-Tool Renames Plan
-=================
-
- - In 0.99.7, all renamed commands 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 will 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.
-
- As a notable exception, 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. Updating to 0.99.8 on one end
- of the connection does not requier the other end to update at
- the same time.
-
- The timeframe for this is around Oct 1st.
-

-What to expect after 0.99.7
-===========================
+What to expect from now on
+==========================
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
-------------
-* 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.
-* Document octopus [Linus prodded me again; DONE].
-* Update tutorial to cover setting up repository hooks to do
- common tasks.
+Design issues
+-------------
-* Accept patches to finish missing docs.
+* 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 talk about "Whoops, it broke. What's
- next?".
+* 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.]
-* Accept patches to make formatted tables in asciidoc to work
- well in both html and man pages (see git-diff(1)).
+* 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.
- [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.
-
* 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>]
* Maybe a pack optimizer.
-* Maybe an Emacs VC backend.
+ 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.
-* 'git split-projects'? This requires updated 'git-rev-list' to
- skip irrelevant commits.
- Message-ID: <Pine.LNX.4.63.0509221617300.23242@iabervon.org>
+* 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)
------------------
-* Use 'git-update-ref' in the scripts.
+* send-pack/receive-pack protocol updates, to allow the receiver
+ to report what it did to the ref update requests.
-* Use symbolic refs in .git/HEAD. Should we do that everywhere
- while honoring the symlinked HEAD in the existing repositories
- for backward compatibility, or just only when 'ln -s' fails?
+* Perhaps a smarter HTTP anonymous download via CGI.
-* Revisit 'git-merge'. It probably was a mistake to "loop to
- choose the best one", since what is best is not ill defined to
- begin with. This would make it a lot straightforward to
- loosen the tree cleanliness requirements to the acceptable
- level [DONE].
+* 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.
-* 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 -- and redone very nicely by
- Sergey].
+* 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.
-* Accept patches for more portability.
+ 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.
- * strcasestr() in mailinfo. We may need compat/strcasestr.c;
- this is bugging OpenBSD folks [DONE, thanks to Linus and
- others].
+ [We should not do this, or do this carefully, if we were to
+ merge the "git-checkout (--|<tree>) <path> work from
+ subdirectory" patch.]
- * Solaris portability [ONGOING, thanks to Patrick Mauritz,
- Peter Eriksen and Sean from sympatico].
+* 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.
-* Accept patches to cause "read-tree -u" delete a directory when
- it makes it empty.
+* 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 introduce the concept of "patch flow
- expressed as ref mappings" Josef has been advocating about.
+* daemon --strict-symlink.
-* Perhaps accept patches to do undo/redo.
+* Perhaps detect cloning request in upload-pack and cache the
+ result for next cloning request until any of our refs change.
* Perhaps accept patch to optionally allow '--fuzz' in
'git-apply'.
to say '\No newline' if both input ends with incomplete
lines.
-* 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.
-
-* 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.
-
-* 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.
+* Maybe grok PGP signed text/plain in applymbox as well.
* 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 [DONE].
-
-* Option to limit rename detection for more than N paths [DONE].
-
-* Option to show only status and name from diff [DONE].
-
-* What to name the 'master' version between 0.99.7 and 0.99.8
- and still not break binary distribution folks? 0.99.7z?
- Pasky gave me a good one: 0.99.7.GIT [DONE]
-
-* Listing more than one head on the Pull: line of .git/remotes/
- allows you to make Octopus -- is it useful? Probabaly not.
- Either adopt "only the first head is used for the merge by
- default if taken from .git/remotes/ file", or "list heads to
- merge on a separate Merge: line" proposal. I already have the
- code to do the former, so...
-
Technical (trivial)
-------------------
-* Usher SSL enhancements to http-fetch from Nick Hengeveld into
- a shape acceptable by everybody.
-
-* Require tk 2.4 in the spec file.
+* Versioning scheme. The next maintenance installment will be
+ 1.0.3 not 1.0.0c. The next feature release would be 1.1.0.
-* show-branch naming heads is buggy [DONE].
-
-* Stop installing the old-name symlinks [DONE].
-
-* 'git merge-projects'?
-
-* 'git clone' does not check things out. Should it?
-
-* '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/).
+* 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:
-
- 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`
+ 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`).
