git/TODO

What to expect after 0.99.5
===========================

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.


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.

* Link howto docs from the git.txt page. [DONE]

* Update the SubmittingPatches document to add MUA specific
  hints on how to disable unwanted MIME and flowed-text by
  collecting past list postings [DONE].

* 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).

* Review the existing docs and see if the repository
  organization needs to be clarified further [DONE].

* Update tutorial to cover shared repository style a bit more
  [DONE].

* Maybe update tutorial with a toy project that involves two or
  three developers..

* Document the hooks [DONE].

* Update tutorial to cover setting up repository hooks to do
  common tasks.

* Get help to properly use asciidoc in tutorial [Heck, ended up
  learning it myself, DONE].

* Maybe justify and demonstrate an Octopus in the tutorial
  [STILL NEEDSWORK].

* Add Octopus to the glossary [Thanks Johannes, DONE].


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.]

* 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 [Discussion
  ongoing].

* 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.

* Maybe an Emacs VC backend.


Technical (milder)
------------------

* When the branch head pointed by $GIT_DIR/HEAD changes while
  the index file and working tree are looking the other way
  (e.g. somebody pushed into your repository, or you ran "git
  fetch" to update the ref your working tree is on), "git
  checkout" without -f gets confused.  Figure out a good way to
  handle this. [DONE]

* We still have the same issue with "git fetch".  Fetching into
  the branch one is on _may_ need to do the same thing as
  fetching into anonymous head and then do the resolve.  At
  least it needs a warning. [DONE]

* "git commit -m" should work for initial commits and perhaps
  merge commits as well.  Warning about merge is still a good
  thing to do, while -m is useful in scripted non-interactive
  use, so we need to be careful. [DONE]

* Encourage concrete proposals to commit log message templates
  we discussed some time ago.

* Test apply.c patches from Robert Fitzsmons and have them
  graduate to "master" branch [IN PROGRESS].

* Test read-tree reorganization patches from Daniel and have
  them graduate to "master" branch [TESTED].

* Bug Ryan and work with him to update send-email easier to use.
  [Ryan's patch pushed into "master".  Will see how well it is
  accepted.]

* Look at portability fixes from Jason Riedy

    http://www.cs.berkeley.edu/~ejr/gits/git.git#portable 

  [Applied.  Burned by one of them and backed out, but otherwise
  looks OK.]

* Accept patches to cause "read-tree -u" delete a directory when
  it makes it empty.

* Perhaps accept patches to introduce the concept of "patch flow
  expressed as ref mappings" Josef has been advocating about.

* Perhaps accept patches to do undo/redo.

* MIMEified applymbox to grok B and Q encodings in headers and
  turn them into UTF-8; unwrap QP; explode multipart. [DONE]

* Maybe grok PGP signed text/plain in applymbox as well.

* 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.

* "git cherry-pick" that applies the patch an existing commit
  introduces in its ancestry chain, possibly using the 3-way
  merge machinery. [DONE]

* Update rebase using the cherry-pick command. [DONE]

* Redo "git revert" using 3-way merge machinery. [DONE]

* A tool to detect, show and prune already merged topic
  branches.

* Set up an automated documentation rebuilding procedure at
  kernel.org, using update hook mechanism. [DONE]

* Describe automated documentation rebuilding in a howto form
  [DONE].

* Enhance "git repack" to not always use --all; this would be
  handy if the repository contains wagging heads like "pu" in
  git.git repository.

* Accept and apply "git repack --all" patch, except the part
  that removes the existing packs. [DONE]

* 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.

* Add names to all nodes in show-branch [DONE].

* Option to limit rename detection for more than N paths.

* Tool renames. [Discussion almost concluded, scheduled to
  happen 0.99.7 with backward compatibility links, removing them
  in 0.99.8.]


Technical (trivial)
-------------------

* Look at and merge Debian fixes from Tommi [Done].

* Perhaps "git branch -d" to delete a branch.

* Remove "git clone-dumb-http" [DONE].

* 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


Initial repository Gotchas
--------------------------

* `git fetch foo:bar` works OK, but `git checkout bar`
  afterwards does not (missing `.git/HEAD`).
  
* `git commit -s` did not add signoff for initial commit [DONE].

* `git status` does not work well when missing `.git/HEAD` [DONE].

* `git log` either; git-log-script uses die which does not exist
  [DONE].
