t/gitweb-lib.sh: Ensure that errors are shown for --debug --immediate
Because '--immediate' stops test suite after first error, therefore in
this mode
test_debug 'cat gitweb.log'
was never ran, thus in effect negating effect of '--debug' option.
This made finidng the cause of errors in gitweb test sute difficult.
Modify the gitweb_run test subroutine to run test_debug itself in the
case of errors (and also remove "test_debug 'cat gitweb.log'" from
gitweb tests).
This makes it possible to run *gitweb tests* with --immediate ---debug
combination of options; also it makes gitweb tests to not output

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:
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.

Even though fill_directory() takes pathspec, the returned set of paths
is not guaranteed to be free of paths outside the pathspec. Perhaps we
would need to change that, but the current API is that the caller needs
to further filter them.
Since bb0a484 (mergetool: Skip autoresolved paths, 2010-08-17),
mergetool uses different ways of figuring out the list of files with
merge conflicts depending on whether rerere is active. If rerere is
active, mergetool will use 'git rerere status' to list the files with
remaining conflicts. However, the output from that command does not
list conflicts of types that rerere does not handle, such as
modify/remove conflicts.
Another problem with solely relying on the output from 'git rerere
status' is that, for new conflicts that are not yet known to rerere,
the output from the command will list the files even after adding them
to the index. This means that if the conflicts in some files have been
resolved and 'git mergetool' is run again, it will ask the user
something like the following for each of those files.
file1: file does not need merging
Continue merging other unresolved paths (y/n) ?
Solve both of these problems by replacing the call to 'git rerere
status' with a call to the new 'git rerere remaining' that was
introduced in the previous commit.

After "rerere" resolves conflicts by reusing old resolution, there would
be three kinds of paths with conflict in the index:
* paths that have been resolved in the working tree by rerere;
* paths that need further work whose resolution could be recorded;
* paths that need resolving that rerere won't help.
When the user wants a list of paths that need hand-resolving, output from
"rerere status" does not help, as it shows only the second category, but
the paths in the third category still needs work (rerere only makes sense
for regular files that have both our side and their side, and does not
help other kinds of conflicts, e.g. "we modified, they deleted").
The new subcommand "rerere remaining" can be used to show both. As
opposed to "rerere status", this subcommand also skips printing paths
that have been added to the index, since these paths are already
resolved and are no longer "remaining".
Initial patch provided by Junio. Refactored and modified to skip
resolved paths by Martin. Commit message mostly by Junio.

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'.

Some HTTP/1.1 servers or proxies don't correctly implement the
100-Continue feature of HTTP/1.1. Its a difficult feature to
implement right, and isn't commonly used by browsers, so many
developers may not even be aware that their server (or proxy)
doesn't honor it.
Within the smart HTTP protocol for Git we only use this newer
"Expect: 100-Continue" feature to probe for missing authentication
before uploading a large payload like a pack file during push.
If authentication is necessary, we expect the server to send the
401 Not Authorized response before the bulk data transfer starts,
thus saving the client bandwidth during the retry.
A different method to probe for working authentication is to send an
empty command list (that is just "0000") to $URL/git-receive-pack.
or $URL/git-upload-pack. All versions of both receive-pack and
upload-pack since the introduction of smart HTTP in Git 1.6.6
cleanly accept just a flush-pkt under --stateless-rpc mode, and
exit with success.
If HTTP level authentication is successful, the backend will return
an empty response, but with HTTP status code 200. This enables
the client to continue with the transfer.

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.

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

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.)

mingw: make failures to unlink or move raise a question
On Windows in case a program is accessing a file unlink or
move operations may fail. To give the user a chance to correct
this we simply wait until the user asks us to retry or fail.
This is useful because of the following use case which seem
to happen rarely but when it does it is a mess:
After making some changes the user realizes that he was on the
incorrect branch. When trying to change the branch some file
is still in use by some other process and git stops in the
middle of changing branches. Now the user has lots of files
with changes mixed with his own. This is especially confusing
on repositories that contain lots of files.
Although the recent implementation of automatic retry makes
this scenario much more unlikely lets provide a fallback as
a last resort.
Thanks to Albert Dvornik for disabling the question if users can't see it.
If the stdout of the command is connected to a terminal but the stderr
has been redirected, the odds are good that the user can't see any
question we print out to stderr. This will result in a "mysterious
hang" while the app is waiting for user input.
It seems better to be conservative, and avoid asking for input
whenever the stderr is not a terminal, just like we do for stdin.

mingw: work around irregular failures of unlink on windows
If a file is opened by another process (e.g. indexing of an IDE) for
reading it is not allowed to be deleted. So in case unlink fails retry
after waiting for some time. This extends the workaround from 6ac6f878.

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.

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.

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.

Make hash-object more robust against malformed objects
Commits, trees and tags have structure. Don't let users feed git
with malformed ones. Sooner or later git will die() when
encountering them.
Note that this patch does not check semantics. A tree that points
to non-existent objects is perfectly OK (and should be so, users
may choose to add commit first, then its associated tree for example).

"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.
