What's cooking in git.git (Nov 2017, #02; Mon, 6)

Here are the topics that have been cooking.  Commits prefixed with
'-' are only in '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.

Early batches for the next cycle has been merged to 'master' and
'next' has become thin enough so that we can rewind it and rebuild
it as usual, optionally with a handful of topics kicked out of it.
That hasn't happened yet, but it will shortly.

The status description of some of the topics in this report may need
updates that I should have made but forgotten.  Sorry about that.

You can find the changes described here in the integration branches
of the repositories listed at


[Graduated to "master"]

* ao/check-resolve-ref-unsafe-result (2017-10-21) 1 commit
  (merged to 'next' on 2017-10-26 at 84302ab59a)
 + commit: check result of resolve_ref_unsafe

 "git commit", after making a commit, did not check for errors when
 asking on what branch it made the commit, which has been correted.

* bc/object-id (2017-10-16) 25 commits

 + refs: convert delete_ref and refs_delete_ref to struct object_id
 + refs/files-backend: convert struct ref_to_prune to object_id
 + walker: convert to struct object_id
 (this branch is used by mh/tidy-ref-update-flags.)

 Conversion from uchar[20] to struct object_id continues.

* bw/grep-recurse-submodules (2017-11-02) 1 commit
  (merged to 'next' on 2017-11-02 at 50bbebe9e3)
 + grep: take the read-lock when adding a submodule

 A broken access to object databases in recent update to "git grep
 --recurse-submodules" has been fixed.

* cn/diff-indent-no-longer-is-experimental (2017-11-02) 1 commit
  (merged to 'next' on 2017-11-02 at d3fe3952a7)
 + diff: --indent-heuristic is no longer experimental

 Doc update.

* dm/run-command-ignored-hook-advise (2017-10-10) 1 commit
  (merged to 'next' on 2017-10-10 at 0827814922)
 + run-command: add hint when a hook is ignored

 A hook script that is set unexecutable is simply ignored.  Git
 notifies when such a file is ignored, unless the message is
 squelched via advice.ignoredHook configuration.

* ds/find-unique-abbrev-optim (2017-10-13) 4 commits
  (merged to 'next' on 2017-10-16 at 7f4479ac52)
 + sha1_name: minimize OID comparisons during disambiguation
 + sha1_name: parse less while finding common prefix
 + sha1_name: unroll len loop in find_unique_abbrev_r()
 + p4211-line-log.sh: add log --online --raw --parents perf test

 Optimize the code to find shortest unique prefix of object names.

* ex/deprecate-empty-pathspec-as-match-all (2017-06-23) 2 commits
  (merged to 'next' on 2017-08-14 at 24db08a6e8)
 + pathspec: die on empty strings as pathspec
 + t0027: do not use an empty string as a pathspec element

 The final step to make an empty string as a pathspec element
 illegal.  We started this by first deprecating and warning a
 pathspec that has such an element in 2.11 (Nov 2016).

* gc/gitweb-filetest-acl (2017-10-24) 1 commit
  (merged to 'next' on 2017-10-26 at 5b490f53bf)
 + gitweb: use filetest to allow ACLs

 "gitweb" checks if a directory is searchable with Perl's "-x"
 operator, which can be enhanced by using "filetest 'access'"
 pragma, which now we do.

* hv/fetch-moved-submodules-on-demand (2017-10-17) 3 commits
  (merged to 'next' on 2017-10-26 at c446ea3e9a)
 + submodule: simplify decision tree whether to or not to fetch
 + implement fetching of moved submodules
 + fetch: add test to make sure we stay backwards compatible

 "git fetch --recurse-submodules" now knows that submodules can be
 moved around in the superproject in addition to getting updated,
 and finds the ones that need to be fetched accordingly.

* jc/check-ref-format-oor (2017-10-18) 3 commits
  (merged to 'next' on 2017-10-18 at 8b17566c80)
 + check-ref-format doc: --branch validates and expands <branch>
 + check-ref-format --branch: strip refs/heads/ using skip_prefix
 + check-ref-format --branch: do not expand @{...} outside repository

 "git check-ref-format --branch @{-1}" bit a "BUG()" when run
 outside a repository for obvious reasons; clarify the documentation
 and make sure we do not even try to expand the at-mark magic in
 such a case, but still call the validation logic for branch names.

* jc/no-cmd-as-subroutine (2017-10-11) 2 commits
  (merged to 'next' on 2017-10-16 at 5f4ee919ac)
 + merge-ours: do not use cmd_*() as a subroutine
 + describe: do not use cmd_*() as a subroutine

 Calling cmd_foo() as if it is a general purpose helper function is
 a no-no.  Correct two instances of such to set an example.

* jc/t5601-copy-workaround (2017-10-17) 1 commit
  (merged to 'next' on 2017-10-18 at ea1e133968)
 + t5601: rm the target file of cp that could still be executing

 A (possibly flakey) test fix.

* jk/diff-color-moved-fix (2017-10-21) 5 commits
  (merged to 'next' on 2017-10-26 at eb580e4c8c)
 + diff: handle NULs in get_string_hash()
 + diff: fix whitespace-skipping with --color-moved
 + t4015: test the output of "diff --color-moved -b"
 + t4015: check "negative" case for "-w --color-moved"
 + t4015: refactor --color-moved whitespace test
 (this branch is used by sb/diff-color-moved-use-xdl-recmatch.)

 The experimental "color moved lines differently in diff output"
 feature was buggy around "ignore whitespace changes" edges, whihch
 has been corrected.

* jk/misc-resolve-ref-unsafe-fixes (2017-10-21) 4 commits
  (merged to 'next' on 2017-10-26 at c327b2ec2f)
 + worktree: handle broken symrefs in find_shared_symref()
 + log: handle broken HEAD in decoration check
 + remote: handle broken symrefs
 + test-ref-store: avoid passing NULL to printf

 Some codepaths did not check for errors when asking what branch the
 HEAD points at, which have been fixed.

* jk/rebase-i-exec-gitdir-fix (2017-11-02) 1 commit
  (merged to 'next' on 2017-11-02 at 9a519c7150)
 + sequencer: pass absolute GIT_DIR to exec commands

 A recent regression in "git rebase -i" that broke execution of git
 commands from subdirectories via "exec" insn has been fixed.

* jk/revision-pruning-optim (2017-10-14) 1 commit
  (merged to 'next' on 2017-10-16 at 2662baa21d)
 + revision: quit pruning diff more quickly when possible

 Pathspec-limited revision traversal was taught not to keep finding
 unneeded differences once it knows two trees are different inside
 given pathspec.

* js/submodule-in-excluded (2017-10-26) 1 commit
  (merged to 'next' on 2017-10-26 at 2a262e6a0b)
 + status: do not get confused by submodules in excluded directories

 "git status --ignored -u" did not stop at a working tree of a
 separate project that is embedded in an ignored directory and
 listed files in that other project, instead of just showing the
 directory itself as ignored.

* kd/auto-col-with-pager-fix (2017-10-24) 2 commits
  (merged to 'next' on 2017-10-24 at ef3ff0f14b)
 + column: do not include pager.c
  (merged to 'next' on 2017-10-18 at fe89ff7e83)
 + column: show auto columns when pager is active

 "auto" as a value for the columnar output configuration ought to
 judge "is the output consumed by humans?" with the same criteria as
 "auto" for coloured output configuration, i.e. either the standard
 output stream is going to tty, or a pager is in use.  We forgot the
 latter, which has been fixed.

* ma/lockfile-fixes (2017-10-07) 12 commits
  (merged to 'next' on 2017-10-16 at 19fae5c138)
 + read_cache: roll back lock in `update_index_if_able()`
 + read-cache: leave lock in right state in `write_locked_index()`
 + read-cache: drop explicit `CLOSE_LOCK`-flag
 + cache.h: document `write_locked_index()`
 + apply: remove `newfd` from `struct apply_state`
 + apply: move lockfile into `apply_state`
 + cache-tree: simplify locking logic
 + checkout-index: simplify locking logic
 + tempfile: fix documentation on `delete_tempfile()`
 + lockfile: fix documentation on `close_lock_file_gently()`
 + treewide: prefer lockfiles on the stack
 + sha1_file: do not leak `lock_file`

 An earlier update made it possible to use an on-stack in-core
 lockfile structure (as opposed to having to deliberately leak an
 on-heap one).  Many codepaths have been updated to take advantage
 of this new facility.

* mh/test-local-canary (2017-10-31) 1 commit
  (merged to 'next' on 2017-11-02 at f34927f687)
 + t0000: check whether the shell supports the "local" keyword

 We try to see if somebody runs our test suite with a shell that
 does not support "local" like bash/dash does.

* mp/push-pushoption-config (2017-10-24) 1 commit
  (merged to 'next' on 2017-10-26 at 2c72164d12)
 + builtin/push.c: add push.pushOption config

 The "--push-option=<string>" option to "git push" now defaults to a
 list of strings configured via push.pushOption variable.

* pb/bisect-helper (2017-10-06) 6 commits
  (merged to 'next' on 2017-10-13 at ffc9aefe63)
 + bisect--helper: `is_expected_rev` & `check_expected_revs` shell function in C
 + t6030: explicitly test for bisection cleanup
 + bisect--helper: `bisect_clean_state` shell function in C
 + bisect--helper: `write_terms` shell function in C
 + bisect--helper: rewrite `check_term_format` shell function in C
 + bisect--helper: use OPT_CMDMODE instead of OPT_BOOL
 (this branch is used by pb/bisect-helper-2.)

 An early part of piece-by-piece rewrite of "git bisect".

* pc/submodule-helper (2017-10-07) 3 commits
  (merged to 'next' on 2017-10-16 at 2b38de12cc)
 + submodule: port submodule subcommand 'status' from shell to C
 + submodule--helper: introduce for_each_listed_submodule()
 + submodule--helper: introduce get_submodule_displaypath()


* sb/diff-color-moved-use-xdl-recmatch (2017-10-26) 2 commits
  (merged to 'next' on 2017-10-26 at 6711f24498)
 + diff.c: get rid of duplicate implementation
 + xdiff-interface: export comparing and hashing strings
 (this branch uses jk/diff-color-moved-fix.)

 Instead of using custom line comparison and hashing functions to
 implement "moved lines" coloring in the diff output, use the pair
 of these functions from lower-layer xdiff/ code.

* tb/complete-checkout (2017-10-25) 1 commit
  (merged to 'next' on 2017-10-26 at beeaf5b00c)
 + completion: add remaining flags to checkout

 Command line completion (in contrib/) update.

* tg/deprecate-stash-save (2017-10-27) 3 commits
  (merged to 'next' on 2017-10-27 at 73b1edb73b)
 + stash: remove now superfluos help for "stash push"
 + stash: mark "git stash save" deprecated in the man page
 + stash: replace "git stash save" with "git stash push" in the documentation

 "git stash save" has been deprecated in favour of "git stash push".

* wk/pull-signoff (2017-10-13) 1 commit
  (merged to 'next' on 2017-10-16 at 5e48f349d9)
 + pull: pass --signoff/--no-signoff to "git merge"

 "git pull" has been taught to accept "--[no-]signoff" option and
 pass it down to "git merge".

 - fsck: support promisor objects as CLI argument
 - fsck: support referenced promisor objects
 - fsck: support refs pointing to promisor objects
 - fsck: introduce partialclone extension
 - extension.partialclone: introduce partial clone extension
 (this branch is used by jh/partial-clone; uses jh/object-filtering.)

* jh/object-filtering (2017-11-03) 6 commits
 - pack-objects: add list-objects filtering
 - rev-list: add list-objects filtering support
 - list-objects: filter objects in traverse_commit_list

 Correct start-up sequence so that a repository could hang
 immediately under the root directory again (which was broken at
 around Git 2.13).

 Will merge to 'next'.

 - fixup! ssh: 'auto' variant to select between 'ssh' and 'simple'
 - ssh: 'simple' variant does not support --port
 - ssh: 'simple' variant does not support -4/-6
 - ssh: 'auto' variant to select between 'ssh' and 'simple'
 - connect: split ssh command line options into separate function
 - connect: split git:// setup into a separate function
 (this branch uses bw/protocol-v1.)

 The ssh-variant 'simple' introduced earlier broke existing
 installations by not passing --port/-4/-6 and not diagnosing an
 attempt to pass these as an error.  Instead, default to
 automatically detect how compatible the GIT_SSH/GIT_SSH_COMMAND is
 to OpenSSH convention and then error out an invocation to make it
 easier to diagnose connection errors.

 Expecting a reroll.

* js/for-each-ref-remote-name-and-ref (2017-10-11) 3 commits
 - for-each-ref: test :remotename and :remoteref
 - for-each-ref: let upstream/push optionally report the remote ref name
 - for-each-ref: let upstream/push optionally report the remote name

 The "--format=..." option "git for-each-ref" takes learned to show
 the name of the 'remote' repository and the ref at the remote side
 that is affected for 'upstream' and 'push' via "%(push:remotename)"
 and friends.

 Needs a bit more work on the documentation part.

* jc/merge-symlink-ours-theirs (2017-09-26) 1 commit
 - merge: teach -Xours/-Xtheirs to symbolic link merge

 "git merge -Xours/-Xtheirs" learned to use our/their version when
 resolving a conflicting updates to a symbolic link.

 Needs review.

* mg/merge-base-fork-point (2017-09-17) 3 commits
 - merge-base: find fork-point outside partial reflog
 - merge-base: return fork-point outside reflog
 - t6010: test actual test output

 "merge-base --fork-point $branch $commit" is used to guess on which
 commit among the commits that were once at the tip of the $branch the
 $commit was built on top of, and it learns these historical tips from
 the reflog of the $branch.  When the true fork-point is lost due to
 pruning of old reflog entries, the command does not give any output,
 because it has no way to guess correctly and does not want to mislead
 the user with a wrong guess.

 The command has been updated to give the best but not known to be
 correct guess, based on a hope that a merge-base between $commit and a
 virtual merge across all the reflog entries that still are available
 for $branch may still be a closer to the true fork-point than the
 merge-base between $commit and the current tip of the $branch.

 This may have to be offered by an additional option, to allow the
 users that are prepared to see a potentially incorrect guess to opt
 into the feature, without affecting the current callers that may not
 be prepared to accept a guess that is not known to be correct.

 What's the doneness of this one?

* mk/use-size-t-in-zlib (2017-08-10) 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".

 Needs resurrecting by making sure the fix is good and still applies
 (or adjusted to today's codebase).

* mg/status-in-progress-info (2017-05-10) 2 commits
 - status --short --inprogress: spell it as --in-progress
 - status: show in-progress info for short status

 - add: introduce "--renormalize"

 "git add --renormalize ." is a new and safer way to record the fact
 that you are correcting the end-of-line convention and other

* jm/status-ignored-files-list (2017-10-31) 4 commits
  (merged to 'next' on 2017-11-01 at fe51978a30)
 + status: test ignored modes
 + status: document options to show matching ignored files
 + status: report matching ignored and normal untracked
 + status: add option to show ignored files differently

 The set of paths output from "git status --ignored" was tied
 closely with its "--untracked=<mode>" option, but now it can be
 controlled more flexibly.  Most notably, a directory that is
 ignored because it is listed to be ignored in the ignore/exclude
 mechanism can be handled differently from a directory that ends up
 to be ignored only because all files in it are ignored.

 Will merge to 'master'.

 Is there any remaining issues on this one?

* jm/svn-pushmergeinfo-fix (2017-09-17) 1 commit
 - git-svn: fix svn.pushmergeinfo handling of svn+ssh usernames.

 "git svn dcommit" did not take into account the fact that a
 svn+ssh:// URL with a username@ (typically used for pushing) refers
 to the same SVN repository without the username@ and failed when
 svn.pushmergeinfo option is set.

 Needs a test, perhaps as a follow-up patch.

 + fsmonitor: add documentation for the fsmonitor extension.
 + fsmonitor: teach git to optionally utilize a file system monitor to speed up detecting new or changed files.
 + update-index: add a new --force-write-index option
 + preload-index: add override to enable testing preload-index

 We learned to talk to watchman to speed up "git status" and other
 operations that need to see which paths have been modified.

* sb/submodule-recursive-checkout-detach-head (2017-07-28) 2 commits
  (merged to 'next' on 2017-10-26 at 30994b4c76)
 + Documentation/checkout: clarify submodule HEADs to be detached
 + recursive submodules: detach HEAD from new state

 "git checkout --recursive" may overwrite and rewind the history of
 the branch that happens to be checked out in submodule
 repositories, which might not be desirable.  Detach the HEAD but
 still allow the recursive checkout to succeed in such a case.

 This needs justification in a larger picture; it is unclear why
 this is better than rejecting recursive checkout, for example.


* jk/ui-color-always-to-auto-maint (2017-10-13) 2 commits
  (merged to 'next' on 2017-10-13 at bb16e1edc8)
 + color: document that "git -c color.*=always" is a bit special
 + color: downgrade "always" to "auto" only for on-disk configuration

 It turns out that "git -c color.ui=always cmd" is relied on by many
 third-party tools as a way to force coloured output no matter what
 the end-user configuration is, and a recent attempt to downgrade
 'always' to 'auto' to fix the regression to "git add -p" broke it.

 This has been reverted from 'next'.

* jh/dir-add-exclude-from-blob (2017-10-27) 1 commit
 - dir: allow exclusions from blob in addition to file

 The code to read exclusion list from a blob, which is used when the
 .gitignore file is outside a sparse checkout area, has been
 refactored so that other codepath can later use it to do the same
 outside the context of "sparse checkout".

 Now part of jh/object-filtering topic.
