+The GIT To-Do File
+==================
-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

-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.
+Tool Renames Plan
+=================
- - 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 0.99.8, we will still install the backward compatible
+ symbolic links in $(bindir). These will however be removed
+ before 1.0 happens.
- - 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.
+ git-ssh-push and git-ssh-pull pair is not going away within
+ this timeframe, if ever. Each of these old-name commands
+ continues to invoke its old-name counterpart on the other
+ end.
- 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.
+What to expect after 0.99.8
+===========================
- 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.
+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. 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.
+
* 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
* Accept patches to finish missing docs.
+* Accept patches to talk about "Whoops, it broke. What's
+ next?".
+
+* 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.
- [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
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.
+* 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.
+
+* Libification. There are many places "run once" mentality is
+ ingrained in the management of basic data structures, which
+ 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]
+
+* Accept patches to fetch multiple objects by HTTP in parallel.
+ [Preferably before 1.0]
+
+* Plug-in file-level merges [Post 1.0].
+
Technical (milder)
------------------
-* Tool renames [STARTED].
+* Review the Makefile variables and exporting rules for them,
+ while looking at prefix passing by Kai Ruemmler.
-* Have Daniel's read-tree graduate from "pu" after plugging leaks.
+* Review the 'sparce object database' change by Linus and move
+ the first phase of it to the "master" branch.
-* Implement a merge backend using Daniel's read-tree.
+* Decide on mmap(). I am inclined to just stick to mmap
+ replacement by Johannes Schindelin and do nothing else right
+ now.
-* 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.
+* Revisit Santi's patch to move commit temorary files out of the
+ working tree toplevel. More generally, review the use of
+ temporary files again. Assuming $GIT_DIR is writable is
+ more acceptable, but the working tree toplevel may not be in
+ a rare usage pattern.
-* Encourage concrete proposals to commit log message templates
- we discussed some time ago.
+* Perhaps accept more "want"s in upload-pack and do something
+ intelligent about it.
-* Bug Martin for archimport script documentation.
+* Perhaps detect cloning request in upload-pack and cache the
+ result for next cloning request until any of our refs change.
-* More portability. I dropped a SunOS patch on the floor by
- somebody.
+* Perhaps send less "want"s from fetch-pack.
+
+* Encourage concrete proposals to commit log message templates
+ we discussed some time ago.
* 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.
+* Perhaps accept patch to optionally allow '--fuzz' in
+ 'git-apply'.
+
+* Allow 'git apply' to accept GNU diff 2.7 output that forgets
+ to say '\No newline' if both input ends with incomplete
+ lines.
+
+* What to do with TABs and LFs in pathnames without breaking GNU
+ patch?
+
* 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.
+ state? People with BK background know this operation as
+ 'clean'. 'git checkout [-f] ent [path...]' was suggested by
+ Matthias Urlichs which sounds a natural extention to what the
+ command currently does.
* Enhance "git repack" to not always use --all; this would be
handy if the repository contains wagging heads like "pu" in
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.
+ The point is to make it possible to fork that part off to
+ somebody else; then I do not have to maintain Documentation
+ directory myself anymore, just like I simply slurp the latest
+ gitk from Paul and not worry about it ;-).
+
+* 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.
+
+* 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].
+
+* 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 soon enough].
Technical (trivial)
-------------------
-* Perhaps "git branch -d" to delete a branch.
+* short SHA1 naming is not enforcing uniqueness. Should fix [DONE].
+
+* 'git repack' can be DOSed. Should fix [DONE].
+
+* Stop installing the old-name symlinks [POSTPONED, but before 1.0].
+
+* 'git merge-projects'?

+ Message-ID: <7vvf1tps9v.fsf@assigned-by-dhcp.cox.net>
+
+* 'git lost-and-found'? Link dangling commits found by
+ fsck-objects under $GIT_DIR/refs/lost-found/. Then
+ show-branch or gitk can be used to find any lost commit. [A
+ feeler patch sent out. Very underwhelming response X-<.]
+
+ Do not name it /lost+found/; that would probably confuse
+ things that mistake it a mount point (not our code but
+ somebody else's).
+
+* Add simple globbing rules to git-show-branch so that I can
+ say 'git show-branch --heads "ko-*"' (ko-master, ko-pu, and
+ ko-rc are in refs/tags/).
* 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
+ git-update-index
+ git-ls-files
+ git-diff-files
+ git-diff-index
+ git-diff-tree
+ git-rev-list
+ git-rev-parse
* In a freashly created empty repository, `git fetch foo:bar`
works OK, but `git checkout bar` afterwards does not (missing
