tests: move all test-cases into component subdirectories
There are around 300 regression tests, 250 being in tests/bugs. Running partial set of tests/bugs is not easy because this is a flat directory with almost all tests inside. It would be valuable to make partial test/bugs easier, and allow the use of mulitple build hosts for a single commit, each running a subset of the tests for a quicker result. Additional changes made: - correct the include path for *.rc shell libraries and *.py utils - make the testcases pass checkpatch - arequal-checksum in afr/self-heal.t was never executed, now it is - include.rc now complains loudly if it fails to find env.rc Change-Id: I26ffd067e9853d3be1fd63b2f37d8aa0fd1b4fea BUG: 1178685 Reported-by: Emmanuel Dreyfus <> Reported-by: Atin Mukherjee <> URL: Signed-off-by: Niels de Vos <> Reviewed-on: Reviewed-by: Kaleb KEITHLEY <> Reviewed-by: Emmanuel Dreyfus <> Tested-by: Gluster Build System <> Reviewed-by: Vijay Bellur <>

+# Bug 963678 - Test discard functionality
+# Test that basic discard (hole punch) functionality works via the fallocate
+# command line tool. Hole punch deallocates a region of a file, creating a hole
+# and a zero-filled data region. We verify that hole punch works, frees blocks
+# and that subsequent reads do not read stale data (caches are invalidated).
+# NOTE: fuse fallocate is known to be broken with regard to cache invalidation
+# up to 3.9.0 kernels. Therefore, FOPEN_KEEP_CACHE is not used in this
+# test (opens will invalidate the fuse cache).
