[Queue-developers] new intermediate development Queue version

[QingLong <qin...@Bo...>]

	Hello!

   I've just commited a bunch of patches to queue-development CVS tree
 at sourceforge. Notes on the changes made:

    --- Created a longliving file descriptor (debug_fd) and a stream
        (debug_stream) used for debug output. Having these fd and stream
        opened on debug log eliminates necessity of lifting privileges
        each time one wants to append a record to debug file.
        Also this way of log file writing is considered as more fast.

    --- Changed order and policy of std(in|out|err) redirection from/to
        user terminal, log file, debug log, /dev/null, etc to separate
        messages generated by user command from Queued's own debug
        and error output.

    --- Changed conditions under which some signals (listed in ignore[])
        are ignored (queued.c main()). Now they are ignored only if
        running in backround (irrespective of debug mode).
        This change was made in a try to fix bug recently reported
        by Gert Van den Eynde <gvd...@sc...> (``Alarm clock'' death).

    --- Added _GNU_SOURCE and _XOPEN_SOURCE to config.h
        to enable those extensions when available.

    --- Added check for [gs]et*[ug]id() functions to configure.in.

    --- Performed some code cleaning: added header files inclusions,
        function prototypes, removed unused variables,
        synced printf() formats with argument types, etc.

    --- Added a few library functions return status checking/handling
        to ensure successfull fd dup2()ing, close()ing, etc.

    --- Added a few trace messages (activated by --debug or --verbose).

    --- Fixed typo (of my own) in queued.c readpro():
        the macro is HAVE_GETRLIMIT rather than HAVE_RLIMIT.

    --- Changed debugdir ownership check:
        made it work correctly for non-root installation as well.
        The necessity of this change was pointed out by
        Kai Harrekilde-Petersen <kh...@ex...>.
        I hope I have managed to fix the buglet.

   I have not yet committed changes to derived stuff like configure
 and Makefile.in, so one should probably run
               automake --add-missing
               autoheader
               autoconf
 prior to ./configure. I hope you already have automake et al
 already installed on your systems.

   As the changes made, namely the std(in/out/err) one, touch
 critical parts of code, the new stuff does need steady testing.
 Please give it try and send feedback to the mailing list.
 Thank you.

	QingLong.
