2 bzr-fastimport Release Notes
3 ============================
12 * bzr-fastimport's file parsing and generation functionality has been exported into
13 separate upstream project called python-fastimport, that it now depends on.
14 python-fastimport can be retrieved from http://launchpad.net/python-fastimport.
19 * Cope with non-ascii characters in tag names. (Jelmer Vernooij, #598060)
21 * Cope with non-ascii characters in symbolic links. (Daniel Clemente,
22 Jelmer Vernooij, #238365)
24 * In plain mode, don't export multiple authors. (David Kilzer, #496677)
26 * Fix indentation when starting p4 fails. (Jelmer Vernooij)
28 * SOURCE argument to bzr fast-import-filter is now optional, consistent with
29 examples. (Jelmer Vernooij, #477861)
31 * Support new marks file format introduced in (apparently) git 1.6.
32 (Ian Clatworthy, Jelmer Vernooij, Gabriel Filion, #347729)
34 * Allow entries without email address in user map. (Jelmer Vernooij, #576598)
36 * Strip leading slashes when exporting Subversion repositories.
37 (Jelmer Vernooij, #477869)
45 * The fast-import command now takes an optional but recommended
46 DESTINATION argument. A repository will be created at this
47 location and branches will be created within there. If the user
48 is running bzr 1.17 up to 2.0, format "2a" is used for these,
49 otherwise the default format is used. A format can be explicitly
50 given using the new --format option. (Ian Clatworthy)
52 * Wrapper commands simplifying the generation of fast-import
53 files from other tools are now provided. The general usage is:
55 bzr fast-export-from-xxx SOURCE project.fi
57 Before starting an export, these commands make an effort to
58 check that dependent tools are installed. So far, wrapper
59 commands are available for cvs, darcs, git, hg (Mercurial),
60 mnt (Monotone), p4 (Perforce) and svn (Subversion).
61 (Ian Clatworthy, Matt McClure)
63 * darcs-fast-export is now bundled. In fact, the project has
64 merged into this one for the purposes of ongoing bug fixing
65 and development. (Miklos Vajna)
67 * fast-export now supports a --no-plain parameter which causes
68 richer metadata to be included in the output using the
69 recently agreed 'feature' extension capability. The features
70 used are called multiple-authors, commit-properties and
71 empty-directories. (Ian Clatworthy)
73 * fast-import and fast-import-filter now support user mapping
74 via the new --user-map option. The argument is a file specifying
75 how user-ids should be mapped to preferred user-ids.
78 * svn-fast-export now supports an address option (to control the
79 default email domain) and a first-rev option (to select revisions
80 since a given one). (Ted Gould)
85 * Large repositories now compress better thanks to a change in
86 how file-ids are assigned. (Ian Clatworthy, John Arbash Meinel)
88 * Memory usage is improved by flushing blobs to a disk cache
89 when appropriate. (John Arbash Meinel)
91 * If a fast-import source ends in ".gz", it is assumed to be in
92 gzip format and the stream is implicitly uncompressed. This
93 means fast-import dump files generated by fast-export-from-xxx
94 can be stored gzipped to save space. (Ian Clatworthy)
96 * The working tree is now implicitly updated for trunk. Other
97 branches still need to be explicitly created using 'bzr update'.
100 * Directories that become empty following a delete or rename of
101 one of their children are now implicitly pruned. If required,
102 this will be made optional at a later date.
103 (Tom Widmer, Ian Clatworthy)
105 * Blob tracking is now more intelligently done by an implicit
106 first pass to collect blob usage statistics. This eliminates
107 the need for an explicit 2-step process in all cases except
108 where stdin is used as the input source. (Ian Clatworthy)
110 * Updated the bundled version of hg-fast-export to be the latest
111 code (25-May-2009) from http://repo.or.cz/w/fast-export.git.
117 * Fixed the format used to create branches in a shared repository.
118 It now selects the best branch format based on the repository
119 format, rather than assume the default branch format is the right
120 one. (Ian Clatworthy)
122 * Fixed inventory delta generation when deleting directories.
123 (Previously the child paths included were relative to the
124 directory when they ought to be relative to the root.)
127 * Gracefully handle email addresses with unicode characters.
130 * Gracefully handle an empty input stream. (Gonéri Le Bouder)
132 * Gracefully handle git submodules by ignoring them.
135 * Get git-bzr working again. (Gonéri Le Bouder)
140 * Improved documentation has been published in the Bazaar Data Migration
141 Guide: http://doc.bazaar-vcs.org/migration/en/data-migration/.
150 * ``exporters/bzr-fast-export`` has been replaced with a
151 ``fast-export`` command. Some minor issues have been
152 fixed at the same time: the first commit now goes into
153 refs/heads/master (not refs/head/tmp); there's no
154 checkpoint at the top of the stream; parent commits are
155 now always given lower mark numbers than the commits they
156 are merged into. (Ian Clatworthy)
158 * The ``fast-import`` command now uses a different mapping of
159 git reference names to bzr branch names. In summary:
161 * ``refs/heads/foo`` is mapped to ``foo``
162 * ``refs/remotes/origin/foo`` is mapped to ``foo.remote``
163 * ``refs/tags/foo`` is mapped to ``foo.tag``
164 * ``*/master`` is mapped to ``trunk``, ``trunk.remote``, etc.
165 * ``*/trunk`` is mapped to ``git-trunk``, ``git-trunk.remote``, etc.
167 This new mapping has been introduced so that more natural
168 branch names are used and to enable round-tripping back to git.
171 * The old ``fast-import-filter`` command is now called
172 ``fast-import-query``. ``fast-import-filter`` now
173 really filters the input to produce a fast-import stream
174 based on filtering criteria. See below.
177 * The ``--inv-fulltext`` option is no longer supported. It was
178 only used in experimental mode for old versions of bzrlib so
179 it added more complexity than value. (Ian Clatworthy)
184 * Added ``fast-import-filter`` command for splitting out a
185 subdirectory or bunch of files into their own project. It can
186 also be used to create a new repository without any history
187 for nominated files and directories. This is useful for
188 removing information which is a security risk, huge binary
189 files like ISO images, etc.
192 * Copying of files and symbolic links is now supported.
195 * Initial cut at reset support. (Brian de Alwis, Ian Clatworthy)
200 * If ``refs/heads/xxx`` and ``refs/remotes/origin/xxx`` are both
201 defined, the latter is now mapped to a bzr branch called
202 ``xxx.remote`` rather than ``remotes--origins--xxx``.
205 * ``bzr fast-import-info`` now handles an unlimited # of parents for a
206 revision. The spec suggests the maximum ought to be 16 but the linux
207 kernel has revisions with more than that.
210 * ``bzr fast-import-info`` now reports on things that may need caching,
211 i.e. merges, rename old paths and copy source paths.
214 * Tag commands with a missing from clause now produce a warning but
215 are otherwise ignored. (Scott James Remnant, Ian Clatworthy)
217 * The fastimport-id-map file can now have more revisions than the
218 repository. (Scott James Remnant)
220 * Updated the bundled version of hg-fast-export to be the latest
221 code from http://repo.or.cz/w/fast-export.git. It should now
222 support recent Mercurial releases.
223 (Ian Clatworthy, #318903)
228 * Fixed a *bad* bug where filecopy commands were being parsed
229 as filerename commands. Repositories generated by previous
230 version of bzr-fast-import where the input stream contained
231 filecopy commands might be missing data (the copy source will
232 no longer be there if it was unchanged since the copy happened)
233 and ought to be regenerated.
236 * Fixed how the per-file graph is generated. The per-file graph
237 may still be less than perfect in the case where a file is only
238 changed in a merge and not the parent, but in the vast majority
239 of cases now, ``bzr check`` should no longer report inconsistent
240 parents. (Ian Clatworthy)
242 * Fix ``os`` import as needed on Windows.
243 (Ian Clatworthy, esskov, #264988)
245 * Handle a directory turning into a file and then the children
246 of that directory being deleted.
247 (Ian Clatworthy, #309486)
249 * Handle an empty email section.
252 * Handle multiple merges within the one merge clause. That's illegal
253 according to the spec but git-fast-export does it.
254 (Ian Clatworthy, #259711)
256 * Handle names and paths that aren't utf8 encoded. The spec recommends
257 utf8 encoding of these but git-fast-export doesn't always do that.
258 (Ian Clatworthy, #289088)
260 * Ignore lightweight tags with no from clause rather than abort.
261 (It seems git-fast-export outputs these commands frequently now
262 while it didn't appear to in early versions.)
263 (Ian Clatworthy, edice, #259711)
265 * Import into rich-root (and subtree) repositories without aborting.
266 (Ian Clatworthy, #300921)
268 * Recursively delete children when a directory is deleted.
269 (Scott James Remnant)
271 * The ``deleteall`` command now only tries to delete files in the
272 nominated branch, not all known files. As a consequence,
273 it should now be possible (if it wasn't before) to import
274 multiple Darcs branches (via darcs-fast-export) at once.
280 * A large number of tests have been added.
286 * Refactored ``processors/generic_processor.py`` into a bunch of modules.
296 * bzr-fast-export.py renamed to bzr-fast-export.
302 * Add support for the deleteall command.
303 (Miklos Vajna, #284941)
308 * bzr-fast-export now exports rm+mv correctly.
311 * Fix recursive rename handling in bzr-fast-export.
312 (Pieter de Bie, #287785)
314 * hg-fast-export should use binary mode on Windows.
317 * setup.py no longer assumes python2.4.
320 * setup.py support fixed.
323 * Update the last-modified revision for a renamed file.
333 * Added NEWS containing Release Notes. (Ian Clatworthy)
335 * ``bzr help fastimport`` now provides help that is useful.
338 * Numerous fixes to ``bzr-fast-export.py`` to improve round-tripping
339 with Git. Added ``--import-marks`` and ``--export-marks`` options
340 to ``fast-import`` as well.
343 * ``svn-fast-export.py`` now supports a regular-expression to specify
344 the branches to export.
350 * Support the new Repository API added in bzr.dev r3510. The old API
351 will be used for earlier versions of bzr including bzr 1.6beta2 and
352 earlier. (Ian Clatworthy)
357 * The ``--inv-fulltext`` option is not yet supported when the new
358 Repository API is used to import revisions. The option can be
359 provided but it will be ignored. (Ian Clatworthy)
363 * The ``RevisionLoader`` class has been renamed to ``RevisionLoader1``.
364 The ``ExperimentalRevisionLoader`` class has been renamed to
365 ``ImportRevisionLoader1``. New classes called ``RevisionLoader2``
366 and ``ImportRevisionLoader2`` are provided that use the new
367 Repository API. (Ian Clatworthy)
372 * Improved packaging by adding a setup.py file. (Ian Clatworthy)
378 * Version suitable for Bazaar 1.5.
