Today, when I was merging my master branch it seemed that I had circa 830 commits to mutual parent with gerrit/github and the same situation occur for gerrit/gihub (it has circa 830 comitis to our mutual parent), so I start digging and found out that uncommon commits (this 830) look (as far as commit comment) the same.

So my suspicion is that someone (legoktm) has been independently importing new commits from svn to git repo (so they look exactly the same but don't have the same commit hash) and has pushed them to directly gerrit without merging with master?

Could we do something to avoid that kind of situations?

cheers
