You might be aware that the most fundamental difference between Mercurial and Git is that Mercurial branches are a property of the commit (so a commit belongs to a branch), while Git branches are pointers (so a branch points to a commit). Some Git-hosting services like GitHub do not allow files any larger than 50 MB. I experimented with several file sizes and chose 40 MB based on the size of the smallest SQL file it had found. $ java -jar $bfg_cleaner/bfg.jar -strip-blobs-bigger-than 40M $target $ git reflog expire -expire =now -all $ git gc -prune =now -aggressive To do this, I used BFG Repo-Cleaner, a pun on the existing git-filter-branch and the Big Friendly Giant, I suppose.

At several points in the past, some large-ish SQL and ZIP files were unwittingly committed into the repository, which inflated its size quite significantly. I set the repository to be bare at the end of my script just so that I could prevent myself from accidentally committing things to it while I was experimenting.Īfter being absolutely certain I no longer needed to migrate new changes, it was time to strip down the repository.

To update the Git repository with new changes from the Mercurial repository, it suffices to run the hg-fast-export script again, but there has to be absolutely no changes made to the Git repository, or else it would refuse to update. The -force flag was necessary to deal with closed branches, which prompt the error Repository has at least one unnamed head. hg-fast-export.sh -r $source -force -A reformatted-authors.txt Luckily, the aberrant author names mostly followed regular patterns ― and I do mean regular.

The first step was to obtain a table of everyone’s Active Directory username, full name, and emails from IT, then use it to parse the author names currently in the commit logs it into the mandatory username format, and save the mapping 'hgformat'='gitformat' to be used later. On the other hand, Git requires a username and an email. However, this was only a style rule and not enforced by Mercurial itself, which meant that the commits were rife with violations, from jochan, which was what TortoiseHg would automatically fill in for you, to Jonathan Chan to Jonathan Chan to to jochan to blank author names, somehow ― you get the gist. We had enforced username-only author names for the sake of some TeamCity configuration, so in my case my commit author name was jochan. But of course, every specific case has its own specific problems. Luckily, I wasn’t the first one to have to do that, so there were a number of resources I could reference, namely these two.

A few months ago I had to figure out how to migrate a 4 GB repository from Mercurial to Git, and trim the size down along the way.
