Bugzilla Bug 9945

When running rdiff-backup to save data created under MS Windows, there's an
error due to the name of the files:

Exception 'AF_UNIX path too long' raised of class 'socket.error':

This has been discussed on the rdisff-backup mailing list:
http://mail.freesoftware.fsf.org/pipermail/rdiff-backup-users/2002-October/000013.html

And they're proposing this patch:

Could you include it in the ebuild, so everyone could use it.

Thanks in advance for your work.

when you say 'proposing a patch' you mean 'theyre adding this patch' right ?

It says: "Try the attached patch." on the mailing list... I think they're going
to fix this problem, at least I hope, and in the meanwhile, one has to apply the
patch.

Hi, I've added the patch and a fixed ebuild to the CVS. Please allow for some
time for your mirror to carry those and try them out. Please report any problems
here. The new ebuild will is rdiff-backup-0.10.1-r1.ebuild
