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.
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.
* 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.
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'.
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.
* 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.
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'.
* 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.
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.
This allows using 'mcron' before it is installed without hardcoding the
local build environment in the executable.
* build-aux/pre-inst-env.in: New script.
* configure.ac (AC_CONFIG_FILES): Create it.
(AC_CONFIG_HEADER): Add 'config.h'.
(moduledir): New variable.
(PACKAGE_LOAD_PATH): new C preprocessor macro.
* mcron.c: Include "config.h".
(main): Don't overwrite Guile load paths.
(inner_main): Prepend Mcron modules load paths.
* Makefile.am (.scm.go, doc/mcron.1): Use 'pre-inst-env'.
(mcron_CFLAGS): Remove GUILE_LOAD_PATH macro.
(noinst_SCRIPTS): New variable.
* .gitignore: Update.
* configure.ac (AM_SILENT_RULES): Use macro.
* makefile.am (doc/mcron.1): Use $(AM_V_HELP2MAN).
(AM_V_HELP2MAN, AM_V_HELP2MAN_, AM_V_HELP2MAN_): New variables.
* scm/mcron/makefile.am (.scm.go): Use $(AM_V_GUILEC).
(AM_V_GUILEC, AM_V_GUILEC_, AM_V_GUILEC_): New variables.
Remove 'ed' hack to eval content of scm/mcron/main.scm in the C wrapper.
Use proper libguile functions instead.
* scm/mcron/main.scm (mcron main): New module.
(show-version, show-package-information, show-help, main): Remove
extra newline characters in strings.
* mcron.c.template: Rename to ...
* mcron.c: ... this.
(inner_main): Set current module to (mcron main).
* makefile.ed: Delete file.
* configure.ac: Remove check for 'ed'.
* makefile.am: Adjust accordingly.
* .gitignore: Likewise.
