Git v2.39 Release Notes
|
|
=======================
|
|
|
|
UI, Workflows & Features
|
|
------------------------
|
|
|
|
* "git grep" learned to expand the sparse-index more lazily and on
|
|
demand in a sparse checkout.
|
|
|
|
* By default, use of fsmonitor on a repository on networked
|
|
filesystem is disabled. Add knobs to make it workable on macOS.
|
|
|
|
* After checking out a "branch" that is a symbolic-ref that points at
|
|
another branch, "git symbolic-ref HEAD" reports the underlying
|
|
branch, not the symbolic-ref the user gave checkout as argument.
|
|
The command learned the "--no-recurse" option to stop after
|
|
dereferencing a symbolic-ref only once.
|
|
|
|
* "git branch --edit-description @{-1}" is now a way to edit branch
|
|
description of the branch you were on before switching to the
|
|
current branch.
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
--------------------------------------------------------------
|
|
|
|
* With a bit of header twiddling, use the native regexp library on
|
|
macOS instead of the compat/ one.
|
|
|
|
* Prepare for GNU [ef]grep that throw warning of their uses.
|
|
|
|
* Sources related to fuzz testing have been moved down to their own
|
|
directory.
|
|
|
|
* Most credential helpers ignored unknown entries in a credential
|
|
description, but a few died upon seeing them. The latter were
|
|
taught to ignore them, too
|
|
|
|
* "scalar unregister" in a repository that is already been
|
|
unregistered reported an error.
|
|
|
|
* Remove error detection from a function that fetches from promisor
|
|
remotes, and make it die when such a fetch fails to bring all the
|
|
requested objects, to give an early failure to various operations.
|
|
|
|
* Update CodingGuidelines to clarify what features to use and avoid
|
|
in C99.
|
|
|
|
* Avoid false-positive from LSan whose assumption may be broken with
|
|
higher optimization levels.
|
|
|
|
* Enable address and undefined sanitizer tasks at GitHub Actions CI.
|
|
|
|
|
|
Fixes since v2.38
|
|
-----------------
|
|
|
|
* The codepath that reads from the index v4 had unaligned memory
|
|
accesses, which has been corrected.
|
|
|
|
* Fix messages incorrectly marked for translation.
|
|
|
|
* "git fsck" failed to release contents of tree objects already used
|
|
from the memory, which has been fixed.
|
|
|
|
* "git clone" did not like to see the "--bare" and the "--origin"
|
|
options used together without a good reason.
|
|
|
|
* "git remote rename" failed to rename a remote without fetch
|
|
refspec, which has been corrected.
|
|
|
|
* Documentation on various Boolean GIT_* environment variables have
|
|
been clarified.
|
|
(merge 819fb68222 jc/environ-docs later to maint).
|
|
|
|
* "git rebase -i" can mistakenly attempt to apply a fixup to a commit
|
|
itself, which has been corrected.
|
|
|
|
* "git multi-pack-index repack/expire" used to repack unreachable
|
|
cruft into a new pack, which have been corrected.
|
|
(merge b62ad5681f tb/midx-repack-ignore-cruft-packs later to maint).
|
|
|
|
* In read-only repositories, "git merge-tree" tried to come up with a
|
|
merge result tree object, which it failed (which is not wrong) and
|
|
led to a segfault (which is bad), which has been corrected.
|
|
|
|
* Force C locale while running tests around httpd to make sure we can
|
|
find expected error messages in the log.
|
|
|
|
* Fix a logic in "mailinfo -b" that miscomputed the length of a
|
|
substring, which lead to an out-of-bounds access.
|
|
|
|
* The codepath to sign learned to report errors when it fails to read
|
|
from "ssh-keygen".
|
|
|
|
* Code clean-up that results in plugging a leak.
|
|
|
|
* "GIT_EDITOR=: git branch --edit-description" resulted in failure,
|
|
which has been corrected.
|
|
|
|
* The code to clean temporary object directories (used for
|
|
quarantine) tried to remove them inside its signal handler, which
|
|
was a no-no.
|
|
(merge 22613b25ec jc/tmp-objdir later to maint).
|
|
|
|
* Update comment in the Makefile about the RUNTIME_PREFIX config knob.
|
|
(merge ebb6c16607 dd/document-runtime-prefix-better later to maint).
|
|
|
|
* Clarify that "the sentence after <area>: prefix does not begin with
|
|
a capital letter" rule applies only to the commit title.
|
|
(merge 3991bb73dd jc/use-of-uc-in-log-messages later to maint).
|
|
|
|
* "git branch --edit-description" on an unborh branch misleadingly
|
|
said that no such branch exists, which has been corrected.
|
|
(merge bcfc82bd48 rj/branch-edit-desc-unborn later to maint).
|
|
|
|
* Work around older clang that warns against C99 zero initialization
|
|
syntax for struct.
|
|
(merge 54795d37d9 jh/struct-zero-init-with-older-clang later to maint).
|
|
|
|
* Giving "--invert-grep" and "--all-match" without "--grep" to the
|
|
"git log" command resulted in an attempt to access grep pattern
|
|
expression structure that has not been allocated, which has been
|
|
corrected.
|
|
(merge db84376f98 ab/grep-simplify-extended-expression later to maint).
|
|
|
|
* "git diff rev^!" did not show combined diff to go to the rev from
|
|
its parents.
|
|
(merge a79c6b6081 rs/diff-caret-bang-with-parents later to maint).
|
|
|
|
* Allow configuration files in "protected" scopes to include other
|
|
configuration files.
|
|
(merge ecec57b3c9 gc/bare-repo-discovery later to maint).
|
|
|
|
* Give a bit more diversity to macOS CI by using sha1dc in one of the
|
|
jobs (the other one tests Apple Common Crypto).
|
|
(merge 1ad5c3df35 jc/ci-osx-with-sha1dc later to maint).
|
|
|
|
* Other code cleanup, docfix, build fix, etc.
|
|
(merge c34a6bd291 so/diff-merges-cleanup later to maint).
|
|
(merge 2a905f8fa8 ah/branch-autosetupmerge-grammofix later to maint).
