Atomic append on windows is only supported on local disk files, and it may
cause errors in other situations, e.g. network file system. If that is the
case, this config option should be used to turn atomic append off.

From the documentation of said setting:

	This boolean will enable fsync() when writing object files.

	This is a total waste of time and effort on a filesystem that
	orders data writes properly, but can be useful for filesystems
	that do not use journalling (traditional UNIX filesystems) or
	that only journal metadata and not file contents (OS X’s HFS+,
	or Linux ext3 with "data=writeback").

The most common file system on Windows (NTFS) does not guarantee that
order, therefore a sudden loss of power (or any other event causing an
unclean shutdown) would cause corrupt files (i.e. files filled with
NULs). Therefore we need to change the default.

Note that the documentation makes it sound as if this causes really bad
performance. In reality, writing loose objects is something that is done
only rarely, and only a handful of files at a time.

Whith Windows 2000, Microsoft introduced a flag to the PE header to mark executables as
"terminal server aware". Windows terminal servers provide a redirected Windows directory and
redirected registry hives when launching legacy applications without this flag set. Since we
do not use any INI files in the Windows directory and don't write to the registry, we don't
need  this additional preparation. Telling the OS that we don't need this should provide
slightly improved startup times in terminal server environments.

When building for supported Windows Versions with MSVC the /TSAWARE linker flag is
automatically set, but MinGW requires us to set the --tsaware flag manually.

This partially addresses git-for-windows#3935.

In f9b7573 (repository: free fields before overwriting them,
2017-09-05), Git was taught to release memory before overwriting it, but
357a03e (repository.c: move env-related setup code back to
environment.c, 2018-03-03) changed the code so that it would not
_always_ be overwritten.

As a consequence, the `commondir` attribute would point to
already-free()d memory.

This seems not to cause problems in core Git, but there are add-on
patches in Git for Windows where the `commondir` attribute is
subsequently used and causing invalid memory accesses e.g. in setups
containing old-style submodules (i.e. the ones with a `.git` directory
within theirs worktrees) that have `commondir` configured.

This fixes git-for-windows#4083.

It is merely a historical wart that, say, `git-commit` exists in the
`libexec/git-core/` directory, a tribute to the original idea to let Git
be essentially a bunch of Unix shell scripts revolving around very few
"plumbing" (AKA low-level) commands.

Git has evolved a lot from there. These days, most of Git's
functionality is contained within the `git` executable, in the form of
"built-in" commands.

To accommodate for scripts that use the "dashed" form of Git commands,
even today, Git provides hard-links that make the `git` executable
available as, say, `git-commit`, just in case that an old script has not
been updated to invoke `git commit`.

Those hard-links do not come cheap: they take about half a minute for
every build of Git on Windows, they are mistaken for taking up huge
amounts of space by some Windows Explorer versions that do not
understand hard-links, and therefore many a "bug" report had to be
addressed.

The "dashed form" has been officially deprecated in Git version 1.5.4,
which was released on February 2nd, 2008, i.e. a very long time ago.
This deprecation was never finalized by skipping these hard-links, but
we can start the process now, in Git for Windows.

In 436a422 (max_tree_depth: lower it for clangarm64 on Windows,
2025-04-23), I provided a work-around for a nasty issue with clangarm
builds, where the stack is exhausted before the maximal tree depth is
reached, and the resulting error cannot easily be handled by Git
(because it would require Windows-specific handling).

Turns out that this is not at all limited to ARM64. In my tests with
CLANG64 in MSYS2 on the GitHub Actions runners, the test t6700.4 failed
in the exact same way. What's worse: The limit needs to be quite a bit
lower for x86_64 than for aarch64. In aforementioned tests, the breaking
point was 1232: With 1231 it still worked as expected, with 1232 it
would fail with the `STATUS_STACK_OVERFLOW` incorrectly mapped to exit
code 127. For comparison, in my tests on GitHub Actions' Windows/ARM64
runners, the breaking point was 1439 instead.

Therefore the condition needs to be adapted once more, to accommodate
(with some safety margin) both aarch64 and x86_64 in clang-based builds
on Windows, to let that test pass.

…ctory

Internally, Git expects the environment variable `HOME` to be set, and
to point to the current user's home directory.

This environment variable is not set by default on Windows, and
therefore Git tries its best to construct one if it finds `HOME` unset.

There are actually two different approaches Git tries: first, it looks
at `HOMEDRIVE`/`HOMEPATH` because this is widely used in corporate
environments with roaming profiles, and a user generally wants their
global Git settings to be in a roaming profile.

Only when `HOMEDRIVE`/`HOMEPATH` is either unset or does not point to a
valid location, Git will fall back to using `USERPROFILE` instead.

However, starting with Windows Vista, for secondary logons and services,
the environment variables `HOMEDRIVE`/`HOMEPATH` point to Windows'
system directory (usually `C:\Windows\system32`).

That is undesirable, and that location is usually write-protected anyway.

So let's verify that the `HOMEDRIVE`/`HOMEPATH` combo does not point to
Windows' system directory before using it, falling back to `USERPROFILE`
if it does.

This fixes git-for-windows#2709

winuser.h contains the definition of RT_MANIFEST that our LLVM based
toolchain needs to understand that we want to embed
compat/win32/git.manifest as an application manifest. It currently just
embeds it as additional data that Windows doesn't understand.

This also helps our GCC based toolchain understand that we only want one
copy embedded. It currently embeds one working assembly manifest and one
nearly identical, but useless copy as additional data.

This also teaches our Visual Studio based buildsystems to pick up the
manifest file from git.rc. This means we don't have to explicitly specify
it in contrib/buildsystems/Generators/Vcxproj.pm anymore. Slightly
counter-intuitively this also means we have to explicitly tell Cmake
not to embed a default manifest.

This will help with Git for Windows' maintenance going forward: It
allows Git for Windows to switch its primary libcurl to a variant
without the OpenSSL backend, while still loading an alternate when
setting `http.sslBackend = openssl`.

This is necessary to avoid maintenance headaches with upgrading OpenSSL:
its major version name is encoded in the shared library's file name and
hence major version updates (temporarily) break libraries that are
linked against the OpenSSL library.

When running Git for Windows on a remote APFS filesystem, it would
appear that the `mingw_open_append()`/`write()` combination would fail
almost exactly like on some CIFS-mounted shares as had been reported in
git-for-windows#2753, albeit with a
different `errno` value.

Let's handle that `errno` value just the same, by suggesting to set
`windows.appendAtomically=false`.

Windows 10 version 1511 (also known as Anniversary Update), according to
https://learn.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences
introduced native support for ANSI sequence processing. This allows
using colors from the entire 24-bit color range.

All we need to do is test whether the console's "virtual processing
support" can be enabled. If it can, we do not even need to start the
`console_thread` to handle ANSI sequences.

Or, almost all we need to do: When `console_thread()` does its work, it
uses the Unicode-aware `write_console()` function to write to the Win32
Console, which supports Git for Windows' implicit convention that all
text that is written is encoded in UTF-8. The same is not necessarily
true if native ANSI sequence processing is used, as the output is then
subject to the current code page. Let's ensure that the code page is set
to `CP_UTF8` as long as Git writes to it.

By default, the buffer type of Windows' `stdout` is unbuffered (_IONBF),
and there is no need to manually fflush `stdout`.

But some programs, such as the Windows Filtering Platform driver
provided by the security software, may change the buffer type of
`stdout` to full buffering. This nees `fflush(stdout)` to be called
manually, otherwise there will be no output to `stdout`.

However, this is not how most users run Git for Windows: As the majority
of Git for Windows' users seem to be on Windows 10 and newer, likely
having enabled Developer Mode (which allows creating symbolic links
without administrator privileges), they will run with symlink support
enabled.

This is the reason why it is crucial to get the fixes for CVE-2024-? to
the users, and also why it is crucial to ensure that the test suite
exercises the related test cases. This commit ensures the latter.

In order to be a better Windows citizenship, Git should
save its configuration files on AppData folder. This can
enables git configuration files be replicated between machines
using the same Microsoft account logon which would reduce the
friction of setting up Git on new systems. Therefore, if
%APPDATA%\Git\config exists, we use it; otherwise
$HOME/.config/git/config is used.

Git LFS is now built with Go 1.21 which no longer supports Windows 7.
However, Git for Windows still wants to support Windows 7.

Ideally, Git LFS would re-introduce Windows 7 support until Git for
Windows drops support for Windows 7, but that's not going to happen:
git-for-windows#4996 (comment)

The next best thing we can do is to let the users know what is
happening, and how to get out of their fix, at least.

This is not quite as easy as it would first seem because programs
compiled with Go 1.21 or newer will simply throw an exception and fail
with an Access Violation on Windows 7.

The only way I found to address this is to replicate the logic from Go's
very own `version` command (which can determine the Go version with
which a given executable was built) to detect the situation, and in that
case offer a helpful error message.

This addresses git-for-windows#4996.

The sparse tree walk algorithm was created in d5d2e93 (revision:
implement sparse algorithm, 2019-01-16) and involves using the
mark_trees_uninteresting_sparse() method. This method takes a repository
and an oidset of tree IDs, some of which have the UNINTERESTING flag and
some of which do not.

Create a method that has an equivalent set of preconditions but uses a
"dense" walk (recursively visits all reachable trees, as long as they
have not previously been marked UNINTERESTING). This is an important
difference from mark_tree_uninteresting(), which short-circuits if the
given tree has the UNINTERESTING flag.

A use of this method will be added in a later change, with a condition
set whether the sparse or dense approach should be used.

While this command is definitely something we _want_, chances are that
upstreaming this will require substantial changes.

We still want to be able to experiment with this before that, to focus
on what we need out of this command: To assist with diagnosing issues
with large repositories, as well as to help monitoring the growth and
the associated painpoints of such repositories.

To that end, we are about to integrate this command into
`microsoft/git`, to get the tool into the hands of users who need it
most, with the idea to iterate in close collaboration between these
users and the developers familar with Git's internals.

However, we will definitely want to avoid letting anybody have the
impression that this command, its exact inner workings, as well as its
output format, are anywhere close to stable. To make that fact utterly
clear (and thereby protect the freedom to iterate and innovate freely
before upstreaming the command), let's mark its output as experimental
in all-caps, as the first thing we do.

In 245670c (credential-cache: check for windows specific errors, 2021-09-14)
we concluded that on Windows we would always encounter ENETDOWN where we
would expect ECONNREFUSED on POSIX systems, when connecting to unix sockets.
As reported in [1], we do encounter ECONNREFUSED on Windows if the
socket file doesn't exist, but the containing directory does and ENETDOWN if
neither exists. We should handle this case like we do on non-windows systems.

The reftable library goes out of its way to use its own set of allocator
functions that can be configured using `reftable_set_alloc()`. However,
Git does not configure this.

That is not typically a problem, except when Git uses a custom allocator
via some definitions in `git-compat-util.h`, as is the case in Git for
Windows (which switched away from the long-unmaintained nedmalloc to
mimalloc).

Then, it is quite possible that Git assigns a `strbuf` (allocated via
the custom allocator) to, say, the `refname` field of a
`reftable_log_record` in `write_transaction_table()`, and later on asks
the reftable library function `reftable_log_record_release()` to release
it, but that function was compiled without using `git-compat-util.h` and
hence calls regular `free()` (i.e. _not_ the custom allocator's own
function).

This has been a problem for a long time and it was a matter of some sort
of "luck" that 1) reftables are not commonly used on Windows, and 2)
mimalloc can often ignore gracefully when it is asked to release memory
that it has not allocated.

However, a recent update to `seen` brought this problem to the
forefront, letting t1460 fail in Git for Windows, with symptoms much in
the same way as the problem I had to address in d02c37c
(t-reftable-basics: allow for `malloc` to be `#define`d, 2025-01-08)
where exit code 127 was also produced in lieu of
`STATUS_HEAP_CORRUPTION` (C0000374) because exit codes are only 7 bits
wide.

It was not possible to figure out what change in particular caused these
new failures within a reasonable time frame, as there are too many
changes in `seen` that conflict with Git for Windows' patches, I had to
stop the investigation after spending four hours on it fruitlessly.

To verify that this patch fixes the issue, I avoided using mimalloc and
temporarily patched in a "custom allocator" that would more reliably
point out problems, like this:

I briefly considered contributing this "custom allocator" patch, too,
but it is unwieldy (for example, it would not work at all when compiling
with mimalloc support) and it would only waste space (or even time, if a
compile flag was introduced and exercised as part of the CI builds).
Given that it is highly unlikely that Git will lose the new
`reftable_set_alloc()` call by mistake, I rejected that idea as simply
too wasteful.

Every once in a while, whitespace errors are introduced in Git for
Windows' rebases to newer Git versions, simply by virtue of integrating
upstream commits that do not follow upstream Git's own whitespace rule.
In Git v2.50.0-rc0, for example, 03f2915 (xdiff: disable
cleanup_records heuristic with --minimal, 2025-04-29) introduced a
trailing space.

Arguably, non-actionable alerts are worse than no alerts at all, so
let's suppress those alerts that we cannot do anything about, anyway.

Continue the size_t evacuation around large object handling: with
deflate_it() and the locals around it widened, the
cast_size_t_to_ulong() shim the prior delta_delta() widening had to
leave behind in emit_binary_diff_body() goes away. deflate_it() is
file-static; the only callers are the two in emit_binary_diff_body()
already touched here.

emit_diff_symbol() formats the resulting sizes via uintmax_t / %"PRIuMAX",
so the diff output is not affected; only the per-process upper bound
on a binary patch chunk that this function can address grows beyond
4 GiB on Windows.

Prep for the upcoming read_blob_data_from_index() widening, whose
callers in convert.c feed the size they receive straight into these
two helpers. Both are file-static, so the change is contained.

path, where strbuf.len (size_t) was passed to a unsigned long
parameter.

Continue the size_t evacuation. read_blob_data_from_index() reads
the blob through the size_t odb_read_object() API but writes the
size back through an unsigned long out-parameter, silently
truncating anything past 4 GiB on Windows. Widen the out-parameter,
drop the cast_size_t_to_ulong() shim, and move the matching locals
in the two convert.c callers and the one in attr.c. Their
downstream consumers (gather_convert_stats() widened in the prior
commit and read_attr_from_buf() already size_t) take the new type
directly.

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.

…ITOR"

In e3f7e01 (Revert "editor: save and reset terminal after calling
EDITOR", 2021-11-22), we reverted the commit wholesale where the
terminal state would be saved and restored before/after calling an
editor.

The reverted commit was intended to fix a problem with Windows Terminal
where simply calling `vi` would cause problems afterwards.

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.

This should still catch the majority of the cases, and will bridge the
time until the original patch is re-done in a way that addresses all
concerns.

The `--stdin` option was a well-established paradigm in other commands,
therefore we implemented it in `git reset` for use by Visual Studio.

Unfortunately, upstream Git decided that it is time to introduce
`--pathspec-from-file` instead.

To keep backwards-compatibility for some grace period, we therefore
reinstate the `--stdin` option on top of the `--pathspec-from-file`
option, but mark it firmly as deprecated.

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.

Reintroduce the 'core.useBuiltinFSMonitor' config setting (originally added
in 0a756b2 (fsmonitor: config settings are repository-specific,
2021-03-05)) after its removal from the upstream version of FSMonitor.

Upstream, the 'core.useBuiltinFSMonitor' setting was rendered obsolete by
"overloading" the 'core.fsmonitor' setting to take a boolean value. 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.

Additionally, for this deprecation period, advise users to switch to using
'core.fsmonitor' to specify their use of the builtin FSMonitor.

This topic branch re-adds the deprecated --stdin/-z options to `git
reset`. Those patches were overridden by a different set of options in
the upstream Git project before we could propose `--stdin`.

We offered this in MinGit to applications that wanted a safer way to
pass lots of pathspecs to Git, and these applications will need to be
adjusted.

Instead of `--stdin`, `--pathspec-from-file=-` should be used, and
instead of `-z`, `--pathspec-file-nul`.

Upstream Git does not test their tags with the expensive set of tests,

Originally introduced as `core.useBuiltinFSMonitor` in Git for Windows
and developed, improved and stabilized there, the built-in FSMonitor
only made it into upstream Git (after unnecessarily long hemming and
hawing and throwing overly perfectionist style review sticks into the
spokes) as `core.fsmonitor = true`.

In Git for Windows, with this topic branch, we re-introduce the
now-obsolete config setting, with warnings suggesting to existing users
how to switch to the new config setting, with the intention to
ultimately drop the patch at some stage.

While upstreaming those patches, I've been asked to adjust them. This
backports those fixes.

Of course, the _real_ reason to do this _now_ is that I need _some_ PR
to make a new Git for Windows release (to address [the
NTLM](git-for-windows#6308) issue).
Mirror what git survey already reports: lightweight tags
(pointing straight at a commit/tree/blob) and annotated tags
(pointing at an OBJ_TAG that is itself stored as a separate
object) are different things in many monorepo contexts, and one
of the differences git survey users routinely care about. Add
an annotated_tags counter to struct ref_stats, populate it in
count_references() by peeking at the ref OID's object type, and
expose it as a sub-row under Tags in the table output and as
references.tags.annotated.count in the machine-readable formats.

Step toward pivoting the standalone git survey command onto
git repo structure; this fills the first of the four feature
gaps documented in the assessment.

Tests in t1901 widened to assert the new row and key.

`git repo structure` walks every reference enumerated by
`refs_for_each_ref()` and feeds each reference's tip into the path
walk that produces the object counts. There is no way to scope the
inquiry to a subset of refs, even though that is the most common
need when an operator is investigating what part of the history is
driving cost: only branches, only release tags, only one remote's
view, etc.

Add a single `--ref-filter=<pattern>` option that, when given,
restricts both the reference count and the object walk to refs whose
full name matches one of the patterns. The option is repeatable;
multiple patterns form a union, so `--ref-filter='refs/heads/*'
--ref-filter='refs/tags/v*'` includes local branches and tags whose
short name starts with `v`. Patterns use `wildmatch()` with
`WM_PATHNAME` semantics so a `*` does not cross `/`, matching the
convention used by `git for-each-ref` positional arguments.

Choosing a single flexible filter, rather than a proliferation of
per-kind flags like `--branches`, `--tags`, `--remotes`, keeps the
option surface small and lets the same mechanism express
narrow selections the per-kind flags could not, such as "only release
tags" (`'refs/tags/v*'`) or "only one remote's branches"
(`'refs/remotes/origin/*'`). Without `--ref-filter`, behaviour is
unchanged: every ref `refs_for_each_ref()` enumerates contributes.

Both the reference counter and the path-walk seeding (via
`add_pending_oid()`) sit on the same callback, so an early return
when no pattern matches naturally excludes a ref from both. No
separate object-walk machinery is needed.

Cover the two interesting code paths with tests in t1901: a single
filter narrowing to branches, and two filters unioning to include
both branches and tags.

`git survey` distinguishes itself from `git repo structure` largely by
its path-level reporting: in addition to whole-repo totals it lists the
paths whose object histories dominate the repository, ranked by raw
count, on-disk size, and inflated size, separately for trees and blobs.
That is often the most actionable output from `git survey`, since it
points an operator at the directories and files that should be reviewed
for cleanup, sparse-checkout exclusion, or rewriting.

`git repo structure` already drives the same path-walk traversal that
`git survey` uses to gather its per-path numbers; the callback simply
discards the path. Aggregate per-(path, type) summaries inside that
existing callback and add a bounded, descending-sorted "top-N" table
keyed by each of the three axes. Gate the feature behind a new
`--top=<n>` option, defaulting to 0, so unadorned invocations are
unaffected and pay no extra work for the top-N tracking.

Mirror the sort and eviction strategy from `builtin/survey.c`: keep an
array of at most N entries sorted from largest to smallest, walk it
from the bottom on each candidate, and shift entries down when a new
one belongs. Compared to `builtin/survey.c`, drop the void-pointer
indirection in the table data, type the comparator's arguments, and
fold the trivial comparators into the `(a > b) - (a < b)` idiom.

For the human-readable `table` output, extend the existing nested
bullet layout with two new top-level sections, `* Top trees` and
`* Top blobs`, each containing three sub-tables (`Top by count`,
`Top by disk size`, `Top by inflated size`). The path becomes the row
name and the relevant scalar becomes the value, reusing
`stats_table_count_addf` and `stats_table_size_addf` so units and
column alignment match the rest of the table.

For the `lines`/`nul` key-value formats, emit one
`objects.<type>.top.by_<axis>.<rank>.path=<path>` entry alongside an
`objects.<type>.top.by_<axis>.<rank>.<axis>=<value>` entry per ranked
path, so consumers can dispatch by axis without parsing the schema.
The root tree's path is the empty string as produced by the path-walk
machinery; preserve that as-is to stay faithful to the upstream
representation rather than fabricating a placeholder.

This is the first piece of folding `git survey`'s functionality into
`git repo structure`. Subsequent commits will add the corresponding
configuration knob and, eventually, turn `git survey` into a thin
deprecated shim over `git repo structure`.

The preceding commit added `--top=<n>` to `git repo structure`,
reporting the top-N paths per type ranked by count, on-disk size, and
inflated size. Cover the three behaviors that matter for that option:

  * Without `--top`, the key-value output emits no `top.*` keys, so
    existing parsers stay unaffected.

  * `--top=N` produces exactly N ranked entries on each of the six
    `objects.<type>.top.by_<axis>` axes (count/disk_size/inflated_size
    crossed with trees/blobs), and a constructed input where one blob
    is several orders of magnitude bigger than the other lets us
    assert the ordering on the disk-size and inflated-size axes.

  * A negative `--top` is rejected with a non-zero exit and a message
    naming the constraint, so a typo cannot silently degrade into the
    default zero.

Avoid grep patterns starting with `--`; grep would parse the leading
double dash as an option terminator.

`git survey` exposes its `--top` default via `survey.top` so that a
site or per-repository operator can switch the detail tables on once
and have every subsequent invocation include them. Mirror that
ergonomics for `git repo structure` so that, as `git survey`'s
functionality is folded into `git repo structure`, the configuration
side of the migration story stays equivalent.

Add a small `git_config_int` callback bound to `repo.structure.top`
and invoke it before `parse_options()`, so a `--top=<N>` on the
command line cleanly overrides the configured default (including
`--top=0` to opt out of the detail tables when configuration enables
them). Reject negative configured values with the same wording as the
command-line guard, since `git_config_int()` happily returns negative
integers.

Document the new variable in a fresh `Documentation/config/repo.adoc`
and wire it into the alphabetical includes in `Documentation/config.adoc`
between `repack.adoc` and `rerere.adoc`. Cover the precedence
behaviour with a t1901 test: a configured value enables the tables by
default, and a command-line `--top=0` suppresses them again.

Note that the reported paths respect the `core.quotePath` setting.

`git survey` started life as an experimental scale-measurement tool;
the preceding commits give `git repo structure` the path-level detail
tables and ref-scoping mechanism that were `git survey`'s main draw,
so the two now overlap substantially. Plan the migration explicitly:
add a short notice at the top of the description making clear which
of `git survey`'s knobs map to which `git repo structure` option, and
state that a future release will turn `git survey` into a thin shim
over `git repo structure`.

Putting the notice in the description (rather than only the synopsis)
ensures it shows up in `git help survey` rendering before the reader
sees any option specifics, so an operator skimming the page learns
about the replacement before adopting any survey-specific flags.

`git survey` was an experimental scale-measurement tool whose
distinctive features (ref-kind filters, top-N path tables) are now
all available in `git repo structure`. With the path-level reporting
in place (commits "repo: filter the structure scope via
--ref-filter=<pattern>" and "repo: report top-N paths by count, disk,
and inflated size in structure"), there is no functionality `git
survey` provides that `git repo structure` cannot.

Replace the 764-line `git survey` implementation with a roughly
hundred-line shim that:

  * Accepts the existing `git survey` command line so callers in
    scripts continue to parse without changes.
  * Emits a deprecation warning naming the replacement command, so
    interactive users learn about the migration target.
  * Translates the survey-specific knobs into the equivalent
    `git repo structure` invocation and re-execs the canonical
    command via `execv_git_cmd()`. Per-kind ref selectors fan out
    into the corresponding `refs/heads/*`, `refs/tags/*`, etc.
    `--ref-filter` patterns; `--top=<N>` is forwarded directly;
    `--all-refs` becomes the absence of any `--ref-filter`.

Two survey options have no `git repo structure` counterpart:
`--verbose` controlled per-step trace output the new command does
not emit, and `--detached` selected the detached HEAD which
`git repo structure` does not enumerate separately. Both are
silently accepted and produce a single warning each, so old
invocations keep working while the absence of these knobs in `git
repo structure` is made visible.

Rewrite t8100 to assert the shim's contract: the deprecation
warning is printed, the output is byte-identical to a corresponding
`git repo structure` invocation, and the per-kind selector
translation produces the right `--ref-filter` pattern. The
preceding survey-specific output assertions (the multi-column
plaintext tables) no longer apply, since `git repo structure`'s
output format is now the canonical one and is covered by t1901.

The `survey.*` configuration keys (`survey.top`, `survey.progress`,
`survey.verbose`) are no longer honored by the shim. They were
mirrored by the preceding `repo.structure.top` work for the most
useful knob; users with `survey.top` set in config should migrate
to `repo.structure.top`. This is a backward-incompatible removal
documented by the deprecation notice in `git-survey.adoc`.

Git for Windows dropped Windows 7 support a long time ago. This patch

exclusively to support Windows 7 users. Therefore it can now go enjoy

…it-for-windows#6268)

`git survey` was always experimental, and I never got around to
upstreaming it to make it non-experimental.

In the meantime, the `git repo structure` command was upstreamed
upstream, which covers most of the same ground with a cleaner option
surface and a stable output contract. This PR closes the remaining gap
(annotated-tag breakdown, ref scoping, top-N paths by
count/disk/inflated, and the corresponding configuration knob) and then
turns `git survey` into a thin shim that warns about deprecation,
translates its old command line into the equivalent `git repo structure`
invocation, and re-execs the canonical command. Net result: one
user-facing tool to maintain and to teach instead of two.

The intent is that scripts pinned to `git survey` keep working (a
warning aside), and that operators have a single answer when they ask
"how do I see what's making my repository large?". The `survey.*`
configuration keys are intentionally dropped; the only one that
mattered, `survey.top`, has a direct replacement in
`repo.structure.top`.
Git for Windows dropped Windows 7 support a long time ago.

There is a patch (introduced in
git-for-windows#5042 and in git-for-windows#5059) to detect
when Git LFS failed to start because of lack of Windows 7 support (which
was lost somewhat surprisingly, via a Go upgrade that slipped that
change in), and to provid a helpful message to the user in that
instance.

Since Git for Windows itself does not support Windows 7 anymore, that
patch is no longer necessary, either.
