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
* Syntax should be "bzr export -r REV".
33
* Plugins that provide commands. By just installing a file into some
34
directory (e.g. /usr/share/bzr/plugins) it should be possible to
35
create new top-level commands ("bzr frob"). Extensions can be
36
written in either Python (in which case they use the bzrlib API) or
37
in a separate process (in sh, C, whatever). It should be possible
38
to get help for plugin commands.
40
* Smart rewrap text in help messages to fit in $COLUMNS (or equivalent
43
* -r option should take a revision-id as well as a revno.
45
* "bzr info" could show space used by working tree, versioned files,
46
unknown and ignored files.
48
* "bzr info" should count only people with distinct email addresses as
49
different committers. (Or perhaps only distinct userids?)
51
* Tidier error for EPIPE: should be just "bzr: broken pipe" with no
52
other details because debugging information is rarely interesting.
54
* On Windows, command-line arguments should be glob-expanded__,
55
because the shell doesn't do this. However, there are probably some
56
commands where this shouldn't be done, such as 'bzr ignore', because
57
we want to accept globs.

61
* 'bzr ignore' command that just adds a line to the .bzrignore file
62
and makes it versioned.
64
* 'bzr help commands' should give a one-line summary of each command.
66
* Any useful sanity checks in 'bzr ignore'? Perhaps give a warning if
67
they try to add a single file which is already versioned, or if they
68
add a pattern which already exists, or if it looks like they gave an
74
* Display command grammar in help messages rather than hardcoding it.
76
* Change command functions into Command() objects, like in hct, and
77
then the grammar can be described directly in there. Since all
78
option definitions are global we can define them just once and
79
reference them from each command.
81
* Selective commit of only some files.
85
Status should be handled differently because it needs to report on
86
deleted and unknown files. diff only needs to deal with versioned
89
* Merge Aaron's merge code.
93
* Turn on stat cache code, and add optimization about avoiding
94
dangerous cache entries.
98
* More efficient diff of only selected files.
100
* Fix up Inventory objects to represent root object as an entry.
102
* Don't convert entire entry from
104
* Extract changes from one revision to the next to a text form
105
suitable for transmission over email.
109
* Write a reproducible benchmark, perhaps importing various kernel versions.
111
* Change test.sh from Bourne shell into something in pure Python so
112
that it can be more portable.
114
* Directly import diffs! It seems a bit redundant to need to rescan
115
the directory to work out what files diff added/deleted/changed when
116
all the information is there in the diff in the first place.
117
Getting the exact behaviour for added/deleted subdirectories etc
120
At the very least we could run diffstat over the diff, or perhaps
121
read the status output from patch. Just knowing which files might
122
be modified would be enough to guide the add and commit.
124
Given this we might be able to import patches at 1/second or better.
126
* Get branch over http.
128
* Pull pure updates over http.
130
* revfile compression.
132
* Split inventory into per-directory files.
134
* Fix ignore file parsing:
136
- fnmatch is not the same as unix patterns
138
- perhaps add extended globs from rsh/rsync
140
- perhaps a pattern that matches only directories or non-directories
142
* Consider using Python logging library as well as/instead of
145
* Change to using gettext message localization.
147
* Make a clearer separation between internal and external bzrlib
148
interfaces. Make internal interfaces use protected names. Write at
149
least some documentation for those APIs, probably as docstrings.
151
Consider using ZopeInterface definitions for the external interface;
152
I think these are already used in PyBaz. They allow automatic
153
checking of the interface but may be unfamiliar to general Python
154
developers, so I'm not really keen.
156
* Commands to dump out all command help into a manpage or HTML file or
163
* Generate annotations from current file relative to previous
166
- Is it necessary to store any kind of annotation where data was
169
* Update revfile format and make it active:
171
- Texts should be identified by something keyed on the revision, not
172
an individual text-id. This is much more useful for annotate I
173
think; we want to map back to the revision that last changed it.
175
- Access revfile revisions through the Tree/Store classes.
177
- Check them from check commands.
181
* Hooks for pre-commit, post-commit, etc.
183
Consider the security implications; probably should not enable hooks
184
for remotely-fetched branches by default.
186
* Pre-commit check. If this hook is defined, it needs to be handled
187
specially: create a temporary directory containing the tree as it
188
will be after the commit. This means excluding any ignored/unknown
189
files, and respecting selective commits. Run the pre-commit check
190
(e.g. compile and run test suite) in there.
194
* GUI (maybe in Python GTK+?)
196
* C library interface
198
* Expansion of $Id$ keywords within working files. Perhaps do this in
199
exports first as a simpler case because then we don't need to deal
200
with removing the tags on the way back in.
