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.
Fetching third-party files inside a make rule is convenient and less
error prone since 'make' has access to '$srcdir'.
* build-aux/gnu-fetch: Delete.
* maint.mk (WGET, git_sv_host, sv_git_am, sv_git_gl)
(fetchfiles): New macros.
(fetch): New target.
* HACKING <Updating auxilary scripts>: Update instructions.
* tests/init.sh: New test framework from Gnulib.
* tests/basic.sh: New test.
* Makefile.am (TESTS): Add it.
(TEST_EXTENSIONS): Add '.sh'.
(SH_LOG_COMPILER): Use 'pre-inst-env'.
(EXTRA_DIST): Add 'tests/init.sh'.
* build-aux/pre-inst-env.in: export $srcdir for shell tests.
* 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.
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.
