As always, http://buildbot.kegel.com is just now starting to look stable (kind of like fusion power is always nearly practical). So I'm starting to look at adding valgrind to the buildbot. I won't check for memory leaks at all, since those are too numerous to count. And I'll only valgrind the tests immediately related to each proposed patch.
First, though, I need a complete suppressions file for all existing wine valgrind warnings. That's going to take a while to put together, since some of the warnings don't show up on every run.
And before I bother to automate anything, I'm taking a little detour, looking at the existing warnings, and trying to see if we can make a little progress on some of them.
The script http://code.google.com/p/winezeug/source/browse/trunk/buildbot/runval.sh is how I'm starting to do a manual sweep for valgrind errors. I'm going DLL by DLL, starting with advapi32, looking carefully at each valgrind error.
For each error that looks spurious or expected, I will add a suppression to the existing global suppressions file, http://code.google.com/p/winezeug/source/browse/trunk/valgrind/valgrind-supp...
For each error that looks real, I'll try to understand it and fix it if the error is not deep, or file a wine bug and add a matching suppression to http://code.google.com/p/winezeug/source/browse/trunk/buildbot/valgrind-blac... When bugs get fixed, I'll remove the matching suppressions from that file.
This morning I looked at a grand total of one valgrind warning (in advapi32/security.c), and filed http://bugs.winehq.org/show_bug.cgi?id=28628 for it.
I did glance at a couple more; advapi32/crypt.c has a bunch of expected errors (which I'll probably add to valgrind-suppressions), and atl/atl_ax has a bunch of what look like real errors (which I'll probably file a bug for and add to valgrind-blacklist).
It'll probably take quite a while to catalog the baseline errors and get a complete blacklist. If it takes too long (more than a few weeks), I'll chuck it and do a dumb blanket suppression of all existing warnings.
