Git 2.35 Release Notes
======================

Updates since Git 2.34
----------------------

Backward compatibility warts

 * "_" is now treated as any other URL-valid characters in an URL when
   matching the per-URL configuration variable names.


UI, Workflows & Features

 * "git status --porcelain=v2" now show the number of stash entries
   with --show-stash like the normal output does.

 * "git stash" learned the "--staged" option to stash away what has
   been added to the index (and nothing else).

 * "git var GIT_DEFAULT_BRANCH" is a way to see what name is used for
   the newly created branch if "git init" is run.

 * Various operating modes of "git reset" have been made to work
   better with the sparse index.

 * "git submodule deinit" for a submodule whose .git metadata
   directory is embedded in its working tree refused to work, until
   the submodule gets converted to use the "absorbed" form where the
   metadata directory is stored in superproject, and a gitfile at the
   top-level of the working tree of the submodule points at it.  The
   command is taught to convert such submodules to the absorbed form
   as needed.

 * The completion script (in contrib/) learns that the "--date"
   option of commands from the "git log" family takes "human" and
   "auto" as valid values.


Performance, Internal Implementation, Development Support etc.

 * The use of errno as a means to carry the nature of error in the ref
   API implementation has been reworked and reduced.

 * Teach and encourage first-time contributors to this project to
   state the base commit when they submit their topic.

 * The command line complation for "git send-email" options have been
   tweaked to make it easier to keep it in sync with the command itself.


 * Ensure that the sparseness of the in-core index matches the
   index.sparse configuration specified by the repository immediately
   after the on-disk index file is read.

 * Code clean-up to eventually allow information on remotes defined
   for an arbitrary repository to be read.

 * Build optimization.

 * Tighten code for testing pack-bitmap.

 * Weather balloon to break people with compilers that do not support
   C99.


Fixes since v2.34
-----------------

 * "git grep" looking in a blob that has non-UTF8 payload was
   completely broken when linked with certain versions of PCREv2
   library in the latest release.

 * Other code cleanup, docfix, build fix, etc.

 * "git pull" with any strategy when the other side is behind us
   should succeed as it is a no-op, but doesn't.

 * An earlier change in 2.34.0 caused JGit application (that abused
   GIT_EDITOR mechanism when invoking "git config") to get stuck with
   a SIGTTOU signal; it has been reverted.

 * An earlier change that broke .gitignore matching has been reverted.

 * Things like "git -c branch.sort=bogus branch new HEAD", i.e. the
   operation modes of the "git branch" command that do not need the
   sort key information, no longer errors out by seeing a bogus sort
   key.
   (merge 98e7ab6d42 jc/fix-ref-sorting-parse later to maint).

 * The compatibility implementation for unsetenv(3) were written to
   mimic ancient, non-POSIX, variant seen in an old glibc; it has been
   changed to return an integer to match the more modern era.
   (merge a38989bd5b jc/unsetenv-returns-an-int later to maint).

 * The clean/smudge conversion code path has been prepared to better
   work on platforms where ulong is narrower than size_t.
   (merge 596b5e77c9 mc/clean-smudge-with-llp64 later to maint).

 * Redact the path part of packfile URI that appears in the trace output.
   (merge 0ba558ffb1 if/redact-packfile-uri later to maint).

 * CI has been taught to catch some Unicode directional formatting
   sequence that can be used in certain mischief.
   (merge 0e7696c64d js/ci-no-directional-formatting later to maint).

 * The "--date=format:<strftime>" gained a workaround for the lack of
   system support for a non-local timezone to handle "%s" placeholder.
   (merge 9b591b9403 jk/strbuf-addftime-seconds-since-epoch later to maint).

 * The "merge" subcommand of "git jump" (in contrib/) silently ignored
   pathspec and other parameters.
   (merge 67ba13e5a4 jk/jump-merge-with-pathspec later to maint).

 * The code to decode the length of packed object size has been
   corrected.
   (merge 34de5b8eac jt/pack-header-lshift-overflow later to maint).

 * The advice message given by "git pull" when the user hasn't made a
   choice between merge and rebase still said that the merge is the
   default, which no longer is the case.  This has been corrected.
   (merge 71076d0edd ah/advice-pull-has-no-preference-between-rebase-and-merge later to maint).

 * "git fetch", when received a bad packfile, can fail with SIGPIPE.
   This wasn't wrong per-se, but we now detect the situation and fail
   in a more predictable way.
   (merge 2a4aed42ec jk/fetch-pack-avoid-sigpipe-to-index-pack later to maint).

 * The function to cull a child process and determine the exit status
   had two separate code paths for normal callers and callers in a
   signal handler, and the latter did not yield correct value when the
   child has caught a signal.  The handling of the exit status has
   been unified for these two code paths.  An existing test with
   flakiness has also been corrected.
   (merge 5263e22cba jk/t7006-sigpipe-tests-fix later to maint).

 * When a non-existent program is given as the pager, we tried to
   reuse an uninitialized child_process structure and crashed, which
   has been fixed.
   (merge f917f57f40 em/missing-pager later to maint).

 * The single-key-input mode in "git add -p" had some code to handle
   keys that generate a sequence of input via ReadKey(), which did not
   handle end-of-file correctly, which has been fixed.
   (merge fc8a8126df cb/add-p-single-key-fix later to maint).

 * "git rebase -x" added an unnecessary 'exec' instructions before
   'noop', which has been corrected.
   (merge cc9dcdee61 en/rebase-x-fix later to maint).

 * Other code cleanup, docfix, build fix, etc.
   (merge 74db416c9c cw/protocol-v2-doc-fix later to maint).
   (merge f9b2b6684d ja/doc-cleanup later to maint).
   (merge 7d1b866778 jc/fix-first-object-walk later to maint).
   (merge 538ac74604 js/trace2-avoid-recursive-errors later to maint).
   (merge 152923b132 jk/t5319-midx-corruption-test-deflake later to maint).
