Hi, Im not quite sure what im seeing here, but ... the prove test './tests/basic/posixonly.t' should test, well, posix ;). and yet the gcov report says its not being hit: http://lbalbalba.x90x.net/lcov/glusterfs/usr/local/glusterfs/lib/glusterfs/3git/xlator/storage/posix.c.gcov.html Does anyone who has a deeper understanding of both the codebase and the test know if that test should indeed hit that file ? If so, the report is wrong. And if not, the test may need to be changed. Regards, John Smith
