but I did not get as far as I would like. Interested parties can find
some very rough patches in the git repository at:
git://repo.or.cz/git/jrn.git tp/svn-fe-wip
The top two patches are completely bogus. No doubt some of the
earlier ones are, too, which is why I do not think they are ready for
review yet, except by extra curious people.
Now the features that would be most useful from fast-import become a
bit clearer. Since a single svn revision can make multiple changes to
a file, the ability to read back the currently staged content for the
current revision would be helpful, like this:
commit refs/remotes/origin/root
mark :100
committer localuser <localuser@xxxxxxxxxxxxxxxxxxx>
data <<END_MESSAGE
from refs/remotes/origin/root^0
M 100644 :72:"trunk/README" "branches/topic/README"
cat "branches/topic/README"
M 100755 inline branches/topic/README
data <<END_FILE
... output from delta application goes here ...
END_FILE
... etc ...
In other words, it would be nice to be able to
1. use ':<mark>:<path>' references to retrieve data from a
previous revision
2. use 'cat <path>' references to retrieve data from the
current revision.
By using these two features, I think we could eliminate the repo_tree
module completely.
David's and Ram's discussions and patches from the last two weeks (or
at least the part I have understood) have been very helpful.
