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. Git 2.29.2 has been tagged. About 30+ topics are in 'next' waiting their turns to graduate to 'master', while a handful more of topics in 'seen' are marked to graduate to 'next'. Since it's been a while since I sent out the "A note from the maintainer" message the last time, I'll send out one shortly. Copies of the source code to Git live in many repositories, and the following is a list of the ones I push into. 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/ 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] * jk/sideband-more-error-checking (2020-10-29) 1 commit - sideband: diagnose more sideband anomalies (this branch uses js/avoid-split-sideband-message.) The code to detect premature EOF in the sideband demultiplexer has been cleaned up. Will merge to 'next'. * js/default-branch-name-adjust-t5411 (2020-10-28) 4 commits - t5411: finish preparing for `main` being the default branch name - t5411: adjust the remaining support files for init.defaultBranch=main - t5411: start adjusting the support files for init.defaultBranch=main - t5411: start using the default branch name "main" (this branch uses js/default-branch-name-part-4-minus-1.) Prepare a test script to transition of the default branch name to 'main'. Other than a minor nit, overall it looked sensible. cf. <xmqq5z6u9kkv.fsf@xxxxxxxxxxxxxxxxxxxxxx> -------------------------------------------------- [Stalled] * hn/reftable (2020-10-01) 13 commits . reftable: "test-tool dump-reftable" command. . reftable: rest of library . reftable: file level tests . reftable: read reftable files . reftable: write reftable files . reftable: a generic binary tree implementation . reftable: reading/writing blocks . reftable: (de)serialization for the polymorphic record type. . reftable: utility functions . reftable: add a barebones unittest framework . vcxproj: adjust for the reftable changes . reftable: define the public API . reftable: add LICENSE The reftable backend for the refs API.

Expecting a reroll. The intent is very good. * bc/rev-parse-path-format (2020-10-09) 2 commits - rev-parse: add option for absolute or relative path formatting - abspath: add a function to resolve paths with missing components "git rev-parse" can be explicitly told to give output as absolute or relative path. * ar/fetch-transfer-ipversion (2020-09-16) 1 commit - config: option transfer.ipversion to set transport protocol version for network fetches Adds transfer.ipversion configuration variable.

On hold for now. * dr/push-remoteref-fix (2020-04-23) 1 commit - remote.c: fix handling of %(push:remoteref) The "%(push:remoteref)" placeholder in the "--format=" argument of "git format-patch" (and friends) only showed what got explicitly configured, not what ref at the receiving end would be updated when "git push" was used, as it ignored the default behaviour (e.g. update the same ref as the source). Discard for now. cf. <xmqqv9gu7c61.fsf@xxxxxxxxxxxxxxxxxxxxxx> cf. <20200911214358.acl3hy2e763begoo@feanor> * mk/use-size-t-in-zlib (2018-10-15) 1 commit - zlib.c: use size_t for size The wrapper to call into zlib followed our long tradition to use "unsigned long" for sizes of regions in memory, which have been updated to use "size_t". -------------------------------------------------- [Cooking] * cm/t7xxx-cleanup (2020-10-22) 6 commits (merged to 'next' on 2020-10-26 at 8b58e54942) + t7102: prepare expected output inside test_expect_* block + t7201: put each command on a separate line + t7201: use 'git -C' to avoid subshell + t7102,t7201: remove whitespace after redirect operator + t7102,t7201: remove unnecessary blank spaces in test body + t7101,t7102,t7201: modernize test formatting Originally merged to 'next' on 2020-10-23 Micro clean-up. Will merge to 'master'. * js/avoid-split-sideband-message (2020-10-27) 3 commits (merged to 'next' on 2020-10-27 at 06b2f75522) + test-pkt-line: drop colon from sideband identity (merged to 'next' on 2020-10-26 at 1b550f3245) + sideband: report unhandled incomplete sideband messages as bugs + sideband: avoid reporting incomplete sideband messages (this branch is used by jk/sideband-more-error-checking.) The side-band status report can be sent at the same time as the primary payload multiplexed, but the demultiplexer on the receiving end incorrectly split a single status report into two, which has been corrected. Will merge to 'master'. * jt/apply-reverse-twice (2020-10-20) 1 commit (merged to 'next' on 2020-10-26 at f060893eb7) + apply: when -R, also reverse list of sections "git apply -R" did not handle patches that touch the same path twice correctly, which has been corrected. This is most relevant in a patch that changes a path from a regular file to a symbolic link (and vice versa). Will merge to 'master'. * av/fsmonitor-cleanup (2020-10-21) 2 commits - fsmonitor: make output of test-dump-fsmonitor more concise - fsmonitor: stop inline'ing mark_fsmonitor_valid / _invalid Code clean-up. Unneeded?

Will merge to 'master'. * jc/sequencer-stopped-sha-simplify (2020-10-21) 1 commit - sequencer: tolerate abbreviated stopped-sha file Recently the format of an internal state file "rebase -i" uses has been tightened up for consistency, which would hurt those who start "rebase -i" with old git and then continue with new git. Loosen the reader side a bit (which we may want to tighten again in a year or so). Is this a real issue, or just a theoretical one? Perhaps drop? cf. <xmqqd01b429a.fsf@xxxxxxxxxxxxxxxxxxxxxx> * jk/perl-warning (2020-10-21) 1 commit (merged to 'next' on 2020-10-28 at 5fcb98f2ff) + perl: check for perl warnings while running tests Dev support.

Adjust tests so that they won't scream when the default initial branch name is changed to 'main'.

Will merge to 'master'. * pb/ref-filter-with-crlf (2020-10-29) 2 commits - log, show: add tests for messages containing CRLF - ref-filter: handle CRLF at end-of-line more gracefully A commit and tag object may have CR at the end of each and every line (you can create such an object with hash-object or using --cleanup=verbatim to decline the default clean-up action), but it would make it impossible to have a blank line to separate the title from the body of the message. Be lenient and accept a line with lone CR on it as a blank line, too. Will merge to 'next'. * ve/userdiff-bash (2020-10-22) 1 commit (merged to 'next' on 2020-10-26 at 2b34be98fe) + userdiff: support Bash The userdiff pattern learned to identify the function definition in POSIX shells and bash. Will merge to 'master'. * ab/git-remote-exit-code (2020-10-27) 1 commit - remote: add meaningful exit code on missing/existing Exit codes from "git remote add" etc. were not usable by scripted callers.

Looking good. * en/merge-tests (2020-10-26) 9 commits - t6423: add more details about direct resolution of directories - t6423: note improved ort handling with untracked files - t6423, t6436: note improved ort handling with dirty files - merge tests: expect slight differences in output for recursive vs. ort - t6423: expect improved conflict markers labels in the ort backend - t6404, t6423: expect improved rename/delete handling in ort backend - t6416: correct expectation for rename/rename(1to2) + directory/file - merge tests: expect improved directory/file conflict handling in ort - t/: new helper for tests that pass with ort but fail with recursive (this branch uses en/dir-rename-tests.)

Will merge to 'next'. * sj/untracked-files-in-submodule-directory-is-not-dirty (2020-10-26) 1 commit - diff: do not show submodule with untracked files as "-dirty" "git diff" showed a submodule working tree with untracked cruft as "Submodule commit <objectname>-dirty", but a natural expectation is that the "-dirty" indicator would align with "git describe --dirty", which does not consider having untracked files in the working tree as source of dirtiness. The inconsistency has been fixed. Needs doc update. * fc/zsh-completion (2020-10-28) 29 commits - zsh: update copyright notices - completion: bash: remove old compat wrappers - completion: bash: cleanup cygwin check - completion: bash: trivial cleanup - completion: zsh: add simple version check - completion: zsh: trivial simplification - completion: zsh: add alias descriptions - completion: zsh: improve command tags - completion: zsh: refactor command completion - completion: zsh: shuffle functions around - completion: zsh: simplify file_direct - completion: zsh: simplify nl_append - completion: zsh: trivial cleanup - completion: zsh: simplify direct compadd - completion: zsh: simplify compadd functions - completion: zsh: fix splitting of words - completion: zsh: add missing direct_append - completion: fix conflict with bashcomp - completion: zsh: fix completion for --no-.. options - completion: bash: remove zsh wrapper - completion: bash: synchronize zsh wrapper - completion: zsh: fix for command aliasing - completion: prompt: fix color for Zsh - completion: zsh: update slave script locations - completion: zsh: fix for directories with spaces - completion: zsh: reorganize install instructions - completion: zsh: fix bash script extension - completion: zsh: fix name due to broken autoloading - completion: zsh: fix __gitcomp_direct() Zsh autocompletion (in contrib/) update.

Will merge to 'master'. * ds/maintenance-commit-graph-auto-fix (2020-10-12) 2 commits (merged to 'next' on 2020-10-26 at 429d1371d8) + maintenance: core.commitGraph=false prevents writes + maintenance: test commit-graph auto condition Test-coverage enhancement of running commit-graph task "git maintenance" as needed led to discovery and fix of a bug. Will merge to 'master'. * ss/submodule-add-in-c (2020-10-07) 3 commits - t7400: add test to check 'submodule add' for tracked paths - submodule: port submodule subcommand 'add' from shell to C - dir: change the scope of function 'directory_exists_in_index()' "git submodule add" being rewritten in C. * ak/corrected-commit-date (2020-10-08) 10 commits - doc: add corrected commit date info - commit-reach: use corrected commit dates in paint_down_to_common() - commit-graph: use generation v2 only if entire chain does - commit-graph: implement generation data chunk - commit-graph: implement corrected commit date - commit-graph: add a slab to store topological levels - commit-graph: return 64-bit generation number - commit-graph: consolidate fill_commit_graph_info - revision: parse parent in indegree_walk_step() - commit-graph: fix regression when computing Bloom filters The commit-graph learned to use corrected commit dates instead of the generation number to help topological revision traversal. Almost there. cf. <685afed6-f01f-5d22-80d4-00fdc11caf0a@xxxxxxxxx> * mk/diff-ignore-regex (2020-10-20) 2 commits (merged to 'next' on 2020-10-26 at c68727da93) + diff: add -I<regex> that ignores matching changes + merge-base, xdiff: zero out xpparam_t structures "git diff" family of commands learned the "-I<regex>" option to ignore hunks whose changed lines all match the given pattern. Will merge to 'master'. * mt/parallel-checkout-part-1 (2020-10-29) 19 commits - ci: run test round with parallel-checkout enabled - parallel-checkout: add tests related to .gitattributes - parallel-checkout: add tests related to clone collisions - parallel-checkout: add tests for basic operations - checkout-index: add parallel checkout support - builtin/checkout.c: complete parallel checkout support - make_transient_cache_entry(): optionally alloc from mem_pool - parallel-checkout: support progress displaying - parallel-checkout: make it truly parallel - unpack-trees: add basic support for parallel checkout - entry: add checkout_entry_ca() which takes preloaded conv_attrs - entry: move conv_attrs lookup up to checkout_entry() - entry: extract cache_entry update from write_entry() - entry: make fstat_output() and read_blob_entry() public - entry: extract a header file for entry.c functions - convert: add conv_attrs classification - convert: add get_stream_filter_ca() variant - convert: add [async_]convert_to_working_tree_ca() variants - convert: make convert_attrs() and convert structs public (this branch uses jk/checkout-index-errors.) Parallel checkout. * dl/diff-merge-base (2020-09-21) 10 commits (merged to 'next' on 2020-10-26 at 114d94030b) + contrib/completion: complete `git diff --merge-base` + builtin/diff-tree: learn --merge-base + builtin/diff-index: learn --merge-base + t4068: add --merge-base tests + diff-lib: define diff_get_merge_base() + diff-lib: accept option flags in run_diff_index() + contrib/completion: extract common diff/difftool options + git-diff.txt: backtick quote command text + git-diff-index.txt: make --cached description a proper sentence + t4068: remove unnecessary >tmp "git diff A...B" learned "git diff --merge-base A B", which is a longer short-hand to say the same thing. Will merge to 'master'. * ds/maintenance-part-3 (2020-10-16) 8 commits - maintenance: add troubleshooting guide to docs - maintenance: use 'incremental' strategy by default - maintenance: create maintenance.strategy config - maintenance: add start/stop subcommands - maintenance: add [un]register subcommands - for-each-repo: run subcommands on configured repos - maintenance: add --schedule option and config - maintenance: optionally skip --auto process Parts of "git maintenance" to ease writing crontab entries (and other scheduling system configuration) for it. * es/config-hooks (2020-10-16) 8 commits - hook: replace find_hook() with hook_exists() - hook: add 'run' subcommand - parse-options: parse into strvec - hook: implement hookcmd.<name>.skip - hook: include hookdir hook in list - hook: add list command - hook: scaffolding for git-hook subcommand - doc: propose hooks managed by the config The "hooks defined in config" topic. * mt/grep-sparse-checkout (2020-09-10) 9 commits - config: add setting to ignore sparsity patterns in some cmds - grep: honor sparse checkout patterns - config: correctly read worktree configs in submodules - config: make do_git_config_sequence receive a 'struct repository' - t/helper/test-config: unify exit labels - t/helper/test-config: diagnose missing arguments - t/helper/test-config: be consistent with exit codes - t1308-config-set: avoid false positives when using test-config - doc: grep: unify info on configuration variables "git grep" has been tweaked to be limited to the sparse checkout paths.
