When FSCache is active, we can cache the reparse tag and use it directly
to determine whether a path refers to an NTFS junction, without any
additional, costly I/O.

will make use of the FSCache in `git clean` (contingent on
`core.fscache` set, of course).

Using FindFirstFileExW() requires the OS to allocate a 64K buffer for each
directory and then free it when we call FindClose(). Update fscache to call
the underlying kernel API NtQueryDirectoryFile so that we can do the buffer
management ourselves. That allows us to allocate a single buffer for the
lifetime of the cache and reuse it for each directory.
This change improves performance of 'git status' by 18% in a repo with ~200K
files and 30k folders.
Documentation for NtQueryDirectoryFile can be found at:
https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/content/ntifs/nf-ntifs-ntquerydirectoryfilehttps://docs.microsoft.com/en-us/windows/desktop/FileIO/file-attribute-constantshttps://docs.microsoft.com/en-us/windows/desktop/fileio/reparse-point-tags
To determine if the specified directory is a symbolic link, inspect the
FileAttributes member to see if the FILE_ATTRIBUTE_REPARSE_POINT flag is
set. If so, EaSize will contain the reparse tag (this is a so far
undocumented feature, but confirmed by the NTFS developers). To
determine if the reparse point is a symbolic link (and not some other
form of reparse point), test whether the tag value equals the value
IO_REPARSE_TAG_SYMLINK.
The NtQueryDirectoryFile() call works best (and on Windows 8.1 and
earlier, it works *only*) with buffer sizes up to 64kB. Which is 32k
wide characters, so let's use that as our buffer size.

The threading model for fscache has been to have a single, global cache.
This puts requirements on it to be thread safe so that callers like
preload-index can call it from multiple threads. This was implemented
with a single mutex and completion events which introduces contention
between the calling threads.
Simplify the threading model by making fscache thread specific. This allows
us to remove the global mutex and synchronization events entirely and instead
associate a fscache with every thread that requests one. This works well with
the current multi-threading which divides the cache entries into blocks with
a separate thread processing each block.
At the end of each worker thread, if there is a fscache on the primary
thread, merge the cached results from the worker into the primary thread
cache. This enables us to reuse the cache later especially when scanning for
untracked files.
In testing, this reduced the time spent in preload_index() by about 25% and
also reduced the CPU utilization significantly. On a repo with ~200K files,
it reduced overall status times by ~12%.

When updating the skip-worktree bits in the index to align with new
values in a sparse-checkout file, Git scans the entire working
directory with lstat() calls. In a sparse-checkout, many of these
lstat() calls are for paths that do not exist.
Enable the fscache feature during this scan. Since enable_fscache()
calls nest, the disable_fscache() method decrements a counter and
would only clear the cache if that counter reaches zero.
In a local test of a repo with ~2.2 million paths, updating the index

Fix regression described in:
https://github.com/git-for-windows/git/issues/1392
which was introduced in:
b2353379bb
Problem Symptoms
================
When the user has a .gitignore file that is a symlink, the fscache
optimization introduced above caused the stat-data from the symlink,
rather that of the target file, to be returned. Later when the ignore
file was read, the buffer length did not match the stat.st_size field
and we called die("cannot use <path> as an exclude file")
Optimization Rationale
======================
The above optimization calls lstat() before open() primarily to ask
fscache if the file exists. It gets the current stat-data as a side
effect essentially for free (since we already have it in memory).
If the file does not exist, it does not need to call open(). And
since very few directories have .gitignore files, we can greatly
reduce time spent in the filesystem.
Discussion of Fix
=================
The above optimization calls lstat() rather than stat() because the
fscache only intercepts lstat() calls. Calls to stat() stay directed
to the mingw_stat() completly bypassing fscache. Furthermore, calls
to mingw_stat() always call {open, fstat, close} so that symlinks are
properly dereferenced, which adds *additional* open/close calls on top
of what the original code in dir.c is doing.
Since the problem only manifests for symlinks, we add code to overwrite
the stat-data when the path is a symlink. This preserves the effect of
the performance gains provided by the fscache in the normal case.

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.

Teach "add" to use preload-index and fscache features
to improve performance on very large repositories.
During an "add", a call is made to run_diff_files()
which calls check_remove() for each index-entry. This
calls lstat(). On Windows, the fscache code intercepts
the lstat() calls and builds a private cache using the
FindFirst/FindNext routines, which are much faster.
Somewhat independent of this, is the preload-index code
which distributes some of the start-up costs across
multiple threads.
We need to keep the call to read_cache() before parsing the
pathspecs (and hence cannot use the pathspecs to limit any preload)
because parse_pathspec() is using the index to determine whether a
pathspec is, in fact, in a submodule. If we would not read the index
first, parse_pathspec() would not error out on a path that is inside
a submodule, and t7400-submodule-basic.sh would fail with
not ok 47 - do not add files from a submodule
We still want the nice preload performance boost, though, so we simply
call read_cache_preload(&pathspecs) after parsing the pathspecs.

Teach FSCACHE to remember "not found" directories.
This is a performance optimization.
FSCACHE is a performance optimization available for Windows. It
intercepts Posix-style lstat() calls into an in-memory directory
using FindFirst/FindNext. It improves performance on Windows by
catching the first lstat() call in a directory, using FindFirst/
FindNext to read the list of files (and attribute data) for the
entire directory into the cache, and short-cut subsequent lstat()
calls in the same directory. This gives a major performance
boost on Windows.
However, it does not remember "not found" directories. When STATUS
runs and there are missing directories, the lstat() interception
fails to find the parent directory and simply return ENOENT for the
file -- it does not remember that the FindFirst on the directory
failed. Thus subsequent lstat() calls in the same directory, each
re-attempt the FindFirst. This completely defeats any performance
gains.
This can be seen by doing a sparse-checkout on a large repo and
then doing a read-tree to reset the skip-worktree bits and then
running status.
This change reduced status times for my very large repo by 60%.

If multiple threads access a directory that is not yet in the cache, the

On cache miss, add a future object to the cache to indicate that the

Checking the work tree status is quite slow on Windows, due to slow
`lstat()` emulation (git calls `lstat()` once for each file in the
index). Windows operating system APIs seem to be much better at scanning
the status of entire directories than checking single files.
Add an `lstat()` implementation that uses a cache for lstat data. Cache
misses read the entire parent directory and add it to the cache.
Subsequent `lstat()` calls for the same directory are served directly
from the cache.
Also implement `opendir()`/`readdir()`/`closedir()` so that they create
and use directory listings in the cache.
The cache doesn't track file system changes and doesn't plug into any
modifying file APIs, so it has to be explicitly enabled for git functions
that don't modify the working copy.
Note: in an earlier version of this patch, the cache was always active and
tracked file system changes via ReadDirectoryChangesW. However, this was
much more complex and had negative impact on the performance of modifying
git commands such as 'git checkout'.

Git v2.53.0-rc0 included f406b895529 (Merge branch

Windows. While this merge was reverted for independent reasons in

This introduces `git survey` to Git for Windows ahead of upstream for
the express purpose of getting the path-based analysis in the hands of
more folks.
The inspiration of this builtin is
[`git-sizer`](https://github.com/github/git-sizer), but since that
command relies on `git cat-file --batch` to get the contents of objects,
it has limits to how much information it can provide.
This is mostly a rewrite of the `git survey` builtin that was introduced
into the `microsoft/git` fork in microsoft/git#667. That version had a
lot more bells and whistles, including an analysis much closer to what
`git-sizer` provides.
The biggest difference in this version is that this one is focused on
using the path-walk API in order to visit batches of objects based on a
common path. This allows identifying, for instance, the path that is
contributing the most to the on-disk size across all versions at that
path.
For example, here are the top ten paths contributing to my local Git
repository (which includes `microsoft/git` and `gitster/git`):

This is a follow up to #5157 as well as motivated by the RFC in
gitgitgadget/git#1786.
We have ways of walking all objects, but it is focused on visiting a
single commit and then expanding the new trees and blobs reachable from
that commit that have not been visited yet. This means that objects
arrive without any locality based on their path.
Add a new "path walk API" that focuses on walking objects in batches
according to their type and path. This will walk all annotated tags, all
commits, all root trees, and then start a depth-first search among all
paths in the repo to collect trees and blobs in batches.
The most important application for this is being fast-tracked to Git for
Windows: `git pack-objects --path-walk`. This application of the path
walk API discovers the objects to pack via this batched walk, and
automatically groups objects that appear at a common path so they can be
checked for delta comparisons.
This use completely avoids any name-hash collisions (even the collisions
that sometimes occur with the new `--full-name-hash` option) and can be
much faster to compute since the first pass of delta calculations does
not waste time on objects that are unlikely to be diffable.
Some statistics are available in the commit messages.
This is an updated version of gitgitgadget/git#1785, intended for early
consumption into Git for Windows.
The idea here is to add a new `--full-name-hash` option to `git
pack-objects` and `git repack`. This adjusts the name-hash value used
for finding delta bases in such a way that uses the full path name with
a lower likelihood of collisions than the default name-hash algorithm.
In many repositories with name-hash collisions and many versions of
those paths, this can significantly reduce the size of a full repack. It
can also help in certain cases of `git push`, but only if the pack is
already artificially inflated by name-hash collisions; cases that find
"sibling" deltas as better choices become worse with `--full-name-hash`.
Thus, this option is currently recommended for full repacks of large
repos, and on client machines without reachability bitmaps.
Some care is taken to ignore this option when using bitmaps, either
writing bitmaps or using a bitmap walk during reads. The bitmap file
format contains name-hash values, but no way to indicate which function
is used, so compatibility is a concern for bitmaps. Future work could
explore this idea.
After this PR is merged, then the more-involved `--path-walk` option may
be considered.

v2.45.1 but not into Git v2.45.1 (because the latter does not come with
symlink support on Windows).

This patch adds a GitHub workflow (to be triggered manually) to allow
for conveniently verifying that Git and Scalar still work as intended in
Windows Nano Server (a relatively small container base image that is
frequently used where a "small Windows" is needed, e.g. in automation
;-))
