Git 2.21 Release Notes |
|
====================== |
|
|
|
Backward Compatibility Notes |
|
---------------------------- |
|
|
|
|
|
Updates since v2.20 |
|
------------------- |
|
|
|
UI, Workflows & Features |
|
|
|
* The "http.version" configuration variable can be used with recent |
|
enough cURL library to force the version of HTTP used to talk when |
|
fetching and pushing. |
|
|
|
* Small fixes and features for fast-export and fast-import, mostly on |
|
the fast-export side. |
|
|
|
* "git push $there $src:$dst" rejects when $dst is not a fully |
|
qualified refname and not clear what the end user meant. The |
|
codepath has been taught to give a clearer error message, and also |
|
guess where the push should go by taking the type of the pushed |
|
object into account (e.g. a tag object would want to go under |
|
refs/tags/). |
|
|
|
* "git checkout [<tree-ish>] path..." learned to report the number of |
|
paths that have been checked out of the index or the tree-ish, |
|
which gives it the same degree of noisy-ness as the case in which |
|
the command checks out a branch. |
|
|
|
* "git quiltimport" learned "--keep-non-patch" option. |
|
|
|
* "git worktree remove" and "git worktree move" refused to work when |
|
there is a submodule involved. This has been loosened to ignore |
|
uninitialized submodules. |
|
|
|
* "git cherry-pick -m1" was forbidden when picking a non-merge |
|
commit, even though there _is_ parent number 1 for such a commit. |
|
This was done to avoid mistakes back when "cherry-pick" was about |
|
picking a single commit, but is no longer useful with "cherry-pick" |
|
that can pick a range of commits. Now the "-m$num" option is |
|
allowed when picking any commit, as long as $num names an existing |
|
parent of the commit. |
|
|
|
* Update "git multimail" from the upstream. |
|
|
|
* "git p4" update. |
|
|
|
* The "--format=<placeholder>" option of for-each-ref, branch and tag |
|
learned to show a few more traits of objects that can be learned by |
|
the object_info API. |
|
|
|
|
|
Performance, Internal Implementation, Development Support etc. |
|
|
|
* Code clean-up with optimization for the codepath that checks |
|
(non-)existence of loose objects. |
|
|
|
* More codepaths become aware of working with in-core repository |
|
instance other than the default "the_repository". |
|
|
|
* The "strncat()" function is now among the banned functions. |
|
|
|
* Portability updates for the HPE NonStop platform. |
|
|
|
* Earlier we added "-Wformat-security" to developer builds, assuming |
|
that "-Wall" (which includes "-Wformat" which in turn is required |
|
to use "-Wformat-security") is always in effect. This is not true |
|
when config.mak.autogen is in use, unfortunately. This has been |
|
fixed by unconditionally adding "-Wall" to developer builds. |
|
|
|
* The loose object cache used to optimize existence look-up has been |
|
updated. |
|
|
|
* Flaky tests can now be repeatedly run under load with the |
|
"--stress" option. |
|
(merge fb7d1e3ac8 sg/stress-test later to maint). |

|
Fixes since v2.20 |
|
----------------- |
|
|
|
* Updates for corner cases in merge-recursive. |
|
(merge cc4cb0902c en/merge-path-collision later to maint). |
|
|
|
* "git checkout frotz" (without any double-dash) avoids ambiguity by |
|
making sure 'frotz' cannot be interpreted as a revision and as a |
|
path at the same time. This safety has been updated to check also |
|
a unique remote-tracking branch 'frotz' in a remote, when dwimming |
|
to create a local branch 'frotz' out of a remote-tracking branch |
|
'frotz' from a remote. |
|
(merge be4908f103 nd/checkout-dwim-fix later to maint). |
|
|
|
* Refspecs configured with "git -c var=val clone" did not propagate |
|
to the resulting repository, which has been corrected. |
|
(merge 7eae4a3ac4 sg/clone-initial-fetch-configuration later to maint). |
|
|
|
* A properly configured username/email is required under |
|
user.useConfigOnly in order to create commits; now "git stash" |
|
(even though it creates commit objects to represent stash entries) |
|
command is exempt from the requirement. |
|
(merge 3bc2111fc2 sd/stash-wo-user-name later to maint). |
|
|
|
* The http-backend CGI process did not correctly clean up the child |
|
processes it spawns to run upload-pack etc. when it dies itself, |
|
which has been corrected. |
|
(merge 02818a98d7 mk/http-backend-kill-children-before-exit later to maint). |
|
|
|
* "git rev-list --exclude-promisor-objects" had to take an object |
|
that does not exist locally (and is lazily available) from the |
|
command line without barfing, but the code dereferenced NULL. |
|
(merge 4cf67869b2 md/list-lazy-objects-fix later to maint). |
|
|
|
* The traversal over tree objects has learned to honor |
|
":(attr:label)" pathspec match, which has been implemented only for |
|
enumerating paths on the filesystem. |
|
(merge 5a0b97b34c nd/attr-pathspec-in-tree-walk later to maint). |
|
|
|
* BSD port updates. |
|
(merge 4e3ecbd439 cb/openbsd-allows-reading-directory later to maint). |
|
(merge b6bdc2a0f5 cb/t5004-empty-tar-archive-fix later to maint). |
|
(merge 82cbc8cde2 cb/test-lint-cp-a later to maint). |
|
|
|
* Lines that begin with a certain keyword that come over the wire, as |
|
well as lines that consist only of one of these keywords, ought to |
|
be painted in color for easier eyeballing, but the latter was |
|
broken ever since the feature was introduced in 2.19, which has |
|
been corrected. |
|
(merge 1f67290450 hn/highlight-sideband-keywords later to maint). |
|
|
|
* "git log -G<regex>" looked for a hunk in the "git log -p" patch |
|
output that contained a string that matches the given pattern. |
|
Optimize this code to ignore binary files, which by default will |
|
not show any hunk that would match any pattern (unless textconv or |
|
the --text option is in effect, that is). |
|
(merge e0e7cb8080 tb/log-G-binary later to maint). |
|
|
|
* "git submodule update" ought to use a single job unless asked, but |
|
by mistake used multiple jobs, which has been fixed. |
|
(merge e3a9d1aca9 sb/submodule-fetchjobs-default-to-one later to maint). |
|
|
|
* "git stripspace" should be usable outside a git repository, but |
|
under the "-s" or "-c" mode, it didn't. |
|
(merge 957da75802 jn/stripspace-wo-repository later to maint). |
|
|
|
* Some of the documentation pages formatted incorrectly with |
|
Asciidoctor, which have been fixed. |
|
(merge b62eb1d2f4 ma/asciidoctor later to maint). |
|
|
|
* The core.worktree setting in a submodule repository should not be |
|
pointing at a directory when the submodule loses its working tree |
|
(e.g. getting deinit'ed), but the code did not properly maintain |
|
this invariant. |
|
|
|
* With zsh, "git cmd path<TAB>" was completed to "git cmd path name" |
|
when the completed path has a special character like SP in it, |
|
without any attempt to keep "path name" a single filename. This |
|
has been fixed to complete it to "git cmd path\ name" just like |
|
Bash completion does. |
|
|
|
* The test suite tried to see if it is run under bash, but the check |
|
itself failed under some other implementations of shell (notably |
|
under NetBSD). This has been corrected. |
|
(merge 54ea72f09c sg/test-bash-version-fix later to maint). |
|
|
|
* "git gc" and "git repack" did not close the open packfiles that |
|
they found unneeded before removing them, which didn't work on a |
|
platform incapable of removing an open file. This has been |
|
corrected. |
|
(merge 5bdece0d70 js/gc-repack-close-before-remove later to maint). |
|
|
|
* Code cleanup, docfix, build fix, etc. |
|
(merge 89ba9a79ae hb/t0061-dot-in-path-fix later to maint). |
|
(merge d173e799ea sb/diff-color-moved-config-option-fixup later to maint). |
