In `git version --build-options`, we report also the CPU, but in Git for
Windows we actually cross-compile the 32-bit version in a 64-bit Git for
Windows, so we cannot rely on the auto-detected value.
In 3815f64b0d (mingw: fix CPU reporting in `git version
--build-options`, 2019-02-07), we fixed this by a Windows-only
workaround, making use of magic pre-processor constants, which works in
GCC, but most likely not all C compilers.
As pointed out by Eric Sunshine, there is a better way, anyway: to set
the Makefile variable HOST_CPU explicitly for cross-compiled Git. So
let's do that!
This reverts commit 3815f64b0d partially.

A regression for cygwin users was introduced with commit 05b458c,
"real_path: resolve symlinks by hand".
In the the commit message we read:
The current implementation of real_path uses chdir() in order to resolve
symlinks. Unfortunately this isn't thread-safe as chdir() affects a
process as a whole...
The old (and non-thread-save) OS calls chdir()/pwd() had been
replaced by a string operation.
The cygwin layer "knows" that "C:\cygwin" is an absolute path,
but the new string operation does not.
"git clone <url> C:\cygwin\home\USER\repo" fails like this:
fatal: Invalid path '/home/USER/repo/C:\cygwin\home\USER\repo'
The solution is to implement has_dos_drive_prefix(), skip_dos_drive_prefix()
is_dir_sep(), offset_1st_component() and convert_slashes() for cygwin
in the same way as it is done in 'Git for Windows' in compat/mingw.[ch]
Extract the needed code into compat/win32/path-utils.[ch] and use it
for cygwin as well.

The way -lcurl library gets linked has been simplified by taking
advantage of the fact that we can just ask curl-config command how.
* jk/curl-ldflags:
build: link with curl-defined linker flags
Adjusting the build process to rely more on curl-config to populate
linker flags instead of manually populating flags based off detected
features.
Originally, a configure-invoked build would check for SSL-support in the
target curl library. If enabled, NEEDS_SSL_WITH_CURL would be set and
used in the Makefile to append additional libraries to link against. As
for systems building solely with make, the defines NEEDS_IDN_WITH_CURL
and NEEDS_SSL_WITH_CURL could be set to indirectly enable respective
linker flags. Since both configure.ac and Makefile already rely on
curl-config utility to provide curl-related build information, adjusting
the respective assets to populate required linker flags using the
utility (unless explicitly configured).

Quite some time ago, a last plea to the XP users out there who want to
see Windows XP support in Git for Windows, asking them to get engaged
and help, vanished into the depths of the universe.
We tried for a long time to play nice with the last remaining XP users
who somehow manage to build Git from source, but a recent update of
mingw-w64 (7.0.0.5233.e0c09544 -> 7.0.0.5245.edf66197) finally dropped
the last sign of XP support, and Git for Windows' SDK is no longer able
to build core Git's `master` branch as a consequence. (Git for Windows'
`master` branch already bumped the minimum Windows version to Vista a
while ago, so it is fine.)
It is time to require Windows Vista or later to build Git from source.
This, incidentally, lets us use quite a few nice new APIs.
It also means that we no longer need the inet_pton() and inet_ntop()

"git gc" in a large repository takes a lot of time as it considers
to repack all objects into one pack by default. The command has
been taught to pretend as if the largest existing packfile is
marked with ".keep" so that it is left untouched while objects in
other packs and loose ones are repacked.
* nd/repack-keep-pack:
pack-objects: show some progress when counting kept objects
gc --auto: exclude base pack if not enough mem to "repack -ad"

gc: add gc.bigPackThreshold config
gc: add --keep-largest-pack option
repack: add --keep-pack option
t7700: have closing quote of a test at the beginning of line
pack-objects could be a big memory hog especially on large repos,
everybody knows that. The suggestion to stick a .keep file on the
giant base pack to avoid this problem is also known for a long time.
Recent patches add an option to do just this, but it has to be either
configured or activated manually. This patch lets `git gc --auto`
activate this mode automatically when it thinks `repack -ad` will use
a lot of memory and start affecting the system due to swapping or
flushing OS cache.
gc --auto decides to do this based on an estimation of pack-objects
memory usage, which is quite accurate at least for the heap part, and
whether that fits in half of system memory (the assumption here is for
desktop environment where there are many other applications running).
This mechanism only kicks in if gc.bigBasePackThreshold is not configured.
If it is, it is assumed that the user already knows what they want.

Keep a copy of the `packed-refs` file contents in memory for as long
as a `packed_ref_cache` object is in use:
* If the system allows it, keep the `packed-refs` file mmapped.
* If not (either because the system doesn't support `mmap()` at all,
or because a file that is currently mmapped cannot be replaced via
`rename()`), then make a copy of the file's contents in
heap-allocated space, and keep that around instead.
We base the choice of behavior on a new build-time switch,
`MMAP_PREVENTS_DELETE`. By default, this switch is set for Windows
variants.
After this commit, `MMAP_NONE` and `MMAP_TEMPORARY` are still handled
identically. But the next commit will introduce a difference.

On Cygwin, similar to Windows, "git push //server/share/repository"
ought to mean a repository on a network share that can be accessed
locally, but this did not work correctly due to stripping the double
slashes at the beginning.
This may need to be heavily tested before it gets unleashed to the
wild, as the change is at a fairly low-level code and would affect
not just the code to decide if the push destination is local. There
may be unexpected fallouts in the path normalization.
* tb/push-to-cygwin-unc-path:
cygwin: allow pushing to UNC paths
cygwin can use an UNC path like //server/share/repo
$ cd //server/share/dir
$ mkdir test
$ cd test
$ git init --bare
However, when we try to push from a local Git repository to this repo,
there is a problem: Git converts the leading "//" into a single "/".
As cygwin handles an UNC path so well, Git can support them better:
- Introduce cygwin_offset_1st_component() which keeps the leading "//",
similar to what Git for Windows does.
- Move CYGWIN out of the POSIX in the tests for path normalization in t0060

Amend my change earlier in this series ("grep: add support for the
PCRE v1 JIT API", 2017-04-11) to un-break the build on PCRE v1
versions later than 8.31 compiled without --enable-jit.
As explained in that change and a later compatibility change in this
series ("grep: un-break building with PCRE < 8.32", 2017-05-10) the
pcre_jit_exec() function is a faster path to execute the JIT.
Unfortunately there's no compatibility stub for that function compiled
into the library if pcre_config(PCRE_CONFIG_JIT, &ret) would return 0,
and no macro that can be used to check for it, so the only portable
option to support builds without --enable-jit is via a new
NO_LIBPCRE1_JIT=UnfortunatelyYes Makefile option[1].
Another option would be to make the JIT opt-in via
USE_LIBPCRE1_JIT=YesPlease, after all it's not a default option of
PCRE v1.
I think it makes more sense to make it opt-out since even though it's
not a default option, most packagers of PCRE seem to turn it on by
default, with the notable exception of the MinGW package.
Make the MinGW platform work by default by changing the build defaults
to turn on NO_LIBPCRE1_JIT=UnfortunatelyYes. It is the only platform
that turns on USE_LIBPCRE=YesPlease by default, see commit
df5218b4c3 ("config.mak.uname: support MSys2", 2016-01-13) for that
change.

To test this I added/staged a single file in a gigantic
repository having a 450MB index file. The code in read-cache.c
verifies the header SHA as it reads the index and computes a new
header SHA as it writes out the new index. Therefore, in this test
the SHA code must process 900MB of data. Testing was done on an
Intel I7-4770 CPU @ 3.40GHz (Intel64, Family 6, Model 60) CPU.
The block-sha1 version averaged 5.27 seconds.
The OpenSSL version averaged 4.50 seconds.

The xdiff code hashes every line of both sides of a diff,
and then compares those hashes to find duplicates. The
overall performance depends both on how fast we can compute
the hashes, but also on how many hash collisions we see.
The idea of XDL_FAST_HASH is to speed up the hash
computation. But the generated hashes have worse collision
behavior. This means that in some cases it speeds diffs up
(running "git log -p" on git.git improves by ~8% with it),
but in others it can slow things down. One pathological case
saw over a 100x slowdown[1].
There may be a better hash function that covers both
properties, but in the meantime we are better off with the
original hash. It's slightly slower in the common case, but
it has fewer surprising pathological cases.

MSYS2 emulates pseudo terminals via named pipes, and isatty() returns 0
for such file descriptors. Therefore, some interactive functionality
(such as launching a pager, asking if a failed unlink should be repeated
etc.) doesn't work when run in a terminal emulator that uses MSYS2's
ptys (such as mintty).
However, MSYS2 uses special names for its pty pipes ('msys-*-pty*'),
which allows us to distinguish them from normal piped input / output.
On startup, check if stdin / stdout / stderr are connected to such pipes
using the NtQueryObject API from NTDll.dll. If the names match, adjust

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.

sane_grep: pass "-a" if grep accepts it
Newer versions of GNU grep is reported to be pickier when we feed a
non-ASCII input and break some Porcelain scripts. As we know we do
not feed random binary file to our own sane_grep wrapper, allow us
to always pass "-a" by setting SANE_TEXT_GREP=-a Makefile variable
to work it around.

This solves two problems:
- we now have proper localisation even on Windows
- we sidestep the infamous "BUG: your vsnprintf is broken (returned -1)"
message when running "git init" (which otherwise prevents the entire
test suite from running) because libintl.h overrides vsnprintf() with
libintl_vsnprintf() [*1*]
The latter issue is rather crucial, as *no* test passes in Git for
Windows without this fix.

For a long time, Git for Windows lagged behind Git's 2.x releases because
the Git for Windows developers wanted to let that big jump coincide with
a well-needed jump away from MSys to MSys2.
To understand why this is such a big issue, it needs to be noted that
many parts of Git are not written in portable C, but instead Git relies
on a POSIX shell and Perl to be available.
To support the scripts, Git for Windows has to ship a minimal POSIX
emulation layer with Bash and Perl thrown in, and when the Git for
Windows effort started in August 2007, this developer settled on using
MSys, a stripped down version of Cygwin. Consequently, the original name
of the project was "msysGit" (which, sadly, caused a *lot* of confusion
because few Windows users know about MSys, and even less care).
To compile the C code of Git for Windows, MSys was used, too: it sports
two versions of the GNU C Compiler: one that links implicitly to the
POSIX emulation layer, and another one that targets the plain Win32 API
(with a few convenience functions thrown in). Git for Windows'
executables are built using the latter, and therefore they are really
just Win32 programs. To discern executables requiring the POSIX
emulation layer from the ones that do not, the latter are called MinGW
(Minimal GNU for Windows) when the former are called MSys executables.
This reliance on MSys incurred challenges, too, though: some of our
changes to the MSys runtime -- necessary to support Git for Windows
better -- were not accepted upstream, so we had to maintain our own
fork. Also, the MSys runtime was not developed further to support e.g.
UTF-8 or 64-bit, and apart from lacking a package management system
until much later (when mingw-get was introduced), many packages provided
by the MSys/MinGW project lag behind the respective source code
versions, in particular Bash and OpenSSL. For a while, the Git for
Windows project tried to remedy the situation by trying to build newer
versions of those packages, but the situation quickly became untenable,
especially with problems like the Heartbleed bug requiring swift action
that has nothing to do with developing Git for Windows further.
Happily, in the meantime the MSys2 project (https://msys2.github.io/)
emerged, and was chosen to be the base of the Git for Windows 2.x. Just
like MSys, MSys2 is a stripped down version of Cygwin, but it is
actively kept up-to-date with Cygwin's source code. Thereby, it already
supports Unicode internally, and it also offers the 64-bit support that
we yearned for since the beginning of the Git for Windows project.
MSys2 also ported the Pacman package management system from Arch Linux
and uses it heavily. This brings the same convenience to which Linux
users are used to from `yum` or `apt-get`, and to which MacOSX users are
used to from Homebrew or MacPorts, or BSD users from the Ports system,
to MSys2: a simple `pacman -Syu` will update all installed packages to
the newest versions currently available.
MSys2 is also *very* active, typically providing package updates
multiple times per week.
It still required a two-month effort to bring everything to a state
where Git's test suite passes, many more months until the first official
Git for Windows 2.x was released, and a couple of patches still await
their submission to the respective upstream projects. Yet without MSys2,
the modernization of Git for Windows would simply not have happened.
This commit lays the ground work to supporting MSys2-based Git builds.

On Mac OS X, getdelim() first became available with Xcode 4.1[1], which
was released the same day as OS X 10.7 "Lion", so assume getdelim()
availability from 10.7 onward. (As of this writing, OS X is at 10.10
"Yosemite".)
According to Wikipedia[2], 4.1 was also available for download by paying
developers on OS X 10.6 "Snow Leopard", so it's possible that some 10.6
machines may have getdelim(). However, as strbuf's use of getdelim() is
purely an optimization, let's be conservative and assume 10.6 and
earlier lack getdelim().
[1]: Or, possibly with Xcode 4.0, but that version is no longer
available for download, or not available to non-paying developers,
so testing is not possible.

We spend a lot of time in strbuf_getwholeline in a tight
loop reading characters from a stdio handle into a buffer.
The libc getdelim() function can do this for us with less
overhead. It's in POSIX.1-2008, and was a GNU extension
before that. Therefore we can't rely on it, but can fall
back to the existing getc loop when it is not available.
The HAVE_GETDELIM knob is turned on automatically for Linux,
where we have glibc. We don't need to set any new
feature-test macros, because we already define _GNU_SOURCE.
Other systems that implement getdelim may need to other
macros (probably _POSIX_C_SOURCE >= 200809L), but we can
address that along with setting the Makefile knob after
testing the feature on those systems.

The point of disallowing ".git" in the index is that we
would never want to accidentally overwrite files in the
repository directory. But this means we need to respect the
filesystem's idea of when two paths are equal. The prior
commit added a helper to make such a comparison for NTFS
and FAT32; let's use it in verify_path().
We make this check optional for two reasons:
1. It restricts the set of allowable filenames, which is
unnecessary for people who are not on NTFS nor FAT32.
In practice this probably doesn't matter, though, as
the restricted names are rather obscure and almost
certainly would never come up in practice.
2. It has a minor performance penalty for every path we

This patch ties the check to the core.protectNTFS config

Add a getnanotime() function that returns nanoseconds since 01/01/1970 as
unsigned 64-bit integer (i.e. overflows in july 2554). This is easier to
work with than e.g. struct timeval or struct timespec. Basing the timer on
the epoch allows using the results with other time-related APIs.
To simplify adaption to different platforms, split the implementation into
a common getnanotime() and a platform-specific highres_nanos() function.
The common getnanotime() function handles errors, falling back to
gettimeofday() if highres_nanos() isn't implemented or doesn't work.
getnanotime() is also responsible for normalizing to the epoch. The offset
to the system clock is calculated only once on initialization, i.e.
manually setting the system clock has no impact on the timer (except if
the fallback gettimeofday() is in use). Git processes are typically short
lived, so we don't need to handle clock drift.
The highres_nanos() function returns monotonically increasing nanoseconds
relative to some arbitrary point in time (e.g. system boot), or 0 on
failure. Providing platform-specific implementations should be relatively
easy, e.g. adapting to clock_gettime() as defined by the POSIX realtime
extensions is seven lines of code.
This version includes highres_nanos() implementations for:
* Linux: using clock_gettime(CLOCK_MONOTONIC)
* Windows: using QueryPerformanceCounter()
Todo:
* enable clock_gettime() on more platforms
* add Mac OSX version, e.g. using mach_absolute_time + mach_timebase_info

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.

this cheating lstat is used, and this is a simplest fix that is
also the cleanest direction to go in the long run.

cygwin: Remove the Win32 l/stat() implementation
We force core.filemode=false since c869753e (Force core.filemode to
false on Cygwin., 2006-12-30), even when the repository is on a
filesystem on which Cygwin can give us trustable filemodes, because
many native Windows applications the users use to edit files in the
working tree tend to (re)create files with executable bit randomly
set or reset. However, binary distribution of Git that is supplied
by the downstream project to its users has been built without this
consideration.
Drop NO_TRUSTABLE_FILEMODE from our default configuration so that
hand-compiled Git out of box will match theirs.
