* project: banish need for C compilerDale Mellor2020-04-205-91/+157
| | | | | | | | | | 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.
* mcron: Look for local files in local directory.Dale Mellor2020-04-201-2/+5
| | | | | | | | | Previously were looking for files listed on the command line in Guile's modules directory. This is a bug-fix; running 'make check' will reveal one less failure than before. * src/mcron/scripts/mcron.scm (process-user-file): use read and eval instead of load.
* utils: It's 2020!Ludovic Courtès2020-02-271-1/+1
| | | | * src/mcron/utils.scm (show-version): Update copyright year.
* base: Avoid 'call-with-current-continuation'.Ludovic Courtès2020-02-271-22/+22
| | | | | | | | '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'.
* 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.
* build: Add '--with-sendmail' configure option宋文武2018-10-071-4/+4
| | | | | | | | | | | | This allows users to configure the Mail Transfert Agent (MTA) of their choice. * configure.ac: Add '--with-sendmail' option. (SENDMAIL): Default to 'sendmail -t'. * NEWS: Announce it. * src/mcron/redirect.scm (with-mail-out): Assume the MTA is reading the message for recipients. * build-aux/guix.scm: Remove 'which' from the native-inputs.
* vixie-time: Refactor 'parse-vixie-time'Mathieu Lirzin2018-04-081-68/+63
| | | | | * src/mcron/vixie-time.scm (parse-vixie-time): Use 'match' to avoid complex 'car' and 'cdr' usage.
* vixie-time: Refactor 'interpolate-weekdays'Mathieu Lirzin2018-04-081-18/+11
| | | | | * src/mcron/vixie-time.scm (interpolate-weekdays): Avoid mutation and add 'range-wday' inner procedure.
* vixie-time: Adapt to '%find-best-next' possible infinite resultMathieu Lirzin2018-04-011-10/+13
| | | | | | | This is a follow up to commit ae6deb8ea23570c02a7b575a53bba37048aab59f. * src/mcron/vixie-time.scm (increment-time-component): Check if '%find-best-next' returns '+inf.0' not 9999.
* utils: Remove 'parse-args'Mathieu Lirzin2018-03-273-13/+5
| | | | | | | | 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.
* job-specifier: Box 'configuration-user' global variableMathieu Lirzin2018-03-271-6/+4
| | | | | | | | | | | * src/mcron/job-specifier.scm (configuration-user): Box it using SRFI-111 to be explicit about the mutability of this object. (job): Adapt. (set-configuration-user): Adapt and use 'get-user'. * tests/job-specifier.scm ("set-configuration-user: passwd entry") ("set-configuration-user: invalid uid", "set-configuration-user: uid") ("set-configuration-user: invalid spec") ("set-configuration-user: name"): New tests.
* job-specifier: Fix typo "implement" => "implementation"Mathieu Lirzin2018-03-271-1/+2
| | | | * src/mcron/job-specifier.scm (%find-best-next): Fix typo.
* job-specifier: Adapt 'bump-time' to 'next-...-from' proceduresMathieu Lirzin2018-03-261-15/+9
| | | | | | | | | | | | | | | This is a follow-up to commit 913e3c65e4f56476e8ac69f4892cf92c125751ec. Since 'next-...-from' procedures now uses an '#:optional' argument instead of a dotted optional arguments list, 'bump-time' doesn't need to unwrap VALUE-LIST anymore. * src/mcron/job-specifier.scm (bump-time): Pass VALUE-LIST directly to '%find-best-next'. * tests/job-specifier.scm ("next-hour-from"): New test. * NEWS: Update. Reported-by: Ludovic Courtès <ludo@gnu.org>
* job-specifier: Preserve '%find-best-next' arguments exactnessMathieu Lirzin2018-03-261-2/+6
| | | | | | | | | | | | The behavior of the 'min' procedure which converts its parameters to inexact numbers when at least one of them is inexact was causing '%find-best-next' to always return real numbers. * src/mcron/job-specifier.scm (%find-best-next): Preserve the exactness of numbers in NEXT-LIST. * tests/job-specifier.scm ("%find-best-next: exact"): New test. Reported-by: Ludovic Courtès <ludo@gnu.org>
* utils: It's 2018!Mathieu Lirzin2018-03-251-1/+1
| | | | * src/mcron/utils.scm (show-version): Update copyright.
* environment: Refactor configuration environment handlingMathieu Lirzin2018-03-241-35/+38
| | | | | | | | * src/mcron/environment.scm (current-environment-mods): Rename to ... (%current-environment-mods): ... this. Box it using SRFI-111 to be explicit about the mutability of this object. (get-current-environment-mods-copy, clear-environment-mods) (append-environment-mods): New '#:ENVIRON' argument.
* 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 Lirzin2018-03-243-8/+17
| | | | | | * 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.
* job-specifier: Use 'simple-format'Mathieu Lirzin2018-03-231-4/+3
| | | | | * src/mcron/job-specifier.scm (job): Use 'simple-format' instead of 'with-output-to-string'.
* utils: Use 'scandir' instead of custom 'for-each-file'Mathieu Lirzin2018-03-203-23/+11
| | | | | | | | | | | | * 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>
* tests: Add 'schedule.sh'Mathieu Lirzin2018-03-161-1/+4
| | | | | | | * tests/schedule.sh: New test. * Makefile.am (TESTS): Add it. * src/mcron/job-specifier.scm (configuration-time): Use SOURCE_DATE_EPOCH for reproducible tests.
* base: Add 'display-schedule' procedureMathieu Lirzin2018-03-164-30/+27
| | | | | | | | | | | | | 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.
* crontab: Extract procedures from 'main'Mathieu Lirzin2018-03-161-35/+34
| | | | | * src/mcron/scripts/crontab.scm (in-access-file?) (hit-server): New procedures.
* mcron: Handle command line arguments in C with argpMathieu Lirzin2017-09-281-60/+27
| | | | | | | | | | | 'argp' is a convenient and maintainable way to parse command line arguments. Guile doesn't offer an equivalent of this, so the command line handling has been moved to C. * src/mcron.c (parse_args, parse_opt): New functions. (inner_main): Call 'parse_args'. * src/mcron/scripts/mcron.scm (show-help, %options): Delete. (main): Remove command line handling.
* build: Remove "--enable-debug" configure optionMathieu Lirzin2017-09-281-1/+8
| | | | | | | | | | | Unlike C code where debugging impose the "-g" compilation flags. This debugging option only affects Guile code, so using an environment variable works better since it doesn't impose to recompile Mcron or to edit "config.scm". * configure.ac: Remove "--enable-debug" configure option. * src/mcron/config.scm.in (config-debug): Use MCRON_DEBUG environment variable to trigger the debug mode at runtime.
* Add (mcron core) module.Mathieu Lirzin2017-09-281-0/+32
| | | | | This module is an alias for (mcron base) module. This modules is added to keep backward compatibility with Mcron 1.x.
* 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.
* job-specifier: Remove dependency on SRFI-26.Mathieu Lirzin2017-09-281-3/+6
| | | | | * src/mcron/job-specifier.scm (range): Use plain lambda instead of 'cut' and 'cute'.
* 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.
* vixie-specification: Do not use 'and-let*'.Mathieu Lirzin2016-12-281-6/+3
| | | | | * src/mcron/vixie-specification.scm (parse-vixie-environment): Use 'and=>' instead of 'and-let*'

* base: Rewrite 'run-job-loop'.Mathieu Lirzin2016-12-281-44/+33
| | | | | * src/mcron/base.scm (run-job-loop): Use #:optional keyword argument, and 'match'.
* job-specifier: Use #:optional keyword argument.Mathieu Lirzin2016-12-281-26/+28
| | | | | | | | * src/mcron/job-specifier.scm (next-year, next-year-from, next-month) (next-month-from, next-day, next-day-from, next-hour, next-hour-from) (next-minute, next-minute-from, next-second, next-second-from): Use #:optional keyword argument. (maybe-args): Remove unneeded procedure.

| | | | | | * src/mcron/job-specifier.scm (%find-best-next): Call 'inf' thunk instead of defining an arbitrary high integer. (bump-time): Adapt to it.
* all: Separate programs in different executables.Mathieu Lirzin2016-12-015-529/+556
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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'.

* base: Rename (mcron core) module to (mcron base).Mathieu Lirzin2016-05-074-7/+8
| | | | | | | | | | | | | | | | | 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'.
