | | | * guix/utils.scm (F_SETLK): New variable. (fcntl-flock): Add 'wait?' keyword parameter; honor it. * tests/utils.scm ("fcntl-flock non-blocking"): New test.
* tests: Rewrite 'fcntl-lock' test.Ludovic Courtès2014-03-06
| | | | | | | | | * tests/utils.scm (temp-file): New variable. ("fcntl-flock"): Rewrite to actually test whether the child process waits for the lock to be released. The previous test was wrong because (1) it expected F_SETLK semantics, not F_SETLKW, and (2) it got EBADF because of a mismatch between the open mode and the lock style.
* utils: Add 'fcntl-flock'.Ludovic Courtès2014-01-24
| | | | | | * guix/utils.scm (%struct-flock, F_SETLKW, F_xxLCK): New variables. (fcntl-flock): New procedure. * tests/utils.scm ("fcntl-flock"): New test.
* utils: Add 'string-replace-substring'.Ludovic Courtès2013-11-13
| | | | | | * guix/utils.scm (string-replace-substring): New procedure. Based on code by Mark H. Weaver. * tests/utils.scm ("string-replace-substring"): New test.
* utils: Add `guile-version>?', and use it.Ludovic Courtès2013-08-23
| | | | | | | | | | | | | | This fixes Guile version comparisons when (version) has a vendor-specific suffix. Reported by Andreas Enge <andreas@enge.fr>. * guix/utils.scm (guile-version>?): New procedure. * tests/utils.scm ("guile-version>? 1.8", "guile-version>? 10.5"): New tests. * guix/scripts/substitute-binary.scm (fetch, progress-report-port): Use `guile-version>?' instead of `version>?'. * guix/http-client.scm (when-guile<=2.0.5, http-fetch): Likewise.
* substitute-binary: Try hard to avoid port buffering.Ludovic Courtès2013-08-22
| | | | | | | | | * guix/scripts/substitute-binary.scm (fetch): In the `file' case, open with the `b' flag, so that the coding cookie reading thing doesn't lead to buffering some of the data (on 2.0.5). * tests/utils.scm ("filtered-port, file"): Open with `r0b'. Fixes a test failure with Guile 2.0.5 whereby the first byte of FILE would be missing from DECOMPRESSED.
* substitute-binary: Pass `filtered-port' an unbuffered port.Ludovic Courtès2013-05-15
| | | | | | | | | | | | | | | | | | This fixes a bug whereby `read-response' would read more than just the response, with the extra data going into the port's buffer; the "bzip2 -dc" process spawned by `filtered-port' would not see the those buffered data, which are definitely lost, and would bail out with "bzip2: (stdin) is not a bzip2 file." * guix/utils.scm (filtered-port): Document that INPUT must be unbuffered. * guix/web.scm (http-fetch): Add `buffered?' parameter. Call `open-socket-for-uri' explicitly, and call `setvbuf' when BUFFERED? is false. Pass the port to `http-get'. Close it upon 301/302. * guix/scripts/substitute-binary.scm (fetch): Add `buffered?' parameter. Pass it to `http-fetch'; honor it for `file' URIs. (guix-substitute-binary): Call `fetch' with #:buffered? #f for port RAW. * tests/utils.scm ("filtered-port, file"): Open FILE as unbuffered.
* Move record utilities to (guix records).Ludovic Courtès2013-05-12
| | | | | | | | | | | | | | | | * guix/utils.scm (define-record-type*): Move to... * guix/records.scm: ... here. New file. * guix/build-system.scm, guix/packages.scm: Use it. * guix/gnu-maintenance.scm: Likewise. (official-gnu-packages)[alist->record]: Remove. * guix/scripts/substitute-binary.scm: Likewise. (alist->record, object->fields): Remove. * tests/utils.scm ("define-record-type*", "define-record-type* with letrec* behavior", "define-record-type* & inherit", "define-record-type* & inherit & letrec* behavior", "define-record-type* & thunked", "define-record-type* & thunked & default", "define-record-type* & thunked & inherited"): Move to... * tests/records.scm: ... here.
