glusterfs.git/tests/bugs/changelog/bug-1321955.t, branch v3.8.4 features/changelog: Don't modify 'pargfid' in 'resolve_pargfid_to_path' 2016-03-31T04:23:19+00:00 Kotresh HR khiremat@redhat.com 2016-03-29T13:36:46+00:00 9746ee75865162af1827337f22a553ea0c3ba2ed If 'changelog' is enabled and 'changelog.capture-del-path' option is on it calls 'resolve_pargfid_to_path' which modifies 'pargfid' sent by caller. 'changelog_unlink' calls this routine directly with 'loc->pargfid' resulting it being modified and point to root instead of actual pargfid. This is a nasty bug and could cause the deletion of entry on root directory instead on actual parent when 'loc->path' is not present. Hence this fix to make 'pargfid' a const pointer and 'resolve_pargfid' to work on copy of pargfid. Glusterfind session creation enables these options by default to capture deleted entry path in changelog. Thanks Pranith for root causing this.

If 'changelog' is enabled and 'changelog.capture-del-path' option is on
it calls 'resolve_pargfid_to_path' which modifies 'pargfid' sent by
caller.  'changelog_unlink' calls this routine directly with
'loc->pargfid' resulting it being modified and point to root instead of
actual pargfid. This is a nasty bug and could cause the deletion of

Glusterfind session creation enables these options by default to
capture deleted entry path in changelog.

Thanks Pranith for root causing this.
