Sorry, I wasn't sure whether to remove them or not. I followed the description

Yes. I think the warnings are correct and should be addressed. E.g. Using
mapcar compared to mapc is slower due to the required accumulation of the
results and the additional garbage collection costs. It's not very dramatic
but there is no reason not to fix it imho.

I thought the multi-commit cherry-pick was supposed to take arbitrary
revision arguments, so you can do:
git cherry-pick master..topic
and likewise you can spell it:
git cherry-pick topic ^master
or:
git cherry-pick ^master topic
So the order of arguments isn't relevant in those cases; the graph
ordering is. I agree it would be nice to make:
git cherry-pick commit1 commit3 commit2
work in the order specified, but how does that interact with existing
cases that provide more traditional revision arguments?

I see that git-diff can be used in place of linux diff for totally
untracked file pairs (which is kind of neat, I guess, if you're partial
to git like I am and would probably prefer to use it as your primary
file-system interface if you could). I assume this new syntax implies
manual usage since scripting this input is less straightforward than
iterating thru a single pair via xargs, etc. In that context, I also
see that git-difftool doesn't bring up kdiff3 (or whatever) but just
does a text diff (git 1.7.1) which is mildly disappointing for mere
mortals like myself who prefer to read side-by-side gui diffs over text
diffS. This, of course, is also preference for someone like me who
wouldn't mind prefixing all of my commands with "git " ;-)

I assume this was prompted by warning messages like this one:
In git-blame-cleanup:
git-blame.el:306:6:Warning: `mapcar' called for effect; use `mapc' or `dolist' instead
Looks reasonable to my very much untrained eyes, and it's consistent

Same here (although I've been too lazy to bisect myself).
The following patch makes the situation better, but is not really a fix:
--- a/contrib/completion/git-completion.bash
+++ b/contrib/completion/git-completion.bash
@@ -525,7 +525,7 @@ __gitcomp ()

+ local cur_="$cur" suffix=""
if [ $# -gt 2 ]; then
cur_="$3"
With this, the trailing space isn't added, but e.g. "git checkout
master<TAB>" does not add the trailing space, at all.
The problem is a little bit below:
IFS=$s
COMPREPLY=($(compgen -P "${2-}" -S "$suffix" -W "$1" -- "$cur_"))
The -S "$suffix" adds a space to the completion, but ZSH escapes the
space (which sounds sensible in general, but is not at all what we
expect). My completion-fu isn't good enough to get any further either
unfortunately.

[Beware, I'm mostly clueless about git internals.]
I don't think that any commit reordering, whether it's based on
committer date, topology, or whatever, is acceptable. Commits must be
picked in the exact order they are specified on the command line.
Besides, AFAICT, parse_args() sets opts->revs->no_walk = 1, which will
cause prepare_revision_walk() to return before it would reach the
topo_order condition, so opts->revs->topo_order = 1 wouldn't have any
effect.
Best,
Gábor

The message means: the remote ref 'refs/heads/master' is stored locally
in 'refs/remotes/common/master'.

"git push" is the same as "git push common" ('common' is the current
branch's remote). Since branch.master.push is not defined this then
uses the push.default config option to determine the action. The
default is 'matching', which means that local branch names are matched
against remote branch names. Local branch master matches remote branch
master. Note that this disregards the setting for
branch.master.upstream. If you do not want that you should set
push.default to 'upstream'.
See the examples in git-push(1) for more details.
Andreas.

This is controlled by the 'push.default' variable, the docs for which
are as follows:
push.default::
Defines the action git push should take if no refspec is given
on the command line, no refspec is configured in the remote, and
no refspec is implied by any of the options given on the command
line. Possible values are:
+
* `nothing` - do not push anything.
* `matching` - push all matching branches.
All branches having the same name in both ends are considered to be
matching. This is the default.
* `upstream` - push the current branch to its upstream branch.
* `tracking` - deprecated synonym for `upstream`.
* `current` - push the current branch to a branch of the same name.
The default of 'matching' pushes X to remotename/X, which is what you
are seeing. You can either set it to 'upstream' or specify the
target explicitly, as in
git push common common:master

Hello!
Seems like I found a bug in the clone / push logic. I'm trying to
clone remote branch master into local branch called common and unable
to push back common to master. Git trying to push local master from
different origin to common/master instead.
Here is a simple example:
# mkdir 123
# git init
# > 123
# git add .
# git commit -m "initial"
# git branch
axet-laptop:123 axet$ git branch
* master
# git remote add common https://github.com/axet/common-bin.git
# git fetch common
From https://github.com/axet/common-bin
* [new branch] master -> common/master
?? already strange master (local) to the remote common/master
# axet-laptop:123 axet$ git checkout -b common common/master
Branch common set up to track remote branch master from common.
Switched to a new branch 'common'
# axet-laptop:123 axet$ git branch
* common
master
axet-laptop:123 axet$
# cat .git/config
[...]
[branch "common"]
remote = common
merge = refs/heads/master
?? correct
axet-laptop:123 axet$ git pull
Already up-to-date.
axet-laptop:123 axet$ git push
To https://github.com/axet/common-bin.git
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/axet/common-bin.git'
To prevent you from losing history, non-fast-forward updates were rejected
Merge the remote changes (e.g. 'git pull') before pushing again. See the
'Note about fast-forwards' section of 'git push --help' for details.
axet-laptop:123 axet$
it tries to push local master to remote common/master which is not correct.

Thanks for the very detailed report!
I didn't test nor even compiled anything but maybe this can be fixed
by adding something like:
opts->revs->topo_order = 1;
in parse_args() or in prepare_revs()
I will try to have a look tonight.

* Zsh completion regression
From: Stefan Haller @ 2012-01-12 11:52 UTC (permalink / raw)
To: git; +Cc: SZEDER Gábor
I'm using zsh 4.3.11.
When I type "git log mas<TAB>", it completes to "git log master\ " (a
backslash, a space, and then the cursor).
Bisecting points to "a31e626 completion: optimize refs completion."
Before this commit, I get "git log master" (with no space at the end).
My completion-fu is not strong enough to dig into this myself, but I'll
be happy to help test, or do whatever else helps.

In-Reply-To: <4F0EA23D.3010603@yandex-team.ru>
The word-diff logic accumulates + and - lines until another line type
appears (normally [ @\]), at which point it generates the word diff.
This is usually correct, but it breaks when the preimage does not have
a newline at EOF:
$ printf "%s" "a a a" >a
$ printf "%s\n" "a ab a" >b
$ git diff --no-index --word-diff a b
diff --git 1/a 2/b

the '\' line flushed the buffers, and the - and + lines were never
matched with each other.
A proper fix would defer such markers until the end of the hunk.
However, word-diff is inherently whitespace-ignoring, so as a cheap
fix simply ignore the marker (and hide it from the output).
We use a prefix match for '\ ' to parallel the logic in
apply.c:parse_fragment(). We currently do not localize this string
(just accept other variants of it in git-apply), but this should be
future-proof.

The rule "non-rev stops rev parsing" is fair enough. The error message
is still very misleading, as it lies about RelNotes not being in HEAD^
and gives the impression that it was parsed as a rev (which I guess it
was, but only to show the message).

I buy these, and I understand why they apply to "git diff" and not GNU
diff.

I don't see a use-case where a command produces old1 new1 old2 new2, but
if there is one, then "| xargs -n 2 diff" is the solution. You don't
need your patch.
> - hell, i might even benefit from git copy/modify detection
I don't see how, if you specify explicitely the pairs (old, new). You
may have such benefit if you let the command-line express "here's a
bunch of old files, and a bunch of new ones", but not with your proposed
syntax.

Sorry for distracting you with the performance argument; it was mostly

In that case (and I should have read the original patch), I am
definitely against this change. It turns the default word-diff into
character-diff, which is something entirely different, and frequently
useless precisely for the reason you state:
> (But I cheated. Foo and Bar have no common characters in common; if

Case in point, consider my patch sent out yesterday
http://article.gmane.org/gmane.comp.version-control.git/188391
It consists of a one-hunk doc update. word-diff is not brilliant:
-k::
Usually the program [-'cleans up'-]{+removes email cruft from+} the Subject:
header line to extract the title line for the commit log
[-message,-]
[- among which (1) remove 'Re:' or 're:', (2) leading-]
[- whitespaces, (3) '[' up to ']', typically '[PATCH]', and-]
[- then prepends "[PATCH] ".-]{+message.+} This [-flag forbids-]{+option prevents+} this munging, and is most
useful when used to read back 'git format-patch -k' output.
[snip the rest as it's only {+}]
But character-diff tries too hard to find common subsequences:
$ g show HEAD^^ --word-diff-regex='[^[:space:]]' | xsel
-k::
Usually the program [-'cl-]{+remov+}e[-an-]s {+email cr+}u[-p'-]{+ft from+} the Subject:
header line to extract the title line for the commit log
message[-,-]
[- among which (1) remove 'Re:' or 're:', (2) leading-]
[- w-]{+. T+}hi[-te-]s[-paces, (3) '[' up t-] o[-']', ty-]p[-ically '[PATCH]', and-]t[-he-]{+io+}n pre[-p-]{+v+}en[-ds "[PATCH] ". This flag forbid-]{+t+}s this munging, and is most
useful when used to read back 'git format-patch -k' output.
[snip]
Wouldn't you agree that
w-]{+. T+}hi[-te-]s[-paces, (3) '[' up t-] o[-']', ty-]p[
is just line noise? The colors don't even help as most of it is removed
(red).
Regarding your examples
> [1] http://article.gmane.org/gmane.comp.version-control.git/105896
> [2] http://article.gmane.org/gmane.comp.version-control.git/105237
first please notice that both of them were written before (and actually
discussing) the introduction of the wordRegex feature. At this point,
we were trying to make up our minds w.r.t. how powerful the feature
needs to be. Nowadays (or in fact, starting a few days after those
emails) the user can easily achieve everything discussed here by setting
the wordRegex to taste.
That being said, I can see some arguments for changing the default to
split punctuation into a separate word. That is, whereas the current
default is semantically equivalent to a wordRegex of
[^[:space:]]*
(but has a faster code path) and your proposal is equivalent to
[^[:space:]]|UTF_8_GUARD
I think there is a case to be made for a default of
[^[:space:]]|([[:alnum:]]|UTF_8_GUARD)+
or some such. There's a lot of bikeshedding lurking in the (non)extent
of the [[:alnum:]] here, however.

I find this very, very unintuitive. I tried with GNU diff:
diff 1 2 3 4
and it complained with "diff: extra operand `3'". I find
git diff --no-index file1.old file1.new
git diff --no-index file2.old file2.new
far more intuitive, less error prone (when you start having a
non-trivial list of arguments, it's hard to tell which is the new and

Hello.
I've got a couple of generated files with obfuscated code.
I want to word-diff them just to make sure that everything is right.
The thing is when word-diff gets oneline file without newline at the end
it compares it with regular line by line diff.
Here is an example. Two one line files generated with perl -e "print 'a
'x10" > file
git diff --word-diff=plain file1 file2

git diff --word-diff=plain file1 file2

This allows you to do

It could be seen as an abuse of "git --no-index", but it's very
tempting considering many bells and whistles git's diff machinery

From: Tay Ray Chuan @ 2012-01-12 7:05 UTC (permalink / raw)
To: Git Mailing List; +Cc: Junio C Hamano
By default (ie. when stash show is invoked without any arguments), the
diff stat of the stashed changes is displayed. Let git-diff decide the
default pretty format to use.
This gives git more consistency, as users who have set their
pretty.format config would naturally expect `git-stash show` to display
the diff in the same pretty format as the other diff-producing procelain
like git-log and git-show.

- gitweb: Fix actionless dispatch for non-existent objects
Looked reasonable.
Not urgent.
* nd/index-pack-no-recurse (2012-01-09) 3 commits
- index-pack: eliminate unlimited recursion in get_delta_base()
- index-pack: eliminate recursion in find_unresolved_deltas
- Eliminate recursion in setting/clearing marks in commit list
The first one looked sensible; I am not sure if the second and third ones
take the right approach.
Will defer till the next cycle.

- do_for_each_ref_in_arrays(): new function
- do_for_each_ref_in_array(): new function
- do_for_each_ref(): correctly terminate while processesing extra_refs
The API for extra anchoring points may require rethought first; that would
hopefully make the "ref" part a lot simpler. And that is happening in
another topic (which has graduated to 'master').
Will defer till the next cycle.
* ss/git-svn-prompt-sans-terminal (2012-01-04) 3 commits
- fixup! 15eaaf4
- git-svn, perl/Git.pm: extend Git::prompt helper for querying users
(merged to 'next' on 2012-01-05 at 954f125)
+ perl/Git.pm: "prompt" helper to honor GIT_ASKPASS and SSH_ASKPASS
The bottom one has been replaced with a rewrite based on comments from
Ævar. The second one needs more work, both in perl/Git.pm and prompt.c, to
give precedence to tty over SSH_ASKPASS when terminal is available.
Will defer till the next cycle.

These are a bit scary changes, but I do think they are worth doing.

We want infinite recursion by default, by max_depth default value is
0, which is non-recursive.

I'm bad at naming, any other names are welcome. onelevel_only sounds good.

I thought of that but not sure it's equivalent to max_depth == 1 or
max_depth == 0, so I separated it for safety and clarity. max_depth
feature is driven by git-grep and there were a few interpretations how
it should behave last time, so I'm not sure if its behavior may change
in future.
