I tried to do an SVN DCommit (git-svn) using TGIT. It
used to work
flawlessly. I didn't change anything in my checkout, but suddenly
it doesn't work anymore and I get an error: ERROR from SVN:
Authorization failed: Cannot negotiate authentication mechanism
I had a look after this issue and it's caused by the ancient SVN
binary that's shipped with msysGit (SVN 1.4.6). Since moving our
server to LDAP user authentication, we require at least SVN 1.5.0 from
June 2008 on the client side. I didn't expect even older binaries to
be still in use, but apparently they are, and the msysGit people
aren't giving this issue high priority (see
https://github.com/msysgit/msysgit/wiki/Subversion-is-too-old)
Anyway, SVN 1.4.6 should still work when accessing our repository over
https:// instead of svn://. To change the URL for your existing Git
repository, please do the following:
* Open the .git/config file of your repository and change the URL from
svn:// to https:// there.
* Do an "SVN Fetch" with TortoiseGit.
This needs to fetch at least one new revision!! If not, commit some
dummy revision first and do the "SVN Fetch" afterwards.
* Do an "SVN Rebase" with TortoiseGit to rebase your commits on top of
the newly fetched revision.
* Finally, do the "SVN DCommit". It should properly connect to the
https:// repository now and do your commits.
The other possible workaround may be checking out the git-svn repo
using the https:// URL from scratch, creating a patch serial from your
existing repository and applying it on the new Git checkout. But I
believe this to take much more time.
