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.
* 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.
* configure.ac: Use 'GUILE_PKG' and 'GUILE_PROGS'. Remove explicit Guile
version check and check for 'guild'. Honor $GUILE_EFFECTIVE_VERSION in
'moduledir'.
* src/wrapper.c (wrap_env_path): New function.
(main): Use it.
(inner_main): Let 'wrap_env_path' set the environment variables.
Don't use 'scm_c_eval_string' when calling 'main' procedure.
* Makefile.am (AM_CPPFLAGS): Define _GNU_SOURCE for 'asprintf'.
* build-aux/git-version-gen: New script.
* configure.ac (AC_INIT): Use it.
(AC_REQUIRE_AUX_FILE): Distribute it.
* Makefile.am (.version): New target.
(BUILT_SOURCES, EXTRA_DIST): Add it.
(dist-hook): Generate ".tarball-version".
* .gitignore: Update.
* src/mcron/job-specifier.scm (current-action-time): Rename to ...
(%current-action-time): ... this. Make it a parameter object.
(job, maybe-args): Adapt.
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.
* configure.ac (AM_INIT_AUTOMAKE): Add more warnings.
* Makefile.am (AM_V_GUILEC, AM_V_GUILEC_, AM_V_GUILEC_0): Rename to ...
(guilec_verbose, guilec_verbose_, guilec_verbose_0): ... these. Make them
more portable. This follows an example from Automake manual.
* Makefile.am (dist_man_MANS): Add 'cron' and 'crontab' man page.
Generate man pages in $(srcdir).
(MAINTAINERCLEANFILES, gen_man): New variables.
(AM_V_HELP2MAN, AM_V_HELP2MAN_, AM_V_HELP2MAN_0): Delete unneeded variables.
($(srcdir)/doc/crontab.1, $(srcdir)/doc/cron.8): New targets.
(doc/mcron.1): Rename to ...
($(srcdir)/doc/mcron.1)): ... this.
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.
