show: suppress extra newline when showing annotated tag
When showing a tag, our header parsing finishes with the
offset pointing to the newline separating the tag header
from the tag body. This means that the printed body will
always start with a newline.
However, we also add an extra newline when printing the
tagger information. This leads to an ugly double-newline:
$ git show v1.6.3
tag v1.6.3
Tagger: Junio C Hamano <gitster@pobox.com>
Date: Wed May 6 18:16:47 2009 -0700
GIT 1.6.3
-----BEGIN PGP SIGNATURE-----
...
This patch removes the extra newline from the end of the
tagger headers. This is a better solution than suppressing
the separator newline, because it retains the behavior for
tags which have no tagger. E.g., "git show v0.99" will
continue to look like:
$ git show v0.99
tag v0.99
Test-release for wider distribution.

Some mailing lists are configured add prefix "[listname] " to all their
messages, and also people hand-edit subject lines, be it an output from
format-patch or a patch generated by some other means.
We cannot stop people from mucking with the subject line, and with the
change, there always will be need for hand editing the subject when that
happens. People have depended on the leading [bracketed string] removal.
In our 'oneway_merge()' we always do an 'lstat()' to see if we might
need to mark the entry for updating.
But we really shouldn't need to do that when the cache entry is already
marked as being ce_uptodate(), and this makes us do unnecessary lstat()
calls if we have index preloading enabled.

Improve on the 'invalid object' error message at commit time
Not that anybody should ever get it, but somebody did (probably because
of a flaky filesystem, but whatever). And each time I see an error
message that I haven't seen before, I decide that next time it will look
better.
So this makes us write more relevant information about exactly which
file ended up having issues with a missing object. Which will tell
whether it was a tree object, for example, or just a regular file in the
index (and which one).

as an odd way of asking for a log. I realize I should just have used "git
log", but at the same time it does make perfect conceptual sense. After
all, you _could_ have done
git show HEAD HEAD~1 HEAD~2 HEAD~3 HEAD~4
and saying "git show HEAD~5.." is pretty natural. It's not like "git show"
only ever showed a single commit (or other object) before either! So
conceptually, giving a commit range is a very sensible operation, even
though you'd traditionally have used "git log" for that.
However, doing that currently results in an error
fatal: object ranges do not make sense when not walking revisions
which admittedly _also_ makes perfect sense - from an internal git
implementation standpoint in 'revision.c'.
However, I think that asking to show a range makes sense to a user, while
saying "object ranges no not make sense when not walking revisions" only
makes sense to a git developer.
So on the whole, of the two different "makes perfect sense" behaviors, I
think I originally picked the wrong one. And quite frankly, I don't really
see anybody actually _depending_ on that error case. So why not change it?
So rather than error out, just turn that non-walking error case into a
"silently turn on walking" instead.

git-svn: Fix branch detection when repository root is inaccessible
For the case of multiple projects sharing a single SVN repository, it is
common practice to create the standard SVN directory layout within a
subdirectory for each project. In such setups, access control is often
used to limit what projects a given user may access. git-svn failed to
detect branches (e.g. when passing --stdlayout to clone) because it
relied on having access to the root directory in the repository. This
patch solves this problem by making git-svn use paths relative to the
given repository URL instead of the repository root.

quickfetch(): Prevent overflow of the rev-list command line
quickfetch() calls rev-list to check whether the objects we are about to
fetch are already present in the repo (if so, we can skip the object fetch).
However, when there are many (~1000) refs to be fetched, the rev-list
command line grows larger than the maximum command line size on some systems
(32K in Windows). This causes rev-list to fail, making quickfetch() return
non-zero, which unnecessarily triggers the transport machinery. This somehow
causes fetch to fail with an exit code.
By using the --stdin option to rev-list (and feeding the object list to its
standard input), we prevent the overflow of the rev-list command line,
which causes quickfetch(), and subsequently the overall fetch, to succeed.
However, using rev-list --stdin is not entirely straightforward: rev-list
terminates immediately when encountering an unknown object, which can
trigger SIGPIPE if we are still writing object's to its standard input.
We therefore temporarily ignore SIGPIPE so that the fetch process is not
terminated.
The patch also contains a testcase to verify the fix (note that before
the patch, the testcase would only fail on msysGit).

guarantees that the 'lstat()' of the path would match, it also means
that we know that people haven't played games with moving directories

When a git command executes a subcommand, it uses the "git
foo" form, which relies on finding "git" in the PATH.
Normally this should not be a problem, since the same "git"
that was used to invoke git in the first place will be
found. And if somebody invokes a "git" outside of the PATH
(e.g., by giving its absolute path), this case is already
covered: we put that absolute path onto the front of PATH.
However, if one is using "sudo", then sudo will execute the
"git" from the PATH, but pass along a restricted PATH that
may not contain the original "git" directory. In this case,
executing a subcommand will fail.
To solve this, we put the "git" wrapper itself into the
execdir; this directory is prepended to the PATH when git
starts, so the wrapper will always be found.

Add 'fill_directory()' helper function for directory traversal
Most of the users of "read_directory()" actually want a much simpler
interface than the whole complex (but rather powerful) one.
In fact 'git add' had already largely abstracted out the core interface
issues into a private "fill_directory()" function that was largely
applicable almost as-is to a number of callers. Yes, 'git add' wants to
do some extra work of its own, specific to the add semantics, but we can
easily split that out, and use the core as a generic function.
This function does exactly that, and now that much simplified
'fill_directory()' function can be shared with a number of callers,
while also ensuring that the rather more complex calling conventions of
read_directory() are used by fewer call-sites.
This also makes the 'common_prefix()' helper function private to dir.c,
since all callers are now in that file.

git-format-patch prepends patches with a [PATCH x/n] prefix, but
mailinfo used to remove any number of square-bracket pairs and
the content between them. This prevents one from using a commit
subject like this:
[ and ] must be allowed as input
Removing the square bracket pair from this rather clumsily
constructed subject line loses important information, so we must
take care not to.
This patch causes the subject stripping to stop after it has
encountered one pair of square brackets.
One possible downside of this patch is that the patch-handling
programs will now fail at removing author-added square-brackets
to be removed, such as
[RFC][PATCH x/n]
However, since format-patch only adds one set of square brackets,
this behaviour is quite easily undesrstood and defended while the
previous behaviour is not.

Factor out pre context line handling into the new function
show_pre_context() and change the algorithm to rewind by looking for
newline characters and roll forward again, instead of maintaining an

zero. Normally, there are far more non-matching lines, so the time
spent in total decreases.

git.c: avoid allocating one-too-many elements for new argv array
When creating a new argv array from a configured alias and the supplied
command line arguments, the new argv was allocated with one element too
many. Since the first element of the original argv array is skipped when
copying it to the new_argv, the number of elements that are allocated
should be reduced by one. 'count' is the number of elements that new_argv
contains, and *argcp is the number of elements in the original argv array.
So the total allocation (including the terminating NULL entry) for the
new_argv array should be:
count + (*argcp - 1) + 1
Also, the explicit assignment of the NULL terminating entry can be avoided
by just copying it over from the original argv array.

git log: add '--merges' flag to match '--no-merges'
I do various statistics on git, and one of the things I look at is merges,
because they are often interesting events to count ("how many merges vs
how much 'real development'" kind of statistics). And you can do it with
some fairly straightforward scripting, ie
git rev-list --parents HEAD |
grep ' .* ' |
git diff-tree --always -s --pretty=oneline --stdin |
less -S
will do it.
But I finally got irritated with the fact that we can skip merges with
'--no-merges', but we can't do the trivial reverse operation.
So this just adds a '--merges' flag that _only_ shows merges. Now you can
do the above with just a
git log --merges --pretty=oneline
which is a lot simpler. It also means that we automatically get a lot of
statistics for free, eg
git shortlog -ns --merges
does exactly what you'd want it to do.
