Re: [PATCH] git-svn: use SVN::Ra::get_dir2 when possible

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hmm, I see you are filing the problem against subversion. FWIW,
I am currently using subversion-perl-1.8.10-1.fc20.x86_64 package on fedora 20.
I'll possibly think about filing one under redhat's bugzilla and
let them take it upward too.

 This avoids the following failure

 get_dir2 also has the potential to be more efficient by
 requesting
 less data.

   Jakob's changes causes different access patterns, so
 it's expected the
   sizes vary.  I also changed the cherry pick
 cache and removed the
   _rev_list caching entirely, so it should be much
 smaller now.

   The different merges are fine, I think, as stated in
