It would not surprise me at all if gcov files are *highly* version
dependent. I don't know one way or the other, but it seems very possible.

Looking at how it's run automatically might help:

You should also add 'coverage: true' for the ceph task overrides.
This way daemons are killed with SIGTERM, and the atexit function
that outputs coverage information will run.
Then you don't need your patch changing the flavor either.
For each task X, the docstring for teuthology.task.X.task documents
example usage and extra options like this.
Hi,
That helped a lot, thanks :-) I think I'm almost there. After running:
./virtualenv/bin/teuthology --archive /tmp/a1 /srv/3node_rgw.yaml
wget -O /tmp/build/tmp.tgz
http://gitbuilder.ceph.com/ceph-tarball-precise-x86_64-gcov/sha1/$(cat
/tmp/a1/ceph-sha1)/ceph.x86_64.tgz
echo ceph_build_output_dir: /tmp/build >> ~/.teuthology.yaml
./virtualenv/bin/teuthology-coverage -v --html-output /tmp/html
--lcov-output /tmp/lcov --cov-tools-dir /srv/teuthology/coverage /tmp
I get

I'm using
lcov: LCOV version 1.9
The only problem I can think of is that the machine I'm running lcov
on is a Debian GNU/Linux Wheezy, trying to analyze coverage for
binaries created for Ubuntu Precise. They are both amd64 but .gcno
files may have dependencies to the toolchain.
Did you ever run into similar problems ?
I think I did when I built and ran on debian, and it was fixed with a
later version of lcov (I think 1.9-2). I didn't try doing the coverage
analysis on a different distribution from where ceph was built and run
though, so that may also cause some issues.
