'svnadmin verify' does not detect incomplete changed-paths sections in FSFS revision files. An incomplete changed-paths list causes issues with commands such as 'svn log -v' and 'svnsync'. 'svn log -v' fails to show all changed paths, and 'svnsync' silently omits the missing paths from a mirror repository.
This problem was described in the mailing list thread for issue
We need to find a way to make 'svnadmin verify' detect this kind of corruption.
One suggestion was to make the FSFS verification code cross-check the changed-paths list of rN with a delta of the directory reps in rN-1 and rN. Any node revision ID change in the directory reps should have a corresponding changed-paths list entry.
