These scripts are great to see, to me easy coverage reporting is
critical to getting test coverage in practice.
For the bulk of dbus's lifetime I used to have a working "make
coverage-report" that would in one step run the build, run make check,
and then dump out reports much like these you have here (total and file
percentages, and then line-by-line annotated source).
Do you think we could put these into the dbus tree instead of my old C
version that fell behind gcov, and get "make coverage-report" working
again? Having it in perl is fine, it's not a required dependency of
anything and about everyone with gcc/gcov is going to have perl too.
One thing I had in the old tool was that it didn't include lines of code
(and basic blocks) inside #ifdef DBUS_BUILD_TESTS in the statistics,
without that fix you can't get to 100% coverage due to code like:
die("test failed"); // test suite does not cover this line!
