The GIT To-Do File ================== The latest copy of this document is found at http://kernel.org/git/?p=git/git.git;a=blob;hb=todo;f=TODO 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. Also whatever I marked "Perhaps" do not have to happen if ever -- only if somebody cares enough and submits a clean patch, perhaps ;-). Documentation ------------- * No pending issues at the moment. "Revamp Tutorial" initiative by Bruce Fields ongoing and things are looking better. Design issues ------------- * 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. * "intent to add" index entries. * 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. * Make 'format-patch' take revision limiters similar to rev-list. For example: A C ....---x---o---o---x---o---o / / / ....---x---o---o B we should be able to format commits 'o', without duplicates, by: $ git format-patch ^A ^B C Currently the closest approximation is $ git format-patch A..C B..C which results in the last two commits including C formatted twice. Technical (heavier) ------------------- * 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: ] * 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) ------------------ * "git status -v" to give commit preview. * Subprojects. I think the "bind commit" approach has been outlined at sufficiently detailed level. Maybe find time to actually start prototyping it? <7vacdzkww3.fsf@assigned-by-dhcp.cox.net> * Shallow clones. * Mark entries as "assume unchanged" in the index. A config item '[core] trust_stat = false' would cause to: - "update-index" with or without --add would mark the path valid after registering. Should we make the working tree file read-only at this point? - checkout-index -u would mark the path and makes the working tree file read-only. - read-tree without -u would mark the path invalid. - update-index --refresh should *not* mark up-to-date paths valid. Impacts to various commands: - update-index --refresh would ignore them. - diff-files would say unchanged. - diff-index without --cached acts the same way as diff-index --cached. * Decide what to do about rebase applied to merged head. One extreme is to allow rebase if "rev-list ours..theirs" gives anything. This loosens the current merge-base based approach. The other extreme is to refuse rebase if "rev-list theirs..ours" contains any merge commit, which was discussed on the list. <43CC695E.2020506@codeweavers.com> * 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. Not recording such keeps the history simpler, and the next merge would soon create a true merge commit anyway, but this does not feel quite right. <20060114021800.4688.qmail@web31803.mail.mud.yahoo.com> * Perhaps a smarter HTTP anonymous download via CGI. * 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. * daemon --strict-symlink. * daemon --base-path does not apply automatically to whitelist somehow feels wrong. If somebody cares enough, accept patches. * 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'. 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]. Technical (trivial) ------------------- * git-proxy should be spawned with sh -c 'command' $1 $2. * test scripts for the relative directory path stuff. * In a freshly created empty repository, `git fetch foo:bar` works OK, but `git checkout bar` afterwards does not (missing `.git/HEAD`).
