+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.
- - 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 from now on
+==========================
- - 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.
+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

+patch, perhaps ;-).
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..
+ three developers.
+
+
+Design issues
+-------------
-* Update tutorial to cover setting up repository hooks to do
- common tasks.
+* Plug-in file-level merges. On the other hand, we may not even
+ need this; just tell people to run "xxdiff -U" on the working
+ tree files.
-* Accept patches to finish missing docs.
+* Ref namespace management. Perhaps use refs/local/ suggestion
+ by Linus. [Does not seem to be high on people's priority list,
+ and not interested myself. People can resurrect this
+ discussion if they want.]
+
+* Perhaps "everything in config file"? Especially remotes/
+ shortcuts. I am modestly negative about this.
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.
+* 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>]
+
+* 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.
+
+ This needs a matching smart on the dumb protocol downloader.
* Maybe an Emacs VC backend.
+* Look at libified GNU diff CVS seems to use, or libxdiff.
+ [Daniel has his own diff tool almost ready to start
+ integrating and testing]
+
Technical (milder)
------------------
-* Tool renames [STARTED].
+* send-pack/receive-pack protocol updates, to allow the receiver
+ to report what it did to the ref update requests.
-* Have Daniel's read-tree graduate from "pu" after plugging leaks.
+* Perhaps a smarter HTTP anonymous download via CGI.
-* Implement a merge backend using Daniel's read-tree.
+* Prepare to enable "always use symbolic refs for HEAD" patch.
+ We need a timeline to force Porcelains to get ready. Last
+ time I looked at them I got an impression that gitweb was not
+ ready.
-* 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.
+* Forbid/ignore pack names that do not conform to the convention
+ sha1_pack_name() assumes and reject in check_packed_git_idx()
+ [In pu]
-* Encourage concrete proposals to commit log message templates
- we discussed some time ago.
+* strip leading directory from ls-tree output, to match ls-files
+ output.
-* Bug Martin for archimport script documentation.
+ I am of two minds about this one. diff output must always be
+ -p1 format no matter where the command was started, and
+ ls-tree might be easier to use if it matched diff, not
+ ls-files.
-* More portability. I dropped a SunOS patch on the floor by
- somebody.
+ [We should not do this, or do this carefully, if we were to
+ merge the "git-checkout (--|<tree>) <path> work from
+ subdirectory" patch.]
-* Accept patches to cause "read-tree -u" delete a directory when
- it makes it empty.
+* Any Porcelain-ish we forgot or punted to make usable from
+ subdirectory? I think the last pass caught everything and
+ what are remaining are whole-tree or whole repository
+ operations.
-* Perhaps accept patches to introduce the concept of "patch flow
- expressed as ref mappings" Josef has been advocating about.
+* diff stopping at the first output; qgit wants to know if this
+ tree has any A or D from the other tree and nothing else.
+ Would help internal tree-diff in rev-list as well.
-* Perhaps accept patches to do undo/redo.
+* daemon --strict-symlink.
-* Maybe grok PGP signed text/plain in applymbox as well.
+* Perhaps detect cloning request in upload-pack and cache the
+ result for next cloning request until any of our refs change.
-* 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.
+* Perhaps accept patch to optionally allow '--fuzz' in
+ 'git-apply'.
-* A tool to detect, show and prune already merged topic
- branches.
+* Allow 'git apply' to accept GNU diff 2.7 output that forgets
+ to say '\No newline' if both input ends with incomplete
+ lines.
-* Enhance "git repack" to not always use --all; this would be
- handy if the repository contains wagging heads like "pu" in
- git.git repository.
+* Perhaps deal with "Files differ" (binary diff) in non C
+ locales.
-* 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.
+* Maybe grok PGP signed text/plain in applymbox as well.
-* Option to limit rename detection for more than N paths.
+* 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].
Technical (trivial)
-------------------
-* Perhaps "git branch -d" to delete a branch.
+* Versioning scheme. The next maintenance installment will be
+ 1.0.3 not 1.0.0c. The next feature release would be 1.1.0.
+
+* Either drop supporting Debian myself or coerce patches out of
+ the official maintainer.
* 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`
+ stuff Linus has been working on. Most of the C-level
+ commands should be usable with relative directory paths.
+
+* In a freshly created empty repository, `git fetch foo:bar`
works OK, but `git checkout bar` afterwards does not (missing
`.git/HEAD`).
