* system: Handle 'setuid-programs' deprecation handling as a field sanitizer.Ludovic Courtès2021-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, evaluating an OS configuration with a childhurd (for instance) would produce tens of lines like: guix system: warning: representing setuid programs with '#<file-append #<package shadow@4.8.1 gnu/packages/admin.scm:798 7ff97f6f7640> "/bin/passwd">' is deprecated; use 'setuid-program' instead Now, it prints this one line: gnu/system/hurd.scm:105:2: warning: representing setuid programs with file-like objects is deprecated; use 'setuid-program' instead This change also means that extensions of 'setuid-program-service-type' now have to provide a list of <setuid-program>, so it's stricter in this sense. * gnu/services.scm (setuid-program-file-like-deprecated): Remove. (setuid-program-service-type)[extend]: Remove 'setuid-program-file-like-deprecated' call. Assume CONFIG and EXTENSIONS are already lists of <setuid-program> records. * gnu/system.scm (<operating-system>)[setuid-programs]: Add 'sanitize' property. Change accessor name from '%operating-system-setuid-programs' to 'operating-system-setuid-programs'. (operating-system-default-essential-services) (hurd-default-essential-services): Adjust accordingly. (ensure-setuid-program-list): New macro. (%ensure-setuid-program-list): New procedure, based on 'setuid-program-file-like-deprecated'.

(setuid-program-service-type): Make use of setuid-program->activation-gexp. Adjust the extend property to handle <setuid-program>. * gnu/build/activation.scm (activate-setuid-programs): Update to expect a <setuid-record> list for each program entry. * gnu/system.scm: (operating-system-setuid-programs): Renamed to %operating-system-setuid-programs and replace it with new procedure.

| | | | | | | * gnu/services.scm (%modify-service): Add clause for DELETE syntax. (modify-services): Use FILTER-MAP; adjust docstring. * doc/guix.texi (System Services): Mention alternative syntax. (X Window): Use MODIFY-SERVICES syntax.
* gnu: services: Add activate script to the profile system directory.Brice Waegeneire2021-03-09
| | | | | * gnu/services.scm (activation-profile-entry): New procedure... (activation-service-type): ... use it.
* services: profile: Create manifest at monadic-bind time.Ludovic Courtès2020-12-01
| | | | | | | | Fixes <https://bugs.gnu.org/44952>. Reported by Mathieu Othacehe <othacehe@gnu.org>. * gnu/services.scm (packages->profile-entry): Change 'with-monad' to 'mlet' with one binding.
* services: provenance: Wrap config file name in 'assume-valid-file-name'.Ludovic Courtès2020-10-16
| | | | | | | | This gets rid of a pointless 'local-file' warning when running 'guix system reconfigure FILE' and FILE is a relative file name. * gnu/services.scm (provenance-entry): Wrap CONFIG-FILE in 'assume-valid-file-name'.
* Remove "guile-zlib" extension when unused.Mathieu Othacehe2020-08-25
| | | | | | | | | | | | | | | | This is a follow-up of 755f365b02b42a5d1e8ef3000dadef069553a478. As (zlib) is autoloaded in (gnu build linux-modules), "guile-zlib" is needed as an extension only when it is effectively used. * gnu/installer.scm (installer-program): Remove "guile-zlib" from the extensions. * gnu/machine/ssh.scm (machine-check-initrd-modules): Ditto. * gnu/services.scm (activation-script): Ditto. * gnu/services/base.scm (default-serial-port): Ditto, (agetty-shepherd-service): ditto, (udev-service-type): ditto. * gnu/system/image.scm (gcrypt-sqlite3&co): Ditto. * gnu/system/shadow.scm (account-shepherd-service): Ditto.
* linux-libre: Support module compression.Mathieu Othacehe2020-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for GZIP compression for linux-libre kernel modules. The initrd modules are kept uncompressed as the initrd is already compressed as a whole. The linux-libre kernel also supports XZ compression, but as Guix does not have any available bindings for now, and the compression time is far more significant, GZIP seems to be a better option. * gnu/build/linux-modules.scm (modinfo-section-contents): Use 'call-with-gzip-input-port' to read from a module file using '.gz' extension, (strip-extension): new procedure, (dot-ko): adapt to support compression, (ensure-dot-ko): ditto, (file-name->module-name): ditto, (find-module-file): ditto, (load-linux-module*): ditto, (module-name->file-name/guess): ditto, (module-name-lookup): ditto, (write-module-name-database): ditto, (write-module-alias-database): ditto, (write-module-device-database): ditto. * gnu/installer.scm (installer-program): Add "guile-zlib" to the extensions. * gnu/machine/ssh.scm (machine-check-initrd-modules): Ditto. * gnu/services.scm (activation-script): Ditto. * gnu/services/base.scm (default-serial-port): Ditto, (agetty-shepherd-service): ditto, (udev-service-type): ditto. * gnu/system/image.scm (gcrypt-sqlite3&co): Ditto. * gnu/system/linux-initrd.scm (flat-linux-module-directory): Add "guile-zlib" to the extensions and make sure that the initrd only contains uncompressed module files. * gnu/system/shadow.scm (account-shepherd-service): Add "guile-zlib" to the extensions. * guix/profiles.scm (linux-module-database): Ditto.
* machine: ssh: Check for potential system downgrades.Ludovic Courtès2020-07-27
| | | | | | | | | | | | | | | This is a followup to 8e31736b0a60919cc1bfc5dc22c395b09243484a. * guix/scripts/system/reconfigure.scm (check-forward-update): Add #:current-channels.

* services: Add 'system-provenance' procedure.Ludovic Courtès2020-07-15
| | | | | | | * gnu/services.scm (sexp->channel, system-provenance): New procedures. * guix/scripts/system.scm (sexp->channel): Remove. (display-system-generation): Use 'system-provenance' instead of parsing the "provenance" file right here.
* services: provenance: Save channel introductions.Ludovic Courtès2020-07-01
| | | | | | | | * gnu/services.scm (channel->code): Include CHANNEL's introduction, if any, unless CHANNEL is the singleton %DEFAULT-CHANNELS. (channel->sexp): Add comment. * guix/scripts/system.scm (sexp->channel): Change pattern to allow for extensibility.
* gnu: services: Add %hurd-startup-service.Jan (janneke) Nieuwenhuizen2020-06-08
| | | | | | | | | | | | | | This decouples startup of the Hurd from the "hurd" package, moving the RC script into SYSTEM. * gnu/packages/hurd.scm (hurd)[inputs]: Remove hurd-rc-script. [arguments]: Do not substitute it. Update "runsystem.sh" to parse kernel arguments and exec into --system=SYSTEM/rc. (hurd-rc-script): Move to... * gnu/services.scm (%hurd-rc-file): ...this new variable. (hurd-rc-entry): New procedure. (%hurd-startup-service): Use it in new variable. * gnu/system.scm (hurd-default-essential-services): Use it.
* system: examples: Add bare-hurd.tmpl.Jan (janneke) Nieuwenhuizen2020-06-08
| | | | | | | | * gnu/system/hurd.scm (%hurd-def%hurd-default-operating-system-kernel, %hurd-default-operating-system): New exported variables. * gnu/system/examples/bare-hurd.tmpl: New file. * Makefile.am (EXAMPLES): Add it. * tests/guix-system.sh: Add --target=i586-pc-gnu when testing it.

* services: etc: Detect and report duplicate entries.Ludovic Courtès2020-04-21
| | | | | | | | | Fixes <https://bugs.gnu.org/40729>. Reported by Christopher Baines <mail@cbaines.net>. * gnu/services.scm (files->etc-directory)[assert-no-duplicates]: New procedure. Use it.

* services: Accumulate builds for 'system' entries.Ludovic Courtès2020-04-02
| | | | | | | | That way, more build requests are accumulated when running "guix system build". * gnu/services.scm (system-derivation): Use 'mapm/accumulate-builds' rather than 'sequence'.
* services: Add 'provenance-service-type'.Ludovic Courtès2019-12-07

* services: 'fold-services' memoizes service values.Ludovic Courtès2019-11-09
| | | | | | | | | | | | Previously 'fold-services' could end up traversing the same services in the graph several times, which is what this change addresses. The hit rate on the 'add-data-to-store' cache goves from 9% to 8% on "guix system build desktop.tmpl -nd", and the number of lookups in that cache goes from 4458 to 4383. * gnu/services.scm (fold-services): Turn 'loop' into a monadic procedure in %STATE-MONAD and use it to memoize values of visited services.
* remote: Remove '--system' argument.Jakob L. Kreuze2019-08-14
| | | | | | | | * gnu/services.scm (activation-script): Return a <program-file> rather than a <scheme-file>. * gnu/deploy.scm (guix-deploy): Remove handling for '--system'. (show-help): Remove documentation for '--system'. (%default-options): Remove default setting for 'system'.

* services: boot: Take gexps instead of monadic gexps.Ludovic Courtès2018-06-20
| | | | | | | | | | | | | | | * gnu/services.scm (compute-boot-script): Rename 'mexps' to 'gexps' and remove 'mlet' form. (boot-service-type): Update comment.

| | | | | | * gnu/services.scm (compute-boot-script): Reverse MEXPS. * gnu/system.scm (essential-services): Reverse order of %SHEPHERD-ROOT-SERVICE, %ACTIVATION-SERVICE, and CLEANUP-SERVICE-TYPE.
* discovery: Remove dependency on (guix ui).Ludovic Courtès2018-04-08
| | | | | | | | | | | | | | This reduces the closure of (guix discovery) from 28 to 8 modules. * guix/discovery.scm (scheme-files): Use 'format' instead of 'warning'. (scheme-modules): Add #:warn parameter. Use it instead of 'warn-about-load-error'. (fold-modules): Add #:warn and pass it to 'scheme-modules'. (all-modules): Likewise. * gnu/bootloader.scm (bootloader-modules): Pass #:warn to 'all-modules'. * gnu/packages.scm (fold-packages): Likewise. * gnu/services.scm (all-service-modules): Likewise. * guix/upstream.scm (importer-modules): Likewise.
* gnu: Refactor boot-service-type and activation-service-type.Chris Marusich2018-03-29
| | | | | | | | * gnu/services.scm (boot-service-type) <compose>: Use the "identity" procedure instead of the "append" procedure because it more accurately reflects the intent, which is to simply return the single list of extensions to which fold-services applies the "compose" procedure. (activation-service-type) <compose>: Likewise.
* services: Missing services are automatically instantiated.Ludovic Courtès2018-01-21
| | | | | | | | | | | | | | | | | | | | | | | This simplifies OS configuration: users no longer need to be aware of what a given service depends on. See the discussion at <https://lists.gnu.org/archive/html/guix-devel/2018-01/msg00114.html>. * gnu/services.scm (missing-target-error): New procedure. (service-back-edges): Use it. (instantiate-missing-services): New procedure. * gnu/system.scm (operating-system-services): Call 'instantiate-missing-services'. * tests/services.scm ("instantiate-missing-services") ("instantiate-missing-services, no default value"): New tests. * gnu/services/version-control.scm (cgit-service-type)[extensions]: Add FCGIWRAP-SERVICE-TYPE. * gnu/tests/version-control.scm (%cgit-os): Remove NGINX-SERVICE-TYPE and FCGIWRAP-SERVICE-TYPE instances. * doc/guix.texi (Log Rotation): Remove 'mcron-service-type' in example.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids collisions with '_' when the latter is used as a 'match' pattern for instance. See <https://lists.gnu.org/archive/html/guix-devel/2017-04/msg00464.html>. * guix/ui.scm: Rename '_' to 'G_'. * po/guix/Makevars (XGETTEXT_OPTIONS): Adjust accordingly. * build-aux/compile-all.scm (warnings): Remove 'format'. * gnu/packages.scm, gnu/services.scm, gnu/services/shepherd.scm, gnu/system.scm, gnu/system/shadow.scm, guix/gnupg.scm, guix/http-client.scm, guix/import/cpan.scm, guix/import/elpa.scm, guix/import/pypi.scm, guix/nar.scm, guix/scripts.scm, guix/scripts/archive.scm, guix/scripts/authenticate.scm, guix/scripts/build.scm, guix/scripts/challenge.scm, guix/scripts/container.scm, guix/scripts/container/exec.scm, guix/scripts/copy.scm, guix/scripts/download.scm, guix/scripts/edit.scm, guix/scripts/environment.scm, guix/scripts/gc.scm, guix/scripts/graph.scm, guix/scripts/hash.scm, guix/scripts/import.scm, guix/scripts/import/cpan.scm, guix/scripts/import/cran.scm, guix/scripts/import/crate.scm, guix/scripts/import/elpa.scm, guix/scripts/import/gem.scm, guix/scripts/import/gnu.scm, guix/scripts/import/hackage.scm, guix/scripts/import/nix.scm, guix/scripts/import/pypi.scm, guix/scripts/import/stackage.scm, guix/scripts/lint.scm, guix/scripts/offload.scm, guix/scripts/pack.scm, guix/scripts/package.scm, guix/scripts/perform-download.scm, guix/scripts/publish.scm, guix/scripts/pull.scm, guix/scripts/refresh.scm, guix/scripts/size.scm, guix/scripts/substitute.scm, guix/scripts/system.scm, guix/ssh.scm, guix/upstream.scm: Use 'G_' instead of '_'.
