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 0.99.9, the backward compatible symbolic links in
+ $(bindir) will be removed.
- - 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.
+ 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.
- 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.

===========================
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
-------------
+* Document the ref naming restrictions [DONE].
+
+* David Ho's report suggests whatchanged documentation should
+ mention -m as "commonly used options". Steal Linus'
+ response [DONE].
+
+* 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
* Maybe update tutorial with a toy project that involves two or
three developers..
-* Document octopus [Linus prodded me again; DONE].
-
* 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?".
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.
+ 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 [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.
+* 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)
------------------
-* 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.
+* Merlyn reports trouble with http fetch [Hopefully solved by
+ Nick's updates].
-* 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].
+* 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.
-* Encourage concrete proposals to commit log message templates
- we discussed some time ago.
+* Perhaps detect cloning request in upload-pack and cache the
+ result for next cloning request until any of our refs change.
-* Accept patches for more portability.
+* Perhaps accept more "want"s in upload-pack and do something
+ intelligent about it [Ongoing, by Johannes].
- * strcasestr() in mailinfo. We may need compat/strcasestr.c;
- this is bugging OpenBSD folks [DONE, thanks to Linus and
- others].
+* Perhaps send less "want"s from fetch-pack [DONE by JS].
- * Solaris portability [ONGOING, thanks to Patrick Mauritz,
- Peter Eriksen and Sean from sympatico].
+* Look at svn importer Smurf has. There is a small cvsimport
+ update in his tree as well [DONE].
-* Accept patches to cause "read-tree -u" delete a directory when
- it makes it empty.
+* 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]
+
+* Quote the URL so that libcurl's metecharacter mechanism would
+ not kick in [DONE].
+
+* Review the Makefile variables and exporting rules for them,
+ while looking at prefix passing by Kai Ruemmler [DONE].
+
+* Review the 'sparse object database' change by Linus and move
+ the first phase of it to the "master" branch [DONE].
+
+* 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.
to say '\No newline' if both input ends with incomplete
lines.
+* What to do with TABs and LFs in pathnames without breaking GNU
+ patch? [DONE -- go with GNU patch extension proposed by Paul].
+
+* Adjust apply.c to proposed GNU patch extension that quotes \n
+ and \t in C style, inside "". [DONE]
+
+* Adjust diff.c to the same. [DONE]
+
* 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.
+ 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
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 [DONE].
+* 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].
-
-* What to name the 'master' version between 0.99.7 and 0.99.8
- and still not break binary distribution folks? 0.99.7z?
+* An mechanism to ignore filesystem mode bits altogether [DONE].
Technical (trivial)
-------------------
-* show-branch naming heads is buggy.
+* Peter Hagervall's sparse fix [DONE].
+
+* Alex Riesen reported that hooks are in effect in tests.
+ Should fix [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].
+
+* Update fetch-pack and clone-pack to ignore funny refs from the
+ other end, while making sure peek-remote does not discard them.
+ [DONE]

-* Stop installing the old-name symlinks.

-* 'git add --recursive' [DONE]
+* Perhaps show ^{commit}, ^{tree} instead of ^{} from ls-remote? [NO]
+
+* Re-adjust maint branch for the above if we did so. [NOT NEEDED]

+* short SHA1 naming is not enforcing uniqueness. Should fix [DONE].
