Git 2.24 Release Notes
======================
Updates since v2.23
-------------------
Backward compatibility note
* (no entry yet so far)
UI, Workflows & Features
* We now have an active interim maintainer for the Git-Gui part of
the system. Praise and thank Pratyush Yadav for volunteering.
* The command line parser learned "--end-of-options" notation; the
standard convention for scripters to have hardcoded set of options
first on the command line, and force the command to treat end-user
input as non-options, has been to use "--" as the delimiter, but
that would not work for commands that use "--" as a delimiter
between revs and pathspec.
* A mechanism to affect the default setting for a (related) group of
configuration variables is introduced.
* "git fetch" learned "--set-upstream" option to help those who first
clone from their private fork they intend to push to, add the true
upstream via "git remote add" and then "git fetch" from it.
* Device-tree files learned their own userdiff patterns.
(merge 3c81760bc6 sb/userdiff-dts later to maint).
* "git rebase --rebase-merges" learned to drive different merge
strategies and pass strategy specific options to them.
* A new "pre-merge-commit" hook has been introduced.
* Command line completion updates for "git -c var.name=val" have been
added.
* The lazy clone machinery has been taught that there can be more
than one promisor remote and consult them in order when downloading
missing objects on demand.
* The list-objects-filter API (used to create a sparse/lazy clone)
learned to take a combined filter specification.
Performance, Internal Implementation, Development Support etc.
* The code to write commit-graph over given commit object names has
been made a bit more robust.
* The first line of verbose output from each test piece now carries
the test name and number to help scanning with eyeballs.
* Further clean-up of the initialization code.
* xmalloc() used to have a mechanism to ditch memory and address
space resources as the last resort upon seeing an allocation
failure from the underlying malloc(), which made the code complex
and thread-unsafe with dubious benefit, as major memory resource
users already do limit their uses with various other mechanisms.
It has been simplified away.
* Unnecessary full-tree diff in "git log -L" machinery has been
optimized away.
* The http transport lacked some optimization the native transports
learned to avoid unnecessary ref advertisement, which has been
corrected.
Fixes since v2.23
-----------------
* "git grep --recurse-submodules" that looks at the working tree
files looked at the contents in the index in submodules, instead of
files in the working tree.
(merge 6a289d45c0 mt/grep-submodules-working-tree later to maint).
* Codepaths to walk tree objects have been audited for integer
overflows and hardened.
(merge 5aa02f9868 jk/tree-walk-overflow later to maint).
* "git pack-refs" can lose refs that are created while running, which
is getting corrected.
(merge a613d4f817 sc/pack-refs-deletion-racefix later to maint).
* "git checkout" and "git restore" to re-populate the index from a
tree-ish (typically HEAD) did not work correctly for a path that
was removed and then added again with the intent-to-add bit, when
the corresponding working tree file was empty. This has been
corrected.
* Compilation fix.
(merge 70597e8386 rs/nedalloc-fixlets later to maint).
* "git gui" learned to call the clean-up procedure before exiting.
(merge 0d88f3d2c5 py/git-gui-do-quit later to maint).
* We promoted the "indent heuristics" that decides where to split
diff hunks from experimental to the default a few years ago, but
some stale documentation still marked it as experimental, which has
been corrected.
(merge 64e5e1fba1 sg/diff-indent-heuristic-non-experimental later to maint).
* Fix a mismerge that happened in 2.22 timeframe.
(merge acb7da05ac en/checkout-mismerge-fix later to maint).
* "git archive" recorded incorrect length in extended pax header in
some corner cases, which has been corrected.
(merge 71d41ff651 rs/pax-extended-header-length-fix later to maint).
* On-demand object fetching in lazy clone incorrectly tried to fetch
commits from submodule projects, while still working in the
superproject, which has been corrected.
(merge a63694f523 jt/diff-lazy-fetch-submodule-fix later to maint).
* Prepare get_short_oid() codepath to be thread-safe.
(merge 7cfcb16b0e rs/sort-oid-array-thread-safe later to maint).
* "for-each-ref" and friends that show refs did not protect themselves
against ancient tags that did not record tagger names when asked to
show "%(taggername)", which have been corrected.
(merge 8b3f33ef11 mp/for-each-ref-missing-name-or-email later to maint).
* The "git am" based backend of "git rebase" ignored the result of
updating ".gitattributes" done in one step when replaying
subsequent steps.
(merge 2c65d90f75 bc/reread-attributes-during-rebase later to maint).
* Tell cURL library to use the same malloc() implementation, with the
xmalloc() wrapper, as the rest of the system, for consistency.
(merge 93b980e58f cb/curl-use-xmalloc later to maint).
* Other code cleanup, docfix, build fix, etc.
(merge d1387d3895 en/fast-import-merge-doc later to maint).
(merge 1c24a54ea4 bm/repository-layout-typofix later to maint).
(merge 415b770b88 ds/midx-expire-repack later to maint).
(merge 19800bdc3f nd/diff-parseopt later to maint).
(merge 58166c2e9d tg/t0021-racefix later to maint).
