8eaf517835 Merge branch 'ks/tree-diff-nway'
Instead of running N pair-wise diff-trees when inspecting a
N-parent merge, find the set of paths that were touched by walking
N+1 trees in parallel.  These set of paths can then be turned into
N pair-wise diff-tree results to be processed through rename
detections and such.  And N=2 case nicely degenerates to the usual
2-way diff-tree, which is very nice.

61f76a3612 Portable alloca for Git
In the next patch we'll have to use alloca() for performance reasons,
but since alloca is non-standardized and is not portable, let's have a
trick with compatibility wrappers:

1. at configure time, determine, do we have working alloca() through
   alloca.h, and define

    #define HAVE_ALLOCA_H

   if yes.

2. in code

    #ifdef HAVE_ALLOCA_H
    # include <alloca.h>
    # define xalloca(size)      (alloca(size))
    # define xalloca_free(p)    do {} while(0)
    #else
    # define xalloca(size)      (xmalloc(size))
    # define xalloca_free(p)    (free(p))
    #endif

   and use it like

   func() {
       p = xalloca(size);
       ...

       xalloca_free(p);
   }

This way, for systems, where alloca is available, we'll have optimal
on-stack allocations with fast executions. On the other hand, on
systems, where alloca is not available, this gracefully fallbacks to
xmalloc/free.

Both autoconf and config.mak.uname configurations were updated. For
autoconf, we are not bothering considering cases, when no alloca.h is
available, but alloca() works some other way - its simply alloca.h is
available and works or not, everything else is deep legacy.

For config.mak.uname, I've tried to make my almost-sure guess for where
alloca() is available, but since I only have access to Linux it is the
only change I can be sure about myself, with relevant to other changed
systems people Cc'ed.

NOTE

SunOS and Windows had explicit -DHAVE_ALLOCA_H in their configurations.
I've changed that to now-common HAVE_ALLOCA_H=YesPlease which should be
correct.

62fb6d03da configure.ac: link with -liconv for locale_charset()
On e.g. FreeBSD 10.x, the following situation is common:
- there's iconv implementation in libc, which has no locale_charset()
  function
- there's GNU libiconv installed from Ports Collection

Git build process
- detects that iconv is in libc and thus -liconv is not needed for it
- detects locale_charset in -liconv, but for some reason doesn't add it
  to CHARSET_LIB (as it would do with -lcharset if locale_charset() was
  found there instead of -liconv)
- git doesn't build due to unresolved external locale_charset()

Fix this by adding -liconv to CHARSET_LIB if locale_charset() is
detected in this library.

Since v1.8.4 (about six months ago) wildmatch is used as default
replacement for fnmatch. We have seen only one fix since so wildmatch
probably has done a good job as fnmatch replacement. This concludes
the fnmatch->wildmatch transition by no longer relying on fnmatch.

b2d05e0653 git-compat-util.h: do not #include <sys/param.h> by default
Earlier we allowed platforms that lack <sys/param.h> not to include
the header file from git-compat-util.h; we have included this header
file since the early days back when we used MAXPATHLEN (which we no
longer use) and also depended on it slurping ULONG_MAX (which we get
by including stdint.h or inttypes.h these days).

It turns out that we can compile our modern codebase just file
without including it on many platforms (so far, Fedora, Debian,
Ubuntu, MinGW, Mac OS X, Cygwin, HP-Nonstop, QNX and z/OS are
reported to be OK).

Let's stop including it by default, and on platforms that need it to
be included, leave "make NEEDS_SYS_PARAM_H=YesPlease" as an escape
hatch and ask them to report to us, so that we can find out about
the real dependency and fix it in a more platform agnostic way.

e0a5227930 configure.ac: fix pthreads detection on Mac OS X
The configure script checks whether certain flags are required to use
pthreads. But it did not consider that *none* might be needed (as is the
case on Mac OS X). This lead to configure adding "-mt" to the list of
flags (which does nothing on OS X except producing a warning). This in
turn triggered a compiler warning on every single file.

To solve this, we now first check if pthreads work without extra flags.
This means the check is now order dependant, hence a comment is added
explaining this, and the reasons for it.

Note that it might be possible to write an order independent test, but
it does not seem worth the extra effort required for implementing and
testing such a solution, when this simple solution exists and works.

40bfbde9da build: don't duplicate substitution of make variables
Thanks to our 'GIT_CONF_SUBST' layer in configure.ac, a make variable 'VAR'
can be defined to a value 'VAL' at ./configure runtime in our build system
simply by using "GIT_CONF_SUBST([VAR], [VAL])" in configure.ac, rather than
having both to call "AC_SUBST([VAR], [VAL])" in configure.ac and adding the
'VAR = @VAR@' definition in config.mak.in.  Less duplication, less margin
for error, less possibility of confusion.

While at it, fix some formatting issues in configure.ac that unnecessarily

bf17126211 docs: drop asciidoc7compatible flag
When we made the switch to supporting asciidoc 8 in 4c7100a
(Documentation: adjust to AsciiDoc 8, 2007-06-14), we were
able to leave most of the documentation intact by defining
asciidoc7compatible.

Since commit 6cf378f (docs: stop using asciidoc no-inline-literal,
2012-04-26), we don't support versions of asciidoc older
than 8.4.1, which is when inline literals were introduced.
Therefore there is not much point in keeping our
documentation compatible with asciidoc 7.

So we are now free to drop the asciidoc7compatible flag and
update the documentation itself to assume asciidoc8.
Fortunately, doing the latter is very easy; we weren't using
any of the constructs impacted by asciidoc7compatible, so
there are no changes to make.

The reason is somewhat subtle. The asciidoc7compatible
affects only super/sub-scripts ("^" and "~") and index
terms. We don't use the latter at all. Nor we do we use the
former, but we did have to protect them from accidental
expansion in constructs like "rev^1". However, all of our
uses of "~" and "^" are either in code blocks (which are
rendered literally), or inside backticks. Prior to 6cf378f,
backticks were not inline literals, and needed proper
quoting. But post-6cf378f, we don't have to worry whether we
are using the old or new rules, as those characters are not
interpreted at all in either case.

I verified that the result of "make install-html
install-man" is identical before and after this patch on
asciidoc 8.6.7.

5b2d131419 configure: be more idiomatic
Lots of code in Git's configure.ac doesn't follow the typical formatting,
idioms and best practices for Autoconf input files.  Improve the situation.

There are probably many more similar improvements to be done, but trying
to clump all of them in a single change would make it unreviewable, so we
content ourselves with a partial improvement.

This change is just cosmetic, and should cause no semantic change.

The most relevant of the changes introduced by this patch are:

 - Do not add trailing '\' characters for line continuation where they
   are not truly needed.

 - In several (but not all) macro calls, properly quote the arguments.

 - Few cosmetic changes in spacing and comments.

213639494e configure: allow user to prevent $PATH "sanitization" on Solaris
On a Solaris 10 system with Solaris make installed as '/usr/xpg4/bin/make',
GNU make installed as '/usr/local/bin/make', and with '/usr/local/bin'
appearing in $PATH *before* '/usr/xpg4/bin', I was seeing errors like this
upon invoking "make all":

    Usage : make [ -f makefile ][ -K statefile ]...
    make: Fatal error: Unknown option `-C'

This happenes because the Git's Makefile, when running on Solaris,
automatically "sanitizes" $PATH by prepending '/usr/xpg6/bin' and
'/usr/xpg4/bin' to it in order to avoid using non-POSIX /bin/sh from
being used.  In the setup described above, however, this has an
unintended consequence of forcing the use of Solaris make in recursive
make invocations -- even if the $(MAKE) macro is being correctly used in
them!

When building without using the autoconf machinery, this can be solved
by overriding $(SANE_TOOL_PATH).  Teach the autoconf machinery to also
allow users of ./configure to override it from the command line with a
new --with-sane-tool-path option.

5e9637c629 i18n: add infrastructure for translating Git with gettext
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.

cea13a8d68 Improve test for pthreads flag
When compiling with CC=clang using Clang 1.1 as shipped by Debian
unstable (package version 2.7-3), the -mt flag is sufficient to compile
during the `configure` test. However, building git would then fail at
link time complaining about missing symbols such as `pthread_key_create'
and `pthread_create'.

Work around this issue by adding pthread key creation to the pthreads
configure test source.

28bd70d811 unbreak and eliminate NO_C99_FORMAT
In the spirit of v1.5.0.2~21 (Check for PRIuMAX rather than
NO_C99_FORMAT in fast-import.c, 2007-02-20), use PRIuMAX from
git-compat-util.h on all platforms instead of C99-specific formats
like %zu with dangerous fallbacks to %u or %lu.

So now C99-challenged platforms can build git without provoking
warnings or errors from printf, even if pointers do not have the same
size as an int or long.

The need for a fallback PRIuMAX is detected in git-compat-util.h with
"#ifndef PRIuMAX".  So while at it, simplify the Makefile and configure
script by eliminating the NO_C99_FORMAT knob altogether.

1e58dba142 configure: use AC_LANG_PROGRAM consistently
Avoid warnings from Autoconf 2.68 about missing use of AC_LANG_PROGRAM
and friends.

Quoting autoconf-2.68/NEWS:

  ** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and
     AC_RUN_IFELSE now warn if the first argument failed to use
     AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file
     contents.  A new macro AC_LANG_DEFINES_PROVIDED exists if you have
     a compelling reason why you cannot use AC_LANG_SOURCE but must
     avoid the warning.

The underlying reason for that change is that AC_LANG_{SOURCE,PROGRAM}
take care to supply the previously computed set of #defines (and
include standard headers if so desired) for preprocessed languages
like C and C++.

In some cases, AC_LANG_PROGRAM is already used but not sufficiently
m4-quoted, so we just need to add another set of [quotes] to prevent
the autoconf warning from being triggered bogusly.  Quoting all
arguments (except when calling special macros that need to be expanded
before recursion) is better style, anyway.  These and more rules are
described in detail in 'info Autoconf "Programming in M4"'.

No change in the resulting config.mak.autogen after running
./configure intended.

79c461d5b1 docs: default to more modern toolset
When the ASCIIDOC8 and ASCIIDOC_NO_ROFF knobs were built,
many people were still on asciidoc 7 and using older
versions of docbook-xsl. These days, even the almost
2-year-old Debian stable needs these knobs turned.

So let's turn them by default. The new knobs ASCIIDOC7 and
ASCIIDOC_ROFF can be used to get the old behavior if people
are on older systems.

4de066b6f1 Makefile & configure: add a NO_FNMATCH_CASEFOLD flag
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.

f3f3d9366e Makefile & configure: add a NO_FNMATCH flag
Windows and MinGW both lack fnmatch() in their C library and needed
compat/fnmatch, but they had duplicate code for adding the compat
function, and there was no Makefile flag or configure check for
fnmatch.

Change the Makefile it so that it's now possible to compile the compat
function with a NO_FNMATCH=YesPlease flag, and add a configure probe
for it.

The location of system-wide attributes file is $(prefix)/etc/gitattributes.
The location of the global file can be configured by setting
core.attributesfile.
