Moving from mercurial to git

For a penguin, it's better to do this:

There is a tool hg-fast-export .

It can be found here:

git clone http://repo.or.cz/r/fast-export.git /tmp/fast-export 

Need to get a mercurial turnip:

 hg clone <remote repo URL> /tmp/hg-repo 

Next you need to create an author matching file.

 cd /tmp/hg-repo hg log | grep user: | sort | uniq | sed 's/user: *//' > ../authors 

In / tmp / authors there will be approximately the following content:

 bob bob@localhost bob <bob@company.com> bob jones <bob <AT> company <DOT> com> Bob Jones <bob@company.com> Joe Smith <joe@company.com> 

In the example above, the same person (Bob) made changes under five different names, only one of which is correct, and one does not at all correspond to the Git format. hg-fast-export allows you to quickly remedy the situation by adding = {new name and email address} to each line we want to change; To leave the name as it is, simply delete the lines. If all the names look good, this file is not required at all. In our example, we want the data to look like this:

 bob=Bob Jones <bob@company.com> bob@localhost=Bob Jones <bob@company.com> bob jones <bob <AT> company <DOT> com>=Bob Jones <bob@company.com> bob <bob@company.com>=Bob Jones <bob@company.com> 

Then you need to create a Git repository and run the export:

 git init /tmp/converted cd /tmp/converted /tmp/fast-export/hg-fast-export.sh -r /tmp/hg-repo -A /tmp/authors 

The -r flag indicates the Mercurial repository to be converted, and the -A flag specifies a file with correspondences between authors. The script goes over the Mercurial change sets and converts them into a fast-import script in Git. And send the change to the turnip gita:

 git remote add origin git@my-git-server:myrepository.git git push origin --all 

For Windows, there are almost only a few other commands:

 cd c:\projects hg clone <remote repo URL> hg-repo git init converted git clone http://repo.or.cz/r/fast-export.git 

Edit c: \ projects \ fast-export \ hg-fast-export.py . The beginning of this script needs to be replaced with this:

 #!/usr/bin/env python # Copyright (c) 2007, 2008 Rocco Rutte <pdmef@gmx.net> and others. # License: MIT <http://www.opensource.org/licenses/mit-license.php> import sys # import mercurial libraries from zip: sys.path.append(r'C:\Program Files (x86)\Mercurial\library.zip') from mercurial import node from hg2git import setup_repo, fixup_user, get_branch, get_changeset from hg2git import load_cache, save_cache, get_git_sha1, set_default_branch, set_origin_name from optparse import OptionParser import re import os 

Copy fast-export to converted ignoring the .git folder. Next: cd converted and create a file here.axtxt by analogy from the linux version.

And hg-fast-export.sh -rc:\projects\hg-repo -A authors.txt Done. Then you can upload git turnips to the server.
