Thanks for noting that this is related to the github implementation.


When Subversion recovers from an so called ‘incomplete’ update, it sends other information
to the server, but the github Subversion compatibility code doesn’t properly implement this
recovery code path. (Their server also has problems handling sparse working copies… something
that is not possible in plain git)


There is not much we can do here in Subversion, as this is technically a protocol violation.
But if github needs more information for fixing this please let them contact me.

Hello devs.

Got Tsvn exception while updating repository frim github (

Actually it happens if initial checkout from repo was canceled by user(for some reason) and
then(after cleanup command) user initiated update command. If checkout perforemed to the end,
next update commands work(well, not found case yet).
