To complement the `--stdin` and `--literally` test cases that verify that we can hash files larger than 4GB on 64-bit platforms using the LLP64 data model, here is a test case that exercises `hash-object` _without_ any options. Just as before, we use the `big` file from the previous test case if it exists to save on setup time, otherwise generate it.

After importing anything with fast-import, we should always let the garbage collector do its job, since the objects are written to disk inefficiently. This brings down an initial import of http://selenic.com/hg from about 230 megabytes to about 14. In the future, we may want to make this configurable on a per-remote basis, or maybe teach fast-import about it in the first place. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
On Windows, there are several categories of absolute paths. One such category starts with a backslash and is implicitly relative to the drive associated with the current working directory. Example: c: git clone https://github.com/git-for-windows/git \G4W should clone into C:\G4W. Back in 2017, Juan Carlos Arevalo Baeza reported a bug in Git's handling of those absolute paths was identified, and fixed. Let's make sure that it stays fixed.

Windows' equivalent to "bind mounts", NTFS junction points, can be unlinked without affecting the mount target. This is clearly what users expect to happen when they call `git clean -dfx` in a worktree that contains NTFS junction points: the junction should be removed, and the target directory of said junction should be left alone (unless it is inside the worktree).

Thorough benchmarking with repacking a subset of linux.git (the commit history reachable from 93a6fef ([PATCH] fix the SYSCTL=n compilation, 2007-02-28), to be precise) suggest that this allocator is on par, in multi-threaded situations maybe even better than nedmalloc: `git repack -adfq` with mimalloc, 8 threads: 31.166991900 27.576763800 28.712311000 27.373859000 27.163141900 `git repack -adfq` with nedmalloc, 8 threads: 31.915032900 27.149883100 28.244933700 27.240188800 28.580849500 In a different test using GitHub Actions build agents (probably single-threaded, a core-strength of nedmalloc)): `git repack -q -d -l -A --unpack-unreachable=2.weeks.ago` with mimalloc: 943.426 978.500 939.709 959.811 954.605 `git repack -q -d -l -A --unpack-unreachable=2.weeks.ago` with nedmalloc: 995.383 952.179 943.253 963.043 980.468 While these measurements were not executed with complete scientific rigor, as no hardware was set aside specifically for these benchmarks, it shows that mimalloc and nedmalloc perform almost the same, nedmalloc with a bit higher variance and also slightly higher average (further testing suggests that nedmalloc performs worse in multi-threaded situations than in single-threaded ones). In short: mimalloc seems to be slightly better suited for our purposes than nedmalloc. Seeing that mimalloc is developed actively, while nedmalloc ceased to see any updates in eight years, let's use mimalloc on Windows instead.

Since commit 0c499ea (send-pack: demultiplex a sideband stream with status data, 2010-02-05) the send-pack builtin uses the side-band-64k capability if advertised by the server. Unfortunately this breaks pushing over the dump git protocol if used over a network connection. The detailed reasons for this breakage are (by courtesy of Jeff Preshing, quoted from https://groups.google.com/d/msg/msysgit/at8D7J-h7mw/eaLujILGUWoJ): MinGW wraps Windows sockets in CRT file descriptors in order to mimic the functionality of POSIX sockets. This causes msvcrt.dll to treat sockets as Installable File System (IFS) handles, calling ReadFile, WriteFile, DuplicateHandle and CloseHandle on them. This approach works well in simple cases on recent versions of Windows, but does not support all usage patterns. In particular, using this approach, any attempt to read & write concurrently on the same socket (from one or more processes) will deadlock in a scenario where the read waits for a response from the server which is only invoked after the write. This is what send_pack currently attempts to do in the use_sideband codepath. The new config option `sendpack.sideband` allows to override the side-band-64k capability of the server, and thus makes the dumb git protocol work. Other transportation methods like ssh and http/https still benefit from the sideband channel, therefore the default value of `sendpack.sideband` is still true.

The native Windows HTTPS backend is based on Secure Channel which lets the caller decide how to handle revocation checking problems caused by missing information in the certificate or offline CRL distribution points. Unfortunately, cURL chose to handle these problems differently than OpenSSL by default: while OpenSSL happily ignores those problems (essentially saying "¯\_(ツ)_/¯"), the Secure Channel backend will error out instead. As a remedy, the "no revoke" mode was introduced, which turns off revocation checking altogether. This is a bit heavy-handed. We support this via the `http.schannelCheckRevoke` setting. In curl/curl#4981, we contributed an opt-in "best effort" strategy that emulates what OpenSSL seems to do. In Git for Windows, we actually want this to be the default. This patch makes it so, introducing it as a new value for the `http.schannelCheckRevoke" setting, which now becmes a tristate: it accepts the values "false", "true" or "best-effort" (defaulting to the last one).

Include the environment's CMAKE_EXPORT_COMPILE_COMMANDS value which may have been propogated to CMake's internal value. Testing the CMAKE_EXPORT_COMPILE_COMMANDS processing can be difficult in the Visual Studio environment, as it may be cached in many places.

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. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
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.

Rather than using private IFTTT Applets that send mails to this maintainer whenever a new version of a Git for Windows component was released, let's use the power of GitHub workflows to make this process publicly visible. This workflow monitors the Atom/RSS feeds, and opens a ticket whenever a new version was released. Note: Bash sometimes releases multiple patched versions within a few minutes of each other (i.e. 5.1p1 through 5.1p4, 5.0p15 and 5.0p16). The MSYS2 runtime also has a similar system. We can address those patches as a group, so we shouldn't get multiple issues about them. Note further: We're not acting on newlib releases, OpenSSL alphas, Perl release candidates or non-stable Perl releases. There's no need to open issues about them.

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. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
The Windows Subsystem for Linux (WSL) version 2 allows to use `chmod` on NTFS volumes provided that they are mounted with metadata enabled (see https://devblogs.microsoft.com/commandline/chmod-chown-wsl-improvements/ for details), for example: $ chmod 0755 /mnt/d/test/a.sh In order to facilitate better collaboration between the Windows version of Git and the WSL version of Git, we can make the Windows version of Git also support reading and writing NTFS file modes in a manner compatible with WSL. Since this slightly slows down operations where lots of files are created (such as an initial checkout), this feature is only enabled when `core.WSLCompat` is set to true. Note that you also have to set `core.fileMode=true` in repositories that have been initialized without enabling WSL compatibility. There are several ways to enable metadata loading for NTFS volumes in WSL, one of which is to modify `/etc/wsl.conf` by adding: ``` [automount] enabled = true options = "metadata,umask=027,fmask=117" ``` And reboot WSL. It can also be enabled temporarily by this incantation: $ sudo umount /mnt/c && sudo mount -t drvfs C: /mnt/c -o metadata,uid=1000,gid=1000,umask=22,fmask=111 It's important to note that this modification is compatible with, but does not depend on WSL.

To fix the problem addressed by the revert, but _still_ keep the problem with Windows Terminal fixed, let's revert the revert, with a twist: we restrict the save/restore _specifically_ to the case where `vi` (or `vim`) is called, and do not do the same for any other editor.

However, several applications (e.g., 'scalar') utilize the original config setting, so it should be preserved for a deprecation period before complete removal: * if 'core.fsmonitor' is a boolean, the user is correctly using the new config syntax; do not use 'core.useBuiltinFSMonitor'. * if 'core.fsmonitor' is unspecified, use 'core.useBuiltinFSMonitor'. * if 'core.fsmonitor' is a path, override and use the builtin FSMonitor if 'core.useBuiltinFSMonitor' is 'true'; otherwise, use the FSMonitor hook indicated by the path.

There is a bug in the logic of 816db62 that means we are responding to the `ntlm_allow=1` signal too late in the auth retry codepath; we've already made the second-attempt request! Move adding of NTLM as a valid auth method to `http_request_reauth` right after the credential helper is consulted following the first request, but (now) before we made the second request.
