Hi Eric e.a.,
I have a weird git-svn corner case that might interest you (or not at
all). I'd appreciate any help or hints for moving beyond this problem.
I'm using git-svn to do a full commit history analysis of the Zope +
Plone CMS code bases as part of a research project with the University
of Nottingham into open source knowledge dynamics.
One of the repositories I'm importing breaks with a "Checksum mismatch",
indicating a corruption. However, this error message occurs exactly at
the point where the repository was renamed: from "Products.CMFPlone" to
"Plone" (22715->22716). (Yes, it's the Plone core itself that resists
analysis :-()
The git-svn url for the later commits would be:
http://svn-mirror.plone.org/svn/plone/Plone/trunk
Whereas an older part of the code base lives at:
http://svn-mirror.plone.org/svn/plone/Products.CMFPlone/trunk
Funny thing is, git-svn detects this rename upfront but then breaks
anyway. Which raises the questions:
- is this breakage caused by the rename?
- or does git-svn handle the rename, and there is an actual corruption?
- is there any way I can work around this and get a valid or semi-valid
git history for this project?
I don't mind missing a few commits, since I'm not doing code development
on this repository, only statistical analysis.
Solving this would also be helpful for anyone who wants to work on Plone
development through git rather than through raw svn.
