Git v2.48 Release Notes
=======================
UI, Workflows & Features
------------------------
* A new configuration variable remote.<name>.serverOption makes the
transport layer act as if the --serverOption=<value> option is
given from the command line.
* "git rebase --rebase-merges" now uses branch names as labels when
able.
* Describe the policy to introduce breaking changes.
* Teach 'git notes add' and 'git notes append' a new '-e' flag,
instructing them to open the note in $GIT_EDITOR before saving.
Performance, Internal Implementation, Development Support etc.
--------------------------------------------------------------
* Document "amlog" notes.
(merge ddfb5bcfc6 tb/notes-amlog-doc later to maint).
* The way AsciiDoc is used for SYNOPSIS part of the manual pages has
been revamped. The sources, at least for the simple cases, got
vastly pleasant to work with.
* The reftable library is now prepared to expect that the memory
allocation function given to it may fail to allocate and to deal
with such an error.
* An extra worktree attached to a repository points at each other to
allow finding the repository from the worktree and vice versa
possible. Turn this linkage to relative paths.
* Enable Windows-based CI in GitLab.
* Commands that can also work outside Git have learned to take the
repository instance "repo" when we know we are in a repository, and
NULL when we are not, in a parameter. The uses of the_repository
variable in a few of them have been removed using the new calling
convention.
* The reftable sub-system grew a new reftable-specific strbuf
replacement to reduce its dependency on Git-specific data
structures.
* The ref-filter machinery learns to recognize and avoid cases where
sorting would be redundant.
* Various platform compatibility fixes split out of the larger effort
to use Meson as the primary build tool.
* Treat ECONNABORTED the same as ECONNRESET in 'git credential-cache'
to work around a possible Cygwin regression. This resolves a race
condition caused by changes in Cygwin's handling of socket
closures, allowing the client to exit cleanly when encountering
ECONNABORTED.
* Demonstrate an assertion failure in 'git mv'.
* Documentation update to clarify that 'uploadpack.allowAnySHA1InWant'
implies both 'allowTipSHA1InWant' and 'allowReachableSHA1InWant'.
* Replace various calls to atoi() with strtol_i() and strtoul_ui(),
and add improved error handling.
* Documentation updates to 'git-update-ref(1)'.
* Update the project's CodingGuidelines to discourage naming functions
with a "_1()" suffix.
* Updates the '.clang-format' to match project conventions.
* Centralize documentation for repository extensions into a single place.
* Buildfix and upgrade of Clar to a newer version.
* Documentation mark-up updates.
* Renaming a handful of variables and structure fields.
Fixes since v2.47
-----------------
* Doc update to clarify how periodical maintenance are scheduled,
spread across time to avoid thundering hurds.
(merge 3d6ab4177d sk/doc-maintenance-schedule later to maint).
* Use after free and double freeing at the end in "git log -L... -p"
had been identified and fixed.
* On macOS, fsmonitor can fall into a race condition that results in
a client waiting forever to be notified for an event that have
already happened. This problem has been corrected.
* "git maintenance start" crashed due to an uninitialized variable
reference, which has been corrected.
* Fail gracefully instead of crashing when attempting to write the
contents of a corrupt in-core index as a tree object.
* A "git fetch" from the superproject going down to a submodule used
a wrong remote when the default remote names are set differently
between them.
* Fixes compile time warnings with 64-bit MSVC.
* Teaches 'shortlog' to explicitly use SHA-1 when operating outside
of a repository.
* Fix 'git grep' regression on macOS by disabling lookahead when
encountering invalid UTF-8 byte sequences.
* The dumb-http code regressed when the result of re-indexing a pack
yielded an *.idx file that differs in content from the *.idx file
it downloaded from the remote. This has been corrected by no longer
relying on: the *.idx file we got from the remote.
* When called with '--left-right' and '--use-bitmap-index', 'rev-list'
will produce output without any left/right markers, which has been
corrected.
* More leakfixes.
* Test modernization.
* The "--shallow-exclude=<ref>" option to various history transfer
commands takes a ref, not an arbitrary revision.
* A regression where commit objects missing from a commit-graph can
cause an infinite loop when doing a fetch in a partial clone has
been fixed.
* The MinGW compatibility layer has been taught to support POSIX
semantics for atomic renames when other process(es) have a file
opened at the destination path.
* "git gc" discards any objects that are outside promisor packs that
are referred to by an object in a promisor pack, and we do not
refetch them from the promisor at runtime, resulting an unusable
repository. Work it around by including these objects in the
referring promisor pack at the receiving end of the fetch.
* Avoid build/test breakage on a system without working malloc debug
support dynamic library.
(merge 72ad6dc368 jk/test-malloc-debug-check later to maint).
* Double-free fix.
(merge fe17a25905 jk/fetch-prefetch-double-free-fix later to maint).
* Use of some uninitialized variables in "git difftool" has been
corrected.
* Object reuse code based on multi-pack-index sent an unwanted copy
of object.
(merge e199290592 tb/multi-pack-reuse-dupfix later to maint).
* Other code cleanup, docfix, build fix, etc.
(merge 1164e270b5 jk/output-prefix-cleanup later to maint).
