Johannes Schindelin e6d40d65df diff --check: fix off by one error
When parsing the diff line starting with '@@', the line number of the
'+' file is parsed. For the subsequent line parses, the line number
should therefore be incremented after the parse, not before it.

Junio C Hamano 85023577a8 simplify inclusion of system header files.
This is a mechanical clean-up of the way *.c files include
system header files.

 (1) sources under compat/, platform sha-1 implementations, and
     xdelta code are exempt from the following rules;

 (2) the first #include must be "git-compat-util.h" or one of
     our own header file that includes it first (e.g. config.h,
     builtin.h, pkt-line.h);

 (3) system headers that are included in "git-compat-util.h"
     need not be included in individual C source files.

 (4) "git-compat-util.h" does not have to include subsystem
     specific header files (e.g. expat.h).

Nicolas Pitre ebd124c678 make commit message a little more consistent and conforting
It is nicer to let the user know when a commit succeeded all the time,
not only the first time.  Also the commit sha1 is much more useful than
the tree sha1 in this case.

This patch also introduces a -q switch to supress this message as well
as the summary of created/deleted files.

Shawn O. Pearce 1510fea781 Avoid accessing a slow working copy during diffcore operations.
The Cygwin folks have done a fine job at creating a POSIX layer
on Windows That Just Works(tm).  However it comes with a penalty;
accessing files in the working tree by way of stat/open/mmap can
be slower for diffcore than inflating the data from a blob which
is stored in a packfile.

This performance problem is especially an issue in merge-recursive
when dealing with nearly 7000 added files, as we are loading
each file's content from the working directory to perform rename
detection.  I have literally seen (and sadly watched) paint dry in
less time than it takes for merge-recursive to finish such a merge.
On the other hand this very same merge runs very fast on Solaris.

If Git is compiled with NO_FAST_WORKING_DIRECTORY set then we will
avoid looking at the working directory when the blob in question
is available within a packfile and the caller doesn't need the data
unpacked into a temporary file.

We don't use loose objects as they have the same open/mmap/close
costs as the working directory file access, but have the additional
CPU overhead of needing to inflate the content before use.  So it
is still faster to use the working tree file over the loose object.

If the caller needs the file data unpacked into a temporary file
its likely because they are going to call an external diff program,
passing the file as a parameter.  In this case reusing the working
tree file will be faster as we don't need to inflate the data and
write it out to a temporary file.

The NO_FAST_WORKING_DIRECTORY feature is enabled by default on
Cygwin, as that is the platform which currently appears to benefit
the most from this option.

Andy Parkins a159ca0cb7 Allow subcommand.color and color.subcommand color configuration
While adding colour to the branch command it was pointed out that a
config option like "branch.color" conflicts with the pre-existing
"branch.something" namespace used for specifying default merge urls and
branches.  The suggested solution was to flip the order of the
components to "color.branch", which I did for colourising branch.

This patch does the same thing for
  - git-log (color.diff)
  - git-status (color.status)
  - git-diff (color.diff)
  - pager (color.pager)

I haven't removed the old config options; but they should probably be
deprecated and eventually removed to prevent future namespace
collisions.  I've done this deprecation by changing the documentation
for the config file to match the new names; and adding the "color.XXX"
options to contrib/completion/git-completion.bash.

Unfortunately git-svn reads "diff.color" and "pager.color"; which I
don't like to change unilaterally.

When a file is created in a subdirectory, we used to say just
the directory name only when that directory also was created,
which did not make sense from two reasons.  It is not any more
significant to create a new file in a new directory than to
create a new file in an existing directory, and even if it were,
reportinging the new directory name without saying the actual
filename is not useful.

Johannes Schindelin 3ed74e608a diff --stat: ensure at least one '-' for deletions, and one '+' for additions
The number of '-' and '+' is still linear. The idea is that
scaled-length := floor(a * length + b) with the following constraints: if
length == 1, scaled-length == 1, and the combined length of plusses
and minusses should not be larger than the width by a small margin. Thus,

	a + b == 1

and
	a * max_plusses + b + a * max_minusses + b = width + 1

The solution is

	a * x + b = ((width - 1) * (x - 1) + max_change - 1)
		 / (max_change - 1)

Shawn Pearce e702496e43 Convert memcpy(a,b,20) to hashcpy(a,b).
This abstracts away the size of the hash values when copying them
from memory location to memory location, much as the introduction
of hashcmp abstracted away hash value comparsion.

A few call sites were using char* rather than unsigned char* so
I added the cast rather than open hashcpy to be void*.  This is a
reasonable tradeoff as most call sites already use unsigned char*
and the existing hashcmp is also declared to be unsigned char*.

[jc: Splitted the patch to "master" part, to be followed by a
 patch for merge-recursive.c which is not in "master" yet.

 wrong in the original.

Junio C Hamano 83ad63cfeb diff: do not use configuration magic at the core-level
The Porcelainish has become so much usable as the UI that there
is not much reason people should be using the core programs by
hand anymore.  At this point we are better off making the
behaviour of the core programs predictable by keeping them
unaffected by the configuration variables.  Otherwise they will
become very hard to use as reliable building blocks.

For example, "git-commit -a" internally uses git-diff-files to
figure out the set of paths that need to be updated in the
index, and we should never allow diff.renames that happens to be
in the configuration to interfere (or slow down the process).

The UI level configuration such as showing renamed diff and
coloring are still honored by the Porcelainish ("git log" family
and "git diff"), but not by the core anymore.
