*	base: Annotate output with job information.	Maxim Cournoyer	2022-07-07	1	-34/+43
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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, output with custom format", "run-job, failure") ("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. * tests/basic.sh: Test the new options.

*	project: banish need for C compiler	Dale Mellor	2020-04-20	1	-48/+66
\| \| \| \| \| \| \| \| \| \|	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.
*	utils: Remove 'parse-args'	Mathieu Lirzin	2018-03-27	1	-1/+2
\| \| \| \| \| \| \| \|	It seems that it is not useful to catch 'misc-error exception when calling 'getopt-long'. Since 'parse-args' purpose was only to catch this particular error, it can be deleted. * src/mcron/utils.scm (parse-args): Remove.
*	utils: Use 'scandir' instead of custom 'for-each-file'	Mathieu Lirzin	2018-03-20	1	-3/+4
\| \| \| \| \| \| \| \| \| \| \| \|	* src/mcron/utils.scm (for-each-file): Delete. * src/mcron/scripts/cron.scm (process-files-in-system-directory): Use 'scandir' which has the benefit of being deterministic. * src/mcron/scripts/mcron.scm (process-files-in-user-directory): Likewise. * tests/schedule.sh: Update expected output which is now more reliable. * NEWS: Update. Suggested-by: Ludovic Courtès <ludo@gnu.org>
*	base: Add 'display-schedule' procedure	Mathieu Lirzin	2018-03-16	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \|	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.
*	build: Rename (mcron main) to (mcron utils).	Mathieu Lirzin	2016-12-28	1	-1/+1
\| \| \| \| \| \| \| \| \|	* src/mcron/main.scm: Rename to ... * src/mcron/utils.scm: ... this. * src/mcron/scripts/cron.scm: Adapt. * src/mcron/scripts/crontab.scm: Likewise. * src/mcron/scripts/mcron.scm: Likewise. * Makefile.am (dist_mcronmodule_DATA): Likewise.
*	all: Separate programs in different executables.	Mathieu Lirzin	2016-12-01	1	-0/+177
	This improves readability and complies with the GNU Coding Standards by making the behavior of the programs independent of the name used to invoke them. * src/mcron/scripts/cron.scm: New file. * src/mcron/scripts/crontab.scm: Likewise. * src/mcron/scripts/mcron.scm: Likewise. * Makefile.am (dist_mcronmodule_DATA): Remove 'src/mcron/crontab.scm'. (bin_PROGRAMS): Add 'crontab'. (sbin_PROGRAMS): Add 'cron'. (mcron_CFLAGS, mcron_LDADD): Rename to ... (AM_CFLAGS, LDADD): ... these. (cron_SOURCES, cron_CPPFLAGS, cron_DEPENDENCIES) (crontab_SOURCES, crontab_CPPFLAGS, crontab_DEPENDENCIES) (mcron_CPPFLAGS, mcronscriptdir, dist_mcronscript_DATA): New variables. (modules): Redefine it in terms of other '_DATA' variables. * src/mcron/crontab.scm: Remove file. * src/mcron/main.scm (parse-args): New procedure. (command-name, command-type, options): Remove. (show-version): Adapt. (show-help, process-files-in-system-directory, cron-file-descriptors) (main, process-user-file, process-files-in-user-directory): Move procedures in the new files. * src/mcron.c (inner_main): Define the current module at compile time. * TODO: Update. * .gitignore: Likewise.
