<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">It would be a bit cleaner to use the glob module to get a list of matching paths and then get the length of the list.</pre>

This bit of code was added to prevent re-copying (or in case of valgrind's xml files reparsing) the ast# directories from previous tests. I think it's better although ugly to leave this bit of code to match __archive_ast_logs(), although I am now reducing it to just:
while os.path.isdir("%s/ast%d" % (ast_directories, self.existing_ast_instances+1)):
self.existing_ast_instances += 1

<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;">This patch adds support for running Asterisk under Valgrind (say: Val-Grinned) to check for all sorts of nasty runtime bugs. This started off with a post to asterisk-dev list by nitesh.bansal@gmail.com, and he wrote and contributed the initial version. So if you find this useful, be sure to thank him. Then I made extensive changes and additions, so if the code stinks, blame me.
The following has been done:
- Check runtests.py arguments for --valgrind and --valgrind-gensupp flags, pass via environ to TestCase.py
- Note previously existing instances of ast# logs to insure we only process new log/xml files
- Increase reactor timeout by x5 when valgrind enabled
- Patch to reactor_stop() to insure it does even when exceptions occur in deferred stack
- Add valgrind with correct arguments into executable path
- After run, check valgrind.xml for errors, parse and condense them into something more managable
- If -gensup mode enabled, write suppressions to logs/(test)/ast#/valgrind.supp that can be added (manually)
- A default valgrind.supp "suppressions" file is in configs/ to prevent complaints about known unfixables
Notes:
- valgrind can be triggered by argument to runtests.py, export VALGRIND=true, or in test-config.yaml
- configs/valgrind.supp will be used if found, but tests/(test)/configs/valgrind.supp will take precedence
- valgrind-gensupp mode will create example suppressions file, during which no suppressions occur
