hg-fastimport ------------- WARNING: this extension is incomplete and lightly tested. It is currently intended for Mercurial developers or particularly daring users. hg-fastimport is a Mercurial extension for importing Git's fast-import dumps into Mercurial. fast-import is a file format for representing the entire history of a version control repository. This file format was designed to make it easier to write tools which convert from foreign (non-Git) VCS repository formats into Git; such tools exist for CVS, Mercurial, Darcs, and Perforce. However, there's no reason Git should be the only VCS to read git-fast-import files; for example, Bazaar has a fastimport extension similar in scope and aim to hg-fastimport. (In fact, hg-fastimport draws heavily on the work done for bzr-fastimport.) The goal of hg-fastimport is to make it just as easy to populate a Mercurial repository from a fastimport dump as it is for Bazaar or Git. DEPENDENCIES ------------ hg-fastimport requires Mercurial 1.3. hg-fastimport depends on the python-fastimport library (which was extracted from bzr-fastimport). python-fastimport lives on launchpad.net at https://code.launchpad.net/python-fastimport To make the 'fastimport' package provided by python-fastimport available to hg-fastimport, you need to add the python-fastimport directory to PYTHONPATH, e.g. PYTHONPATH=$HOME/src/pyfastimport It should also be possible to install python-fastimport from cheeshop: $ easy_install install python-fastimport And most Linux distributions have it packaged. USAGE ----- To use hg-fastimport, add a line like fastimport = /path/to/hg-fastimport/hgfastimport to the [extensions] section of your hgrc. Don't forget to set PYTHONPATH as explained above. To import into a brand-new Mercurial repository: hg init new hg -R new fastimport FILE... where FILE... is a list of one or more fast-import dumps. TESTING ------- hg-fastimport uses Mercurial's own testing infrastructure, so you will need a copy of the Mercurial source handy. For example, I keep a clone of Mercurial "crew" in ~/src/hg-crew. To test hg-fastimport: cd tests ~/src/hg-crew/tests/run-tests.py --local FURTHER READING --------------- The fast-import format is documented in the git-fast-import(1) man page: http://www.kernel.org/pub/software/scm/git-core/docs/git-fast-import.html Tools to convert various version control repositories to fast-import format: http://cvs2svn.tigris.org/cvs2git.html (CVS) http://repo.or.cz/w/fast-export.git (Mercurial, Subversion) http://repo.or.cz/w/darcs2git.git (Darcs) AVAILABILITY ------------ You can get the latest copy of hg-fastimport from its public Mercurial repository: hg clone http://vc.gerg.ca/hg/hg-fastimport AUTHORS ------- original author: Paul Crowley <paul at lshift dot net> LShift Ltd derived from bzr-fastimport by: Ian Clatworthy <ian.clatworthy at internode dot on dot net> Canonical Ltd current maintainer: Greg Ward <greg-hg at gerg dot ca> contributors: Paul Aurich <paul at darkrain42 dot org> Jelmer Vernooij <jelmer at samba dot org> COPYRIGHT --------- Copyright (C) 2008 Canonical Ltd Copyright (C) 2008 LShift Ltd.
