Message : Parallel automake execution: AUTOMAKE_JOBS. * lib/Automake/Config.in (perl_threads): New global. * automake.in: Use it. If the perl supports interpreter-based threading, then use `threads' and `Thread::Queue'. (handle_makefile, handle_makefiles_serial): New functions, factored out from main. (get_number_of_threads): New function, compute number of threads to use, based on environment variable `AUTOMAKE_JOBS' and number of independent makefiles. (handle_makefiles_threaded): New function. Spawn threads, use thread queue to distribute handling the different makefiles. Collect $exit_code values from threads. (main): Use new functions. * aclocal.in: No threads here. * configure.ac: Substitute PERL_THREADS; enabled with perl >= 5.7.2 and when ithreads are available. * bootstrap (dosubst): Likewise. * Makefile.am (do_subst): Likewise. * lib/Automake/Makefile.am (do_subst): Likewise. * lib/Automake/ChannelDefs.pm: Use `Automake::Config' and `threads'. (verb): Prepend thread ID (tid) to verbose messages. * lib/Automake/Channels.pm (msg): Before exiting, flush stderr, needed for worker threads. * lib/Automake/tests/Makefile.am (TESTS_ENVIRONMENT): Also include the build tree path, so Config.pm is found. * tests/parallel-am.test: New test. * tests/Makefile.am: Update. * doc/automake.texi (Invoking Automake): Document AUTOMAKE_JOBS. * NEWS, THANKS: Update. Report about long execution times by Joakim Tjernlund and others. Signed-off-by: Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
