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.

bfce5087ee Makefile: fix shell quoting
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
(and the first level of quoting itself) from the shell that runs the
"echo" inside the Makefile.

You can test this by trying:

    $ ln -s /bin/tar "$HOME/Tes' program/tar"
    $ make TAR="$HOME/Tes' program/tar" test

c455c87c5c Rename path_list to string_list
The name path_list was correct for the first usage of that data structure,
but it really is a general-purpose string list.

$ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list)
$ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list)
$ git mv path-list.h string-list.h
$ git mv path-list.c string-list.c
$ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path)
$ perl -i -pe 's/path/string/g' string-list.[ch]
$ git mv Documentation/technical/api-path-list.txt \
	Documentation/technical/api-string-list.txt
$ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths)

... and then fix all users of string-list to access the member "string"
instead of "path".

Documentation/technical/api-string-list.txt needed some rewrapping, too.

7856844823 Link git-shell only to a subset of libgit.a
Commit 5b8e6f85 introduced stubs for three functions that make no sense
for git-shell. But those stubs defined libgit.a functions a second time
so that a linker can complain.

Now git-shell is only linked to a subset of libgit.a.

5b8e6f85f9 shrink git-shell by avoiding redundant dependencies
A lot of modules that have nothing to do with git-shell functionality
were linked in, bloating git-shell more than 8 times.

This patch cuts off redundant dependencies by:
1. providing stubs for three functions that make no sense for git-shell;
2. moving quote_path_fully from environment.c to quote.c to make the
   later self sufficient;
3. moving make_absolute_path into a new separate file.

The following numbers have been received with the default optimization
settings on master using GCC 4.1.2:

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).

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.

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().

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

                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

In the same repository:

    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.

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.

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/

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 makes write_tree_from_memory(), which writes the active cache as

also makes available merge_trees(), which does the internal merge of
two trees with a known base, and merge_recursive(), which does the
recursive internal merge of two commits with a list of common
ancestors.

The first two of these will be used by checkout -m, and the third is
presumably useful in general, although the implementation of checkout
-m which entirely matches the behavior of the shell version does not
use it (since it ignores the difference of ancestry between the old
branch and the new branch).

43fe901b71 compat: Add simplified merge sort implementation from glibc
qsort in Windows 2000 (and various other C libraries) is a Quicksort
with the usual O(n^2) worst case.  Unfortunately, sorting Git trees
seems to get very close to that worst case quite often:

    $ /git/gitbad runstatus
    # On branch master
    qsort, nmemb = 30842
    done, 237838087 comparisons.

This patch adds a simplified version of the merge sort that is glibc's
qsort(3).  As a merge sort, this needs a temporary array equal in size
to the array that is to be sorted, but has a worst-case performance of
O(n log n).

The complexity that was removed is:

* Doing direct stores for word-size and -aligned data.
* Falling back to quicksort if the allocation required to perform the
  merge sort would likely push the machine into swap.

Even with these simplifications, this seems to outperform the Windows
qsort(3) implementation, even in Windows XP (where it is "fixed" and
doesn't trigger O(n^2) complexity on trees).

482cce8205 help: make 'git-help--browse' usable outside 'git-help'.
"git-help--browse" helper is to launch a browser of the user's choice
to view the HTML version of git documentation for a given command.  It
used to take the name of a command, convert it to the path of the
documentation by prefixing the directory name and appending the
".html" suffix, and start the browser on the path.

This updates the division of labor between the caller in help.c and
git-help--browser helper.  The helper is now responsible for launching
a browser of the user's choice on given URLs, and it is the caller's
responsibility to tell it the paths to documentation files.

This is in preparation to reuse the logic to choose user's preferred
browser in instaweb.

The helper had a provision for running it without any command name, in
which case it showed the toplevel "git(7)" documentation, but the
caller in help.c never makes such a call.  The helper now exits with a
usage message when no path is given.

2600973f2c pre-POSIX.1-2001 systems do not have <sys/select.h>
POSIX.1-2001 has declaration of select(2) in <sys/select.h>, but
in the previous version of SUS, it was declared in <sys/time.h>
(which is already included in git-compat-util.h).

This introduces NO_SYS_SELECT_H macro in the Makefile to be set
on older systems, to skip inclusion of <sys/select.h> that does
not exist on them.

We could check _POSIX_VERSION with 200112L and do this
automatically, but earlier it was reported that the approach
does not work well on some vintage of HP-UX.  Other systems may
get _POSIX_VERSION itself wrong.  At least for now, this manual
configuration is safer.

181256442e Move sha1_file_to_archive into libgit
When the specfile (export-subst) attribute was introduced, it added a
dependency from archive-{tar|zip}.c to builtin-archive.c. This broke the
support for archive-operations in libgit.a since builtin-archive.o doesn't
belong in libgit.a.

This patch moves the functions required by libgit.a from builtin-archive.c
to the new file archive.c (which becomes part of libgit.a).

5d6491c7c7 git-help: add -w|--web option to display html man page in a browser.
Now when using "git help -w cmd", we will try to show the HTML man
page "git-cmd.html" in your prefered web browser.

To do that "help.c" code will call a new shell script
"git-browse-help".

This currently works only if the HTML versions of the man page
have been installed in $(htmldir) (typically "/usr/share/doc/git-doc"),
so new target to do that is added to "Documentation/Makefile".

The browser to use can be configured using the "web.browser"
config variable.

We try to open a new tab in an existing web browser, if possible.

The code in "git-browse-help" is heavily stolen from "git-mergetool"
by Theodore Y. Ts'o. Thanks.

cf1b7869f0 Use gitattributes to define per-path whitespace rule
The `core.whitespace` configuration variable allows you to define what
`diff` and `apply` should consider whitespace errors for all paths in
the project (See gitlink:git-config[1]).  This attribute gives you finer
control per path.

For example, if you have these in the .gitattributes:

    frotz   whitespace
    nitfol  -whitespace
    xyzzy   whitespace=-trailing

all types of whitespace problems known to git are noticed in path 'frotz'
(i.e. diff shows them in diff.whitespace color, and apply warns about
them), no whitespace problem is noticed in path 'nitfol', and the
default types of whitespace problems except "trailing whitespace" are
noticed for path 'xyzzy'.  A project with mixed Python and C might want
to have:

    *.c    whitespace
    *.py   whitespace=-indent-with-non-tab

in its toplevel .gitattributes file.

This program dumps (parts of) a git repository in the format that

For clarity's sake, it does not use the 'inline' method of specifying
blobs in the commits, but builds the blobs before building the commits.

Since signed tags' signatures will not necessarily be valid (think
transformations after the export, or excluding revisions, changing
the history), there are 4 modes to handle them: abort (default),
ignore, warn and strip.  The latter just turns the tags into
unsigned ones.

113f10f22f Make git-clean a builtin
This replaces git-clean.sh with builtin-clean.c, and moves
git-clean.sh to the examples.

This also introduces a change in behavior when removing directories
explicitly specified as a path.  For example currently:

1. When dir has only untracked files, these two behave differently:

    $ git clean -n dir
    $ git clean -n dir/

the former says "Would not remove dir/", while the latter would say
"Would remove dir/untracked" for all paths under it, but not the
directory itself.

With -d, the former would stop refusing, however since the user
explicitly asked to remove the directory the -d is no longer required.

2. When there are more parameters:

    $ git clean -n dir foo
    $ git clean -n dir/ foo

both cases refuse to remove dir/ unless -d is specified.  Once again
since both cases requested to remove dir the -d is no longer required.

Thanks to Johannes Schindelin for the conversion to using the
parse-options API.

In a subsequent patch the path to the system-wide config file will be
computed. This is a preparation for that change. It turns all accesses
of ETC_GITCONFIG into function calls. There is no change in behavior.

As a consequence, config.c is the only file that needs the definition of
ETC_GITCONFIG. Hence, -DETC_GITCONFIG is removed from the CFLAGS and a
special build rule for config.c is introduced. As a side-effect, changing
the defintion of ETC_GITCONFIG (e.g. in config.mak) does not trigger a
complete rebuild anymore.

609a2289d7 Improve accuracy of check for presence of deflateBound.
ZLIB_VERNUM isn't defined in some zlib versions, so this patch does a proper
linking test in autoconf to see whether deflateBound exists in zlib. Also,
setting NO_DEFLATE_BOUND will also work for folk not using autoconf.

This actually replaces peek-remote with ls-remote, since peek-remote
now handles everything. peek-remote remains an a second name for
ls-remote, although its help message now gives the "ls-remote" name.

The file commit.c got quite large, but it does not have to be: the
code concerning pretty printing is pretty well contained.  In fact,
this commit just splits it off into pretty.c, leaving commit.c with
just 672 lines.

4a59fd1312 Add a simple option parser.
The option parser takes argc, argv, an array of struct option
and a usage string.  Each of the struct option elements in the array
describes a valid option, its type and a pointer to the location where the
value is written.  The entry point is parse_options(), which scans through
the given argv, and matches each option there against the list of valid
options.  During the scan, argv is rewritten to only contain the
non-option command line arguments and the number of these is returned.

Aggregation of single switches is allowed:
  -rC0 is the same as -r -C 0 (supposing that -C wants an arg).

Every long option automatically support the option with the same name,
prefixed with 'no-' to unset the switch. It assumes that initial value for
strings are "NULL" and for integers is "0".

Long options are supported either with '=' or without:
  --some-option=foo is the same as --some-option foo

9027f53cb5 Do linear-time/space rename logic for exact renames
This implements a smarter rename detector for exact renames, which
rather than doing a pairwise comparison (time O(m*n)) will just hash the
files into a hash-table (size O(n+m)), and only do pairwise comparisons
to renames that have the same hash (time O(n+m) except for unrealistic
hash collissions, which we just cull aggressively).

Admittedly the exact rename case is not nearly as interesting as the
generic case, but it's an important case none-the-less. A similar general
approach should work for the generic case too, but even then you do need
to handle the exact renames/copies separately (to avoid the inevitable
added cost factor that comes from the _size_ of the file), so this is
worth doing.

In the expectation that we will indeed do the same hashing trick for the
general rename case, this code uses a generic hash-table implementation
that can be used for other things too.  In fact, we might be able to
consolidate some of our existing hash tables with the new generic code
in hash.[ch].

d1a2057560 Fix generation of perl/perl.mak
The code generating perl/Makefile from Makefile.PL was causing trouble
because it didn't considered NO_PERL_MAKEMAKER and ran makemaker
unconditionally, rewriting perl.mak. Makemaker is FUBAR in ActiveState Perl,
and perl/Makefile has a replacement for it.

Besides, a changed Git.pm is *NOT* a reason to rebuild all the perl scripts,
so remove the dependency too.
