Git 2.29 Release Notes
|
|
======================
|
|
|
|
Updates since v2.28
|
|
-------------------
|
|
|
|
UI, Workflows & Features
|
|
|
|
* "git help log" has been enhanced by sharing more material from the
|
|
documentation for the underlying "git rev-list" command.
|
|
|
|
* "git for-each-ref --format=<>" learned %(contents:size).
|
|
|
|
* "git merge" learned to selectively omit " into <branch>" at the end
|
|
of the title of default merge message with merge.suppressDest
|
|
configuration.
|
|
|
|
* The component to respond to "git fetch" request is made more
|
|
configurable to selectively allow or reject object filtering
|
|
specification used for partial cloning.
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
|
|
* The changed-path Bloom filter is improved using ideas from an
|
|
independent implementation.
|
|
|
|
* Updates to the changed-paths bloom filter.
|
|
|
|
* The test framework has been updated so that most tests will run
|
|
with predictable (artificial) timestamps.
|
|
|
|
* Preliminary clean-up of the refs API in preparation for adding a
|
|
new refs backend "reftable".
|
|
|
|
* Dev support to limit the use of test_must_fail to only git commands.
|
|
|
|
* While packing many objects in a repository with a promissor remote,
|
|
lazily fetching missing objects from the promissor remote one by
|
|
one may be inefficient---the code now attempts to fetch all the
|
|
missing objects in batch (obviously this won't work for a lazy
|
|
clone that lazily fetches tree objects as you cannot even enumerate
|
|
what blobs are missing until you learn which trees are missing).
|
|
|
|
* The pretend-object mechanism checks if the given object already
|
|
exists in the object store before deciding to keep the data
|
|
in-core, but the check would have triggered lazy fetching of such
|
|
an object from a promissor remote.
|
|
|
|
* The argv_array API is useful for not just managing argv but any
|
|
"vector" (NULL-terminated array) of strings, and has seen adoption
|
|
to a certain degree. It has been renamed to "strvec" to reduce the
|
|
barrier to adoption.
|
|
|
|
* The final leg of SHA-256 transition.
|
|
|
|
* CMake support to build with MSVC for Windows bypassing the Makefile.
|
|
|
|
* A new helper function has_object() has been introduced to make it
|
|
easier to mark object existence checks that do and don't want to
|
|
trigger lazy fetches, and a few such checks are converted using it.
|
|
|
|
|
|
Fixes since v2.28
|
|
-----------------
|
|
|
|
* "git clone --separate-git-dir=$elsewhere" used to stomp on the
|
|
contents of the existing directory $elsewhere, which has been
|
|
taught to fail when $elsewhere is not an empty directory.
|
|
(merge dfaa209a79 bw/fail-cloning-into-non-empty later to maint).
|
|
|
|
* With the base fix to 2.27 regresion, any new extensions in a v0
|
|
repository would still be silently honored, which is not quite
|
|
right. Instead, complain and die loudly.
|
|
(merge ec91ffca04 jk/reject-newer-extensions-in-v0 later to maint).
|
|
|
|
* Fetching from a lazily cloned repository resulted at the server
|
|
side in attempts to lazy fetch objects that the client side has,
|
|
many of which will not be available from the third-party anyway.
|
|
(merge 77aa0941ce jt/avoid-lazy-fetching-upon-have-check later to maint).
|
|
|
|
* Fix to an ancient bug caused by an over-eager attempt for
|
|
optimization.
|
|
(merge a98f7fb366 rs/add-index-entry-optim-fix later to maint).
|
|
|
|
* Pushing a ref whose name contains non-ASCII character with the
|
|
"--force-with-lease" option did not work over smart HTTP protocol,
|
|
which has been corrected.
|
|
(merge cd85b447bf bc/push-cas-cquoted-refname later to maint).
|
|
|
|
* "git mv src dst", when src is an unmerged path, errored out
|
|
correctly but with an incorrect error message to claim that src is
|
|
not tracked, which has been clarified.
|
|
(merge 9b906af657 ct/mv-unmerged-path-error later to maint).
|
|
|
|
* Fix to a regression introduced during 2.27 cycle.
|
|
(merge cada7308ad en/fill-directory-exponential later to maint).
|
|
|
|
* Command line completion (in contrib/) update.
|
|
(merge 688b87c81b mp/complete-show-color-moved later to maint).
|
|
|
|
* All "mergy" operations that internally use the merge-recursive
|
|
machinery should honor the merge.renormalize configuration, but
|
|
many of them didn't.
|
|
|
|
* Doc cleanup around "worktree".
|
|
(merge dc9c144be5 es/worktree-doc-cleanups later to maint).
|
|
|
|
* The "git blame --first-parent" option was not documented, but now
|
|
it is.
|
|
(merge 11bc12ae1e rp/blame-first-parent-doc later to maint).
|
|
|
|
* Other code cleanup, docfix, build fix, etc.
|
|
