Git v2.45 Release Notes
|
|
=======================
|
|
|
|
Backward Compatibility Notes
|
|
|
|
UI, Workflows & Features
|
|
|
|
* Integrate the reftable code into the refs framework as a backend.
|
|
With "git init --ref-format=reftable", hopefully it would be a lot
|
|
more efficient to manage a repository with many references.
|
|
|
|
* "git checkout -p" and friends learned that that "@" is a synonym
|
|
for "HEAD".
|
|
|
|
* Variants of vimdiff learned to honor mergetool.<variant>.layout
|
|
settings.
|
|
|
|
* "git reflog" learned a "list" subcommand that enumerates known reflogs.
|
|
|
|
* When a merge conflicted at a submodule, merge-ort backend used to
|
|
unconditionally give a lengthy message to suggest how to resolve
|
|
it. Now the message can be squelched as an advice message.
|
|
|
|
* "git for-each-ref" learned "--include-root-refs" option to show
|
|
even the stuff outside the 'refs/' hierarchy.
|
|
|
|
* "git rev-list --missing=print" has learned to optionally take
|
|
"--allow-missing-tips", which allows the objects at the starting
|
|
points to be missing.
|
|
|
|
* "git merge-tree" has learned that the three trees involved in the
|
|
3-way merge only need to be trees, not necessarily commits.
|
|
|
|
* "git log --merge" learned to pay attention to CHERRY_PICK_HEAD and
|
|
other kinds of *_HEAD pseudorefs.
|
|
|
|
* Platform specific tweaks for OS/390 has been added to
|
|
config.mak.uname.
|
|
|
|
* Users with safe.bareRepository=explicit can still work from within
|
|
$GIT_DIR of a seconary worktree (which resides at .git/worktrees/$name/)
|
|
of the primary worktree without explicitly specifying the $GIT_DIR
|
|
environment variable or the --git-dir=<path> option.
|
|
|
|
* The output format for dates "iso-strict" has been tweaked to show
|
|
a time in the Zulu timezone with "Z" suffix, instead of "+00:00".
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
|
|
* The code to iterate over refs with the reftable backend has seen
|
|
some optimization.
|
|
|
|
* More tests that are marked as "ref-files only" have been updated to
|
|
improve test coverage of reftable backend.
|
|
|
|
* Some parts of command line completion script (in contrib/) have
|
|
been micro-optimized.
|
|
|
|
* The way placeholders are to be marked-up in documentation have been
|
|
specified; use "_<placeholder>_" to typeset the word inside a pair
|
|
of <angle-brakets> emphasized.
|
|
|
|
* "git --no-lazy-fetch cmd" allows to run "cmd" while disabling lazy
|
|
fetching of objects from the promisor remote, which may be handy
|
|
for debugging.
|
|
|
|
* The implementation in "git clean" that makes "-n" and "-i" ignore
|
|
clean.requireForce has been simplified, together with the
|
|
documentation.
|
|
|
|
* The code to iterate over refs with the reftable backend has seen
|
|
some optimization.
|
|
|
|
* Uses of xwrite() helper have been audited and updated for better
|
|
error checking and simpler code.
|
|
|
|
* Some trace2 events that lacked def_param have learned to show it,
|
|
enriching the output.
|
|
|
|
* The parse-options code that deals with abbreviated long option
|
|
names have been cleaned up.
|
|
|
|
* The code in reftable backend that creates new table files works
|
|
better with the tempfile framework to avoid leaving cruft after a
|
|
failure.
|
|
|
|
* The reftable code has its own custom binary search function whose
|
|
comparison callback has an unusual interface, which caused the
|
|
binary search to degenerate into a linear search, which has been
|
|
corrected.
|
|
|
|
* The code to iterate over reflogs in the reftable has been optimized
|
|
to reduce memory allocation and deallocation.
|
|
|
|
|
|
Fixes since v2.44
|
|
-----------------
|
|
|
|
* "git apply" on a filesystem without filemode support have learned
|
|
to take a hint from what is in the index for the path, even when
|
|
not working with the "--index" or "--cached" option, when checking
|
|
the executable bit match what is required by the preimage in the
|
|
patch.
|
|
(merge 45b625142d cp/apply-core-filemode later to maint).
|
|
|
|
* "git column" has been taught to reject negative padding value, as
|
|
it would lead to nonsense behaviour including division by zero.
|
|
(merge 76fb807faa kh/column-reject-negative-padding later to maint).
|
|
|
|
* "git am --help" now tells readers what actions are available in
|
|
"git am --whitespace=<action>", in addition to saying that the
|
|
option is passed through to the underlying "git apply".
|
|
(merge a171dac734 jc/am-whitespace-doc later to maint).
|
|
|
|
* "git tag --column" failed to check the exit status of its "git
|
|
column" invocation, which has been corrected.
|
|
(merge 92e66478fc rj/tag-column-fix later to maint).
|
|
|
|
* Credential helper based on libsecret (in contrib/) has been updated
|
|
to handle an empty password correctly.
|
|
(merge 8f1f2023b7 mh/libsecret-empty-password-fix later to maint).
|
|
|
|
* "git difftool --dir-diff" learned to honor the "--trust-exit-code"
|
|
option; it used to always exit with 0 and signalled success.
|
|
(merge eb84c8b6ce ps/difftool-dir-diff-exit-code later to maint).
|
|
|
|
* The code incorrectly attempted to use textconv cache when asked,
|
|
even when we are not running in a repository, which has been
|
|
corrected.
|
|
(merge affe355fe7 jk/textconv-cache-outside-repo-fix later to maint).
|
|
|
|
* Remove an empty file that shouldn't have been added in the first
|
|
place.
|
|
(merge 4f66942215 js/remove-cruft-files later to maint).
|
|
|
|
* The logic to access reflog entries by date and number had ugly
|
|
corner cases at the boundaries, which have been cleaned up.
|
|
(merge 5edd126720 jk/reflog-special-cases-fix later to maint).
|
|
|
|
* An error message from "git upload-pack", which responds to "git
|
|
fetch" requests, had a trialing NUL in it, which has been
|
|
corrected.
|
|
(merge 3f4c7a0805 sg/upload-pack-error-message-fix later to maint).
|
|
|
|
* Clarify wording in the CodingGuidelines that requires <git-compat-util.h>
|
|
to be the first header file.
|
|
(merge 4e89f0e07c jc/doc-compat-util later to maint).
|
|
|
|
* "git commit -v --cleanup=scissors" used to add the scissors line
|
|
twice in the log message buffer, which has been corrected.
|
|
(merge e90cc075cc jt/commit-redundant-scissors-fix later to maint).
|
|
|
|
* A custom remote helper no longer cannot access the newly created
|
|
repository during "git clone", which is a regression in Git 2.44.
|
|
This has been corrected.
|
|
(merge 199f44cb2e ps/remote-helper-repo-initialization-fix later to maint).
|
|
|
|
* Various parts of upload-pack has been updated to bound the resource
|
|
consumption relative to the size of the repository to protect from
|
|
abusive clients.
|
|
(merge 6cd05e768b jk/upload-pack-bounded-resources later to maint).
|
|
|
|
* The upload-pack program, when talking over v2, accepted the
|
|
packfile-uris protocol extension from the client, even if it did
|
|
not advertise the capability, which has been corrected.
|
|
(merge a922bfa3b5 jk/upload-pack-v2-capability-cleanup later to maint).
|
|
|
|
* Make sure failure return from merge_bases_many() is properly caught.
|
|
(merge 25fd20eb44 js/merge-base-with-missing-commit later to maint).
|
|
|
|
* FSMonitor client code was confused when FSEvents were given in a
|
|
different case on a case-insensitive filesystem, which has been
|
|
corrected.
|
|
(merge 29c139ce78 jh/fsmonitor-icase-corner-case-fix later to maint).
|
|
|
|
* The "core.commentChar" configuration variable only allows an ASCII
|
|
character, which was not clearly documented, which has been
|
|
corrected.
|
|
(merge fb7c556f58 kh/doc-commentchar-is-a-byte later to maint).
|
|
|
|
* With release 2.44 we got rid of all uses of test_i18ngrep and there
|
|
is no in-flight topic that adds a new use of it. Make a call to
|
|
test_i18ngrep a hard failure, so that we can remove it at the end
|
|
of this release cycle.
|
|
(merge 381a83dfa3 jc/test-i18ngrep later to maint).
|
|
|
|
* The command line completion script (in contrib/) learned to
|
|
complete "git reflog" better.
|
|
(merge 1284f9cc11 rj/complete-reflog later to maint).
|
|
|
|
* The logic to complete the command line arguments to "git worktree"
|
|
subcommand (in contrib/) has been updated to correctly honor things
|
|
like "git -C dir" etc.
|
|
(merge 3574816d98 rj/complete-worktree-paths-fix later to maint).
|
|
|
|
* When git refuses to create a branch because the proposed branch
|
|
name is not a valid refname, an advice message is given to refer
|
|
the user to exact naming rules.
|
|
(merge 8fbd903e58 kh/branch-ref-syntax-advice later to maint).
|
|
|
|
* Code simplification by getting rid of code that sets an environment
|
|
variable that is no longer used.
|
|
(merge 72a8d3f027 pw/rebase-i-ignore-cherry-pick-help-environment later to maint).
|
|
|
|
* The code to find the effective end of log message can fall into an
|
|
endless loop, which has been corrected.
|
|
(merge 2541cba2d6 fs/find-end-of-log-message-fix later to maint).
|
|
|
|
* Mark-ups used in the documentation has been improved for
|
|
consistency.
|
|
(merge 45d5ed3e50 ja/doc-markup-fixes later to maint).
|
|
|
|
* The status.showUntrackedFiles configuration variable was
|
|
incorrectly documented to accept "false", which has been corrected.

|
|
(merge 2f64da0790 rj/restore-plug-leaks later to maint).
|

|
|

|
|
(merge b3b57c69da js/bugreport-no-suffix-fix later to maint).
|
|
|
|
* The documentation for "%(trailers[:options])" placeholder in the
|
|
"--pretty" option of commands in the "git log" family has been
|
|
updated.
|
|
(merge bff85a338c bl/doc-key-val-sep-fix later to maint).
|
|
|
|
* Other code cleanup, docfix, build fix, etc.
