The new option behaves just like --verify, but outputs an

The minimum length of abbreviated object name was hardcoded in
different places to be 4, risking inconsistencies in the future.
Also there were three different "default abbreviation
precision".  Use two C preprocessor symbols to clean up this
mess.

The files with conflicts need to be hand resolved, and it is a
good discipline for the committer to explain which branch was
taken and why.  Pre-fill the merge message template with the

If the index records an insanely long symbolic link, copying
into the temporary would overflow the buffer (noticed by Mark
Wooding).

Because read_sha1_file() terminates the returned buffer with NUL
since late May 2005, there is no reason to copy it anymore.

If you pass it a filename without the "--" marker to separate it from
revision information and flags, we now require that the file in question
actually exists. This makes mis-typed revision information not be silently
just considered a strange filename.

With the "--" marker, you can continue to pass in filenames that do not
actually exists - useful for querying what happened to a file that you
no longer have in the repository.

[ All scripts should use the "--" format regardless, to make things
  unambiguous. So this change should not affect any existing tools ]

Without this, there is no way to specify a remote executable when
invoking git-pull/git-fetch as there is for git-clone.

[jc: I have a mild suspicion that this is a broken environment (aka
 sysadmin disservice).  It may be legal to configure your sshd to
 spawn named program without involving shell at all, and if your
 sysadmin does so and you have your git programs under your home
 directory, you would need something like this, but then I suspect
 you would need such workaround everywhere, not just git. But we
 have these options we can use to work around the issue, so there
 is no strong reason not to reject this patch, either. ]

This is the update hook we use in all our git-repos.

It has some improvements over the original version, namely:
* Don't send every commit since dawn of time when adding a new tag.
* When updating an annotated tag, just send the diffs since the last tag.
* Add diffstat output for 'normal' commits (top) and annotated tags (bottom).
* Block un-annotated tags in shared repos.

I'm a bit uncertain about that last one, but it demonstrates how to
disallow updates of a ref which we use, so I kept it.

Note that git-describe is needed for the "changes since last annotated tag"
thing to work.

It is a common mistake to leave an unsed `origin` branch behind
if a shared public repository was created by first cloning from
somewhere else.  Subsequent `git push` into it with the default
"push all the matching ref" would push the `origin` branch from
the developer repository uselessly.

The current Documentation/tutorial.txt concentrates on the lower-level
git interfaces.  So it's useful to people developing alternative
porcelains, to advanced users, etc., but not so much to beginning users.

I think it makes sense for the main tutorial to address those
beginnning users, so with this patch I'm proposing that we move
Documentation/tutorial.txt to Documentation/core-tutorial.txt and
replace it by a new tutorial.

We forgot to make sure that there is no more than one pattern
parameter.  Also when looking for files in a directory called
'--others', it passed that path limiter without preceding the
end-of-options marker '--' to underlying git-ls-files, which
misunderstood it as one of its options instead.

	$ git grep --others -e Meta/Make Meta
	$ git grep -o -e Meta/Make Meta
	$ git grep -o Meta/Make Meta

look for a string "Meta/Make" from untracked files in Meta/
directory.

	$ git grep Meta/Make --others

looks for the same string from tracked files in ./--others
directory.

On the other hand,

	$ git grep -e Meta/Make --others

does not have a freestanding pattern, so everybody is parameter
and there is no path specifier.  It looks for the string in all
the untracked files without any path limiter.

When overriding DT_* macro detection with NO_D_TYPE_IN_DIRENT (recent
Cygwin build problem, which hopefully is already fixed in their CVS
snapshot version), we define DTYPE() macro to return just "we do not
know", but still needed to use DT_* macro to avoid ifdef in the code
we use them.  If the platform defines DT_* macro but with unusable
d_type, this would have resulted in us redefining these preprocessor
symbols.

Admittedly, that would be just a couple of compilation warnings, and
on Cygwin at least this particular problem is transitory (the problem
is already fixed in their CVS snapshot version), so this is a low
priority fix.

This test depended on "sleep 1" to be enough to dirty the index
entry for a symlink.  Alex noticed that on his Cygwin installation
"sleep 1" was sometimes not enough, and after further discussion with
Christopher Faylor, it was brought up that on FAT filesystem timestamp
granularity is 2 seconds so sleeping 1 second is not enough.

For now this patch takes an easy workaround of sleeping for 3 seconds.

Very strictly speaking, POSIX requires lstat to fill only S_IFMT part
of st_mode and st_size for symlinks, and depending on timestamp might
be considered a bug, but we depend on that anyway, so it is better to
test that.

The recent Cygwin defines DT_UNKNOWN although it does not have d_type
in struct dirent.  Give an option to tell us not to use d_type on such
platforms.  Hopefully this problem will be transient.
Signed-off-by: NJunio C Hamano <junkio@cox.net>

The d_ino field is only used for performance reasons in
fsck-objects.  On a typical filesystem, i-number tends to have a
strong correlation with where the actual bits sit on the disk
platter, and we sort the entries to allow us scan things that
ought to be close together together.

If the platform lacks support for it, it is not a big deal.
Just do not use d_ino for sorting, and scan them unsorted.
