98885c2914 gitweb/gitweb.perl: don't call S_ISREG() with undef
Change S_ISREG($to_mode_oct) to S_ISREG($from_mode_oct) in the branch
that handles from modes, not to modes. This logic appears to have been
caused by copy/paste programming by Jakub Narebski in e8e41a93. It
would be better to rewrite this code not to be duplicated, but I
haven't done so.

This issue caused a failing test on perl 5.13.9, which has a warning
that turned this up:

     gitweb.perl: Use of uninitialized value in subroutine entry at /home/avar/g/git/t/../gitweb/gitweb.perl line 4415.

Which caused the Git test suite to fail on this test:

    ./t9500-gitweb-standalone-no-errors.sh             (Wstat: 256 Tests: 90 Failed: 84)
      Failed tests:  1-8, 10-36, 38-45, 47-48, 50-88

0f54b7d09a gitweb/gitweb.perl: remove use of qw(...) as parentheses
Using the qw(...) construct as implicit parentheses was deprecated in
perl 5.13.5. Change the relevant code in gitweb to not use the
deprecated construct. The offending code was introduced in 3562198b by
Jakub Narebski.

The issue is that perl will now warn about this:

    $ perl -wE 'for my $i qw(a b) { say $i }'
    Use of qw(...) as parentheses is deprecated at -e line 1.
    a
    b

This caused gitweb.perl to warn on perl 5.13.5 and above, and these
tests to fail on those perl versions:

    ./t9501-gitweb-standalone-http-status.sh           (Wstat: 256 Tests: 11 Failed: 10)

a902618792 clone: die when trying to clone missing local path
Since 86ac751 (Allow cloning an empty repository,
2009-01-23), doing:

  git clone does-not-exist

has created does-not-exist as an empty repository. This was
an unintentional side effect of 86ac751. Even weirder,
doing:

  git clone does-not-exist new-dir

_does_ fail, making this "feature" (if you want to consider
it such) broken. Let's detect this situation and explicitly
die. It's almost certainly not what the user intended.

This patch also adds two tests. One for the missing path
case, and one to confirm that a similar case, cloning a
non-repository directory, fails.

339e5638b0 tests: skip terminal output tests on OS X
On Mac OS X 10.5.0, test_terminal gets stuck reading from the pty
master every once in a while.  To reproduce the problem:

 perl -MIO::Pty -MFile::Copy -e '
	for (my $i = 0;; $i++) {
		my $master = new IO::Pty;
		my $slave = $master->slave;
		if (fork == 0) {
			close $master or die "close: $!";
			open STDOUT, ">&", $slave or die "dup2: $!";
			close $slave or die "close: $!";
			exec("echo", "hi", $i) or die "exec: $!";
		}
		close $slave or die "close: $!";
		copy($master, \*STDOUT) or die "copy: $!";
		close $master or die "close: $!";
		wait;
	}
 '

It blocks after 7000 iterations or so in sysread().  The relevant
sysread() call is the second call by the parent, which presumably
executes before the child dies but after the parent has read all
output from there.

Since this is an intermitent problem, the quick check of terminal
support in lib-terminal doesn't catch it.  Skip these tests on the Mac
for now.

53c403116a push.default: Rename 'tracking' to 'upstream'
Users are sometimes confused with two different types of "tracking" behavior
in Git: "remote-tracking" branches (e.g. refs/remotes/*/*) versus the
merge/rebase relationship between a local branch and its @{upstream}
(controlled by branch.foo.remote and branch.foo.merge config settings).

When the push.default is set to 'tracking', it specifies that a branch should
be pushed to its @{upstream} branch. In other words, setting push.default to
'tracking' applies only to the latter of the above two types of "tracking"
behavior.

In order to make this more understandable to the user, we rename the
push.default == 'tracking' option to push.default == 'upstream'.

push.default == 'tracking' is left as a deprecated synonym for 'upstream'.

48d9e6ae4b perl: command_bidi_pipe() method should set-up git environmens
When command_input_pipe and command_output_pipe are used as a
method of a Git::repository instance, they eventually call into
_cmd_exec method that sets up the execution environment such as
GIT_DIR, GIT_WORK_TREE environment variables and the current
working directory in the child process that interacts with the
repository.

command_bidi_pipe however didn't expect to be called as such, and
lacked all these set-up.  Because of this, a program that did this
did not work as expected:

    my $repo = Git->repository(Directory => '/some/where/else');
    my ($pid, $in, $out, $ctx) =
    $repo->command_bidi_pipe(qw(hash-object -w --stdin-paths));

This patch refactors the _cmd_exec into _setup_git_cmd_env that
sets up the execution environment, and makes _cmd_exec and
command_bidi_pipe to use it.

Note that unlike _cmd_exec that execv's a git command as an
external process, command_bidi_pipe is called from the main line
of control, and the execution environment needs to be restored
after open2() does its magic.

1e58dba142 configure: use AC_LANG_PROGRAM consistently
Avoid warnings from Autoconf 2.68 about missing use of AC_LANG_PROGRAM
and friends.

Quoting autoconf-2.68/NEWS:

  ** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and
     AC_RUN_IFELSE now warn if the first argument failed to use
     AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file
     contents.  A new macro AC_LANG_DEFINES_PROVIDED exists if you have
     a compelling reason why you cannot use AC_LANG_SOURCE but must
     avoid the warning.

The underlying reason for that change is that AC_LANG_{SOURCE,PROGRAM}
take care to supply the previously computed set of #defines (and
include standard headers if so desired) for preprocessed languages
like C and C++.

In some cases, AC_LANG_PROGRAM is already used but not sufficiently
m4-quoted, so we just need to add another set of [quotes] to prevent
the autoconf warning from being triggered bogusly.  Quoting all
arguments (except when calling special macros that need to be expanded
before recursion) is better style, anyway.  These and more rules are
described in detail in 'info Autoconf "Programming in M4"'.

No change in the resulting config.mak.autogen after running
./configure intended.

It is not immediately obvious that the util field may

since the string_list_insert* functions _do_ explicitly zero
the util pointer.

This does not appear to be a bug in any current git code, as
all callers either fill in the util field immediately or
never use it. However, it is worth it to be less surprising
to new users of the string-list API who may expect it to be

definition of EMPTY_TREE_SHA1_BIN to produce a value of more

Define such a macro, expanding roughly to ((a) < UINT_MAX - (b)).
Because the expansion uses each argument only once outside of sizeof()

547e8b9205 fast-import: introduce "feature notes" command
Here is a 'feature' command for streams to use to require support for
the notemodify (N) command.

When the 'feature' facility was introduced (v1.7.0-rc0~95^2~4,
2009-12-04), the notes import feature was old news (v1.6.6-rc0~21^2~8,
2009-10-09) and it was not obvious it deserved to be a named feature.
But now that is clear, since all major non-git fast-import backends
lack support for it.

Details: on git version with this patch applied, any "feature notes"
command in the features/options section at the beginning of a stream
will be treated as a no-op.  On fast-import implementations without
the feature (and older git versions), the command instead errors out
with a message like

	This version of fast-import does not support feature notes.

So by declaring use of notes at the beginning of a stream, frontends
can avoid wasting time and other resources when the backend does not
support notes.  (This would be especially important for backends that
do not support rewinding history after a botched import.)

68595cd442 fast-import: clarify documentation of "feature" command
The "feature" command allows streams to specify options for the import
that must not be ignored.  Logically, they are part of the stream,
even though technically most supported features are synonyms to
command-line options.

Make this more obvious by being more explicit about how the analogy
between most "feature" commands and command-line options works.  Treat
the feature (import-marks) that does not fit this analogy separately.

7811d9600f pull: Document the "--[no-]recurse-submodules" options
In commits be254a0ea9 and 7dce19d374 the handling of the new fetch options
"--[no-]recurse-submodules" had been added to git-pull.sh. But they were
not documented as the pull options they now are, so let's fix that.

cf548cacdd quote.h: simplify the inclusion
Attempting to include quote.h without first including strbuf.h results
in warnings:

 ./quote.h:33:33: warning: ‘struct strbuf’ declared inside parameter list
 ./quote.h:33:33: warning: its scope is only this definition or declaration, which is probably not what you want
 ./quote.h:34:34: warning: ‘struct strbuf’ declared inside parameter list
 ...

Add a toplevel declaration for struct strbuf to avoid this.

While at it, stop including system headers from quote.h.  git source
files already need to include git-compat-util.h sooner to ensure the
appropriate feature test macros are defined.

c4d9986f5f sha1_object_info: examine cached_object store too
Cached object store was added in d66b37b (Add pretend_sha1_file()
interface. - 2007-02-04) as a way to temporarily inject some objects
to object store.

But only read_sha1_file() knows about this store. While it will return
an object from this store, sha1_object_info() will happily say
"object not found".

Teach sha1_object_info() about the cached store for consistency.

a2b7a3b3a9 diff: support --cached on unborn branches
"git diff --cached" (without revision) used to mean "git diff --cached
HEAD" (i.e. the user was too lazy to type HEAD). This "correctly"
failed when there was no commit yet. But was that correctness useful?

This patch changes the definition of what particular command means.
It is a request to show what _would_ be committed without further "git
add". The internal implementation is the same "git diff --cached HEAD"
when HEAD exists, but when there is no commit yet, it compares the index
with an empty tree object to achieve the desired result.
