git fast-import: how to prevent incremental commit with no changes
Hi, I'm trying to script a setup that would periodically import a tarball to git with fast-import. But things do not always change, so I'd like fast-import to be able to not do the commit in case there is no change. That is, I'm constructing the commit with deleteall + importing each object by mark after that. Now, in case nothing changed, fast-import will happily create an empty commit for me. Would it be possible to add some flag that would make commit fail in case nothing changed? Any suggestions how to do this? Thanks, Timo -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I am not sure if such a conditional logically belongs to what fast-import does. Would it be an option for your script to rewind the HEAD after the import is done and it finds that the tarball did not have anything interesting new? Yes, this is what I ended up with for now. I wanted to avoid this mostly so that I would not need to run git gc --prune=now or similar after each import (or at least not often).
