The commit 2f8952250a ("regex: add regexec_buf() that can work on a
non NUL-terminated string", 2016-09-21) changed description of
NO_REGEX build config variable to be more neutral, and actually say
that it is about support for REG_STARTEND.  Change description in
configure.ac to match.

Change also the test message and variable name to match.  The test
just checks that REG_STARTEND is #defined.

Existing autoconf generated test for the need to link with pthread
library did not check all the functions from pthread libraries;

We need to test linkage of pthread_create and pthread_join,
as pthread_mutex_* and pthread_key_* functions do not need
extra linkage under FreeBSD 10.3, leading to a false-positive
of the empty case.

924b7eb1c9 ./configure.ac: detect SSL in libcurl using curl-config
The API of libcurl does not mention Curl_ssl_init() and when curl is
built with -flto, the Curl_ssl_init symbol is not exported.

https://curl.haxx.se/libcurl/using/ suggests calling

  curl-config --feature | grep SSL

to see, if the installed curl has SSL support.  Another approach
would be calling curl_version_info and checking the returned struct.

This patch removes the check for the Curl_ssl_init exported symbol
from libcurl and uses curl-config to detect SSL support in libcurl.

Recent versions of GNU grep is pickier than before to decide if a
file is "binary" and refuse to give line-oriented hits when we
expect it to, unless explicitly told with "-a" option.  As our
scripted Porcelains use sane_grep wrapper for line-oriented data,
even when the line may contain non-ASCII payload we took from
end-user data, use "grep -a" to implement sane_grep wrapper when
using an implementation of "grep" that takes the "-a" option.

7e91e8d73a configure.ac: detect ssl need with libcurl
When libcurl has been statically compiled with openssl support they both
need to be linked in everytime libcurl is used.

During configuration this can be detected by looking for Curl_ssl_init
function symbol in libcurl, which will only be present if libcurl has been
compiled statically built with openssl.

configure.ac checks for Curl_ssl_init function in libcurl and if such function
exists; it sets NEEDS_SSL_WITH_CURL that is used by the Makefile to include
-lssl alongside with -lcurl.

d543d9c0f4 compat: convert modes to use portable file type values
This adds simple wrapper functions around calls to stat(), fstat(),
and lstat() that translate the operating system's native file type
bits to those used by most operating systems.  It also rewrites the
S_IF* macros to the common values, so all file type processing is
performed using the translated modes.  This makes projects portable
across operating systems that use different file type definitions.

Only the file type bits may be affected by these compatibility
functions; the file permission bits are assumed to be 07777 and are
passed through unchanged.

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.

file since the early days back when we used MAXPATHLEN (which we no

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.

9979a507c5 configure.ac: Add missing comma to CC_LD_DYNPATH
40bfbde ("build: don't duplicate substitution of make variables",
2012-09-11) by mistake removed a necessary comma at the end of
"CC_LD_DYNPATH=-Wl,rpath," in line 414.

When executing "./configure --with-zlib=PATH", this resulted in

      [...]
      CC xdiff/xhistogram.o
      AR xdiff/lib.a
      LINK git-credential-store
  /usr/bin/ld: bad -rpath option
  collect2: ld returned 1 exit status
  make: *** [git-credential-store] Error 1
  $

during make.

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
obscured the code flow.

3a34c2bf62 build: improve GIT_CONF_SUBST signature
Now, in configure.ac, a call like:

    GIT_CONF_SUBST([FOO])

will be considered equivalent to:

    GIT_CONF_SUBST([FOO], [$FOO])

This is mostly a preparatory refactoring in view of future changes.
No semantic change to the generated configure or config.mak.auto is
intended.

8242ff470f build: reconfigure automatically if configure.ac changes
This provides a reduced but still useful sibling of the Automake's
"automatic Makefile rebuild" feature.  It's important to note that
we take care to enable the new rules only if the tree that has already
be configured with './configure', so that users relying on manual
configuration won't be negatively impacted.

ac5fc1c57f autoconf: use AC_CONFIG_COMMANDS instead of ad-hoc 'config.mak.append'
This will allow "./config.status --recheck; ./config.status" to work
correctly as a mean of reconfiguring the tree with the same configure
argument used in the previous "./configure" invocation.
