This emulation of poll() is by far not general. It assumes that the

In order not to needlessly burn CPU time, the CPU is yielded to other
processes before the next round in the poll loop using Sleep(0). Note that

* When -- appears, revs come before it, and paths come after it;

that is not the case. We tell the user to disambiguate by using -- in
such a case.

When this rule is applied to "reset", because we can have only zero or one

We have to check only the first one or two tokens after the command name

-- A:
no explicit rev given; "A" and whatever follows it are paths.
A --:
explicit rev "A" given and whatever follows the "--" are paths.
A B:
"A" could be rev or path and we need to guess. "B" could
be missing but if exists that (and everything that follows) would
be paths.
So we apply the guess only in the last case and only to "A" (not "B" and
what comes after it).

everything that follows) are reset to the HEAD revision.
* If "A" is unambiguously a rev, on the other hand, the index entries for

a pack becomes corrupted. This is especially true when an object exists

there is no way to retrieve the former object even if the later is
available in another pack or loose.
This patch allows for a delta to be resolved (with a performance cost)
using a base object from a source other than the pack where that delta
is located. Same thing for non-delta objects: rather than failing
outright, a search is made in other packs or used loose when the
currently active pack has it but corrupted.
Of course git will become extremely noisy with error messages when that
happens. However, if the operation succeeds nevertheless, a simple
'git repack -a -f -d' will "fix" the corrupted repository given that all
corrupted objects have a good duplicate somewhere in the object store,

git-svn: make rebuild respect rewriteRoot option
Suppose someone fetches git-svn-ified commits from another repo and then
attempts to use 'git-svn init --rewrite-root=foo bar'. Using git svn rebase
after that will fail badly:
* For each commit tried by working_head_info, rebuild is called indirectly.
* rebuild will iterate over all commits and skip all of them because the
URL does not match. Because of that no rev_map file is generated at all.
* Thus, rebuild will run once for every commit. This takes ages.
* In the end there still isn't any rev_map file and thus working_head_info
fails.
Addressing this behaviour fixes an apparently not too uncommon problem with
providing git-svn mirrors of Subversion repositories. Some repositories are
accessed using different URLs depending on whether the user has push
privileges or not. In the latter case, an anonymous URL is often used that
differs from the push URL. Providing a mirror that is usable in both cases
becomes a lot more possible with this change.

Windows: Implement start_command().
On Windows, we have spawnv() variants to run a child process instead of
fork()/exec(). In order to attach pipe ends to stdin, stdout, and stderr,
we have to use this idiom:
i.e. the child process closes the both pipe ends after duplicating one
to the file descriptors where they are needed.
On Windows, which does not have fork(), we never have an opportunity to
(1) duplicate a pipe end in the child, (2) close unused pipe ends. Instead,
we must use this idiom:
i.e. save away the descriptor at the destination slot, replace by the pipe
end, spawn process, restore the saved file.
But there is a problem: Notice that the child did not only inherit the
dup2()ed descriptor, but also *both* original pipe ends. Although the one
end that was dup()ed could be closed before the spawn(), we cannot close
the other end - the child inherits it, no matter what.
The solution is to generate non-inheritable pipes. At the first glance,
this looks strange: The purpose of pipes is usually to be inherited to
child processes. But notice that in the course of actions as outlined
above, the pipe descriptor that we want to inherit to the child is
dup2()ed, and as it so happens, Windows's dup2() creates inheritable
duplicates.

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).

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).

Documentation: fix formatting in git-svn
Due to a misplaced list block separator, general hints about the config
file options got indented at the same level as the description of the last
option, making it easy to miss them.

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.

Teach "git clone" to pack refs
In repos with many refs, it is unlikely that most refs will ever change.
This fact is already exploited by "git gc" by executing "git pack-refs"
to consolidate all refs into a single file.
When cloning a repo with many refs, it does not make sense to create the
loose refs in the first place, just to have the next "git gc" consolidate
them into one file. Instead, make "git clone" create the packed refs file
immediately, and forego the loose refs completely.

Prepare testsuite for a "git clone" that packs refs
t5515-fetch-merge-logic removes many, but not all, refs between each test.
This is done by removing the corresponding refs/foo/* files in the .git/refs
hierarchy. However, once "git clone" starts producing packed refs, these refs
will no longer be in the .git/refs hierarchy, but rather listed in
.git/packed-refs. This patch teaches t5515-fetch-merge-logic to remove the
refs using "git update-ref -d" which properly handles packed refs.

Move pack_refs() and friends into libgit
This moves pack_refs() and underlying functionality into the library,
to make pack-refs functionality easily available to all git programs.
Most of builtin-pack-refs.c has been moved verbatim into a new file
pack-refs.c that is compiled into libgit.a. A corresponding header
file, pack-refs.h, has also been added, declaring pack_refs() and
the #defines associated with the flags parameter to pack_refs().
This patch introduces no other changes in functionality.

Incorporate fetched packs in future object traversal
Immediately after fetching a pack, we should call reprepare_packed_git() to
make sure the objects in the pack are reachable. Otherwise, we will fail to
look up objects that are present only in the fetched pack.
