| 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". |
| |
| * "git diff" and friends learned two extra configuration variables, |
| diff.srcPrefix and diff.dstPrefix. |
| |
| * The status.showUntrackedFiles configuration variable had a name |
| that tempts users to set a Boolean value expressed in our usual |
| "false", "off", and "0", but it only took "no". This has been |
| corrected so "true" and its synonyms are taken as "normal", while |
| "false" and its synonyms are taken as "no". |
| |
| * Remove an ancient and not well maintained Hg-to-git migration |
| script from contrib/. |
| |
| * Hints that suggest what to do after resolving conflicts can now be |
| squelched by disabling advice.mergeConflict. |
| |
| * Allow git-cherry-pick(1) to automatically drop redundant commits via |
| a new `--empty` option, similar to the `--empty` options for |
| git-rebase(1) and git-am(1). Includes a soft deprecation of |
| `--keep-redundant-commits` as well as some related docs changes and |
| sequencer code cleanup. |
| |
| * "git config" learned "--comment=<message>" option to leave a |
| comment immediately after the "variable = value" on the same line |
| in the configuration file. |
| |
| * core.commentChar used to be limited to a single byte, but has been |
| updated to allow an arbitrary multi-byte sequence. |
| |
| * "git add -p" and other "interactive hunk selection" UI has learned to |
| skip showing the hunk immediately after it has already been shown, and |
| an additional action to explicitly ask to reshow the current hunk. |
| |
| * "git pack-refs" learned the "--auto" option, which is a useful |
| addition to be triggered from "git gc --auto". |
| |
| * "git add -u <pathspec>" and "git commit [-i] <pathspec>" did not |
| diagnose a pathspec element that did not match any files in certain |
| situations, unlike "git add <pathspec>" did. |
| |
| * The userdiff patterns for C# has been updated. |
| |
| |
| 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. |
| |
| * Work to support a repository that work with both SHA-1 and SHA-256 |
| hash algorithms has started. |
| |
| * A new fuzz target that exercises config parsing code has been |
| added. |
| |
| * Fix the way recently added tests interpolate variables defined |
| outside them, and document the best practice to help future |
| developers. |
| |
| * Introduce an experimental protocol for contributors to propose the |
| topic description to be used in the "What's cooking" report, the |
| merge commit message for the topic, and in the release notes and |
| document it in the SubmittingPatches document. |
| |
| * The t/README file now gives a hint on running individual tests in |
| the "t/" directory with "make t<num>-*.sh t<num>-*.sh". |
| (merge 8d383806fc pb/test-scripts-are-build-targets later to maint). |
| |
| * The "hint:" messages given by the advice mechanism, when given a |
| message with a blank line, left a line with trailing whitespace, |
| which has been cleansed. |
| |
| * Documentation rules has been explicitly described how to mark-up |
| literal parts and a few manual pages have been updated as examples. |
| |
| * The .editorconfig file has been taught that a Makefile uses HT |
| indentation. |
| |
| * t-prio-queue test has been cleaned up by using C99 compound |
| literals; this is meant to also serve as a weather-balloon to smoke |
| out folks with compilers who have trouble compiling code that uses |
| the feature. |
| |
| * Windows binary used to decide the use of unix-domain socket at |
| build time, but it learned to make the decision at runtime instead. |
| |
| * The "shared repository" test in the t0610 reftable test failed |
| under restrictive umask setting (e.g. 007), which has been |
| corrected. |
| |
| * Document and apply workaround for a buggy version of dash that |
| mishandles "local var=val" construct. |
| |
| * The codepaths that reach date_mode_from_type() have been updated to |
| pass "struct date_mode" by value to make them thread safe. |
| |
| * The strategy to compact multiple tables of reftables after many |
| operations accumulate many entries has been improved to avoid |
| accumulating too many tables uncollected. |
| |
| |
| 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. |
| |
| * Leaks from "git restore" have been plugged. |
| (merge 2f64da0790 rj/restore-plug-leaks later to maint). |
| |
| * "git bugreport --no-suffix" was not supported and instead |
| segfaulted, which has been corrected. |
| (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). |
| |
| * "git checkout --conflict=bad" reported a bad conflictStyle as if it |
| were given to a configuration variable; it has been corrected to |
| report that the command line option is bad. |
| (merge 5a99c1ac1a pw/checkout-conflict-errorfix later to maint). |
| |
| * Code clean-up in the "git log" machinery that implements custom log |
| message formatting. |
| (merge 1c10b8e5b0 jk/pretty-subject-cleanup later to maint). |
| |
| * "git config" corrupted literal HT characters written in the |
| configuration file as part of a value, which has been corrected. |
| (merge e6895c3f97 ds/config-internal-whitespace-fix later to maint). |
| |
| * A unit test for reftable code tried to enumerate all files in a |
| directory after reftable operations and expected to see nothing but |
| the files it wanted to leave there, but was fooled by .nfs* cruft |
| files left, which has been corrected. |
| (merge 0068aa7946 ps/reftable-unit-test-nfs-workaround later to maint). |
| |
| * The implementation and documentation of "object-format" option |
| exchange between the Git itself and its remote helpers did not |
| quite match, which has been corrected. |
| |
| * The "--pretty=<shortHand>" option of the commands in the "git log" |
| family, defined as "[pretty] shortHand = <expansion>" should have |
| been looked up case insensitively, but was not, which has been |
| corrected. |
| (merge f999d5188b bl/pretty-shorthand-config-fix later to maint). |
| |
| * "git apply" failed to extract the filename the patch applied to, |
| when the change was about an empty file created in or deleted from |
| a directory whose name ends with a SP, which has been corrected. |
| (merge 776ffd1a30 jc/apply-parse-diff-git-header-names-fix later to maint). |
| |
| * Update a more recent tutorial doc. |
| (merge 95ab557b4b dg/myfirstobjectwalk-updates later to maint). |
| |
| * The test script had an incomplete and ineffective attempt to avoid |
| clobbering the testing user's real crontab (and its equivalents), |
| which has been completed. |
| (merge 73cb87773b es/test-cron-safety later to maint). |
| |
| * Use advice_if_enabled() API to rewrite a simple pattern to |
| call advise() after checking advice_enabled(). |
| (merge 6412d01527 rj/use-adv-if-enabled later to maint). |
| |
| * Another "set -u" fix for the bash prompt (in contrib/) script. |
| (merge d7805bc743 vs/complete-with-set-u-fix later to maint). |
| |
| * "git checkout/switch --detach foo", after switching to the detached |
| HEAD state, gave the tracking information for the 'foo' branch, |
| which was pointless. |
| |
| * "git apply" has been updated to lift the hardcoded pathname length |
| limit, which in turn allowed a mksnpath() function that is no |
| longer used. |
| (merge 708f7e0590 rs/apply-lift-path-length-limit later to maint). |
| |
| * A file descriptor leak in an error codepath, used when "git apply |
| --reject" fails to create the *.rej file, has been corrected. |
| (merge 2b1f456adf rs/apply-reject-fd-leakfix later to maint). |
| |
| * A config parser callback function fell through instead of returning |
| after recognising and processing a variable, wasting cycles, which |
| has been corrected. |
| (merge a816ccd642 ds/fetch-config-parse-microfix later to maint). |
| |
| * Fix was added to work around a regression in libcURL 8.7.0 (which has |
| already been fixed in their tip of the tree). |
| (merge 92a209bf24 jk/libcurl-8.7-regression-workaround later to maint). |
| |
| * The variable that holds the value read from the core.excludefile |
| configuration variable used to leak, which has been corrected. |
| (merge 0e0fefb29f jc/unleak-core-excludesfile later to maint). |
| |
| * vreportf(), which is usede by error() and friends, has been taught |
| to give the error message printf-format string when its vsnprintf() |
| call fails, instead of showing nothing useful to identify the |
| nature of the error. |
| (merge c63adab961 rs/usage-fallback-to-show-message-format later to maint). |
| |
| * Adjust to an upcoming changes to GNU make that breaks our Makefiles. |
| (merge 227b8fd902 tb/make-indent-conditional-with-non-spaces later to maint). |
| |
| * Other code cleanup, docfix, build fix, etc. |
| (merge f0e578c69c rs/use-xstrncmpz later to maint). |
| (merge 83e6eb7d7a ba/credential-test-clean-fix later to maint). |
