ReSync failed after subversion code added with bad encoding in file path.

[tjd_10@…]

A user committed a folder with [] square brackets. This resulted in encoding errors in other clients and the following error in Trac:

SubversionException: ("Filesystem path 'Async-Processes [AKOR]/ViewAsync.asp' is neither a file nor a directory", 160013)

I renamed the directory and this solved the issue for any other applications. Running a resync did not solve the error in Trac.

Did you ever find a way to resolve this?

Trac doesn't do anything special with "[]" and there can't be encoding issues with those characters. The problem was more a Subversion issue, as the SubversionException stated:

Filesystem path 'Async-Processes [AKOR]/ViewAsync.asp' is neither a file nor a directory

When Trac does a resync, it goes through all the existing revisions, so doing a rename after the fact could not help.

Maybe using svndumpfilter to eliminate the buggy change would have worked, but there's nothing we could have done at the Trac level (well, besides introducing a Node.UNKNOWN type ;-) )
