This + possibly may open us to show other kinds of states in the future. + + * "git maintenance", an extended big brother of "git gc", continues + to evolve. + + * "git push --force-with-lease[=<ref>]" can easily be misused to lose + commits unless the user takes good care of their own "git fetch". + A new option "--force-if-includes" attempts to ensure that what is + being force-pushed was created after examining the commit at the + tip of the remote ref that is about to be force-replaced. + + * "git clone" learned clone.defaultremotename configuration variable + to customize what nickname to use to call the remote the repository + was cloned from. + + * "git checkout" learned to use checkout.guess configuration variable + and enable/disable its "--[no-]guess" option accordingly. + + * "git resurrect" script (in contrib/) learned that the object names + may be longer than 40-hex depending on the hash function in use. + + * "git diff A...B" learned "git diff --merge-base A B", which is a + longer short-hand to say the same thing. + + * A sample 'push-to-checkout' hook, that performs the same as + what the built-in default action does, has been added. + + * "git diff" family of commands learned the "-I<regex>" option to + ignore hunks whose changed lines all match the given pattern. + + * The userdiff pattern learned to identify the function definition in + POSIX shells and bash. + + * "git checkout-index" did not consistently signal an error with its + exit status, but now it does. + + * A commit and tag object may have CR at the end of each and + every line (you can create such an object with hash-object or + using --cleanup=verbatim to decline the default clean-up + action), but it would make it impossible to have a blank line + to separate the title from the body of the message. We are now + more lenient and accept a line with lone CR on it as a blank line, + too. + + * Exit codes from "git remote add" etc. were not usable by scripted + callers, but now they are. + + * "git archive" now allows compression level higher than "-9" + when generating tar.gz output. + + * Zsh autocompletion (in contrib/) update. + + * The maximum length of output filenames "git format-patch" creates + has become configurable (used to be capped at 64). + + * "git rev-parse" learned the "--end-of-options" to help scripts to + safely take a parameter that is supposed to be a revision, e.g. + "git rev-parse --verify -q --end-of-options $rev". + + +Performance, Internal Implementation, Development Support etc. + + * Use "git archive" more to produce the release tarball. + + * GitHub Actions automated test improvement to skip tests on a tree + identical to what has already been tested. + + * Test-coverage for running commit-graph task "git maintenance" has + been extended. + + * Our test scripts can be told to run only individual pieces while + skipping others with the "--run=..." option; they were taught to + take a substring of test title, in addition to numbers, to name the + test pieces to run. + + * Adjust tests so that they won't scream when the default initial + branch name is changed to 'main'. + + * Rewriting "git bisect" in C continues. + + * More preliminary tests have been added to document desired outcome + of various "directory rename" situations. + + * Micro clean-up of a couple of test scripts. + + * "git diff" and other commands that share the same machinery to + compare with working tree files have been taught to take advantage + of the fsmonitor data when available. + + * The code to detect premature EOF in the sideband demultiplexer has + been cleaned up. + + * Test scripts are being prepared to transition of the default branch + name to 'main'. + + * "git fetch --depth=<n>" over the stateless RPC / smart HTTP + transport handled EOF from the client poorly at the server end. + + * A specialization of hashmap that uses a string as key has been + introduced. Hopefully it will see wider use over time. + + +Fixes since v2.29 +----------------- + + * In 2.29, "--committer-date-is-author-date" option of "rebase" and + "am" subcommands lost the e-mail address by mistake, which has been + corrected. + (merge 5f35edd9d7 jk/committer-date-is-author-date-fix later to maint). + + * "git checkout -p A...B [-- <path>]" did not work, even though the + same command without "-p" correctly used the merge-base between + commits A and B. + (merge 35166b1fb5 dl/checkout-p-merge-base later to maint). + + * The side-band status report can be sent at the same time as the + primary payload multiplexed, but the demultiplexer on the receiving + end incorrectly split a single status report into two, which has + been corrected. + (merge 712b0377db js/avoid-split-sideband-message later to maint). + + * "git fast-import" wasted a lot of memory when many marks were in use. + (merge 3f018ec716 jk/fast-import-marks-alloc-fix later to maint). + + * A test helper "test_cmp A B" was taught to diagnose missing files A + or B as a bug in test, but some tests legitimately wanted to notice + a failure to even create file B as an error, in addition to leaving + the expected result in it, and were misdiagnosed as a bug. This + has been corrected. + (merge 262d5ad5a5 es/test-cmp-typocatcher later to maint). + + * When "git commit-graph" detects the same commit recorded more than + once while it is merging the layers, it used to die. The code now + ignores all but one of them and continues. + (merge 85102ac71b ds/commit-graph-merging-fix later to maint). + + * The meaning of a Signed-off-by trailer can vary from project to + project; this and also what it means to this project has been + clarified in the documentation. + (merge 3abd4a67d9 bk/sob-dco later to maint). + + * "git credential' didn't honor the core.askPass configuration + variable (among other things), which has been corrected. + (merge 567ad2c0f9 tk/credential-config later to maint). + + * Dev support to catch a tentative definition of a variable in our C + code as an error. + (merge 5539183622 jk/no-common later to maint). + + * "git rebase --rebase-merges" did not correctly pass --gpg-sign + command line option to underlying "git merge" when replaying a merge + using non-default merge strategy or when replaying an octopus merge + (because replaying a two-head merge with the default strategy was + done in a separate codepath, the problem did not trigger for most + users), which has been corrected. + (merge 43ad4f2eca sc/sequencer-gpg-octopus later to maint). + + * "git apply -R" did not handle patches that touch the same path + twice correctly, which has been corrected. This is most relevant + in a patch that changes a path from a regular file to a symbolic + link (and vice versa). + (merge b0f266de11 jt/apply-reverse-twice later to maint). + + * A recent oid->hash conversion missed one spot, breaking "git svn". + (merge 03bb366de4 bc/svn-hash-oid-fix later to maint). + + * The documentation on the "--abbrev=<n>" option did not say the + output may be longer than "<n>" hexdigits, which has been + clarified. + (merge cda34e0d0c jc/abbrev-doc later to maint). + + * "git p4" now honors init.defaultBranch configuration. + (merge 1b09d1917f js/p4-default-branch later to maint). + + * Recently the format of an internal state file "rebase -i" uses has + been tightened up for consistency, which would hurt those who start + "rebase -i" with old git and then continue with new git. Loosen + the reader side a bit (which we may want to tighten again in a year + or so). + (merge c779386182 jc/sequencer-stopped-sha-simplify later to maint). + + * The code to see if "git stash drop" can safely remove refs/stash + has been made more carerful. + (merge 4f44c5659b rs/empty-reflog-check-fix later to maint). + + * "git log -L<range>:<path>" is documented to take no pathspec, but + this was not enforced by the command line option parser, which has + been corrected. + (merge 39664cb0ac jc/line-log-takes-no-pathspec later to maint). + + * "git format-patch --output=there" did not work as expected and + instead crashed. The option is now supported. + (merge dc1672dd10 jk/format-patch-output later to maint). + + * Define ARM64 compiled with MSVC to be little-endian. + (merge 0c038fc65a dg/bswap-msvc later to maint). + + * "git rebase -i" did not store ORIG_HEAD correctly. + (merge 8843302307 pw/rebase-i-orig-head later to maint). + + * "git blame -L :funcname -- path" did not work well for a path for + which a userdiff driver is defined. + + * "make DEVELOPER=1 sparse" used to run sparse and let it emit + warnings; now such warnings will cause an error. + (merge 521dc56270 jc/sparse-error-for-developer-build later to maint). + + * "git blame --ignore-revs-file=<file>" learned to ignore a + non-existent object name in the input, instead of complaining. + (merge c714d05875 jc/blame-ignore-fix later to maint). + + * Running "git diff" while allowing external diff in a state with + unmerged paths used to segfault, which has been corrected. + (merge d66851806f jk/diff-release-filespec-fix later to maint). + + * Build configuration cleanup. + (merge b990f02fd8 ab/config-mak-uname-simplify later to maint). + + * Fix regression introduced when nvimdiff support in mergetool was added. + (merge 12026f46e7 pd/mergetool-nvimdiff later to maint). + + * Other code cleanup, docfix, build fix, etc. + (merge 3e0a5dc9af cc/doc-filter-branch-typofix later to maint). + (merge 32c83afc2c cw/ci-ghwf-check-ws-errors later to maint). + (merge 5eb2ed691b rs/tighten-callers-of-deref-tag later to maint). + (merge 6db29ab213 jk/fast-import-marks-cleanup later to maint). + (merge e5cf6d3df4 nk/dir-c-comment-update later to maint). + (merge 5710dcce74 jk/report-fn-typedef later to maint). + (merge 9a82db1056 en/sequencer-rollback-lock-cleanup later to maint). + (merge 4e1bee9a99 js/t7006-cleanup later to maint). + (merge f5bcde6c58 es/tutorial-mention-asciidoc-early later to maint). + (merge 714d491af0 so/format-patch-doc-on-default-diff-format later to maint). + (merge 0795df4b9b rs/clear-commit-marks-in-repo later to maint). + (merge 9542d56379 sd/prompt-local-variable later to maint). + (merge 06d43fad18 rs/pack-write-hashwrite-simplify later to maint). + (merge b7e20b4373 mc/typofix later to maint). + (merge f6bcd9a8a4 js/test-whitespace-fixes later to maint). + (merge 53b67a801b js/test-file-size later to maint). |
