Subject Re: Can't read length line in file X [500, #200002]
Date Wed, 09 Jul 2014 14:26:04 GMT

I looked at the log of revision comments and found that the broken revision
is purely adding files that are from another repository at a particular
revision number. I'm in the process of get a copy of that repository.

I took a dump of the repository with the corrupt revision up to that broken
revision. When I tried to take an incremental dump from after that revision
to head, a few revisions got dumped, but I then received the "Can't read
length line in file" error for the broken revision. I'm trying to fix the
repository using the solution described in the archives here
<>, where I'd reproduce
the broken revision. I there a way to get a copy of the all the revisions
after the broken one to apply to a new repository?

Thank you
