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.
