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 names will not appear in documentation. The main
- documentation, git(7) will talk about the new names but would
- mention their old names as historical notes. Old environment
- names defined in gitenv() will also be removed in this release.
-
- - 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.
-
-
-What to expect after 0.99.7
+ - Immedately after 0.99.9, the backward compatible symbolic
+ links in $(bindir) will be removed [DONE].
+
+ git-ssh-push and git-ssh-pull pair is not going away if ever.
+ Each of these old-name commands continues to invoke its
+ old-name counterpart on the other end.

===========================
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.
+a hint. Also whatever I marked "Perhaps" do not have to happen
+if ever -- only if somebody cares enough and submits a clean
+patch, perhaps ;-).
Documentation
-------------
+* Help Jon Loeliger to find place in the documentation to place
+ his drawing [DONE].
+
* 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.
-
* 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..
+ three developers.
* Update tutorial to cover setting up repository hooks to do
common tasks.
-* Accept patches to finish missing docs.
+* Do we still have missing docs? If so accept patches to finish
+ them.
+
+* Accept patches to talk about "Whoops, it broke. What's
+ next?" [Started].
+
+* Accept patches to make formatted tables in asciidoc to work
+ well in both html and man pages (see git-diff(1)).
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.
- [Deathmatch between Daniel's and Fredrik's ongoing.]
-
-* 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.
-
-* 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.
+* Assess the side effects of "make the rest of the things
+ magically work from any subdirectory" change by Linus. It is
+ a good change in principle and we would like to have that
+ behaviour but some tool implementations I am sure are assuming
+ to never run from anywhere other than the top.
+
+* Ref namespace management. Perhaps use refs/local/ suggestion
+ by Linus.
+
+* Git daemon, when deployed at kernel.org, might turn out to be
+ quite a burden, since it needs to generate customized packs
+ every time a new request comes in. It may be worthwhile to
+ precompute some packs for popular sets of heads downloaders
+ have and serve that, even if that could give more than the
+ client asks for in some cases. We will know about this soon
+ enough [DONE part to allow using precomputed pack, but not
+ dynamic caching part].
* Libification. There are many places "run once" mentality is
ingrained in the management of basic data structures, which
- need to be fixed.
+ need to be fixed. [Matthias Urlichs is already working on
+ this: <pan.2005.10.03.20.48.52.132570@smurf.noris.de>; Post
+ 1.0].
* Maybe a pack optimizer.
+ Given a set of objects and a set of refs (probably a handful
+ branch heads and point release tags), find a set of packs to
+ allow reasonably minimum download for all of these classes of
+ people: (1) somebody cloning the repository from scratch, (2)
+ somebody who tends to follow the master branch head reasonably
+ closely, (3) somebody who tends to follow only the point
+ releases.
+
* Maybe an Emacs VC backend.
+* 'git split-projects'? This requires updated 'git-rev-list' to
+ skip irrelevant commits.
+ Message-ID: <Pine.LNX.4.63.0509221617300.23242@iabervon.org>
+
+* Look at libified GNU diff CVS seems to use, or libxdiff.
+ [Daniel has his own diff tool almost ready to start
+ integrating and testing; Post 1.0]
+
+* Plug-in file-level merges [Post 1.0].
+
Technical (milder)
------------------
-* The recent commit walker safety patch may be too cautious and
- appears to take forever when cloning. This may even be
- infinitely looping in the code lifted from the old rev-list --
- needs to be taken a look at [DONE INITIAL CUT].
+* Binary package split. Plan laid out and discussion mostly
+ done.
-* Encourage concrete proposals to commit log message templates
- we discussed some time ago.
+* User-relative paths by Andreas Ericsson.
-* Accept patches for more portability.
+* Proxing git:// connection by Paul Collins.
- * strcasestr() in mailinfo. We may need compat/strcasestr.c;
- this is bugging OpenBSD folks.
+* Maybe look at Cogito and see if I can help Pasky to adjust to
+ the later core features? Zack Brown's "cg-seek leaving empty
+ directories" problem is a good example of this.
-* Accept patches to cause "read-tree -u" delete a directory when
- it makes it empty.
+* Perhaps detect cloning request in upload-pack and cache the
+ result for next cloning request until any of our refs change.
-* Perhaps accept patches to introduce the concept of "patch flow
- expressed as ref mappings" Josef has been advocating about.
+* Encourage concrete proposals to commit log message templates
+ we discussed some time ago.
* 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.
-
* 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.
-
* Make rebase restartable; instead of skipping what cannot be
automatically forward ported, leave the conflicts in the work
tree, have the user resolve it, and then restart from where it
- left off.
+ left off [mechanism mostly done].
* Output full path in the "git-rev-list --objects" output, not
just the basename, and see the improved clustering results in
better packing [Tried, but did not work out well].
-* Remove obsolete commands [READY].
+* Updated git-changes-script Jeff Garzik needs [Inquiry for
+ external spec sent out with a quick hack. Will know if that
+ is what he needs hopefully soon].
-* Option to limit rename detection for more than N paths [READY].
-
-* Option to show only status and name from diff [READY].
+* Make sure we do reasonable thing on binary files even in
+ cherry-pick and rebase.
Technical (trivial)
-------------------
-* 'git add --recursive'?
+* Stop installing the old-name symlinks [DONE].
* 'git merge-projects'?
