How long does the clang code analysis buldbot
You mean the "beat the living hell out of Wireshark to look for bugs in many different ways" buildbot? :-)
What does it actually *do*?
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,
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
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.
