Git v2.49 Release Notes
=======================
UI, Workflows & Features
------------------------
* Completion script updates for zsh
Performance, Internal Implementation, Development Support etc.
--------------------------------------------------------------
* More -Wsign-compare fixes.
* meson-based build now supports the unsafe-sha1 build knob.
* The code to check LSan results has been simplified and made more
robust.
(merge 164a2516eb jk/lsan-race-ignore-false-positive later to maint).
* More code paths have a repository passed through the callchain,
instead of assuming the primary the_repository object.
* Move a few more unit tests to the clar test framework.
* Introduce a new API to visit objects in batches based on a common
path, or by type.
Fixes since v2.48
-----------------
* "git submodule" learned various ways to spell the same option,
e.g. "--branch=B" can be spelled "--branch B" or "-bB".
(merge b86f0f9071 re/submodule-parse-opt later to maint).
* Tweak the help text used for the option value placeholders by
parse-options API so that translations can customize the "<>"
placeholder signal (e.g. "--option=<value>").
(merge 5b34dd08d0 as/long-option-help-i18n later to maint).
* CI jobs gave sporadic failures, which turns out that that the
object finalization code was giving an error when it did not have
to.
(merge d7fcbe2c56 ps/object-collision-check later to maint).
* The code to compute "unique" name used git_rand() which can fail or
get stuck; the callsite does not require cryptographic security.
Introduce the "insecure" mode and use it appropriately.
(merge 0b4f8afef6 ps/reftable-get-random-fix later to maint).
* A misconfigured "fsck.skiplist" configuration variable was not
diagnosed as an error, which has been corrected.
(merge ca7158076f jt/fsck-skiplist-parse-fix later to maint).
* Extended SHA-1 expression parser did not work well when a branch
with an unusual name (e.g. "foo{bar") is involved.
(merge 191f0c8db2 en/object-name-with-funny-refname-fix later to maint).
* The meson build procedure looked for the 'version-def.h' file in a
wrong directory, which has been corrected.
(merge 4771501c0a tc/meson-use-our-version-def-h later to maint).
* The meson build procedure for Documentation/technical/ hierarchy was
missing necessary dependencies, which has been corrected.
(merge 1dca492edd sj/meson-doc-technical-dependency-fix later to maint).
* The "instaweb" bound only to local IP address without "--local" and
to all addresses with "--local", which was the other way around, when
using Python's http.server class, which has been corrected.
(merge 76baf97fa1 ak/instaweb-python-port-binding-fix later to maint).
* Document that it is insecure to use Personal Access Tokens, which
some hosting providers take as username/password, embedded in URLs.
(merge a90ff409f0 mh/doc-credential-helpers-with-pat later to maint).
* The help text from "git $cmd -h" appear on the standard output for
some $cmd and the standard error for others. The built-in commands
have been fixed to show them on the standard output consistently.
(merge f66d1423f5 jc/show-usage-help later to maint).
* The meson-driven build is now aware of "git-subtree" housed in
contrib/subtree hierarchy.
(merge 8454b42f94 ps/build-meson-subtree later to maint).
* It was possible for "git unpack-objects" and "git index-pack" to
make an unaligned access, which has been corrected.
(merge 98046591b9 jk/pack-header-parse-alignment-fix later to maint).
* The "cache" credential back-end did not handle authtype correctly,
which has been corrected.
(merge 0b43274850 mh/credential-cache-authtype-request-fix later to maint).
* "git branch --sort=..." and "git for-each-ref --format=... --sort=..."
did not work as expected with some atoms, which has been corrected.
(merge c5490ce9d1 rs/ref-fitler-used-atoms-value-fix later to maint).
* reflog entries for symbolic ref updates were broken, which has been
corrected.
(merge 3519492430 kn/reflog-symref-fix later to maint).
* The trace2 code was not prepared to show a configuration variable
that is set to true using the valueless true syntax, which has been
corrected.
(merge 2fd367cf63 am/trace2-with-valueless-true later to maint).
* The "git refs migrate" command did not migrate the reflog for
refs/stash, which is the contents of the stashes, which has been
corrected.
(merge a0bea0978f ps/reflog-migration-with-logall-fix later to maint).
* Other code cleanup, docfix, build fix, etc.
(merge ddb5287894 jk/t7407-use-test-grep later to maint).
(merge 21e1b44865 aj/difftool-config-doc-fix later to maint).
(merge 6a63995335 mh/gitattr-doc-markup-fix later to maint).
(merge 43850dcf9c sk/unit-test-hash later to maint).
(merge 4ad47d2de3 jc/cli-doc-option-and-config later to maint).
(merge 2d0ff147e5 jp/t8002-printf-fix later to maint).
