migrating to git: keep subversion revision numbers (as tags?)

migrating to git: keep subversion revision numbers (as tags?)

[fkater]

Hi,

I would like to completely migrate from subversion to git
(and NOT have subversion enabled anymore). However, I need
to be able to lookup the old subversion revision numbers
later from the git repository. The default seems to be
though, that they are replaced by git sha-1 keys.

It would be completely o.k. here to use git tags for all
those subversion revision numbers (if possible), so, to
create a tag for each subversion revision. However, I have
neither seen any option in git nor found a script which does
that upon cloning (converting) a subversion repo into a git
repo.

Is there a way to do so?

Thank You
 Felix

As I understand it, git-svn stores the SVN revision number in the git
commit message and git-svn log allows queries based on the SVN
revision number. I think you will find having one tag for each SVN
revision number is an abuse of the git tag facility - it makes it much
harder to use for its intended function in git.

There's not really any need to tag every revision with the SVN
revision number.  If you use svn-all-fast-export, or git-svn to do the
SVN -> Git conversion, then the SVN revision numbers will end up as
part of the commit message when it is in Git.

Another way would be to have SVN version numbers in commit
message (--grep option works fine, if those version numbers have 
fixed format). 

The version numbers git-svn outputs are ugly, but filter-branch
can be pretty easily rewrite those into more pretty form,
something like

"This was SVN r123" or "SVN-version: r123".

(adjust to taste)
