I’m really quite frustrated at this point. I have an existing hg repository that has months of coding history in it, and I want to get this into a private Github repository so I can work on it from there. Unfortunately I use Windows and I can’t seem to find any way to convert the repository that I can actually get to work properly. Practically every bit of help and advice I can find online seems to assume I’m running from some kind *nix shell, which I’m not.
I currently have installed: TortoiseHG, Python 3.1 and Git for Windows.
What I’ve tried:
hg-init plugin for hg – When I try to use the gexport command (and others from hg-git), I just get strings of python exceptions. I totally can’t get git to even recognise the gremote command. I tried following what was here: http://github.com/blog/439-hg-git-mercurial-plugin
hg-to-git (fast-export) – All tutorials keep expecting me to run a .sh file. Another stackoverflow thread seemed to imply that Powershell can run .sh files, but I can’t make it run them for the life of me. Example: http://hivelogic.com/articles/converting-from-mercurial-to-git
Mercurial to git converter – http://permalink.gmane.org/gmane.comp.version-control.git/36601 – This one doesn’t want to work when I run it via Python, which complains that it has a syntax error on line 44. I don’t know python, so I’ve got no idea.
Four hours of Google searching and wading through useless tutorials and people-more-fortunate-than-me singing the praises of each supposedly-helpful blog post, but I haven’t gotten anywhere with this. Can anyone offer any assistance or suggestions for me to try?
Or tell me what the url is for this hg repo of yours, and I can convert it for you.
There is a lot of conflicting information about how to convert Mercurial repositories to Git on Windows. It really is pretty easy and only requires TortoiseHg and Git to be installed.
Enable hg-git by adding the following to your Mercurial config file (%Userprofile%mercurial.ini):
[extensions] hggit = hgext.bookmarks = [git] intree = True
Navigate to the repository directory (that contains the .hg subdirectory) on the command line and execute the following commands:
hg bookmark -r default master hg gexport --debug git config --bool core.bare false git reset HEAD -- .
You can find a detailed description of these steps in my blog article on the subject.
Have you considered installing msysgit? The git bash shell it gives you should be able to run .sh files.
Everything I’ve read about these Hg converters for Git does point out one obvious error you’ve made: Using Python 3!
Those Python errors you’ve been getting are due to scripts like hg-git and fast-export being built using Python 2.6. Python 3 treats “print” differently, hence your errors.
Either rewrite the scripts to work with your version or install Python 2.6.
Make sure to add it to your PATH setting. Same goes for when you install msysGit. Be sure you choose the second option at install to add Git to your path.
You also need Mercurial For Python, available at TortoiseHG’s thg-winbuild project:
The file will be named ‘mercurial-2.2.2.win-amd64-py2.6.exe’ for 64-bit Windows
and ‘mercurial-2.2.2.win32-py2.6.exe’ for 32-bit. While you’re at it, get the companion Mercurial 2.2.2 installer, just in case.
Although you stated you don’t wish to install yet another VCS software, using any of these Hg converters requires Mercurial to also be installed.
Another pitfall to look out for is these converters may not work with the latest versions of Mercurial. You might need to experiment a bit with older releases to find one that works well with the scripts.
Be sure to carefully read through the tutorials and the Readme files for whichever converter you settle upon using. It seems a lot of your grief and trouble stems from having impatiently jumped into the deep end after only skimming the documentation.
There are patches available that add Mercurial support to Git and msysGit, but you’ll need to be comfortable with patching and compiling from source if you wish to follow that route.
It might seem silly (or a solution for the desperate…) but I think that Bazaar has good support for both Hg and Git repositories, and it works well on Windows.
So if all else fails, maybe you can use bzr-hg and bzr-git to make the conversion…
If the original Mercurial repo is available on the web, and if you don’t mind using GitHub to do this, converting from Mercurial to Git is now trivially easy:
- Log in to GitHub.
- Click the
+in the upper-right.
- Supply the Mercurial repository’s URL, a name for it under your account, and whether it’ll be public or private.
Begin importand wait.
You don’t even need to stay on the page after that. After a while, GitHub will notify you by e-mail that the import is finished.
