[PATCH 0/4] Coverage support revisited

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Jens asked me at git-merge if coverage support was still available.
Turns out it is, but there were some weirdnesses.  So this should fix
them.  It is reaaaally slow as you still have to run the tests one by
one; despite claims in the wild that it is multiprocess- safe but
thread-unsafe, I am in fact observing the opposite behavior pretty
clearly.  (As before, it switches to sequential tests automatically,
so you have to edit the Makefile if you want to try with parallel
tests.)

Below is the coverage-untested-functions output; it seems submodule.c
is covered, so there is nothing for Jens to do ;-)


Thomas Rast (4):
  coverage: split build target into compile and test
  coverage: do not delete .gcno files before building
  coverage: set DEFAULT_TEST_TARGET to avoid using prove
  coverage: build coverage-untested-functions by default
