# Bazaar Release Notes

## bzr 0.1.1

Released:

  2005-10-12

### Bug Fixes

- Fix problem in pulling over HTTP from machines that do not allow directories to be listed.

- Avoid harmless warning about invalid hash cache after upgrading branch format.

### Performance

- Avoid some unnecessary HTTP operations in branch and pull.

## bzr 0.1

Released:

  2005-10-11

### Notes

- ‘bzr branch’ over HTTP initially gives a very high estimate of completion time but it should fall as the first few revisions are pulled in. branch is still slow on high-latency connections.

### Bug Fixes

- bzr-man.py has been updated to work again. Contributed by Rob Weir.

- Locking is now done with fcntl.lockf which works with NFS file systems. Contributed by Harald Meland.

- When a merge encounters a file that has been deleted on one side and modified on the other, the old contents are written out to foo.BASE and foo.SIDE, where SIDE is this or OTHER. Contributed by Aaron Bentley.

- Export was choosing incorrect file paths for the content of the tarball, this has been fixed by Aaron Bentley.

- Commit will no longer commit without a log message, an error is returned instead. Contributed by Jelmer Vernooij.

- If you commit a specific file in a sub directory, any of its parent directories that are added but not listed will be automatically included. Suggested by Michael Ellerman.

- bzr commit and upgrade did not correctly record new revisions for files with only a change to their executable status. bzr will correct this when it encounters it. Fixed by Robert Collins

- HTTP tests now force off the use of `http_proxy` for the duration. Contributed by Gustavo Niemeyer.

- Fix problems in merging weave-based branches that have different partial views of history.

- Symlink support: working with symlinks when not in the root of a bzr tree was broken, patch from Scott James Remnant.

### Improvements

- ‘branch’ now accepts a –basis parameter which will take advantage of local history when making a new branch. This allows faster branching of remote branches. Contributed by Aaron Bentley.

- New tree format based on weave files, called version 5. Existing branches can be upgraded to this format using ‘bzr upgrade’.

- Symlinks are now versionable. Initial patch by Erik Toubro Nielsen, updated to head by Robert Collins.

- Executable bits are tracked on files. Patch from Gustavo Niemeyer.

- ‘bzr status’ now shows unknown files inside a selected directory. Patch from Heikki Paajanen.

- Merge conflicts are recorded in .bzr. Two new commands ‘conflicts’ and ‘resolve’ have needed added, which list and remove those merge conflicts respectively. A conflicted tree cannot be committed in. Contributed by Aaron Bentley.

- ‘rm’ is now an alias for ‘remove’.

- Stores now split out their content in a single byte prefixed hash, dropping the density of files per directory by 256. Contributed by Gustavo Niemeyer.

- ‘bzr diff -r branch:URL’ will now perform a diff between two branches. Contributed by Robert Collins.

- ‘bzr log’ with the default formatter will show merged revisions, indented to the right. Initial implementation contributed by Gustavo Niemeyer, made incremental by Robert Collins.

### Internals

- Test case failures have the exception printed after the log for your viewing pleasure.

- InventoryEntry is now an abstract base class, use one of the concrete InventoryDirectory etc classes instead.

- Branch raises an UnsupportedFormatError when it detects a bzr branch it cannot understand. This allows for precise handling of such circumstances.

- Remove RevisionReference class; `Revision.parent_ids` is now simply a list of their ids and `parent_sha1s` is a list of their corresponding sha1s (for old branches only at the moment.)

- New method-object style interface for Commit() and Fetch().

- Renamed `Branch.last_patch()` to `Branch.last_revision()`, since we call them revisions not patches.

- Move `copy_branch` to `bzrlib.clone.copy_branch`. The destination directory is created if it doesn’t exist.

- Inventories now identify the files which were present by giving the revision of that file.

- Inventory and Revision XML contains a version identifier. This must be consistent with the overall branch version but allows for more flexibility in future upgrades.

### Testing

- Removed testsweet module so that tests can be run after bzr installed by ‘bzr selftest’.

- ‘bzr selftest’ command-line arguments can now be partial ids of tests to run, e.g. `bzr selftest test_weave`

## bzr 0.0.9

Released:

  2005-09-23

### Bug Fixes

- Fixed “branch -r” option.

- Fix remote access to branches containing non-compressed history. (Robert Collins).

- Better reliability of HTTP server tests. (John Arbash-Meinel)

- Merge graph maximum distance calculation fix. (Aaron Bentley)

- Various minor bug in windows support have been fixed, largely in the test suite. Contributed by Alexander Belchenko.

### Improvements

- Status now accepts a -r argument to give status between chosen revisions. Contributed by Heikki Paajanen.

- Revision arguments no longer use +/-/= to control ranges, instead there is a ‘before’ namespace, which limits the successive namespace. For example ‘$ bzr log -r date:yesterday..before:date:today’ will select everything from yesterday and before today. Contributed by Robey Pointer

- There is now a bzr.bat file created by distutils when building on Windows. Contributed by Alexander Belchenko.

### Internals

- Removed uuid() as it was unused.

- Improved ‘fetch’ code for pulling revisions from one branch into another (used by pull, merged, etc.)

## bzr 0.0.8

Released:

  2005-09-20

### Improvements

- Adding a file whose parent directory is not versioned will implicitly add the parent, and so on up to the root. This means you should never need to explictly add a directory, they’ll just get added when you add a file in the directory. Contributed by Michael Ellerman.

- Ignore `.DS_Store` (contains Mac metadata) by default. (Nir Soffer)

- If you set `BZR_EDITOR` in the environment, it is checked in preference to EDITOR and the config file for the interactive commit editing program. Related to this is a bugfix where a missing program set in EDITOR would cause editing to fail, now the fallback program for the operating system is still tried.

- Files that are not directories/symlinks/regular files will no longer cause bzr to fail, it will just ignore them by default. You cannot add them to the tree though - they are not versionable.

### Internals

- Refactor XML packing/unpacking.

### Bug Fixes

- Fixed ‘bzr mv’ by Ollie Rutherfurd.

- Fixed strange error when trying to access a nonexistent HTTP branch.

- Make sure that the hashcache gets written out if it can’t be read.

### Portability

- Various Windows fixes from Ollie Rutherfurd.

- Quieten warnings about locking; patch from Matt Lavin.

## bzr-0.0.7

Released:

  2005-09-02

### New Features

- `bzr shell-complete` command contributed by Clint Adams to help with intelligent shell completion.

- New expert command `bzr find-merge-base` for debugging merges.

### Enhancements

- Much better merge support.

- merge3 conflicts are now reported with markers like ‘<<<<<<<’ (seven characters) which is the same as CVS and pleases things like emacs smerge.

### Bug Fixes

- `bzr upgrade` no longer fails when trying to fix trees that mention revisions that are not present.

- Fixed bugs in listing plugins from `bzr plugins`.

- Fix case of $EDITOR containing options for the editor.

- Fix log -r refusing to show the last revision. (Patch from Goffredo Baroncelli.)

### Changes

- `bzr log --show-ids` shows the revision ids of all parents.

- Externally provided commands on your $BZRPATH no longer need to recognize –bzr-usage to work properly, and can just handle –help themselves.

### Library

- Changed trace messages to go through the standard logging framework, so that they can more easily be redirected by libraries.

## bzr-0.0.6

Released:

  2005-08-18

### New Features

- Python plugins, automatically loaded from the directories on `BZR_PLUGIN_PATH` or `~/.bzr.conf/plugins` by default.

- New ‘bzr mkdir’ command.

- Commit mesage is fetched from an editor if not given on the command line; patch from Torsten Marek.

- `bzr log -m FOO` displays commits whose message matches regexp FOO.

- `bzr add` with no arguments adds everything under the current directory.

- `bzr mv` does move or rename depending on its arguments, like the Unix command.

- `bzr missing` command shows a summary of the differences between two trees. (Merged from John Arbash-Meinel.)

- An email address for commits to a particular tree can be specified by putting it into .bzr/email within a branch. (Based on a patch from Heikki Paajanen.)

### Enhancements

- Faster working tree operations.

### Changes

- 3rd-party modules shipped with bzr are copied within the bzrlib python package, so that they can be installed by the setup script without clashing with anything already existing on the system. (Contributed by Gustavo Niemeyer.)

- Moved plugins directory to bzrlib/, so that there’s a standard plugin directory which is not only installed with bzr itself but is also available when using bzr from the development tree. `BZR_PLUGIN_PATH` and `DEFAULT_PLUGIN_PATH` are then added to the standard plugins directory.

- When exporting to a tarball with `bzr export --format tgz`, put everything under a top directory rather than dumping it into the current directory. This can be overridden with the `--root` option. Patch from William Dodé and John Meinel.

- New `bzr upgrade` command to upgrade the format of a branch, replacing `bzr check --update`.

- Files within store directories are no longer marked readonly on disk.

- Changed `bzr log` output to a more compact form suggested by John A Meinel. Old format is available with the `--long` or `-l` option, patched by William Dodé.

- By default the commit command refuses to record a revision with no changes unless the `--unchanged` option is given.

- The `--no-plugins`, `--profile` and `--builtin` command line options must come before the command name because they affect what commands are available; all other options must come after the command name because their interpretation depends on it.

- `branch` and `clone` added as aliases for `branch`.

- Default log format is back to the long format; the compact one is available with `--short`.

### Bug Fixes

- Fix bugs in committing only selected files or within a subdirectory.

## bzr-0.0.5

Released:

  2005-06-15

### Changes

- `bzr` with no command now shows help rather than giving an error. Suggested by Michael Ellerman.

- `bzr status` output format changed, because svn-style output doesn’t really match the model of bzr. Now files are grouped by status and can be shown with their IDs. `bzr status --all` shows all versioned files and unknown files but not ignored files.

- `bzr log` runs from most-recent to least-recent, the reverse of the previous order. The previous behaviour can be obtained with the `--forward` option.

- `bzr inventory` by default shows only filenames, and also ids if `--show-ids` is given, in which case the id is the second field.

### Enhancements

- New ‘bzr whoami –email’ option shows only the email component of the user identification, from Jo Vermeulen.

- New `bzr ignore PATTERN` command.

- Nicer error message for broken pipe, interrupt and similar conditions that don’t indicate an internal error.

- Add `.*.sw[nop] .git .*.tmp *,v` to default ignore patterns.

- Per-branch locks keyed on `.bzr/branch-lock`, available in either read or write mode.

- New option `bzr log --show-ids` shows revision and file ids.

- New usage `bzr log FILENAME` shows only revisions that affected that file.

- Changed format for describing changes in `bzr log -v`.

- New option `bzr commit --file` to take a message from a file, suggested by LarstiQ.

- New syntax `bzr status [FILE...]` contributed by Bartosz Oler. File may be in a branch other than the working directory.

- `bzr log` and `bzr root` can be given an HTTP URL instead of a filename.

- Commands can now be defined by external programs or scripts in a directory on $BZRPATH.

- New “stat cache” avoids reading the contents of files if they haven’t changed since the previous time.

- If the Python interpreter is too old, try to find a better one or give an error. Based on a patch from Fredrik Lundh.

- New optional parameter `bzr info [BRANCH]`.

- New form `bzr commit SELECTED` to commit only selected files.

- New form `bzr log -r FROM:TO` shows changes in selected range; contributed by John A Meinel.

- New option `bzr diff --diff-options 'OPTS'` allows passing options through to an external GNU diff.

- New option `bzr add --no-recurse` to add a directory but not their contents.

- `bzr --version` now shows more information if bzr is being run from a branch.

### Bug Fixes

- Fixed diff format so that added and removed files will be handled properly by patch. Fix from Lalo Martins.

- Various fixes for files whose names contain spaces or other metacharacters.

### Testing

- Converted black-box test suites from Bourne shell into Python; now run using `./testbzr`. Various structural improvements to the tests.

- testbzr by default runs the version of bzr found in the same directory as the tests, or the one given as the first parameter.

- testbzr also runs the internal tests, so the only command required to check is just `./testbzr`.

- testbzr requires python2.4, but can be used to test bzr running under a different version.

- Tests added for many other changes in this release.

### Internal

- Included ElementTree library upgraded to 1.2.6 by Fredrik Lundh.

- Refactor command functions into Command objects based on HCT by Scott James Remnant.

- Better help messages for many commands.

- Expose `bzrlib.open_tracefile()` to start the tracefile; until this is called trace messages are just discarded.

- New internal function `find_touching_revisions()` and hidden command touching-revisions trace the changes to a given file.

- Simpler and faster `compare_inventories()` function.

- `bzrlib.open_tracefile()` takes a tracefilename parameter.

- New AtomicFile class.

- New developer commands `added`, `modified`.

### Portability

- Cope on Windows on python2.3 by using the weaker random seed. 2.4 is now only recommended.

## bzr-0.0.4

Released:

  2005-04-22

### Enhancements

- ‘bzr diff’ optionally takes a list of files to diff. Still a bit basic. Patch from QuantumG.

- More default ignore patterns.

- New ‘bzr log –verbose’ shows a list of files changed in the changeset. Patch from Sebastian Cote.

- Roll over ~/.bzr.log if it gets too large.

- Command abbreviations ‘ci’, ‘st’, ‘stat’, ‘?’ based on a patch by Jason Diamon.

- New ‘bzr help commands’ based on a patch from Denys Duchier.

### Changes

- User email is determined by looking at $BZREMAIL or ~/.bzr.email or $EMAIL. All are decoded by the locale preferred encoding. If none of these are present user@hostname is used. The host’s fully-qualified name is not used because that tends to fail when there are DNS problems.

- New ‘bzr whoami’ command instead of username user-email.

### Bug Fixes

- Make commit safe for hardlinked bzr trees.

- Some Unicode/locale fixes.

- Partial workaround for `difflib.unified_diff` not handling trailing newlines properly.

### Internal

- Allow docstrings for help to be in PEP0257 format. Patch from Matt Brubeck.

- More tests in test.sh.

- Write profile data to a temporary file not into working directory and delete it when done.

- Smaller .bzr.log with process ids.

### Portability

- Fix opening of ~/.bzr.log on Windows. Patch from Andrew Bennetts.

- Some improvements in handling paths on Windows, based on a patch from QuantumG.

## bzr-0.0.3

Released:

  2005-04-06

### Enhancements

- New “directories” internal command lists versioned directories in the tree.

- Can now say “bzr commit –help”.

- New “rename” command to rename one file to a different name and/or directory.

- New “move” command to move one or more files into a different directory.

- New “renames” command lists files renamed since base revision.

- New cat command contributed by janmar.

### Changes

- .bzr.log is placed in $HOME (not pwd) and is always written in UTF-8. (Probably not a completely good long-term solution, but will do for now.)

### Portability

- Workaround for difflib bug in Python 2.3 that causes an exception when comparing empty files. Reported by Erik Toubro Nielsen.

### Internal

- Refactored inventory storage to insert a root entry at the top.

### Testing

- Start of shell-based black-box testing in test.sh.

## bzr-0.0.2.1

### Portability

- Win32 fixes from Steve Brown.

## bzr-0.0.2

Codename:

  “black cube”

Released:

  2005-03-31

### Enhancements

- Default ignore list extended (see bzrlib/__init__.py).

- Patterns in .bzrignore are now added to the default ignore list, rather than replacing it.

- Ignore list isn’t reread for every file.

- More help topics.

- Reinstate the ‘bzr check’ command to check invariants of the branch.

- New ‘ignored’ command lists which files are ignored and why; ‘deleted’ lists files deleted in the current working tree.

- Performance improvements.

- New global –profile option.

- Ignore patterns like ‘./config.h’ now correctly match files in the root directory only.

## bzr-0.0.1

Released:

  2005-03-26

### Enhancements

- More information from info command.

- Can now say “bzr help COMMAND” for more detailed help.

- Less file flushing and faster performance when writing logs and committing to stores.

- More useful verbose output from some commands.

- Fix inverted display of ‘R’ and ‘M’ during ‘commit -v’.

### Portability

- Include a subset of ElementTree-1.2.20040618 to make installation easier.

- Fix time.localtime call to work with Python 2.3 (the minimum supported).

## bzr-0.0.0.69

Released:

  2005-03-22

### Enhancements

- First public release.

- Storage of local versions: init, add, remove, rm, info, log, diff, status, etc.
