将大型SVN存储库迁移到git

Question

I have a large SVN repo (around 140GB) that holds many projects and does not follow the svn recommended directory structure. From all this data (it includes binaries, release builds and dependencies), all I really care about is at an specific path, that actually has a very small history compared to everything else.

All docs I've read so far on SVN-to-Git migration require me to pull the whole SVN repo to Git but this is taking forever, timeouting, going OOM and crashing. Is there any way I can pull only the history for this very specific folder?

Or is there a way I can export the SVN history for this folder alone into a new SVN repo and start the git migration from there?

Answer 1

通过--no-minimize-url，EG，：

git svn clone <SVN_URL>/your/specific/folder --no-minimize-url --no-metadata folder

Answer 2

If you have access to the Subversion repository (not just a working copy), I recommend using svn2git because it will be much faster.

Your rules file will resemble

create repository specific-folder.git
end repository

# note: trailing slash is important
match /trunk/foo/bar/baz/specific-folder/
  repository specific-folder.git
  branch master
end match

# ignore everything else
match /
end match

Then your command will be

svn-all-fast-export --identity-map=my-users --rules=specific-folder.rules \
  --stats --add-metadata /full/path/to/subversion/repo

Note that your new git repository will contain the contents of specific-folder .
