[tor-dev] lcov test coverage reports

Hi all,

Would there be interest in using lcov [0] for test coverage analysis?

Obviously, as lcov is an external pacakge, the existing scripts that
only use built in gcov commands must remain.

However, if I were to create a script that generates a pretty, HTML
coverage report using lcov & genhtml, would this be something others
would use? And how would you like to see this implemented? As a custom
make target (e.g., make htmlcoverage + autotools black magic to silently
disable/hide the target if we can't find lcov), or as a standalone
script (i.e., ./scripts/test/run_lcov.sh).

For what it's worth, I've manually run lcov on tor after enabling
coverage through ./configure, and the output seems sane, so I think
from a technical standpoint this would work.

Cheers,
