PROGRAM:

NAME

git-remote-hg - bidirectional bridge between Git and Mercurial

SYNOPSIS

git clone hg::<hg repository>

DESCRIPTION

This tool allows you to transparently clone, fetch and push to and from Mercurial
repositories as if they were Git ones.

To use it you simply need to use the "hg::" prefix when specifying a remote URL (e.g. when
cloning).

EXAMPLE

$ git clone hg::http://selenic.com/repo/hello

CONFIGURATION

If you want to see Mercurial revisions as Git commit notes:

% git config core.notesRef refs/notes/hg

If you are not interested in Mercurial permanent and global branches (aka. commit labels):

% git config --global remote-hg.track-branches false

With this configuration, the branches/foo refs won’t appear.

If you want the equivalent of hg clone --insecure:

% git config --global remote-hg.insecure true

If you want git-remote-hg to be compatible with hg-git, and generate exactly the same
commits:

% git config --global remote-hg.hg-git-compat true

NOTES

Remember to run git gc --aggressive after cloning a repository, specially if it’s a big
one. Otherwise lots of space will be wasted.

The oldest version of Mercurial supported is 1.9. For the most part 1.8 works, but you
might experience some issues.

Pushing branches
To push a Mercurial named branch, you need to use the "branches/" prefix:

% git checkout branches/next
# do stuff
% git push origin branches/next

All the pushed commits will receive the "next" Mercurial named branch.

Note: Make sure you don’t have remote-hg.track-branches disabled.

Cloning HTTPS
The simplest way is to specify the user and password in the URL:

git clone hg::https://user:[email protected]/user/repo

You can also use the schemes extension:

[auth]
bb.prefix = https://bitbucket.org/user/
bb.username = user
bb.password = password

Finally, you can also use the keyring extension.

CAVEATS

The only major incompatibility is that Git octopus merges (a merge with more than two
parents) are not supported.

Mercurial branches and bookmarks have some limitations of Git branches: you can’t have
both dev/feature and dev (as Git uses files and directories to store them).

Multiple anonymous heads (which are useless anyway) are not supported; you would only see
the latest head.

Closed branches are not supported; they are not shown and you can’t close or reopen.
Additionally in certain rare situations a synchronization issue can occur (Bug #65).
