Setting branch.<name>.deleteMerged=false exempts that branch from
"git branch --delete-merged", which is useful for a topic you want
to keep developing after an early round of it has been merged
upstream. Unless --quiet is given, each skip is reported so the
user knows why their topic was kept.
Explicit deletion with "git branch -d" still uses the normal merge

git branch (--delete-merged <branch>)... [<pattern>...]
deletes local branches matching the optional patterns when their
configured upstream matches one of the --delete-merged arguments and
their tip is reachable from that upstream. The work has already landed
on the upstream they track, so the local copy is no longer needed.
The option can be repeated to widen the upstream match. Keeping the
candidate patterns as positional arguments lets users bound the set of
local branches that may be deleted independently of the upstream
selection.
A branch is not deleted when:
* it is checked out in any worktree
* its configured upstream ref no longer exists, since a missing
upstream is not by itself a sign of integration
* pushing it by name to the remote configured by
branch.<name>.remote would update its upstream, as determined by
mapping the branch ref through that remote's fetch refspec. For
example, a local "main" that tracks "origin/main" is kept even when
remote.pushDefault names a fork. Right after a pull it merely looks
fully merged.
A branch whose work is not yet merged into its upstream is silently
skipped, so one unmerged topic does not abort the whole sweep.
A branch that a surviving branch depends on through a chain of local
upstreams is also kept, so no branch is deleted out from under stacked
work. Collect this transitive set without changing the candidate set
during ref iteration: walk upstream chains from surviving branches,
visit each branch at most once, and remove the collected bases only
after the iteration completes. This makes the result independent of
ref iteration order without repeated full scans.

Add a --forked option to "git branch" list mode that lists only
branches whose configured upstream matches <branch>. The argument
can be a ref (e.g. "origin/main", "master"), a remote name like
"origin" for the branch its origin/HEAD points at, or a shell glob
(e.g. "origin/*"), and may be repeated to widen the filter.
It is an ordinary list filter, so it combines with the others:
git branch --merged origin/main --forked 'origin/*'
lists branches forked from origin that are already merged into
origin/main, and --no-merged inverts the question.
This is the building block for --delete-merged, which deletes the
listed branches once they have landed on their upstream.

Since the info command in cat-file --batch-command prints object
info for a given object, it is natural to add another command in
cat-file --batch-command to print object info for a given object
from a remote.
Add remote-object-info command to cat-file --batch-command.
While info takes object ids one at a time, this creates overhead when
making requests to a server. So remote-object-info instead can take
multiple object ids at once.
The cat-file --batch-command command is generally implemented in the
following manner:
- Receive and parse input from user
- Call respective function attached to command
- Get object info, print object info
In --buffer mode, this changes to:
- Receive and parse input from user
- Store respective function attached to command in a queue
- After flush, loop through commands in queue
- Call respective function attached to command
- Get object info, print object info
Notice how the getting and printing of object info is accomplished one
at a time. As described above, this creates a problem for making
requests to a server. Therefore, remote-object-info is implemented in
the following manner:
- Receive and parse input from user
If command is remote-object-info:
- Get object info from remote
- Loop through and print each object info
Else:
- Call respective function attached to command
- Parse input, get object info, print object info
And finally for --buffer mode remote-object-info:
- Receive and parse input from user
- Store respective function attached to command in a queue
- After flush, loop through commands in queue:
If command is remote-object-info:
- Get object info from remote
- Loop through and print each object info
Else:
- Call respective function attached to command
- Get object info, print object info
To summarize, remote-object-info gets object info from the remote and
then loops through the object info passed in, printing the info.
In order for remote-object-info to avoid remote communication
overhead in the non-buffer mode, the objects are passed in as such:
remote-object-info <remote> <oid> <oid> ... <oid>
rather than
remote-object-info <remote> <oid>
remote-object-info <remote> <oid>
...
remote-object-info <remote> <oid>
Placeholders in the format are validated against an allow-list of the
atoms the remote path supports: "objectname" and "objectsize".
Unsupported atoms expand to an empty string, honoring how for-each-ref
handles known but inapplicable atoms.
Without this, atoms like %(objecttype) would mark data->info.typep and
because the server only sends size, type_name() would later crash.
As extra safety, even outside of the remote path, initialize
expand_data's type to OBJ_BAD and handle type_name() returning NULL.

Currently, send_info() only checks for existence when the attribute
'size' is also requested. Requesting a bare OID, without attributes only
echoes back the OID.
Extract the existence check to be done regardless of the number of
attributes requested.
While at it, introduce a wrapper called get_object_info() similar to
odb_read_object_info() that returns OBJ_BAD on fail and adds
OBJECT_INFO_SKIP_FETCH_OBJECT and OBJECT_INFO_QUICK flags.
OBJECT_INFO_SKIP_FETCH_OBJECT is so a server with a partial clone
doesn't trigger fetching objects when it gets an object-info request
with an OID that is not available locally. A server should only report
what it has locally.
Tighten the condition used to determine whether an object is
recognized. get_object_info() returns OBJ_BAD for unknown objects,
but OBJ_NONE (0) can also mean "not found". Change the check from '< 0'
to '<= OBJ_NONE' to cover both as unrecognized.
With this patch, a bare OID has two possible responses:
1. Recognized OID: the server answers with "<OID>"
2. Unrecognized OID: the server answers with "<OID> SP"
Update the object-info section in 'gitprotocol-v2.adoc':
- Require full obj-oid explicitly.
- Fix parentheses.
- Define obj-size explicitly.
- Make obj-size optional in obj-info and document the behavior
for unrecognized object IDs.
- Describe the attr header as zero or more pkt-lines, one per attribute,
matching what the server implements. A request with no attributes gets
no header.

Pack requests stage downloads in a predictable partial-pack file so an
interrupted transfer can be resumed. Both packfile URI and ordinary dumb
HTTP requests use this staging path. Opening it in append mode forces
each write to the current end of the file, so concurrent responses can
append duplicate data and corrupt the pack.
Open the partial pack read-write without O_APPEND and seek once to its
current end. Each downloader then retains the offset matching the Range
it requested. Because the staging key must uniquely identify immutable
pack contents, overlapping responses write the same bytes at the same
offsets instead of extending the file with duplicate data.
MinGW's non-append O_RDWR open grants FILE_SHARE_DELETE only for an
existing file. Create a missing partial pack exclusively, close it, and
reopen it without O_CREAT so every retained descriptor permits another
downloader to unlink the staging path. Duplicate that descriptor for
index-pack instead of reopening the path after closing the stream;
index-pack installs its own pack and the shared staging file is only
unlinked, never renamed. Accept HTTP 416 when a partial pack is already
complete and let index-pack validate its contents.
Exercise resumed transfers, EOF ranges, overlapping 200 and 206
responses, and unlinking the staging path while index-pack still holds
its descriptor. Clarify the staging-key documentation.

Add a built-in userdiff driver for the Swift programming language so that
diff hunk headers and word diffs work out of the box for ".swift" files.
The funcname pattern is built for Swift's own declaration grammar: an
optional run of attributes ("@objc", "@available(iOS 13, *)", ...),
followed by an optional run of lowercase modifiers ("public", "static",
"final", ...), followed by a declaration keyword (func, class, struct,
enum, protocol, extension, actor, init, deinit, subscript). The keyword
is followed by a boundary that allows whitespace, "(" (init/subscript),
"?" or "!" (failable init), or "<" (generics), while still acting as a
word boundary so e.g. "initialize(" does not match.
The word regex recognizes Swift identifiers, hexadecimal, octal, binary,
integer and floating-point literals, and the language's operators.

Git accepts a repository URL as branch.<name>.pushRemote and can push
to it. This branch setting takes precedence over remote.pushDefault.
A branch can be configured with a URL-valued pushRemote before any push
occurs. If the remotes are later rearranged with "git remote rename" and
"git remote add", the newly added remote may use that URL. The URL value
is unaffected by the rename and continues to take precedence over
remote.pushDefault. The URL and the remote then point to the same
repository, but Git does not connect them for tracking. Pushing works,
but @{push} cannot identify the remote's tracking branch. As a result,
"git status" cannot show the push branch, and an up-to-date push can
leave its tracking information stale.
When exactly one configured remote would push to the same URL, use that
remote for push tracking. Continue to push to the URL so the configured
remote's push settings do not change existing behavior. Keep the current
behavior when no remote matches or multiple remotes match.

By default "git history squash" reuses the oldest commit's message, or
the replacement body from an amend! commit targeting it. When
--reedit-message is given it only reopened that selected message, so the
messages of the other commits in the range were lost.
Gather the message of every commit in the range and build the same editor
template that "git rebase -i --autosquash" shows for a squash, reusing
add_squash_combination_header(), add_squash_message_header() and
squash_subject_comment_len(). Feed the range through
todo_list_rearrange_squash() so that each fixup!, squash! or amend! is
grouped under the commit it targets rather than shown in commit order,
exactly as autosquash would arrange them.
Only the message text differs, the changes are always folded in. A fixup!
message is commented out in full under a "will be skipped" header, a
squash! keeps its body with only the marker subject commented, and an
amend! replaces its target's message unless a squash! already folded into
that target, in which case it behaves like a squash!.

Folding a series of commits into one required either an interactive
rebase where each commit after the first was hand-edited to "fixup", or
a "git reset --soft" to the merge base followed by "git commit --amend".
Add "git history squash <revision-range>" to do this directly. It folds
every commit in the range into the oldest one, keeping that commit's
authorship and taking the tree of the newest commit, then replays the
commits above the range on top. The squashed message comes from the
oldest commit by default, or from the body of the last amend! commit
targeting it. An editor opens with the selected message when
--reedit-message is given. A fixup!, squash! or amend! commit is refused
unless the commit it targets is also in the range, so the fold does not
silently absorb a marker meant for a commit outside it. The check runs
the range through todo_list_rearrange_squash(), which leaves such a
marker as a plain pick. Markers whose target is in the range fold in as
usual. As an exception, a range made up entirely of markers for one
target is combined anyway, taking its message from the last amend! if
there is one, so a batch of fixups for the same commit can be collapsed.
The range is read like the arguments to "git rev-list", so several
revisions such as "HEAD~3..HEAD ^topic" may be given, and rev-list
options are accepted too. As "git replay" does, the walk options the fold
relies on are forced after setup_revisions() and a warning is printed if
an option changed them, so the first commit returned is the range's
oldest and its parent is the base regardless of what the user passed
(including after a "--"). A merge inside the range is folded when its
other parent is reachable from the base, otherwise the range has more
than one base and is rejected. By default the command also refuses when a
ref points at a commit that the fold would discard. Use --update-refs=head
to rewrite only the current branch instead.

When a bisection finishes, "git bisect" reports the first bad commit
but leaves the session active until "git bisect reset" is run by hand.
Add a "--reset-when-found[=<where>]" option, accepted by both "git
bisect start" and "git bisect run", that resets as soon as the first
bad commit is found. The "original" value returns to the commit checked
out before "git bisect start", while "found" leaves the first bad commit
checked out; omitting the value defaults to "original".
Persist the selected target in a BISECT_RESET_WHEN_FOUND state file
and perform the reset quietly.
For "git bisect run", defer the reset until after the captured output
is printed and BISECT_RUN is closed. This lets cleanup remove the file
on systems that cannot unlink an open file.
Reject this option together with "--no-checkout", since that mode must
not check out either target.
