Corey Farrell	79677ead28	refdebug: Create refstats.py script. This allows us to process AO2 statistics for total objects, memory usage, memory overhead and lock usage. * Install refstats.py and reflocks.py into the Asterisk scripts folder. * Enable support for reflocks.py without DEBUG_THREADS. Steal a bit from the ao2 magic to flag when an object lock is used. Remove 'lockobj' from reflocks.py since we can now record 'used' or 'unused' for those objects. Add comments to explain thread safety of the 'struct __priv_data' bitfields. Change-Id: I84e9d679cc86d772cc97c888d9d856a17e0d3a4a	7 years ago
Corey Farrell	13df745278	astobj2: Record lock usage to refs log when DEBUG_THREADS is enabled. When DEBUG_THREADS is enabled we can know if the astobj2 mutex / rwlock was ever used, so it can be recorded in the REF_DEBUG destructor entry. Create contrib/scripts/reflocks.py to process locking used by allocator. This can be used to identify places where AO2_ALLOC_OPT_LOCK_NOLOCK should be used to reduce memory usage.

usage, memory overhead and lock usage.

* Install refstats.py and reflocks.py into the Asterisk scripts folder.
* Enable support for reflocks.py without DEBUG_THREADS.

Remove 'lockobj' from reflocks.py since we can now record 'used' or
'unused' for those objects.

Add comments to explain thread safety of the 'struct __priv_data'
bitfields.

astobj2: Record lock usage to refs log when DEBUG_THREADS is enabled.

When DEBUG_THREADS is enabled we can know if the astobj2 mutex / rwlock
was ever used, so it can be recorded in the REF_DEBUG destructor entry.

Create contrib/scripts/reflocks.py to process locking used by
allocator.  This can be used to identify places where
AO2_ALLOC_OPT_LOCK_NOLOCK should be used to reduce memory usage.
