[ovs-dev] [RFC 0/4] testsuite code coverage usability fixes, lcov

[Lance Richardson]

This series addresses usability issues when executing the testsuite
on builds configured with --enable-coverage and introduces basic
support for generating HTML code coverage reports via lcov.

Currently when running "make check" on a build with coverage enabled,
nearly all test cases will fail due to unexpected messages on stderr
of the form:
    profiling:...*.gcda: Merge mismatch for function *

This happens because daemons created for each test case are killed
at the end of the test case, and if a daemon happens to be killed
while in the middle of writing coverage information to a gcda file,
the gcda file will be corrupted.

These errors can be avoided by ensuring that deamons have fully
exited when given the "exit" command before executing any cleanup
actions.

Lance Richardson (4):
  tests: Make OVS_APP_EXIT_AND_WAIT() wait for process termination
  tests: make as() function as documented
  tests: consistently use OVS_APP_EXIT_AND_WAIT() for daemon termination
  tests: enable basic lcov code coverage reporting support
