Hi,
I got aware of several projects who hosted a Git repository on Savannah being affected by their filesystem corruption. The good Savannah people put back some revisions from their backup, which are something like a month old.
Some people seem to think that it has adverse effects to fetch those obsolete branch revisions with a "git fetch".
This mail tries to serve to cool everybody down: nobody can take away from you what you already fetched: in the default set up, you will still have the "reflogs", i.e. "git log -g origin/master" will show you a "forced update" to the obsolete revision, but as the next commit, you will have the most up-to-date revision you fetched before.
And, oh, your local branches are unaffected.
You can even help the project maintainers if you have a newer revision than is the current revision on Savannah...
Ciao, Dscho
P.S.: congratulations to everybody who switched to a distributed version control system before this corruption...
