1b19ccd236 tests: skip perl tests if NO_PERL is defined
These scripts all test git programs that are written in
perl, and thus obviously won't work if NO_PERL is defined.
We pass NO_PERL to the scripts from the building Makefile
via the GIT-BUILD-OPTIONS file.

499c29394c Makefile: allow building without perl
For systems with a missing or broken perl, it is nicer to
explicitly say "we don't want perl" because:

  1. The Makefile knows not to bother with Perl-ish things
     like Git.pm.

  2. We can print a more user-friendly error message
     than "foo is not a git command" or whatever the broken
     perl might barf

  3. Test scripts that require perl can mark themselves and
     such and be skipped

This patch implements parts (1) and (2). The perl/
subdirectory is skipped entirely, gitweb is not built, and
any git commands which rely on perl will print a
human-readable message and exit with an error code.

This patch is based on one from Robin H. Johnson.

1bf072e366 bisect--helper: implement "git bisect--helper"
This patch implements a new "git bisect--helper" builtin plumbing
command that will be used to migrate "git-bisect.sh" to C.

We start by implementing only the "--next-vars" option that will
read bisect refs from "refs/bisect/", and then compute the next
bisect step, and output shell variables ready to be eval'ed by
the shell.

At this step, "git bisect--helper" ignores the paths that may
have been put in "$GIT_DIR/BISECT_NAMES". This will be fixed in a
later patch.

b130a72b27 MinGW: implement mmap
Add USE_WIN32_MMAP which triggers the use of windows' native
file memory mapping functionality in git_mmap()/git_munmap() functions.

As git functions currently use mmap with MAP_PRIVATE set only, this
implementation supports only that mode for now.

On Windows, offsets for memory mapped files need to match the allocation
granularity. Take this into account when calculating the packed git-
windowsize and file offsets. At the moment, the only function which makes
use of offsets in conjunction with mmap is use_pack() in sha1-file.c.

Git fast-import's code path tries to map a portion of the temporary
packfile that exceeds the current filesize, i.e. offset+length is
greater than the filesize. The NO_MMAP code worked with that since pread()
just reads the file content until EOF and returns gracefully, while
MapViewOfFile() aborts the mapping and returns 'Access Denied'.
Working around that by determining the filesize and adjusting the length
parameter.

d7371a2d4d Makefile: Set compiler switch for USE_NSEC
The comments indicated that setting a Makefile variable USE_NSEC would
enable the code for sub-second [cm]times.  However, the Makefile
variable was never turned into a compiler switch so the code was never
enabled.  This patch allows USE_NSEC to be noticed by the compiler.

c567383b1e Create USE_ST_TIMESPEC and turn it on for Darwin
Not all OSes use st_ctim and st_mtim in their struct stat.  In
particular, it appears that OS X uses st_*timespec instead.  So add a
Makefile variable and #define called USE_ST_TIMESPEC to switch the
USE_NSEC defines to use st_*timespec.

This also turns it on by default for OS X (Darwin) machines.  Likely
this is a sane default for other BSD kernels as well, but I don't have
any to test that assumption on.

c06ff4908b Record ns-timestamps if possible, but do not use it without USE_NSEC
Traditionally, the lack of USE_NSEC meant "do not record nor use the
nanosecond resolution part of the file timestamps".  To avoid problems on
filesystems that lose the ns part when the metadata is flushed to the disk
and then later read back in, disabling USE_NSEC has been a good idea in
general.

If you are on a filesystem without such an issue, it does not hurt to read
and store them in the cached stat data in the index entries even if your
git is compiled without USE_NSEC.  The index left with such a version of
git can be read by git compiled with USE_NSEC and it can make use of the
nanosecond part to optimize the check to see if the path on the filesystem
hsa been modified since we last looked at.

119c8eeede add basic http clone/fetch tests
This was mostly being tested implicitly by the "http push"
tests. But making a separate test script means that:

  - we will run fetch tests even when http pushing support
    is not built

  - when there are failures on fetching, they are easier to
    see and isolate, as they are not in the middle of push
    tests

This script defaults to running the webserver on port 5550,
and puts the original t5540 on port 5540, so that the two
can be run simultaneously without conflict (but both still
respect an externally set LIB_HTTPD_PORT).

901c369af5 Support coverage testing with GCC/gcov
With gcc's --coverage option, we can perform automatic coverage data
collection for the test suite.

Add a new Makefile target 'coverage' that scraps all previous coverage
results, recompiles git with the required compiler/linker flags (in
addition to any flags you specify manually), then runs the test suite
and compiles a report.

The compilation must be done with all optimizations disabled, since
inlined functions (and for line-by-line coverage, also optimized
branches/loops) break coverage tracking.

The tests are run serially (with -j1).  The coverage code should
theoretically allow concurrent access to its data files, but the
author saw random test failures.  Obviously this could be improved.

The report currently consists of a list of functions that were never
executed during the tests, which is written to
'coverage-untested-functions'.  Once this list becomes reasonably
short, we would also want to look at branches that were never taken.

Currently only toplevel *.c files are considered.  It would be nice to
at least include xdiff, but --coverage did not save data to
subdirectories on the system used to write this (gcc 4.3.2).

0c0ead7e79 Makefile: fix misdetection of relative pathnames
The installation rules wanted to differentiate between a template_dir that
is given as an absolute path (e.g. /usr/share/git-core/templates) and a
relative one (e.g. share/git-core/templates) but it was done by checking
if $(abspath $(template_dir)) and $(template_dir) yield the same string.

This was wrong in at least two ways.

 * The user can give template_dir with a trailing slash from the command
   line to invoke make or from the included config.mak.  A directory path
   ought to mean the same thing with or without such a trailing slash but
   use of $(abspath) means an absolute path with a trailing slash fails
   the test.

 * Versions of GNU make older than 3.81 do not have $(abspath) to begin
   with.

This changes the detection logic to see if the given path begins with a
slash.

35fb0e8633 Compute prefix at runtime if RUNTIME_PREFIX is set
This commit adds support for relocatable binaries (called
RUNTIME_PREFIX).  Such binaries can be moved together with the
system configuration files to a different directory, as long as the
relative paths from the binary to the configuration files is
preserved.  This functionality is essential on Windows where we
deliver git binaries with an installer that allows to freely choose
the installation location.

If RUNTIME_PREFIX is unset we use the static prefix.  This will be
the default on Unix.  Thus, the behavior on Unix will remain
identical to the old implementation, which used to add the prefix
in the Makefile.

If RUNTIME_PREFIX is set the prefix is computed from the location
of the executable.  In this case, system_path() tries to strip
known directories that executables can be located in from the path
of the executable.  If the path is successfully stripped it is used
as the prefix.  For example, if the executable is
"/msysgit/bin/git" and BINDIR is "bin", then the prefix computed is
"/msysgit".

If the runtime prefix computation fails, we fall back to the static
prefix specified in the makefile.  This can be the case if the
executable is not installed at a known location.  Note that our
test system sets GIT_CONFIG_NOSYSTEM to tell git to ignore global
configuration files during testing.  Hence testing does not trigger
the fall back.

Note that RUNTIME_PREFIX only works on Windows, though adding
support on Unix should not be too hard.  The implementation
requires argv0_path to be set to an absolute path.  argv0_path must
point to the directory of the executable.  We use assert() to
verify this in debug builds.  On Windows, the wrapper for main()
(see compat/mingw.h) guarantees that argv0_path is correctly
initialized.  On Unix, further work is required before
RUNTIME_PREFIX can be enabled.

026fa0d5ad Move computation of absolute paths from Makefile to runtime (in preparation for RUNTIME_PREFIX)
This commit prepares the Makefile for relocatable binaries (called
RUNTIME_PREFIX).  Such binaries will be able to be moved together
with the system configuration files to a different directory,
requiring to compute the prefix at runtime.

In a first step, we make all paths relative in the Makefile and
teach system_path() to add the prefix instead.  We used to compute
absolute paths in the Makefile and passed them to C as defines.  We
now pass relative paths to C and call system_path() to add the
prefix at runtime.

4a16d07272 chain kill signals for cleanup functions
If a piece of code wanted to do some cleanup before exiting
(e.g., cleaning up a lockfile or a tempfile), our usual
strategy was to install a signal handler that did something
like this:

  do_cleanup(); /* actual work */
  signal(signo, SIG_DFL); /* restore previous behavior */
  raise(signo); /* deliver signal, killing ourselves */

For a single handler, this works fine. However, if we want
to clean up two _different_ things, we run into a problem.
The most recently installed handler will run, but when it
removes itself as a handler, it doesn't put back the first
handler.

This patch introduces sigchain, a tiny library for handling
a stack of signal handlers. You sigchain_push each handler,
and use sigchain_pop to restore whoever was before you in
the stack.

b56c79ccea Makefile: use shell for-loop rather than Make's foreach loop during install
The install target uses a foreach loop to generate a single long shell
command line to handle installation of the built-in git commands.  The
maximum length of the argument list varies by platform, and this use of
foreach quickly grows the length of the argument list.  Current git can
exceed the default maximum argument list length on IRIX 6.5 of 20480
depending on the installation path.

Rather than using make's foreach loop to pre-generate the shell command
line, use a shell for-loop and allow the shell to iterate through each of
the built-in commands.

b4285c71bc Add ctype test
Manipulating the character class table in ctype.c by hand is error prone.
To ensure that typos are found quickly, add a test program and script.

test-ctype checks the output of the character class macros isspace() et.
al. by applying them on all possible char values and consulting a list of
all characters in the particular class.  It doesn't check tolower() and
toupper(); this could be added later.

879ef2485d Introduce commit notes
Commit notes are blobs which are shown together with the commit
message.  These blobs are taken from the notes ref, which you can
configure by the config variable core.notesRef, which in turn can
be overridden by the environment variable GIT_NOTES_REF.

The notes ref is a branch which contains "files" whose names are
the names of the corresponding commits (i.e. the SHA-1).

The rationale for putting this information into a ref is this: we
want to be able to fetch and possibly union-merge the notes,
maybe even look at the date when a note was introduced, and we
want to store them efficiently together with the other objects.

be58e70dba diff: unify external diff and funcname parsing code
Both sets of code assume that one specifies a diff profile
as a gitattribute via the "diff=foo" attribute. They then
pull information about that profile from the config as
diff.foo.*.

The code for each is currently completely separate from the
other, which has several disadvantages:

  - there is duplication as we maintain code to create and
    search the separate lists of external drivers and
    funcname patterns

  - it is difficult to add new profile options, since it is
    unclear where they should go

  - the code is difficult to follow, as we rely on the
    "check if this file is binary" code to find the funcname
    pattern as a side effect. This is the first step in
    refactoring the binary-checking code.

This patch factors out these diff profiles into "userdiff"
drivers. A file with "diff=foo" uses the "foo" driver, which
is specified by a single struct.

Note that one major difference between the two pieces of
code is that the funcname patterns are always loaded,
whereas external drivers are loaded only for the "git diff"
porcelain; the new code takes care to retain that situation.

0e214af9c3 Makefile: do not set NEEDS_LIBICONV for Solaris 8
This breaks my build on Solaris 8, as there is no separate
libiconv.

The history of this line is somewhat convoluted. In 2fd955c
(in November 2005), NEEDS_LIBICONV was turned on for all
Solaris builds, claiming to "fix an error in Solaris 10 by
setting NEEDS_LIBICONV".

Later, e15f545 (in February of 2006) claimed that "Solaris
9+ don't need iconv", and moved NEEDS_LIBICONV into a
section for Solaris 8.

Furthermore, Brandon Casey claims in

<5A1KxlhmUIHe8iXPxnXYuNXsq0Yjlbwkz2eBin3z7ELuL9nK-4tSpw@cipher.nrlssc.navy.mil>

that he does not set NEEDS_LIBICONV for Solaris 7.

So either one of those commits is totally wrong, or there is
some other magic going on where some Solaris installs need
it and others don't.

Given Brandon's statement and my problems on Solaris 8 with
NEEDS_LIBICONV, I am inclined to think the first commit was
bogus, and that NEEDS_LIBICONV shouldn't be set for Solaris
at all by default. If somebody wants to use iconv and has
installed it manually, they can set it in their config.mak.

adbc0b6b6e cygwin: Use native Win32 API for stat
lstat/stat functions in Cygwin are very slow, because they try to emulate
some *nix things that Git does not actually need. This patch adds Win32
specific implementation of these functions for Cygwin.

This implementation handles most situation directly but in some rare cases
it falls back on the implementation provided for Cygwin. This is necessary
for two reasons:

- Cygwin has its own file hierarchy, so absolute paths used in Cygwin is
  not suitable to be used Win32 API. cygwin_conv_to_win32_path can not be
  used because it automatically dereference Cygwin symbol links, also it
  causes extra syscall. Fortunately Git rarely use absolute paths, so we
  always use Cygwin implementation for absolute paths.

- Support of symbol links. Cygwin stores symbol links as ordinary using
  one of two possible formats. Therefore, the fast implementation falls
  back to Cygwin functions if it detects potential use of symbol links.

The speed of this implementation should be the same as mingw_lstat for
common cases, but it is considerable slower when the specified file name
does not exist.

Despite all efforts to make the fast implementation as robust as possible,
it may not work well for some very rare situations. I am aware only one
situation: use Cygwin mount to bind unrelated paths inside repository
together.  Therefore, the core.ignoreCygwinFSTricks configuration option is
provided, which controls whether native or Cygwin version of stat is used.

This is documented in INSTALL now, together with corrections: Before,
instructions in INSTALL would build man+html but install man only. Now
the instructions build and install both, and new and pre-existing
targets are explained.

Note that build targets "doc" and "man" correspond to install targets
"install-doc install-html" and "install-doc" respectively. This
inconsistency is not changed, in order to keep everyone's build scripts

To fix this, we use the GNU regex library which is already present in

to the COMPAT_CFLAGS variable causes a conflict between the system
fnmatch.h and the one present in compat/.  To remedy this, move the
regex and fnmatch functionality to their own subdirectories in compat/
so they can be included seperately.

e705d757bd Windows: git-shell can be compiled again
The reason that git-shell was excluded from the Windows build was that
our compatibility layer needed stuff that was removed when we tried to
link less of the git library into git-shell. Since 4cfc24a (shell: do
not play duplicated definition games to shrink the executable,
2008-08-19) the complete library is linked again, so we can build
git-shell on Windows as well. (This fixes 'make install', which depends
on that git-shell is always built.)

8af84dadb1 git wrapper: DWIM mistyped commands
This patch introduces a modified Damerau-Levenshtein algorithm into
Git's code base, and uses it with the following penalties to show some
similar commands when an unknown command was encountered:

	swap = 0, insertion = 1, substitution = 2, deletion = 4

A typical output would now look like this:

	$ git sm
	git: 'sm' is not a git-command. See 'git --help'.

	Did you mean one of these?
		am
		rm

The cut-off is at similarity rating 6, which was empirically determined
to give sensible results.

As a convenience, if there is only one candidate, Git continues under
the assumption that the user mistyped it.  Example:

	$ git reabse
	WARNING: You called a Git program named 'reabse', which does
	not exist.
	Continuing under the assumption that you meant 'rebase'

3e073dc561 Makefile: always provide a fallback when hardlinks fail
We make hardlinks from "git" to "git-<cmd>" built-ins and have been
careful to avoid cross-device links when linking "git-<cmd>" to
gitexecdir.

However, we were not prepared to deal with a build directory that is
incapable of making hard links within itself. This patch corrects it.

Instead of temporarily linking "git" to gitexecdir, directly link "git-
add", falling back to "cp". Try hardlinking that as "git-<cmd>", falling
back to symlinks or "cp" on error.

While at it, avoid 100+ error messages from hardlink failures when we are
going to fall back to symlinks or "cp" by redirecting the standard error
to /dev/null.

$(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.

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

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

5b2fd95606 rerere: Separate libgit and builtin functions
This patch moves rerere()-related functions into a newly created
rerere.c file.
The setup_rerere() function is needed by both rerere() and cmd_rerere(),
so this function is moved to rerere.c and declared non-static (and "extern")
in newly created rerere.h file.

51add76e92 Retire 'stupid' merge strategy
As pointed out by Linus, this strategy tries to take the best merge
base, but 'recursive' just does it better. If one needs something more
than 'resolve' then he/she should really use 'recursive' and not
'stupid'.

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:

Before:
   text    data     bss     dec     hex filename
 143915    1348   93168  238431   3a35f git-shell

0b50b860a5 When installing, be prepared that template_dir may be relative.
Since the Makefile in the template/ subdirectory is only used to install
the templates, we do not simply pass down the setting of template_dir
when it is relative, but construct the intended destination in a new
variable: A relative template_dir is relative to gitexecdir.

98db51e624 Keep some git-* programs in $(bindir)
Otherwise remote executions directly over ssh won't find them as they used
to.  --upload-pack and --receive-pack options _could_ be used on the
client side, but things should keep working out-of-box for older clients.

Later versions of clients (fetch-pack and send-pack) probably could start
asking for these programs with dashless form, but that is a different
topic.

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.

Dmitry Kakurin pointed out that access(..., X_OK) would always fails on
Vista and suggested the -D__USE_MINGW_ACCESS workaround.
