At present, it is sufficient to ensure that an error return
from inflateInit() is not ignored. Most error returns, like

Precompute the fanout decoding and the oid offset in a pack-*.idx
The fanout table is fairly commonly accessed, we need to read it
twice for each object we lookup in any given pack file. Most of
the processors running Git are running in little-endian mode, as
they are variants of the x86 platform, so reading the fanout is
a costly operation as we need to convert from network byte order
to local byte order. By decoding the fanout table into a malloc
obtained buffer we can save these 2 decode operations per lookup
and make search go more quickly.
This also cleans up the initialization of the search functions
by cutting out a few instructions, saving a small amount of time.

Add basic support to read pack-*.idx v1 and v2 files
The index data is mapped into memory and then scanned using a
binary search algorithm to locate the matching entry for the
supplied git_oid. The standard fanout hash trick is applied to
reduce the search space by 8 iterations.
Since the v1 and v2 file formats differ in their search function,
due to the different layouts used for the object records, we use
two different search implementations and a virtual function pointer
to jump to the correct version of code for the current pack index.
The single function jump per-pack should be faster then computing
a branch point inside the inner loop of a common binary search.
To improve concurrency during read operations the pack lock is only
held while verifying the index is actually open, or while opening
the index for the first time. This permits multiple concurrent
readers to scan through the same index.
If an invalid index file is opened we close it and mark the
git_pack's invalid bit to true. The git_pack structure is kept
around in its parent git_packlist, but the invalid bit will cause
all future readers to skip over the pack entirely. Pruning the
invalid entries is relatively unimportant because they shouldn't
be very common, a $GIT_DIRECTORY/objects/pack directory tends to
only have valid pack files.

Refactor pack memory management and locking to be safer
Using an atomic reference counter is difficult to make
cross-platform, as the reference count implementations
are generally processor specific. Its also hard to do
a proper multi-read/single-write implementation.
We now use a simple mutex around the reference count for the list
of packs. Readers grab the mutex and either build the list, or
increment the existing one's reference count. When the reader is
done with the list, the reference count is decremented. In this way
parallel readers are able to operate on the list without worrying
about it being deallocated out from under them.
Individual pack structures are held by reference counts, but we
only care about the list the pack structure is held in. There is
no need to increment/decrement the pack reference counts as we
scan through them during a read operation, the caller holds the
git_packlist and that is sufficient to hold the packs it references.

Our fileops API is currently private. We aren't planning on supplying

we'd probably whole-sale publish fileops, not just the dirent code.
By moving it to be private we can also change the call signature to
permit the buffer to be passed down through the call chain. This is
very helpful when we are doing a recursive scan as we can reuse just
one buffer in all stack frames, reducing the impact the recursion has
on the stack frames in the data cache.

In the future once we have pack objects in memory we are likely
to enhance these routines with garbage collection logic to purge
cached pack data when allocations fail. Because the size of the
function will grow somewhat large, we don't want to mark them for
inline as gcc tends to aggressively inline, creating larger than

Support building on Mac OS X by using pthread_getspecific for TLS
The Mach-O format does not permit gcc to implement the __thread
TLS specification, so we must instead emulate it using a single
int cell allocated from memory and stored inside of the thread
specific data associated with the current pthread.
What makes this tricky is git_errno must be a valid lvalue, so
we really need to return a pointer to the caller and deference it
as part of the git_errno macro.
The GCC-specific __attribute__((constructor)) extension is used
to ensure the pthread_key_t is allocated before any Git functions
are executed in the library, as this is necessary to access our
thread specific storage.

calls malloc() with a zero size allocation request. Standard C
says that the behaviour of malloc() in this case is implementation
defined.
[C99, 7.20.3 says "... If the size of the space requested is zero,
the behavior is implementation-defined: either a null pointer is
returned, or the behavior is as if the size were some nonzero
value, except that the returned pointer shall not be used to
access an object."]

Use cgcc in the sparse target
cgcc is the recommended way to run sparse, since it provides
many -Defines suitable to the given gcc platform. For example,
on some Ubuntu/glibc versions, a plain sparse invocation gives
the following warning:
"warning: This machine appears to be neither x86_64 nor i386."
Using "cgcc -no-compile" instead eliminates this warning.

Since at least MS have something like GetFirstDirEnt() and
GetNextDirEnt() (presumably with superior performance), we
can let MS hackers add support for a dirent walker using

readdir() calls.

Add an io caching layer to the gitfo api
The idea is taken from Junio's work in read-cache.c, where
it's used for writing out the index without tap-dancing on
the poor harddrive. Since it's almost certainly useful for
cached writing of packfiles too, we turn it into a generic
API, making it perfectly simple to reuse it later.
gitfo_write_cached() has the same contract as gitfo_write(), it
returns GIT_SUCCESS if all bytes are successfully written (or were
at least buffered for later writing), and <0 if an error occurs
during buffer writing.

Remove config.h and make fileops an internal API
Since it doesn't make sense to make the disk access stuff
portable *AND* public (that's a job for each application
imo), we can take a shortcut and just support unixy stuff
for now and get away with coding most of it as macros.
Since we go with an internal API for starters and only
provide higher-level API's to the libgit users, we'll be
ok with this approach.

$(BASIC_CFLAGS) as well as userdefined $(CFLAGS) and then
consistently uses that variable where both were used anyway.

s/git_revp/git_revpool/
git_revp is something I personally can't stop pronouncing
"rev pointer". I'm sure others would suffer the same
problem.
Also, rename the git_revp_ sub-api "gitrp_". This is the
first of many such renames, primarily done to prevent
extreme inflation in the "git_" namespace, which we'd like
to reserve for a higher-level API.
While we're at it, we remove the noise-char "c" from a lot
of functions. Since revision walking is all about commits,
the common case should be that we're dealing with commits.
Exceptions can get a more mnemonic description as needed.

It doesn't cover all cases, but we can work on those as
we go along. For now, gcc, MSVC++, Intel C/C++, IBM XL C/C++,
Sun Studio C/C++ and Borland C++ Builder are the supported
compilers (although we boldly assume that they all are of
a recent enough version to support thread-local storage).
This is intended to be used in upcoming patches that implement
graceful (but TLS-dependant) error-handling in the library.

from git.git to detect the number of usable cpu's.

It's arguably smoother to keep them close to the source,
as that's where one's working when modifying them. More

get to the public API at the same time.
