fe9e2aefd4 pretty: recalculate duplicate short hashes
b9c6232138 (--format=pretty: avoid calculating expensive expansions
twice) optimized adding short hashes multiple times by using the
fact that the output strbuf was only ever simply appended to and
copying the added string from the previous run.  That prerequisite
is no longer given; we now have modfiers like %< and %+ that can
cause the cache to lose track of the correct offsets.  Remove it.

773a88914f doc: do not use rm .git/index when normalizing line endings
When illustrating how to normalize the line endings, the
documentation in gitattributes tells the user to `rm .git/index`.

This is incorrect for two reasons:

 - Users shouldn't be instructed to mess around with the internal
   implementation of Git using raw file system tools like `rm`.

 - Within a submodule or an additional working tree `.git` is just a
   file containing a `gitdir: <path>` pointer into the real `.git`
   directory.  Therefore `rm .git/index` does not work.

The purpose of the `rm .git/index` instruction is to remove all entries
from the index without touching the working tree.  The way to do this
with Git is to use `read-tree --empty`.

a36e14b3aa fixup! Win32: add a cache below mingw's lstat and dirent implementations
fscache_clear was crashing because when using hashmap_iter_next
method the next entry will be saved.  Meanwhile the call to
fscache_release will free the directory and the list of entries
for the directory.  This causes the next entry saved by the iter
to be freed, invalid and the crash with the next loop iteration.

This changes the clear to simple call hashmap_free to free
the hashmap and all the entries and then call hashmap_init to
reinitialize the hashmap for the next fscache use.  The reason
this is safe is fscache_clear is only called from fscache_enable
when this cache is being disabled which is only called in
preload_index after all the thread have exited.
It is also guarded by the critical section mutex.

0b1bb0c032 Configure Git contribution guidelines for github.com
Many open source projects use github.com for their contribution process.
Although we mirror the Git core repository to github.com [1] we do not
use any other github.com service. This is unknown/unexpected to a
number of (potential) contributors and consequently they create Pull
Requests against our mirror with their contributions. These Pull
Requests become stale. This is frustrating to them as they think we
ignore them and it is also unsatisfactory for us as we miss potential
code improvements and/or new contributors.

GitHub contribution guidelines and a GitHub Pull Request template that
is visible to every Pull Request creator can be configured with special
files in a Git repository [2]. Let's make use of this!

22fc703ec9 git-stash: fix pushing stash with pathspec from subdir
The `git stash push` command recently gained the ability to get a
pathspec as its argument to only stash matching files. Calling this
command from a subdirectory does not work, though, as one of the first
things we do is changing to the top level directory without keeping
track of the prefix from which the command is being run.

Fix the shortcoming by storing the prefix previous to the call to
`cd_to_toplevel` and then subsequently using `git rev-parse --prefix` to
correctly resolve the pathspec. Add a test to catch future breakage of
this usecase.

bb8efa1772 t3200: add test for single parameter passed to -m option
Add a test for the case when only one parameter is passed to '-m'
(move/rename) option.

For example - if 'git branch -m bbb' is run while checked out on aaa
branch, it should rename the currently checked out branch to bbb.
There was no test for this particular case with only one parameter
for -m option. However, there's one similar test case for -M option.

Add test for making sure HEAD points to the bbb (new branch name). Also
add a test for making sure the reflog that is moved to 'bbb' retains
entries created for the currently checked out branch. Note that since
the topmost entry on reflog for bbb will be about branch creation, we
compare bbb@{1} (instead of bbb@{0}) with aaa@{0} to make sure the
reflog for bbb retains entries from aaa.

dffc651ed1 revision.c: stricter parsing of '--early-output'
The parsing of '--early-output' with or without its optional integer
argument allowed bogus options like '--early-output-foobarbaz' to slip
through and be ignored.

Fix it by parsing '--early-output' in the same way as other options
with an optional argument are parsed.  Furthermore, use strtoul_ui()
to parse the optional integer argument and to refuse negative numbers.

While at it, use skip_prefix() instead of starts_with() and magic
numbers.

e35b6ac56f revision.h: turn rev_info.early_output back into an unsigned int
rev_info.early_output started out as an unsigned int in cdcefbc97 (Add
"--early-output" log flag for interactive GUI use, 2007-11-03), but
later it was turned into a single bit in a bit field in cc243c3ce
(show: --ignore-missing, 2011-05-18) without explanation, though the
code using it still expects it to be a regular integer type and uses
it as a counter.  Consequently, any even number given via
'--early-output=<N>', or indeed a plain '--early-output' defaulting to
100 effectively disabled the feature.

Turn rev_info.early_output back into its origin unsigned int data
type, making '--early-output' work again.

7c2115aa07 t5313: make extended-table test more deterministic
Commit a1283866b (t5313: test bounds-checks of
corrupted/malicious pack/idx files, 2016-02-25) added a test
that requires our corrupted pack index to have two objects.
The entry for the first one remains untouched, but we
corrupt the entry for second one. Since the index stores the
entries in sha1-sorted order, this means that the test must
make sure that the sha1 of the object we expect to be
corrupted ("$object") sorts after the other placeholder
object.

That commit used the HEAD commit as the placeholder, but the
script never calls test_tick. That means that the commit
object (and thus its sha1) depends on the timestamp when the
test script is run. This usually works in practice, because
the sha1 of $object starts with "fff". The commit object
will sort after that only 1 in 4096 times, but when it does
the test will fail.

One obvious solution is to add the test_tick call to get a
deterministic commit sha1. But since we're relying on the
sort order for the test to function, let's make that very
explicit by just generating a second blob with a known sha1.

45c61207ba mingw: try to create symlinks without elevated permissions
With Windows 10 Build 14972 in Developer Mode, a new flag is supported
by CreateSymbolicLink() to create symbolic links even when running
outside of an elevated session (which was previously required).

This new flag is called SYMBOLIC_LINK_FLAG_ALLOW_UNPRIVILEGED_CREATE and
has the numeric value 0x02.

Previous Windows 10 versions will not understand that flag and return an
ERROR_INVALID_PARAMETER, therefore we have to be careful to try passing
that flag only when the build number indicates that it is supported.

For more information about the new flag, see this blog post:
https://blogs.windows.com/buildingapps/2016/12/02/symlinks-windows-10/

This patch is loosely based on the patch submitted by Samuel D. Leslie
as https://github.com/git-for-windows/git/pull/1184.

eef3ade611 mingw: kill unterminated child processes on signals
Git for Windows' MSYS2 runtime was just adjusted to kill processes
gently, by injecting a thread that calls ExitProcess(). In case of
signals (such as when handling Ctrl+C in a MinTTY window), the exit code
is 128 + sign_no, as expected by Git's source code.

However, as there is no POSIX signal handling on Windows, no signal
handlers are called. Instead, functions registered via atexit() are
called. We work around that by testing the exit code explicitly.

This fixes the Git for Windows side of the bug where  interrupting `git
clone https://...` would send the spawned-off `git remote-https` process
into the background instead of interrupting it, i.e. the clone would
continue and its progress would be reported mercilessly to the console
window without the user being able to do anything about it (short of
firing up the task manager and killing the appropriate task manually).

4cb055358d mingw: kill child processes in a gentler way
The TerminateProcess() function does not actually leave the child
processes any chance to perform any cleanup operations. This is bad
insofar as Git itself expects its signal handlers to run.

A symptom is e.g. a left-behind .lock file that would not be left behind
if the same operation was run, say, on Linux.

To remedy this situation, we use an obscure trick: we inject a thread
into the process that needs to be killed and to let that thread run the
ExitProcess() function with the desired exit status. Thanks J Wyman for
describing this trick.

The advantage is that the ExitProcess() function lets the atexit
handlers run. While this is still different from what Git expects (i.e.
running a signal handler), in practice Git sets up signal handlers and
atexit handlers that call the same code to clean up after itself.

In case that the gentle method to terminate the process failed, we still
fall back to calling TerminateProcess(), but in that case we now also
make sure that processes spawned by the spawned process are terminated;
TerminateProcess() does not give the spawned process a chance to do so
itself.

Please note that this change only affects how Git for Windows tries to
terminate processes spawned by Git's own executables. Third-party
software that *calls* Git and wants to terminate it *still* need to make
sure to imitate this gentle method, otherwise this patch will not have
any effect.

a5620c34a1 Remove support for XP specific config location
Current Git for Windows supports an additional configuration location
for system setting. On contemporary versionws of Windows this is
$PROGRAMDATA/Git/config. But XP does not know about $PRORGRAMDATA so
$ALLUSERSPROFILE/Application Data/Git/config was used.

XP itself is EOL for quite some time and Git for Windows ceased to
support it officially with version 2.10.0 (release 3 Sep 2016).

3f7c659825 Merge branch 'drive-prefix'
This topic branch allows us to specify absolute paths without the drive
prefix e.g. when cloning.

Example:

	C:\Users\me> git clone https://github.com/git/git \upstream-git

This will clone into a new directory C:\upstream-git, in line with how
Windows interprets absolute paths.

4c332ac520 Merge branch 'skip-gettext-when-possible'
This topic branch allows us to skip the gettext initialization
when the locale directory does not even exist.

This saves 150ms out of 210ms for a simply `git version` call on
Windows, and it most likely will help scripts that call out to
`git.exe` hundreds of times.

7d43c61308 mingw: fix isatty() after dup2()
We newly handle isatty() by special-casing the stdin/stdout/stderr file
descriptors, caching the return value. However, we missed the case where
dup2() overrides the respective file descriptor.

That poses a problem e.g. where the `show` builtin asks for a pager very
early, the `setup_pager()` function sets the pager depending on the
return value of `isatty()` and then redirects stdout. Subsequently,
`cmd_log_init_finish()` calls `setup_pager()` *again*. What should
happen now is that `isatty()` reports that stdout is *not* a TTY and
consequently stdout should be left alone.

Let's override dup2() to handle this appropriately.

This fixes https://github.com/git-for-windows/git/issues/1077
