build: refactor how lists of coreutils programs are defined This is in preparation of future changes. Still, this patch leaves the build system in a better shape; true, with more indirections, but also with less convoluted and brittle hacks. Unfortunately, this commit also makes some rebuild rules incomplete; that will son be fixed by follow-up patches. * build-aux/gen-lists-of-programs.sh: New, generates autoconf and automake input fragments that define "lists" of all coreutils programs, with further distinctions about how and when these programs should be built (by default; if the system is capable enough; only if the user asks for them explicitly). This is useful to avoid duplicating the definitions of these lists among several files (at least 'configure.ac' 'src/Makefile.am'); such duplication had proved a source of inconsistencies and bugs in the past. And the pre-existing way to avoid such duplication, as implemented in 'configure.ac' before this patch, was overly complex and brittle. * Makefile.am (EXTRA_DIST): Distribute the new script. * bootstrap.conf (bootstrap_post_import_hook): Run the new script to generate 'm4/cu-progs.m4' and 'src/cu-progs.mk'. * .gitignore: Ignore those files. * configure.ac: Include 'm4/cu-progs.m4', and decidedly simplify most of the program lists definition and processing accordingly. * src/Makefile.am: Similarly include 'src/cu-progs.mk', containing definition of variables $(default__progs), $(no_install__progs) and $(build_if_possible__progs). Accordingly ... (no_install__progs, build_if_possible__progs): ... remove. (EXTRA_DIST): Adjust definition. Adjust a comment.

build: man page generation: degrade gracefully when perl is lacking Since commit v8.19-118-g57da212, our 'dist-hook' rule tweaked the distributed Makefile.in to make each man page 'man/foo.1' depend on the corresponding source 'src/foo.c' rather than the corresponding program 'src/foo'. That was done to accommodate systems without perl, which cannot run help2man to regenerate the manpage after its corresponding program has been built. This seems a right and proper graceful degradation, in that the man pages dependencies are still 100% correct in a git checkout, while being more lax but "more portable" in a distribution tarball. Alas, that is not the case in practice, as it turns out the tweaked Makefile makes the building of man pages unreliable and potentially incorrect! In fact, assume that instead of the correct a dependency: man/ls.1: src/ls we have the laxer one: man/ls.1: src/ls.c and think of what happens if a user modifies, say, 'src/ls.c', and then runs "make -j4" to rebuild everything. The make process will see that it has to rebuild the man page 'man/ls.1' (because its prerequisite 'src/ls.c' has changed), but won't see that it has to rebuild 'src/ls' *before* re-running 'help2man' to generate that man page; so, if 'man/ls.1' is rebuilt before 'src/ls' (which can happen with concurrent make), our user will get either a build error (if 'src/ls' did non exist) or, worse, a man page with an up-to-date timestamp but an out-of-date content. And what's even worse in all of this is that this problem will be present also for users who have perl installed: this is not a "graceful degradation" at all! In our situation, the best and simplest way to implement a graceful degradation it to keep the correct dependencies for man pages (that is, "man/ls.1: src/ls"), and if perl is not present, just generate dummy man pages reporting that built-time issue and redirecting the user back to either the info documentation or the '--help' output. As a consequence of this change, we also stop distributing man pages, since they will now be generated unconditionally. * Makefile.am (do-not-require-help2man): Remove. (dist-hook): Don't depend on it. * man/local.mk: Remove an obsolete comment. (EXTRA_DIST): Stop distributing generated man pages. ($(EXTRA_MANS)): This no longer needs to depend on $(all_programs). (MAINTAINERCLEANFILES): $(ALL_MANS) Do not list it here, and ... (CLEANFILES): ... list it here, instead. (.x.1): Instead of warning if perl is missing, but then trying to run 'help2man' unconditionally, simply run ... (run_help2man): ... the command referenced by this new variable, that expands to a proper invocation of 'help2man' if perl is present, and to an invocation of a shell script generating a dummy manpage if it is not. (EXTRA_DIST): Distribute that shell script. * man/dummy-man: New shell script. * NEWS (Build-related): Mention this. Fixes coreutils http://bugs.gnu.org/12715.
