Git 2.34 Release Notes ====================== Updates since Git 2.33 ---------------------- UI, Workflows & Features * Pathname expansion (like "~username/") learned a way to specify a location relative to Git installation (e.g. its $sharedir which is $(prefix)/share), with "%(prefix)". * Use `ort` instead of `recursive` as the default merge strategy. * The userdiff pattern for "java" language has been updated. * "git rebase" by default skips changes that are equivalent to commits that are already in the history the branch is rebased onto; give messages when this happens to let the users be aware of skipped commits, and also teach them how to tell "rebase" to keep duplicated changes. * The advice message that "git cherry-pick" gives when it asks conflicted replay of a commit to be resolved by the end user has been updated. * After "git clone --recurse-submodules", all submodules are cloned but they are not by default recursed into by other commands. With submodule.stickyRecursiveClone configuration set, submodule.recurse configuration is set to true in a repository created by "clone" with "--recurse-submodules" option. * The logic for auto-correction of misspelt subcommands learned to go interactive when the help.autocorrect configuration variable is set to 'prompt'. Performance, Internal Implementation, Development Support etc. * "git bisect" spawned "git show-branch" only to pretty-print the title of the commit after checking out the next version to be tested; this has been rewritten in C. * "git add" can work better with the sparse index. * Support for ancient versions of cURL library (pre 7.19.4) has been dropped. * A handful of tests that assumed implementation details of files backend for refs have been cleaned up. * trace2 logs learned to show parent process name to see in what context Git was invoked. * Loading of ref tips to prepare for common ancestry negotiation in "git fetch-pack" has been optimized by taking advantage of the commit graph when available. * Remind developers that the userdiff patterns should be kept simple and permissive, assuming that the contents they apply are always syntactically correct. * The current implementation of GIT_TEST_FAIL_PREREQS is broken in that checking for the lack of a prerequisite would not work. Avoid the use of "if ! test_have_prereq X" in a test script. * The revision traversal API has been optimized by taking advantage of the commit-graph, when available, to determine if a commit is reachable from any of the existing refs. * "git fetch --quiet" optimization to avoid useless computation of info that will never be displayed. * Callers from older advice_config[] based API has been updated to use the newer advice_if_enabled() and advice_enabled() API. Fixes since v2.33 ----------------- * Input validation of "git pack-objects --stdin-packs" has been corrected. (merge 561fa03529 ab/pack-stdin-packs-fix later to maint). * Bugfix for common ancestor negotiation recently introduced in "git push" code path. (merge 82823118b9 jt/push-negotiation-fixes later to maint). * "git pull" had various corner cases that were not well thought out around its --rebase backend, e.g. "git pull --ff-only" did not stop but went ahead and rebased when the history on other side is not a descendant of our history. The series tries to fix them up. (merge 6f843a3355 en/pull-conflicting-options later to maint). * "git apply" miscounted the bytes and failed to read to the end of binary hunks. (merge 46d723ce57 jk/apply-binary-hunk-parsing-fix later to maint). * "git range-diff" code clean-up. (merge c4d5907324 jk/range-diff-fixes later to maint). * "git commit --fixup" now works with "--edit" again, after it was broken in v2.32. (merge 8ef6aad664 jk/commit-edit-fixup-fix later to maint). * Use upload-artifacts v1 (instead of v2) for 32-bit linux, as the new version has a blocker bug for that architecture. (merge 3cf9bb36bf cb/ci-use-upload-artifacts-v1 later to maint). * Checking out all the paths from HEAD during the last conflicted step in "git rebase" and continuing would cause the step to be skipped (which is expected), but leaves MERGE_MSG file behind in $GIT_DIR and confuses the next "git commit", which has been corrected. (merge e5ee33e855 pw/rebase-skip-final-fix later to maint). * Various bugs in "git rebase -r" have been fixed. (merge f2563c9ef3 pw/rebase-r-fixes later to maint). * mmap() imitation used to call xmalloc() that dies upon malloc() failure, which has been corrected to just return an error to the caller to be handled. (merge 95b4ff3931 rs/git-mmap-uses-malloc later to maint). * "git diff --relative" segfaulted and/or produced incorrect result when there are unmerged paths. (merge 8174627b3d dd/diff-files-unmerged-fix later to maint). * The delayed checkout code path in "git checkout" etc. were chatty even when --quiet and/or --no-progress options were given. (merge 7a132c628e mt/quiet-with-delayed-checkout later to maint). * "git branch -D " used to refuse to remove a broken branch ref that points at a missing commit, which has been corrected. (merge 597a977489 rs/branch-allow-deleting-dangling later to maint). * Build update for Apple clang. (merge f32c5d3716 cb/makefile-apple-clang later to maint). * The parser for the "--nl" option of "git column" has been corrected. (merge c93ca46cf5 sg/column-nl later to maint). * "git upload-pack" which runs on the other side of "git fetch" forgot to take the ref namespaces into account when handling want-ref requests. (merge 53a66ec37c ka/want-ref-in-namespace later to maint). * The sparse-index support can corrupt the index structure by storing a stale and/or uninitialized data, which has been corrected. (merge d9e9b44d7a jh/sparse-index-resize-fix later to maint). * Buggy tests could damage repositories outside the throw-away test area we created. We now by default export GIT_CEILING_DIRECTORIES to limit the damage from such a stray test. (merge 614c3d8f2e sg/set-ceiling-during-tests later to maint). * Even when running "git send-email" without its own threaded discussion support, a threading related header in one message is carried over to the subsequent message to result in an unwanted threading, which has been corrected. (merge e082113484 mh/send-email-reset-in-reply-to later to maint). * The output from "git fast-export", when its anonymization feature is in use, showed an annotated tag incorrectly. (merge 2f040a9671 tk/fast-export-anonymized-tag-fix later to maint). * Doc update plus improved error reporting. (merge 1e93770888 jk/log-warn-on-bogus-encoding later to maint). * Other code cleanup, docfix, build fix, etc. (merge 1d9c8daef8 ab/bundle-doc later to maint).
