A new + option is added to keep digging without stopping, and instead + filter out commits with timestamp older than X. + + * "git -c branch.autosetupmerge=simple branch $A $B" will set the $B + as $A's upstream only when $A and $B shares the same name, and "git + -c push.default=simple" on branch $A would push to update the + branch $A at the remote $B came from. Also more places use the + sole remote, if exists, before defaulting to 'origin'. + + * A new doc has been added that lists tips for tools to work with + Git's codebase. + + * "git remote -v" now shows the list-objects-filter used during + fetching from the remote, if available. + + * With the new http.curloptResolve configuration, the CURLOPT_RESOLVE + mechanism that allows cURL based applications to use pre-resolved + IP addresses for the requests is exposed to the scripts. + + * "git add -i" was rewritten in C some time ago and has been in + testing; the reimplementation is now exposed to general public by + default. + + * Deprecate non-cone mode of the sparse-checkout feature. + + * Introduce a filesystem-dependent mechanism to optimize the way the + bits for many loose object files are ensured to hit the disk + platter. + + * The "do not remove the directory the user started Git in" logic, + when Git cannot tell where that directory is, is disabled. Earlier + we refused to run in such a case. + + * A mechanism to pack unreachable objects into a "cruft pack", + instead of ejecting them into loose form to be reclaimed later, has + been introduced. + + * Update the doctype written in gitweb output to xhtml5. + + * The "transfer.credentialsInURL" configuration variable controls what + happens when a URL with embedded login credential is used on either + "fetch" or "push". Credentials are currently only detected in + `remote.<name>.url` config, not `remote.<name>.pushurl`. + + * "git revert" learns "--reference" option to use more human-readable + reference to the commit it reverts in the message template it + prepares for the user. + + * Various error messages that talk about the removal of + "--preserve-merges" in "rebase" have been strengthened, and "rebase + --abort" learned to get out of a state that was left by an earlier + use of the option. + + +Performance, Internal Implementation, Development Support etc. + + * The performance of the "untracked cache" feature has been improved + when "--untracked-files=<mode>" and "status.showUntrackedFiles" + are combined. + + * "git stash" works better with sparse index entries. + + * "git show :<path>" learned to work better with the sparse-index + feature. + + * Introduce and apply coccinelle rule to discourage an explicit + comparison between a pointer and NULL, and applies the clean-up to + the maintenance track. + + * Preliminary code refactoring around transport and bundle code. + + * "sparse-checkout" learns to work better with the sparse-index + feature. + + * A workflow change for translators are being proposed. git.pot is + no longer version controlled and it is local responsibility of + translators to generate it. + + * Plug the memory leaks from the trickiest API of all, the revision + walker. + + * Rename .env_array member to .env in the child_process structure. + + * The fsmonitor--daemon handles even more corner cases when + watching filesystem events. + + * A new bug() and BUG_if_bug() API is introduced to make it easier to + uniformly log "detect multiple bugs and abort in the end" pattern. + + +Fixes since v2.36 +----------------- + + * "git submodule update" without pathspec should silently skip an + uninitialized submodule, but it started to become noisy by mistake. + (merge 4f1ccef87c gc/submodule-update-part2 later to maint). + + * "diff-tree --stdin" has been broken for about a year, but 2.36 + release broke it even worse by breaking running the command with + <pathspec>, which in turn broke "gitk" and got noticed. This has + been corrected by aligning its behaviour to that of "log". + (merge f8781bfda3 jc/diff-tree-stdin-fix later to maint). + + * Regression fix for 2.36 where "git name-rev" started to sometimes + reference strings after they are freed. + (merge 45a14f578e rs/name-rev-fix-free-after-use later to maint). + + * "git show <commit1> <commit2>... -- <pathspec>" lost the pathspec + when showing the second and subsequent commits, which has been + corrected. + (merge 5cdb38458e jc/show-pathspec-fix later to maint). + + * "git fast-export -- <pathspec>" lost the pathspec when showing the + second and subsequent commits, which has been corrected. + (merge d1c25272f5 rs/fast-export-pathspec-fix later to maint). + + * "git format-patch <args> -- <pathspec>" lost the pathspec when + showing the second and subsequent commits, which has been + corrected. + (merge 91f8f7e46f rs/format-patch-pathspec-fix later to maint). + + * "git clone --origin X" leaked piece of memory that held value read + from the clone.defaultRemoteName configuration variable, which has + been plugged. + (merge 6dfadc8981 jc/clone-remote-name-leak-fix later to maint). + + * Get rid of a bogus and over-eager coccinelle rule. + (merge 08bdd3a185 jc/cocci-xstrdup-or-null-fix later to maint). + + * The path taken by "git multi-pack-index" command from the end user + was compared with path internally prepared by the tool without first + normalizing, which lead to duplicated paths not being noticed, + which has been corrected. + (merge 11f9e8de3d ds/midx-normalize-pathname-before-comparison later to maint). + + * Correct choices of C compilers used in various CI jobs. + (merge 3506cae04f ab/cc-package-fixes later to maint). + + * Various cleanups to "git p4". + (merge 4ff0108d9e jh/p4-various-fixups later to maint). + + * The progress meter of "git blame" was showing incorrect numbers + when processing only parts of the file. + (merge e5f5d7d42e ea/progress-partial-blame later to maint). + + * "git rebase --keep-base <upstream> <branch-to-rebase>" computed the + commit to rebase onto incorrectly, which has been corrected. + (merge 9e5ebe9668 ah/rebase-keep-base-fix later to maint). + + * Fix a leak of FILE * in an error codepath. + (merge c0befa0c03 kt/commit-graph-plug-fp-leak-on-error later to maint). + + * Avoid problems from interaction between malloc_check and address + sanitizer. + (merge 067109a5e7 pw/test-malloc-with-sanitize-address later to maint). + + * The commit summary shown after making a commit is matched to what + is given in "git status" not to use the break-rewrite heuristics. + (merge 84792322ed rs/commit-summary-wo-break-rewrite later to maint). + + * Update a few end-user facing messages around EOL conversion. + (merge c970d30c2c ah/convert-warning-message later to maint). + + * Trace2 documentation updates. + (merge a6c80c313c js/trace2-doc-fixes later to maint). + + * Build procedure fixup. + (merge 1fbfd96f50 mg/detect-compiler-in-c-locale later to maint). + + * "git pull" without "--recurse-submodules=<arg>" made + submodule.recurse take precedence over fetch.recurseSubmodules by + mistake, which has been corrected. + (merge 5819417365 gc/pull-recurse-submodules later to maint). + + * "git bisect" was too silent before it is ready to start computing + the actual bisection, which has been corrected. + (merge f11046e6de cd/bisect-messages-from-pre-flight-states later to maint). + + * macOS CI jobs have been occasionally flaky due to tentative version + skew between perforce and the homebrew packager. Instead of + failing the whole CI job, just let it skip the p4 tests when this + happens. + (merge f15e00b463 cb/ci-make-p4-optional later to maint). + + * A bit of test framework fixes with a few fixes to issues found by + valgrind. + (merge 7c898554d7 ab/valgrind-fixes later to maint). + + * "git archive --add-file=<path>" picked up the raw permission bits + from the path and propagated to zip output in some cases, without + normalization, which has been corrected (tar output did not have + this issue). + (merge 6a61661967 jc/archive-add-file-normalize-mode later to maint). + + * "make coverage-report" without first running "make coverage" did + not produce any meaningful result, which has been corrected. + (merge 96ddfecc5b ep/coverage-report-wants-test-to-have-run later to maint). + + * The "--current" option of "git show-branch" should have been made + incompatible with the "--reflog" mode, but this was not enforced, + which has been corrected. + (merge 41c64ae0e7 jc/show-branch-g-current later to maint). + + * "git fetch" unnecessarily failed when an unexpected optional + section appeared in the output, which has been corrected. + (merge 7709acf7be jt/fetch-peek-optional-section later to maint). + + * The way "git fetch" without "--update-head-ok" ensures that HEAD in + no worktree points at any ref being updated was too wasteful, which + has been optimized a bit. + (merge f7400da800 os/fetch-check-not-current-branch later to maint). + + * "git fetch --recurse-submodules" from multiple remotes (either from + a remote group, or "--all") used to make one extra "git fetch" in + the submodules, which has been corrected. + (merge 0353c68818 jc/avoid-redundant-submodule-fetch later to maint). + + * With a recent update to refuse access to repositories of other + people by default, "sudo make install" and "sudo git describe" + stopped working, which has been corrected. + (merge 6b11e3d52e cb/path-owner-check-with-sudo-plus later to maint). + + * The tests that ensured merges stop when interfering local changes + are present did not make sure that local changes are preserved; now + they do. + (merge 4b317450ce jc/t6424-failing-merge-preserve-local-changes later to maint). + + * Some real problems noticed by gcc 12 have been fixed, while false + positives have been worked around. + + * Update the version of FreeBSD image used in Cirrus CI. + (merge c58bebd4c6 pb/use-freebsd-12.3-in-cirrus-ci later to maint). + + * The multi-pack-index code did not protect the packfile it is going + to depend on from getting removed while in use, which has been + corrected. + (merge 4090511e40 tb/midx-race-in-pack-objects later to maint). + + * Teach "git repack --geometric" work better with "--keep-pack" and + avoid corrupting the repository when packsize limit is used. + (merge 66731ff921 tb/geom-repack-with-keep-and-max later to maint). + + * The documentation on the interaction between "--add-file" and + "--prefix" options of "git archive" has been improved. + (merge a75910602a rs/document-archive-prefix later to maint). + + * A git subcommand like "git add -p" spawns a separate git process + while relaying its command line arguments. A pathspec with only + negative elements was mistakenly passed with an empty string, which + has been corrected. + (merge b02fdbc80a jc/all-negative-pathspec later to maint). + + * With a more targeted workaround in http.c in another topic, we may + be able to lift this blanket "GCC12 dangling-pointer warning is + broken and unsalvageable" workaround. + (merge 419141e495 cb/buggy-gcc-12-workaround later to maint). + + * A misconfigured 'branch..remote' led to a bug in configuration + parsing. + (merge f1dfbd9ee0 gc/zero-length-branch-config-fix later to maint). + + * "git -c diff.submodule=log range-diff" did not show anything for + submodules that changed in the ranges being compared, and + "git -c diff.submodule=diff range-diff" did not work correctly. + Fix this by including the "--submodule=short" output + unconditionally to be compared. + + * In Git 2.36 we revamped the way how hooks are invoked. One change + that is end-user visible is that the output of a hook is no longer + directly connected to the standard output of "git" that spawns the + hook, which was noticed post release. This is getting corrected. + (merge a082345372 ab/hooks-regression-fix later to maint). + + * Updating the graft information invalidates the list of parents of + in-core commit objects that used to be in the graft file. + + * "git show-ref --heads" (and "--tags") still iterated over all the + refs only to discard refs outside the specified area, which has + been corrected. + (merge c0c9d35e27 tb/show-ref-optim later to maint). + + * Remove redundant copying (with index v3 and older) or possible + over-reading beyond end of mmapped memory (with index v4) has been + corrected. + (merge 6d858341d2 zh/read-cache-copy-name-entry-fix later to maint). + + * Sample watchman interface hook sometimes failed to produce + correctly formatted JSON message, which has been corrected. + (merge 134047b500 sn/fsmonitor-missing-clock later to maint). + + * Use-after-free (with another forget-to-free) fix. + (merge 323822c72b ab/remote-free-fix later to maint). + + * Remove a coccinelle rule that is no longer relevant. + (merge b1299de4a1 jc/cocci-cleanup later to maint). + + * Other code cleanup, docfix, build fix, etc. + (merge e6b2582da3 cm/reftable-0-length-memset later to maint). + (merge 0b75e5bf22 ab/misc-cleanup later to maint). + (merge 52e1ab8a76 ea/rebase-code-simplify later to maint). + (merge 756d15923b sg/safe-directory-tests-and-docs later to maint). + (merge d097a23bfa ds/do-not-call-bug-on-bad-refs later to maint). + (merge c36c27e75c rs/t7812-pcre2-ws-bug-test later to maint). + (merge 1da312742d gf/unused-includes later to maint). + (merge 465b30a92d pb/submodule-recurse-mode-enum later to maint). + (merge 82b28c4ed8 km/t3501-use-test-helpers later to maint). + (merge 72315e431b sa/t1011-use-helpers later to maint). + (merge 95b3002201 cg/vscode-with-gdb later to maint). + (merge fbe5f6b804 tk/p4-utf8-bom later to maint). + (merge 17f273ffba tk/p4-with-explicity-sync later to maint). + (merge 944db25c60 kf/p4-multiple-remotes later to maint). + (merge b014cee8de jc/update-ozlabs-url later to maint). + (merge 4ec5008062 pb/ggg-in-mfc-doc later to maint). + (merge af845a604d tb/receive-pack-code-cleanup later to maint). + (merge 2acf4cf001 js/ci-gcc-12-fixes later to maint). + (merge 05e280c0a6 jc/http-clear-finished-pointer later to maint). + (merge 8c49d704ef fh/transport-push-leakfix later to maint). + (merge 1d232d38bd tl/ls-tree-oid-only later to maint). + (merge db7961e6a6 gc/document-config-worktree-scope later to maint). + (merge ce18a30bb7 fs/ssh-default-key-command-doc later to maint). |
