Git v2.55 Release Notes (draft)
===============================

UI, Workflows & Features
------------------------

 * Hook scripts defined via the configuration system can now be
   configured to run in parallel.

 * The userdiff driver for the Scheme language has been extended to
   cover other Lisp dialects.

 * Terminal control sequences coming over the sideband while talking
   to a remote repository are mostly disabled by default, except for
   ANSI color escape sequences.

 * "ort" merge backend improvements.

 * "git checkout -m another-branch" was invented to deal with local
   changes to paths that are different between the current and the new
   branch, but it gave only one chance to resolve conflicts.  The command
   was taught to create a stash to save the local changes.

 * A new builtin "git format-rev" is introduced for pretty formatting
   one revision expression per line or commit object names found in
   running text.

 * "git history" learned "fixup" command.

 * The internal URL parsing logic has been made accessible via a new
   subcommand "git url-parse".

 * Misspelt proxy URL (e.g., httt://...) did not trigger any warning
   or failure, which has been corrected.

 * Document the fact that .git/info/exclude is shared across worktrees
   linked to the same repository.

 * The command line parser for "git diff" learned a few options take
   only non-negative integers.

 * The graph output from commands like "git log --graph" can now be
   limited to a specified number of lanes, preventing overly wide output
   in repositories with many branches.

 * The fsmonitor daemon has been implemented for Linux.

 * "git cat-file --batch" learns an in-line command "mailmap"
   that lets the user toggle use of mailmap.

 * The "git pack-objects --path-walk" traversal has been integrated
   with several object filters, including blobless and sparse filters.

 * "git push" learned to take a "remote group" name to push to, which
   causes pushes to multiple places, just like "git fetch" would do.

 * The 'git-jump' command (in contrib/) has been taught to automatically
   pick a mode (merge, diff, or ws) when invoked without arguments.

 * The documentation for `push.default = simple` has been clarified to
   better explain its behavior, making it clear that it pushes the
   current branch to a same-named branch on the remote, and detailing
   the upstream requirements for centralized workflows.

 * The documentation for "--word-diff" has been extended with a bit of
   implementation detail of where these different words come from.


Performance, Internal Implementation, Development Support etc.
--------------------------------------------------------------

 * Promisor remote handling has been refactored and fixed in
   preparation for auto-configuration of advertised remotes.

 * Rust support is enabled by default (but still allows opting out) in
   some future version of Git.

 * Preparation of the xdiff/ codebase to work with Rust.

 * Use a larger buffer size in the code paths to ingest pack stream.

 * Refactor service routines in the ref subsystem backends.

 * Shrink wasted memory in Myers diff that does not account for common
   prefix and suffix removal.

 * Enable expensive tests to catch topics that may cause breakages on
   integration branches closer to their origin in the contributor PR
   builds.

 * "git merge-base" optimization.

 * The limit_list() function that is one of the core part of the
   revision traversal infrastructure has been optimized by replacing
   its use of linear list with priority queue.

 * In a lazy clone, "git cherry" and "git grep" often fetch necessary
   blob objects one by one from promisor remotes.  It has been corrected
   to collect necessary object names and fetch them in bulk to gain
   reasonable performance.

 * The logic to determine that branches in an octopus merge are
   independent has been optimized.

 * The consistency checks for the files reference backend have been updated
   to skip lock files earlier, avoiding unnecessary parsing of
   intermediate files.

 * The negotiation tip options in "git fetch" have been reworked to
   allow requiring certain refs to be sent as "have" lines, and to
   restrict negotiation to a specific set of refs.

 * The repacking code has been refactored and compaction of MIDX layers
   have been implemented, and incremental strategy that does not require
   all-into-one repacking has been introduced.

 * ODB transaction interface is being reworked to explicitly handle
   object writes.

 * Add a new odb "in-memory" source that is meant to only hold
   tentative objects (like the virtual blob object that represents the
   working tree file used by "git blame").

 * Many uses of the_repository has been updated to use a more
   appropriate struct repository instance in setup.c codepath.

 * Revision traversal optimization.

 * Build update.

 * The logic to lazy-load trees from the commit-graph has been made
   more robust by falling back to reading the commit object when
   the commit-graph is no longer available.

 * The "name" argument in git_connect() and related functions has been
   converted to a "service" enum to improve type safety and clarify its
   purpose.

 * 'git restore --staged' has been optimized to avoid unnecessarily expanding
   the sparse index when operating on paths within the sparse checkout
   definition, by handling sparse directory entries at the tree level.

 * "git stash -p" has been optimized by reusing cached index
   entries in its temporary index, avoiding unnecessary lstat()
   calls on unchanged files.

 * The check for non-stale commits in the priority queue used by
   `paint_down_to_common` and `ahead_behind` has been optimized by
   replacing an O(N) scan with an O(1) counter, yielding performance
   improvements in repositories with wide histories.

 * Reachability bitmap generation has been significantly optimized. By
   reordering tree traversal, caching object positions, and refining how
   pseudo-merge bitmaps are constructed, the performance of "git repack
   --write-midx-bitmaps" is improved, especially for large repositories
   and when using pseudo-merges.

 * Adding a decimal integer with strbuf_addf("%u") appears commonly;
   they have been optimized by using a custom formatter.

 * Formatting object name in full hexadecimal form has been optimized
   by using a new strbuf_add_oid_hex() helper function.

 * Encourage original authors to monitor the CI status.

 * The `git log -L` implementation has been refactored to use the
   standard diff output pipeline, enabling pickaxe and diff-filter to
   work as expected. Additionally, metadata-only diff formats like
   --raw and --name-only are now supported with -L.

 * The loose object source has been refactored into a proper `struct
   odb_source`.


Fixes since v2.54
-----------------

 * Code clean-up to use the right instance of a repository instance in
   calls inside refs subsystem.
   (merge 57c590feb9 sp/refs-reduce-the-repository later to maint).

 * The check that implements the logic to see if an in-core cache-tree
   is fully ready to write out a tree object was broken, which has
   been corrected.
   (merge 521731213c dl/cache-tree-fully-valid-fix later to maint).

 * The test suite harness and many individual test scripts have been
   updated to work correctly when 'set -e' is in effect, which helps
   detect misspelled test commands.
   (merge ffe8005b9d ps/test-set-e-clean later to maint).

 * Revert a recent change that introduced a regression to help mksh users.

 * Update various GitHub Actions versions.

 * Avoid hitting the pathname limit for socks proxy socket during the
   test..

 * To help Windows 10 installations, avoid removing files whose
   contents are still mmap()'ed.

 * The 'git backfill' command now rejects revision-limiting options that
   are incompatible with its operation, uses standard documentation for
   revision ranges, and includes blobs from boundary commits by default
   to improve performance of subsequent operations.
   (merge a1ad4a0fca en/backfill-fixes-and-edges later to maint).

 * "git grep" update.
   (merge 9ff4b5ab1b rs/grep-column-only-match-fix later to maint).

 * Headers from glibc 2.43 when used with clang does not allow
   disabling C11 language features, causing build failures..

 * The 'http.emptyAuth=auto' configuration now correctly attempts
   Negotiate authentication before falling back to manual credentials.
   This allows seamless Kerberos ticket-based authentication without
   requiring users to explicitly set 'http.emptyAuth=true'.
   (merge 4919938d28 mc/http-emptyauth-negotiate-fix later to maint).

 * Ramifications of turning off commit-graph has been documented a bit
   more clearly.
   (merge 48c855bb8f kh/doc-commit-graph later to maint).

 * "git rebase --update-refs", when used with an rebase.instructionFormat
   with "%d" (describe) in it, tried to update local branch HEAD by
   mistake, which has been corrected.
   (merge 106b6885c7 ag/rebase-update-refs-limit-to-branches later to maint).

 * Tweak the way how sideband messages from remote are printed while
   we talk with a remote repository to avoid tickling terminal
   emulator glitches.
   (merge 31e8fcabd8 rs/sideband-clear-line-before-print later to maint).

 * The configuration variable submodule.fetchJobs was not read correctly,
   which has been corrected.
   (merge aa45a5902f sj/submodule-update-clone-config-fix later to maint).

 * Update code paths that assumed "unsigned long" was long enough for
   "size_t".
   (merge 7a094d68a2 js/objects-larger-than-4gb-on-windows later to maint).

 * Stop using unmaintained custom allocator in Windows build which was
   the last user of the code.

 * The computation to shorten the filenames shown in diffstat measured
   width of individual UTF-8 characters to add up, but forgot to take
   into account error cases (e.g., an invalid UTF-8 sequence, or a
   control character).
   (merge 09d86a3b98 en/diffstat-utf8-truncation-fix later to maint).

 * Some tests assume that bare repository accesses are by default
   allowed; rewrite some of them to avoid the assumption, rewrite
   others to explicitly set safe.bareRepository to allow them.
   (merge 985b38ca6c js/adjust-tests-to-explicitly-access-bare-repo later to maint).

 * Signing commit with custom encoding was passing the data to be
   signed at a wrong stage in the pipeline, which has been corrected.
   (merge 7735d7eee3 bc/sign-commit-with-custom-encoding later to maint).

 * Further update to the i18n alias support to avoid regressions.

 * "git fetch --deepen=<n>" in a full clone truncated the history to <n>
   commits deep, which has been corrected to be a no-op instead.
   (merge 2431f5e0e5 sp/shallow-deepen-on-non-shallow-repo-fix later to maint).

 * "git maintenance" that goes background did not use the lockfile to
   prevent multiple maintenance processes from running at the same
   time, which has been corrected.
   (merge 29364f1624 ps/maintenance-daemonize-lockfix later to maint).

 * Remove ineffective strbuf presizing that would have computed an
   allocation that would not have fit in the available memory anyway,
   or too small due to integer wraparound to cause immediate automatic
   growing.
   (merge a9ce8526dc jk/pretty-no-strbuf-presizing later to maint).

 * The HTTP walker misinterpreted the alternates file that gives an
   absolute path when the server URL does not have the final slash
   (i.e., "https://example.com" not "https://example.com/").
   (merge b92387cd55 jk/dumb-http-alternate-fix later to maint).

 * "git bisect" now uses the selected terms (e.g., old/new) more
   consistently in its output.
   (merge cb55991825 jr/bisect-custom-terms-in-output later to maint).

 * Update GitLab CI jobs that exercise macOS.
   (merge 62319b49bb ps/gitlab-ci-macOS-improvements later to maint).

 * "Friday noon" asked in the morning on Sunday was parsed to be one
   day before the specified time, which has been corrected.
   (merge b809304101 ta/approxidate-noon-fix later to maint).

 * The GIT_WORK_TREE variable prepared to invoke the push-to-checkout
   hook was leaking into the environment even when there was no hook
   used and broke the default push-to-deploy (i.e., let "git checkout"
   update the working tree only when the working tree is clean).
   (merge 44d04e4426 ar/receive-pack-worktree-env later to maint).

 * A batch of documentation pages has been updated to use the modern
   synopsis style.
   (merge 2ef248ae45 ja/doc-synopsis-style-again later to maint).

 * The "promisor.quiet" configuration variable was not used from
   relevant submodules when commands like "grep --recurse-submodules"
   triggered a lazy fetch, which has been corrected.
   (merge fa1468a1f7 th/promisor-quiet-per-repo later to maint).

 * Correct use of sockaddr API in "git daemon".
   (merge 422a5bf575 st/daemon-sockaddr-fixes later to maint).

 * A memory leak in `fetch_and_setup_pack_index()` when verification of
   the downloaded pack index fails has been plugged. Also an obsolete
   `unlink()` call on parse failure has been cleaned up.

 * In t3070-wildmatch, "via ls-files" test variants with patterns
   containing backslash escapes are now skipped on Windows, avoiding 36
   test failures caused by pathspec separator conversion.
   (merge 8c84e6802c kk/wildmatch-windows-ls-files-prereq later to maint).

 * A linker warning on macOS when building with Xcode 16.3 or newer has
   been avoided by passing -fno-common to the compiler when a
   sufficiently new linker is detected.
   (merge 5cd4d0d850 hn/macos-linker-warning later to maint).

 * Other code cleanup, docfix, build fix, etc.
