Concurrency

[Roger Hamilton <ro...@gmail.com>]

I have heard that svn+ssh has a concurreny issue that can brek the
database when committing files. I am in the process of setting up a
Subversion server for a team of up to 20 people to use, is it wise to
set it up this way or would it be more reliable to use SSL?

It was on a blog somewhere - I have lost the link to it now. I have
not seen anyone else comment on this issue so it should be okay, I
just wanted to make sure it was not a huge problem if it is a problem
at all.

Even BDB shouldn't have any concurrency issues as long as you're using
the correct umask settings so that the permissions on repository files
aren't screwed up.

As far as I'm aware, concurrent access can be tricky when the  
repository is BDB-based, but shouldn't be when it's FSFS-based. I'm  
not aware that this is dependent on the protocol. I can't find the  
reference to this right now. Where did you hear that svn+ssh has  
concurrency issues?
