| Git v2.44 Release Notes |
| ======================= |
| |
| Backward Compatibility Notes |
| |
| * "git checkout -B <branch>" used to allow switching to a branch that |
| is in use on another worktree, but this was by mistake. The users |
| need to use "--ignore-other-worktrees" option. |
| |
| |
| UI, Workflows & Features |
| |
| * "git add" and "git stash" learned to support the ":(attr:...)" |
| magic pathspec. |
| |
| * "git rebase --autosquash" is now enabled for non-interactive rebase, |
| but it is still incompatible with the apply backend. |
| |
| * Introduce "git replay", a tool meant on the server side without |
| working tree to recreate a history. |
| |
| * "git merge-file" learned to take the "--diff-algorithm" option to |
| use algorithm different from the default "myers" diff. |
| |
| * Command line completion (in contrib/) learned to complete path |
| arguments to the "add/set" subcommands of "git sparse-checkout" |
| better. |
| |
| * "git checkout -B <branch> [<start-point>]" allowed a branch that is |
| in use in another worktree to be updated and checked out, which |
| might be a bit unexpected. The rule has been tightened, which is a |
| breaking change. "--ignore-other-worktrees" option is required to |
| unbreak you, if you are used to the current behaviour that "-B" |
| overrides the safety. |
| |
| * The builtin_objectmode attribute is populated for each path |
| without adding anything in .gitattributes files, which would be |
| useful in magic pathspec, e.g., ":(attr:builtin_objectmode=100755)" |
| to limit to executables. |
| |
| * "git fetch" learned to pay attention to "fetch.all" configuration |
| variable, which pretends as if "--all" was passed from the command |
| line when no remote parameter was given. |
| |
| * In addition to (rather cryptic) Security Identifiers, show username |
| and domain in the error message when we barf on mismatch between |
| the Git directory and the current user on Windows. |
| |
| * The error message given when "git branch -d branch" fails due to |
| commits unique to the branch has been split into an error and a new |
| conditional advice message. |
| |
| * When given an existing but unreadable file as a configuration file, |
| gitweb behaved as if the file did not exist at all, but now it |
| errors out. This is a change that may break backward compatibility. |
| |
| * When $HOME/.gitconfig is missing but XDG config file is available, we |
| should write into the latter, not former. "git gc" and "git |
| maintenance" wrote into a wrong "global config" file, which have |
| been corrected. |
| |
| * Define "special ref" as a very narrow set that consists of |
| FETCH_HEAD and MERGE_HEAD, and clarify everything else that used to |
| be classified as such are actually just pseudorefs. |
| |
| * All conditional "advice" messages show how to turn them off, which |
| becomes repetitive. Setting advice.* configuration explicitly on |
| now omits the instruction part. |
| |
| * The "disable repository discovery of a bare repository" check, |
| triggered by setting safe.bareRepository configuration variable to |
| 'explicit', has been loosened to exclude the ".git/" directory inside |
| a non-bare repository from the check. So you can do "cd .git && |
| git cmd" to run a Git command that works on a bare repository without |
| explicitly specifying $GIT_DIR now. |
| |
| * The completion script (in contrib/) learned more options that can |
| be used with "git log". |
| |
| * The labels on conflict markers for the common ancestor, our version, |
| and the other version are available to custom 3-way merge driver |
| via %S, %X, and %Y placeholders. |
| |
| * The write codepath for the reftable data learned to honor |
| core.fsync configuration. |
| |
| * The "--fsck-objects" option of "git index-pack" now can take the |
| optional parameter to tweak severity of different fsck errors. |
| |
| * The wincred credential backend has been taught to support oauth |
| refresh token the same way as credential-cache and |
| credential-libsecret backends. |
| |
| * Command line completion support (in contrib/) has been |
| updated for "git bisect". |
| |
| * "git branch" and friends learned to use the formatted text as |
| sorting key, not the underlying timestamp value, when the --sort |
| option is used with author or committer timestamp with a format |
| specifier (e.g., "--sort=creatordate:format:%H:%M:%S"). |
| |
| * The command line completion script (in contrib/) learned to |
| complete configuration variable names better. |
| |
| |
| Performance, Internal Implementation, Development Support etc. |
| |
| * Process to add some form of low-level unit tests has started. |
| |
| * Add support for GitLab CI. |
| |
| * "git for-each-ref --no-sort" still sorted the refs alphabetically |
| which paid non-trivial cost. It has been redefined to show output |
| in an unspecified order, to allow certain optimizations to take |
| advantage of. |
| |
| * Simplify API implementation to delete references by eliminating |
| duplication. |
| |
| * Subject approxidate() and show_date() machinery to OSS-Fuzz. |
| |
| * A new helper to let us pretend that we called lstat() when we know |
| our cache_entry is up-to-date via fsmonitor. |
| |
| * The optimization based on fsmonitor in the "diff --cached" |
| codepath is resurrected with the "fake-lstat" introduced earlier. |
| |
| * Test balloon to use C99 "bool" type from <stdbool.h> has been |
| added. |
| |
| * "git clone" has been prepared to allow cloning a repository with |
| non-default hash function into a repository that uses the reftable |
| backend. |
| |
| * Streaming spans of packfile data used to be done only from a |
| single, primary, pack in a repository with multiple packfiles. It |
| has been extended to allow reuse from other packfiles, too. |
| |
| * Comment updates to help developers not to attempt to modify |
| messages from plumbing commands that must stay constant. |
| |
| It might make sense to reassess the plumbing needs every few years, |
| but that should be done as a separate effort. |
| |
| * Move test-ctype helper to the unit-test framework. |
| |
| * Instead of manually creating refs/ hierarchy on disk upon a |
| creation of a secondary worktree, which is only usable via the |
| files backend, use the refs API to populate it. |
| |
| * CI for GitLab learned to drive macOS jobs. |
| |
| * A few tests to "git commit -o <pathspec>" and "git commit -i |
| <pathspec>" has been added. |
| |
| * Tests on ref API are moved around to prepare for reftable. |
| |
| * The Makefile often had to say "-L$(path) -R$(path)" that repeats |
| the path to the same library directory for link time and runtime. |
| A Makefile template is used to reduce such repetition. |
| |
| * The priority queue test has been migrated to the unit testing |
| framework. |
| |
| * Setting `feature.experimental` opts the user into multi-pack reuse |
| experiment |
| |
| * Squelch node.js 16 deprecation warnings from GitHub Actions CI |
| by updating actions/github-script and actions/checkout that use |
| node.js 20. |
| |
| * The mechanism to report the filename in the source code, used by |
| the unit-test machinery, assumed that the compiler expanded __FILE__ |
| to the path to the source given to the $(CC), but some compilers |
| give full path, breaking the output. This has been corrected. |
| |
| |
| Fixes since v2.43 |
| ----------------- |
| |
| * The way CI testing used "prove" could lead to running the test |
| suite twice needlessly, which has been corrected. |
| |
| * Update ref-related tests. |
| |
| * "git format-patch --encode-email-headers" ignored the option when |
| preparing the cover letter, which has been corrected. |
| |
| * Newer versions of Getopt::Long started giving warnings against our |
| (ab)use of it in "git send-email". Bump the minimum version |
| requirement for Perl to 5.8.1 (from September 2002) to allow |
| simplifying our implementation. |
| |
| * Earlier we stopped relying on commit-graph that (still) records |
| information about commits that are lost from the object store, |
| which has negative performance implications. The default has been |
| flipped to disable this pessimization. |
| |
| * Stale URLs have been updated to their current counterparts (or |
| archive.org) and HTTP links are replaced with working HTTPS links. |
| |
| * trace2 streams used to record the URLs that potentially embed |
| authentication material, which has been corrected. |
| |
| * The sample pre-commit hook that tries to catch introduction of new |
| paths that use potentially non-portable characters did not notice |
| an existing path getting renamed to such a problematic path, when |
| rename detection was enabled. |
| |
| * The command line parser for the "log" family of commands was too |
| loose when parsing certain numbers, e.g., silently ignoring the |
| extra 'q' in "git log -n 1q" without complaining, which has been |
| tightened up. |
| |
| * "git $cmd --end-of-options --rev -- --path" for some $cmd failed |
| to interpret "--rev" as a rev, and "--path" as a path. This was |
| fixed for many programs like "reset" and "checkout". |
| |
| * "git bisect reset" has been taught to clean up state files and refs |
| even when BISECT_START file is gone. |
| |
| * Some codepaths did not correctly parse configuration variables |
| specified with valueless "true", which has been corrected. |
| |
| * Code clean-up for sanity checking of command line options for "git |
| show-ref". |
| |
| * The code to parse the From e-mail header has been updated to avoid |
| recursion. |
| |
| * "git fetch --atomic" issued an unnecessary empty error message, |
| which has been corrected. |
| |
| * Command line completion script (in contrib/) learned to work better |
| with the reftable backend. |
| |
| * "git status" is taught to show both the branch being bisected and |
| being rebased when both are in effect at the same time. |
| |
| * "git archive --list extra garbage" silently ignored excess command |
| line parameters, which has been corrected. |
| |
| * "git sparse-checkout set" added default patterns even when the |
| patterns are being fed from the standard input, which has been |
| corrected. |
| |
| * "git sparse-checkout (add|set) --[no-]cone --end-of-options" did |
| not handle "--end-of-options" correctly after a recent update. |
| |
| * Unlike other environment variables that took the usual |
| true/false/yes/no as well as 0/1, GIT_FLUSH only understood 0/1, |
| which has been corrected. |
| |
| * Clearing in-core repository (happens during e.g., "git fetch |
| --recurse-submodules" with commit graph enabled) made in-core |
| commit object in an inconsistent state by discarding the necessary |
| data from commit-graph too early, which has been corrected. |
| |
| * Update to a new feature recently added, "git show-ref --exists". |
| |
| * oss-fuzz tests are built and run in CI. |
| (merge c4a9cf1df3 js/oss-fuzz-build-in-ci later to maint). |
| |
| * Rename detection logic ignored the final line of a file if it is an |
| incomplete line. |
| |
| * GitHub CI update. |
| (merge 0188b2c8e0 pb/ci-github-skip-logs-for-broken-tests later to maint). |
| |
| * "git diff --no-rename A B" did not disable rename detection but did |
| not trigger an error from the command line parser. |
| |
| * "git archive --remote=<remote>" learned to talk over the smart |
| http (aka stateless) transport. |
| (merge 176cd68634 jx/remote-archive-over-smart-http later to maint). |
| |
| * Fetching via protocol v0 over Smart HTTP transport sometimes failed |
| to correctly auto-follow tags. |
| (merge fba732c462 jk/fetch-auto-tag-following-fix later to maint). |
| |
| * The documentation for the --exclude-per-directory option marked it |
| as deprecated, which confused readers into thinking there may be a |
| plan to remove it in the future, which was not our intention. |
| (merge 0009542cab jc/ls-files-doc-update later to maint). |
| |
| * "git diff --no-index file1 file2" segfaulted while invoking the |
| external diff driver, which has been corrected. |
| |
| * Rewrite //-comments to /* comments */ in files whose comments |
| prevalently use the latter. |
| |
| * Cirrus CI jobs started breaking because we specified version of |
| FreeBSD that is no longer available, which has been corrected. |
| (merge 81fffb66d3 cb/use-freebsd-13-2-at-cirrus-ci later to maint). |
| |
| * A caller called index_file_exists() that takes a string expressed |
| as <ptr, length> with a wrong length, which has been corrected. |
| (merge 156e28b36d jh/sparse-index-expand-to-path-fix later to maint). |
| |
| * A failed "git tag -s" did not necessarily result in an error |
| depending on the crypto backend, which has been corrected. |
| |
| * "git stash" sometimes was silent even when it failed due to |
| unwritable index file, which has been corrected. |
| |
| * "git show-ref --verify" did not show things like "CHERRY_PICK_HEAD", |
| which has been corrected. |
| |
| * Recent conversion to allow more than 0/1 in GIT_FLUSH broke the |
| mechanism by flipping what yes/no means by mistake, which has been |
| corrected. |
| |
| * The sequencer machinery does not use the ref API and instead |
| records names of certain objects it needs for its correct operation |
| in temporary files, which makes these objects susceptible to loss |
| by garbage collection. These temporary files have been added as |
| starting points for reachability analysis to fix this. |
| (merge bc7f5db896 pw/gc-during-rebase later to maint). |
| |
| * "git cherry-pick" invoked during "git rebase -i" session lost |
| the authorship information, which has been corrected. |
| (merge e4301f73ff vn/rebase-with-cherry-pick-authorship later to maint). |
| |
| * The code paths that call repo_read_object_file() have been |
| tightened to react to errors. |
| (merge 568459bf5e js/check-null-from-read-object-file later to maint). |
| |
| * Other code cleanup, docfix, build fix, etc. |
| (merge 5aea3955bc rj/clarify-branch-doc-m later to maint). |
| (merge 9cce3be2df bk/bisect-doc-fix later to maint). |
| (merge 8430b438f6 vd/fsck-submodule-url-test later to maint). |
| (merge 3cb4384683 jc/t0091-with-unknown-git later to maint). |
| (merge 020456cb74 rs/receive-pack-remove-find-header later to maint). |
| (merge bc47139f4f la/trailer-cleanups later to maint). |
