Git 2.23 Release Notes ====================== Updates since v2.22 ------------------- Backward compatibility note * The "--base" option of "format-patch" computed the patch-ids for prerequisite patches in an unstable way, which has been updated to compute in a way that is compatible with "git patch-id --stable". UI, Workflows & Features * The "git fast-export/import" pair has been taught to handle commits with log messages in encoding other than UTF-8 better. * In recent versions of Git, per-worktree refs are exposed in refs/worktrees// hierarchy, which means that worktree names must be a valid refname component. The code now sanitizes the names given to worktrees, to make sure these refs are well-formed. * "git merge" learned "--quit" option that cleans up the in-progress merge while leaving the working tree and the index still in a mess. * "git format-patch" learns a configuration to set the default for its --notes= option. * The code to show args with potential typo that cannot be interpreted as a commit-ish has been improved. * "git clone --recurse-submodules" learned to set up the submodules to ignore commit object names recorded in the superproject gitlink and instead use the commits that happen to be at the tip of the remote-tracking branches from the get-go, by passing the new "--remote-submodules" option. * The pattern "git diff/grep" use to extract funcname and words boundary for Matlab has been extend to cover Octave, which is more or less equivalent. * "git help git" was hard to discover (well, at least for some people). * The pattern "git diff/grep" use to extract funcname and words boundary for Rust has been added. * "git status" can be told a non-standard default value for the "--[no-]ahead-behind" option with a new configuration variable status.aheadBehind. * "git fetch" and "git pull" reports when a fetch results in non-fast-forward updates to let the user notice unusual situation. The commands learned "--no-shown-forced-updates" option to disable this safety feature. * Two new commands "git switch" and "git restore" are introduced to split "checking out a branch to work on advancing its history" and "checking out paths out of the index and/or a tree-ish to work on advancing the current history" out of the single "git checkout" command. * "git branch --list" learned to always output the detached HEAD as the first item (when the HEAD is detached, of course), regardless of the locale. * The conditional inclusion mechanism learned to base the choice on the branch the HEAD currently is on. * "git rev-list --objects" learned with "--no-object-names" option to squelch the path to the object that is used as a grouping hint for pack-objects. * A new tag.gpgSign configuration variable turns "git tag -a" into "git tag -s". Performance, Internal Implementation, Development Support etc. * Update supporting parts of "git rebase" to remove code that should no longer be used. * Developer support to emulate unsatisfied prerequisites in tests to ensure that the remainer of the tests still succeeds when tests with prerequisites are skipped. * "git update-server-info" learned not to rewrite the file with the same contents. * The way of specifying the path to find dynamic libraries at runtime has been simplified. The old default to pass -R/path/to/dir has been replaced with the new default to pass -Wl,-rpath,/path/to/dir, which is the more recent GCC uses. Those who need to build with an old GCC can still use "CC_LD_DYNPATH=-R" * Prepare use of reachability index in topological walker that works on a range (A..B). * A new tutorial targetting specifically aspiring git-core developers has been added. * Auto-detect how to tell HP-UX aCC where to use dynamically linked libraries from at runtime. * "git mergetool" and its tests now spawn fewer subprocesses. * Dev support update to help tracing out tests. * Support to build with MSVC has been updated. * "git fetch" that grabs from a group of remotes learned to run the auto-gc only once at the very end. * A handful of Windows build patches have been upstreamed. Fixes since v2.22 ----------------- * A relative pathname given to "git init --template= " ought to be relative to the directory "git init" gets invoked in, but it instead was made relative to the repository, which has been corrected. (merge e1df7fe43f nd/init-relative-template-fix later to maint). * "git worktree add" used to fail when another worktree connected to the same repository was corrupt, which has been corrected. (merge 105df73e71 nd/corrupt-worktrees later to maint). * The ownership rule for the file descriptor to fast-import remote backend was mixed up, leading to unrelated file descriptor getting closed, which has been fixed. (merge 3203566a71 mh/import-transport-fd-fix later to maint). * A "merge -c" instruction during "git rebase --rebase-merges" should give the user a chance to edit the log message, even when there is otherwise no need to create a new merge and replace the existing one (i.e. fast-forward instead), but did not. Which has been corrected. * Code cleanup and futureproof. (merge 31f5256c82 ds/object-info-for-prefetch-fix later to maint). * More parameter validation. (merge de99eb0c24 es/grep-require-name-when-needed later to maint). * "git update-server-info" used to leave stale packfiles in its output, which has been corrected. (merge e941c48d49 ew/server-info-remove-crufts later to maint). * The server side support for "git fetch" used to show incorrect value for the HEAD symbolic ref when the namespace feature is in use, which has been corrected. (merge 533e088250 jk/HEAD-symref-in-xfer-namespaces later to maint). * "git am -i --resolved" segfaulted after trying to see a commit as if it were a tree, which has been corrected. (merge 7663e438c5 jk/am-i-resolved-fix later to maint). * "git bundle verify" needs to see if prerequisite objects exist in the receiving repository, but the command did not check if we are in a repository upfront, which has been corrected. (merge 3bbbe467f2 js/bundle-verify-require-object-store later to maint). * "git merge --squash" is designed to update the working tree and the index without creating the commit, and this cannot be countermanded by adding the "--commit" option; the command now refuses to work when both options are given. (merge 1d14d0c994 vv/merge-squash-with-explicit-commit later to maint). * The data collected by fsmonitor was not properly written back to the on-disk index file, breaking t7519 tests occasionally, which has been corrected. (merge b5a8169752 js/fsmonitor-unflake later to maint). * Update to Unicode 12.1 width table. (merge 5817f9caa3 bb/unicode-12.1-reiwa later to maint). * The command line to invoke a "git cat-file" command from inside "git p4" was not properly quoted to protect a caret and running a broken command on Windows, which has been corrected. (merge c3f2358de3 mm/p4-unshelve-windows-fix later to maint). * "git request-pull" learned to warn when the ref we ask them to pull from in the local repository and in the published repository are different. (merge 0454220d66 pb/request-pull-verify-remote-ref later to maint). * When creating a partial clone, the object filtering criteria is recorded for the origin of the clone, but this incorrectly used a hardcoded name "origin" to name that remote; it has been corrected to honor the "--origin " option. (merge 1c4a9f9114 xl/record-partial-clone-origin later to maint). * "git fetch" into a lazy clone forgot to fetch base objects that are necessary to complete delta in a thin packfile, which has been corrected. (merge 810e19322d jt/partial-clone-missing-ref-delta-base later to maint). * The filter_data used in the list-objects-filter (which manages a lazily sparse clone repository) did not use the dynamic array API correctly---'nr' is supposed to point at one past the last element of the array in use. This has been corrected. (merge 7140600e2e md/list-objects-filter-memfix later to maint). * The description about slashes in gitignore patterns (used to indicate things like "anchored to this level only" and "only matches directories") has been revamped. (merge 1a58bad014 an/ignore-doc-update later to maint). * The URL decoding code has been updated to avoid going past the end of the string while parsing %-- sequence. (merge d37dc239a4 md/url-parse-harden later to maint). * The list of for-each like macros used by clang-format has been updated. (merge fc7e03aace mo/clang-format-for-each-update later to maint). * "git branch --list" learned to show branches that are checked out in other worktrees connected to the same repository prefixed with '+', similar to the way the currently checked out branch is shown with '*' in front. (merge 6e9381469e nb/branch-show-other-worktrees-head later to maint). * Code restructuring during 2.20 period broke fetching tags via "import" based transports. (merge f80d922355 fc/fetch-with-import-fix later to maint). * The commit-graph file is now part of the "files that the runtime may keep open file descriptors on, all of which would need to be closed when done with the object store", and the file descriptor to an existing commit-graph file now is closed before "gc" finalizes a new instance to replace it. (merge 2d511cfc0b ds/close-object-store later to maint). * "git checkout -p" needs to selectively apply a patch in reverse, which did not work well. (merge 2bd69b9024 pw/add-p-recount later to maint). * Code clean-up to avoid signed integer wraparounds during binary search. (merge 568a05c5ec rs/avoid-overflow-in-midpoint-computation later to maint). * "git interpret-trailers" always treated '#' as the comment character, regardless of core.commentChar setting, which has been corrected. (merge 29c83fc23f jk/trailers-use-config later to maint). * "git stash show 23" used to work, but no more after getting rewritten in C; this regression has been corrected. (merge 63b50c8ffe tg/stash-ref-by-index-fix later to maint). * "git rebase --abort" used to leave refs/rewritten/ when concluding "git rebase -r", which has been corrected. (merge d559f502c5 pw/rebase-abort-clean-rewritten later to maint). * An incorrect list of options was cached after command line completion failed (e.g. trying to complete a command that requires a repository outside one), which has been corrected. (merge 69702523af nd/completion-no-cache-failure later to maint). * The code to parse scaled numbers out of configuration files has been made more robust and also easier to follow. (merge 39c575c969 rs/config-unit-parsing later to maint). * The codepath to compute delta islands used to spew progress output without giving the callers any way to squelch it, which has been fixed. (merge bdbdf42f8a jk/delta-islands-progress-fix later to maint). * Protocol capabilities that go over wire should never be translated, but it was incorrectly marked for translation, which has been corrected. The output of protocol capabilities for debugging has been tweaked a bit. * Use "Erase in Line" CSI sequence that is already used in the editor support to clear cruft in the progress output. (merge 5b12e3123b sg/rebase-progress later to maint). * "git submodule foreach" did not protect command line options passed to the command to be run in each submodule correctly, when the "--recursive" option was in use. (merge 30db18b148 ms/submodule-foreach-fix later to maint). * The configuration variable rebase.rescheduleFailedExec should be effective only while running an interactive rebase and should not affect anything when running an non-interactive one, which was not the case. This has been corrected. (merge 906b63942a js/rebase-reschedule-applies-only-to-interactive later to maint). * The "git clone" documentation refers to command line options in its description in the short form; they have been replaced with long forms to make them more recognisable. (merge bfc8c84ed5 qn/clone-doc-use-long-form later to maint). * Other code cleanup, docfix, build fix, etc. (merge f547101b26 es/git-debugger-doc later to maint). (merge 7877ac3d7b js/bisect-helper-check-get-oid-return-value later to maint). (merge 0108f47eb3 sw/git-p4-unshelve-branched-files later to maint).
