linearize the replayed history, mimicking git rebase
--no-rebase-merges.
* tc/replay-linearize:
replay: offer an option to linearize the commit topology
replay: add helper to put entry into mapped_commits
replay: refactor enum replay_mode into a bool
'git branch --contains' and 'git for-each-ref --contains' have
been optimized to use the memoized commit traversal previously
used only by 'git tag --contains', significantly speeding up
connectivity checks across many candidate refs with shared
history.
* td/ref-filter-memoize-contains:
commit-reach: die on contains walk errors
ref-filter: memoize --contains with generations
commit-reach: reject cycles in contains walk

branch: add branch.<name>.deleteMerged opt-out
branch: add --delete-merged <branch>
branch: prepare delete_branches for a bulk caller
branch: let delete_branches skip unmerged branches on bulk refusal
branch: convert delete_branches() to a flags argument
branch: add --forked filter for --list mode
The lazy priority queue optimization pattern (deferring actual removal
in prio_queue_get() to allow get+put fusion) has been folded directly
into prio_queue itself, speeding up commit traversal workflows and
simplifying callers.
* kk/prio-queue-get-put-fusion:
prio-queue: fold lazy_queue into prio_queue for automatic get+put fusion
prio-queue: rename .nr to .nr_ and add accessor helpers
The `remote-object-info` command has been added to `git cat-file
--batch-command`, allowing clients to request object metadata
(currently size) from a remote server via protocol v2 without
downloading the entire object.
The client dynamically filters format placeholders based on
server-advertised capabilities and safely returns empty strings for
inapplicable or unsupported fields.
* ps/cat-file-remote-object-info:
cat-file: make remote-object-info allow-list dynamic
cat-file: validate remote atoms with allow_list
cat-file: add remote-object-info to batch-command

to ignore configuration include directives.
Retracted.
cf. <539713c4-b291-42e6-8541-a16a454518f5@gmail.com>
* ds/config-no-includes:
git: add --no-includes top-level option
config: add GIT_CONFIG_INCLUDES
git-config.adoc: fix paragraph break
Commands that list branches and tags (like git branch and git tag)
have been optimized to pass the namespace prefix when initializing
their ref iterator, avoiding a loose-ref scaling regression in
repositories with many unrelated loose references.
* td/ref-filter-restore-prefix-iteration:
ref-filter: restore prefix-scoped iteration
The packed object source has been refactored into a proper struct
odb_source.

odb/source-packed: wire up `for_each_object()` callback
odb/source-packed: wire up `read_object_stream()` callback
odb/source-packed: wire up `read_object_info()` callback
packfile: use higher-level interface to implement `has_object_pack()`
odb/source-packed: wire up `reprepare()` callback

packfile: split out packfile list logic
packfile: rename `struct packfile_store` to `odb_source_packed`
When cURL follows a redirect, the WWW-Authenticate headers from the
redirect target were lost because credential_from_url() cleared the
credential state. This has been fixed by preserving the collected
headers across the redirect update.
* ap/http-redirect-wwwauth-fix:
http: preserve wwwauth_headers across redirects
A regression in the error diagnosis code for invalid .git files has
been fixed, avoiding a potential NULL-pointer crash when reporting
that a .git file does not point to a valid repository.
* jk/setup-gitfile-diag-fix:
read_gitfile_gently(): return non-repo path on error
The experimental "git history" command has been taught a new "drop"
subcommand to remove a commit and replay its descendants onto its
parent.
* ps/history-drop:
builtin/history: implement "drop" subcommand
builtin/history: split handling of ref updates into two phases

repo: add path.gitdir with absolute and relative suffix formatting
repo: add path.commondir with absolute and relative suffix formatting
rev-parse: use append_formatted_path() for path formatting
path: introduce append_formatted_path() for shared path formatting
prio_queue_get() has been optimized by using a cascade-down approach
(promoting the smaller child at each level and sifting up the last
element from the leaf vacancy), which halves the number of comparisons
per extract-min operation in the common case.
* kk/prio-queue-cascade-sift:
prio-queue: use cascade-down for faster extract-min
The 'trust_executable_bit' (coming from 'core.filemode'
configuration) has been migrated into 'repo_config_values' to tie it
to a specific repository instance.
* ty/migrate-trust-executable-bit:
environment: move trust_executable_bit into repo_config_values
read-cache: move 'ce_mode_from_stat()' to 'read-cache.c'
read-cache: remove redundant extern declarations
The pack-objects command now supports using reachability bitmaps and
delta-islands concurrently with the `--path-walk` option, allowing
faster packaging by falling back to path-walk when bitmaps cannot
fully satisfy the request.
* tb/pack-path-walk-bitmap-delta-islands:
pack-objects: support `--delta-islands` with `--path-walk`
pack-objects: extract `record_tree_depth()` helper
pack-objects: support reachability bitmaps with `--path-walk`
t/perf: drop p5311's lookup-table permutation
"git rebase --update-refs" has been taught to resolve local branch
symrefs to their referents before queuing updates. This correctly
skips aliases of the current branch and avoids duplicate updates for
underlying real branches, fixing failures when branch aliases (like a
default branch rename) are present.
* sn/rebase-update-refs-symrefs:
rebase: skip branch symref aliases
The -m/-F/-c/-C options to supply commit log message from outside the
editor are now supported for all "git commit --fixup" variations.
* ec/commit-fixup-options:
commit: allow -c/-C for all kinds of --fixup
commit: allow -m/-F for all kinds of --fixup
The [includeIf "condition"] conditional inclusion facility for
configuration files has learned to use the location of worktree
in its condition.

pass the transport pointer to the post-fetch `check_connected()` call
to optimize connectivity check.
Retracted.
cf. <CAL71e4MrVqC1=AR6x0_8S=8kVqPdDkhgCZRb4etFsxTzd6s_8Q@mail.gmail.com>
* kk/fetch-store-ref-optimization:

failures when multiple processes attempt to update the configuration
simultaneously.
* jt/config-lock-timeout:
config: retry acquiring config.lock, configurable via core.configLockTimeout
The parse-options library learned to auto-correct misspelled
subcommand names.

help: move tty check for autocorrection to autocorrect.c
help: make autocorrect handling reusable
parseopt: extract subcommand handling from parse_options_step()
The display of the rebase todo list in "git status" has been
improved to correctly abbreviate object IDs for more commands and
avoid misinterpreting refs as object IDs.
* pw/status-rebase-todo:
status: improve rebase todo list parsing
sequencer: factor out parsing of todo commands
When fetching objects into a lazily cloned repository, .promisor
files are created with information meant to help debugging. "git
repack" has been taught to carry this information forward to
packfiles that are newly created.
Retracted.
cf. <agx_GPfBKpkSc3Gx@lorenzo-VM>

Project-specific configuration for b4 has been introduced, and the
documentation has been updated to recommend using it as a
streamlined method for submitting patches.
* ps/doc-recommend-b4:
b4: introduce configuration for the Git project
MyFirstContribution: recommend the use of b4
MyFirstContribution: recommend shallow threading of cover letters
compute_reachable_generation_numbers() in commit-graph used a 32-bit
integer to accumulate parent generations, which is OK for generation
number v1 (topological levels), but with generation number v2
(adjusted committer timestamps), it truncated timestamps beyond
2106. Fixed by widening the accumulator to timestamp_t.
* en/commit-graph-timestamp-fix:
commit-graph: use timestamp_t for max parent generation accumulator
"ort" merge backend handles merging corrupt trees better by
aborting when it should.

newly introduced GIT_CLANG_PREREQ macro for compiler version
checks, and the existing GIT_GNUC_PREREQ macro has been modernized
to use explicit major/minor comparisons rather than bit-shifting.
* dl/posix-unused-warning-clang:
compat/posix.h: simplify GIT_GNUC_PREREQ() comparison
compat/posix.h: clean up GIT_GNUC_PREREQ() and UNUSED
compat/posix.h: enable UNUSED warning messages for Clang
`git ls-files --modified` and `git ls-files --deleted` have been
optimized to filter with pathspec before calling lstat() when there is
only a single pathspec item, avoiding unnecessary filesystem access
for entries that will not be shown.
* td/ls-files-pathspec-prefilter:
ls-files: filter pathspec before lstat

describe: limit default ref iteration to tags
The global configuration variables protect_hfs and protect_ntfs have
been migrated into struct repo_config_values to tie them to
per-repository configuration state.
* ty/move-protect-hfs-ntfs:
environment: move 'protect_hfs' and 'protect_ntfs' into 'repo_config_values'
The TSAN race in transfer_debug() within transport-helper.c has been
resolved by initializing the debug flag early in
bidirectional_transfer_loop() before spawning worker threads, allowing
the removal of a TSAN suppression.
* ps/transport-helper-tsan-fix:
transport-helper: fix TSAN race in transfer_debug()
The handling of promisor-remote protocol capability has been
loosened to allow the other side to add to the list of promisor

Advice shown by "git status" when the local branch is behind or has
diverged from its push branch has been updated to suggest "git pull
<remote> <branch>".
* hn/status-pull-advice-qualified:
remote: qualify "git pull" advice for non-upstream compareBranches
"git index-pack" has been optimized by retaining child bases in the
delta cache instead of immediately freeing them, letting the existing
cache limit policy decide eviction.
* ab/index-pack-retain-child-bases:
index-pack: retain child bases in delta cache
The subprocess handshake during startup has been made gentler by using
packet_read_line_gently() instead of packet_read_line() to prevent the
parent Git process from dying abruptly when a configured subprocess
(e.g., a clean/smudge filter) fails to start.
* mm/subprocess-handshake-fix:
sub-process: use gentle handshake to avoid die() on startup failure
Various typos, grammatical errors, and duplicated words in both
