Here are the topics that have been cooking in my tree. Commits prefixed with '+' are in 'next' (being in 'next' is a sign that a topic is stable enough to be used and are candidate to be in a future release). Commits prefixed with '-' are only in 'seen', which means nothing more than that I have found them of interest for some reason (like "it may have hard-to-resolve conflicts with another topic already in flight" or "this may turn out to be useful"). Do not read too much into a topic being in (or not in) 'seen'. The ones marked with '.' do not appear in any of the integration branches, but I am still holding onto them. Git 2.33-rc2 will be tagged tomorrow, with a few build and regression fixes (not in 'master' yet as of this writing). 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: https://www.kernel.org/pub/software/scm/git/ -------------------------------------------------- [New Topics] * cb/builtin-merge-format-string-fix (2021-08-09) 1 commit - builtin/merge: avoid -Wformat-extra-args from ancient Xcode Code clean-up. Will merge to 'next'. * cb/many-alternate-optim-fixup (2021-08-09) 2 commits (merged to 'next' on 2021-08-09 at 3572bef349) + object-store: avoid extra ';' from KHASH_INIT + oidtree: avoid nested struct oidtree_node (this branch is used by cb/ci-build-pedantic.) Build fix. Will merge to 'master'. * ka/want-ref-in-namespace (2021-08-09) 3 commits - docs: clarify the interaction of transfer.hideRefs and namespaces - upload-pack.c: treat want-ref relative to namespace - t5730: introduce fetch command helper "git upload-pack" which runs on the other side of "git fetch" forgot to take the ref namespaces into account when handling want-ref requests. * np/blame-ignore-revs-file-may-be-optional (2021-08-09) 1 commit - blame: add config `blame.ignoreRevsFileIsOptional` When the file named by blame.ignoreRevsFile configuration variable does not exist, it causes "git blame" to die. Sometimes, it is useful if the files named by configuration variables can be made optional (it would allow ~/.gitconfig to give a filename, and make it effective only in repositories that have a file with that name). This uses an extra variable that marks that the variable is optional. Yet another alternative is being discussed to define syntax for "optional" filename values, so that the same mechanism can be used for not just blame.ignoreRevsFile but other filenames. Queued just as a reminder of the theme. * cb/ci-build-pedantic (2021-08-09) 1 commit - ci: run a pedantic build as part of the GitHub workflow (this branch uses cb/many-alternate-optim-fixup.) CI update. Will merge to 'next'. * jn/log-m-does-not-imply-p (2021-08-09) 1 commit (merged to 'next' on 2021-08-09 at d937d09924) + Revert 'diff-merges: let "-m" imply "-p"' Earlier "git log -m" was changed to always produce patch output, which would break existing scripts, which has been reverted. Will merge to 'master'. * ds/sparse-index-ignored-files (2021-08-10) 9 commits - sparse-checkout: clear tracked sparse dirs - sparse-index: add SPARSE_INDEX_IGNORE_CONFIG flag - attr: be careful about sparse directories - sparse-checkout: create helper methods - unpack-trees: fix nested sparse-dir search - sparse-index: silently return when cache tree fails - sparse-index: silently return when not using cone-mode patterns - t7519: rewrite sparse index test - Merge branch 'ds/add-with-sparse-index' into ds/sparse-index-ignored-files (this branch uses ds/add-with-sparse-index.) In cone mode, the sparse-index codepath learned to remove ignored files (like build artifacts) outside the sparse cone, allowing the entire directory outside the sparse cone to be removed, which is especially useful when the sparse patterns change. * jc/userdiff-pattern-hint (2021-08-10) 1 commit - userdiff: comment on the builtin patterns Remind developers that the userdiff patterns should be kept simple and permissive, assuming that the contents they apply are always syntactically correct. * jk/apply-binary-hunk-parsing-fix (2021-08-10) 1 commit - apply: keep buffer/size pair in sync when parsing binary hunks "git apply" miscounted the bytes and failed to read to the end of binary hunks.

Will merge to 'next'. * js/advise-when-skipping-cherry-picked (2021-08-10) 2 commits - SQUASH??? - sequencer: advise if skipping cherry-picked commit "git rebase" by default skips changes that are equivalent to commits that are already in the history the branch is rebased onto; give messages when this happens to let the users be aware of skipped commits, and also teach them how to tell "rebase" to keep duplicated changes. * jt/grep-wo-submodule-odb-as-alternate (2021-08-10) 7 commits - t7814: show lack of alternate ODB-adding - grep: add repository to OID grep sources - grep: allocate subrepos on heap - grep: read submodule entry with explicit repo - grep: typesafe versions of grep_source_init - grep: use submodule-ODB-as-alternate lazy-addition - submodule: lazily add submodule ODBs as alternates The code to make "git grep" recurse into submodules has been updated to migrate away from the "add submodule's object store as an alternate object store" mechanism (which is suboptimal). -------------------------------------------------- [Stalled] * gh/gitweb-branch-sort (2021-06-10) 1 commit - gitweb: use HEAD as secondary sort key in git_get_heads_list() Tie-break branches that point at the same object in the list of branches on GitWeb to show the one pointed at by HEAD early. Waiting for reviews. * lh/systemd-timers (2021-07-02) 3 commits - maintenance: add support for systemd timers on Linux - maintenance: `git maintenance run` learned `--scheduler=<scheduler>` - cache.h: Introduce a generic "xdg_config_home_for(…)" function "git maintenance" scheduler learned to use systemd timers as a possible backend.

Waiting for reviews. * en/zdiff3 (2021-06-15) 2 commits - update documentation for new zdiff3 conflictStyle - xdiff: implement a zealous diff3, or "zdiff3" "Zealous diff3" style of merge conflict presentation has been added. Expecting a reroll. cf. <CABPp-BE7-E03+x38EK-=AE5mwwdST+d50hiiud2eY2Nsf3rM5g@xxxxxxxxxxxxxx> * ao/p4-avoid-decoding (2021-04-12) 2 commits - git-p4: do not decode data from perforce by default - git-p4: avoid decoding more data from perforce "git p4" in Python-2 days used to accept a lot more kinds of data from Perforce server as uninterrupted byte sequence, but after switching to Python-3, too many things are expected to be in UTF-8, which broke traditional use cases. Waiting for reviews. * tv/p4-fallback-encoding (2021-04-30) 1 commit - git-p4: git-p4.fallbackEncoding to specify non UTF-8 charset "git p4" learns the fallbackEncoding configuration variable to safely accept changeset descriptions that aren't written in UTF-8.

Will cook in 'next'. * jc/trivial-threeway-binary-merge (2021-07-28) 1 commit - ll-merge: teach ll_binary_merge() a trivial three-way merge The built-in merge driver for binary files learned to resolve trivial three-way merges (e.g. apply change, which turns A into B, to content A) by itself, which would help "git apply --3way" used when there is no need to use "--3way".
