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 first batch of topics (all fixes, and most are meant to be merged eventually to the maintenance track) is in 'master'. The tip of the 'next' hasn't been rewound yet, so it is a good time to nominate those topics that would benefit by a chance to get rid of "oops that was wrong and here is a fix" steps out of them by rebuilding on a clean slate. 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'] * ah/make-fuzz-all-doc-update (2021-03-08) 1 commit (merged to 'next' on 2021-03-13 at e82816998f) + Makefile: update 'make fuzz-all' docs to reflect modern clang Update insn in Makefile comments to run fuzz-all target. * jc/calloc-fix (2021-03-15) 1 commit (merged to 'next' on 2021-03-18 at b656fb7750) + xcalloc: use CALLOC_ARRAY() when applicable Code clean-up. * jh/fsmonitor-prework (2021-03-17) 1 commit (merged to 'next' on 2021-03-18 at 991232bc89) + fsmonitor: avoid global-buffer-overflow READ when checking trivial response The fsmonitor interface read from its input without making sure there is something to read from.

When these files are symbolic links, we used to read the contents of the files pointed by them by mistake, which has been corrected.

Looking good. -------------------------------------------------- [Discarded] * cw/pack-vs-bigfilethreashold (2021-02-09) 2 commits . fixup! doc: mention bigFileThreshold for packing . doc: mention bigFileThreshold for packing Doc update. cw/pack-config-doc supersedes this with a bit more coverage on related knobs. * jh/simple-ipc-cleanups (2021-03-04) 9 commits - SQUASH??? - simple-ipc: update design documentation with more details - test-simple-ipc: add --token=<token> string option - test-simple-ipc: refactor command line option processing in helper - unix-stream-server: add st_dev and st_mode to socket stolen checks - simple-ipc: move error handling up a level - unix-stream-server: create unix-stream-server.c - unix-socket: simplify initialization of unix_stream_listen_opts - pkt-line: remove buffer arg from write_packetized_from_fd_no_flush() After kicking jh/simple-ipc out of 'next' and rewinding jh/simple-ipc to contain the incremental clean-up in this follow-up topic, it is no longer needed, hence retired. * es/config-hooks-part-1 (2021-02-16) 17 commits . hooks: allow callers to capture output . run-command: allow capturing of collated output . hook: provide stdin by string_list or callback . run-command: add stdin callback for parallelization . hook: allow specifying working directory for hooks . hook: allow parallel hook execution . run-command: allow stdin for run_processes_parallel . hook: support passing stdin to hooks . hook: replace find_hook() with hook_exists() . hook: add 'run' subcommand . parse-options: parse into strvec . hook: implement hookcmd.<name>.skip . hook: respect hook.runHookDir . hook: include hookdir hook in list . hook: add list command . hook: scaffolding for git-hook subcommand . doc: propose hooks managed by the config Now replaced by es/config-hooks topic. * 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 . t0060: test obscured .gitattributes and .gitignore matching . t7450: test .gitmodules symlink matching against obscured names . 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/tree-walk-with-object-type (2021-03-17) 32 commits . tree-walk.h API: add a tree_entry_extract_type() function . blame: emit a better error on 'git blame directory' . tree-walk.h API: add a get_tree_entry_path() function . tree-walk.h API: add get_tree_entry_all() . tree-walk.h API: add a tree_entry_extract_all() function . tree-entry.h API: rename tree_entry_extract() to tree_entry_extract_mode() . tree-walk.h API: document and format tree_entry_extract() . tree-walk.h API: add get_tree_entry_type() . match-trees: use "tmp" for mode in shift_tree_by() . tree-walk.h API: rename get_tree_entry() to get_tree_entry_mode() . tree-walk.h API: formatting changes for subsequent commit . tree-walk.h users: use temporary variable(s) for "mode" . fsck.c: switch on "object_type" in fsck_walk_tree() . merge-ort: correct reference to test in 62fdec17a11 . merge-tree tests: test for the mode comparison in same_entry() . tree-walk.h users: migrate miscellaneous "mode" to "object_type" . tree-walk.h users: refactor chained "mode" if/else into switch . tree-walk.h users: migrate "p->mode &&" pattern . tree.h API: make read_tree_fn_t take an "enum object_type" . archive: get rid of 'stage' parameter . tree.h users: format argument lists in archive.c . tree.h: format argument lists of read_tree_recursive() users . tree-walk.h users: switch object_type(...) to new .object_type . cache.h: have base_name_compare() take "is tree?", not "mode" . diff tests: test that "mode" is passed when sorting . mktree tests: test that "mode" is passed when sorting . fast-import tests: test for sorting dir/file foo v.s. foo.txt . tree-walk.c: migrate to using new "object_type" field when possible . tree-walk.h: add object_type member to name_entry . cache.h: add a comment to object_type() . notes & match-trees: use name_entry's "pathlen" member . diff.c: remove redundant canon_mode() call (this branch uses ab/read-tree.) Code clean-up. I am not exactly sure where this series wants to go, other than unnecessarily churning the code. Seems to break "diff --no-index" rather badly, too (e.g. t4050, t4002, among others).
