* Merge system-wide Vixie cron updates.Dale Mellor2023-03-181-1/+9
|\ | | | | | | | | | | | | | | | | | | | | | | | | I don't believe that anyone should be running system-wide cron processes these days (the attack surface is rather large), but should use separate per-user or per-service mcron daemon processes. But mcron is advertised as a drop-in Vixie replacement, so we should do what we can to make it safe in this use case. I've performed a basic vetting of the changes against vandalism, but haven't verified the correctness of the code or done any checking; the changes are being accepted on the basis that almost anything is an improvement on what currently exists.
| * crontab-access: replace with wrapper, rename to crontab-access-real.ulfvonbelow2023-03-181-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The wrapper has two purposes: 1. Not being a script, thereby eliminating the issues with setuid scripts. 2. Purging the environment. crontab-access-real has no need for any environment variables to do its work, so to prevent tampering with dynamic linker, libc, or guile, we may as well just unset them all. This wrapper does introduce a requirement for a C compiler. Ideally it would be conditional based on whether the wrapper is even going to be built, but autoconf doesn't like that one bit. Someone with more experience with autotools should sort that out. In the meantime I guess anyone wanting to build without a C compiler being present is going to have to edit configure.ac and re-run bootstrap. * src/crontab-access.in: renamed to src/crontab-access-real.in * src/crontab-access.c.in: new file, wrapper for crontab-access-real. * Makefile.am: inform about crontab-access.c.in and name change to crontab-access-real. Put crontab-access-real in libexecdir.

* Lose hope of running against guile 2.2 or earlier.Dale Mellor2022-07-071-1/+1
| | | | | | | | | | We have previously allowed versions 2.0 and 2.2 to get past the configure stage, but all versions of guile before 3.0 have in fact failed to compile the code due to syntax errors for some time now. * build-aux/guix.scm: package depends on guile@3 * configure.ac: only look for guile version 3 * src/mcron/base.scm: drop allowance for old-fashioned (version 2.0) select

| | | | * configure.ac: Remove unecessary PKG_CHECK_MODULES invocation.
* build: Detect guile M4 macro expansion errorsMathieu Lirzin2020-05-171-1/+8
| | | | | | | | This ensures that the absence of 'pkg-config' or 'guile' M4 macros expansion do not pass the bootstrap step. * configure.ac: Allow or forbid some M4 macros patterns in the generated 'configure' script.

* project: banish need for C compilerDale Mellor2020-04-201-31/+24
| | | | | | | | | | 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.

* build: Add '--with-sendmail' configure option宋文武2018-10-071-20/+10
| | | | | | | | | | | | 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.
* build: Add "maint.mk"Mathieu Lirzin2018-03-261-0/+6
| | | | | | * maint.mk: New maintainer-only Makefile fragment. * Makefile.am: Include it. * configure.ac: Substitute "maint.mk" content when it exists.
* build: Check non-standard C functions at configure timeMathieu Lirzin2018-03-231-0/+6
| | | | * configure.ac: Check 'argp_parse' and 'asprintf' presence.
* maint: Update copyright yearsMathieu Lirzin2018-03-201-1/+1
|
* build: Support 'make installcheck'Mathieu Lirzin2018-03-201-1/+1
| | | | | | | * configure.ac: Pass 'std-options' to AM_INIT_AUTOMAKE to check that the "--help" and "--version" options can be passed to installed programs. * Makefile.am (installcheck-local): New rule which checks the programs presence and configuration.
* build: Handle all programs names transformationsMathieu Lirzin2018-03-201-8/+0
| | | | | | | | | | | | Previously only prepending a prefix was handled when installing 'crontab'. Using the 'transform' Make macro allows the installation process to support generic transformations as defined by the '--program-suffix' and '--program-transform-name' configure options. * configure.ac: Don't substitue '@real_program_prefix@'. * Makefile.am (fpp): Remove. (transform_exe): New macro. [MULTI_USER] (install-exec-hook): Use it when installing 'crontab'.
* build: Reverse '--disable-multi-user' effectMathieu Lirzin2018-03-191-1/+1
| | | | | | | | This fixes a bug where the '--disable-multi-user' was actually having the reverse effect of installing 'cron' and 'crontab'. * configure.ac: Reverse equality test when setting 'MULTI_USER' Automake conditional.
* maint: Remove obsolete configure checksMathieu Lirzin2018-03-191-18/+0
| | | | | | * configure.ac: Don't check for 'sed' and 'cp' programs which are considered portable. Don't check for 'head' and 'which' programs which are not required.
* Replace generic C wrapper with individual programsMathieu Lirzin2017-09-281-1/+1
| | | | | | | | | | | * src/wrapper.c: Delete. * src/crontab.c: New file. * src/mcron.c: Likewise. * src/cron.c: Likewise. * configure.ac: Adapt 'AC_CONFIG_DIR' to use "src/mcron.c". * Makefile.am (bin_crontab_SOURCES, bin_cron_SOURCES) (bin_mcron_SOURCES): Use new files. (bin_cron_CPPFLAGS, bin_mcron_CPPFLAGS, bin_crontab_CPPFLAGS): Delete.
* wrapper: Move 'wrap_env_path' to a new 'utils' module.Mathieu Lirzin2017-09-281-0/+2
| | | | | | | | | * src/wrapper.c: Move 'wrap_env_path' to ... * src/utils.h: ... here. New module. * src/utils.c: New file. * configure.ac: Use AC_PROG_RANLIB and AM_PROG_AR. * Makefile.am (noinst_LIBRARIES, src_libmcron_a_SOURCES): New variables. (LDADD): Add 'src/libmcron.a'.
* build: Remove "--enable-debug" configure optionMathieu Lirzin2017-09-281-14/+0
| | | | | | | | | | | 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.
* build: Remove "maintainer-mode" configure option.Mathieu Lirzin2017-09-281-4/+0
| | | | * configure.ac: Remove "maintainer-mode" configure option.
* build: Replace "--enable-no-vixie-clobber" with "--disable-multi-user".Mathieu Lirzin2017-09-281-12/+6
| | | | | | | | | | | | | | | | * configure.ac: Define "--disable-multi-user" option instead of "--enable-no-vixie-clobber". * Makefile.am (install-exec-hook) [MULTI_USER]: Only set crontab setuid bit. (bin_PROGRAMS): Keep only 'mcron' by default. (bin_PROGRAMS) [MULTI_USER]: Add 'crontab' (sbin_PROGRAMS) [MULTI_USER]: Add 'cron'. (noinst_PROGRAMS) [!MULTI_USER]: Add 'cron' and 'crontab'. (dist_man_MANS): Move 'crontab.1' and 'cron.8' ... (extra_mans): here. New variable. (dist_man_MANS) [MULTI_USER]: Add it. (all-local) [!MULTI_USER]: New target. Depend on it. (EXTRA_DIST) [!MULTI_USER]: Distribute it. (MAINTAINERCLEANFILES): Clean it.

* build: Support Guile 2.2.Mathieu Lirzin2017-09-281-11/+14
| | | | | | * configure.ac: Use 'GUILE_PKG' and 'GUILE_PROGS'. Remove explicit Guile version check and check for 'guild'. Honor $GUILE_EFFECTIVE_VERSION in 'moduledir'.

* build: Define PACKAGE_LOAD_PATH in Makefile.Mathieu Lirzin2016-12-011-3/+1
| | | | | | | | | | | | Previously PACKAGE_LOAD_PATH was set in config header which wasn't correctly expanded due to the presence of ${prefix} in ${moduledir}. Let 'make' handle the expansion. * Makefile.am (AM_CPPFLAGS): New variable. (cron_CPPFLAGS, crontab_CPPFLAGS, mcron_CPPFLAGS): Use it. * configure.ac (PACKAGE_LOAD_PATH): Undefine it. (AC_CONFIG_HEADER): Remove macro. * src/mcron.c: Adapt to it.
