-What to expect after 0.99.6
-===========================
+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.
+Tool Renames Plan
+=================
- - 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'.
+ - In 0.99.8, we still install the backward compatible symbolic
+ links in $(bindir). These will however be removed before 1.0
+ happens.
- - The commit walkers will have 'pull' in their names replaced
- with 'fetch'. 'git-ssh-push' will become 'git-ssh-upload'.
+ 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.
- - 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.
+What to expect after 0.99.8
+===========================
- - 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.
+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 ;-).
- 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.
+Documentation
+-------------
- 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.
+* Document the ref naming restrictions [DONE].
+* David Ho's report suggests whatchanged documentation should
+ mention -m as "commonly used options". Steal Linus'
+ response [DONE].
-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.
-
* 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
* 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?".
+
+* 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.
-
-* To make it easier to experiment with different merge
- strategies, make git-merge driver that will run merge backends
- for the best merge [DONE].
-
-* Sort out the mess objects/info/alternates introduces on the
- client end. Both rsync and commit walkers are broken.
- * describe current situation [DONE]
- * http [Daniel started]
- * rsync
-
* 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.
+ different from each other. [DONE; git-index-pack by Sergey,
+ tweaking clone by me]
+
+* 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.
+ [DONE]
+
+* Plug-in file-level merges [Post 1.0].
+
+* Per-repository configuration mechanism [DONE by Linus].
+
Technical (milder)
------------------
-* Define semantics for relative pathnames in objects/info/alternates.
- Either relative to 'objects', or relative to the top of project tree
- ;the latter is consistent with GIT_ALTERNATE_OBJECT_DIRECTORIES.
- Perhaps would end up doing the former because we would want to be
- consistent between a naked repository and a repository with working
- tree [DONE].
+* Merlyn reports trouble with http fetch.
-* Tool renames. Give fixup patch for at least Cogito and StGIT
- [DONE].
+* 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.
-* Massage ssh-fetch and ssh-upload to be more backward
- compatible.
+* Perhaps detect cloning request in upload-pack and cache the
+ result for next cloning request until any of our refs change.
-* Have Daniel's read-tree graduate from "pu" after plugging
- leaks [DONE].
+* Perhaps accept more "want"s in upload-pack and do something
+ intelligent about it.
-* Implement a merge backend using Daniel's read-tree [DONE].
+* Perhaps send less "want"s from fetch-pack.
-* Rename 'git-merge-resolve' to 'git-merge-stupid' and
- 'git-merge-multibase' to 'git-merge-resolve'; the former is
- for historical curiosity and comparison purposes only and not
- to be used in real applications so remove it from the default
- strategies list [DONE].
+* Look at svn importer Smurf has. There is a small cvsimport
+ update in his tree as well [DONE].
-* 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 [DONE].
+* Decide the notation of "peeling the onion" operator, and
+ implement it in sha1_name.c. Perhaps postfix "^{}" to mean
+ "peel and expect anything", "^{blob}" to mean "peel and barf
+ unless blob". The current "^0" becomes shorthand for
+ "^{commit}". [DONE]
-* Encourage concrete proposals to commit log message templates
- we discussed some time ago.
+* Quote the URL so that libcurl's metecharacter mechanism would
+ not kick in [DONE].
-* Bug Martin for archimport script documentation [DONE].
+* Review the Makefile variables and exporting rules for them,
+ while looking at prefix passing by Kai Ruemmler [DONE].
-* More portability [IN PROGRESS].
+* Review the 'sparse object database' change by Linus and move
+ the first phase of it to the "master" branch [DONE].
-* Accept patches to cause "read-tree -u" delete a directory when
- it makes it empty.
+* Decide on mmap(). I am inclined to just stick to mmap
+ replacement by Johannes Schindelin and do nothing else right
+ now, except perhaps drop the writing-back support [DONE].
-* Perhaps accept patches to introduce the concept of "patch flow
- expressed as ref mappings" Josef has been advocating about.
+* Revisit Santi's patch to move commit temorary files out of the
+ working tree toplevel [DONE].
+
+* More generally, review the use of temporary files again.
+ Assuming writable $GIT_DIR 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.
+
+* Accept patches to cause "read-tree -u" delete a directory when
+ it makes it empty [DONE].
* Perhaps accept patches to do undo/redo.
* Perhaps accept patch to optionally allow '--fuzz' in
'git-apply'.
-* Maybe grok PGP signed text/plain in applymbox as well.
+* Allow 'git apply' to accept GNU diff 2.7 output that forgets
+ to say '\No newline' if both input ends with incomplete
+ lines.
-* 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.
+* What to do with TABs and LFs in pathnames without breaking GNU
+ patch? [DONE -- go with GNU patch extension proposed by Paul].
-* A tool to detect, show and prune already merged topic
- branches [DONE; 'branch -d' to prune; users can do gitk for
- deciding].
+* Adjust apply.c to proposed GNU patch extension that quotes \n
+ and \t in C style, inside "". [DONE]
-* "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.
+* Adjust diff.c to the same. [DONE]
- Do not name it /lost+found/; that would probably confuse
- things that mistake it a mount point (not our code but
- somebody else's).
+* Maybe grok PGP signed text/plain in applymbox as well.
+
+* Perhaps a tool to revert a single file to pre-modification
+ 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 [DONE with a prodding by Linus].
* 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.
-
-* diffcore-rename leak reintroduced because the 'fix' was
- broken [DONE].
-
-* Marking copy seems to be broken when A,B => B,C rename
- happens; we incorrectly say B stays, which makes the new B
- copy of old A, not rename [DONE].
+ 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.
+ 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].
-* Allow 'git apply' to accept GNU diff 2.7 output that forgets
- to say '\No newline' if both input ends with incomplete
- lines.
+* 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].
+
+* An mechanism to ignore filesystem mode bits altogether [DONE].
Technical (trivial)
-------------------
-* Add simple globbing rules for git-show-branch so that I can
- say 'git show-branch --heads "ko-*"' (ko-master, ko-pu, and
- ko-rc are in refs/tags/).
+* Peter Hagervall's sparse fix [DONE].
-* Deal with CDPATH [DONE].
+* Alex Riesen reported that hooks are in effect in tests.
+ Should fix [DONE].
-* Teach 'git format-patch' about 'git cherry' [DONE].
+* Disallow [\001-\040\177] byte values from ref names. Also we
+ need to disallow ':' (used in refspec), '^' and '~' (postfix
+ "peel the onion" operators), and '..' ("ref1..ref2" notation
+ becomes ambiguous otherwise) [DONE].
-* Make 'git bisect' easier to use by logging the earlier
- good/bad choices and make it replayable [DONE].
+* Update fetch-pack and clone-pack to ignore funny refs from the
+ other end, while making sure peek-remote does not discard them.
+ [DONE]
-* Perhaps "git branch -d" to delete a branch. We probably need
- some way to say "delete this branch because everything in this
- should be merged in the master branch" and refuse the removal
- if it is not true [DONE].
+* Update upload-pack to send tag^{}. This would hopefully help
+ Pasky's automated tag tracking, and also Martin's findtags.
+ [DONE]
+
+* Adjust update-index to quoted --index-info [DONE].
+
+* Prepare apply.c changes for maint branch (0.99.8e) [READY].
+
+* Perhaps show ^{commit}, ^{tree} instead of ^{} from ls-remote?
+
+* Re-adjust maint branch for the above if we did so.
+
+* 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'?
