debuging_tools: Create the ast_coredumper utility
This utility allows easy manipulation of asterisk coredumps. * Configurable search paths and patterns for existing coredumps * Can generate a consistent coredump from the running instance * Can dump the lock_infos table from a coredump * Dumps backtraces to separate files... - thread apply 1 bt full -> <coredump>.thread1.txt - thread apply all bt -> <coredump>.brief.txt - thread apply all bt full -> <coredump>.full.txt - lock_infos table -> <coredump>.locks.txt * Can tarball corefiles and optionally delete them after processing * Can tarball results files and optionally delete them after processing * Converts ':' in coredump and results file names '-' to facilitate uploading. Jira for instance, won't accept file names with colons in them. Tested on Fedora24+, Ubuntu14+, Debian6+, CentOS6+ and FreeBSD9+[1]. [1] For *BSDs, the "devel/gdb" package might have to be installed to get a recent gdb. The utility will check all instances of gdb it finds in $PATH and if one isn't found that can run python, it prints a friendly error. Change-Id: I935d37ab9db85ef923f32b05579897f0893d33cd

NAME

$prog - Dump and/or format asterisk coredump files
|

|

SYNOPSIS
|
||||
$prog [ --help ] [ --running | --RUNNING ] [ --latest ]
|
||||
[ --tarball-coredumps ] [ --delete-coredumps-after ]
|
||||
[ --tarball-results ] [ --delete-results-after ]
|

[ --no-default-search ] [ --append-coredumps ]

[ <coredump> | <pattern> ... ]
|
||||
|
||||
DESCRIPTION
|
||||
|
||||
Extracts backtraces and lock tables from Asterisk coredump files.
|
||||
For each coredump found, 4 new result files are created:
|
||||
- <coredump>.brief.txt: The output of "thread apply all bt".
|
||||
|
||||
- <coredump>.thread1.txt: The output of "thread apply 1 bt full".
|
||||
|
||||
- <coredump>.full.txt: The output of "thread apply all bt full".
|
||||
|
||||
- <coredump>.locks.txt: If asterisk was compiled with
|
||||
"DEBUG_THREADS", this file will contain a dump of the locks
|
||||
table similar to doing a "core show locks" from the asterisk
|
||||
CLI.
|
||||
|
||||
Optional features:
|
||||
- The running asterisk process can be suspended and dumped.
|
||||
- The coredumps can be merged into a tarball.
|
||||
- The coredumps can be deleted after processing.
|
||||
- The results files can be merged into a tarball.
|
||||
- The results files can be deleted after processing.
|
||||
|
||||
Options:
|
||||
|
||||
--help
|
||||
Print this help.
|
||||
|
||||
--running
|
||||
Create a coredump from the running asterisk instance and
|
||||
process it along with any other coredumps found (if any).
|
||||
WARNING: This WILL interrupt call processing. You will be
|
||||
asked to confirm.
|
||||
|
||||
--RUNNING
|
||||
Same as --running but without the confirmation prompt.
|
||||
DANGEROUS!!
|
||||
|
||||
--latest
|
||||
Process only the latest coredump from those specified (based
|
||||
on last-modified time). If a dump of the running process was
|
||||
requested, it is always included in addition to the latest
|
||||
from the existing coredumps.
|
||||
|
||||
--tarball-coredumps
|
||||
Creates a gzipped tarball of all coredumps processed.
|
||||
The tarball name will be:
|
||||
/tmp/asterisk.<timestamp>.coredumps.tar.gz
|
||||
|
||||
--delete-coredumps-after
|
||||
Deletes all processed coredumps regardless of whether
|
||||
a tarball was created.
|
||||
|
||||
--tarball-results
|
||||
Creates a gzipped tarball of all result files produced.
|
||||
The tarball name will be:
|
||||
/tmp/asterisk.<timestamp>.results.tar.gz
|
||||
|
||||
--delete-results-after
|
||||
Deletes all processed results regardless of whether
|
||||
a tarball was created. It probably doesn't make sense
|
||||
to use this option unless you have also specified
|
||||
--tarball-results.
|
||||
|
||||
--no-default-search
|
||||
Ignore COREDUMPS from the config files and process only
|
||||
coredumps listed on the command line (if any) and/or
|
||||
the running asterisk instance (if requested).
|
||||
|
||||
--append-coredumps
|
||||
Append any coredumps specified on the command line to the
|
||||
config file specified ones instead of overriding them.
|
||||
|
||||
<coredump> | <pattern>
|
||||
A list of coredumps or coredump search patterns. Unless
|
||||
--append-coredumps was specified, these entries will override
|
||||
those specified in the config files.
|
||||
|
||||
Any resulting file that isn't actually a coredump is silently
|
||||
ignored. If your patterns contains spaces be sure to only
|
||||
quote the portion of the pattern that DOESN'T contain wildcard
|
||||
expressions. If you quote the whole pattern, it won't be
|
||||
expanded.
|
||||
|
||||
If --no-default-search is specified and no files are specified
|
||||
on the command line, then the only the running asterisk process
|
||||
will be dumped (if requested). Otherwise if no files are
|
||||
specified on the command line the value of COREDUMPS from
|
||||
ast_debug_tools.conf will be used. Failing that, the following
|
||||
patterns will be used:
|
||||
/tmp/core[-._]asterisk!(*.txt)
|
||||
/tmp/core[-._]\$(hostname)!(*.txt)
|
||||
|
||||
NOTES
|
||||
The script relies on not only bash, but also recent GNU date and
|
||||
gdb with python support. *BSD operating systems may require
|
||||
installation of the 'coreutils' and 'devel/gdb' packagess and minor
|
||||
tweaking of the ast_debug_tools.conf file.
|
||||
|
||||
Any files output will have ':' characters changed to '-'. This is
|
||||
to facilitate uploading those files to Jira which doesn't like the
|
||||
colons.
