See the + instruction at the beginning of git-compat-util.h if this happens + to you. + + +UI, Workflows & Features + + * "git status --porcelain=v2" now show the number of stash entries + with --show-stash like the normal output does. + + * "git stash" learned the "--staged" option to stash away what has + been added to the index (and nothing else). + + * "git var GIT_DEFAULT_BRANCH" is a way to see what name is used for + the newly created branch if "git init" is run. + + * Various operating modes of "git reset" have been made to work + better with the sparse index. + + * "git submodule deinit" for a submodule whose .git metadata + directory is embedded in its working tree refused to work, until + the submodule gets converted to use the "absorbed" form where the + metadata directory is stored in superproject, and a gitfile at the + top-level of the working tree of the submodule points at it. The + command is taught to convert such submodules to the absorbed form + as needed. + + * The completion script (in contrib/) learns that the "--date" + option of commands from the "git log" family takes "human" and + "auto" as valid values. + + * "Zealous diff3" style of merge conflict presentation has been added. + + * The "git log --format=%(describe)" placeholder has been extended to + allow passing selected command-line options to the underlying "git + describe" command. + + * "default" and "reset" have been added to our color palette. + + * The cryptographic signing using ssh keys can specify literal keys + for keytypes whose name do not begin with the "ssh-" prefix by + using the "key::" prefix mechanism (e.g. "key::ecdsa-sha2-nistp256"). + + * "git fetch" without the "--update-head-ok" option ought to protect + a checked out branch from getting updated, to prevent the working + tree that checks it out to go out of sync. The code was written + before the use of "git worktree" got widespread, and only checked + the branch that was checked out in the current worktree, which has + been updated. + + * "git name-rev" has been tweaked to give output that is shorter and + easier to understand. + + * "git apply" has been taught to ignore a message without a patch + with the "--allow-empty" option. It also learned to honor the + "--quiet" option given from the command line. + + * The "init" and "set" subcommands in "git sparse-checkout" have been + unified for a better user experience and performance. + + * Many git commands that deal with working tree files try to remove a + directory that becomes empty (i.e. "git switch" from a branch that + has the directory to another branch that does not would attempt + remove all files in the directory and the directory itself). This + drops users into an unfamiliar situation if the command was run in + a subdirectory that becomes subject to removal due to the command. + The commands have been taught to keep an empty directory if it is + the directory they were started in to avoid surprising users. + + * "git am" learns "--empty=(stop|drop|keep)" option to tweak what is + done to a piece of e-mail without a patch in it. + + * The default merge message prepared by "git merge" records the name + of the current branch; the name can be overridden with a new option + to allow users to pretend a merge is made on a different branch. + + * The way "git p4" shows file sizes in its output has been updated to + use human-readable units. + + * "git -c branch.autosetupmerge=inherit branch new old" makes "new" + to have the same upstream as the "old" branch, instead of marking + "old" itself as its upstream. + + +Performance, Internal Implementation, Development Support etc. + + * The use of errno as a means to carry the nature of error in the ref + API implementation has been reworked and reduced. + + * Teach and encourage first-time contributors to this project to + state the base commit when they submit their topic. + + * The command line completion for "git send-email" options have been + tweaked to make it easier to keep it in sync with the command itself. + + * Ensure that the sparseness of the in-core index matches the + index.sparse configuration specified by the repository immediately + after the on-disk index file is read. + + * Code clean-up to eventually allow information on remotes defined + for an arbitrary repository to be read. + + * Build optimization. + + * Tighten code for testing pack-bitmap. + + * Weather balloon to break people with compilers that do not support + C99. + + * The "reftable" backend for the refs API, without integrating into + the refs subsystem, has been added. + + * More tests are marked as leak-free. + + * The test framework learns to list unsatisfied test prerequisites, + and optionally error out when prerequisites that are expected to be + satisfied are not. + + * The default setting for trace2 event nesting was too low to cause + test failures, which is worked around by bumping it up in the test + framework. + + * Drop support for TravisCI and update test workflows at GitHub. + + * Many tests that used to need GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME + mechanism to force "git" to use 'master' as the default name for + the initial branch no longer need it; the use of the mechanism from + them have been removed. + + * Allow running our tests while disabling fsync. + + * Document the parameters given to the reflog entry iterator callback + functions. + (merge e6e94f34b2 jc/reflog-iterator-callback-doc later to maint). + + * The test helper for refs subsystem learned to write bogus and/or + nonexistent object name to refs to simulate error situations we + want to test Git in. + + * "diff --histogram" optimization. + + * Weather balloon to find compilers that do not grok variable + declaration in the for() loop. + + * diff and blame commands have been taught to work better with sparse + index. + + * The chainlint test script linter in the test suite has been updated. + + * The DEVELOPER=yes build uses -std=gnu99 now. + + * "git format-patch" uses a single rev_info instance and then exits. + Mark the structure with UNLEAK() macro to squelch leak sanitizer. + + * New interface into the tmp-objdir API to help in-core use of the + quarantine feature. + + * Broken &&-chains in the test scripts have been corrected. + + * The RCS keyword substitution in "git p4" used to be done assuming + that the contents are UTF-8 text, which can trigger decoding + errors. We now treat the contents as a bytestring for robustness + and correctness. + + * The conditions to choose different definitions of the FLEX_ARRAY + macro for vendor compilers has been simplified to make it easier to + maintain. + + * Correctness and performance update to "diff --color-moved" feature. + + * "git upload-pack" (the other side of "git fetch") used a 8kB buffer + but most of its payload came on 64kB "packets". The buffer size + has been enlarged so that such a packet fits. + + * "git fetch" and "git pull" are now declared sparse-index clean. + Also "git ls-files" learns the "--sparse" option to help debugging. + + * Similar message templates have been consolidated so that + translators need to work on fewer number of messages. + + +Fixes since v2.34 +----------------- + + * "git grep" looking in a blob that has non-UTF8 payload was + completely broken when linked with certain versions of PCREv2 + library in the latest release. + + * Other code cleanup, docfix, build fix, etc. + + * "git pull" with any strategy when the other side is behind us + should succeed as it is a no-op, but doesn't. + + * An earlier change in 2.34.0 caused JGit application (that abused + GIT_EDITOR mechanism when invoking "git config") to get stuck with + a SIGTTOU signal; it has been reverted. + + * An earlier change that broke .gitignore matching has been reverted. + + * Things like "git -c branch.sort=bogus branch new HEAD", i.e. the + operation modes of the "git branch" command that do not need the + sort key information, no longer errors out by seeing a bogus sort + key. + (merge 98e7ab6d42 jc/fix-ref-sorting-parse later to maint). + + * The compatibility implementation for unsetenv(3) were written to + mimic ancient, non-POSIX, variant seen in an old glibc; it has been + changed to return an integer to match the more modern era. + (merge a38989bd5b jc/unsetenv-returns-an-int later to maint). + + * The clean/smudge conversion code path has been prepared to better + work on platforms where ulong is narrower than size_t. + (merge 596b5e77c9 mc/clean-smudge-with-llp64 later to maint). + + * Redact the path part of packfile URI that appears in the trace output. + (merge 0ba558ffb1 if/redact-packfile-uri later to maint). + + * CI has been taught to catch some Unicode directional formatting + sequence that can be used in certain mischief. + (merge 0e7696c64d js/ci-no-directional-formatting later to maint). + + * The "--date=format:<strftime>" gained a workaround for the lack of + system support for a non-local timezone to handle "%s" placeholder. + (merge 9b591b9403 jk/strbuf-addftime-seconds-since-epoch later to maint). + + * The "merge" subcommand of "git jump" (in contrib/) silently ignored + pathspec and other parameters. + (merge 67ba13e5a4 jk/jump-merge-with-pathspec later to maint). + + * The code to decode the length of packed object size has been + corrected. + (merge 34de5b8eac jt/pack-header-lshift-overflow later to maint). + + * The advice message given by "git pull" when the user hasn't made a + choice between merge and rebase still said that the merge is the + default, which no longer is the case. This has been corrected. + (merge 71076d0edd ah/advice-pull-has-no-preference-between-rebase-and-merge later to maint). + + * "git fetch", when received a bad packfile, can fail with SIGPIPE. + This wasn't wrong per-se, but we now detect the situation and fail + in a more predictable way. + (merge 2a4aed42ec jk/fetch-pack-avoid-sigpipe-to-index-pack later to maint). + + * The function to cull a child process and determine the exit status + had two separate code paths for normal callers and callers in a + signal handler, and the latter did not yield correct value when the + child has caught a signal. The handling of the exit status has + been unified for these two code paths. An existing test with + flakiness has also been corrected. + (merge 5263e22cba jk/t7006-sigpipe-tests-fix later to maint). + + * When a non-existent program is given as the pager, we tried to + reuse an uninitialized child_process structure and crashed, which + has been fixed. + (merge f917f57f40 em/missing-pager later to maint). + + * The single-key-input mode in "git add -p" had some code to handle + keys that generate a sequence of input via ReadKey(), which did not + handle end-of-file correctly, which has been fixed. + (merge fc8a8126df cb/add-p-single-key-fix later to maint). + + * "git rebase -x" added an unnecessary 'exec' instructions before + 'noop', which has been corrected. + (merge cc9dcdee61 en/rebase-x-fix later to maint). + + * When the "git push" command is killed while the receiving end is + trying to report what happened to the ref update proposals, the + latter used to die, due to SIGPIPE. The code now ignores SIGPIPE + to increase our chances to run the post-receive hook after it + happens. + (merge d34182b9e3 rj/receive-pack-avoid-sigpipe-during-status-reporting later to maint). + + * "git worktree add" showed "Preparing worktree" message to the + standard output stream, but when it failed, the message from die() + went to the standard error stream. Depending on the order the + stdio streams are flushed at the program end, this resulted in + confusing output. It has been corrected by sending all the chatty + messages to the standard error stream. + (merge b50252484f es/worktree-chatty-to-stderr later to maint). + + * Coding guideline document has been updated to clarify what goes to + standard error in our system. + (merge e258eb4800 es/doc-stdout-vs-stderr later to maint). + + * The sparse-index/sparse-checkout feature had a bug in its use of + the matching code to determine which path is in or outside the + sparse checkout patterns. + (merge 8c5de0d265 ds/sparse-deep-pattern-checkout-fix later to maint). + + * "git rebase -x" by mistake started exporting the GIT_DIR and + GIT_WORK_TREE environment variables when the command was rewritten + in C, which has been corrected. + (merge 434e0636db en/rebase-x-wo-git-dir-env later to maint). + + * When "git log" implicitly enabled the "decoration" processing + without being explicitly asked with "--decorate" option, it failed + to read and honor the settings given by the "--decorate-refs" + option. + + * "git fetch --set-upstream" did not check if there is a current + branch, leading to a segfault when it is run on a detached HEAD, + which has been corrected. + (merge 17baeaf82d ab/fetch-set-upstream-while-detached later to maint). + + * Among some code paths that ask an yes/no question, only one place + gave a prompt that looked different from the others, which has been + updated to match what the others create. + (merge 0fc8ed154c km/help-prompt-fix later to maint). + + * "git log --invert-grep --author=<name>" used to exclude commits + written by the given author, but now "--invert-grep" only affects + the matches made by the "--grep=<pattern>" option. + (merge 794c000267 rs/log-invert-grep-with-headers later to maint). + + * "git grep --perl-regexp" failed to match UTF-8 characters with + wildcard when the pattern consists only of ASCII letters, which has + been corrected. + (merge 32e3e8bc55 rs/pcre2-utf later to maint). + + * Certain sparse-checkout patterns that are valid in non-cone mode + led to segfault in cone mode, which has been corrected. + + * Use of certain "git rev-list" options with "git fast-export" + created nonsense results (the worst two of which being "--reverse" + and "--invert-grep --grep=<foo>"). The use of "--first-parent" is + made to behave a bit more sensible than before. + (merge 726a228dfb ws/fast-export-with-revision-options later to maint). + + * Perf tests were run with end-user's shell, but it has been + corrected to use the shell specified by $TEST_SHELL_PATH. + (merge 9ccab75608 ja/perf-use-specified-shell later to maint). + + * Fix dependency rules to generate hook-list.h header file. + (merge d3fd1a6667 ab/makefile-hook-list-dependency-fix later to maint). + + * "git stash" by default triggers its "push" action, but its + implementation also made "git stash -h" to show short help only for + "git stash push", which has been corrected. + (merge ca7990cea5 ab/do-not-limit-stash-help-to-push later to maint). + + * "git apply --3way" bypasses the attempt to do a three-way + application in more cases to address the regression caused by the + recent change to use direct application as a fallback. + (merge 34d607032c jz/apply-3-corner-cases later to maint). + + * Fix performance-releated bug in "git subtree" (in contrib/). + (merge 3ce8888fb4 jl/subtree-check-parents-argument-passing-fix later to maint). + + * Extend the guidance to choose the base commit to build your work + on, and hint/nudge contributors to read others' changes. + (merge fdfae830f8 jc/doc-submitting-patches-choice-of-base later to maint). + + * A corner case bug in the ort merge strategy has been corrected. + (merge d30126c20d en/merge-ort-renorm-with-rename-delete-conflict-fix later to maint). + + * "git stash apply" forgot to attempt restoring untracked files when + it failed to restore changes to tracked ones. + (merge 71cade5a0b en/stash-df-fix later to maint). + + * Calling dynamically loaded functions on Windows has been corrected. + (merge 4a9b204920 ma/windows-dynload-fix later to maint). + + * Some lockfile code called free() in signal-death code path, which + has been corrected. + (merge 58d4d7f1c5 ps/lockfile-cleanup-fix later to maint). + + * Other code cleanup, docfix, build fix, etc. + (merge 74db416c9c cw/protocol-v2-doc-fix later to maint). + (merge f9b2b6684d ja/doc-cleanup later to maint). + (merge 7d1b866778 jc/fix-first-object-walk later to maint). + (merge 538ac74604 js/trace2-avoid-recursive-errors later to maint). + (merge 152923b132 jk/t5319-midx-corruption-test-deflake later to maint). + (merge 9081a421a6 ab/checkout-branch-info-leakfix later to maint). + (merge 42c456ff81 rs/mergesort later to maint). + (merge ad506e6780 tl/midx-docfix later to maint). + (merge bf5b83fd8a hk/ci-checkwhitespace-commentfix later to maint). + (merge 49f1eb3b34 jk/refs-g11-workaround later to maint). + (merge 7d3fc7df70 jt/midx-doc-fix later to maint). + (merge 7b089120d9 hn/create-reflog-simplify later to maint). + (merge 9e12400da8 cb/mingw-gmtime-r later to maint). + (merge 0bf0de6cc7 tb/pack-revindex-on-disk-cleanup later to maint). + (merge 2c68f577fc ew/cbtree-remove-unused-and-broken-cb-unlink later to maint). + (merge eafd6e7e55 ab/die-with-bug later to maint). + (merge 91028f7659 jc/grep-patterntype-default-doc later to maint). + (merge 47ca93d071 ds/repack-fixlets later to maint). + (merge e6a9bc0c60 rs/t4202-invert-grep-test-fix later to maint). + (merge deb5407a42 gh/gpg-doc-markup-fix later to maint). + (merge 999bba3e0b rs/daemon-plug-leak later to maint). + (merge 786eb1ba39 js/l10n-mention-ngettext-early-in-readme later to maint). + (merge 2f12b31b74 ab/makefile-msgfmt-wo-stats later to maint). + (merge 0517f591ca fs/gpg-unknown-key-test-fix later to maint). + (merge 97d6fb5a1f ma/header-dup-cleanup later to maint). diff --git a/Documentation/RelNotes/2.35.1.txt b/Documentation/RelNotes/2.35.1.txt new file mode 100644 index 0000000000..726ba250ef --- /dev/null +++ b/Documentation/RelNotes/2.35.1.txt @@ -0,0 +1,6 @@ +Git v2.35.1 Release Notes +========================= + +Git 2.35 shipped with a regression that broke use of "rebase" and +"stash" in a secondary worktree.
