26141b5b60 parse-opt: fake short strings for callers to believe in.
If we begin to parse -abc and that the parser knew about -a and -b, it
will fake a -c switch for the caller to deal with.

Of course in the case of -acb (supposing -c is not taking an argument) the
caller will have to be especially clever to do the same thing. We could
think about exposing an API to do so if it's really needed, but oh well...

112db553b0 Shrink the git binary a bit by avoiding unnecessary inline functions
So I was looking at the disgusting size of the git binary, and even with
the debugging removed, and using -Os instead of -O2, the size of the text
section was pretty high. In this day and age I guess almost a megabyte of
text isn't really all that surprising, but it still doesn't exactly make
me think "lean and mean".

With -Os, a surprising amount of text space is wasted on inline functions
that end up just being replicated multiple times, and where performance
really isn't a valid reason to inline them. In particular, the trivial
wrapper functions like "xmalloc()" are used _everywhere_, and making them
inline just duplicates the text (and the string we use to 'die()' on
failure) unnecessarily.

So this just moves them into a "wrapper.c" file, getting rid of a tiny bit
of unnecessary bloat. The following numbers are both with "CFLAGS=-Os":

Before:
	[torvalds@woody git]$ size git
	   text	   data	    bss	    dec	    hex	filename
	 700460	  15160	 292184	1007804	  f60bc	git

After:
	[torvalds@woody git]$ size git
	   text	   data	    bss	    dec	    hex	filename
	 670540	  15160	 292184	 977884	  eebdc	git

so it saves almost 30k of text-space (it actually saves more than that
with the default -O2, but I don't think that's necessarily a very relevant
number from a "try to shrink git" standpoint).

It might conceivably have a performance impact, but none of this should be
_that_ performance critical. The real cost is not generally in the wrapper
anyway, but in the code it wraps (ie the cost of "xread()" is all in the
read itself, not in the trivial wrapping of it).

044bbbcb63 Make git_dir a path relative to work_tree in setup_work_tree()
Once we find the absolute paths for git_dir and work_tree, we can make
git_dir a relative path since we know pwd will be work_tree. This should
save the kernel some time traversing the path to work_tree all the time
if git_dir is inside work_tree.

Daniel's patch didn't apply for me as-is, so I recreated it with some
differences, and here are the numbers from ten runs each.

There is some IO for me - probably due to more-or-less random flushing of
the journal - so the variation is bigger than I'd like, but whatever:

	Before:
		real    0m8.135s
		real    0m7.933s
		real    0m8.080s
		real    0m7.954s
		real    0m7.949s
		real    0m8.112s
		real    0m7.934s
		real    0m8.059s
		real    0m7.979s
		real    0m8.038s

	After:
		real    0m7.685s
		real    0m7.968s
		real    0m7.703s
		real    0m7.850s
		real    0m7.995s
		real    0m7.817s
		real    0m7.963s
		real    0m7.955s
		real    0m7.848s
		real    0m7.969s

Now, going by "best of ten" (on the assumption that the longer numbers
are all due to IO), I'm saying a 7.933s -> 7.685s reduction, and it does
seem to be outside of the noise (ie the "after" case never broke 8s, while
the "before" case did so half the time).

So looks like about 3% to me.

Doing it for a slightly smaller test-case (just the "arch" subdirectory)
gets more stable numbers probably due to not filling the journal with
metadata updates, so we have:

	Before:
		real    0m1.633s
		real    0m1.633s
		real    0m1.633s
		real    0m1.632s
		real    0m1.632s
		real    0m1.630s
		real    0m1.634s
		real    0m1.631s
		real    0m1.632s
		real    0m1.632s

	After:
		real    0m1.610s
		real    0m1.609s
		real    0m1.610s
		real    0m1.608s
		real    0m1.607s
		real    0m1.610s
		real    0m1.609s
		real    0m1.611s
		real    0m1.608s
		real    0m1.611s

where I'ld just take the averages and say 1.632 vs 1.610, which is just
over 1% peformance improvement.

So it's not in the noise, but it's not as big as I initially thought and
measured.

(That said, it obviously depends on how deep the working directory path is
too, and whether it is behind NFS or something else that might need to
cause more work to look up).

e200783255 t7502-commit.sh: test_must_fail doesn't work with inline environment variables
When the arguments to test_must_fail() begin with a variable assignment,
test_must_fail() attempts to execute the variable assignment as a command.
This fails, and so test_must_fail returns with a successful status value
without running the command it was intended to test.

For example, the following script:

	#!/bin/sh
	test_must_fail () {
		"$@"
		test $? -gt 0 -a $? -le 129
	}
	foo='wo adrian'
	test_must_fail foo='yo adrian' sh -c 'echo foo: $foo'

always exits zero and prints the message:

	test.sh: line 3: foo=yo adrian: command not found

Test 16 calls test_must_fail in such a way and therefore has not been
testing whether git 'do[es] not fire editor in the presence of conflicts'.

A workaround is to set and export the variable in a normal way, not
using one-shot notation.  Because this would affect the remainder of
the process, the test is done inside a subshell.

9a7bbd1dd1 clean up error conventions of remote.c:match_explicit
match_explicit is called for each push refspec to try to
fully resolve the source and destination sides of the
refspec.  Currently, we look at each refspec and report
errors on both the source and the dest side before aborting.

It makes sense to report errors for each refspec, since an
error in one is independent of an error in the other.
However, reporting errors on the 'dst' side of a refspec if
there has been an error on the 'src' side does not
necessarily make sense, since the interpretation of the
'dst' side depends on the 'src' side (for example, when
creating a new unqualified remote ref, we use the same type
as the src ref).

This patch lets match_explicit return early when the src
side of the refspec is bogus. We still look at all of the
refspecs before aborting the push, though.

At the same time, we clean up the call signature, which
previously took an extra "errs" flag. This was pointless, as
we didn't act on that flag, but rather just passed it back
to the caller. Instead, we now use the more traditional
"return -1" to signal an error, and the caller aggregates
the error count.

This change fixes two bugs, as well:

  - the early return avoids a segfault when passing a NULL
    matched_src to guess_ref()

  - the check for multiple sources pointing to a single dest
    aborted if the "err" flag was set. Presumably the intent
    was not to bother with the check if we had no
    matched_src. However, since the err flag was passed in
    from the caller, we might abort the check just because a
    previous refspec had a problem, which doesn't make
    sense.

    In practice, this didn't matter, since due to the error
    flag we end up aborting the push anyway.

1a8fb155cf builtin-rerere: fix a small leak
The data read from MERGE_RR file is kept in path-list by hanging textual
40-byte conflict signature to path of the blob that contains the
conflict.  The signature is strdup'ed twice, and the second copy is given
to the path-list, leaking the first copy.

let's remove it.

516381d50b gitweb: quote commands properly when calling the shell
This eliminates the function git_cmd_str, which was used for composing
command lines, and adds a quote_command function, which quotes all of
its arguments (as in quote.c).

79c6dca413 sha1_file.c: simplify parse_pack_index()
It was implemented as a thin wrapper around an otherwise unused
helper function parse_pack_index_file().  The code becomes simpler
and easier to read by consolidating the two.
