In Development

==============

Compatability Breaks

--------------------

New Features

------------

* darcs-fast-export is now bundled. In fact, the project has

  merged into this one for the purposes of ongoing bug fixing

  and development. (Miklos Vajna)

Improvements

------------

# Directories that become empty following a delete or rename of

  one of their children are now implicitly pruned. If required,

  this will be made optional at a later date.

  (Ian Clatworthy)

* Updated the bundled version of hg-fast-export to be the latest

  code (25-May-2009) from http://repo.or.cz/w/fast-export.git.

  (Ian Clatworthy)

Bug Fixes

---------

* Fixed the format used to create branches in a shared repository.

  It now selects the best branch format based on the repository

  format, rather than assume the default branch format is the right

  one. (Ian Clatworthy)

* Fixed inventory delta generation when deleting directories.

  (Previously the child paths included were relative to the

  directory when they ought to be relative to the root.)

  (Ian Clatworthy)

* Gracefully handle email addresses with unicode characters.

0.8 22-Jul-2009

===============

Compatibility Breaks

--------------------

* ``exporters/bzr-fast-export`` has been replaced with a

  ``fast-export`` command. Some minor issues have been

  fixed at the same time: the first commit now goes into

  refs/heads/master (not refs/head/tmp); there's no

  checkpoint at the top of the stream; parent commits are

  now always given lower mark numbers than the commits they

  are merged into. (Ian Clatworthy)

* The ``fast-import`` command now uses a different mapping of

  git reference names to bzr branch names. In summary:

  * ``refs/heads/foo`` is mapped to ``foo``

  * ``refs/remotes/origin/foo`` is mapped to ``foo.remote``

  * ``refs/tags/foo`` is mapped to ``foo.tag``

  * ``*/master`` is mapped to ``trunk``, ``trunk.remote``, etc.

  * ``*/trunk`` is mapped to ``git-trunk``, ``git-trunk.remote``, etc.

  This new mapping has been introduced so that more natural

  branch names are used and to enable round-tripping back to git.

  (Ian Clatworthy)

* The old ``fast-import-filter`` command is now called

  ``fast-import-query``. ``fast-import-filter`` now

  really filters the input to produce a fast-import stream

  based on filtering criteria. See below.

  (Ian Clatworthy)

* The ``--inv-fulltext`` option is no longer supported. It was

  only used in experimental mode for old versions of bzrlib so

  it added more complexity than value. (Ian Clatworthy)

New Features

------------

* Added ``fast-import-filter`` command for splitting out a

  subdirectory or bunch of files into their own project. It can

  also be used to create a new repository without any history

  for nominated files and directories. This is useful for

  removing information which is a security risk, huge binary

  files like ISO images, etc.

  (Ian Clatworthy)

* Copying of files and symbolic links is now supported.

  (Ian Clatworthy)

* Initial cut at reset support. (Brian de Alwis, Ian Clatworthy)

Improvements

------------

* If ``refs/heads/xxx`` and ``refs/remotes/origin/xxx`` are both

  defined, the latter is now mapped to a bzr branch called

  ``xxx.remote`` rather than ``remotes--origins--xxx``.

  (Ian Clatworthy)

* ``bzr fast-import-info`` now handles an unlimited # of parents for a

  revision. The spec suggests the maximum ought to be 16 but the linux

  kernel has revisions with more than that.

  (Ian Clatworthy)

* ``bzr fast-import-info`` now reports on things that may need caching,

  i.e. merges, rename old paths and copy source paths.

  (Ian Clatworthy)

* Tag commands with a missing from clause now produce a warning but

  are otherwise ignored. (Scott James Remnant, Ian Clatworthy)

* The fastimport-id-map file can now have more revisions than the

  repository. (Scott James Remnant)

* Updated the bundled version of hg-fast-export to be the latest

  code from http://repo.or.cz/w/fast-export.git. It should now

  support recent Mercurial releases.

  (Ian Clatworthy, #318903)

Bug Fixes

---------

* Fixed a *bad* bug where filecopy commands were being parsed

  as filerename commands. Repositories generated by previous

  version of bzr-fast-import where the input stream contained

  filecopy commands might be missing data (the copy source will

  no longer be there if it was unchanged since the copy happened)

  and ought to be regenerated.

  (Ian Clatworthy)

* Fixed how the per-file graph is generated. The per-file graph

  may still be less than perfect in the case where a file is only

  changed in a merge and not the parent, but in the vast majority

  of cases now, ``bzr check`` should no longer report inconsistent

  parents. (Ian Clatworthy)

* Fix ``os`` import as needed on Windows.

  (Ian Clatworthy, esskov, #264988)

* Handle a directory turning into a file and then the children

  of that directory being deleted.

  (Ian Clatworthy, #309486)

* Handle an empty email section.

  (Ian Clatworthy)

* Handle multiple merges within the one merge clause. That's illegal

  according to the spec but git-fast-export does it.

  (Ian Clatworthy, #259711)

* Handle names and paths that aren't utf8 encoded. The spec recommends

  utf8 encoding of these but git-fast-export doesn't always do that.

  (Ian Clatworthy, #289088)

* Ignore lightweight tags with no from clause rather than abort.

  (It seems git-fast-export outputs these commands frequently now

  while it didn't appear to in early versions.)

  (Ian Clatworthy, edice, #259711)

* Import into rich-root (and subtree) repositories without aborting.

  (Ian Clatworthy, #300921)

* Recursively delete children when a directory is deleted.

  (Scott James Remnant)

* The ``deleteall`` command now only tries to delete files in the

  nominated branch, not all known files. As a consequence,

  it should now be possible (if it wasn't before) to import

  multiple Darcs branches (via darcs-fast-export) at once.

  (Ian Clatworthy)

Testing

-------

* A large number of tests have been added.

  (Ian Clatworthy)

Internals

---------

* Refactored ``processors/generic_processor.py`` into a bunch of modules.

  (Ian Clatworthy)

0.7 09-Feb-2009

===============

Compatibility Breaks

--------------------

* bzr-fast-export.py renamed to bzr-fast-export.

  (Jelmer Vernooij)

Improvements

------------

* Add support for the deleteall command.

  (Miklos Vajna, #284941)

Bug Fixes

---------

* bzr-fast-export now exports rm+mv correctly.

  (Jonas)

* Fix recursive rename handling in bzr-fast-export.

  (Pieter de Bie, #287785)

* hg-fast-export should use binary mode on Windows.

  (Alexey Stukalov)

* setup.py no longer assumes python2.4.

  (schickb@gmail.com)

* setup.py support fixed.

  (Jelmer Vernooij)

* Update the last-modified revision for a renamed file.

  (John Arbash Meinel)

0.6 23-Jul-2008

===============

Improvements

------------

* Added NEWS containing Release Notes. (Ian Clatworthy)

* ``bzr help fastimport`` now provides help that is useful.

  (Ian Clatworthy)

* Numerous fixes to ``bzr-fast-export.py`` to improve round-tripping

  with Git. Added ``--import-marks`` and ``--export-marks`` options

  to ``fast-import`` as well.

  (Pieter de Bie)

* ``svn-fast-export.py`` now supports a regular-expression to specify

  the branches to export.

  (Mirko Friedenhagen)

Bug Fixes

---------

* Support the new Repository API added in bzr.dev r3510. The old API

  will be used for earlier versions of bzr including bzr 1.6beta2 and

  earlier. (Ian Clatworthy)

Compatibility Breaks

--------------------

* The ``--inv-fulltext`` option is not yet supported when the new

  Repository API is used to import revisions. The option can be

  provided but it will be ignored. (Ian Clatworthy)

API Breaks

* The ``RevisionLoader`` class has been renamed to ``RevisionLoader1``.

  The ``ExperimentalRevisionLoader`` class has been renamed to

  ``ImportRevisionLoader1``. New classes called ``RevisionLoader2``

  and ``ImportRevisionLoader2`` are provided that use the new

  Repository API. (Ian Clatworthy)

Internals

---------

* Improved packaging by adding a setup.py file. (Ian Clatworthy)

0.5 02-Jun-2008

===============

* Version suitable for Bazaar 1.5.

  (Ian Clatworthy)
