When your current directory is not at the root of the working tree, and you
use the "-f" option with a relative path, the current code tries to read
from a wrong file, since argv[2] is now beyond the end of the rearranged

This patch replaces the incorrect argv[2] with the variable holding the

Teach "git grep" a new "-q" option to report the presense of a match via
its exit status without showing any output, similar to how "grep -q"
works. Internally "grep" engine already knew this "status-only" mode of
operation because it needed to grep inside log message to filter commits
when called from the "git log" machinery, and this patch only exposes it
to the command line tool.
A somewhat unfair benchmark in the Linux kernel directory shows a dramatic
improvement:
(with patch)
$ time ../git.git/git grep -q linux HEAD ; echo $?
real 0m0.030s

In Internet Explorer 8 (IE8) the 'blame_incremental' view, which uses
JavaScript to generate blame info using AJAX, sometimes hang at the
beginning (at 0%) of blaming, e.g. for larger files with long history
like git's own gitweb/gitweb.perl.
The error shown by JavaScript console is "Unspecified error" at char:2
of the following line in gitweb/gitweb.js:
if (xhr.readyState === 3 && xhr.status !== 200) {
Debugging it using IE8 JScript debuger shown that the error occurs
when trying to access xhr.status (xhr is XMLHttpRequest object).
Watch for xhr object shows 'Unspecified error.' as "value" of
xhr.status, and trying to access xhr.status from console throws error.
This bug is some intermittent bug, depending on XMLHttpRequest timing,
as it doesn't occur in all cases. It is probably caused by the fact
that handleResponse is called from timer (pollTimer), to work around
the fact that some browsers call onreadystatechange handler only once
for each state change, and not like required for 'blame_incremental'
as soon as new data is available from server. It looks like xhr
object is not properly initialized; still it is a bug to throw an
error when accessing xhr.status (and not use 'null' or 'undefined' as
value).
Work around this bug in IE8 by using try-catch block when accessing
xhr.status.

introduced the antecedentless phrase "their versions". Worse, in
passages like the following, 'they' is playing two roles.
| highlighting changes from both the HEAD and their versions.

The user most likely does not care about the exact order of
operations because he cannot see it happening anyway. Instead,
try to explain what it means to merge two commits into a single
tree.
While at it:
- Change the heading to TRUE MERGE. The entire manual page is
about how merges work.
- Document MERGE_HEAD. It is a useful feature, since it makes
the parents of the intended merge commit easier to refer to.
- Do not assume commits named on the 'git merge' command line come
from another repository. For simplicity, the discussion of
conflicts still does assume that there is only one and it is a
branch head.
- Do not start list items with `code`. Otherwise, a toolchain bug
produces a line break in the generated nroff, resulting in odd

Signed-off-by: Thomas Rast <trast@student.ethz.ch>
A merge-based operation in git can fail in two ways: one that
stops before touching anything, or one that goes ahead and
results in conflicts.
As the 'git merge' manual explains:
| A merge is always between the current `HEAD` and one or more
| commits (usually, branch head or tag), and the index file must
| match the tree of `HEAD` commit (i.e. the contents of the last commit)
| when it starts out.
Unfortunately, the placement of this sentence makes it easy to
skip over, and its formulation leaves the important point, that
any other attempted merge will be gracefully aborted, unspoken.
So give this point its own section and expand upon it.
Probably this could be simplified somewhat: after all, a change
registered in the index is just a special kind of local
uncommited change, so the second added paragraph is only a
special case of the first. It seemed more helpful to be explicit
here.

The rule has always been that a cache entry that is ce_uptodate(ce)
means that we already have checked the work tree entity and we know
there is no change in the work tree compared to the index, and nobody
should have to double check. Note that false ce_uptodate(ce) does not
mean it is known to be dirty---it only means we don't know if it is
clean.
There are a few codepaths (refresh-index and preload-index are among
them) that mark a cache entry as up-to-date based solely on the return
value from ie_match_stat(); this function uses lstat() to see if the
work tree entity has been touched, and for a submodule entry, if its
HEAD points at the same commit as the commit recorded in the index of
the superproject (a submodule that is not even cloned is considered
clean).
A submodule is no longer considered unmodified merely because its HEAD
matches the index of the superproject these days, in order to prevent
people from forgetting to commit in the submodule and updating the
superproject index with the new submodule commit, before commiting the
state in the superproject. However, the patch to do so didn't update
the codepath that marks cache entries up-to-date based on the updated
definition and instead worked it around by saying "we don't trust the
return value of ce_uptodate() for submodules."
This makes ce_uptodate() trustworthy again by not marking submodule
entries up-to-date.
The next step _could_ be to introduce a few "in-core" flag bits to
cache_entry structure to record "this entry is _known_ to be dirty",
call is_submodule_modified() from ie_match_stat(), and use these new
bits to avoid running this rather expensive check more than once, but
that can be a separate patch.

There is no point doing self-assignments of these variables. Instead,
just export them to the environment, but do so in a sub-shell, because
VAR1=VAL1 VAR2=VAL2 ... command arg1 arg2...
does not mark the variables exported if command that is run
is a shell function, according to POSIX.1.
The callers of do_with_author do not rely on seeing the effect of any
shell variable assignments that may happen inside what was called through
this shell function (currently "output" is the only one), so running it in
the subshell doesn't have an adverse semantic effect.

Refactor checking for a bare repository into its own proc, that relies
on git rev-parse --is-bare-repository if possible. For older versions of
git we fall back to a logic such that the repository is considered bare
if:
* either the core.bare setting is true
* or the worktree is not set and the directory name ends with .git
The error message for the case of an unhandled bare repository is also
updated to reflect the fact that the problem is not the funny name but
the bareness.
The new refactored proc is also used to disable the menu entry to
explore the working copy, and to skip changing to the worktree before

Don't rely on the git worktree being the updir of the gitdir, since it
might not be. Instead, define (and use) a new _gitworktree global
variable, setting it to $GIT_WORK_TREE if present, falling back to
core.worktree if defined, and finally to whatever we guess the correct
worktree is. Getting core.worktree requires the config from the alleged
git dir _gitdir to be loaded early.
Supporting non-standard worktree locations also breaks the git-gui
assumption (made when calling gitk) that the worktree was the dirname of
$_gitdir and that, by consequence, the git dir could be set to the tail
of $_gitdir once we changed to the worktree root directory. Therefore,
we need to export a GIT_DIR environment variable set to the full,
normalized path of $_gitdir instead. We also skip changing to the worktree
directory if it's empty (i.e. if we're working on a bare repository).
