Andrew is really the right person to answer this, but he's really busy
at the moment. The -dev list probably is a slightly better place to ask
this.
I think the memory leaks have been fixed in the current Hg tip. Have
you tried it?
Right, testing against the latest development code (which will be
released with hopefully minimal changes soon) is the best idea.
Otherwise you're likely to be reporting things that are already fixed
- which isn't an effective use of anyone's time :-)
To enable valgrind, make sure you pass the following configure options:
--enable-libc-malloc
(turns off our internal allocator so valgrind can do its job)
--with-valgrind-suppress=/path/to/exceptions.supp
(a file with a list of false positives)
--with-valgrind-log=--log-socket=yourhost:1234
(the location and port where valgrind-listener is running)
After that, just add "crm valgrind" to ha.cf (instead of "crm yes") to
enable it.
This method has the advantage of being easy to enable/disbale without
needing to recompile.
