<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">While hunting for a channel ref leak, I found that after running the refcounter utility, there were a whole host of ao2 object ref leaks. Wondering if that was just my test causing that, I started Asterisk and immediately stopped it.
Nope, lots of ref leaks still.
This patch cleans up a fair number of them - so that at least with my admittedly limited configuration (which had a number of modules excluded), there were no longer any ao2 ref leaks on Asterisk shutdown. Most of these are simply Asterisk not properly cleaning up after itself on shutdown; however, a few could arguably result in slow growing memory leaks, particularly in systems that used frequent reloads.
Still haven't found the channel ref leak, but this does remove a lot of error messages.
Note that while this patch is for trunk, a version should be applied to 1.8, 10, and 11 as well.
For Richard:
I noticed that some of the internally allocated nodes in astobj2 would not be represented in a REF_DEBUG log, as they never used a 'debug' version of ao2_alloc or ao2_ref. Unfortunately, a few code paths resulted in those same nodes showing up in the REF_DEBUG log, leading to warnings that nodes were appearing that were never allocated. This patch manages to get all of the nodes represented in a REF_DEBUG log; however, I imagine that for the red/black tree work, this is going to be compounded. If you have another approach you'd like to take other than what I have here, let me know.</pre>
