Message-ID: URL: https://gitlist.dev/e/p06240804c41942f6276e%40%5B192.168.1.114%5D ``` 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. ``` ## Björn Steinbrink, 2008-04-02 15:17 Subject: Re: Can I switch a git-svn clone from a file => http 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. > 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 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).

Done >Use filter-branch to change all git-svn-id lines in the log entries. 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? >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). > >HTH >Björn >-- >To unsubscribe from this list: send the line "unsubscribe git" in >the body of a message to majordomo@vger.kernel.org >More majordomo info at http://vger.kernel.org/majordomo-info.html ``` ## Teemu Likonen, 2008-04-03 06:05 Subject: Re: Can I switch a git-svn clone from a file => http url?

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://... ``` ## Stephen Bannasch, 2008-04-04 00:49 Subject: Re: Can I switch a git-svn clone from a file => http url?

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: > >Use filter-branch to change all git-svn-id lines in the log entries. But it wasn't clear to me how to change the git-svn-id lines. ``` ## Björn Steinbrink, 2008-04-05 00:23 Subject: Re: Can I switch a git-svn clone from a file => http url?

Should have been something like: git filter-branch --msg-filter 'sed "s,file:///....,http:///,"' -- --all Björn ```
