If you use SVN on OSX with an SSL repository you may have run into SSL errors similar to this when doing complex operations like large diffs: SSL negotiation failed: SSL error: parse tlsext
This is caused by a bug in the libneon that is bundled with OS X — libneon is the WebDAV client used to negotiate with SVN.
There are two options to solve this:
- Upgrade the system libneon (bad idea, as OS X can overwrite it in any update)
- Compile SVN/Neon from scratch
- Wait for the binaries to be updated
- Switch to SVN+SSH
Of all of these, these most feasible it to compile SVN/Neon from scratch, but how to do it such that it doesn’t break anything, and co-exists nicely with your system.
Enter: Homebrew
Homebrew is a simple tool for compiling stuff from source without needing complex ebuilds, custom patches, etc. And it co-exists with the current OSX system — utilizing
in every case possible, the system libraries instead of doing everything from scratch like macports.
Install homebrew then do the following:
$ brew edit neon
Then change the neon version to 0.29.3 and remove the md5sum (it’ll bitch on install, but still work).
Then you should be able to just do:
$ brew install svn
Note: I installed 1.6.6, and it’s currently at 1.6.9, if 1.6.6 doesn’t work, follow the instructions above for neon, and switch to any version you like.
Next, you likely have a /usr/bin/svn (symlink? I didn’t check, perhaps it’s the xcode version?) just move that out of the way using:
$ sudo mv /usr/bin/svn /usr/bin/svn.bak
Finally, like me, you probably already have svn installed in /opt/subversion, go ahead and rename this directory, and check /opt/local/bin for another copy.
That should do it :)
