The documentation and + code have been taught to make more clear recommendations when the + users see failures. + + * Management of sparsely checked-out working tree has gained a + dedicated "sparse-checkout" command. + + * Miscellaneous small UX improvements on "git-p4". + + * "git sparse-checkout list" subcommand learned to give its output in + a more concise form when the "cone" mode is in effect. + + +Performance, Internal Implementation, Development Support etc. + + * Debugging support for lazy cloning has been a bit improved. + + * Move the definition of a set of bitmask constants from 0ctal + literal to (1U<<count) notation. + + * Test updates to prepare for SHA-2 transition continues. + + * Crufty code and logic accumulated over time around the object + parsing and low-level object access used in "git fsck" have been + cleaned up. + + * The implementation of "git log --graph" got refactored and then its + output got simplified. + + * Follow recent push to move API docs from Documentation/ to header + files and update config.h + + * "git bundle" has been taught to use the parse options API. "git + bundle verify" learned "--quiet" and "git bundle create" learned + options to control the progress output. + + * Handling of commit objects that use non UTF-8 encoding during + "rebase -i" has been improved. + + * The beginning of rewriting "git add -i" in C. + + * A label used in the todo list that are generated by "git rebase + --rebase-merges" is used as a part of a refname; the logic to come + up with the label has been tightened to avoid names that cannot be + used as such. + + * The logic to avoid duplicate label names generated by "git rebase + --rebase-merges" forgot that the machinery itself uses "onto" as a + label name, which must be avoided by auto-generated labels, which + has been corrected. + + * We have had compatibility fallback macro definitions for "PRIuMAX", + "PRIu32", etc. but did not for "PRIdMAX", while the code used the + last one apparently without any hiccup reported recently. The + fallback macro definitions for these <inttypes.h> macros that must + appear in C99 systems have been removed. + + * Recently we have declared that GIT_TEST_* variables take the + usual boolean values (it used to be that some used "non-empty + means true" and taking GIT_TEST_VAR=YesPlease as true); make + sure we notice and fail when non-bool strings are given to + these variables. + + * Users of oneway_merge() (like "reset --hard") learned to take + advantage of fsmonitor to avoid unnecessary lstat(2) calls. + + * Performance tweak on "git push" into a repository with many refs + that point at objects we have never heard of. + + * PerfTest fix to avoid stale result mixed up with the latest round + of test results. + + * Hide lower-level verify_signed-buffer() API as a pure helper to + implement the public check_signature() function, in order to + encourage new callers to use the correct and more strict + validation. + + * Unnecessary reading of state variables back from the disk during + sequencer operation has been reduced. + + * The code has been made to avoid gmtime() and localtime() and prefer + their reentrant counterparts. + + * In a repository with many packfiles, the cost of the procedure that + avoids registering the same packfile twice was unnecessarily high + by using an inefficient search algorithm, which has been corrected. + + * Redo "git name-rev" to avoid recursive calls. + + * FreeBSD CI support via Cirrus-CI has been added. + + +Fixes since v2.24 +----------------- + + * "rebase -i" ceased to run post-commit hook by mistake in an earlier + update, which has been corrected. + + * "git notes copy $original" ought to copy the notes attached to the + original object to HEAD, but a mistaken tightening to command line + parameter validation made earlier disabled that feature by mistake. + + * When all files from some subdirectory were renamed to the root + directory, the directory rename heuristics would fail to detect that + as a rename/merge of the subdirectory to the root directory, which has + been corrected. + + * Code clean-up and a bugfix in the logic used to tell worktree local + and repository global refs apart. + (merge f45f88b2e4 sg/dir-trie-fixes later to maint). + + * "git stash save" in a working tree that is sparsely checked out + mistakenly removed paths that are outside the area of interest. + (merge 4a58c3d7f7 js/update-index-ignore-removal-for-skip-worktree later to maint). + + * "git rev-parse --git-path HEAD.lock" did not give the right path + when run in a secondary worktree. + (merge 76a53d640f js/git-path-head-dot-lock-fix later to maint). + + * "git merge --no-commit" needs "--no-ff" if you do not want to move + HEAD, which has been corrected in the manual page for "git bisect". + (merge 8dd327b246 ma/bisect-doc-sample-update later to maint). + + * "git worktree add" internally calls "reset --hard" that should not + descend into submodules, even when submodule.recurse configuration + is set, but it was affected. This has been corrected. + (merge 4782cf2ab6 pb/no-recursive-reset-hard-in-worktree-add later to maint). + + * Messages from die() etc. can be mixed up from multiple processes + without even line buffering on Windows, which has been worked + around. + (merge 116d1fa6c6 js/vreportf-wo-buffering later to maint). + + * HTTP transport had possible allocator/deallocator mismatch, which + has been corrected. + + * The watchman integration for fsmonitor was racy, which has been + corrected to be more conservative. + (merge dd0b61f577 kw/fsmonitor-watchman-fix later to maint). + + * Fetching from multiple remotes into the same repository in parallel + had a bad interaction with the recent change to (optionally) update + the commit-graph after a fetch job finishes, as these parallel + fetches compete with each other. Which has been corrected. + + * Recent update to "git stash pop" made the command empty the index + when run with the "--quiet" option, which has been corrected. + + * "git fetch" codepath had a big "do not lazily fetch missing objects + when I ask if something exists" switch. This has been corrected by + marking the "does this thing exist?" calls with "if not please do not + lazily fetch it" flag. + + * Test update to avoid wasted cycles. + (merge e0316695ec sg/skip-skipped-prereq later to maint). + + * Error handling after "git push" finishes sending the packdata and + waits for the response to the remote side has been improved. + (merge ad7a403268 jk/send-pack-remote-failure later to maint). + + * Some codepaths in "gitweb" that forgot to escape URLs generated + based on end-user input have been corrected. + (merge a376e37b2c jk/gitweb-anti-xss later to maint). + + * CI jobs for macOS has been made less chatty when updating perforce + package used during testing. + (merge 0dbc4a0edf jc/azure-ci-osx-fix-fix later to maint). + + * "git unpack-objects" used to show progress based only on the number + of received and unpacked objects, which stalled when it has to + handle an unusually large object. It now shows the throughput as + well. + (merge bae60ba7e9 sg/unpack-progress-throughput later to maint). + + * The sequencer machinery compared the HEAD and the state it is + attempting to commit to decide if the result would be a no-op + commit, even when amending a commit, which was incorrect, and + has been corrected. + + * The code to parse GPG output used to assume incorrectly that the + finterprint for the primary key would always be present for a valid + signature, which has been corrected. + (merge 67a6ea6300 hi/gpg-optional-pkfp-fix later to maint). + + * "git submodule status" and "git submodule status --cached" show + different things, but the documentation did not cover them + correctly, which has been corrected. + (merge 8d483c8408 mg/doc-submodule-status-cached later to maint). + + * "git reset --patch $object" without any pathspec should allow a + tree object to be given, but incorrectly required a committish, + which has been corrected. + + * "git submodule status" that is run from a subdirectory of the + superproject did not work well, which has been corrected. + (merge 1f3aea22c7 mg/submodule-status-from-a-subdirectory later to maint). + + * The revision walking machinery uses resources like per-object flag + bits that need to be reset before a new iteration of walking + begins, but the resources related to topological walk were not + cleared correctly, which has been corrected. + (merge 0aa0c2b2ec mh/clear-topo-walk-upon-reset later to maint). + + * TravisCI update. + (merge 176441bfb5 sg/osx-force-gcc-9 later to maint). + + * While running "revert" or "cherry-pick --edit" for multiple + commits, a recent regression incorrectly detected "nothing to + commit, working tree clean", instead of replaying the commits, + which has been corrected. + (merge befd4f6a81 sg/assume-no-todo-update-in-cherry-pick later to maint). + + * Work around a issue where a FD that is left open when spawning a + child process and is kept open in the child can interfere with the + operation in the parent process on Windows. + + * One kind of progress messages were always given during commit-graph + generation, instead of following the "if it takes more than two + seconds, show progress" pattern, which has been corrected. + + * "git rebase" did not work well when format.useAutoBase + configuration variable is set, which has been corrected. + + * The "diff" machinery learned not to lose added/removed blank lines + in the context when --ignore-blank-lines and --function-context are + used at the same time. + (merge 0bb313a552 rs/xdiff-ignore-ws-w-func-context later to maint). + + * The test on "fast-import" used to get stuck when "fast-import" died + in the middle. + (merge 0d9b0d7885 sg/t9300-robustify later to maint). + + * "git format-patch" can take a set of configured format.notes values + to specify which notes refs to use in the log message part of the + output. The behaviour of this was not consistent with multiple + --notes command line options, which has been corrected. + (merge e0f9095aaa dl/format-patch-notes-config-fixup later to maint). + + * "git p4" used to ignore lfs.storage configuration variable, which + has been corrected. + (merge ea94b16fb8 rb/p4-lfs later to maint). + + * Assorted fixes to the directory traversal API. + (merge 6836d2fe06 en/fill-directory-fixes later to maint). + + * Forbid pathnames that the platform's filesystem cannot represent on + MinGW. + (merge 4dc42c6c18 js/mingw-reserved-filenames later to maint). + + * "git rebase --signoff" stopped working when the command was written + in C, which has been corrected. + (merge 4fe7e43c53 en/rebase-signoff-fix later to maint). + + * An earlier update to Git for Windows declared that a tree object is + invalid if it has a path component with backslash in it, which was + overly strict, which has been corrected. The only protection the + Windows users need is to prevent such path (or any path that their + filesystem cannot check out) from entering the index. + (merge 224c7d70fa js/mingw-loosen-overstrict-tree-entry-checks later to maint). + + * The code to write split commit-graph file(s) upon fetching computed + bogus value for the parameter used in splitting the resulting + files, which has been corrected. + (merge 63020f175f ds/commit-graph-set-size-mult later to maint). + + * Other code cleanup, docfix, build fix, etc. + (merge 80736d7c5e jc/am-show-current-patch-docfix later to maint). + (merge 8b656572ca sg/commit-graph-usage-fix later to maint). + (merge 6c02042139 mr/clone-dir-exists-to-path-exists later to maint). + (merge 44ae131e38 sg/blame-indent-heuristics-is-now-the-default later to maint). + (merge 0115e5d929 dl/doc-diff-no-index-implies-exit-code later to maint). + (merge 270de6acbe en/t6024-style later to maint). + (merge 14c4776d75 ns/test-desc-typofix later to maint). + (merge 68d40f30c4 dj/typofix-merge-strat later to maint). + (merge f66e0401ab jk/optim-in-pack-idx-conversion later to maint). + (merge 169bed7421 rs/parse-options-dup-null-fix later to maint). + (merge 51bd6be32d rs/use-copy-array-in-mingw-shell-command-preparation later to maint). + (merge b018719927 ma/t7004 later to maint). + (merge 932757b0cc ar/install-doc-update-cmds-needing-the-shell later to maint). + (merge 46efd28be1 ep/guard-kset-tar-headers later to maint). + (merge 9e5afdf997 ec/fetch-mark-common-refs-trace2 later to maint). + (merge f0e58b3fe8 pb/submodule-update-fetches later to maint). + (merge 2a02262078 dl/t5520-cleanup later to maint). + (merge a4fb016ba1 js/pkt-line-h-typofix later to maint). + (merge 54a7a64613 rs/simplify-prepare-cmd later to maint). + (merge 3eae30e464 jk/lore-is-the-archive later to maint). + (merge 14b7664df8 dl/lore-is-the-archive later to maint). + (merge 0e40a73a4c po/bundle-doc-clonable later to maint). + (merge e714b898c6 as/t7812-missing-redirects-fix later to maint). + (merge 528d9e6d01 jk/perf-wo-git-dot-pm later to maint). + (merge fc42f20e24 sg/test-squelch-noise-in-commit-bulk later to maint). + (merge c64368e3a2 bc/t9001-zsh-in-posix-emulation-mode later to maint). + (merge 11de8dd7ef dr/branch-usage-casefix later to maint). + (merge e05e8cf074 rs/archive-zip-code-cleanup later to maint). + (merge 147ee35558 rs/commit-export-env-simplify later to maint). + (merge 4507ecc771 rs/patch-id-use-oid-to-hex later to maint). + (merge 51a0a4ed95 mr/bisect-use-after-free later to maint). + (merge cc2bd5c45d pb/submodule-doc-xref later to maint). + (merge df5be01669 ja/doc-markup-cleanup later to maint). + (merge 7c5cea7242 mr/bisect-save-pointer-to-const-string later to maint). + (merge 20a67e8ce9 js/use-test-tool-on-path later to maint). + (merge 4e61b2214d ew/packfile-syscall-optim later to maint). + (merge ace0f86c7f pb/clarify-line-log-doc later to maint). + (merge 763a59e71c en/merge-recursive-oid-eq-simplify later to maint). + (merge 4e2c4c0d4f do/gitweb-typofix-in-comments later to maint). + (merge 421c0ffb02 jb/doc-multi-pack-idx-fix later to maint). + (merge f8740c586b pm/am-in-body-header-doc-update later to maint). + (merge 5814d44d9b tm/doc-submodule-absorb-fix later to maint). |
