* base: Call 'child-cleanup' when 'select' returns an empty set.Ludovic Courtès2020-02-271-14/+26
| | | | | | | | Previously, on Guile >= 2.2, we'd lose this opportunity to call 'child-cleanup', possibly leaving zombies behind us. * src/mcron/base.scm (run-job-loop): Define 'select*'. Don't expect 'select*' to throw upon EINTR or EAGAIN.
* base: Box 'number-children'Mathieu Lirzin2018-03-241-6/+15
| | | | | | | | | * src/mcron/base.scm (number-children): Box it using SRFI-111 to be explicit about the mutability of this object. (update-number-children!): New procedure. (run-job, child-cleanup): Use it. * tests/base.scm ("update-number-children!: 1+") ("number-children: init", "update-number-children!: 1-"): New tests.
* base: Rewrite 'child-cleanup'Mathieu Lirzin2018-03-241-6/+6
| | | | * src/mcron/base.scm (child-cleanup): Use recursion instead of 'do'.
* utils: Add 'get-user'Mathieu Lirzin2018-03-241-3/+2
| | | | | | * src/mcron/utils.scm (get-user): New procedure. * src/mcron/job-specifier.scm (job): Use it. * src/mcron/base.scm (remove-user-jobs): Likewise.
* base: Rewrite 'find-next-jobs' docstring.Mathieu Lirzin2018-03-241-15/+4
| | | | | * src/mcron/base.scm (find-next-jobs): Don't explain the detail of implementation in the docstring.
* base: Add '<schedule>' record data typeMathieu Lirzin2018-03-241-66/+77
| | | | | | | | | | | | | | | | | | Reifying the notion of a schedule helps reasoning about the code. Passing a schedule as an argument to related procedures allows writing simpler unit tests. * src/mcron/base.scm(<schedule>): New record data type. (make-schedule, schedule-user, set-schedule-user!) (schedule-system, set-schedule-system!) (schedule-current, set-schedule-current!): New procedures. (system-job-list, user-job-list, configuration-source): Replace those global variables with ... (%global-schedule): ... this global <schedule> instance. * src/mcron/base.scm (use-system-job-list, use-user-job-list) (remove-user-jobs, clear-system-jobs, add-job, find-next-jobs) (display-schedule, run-job-loop): Add '#:SCHEDULE' keyword argument. * doc/mcron.texi (The base module): Update documentation.
* base: Add 'display-schedule' procedureMathieu Lirzin2018-03-161-27/+19
| | | | | | | | | | | | | This procedure is a more generic and less coupled version of 'get-schedule' which has been kept for backward compatibility and deprecated. * src/mcron/base.scm (display-schedule): New procedure. (get-schedule): Move to ... * src/mcron/core.scm: ... here. * src/mcron/scripts/cron.scm (main): Use 'display-schedule'. * src/mcron/scripts/mcron.scm (main): Likewise. * doc/mcron.texi (The base module): Document it.
* base: Add 'run-job' procedure.Mathieu Lirzin2017-09-281-31/+20
| | | | | | * src/mcron/base.scm (run-jobs): Delete. (run-job): New procedure. (run-job-loop): Use it.
* base: find-next-jobs: Use functional style.Mathieu Lirzin2016-12-281-40/+29
| | | | | * src/mcron/base.scm (find-next-jobs): Rewrite it using functional style. Add docstring.
* all: Gather module imports.Mathieu Lirzin2016-12-281-16/+12
| | | | | | | * src/mcron/base.scm: Gather module imports. * src/mcron/redirect.scm: Likewise. * src/mcron/vixie-specification.scm: Likewise. * src/mcron/vixie-time.scm: Likewise.
* maint: Reformat copyright notices and copying permission statements.Mathieu Lirzin2016-12-281-20/+19

* base: Rewrite 'run-job-loop'.Mathieu Lirzin2016-12-281-44/+33
| | | | | * src/mcron/base.scm (run-job-loop): Use #:optional keyword argument, and 'match'.
* base: run-jobs: Ensure that the child process always terminates.Ludovic Courtès2016-05-071-7/+11
| | | | * src/mcron/base.scm (run-jobs): Use 'dynamic-wind' instead of 'begin'.
* base: Rename (mcron core) module to (mcron base).Mathieu Lirzin2016-05-071-0/+270
The 'configure' script deletes the 'core.*' files. Having a file named 'base.scm' instead of 'core.scm' simplifies the build process without changing the semantics. * src/mcron/mcron-core.scm: Rename to ... * src/mcron/base.scm: ... this. All module users changed. * Makefile.am (MODULES): Add 'src/mcron/base.scm'. (CP): Remove variable. (src/mcron/core.scm): Remove target. (GEN_MODULES): Remove 'src/mcron/core.scm'. (dist_mcronmodule_DATA): Remove 'src/mcron/mcron-core.scm' * doc/mcron.texi: Adapt to name change. * .gitignore: Update.
