Svnsync against MapGuide repository fails with chunk delimiter was invalid

[trevorwekel]

I am creating a mirror of the MapGuide svn repository using svnsync. I have been able to sucessfully pull up to revision 2793 but I am getting "Chunk delimiter was invalid" errors when I try to svnsync past this point.

Numerous posts on the web seem to indicate that svnsync can fail for various reasons and a suggested workaround is to svnadmin dump.

Can I get a dump of the remaining revisions? It should be less than a gigabyte.

svnadmin dump /path/to/mapguide --revision 2794:3780 > 2794to3780.dump

Hmm... that's weird. Our svnsync mirror has all of the revisions up to r3780 ​http://svnmirror.osgeo.org/mapguide/ I wonder if your problem might have been related to our recent spat of freezups and overloads that we're investigating.

I've seen this kind of error fairly consistently on the OSGeo server when doing standard (not svnsync) checkouts of large repositories, and I'd just written it down to http connection limiting or something similar.

I thought that at some point svn dumps were being made available via a web share for backup purposes?

Yep, they are ​http://svn.osgeo.org/dumps/mapguide/ but they need to be manually cat'ted together.

I've run an svnsync on a local mapguide repository overnight, and had no problems of this sort. If this i s still a current problem, please feel free to reopen this ticket, and I will do my best to investigate further.
