Git 2.7 Release Notes
|
|
=====================
|
|
|
|
Updates since v2.6
|
|
------------------
|
|
|
|
UI, Workflows & Features
|
|
|
|
* "git remote" learned "get-url" subcommand to show the URL for a
|
|
given remote name used for fetching and pushing.
|
|
|
|
* There was no way to defeat a configured rebase.autostash variable
|
|
from the command line, as "git rebase --no-autostash" was missing.
|
|
|
|
* "git log --date=local" used to only show the normal (default)
|
|
format in the local timezone. The command learned to take 'local'
|
|
as an instruction to use the local timezone with other formats,
|
|
|
|
* The refs used during a "git bisect" session is now per-worktree so
|
|
that independent bisect sessions can be done in different worktrees
|
|
created with "git worktree add".
|
|
|
|
* Users who are too busy to type three extra keystrokes to ask for
|
|
"git stash show -p" can now set stash.showPatch configuration
|
|
varible to true to always see the actual patch, not just the list
|
|
of paths affected with feel for the extent of damage via diffstat.
|
|
|
|
* "quiltimport" allows to specify the series file by honoring the
|
|
$QUILT_SERIES environment and also --series command line option.
|
|
|
|
* The use of 'good/bad' in "git bisect" made it confusing to use when
|
|
hunting for a state change that is not a regression (e.g. bugfix).
|
|
The command learned 'old/new' and then allows the end user to
|
|
say e.g. "bisect start --term-old=fast --term=new=slow" to find a
|
|
performance regression.
|
|
|
|
* "git interpret-trailers" can now run outside of a Git repository.
|
|
|
|
* "git p4" learned to reencode the pathname it uses to communicate
|
|
with the p4 depot with a new option.
|
|
|
|
* Give progress meter to "git filter-branch".
|
|
|
|
* Allow a later "!/abc/def" to override an earlier "/abc" that
|
|
appears in the same .gitignore file to make it easier to express
|
|
"everything in /abc directory is ignored, except for ...".
|
|
|
|
* Teach "git p4" to send large blobs outside the repository by
|
|
talking to Git LFS.
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
|
|
* The infrastructure to rewrite "git submodule" in C is being built
|
|
incrementally. Let's polish these early parts well enough and make
|
|
them graduate to 'next' and 'master', so that the more involved
|
|
follow-up can start cooking on a solid ground.
|
|
|
|
* Some features from "git tag -l" and "git branch -l" have been made
|
|
available to "git for-each-ref" so that eventually the unified
|
|
implementation can be shared across all three.
|
|
|
|
* Because "test_when_finished" in our test framework queues the
|
|
clean-up tasks to be done in a shell variable, it should not be
|
|
used inside a subshell. Add a mechanism to allow 'bash' to catch
|
|
such uses, and fix the ones that were found.
|
|
(merge 0968f12 jk/test-lint-forbid-when-finished-in-subshell later to maint).
|
|
|
|
* The debugging infrastructure for pkt-line based communication has
|
|
been improved to mark the side-band communication specifically.
|
|
(merge fd89433 jk/async-pkt-line later to maint).
|
|
|
|
* Update "git branch" that list existing branches, using the
|
|
ref-filter API that is shared with "git tag" and "git
|
|
for-each-ref".
|
|
|
|
|
|
Also contains various documentation updates and code clean-ups.
|
|
|
|
|
|
Fixes since v2.6
|
|
----------------
|
|
|
|
Unless otherwise noted, all the fixes since v2.6 in the maintenance
|
|
track are contained in this release (see the maintenance releases'
|
|
notes for details).
|
|
|
|
* Very small number of options take a parameter that is optional
|
|
(which is not a great UI element as they can only appear at the end
|
|
of the command line). Add notice to documentation of each and
|
|
every one of them.
|
|
(merge 2b594bf mm/keyid-docs later to maint).
|
|
|
|
* "git blame --first-parent v1.0..v2.0" was not rejected but did not
|
|
limit the blame to commits on the first parent chain.
|
|
(merge 95a4fb0 jk/blame-first-parent later to maint).
|
|
|
|
* "git subtree" (in contrib/) now can take whitespaces in the
|
|
pathnames, not only in the in-tree pathname but the name of the
|
|
directory that the repository is in. (merge 5b6ab38
|
|
as/subtree-with-spaces later to maint).
|
|
|
|
* The ssh transport, just like any other transport over the network,
|
|
did not clear GIT_* environment variables, but it is possible to
|
|
use SendEnv and AcceptEnv to leak them to the remote invocation of
|
|
Git, which is not a good idea at all. Explicitly clear them just
|
|
like we do for the local transport.
|
|
(merge a48b409 jk/connect-clear-env later to maint).
|
|
|
|
* Correct "git p4 --detect-labels" so that it does not fail to create
|
|
a tag that points at a commit that is also being imported.
|
|
(merge b43702a ld/p4-import-labels later to maint).
|
|
|
|
* The Makefile always runs the library archiver with hardcoded "crs"
|
|
options, which was inconvenient for exotic platforms on which
|
|
people want to use programs with totally different set of command
|
|
line options.
|
|
(merge ac179b4 jw/make-arflags-customizable later to maint).
|
|
|
|
* Customization to change the behaviour with "make -w" and "make -s"
|
|
in our Makefile was broken when they were used together.
|
|
(merge ef49e05 jk/make-findstring-makeflags-fix later to maint).
|
|
|
|
* Allocation related functions and stdio are unsafe things to call
|
|
inside a signal handler, and indeed killing the pager can cause
|
|
glibc to deadlock waiting on allocation mutex as our signal handler
|
|
tries to free() some data structures in wait_for_pager(). Reduce
|
|
these unsafe calls.
|
|
(merge 507d780 ti/glibc-stdio-mutex-from-signal-handler later to maint).
|
|
|
|
* The way how --ref/--notes to specify the notes tree reference are
|
|
DWIMmed was not clearly documented.
|
|
(merge e14c92e jk/notes-dwim-doc later to maint).
|
|
|
|
* "git gc" used to barf when a symbolic ref has gone dangling
|
|
(e.g. the branch that used to be your upstream's default when you
|
|
cloned from it is now gone, and you did "fetch --prune").
|
|
(merge 14886b4 js/gc-with-stale-symref later to maint).
|
|
|
|
* "git clone --dissociate" runs a big "git repack" process at the
|
|
end, and it helps to close file descriptors that are open on the
|
|
packs and their idx files before doing so on filesystems that
|
|
cannot remove a file that is still open.
|
|
(merge 786b150 js/clone-dissociate later to maint).
|
|
|
|
* Description of the "log.follow" configuration variable in "git log"
|
|
documentation is now also copied to "git config" documentation.
|
|
(merge fd8d07e dt/log-follow-config later to maint).
|
|
|
|
* "git rebase -i" had a minor regression recently, which stopped
|
|
considering a line that begins with an indented '#' in its insn
|
|
sheet not a comment, which is now fixed.
|
|
(merge 1db168e gr/rebase-i-drop-warn later to maint).
|
|
|
|
* After "git checkout --detach", "git status" reported a fairly
|
|
useless "HEAD detached at HEAD", instead of saying at which exact
|
|
commit.
|
|
(merge 0eb8548 mm/detach-at-HEAD-reflog later to maint).
|
|
|
|
* When "git send-email" wanted to talk over Net::SMTP::SSL,
|
|
Net::Cmd::datasend() did not like to be fed too many bytes at the
|
|
same time and failed to send messages. Send the payload one line
|
|
at a time to work around the problem.
|
|
(merge f60c483 sa/send-email-smtp-batch-data-limit later to maint).
|
|
|
|
* When "git am" was rewritten as a built-in, it stopped paying
|
|
attention to user.signingkey, which was fixed.
|
|
(merge 434c64d pt/am-builtin later to maint).
|
|
|
|
* It was not possible to use a repository-lookalike created by "git
|
|
worktree add" as a local source of "git clone".
|
|
(merge d78db84 nd/clone-linked-checkout later to maint).
|
|
|
|
* On a case insensitive filesystems, setting GIT_WORK_TREE variable
|
|
using a random cases that does not agree with what the filesystem
|
|
thinks confused Git that it wasn't inside the working tree.
|
|
(merge 63ec5e1 js/icase-wt-detection later to maint).
|
|
|
|
* Performance-measurement tests did not work without an installed Git.
|
|
(merge 31cd128 sb/perf-without-installed-git later to maint).
|
|
|
|
* A test script for the HTTP service had a timing dependent bug,
|
|
which was fixed.
|
|
(merge 362d8b6 sb/http-flaky-test-fix later to maint).
|
|
|
|
* There were some classes of errors that "git fsck" diagnosed to its
|
|
standard error that did not cause it to exit with non-zero status.
|
|
(merge 122f76f jc/fsck-dropped-errors later to maint).
|
|
|
|
* Work around "git p4" failing when the P4 depot records the contents
|
|
in UTF-16 without UTF-16 BOM.
|
|
(merge 1f5f390 ls/p4-translation-failure later to maint).
|
|
|
|
* When "git gc --auto" is backgrounded, its diagnosis message is
|
|
lost. Save it to a file in $GIT_DIR and show it next time the "gc
|
|
--auto" is run.
|
|
(merge 329e6e8 nd/gc-auto-background-fix later to maint).
|
|
|
|
* The submodule code has been taught to work better with separate
|
|
work trees created via "git worktree add".
|
|
(merge 11f9dd7 mk/submodule-gitdir-path later to maint).
|
|
|
|
* Code clean-up and minor fixes.
|
|
(merge 15ed07d jc/rerere later to maint).
|
|
(merge b744767 pt/pull-builtin later to maint).
|
|
(merge 29bc480 nd/ls-remote-does-not-have-u-option later to maint).
|
|
(merge be510e0 jk/asciidoctor-section-heading-markup-fix later to maint).
|
|
(merge 83e6bda tk/typofix-connect-unknown-proto-error later to maint).
|
|
(merge a43eb67 tk/doc-interpret-trailers-grammo later to maint).
|
|
(merge ba128e2 es/worktree-add-cleanup later to maint).
|
|
(merge 44cd91e cc/quote-comments later to maint).
