2023-08-31gnu: services: Revert to deleting and updating all matching servicesBrian Cully
This patch reverts the behavior introduced in 181951207339508789b28ba7cb914f983319920f which caused ‘modify-services’ clauses to only match a single instance of a service. We will now match all service instances when doing a deletion or update, while still raising an exception when trying to match against a service that does not exist in the services list, or which was deleted explicitly by a ‘delete’ clause (or an update clause that returns ‘#f’ for the service). Fixes: #64106 * gnu/services.scm (%modify-services): New procedure. (modify-services): Use it. (apply-clauses): Add DELETED-SERVICES argument, change to modify one service at a time. * tests/services.scm ("modify-services: delete then modify") ("modify-services: modify then delete") ("modify-services: delete multiple services of the same type") ("modify-services: modify multiple services of the same type"): New tests.

2023-08-20services: Define 'for-home'.Ludovic Courtès
* gnu/services.scm (remove-service-extensions): New procedure. (for-home?): New syntax parameter. (for-home): New macro.
2023-06-06services: Check if service is #f before applying clause.Josselin Poiret
* gnu/services.scm (apply-clauses): Check if service is #f before trying to apply clause. Follow up of 181951207339508789b28ba7cb914f983319920f.
2023-06-06services: 'modify-services' preserves service ordering.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/63921>. The regression was introduced in dbbc7e946131ba257728f1d05b96c4339b7ee88b, which changed the order of services. As a result, someone using 'modify-services' could find themselves with incorrect ordering of expressions in the "boot" script, whereby the cleanup expressions would come after (execl ".../shepherd"). This, in turn, would lead shepherd to error out at boot with EADDRINUSE on /var/run/shepherd/socket. * gnu/services.scm (%delete-service, %apply-clauses): Remove. (clause-alist): New macro. (apply-clauses): New procedure. (modify-services): Use it. Adjust docstring. * tests/services.scm ("modify-services: do nothing"): Remove 'sort' call. ("modify-services: delete service"): Likewise, and add 't4' service. ("modify-services: change value"): Remove 'sort' call and fix expected value.
2023-06-02services: Error in MODIFY-SERVICES when services don't existBrian Cully
This patch causes MODIFY-SERVICES to raise an error if a reference is made to a service which isn't in its service list. This it to help users notice if they have an invalid rule, which is currently silently ignored. * gnu/services.scm (%delete-service): new procedure (%apply-clauses): new syntax rule (%modify-service): remove syntax rule Signed-off-by: Ludovic Courtès <ludo@gnu.org>

2022-08-30services: provenance: Use 'current-channels' to obtain provenance data.Ludovic Courtès
Previously, build-time metadata from (guix config) would be ignored when available--e.g., when running /run/current-system/profile/bin/guix. This is a followup to 316fc2acbb112bfa572ae30f95a93bcd56621234. * gnu/services.scm (provenance-entry): Use 'current-channels' instead of 'current-profile' + 'profile-channels'.

2021-08-12system: Handle 'setuid-programs' deprecation handling as a field sanitizer.Ludovic Courtès
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'.

2020-10-16services: provenance: Wrap config file name in 'assume-valid-file-name'.Ludovic Courtès

2020-08-25Remove "guile-zlib" extension when unused.Mathieu Othacehe
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.
2020-08-25linux-libre: Support module compression.Mathieu Othacehe
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.

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.

2019-11-09services: 'fold-services' memoizes service values.Ludovic Courtès
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.
2019-08-14remote: Remove '--system' argument.Jakob L. Kreuze

Fixes a bug whereby services indirectly depended on would not be automatically instantiated. * gnu/services.scm (instantiate-missing-services): Loop back when the length of ADJUSTED is greater than that of INSTANCES. * tests/services.scm ("instantiate-missing-services, indirect"): New test.
2018-06-20services: boot: Take gexps instead of monadic gexps.Ludovic Courtès

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'.
