This reverts commit 6c723f5e6b.
The additional message may be interesting for git developers,
but not useful for the end users, and clutters the output.
When a patch adds a whitespace followed by end-of-line, the
trailing whitespace error was detected correctly but was not
fixed, due to misconversion in 42ab241 (builtin-apply.c: do not
feed copy_wsfix() leading '+').

Correct fast-export file mode strings to match fast-import standard
Improve look of commit search output ('search' view) by better cutting
of matched string and its context in match info, as suggested by Junio.
For example, if you are looking for "very long search string" in the
following line:
Could somebody test this with very long search string, and see how
you would now see:
...this with <<very long ... string>>, and see...
instead of:
Could som... <<very long search...>>, and see...
(where <<something>> denotes emphasized / colored fragment; matched
fragment to be more exact).
For this feature, support for fourth [optional] parameter to chop_str
subroutine was added. This fourth parameter is used to denote where
to cut string to make it shorter. chop_str can now cut at the
beginning (from the _left_ side of the string), in the middle
(_center_ of the string), or at the end (from the _right_ side of
the string); cutting from right is the default:
chop_str(somestring, len, slop, 'left') -> ' ...string'
chop_str(somestring, len, slop, 'center') -> 'som ... ing'
chop_str(somestring, len, slop, 'right') -> 'somestr... '
If you want to use default slop (default additional length), use undef
as value for third parameter to chop_str.
While at it, return from chop_str early if given string is so short
that chop_str couldn't shorten it. Simplify also regexp used by
chop_str. Make ellipsis (dots) stick to shortened fragment for
cutting at ends, to better see which part got shortened.
Simplify passing all arguments to chop_str in chop_and_escape_str
subroutine. This was needed to pass additional options to chop_str.

Git has difficulties on file systems that do not properly
distinguish case or modify filenames in unexpected ways. The two
major examples are Windows and Mac OS X. Both systems preserve
case of file names but do not distinguish between filenames that
differ only by case. Simple operations such as "git mv" or
"git merge" can fail unexpectedly. In addition, Mac OS X normalizes
unicode, which make git's life even harder.
This commit adds tests that currently fail but should pass if
file system as decribed above are fully supported. The test need
to be run on Windows and Mac X as they already pass on Linux.
Mitch Tishmack is the original author of the tests for unicode
normalization.

Earlier we had a cop-out in the documentation to make the
behaviour "undefined" if configuration had more than one
insteadOf that would match the target URL, like this:
[url "git://git.or.cz/"]
insteadOf = "git.or.cz:" ; (1)
insteadOf = "repo.or.cz:" ; (2)
[url "/local/mirror/"]
insteadOf = "git.or.cz:myrepo" ; (3)
insteadOf = "repo.or.cz:" ; (4)
It would be most natural to take the longest and first match, i.e.
- rewrite "git.or.cz:frotz" to "git://git.or.cz/frotz" by using
(1),
- rewrite "git.or.cz:myrepo/xyzzy" to "/local/mirror/xyzzy" by favoring
(3) over (1), and
- rewrite "repo.or.cz:frotz" to "git://git.or.cz/frotz" by

This allows users with different preferences for access methods to the
same remote repositories to rewrite each other's URLs by pattern
matching across a large set of similiarly set up repositories to each
get the desired access.
For example, if you don't have a kernel.org account, you might want
settings like:
[url "git://git.kernel.org/pub/"]
insteadOf = master.kernel.org:/pub
Then, if you give git a URL like:
master.kernel.org:/pub/scm/linux/kernel/git/linville/wireless-2.6.git
it will act like you gave it:
git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-2.6.git
and you can cut-and-paste pull requests in email without fixing them
by hand, for example.

Most of the time when I am on a detached HEAD and I am not doing
a rebase or bisect operation the working directory is sitting on a
tagged release of the repository. Showing the tag name instead of
the commit SHA-1 is much more descriptive and a much better reminder
of the state of this working directory.
Now that git-describe --exact-match is available as a cheap means
of obtaining the exact annotated tag or nothing at all, we can
favor the annotated tag name over the abbreviated commit SHA-1.

Sometimes scripts want (or need) the annotated tag name that exactly
matches a specific commit, or no tag at all. In such cases it can be
difficult to determine if the output of `git describe $commit` is a
real tag name or a tag+abbreviated commit. A common idiom is to run
git-describe twice:
if test $(git describe $commit) = $(git describe --abbrev=0 $commit)
...
but this is a huge waste of time if the caller is just going to pick a
different method to describe $commit or abort because it is not exactly
an annotated tag.
Setting the maximum number of candidates to 0 allows the caller to ask
for only a tag that directly points at the supplied commit, or to have
git-describe abort if no such item exists.

If we aren't going to use a ref there is no reason for us to open
its object from the object database. This avoids opening any of

By using the peeled ref information inside of the packed-refs file we
can avoid opening tag objects to obtain the commits they reference.
This speeds up git-describe when there are a large number of tags
in the repository as we have less objects to parse before we can
start commit matching.

Currently the only caller of peel_ref is show-ref, which is using
this function to show the peeled tag information if it is available
from an existing packed-refs file. The call happens during the
for_each_ref callback function, so we have the proper struct ref_list
already on the call stack but it is not easily available to return
the peeled information to the caller.
We now save the current struct ref_list item before calling back
into the callback function so that future calls to peel_ref from
within the callback function can quickly access the current ref.
Doing so will save us an lstat() per ref processed as we no longer
have to check the filesystem to see if the ref exists as a loose
file or is packed. This current ref caching also saves a linear
scan of the cached packed refs list.
As a micro-optimization we test the address of the passed ref name
against the current_ref->name before we go into the much more costly
strcmp(). Nearly any caller of peel_ref will be passing us the same
string do_for_each_ref passed them, which is current_ref->name.

So I find it irritating when git thinks for a long time without telling me
what's taking so long. And by "long time" I definitely mean less than two
seconds, which is already way too long for me.
This hits me when doing a large pull and the checkout takes a long time,
or when just switching to another branch that is old and again checkout
takes a while.
Now, git read-tree already had support for the "-v" flag that does nice
updates about what's going on, but it was delayed by two seconds, and if
the thing had already done more than half by then it would be quiet even
after that, so in practice it meant that we migth be quiet for up to four
seconds. Much too long.
So this patch changes the timeout to just one second, which makes it much
more palatable to me.
The other thing this patch does is that "git checkout" now doesn't disable
the "-v" flag when doing its thing, and only disables the output when
given the -q flag. When allowing "checkout -m" to fall back to a 3-way
merge, the users will see the error message from straight "checkout",
so we will tell them that we do fall back to make them look less scary.

Packing objects can be done in parallell nowadays, but it's
only done if the config option pack.threads is set to a value
above 1. Because of that, the code-path used is often not the
most optimal one.
This patch adds a routine to detect the number of online CPU's
at runtime (online_cpus()). When pack.threads (or --threads=) is
given a value of 0, the number of threads is set to the number of
online CPU's. This feature is also documented.
As per Nicolas Pitre's recommendations, the default is still to
run pack-objects single-threaded unless explicitly activated,
either by configuration or by command line parameter.
The routine online_cpus() is a rework of "numcpus.c", written by
one Philip Willoughby <pgw99@doc.ic.ac.uk>. numcpus.c is in the
public domain and can presently be downloaded from

Callers of start_command() can set the members .in and .out of struct
child_process to a value > 0 to specify that this descriptor is used as
the stdin or stdout of the child process.
Previously, if start_command() was successful, this descriptor was closed
upon return. Here we now make sure that the descriptor is also closed in
case of failures. All callers are updated not to close the file descriptor
themselves after start_command() was called.
Note that earlier run_gpg_verify() of git-verify-tag set .out = 1, which
worked because start_command() treated this as a special case, but now
this is incorrect because it closes the descriptor. The intent here is to
inherit stdout to the child, which is achieved by .out = 0.

By setting .in, .out, or .err members of struct child_process to -1, the
callers of start_command() can request that a pipe is allocated that talks
to the child process and one end is returned by replacing -1 with the
file descriptor.
Previously, a flag was set (for .in and .out, but not .err) to signal
finish_command() to close the pipe end that start_command() had handed out,
so it was optional for callers to close the pipe, and many already do so.
Now we make it mandatory to close the pipe.
