Git 2.28 Release Notes
|
|
======================
|
|
|
|
Updates since v2.27
|
|
-------------------
|
|
|
|
Backward compatibility notes
|
|
|
|
* "fetch.writeCommitGraph" is deemed to be still a bit too risky and
|
|
is no longer part of the "feature.experimental" set.
|
|
|
|
|
|
UI, Workflows & Features
|
|
|
|
* The commands in the "diff" family learned to honor "diff.relative"
|
|
configuration variable.
|
|
|
|
* The check in "git fsck" to ensure that the tree objects are sorted
|
|
still had corner cases it missed unsorted entries.
|
|
|
|
* The interface to redact sensitive information in the trace output
|
|
has been simplified.
|
|
|
|
* The command line completion (in contrib/) learned to complete
|
|
options that the "git switch" command takes.
|
|
|
|
* "git diff" used to take arguments in random and nonsense range
|
|
notation, e.g. "git diff A..B C", "git diff A..B C...D", etc.,
|
|
which has been cleaned up.
|
|
|
|
* "git diff-files" has been taught to say paths that are marked as
|
|
intent-to-add are new files, not modified from an empty blob.
|
|
|
|
* "git status" learned to report the status of sparse checkout.
|
|
|
|
* "git difftool" has trouble dealing with paths added to the index
|
|
with the intent-to-add bit.
|
|
|
|
* "git fast-export --anonymize" learned to take customized mapping to
|
|
allow its users to tweak its output more usable for debugging.
|
|
|
|
* The command line completion support (in contrib/) used to be
|
|
prepared to work with "set -u" but recent changes got a bit more
|
|
sloppy. This has been corrected.
|
|
|
|
* "git gui" now allows opening work trees from the start-up dialog.
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
|
|
* Code optimization for a common case.
|
|
(merge 8777616e4d an/merge-single-strategy-optim later to maint).
|
|
|
|
* We've adopted a convention that any on-stack structure can be
|
|
initialized to have zero values in all fields with "= { 0 }",
|
|
even when the first field happens to be a pointer, but sparse
|
|
complained that a null pointer should be spelled NULL for a long
|
|
time. Start using -Wno-universal-initializer option to squelch
|
|
it (the latest sparse has it on by default).
|
|
|
|
* "git log -L..." now takes advantage of the "which paths are touched
|
|
by this commit?" info stored in the commit-graph system.
|
|
|
|
* As FreeBSD is not the only platform whose regexp library reports
|
|
a REG_ILLSEQ error when fed invalid UTF-8, add logic to detect that
|
|
automatically and skip the affected tests.
|
|
|
|
* "git bugreport" learns to report what shell is in use.
|
|
|
|
* Support for GIT_CURL_VERBOSE has been rewritten in terms of
|
|
GIT_TRACE_CURL.
|
|
|
|
* Preliminary clean-ups around refs API, plus file format
|
|
specification documentation for the reftable backend.
|
|
|
|
* Workaround breakage in MSVC build, where "curl-config --cflags"
|
|
gives settings appropriate for GCC build.
|
|
|
|
* Code clean-up of "git clean" resulted in a fix of recent
|
|
performance regression.
|
|
|
|
* Code clean-up in the codepath that serves "git fetch" continues.
|
|
|
|
* "git merge-base --is-ancestor" is taught to take advantage of the
|
|
commit graph.
|
|
|
|
* Rewrite of parts of the scripted "git submodule" Porcelain command
|
|
continues; this time it is "git submodule set-branch" subcommand's
|
|
turn.
|
|
|
|
* The "fetch/clone" protocol has been updated to allow the server to
|
|
instruct the clients to grab pre-packaged packfile(s) in addition
|
|
to the packed object data coming over the wire.
|
|
|
|
* A misdesigned strbuf_write_fd() function has been retired.
|
|
|
|
* SHA-256 migration work continues, including CVS/SVN interface.
|
|
|
|
* A few fields in "struct commit" that do not have to always be
|
|
present have been moved to commit slabs.
|
|
|
|
* API cleanup for get_worktrees()
|
|
|
|
* By renumbering object flag bits, "struct object" managed to lose
|
|
bloated inter-field padding.
|
|
|
|
* The name of the primary branch in existing repositories, and the
|
|
default name used for the first branch in newly created
|
|
repositories, is made configurable, so that we can eventually wean
|
|
ourselves off of the hardcoded 'master'.
|
|
|
|
* The effort to avoid using test_must_fail on non-git command continues.
|
|
|
|
* In 2.28-rc0, we corrected a bug that some repository extensions are
|
|
honored by mistake even in a version 0 repositories (these
|
|
configuration variables in extensions.* namespace were supposed to
|
|
have special meaning in repositories whose version numbers are 1 or
|
|
higher), but this was a bit too big a change. The behaviour in
|
|
recent versions of Git where certain extensions.* were honored by
|
|
mistake even in version 0 repositories has been restored.
|
|
|
|
|
|
Fixes since v2.27
|
|
-----------------
|
|
|
|
* The "--prepare-p4-only" option of "git p4" is supposed to stop
|
|
after replaying one changeset, but kept going (by mistake?)
|
|
|
|
* The error message from "git checkout -b foo -t bar baz" was
|
|
confusing.
|
|
|
|
* Some repositories in the wild have commits that record nonsense
|
|
committer timezone (e.g. rails.git); "git fast-import" learned an
|
|
option to pass these nonsense timestamps intact to allow recreating
|
|
existing repositories as-is.
|
|
(merge d42a2fb72f en/fast-import-looser-date later to maint).
|
|
|
|
* The command line completion script (in contrib/) tried to complete
|
|
"git stash -p" as if it were "git stash push -p", but it was too
|
|
aggressive and also affected "git stash show -p", which has been
|
|
corrected.
|
|
(merge fffd0cf520 vs/complete-stash-show-p-fix later to maint).
|
|
|
|
* On-the-wire protocol v2 easily falls into a deadlock between the
|
|
remote-curl helper and the fetch-pack process when the server side
|
|
prematurely throws an error and disconnects. The communication has
|
|
been updated to make it more robust.
|
|
|
|
* "git checkout -p" did not handle a newly added path at all.
|
|
(merge 2c8bd8471a js/checkout-p-new-file later to maint).
|
|
|
|
* The code to parse "git bisect start" command line was lax in
|
|
validating the arguments.
|
|
(merge 4d9005ff5d cb/bisect-helper-parser-fix later to maint).
|
|
|
|
* Reduce memory usage during "diff --quiet" in a worktree with too
|
|
many stat-unmatched paths.
|
|
(merge d2d7fbe129 jk/diff-memuse-optim-with-stat-unmatch later to maint).
|
|
|
|
* The reflog entries for "git clone" and "git fetch" did not
|
|
anonymize the URL they operated on.
|
|
(merge 46da295a77 js/reflog-anonymize-for-clone-and-fetch later to maint).
|
|
|
|
* The behaviour of "sparse-checkout" in the state "git clone
|
|
--no-checkout" left was changed accidentally in 2.27, which has
|
|
been corrected.
|
|
|
|
* Use of negative pathspec, while collecting paths including
|
|
untracked ones in the working tree, was broken.
|
|
|
|
* The same worktree directory must be registered only once, but
|
|
"git worktree move" allowed this invariant to be violated, which
|
|
has been corrected.
|
|
(merge 810382ed37 es/worktree-duplicate-paths later to maint).
|
|
|
|
* The effect of sparse checkout settings on submodules is documented.
|
|
(merge e7d7c73249 en/sparse-with-submodule-doc later to maint).
|
|
|
|
* Code clean-up around "git branch" with a minor bugfix.
|
|
(merge dc44639904 dl/branch-cleanup later to maint).
|
|
|
|
* A branch name used in a test has been clarified to match what is
|
|
going on.
|
|
(merge 08dc26061f pb/t4014-unslave later to maint).
|
|
|
|
* An in-code comment in "git diff" has been updated.
|
|
(merge c592fd4c83 dl/diff-usage-comment-update later to maint).
|
|
|
|
* The documentation and some tests have been adjusted for the recent
|
|
renaming of "pu" branch to "seen".
|
|
(merge 6dca5dbf93 js/pu-to-seen later to maint).
|
|
|
|
* The code to push changes over "dumb" HTTP had a bad interaction
|
|
with the commit reachability code due to incorrect allocation of
|
|
object flag bits, which has been corrected.
|
|
(merge 64472d15e9 bc/http-push-flagsfix later to maint).
|
|
|
|
* "git send-email --in-reply-to=<msg>" did not use the In-Reply-To:
|
|
header with the value given from the command line, and let it be
|
|
overridden by the value on In-Reply-To: header in the messages
|
|
being sent out (if exists).
|
|
(merge f9f60d7066 ra/send-email-in-reply-to-from-command-line-wins later to maint).
|
|
|
|
* "git log -Lx,y:path --before=date" lost track of where the range
|
|
should be because it didn't take the changes made by the youngest
|
|
commits that are omitted from the output into account.
|
|
|
|
* When "fetch.writeCommitGraph" configuration is set in a shallow
|
|
repository and a fetch moves the shallow boundary, we wrote out
|
|
broken commit-graph files that do not match the reality, which has
|
|
been corrected.
|
|
|
|
* "git checkout" failed to catch an error from fstat() after updating
|
|
a path in the working tree.
|
|
(merge 35e6e212fd mt/entry-fstat-fallback-fix later to maint).
|
|
|
|
* When an aliased command, whose output is piped to a pager by git,
|
|
gets killed by a signal, the pager got into a funny state, which
|
|
has been corrected (again).
|
|
(merge c0d73a59c9 ta/wait-on-aliased-commands-upon-signal later to maint).
|
|
|
|
* The code to produce progress output from "git commit-graph --write"
|
|
had a few breakages, which have been fixed.
|
|
|
|
* Other code cleanup, docfix, build fix, etc.
|
|
(merge 2c31a7aa44 jx/pkt-line-doc-count-fix later to maint).
|
|
(merge d63ae31962 cb/t5608-cleanup later to maint).
|
|
(merge 788db145c7 dl/t-readme-spell-git-correctly later to maint).
|
|
(merge 45a87a83bb dl/python-2.7-is-the-floor-version later to maint).
|
