Your build platform may support hardlinks but you may prefer not to use
them, e.g. when installing to DESTDIR to make a tarball and untarring on
a filesystem that has poor support for hardlinks.
The Makefile in git-gui project may need to learn to honor the same
setting; it unconditionally creates git-citool by hardlinking git-gui.

when installing git-foo builtins and favor symblic links or copies for

Document the default pager and editor chosen at compile time in the

git will fall back to when EDITOR, VISUAL, and PAGER are unset can
find the answer quickly.
In builds leaving those settings uncustomized, this patch makes the
manpage continue to say "usually vi" and "usually less" so the
formatted documentation is usable for a wide audience including users
of custom builds that change those settings. If you would like your
copy of the docs to be less noncommittal, you will need to set
DEFAULT_PAGER=less and DEFAULT_EDITOR=vi explicitly.

Redo the hashing loop in xdl_hash_record in a way that loads an entire
'long' at a time, using masking tricks to see when and where we found
the terminating '\n'.
I stole inspiration and code from the posts by Linus Torvalds around
https://lkml.org/lkml/2012/3/2/452https://lkml.org/lkml/2012/3/5/6
His method reads the buffers in sizeof(long) increments, and may thus
overrun it by at most sizeof(long)-1 bytes before it sees the final
newline (or hits the buffer length check). I considered padding out
all buffers by a suitable amount to "catch" the overrun, but
* this does not work for mmap()'d buffers: if you map 4096+8 bytes
from a 4096 byte file, accessing the last 8 bytes results in a
SIGBUS on my machine; and
* it would also be extremely ugly because it intrudes deep into the
unpacking machinery.
So I adapted it to not read beyond the buffer at all. Instead, it
reads the final partial word byte-by-byte and strings it together.
Then it can use the same logic as before to finish the hashing.
So far we enable this only on x86_64, where it provides nice speedup
for diff-related work:
Test origin/next tr/xdiff-fast-hash
-----------------------------------------------------------------------------
4000.1: log -3000 (baseline) 0.07(0.05+0.02) 0.08(0.06+0.02) +14.3%

During the testing of the 1.7.10 rc series on Solaris for OpenCSW, it
was discovered that t7006-pager was failing due to finding a bad "sh"
in PATH after a call to execvp("sh", ...). This call was setup by
run_command.c:prepare_shell_cmd.
The PATH in use at the time saw /opt/csw/bin given precedence to
traditional Solaris paths such as /usr/bin and /usr/xpg4/bin. A
package named schilyutils (Joerg Schilling's utilities) was installed
on the build system and it delivered a modified version of the
traditional Solaris /usr/bin/sh as /opt/csw/bin/sh. This version of
sh suffers from many of the same problems as /usr/bin/sh.
The command-specific pager test failed due to the broken "sh" handling
^ as a pipe character. It tried to fork two processes when it
encountered "sed s/^/foo:/" as the pager command. This problem was
entirely dependent on the PATH of the user at runtime.
Possible fixes for this issue are:
1. Use the standard system() or popen() which both launch a POSIX
shell on Solaris as long as _POSIX_SOURCE is defined.
2. The git wrapper could prepend SANE_TOOL_PATH to PATH thus forcing
all unqualified commands run to use the known good tools on the
system.
3. The run_command.c:prepare_shell_command() could use the same
SHELL_PATH that is in the #! line of all all scripts and not rely
on PATH to find the sh to run.
Option 1 would preclude opening a bidirectional pipe to a filter
script and would also break git for Windows as cmd.exe is spawned from
system() (cf. v1.7.5-rc0~144^2, "alias: use run_command api to execute
aliases, 2011-01-07).
Option 2 is not friendly to users as it would negate their ability to
use tools of their choice in many cases. Alternately, injecting
SANE_TOOL_PATH such that it takes precedence over /bin and /usr/bin
(and anything with lower precedence than those paths) as
git-sh-setup.sh does would not solve the problem either as the user
environment could still allow a bad sh to be found. (Many OpenCSW
users will have /opt/csw/bin leading their PATH and some subset would
have schilyutils installed.)
Option 3 allows us to use a known good shell while still honouring the
users' PATH for the utilities being run. Thus, it solves the problem
while not negatively impacting either users or git's ability to run
external commands in convenient ways. Essentially, the shell is a
special case of tool that should not rely on SANE_TOOL_PATH and must
be called explicitly.
With this patch applied, any code path leading to
run_command.c:prepare_shell_cmd can count on using the same sane shell
that all shell scripts in the git suite use. Both the build system
and run_command.c will default this shell to /bin/sh unless
overridden.

This introduces a performance testing framework under t/perf/. It
tries to be as close to the test-lib.sh infrastructure as possible,
and thus should be easy to get used to for git developers.
The following points were considered for the implementation:
1. You usually want to compare arbitrary revisions/build trees against
each other. They may not have the performance test under
consideration, or even the perf-lib.sh infrastructure.
To cope with this, the 'run' script lets you specify arbitrary
build dirs and revisions. It even automatically builds the revisions
if it doesn't have them at hand yet.
2. Usually you would not want to run all tests. It would take too
long anyway. The 'run' script lets you specify which tests to run;
or you can also do it manually. There is a Makefile for
discoverability and 'make clean', but it is not meant for
real-world use.
3. Creating test repos from scratch in every test is extremely
time-consuming, and shipping or downloading such large/weird repos
is out of the question.
We leave this decision to the user. Two different sizes of test
repos can be configured, and the scripts just copy one or more of
those (using hardlinks for the object store). By default it tries
to use the build tree's git.git repository.
This is fairly fast and versatile. Using a copy instead of a clone
preserves many properties that the user may want to test for, such
as lots of loose objects, unpacked refs, etc.

Ever since the very first commit to git.git we've been setting CC to
"gcc". Presumably this is behavior that Linus copied from the Linux
Makefile.
However unlike Linux Git is written in ANSI C and supports a multitude
of compilers, including Clang, Sun Studio, xlc etc. On my Linux box
"cc" is a symlink to clang, and on a Solaris box I have access to "cc"
is Sun Studio's CC.
Both of these are perfectly capable of compiling Git, and it's
annoying to have to specify CC=cc on the command-line when compiling
Git when that's the default behavior of most other portable programs.
So change the default to "cc". Users who want to compile with GCC can
still add "CC=gcc" to the make(1) command-line, but those users who
don't have GCC as their "cc" will see expected behavior, and as a
bonus we'll be more likely to smoke out new compilation warnings from
our distributors since they'll me using a more varied set of compilers
by default.

There was a number of problems I ran into when trying the
profile-directed optimizations added by Andi Kleen in git commit
7ddc2710b9. (This was using gcc 4.4 found on many enterprise
distros.)
1) The -fprofile-generate and -fprofile-use commands are incompatible
with ccache; the code ends up looking in the wrong place for the gcda
files based on the ccache object names.
2) If the makefile notices that CFLAGS are different, it will rebuild
all of the binaries. Hence the recipe originally specified by the
INSTALL file ("make profile-all" followed by "make install") doesn't
work. It will appear to work, but the binaries will end up getting
built with no optimization.
This patch fixes this by using an explicit set of options passed via
the PROFILE variable then using this to directly manipulate CFLAGS and
EXTLIBS.
The developer can run "make PROFILE=BUILD all ; sudo make
PROFILE=BUILD install" automatically run a two-pass build with the
test suite run in between as the sample workload for the purpose of
recording profiling information to do the profile-directed
optimization.
Alternatively, the profiling version of binaries can be built using:
make PROFILE=GEN PROFILE_DIR=/var/cache/profile all
make PROFILE=GEN install
and then after git has been used for a while, the optimized version of
the binary can be built as follows:
make PROFILE=USE PROFILE_DIR=/var/cache/profile all
make PROFILE=USE install

When we need to prompt the user for input interactively, we
want to access their terminal directly. We can't rely on
stdio because it may be connected to pipes or files, rather
than the terminal. Instead, we use "getpass()", because it
abstracts the idea of prompting and reading from the
terminal. However, it has some problems:
1. It never echoes the typed characters, which makes it OK
for passwords but annoying for other input (like usernames).
2. Some implementations of getpass() have an extremely
small input buffer (e.g., Solaris 8 is reported to
support only 8 characters).
3. Some implementations of getpass() will fall back to
reading from stdin (e.g., glibc). We explicitly don't
want this, because our stdin may be connected to a pipe
speaking a particular protocol, and reading will
disrupt the protocol flow (e.g., the remote-curl

4. Some implementations of getpass() turn off signals, so
that hitting "^C" on the terminal does not break out of
the password prompt. This can be a mild annoyance.
Instead, let's provide an abstract "git_terminal_prompt"
function that addresses these concerns. This patch includes
an implementation based on /dev/tty, enabled by setting
HAVE_DEV_TTY. The fallback is to use getpass() as before.

This is like "cache", except that we actually put the
credentials on disk. This can be terribly insecure, of
course, but we do what we can to protect them by filesystem
permissions, and we warn the user in the documentation.
This is not unlike using .netrc to store entries, but it's a
little more user-friendly. Instead of putting credentials in
place ahead of time, we transparently store them after
prompting the user for them once.

If you access repositories over smart-http using http
authentication, then it can be annoying to have git ask you
for your password repeatedly. We cache credentials in
memory, of course, but git is composed of many small
programs. Having to input your password for each one can be
frustrating.
This patch introduces a credential helper that will cache
passwords in memory for a short period of time.

Signed-off-by: Junio C Hamano <gitster@pobox.com>
There are a few places in git that need to get a username
and password credential from the user; the most notable one
is HTTP authentication for smart-http pushing.
Right now the only choices for providing credentials are to
put them plaintext into your ~/.netrc, or to have git prompt
you (either on the terminal or via an askpass program). The
former is not very secure, and the latter is not very
convenient.
Unfortunately, there is no "always best" solution for
password management. The details will depend on the tradeoff
you want between security and convenience, as well as how
git can integrate with other security systems (e.g., many
operating systems provide a keychain or password wallet for
single sign-on).
This patch provides an abstract notion of credentials as a
data item, and provides three basic operations:
- fill (i.e., acquire from external storage or from the
user)
- approve (mark a credential as "working" for further
storage)
- reject (mark a credential as "not working", so it can
be removed from storage)
These operations can be backed by external helper processes
that interact with system- or user-specific secure storage.

Change the skeleton implementation of i18n in Git to one that can show
localized strings to users for our C, Shell and Perl programs using
either GNU libintl or the Solaris gettext implementation.
This new internationalization support is enabled by default. If
gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, Git falls back on its current behavior of
showing interface messages in English. When using the autoconf script
we'll auto-detect if the gettext libraries are installed and act
appropriately.
This change is somewhat large because as well as adding a C, Shell and
Perl i18n interface we're adding a lot of tests for them, and for
those tests to work we need a skeleton PO file to actually test
translations. A minimal Icelandic translation is included for this
purpose. Icelandic includes multi-byte characters which makes it easy
to test various edge cases, and it's a language I happen to
understand.
The rest of the commit message goes into detail about various
sub-parts of this commit.
= Installation
Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git itself.
= Perl
Perl code that's to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by default.
Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.
Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.
I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.
See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for
a further elaboration on this topic.
= Shell
Shell code that's to be localized should use the git-sh-i18n
library. It's basically just a wrapper for the system's gettext.sh.
If gettext.sh isn't available we'll fall back on gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.
If neither are present we'll use a dumb printf(1) fall-through
wrapper.
= About libcharset.h and langinfo.h
We use libcharset to query the character set of the current locale if
it's available. I.e. we'll use it instead of nl_langinfo if
HAVE_LIBCHARSET_H is set.
The GNU gettext manual recommends using langinfo.h's
nl_langinfo(CODESET) to acquire the current character set, but on
systems that have libcharset.h's locale_charset() using the latter is
either saner, or the only option on those systems.
GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either,
but MinGW and some others need to use libcharset.h's locale_charset()
instead.

Now that the COMPUTE_HEADER_DEPENDENCIES feature is turned on
automatically for compilers that support it (see v1.7.8-rc0~142^2~1,
2011-08-18), there is no easy way to force it off. For example,
setting COMPUTE_HEADER_DEPENDENCIES to the empty string in config.mak
just tells the makefile to treat it as undefined and run a test
command to see if the -MMD option is supported.
So allow setting COMPUTE_HEADER_DEPENDENCIES=no to explicitly force
the feature off. The new semantics:
- "yes" means to explicitly enable the feature
- "no" means to disable it
- "auto" means to autodetect
The default is still "auto". Any value other than these three will
cause the build to error out with a descriptive message so typos and
stale settings in config.mak don't result in mysterious behavior.
Makefile:1278: *** please set COMPUTE_HEADER_DEPENDENCIES to
yes, no, or auto (not "1"). Stop.
So now when someone using a compiler without -MMD support reports
trouble building git, you can reproduce it by running "make
COMPUTE_HEADER_DEPENDENCIES=no".

This mostly moves existing code from builtin/tag.c (for signing)
and builtin/verify-tag.c (for verifying) to a new gpg-interface.c
file to provide a more generic library interface.
- sign_buffer() takes a payload strbuf, a signature strbuf, and a signing
key, runs "gpg" to produce a detached signature for the payload, and
appends it to the signature strbuf. The contents of a signed tag that
concatenates the payload and the detached signature can be produced by
giving the same strbuf as payload and signature strbuf.
- verify_signed_buffer() takes a payload and a detached signature as
<ptr, len> pairs, and runs "gpg --verify" to see if the payload matches
the signature. It can optionally capture the output from GPG to allow
the callers to pretty-print it in a way more suitable for their
contexts.
"verify-tag" (aka "tag -v") used to save the whole tag contents as if it
is a detached signature, and fed gpg the payload part of the tag. It
relied on gpg to fail when the given tag is not signed but just is
annotated. The updated run_gpg_verify() function detects the lack of
detached signature in the input, and errors out without bothering "gpg".

Ever since mergetool--lib was split into multiple files in
v1.7.7-rc0~3^2~1 (2011-08-18), the Makefile takes care to reset umask
and use tar --no-owner when installing merge tool definitions to
$(gitexecdir)/mergetools/. Unfortunately it does not take into
account the possibility that the permission bits of the files being
copied might already be wrong.
Rather than fixing the "tar" incantation and making it even more
complicated, let's just use the "install" utility. This only means
losing the ability to install executables and subdirectories of
mergetools/, which wasn't used.

The g+s bit on directories to make group ownership inherited is a
SysVism --- BSD and most of its descendants do not need it since they
do the sane thing by default without g+s. In fact, on some
filesystems (but not all --- tmpfs works this way but UFS does not),
the kernel of FreeBSD does not even allow non-root users to set setgid
bit on directories and produces errors when one tries:
$ git init --shared dir
fatal: Could not make /tmp/dir/.git/refs writable by group
Since the setgid bit would only mean "do what you were going to do
already", it's better to avoid setting it. Accordingly, ever since
v1.5.5-rc0~59^2 (Do not use GUID on dir in git init --share=all on
FreeBSD, 2008-03-05), git on true FreeBSD has done exactly that. Set
DIR_HAS_BSD_GROUP_SEMANTICS in the makefile for GNU/kFreeBSD, too, so
machines that use glibc with the kernel of FreeBSD get the same fix.
This fixes t0001-init.sh and t1301-shared-repo.sh on GNU/kFreeBSD
when running tests with --root pointing to a directory that uses
tmpfs.

The submodule code recently grew generic code to build a
dynamic argv array. Many other parts of the code can reuse
this, too, so let's make it generically available.
There are two enhancements not found in the original code:
1. We now handle the NULL-termination invariant properly,
even when no strings have been pushed (before, you
could have an empty, NULL argv). This was not a problem
for the submodule code, which always pushed at least
one argument, but was not sufficiently safe for
generic code.
2. There is a formatted variant of the "push" function.
This is a convenience function which was not needed by
the submodule code, but will make it easier to port
other users to the new code.

Add a gcc profile feedback build option "profile-all" to the main
Makefile. It simply runs the test suite to generate feedback data and the
recompiles the main executables with that. The basic structure is similar
to the existing gcov code.
gcc is often able to generate better code with profile feedback data. The
training load also doesn't need to be too similar to the actual load, it
still gives benefits.
The test suite run is unfortunately quite long. It would be good to find a
suitable subset that runs faster and still gives reasonable feedback.
For now the test suite runs single threaded (I had some trouble running
the test suite with -jX)
I tested it with git gc and git blame kernel/sched.c on a Linux kernel
tree. For gc I get about 2.7% improvement in wall clock time by using the
feedback build, for blame about 2.4%. That's not gigantic, but not shabby
either for a very small patch.
If anyone has any favourite CPU intensive git benchmarks feel free to try
them too.

Given an object name, use open_istream() to get a git_istream handle
that you can read_istream() from as if you are using read(2) to read
the contents of the object, and close it with close_istream() when
you are done.
Currently, we do not do anything fancy--it just calls read_sha1_file()
and keeps the contents in memory as a whole, and carve it out as you
request with read_istream().

Change the "pot" target to also extract strings from our $(SCRIPT_SH)
files with xgettext(1).
Note that due to Jonathan Nieder's trick of doing "mv $@+ $@" at the
end of the target the "pot" target will now warn:
$ make pot
XGETTEXT po/git.pot
po/git.pot+: warning: Charset "CHARSET" is not a portable encoding name.
Message conversion to user's charset might not work.
This warnings is emitted because xgettext is writing into a non-*.pot
file, it's harmless however. The content that's written out is
equivalent to what it would be if we were writing directly into an
existing POT file with --join-existing.
As part of this change I've eliminated the && chain between xgettext
calls, this is incompatible with $(QUIET_XGETTEXT), if the && is left
in it'll emit:
/bin/sh: @echo: not found

Add a git-sh-i18n--envsubst program which is a stripped-down version
of the GNU envsubst(1) program that comes with GNU gettext for use in
the eval_gettext() fallback.
We need a C helper program because implementing eval_gettext() purely
in shell turned out to be unworkable. Digging through the Git mailing
list archives will reveal two shell implementations of eval_gettext
that are almost good enough, but fail on an edge case which is tested
for in the tests which are part of this patch.
These are the modifications I made to envsubst.c as I turned it into
sh-i18n--envsubst.c:
* Added our git-compat-util.h header for xrealloc() and friends.
* Removed inclusion of gettext-specific headers.
* Removed most of main() and replaced it with my own. The modified
version only does option parsing for --variables. That's all it
needs.
* Modified error() invocations to use our error() instead of
error(3).
* Replaced the gettext XNMALLOC(n, size) macro with just
xmalloc(n). Since XNMALLOC() only allocated char's.
* Removed the string_list_destroy function. It's redundant (also in
the upstream code).
* Replaced the use of stdbool.h (a C99 header) by doing the following
replacements on the code:
* s/bool/unsigned short int/g
* s/true/1/g
* s/false/0/g

Notice that the prefix specified for the build influenced the definitions
of ETC_GITCONFIG and ETC_GITATTRIBUTES only when it was exactly '/usr'.
Kacper Kornet noticed that this was furthermore only the case when the
build was triggered using 'make prefix=/usr', i.e., the prefix was given
on the command line; it did not work when the prefix was specified in
config.mak because this file is included much later in the Makefile.
To fix this, move the conditional after the inclusion of config.mak.
Additionally, it is desirable to specify the etc directory for a build
(for example, a build with prefix /usr/local may still want to have the
system configuration in /etc/gitconfig). For this purpose, promote the
variable 'sysconfdir' from a helper variable to a configuration
variable. The prefix check that was moved must now be wrapped so that it
does not override sysconfdir setting given in config.mak.

rule to run cgcc.

A delta in the subversion delta (svndiff0) format consists of the
magic bytes SVN\0 followed by a sequence of windows of a certain well
specified format (starting with five integers).
Add an svndiff0_apply function and test-svn-fe -d commandline tool to
parse such a delta in the special case of not including any windows.
Later patches will add features to turn this into a fully functional
delta applier for svn-fe to use to parse the streams produced by
"svnrdump dump" and "svnadmin dump --deltas".
The content of symlinks starts with the word "link " in Subversion's
worldview, so we need to be able to prepend that text to input for the
sake of delta application. So initialization of the input state of
the delta preimage is left to the calling program, giving callers a
chance to seed the buffer with text of their choice.

Each section of a Subversion-format delta only requires examining (and
keeping in random-access memory) a small portion of the preimage. At
any moment, this portion starts at a certain file offset and has a
well-defined length, and as the delta is applied, the portion advances
from the beginning to the end of the preimage. Add a move_window
function to keep track of this view into the preimage.
You can use it like this:
buffer_init(f, NULL);
struct sliding_view window = SLIDING_VIEW_INIT(f);
move_window(&window, 3, 7); /* (1) */
move_window(&window, 5, 5); /* (2) */
move_window(&window, 12, 2); /* (3) */
strbuf_release(&window.buf);
buffer_deinit(f);
The data structure is called sliding_view instead of _window to
prevent confusion with svndiff0 Windows.
In this example, (1) reads 10 bytes and discards the first 3;
(2) discards the first 2, which are not needed any more; and (3) skips
2 bytes and reads 2 new bytes to work with.
When move_window returns, the file position indicator is at position
window->off + window->width and the data from positions window->off to
the current file position are stored in window->buf.
This function performs only sequential access from the input file and
never seeks, so it can be safely used on pipes and sockets.
On end-of-file, move_window silently reads less than the caller
requested. On other errors, it prints a message and returns -1.

Tweak the GETTEXT_POISON facility so it is activated at run time
instead of compile time. If the GIT_GETTEXT_POISON environment
variable is set, _(msg) will result in gibberish as before; but if the
GIT_GETTEXT_POISON variable is not set, it will return the message for
human-readable output. So the behavior of mistranslated and
untranslated git can be compared without rebuilding git in between.
For simplicity we always set the GIT_GETTEXT_POISON variable in tests.
This does not affect builds without the GETTEXT_POISON compile-time
option set, so non-i18n git will not be slowed down.

Add a new GETTEXT_POISON compile-time parameter to make _(msg) always
return gibberish. So now you can run
make GETTEXT_POISON=YesPlease
to get a copy of git that functions correctly (one hopes) but produces
output that is in nobody's native language at all.
This is a debugging aid for people who are working on the i18n part of
the system, to make sure that they are not marking plumbing messages
that should never be translated with _().
As new strings get marked for translation, naturally a number of tests
will be broken in this mode. Tests that depend on output from
Porcelain will need to be marked with the new C_LOCALE_OUTPUT test
prerequisite. Newly failing tests that do not depend on output from
Porcelain would be bugs due to messages that should not have been
marked for translation.
Note that the string we're using ("# GETTEXT POISON #") intentionally
starts the pound sign. Some of Git's tests such as
t3404-rebase-interactive.sh rely on interactive editing with a fake
editor, and will needlessly break if the message doesn't start with
something the interactive editor considers a comment.
A future patch will fix fix the underlying cause of that issue by
adding "#" characters to the commit advice automatically.

The _ function is for translating strings into the user's chosen
language. The N_ macro just marks translatable strings for the
xgettext(1) tool without translating them; it is intended for use in
contexts where a function call cannot be used. So, for example:
fprintf(stderr, _("Expansion of alias '%s' failed; "
"'%s' is not a git command\n"),
cmd, argv[0]);
and
const char *unpack_plumbing_errors[NB_UNPACK_TREES_ERROR_TYPES] = {
/* ERROR_WOULD_OVERWRITE */
N_("Entry '%s' would be overwritten by merge. Cannot merge."),
[...]
Define such _ and N_ in a new gettext.h and include it in cache.h, so
they can be used everywhere. Each just returns its argument for now.
_ is a function rather than a macro like N_ to avoid the temptation to
use _("foo") as a string literal (which would be a compile-time error
once _(s) expands to an expression for the translation of s).

The mingw-runtime implemenation of opendir, readdir and closedir
sets errno to 0 on success, something that POSIX explicitly
forbids. 3ba7a06 ("A loose object is not corrupt if it cannot be
read due to EMFILE") introduce a dependency on this behaviour,
leading to a broken "git clone" on Windows.
compat/mingw.c contains an implementation of readdir, and
compat/msvc.c contains implementations of opendir and closedir.
Move these to compat/win32/dirent.[ch], and change to our own DIR
structure at the same time.
This provides a generic Win32-implementation of opendir, readdir
and closedir which works on both MinGW and MSVC and does not reset
errno, and as a result git clone is working again on Windows.

On some platforms (like Solaris) there is a fnmatch, but it doesn't
support the GNU FNM_CASEFOLD extension that's used by the
jj/icase-directory series' fnmatch_icase wrapper.
Change the Makefile so that it's now possible to set
NO_FNMATCH_CASEFOLD=YesPlease on those systems, and add a configure
probe for it.
Unlike the NO_REGEX check we don't add AC_INCLUDES_DEFAULT to our
headers. This is because on a GNU system the definition of
FNM_CASEFOLD in fnmatch.h is guarded by:
#if !defined _POSIX_C_SOURCE || _POSIX_C_SOURCE < 2 || defined _GNU_SOURCE
One of the headers AC_INCLUDES_DEFAULT includes ends up defining one
of those, so if we'd use it we'd always get
NO_FNMATCH_CASEFOLD=YesPlease on GNU systems, even though they have
FNM_CASEFOLD.
When checking the flags we use:
ifdef NO_FNMATCH
...
else
ifdef NO_FNMATCH_CASEFOLD
...
endif
endif
The "else" so that we don't link against compat/fnmatch/fnmatch.o
twice if both NO_FNMATCH and NO_FNMATCH_CASEFOLD are defined.

Provide macros to generate a type-specific treap implementation and
various functions to operate on it. It uses obj_pool.h to store memory
nodes in a treap. Previously committed nodes are never removed from
the pool; after any *_commit operation, it is assumed (correctly, in
the case of svn-fast-export) that someone else must care about them.
Treaps provide a memory-efficient binary search tree structure.
Insertion/deletion/search are about as about as fast in the average
case as red-black trees and the chances of worst-case behavior are
vanishingly small, thanks to (pseudo-)randomness. The bad worst-case
behavior is a small price to pay, given that treaps are much simpler
to implement.

Add a memory pool library implemented using C macros. The
obj_pool_gen() macro creates a type-specific memory pool.
The memory pool library is distinguished from the existing specialized
allocators in alloc.c by using a contiguous block for all allocations.
This means that on one hand, long-lived pointers have to be written as
offsets, since the base address changes as the pool grows, but on the
other hand, the entire pool can be easily written to the file system.
This could allow the memory pool to persist between runs of an
application.
For the svn importer, such a facility is useful because each svn
revision can copy trees and files from any previous revision. The
relevant information for all revisions has to persist somehow to
support incremental runs.

The manpage was added in 1ed6f2c (Documentation: gitrevisions,
2010-07-05), but since it does not have a corresponding git command,
it needs an exception for check-docs.

To conserve space/improve file caching we try to make hard or symbolic links
from each builtin program to the main git executable rather than having
each be a complete duplicate copy of it. We weren't doing this for the
non-builtin programs though. So, just because we can, and because it's
easy, and for completeness sake, let's do it.

* bc/maint-makefile-fixes:
Makefile: work around ksh's failure to handle missing list argument to for loop
Makefile: remove some unnecessary curly braces
ksh does not like it when the list argument is missing in a 'for' loop.
This can happen when NO_CURL is set which causes REMOTE_CURL_ALIASES to be
unset. In this case, the 'for' loop in the Makefile is expanded to look
like this:
for p in ; do
and ksh complains like this:
/bin/ksh: syntax error at line 15 : `;' unexpected
The existing attempt to work around this issue, introduced by 70b89f87,
tried to protect the 'for' loop by first testing whether REMOTE_CURL_ALIASES
was empty, but this does not work since, as Johannes Sixt explains, "Before
the test for emptyness can happen, the complete statement must be parsed,
but ksh finds a syntax error in the statement and, therefore, cannot even
begin to execute the statement. (ksh doesn't follow POSIX in this regard,
where this would not be a syntax error.)".
Make's $(foreach) function could be used to avoid this shell glitch, but
since it has already caused a problem once before by generating a command
line that exceeded the maximum argument list length on IRIX, let's adopt
Bruce Stephens's suggestion for working around this issue in the same way
the OpenSSL folks have done it. This solution first assigns the contents
of the REMOTE_CURL_ALIASES make variable to a shell variable and then
supplies the shell variable as the list argument in the 'for' loop. This
satisfies ksh and has the expected behavior even if $(REMOTE_CURL_ALIASES)
is empty.
