Subject: What's cooking in git.git (Mar 2021, #02; Mon, 8)

From: Junio C Hamano <[email-masked]>
Date: Mon, 08 Mar 2021 15:54:41 -0800

Here are the topics that have been cooking.  Commits prefixed with '-' are
only in 'seen' (formerly 'pu'---proposed updates) while commits prefixed
with '+' are in 'next'.  The ones marked with '.' do not appear in any of
the integration branches, but I am still holding onto them.

The second release candidate Git v2.31.0-rc2 will be tagged tomorrow.

Copies of the source code to Git live in many repositories, and the
following is a list of the ones I push into or their mirrors.  Some
repositories have only a subset of branches.

With maint, master, next, seen, todo:

	git://git.kernel.org/pub/scm/git/git.git/
	git://repo.or.cz/alt-git.git/
	https://kernel.googlesource.com/pub/scm/git/git/
	https://github.com/git/git/
	https://gitlab.com/git-vcs/git/

With all the integration branches and topics broken out:

	https://github.com/gitster/git/

Even though the preformatted documentation in HTML and man format
are not sources, they are published in these repositories for
convenience (replace "htmldocs" with "manpages" for the manual
pages):

	git://git.kernel.org/pub/scm/git/git-htmldocs.git/
	https://github.com/gitster/git-htmldocs.git/

Release tarballs are available at:

* jk/open-returns-eintr (2021-03-01) 2 commits
  (merged to 'next' on 2021-03-02 at 7f0218e627)
 + config.mak.uname: enable OPEN_RETURNS_EINTR for macOS Big Sur
 + Makefile: add OPEN_RETURNS_EINTR knob

 Work around platforms whose open() is reported to return EINTR (it
 shouldn't, as we do our signals with SA_RESTART).

--------------------------------------------------
[New Topics]

* ab/make-cocci-dedup (2021-03-05) 4 commits

  (merged to 'next' on 2021-03-07 at c79f295216)
 + fetch-pack: do not mix --pack_header and packfile uri

 The code to fsck objects received across multiple packs during a
 single git fetch session has been broken when the packfile URI
 feature was in use.  A workaround has been added by disabling the
 codepath to avoid keeping a packfile that is too small.

 Will merge to 'master'.

* jk/symlinked-dotgitx-files (2020-10-23) 9 commits
 - docs: document symlink restrictions for .git* files
 - fsck: complain when .gitattributes or .gitignore is a symlink
 - verify_path(): disallow symlinks in .gitattributes and .gitignore

 - t7450: test verify_path() handling of gitmodules
 - t7415: rename to expand scope
 - fsck_tree(): wrap some long lines
 - fsck_tree(): fix shadowed variable

 "git fsck" and the corresponding check done during the transport
 learned to ensure that in-tree files like `.gitignore` and
 `.gitattributes` are not symbolic links.

 It seems that there are real projects with .gitignore recorded as
 symlinks, which may need to loosen the fsck setting.  Do we need to
 introduce a class that is separate from symlinked .gitmodules that
 has potential consequences that is more/less grave, so that these
 projects can opt out of the new checks?

* ab/remote-write-config-in-camel-case (2021-02-24) 2 commits
  (merged to 'next' on 2021-03-01 at a01bd0d8e4)
 + remote: write camel-cased *.pushRemote on rename

 canonical camelCase.

  (merged to 'next' on 2021-03-01 at 926537ea97)

 A new configuration variable has been introduced to allow choosing
 which version of the generation number gets used in the
 commit-graph file.

* mt/cleanly-die-upon-missing-required-filter (2021-02-26) 1 commit
  (merged to 'next' on 2021-03-01 at 357954af7c)
 + convert: fail gracefully upon missing clean cmd on required filter

 We had a code to diagnose and die cleanly when a required
 clean/smudge filter is missing, but an assert before that
 unnecessarily fired, hiding the end-user facing die() message.

 Will cook in 'next'.

 Reorganize Makefile to allow building git.o and other essential
 objects without extra stuff needed only for testing.

 The last step is of dubious value, but otherwise looked OK.

 - builtin/multi-pack-index.c: don't handle 'progress' separately
 - builtin/multi-pack-index.c: inline 'flags' with options
 - Merge branch 'ds/chunked-file-api' into tb/reverse-midx

 An on-disk reverse-index to map the in-pack location of an object

 available.

 Needs review.

* cm/rebase-i-fixup-amend-reword (2021-03-01) 6 commits
 - doc/git-commit: add documentation for fixup=[amend|reword] options
 - t3437: use --fixup with options to create amend! commit
 - t7500: add tests for --fixup=[amend|reword] options
 - commit: add a reword suboption to --fixup
 - commit: add amend suboption to --fixup to create amend! commit
 - sequencer: export subject_length()
 (this branch uses cm/rebase-i and cm/rebase-i-updates.)

 "git commit --fixup=<commit>", which was to tweak the changes made
 to the contents while keeping the original log message intact,
 learned "--fixup=(amend|reword):<commit>", that can be used to
 tweak both the message and the contents, and only the message,
 respectively.

 Getting there.

* jk/open-dotgitx-with-nofollow (2021-02-16) 6 commits
  (merged to 'next' on 2021-02-25 at a784bf7be6)
 + mailmap: do not respect symlinks for in-tree .mailmap
 + exclude: do not respect symlinks for in-tree .gitignore
 + attr: do not respect symlinks for in-tree .gitattributes
 + exclude: add flags parameter to add_patterns()
 + attr: convert "macro_ok" into a flags field
 + add open_nofollow() helper

 It does not make sense to make ".gitattributes", ".gitignore" and
 ".mailmap" symlinks, as they are supposed to be usable from the
 object store (think: bare repositories where HEAD:.mailmap etc. are
 used).  When these files are symbolic links, we used to read the
 contents of the files pointed by them by mistake, which has been
 corrected.

 + packfile: introduce 'find_kept_pack_entry()'

 "git repack" so far has been only capable of repacking everything
 under the sun into a single pack (or split by size).  A cleverer
 strategy to reduce the cost of repacking a repository has been
 introduced.
