What's cooking in git.git

What's cooking in git.git

[Junio C Hamano]

I have queued the following for the maintenance branches.

For both 1.0.X and 1.1.X series:

 - update-index: work with c-quoted name
 - show-branch: handle [] globs as well.
 - name-rev: do not omit leading components of ref name.

For 1.1.X series only:

 - Add git-describe to .gitignore.
 - describe: do not silently ignore indescribable commits

I plan to do 1.0.10 [*1*] and 1.1.2 sometime this weekend, along
with some other fixes that would appear until then.

On the development front, I have these in the proposed updates
branch:

 - Exec git programs without using PATH (Michal Ostrowski).

   This has been discussed for the last couple of days on the
   list.  I think C side is ready to go in, but I'd like to
   decide what to do on the scripting side before merging it
   into the master branch.

 - Disable USE_SYMLINK_HEAD by default (Pavel Roskin).

   This has been on hold for almost two months -- forever in git
   timescale.

   One offender that could have been broken by this change was
   fixed recently (gitweb), so this can go in anytime now.  Do
   people still care about it?  The argument for the change when
   it was proposed was "then we only have to worry about one
   format of .git/HEAD, not two", and it still is a valid
   argument from Porcelain writers' point of view.  To be
   honest, since I do not do Porcelain, I am neutral about it.

 - convert-packs: futureproofing.
 - Require packfiles to follow the naming convention (preparation).

   These two I have been holding for a while.  I would
   eventually like to force people to rename the packfiles
   created by GIT older than v0.99.9 which has unverifiable
   hexadecimal string in their names and these are the first
   two baby steps toward that goal.  If people object to the
   idea of verifiable packname in general, please raise hand,
   and I may be talked into shelving the whole thing.

 - Documentation: show-branch.
 - show-branch: always include the current branch
 - show-branch: make --topo-order noop and default.
 - show-branch: make the current branch stand out.

   Here are mostly usability updates.

I'll send out some of the above patches to the list separately
for discussion and review.


[Footnote]

*1* 1.0.X series maintenance can largely be ignored by general
public, since I do not see any reason to stick to 1.0.X series.
1.1.X series does not have any backward incompatibility issues
as far as I know.  I am doing 1.0.X series primarily as a
practice for myself, and to experiment with a maintainer
workflow like this:

 - "fixo/1.0" topic branch queues fixes applicable for 1.0
   series *and* *later* maintenance series.

 - "fix" topic branch queues fixes applicable only for the
   current maintenance series.

 - "mainto/1.0" branch is used to cut releases for the 1.0.X
   maintenance series from.  This pulls from "fixo/1.0" topic
   branch.

 - "maint" branch is used to cut releases for the current
   maintenance series from.  This pulls from both "fix" topic
   branch and "mainto/*" topic branches.

With this setup, I can first merge "fixo/1.0" to "mainto/1.0",
and then merge "mainto/1.0" and "fix" branches to "maint", to
come up with something like this:

    $ git show-branch fix fixo/* maint mainto/*
    ! [fix] describe: do not silently ignore indescribable commits
     ! [fixo/1.0] name-rev: do not omit leading components of ref name.
      * [maint] GIT 1.1.2 (not really -- just a demonstration)
       ! [mainto/1.0] GIT 1.0.10 (not really -- just a demonstration)
    ----
      *  [maint] GIT 1.1.2 (not really -- just a demonstration)
    + *  [fix] describe: do not silently ignore indescribable commits
    + *  [fix^] Add git-describe to .gitignore.
      *  [maint^] Merge fixes up to GIT 1.0.10 (not really)

I've done a minor fix in the Makefile (things were installed in
the wrong way around --- $bindir should hold git and gitk and
$gitexecdir should hold the rest), and ran a brief test after
installing things with gitexecdir set to /usr/lib/git-core/x.
gitk needs to be taught to use git --exec-path upfront to set
its own PATH, but other than that, everything looks peachy.

About prepending to/appending to/not touching PATH, my current
thinking is that prepending is the way to go.  The best
rationale so far I have heard against mucking with PATH was
"/home/mo/bin/diff vs /usr/bin/diff" issue, but I do not find
this to be so convincing in practice.  This "use my diff not
system diff" is done most often when system diff is not GNU
enough, but on such a machine git will not be installed under
/usr/bin anyway (after all git prefers GNU diff).

And this becomes truly a non-issue when you point $gitexecdir at
a separate location that holds *only* git stuff.  Everybody will
find the matching version of git that way, and when looking for
"diff", it will be found from one of the directories in the rest
of the PATH, not from $gitexecdir.

So unless there is an objection, this will graduate into the
"master" branch over the weekend.

What happens if gitexecdir != bindir?

As long as the user invokes "git foo" from the command line, not
"git-foo", everything should work fine, and once gitk is
updated, binary distributions could ship git with only git and
gitk in /usr/bin and others in /usr/lib/git-core/tools, or
something like that.

I will _not_ change the default gitexecdir in my Makefile nor
change the spec file, so RPM binary from kernel.org will still
have everything in /usr/bin for now.

Somebody needs to audit how ready popular Porcelains are, for at
least Cogito, stgit, gitweb and qgit and feed patches to
respective authors as necessary.  I haven't looked into any of
them about this issue.  The rules are:

    (1) you can assume "git" is available on PATH;

    (2) you should be safe if you do not use "git-foo" form;

    (3) you can run

        PATH="$(git --exec-path):$PATH"; export PATH

        once at the beginning of your program and use "git-foo"
        form.

Yes, I'd still be pleased to see this. Cogito should be ready for this
for long enough, as far as I'm concerned.

So it turns out that you run "strace -k -o /tmp/tr" and never look
at /tmp/tr; I am guessing that this was a remnant of your debugging
while developing the test, sign of lack of proofreading before
sending the patch out, perhaps?

I didn't carefully read the remainder of the patch, but at the
minimum this needs to be squashed in.  They may be a reroll with
some more tweaks from you after other people comment on it, so I'll
keep this separate and squashable.

Thanks.

I am really looking forward to that, with my Windows performance hat firmly on my head.

The problem fixed by this one has bugged me plenty of times. I often need to edit the TODO e.g. when I managed to get the reordering wrong and want to insert a `pick <commit>` later in the `git-rebase-todo` and then call `git rebase --skip`.

Read: I am very much in favor of fast-tracking this topic.

All tests pass for me locally.  What's broken for you?

What's cooking in git.git

[Junio C Hamano]

This is still a draft but only to show the highlights on new topics.

* bb/remote-get-url (2015-08-05) 1 commit
 - remote: add get-url subcommand

 "git remote" learned "get-url" subcommand to show the URL for a
 given remote name used for fetching and pushing.

 Expecting a reroll.


* dt/untracked-subdir (2015-08-05) 2 commits
 - DONTMERGE: Waiting for an Ack from Duy
 - untracked-cache: fix subdirectory handling
 (this branch uses dt/untracked-sparse.)

 This seems to break some tests.



* cb/open-noatime-clear-errno (2015-08-05) 1 commit
 - git_open_noatime: return with errno=0 on success

 Breaks build; need to tweak.


* jk/guess-repo-name-regression-fix (2015-08-05) 2 commits
 - clone: use computed length in guess_dir_name
 - clone: add tests for output directory
 (this branch is used by ps/guess-repo-name-at-root.)

 "git clone $URL" in recent releases of Git contains a regression in
 the code that invents a new repository name incorrectly based on
 the $URL.  This has been corrected.

 May need some tests from SQUASH??? on ps/guess-repo-name-at-root
 squashed into this, but otherwise looks good.


* ps/guess-repo-name-at-root (2015-08-05) 4 commits
 - SQUASH???
 - clone: abort if no dir name could be guessed
 - clone: do not use port number as dir name
 - clone: do not include authentication data in guessed dir
 (this branch uses jk/guess-repo-name-regression-fix.)

 "git clone $URL", when cloning from a site whose sole purpose is to
 host a single repository (hence, no path after <scheme>://<site>/),
 tried to used the site name as the new repository name, but did
 not remove username or password when <site> part was of the form
 <user>@<pass>:<host>.  The code is taught to redact these.


* jk/notes-merge-config (2015-08-05) 4 commits
 - SQUASH???
 - notes: add notes.merge option to select default strategy
 - notes: add tests for --commit/--abort/--strategy exclusivity
 - notes: document cat_sort_uniq rewriteMode

 "git notes merge" can be told with "--strategy=<how>" option how to
 automatically handle conflicts; this can now be configured by
 setting notes.merge configuration variable.

 The last step to add more specific notes.$ref.merge looked
 questionable.

 Waiting for reroll.


* mk/submodule-gitdir-path (2015-08-05) 2 commits
 - path: implement common_dir handling in git_path_submodule()
 - submodule refactor: use git_path_submodule() in add_submodule_odb()

 The submodule code has been taught to work better with separate
 work trees created via "git worktree add".


* mm/pull-upload-pack (2015-07-30) 1 commit
 - pull.sh: quote $upload_pack when passing it to git-fetch

 "git pull" in recent releases of Git has a regression in the code
 that allows custom path to the --upload-pack=<program>.  This has
 been corrected.

 Will merge to 'maint'.

 This should have already become irrelevant in 'master' with "git
 pull" getting rewritten in C.


* ps/t1509-chroot-test-fixup (2015-08-05) 2 commits
 - tests: fix cleanup after tests in t1509-root-worktree
 - tests: fix broken && chains in t1509-root-worktree

 t1509 test that requires a dedicated VM environment had some
 bitrot, which has been corrected.

 Will merge to 'next'.


* pt/am-builtin-options (2015-08-05) 4 commits
 - am: let --signoff override --no-signoff
 - am: let command-line options override saved options
 - squash! test_terminal: redirect child process' stdin to a pty
 - test_terminal: redirect child process' stdin to a pty
 (this branch uses pt/am-builtin.)

 After "git am --opt1" stops, running "git am --opt2" pays attention
 to "--opt2" only for the patch that caused the original invocation
 to stop.


* sb/remove-get-pathspec (2015-08-03) 1 commit
 - builtin/mv: remove get_pathspec()

 Expecting a reroll ($gmane/275224).


* sb/submodule-helper (2015-08-05) 1 commit
 - submodule: implement `module_list` as a builtin helper

 The beginning of "git submodule" rewritten in C.


* tb/complete-rebase-i-edit-todo (2015-08-05) 1 commit
 - completion: offer '--edit-todo' during interactive rebase

 Comments?


* jk/negative-hiderefs (2015-07-28) 2 commits
 - refs: support negative transfer.hideRefs
 - docs/config.txt: reorder hideRefs config

 Allow negative !ref entry in multi-value transfer.hideRefs
 configuration to say "don't hide this one".

 An update to test coming?

I think the last issue in "consolidated topic listing" format
was a success, so this is in the same format.  In the following
listing, a commit in 'next' has '+' in front, and the ones only
in 'pu' have '-' in front.  The date after each topic name is
the last time the topic was touched.

* jc/diff--cached (Wed Dec 13 01:33:43 2006 -0800) 1 commit
 + Revert "git-diff: Introduce --index and deprecate --cached."

Will merge to 'master' shortly and will be in v1.5.0.

* jc/git-add--interactive (Mon Dec 11 17:09:26 2006 -0800) 2 commits
 - git-add --interactive: hunk splitting
 - git-add --interactive

Undecided.  Either drop it altogether or merge it to 'next'
after adding 'edit' interface to the index contents.

* jn/web (Sun Dec 10 13:25:49 2006 +0100) 5 commits
 + gitweb: SHA-1 in commit log message links to "object" view
 + gitweb: Hyperlink target of symbolic link in "tree" view (if
   possible)
 + gitweb: Add generic git_object subroutine to display object of any
   type
 + gitweb: Show target of symbolic link in "tree" view
 + gitweb: Don't use Content-Encoding: header in git_snapshot

Haven't looked at them fully, but likely to be in v1.5.0.

* jc/blame-boundary (Fri Dec 1 20:45:45 2006 -0800) 1 commit
 + git-blame: show lines attributed to boundary commits differently.

This does not break gitweb nor git-cvsserver because they have
no way to specify boundary commits.  Likely to be in v1.5.0.

Later we can update gitweb to allow specifying the range and
handle 'boundary' annotations in a special way.

* jc/explain (Mon Dec 4 19:35:04 2006 -0800) 1 commit
 - git-explain

We probably should come up with a unified way to allow various
commands that can leave the working tree into special states to
communicate with each other first.  Will NOT be in v1.5.0.

* jc/patch-inline-comments (Fri Dec 8 21:03:52 2006 -0800) 1 commit
 - mailinfo: hack to accept in-line annotations in patches.

Will drop.

* sv/git-svn (Tue Dec 5 16:17:38 2006 +1100) 5 commits
 - git-svn: re-map repository URLs and UUIDs on SVK mirror paths
 - git-svn: collect revision properties when fetching
 - git-svn: collect SVK source URL on mirror paths
 - git-svn: let libsvn_ls_fullurl return properties too
 - git-svn: make test for SVK mirror path import

Sam Villain's SVN fixes are queued in 'pu' but the series hasn't
seen updates after Eric commented on them.  Still on hold.

* jc/3way (Wed Nov 29 18:53:13 2006 -0800) 1 commit
 + git-merge: preserve and merge local changes when doing fast
   forward

This does the magic unconditionally which I am not 100% happy
about, because the resulting mess could be too large to handle.
On the other hand, the user deserves what he gets if he starts a
merge from wildly unclean state, so it may not be too much of an
issue.  Undecided.

 - rev-list --left-right

I think this needs a better UI integration into 'git log' and
friends, not just rev-list.  Currently, I can say:

  $ git rev-list --no-merges --left-right --pretty v1.4.4.2...master

but that still misses --stat and --patch output.  If people find
this useful, maybe we would want to merge it to 'next' after
adding the option to log and friends (or turn it on
automatically when symmetric difference is used).

* js/shallow (Fri Nov 24 16:00:13 2006 +0100) 15 commits
 + fetch-pack: Do not fetch tags for shallow clones.
 + get_shallow_commits: Avoid memory leak if a commit has been
   reached already.
 + git-fetch: Reset shallow_depth before auto-following tags.
 + upload-pack: Check for NOT_SHALLOW flag before sending a shallow
   to the client.
 + fetch-pack: Properly remove the shallow file when it becomes
   empty.
 + shallow clone: unparse and reparse an unshallowed commit
 + Why didn't we mark want_obj as ~UNINTERESTING in the old code?
 + Why does it mean we do not have to register shallow if we have
   one?
 + We should make sure that the protocol is still extensible.
 + add tests for shallow stuff
 + Shallow clone: do not ignore shallowness when following tags
 + allow deepening of a shallow repository
 + allow cloning a repository "shallowly"
 + support fetching into a shallow repository
 + upload-pack: no longer call rev-list

The 'shallow clone'.  Most likely post v1.5.0.

 - gitweb: steal loadavg throttle from kernel.org

If somebody steps up to maintain the gitweb installation at
kernel.org, merging this would make one less thing to customize
there.  Undecided.

* jc/pickaxe (Sun Nov 5 11:52:43 2006 -0800) 1 commit
 - blame: --show-stats for easier optimization work.

This is developer-only; will hold.

* jc/diff (Mon Sep 25 23:03:34 2006 -0700) 1 commit
 - para-walk: walk n trees, index and working tree in parallel

Backburnered and will continue to hold.  I suspect unpack-trees
logic that is used by read-tree would turn out to be too
cumbersome to optimize and at that point this might become
useful.

* jc/diff-apply-patch (Fri Sep 22 16:17:58 2006 -0700) 1 commit
 + git-diff/git-apply: make diff output a bit friendlier to GNU patch
   (part 2)

Will hold until February.
