The partial list in my previous message said: scan-build, running the Clang static analyzer; cov-build, building to prepare to hand Wireshark off to Coverity; fuzz-menagerie, repeatedly running fuzzed capture files through TShark to make sure it doesn't crash. There's also a phase in which it runs capture files with random data ("random" in the sense of "generated by a pseudo-random number generator") through TShark as well.
It looks like some of the crash bugs it submits are GUI-specific
Unlikely, given that it's testing TShark, not Wireshark, with the fuzzed captures. See tools/fuzz-test.sh.
and only occur way down the packet list, so presumably it actually loads the fuzzed files in wireshark
Nope. It really does run them through TShark; where has the buildbot filed a bug in which *Wireshark* crashed?
Does it also try some of the graphs/analyzers?
No, it doesn't test any of the Wireshark GUI.
I ask because I can't repo a crash with bug 9887 by just viewing it,
Perhaps: 1) for some unknown reason, it crashes on Ubuntu (64-bit x86) but not OS X (64-bit x86 in your case, as you are, as I remember, running a recent OS X version); 2) you have different preferences set (I think the buildbot has an empty set of preferences, so the defaults are used); 3) perhaps, for some reason, it crashes in TShark but doesn't crash in Wireshark - for example, if you don't have any color filters set and don't have a display filter, the path where it reads in the capture doesn't generate a protocol tree, but I think the TShark test generates a protocol tree.
but if I select Telephony->Voip Calls... boom goes the dynamite.
That might be a separate bug. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
