| * | base: Annotate output with job information....Before this change, it was difficult to discern which job emitted which
output, as there was no information connecting the job to the output it
produced. This change rectifies that by annotating each line output by
cron/mcron with a prefix that contains a timestamp and the job name. It also
reports about when the job runs and whether it completed successfully or
failed. It was initially suggested here: <https://issues.guix.gnu.org/36510>.
Thanks to the fine people from the #guile libera.chat IRC channel for
providing ideas and help; this change would not have been possible without
them!
* src/mcron/base.scm (install-suspendable-ports!): Install suspendable ports.
(%date-format, %log-format): New parameters.
(validate-date-format, validate-log-format): New procedures.
(<job-data>): New record.
(run-job): Update doc. Redirect stdout and stderr to a pipe. Return a
<job-data> instance containing the input port and other information about the
job. Output job status messages.
(process-output): New procedure.
(child-cleanup): Add docstring. Use positive logic. Call 'process-output'
one last time after a child process is collected.
(run-job-loop): Add a CHILDREN-DATA variable to the loop. Provide the open
file descriptors of the children ports to select*, and collect their output
when they trigger select.
* tests/base.scm ("run-job: basic"): Adjust and fix indentation.
(dummy-job/capture-output): New procedure.
("run-job, output"): New test.
("validate-date-format, valid", "validate-date-format, invalid")
("validate-log-format, valid", "validate-log-format, invalid")

("run-job, failure in shell action"): New tests.
* src/mcron/scripts/cron.scm (show-help): Document new options.
(%options) [log-format, date-format]: New options.
(main): Parameterize the main loop with the new parameter options (or their
default values when not provided); move exception handling elsewhere (see
below).
* src/mcron/scripts/mcron.scm: Likewise.
* src/cron.in: Install error handler here.
* src/mcron.in: Likewise.
* doc/mcron.texi: Document new cron and mcron options, as well as new
(mcron base) APIs.

| * | Revert "Minor cosmetic simplification of case logic after previous patch."...This reverts commit 99a26e5de6d132056999074ce4f4f2cf24ec8c2f.

| * | Minor cosmetic simplification of case logic after previous patch.... * src/mcron/base.scm: change around some /cond/s and /if/s.
| Dale Mellor | 2021-12-30 | 1 | -25/+25 |
| * | base: Handle nonexistent user home directories....This is useful for running jobs as the "nobody" user, for example.
* src/mcron/base.scm (run-job): Catch the ENOENT (2, "No such file or
directory") error when attempting to change directory to the user home
directory.

| * | project: banish need for C compiler...This patch gets rid of the thin veneer that we currently have around the three
executables. This was done for historical reasons (circa 2003 Guile couldnʼt
deal with process signals and forks). In fact these problems were fixed many
moons ago, and there is now no need for it. The project becomes 100% Guile!
Many files are affected; interested coders should use the GIT repository to
understand the details of all the changes.

| * | base: Avoid 'call-with-current-continuation'....'call-with-current-continuation' is overkill and not quite what we
want. 'let/ec' is supported in Guile 2.0, 2.2, and 3.0.
* src/mcron/base.scm (run-job-loop): Use 'let/ec' instead of
'call-with-current-continuation'.
| Ludovic Courtès | 2020-02-27 | 1 | -22/+22 |
| * | base: Call 'child-cleanup' when 'select' returns an empty set....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.
| Ludovic Courtès | 2020-02-27 | 1 | -14/+26 |
| * | base: Box 'number-children'...* 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.

implementation in the docstring.
| Mathieu Lirzin | 2018-03-24 | 1 | -15/+4 |
| * | base: Add '<schedule>' record data type...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 ...

(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.
| Mathieu Lirzin | 2018-03-24 | 1 | -66/+77 |
| * | base: Add 'display-schedule' procedure...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'.

| * | base: find-next-jobs: Use functional style....* src/mcron/base.scm (find-next-jobs): Rewrite it using functional
style. Add docstring.

| Ludovic Courtès | 2016-05-07 | 1 | -7/+11 |
| * | base: Rename (mcron core) module to (mcron base)....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'.
