See also various low-level TODOs in the source code. Try looking in
10
the list archive or on gmane.org for previous discussion of these
13
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
* Plugins that provide commands. By just installing a file into some
30
directory (e.g. ``/usr/share/bzr/plugins``) it should be possible to
31
create new top-level commands (``bzr frob``). Extensions can be
32
written in either Python (in which case they use the bzrlib API) or
33
in a separate process (in sh, C, whatever). It should be possible
34
to get help for plugin commands.
36
* Smart rewrap text in help messages to fit in $COLUMNS (or equivalent
39
* -r option should take a revision-id as well as a revno.
41
* ``bzr info`` could show space used by working tree, versioned files,
42
unknown and ignored files.
44
* ``bzr info`` should count only people with distinct email addresses as
45
different committers. (Or perhaps only distinct userids?)
47
* On Windows, command-line arguments should be `glob-expanded`__,
48
because the shell doesn't do this. However, there are probably some
49
commands where this shouldn't be done, such as 'bzr ignore', because
50
we want to accept globs.
52
* ``bzr ignore`` command that just adds a line to the ``.bzrignore`` file
53
and makes it versioned. Fix this to break symlinks.
55
* Any useful sanity checks in 'bzr ignore'? Perhaps give a warning if
56
they try to add a single file which is already versioned, or if they
57
add a pattern which already exists, or if it looks like they gave an

62
* Separate read and write version checks?
64
* ``bzr status DIR`` should give status on all files under that
67
* Check all commands have decent help.
69
* ``bzr inventory -r REV`` and perhaps unify this with ``bzr ls``,
70
giving options to display ids, types, etc.
72
* Atomic file class that renames into place when it's closed.
74
* Don't abort if ``~/.bzr.log`` can't be used.
76
* Split BzrError into various more specific subclasses for different
77
errors people might want to catch.
79
* If the export destination ends in '.tar', '.tar.gz', etc then create
80
a tarball instead of a directory. (Need to actually make a
81
temporary directory and then tar that up.)

85
* testbzr should by default test the bzr binary in the same directory
86
as the testbzr script, or take a path to it as a first parameter.
88
Should show the version from bzr and the path name.
93
* Display command grammar in help messages rather than hardcoding it.
95
* Change command functions into Command() objects, like in hct, and
96
then the grammar can be described directly in there. Since all
97
option definitions are global we can define them just once and
98
reference them from each command.
100
* Selective commit of only some files.
102
* Faster diff/status.
104
Status should be handled differently because it needs to report on
105
deleted and unknown files. diff only needs to deal with versioned
108
* Merge Aaron's merge code.
110
* Merge revert patch.
112
* Turn on stat cache code, and add optimization about avoiding
113
dangerous cache entries.
115
* ``bzr mv`` that does either rename or move as in Unix.
117
* More efficient diff of only selected files.
119
* Fix up Inventory objects to represent root object as an entry.
121
* Don't convert entire entry from
123
* Extract changes from one revision to the next to a text form
124
suitable for transmission over email.
128
* Write a reproducible benchmark, perhaps importing various kernel versions.
130
* Change test.sh from Bourne shell into something in pure Python so
131
that it can be more portable.
133
* Directly import diffs! It seems a bit redundant to need to rescan
134
the directory to work out what files diff added/deleted/changed when
135
all the information is there in the diff in the first place.
136
Getting the exact behaviour for added/deleted subdirectories etc
139
At the very least we could run diffstat over the diff, or perhaps
140
read the status output from patch. Just knowing which files might
141
be modified would be enough to guide the add and commit.
143
Given this we might be able to import patches at 1/second or better.
145
* Get branch over http.
147
* Pull pure updates over http.
149
* revfile compression.
151
* Split inventory into per-directory files.
153
* Fix ignore file parsing:
155
- fnmatch is not the same as unix patterns
157
- perhaps add extended globs from rsh/rsync
159
- perhaps a pattern that matches only directories or non-directories
161
* Consider using Python logging library as well as/instead of
164
* Commands should give some progress indication by default.
166
- But quieten this with ``--silent``.
168
* Change to using gettext message localization.
170
* Make a clearer separation between internal and external bzrlib
171
interfaces. Make internal interfaces use protected names. Write at
172
least some documentation for those APIs, probably as docstrings.
174
Consider using ZopeInterface definitions for the external interface;
175
I think these are already used in PyBaz. They allow automatic
176
checking of the interface but may be unfamiliar to general Python
177
developers, so I'm not really keen.
179
* Commands to dump out all command help into a manpage or HTML file or
182
* Handle symlinks in the working directory; at the very least it
183
should be possible for them to be present and ignored/unknown
184
without causing assertion failures.
186
Eventually symlinks should be versioned.
188
* Allow init in a subdirectory to create a nested repository, but only
189
if the subdirectory is not already versioned. Perhaps also require
190
a ``--nested`` to protect against confusion.
194
* More test framework:
196
- Class that describes the state of a working tree so we can just
199
* There are too many methods on Branch() that really manipulate the
200
WorkingTree. They should be moved across.
202
Also there are some methods which are duplicated on Tree and
203
Inventory objects, and it should be made more clear which ones are
204
proxies and which ones behave differently, and how.
206
* Try using XSLT to add some formatting to REST-generated HTML. Or
207
maybe write a small Python program that specifies a header and foot
208
for the pages and calls into the docutils libraries.
210
* --format=xml for log, status and other commands.
212
* Attempting to explicitly add a file that's already added should give
213
a warning; however there should be no warning for directories (since
214
we scan for new children) or files encountered in a directory that's
217
* Better handling of possible collisions on case-losing filesystems;
218
make sure a single file does not get added twice under different
221
* Clean up XML inventory:
223
- Use nesting rather than parent_id pointers.
225
- Hold the ElementTree in memory in the Inventory object and work
226
directly on that, rather than converting into Python objects every
227
time it is read in. Probably still expose it through some kind of
228
object interface though, but perhaps that should just be a proxy
231
- Less special cases for the root directory.
233
* Perhaps inventories should remember the revision in which each file
234
was last changed, as well as its current state? This is a bit
235
redundant but might often be interested to know.
241
* Generate annotations from current file relative to previous
244
- Is it necessary to store any kind of annotation where data was
247
* Update revfile_ format and make it active:
249
- Texts should be identified by something keyed on the revision, not
250
an individual text-id. This is much more useful for annotate I
251
think; we want to map back to the revision that last changed it.
253
- Access revfile revisions through the Tree/Store classes.
255
- Check them from check commands.

261
* Hooks for pre-commit, post-commit, etc.
263
Consider the security implications; probably should not enable hooks
264
for remotely-fetched branches by default.
266
* Pre-commit check. If this hook is defined, it needs to be handled
267
specially: create a temporary directory containing the tree as it
268
will be after the commit. This means excluding any ignored/unknown
269
files, and respecting selective commits. Run the pre-commit check
270
(e.g. compile and run test suite) in there.
274
* GUI (maybe in Python GTK+?)
276
* C library interface
278
* Expansion of $Id$ keywords within working files. Perhaps do this in
279
exports first as a simpler case because then we don't need to deal
280
with removing the tags on the way back in.
