I recently made some changes so that buildbot builds report success only
if the number of failed tests is exactly 0. You can see here
buildbot.octave.org:8010
that we currently aren't doing so well.
On the system that runs the following builders
gcc-fedora
gcc-lto-fedora
clang-fedora
some tests fail because of a current fedora bug in osmesa. I suppose I
could (temporarily) disable osmesa on those systems to eliminate the
failures.
On the system that runs the following builders
gcc-6-debian
clang-3.9-debian
8 tests are failing because there is no audio device. I could skip
those tests if there were a way to check whether audio devices are
available, but I'm not sure how to do that. Currently, audiodevinfo
throws an error if there is no audio device. Would it be OK to change
that so it simply returns an empty structure? For my purposes that
would make checking easier, but I'm not sure whether it will cause other
trouble.
The clang-osx build fails because of a problem with integer typedefs
that I reported here:
https://savannah.gnu.org/bugs/?50510
The gcc-6-lto-debian build fails because of a mysterious problem saving
and loading signed 32-bit integers to HDF5 files.
And finally, the mxe-native-on-debian build is failing because the
of-database package configure script is failing with the following message:
checking for PQconnectdb in -lpq... no
configure: error: unable to find the PQconnectdb() function in pq
but I think that's just a missing package problem on my build system, so
I'll fix that and try again.
I'd like to eliminate these failures in some way so that we can expect
to see all builds regularly succeeding. If failures are rare, then I
think we can be more sure that regressions are noticed soon after they
happen.
Comments, suggestions, and help are all welcome.
Thanks,
jwe
