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
* 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
* ``bzr log DIR`` should give changes to any files within DIR.
69
* Check all commands have decent help.
71
* ``bzr inventory -r REV`` and perhaps unify this with ``bzr ls``,
72
giving options to display ids, types, etc.
74
* Atomic file class that renames into place when it's closed.
76
* Don't abort if ``~/.bzr.log`` can't be used.
78
* Split BzrError into various more specific subclasses for different
79
errors people might want to catch.
81
* If the export destination ends in '.tar', '.tar.gz', etc then create
82
a tarball instead of a directory. (Need to actually make a
83
temporary directory and then tar that up.)

87
* RemoteBranch could maintain a cache either in memory or on disk. We
88
know more than an external cache might about which files are
89
immutable and which can vary. On the other hand, it's much simpler
90
to just use an external proxy cache.
92
* Maybe also store directories in the statcache so that we can quickly
93
identify that they still exist.
99
* Change command functions into Command() objects, like in hct, and
100
then the grammar can be described directly in there. Since all
101
option definitions are global we can define them just once and
102
reference them from each command.
104
* Merge Aaron's merge code.
106
* Merge revert patch.
108
* ``bzr mv`` that does either rename or move as in Unix.
110
* More efficient diff of only selected files. We should be able to
111
just get the id for the selected files, look up their location and
112
diff just those files. No need to traverse the entire inventories.
114
* ``bzr status DIR`` or ``bzr diff DIR`` should report on all changes
115
under that directory.
117
* Fix up Inventory objects to represent root object as an entry.
119
* Don't convert entire entry from
121
* Extract changes from one revision to the next to a text form
122
suitable for transmission over email.
126
- Selected-file commit
128
- Impossible selected-file commit: adding things in non-versioned
129
directories, crossing renames, etc.
131
* Write a reproducible benchmark, perhaps importing various kernel versions.
133
* Change test.sh from Bourne shell into something in pure Python so
134
that it can be more portable.
136
* Directly import diffs! It seems a bit redundant to need to rescan
137
the directory to work out what files diff added/deleted/changed when
138
all the information is there in the diff in the first place.
139
Getting the exact behaviour for added/deleted subdirectories etc
142
At the very least we could run diffstat over the diff, or perhaps
143
read the status output from patch. Just knowing which files might
144
be modified would be enough to guide the add and commit.
146
Given this we might be able to import patches at 1/second or better.
148
* Get branch over http.
150
* Pull pure updates over http.
152
* revfile compression.
154
* Split inventory into per-directory files.
156
* Fix ignore file parsing:
158
- fnmatch is not the same as unix patterns
160
- perhaps add extended globs from rsh/rsync
162
- perhaps a pattern that matches only directories or non-directories
164
* Consider using Python logging library as well as/instead of
167
* Commands should give some progress indication by default.
169
- But quieten this with ``--silent``.
171
* Change to using gettext message localization.
173
* Make a clearer separation between internal and external bzrlib
174
interfaces. Make internal interfaces use protected names. Write at
175
least some documentation for those APIs, probably as docstrings.
177
Consider using ZopeInterface definitions for the external interface;
178
I think these are already used in PyBaz. They allow automatic
179
checking of the interface but may be unfamiliar to general Python
180
developers, so I'm not really keen.
182
* Commands to dump out all command help into a manpage or HTML file or
185
* Handle symlinks in the working directory; at the very least it
186
should be possible for them to be present and ignored/unknown
187
without causing assertion failures.
189
Eventually symlinks should be versioned.
191
* Allow init in a subdirectory to create a nested repository, but only
192
if the subdirectory is not already versioned. Perhaps also require
193
a ``--nested`` to protect against confusion.
197
* More test framework:
199
- Class that describes the state of a working tree so we can just
202
* There are too many methods on Branch() that really manipulate the
203
WorkingTree. They should be moved across.
205
Also there are some methods which are duplicated on Tree and
206
Inventory objects, and it should be made more clear which ones are
207
proxies and which ones behave differently, and how.
209
* Try using XSLT to add some formatting to REST-generated HTML. Or
210
maybe write a small Python program that specifies a header and foot
211
for the pages and calls into the docutils libraries.
213
* --format=xml for log, status and other commands.
215
* Attempting to explicitly add a file that's already added should give
216
a warning; however there should be no warning for directories (since
217
we scan for new children) or files encountered in a directory that's
220
* Better handling of possible collisions on case-losing filesystems;
221
make sure a single file does not get added twice under different
224
* Clean up XML inventory:
226
- Use nesting rather than parent_id pointers.
228
- Hold the ElementTree in memory in the Inventory object and work
229
directly on that, rather than converting into Python objects every
230
time it is read in. Probably still exposoe it through some kind of
231
object interface though, but perhaps that should just be a proxy
234
- Less special cases for the root directory.
236
* Perhaps inventories should remember the revision in which each file
237
was last changed, as well as its current state? This is a bit
238
redundant but might often be interested to know.
240
* stat cache should perhaps only stat files as necessary, rather than
241
doing them all up-front. On the other hand, that disallows the
242
opimization of stating them in inode order.
244
* It'd be nice to pipeline multiple HTTP requests. Often we can
245
predict what will be wanted in future: all revisions, or all texts
246
in a particular revision, etc.
248
urlgrabber's docs say they are working on batched downloads; we
249
could perhaps ride on that or just create a background thread (ew).
251
* Should be a signature at the top of the cache file.
253
* Paranoid mode where we never trust SHA-1 matches.
259
* Generate annotations from current file relative to previous
262
- Is it necessary to store any kind of annotation where data was
265
* Update revfile_ format and make it active:
267
- Texts should be identified by something keyed on the revision, not
268
an individual text-id. This is much more useful for annotate I
269
think; we want to map back to the revision that last changed it.
271
- Access revfile revisions through the Tree/Store classes.
273
- Check them from check commands.
277
.. _revfile: revfile.html
279
* Hooks for pre-commit, post-commit, etc.
281
Consider the security implications; probably should not enable hooks
282
for remotely-fetched branches by default.
284
* Pre-commit check. If this hook is defined, it needs to be handled
285
specially: create a temporary directory containing the tree as it
286
will be after the commit. This means excluding any ignored/unknown
287
files, and respecting selective commits. Run the pre-commit check
288
(e.g. compile and run test suite) in there.
292
* GUI (maybe in Python GTK+?)
294
* C library interface
296
* Expansion of $Id$ keywords within working files. Perhaps do this in
297
exports first as a simpler case because then we don't need to deal
298
with removing the tags on the way back in.
