svnadmin: E200002: Serialized hash missing terminator

Answer 1

It means one of the repository files is corrupt!

It could be a revision files in db/revs or it could be a revprop file in db/revprops.

A serialized hash is a series of K/V pairs followed by END:

Take a look at this solution (Python script):

• Runs the 'svnadmin verify -r ' and checks 'serialized hash missing terminator error'.
• If the error is reported, the script reads the revision properties of revision just before that (i.e. revno-1) and add One minute to the time stamp of this revision.The log message is changed 'recovered from corruption' message.
• Now original corrupted revision property file is copied to a backup location and corrected revision property is written in its place.
• The process repeats till get it 'valid revision'. At this point it stops.
