Can I switch a git-svn clone from a file => http url?

I've just created a git-svn clone from a svn repo accessed locally with a file:/// path.

Unfortunately the local svn repo is just a copy of the main svn repo normally accessed with http or https (served through Apache). I was having problems cloning the main svn repository (more details below) so I archived the remote svn repository and copied it to my local hard drive.

Is there an operation I can now do to switch the base url from:

   file:///Path/to/svn/repository/projects

to

   https://svn.concord.org/svn/projects

Here's more details about the problem that got me to this spot:

The svn repo is about 1GB.

I tried several times on a 1000baseT network to git-svn clone the repo. There are about 13000 revisions but the clone process would randomly stop without an error somewhere between revision 400 and 1200.

This was the command I was using:

git svn clone https://svn.concord.org/svn/projects

I'm running git version 1.5.4.4 (installed via ports) on MacOS 10.5.2.

Have you tried to edit the .git/config? The key to look for is svn-remote.svn.url.

I guess you should have used the --rewrite-root option when you did the clone. Then the metadata in the log entries would already point to the right URL and you could just adjust the URL in .git/config and drop the rewriteRoot entry there.

Basically, this should work:

Change the URL to the repo in your .git/config. Use filter-branch to change all git-svn-id lines in the log entries. Delete the .rev_map.* files in .git/svn/* Run git svn fetch (rebuilds the .rev_map.* files).

The filter-branch call should use the --msg-filter option to change the log entries and should apply to all the svn branches/tags/trunk (or just use " -- --all", if there's nothing that may not be filtered).

Thanks Björn,

Done

I've just started using git so please forgive the beginner questions.

What should I change the log entries to?

Here's what the log entries look like now:

$ git-filter-branch --msg-filter 'echo $GIT_COMMIT' ^MRewrite 89817efa5b290d375786a5af9a0dcc338df8a68c (1/13099)^MRewrite b090d1d40cba2c66a494d52e370317487d103484 (2/13099)^M

Do you mean each one should just be re-written to a new SHA1 keys? If so how should I generate new SHA1 keys?

Ouch, that replaced your commit messages with the sha1 hashes... Should have been something like: git filter-branch --msg-filter 'sed "s,file:///....,http:///,"' -- --all

I know two options:

1. Keep your current Git repo but set the url and rewriteroot options 
in .git/config:

[svn-remote "svn"]
	url = http://...
	rewriteroot = file:///...

Your commit messages will still have git-svn-id pointing at file:///... url but it should work fine.

2. Convert your repo again:

$ mkdir repo ; cd repo $ git svn init --rewrite-root=http://... file:///... $ git svn fetch

This way you'll create new Git repo from file:///... url but commit messages will have git-svn-id's url pointing at http://... . After that set the correct remote url to .git/config:

[svn-remote "svn"]
	url = http://...

Thanks Teemu,

That took a while but worked.

I also removed the rewriteRoot line from config after editing the url.

I think I might have achieved the same effect more quickly with Björn's suggestion to use:

  git-filter-branch --msg-filter

to:

But it wasn't clear to me how to change the git-svn-id lines.
