Git 2.18 Release Notes |
|
====================== |
|
|
|
Updates since v2.17 |
|
------------------- |
|
|
|
UI, Workflows & Features |
|
|
|
* Rename detection logic in "diff" family that is used in "merge" has |
|
learned to guess when all of x/a, x/b and x/c have moved to z/a, |
|
z/b and z/c, it is likely that x/d added in the meantime would also |
|
want to move to z/d by taking the hint that the entire directory |
|
'x' moved to 'z'. A bug causing dirty files involved in a rename |
|
to be overwritten during merge has also been fixed as part of this |
|
work. |
|
|
|
* "git filter-branch" learned to use a different exit code to allow |
|
the callers to tell the case where there was no new commits to |
|
rewrite from other error cases. |
|
|
|
* When built with more recent cURL, GIT_SSL_VERSION can now specify |
|
"tlsv1.3" as its value. |
|
|
|
|
|
Performance, Internal Implementation, Development Support etc. |
|
|
|
* A "git fetch" from a repository with insane number of refs into a |
|
repository that is already up-to-date still wasted too many cycles |
|
making many lstat(2) calls to see if these objects at the tips |
|
exist as loose objects locally. These lstat(2) calls are optimized |
|
away by enumerating all loose objects beforehand. |
|
It is unknown if the new strategy negatively affects existing use |
|
cases, fetching into a repository with many loose objects from a |
|
repository with small number of refs. |
|
|
|
* Git can be built to use either v1 or v2 of the PCRE library, and so |
|
far, the build-time configuration USE_LIBPCRE=YesPlease instructed |
|
the build procedure to use v1, but now it means v2. USE_LIBPCRE1 |
|
and USE_LIBPCRE2 can be used to explicitly choose which version to |
|
use, as before. |
|
|
|
* The build procedure learned to optionally use symbolic links |
|
(instead of hardlinks and copies) to install "git-foo" for built-in |
|
commands, whose binaries are all identical. |
|
|
|
* Conversion from uchar[20] to struct object_id continues. |
|
|
|
* The way "git worktree prune" worked internally has been simplified, |
|
by assuming how "git worktree move" moves an existing worktree to a |
|
different place. |
|
|
|
* Code clean-up for the "repository" abstraction. |
|
(merge 00a3da2a13 nd/remove-ignore-env-field later to maint). |
|
|
|
* Code to find the length to uniquely abbreviate object names based |
|
on packfile content, which is a relatively recent addtion, has been |
|
optimized to use the same fan-out table. |
|
|
|
* The mechanism to use parse-options API to automate the command line |
|
completion continues to get extended and polished. |
|
|
|
* Copies of old scripted Porcelain commands in contrib/examples/ have |
|
been removed. |
|
|
|
* Some tests that rely on the exact hardcoded values of object names |
|
have been updated in preparation for hash function migration. |
|
|
|
* Perf-test update. |
|
|
|
* Test helper update. |
|
|
|
* The effort continues to refactor the internal global data structure |
|
to make it possible to open multiple repositories, work with and |
|
then close them, |
|
|
|
* Small test-helper programs have been consolidated into a single |
|
binary. |
|
|
|
Also contains various documentation updates and code clean-ups. |
|
|
|
|
|
Fixes since v2.17 |
|
----------------- |
|
|
|
* "git shortlog cruft" aborted with a BUG message when run outside a |
|
Git repository. The command has been taught to complain about |
|
extra and unwanted arguments on its command line instead in such a |
|
case. |
|
(merge 4aa0161e83 ma/shortlog-revparse later to maint). |
|
|
|
* "git stash push -u -- <pathspec>" gave an unnecessary and confusing |
|
error message when there was no tracked files that match the |
|
<pathspec>, which has been fixed. |
|
(merge 353278687e tg/stash-untracked-with-pathspec-fix later to maint). |
|
|
|
* "git tag --contains no-such-commit" gave a full list of options |
|
after giving an error message. |
|
(merge 3bb0923f06 ps/contains-id-error-message later to maint). |
|
|
|
* "diff-highlight" filter (in contrib/) learned to undertand "git log |
|
--graph" output better. |
|
(merge 4551fbba14 jk/diff-highlight-graph-fix later to maint). |
|
|
|
* when refs that do not point at committish are given, "git |
|
filter-branch" gave a misleading error messages. This has been |
|
corrected. |
|
(merge f78ab355e7 yk/filter-branch-non-committish-refs later to maint). |
|
|
|
* "git submodule status" misbehaved on a submodule that has been |
|
removed from the working tree. |
|
(merge 74b6bda32f rs/status-with-removed-submodule later to maint). |
|
|
|
* When credential helper exits very quickly without reading its |
|
input, it used to cause Git to die with SIGPIPE, which has been |
|
fixed. |
|
(merge a0d51e8d0e eb/cred-helper-ignore-sigpipe later to maint). |
|
|
|
* Other minor doc, test and build updates and code cleanups. |
|
(merge 248f66ed8e nd/trace-with-env later to maint). |
|
(merge 14ced5562c ys/bisect-object-id-missing-conversion-fix later to maint). |
|
(merge 5988eb631a ab/doc-hash-brokenness later to maint). |
|
(merge a4d4e32a70 pk/test-avoid-pipe-hiding-exit-status later to maint).
