This is another story about the conversion of a Subversion repository into multiple git repositories. But the question is not about how to do that in general but instead, how to keep the history of the resulting git repository intact, when the files have been moved in Subversion.

The situation looks like this:

Repo/
  trunk/
     ProjectA
     ProjectB
     ....

Whereas the subfolders in trunk were created at some point in time – before the layout was like the following:

Repo/
  ProjectA
  ProjectB
  ....

Now I would like to:

1. Convert the repository to git (git svn clone does this nicely).
2. Extract all subfolders in trunk to separate repositories.

So I went ahead, did the git svn clone {http...} AllProjects and then cloned AllProjects to ProjectA and used git filter-repo --subdirectory-filter trunk/ProjectA within ProjectA.

Now, the following problem appears:

• Within AllProjects I can follow the log for a file from trunk/ProjectA/... and I can see that the file was moved (a real move, not delete and add).
• Within the Repository ProjectA that was created from AllProjects the history only contains all entries of commits that already went to the trunk subfolder.

So even though the files in ProjectA come from AllProjects where all the history is present, all the history of those files in ProjectA is lost for all entries that affected those files before the move to the trunk subfolder.

What am I doing wrong here? This behavior does not make sense to me, why does git cut the history? Is there a way to achieve my goal?
