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. The seventh batch of topics in this round are now in 'master'. We'll start stabilizing early next month, aiming for 2.33 final hopefully by mid-August. 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/ -------------------------------------------------- [Graduated to 'master'] * ab/attribute-format (2021-07-13) 5 commits (merged to 'next' on 2021-07-20 at 44e5606a6e) + advice.h: add missing __attribute__((format)) & fix usage + *.h: add a few missing __attribute__((format)) + *.c static functions: add missing __attribute__((format)) + sequencer.c: move static function to avoid forward decl + *.c static functions: don't forward-declare __attribute__ Many "printf"-like helper functions we have have been annotated with __attribute__() to catch placeholder/parameter mismatches. * ab/pkt-line-tests (2021-07-19) 1 commit (merged to 'next' on 2021-07-20 at 8e5e53450c) + test-lib-functions: use test-tool for [de]packetize() Tests that cover protocol bits have been updated and helpers used there have been consolidated. * dl/diff-merge-base (2021-07-12) 1 commit (merged to 'next' on 2021-07-20 at 013d013bcf) + git-diff: fix missing --merge-base docs "git diff --merge-base" documentation has been updated. * dl/packet-read-response-end-fix (2021-07-09) 1 commit (merged to 'next' on 2021-07-16 at 6a7734b6b5) + pkt-line: replace "stateless separator" with "response end" Error message update. * ds/gender-neutral-doc-guidelines (2021-07-16) 1 commit (merged to 'next' on 2021-07-20 at 06d325e064) + CodingGuidelines: recommend gender-neutral description A guideline for gender neutral documentation has been added. * ds/status-with-sparse-index (2021-07-14) 16 commits (merged to 'next' on 2021-07-20 at 1558d36c0f) + t1092: document bad sparse-checkout behavior + fsmonitor: integrate with sparse index + wt-status: expand added sparse directory entries + status: use sparse-index throughout + status: skip sparse-checkout percentage with sparse-index + diff-lib: handle index diffs with sparse dirs + dir.c: accept a directory as part of cone-mode patterns + unpack-trees: unpack sparse directory entries + unpack-trees: rename unpack_nondirectories() + unpack-trees: compare sparse directories correctly + unpack-trees: preserve cache_bottom + t1092: add tests for status/add and sparse files + t1092: expand repository data shape + t1092: replace incorrect 'echo' with 'cat' + sparse-index: include EXTENDED flag when expanding + sparse-index: skip indexes with unmerged entries (this branch is used by ds/add-with-sparse-index and ds/commit-and-checkout-with-sparse-index.) "git status" codepath learned to work with sparsely populated index without hydrating it fully. * en/rename-limits-doc (2021-07-15) 4 commits (merged to 'next' on 2021-07-20 at a89253d530) + rename: bump limit defaults yet again + diffcore-rename: treat a rename_limit of 0 as unlimited + doc: clarify documentation for rename/copy limits + diff: correct warning message when renameLimit exceeded Documentation on "git diff -l<n>" and diff.renameLimit have been updated, and the defaults for these limits have been raised. * ew/many-alternate-optim (2021-07-07) 5 commits (merged to 'next' on 2021-07-16 at a2d8bc731d) + oidtree: a crit-bit tree for odb_loose_cache + oidcpy_with_padding: constify `src' arg + make object_directory.loose_objects_subdir_seen a bitmap + avoid strlen via strbuf_addstr in link_alt_odb_entry + speed up alt_odb_usable() with many alternates Optimization for repositories with many alternate object store. * hj/commit-allow-empty-message (2021-07-09) 2 commits (merged to 'next' on 2021-07-16 at 86b79d3010) + commit: remove irrelavent prompt on `--allow-empty-message` + commit: reorganise commit hint strings "git commit --allow-empty-message" won't abort the operation upon an empty message, but the hint shown in the editor said otherwise. * hn/refs-debug-empty-prefix (2021-07-19) 1 commit (merged to 'next' on 2021-07-20 at 2772d3efb2) + refs/debug: quote prefix Debugging aid. * jk/log-decorate-optim (2021-07-14) 7 commits (merged to 'next' on 2021-07-16 at 5637878b90) + load_ref_decorations(): fix decoration with tags (merged to 'next' on 2021-07-08 at a3b6f978ab) + add_ref_decoration(): rename s/type/deco_type/ + load_ref_decorations(): avoid parsing non-tag objects + object.h: add lookup_object_by_type() function + object.h: expand docstring for lookup_unknown_object() + log: avoid loading decorations for userformats that don't need it + pretty.h: update and expand docstring for userformat_find_requirements() Optimize "git log" for cases where we wasted cycles to load ref decoration data that may not be needed. * jk/t0000-subtests-fix (2021-07-19) 1 commit (merged to 'next' on 2021-07-20 at 81412e1684) + t0000: clear GIT_SKIP_TESTS before running sub-tests (this branch is used by ab/lib-subtest and ps/t0000-output-directory-fix.) Test fix. * js/ci-make-sparse (2021-07-26) 3 commits (merged to 'next' on 2021-07-26 at 689316a459) + ci/install-dependencies: handle "sparse" job package installs + ci: run "apt-get update" before "apt-get install" (merged to 'next' on 2021-07-20 at 99f518bdef) + ci: run `make sparse` as part of the GitHub workflow The CI gained a new job to run "make sparse" check. * pb/dont-complete-aliased-options (2021-07-16) 1 commit (merged to 'next' on 2021-07-20 at bbc531c710) + parse-options: don't complete option aliases by default The completion support used to offer alternate spelling of options that exist only for compatibility, which has been corrected. * ps/t0000-output-directory-fix (2021-07-20) 1 commit (merged to 'next' on 2021-07-20 at 7e0b7c1f0c) + t0000: fix test if run with TEST_OUTPUT_DIRECTORY (this branch is used by ab/lib-subtest; uses jk/t0000-subtests-fix.) "TEST_OUTPUT_DIRECTORY=there make test" failed to work, which has been corrected. * sm/worktree-add-lock (2021-07-15) 3 commits (merged to 'next' on 2021-07-16 at 609c0a4944) + worktree: teach `add` to accept --reason <string> with --lock + worktree: mark lock strings with `_()` for translation + t2400: clean up '"add" worktree with lock' test "git worktree add --lock" learned to record why the worktree is locked with a custom message. * tb/reverse-midx (2021-07-19) 1 commit (merged to 'next' on 2021-07-20 at 995cb54b5b) + multi-pack-index: fix potential segfault without sub-command The code that gives an error message in "git multi-pack-index" when no subcommand is given tried to print a NULL pointer as a strong, which has been corrected. -------------------------------------------------- [New Topics] * jc/bisect-sans-show-branch (2021-07-28) 2 commits - bisect: simplify return code from bisect_checkout() - bisect: do not run show-branch just to show the current commit "git bisect" spawned "git show-branch" only to pretty-print the title of the commit after checking out the next version to be tested; this has been rewritten in C. Will merge to '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". Needs review and design discussion. As I wrote in the log message, I suspect that this may belong to one layer higher, i.e. at ll_merge() before it dispatches to type specific drivers. * os/bisect-runs-show-branch-without-pager (2021-07-27) 1 commit - bisect: disable pager while invoking show-branch When "git bisect" spawns "git show-branch" to pretty-print the title of the commit to be tested, it could have invoked user's pager if user configured to run pager while running show-branch. The invocation of show-branch has been changed to disable pager, even if one is configured. Will discard. This probably is unnecessary with the rewrite to get rid of the show-branch invocation altogether. * hn/refs-test-cleanup-contd (2021-07-22) 11 commits (merged to 'next' on 2021-07-28 at dd3af04939) + t6001: avoid direct file system access + t6500: use "ls -1" to snapshot ref database state + t7064: use update-ref -d to remove upstream branch + t1410: mark test as REFFILES + t1405: mark test for 'git pack-refs' as REFFILES + t1405: use 'git reflog exists' to check reflog existence (merged to 'next' on 2021-07-22 at 2ab8bc259a) + t2402: use ref-store test helper to create broken symlink + t3320: use git-symbolic-ref rather than filesystem access + t6120: use git-update-ref rather than filesystem access + t1503: mark symlink test as REFFILES + t6050: use git-update-ref rather than filesystem access -------------------------------------------------- [Stalled] * 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.

"git add" can work better with the sparse index. * fc/pull-no-rebase-merges-theirs-into-ours (2021-07-21) 1 commit (merged to 'next' on 2021-07-28 at f8e6567082) + doc: pull: fix rebase=false documentation Documentation fix for "git pull --rebase=no".

Will merge to 'next'. * ar/submodule-add-config (2021-07-28) 1 commit - submodule--helper: introduce add-config subcommand (this branch uses ar/submodule-add.)

It is clear that a problem exists, but it is unclear if the proposed solution is a desirable one. * ab/bundle-tests (2021-07-22) 2 commits (merged to 'next' on 2021-07-22 at 053b5d0ecf) + bundle tests: use test_cmp instead of grep + bundle tests: use ">file" not ": >file" "git bundle" gained more test coverage.

The series tries to fix them up. * bc/inactive-submodules (2021-07-02) 1 commit - submodule: mark submodules with update=none as inactive Usability update for inactive submodules. Under review. cf. <fc5ec100-1d42-4199-236e-7a99c9218f38@xxxxxxxxx> cf. <bf1893ee-6973-d8b2-659e-bb239a0a9ae2@xxxxxxxxx> * en/ort-perf-batch-14 (2021-07-20) 7 commits - merge-ort: restart merge with cached renames to reduce process entry cost - merge-ort: avoid recursing into directories when we don't need to - merge-ort: defer recursing into directories when merge base is matched - merge-ort: add a handle_deferred_entries() helper function - merge-ort: add data structures for allowable trivial directory resolves - merge-ort: add some more explanations in collect_merge_info_callback() - merge-ort: resolve paths early when we have sufficient information (this branch is used by en/ort-perf-batch-15.)
