* Using new Guile command-line-processor.Dale Mellor2020-06-083-175/+67
* 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. Dale Mellor2020-04-205-91/+157
* mcron: Look for local files in local directory....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. Dale Mellor2020-04-201-2/+5
* utils: It's 2020!...* src/mcron/utils.scm (show-version): Update copyright year. Ludovic Courtès2020-02-271-1/+1
* 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 Courtès2020-02-271-22/+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 Courtès2020-02-271-14/+26
* build: Add '--with-sendmail' configure option...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. 宋文武2018-10-071-4/+4
* vixie-time: Refactor 'parse-vixie-time'...* src/mcron/vixie-time.scm (parse-vixie-time): Use 'match' to avoid complex 'car' and 'cdr' usage. Mathieu Lirzin2018-04-081-68/+63
* vixie-time: Refactor 'interpolate-weekdays'...* src/mcron/vixie-time.scm (interpolate-weekdays): Avoid mutation and add 'range-wday' inner procedure. Mathieu Lirzin2018-04-081-18/+11
* vixie-time: Adapt to '%find-best-next' possible infinite result...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. Mathieu Lirzin2018-04-011-10/+13
* utils: Remove 'parse-args'...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. Mathieu Lirzin2018-03-273-13/+5
* job-specifier: Box 'configuration-user' global variable...* 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. Mathieu Lirzin2018-03-271-6/+4
* job-specifier: Fix typo "implement" => "implementation"...* src/mcron/job-specifier.scm (%find-best-next): Fix typo. Mathieu Lirzin2018-03-271-1/+2
* job-specifier: Adapt 'bump-time' to 'next-...-from' procedures...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> Mathieu Lirzin2018-03-261-15/+9
* job-specifier: Preserve '%find-best-next' arguments exactness...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> Mathieu Lirzin2018-03-261-2/+6
* utils: It's 2018!...* src/mcron/utils.scm (show-version): Update copyright. Mathieu Lirzin2018-03-251-1/+1
* environment: Refactor configuration environment handling...* 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. Mathieu Lirzin2018-03-241-35/+38
* 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. Mathieu Lirzin2018-03-241-6/+15
* base: Rewrite 'child-cleanup'...* src/mcron/base.scm (child-cleanup): Use recursion instead of 'do'. Mathieu Lirzin2018-03-241-6/+6
* utils: Add 'get-user'...* src/mcron/utils.scm (get-user): New procedure. * src/mcron/job-specifier.scm (job): Use it. * src/mcron/base.scm (remove-user-jobs): Likewise. Mathieu Lirzin2018-03-243-8/+17
* base: Rewrite 'find-next-jobs' docstring....* src/mcron/base.scm (find-next-jobs): Don't explain the detail of implementation in the docstring. Mathieu Lirzin2018-03-241-15/+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 ... (%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. Mathieu Lirzin2018-03-241-66/+77
* job-specifier: Use 'simple-format'...* src/mcron/job-specifier.scm (job): Use 'simple-format' instead of 'with-output-to-string'. Mathieu Lirzin2018-03-231-4/+3
* utils: Use 'scandir' instead of custom 'for-each-file'...* 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> Mathieu Lirzin2018-03-203-23/+11
* tests: Add 'schedule.sh'...* tests/schedule.sh: New test. * Makefile.am (TESTS): Add it. * src/mcron/job-specifier.scm (configuration-time): Use SOURCE_DATE_EPOCH for reproducible tests. Mathieu Lirzin2018-03-161-1/+4
* 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'. * src/mcron/scripts/mcron.scm (main): Likewise. * doc/mcron.texi (The base module): Document it. Mathieu Lirzin2018-03-164-30/+27
* crontab: Extract procedures from 'main'...* src/mcron/scripts/crontab.scm (in-access-file?) (hit-server): New procedures. Mathieu Lirzin2018-03-161-35/+34
* mcron: Handle command line arguments in C with argp...'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. Mathieu Lirzin2017-09-281-60/+27
* build: Remove "--enable-debug" configure option...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. Mathieu Lirzin2017-09-281-1/+8
