8 daysservices: shepherd: Support “free-form” services.Ludovic Courtès
* gnu/services/shepherd.scm (<shepherd-service>)[free-form]: New field. [start]: Add default value. (shepherd-service-file): Rename to… (shepherd-service-file/regular): … this. (shepherd-service-file/free-form): New procedure. (shepherd-service-file): Dispatch to one of the two procedures above. * doc/guix.texi (Shepherd Services): Document the ‘free-form’ field.

2024-05-25services: shepherd: Failure to load a service does not prevent booting.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/71144>. Fixes a bug whereby, when loading a service file would fail, for instance due to an unbound variable, a REPL would be opened on the console, preventing the system from booting. This fixes that by isolating service load errors and making them non-fatal. * gnu/services/shepherd.scm (shepherd-configuration-file)[config]: Remove call to ‘call-with-error-handling’. Use ‘filter-map’ instead of ‘map’ to iterate over service files, and catch exceptions raised by ‘load-compiled’. Change-Id: Ie6e76ea514837f85386232f797bc77b2882b5c22
2024-03-21services: shepherd: Load each service file in a fresh module.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/67649>. * gnu/home/services/shepherd.scm (home-shepherd-configuration-file)[config]: Define ‘make-user-module’. Call ‘load’ in ‘save-module-excursion’. * gnu/services/shepherd.scm (shepherd-configuration-file): Likewise. Reported-by: Attila Lendvai <attila@lendvai.name> Change-Id: I7df11c81b5bbbf2b24a8daa02502a000e0826fe0
2024-01-28services: shepherd: Add respawn-limit and respawn-delay.Attila Lendvai
* gnu/services/shepherd.scm (<shepherd-service>): Add respawn-limit and respawn-delay. (shepherd-service-file): Emit the two values into the shepherd service constructor form. Change-Id: I54408e8fb4bcc0956d9610771bf5c566fdc2914c Signed-off-by: Ludovic Courtès <ludo@gnu.org>
2024-01-08services: shepherd: Use the 0.10.x GOOPS-less interface.Ludovic Courtès
* gnu/services/shepherd.scm (%default-modules): Remove (oop goops). (shepherd-service-file): Use (service …) instead of (make <service> …). Use ‘actions’ instead of ‘make-actions’. (scm->go): Remove use of (oop goops). (shepherd-configuration-file): Pass ‘register-services’ a list. Use ‘start-in-the-background’ unconditionally.

2024-01-05services: shepherd: Remove ‘dynamic-wind’ in ‘call-with-*-file’.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/64653>. The ‘dynamic-wind’ was causing files to be closed prematurely when leaving the dynamic extent of PROC for instance via a delimited continuation, using Fibers (that ‘dynamic-wind’ call was also semantically incorrect in the first place). * gnu/services/shepherd.scm (shepherd-configuration-file) [config](call-with-file): Remove. (call-with-input-file, call-with-output-file): Rewrite in terms of ‘call-with-port’. Change-Id: Ica8af71a04f525a15be99985552063cb98cd6ee8

2023-05-13services: shepherd: Default to 0.10.Ludovic Courtès

* gnu/services/shepherd.scm (shepherd-configuration-action): New * doc/guix.texi (Shepherd Services): Document it.
2022-09-29services: shepherd: Leave the finalization thread in peace.Ludovic Courtès
This gets rid of that (in)famous at boot time: error in finalization thread: Success This was caused by the file-descriptor closing loop, which would clause the finalization pipe, leading the finalization thread to (erroneously) error out. Thanks to Josselin Poiret for locating the problem! * gnu/services/shepherd.scm (shepherd-boot-gexp): In 'loop', replace 'close-fdes' with a pair of 'fcntl' calls to add FD_CLOEXEC.
2022-09-13services: shepherd: Install O_CLOEXEC variant of 'call-with-input-file' & co.Ludovic Courtès
Fixes a bug introduced with the Shepherd 0.9.2 upgrade in commit 1ba0e38267c9ff8bb476285091be6e297bbf136e whereby files opened by, say, the 'start' method of 'urandom-seed', could leak into the execution environment of some other service--e.g., 'term-tty4'. * gnu/services/shepherd.scm (shepherd-configuration-file)[config]: Override 'call-with-input-file' and 'call-with-output-file'.
2022-09-11services: shepherd: Open /dev/null as O_CLOEXEC.Ludovic Courtès
Failing to do that, that file descriptor could be inherited by child processes as of Shepherd 0.9.2. * gnu/services/shepherd.scm (shepherd-configuration-file): Open /dev/null as O_CLOEXEC.
2022-04-10services: shepherd: Do not unload transient services.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/54812>. Starting with Shepherd 0.9.0 and the use of 'make-inetd-constructor' in commit 808b9e850491c7b1d867a5f1f4d5ee6f61f345d4, systems might be running transient Shepherd services such as those corresponding to SSH connections. Before this change, 'shepherd-service-upgrade' would have those transient services in the list of services to unload; concretely, that would lead all SSH connections to be closed upon 'guix system reconfigure'. * gnu/services/shepherd.scm (shepherd-service-upgrade): Remove transient services to TO-UNLOAD.
2022-04-07services: shepherd: Default to version 0.9.Ludovic Courtès

2020-04-15services: shepherd: Increase the PID file timeout to 30s.Ludovic Courtès
