bisect: cleanup whitespace errors in git-bisect.sh.

All leading whitespace is now encoded with tabs.

After this patch, the following is true:

RAW=$(cat git-bisect.sh | md5sum) &&
ROUNDTRIP=$(cat git-bisect.sh | expand -i - | unexpand --first-only - | md5sum) &&
LEADING=$(sed -n "/^ */p" < git-bisect.sh | wc -l) &&

git-check-attr: Normalize pathsMichael Haggerty Thu, 4 Aug 2011 04:47:46 +0000 (06:47 +0200)

git-check-attr: Normalize paths

Normalize the path arguments (relative to the working tree root, if
applicable) before looking up their attributes. This requires passing
the prefix down the call chain.

This fixes two test cases for different reasons:

* "unnormalized paths" is fixed because the .gitattribute-file-seeking
code is not confused into reading the top-level file twice.

* "relative paths" is fixed because the canonical pathnames are passed
to get_check_attr() or get_all_attrs(), allowing them to match the
pathname patterns as expected.

docs: put listed example commands in backticksJeff King Thu, 4 Aug 2011 02:13:29 +0000 (20:13 -0600)

docs: put listed example commands in backticks

Many examples of git command invocation are given in asciidoc listing
blocks, which makes them monospaced and avoids further interpretation of
special characters. Some manpages make a list of examples, like:

git foo::
Run git foo.

git foo -q::
Use the "-q" option.

to quickly show many variants. However, they can sometimes be hard to
read, because they are shown in a proportional-width font (so, for
example, seeing the difference between "-- foo" and "--foo" can be
difficult).

This patch puts all such examples into backticks, which gives the
equivalent formatting to a listing block (i.e., monospaced and without
character interpretation).

As a bonus, this also fixes an example in the git-push manpage, in which
"git push origin :::" was accidentally considered a newly-indented list,
and not a list item with "git push origin :" in it.

One use-case for this function is allow git bisect to be used with
damaged repositories where git checkout would fail because the tree
referenced by the commit is damaged.

It can also be used in other cases where actual checkout of the tree
is not required to progress the bisection.

diff -c/--cc: do not mistake "resolved as deletion" as "use working tree"

The combined diff machinery can be used to compare:

- a merge commit with its parent commits;
- a working-tree file with multiple stages in an unmerged index; or
- a working-tree file with the HEAD and the index.

The internal function combine-diff.c:show_patch_diff() checked if it needs
to read the "result" from the working tree by looking at the object name
of the result --- if it is null_sha1, it read from the working tree.

This mistook a merge that records a deletion as the conflict resolution
as if it is a cue to read from the working tree. Pass this information
explicitly from the caller instead.

commit: allow partial commits with relative paths

In order to do partial commits, git-commit overlays a tree on the
cache and checks pathspecs against the result. Currently, the
overlaying is done using "prefix" which prevents relative pathspecs
with ".." and absolute pathspec from matching when they refer to
files not under "prefix" and absent from the index, but still in
the tree (i.e. files staged for removal).

The point of providing a prefix at all is performance optimization.
If we say there is no common prefix for the files of interest, then
we have to read the entire tree into the index.

But even if we cannot use the working directory as a prefix, we can
still figure out if there is a common prefix for all given paths,
and use that instead. The pathspec_prefix() routine from ls-files.c
does exactly that.

Any use of global variables is removed from pathspec_prefix() so
that it can be called from commit.c.

(1) start_command: There is a mechanism that detects errors during
execvp introduced in 2b541bf8 (start_command: detect execvp
failures early). The child writes one byte to a pipe only if
execvp fails. The parent waits for either EOF, when the
successful execvp automatically closes the pipe (see
FD_CLOEXEC in fcntl(1)), or it reads a single byte, in which
case it knows that the execvp failed. This mechanism is
incompatible with the workaround introduced in 35ce8622
(pager: Work around window resizing bug in 'less'), which
waits for input from the parent before the exec. Since both
the parent and the child are waiting for input from each
other, that would result in a deadlock. In order to avoid
that, the mechanism is disabled by closing the child_notifier
file descriptor.

(2) finish_command: The parent correctly detects the 127 exit
status from the child, but the error output goes nowhere,
since by that time it is already being redirected to the
child.

No simple solution for (1) comes to mind.

Number (2) can be solved by not sending error output to the pager.
Not redirecting error output to the pager can result in the pager
overwriting error output with standard output, however.

Since there is no reliable way to handle error reporting in the
parent, produce the output in the child instead.

t7400: fix bogus test failure with symlinked trash

One of the tests in t7400 fails if the trash directory has a
symlink anywhere in its path. E.g.:

$ mkdir /tmp/git-test
$ mkdir /tmp/git-test/real
$ ln -s real /tmp/git-test/link

$ ./t7400-submodule-basic --root=/tmp/git-test/real
...
# passed all 44 test(s)

$ ./t7400-submodule-basic --root=/tmp/git-test/link
...
not ok - 41 use superproject as upstream when path is relative and no url is set there

The failing test does:

git submodule add ../repo relative &&
...
git submodule sync relative &&
test "$(git config submodule.relative.url)" = "$submodurl/repo"

where $submodurl comes from the $TRASH_DIRECTORY the user
gave us. However, git will resolve symlinks when converting
the relative path into an absolute one, leading them to be
textually different (even though they point to the same
directory).

Fix this by asking pwd to canonicalize the name of the trash
directory for us.

gitweb: Introduce common system-wide settings for convenience

Because of backward compatibility we cannot change gitweb to always
use /etc/gitweb.conf (i.e. even if gitweb_config.perl exists). For
common system-wide settings we therefore need separate configuration
file: /etc/gitweb-common.conf.

Long description:

gitweb currently obtains configuration from the following sources:

1. per-instance configuration file (default: gitweb_conf.perl)
2. system-wide configuration file (default: /etc/gitweb.conf)

If per-instance configuration file exists, then system-wide
configuration is _not used at all_. This is quite untypical and
suprising behavior.

Moreover it is different from way git itself treats /etc/git.conf. It
reads in stuff from /etc/git.conf and then local repos can change or
override things as needed. In fact this is quite beneficial, because
it gives site admins a simple and easy way to give an automatic hint
to a repo about things the admin would like.

On the other hand changing current behavior may lead to the situation,
where something in /etc/gitweb.conf may interfere with unintended
interaction in the local repository. One solution would be to
_require_ to do explicit include; with read_config_file() it is now
easy, as described in gitweb/README (description introduced in this
commit).

But as J.H. noticed we cannot ask people to modify their per-instance
gitweb config file to include system-wide settings, nor we can require
them to do this.

Therefore, as proposed by Junio, for gitweb to have centralized config
elements while retaining backwards compatibility, introduce separate
common system-wide configuration file, by default /etc/gitweb-common.conf

tests: print failed test numbers at the end of the test run

On modern multi-core processors "make test" is often run in multiple jobs.
If one of them fails the test run does stop, but the concurrently running
tests finish their run. It is rather easy to find out which test failed by
doing a "ls -d t/trash*". But that only works when you don't use the "-i"
option to "make test" because you want to get an overview of all failing
tests. In that case all thrash directories are deleted end and the
information which tests failed is lost.

If one or more tests failed, print a list of them before the test summary:

failed test(s): t1000 t6500

fixed 0
success 7638
failed 3
broken 49
total 7723

This makes it possible to just run the test suite with -i and collect all
failed test scripts at the end for further examination.
