Subject: libproc-processtable-perl: Proc::ProcessTable does not know states t, X, x, K for Linux

Hi This bug has been forwarded from http://bugs.debian.org/646785 Proc::ProcessTable does not known about all the states found in Linux source under fs/proc/array.c [1]. [1] http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=464763cf1c6df632dccc8f2f4c7e50163154a2c0 When Proc::ProcessTable encounters such a process, it returns ppt_warn("Ran into unknown state (hex char: %x)", (int) prs->state_c); i.e. for tracing stop processes, unknown state (hex char: 74). There is a bugreport already for the 'X (dead)' case [2]. [2] https://rt.cpan.org/Public/Bug/Display.html?id=54488 Could you add support for these states? Thanks in advance, Salvatore Bonaccorso, Debian Perl Group

Hi, thanks for the report. I plan to rewrite the entire handling by using code from my latest libstatgrab port (runs all Systems I have access to). You can pre-test by downloading it from http://www.netbsd.org/~rehsack/smart-snmpd/ and check the output from examples/process_snapshot Best regards, Jens

Thanks for this info. The link lead me to a 404. But I found the files with http://wwww.netbsd.org/~sno/smart-snmpd/ It sounds good! Today I tried too to work out a patch on current codebase on this, I have attached it. Regards, Salvatore

attached. Apply in Proc-ProcessTable-0.45 directory with patch -np1 < 646785-and-handle-Hex29.patch This adds to previously posted 646785 patch. At least on some systems, commands can contain "(" and ")". See comments in the code.

The command to issue the patch should have been listed as patch -p1 < 646785-and-handle-Hex29.patch (not "-np1").

Hey Salvatore, This has been fixed in the github repo code. https://github.com/jwbargsten/perl-proc-processtable Added mappings (t,K,x,X) for the possible states given in the debain kernel code that were missing in Proc::ProcessTable for Linux. linux-3.2.35/fs/proc/array.c static const char * const task_state_array[] = { "R (running)", /* 0 */ "S (sleeping)", /* 1 */ "D (disk sleep)", /* 2 */ "T (stopped)", /* 4 */ "t (tracing stop)", /* 8 */ "Z (zombie)", /* 16 */ "X (dead)", /* 32 */ "x (dead)", /* 64 */ "K (wakekill)", /* 128 */ "W (waking)", /* 256 */ }; Thanks, Dave On Thu Oct 27 07:26:59 2011, CARNIL wrote: Show quoted text
