Convert a Mercurial Repository to Git

Question

I\'ve already tried hg2git through fast-export and I\'ve already tried hg-git.

Both with no success. hg2git actually worked, but I had to ask a friend who runs a Uni

Answer 1

Here are all the pieces put together for a migration on Windows.

Prerequisites

• Git
• Mercurial or TortoiseHg
• Python 2.7 (3.x won't work)

During install, allow binding to .sh files.
Ensure that all tools are available in the PATH environment variable.

Migration

1. Open cmd.exe
2. mkdir c:\git_work
3. cd c:\git_work
4. git clone http://repo.or.cz/r/fast-export.git
   This creates folder: c:\git_work\fast-export\

5. Now you need mercurial libs for python. Either get them from here or do the following steps.
   Edit c:\git_work\fast-export\hg-fast-export.py:

   import sys # move this line up here
   # Add a new line that imports [mercurial libraries][2] from this zip:
   sys.path.append(r'C:\Program Files\TortoiseHg\library.zip')
   # ...above the old line:
   from mercurial import node
   

6. mkdir MyNewGitRepo

7. Copy content of fast-export to MyNewGitRepo, ignore .git*
8. hg-fast-import.sh -r c:\Path\To\MyOldHgRepo
9. If this fails with "Error: repository has at least one unnamed head..." call the last line with parameter: --force

10. Remove the migration scripts:

    git clean -n # see what would happen
    git clean -f # delete migration files
    

11. Restore missing files by resetting the index and working tree.

    git reset --hard
