2.33.1

Git 2.33.1 Release Notes ========================

This primarily is to backport various fixes accumulated during the development towards Git 2.34, the next feature release.

Fixes since v2.33 -----------------

• The unicode character width table (used for output alignment) has been updated.

• Input validation of "git pack-objects --stdin-packs" has been corrected.

• Bugfix for common ancestor negotiation recently introduced in "git push" codepath.

• "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.

• "git apply" miscounted the bytes and failed to read to the end of binary hunks.

• "git range-diff" code clean-up.

• "git commit --fixup" now works with "--edit" again, after it was broken in v2.32.

• Use upload-artifacts v1 (instead of v2) for 32-bit linux, as the new version has a blocker bug for that architecture.

• 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.

• Various bugs in "git rebase -r" have been fixed.

• 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.

• "git diff --relative" segfaulted and/or produced incorrect result when there are unmerged paths.

• The delayed checkout code path in "git checkout" etc. were chatty even when --quiet and/or --no-progress options were given.

• "git branch -D <branch>" used to refuse to remove a broken branch ref that points at a missing commit, which has been corrected.

• Build update for Apple clang.

• The parser for the "--nl" option of "git column" has been corrected.

• "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.

• The sparse-index support can corrupt the index structure by storing a stale and/or uninitialized data, which has been corrected.

• 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.

• 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.

• The output from "git fast-export", when its anonymization feature is in use, showed an annotated tag incorrectly.

• Recent "diff -m" changes broke "gitk", which has been corrected.

• "git maintenance" scheduler fix for macOS.

• A pathname in an advice message has been made cut-and-paste ready.

• The "git apply -3" code path learned not to bother the lower level merge machinery when the three-way merge can be trivially resolved without the content level merge.

• The code that optionally creates the *.rev reverse index file has been optimized to avoid needless computation when it is not writing the file out.

• "git range-diff -I… <range> <range>" segfaulted, which has been corrected.

• The order in which various files that make up a single (conceptual) packfile has been reevaluated and straightened up. This matters in correctness, as an incomplete set of files must not be shown to a running Git.

• The "mode" word is useless in a call to open(2) that does not create a new file. Such a call in the files backend of the ref subsystem has been cleaned up.

• "git update-ref --stdin" failed to flush its output as needed, which potentially led the conversation to a deadlock.

• When "git am --abort" fails to abort correctly, it still exited with exit status of 0, which has been corrected.

• Correct nr and alloc members of strvec struct to be of type size_t.

• "git stash", where the tentative change involves changing a directory to a file (or vice versa), was confused, which has been corrected.

• "git clone" from a repository whose HEAD is unborn into a bare repository didn’t follow the branch name the other side used, which is corrected.

• "git cvsserver" had a long-standing bug in its authentication code, which has finally been corrected (it is unclear and is a separate question if anybody is seriously using it, though).

• "git difftool --dir-diff" mishandled symbolic links.

• Sensitive data in the HTTP trace were supposed to be redacted, but we failed to do so in HTTP/2 requests.

• "make clean" has been updated to remove leftover .depend/ directories, even when it is not told to use them to compute header dependencies.

• Protocol v0 clients can get stuck parsing a malformed feature line.

Also contains various documentation updates and code clean-ups.
