See also various low-level TODOs in the source code.  Try looking in

the list archive or on gmane.org for previous discussion of these

issues.

These are classified by approximate size: an hour or less, a day or

less, and several days or more.

Small things

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

* Add of a file that was present in the base revision should put back

  the previous file-id.

* Handle diff of files which do not have a trailing newline; probably

  requires patching difflib to get it exactly right, or otherwise

  calling out to GNU diff.

* Import ElementTree update patch.

* Syntax should be "bzr export -r REV".

* "cat -rREV FILE"

* Plugins that provide commands.  By just installing a file into some

  directory (e.g. /usr/share/bzr/plugins) it should be possible to

  create new top-level commands ("bzr frob").  Extensions can be

  written in either Python (in which case they use the bzrlib API) or

  in a separate process (in sh, C, whatever).   It should be possible

  to get help for plugin commands.

* Smart rewrap text in help messages to fit in $COLUMNS (or equivalent

  on Windows)

* -r option should take a revision-id as well as a revno.

* "bzr info" could show space used by working tree, versioned files,

  unknown and ignored files. 

* "bzr info" should count only people with distinct email addresses as

  different committers.  (Or perhaps only distinct userids?)

* Tidier error for EPIPE: should be just "bzr: broken pipe" with no

  other details because debugging information is rarely interesting.

* On Windows, command-line arguments should be glob-expanded__,

  because the shell doesn't do this.  However, there are probably some

  commands where this shouldn't be done, such as 'bzr ignore', because

  we want to accept globs.

__ http://mail.python.org/pipermail/python-list/2001-April/037847.html

* 'bzr ignore' command that just adds a line to the .bzrignore file

  and makes it versioned.

* 'bzr help commands' should give a one-line summary of each command.

* Any useful sanity checks in 'bzr ignore'?  Perhaps give a warning if

  they try to add a single file which is already versioned, or if they

  add a pattern which already exists, or if it looks like they gave an

  unquoted glob.

Medium things

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

* Display command grammar in help messages rather than hardcoding it.

* Change command functions into Command() objects, like in hct, and

  then the grammar can be described directly in there.  Since all

  option definitions are global we can define them just once and

  reference them from each command.

* Selective commit of only some files.

* Faster diff/status.  

  Status should be handled differently because it needs to report on

  deleted and unknown files.  diff only needs to deal with versioned

  files.

* Merge Aaron's merge code.

* Merge revert patch.

* Turn on stat cache code, and add optimization about avoiding

  dangerous cache entries.

* mv command?

* More efficient diff of only selected files.

* Fix up Inventory objects to represent root object as an entry.

* Don't convert entire entry from 

* Extract changes from one revision to the next to a text form

  suitable for transmission over email.

* More test cases.

* Write a reproducible benchmark, perhaps importing various kernel versions.

* Change test.sh from Bourne shell into something in pure Python so

  that it can be more portable.

* Directly import diffs!  It seems a bit redundant to need to rescan

  the directory to work out what files diff added/deleted/changed when

  all the information is there in the diff in the first place.

  Getting the exact behaviour for added/deleted subdirectories etc

  might be hard.

  At the very least we could run diffstat over the diff, or perhaps

  read the status output from patch.  Just knowing which files might

  be modified would be enough to guide the add and commit.

  Given this we might be able to import patches at 1/second or better.

* Get branch over http.

* Pull pure updates over http.

* revfile compression.

* Split inventory into per-directory files.

* Fix ignore file parsing:

  - fnmatch is not the same as unix patterns

  - perhaps add extended globs from rsh/rsync

  - perhaps a pattern that matches only directories or non-directories

* Expansion of $Id$ keywords within working files.  Perhaps do this in

  exports first as a simpler case because then we don't need to deal

  with removing the tags on the way back in.

* Consider using Python logging library as well as/instead of

  bzrlib.trace.

* Change to using gettext message localization.

Large things

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

* Hooks for pre-commit, post-commit, etc.

  Consider the security implications; probably should not enable hooks

  for remotely-fetched branches by default.

* Pre-commit check.  If this hook is defined, it needs to be handled

  specially: create a temporary directory containing the tree as it

  will be after the commit.  This means excluding any ignored/unknown

  files, and respecting selective commits.  Run the pre-commit check

  (e.g. compile and run test suite) in there.

* Web interface

* GUI (maybe in Python GTK+?)

* C library interface
