Proc-ProcessTable

Revision history for Perl extension Proc::ProcessTable.

0.01 Mon Jun 8 11:37:47 1998

original version; created by h2xs 1.18

0.03 Sun Jul 26 09:07:50 1998

added argument to va_end to make linux-ppc work

0.04 Fri Aug 14 22:51:31 1998

preliminary pre-alpha solaris support

0.05 Wed Dec 9 18:47:39 1998

fixed minor compilation problems for solaris. Changed rss to bytes on linux for consistency with solaris; also added "time" and "ctime" fields to linux for consistency. Updated documentation in Process.pm. Folded in AIX port by David Paquet <david-paquet@usa.net>.

0.06 Wed Dec 9 23:42:05 1998

added HPUX port by Mike Romberg <romberg@fsl.noaa.gov>.

0.07 Wed Jan 6 14:57:04 1999

added FreeBSD port by Slaven Rezic <eserte@cs.tu-berlin.de>.

0.08 Thu Feb 4 00:35:53 1999

Fixed bug in solaris hints file that was looking for a version of solaris returned by "uname -r" as > 2.5, when "uname -r" returns the "SunOS" version of 5.5. Fixed bug in linux module in which only the first field of the command line was getting passed in cmndline attribute.

0.09 Fri Feb 19 23:23:53 1999

Fixed bug in Linux.c, fopen() called without corresponding fclose. Added empty DESTROY subs to ProcessTable.pm and Process.pm to fix occasional problems with mod_perl. Changed all instances of sv_undef in ProcessTable.xs to PL_sv_undef to comply with new standard.

0.10 Sat Feb 20 11:29:35 1999

Added code to ProcessTable.xs to check perl patchlevel version and use either PL_sv_undef or sv_undef since lots of people are still using older versions of perl.

0.11 Sat Mar 6 19:04:39 1999

Fixed code that checked perl patchlevel version to check directly for definition of PL_sv_undef and define it as sv_undef if it's not there, since it's not clear what patchlevel we need to check for. Also fixed embarrassing and unnecessary call to close() a string in Solaris.c

0.12 Sun Mar 21 10:53:56 1999

Hopefully the final fix for the sv_undef buglet.

0.14 Fri May 14 06:30:15 1999

Added port for IRIX from W. Phillip Moore <wpm@ms.com> in 0.13, but forgot to add files to MANIFEST and edit Changes (Duh). W. Phillip Moore's port also included a minor patch for Solaris to get the page size from the system.

0.15 Tue Jun 1 21:33:16 1999

Added patch from Peter ? <hooft@natlab.research.philips.com> for IRIX version differences. There seems to be a lot of IRIX out there.

0.16 Mon Aug 9 22:59:46 1999

Added nanosecond Solaris patch from Rolf Petter Halle <rph@nextel.no>. Added port for dec_osf from Bernhard Schmalhofer <Bernhard.Schmalhofer@fazi.de>, which included new version of test code as well. Added bsdi port from Sean Eskins <sean@gilasoft.com>.

0.17 Thu Aug 19 10:57:16 1999

Lost connection to ISP during upload to PAUSE, and PAUSE won't let me reload it so I have to increment the version number. Kind of annoying.

0.18 Thu Aug 19 10:57:16 1999

Fixed bug (at least for linux) in Makefile.PL that was causing ProcessTable.xs not to be converted to ProcessTable.c; this was carelessly introduced by me with integration of the port to dec_osf. Added port for netbsd from Peter Reich <pr@alles.prima.de>.

0.19 Mon Aug 30 00:22:02 1999

Reinstated 'OBJECT' argument in WriteMakefile in Makefile.PL since it was breaking the build on dec-osf, but this time with explicit object files to look for which seems to work, at least under Linux. Why this should be necessary is unclear. Added "fname" field to HPUX (was "cmd") for consistency with other ports and for new test. Added very basic "README.hpux". Added check in ProcessTable.pm to prune search tree for unreadable directories when finding TTY list; this was causing spurious errors during build on dec_osf since some directories under /dev are readable only by root.

0.20 Wed Sep 8 22:27:28 1999

Added "fields" method to module to return list of fields supported for the current architecture. This is implemented in a slightly kludgy way, since it needs to call the table method if the table method hasn't been called before, since only the table method knows the names of the fields. Also changed the test code to dump all the fields/values available for the current process table, instead of just dumping pids and "fname" which isn't supported on all architectures (though it should be). Added "example.pl" file which contains the same code.

0.21 Fri Sep 10 12:32:13 1999

Bug fix; new "fields" method was crapping out on everything except Linux-Intel.

0.22 Tue Oct 5 07:47:54 1999

Bug fix for Solaris; nanosecond process times are only available on 2.6 (and above?); this was causing the module to dump core on earlier systems. Also, size and rss appear to be in kilobytes, not pages in 2.6 and above (they are in pages in the struct prpsinfo in < 2.6, but also available directly as bytes).

0.23 Mon Nov 1 08:32:54 1999

Added patch from Dave Alden <alden@math.ohio-state.edu> for solaris "nice" and "onproc" fields.

0.24 Thu Jan 20 08:00:30 2000

Added patches from Noel Paul <NoelP@mincom.com> for dec_osf pctcpu and pctmem, and for IRIX for pctmem.

0.25 Thu Feb 3 11:20:27 2000

Added patch from F. Buirey <f.buirey@saprr.fr> for AIX SMP.

0.26 Fri Feb 11 16:43:48 2000

Added Proc::Killall from Aaraon Sherman <ajs@ajs.com>.

0.27 Thu Jun 29 08:27:23 2000

Added patch for converting jiffies to microseconds in linux from Philip Gwyn <fil@pied.nu>. Added patch from Slaven Rezic <eserte@cs.tu-berlin.de> for FreeBSD and to make Storable optional.

0.28 Mon Aug 14 16:31:43 MYT 2000

Patch from Slaven Rezic <eserte@cs.tu-berlin.de> to make test script -w clean.

0.29 Tue Jan 9 07:36:13 EST 2001

Patch from Wolfgang Friebel <Wolfgang.Friebel@desy.de> for os/HPUX.c to make the time method return useful values. Patch from Adrian Phillips <tandem@dnmi.no> to fix AIX cmndline field. Patch from Tryggvi Farestveit <tryggvi@firmanet.is> to fix bug in cmndline under Linux. Killfam.pm module from Steve Lidie <sol0@Lehigh.EDU>.

0.30 Sun Mar 4 05:05:26 EST 2001

Patch from David Good <dgood@stratasource.com> for 32-bit HPUX 11.0 support via the 64-bit interface. Port to Unixware 7.x from Martin Lucina <mato@catalyst.net.nz>. Upgraded status to beta :)

0.31 Fri Jun 1 08:27:03 EDT 2001

Removed bogus test code line from os/Linux.c that was opening "/tmp/tedddi".

0.32 Sun Aug 19 04:45:25 EDT 2001

        -SunOS port from Shawn Clifford <shawn.a.clifford@lmco.com>. 
        Patch from Thomas Linden <tom@daemon.de> for additional Linux
        fields. Patch for bsdi from Nicolas Belan <belan@matranet.com>
        to add cmndline.

0.33 Wed Oct 10 15:50:17 EDT 2001

        -Fixed Solaris large file environment problem (by turning off
        large file environment CCFLAGS!). Patches from Chris Adams
        <cmadams@hiwaay.net> for TTYs with device number(s) zero and
        Digital Unix table() call to read processes. Added
        README.taint for workarounds for perl -T. Changed umask for
        644 permissions for /tmp/TTYDEVS.

0.34 Sun Feb 24 21:55:07 EST 2002

        -Corrected documentation type pointed out by Marcus Crafter
        <crafterm@osa.de>. Fix for JIFFIES_TO_MICROSECONDS potential 
        int overflow on linux from Stephen Pillinger
        <S.M.Pillinger@cs.bham.ac.uk>. Patch for File::Find routine 
        on AIX (broken POSIX?) from H.Merijn Brand
        <h.m.brand@hccnet.nl>. Big linux code cleanup patch from
        Anthony Higa <anthony@squareusa.com>; I think this also
        fixes the linux-ppc problem reported by Marcus Crafter.

0.35 Mon Jul 1 11:24:43 EDT 2002

        -Patch from Thomas Glanzmann <sithglan@stud.uni-erlangen.de>
        to fix starttime overflow bug on linux. This should also fix
        multiprocessor starttime bugs. He says there is another
        overflow after 25 days of uptime though :(
        Nearly identical patches from Doug Lewis
        <dlewis@exchange.webmd.net> and Jan L. Peterson
        <jlp@flipdog.com> to fix taint problem. Patch from Peter van
        Hooft <hooft@natlab.research.philips.com> to allow non-root
        users to list processes on IRIX.

0.36 Tue Nov 5 23:04:12 EST 2002

        -Patch for documentation typo for Killfam.pm from Mike Castle
        <dalgoda@ix.netcom.com>. Patch for AIX v4.2 from James
        FitzGibbon <james@ehlo.com> to take advantage of newer OS API;
        this also required addition of a new return type (long-long,
        specified as "j") to ProcessTable.xs. Patch to add new field
        "numthr" for number of threads for Solaris from Joseph
        Cavanaugh <Joseph.Cavanaugh@FMR.COM>. Patch for linux compiler
        warnings from Marcus Crafter <crafterm@osa.de>. Changed HPUX
        "cmd" field to "cmndline" for consistency with other ports at
        the suggestion of Craig Cook <cncook@gene.COM>. Windows port
        via Cygwin from J Robert Ray <jrray@jrray.org>. Patch for
        multithread support under Solaris from Kong Li
        <Kong.Li@netiq.com>. Patch for File::Find::prune tty mapping
        buglet from <jon@jjb.demon.co.uk>. Changed behavior of
        store_ttydev() in ProcessTable.xs to insert an empty string
        for processes that don't have a tty, instead of having it
        return undef. I think this will fix a problem reported on
        HPUX by H.Merijn Brand <h.m.brand@hccnet.nl>. Changed ttynums
        to be treated as unsigned to fix occasional negative ttynum
        bug reported by Daniel Berger <djberge@qwest.com>.

0.37 Fri Nov 8 09:50:56 EST 2002

        -Patch from Philip Molter <philip@texas.net> to fix typo in
        Solaris.c.

0.38 Fri Dec 6 22:23:20 EST 2002

        -Fixed my omission of new AIX files from MANIFEST. Patch from
        Tim Cutts <tjrc@sanger.ac.uk> for Tru64 clusters.

0.39 Fri Oct 3 11:45:21 MDT 2003

        -Project is now hosted on SourceForge. Patch from Aaron
        Sherman <ajs@ajs.com> from rt.cpan.org ticket #2578 to add a
        warn function ppt_warn() instead of sending errors to stderr;
        changed linux, bsdi and aix. Added ppt_croak and updated
        PORTING docs. Added port to Darwin from Tom Wyant
        <twyant3@comcast.net>. Added port to Nonstop-UX from Mike
        Steinert <mike.steinert@motorola.com>. Patch from
        James.FitzGibbon <James.FitzGibbon@target.com> for AIX 5.1
        command line args. Added note to README.dec_osf that root
        access is required.

0.40 Sun Jul 10 19:10:16 MDT 2005

        -Added patch for support of FreeBSD-5 via kvm from Oleg King
        <king2@kaluga.ru>. Added contrib directory and pswait script
        from dominix <dominix@despammed.com>. Patch from Steve Linn
        <steve@rhythm.com> to handle processes larger than 2GB. Added
        jiffies-to-microseconds patch for linux from Jason A. Smith
        <jason@jazbo.dyndns.org>. Added patch from rt.cpan.org ticket
        #12951 to fix Solaris 8 with multi-threaded Perl where 
        readdir_r is defined differently for POSIX compiles. Patch for
        misreport of PID in cygwin (rt.cpan.org ticket #12840).
        Fix for FC4 gcc-4 buffer overrun complaint.

0.41 Fri Jun 30 22:04:43 MDT 2006

        -Port to openbsd from <bsd@openbsd.rutgers.edu>. Fix for
        EOVERFLOW in HPUX 11.11 from <alan.martin@oracle.com>
        (rt.cpan.org ticket #18932). Module now requires perl 5.6 as
        suggested by <rdusong@tique.org> (rt.cpan.org ticket
        #15279). Patches from <reini.urban@gmail.com> for killall to
        use fname if cmndline is not defined and rename PID_ZOMBIE to
        PID_ORPHANED under cygwin (rt.cpan.org ticket #14837,
        #14836). Fixed empty pctmem bug on linux due to change in
        format of /proc/meminfo (hopefully this format is stable
        now??).

0.42 Fri Jan 25 22:29:00 MST 2008

        -Patch to fix PROC_FS define in Solaris 5.10 from jlv
        <jloverso@mathworks.com>; patch to replace kinfo array and use
        KINFO structure on darwin. Patch from Steve Linn
        <steve@rhythm.com> for x86_64 linux. Shortened test code so it
        only shows info for current process.

0.43 Thu Jul 17 20:59:23 MDT 2008

        -Changed 'my $TTYDEVSFILE;' to 'our' to permit multiple
        versions of perl (rt.cpan.org bug ID 37722); fixed up include
        file order in os/Linux.h so module will build on OpenSuse 11
        per request of Steve Linn <steve@rhythm.com>; fixed warning
        under perl 5,10 (rt.cpan.org bug ID 36666); fixes for numerous
        problems on darwin from  Tom Wyant <twyant3@comcast.net>
        (rt.cpan.org bug IDs 24331, 32761, and 33698); fix for ARG_MAX
        dynamic configuration in os/Linux.h (rt.cpan.org bug ID 36283).

        -Patch from Tom Wyant <twyant3@comcast.net> for darwin issues
        that didn't make it into 0.43.

0.45 Mon Sep 8 09:13:14 MDT 2008

        -Patch from Milosz Tanski <mtanski@gridapp.com> to make module
        thread-safe on linux (rt.cpan.org ID 38709). Patch from Scott
        Davis <darkpreludesi@hotmail.com> for new constructor flag
        enable_ttys, which when set to 0 disables traversing the
        device tree.
