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 ;-). - - 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'. +Documentation +------------- - - 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. +* No pending issues at the moment. "Revamp Tutorial" initiative + by Bruce Fields ongoing and things are looking better. - - 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 0.99.7, 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. +Design issues +------------- - Tentatively we aim to do this on Sep 17th. +* Rehash "git commit" with various parameters to be more + intuitive without breaking traditinal users too much. We need + to phase this in, especially if we are going to change "git + commit" to imply the current "git commit -a" behaviour. - - 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. +* "intent to add" index entries. - 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. +* 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. +* Doing a merge in a separate directory. -Documentation -------------- +* Make 'format-patch' take revision limiters similar to + rev-list.

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 [Illustration of concept patch sent out, - untested yet]. - -* 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.

[Matthias Urlichs is already working on + this: ] * 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.

What should - the command be called? git-revert is taken so is - git-checkout. +* Decide what the right thing to do upon an empty merge commit, + when both branches happen to have obtained the same set of + changes through different history.

If somebody cares enough, accept + patches. -* Option to limit rename detection for more than N paths. +* Perhaps detect cloning request in upload-pack and cache the + result for next cloning request until any of our refs change. -* 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. +* Perhaps accept patch to optionally allow '--fuzz' in + 'git-apply'. am/applymbox is _not_ the place to do it. + +* Allow 'git apply' to accept GNU diff 2.7 output that forgets + to say '\No newline' if both input ends with incomplete + lines. + +* Perhaps deal with "Files differ" (binary diff) in non C + locales. + +* 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].

So far, the following - commands should be usable with relative directory paths: +* git-proxy should be spawned with sh -c 'command' $1 $2. - git-update-index - git-ls-files - git-diff-files - git-diff-index - git-diff-tree - git-rev-list - git-rev-parse +* test scripts for the relative directory path stuff. -* In a freashly created empty repository, `git fetch foo:bar` +* In a freshly created empty repository, `git fetch foo:bar` works OK, but `git checkout bar` afterwards does not (missing `.git/HEAD`).
