nly 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. Signed-off-by: Maxim Cournoyer <maxim.cournoyer@gmail.com> Modified-by: Maxim Cournoyer <maxim.cournoyer@gmail.com> Brian Cully 2023-08-20services: Define 'for-home'....* gnu/services.scm (remove-service-extensions): New procedure. (for-home?): New syntax parameter. (for-home): New macro. Ludovic Courtès 2023-06-06services: Check if service is #f before applying clause....* gnu/services.scm (apply-clauses): Check if service is #f before trying to apply clause. Follow up of 181951207339508789b28ba7cb914f983319920f. Josselin Poiret 2023-06-06services: 'modify-services' preserves service ordering....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. Ludovic Courtès 2023-06-02services: Error in MODIFY-SERVICES when services don't exist...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> Brian Cully 2023-05-16services: Add default values....* gnu/services.scm (boot-service-type, activation-service-type, etc-service-type, profile-service-type): Add default-value. * gnu/system/shadow.scm (account-service-type): Add default-value. Andrew Tropin 2023-03-16services: etc-service: Deprecate etc-service procedure....* gnu/services.scm (etc-service): Deprecate procedure. * gnu/system.scm (operating-system-etc-service): Replace etc-service with etc-service-type. Signed-off-by: Ludovic Courtès <ludo@gnu.org> Bruno Victal 2022-08-30services: provenance: Use 'current-channels' to obtain provenance data....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'. Ludovic Courtès 2022-05-29gnu: services: Update setuid service description....* gnu/services.scm (setuid-program-service-type)[description]: Remove ‘root’, add ‘setgid’. Tobias Geerinckx-Rice 2022-05-18services: Make <service-type> 'description' field mandatory....* gnu/services.scm (<service-type>)[description]: Remove default value. * tests/services.scm: Add 'description' field to each 'service-type' form. Ludovic Courtès 2022-05-18services: Add more description fields....* gnu/services.scm (simple-service): Add 'description' field. * gnu/services/base.scm (udev-rules-service): Likewise. * gnu/system/install.scm (configuration-template-service-type): Likewise. * gnu/tests.scm (marionette-service-type): Likewise.
