Highlights
==========
* Documentation is in much better shape. Thanks everybody.
* Two grave bugs in 'git fetch' were caught and fixed. One is "Fix
fetching of tags", the other is "Fix pulling into the same branch.".
* We have archimport (unfortunately undocumented yet), and
cvsimport is being improved.
* Revert, rebase and cherry-pick are done using three-way merge,
not a straight patch application.
* 'git commit' should be a bit easier to use than before in
initial commits and merge commits.
* 'git applymbox' is a bit more accomodating and it should be
easier to handle MIME patches than before.
* As usual, comes with more recent gitk.
Better merge algorithms and the infrastructure are being worked
on by Daniel and Fredrik; they are not in this release yet.
What to expect after 0.99.6
===========================
This is written in a form of to-do list for me, so if I say
"accept patch", it means I do not currently plan to do that
myself. People interested in seeing it materialize please take
a hint. The latest copy of this document is found at
http://kernel.org/git/?p=git/git.git;a=blob;hb=todo;f=TODO
Tool Renames Plan
-----------------
- All non-binary commands will lose -script suffix in
$(bindir). The source to git-foo will be either git-foo.sh
or git-foo.perl in the source tree, and the documentation
will be in Documentation/git-foo.txt.
- The commands whose names have 'cache' to mean 'index file'
will get 'cache' in their names replaced with 'index'. For
git-fsck-cache and git-convert-cache, 'cache' will be
replaced with 'objects'.
- The commit walkers will have 'pull' in their names replaced
with 'fetch'. 'git-ssh-push' will become 'git-ssh-upload'.
- We continue to follow the convention to name the C source
file that contains the main program of 'git-foo' command
'foo.c'. That means we will have 'fsck-objects.c', for
example.
- At this moment, I am not planning to rename the symbols used
in programs, nor any library sources. "cache.h" will stay
"cache.h", so does "read-cache.c". "struct cache_entry" and
"ce_match_stat()" will keep their names. We _might_ want to
rename them in later rounds but not right now.
- In 0.99.7, all renamed commands will have symbolic links in
$(bindir) so that old names continue to work. These backward
compatible symlinks will not be present in documentation,
though. Especially, the main documentation, git(7) will talk
about the new names. Old environment names defined in
gitenv() will also be removed in this release.
Tentatively we aim to do this on Sep 17th.
- In 0.99.8, we do not install these backward compatible
symbolic links in $(bindir) anymore. The Makefile will have
a target to remove old symlinks from $(DESTDIR)$(bindir) you
can run manually to help you clean things up.
The timeframe for this is around Oct 1st, but I could be
talked into delaying the symlink removal if Porcelain people
find this schedule too tight.
Documentation
-------------
* Accept patches from people who actually have done CVS
migration and update the cvs-migration documentation.
Link the documentation from the main git.txt page.
* Accept patches from people who were hit by shiny blue bat to
update the SubmittingPatches [ONGOING].
* Talk about using rsync just once at the beginning when
initializing a remote repository so that local packs do not
need to be expanded. I personally do not think we need tool
support for this (but see below about optimized cloning).
* Maybe update tutorial with a toy project that involves two or
three developers..
* Update tutorial to cover setting up repository hooks to do
common tasks.
* Accept patches to finish missing docs.
Technical (heavier)
-------------------
* Tony Luck reported an unfortunate glitch in the 3-way merge.
Encourage discussions to come up with a not-so-expensive way
to catch the kind of ambiguities that led to his misery.
[Daniel's patch looks quite promising, so is the one from
Fredrik.]
* HPA has two projects, klibc and klibc-kbuild, that have large
set of overlapping files in different paths (i.e. one has many
renames from the other). There currently is no way for git to
help keep these two trees in sync, merging criss-cross between
them. The merge logic should be able to take advantage of
rename/copy detection smarts git-diff-* family has. Linus,
me, and Daniel outlined a smarter merge strategy for this.
Try them out.
* To make it easier to experiment with different merge
strategies, make git-merge driver that will run merge backends
for the best merge [Outlined the idea; just do it].
* We might want to optimize cloning with GIT native transport
not to explode the pack, and store it in objects/pack instead.
We would need a tool to generate an idx file out of a pack
file for this. Also this itself may turn out to be a bad
idea, making the set of packs in repositories everybody has
different from each other.
* Maybe a pack optimizer. I am not convinced that packing all
objects into a single pack and removing all the existing panck
is the right way to go, since that would work against people
who already have those packs.
* Maybe an Emacs VC backend.
Technical (milder)
------------------
* Tool renames [STARTED].
* Have Daniel's read-tree graduate from "pu" after plugging leaks.
* Implement a merge backend using Daniel's read-tree.
* Accept Fredrik merge after renaming it (I want to name the
driver 'git merge'). Suggest where to place *.py stuff --
probably in $(share)/git-core/ and add Makefile entry for
installation.
* Encourage concrete proposals to commit log message templates
we discussed some time ago.
* Bug Martin for archimport script documentation.
* More portability. I dropped a SunOS patch on the floor by
somebody.
* Accept patches to cause "read-tree -u" delete a directory when
it makes it empty.
* Perhaps accept patches to introduce the concept of "patch flow
expressed as ref mappings" Josef has been advocating about.
* Perhaps accept patches to do undo/redo.
* Maybe grok PGP signed text/plain in applymbox as well.
* Perhaps a tool to revert a single file to pre-modification
state? git-cat-file blob `git-ls-files | grep foo` >foo or
git-cat-file blob `git-ls-tree HEAD foo` >foo? What should
the command be called? git-revert is taken so is
git-checkout.
* A tool to detect, show and prune already merged topic
branches.
* Enhance "git repack" to not always use --all; this would be
handy if the repository contains wagging heads like "pu" in
git.git repository.
* Internally split the project into non-doc and doc parts; add
an extra root for the doc part and merge from it; move the
internal doc source to a separate repository, like the +Meta
repository; experiment if this results in a reasonable
workflow, and document it in howto form if it does.
* Option to limit rename detection for more than N paths.
Technical (trivial)
-------------------
* Perhaps "git branch -d" to delete a branch.
* We would want test scripts for the relative directory path
stuff Linus has been working on. So far, the following
commands should be usable with relative directory paths:
update-cache
ls-files
diff-files
diff-cache
diff-tree
rev-list
rev-parse
* In a freashly created empty repository, `git fetch foo:bar`
works OK, but `git checkout bar` afterwards does not (missing
`.git/HEAD`).
