55a87b20af hashmap: adjust documentation to reflect reality
The hashmap API is just complicated enough that even at least one
long-time Git contributor has to look up how to use it every time he
finds a new use case. When that happens, it is really useful if the
provided example code is correct...

While at it, "fix a memory leak", avoid statements before variable
declarations, fix a const -> no-const cast, several %l specifiers (which
want to be %ld), avoid using an undefined constant, call scanf()
correctly, use FLEX_ALLOC_STR() where appropriate, and adjust the style
here and there.

b76ee60b4b fetch-pack: use OBJECT_INFO_QUICK to avoid extra prepare_packed_git call
When I run git fetch, git tries to find object for each local and remote
refs.  Without specifying OBJECT_INFO_QUICK, has_object_file list up
entries in pack directory for each calls.

This patch makes git fetch fast for the repositories having large number
of refs, especially for windows because it's directory list up api is
much slower than linux.

236a397411 for-each-ref: let upstream/push report the remote ref name
There are times when scripts want to know not only the name of the
push branch on the remote, but also the name of the branch as known
by the remote repository.

An example of this is when a tool wants to push to the very same branch
from which it would pull automatically, i.e. the `<remote>` and the `<to>`
in `git push <remote> <from>:<to>` would be provided by
`%(upstream:remotename)` and `%(upstream:remoteref)`, respectively.

This patch offers the new suffix :remoteref for the `upstream` and `push`
atoms, allowing to show exactly that. Example:

	$ cat .git/config
	...
	[remote "origin"]
		url = https://where.do.we.come/from
		fetch = refs/heads/*:refs/remote/origin/*
	[branch "master"]
		remote = origin
		merge = refs/heads/master
	[branch "develop/with/topics"]
		remote = origin
		merge = refs/heads/develop/with/topics
	...

	$ git for-each-ref \
		--format='%(push) %(push:remoteref)' \
		refs/heads
	refs/remotes/origin/master refs/heads/master
	refs/remotes/origin/develop/with/topics refs/heads/develop/with/topics

728edb970a dir.c: make add_excludes aware of fscache during status
Teach read_directory_recursive() and add_excludes() to
be aware of optional fscache and avoid trying to open()
and fstat() non-existant ".gitignore" files in every
directory in the worktree.

The current code in add_excludes() calls open() and then
fstat() for a ".gitignore" file in each directory present
in the worktree.  Change that when fscache is enabled to
call lstat() first and if present, call open().

This seems backwards because both lstat needs to do more
work than fstat.  But when fscache is enabled, fscache will
already know if the .gitignore file exists and can completely
avoid the IO calls.  This works because of the lstat diversion
to mingw_lstat when fscache is enabled.

This reduced status times on a 350K file enlistment of the
Windows repo on a NVMe SSD by 0.25 seconds.

1b292ba9a4 status: reinstate --show-ignored-directory as a deprecated option
It was a bad idea to just remove that option from Git for Windows
v2.15.0, as early users of that (still experimental) option would have
been puzzled what they are supposed to do now.

So let's reintroduce the flag, but make sure to show the user good
advice how to fix this going forward.

We'll remove this option in a more orderly fashion either in v2.16.0 or
in v2.17.0.

a0f8f7546e for-each-ref: let upstream/push optionally report the remote name
There are times when e.g. scripts want to know not only the name of the
upstream branch on the remote repository, but also the name of the
remote.

This patch offers the new suffix :remotename for the upstream and for
the push atoms, allowing to show exactly that. Example:

	$ cat .git/config
	...
	[remote "origin"]
		url = https://where.do.we.come/from
		fetch = refs/heads/*:refs/remote/origin/*
	[remote "hello-world"]
		url = https://hello.world/git
		fetch = refs/heads/*:refs/remote/origin/*
		pushURL = hello.world:git
		push = refs/heads/*:refs/heads/*
	[branch "master"]
		remote = origin
		pushRemote = hello-world
	...

	$ git for-each-ref \
	  --format='%(upstream) %(upstream:remotename) %(push:remotename)' \
	  refs/heads/master
	refs/remotes/origin/master origin hello-world

The implementation chooses *not* to DWIM the push remote if no explicit
push remote was configured; The reason is that it is possible to DWIM this
by using

	%(if)%(push:remotename)%(then)
		%(push:remotename)
	%(else)
		%(upstream:remotename)
	%(end)

while it would be impossible to "un-DWIM" the information in case the
caller is really only interested in explicit push remotes.

While `:remote` would be shorter, it would also be a bit more ambiguous,
and it would also shut the door e.g. for `:remoteref` (which would
obviously refer to the corresponding ref in the remote repository).

Note: the dashless, non-CamelCased form `:remotename` follows the
example of the `:trackshort` example.

ignored because it is listed to be ignored in the ignore/exclude
mechanism can be handled differently from a directory that ends up
to be ignored only because all files in it are ignored.

ed33677007 status: add option to show ignored files differently
Teach the status command more flexibility in how ignored files are
reported. Currently, the reporting of ignored files and untracked
files are linked. You cannot control how ignored files are reported
independently of how untracked files are reported (i.e. `all` vs
`normal`). This makes it impossible to show untracked files with the
`all` option, but show ignored files with the `normal` option.

This work 1) adds the ability to control the reporting of ignored
files independently of untracked files and 2) introduces the concept
of status reporting ignored paths that explicitly match an ignored
pattern. There are 2 benefits to these changes: 1) if a consumer needs
all untracked files but not all ignored files, there is a performance
benefit to not scanning all contents of an ignored directory and 2)
returning ignored files that explicitly match a path allow a consumer
to make more informed decisions about when a status result might be
stale.

This commit implements --ignored=matching with --untracked-files=all.
The following commit will implement --ignored=matching with
--untracked=files=normal.

As an example of where this flexibility could be useful is that our
application (Visual Studio) runs the status command and presents the
output. It shows all untracked files individually (e.g. using the
'--untracked-files==all' option), and would like to know about which
paths are ignored. It uses information about ignored paths to make
decisions about when the status result might have changed.
Additionally, many projects place build output into directories inside
a repository's working directory (e.g. in "bin/" and "obj/"
directories). Normal usage is to explicitly ignore these 2 directory
names in the .gitignore file (rather than or in addition to the *.obj
pattern).If an application could know that these directories are
explicitly ignored, it could infer that all contents are ignored as
well and make better informed decisions about files in these
directories. It could infer that any changes under these paths would
not affect the output of status. Additionally, there can be a
significant performance benefit by avoiding scanning through ignored
directories.

When status is set to report matching ignored files, it has the
following behavior. Ignored files and directories that explicitly
match an exclude pattern are reported. If an ignored directory matches
an exclude pattern, then the path of the directory is returned. If a
directory does not match an exclude pattern, but all of its contents
are ignored, then the contained files are reported instead of the
directory.

4feb7bbb5d Fix .git/ discovery at the root of UNC shares
A very common assumption in Git's source code base is that
offset_1st_component() returns either 0 for relative paths, or 1 for
absolute paths that start with a slash. In other words, the return value
is either 0 or points just after the dir separator.

This assumption is not fulfilled when calling offset_1st_component()
e.g. on UNC paths on Windows, e.g. "//my-server/my-share". In this case,
offset_1st_component() returns the length of the entire string (which is
correct, because stripping the last "component" would not result in a
valid directory), yet the return value still does not point just after a
dir separator.

This assumption is most prominently seen in the
setup_git_directory_gently_1() function, where we want to append a
".git" component and simply assume that there is already a dir
separator. In the UNC example given above, this assumption is incorrect.

As a consequence, Git will fail to handle a worktree at the top of a UNC
share correctly.

Let's fix this by adding a dir separator specifically for that case: we
found that there is no first component in the path and it does not end
in a dir separator? Then add it.

a7b244c555 mingw: use CreateHardLink directly
It was observed that the current implementation of of get_proc_addr()
fails to load the kernel32.dll with code ERROR_INVALID_PARAMETER.
Probably the reason is that kernel32.dll is already loaded. The
behavior was seen at Windows SP1, both 32bit and 64bit. Probably it
would behave same way in some or all other Windows versions.

This breaks all usages of "clone --local", including the automatic
tests where they call it.

The function CreateHardLink is available in all supported Windows
versions (since Windows XP), so there is no more need to resolve it
in runtime.

8dcf591e73 Merge branch 'busybox-w32'
This topic branch brings slightly experimental changes supporting Git
for Windows to use BusyBox-w32 to execute its shell scripts as well as
its test suite.

The test suite can be run by installing the test artifacts into a MinGit
that has busybox.exe (and using Git for Windows' SDK's Perl for now, as
the test suite requires Perl even when NO_PERL is set, go figure) by
using the `install-mingit-test-artifacts` Makefile target with the
DESTDIR variable pointing to the top-level directory of the MinGit
installation.

To facilitate running the test suite (without having `make` available,
as `make.exe` is not part of MinGit), this branch brings an experimental
patch to the `test-run-command` helper to run Git's test suite. It is
still very experimental, though: in this developer's tests it seemed
that the `poll()` emulation required for `run_parallel_processes()` to
work sometimes hiccups on Windows, causing infinite "hangs". It is also
possible that BusyBox itself has problems writing to the pipes opened by
`test-run-command` (and merging this branch will help investigate
further). Caveat emptor.

c10132e7d4 t9350: skip ISO-8859-1 test when the environment is always-UTF-8
In the BusyBox-w32 version that is currently under consideration for
MinGit for Windows (to reduce the .zip size, and to avoid problems with
the MSYS2 runtime), the UTF-16 environment present in Windows is
considered to be authoritative, and the 8-bit version is always in UTF-8
encoding.

As a consequence, the ISO-8859-1 test in t9350-fast-export (which tries
to set GIT_AUTHOR_NAME to a ISO-8859-1 encoded value) *must* fail in
that setup.

So let's detect when it would fail (due to an environment being purely
kept UTF-8 encoded), and skip that test in that case.

f4c2750239 Implement pthread_cond_t with Win32 CONDITION_VARIABLE
Win32 CONDITION_VARIABLE has better performance and is easier to
maintain.

Since CONDITION_VARIABLE is not available in Windows XP and below,
old implementation of pthread_cond_t is kept under define guard
'GIT_WIN_XP_SUPPORT'. To enable old implementation, build with
make CFLAGS="-DGIT_WIN_XP_SUPPORT".

60c06fcdb6 t9200: skip tests when $PWD contains a colon
On Windows, the current working directory is pretty much guaranteed to
contain a colon. If we feed that path to CVS, it mistakes it for a
separator between host and port, though.

This has not been a problem so far because Git for Windows uses MSYS2's
Bash using a POSIX emulation layer that also pretends that the current
directory is a Unix path (at least as long as we're in a shell script).

However, that is rather limiting, as Git for Windows also explores other
ports of other Unix shells. One of those is BusyBox-w32's ash, which is
a native port (i.e. *not* using any POSIX emulation layer, and certainly
not emulating Unix paths).

So let's just detect if there is a colon in $PWD and punt in that case.

5d04bef2d5 t7063: when running under BusyBox, avoid unsupported find option
BusyBox' find implementation does not understand the -ls option, so

60fdc372bb t5813: allow for $PWD to be a Windows path
Git for Windows uses MSYS2's Bash to run the test suite, which comes
with benefits but also at a heavy price: on the plus side, MSYS2's
POSIX emulation layer allows us to continue pretending that we are on a
Unix system, e.g. use Unix paths instead of Windows ones, yet this is
bought at a rather noticeable performance penalty.

There *are* some more native ports of Unix shells out there, though,
most notably BusyBox-w32's ash. These native ports do not use any POSIX
emulation layer (or at most a *very* thin one, choosing to avoid
features such as fork() that are expensive to emulate on Windows), and
they use native Windows paths (usually with forward slashes instead of
backslashes, which is perfectly legal in almost all use cases).

And here comes the problem: with a $PWD looking like, say,
C:/git-sdk-64/usr/src/git/t/trash directory.t5813-proto-disable-ssh
Git's test scripts get quite a bit confused, as their assumptions have
been shattered. Not only does this path contain a colon (oh no!), it
also does not start with a slash.

This is a problem e.g. when constructing a URL as t5813 does it:
ssh://remote$PWD. Not only is it impossible to separate the "host" from
the path with a $PWD as above, even prefixing $PWD by a slash won't
work, as /C:/git-sdk-64/... is not a valid path.

As a workaround, detect when $PWD does not start with a slash on
Windows, and simply strip the drive prefix, using an obscure feature of
Windows paths: if an absolute Windows path starts with a slash, it is
implicitly prefixed by the drive prefix of the current directory. As we
are talking about the current directory here, anyway, that strategy
works.

98467d886f t5605: special-case hardlink test for BusyBox-w32
When t5605 tries to verify that files are hardlinked (or that they are
not), it uses the `-links` option of the `find` utility.

BusyBox' implementation does not support that option, and BusyBox-w32's
lstat() does not even report the number of hard links correctly (for
performance reasons).

So let's just switch to a different method that actually works on
Windows.

f91f5b00a3 t5532: workaround for BusyBox on Windows
While it may seem super convenient to some old Unix hands to simpy
require Perl to be available when running the test suite, this is a
major hassle on Windows, where we want to verify that Perl is not,
actually, required in a NO_PERL build.

As a super ugly workaround, we "install" a script into /usr/bin/perl
reading like this:

	#!/bin/sh

	# We'd much rather avoid requiring Perl altogether when testing
	# an installed Git. Oh well, that's why we cannot have nice
	# things.
	exec c:/git-sdk-64/usr/bin/perl.exe "$@"

The problem with that is that BusyBox assumes that the #! line in a
script refers to an executable, not to a script. So when it encounters
the line #!/usr/bin/perl in t5532's proxy-get-cmd, it barfs.

Let's help this situation by simply executing the Perl script with the
"interpreter" specified explicitly.

700ff5646b t5003: skip unzip -a tests with BusyBox
BusyBox' unzip is working pretty well. But Git's tests want to abuse it
to not only extract files, but to convert their line endings on the fly,
too. BusyBox' unzip does not support that, and it would appear that
it would require rather intrusive changes.

So let's just work around this by skipping the test case that uses
`unzip -a` and the subsequent test cases expecting `unzip -a`'s output.

b626e5b85b t5003: use binary file from t/diff-lib/
At some stage, t5003-archive-zip wants to add a file that is not ASCII.
To that end, it uses /bin/sh. But that file may actually not exist (it
is too easy to forget that not all the world is Unix/Linux...)! Besides,
we already have perfectly fine binary files intended for use solely by
the tests. So let's use one of them instead.

81f9b3dc94 t4124: avoid using "normal" diff mode
Everybody and their dogs, cats and other pets settled on using unified
diffs. It is a really quaint holdover from a long-gone era that GNU diff
outputs "normal" diff by default.

Yet, t4124 relied on that mode.

This mode is so out of fashion in the meantime, though, that e.g.
BusyBox' diff decided not even to bother to support it. It only supports
unified diffs.

So let's just switch away from "normal" diffs and use unified diffs, as
we really are only interested in the `+` lines.

09cd022c6b t1300: mark all test cases with funny filenames as !MINGW
On Windows, it is impossible to create a file whose name contains a
quote character. We already excluded test cases using such files from
running on Windows when git.exe itself was tested.

However, we still had two test cases that try to create such a file, and
redirect stdin from such a file, respectively. This *seems* to work in
Git for Windows' Bash due to an obscure feature inherited from Cygwin:
illegal filename characters are simply mapped into/from a private UTF-8
page. Pure Win32 programs (such as git.exe) *still* cannot work with
those files, of course, but at least Unix shell scripts pretend to be
able to.

This entire strategy breaks down when switching to any Unix shell
lacking support for that private UTF-8 page trick, e.g. BusyBox-w32's
ash. So let's just exclude test cases that test whether the Unix shell
can redirect to/from files with "funny names" those from running on
Windows, too.
