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..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= 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 "__" to typeset the word inside a pair of 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=", 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 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). * Other code cleanup, docfix, build fix, etc. (merge f0e578c69c rs/use-xstrncmpz later to maint).
