daa0cc9a92 Build-in "git-shell"
This trivially makes "git-shell" a built-in.  It makes the executable even
fatter, though.

And MinGW removed git-shell only because of the funny dependencies; there
is no reason to do so anymore.

fdb2a2a600 compat: introduce on_disk_bytes()
Some platforms do not have st_blocks member in "struct stat"; mingw
already emulates it by rounding it up to closest 512-byte blocks (even
though it could overcount when a file has holes).

The reason to use the member is only to figure out how many kilobytes the
files occupy on-disk, so give a helper function in git-compat-util.h to
compute this value.

Current Makefile does not allow config.mak to override CC_LD_DYNPATH; it
only lets it affect indirectly via NO_R_TO_GCC_LINKER.

If the command line, config.mak or config.mak.autogen wants to set
CC_LD_DYNPATH differently, we should just allow it.

6dc4627ef4 Makefile: add a target which will abort compilation with ancient shells
This adds a make target which can be used to try to execute certain shell
constructs which are required for compiling and running git.

This patch provides a test for the $() notation for command substition
which is used in the Makefile and extensively in the git scripts.

The make target is named in such a way as to be a hint to the user that
SHELL_PATH should be set to an appropriate shell. If the shell command
fails, the user should receive a message similar to the following:

make: *** [please_set_SHELL_PATH_to_a_more_modern_shell] Error 2

In an earlier commit c70a8d9 (Makefile: Do not install a copy of 'git' in

49fa65a7a8 Allow the built-in exec path to be relative to the command invocation path
If GIT_EXEC_PATH (the macro that is defined in the Makefile) is relative,
it is interpreted relative to the command's invocation path, which usually
is $(bindir).

The Makefile rules were written with the assumption that $(gitexecdir) is
an absolute path. We introduce a separate variable that names the
(absolute) installation directory.

966c6edd31 Fix relative built-in paths to be relative to the command invocation
$(gitexecdir) (as defined in the Makefile) has gained another path
component, but the relative paths in the MINGW section of the Makefile,
which are interpreted relative to it, do not account for it.

Instead of adding another ../ in front of the path, we change the code that
constructs the absolute paths to do it relative to the command's directory,
which is essentially $(bindir). We do it this way because we will also
allow a relative $(gitexecdir) later.

46beb55988 Makefile: Normalize $(bindir) and $(gitexecdir) before comparing
The install target needs to check whether the user has opted to make
$(gitexecdir) equal to $(bindir). It did so by a straight string
comparison. Since we are going to allow a relative $(gitexecdir), we have
to normalize paths before comparison, which we do with $(cd there && pwd).

The normalized paths are stored in shell variables. These we can now
reuse in the subsequent install statements, which conveniently shortens
the lines a bit.

c70a8d98a5 Makefile: Do not install a copy of 'git' in $(gitexecdir)
There is already a copy in $(bindir). A subsequent patch will enable git
to derive the exec-path from its invocation path. If git is invoked
recursively, the first invocation puts the exec-path into PATH, so that
the recursive invocation would find the instance in the exec-path. This
second instance would again try to derive an exec-path from its invocation
path, but would base its result on the wrong "bindir".

We do install the copy of git first, but remove it later, so that we can
use it as the source of the hardlinks for the builtins.

Makefile records paths to a few programs in GIT-BUILD-OPTIONS file.  These
paths need to be quoted twice: once to protect specials from the shell
that runs the generated GIT-BUILD-OPTIONS file, and again to protect them

"echo" inside the Makefile.

You can test this by trying:

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

f4626df51f Add target architecture MinGW.
With this change GIT can be compiled and linked using MinGW. Builtins
that only read the repository such as the log family and grep already
work.

Simple stubs are provided for a number of functions that the Windows C
runtime does not offer. They will be completed in later patches.
However, a fix for the snprintf/vsnprintf replacement is applied here
to avoid buffer overflows.

Dmitry Kakurin pointed out that access(..., X_OK) would always fails on

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.

457bb45291 Port to 12 other Platforms.
This patch adds support to compile and run git on 12 additional platforms.
The platforms are based on UNIX Systems Labs (USL)/Novell/SYS V code base.
The most common are Novell UnixWare 2.X.X, SCO UnixWare 7.X.X,
OpenServer 5.0.X, OpenServer 6.0.X, and SCO pre OSR 5 platforms.

Looking at the the various platform headers, I find:

	#if defined(_KERNEL) || !defined(_POSIX_SOURCE) \
	     && !defined(_POSIX_C_SOURCE) && !defined(_XOPEN_SOURCE)

which hides u_short and other typedefs that other header files on these
platforms depend on.  WIth _XOPEN_SOURCE defined, sources that include
system header files that depend on the typedefs such as u_short cannot be
compiled on these platforms.

__USLC__ indicates UNIX System Labs Corperation (USLC), or a Novell-derived
compiler and/or some SysV based OS's.

__M_UNIX indicates XENIX/SCO UNIX/OpenServer 5.0.7 and prior releases
of the SCO OS's.  It is used just like Apple and BSD, both of these
shouldn't have _XOPEN_SOURCE defined.

This is with suggestions and modifications from

Daniel Barkalow, Junio C Hamano, Thomas Harning, and Jeremy Maitin-Shepard.

628522ec14 sha1-lookup: more memory efficient search in sorted list of SHA-1
Currently, when looking for a packed object from the pack idx, a
simple binary search is used.

A conventional binary search loop looks like this:

        unsigned lo, hi;
        do {
                unsigned mi = (lo + hi) / 2;
                int cmp = "entry pointed at by mi" minus "target";
                if (!cmp)
                        return mi; "mi is the wanted one"
                if (cmp > 0)
                        hi = mi; "mi is larger than target"
                else
                        lo = mi+1; "mi is smaller than target"
        } while (lo < hi);
	"did not find what we wanted"

The invariants are:

  - When entering the loop, 'lo' points at a slot that is never
    above the target (it could be at the target), 'hi' points at
    a slot that is guaranteed to be above the target (it can
    never be at the target).

  - We find a point 'mi' between 'lo' and 'hi' ('mi' could be
    the same as 'lo', but never can be as high as 'hi'), and
    check if 'mi' hits the target.  There are three cases:

     - if it is a hit, we have found what we are looking for;

     - if it is strictly higher than the target, we set it to
       'hi', and repeat the search.

     - if it is strictly lower than the target, we update 'lo'
       to one slot after it, because we allow 'lo' to be at the
       target and 'mi' is known to be below the target.

    If the loop exits, there is no matching entry.

When choosing 'mi', we do not have to take the "middle" but
anywhere in between 'lo' and 'hi', as long as lo <= mi < hi is
satisfied.  When we somehow know that the distance between the
target and 'lo' is much shorter than the target and 'hi', we
could pick 'mi' that is much closer to 'lo' than (hi+lo)/2,
which a conventional binary search would pick.

This patch takes advantage of the fact that the SHA-1 is a good
hash function, and as long as there are enough entries in the
table, we can expect uniform distribution.  An entry that begins
with for example "deadbeef..." is much likely to appear much
later than in the midway of a reasonably populated table.  In
fact, it can be expected to be near 87% (222/256) from the top
of the table.

This is a work-in-progress and has switches to allow easier
experiments and debugging.  Exporting GIT_USE_LOOKUP environment
variable enables this code.

On my admittedly memory starved machine, with a partial KDE
repository (3.0G pack with 95M idx):

    $ GIT_USE_LOOKUP=t git log -800 --stat HEAD >/dev/null
    3.93user 0.16system 0:04.09elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k
    0inputs+0outputs (0major+55588minor)pagefaults 0swaps

Without the patch, the numbers are:

    $ git log -800 --stat HEAD >/dev/null
    4.00user 0.15system 0:04.17elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k
    0inputs+0outputs (0major+60258minor)pagefaults 0swaps

In the same repository:

    $ GIT_USE_LOOKUP=t git log -2000 HEAD >/dev/null
    0.12user 0.00system 0:00.12elapsed 97%CPU (0avgtext+0avgdata 0maxresident)k
    0inputs+0outputs (0major+4241minor)pagefaults 0swaps

Without the patch, the numbers are:

    $ git log -2000 HEAD >/dev/null
    0.05user 0.01system 0:00.07elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k
    0inputs+0outputs (0major+8506minor)pagefaults 0swaps

There isn't much time difference, but the number of minor faults
seems to show that we are touching much smaller number of pages,
which is expected.

96872bc200 Move name hashing functions into a file of its own
It's really totally separate functionality, and if we want to start
doing case-insensitive hash lookups, I'd rather do it when it's
separated out.

It also renames "remove_index_entry()" to "remove_name_hash()", because
that really describes the thing better. It doesn't actually remove the
index entry, that's done by "remove_index_entry_at()", which is something
very different, despite the similarity in names.

17a8b25005 gitweb: fallback to system-wide config file if default config does not exist
From a distribution point of view, configuration files for applications
should reside in /etc/.  On the other hand it's convenient for multiple
instances of gitweb (e.g. virtual web servers on a single machine) to have
a per-instance configuration file, just as gitweb currently supports
through the file gitweb_config.perl next to the cgi.

To support both at runtime, this commit introduces GITWEB_CONFIG_SYSTEM as
a system-wide configuration file which will be used as a fallback if the
config file sprecified throug GITWEB_CONFIG does not exist.

7cf7f54a65 use build-time SHELL_PATH in test scripts
The top-level Makefile now creates a GIT-BUILD-OPTIONS file
which stores any options selected by the make process that
may be of use to further parts of the build process.
Specifically, we store the SHELL_PATH so that it can be used
by tests to construct shell scripts on the fly.

The format of the GIT-BUILD-OPTIONS file is Bourne shell,
and it is sourced by test-lib.sh; all tests can rely on just
having $SHELL_PATH correctly set in the environment.

The GIT-BUILD-OPTIONS file is written every time the
toplevel 'make' is invoked. Since the only users right now
are the test scripts, there's no drawback to updating its
timestamp. If something build-related depends on this, we
can do a trick similar to the one used by GIT-CFLAGS.

94351118c0 make alias lookup a public, procedural function
This converts git_config_alias to the public alias_lookup
function. Because of the nature of our config parser, we
still have to rely on setting static data. However, that
interface is wrapped so that you can just say

  value = alias_lookup(key);

6c0f86943e Ensure 'make dist' compiles git-archive.exe on Cygwin
On Cygwin we have to use git-archive.exe as the target, otherwise
running 'make dist' does not compile git-archive in the current
directory.  That may cause 'make dist' to fail on a clean source
tree that has never been built before.

833e3df171 pack-objects: Add runtime detection of online CPU's
Packing objects can be done in parallell nowadays, but it's
only done if the config option pack.threads is set to a value
above 1. Because of that, the code-path used is often not the
most optimal one.

This patch adds a routine to detect the number of online CPU's
at runtime (online_cpus()). When pack.threads (or --threads=) is
given a value of 0, the number of threads is set to the number of
online CPU's. This feature is also documented.

As per Nicolas Pitre's recommendations, the default is still to
run pack-objects single-threaded unless explicitly activated,
either by configuration or by command line parameter.

The routine online_cpus() is a rework of "numcpus.c", written by
one Philip Willoughby <pgw99@doc.ic.ac.uk>. numcpus.c is in the
public domain and can presently be downloaded from
http://csgsoft.doc.ic.ac.uk/numcpus/

1736855c9b Add merge-subtree back
An earlier commit e1b3a2c (Build-in merge-recursive) made the
subtree merge strategy backend unavailable.  This resurrects
it.

A new test t6029 currently only tests the strategy is available,
but it should be enhanced to check the real "subtree" case.

782c2d65c2 Build in checkout
The only differences in behavior should be:

 - git checkout -m with non-trivial merging won't print out
   merge-recursive messages (see the change in t7201-co.sh)

 - git checkout -- paths... will give a sensible error message if
   HEAD is invalid as a commit.

 - some intermediate states which were written to disk in the shell
   version (in particular, index states) are only kept in memory in
   this version, and therefore these can no longer be revealed by
   later write operations becoming impossible.

 - when we change branches, we discard MERGE_MSG, SQUASH_MSG, and
   rr-cache/MERGE_RR, like reset always has.

I'm not 100% sure I got the merge recursive setup exactly right; the
base for a non-trivial merge in the shell code doesn't seem
theoretically justified to me, but I tried to match it anyway, and the
tests all pass this way.

Other than these items, the results should be identical to the shell
version, so far as I can tell.

This introduces branch.{c,h} library files for doing porcelain-level

default configuration).
