With the previous commit removing every opt-in, the build-system
plumbing for nedmalloc has nothing left to switch on. Remove it so
that the upcoming deletion of the compat/nedmalloc/ tree is a pure
file removal.

The vendored nedmalloc allocator under compat/nedmalloc/ has been
unmaintained upstream for a very long time: the original repository at
https://github.com/ned14/nedmalloc received its last commit on July 5,
2014, and was archived (made read-only) by its owner on March 15, 2019.
Our copy has been carried forward unchanged ever since.
The Git for Windows commit that introduced mimalloc as a replacement
on Windows ("mingw: use mimalloc", 2019-06-24, present in the Git for
Windows branch thicket but not upstream) already observed at that time
that nedmalloc had ceased to see any updates for several years.
This came to a head when the Git for Windows SDK upgraded to GCC 16:
the `add_segment()` function in `compat/nedmalloc/malloc.c.h` declares
`int nfences = 0` and only references it inside an `assert()`, which
GCC 16 now flags as `-Wunused-but-set-variable`. Combined with the
`-Werror` enabled by `DEVELOPER=1`, this turns into a hard build
failure:
compat/nedmalloc/malloc.c.h: In function 'add_segment':
compat/nedmalloc/malloc.c.h:3897:7: error: variable 'nfences' set but not used [-Werror=unused-but-set-variable=]
3897 | int nfences = 0;
| ^~~~~~~
cc1.exe: all warnings being treated as errors
The same source built without complaint under GCC 15.2.0; the
regression was bisected to the SDK package update at
https://github.com/git-for-windows/git-sdk-64/commit/188d93dd455
(`mingw-w64-x86_64-gcc 15.2.0-14 -> 16.1.0-1`), with the failing CI
run captured at
https://github.com/git-for-windows/git-sdk-64/actions/runs/25244795074.
Rather than patch the unmaintained vendored sources to silence the
warning, stop opting into nedmalloc altogether on Windows. The
platform allocator is what every non-MINGW build already uses, and a
fresh build of git.git's master against a minimal Git for Windows SDK
upgraded to GCC 16 completes successfully.
The compat/nedmalloc/ subtree itself is removed by subsequent commits
in this series.

The doc `technical/commit-graph.adoc` says that replace objects and
commit grafts turn off commit-graph:
Commit grafts and replace objects can change the shape of the commit
history. The latter can also be enabled/disabled on the fly using
`--no-replace-objects`. This leads to difficulty storing both possible
interpretations of a commit id, especially when computing generation
numbers. The commit-graph will not be read or written when
replace-objects or grafts are present.
But this isn’t mentioned in the user-facing doc. Let’s mention it on
git-replace(1) and git-commit-graph(1).

As is done for all the other maintenance tasks, let's release the ODB
also before starting the geometric repacking. That way, the `.idx` files
won't be `mmap()`ed when they are to be deleted (which does not work on
Windows because you cannot delete files on that platform as long as they
are kept open by a process).
This regression was introduced by 9bc151850c1c (builtin/maintenance:
introduce "geometric-repack" task, 2025-10-24), but was only noticed
once geometric repacking was made the default in 452b12c2e0fe (builtin/
maintenance: use "geometric" strategy by default, 2026-02-24).
The fix recapitulates my work from df76ee7b77f0 (run-command: offer to
close the object store before running, 2021-09-09) & friends.
To guard against future regressions of this kind, add a check to
`run_and_verify_geometric_pack()` in `t7900` that detects orphaned
`.idx` files left behind after repacking. Contrary to interactive
calls, the `git maintenance` call in that test case would _not_ block on
Windows, asking whether to retry deleting that file, which is the reason
why this bug was not caught earlier.
Furthermore, since the default behavior of `DeleteFileW()` was changed
at some point between Windows 10 Build 17134.1304 and Build 18363.657
to use POSIX semantics (see https://stackoverflow.com/a/60512798),
the added orphaned-`.idx` check would be insufficient to catch this
regression on modern Windows without emulating legacy delete semantics
via `GIT_TEST_LEGACY_DELETE=1`.
This fixes https://github.com/git-for-windows/git/issues/6210.

At some point between Windows 10 Build 17134.1304 and Build 18363.657,
the default behavior of `DeleteFileW()` was changed to use POSIX
semantics (https://stackoverflow.com/a/60512798). Under those semantics,
a file can be deleted even when another process holds an active
`MapViewOfFile` view on it: the directory entry is removed immediately,
but the underlying data persists until the last handle is closed.
On older Windows versions (and Windows 10 builds before that change),
`DeleteFileW()` uses legacy semantics where deletion fails outright if
any process holds a file mapping.
To allow testing code paths that depend on the legacy behavior, introduce
a `GIT_TEST_LEGACY_DELETE` environment variable. When set, `mingw_unlink()`
uses `SetFileInformationByHandle()` with `FileDispositionInfo` (the
non-POSIX variant) instead of `DeleteFileW()`, forcing legacy delete
semantics regardless of the Windows version.

Test git URL parsing, validation and component extraction
on all documented git URL schemes and syntaxes.
Add IPv6 host coverage in URL form:
ssh://[::1]/path
ssh://user@[::1]:1234/path
git://[::1]:9418/path
http://[2001:db8::1]/path
https://[2001:db8::1]/path
In URL form the brackets are kept in the host component (RFC 3986
syntax for IPv6 literals).
Also exercise the bracketed scp short forms that t5601-clone.sh
covers via parse_connect_url:
[host]:path
[host:port]:path
[::1]:repo
user@[::1]:repo
user@[host:port]:path
In scp form, brackets are kept for IPv6 literals (two or more inner
colons) and stripped for plain hostnames or host:port pairs.

Git commands can accept a rather wide variety of URLs syntaxes.
The range of accepted inputs might expand even more in the future.
This makes the parsing of URL components difficult since standard URL
parsers cannot be used. Extracting the components of a git URL would
require implementing all the schemes that git itself supports, not to
mention tracking its development continuously in case new URL schemes
are added.
The url-parse builtin command is designed to solve this problem
by exposing git's native URL parsing facilities as a plumbing command.
Other programs can then call upon git itself to parse the git URLs
and extract their components. This should be quite useful for scripts.

Define url_parse, a general parsing function that supports all Git URLs
including scp style URLs such as hostname:~user/repo.
It is adapted from the algorithm in connect.c's parse_connect_url
and reuses the shared enum url_scheme and url_get_scheme function
that previous commits made available in url.h. The new parser and
the connect path agree on scheme classification. url_parse has the
same interface as url_normalize and uses the same data structures.
Both functions accept the same URL forms with one deliberate
exception. Bare local paths such as "/abs/path", "./rel"
or "repo" are accepted by parse_connect_url as URL_SCHEME_LOCAL,
but rejected by url_parse because url_normalize requires a URL
with a scheme://host form. A consumer that wants to handle both
URLs and local paths needs to dispatch on url_is_local_not_ssh
before calling url_parse, just as the connect path does internally.
The duplication with parse_connect_url is intentional.
The two functions have different contracts:
- parse_connect_url
Calls die() on an unknown scheme
and returns NUL-terminated host/path
strings for the connect path
- url_parse
Returns NULL on failure while populating
out_info->err, and exposes components
as offset/length pairs into the normalized
URL buffer, matching url_normalize.
Reconciling both is possible, but not in the scope
of the current patch set.

Enumerate a URL_SCHEME_UNKNOWN result with value 0.
Have url_get_scheme() return it for unrecognized
schemes instead of calling die() itself.
Move the die() call to parse_connect_url()
where url_get_scheme() is used.
This lets url_get_scheme() be used from contexts

the program. For example, a future plumbing command
that validates URLs.
No external behavior change. parse_connect_url() still dies

RFC 1738 names the part of a URL before the colon a "scheme".
connect.c calls it "protocol", which is more generic
and collides with the unrelated enum protocol_version.
Rename:
enum protocol -> enum url_scheme
PROTO_* -> URL_SCHEME_*
prot_name -> url_scheme_name
get_protocol -> url_get_scheme
The local variables in parse_connect_url and git_connect
are renamed accordingly, from protocol to scheme.
No behavior change. The user-visible diagnostics
and translated error messages are preserved:
"Diag: protocol=..."
"protocol '%s' is not supported"
"unknown protocol"
This rename also prepares for moving the scheme-detection functions
to a shared header so that a future plumbing command can parse URLs
using the same logic as the connect path.

An explicit proxy URL with an unrecognized scheme such as
htpp://127.0.0.1 is currently accepted.
Git parses the URL, extracts the host part, and then passes only that
host to libcurl. Because no proxy type is selected for the unknown
scheme, Git leaves libcurl at its default HTTP proxy type, so the typo
is silently treated as an HTTP proxy.
Reject proxy URLs with explicit unsupported schemes instead of silently
accepting them. Keep the existing host:port-without-scheme behavior
unchanged.
Implement the SOCKS proxy handling with a shared table-driven mapping.
Add a regression test to cover the unsupported-scheme case.

The reference backends peel tag objects when storing references to them.
This is to provide optimized reads which avoids hitting the odb. The
previous commits ensures that the peeled value is now propagated via the
generic layer. So modify the packed and reftable backend to directly use
this value instead of calling `peel_object()` independently.

Certain reference backends {packed, reftable}, have the ability to also
store the peeled object ID for a reference pointing to a tag object.
This has the added benefit that during retrieval of such references, we
also obtain the peeled object ID without having to use the ODB.
To provide this functionality, each backend independently calls the ODB
to obtain the peeled OID. To move this functionality to the generic
layer, there must be support infrastructure to pass in a peeled OID for
reference updates.
Add a `peeled` field to the `ref_update` structure and modify
`ref_transaction_add_update()` to receive and copy this object ID to the
`ref_update` structure. Finally, modify `ref_transaction_update()` to
peel tag objects and pass the peeled OID to
`ref_transaction_add_update()`.
Update all callers of these functions with the new function parameters.
Callers which only add reflog updates, need to only pass in NULL, since
for reflogs, we don't store peeled OIDs. Reference deletions also only
need to pass in NULL. For others, pass along the peeled OID if
available.
In a following commit, we'll modify the backends to use this peeled OID
instead of parsing it themselves.

Regular reference updates made via reference transactions validate that
the provided object ID exists in the object database, which is done by
calling 'parse_object()'. This check is done independently by the
backends which leads to duplicated logic.
Let's move this to the generic layer, ensuring the backends only have to
care about reference storage and not about validation of the object IDs.
With this also remove the 'REF_TRANSACTION_ERROR_INVALID_NEW_VALUE'
error type as its no longer used.
Since we don't iterate over individual references in
`ref_transaction_prepare()`, we add this check to
`ref_transaction_update()`. This means that the validation is done as
soon as an update is queued, without needing to prepare the
transaction. It can be argued that this is more ideal, since this
validation has no dependency on the reference transaction being
prepared.
It must be noted that the change in behavior means that this error
cannot be ignored even with usage of batched updates, since this happens
when the update is being added to the transaction. But since the caller
gets specific error codes, they can either abort the transaction or
continue adding other updates to the transaction.
Modify 'builtin/receive-pack.c' to now capture the error type so that
the error propagated to the client stays the same. Also remove two of
the tests which validates batch-updates with invalid new_oid.

When using git-update-ref(1) with the '--batch-updates' flag, updates
rejected by the reference backend are displayed to the user while other
updates are applied. This only applies during the commit phase of the
transaction.
In the following commits, we'll also extend `ref_transaction_update()`
to reject updates before a transaction is prepared/committed. In
preparation, modify the code in update-ref to also handle non-generic
rejections from `ref_transaction_update()`. This involves propagating
information to each of the commands on whether updates are allowed to be
rejected, and also checking for rejections and only dying for generic
failures.
Errors encountered during updates will be shown to the user immediately
unlike other errors encountered only when the transaction is
prepared/committed. As the verification of object IDs and peeled tag
objects will move into `ref_transaction_update()` in the following
commit, this means that those errors will be shown to the user before
other errors, this changes the order of errors, but the functionality
remains the same.

given reference transactions. In the following commit, we'll add more
validation to this function. As such, it would be beneficial if the

between different errors.
To facilitate this, return `enum ref_transaction_error` from the

'REF_TRANSACTION_ERROR_GENERIC'. Since this retains the existing
behavior, no changes are made to any of the callers but this sets the
necessary infrastructure for introduction of other errors.

This allows easier extension of providing further options to the

`git fetch` accepts a remote group name (configured via `remotes.<name>`
in config) and fetches from each member remote. `git push` has no
equivalent — it only accepts a single remote name.
Teach `git push` to resolve its repository argument through
`add_remote_or_group()`, which was made public in the previous patch,
so that a user can push to all remotes in a group with:
git push <group>
When the argument resolves to a single remote, the behaviour is
identical to before. When it resolves to a group, each member remote
is pushed in sequence.
The group push path rebuilds the refspec list (`rs`) from scratch for
each member remote so that per-remote push mappings configured via
`remote.<name>.push` are resolved correctly against each specific
remote. Without this, refspec entries would accumulate across iterations
and each subsequent remote would receive a growing list of duplicated
entries.
Mirror detection (`remote->mirror`) is also evaluated per remote using
a copy of the flags, so that a mirror remote in the group cannot set
TRANSPORT_PUSH_FORCE on subsequent non-mirror remotes in the same group.

The existing description of http.emptyAuth explains the purpose of the
setting but never says what values it accepts. Readers have to infer
from context (or read the source) that it takes 'true', 'false', or
'auto', and what each one means.
Document the three accepted values explicitly:
* 'auto' (the default) only sends empty credentials when the server's
401 response advertises a mechanism that requires them, such as
GSS-Negotiate. This matches the long-standing auto-detection
behaviour added in 40a18fc77c (http: add an "auto" mode for
http.emptyauth, 2017-02-25).
* 'true' unconditionally sends empty credentials on the very first
request, before any 401 response, for callers that know they want
this behaviour up front.
* 'false' disables the feature entirely; mechanisms that depend on
empty credentials, such as GSS-Negotiate, will not work in this
mode.

The l10n workflow uses `mshick/add-pr-comment` to post git-po-helper
reports as comments on translation pull requests. It was still pinned
to v2, which runs on Node.js 20. GitHub is phasing out the Node.js 20
runtime on Actions runners, so staying on v2 will eventually cause the
"Create comment in pull request for report" step to fail.
The sole breaking change in v3 is the switch from Node.js 20 to
Node.js 24 (https://github.com/mshick/add-pr-comment/releases/tag/v3.0.0).
The action's inputs and outputs are unchanged, so the upgrade is a
drop-in replacement. Subsequent v3.x releases added new opt-in
features (message truncation, retry with exponential backoff, file
attachments, commit comment support, "delete on status") but none of
them affect existing callers that do not opt in.

The v1 of `git-for-windows/setup-git-for-windows-sdk` runs on
Node.js 20, which GitHub is phasing out of the Actions runners.
v2 moves the action to Node.js 24 so that the CI jobs relying on

The risk is very low: v2 contains no functional changes to the
SDK setup itself, only the runtime upgrade. The action still
provisions the same minimal SDK and exposes the same outputs.
The sole precondition is a recent Actions Runner (>= 2.327.1),
which the github.com-hosted runners already satisfy.

Every workflow currently pins `actions/checkout` to v5, which was
introduced primarily to move to the Node.js 24 runtime. v6 is the
next release and worth picking up so we stay on a maintained version
of the action.
The one behaviorally interesting change in v6:
`persist-credentials` now stores the helper credentials under
`$RUNNER_TEMP` instead of writing them directly into the local
`.git/config`. Two implications follow:
1. In the normal case this is an unambiguous improvement -- the
token no longer lands in `.git/config`, reducing the risk of
inadvertently leaking it through workspace archiving
(`upload-artifact` snapshots, cache entries, core dumps, ...).
2. Docker container actions require an Actions Runner of at least
v2.329.0 to find the credentials in their new location. The
github.com-hosted runners our CI uses are already past that
version, so this does not affect us. Downstream users running
self-hosted runners may need to update them before adopting
this version of the action.
Risk analysis: our checkout steps either check out the default
repository (no special credential requirements) or, in the `vs-build`
job, explicitly set `repository: microsoft/vcpkg` and
`path: compat/vcbuild/vcpkg`. Neither case relies on the precise
location of the persisted credentials -- subsequent steps interact
with the API via the runner-provided `GITHUB_TOKEN` directly -- so
the v6 credential-storage change is transparent to our workflows.
The diff is purely the `@vN` identifier; there are no input or
output changes.

The only use we have of `actions/github-script` is the "skip if the
commit or tree was already tested" step in `main.yml`, which checks
whether an identical tree-SHA was already built successfully. It
currently pins v8; v9 is the latest release.
What v9 changes:
- The `ACTIONS_ORCHESTRATION_ID` environment variable is now
appended to the HTTP user-agent string. This is transparent to
our script.
- A new injected `getOctokit` factory lets scripts create
additional authenticated clients in the same step without
importing `@actions/github`. We do not use it.
- Two breaking changes affect scripts that either call
`require('@actions/github')` (fails at runtime, because
`@actions/github` v9 is now ESM-only) or that shadow the
implicit `getOctokit` parameter via `const`/`let` (syntax
error). Our script does neither -- it only uses the pre-supplied
`github` REST client and `core` helpers -- so the upgrade is
safe.
Risk analysis: the step is advisory. It sets `enabled=' but skip'`
as an optimization to avoid re-running CI on a tree that was already
tested successfully. Even if the v9 upgrade broke the script, the
surrounding `try { ... } catch (e) { core.warning(e); }` block would
degrade it to a warning and CI would still run normally. In practice
the script continues to work identically on v9.

`actions/upload-artifact` and `actions/download-artifact` are tightly
coupled: the upload action writes artifact archives in a format that
the download action then reads. Because of this coupling, the two
actions should always be bumped together so that the artifact format
contract between them is satisfied.
All of our `actions/upload-artifact` uses are still on v5, with one
stray v4 occurrence. Keeping them on these versions would leave the
artifact-upload steps running on Node.js 20, which GitHub is phasing
out, and would eventually cause all upload steps to fail.
Going from v5 directly to v7 folds in two release bumps:
- v6 switches the action's default runtime from Node.js 20 to
Node.js 24 (v5 had preliminary Node 24 support but still defaulted
to Node 20). This is the main motivation for bumping now: it gets
us off the deprecated runtime.
- v7 adds two opt-in features: direct (unzipped) single-file uploads
via a new `archive: false` parameter, and an internal conversion of
the action to ESM to match the updated `@actions/*` packages.
Risk analysis: we never pass `archive`, so the zip-as-usual behavior
is unchanged. We also do not `require('@actions/*')` from any calling
workflow, so the ESM migration cannot affect us. The upload steps we
care about -- tracked files/build artifacts and failing-test
directories -- keep the same inputs (`name`, `path`) and outputs, so
the diff is purely the `@vN` identifier. The main precondition is a
recent Actions Runner (>= 2.327.1), which the github.com-hosted
runners used by our CI already satisfy.
While at it, align the one remaining `@v4` occurrence with the rest
so that every `upload-artifact` step uses the same version.

We use `actions/download-artifact` to pass build artifacts between
the "windows-build" / "vs-build" / "windows-meson-build" jobs and
their corresponding test jobs. All callers are currently on v6;
bumping to v8 keeps this action in lockstep with the `upload-artifact`
bump above.
What v7 and v8 change:
- v7 switches the default runtime from Node.js 20 to Node.js 24 (v6
had preliminary Node 24 support but still defaulted to Node 20).
This is the main motivation: it gets us off the deprecated runtime.
- v8 makes three further changes:
* The package is converted to ESM (invisible to workflow authors).
* The action now checks the `Content-Type` header before
attempting to unzip a download, so that directly-uploaded
(unzipped) artifacts from `upload-artifact` v7 are downloaded
correctly.
* The `digest-mismatch` behaviour is changed from warn-and-
continue to a hard failure by default.
Risk analysis: defaulting hash-mismatch to a hard failure is
strictly safer than the previous warn-and-continue behaviour -- a
mismatch points to real corruption or tampering and should stop the
run. We download archives that the same workflow just uploaded, on
the same runner fleet, so false positives are not expected. Our
usage is limited to the `name` and `path` inputs, which are
unchanged between v6 and v8, so the diff is purely the `@vN`
identifier.

The v2 of `microsoft/setup-msbuild` runs on Node.js 20, which GitHub
is phasing out of the Actions runners. v3 is a minimal release whose
only substantive change is moving the action's runtime to Node.js 24,
so that our Visual Studio build jobs keep working once Node.js 20 is
removed from the runners.
The risk of this bump is very low: v3 contains no functional changes
to the action itself -- it merely adds `msbuild.exe` to `PATH`, with
no change to command-line flags, inputs, outputs, or default tool
resolution. The only precondition is a recent-enough Actions Runner,
which the github.com-hosted runners already satisfy.

When switching branches with "git checkout -m", the attempted merge
of local modifications may cause conflicts with the changes made on
the other branch, which the user may not want to (or may not be able
to) resolve right now. Because there is no easy way to recover from
this situation, we discouraged users from using "checkout -m" unless
they are certain their changes are trivial and within their ability
to resolve conflicts.
Teach the -m flow to create a temporary stash before switching and
reapply it after. On success, the stash is silently applied and
the list of locally modified paths is shown, same as a successful
"git checkout" without "-m".
If reapplying causes conflicts, the stash is kept and the user is
told they can resolve and run "git stash drop", or run "git reset
--hard" and later "git stash pop" to recover their changes.

merge_working_tree() acquires the index lock via
repo_hold_locked_index() but several early return paths exit
without calling rollback_lock_file(), leaving the lock held.
While this is currently harmless because the process exits soon
after, it becomes a problem if the function is ever called more
than once in the same process.
Add rollback_lock_file() calls to all early return paths.
