Git v2.55 Release Notes
|
|
=======================
|
|
|
|
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.
|
|
|
|
|
|
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.
|
|
|
|
|
|
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).
|
|
|
|
* Other code cleanup, docfix, build fix, etc.
|
|
(merge 80f4b802e9 ja/doc-difftool-synopsis-style later to maint).
|
|
(merge b96490241e jc/doc-timestamps-in-stat later to maint).
