The terminology regarding reference storage formats has been unified
across command-line options, environment variables, configuration
variables, and source code, standardizing on the phrase "ref storage
format" (e.g., `--ref-storage-format`, `'GIT_REF_STORAGE_FORMAT'`).
Additionally, the `--ref-storage-format` option has been updated to
accept payloads in the form `<format>://<payload>`.
* ps/ref-storage-format:
setup: allow "--ref-storage-format=" to specify a payload
setup: rename "init.defaultRefFormat" to "init.defaultRefStorageFormat"
t: rename GIT_TEST_DEFAULT_REF_FORMAT
setup: rename ref storage format environment variables
setup: refactor how we configure the ref storage format
refs: expose function to parse reference URIs
help: rename "default-ref-format" to "default-ref-storage-format"
builtin/rev-parse: rename "--show-ref-format" to "--show-ref-storage-format"
builtin/submodule: rename "--ref-format=" to "--ref-storage-format="
builtin/refs: rename "--ref-format=" to "--ref-storage-format="
builtin/clone: rename "--ref-format=" to "--ref-storage-format="
builtin/init: rename "--ref-format=" to "--ref-storage-format="
parse-options: allow for hidden aliases

When cross-compiling with Cargo, the output artifact is placed in a
target-specific subdirectory, which causes the build system to fail
to locate it. The build system has been updated to respect the
'CARGO_BUILD_TARGET' environment variable.
* jc/rust-cargo-build-target:
rust: respect CARGO_BUILD_TARGET when locating build output
|
|
Some advice messages would never trigger once a repository is
initialized (e.g., advice.defaultBranchName). Update hint to
disable them in per-user configuration file.
* vm/advice-config-global-hint:
fixup! advice: introduce advice scoping mechanism
advice: use global config for default branch name
advice: introduce advice scoping mechanism
advice: pass the entire advice_setting to vadvise()

The --force-if-includes protection for git push has been updated to
consult the reflog of the local branch being pushed, rather than
incorrectly checking the reflog of a local branch that shares the
name of the remote destination branch. The push advice for detached
HEAD scenarios has also been adjusted to indicate that the remote
ref cannot be verified locally.
* tc/push-force-if-includes-fixes:
push: fix --force-if-includes detached HEAD advice
push: check pushed ref for --force-if-includes
|
|
The sequencer machinery (used by 'git rebase', 'git cherry-pick', and
'git revert') has been updated to defer automatic maintenance tasks
until the end of the operation, preventing nested 'git commit', 'git
merge', and 'exec' commands from triggering GC operations that could
contend for locks or delete open packs while the sequence is in
progress.
* tb/rerere-lock-grace:
sequencer: disable auto maintenance in spawned commands
rebase, cherry-pick, revert: run auto maintenance when done
config: add git_config_append_parameter()
|
|
The timestamp used for checking the reflog of a remote-tracking
branch during 'git push --force-if-includes' was left uninitialized
when the reflog was completely empty, which has been corrected.
* as/push-force-if-includes-no-reflog:
push: fix --force-if-includes when remote-tracking ref has no reflog
|
|
A new 'diff.<driver>.process' configuration has been introduced to
allow a long-running external process to act as a hunk provider,
enabling external tools to control which lines Git considers changed
while leaving all output formatting (word diff, color, blame, etc.) to
Git's standard pipeline.
* mm/diff-process-hunks:
fixup! diff: consult oid-only hunk providers via diff.<driver>.process
diff: consult oid-only hunk providers via diff.<driver>.process
userdiff: add diff.<driver>.process config
sub-process: add a gentle status read
sub-process: separate process lifecycle from hashmap management
blame: read precomputed hunks
diff: read precomputed hunks for stat output
diff: record precomputed hunks during stat output
diff-hunks: add the store format, library, and command
diff: introduce a hunk provider interface
gitattributes: document how external diff drivers relate to diff features
|

The process of parsing command-line options in commands that
perform an early scan over their arguments (such as 'git bisect',
'git rev-parse', and 'git fast-import') has been unified using a
new early-scan sub-API, which parses and skips known options taking
separate values to prevent logic bugs.
* cc/early-scan-options:
fast-import: use early_scan_options() for --allow-unsafe-features
parse-options: build early scan options from a struct option array
parse-options: add parse_options_takes_argument()
rev-parse: fix "--" detection when it is an option value
bisect: fix "--" detection when a term name is "--"
parse-options: add early_scan_options()
|

The 'git last-modified' command has been optimized by using Bloom
filters. It now reuses revision walk filtering logic from 'git log'
to pre-filter commits, and maintains per-path Bloom filters even when
wildcard pathspecs are used.
* tc/last-modified-bloom:
last-modified: keep per-path Bloom filters for wildcard pathspecs
last-modified: check pathspec against Bloom filter first
revision: add Bloom check that includes parent directories
bloom: add helper to check if any key in a vector is present
revision: expose check for paths maybe changed in Bloom filter
revision: move bloom keyvec precondition into function
|
|
he remote helper documentation for the 'pushcert' option has been
updated to mention that it can also take 'if-asked', reflecting the
existing implementation in the code.
* ll/doc-pushcert-if-asked:
doc: remote-helpers: option pushcert if-asked
|
|
The front-end code for 'git checkout', 'git switch', and 'git
restore' has been restructured to cleanly separate their pathspec
and branch handling, eliminating a common bottleneck and paving the
way to libify utility helpers.
* jc/checkout-refactor:
checkout: move post_checkout_hook() to checkout.c
checkout: wrap overly long lines
checkout: restructure switch, restore, and checkout entrypoints
checkout: extract branch setup and tracking helpers
checkout: extract option validation and pathspec helpers
checkout: validate stage and merge option compatibility in checkout_paths()
checkout: validate new branch name in checkout_branch()
checkout: pass cb_option explicitly to branch name parsers
|
|
A commit that is emptied by melding a 'fixup!' or 'squash!' commit
during 'git rebase --autosquash' is now handled according to the
'--empty' option, allowing it to be dropped, kept, or to halt the
rebase.
* fz/rebase-autosquash-empty:
sequencer: honor --empty when a fixup!/squash! empties its target
|
|
* ws/squelch-svn-migrate:
Makefile: add NO_GIT_SVN knob to skip building/installing git-svn
git-svn: don't print v1-layout migration noise when there's nothing to migrate
|
|
The experimental 'git history' command has been taught a new 'squash'
subcommand to fold a range of commits into a single commit, with any
descendants replayed on top.
* hn/history-squash:
history: support editing squashed commit messages
history: create squashed commits without editing
history: protect branches when squashing a range
history: validate squash revision ranges
history: add skeleton for squash subcommand
sequencer: share the squash message marker helpers and flags
history: give commit_tree_ext a message template
history: extract helper for a commit's parent tree
|
|
The experimental 'git format-rev' has been taught a few more
formatting options.

format-rev: learn --abbrev, --color, and --date
doc: rev-list-options.adoc: factor out --date alts
format-rev: factor option variables into a struct
format-rev: place BUG calls first in callback
format-rev: use lower case for opts description
|
|
The HTTP transport has been taught to check the revocation status of
the server certificate using the stapled OCSP response during the
TLS handshake via a new 'http.sslVerifyStatus' configuration
variable.
* gg/http-ssl-verify-status:
http: add http.sslVerifyStatus to check stapled OCSP responses
|
|
A new 'uploadpack.lazyFetchTrusted' configuration variable has been
introduced to allow 'upload-pack' to lazily fetch missing objects from
configured promisor remotes when serving trusted repositories.
* cc/lazy-fetch-trusted-bit:
builtin/upload-pack: set GIT_NO_LAZY_FETCH to 0 on trusted repo
promisor-remote: prevent infinite recursion when lazy fetching
upload-pack: read uploadpack.lazyFetchTrusted
setup: extract path_allowlist_apply()
promisor-remote: factor out lazy_fetch_objects()
|
|
Repository configuration getters in 'environment.c' have been
simplified by removing redundant NULL checks. The documentation for
these getters in 'environment.h' has been clarified, and inaccurate
section comments inside 'struct repo_config_values' have been removed.
* ty/repo-config-cleanups:
environment: remove inaccurate repo_config_values comments
environment: clarify repository config getter documentation
environment: drop redundant NULL checks in config getters

The parser for hex object names has been updated to reject uppercase
hexadecimal characters when running in the breaking changes mode, in
preparation for Git 3.0.
* bc/restrict-hex-to-lowercase:
hex: allow only lowercase object IDs in breaking changes mode
t5324: adjust tests for corrupt commit-graph
object-name: use hexval
hex: label usages of hex parsing for object IDs
hex: make hex_to_bytes accept kind of hex to use
hex: allow specifying hex type with hex2chr
hex: add functionality for lowercase-only hex
|
|
The handling of packfiles with duplicate object entries has been
hardened. Specifically, reverse index lookup, delta cycle
recovery, multi-pack-index verification, and pack reuse paths have
been updated to correctly handle or gracefully reject duplicate
entries.
* tb/pack-with-duplicates:
pack-bitmap: handle duplicate pack entries during MIDX reuse
test-tool bitmap: reject packs with duplicate objects
midx: verify duplicate pack entries by OID and offset
packfile: recover delta cycles through duplicate entries
t5308: test reverse indexes with duplicate objects
|
|
The 'git fetch' command can now configure how submodule fetch errors
are handled via 'fetch.submoduleErrors' and '--submodule-errors',
making them non-fatal. A premature failure during recursive submodule
fetches has been fixed by deferring the error until the OID-based
retry phase fails.
* pz/fetch-submodule-errors-config:
fetch: add fetch.submoduleErrors to make submodule fetch errors non-fatal
submodule: fix premature failure in recursive submodule fetch
|
|
Support for skipping the editor when continuing a rebase after
conflict resolution has been added with the '--no-edit' option, and
forcing it with '--edit'. A new configuration variable
'rebase.noEdit' can be used to set the default behavior.
* hs/rebase-continue-edit:
rebase: add --[no-]edit to --continue
|
|
The 'git repo info' command has been taught more keys to output
paths of various repository components (such as the working tree
root, superproject working tree, object database, etc.), supporting
both absolute and relative path formats.
* kj/repo-info-more-path-keys:
repo: add path.cdup
repo: add path.git-prefix
repo: add path.grafts with absolute and relative suffixes
repo: add path.index with absolute and relative suffixes
repo: add path.hooks with absolute and relative suffixes
repo: add path.superproject-root with absolute and relative suffixes
repo: add path.toplevel with absolute and relative suffix formatting

|
Functions like `xstrfmt()` and `xcalloc()` have been banned from use
in the trace2 API codebase to prevent calls to `die()` which lead to
unwanted process exits and recursion when memory allocation fails.
* ds/trace2-tolerate-failed-timestamp:
trace2: remove use of xcalloc()
trace2: remove use of ALLOC_GROW()
trace2: remove use of xstrfmt()
trace2: remove use of ALLOC_ARRAY()
trace2: remove use of xstrdup()
trace2: tolerate failed timestamp formatting
banned-die: create header for banning of functions

various 'diff' operations, such as '--stat', '--check', and '-G', to
the specified range and path.
* mm/line-log-limited-ops:
diffcore-pickaxe: limit -G to the -L tracked range
diff: support --check with -L line ranges
diff: support stat formats with -L
diff: extract a line-range diff helper for reuse
diff: emit -L hunk headers via xdiff's formatter
diff: simplify the line-range filter by classifying removals immediately
diff: rename line-range filter struct and clarify fields
|

The 'git multi-pack-index write --incremental' command has been
corrected to properly honor the '--base' option. Previously, the
custom base was ignored by the normal write path; packs from layers
above the selected base were incorrectly skipped by the pack exclusion
logic, and reachability closure for bitmaps was broken.
* tb/midx-incremental-custom-base:
midx-write: include packs above custom incremental base
midx: pass custom '--base' through incremental writes
t5334: expose shared `nth_line()` helper
|
|
'git rebase --update-refs' has been taught to resolve local branch
symrefs to their referents before queuing updates, ensuring aliases of
the current branch are skipped and duplicate updates are avoided to
prevent failures when branch aliases are present.
* sn/rebase-update-refs-symrefs:
rebase: guard non-branch symref targets
rebase: skip branch symref aliases
|
|
Support for '-m', '-F', '-c', or '-C' options to supply a commit log
message from outside the editor has been added 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
|
|
Mark-up fix for 'git maintenance' documentation pages.
* bc/maintenance-doc-markup-fix-for-asciidoc:
doc: fix conjoined maintenance strategies in git-config(1)
|
|
A new linter test has been added to Documentation/lint-manpages.sh
to ensure that all non-command manual pages (guides and developer
interfaces) listed in Documentation/Makefile are present in
command-list.txt, replacing an older comment that reminded
developers to keep them in sync.
* ta/command-list-guides-sync-lint:
lint-docs: check the guide list in command-list.txt
command-list: add gitformat-loose(5) and gitpacking(7)
|
|
The consistency checks for the object database (fsck) have been
decoupled from the generic builtin implementation and moved into the
backend-specific object source layers, making them pluggable for
different object storage formats.
* ps/odb-pluggable-fsck:
builtin/fsck: move loose object verification into the loose source
builtin/fsck: move multi-pack index verification into the packed source
builtin/fsck: move bitmap verification into the packed source
builtin/fsck: move reverse index verification into the packed source
builtin/fsck: move packfile verification into the packed source
odb: provide infrastructure for pluggable fsck checks
builtin/fsck: don't check alternates with "--no-full"
builtin/fsck: de-globalize option handling
builtin/fsck: merge `fsck_obj_buffer()` and `fsck_obj()`
builtin/fsck: use `fsck_obj_buffer()` when checking loose objects
|
|
The setup of alternates has been deferred to object database
creation time during clone, which drops the unused ad-hoc alternate
writing API, simplifying the object database backend interface.
* ps/odb-alternates-at-creation:
odb/source: remove the ability to write alternates
builtin/clone: write alternates via `odb_create_on_disk()`
odb/source: support writing alternates when creating the database
builtin/clone: move setup of alternates for non-shared local clones
builtin/clone: move setup of alternates for shared local clones
builtin/clone: refactor handling of "--reference{,-if-able}"
builtin/clone: move around `setup_reference()`
builtin/clone: defer setup of the object database
setup: split up concerns of `init_db()`
|
|
The git config --global read operations have been updated to respect
both $HOME/.gitconfig and $XDG_CONFIG_HOME/git/config, fixing an
inconsistency where only the former was read when both configuration
files are present.
* dw/config-read-both-global:
config: read global scope via config_sequence
config: let sequence require a successful file
path: use forward slashes in XDG config on Windows
|
|
The --recurse-submodules option in 'git branch' has been fixed to
avoid a crash when the start point is not a reference (e.g., a raw
object ID). The creation path now skips setting up tracking and
properly forwards the absent tracking name to the submodule helper.
* vv/branch-recurse-no-start-ref:
branch: allow recursion with no tracking name
branch: do not track a start point with no ref
|
|
The codebase has been updated to use the newer utimensat() POSIX
function instead of the obsolescent utime(), allowing
high-precision timestamps while preserving fallback compatibility.
* as/utimensat-utimes:
compat/posix: drop legacy <utime.h> header and shims
treewide: use utimensat(2) instead of legacy utime(3p)
compat/posix: introduce utimensat(2) wrapper
|
|
When an HTTP request triggers a redirect and the target yields an
authentication challenge, the WWW-Authenticate headers received
during the redirect are now explicitly preserved across the
credential URL update, fixing an issue where they were incorrectly
cleared.
* ap/http-preserve-wwwauth-redirect:
http: preserve wwwauth_headers across redirects
|
|
A compatibility workaround has been introduced for macOS to address
a memory leak in the system regex engine when it encounters invalid
multibyte sequences. The workaround segments the input buffer at
invalid byte boundaries and searches each valid segment separately
using regexec(), avoiding the leaking path.
* cl/regexec-macos-leak:
SQUASH???
regexec: work around macOS TRE leak on invalid UTF-8
|
|
The shell script implementation of 'git subtree' has been updated to
check for the presence of the configuration file of the new Rust
implementation, preventing users from accidentally running the old
script on repositories already managed by the new tool.
* ij/subtree-reject-v2-config:
git-subtree: Bail out if we find output from Rust rewrite (test)
git-subtree: Bail out if we find output from Rust rewrite
|
|
The build-time knob 'USE_NSEC' for nanosecond stat precision has been
converted to a runtime configuration 'core.useNanosec', allowing
distributions to bundle one binary that adapts to filesystem
capabilities dynamically.
* dk/use-nsec-runtime:
core: convert build-time USE_NSEC into runtime core.useNanosec
environment: align repo_config_values_init with struct declaration
meson: expose knob for xmlto relative links in manuals
|
|
The pathspec matching logic has been updated to avoid out-of-bounds
memory accesses when a negative pathspec is shorter than the common
prefix of positive pathspecs.
* yt/pathspec-negative-prefix:
dir: find common prefix among non-exclude pathspec items
dir: do not apply prefix to negative pathspecs
|
|
A new hook 'report' is added to 'git receive-pack', which runs after
reference updates and allows the server to filter or modify the
packet-line status report sent back to the client.
* kn/receive-report-hook:
hook: introduce the receive-report hook
receive-pack: move message generation to separate function
receive-pack: drop static variables to track report status version
doc: add proc-receive hook info in 'git-receive-pack.adoc'
|
|
The mechanism to register in-memory alternate object sources has
been removed, as submodule object databases are now accessed
natively via their own repository structures. This simplifies
object database management and prepares the codebase for migrating
alternate tracking into the files backend.
* ps/odb-stop-registering-in-memory-sources:
odb: remove the ability to link sources ad-hoc
t/helper: stop registering alternates in "ref-store" command
t/helper: adapt read-midx to not link ad-hoc source anymore
builtin/multi-pack-index: refuse unknown sources with "--object-dir="
odb/packed: fix memory leaks when freeing source
tmp-objdir: drop unused function to register alternate
odb: remove infrastructure to register submodule sources
builtin/grep: stop registering submodule ODB as source
submodule-config: stop registering submodule sources
submodule-config: stop using `the_hash_algo`
submodule-config: remove uses of `the_repository`
cache-tree: remove dependency on `the_repository`
cache-tree: drop `the_repository` in `cache_tree_fully_valid()`

A collection of patches from Git for Windows has been upstreamed,
mostly focusing on simplifying and robustifying build configurations
for MinGW/MSYS2, dropping obsolete compatibility options, and allowing
the main 'git.exe' to be used directly without the extra wrapper
process on Windows.
* js/mingw-build-updates:
t0060: adjust the code style
mingw: allow `git.exe` to be used instead of the "Git wrapper"
mingw: ensure valid CTYPE
mingw: always define `ETC_*` for MSYS2 environments
windows: skip linking `git-<command>` for built-ins
mingw: rely on MSYS2's metadata instead of hard-coding it
mingw: only enable the MSYS2-specific stuff when compiling in MSYS2
mingw: set the prefix and HOST_CPU as per MSYS2's settings
mingw: avoid over-specifying `--pic-executable`
mingw: only use -Wl,--large-address-aware for 32-bit builds
mingw: drop the -D_USE_32BIT_TIME_T option
mingw: stop hard-coding `CC = gcc`
mingw: include the Python parts in the build

The development helper script to lint gitlink references in the
documentation has been updated to avoid a newer Perl regular
expression syntax that breaks on older Perl versions.
* ta/lint-gitlink-older-perl-fix:
lint-gitlink: don't use empty lower bound in .{0,8}
|
|
Running "git history" in a corrupt repository can (unsurprisingly)
segfault when a necessary tree object is not found.
* jc/history-missing-tree-errorfix:
history: do not dereference NULL when parent tree is missing
|
|
The documentation for 'git cherry-pick' has been updated to clarify
that the '--no-commit' option intentionally skips setting the
'CHERRY_PICK_HEAD' ref. A test has also been added to ensure this
behavior holds even when the operation stops for conflicts.
* as/cherry-pick-no-commit-doc:
doc: cherry-pick: note --no-commit skips CHERRY_PICK_HEAD
t3507: check no CHERRY_PICK_HEAD after conflicting --no-commit
