Git 2.22 Release Notes
|
|
======================
|
|
|
|
Updates since v2.21
|
|
-------------------
|
|
|
|
UI, Workflows & Features
|
|
|
|
* "git checkout --no-overlay" can be used to trigger a new mode of
|
|
checking out paths out of the tree-ish, that allows paths that
|
|
match the pathspec that are in the current index and working tree
|
|
and are not in the tree-ish.
|
|
|
|
* The %(trailers) formatter in "git log --format=..." now allows to
|
|
optionally pick trailers selectively by keyword, show only values,
|
|
etc.
|
|
|
|
* Four new configuration variables {author,committer}.{name,email}
|
|
have been introduced to override user.{name,email} in more specific
|
|
cases.
|
|
|
|
* Command-line completion (in contrib/) learned to tab-complete the
|
|
"git submodule absorbgitdirs" subcommand.
|
|
|
|
* "git branch" learned a new subcommand "--show-current".
|
|
|
|
* Output from "diff --cc" did not show the original paths when the
|
|
merge involved renames. A new option adds the paths in the
|
|
original trees to the output.
|
|
|
|
* The command line completion (in contrib/) has been taught to
|
|
complete more subcommand parameters.
|
|
|
|
* The final report from "git bisect" used to show the suspected
|
|
culprit using a raw "diff-tree", with which there is no output for
|
|
a merge commit. This has been updated to use a more modern and
|
|
human readable output that still is concise enough.
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
|
|
* The diff machinery, one of the oldest parts of the system, which
|
|
long predates the parse-options API, uses fairly long and complex
|
|
handcrafted option parser. This is being rewritten to use the
|
|
parse-options API.
|
|
|
|
* The implementation of pack-redundant has been updated for
|
|
performance in a repository with many packfiles.
|
|
|
|
* A more structured way to obtain execution trace has been added.
|
|
|
|
* "git prune" has been taught to take advantage of reachability
|
|
bitmap when able.
|
|
|
|
* The command line parser of "git commit-tree" has been rewritten to
|
|
use the parse-options API.
|
|
|
|
|
|
Fixes since v2.21
|
|
-----------------
|
|
|
|
* "git prune-packed" did not notice and complain against excess
|
|
arguments given from the command line, which now it does.
|
|
(merge 9b0bd87ed2 rj/prune-packed-excess-args later to maint).
|
|
|
|
* Split-index fix.
|
|
(merge 6e37c8ed3c nd/split-index-null-base-fix later to maint).
|
|
|
|
* "git diff --no-index" may still want to access Git goodies like
|
|
--ext-diff and --textconv, but so far these have been ignored,
|
|
which has been corrected.
|
|
(merge 287ab28bfa jk/diff-no-index-initialize later to maint).
|
|
|
|
* Unify RPC code for smart http in protocol v0/v1 and v2, which fixes
|
|
a bug in the latter (lack of authentication retry) and generally
|
|
improves the code base.
|
|
(merge a97d00799a jt/http-auth-proto-v2-fix later to maint).
|
|
|
|
* The include file compat/bswap.h has been updated so that it is safe
|
|
to (accidentally) include it more than once.
|
|
(merge 33aa579a55 jk/guard-bswap-header later to maint).
|
|
|
|
* The set of header files used by "make hdr-check" unconditionally
|
|
included sha256/gcrypt.h, even when it is not used, causing the
|
|
make target to fail. We now skip it when GCRYPT_SHA256 is not in
|
|
use.
|
|
(merge f23aa18e7f rj/hdr-check-gcrypt-fix later to maint).
|
|
|
|
* The Makefile uses 'find' utility to enumerate all the *.h header
|
|
files, which is expensive on platforms with slow filesystems; it
|
|
now optionally uses "ls-files" if working within a repository,
|
|
which is a trick similar to how all sources are enumerated to run
|
|
ETAGS on.
|
|
(merge 92b88eba9f js/find-lib-h-with-ls-files-when-possible later to maint).
|
|
|
|
* "git rebase" that was reimplemented in C did not set ORIG_HEAD
|
|
correctly, which has been corrected.
|
|
(merge cbd29ead92 js/rebase-orig-head-fix later to maint).
|
|
|
|
* Dev support.
|
|
(merge f545737144 js/stress-test-ui-tweak later to maint).
|
|
|
|
* CFLAGS now can be tweaked when invoking Make while using
|
|
DEVELOPER=YesPlease; this did not work well before.
|
|
(merge 6d5d4b4e93 ab/makefile-help-devs-more later to maint).
|
|
|
|
* "git fsck --connectivity-only" omits computation necessary to sift
|
|
the objects that are not reachable from any of the refs into
|
|
unreachable and dangling. This is now enabled when dangling
|
|
objects are requested (which is done by default, but can be
|
|
overridden with the "--no-dangling" option).
|
|
(merge 8d8c2a5aef jk/fsck-doc later to maint).
|
|
|
|
* On platforms where "git fetch" is killed with SIGPIPE (e.g. OSX),
|
|
the upload-pack that runs on the other end that hangs up after
|
|
detecting an error could cause "git fetch" to die with a signal,
|
|
which led to a flakey test. "git fetch" now ignores SIGPIPE during
|
|
the network portion of its operation (this is not a problem as we
|
|
check the return status from our write(2)s).
|
|
(merge 143588949c jk/no-sigpipe-during-network-transport later to maint).
|
|
|
|
* A recent update broke "is this object available to us?" check for
|
|
well-known objects like an empty tree (which should yield "yes",
|
|
even when there is no on-disk object for an empty tree), which has
|
|
been corrected.
|
|
(merge f06ab027ef jk/virtual-objects-do-exist later to maint).
|
|
|
|
* The setup code has been cleaned up to avoid leaks around the
|
|
repository_format structure.
|
|
(merge e8805af1c3 ma/clear-repository-format later to maint).
|
|
|
|
* "git config --type=color ..." is meant to replace "git config --get-color"
|
|
but there is a slight difference that wasn't documented, which is
|
|
now fixed.
|
|
(merge cd8e7593b9 jk/config-type-color-ends-with-lf later to maint).
|
|
|
|
* Code cleanup, docfix, build fix, etc.
|
|
(merge 11f470aee7 jc/test-yes-doc later to maint).
|
|
(merge 90503a240b js/doc-symref-in-proto-v1 later to maint).
|
|
(merge 5c326d1252 jk/unused-params later to maint).
|
|
(merge 68cabbfda3 dl/doc-submodule-wo-subcommand later to maint).
|
|
(merge 9903623761 ab/receive-pack-use-after-free-fix later to maint).
|
|
(merge 1ede45e44b en/merge-options-doc later to maint).
|
