Revision history for Perl extension PCP::PMDA.
1.15 Thu Sep 5 11:22:34 EST 2013
- Fix a subtle reference counting problem in the hash
indom code.
- Consistently use unsigned type to index the indom
table.
1.14 Tue Jul 10 11:40:14 EST 2012
- Add support for hash-based indom handling via PMDA
cache interfaces in libpcp_pmda. This introduces a
routine for looking up opaque PMDA data from instid
(pmda_inst_lookup) suitable for fetch callback use.
- Fix pmda_inst_name interface used by dtsrun PMDA -
using an incorrect value for indom lookup. This is
now consistent with the other instance interfaces,
and dtsrun PMDA (not widely used) has been fixed.
- Fix instance interface arguments - no current PMDA
makes use of this, but if one did (pmdaoracle will)
it would be given the internal indom identifier and
not the handle given to all other indom interfaces.
- Remove unused parameters to internal preinstance()
and prefetch() routines, no visible effect for any
PMDAs but the wrapper code becomes more readable.
- Fix help file handling which (for current gcc/perl
combinations at least) was using potentially-freed
memory.
1.13 Thu Oct 20 11:50:18 EST 2011
- Add an interface to allow a PMDA to drop privileges.
- Fix pmda_long and pmda_ulong 32-bit detection.
1.12 Fri Jul 22 11:15:41 EST 2011
- Ensure local fetch and instance wrapper routines
are always called. Otherwise refresh interface
doesn't work, and pmns_refresh may not be called
in all situations where it should be.
1.11 Wed May 11 21:04:09 EST 2011
- Make file tail non-blocking so it can be used for
named pipes as well as regular files.
1.10 Thu Nov 25 03:30:18 EST 2010
- Convert to using dynamic namespace interfaces.
- Added metric and indom table clearing interfaces.
1.09 Sun Aug 1 09:04:38 EST 2010
- Fix memory leak in fetch routine string handling.
1.08 Thu Nov 19 10:37:26 EST 2009
- Fix typo on name export for pmda_inst_name.
- Add a fast path lookup in pmda_inst_name for direct
instance identifier to offset case (common).
- When tailing logfiles, seek to end initially so we
don't spend potentially copious amounts of time on
scanning the entire log file - we only want events
that happen after PMDA startup to be counted too.
1.07 Fri Aug 21 09:27:51 EST 2009
- Add helper routines to determine native long sizes.
1.06 Wed Jul 22 12:49:43 EST 2009
- Ensure the process runs in its own process group,
and block SIGTERM in atexit handler. This resolves
a regression in the 1.05 fix for reaping children.
1.05 Tue Jul 8 16:19:49 EST 2009
- Explicitly free all local temporaries immediately
for routines that call Perl from C (fixes memleak).
- Fix an off-by-one when handling long input lines.
- Terminate any children started by the PMDA at exit.
1.04 Mon Jul 6 11:08:20 EST 2009
- Rewrote PMNS file generation to use libpcp routines.
1.03 Wed Jun 10 14:53:05 EST 2009
- Incorporated Win32 build changes (paths, etc).
- Remove (unneeded) use of hsearch and <search.h>.
1.02 Tue Jun 2 17:16:25 EST 2009
- Implemented log file rotation and host reconnect handling.
- Generally improved the file "tail" mode of operation.
1.01 Fri Feb 13 17:33:31 EST 2009
- Added simple instance name lookup routine.
1.00 Thu Aug 20 08:48:14 EST 2008
- Added several API components, 1st stable version.
0.04 Mon Feb 25 15:01:33 EST 2008
- Smaller, but still incompatible, API refinements.
0.03 Sun Feb 24 09:06:39 EST 2008
- API changes, moved existing Perl PMDAs out into PCP.
0.02 Wed Feb 20 16:38:38 EST 2008
- port forward to Perl API changes (circa Perl 5.6).
0.01 Mon Sep 20 09:01:16 EST 1999
- original version; created by h2xs 1.18
