Git 2.31 Release Notes ====================== Updates since v2.30 ------------------- Backward incompatible and other important changes * The "pack-redundant" command, which has been left stale with almost unusable performance issues, now warns loudly when it gets used, as we no longer want to recommend its use (instead just "repack -d" instead). * The development community has adopted Contributor Covenant v2.0 to update from v1.4 that we have been using. UI, Workflows & Features * The "--format=%(trailers)" mechanism gets enhanced to make it easier to design output for machine consumption. * When a user does not tell "git pull" to use rebase or merge, the command gives a loud message telling a user to choose between rebase or merge but creates a merge anyway, forcing users who would want to rebase to redo the operation. Fix an early part of this problem by tightening the condition to give the message---there is no reason to stop or force the user to choose between rebase or merge if the history fast-forwards. * The configuration variable 'core.abbrev' can be set to 'no' to force no abbreviation regardless of the hash algorithm. * "git rev-parse" can be explicitly told to give output as absolute or relative path with the `--path-format=(absolute|relative)` option. * Bash completion (in contrib/) update to make it easier for end-users to add completion for their custom "git" subcommands. * "git maintenance" learned to drive scheduled maintenance on platforms whose native scheduling methods are not 'cron'. * After expiring a reflog and making a single commit, the reflog for the branch would record a single entry that knows both @{0} and @{1}, but we failed to answer "what commit were we on?", i.e. @{1} * "git bundle" learns "--stdin" option to read its refs from the standard input. Also, it now does not lose refs whey they point at the same object. Performance, Internal Implementation, Development Support etc. * A 3-year old test that was not testing anything useful has been corrected. * Retire more names with "sha1" in it. * The topological walk codepath is covered by new trace2 stats. * Update the Code-of-conduct to version 2.0 from the upstream (we've been using version 1.4). * "git mktag" validates its input using its own rules before writing a tag object---it has been updated to share the logic with "git fsck". * Two new ways to feed configuration variable-value pairs via environment variables have been introduced, and the way GIT_CONFIG_PARAMETERS encodes variable/value pairs has been tweaked to make it more robust. * Tests have been updated so that they do not to get affected by the name of the default branch "git init" creates. * "git fetch" learns to treat ref updates atomically in all-or-none fashion, just like "git push" does, with the new "--atomic" option. * The peel_ref() API has been replaced with peel_iterated_oid(). * The .use_shell flag in struct child_process that is passed to run_command() API has been clarified with a bit more documentation. Fixes since v2.30 ----------------- * Diagnose command line error of "git rebase" early. (merge ca5120c339 rs/rebase-commit-validation later to maint). * Clean up option descriptions in "git cmd --help". (merge e73fe3dd02 zh/arg-help-format later to maint). * "git stash" did not work well in a sparsely checked out working tree. (merge ba359fd507 en/stash-apply-sparse-checkout later to maint). * Some tests expect that "ls -l" output has either '-' or 'x' for group executable bit, but setgid bit can be inherited from parent directory and make these fields 'S' or 's' instead, causing test failures. (merge ea8bbf2a4e mt/t4129-with-setgid-dir later to maint). * "git for-each-repo --config= " should not run for any repository when the configuration variable is not defined even once. (merge 6c62f01552 ds/for-each-repo-noopfix later to maint). * Fix 2.29 regression where "git mergetool --tool-help" fails to list all the available tools. (merge 80f5a16798 pb/mergetool-tool-help-fix later to maint). * Fix for procedure to building CI test environment for mac. (merge 3831132ace jc/macos-install-dependencies-fix later to maint). * The implementation of "git branch --sort" wrt the detached HEAD display has always been hacky, which has been cleaned up. (merge 4045f659bd ab/branch-sort later to maint). * Newline characters in the host and path part of git:// URL are now forbidden. (merge 6aed56736b jk/forbid-lf-in-git-url later to maint). * "git diff" showed a submodule working tree with untracked cruft as "Submodule commit -dirty", but a natural expectation is that the "-dirty" indicator would align with "git describe --dirty", which does not consider having untracked files in the working tree as source of dirtiness. The inconsistency has been fixed. * When more than one commit with the same patch ID appears on one side, "git log --cherry-pick A...B" did not exclude them all when a commit with the same patch ID appears on the other side. Now it does. (merge c9e3a4e76d jk/log-cherry-pick-duplicate-patches later to maint). * Documentation for "git fsck" lost stale bits that has become incorrect. (merge 28cc00a13d ab/fsck-doc-fix later to maint). * Doc fix for packfile URI feature. (merge bfc2a36ff2 jt/packfile-as-uri-doc later to maint). * Other code cleanup, docfix, build fix, etc. (merge 505a276596 pk/subsub-fetch-fix-take-2 later to maint).
