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

These are classified by approximate size: an hour or less, a day or
14
less, and several days or more.
20
* Add of a file that was present in the base revision should put back
23
* Handle diff of files which do not have a trailing newline; probably
24
requires patching difflib to get it exactly right, or otherwise
25
calling out to GNU diff.
27
* Import ElementTree update patch.
29
* Syntax should be ``bzr export -r REV``.
31
* Plugins that provide commands. By just installing a file into some
32
directory (e.g. ``/usr/share/bzr/plugins``) it should be possible to
33
create new top-level commands (``bzr frob``). Extensions can be
34
written in either Python (in which case they use the bzrlib API) or
35
in a separate process (in sh, C, whatever). It should be possible
36
to get help for plugin commands.
38
* Smart rewrap text in help messages to fit in $COLUMNS (or equivalent
41
* -r option should take a revision-id as well as a revno.
43
* ``bzr info`` could show space used by working tree, versioned files,
44
unknown and ignored files.
46
* ``bzr info`` should count only people with distinct email addresses as
47
different committers. (Or perhaps only distinct userids?)
49
* On Windows, command-line arguments should be `glob-expanded`__,
50
because the shell doesn't do this. However, there are probably some
51
commands where this shouldn't be done, such as 'bzr ignore', because
52
we want to accept globs.
54
* ``bzr ignore`` command that just adds a line to the ``.bzrignore`` file
55
and makes it versioned. Fix this to break symlinks.
57
* ``bzr help commands`` should give a one-line summary of each command.
59
* Any useful sanity checks in 'bzr ignore'? Perhaps give a warning if
60
they try to add a single file which is already versioned, or if they
61
add a pattern which already exists, or if it looks like they gave an

66
* Read and write locks on branch while it's open.
68
* Separate read and write version checks?
70
* ``bzr status FILE...``
72
* Check all commands have decent help.
74
* Autogenerate argument/option help.
76
* ``bzr inventory -r REV`` and perhaps unify this with ``bzr ls``,
77
giving options to display ids, types, etc.
79
* Atomic file class that renames into place when it's closed.
85
* Display command grammar in help messages rather than hardcoding it.
87
* Change command functions into Command() objects, like in hct, and
88
then the grammar can be described directly in there. Since all
89
option definitions are global we can define them just once and
90
reference them from each command.
92
* Selective commit of only some files.
96
Status should be handled differently because it needs to report on
97
deleted and unknown files. diff only needs to deal with versioned
100
* Merge Aaron's merge code.
102
* Merge revert patch.
104
* Turn on stat cache code, and add optimization about avoiding
105
dangerous cache entries.
107
* ``bzr mv`` that does either rename or move as in Unix.
109
* More efficient diff of only selected files.
111
* Fix up Inventory objects to represent root object as an entry.
113
* Don't convert entire entry from
115
* Extract changes from one revision to the next to a text form
116
suitable for transmission over email.
120
* Write a reproducible benchmark, perhaps importing various kernel versions.
122
* Change test.sh from Bourne shell into something in pure Python so
123
that it can be more portable.
125
* Directly import diffs! It seems a bit redundant to need to rescan
126
the directory to work out what files diff added/deleted/changed when
127
all the information is there in the diff in the first place.
128
Getting the exact behaviour for added/deleted subdirectories etc
131
At the very least we could run diffstat over the diff, or perhaps
132
read the status output from patch. Just knowing which files might
133
be modified would be enough to guide the add and commit.
135
Given this we might be able to import patches at 1/second or better.
137
* Get branch over http.
139
* Pull pure updates over http.
141
* revfile compression.
143
* Split inventory into per-directory files.
145
* Fix ignore file parsing:
147
- fnmatch is not the same as unix patterns
149
- perhaps add extended globs from rsh/rsync
151
- perhaps a pattern that matches only directories or non-directories
153
* Consider using Python logging library as well as/instead of
156
* Change to using gettext message localization.
158
* Make a clearer separation between internal and external bzrlib
159
interfaces. Make internal interfaces use protected names. Write at
160
least some documentation for those APIs, probably as docstrings.
162
Consider using ZopeInterface definitions for the external interface;
163
I think these are already used in PyBaz. They allow automatic
164
checking of the interface but may be unfamiliar to general Python
165
developers, so I'm not really keen.
167
* Commands to dump out all command help into a manpage or HTML file or
170
* Handle symlinks in the working directory; at the very least it
171
should be possible for them to be present and ignored/unknown
172
without causing assertion failures.
174
Eventually symlinks should be versioned.
176
* Allow init in a subdirectory to create a nested repository, but only
177
if the subdirectory is not already versioned. Perhaps also require
178
a ``--nested`` to protect against confusion.
188
* Generate annotations from current file relative to previous
191
- Is it necessary to store any kind of annotation where data was
194
* Update revfile_ format and make it active:
196
- Texts should be identified by something keyed on the revision, not
197
an individual text-id. This is much more useful for annotate I
198
think; we want to map back to the revision that last changed it.
200
- Access revfile revisions through the Tree/Store classes.
202
- Check them from check commands.

208
* Hooks for pre-commit, post-commit, etc.
210
Consider the security implications; probably should not enable hooks
211
for remotely-fetched branches by default.
213
* Pre-commit check. If this hook is defined, it needs to be handled
214
specially: create a temporary directory containing the tree as it
215
will be after the commit. This means excluding any ignored/unknown
216
files, and respecting selective commits. Run the pre-commit check
217
(e.g. compile and run test suite) in there.
221
* GUI (maybe in Python GTK+?)
223
* C library interface
225
* Expansion of $Id$ keywords within working files. Perhaps do this in
226
exports first as a simpler case because then we don't need to deal
227
with removing the tags on the way back in.
