What's cooking in git.git (Jun 2018, #02; Mon, 4)

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.

Generally I try to avoid sending issues of "What's cooking" report
in close succession, but as I plan to go offline for most of the
remainder of the week, here is how the tree looks like as of
tonight, just after tagging 2.18-rc1.  Hopefully we'll have another
rc next week and then the real thing a week after that.

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


[Graduated to "master"]

* bc/t3430-fixup (2018-06-04) 1 commit
  (merged to 'next' on 2018-06-04 at 892aab2dc8)
 + t3430: test clean-up

 Test fix.

 + refspec-api: avoid uninitialized field in refspec item


* jt/submodule-pull-recurse-rebase (2018-05-25) 1 commit
  (merged to 'next' on 2018-06-01 at cd3e2a1008)
 + submodule: do not pass null OID to setup_revisions

 "git pull -recurse-submodules --rebase", when the submodule
 repository's history did not have anything common between ours and
 the upstream's, failed to execute.  We need to fetch from them to
 continue even in such a case.

* nd/remote-update-doc (2018-06-04) 2 commits
  (merged to 'next' on 2018-06-04 at b2901b60ad)
 + remote: doc typofix
  (merged to 'next' on 2018-06-04 at 82cce447e5)
 + remote.txt: update documentation for 'update' command

 "git remote update" can take both a single remote nickname and a
 nickname for remote groups, but only one of them was documented.

* rd/p4-doc-markup-env (2018-06-01) 1 commit
  (merged to 'next' on 2018-06-04 at 80212295cf)
 + p4.txt: Use backquotes for variable names

 Doc update.

[New Topics]

* ab/checkout-default-remote (2018-06-04) 8 commits
 - checkout & worktree: introduce checkout.defaultRemote
 - checkout: add advice for ambiguous "checkout <branch>"
 - builtin/checkout.c: use "ret" variable for return
 - checkout: pass the "num_matches" up to callers
 - checkout.c]: change "unique" member to "num_matches"
 - checkout.c: introduce an *_INIT macro
 - checkout.h: wrap the arguments to unique_tracking_name()
 - checkout tests: index should be clean after dwim checkout

* nd/reject-empty-shallow-request (2018-06-04) 1 commit
 - upload-pack: reject shallow requests that would return nothing

 "git fetch --shallow-since=<cutoff>" that specifies the cut-off
 point that is newer than the existing history used to end up
 grabbing the entire history.  Such a request now errors out.

* pw/add-p-recount (2018-06-04) 1 commit
 - add -p: fix counting empty context lines in edited patches

 When user edits the patch in "git add -p" and the user's editor is
 set to strip trailing whitespaces indiscriminately, an empty line
 that is unchanged in the patch would become completely empty
 (instead of a line with a sole SP on it).  The code introduced in
 Git 2.17 timeframe failed to parse such a patch, but now it learned
 to notice the situation and cope with it.

 Will merge to and cook in 'next'.

* rd/comment-typofix-in-sha1-file (2018-06-04) 1 commit

 Instead of mucking with filesystem directly, use plumbing commands
 update-ref etc. to manipulate the refs in the tests.

 Will merge to 'next'.

 - push tests: assert re-pushing annotated tags
 - push tests: add more testing for forced tag pushing
 - push tests: fix logic error in "push" test assertion
 - push tests: remove redundant 'git push' invocation

 Expecting a reboot of the discussion to take it to some conclusion
 and then a reroll.

* pw/add-p-select (2018-03-16) 3 commits
 - add -p: optimize line selection for short hunks
 - add -p: allow line selection to be inverted
 - add -p: select individual hunk lines

 "git add -p" interactive interface learned to let users choose
 individual added/removed lines to be used in the operation, instead
 of accepting or rejecting a whole hunk.

 Expecting a reroll to reignite the discussion.

* jh/json-writer (2018-03-28) 1 commit
 - json_writer: new routines to create data in JSON format

 Preparatory code to later add json output for unspecified telemetry

 We do not add random code that does not have real users to our
 codebase, so let's have it wait until such a real code materializes
 before too long.

* hn/bisect-first-parent (2018-04-21) 1 commit
 - bisect: create 'bisect_flags' parameter in find_bisection()

 Preliminary code update to allow passing more flags down the
 bisection codepath in the future.

 We do not add random code that does not have real users to our
 codebase, so let's have it wait until such a real code materializes
 before too long.

* is/parsing-line-range (2018-06-01) 2 commits
 . log: prevent error if line range ends past end of file
 . blame: prevent error if range ends past end of file

 Parsing of -L[<N>][,[<M>]] parameters "git blame" and "git log"
 take has been tweaked.

 Updated.   Still seems to break a few tests.

* av/fsmonitor-updates (2018-01-04) 6 commits
 - fsmonitor: use fsmonitor data in `git diff`
 - fsmonitor: remove debugging lines from t/t7519-status-fsmonitor.sh

 Code clean-up on fsmonitor integration, plus optional utilization
 of the fsmonitor data in diff-files.

 Waiting for an update.
 cf. <alpine.DEB.>

* mk/http-backend-content-length (2018-06-04) 3 commits
 - SQUASH???
 - http-backend: respect CONTENT_LENGTH for receive-pack
 - http-backend: respect CONTENT_LENGTH as specified by rfc3875

 The http-backend (used for smart-http transport) used to slurp the
 whole input until EOF, without paying attention to CONTENT_LENGTH
 that is supplied in the environment and instead expecting the Web
 server to close the input stream.  This has been fixed.

* jk/drop-ancient-curl (2017-08-09) 5 commits
 - http: #error on too-old curl
 - curl: remove ifdef'd code never used with curl >=7.19.4
 - http: drop support for curl < 7.19.4
 - http: drop support for curl < 7.16.0
 - http: drop support for curl < 7.11.1

 Some code in http.c that has bitrot is being removed.

 Expecting a reroll.

* 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).


* ag/rebase-p (2018-06-01) 4 commits
 - rebase: remove -p code from git-rebase--interactive.sh
 - rebase: use the new git-rebase--preserve-merges.sh
 - rebase: strip unused code in git-rebase--preserve-merges.sh
 - rebase: introduce a dedicated backend for --preserve-merges

 Separate "rebase -p" codepath out of "rebase -i" implementation to
 slim down the latter and make it easier to manage.

 Will merge to 'next'.

* jk/index-pack-maint (2018-06-01) 2 commits
  (merged to 'next' on 2018-06-04 at c553a485e8)
 + index-pack: handle --strict checks of non-repo packs
 + prepare_commit_graft: treat non-repository as a noop

 "index-pack --strict" has been taught to make sure that it runs the
 final object integrity checks after making the freshly indexed
 packfile available to itself.

 Will cook in 'next'.

* ls/complete-remote-update-names (2018-06-01) 1 commit
 - completion: complete remote names too

 "git remote update" can take both a single remote nickname and a
 nickname for remote groups, and the completion script (in contrib/)
 has been taught about it.

 Will merge to and cook in 'next'.

* sb/plug-misc-leaks (2018-06-04) 5 commits
 - SQUASH: tentatively cast const-ness away when calling free()

  (merged to 'next' on 2018-06-04 at fbefac1c7a)
 + sequencer.c: plug leaks in do_pick_commit
 + submodule--helper: plug mem leak in print_default_remote
 + refs/packed-backend.c: close fd of empty file

 Misc leak plugging.

 Will merge to 'next'.

 - advice: keep config name in camelCase in advice_config[]
 - fsck: produce camelCase config key names
 - help: add --config to list all available config
 - fsck: factor out msg_id_info[] lazy initialization code
 - grep: keep all colors in an array
 - Add and use generic name->id mapping code for color slot parsing
 - Merge branch 'nd/command-list' into nd/complete-config-vars

 Continuing with the idea to programatically enumerate various
 pieces of data required for command line completion, teach the
 codebase to report the list of configuration variables
 subcommands care about to help complete them.

 Will merge to and cook in 'next'.

* nd/completion-negation (2018-05-29) 3 commits
 - completion: collapse extra --no-.. options
 - completion: suppress some -no- options
 - parse-options: option to let --git-completion-helper show negative form

 Continuing with the idea to programatically enumerate various
 pieces of data required for command line completion, the codebase
 has been taught to enumerate options prefixed with "--no-" to
 negate them.

 Will merge to and cook in 'next'.

* jm/cache-entry-from-mem-pool (2018-05-24) 7 commits
 - block alloc: add validations around cache_entry lifecyle
 - block alloc: allocate cache entries from mem_pool
 - mem-pool: fill out functionality
 - mem-pool: add lifecycle management functions
 - mem-pool: only search head block for available space
 - block alloc: add lifecycle APIs for cache_entry structs
 - read-cache: teach refresh_cache_entry() to take istate

 For a large tree, the index needs to hold many cache entries
 allocated on heap.  These cache entries are now allocated out of a
 dedicated memory pool to amortize malloc(3) overhead.

* rm/p4-submit-with-commit-option (2018-05-21) 1 commit
 - git-p4: add options --commit and --disable-rebase

 Needs sign-off.

  (merged to 'next' on 2018-05-24 at 3d12a02b0c)
 + commit-graph: fix UX issue when .lock file exists
 (this branch is used by ds/commit-graph-fsck; uses ds/generation-numbers.)

 Update to ds/generation-numbers topic.

 Wait for ds/generation-numbers

* nd/commit-util-to-slab (2018-05-21) 15 commits
  (merged to 'next' on 2018-05-24 at bb5643d75c)
 + commit.h: delete 'util' field in struct commit
 + merge: use commit-slab in merge remote desc instead of commit->util
 + log: use commit-slab in prepare_bases() instead of commit->util
 + show-branch: note about its object flags usage
 + show-branch: use commit-slab for commit-name instead of commit->util
 + name-rev: use commit-slab for rev-name instead of commit->util
 + bisect.c: use commit-slab for commit weight instead of commit->util
 + revision.c: use commit-slab for show_source
 + sequencer.c: use commit-slab to associate todo items to commits
 + sequencer.c: use commit-slab to mark seen commits
 + shallow.c: use commit-slab for commit depth instead of commit->util
 + describe: use commit-slab for commit names instead of commit->util
 + blame: use commit-slab for blame suspects instead of commit->util
 + commit-slab: support shared commit-slab
 + commit-slab.h: code split

 The in-core "commit" object had an all-purpose "void *util" field,
 which was tricky to use especially in library-ish part of the
 code.  All of the existing uses of the field has been migrated to a
 more dedicated "commit-slab" mechanism and the field is eliminated.

 Will cook in 'next'.

* nd/diff-apply-ita (2018-05-29) 4 commits
  (merged to 'next' on 2018-05-30 at f98728de81)
 + apply: add --intent-to-add
 + t2203: add a test about "diff HEAD" case
 + diff: turn --ita-invisible-in-index on by default
 + diff: ignore --ita-[in]visible-in-index when diffing worktree-to-tree

 "git diff" compares the index and the working tree.  For paths
 added with intent-to-add bit, the command shows the full contents
 of them as added, but the paths themselves were not marked as new
 files.  They are now shown as new by default.

 "git apply" learned the "--intent-to-add" option so that an
 otherwise working-tree-only application of a patch will add new
 paths to the index marked with the "intent-to-add" bit.

 Will cook in 'next'.

 - object: move grafts to object parser
 - object-store: move object access functions to object-store.h
 (this branch uses sb/object-store-alloc.)

 The conversion to pass "the_repository" and then "a_repository"
 throughout the object access API continues.

 Will merge to and cook in 'next'.

* pc/submodule-helper-foreach (2018-05-11) 4 commits
  (merged to 'next' on 2018-05-22 at f22659ad46)
 + submodule: port submodule subcommand 'foreach' from shell to C
 + submodule foreach: document variable '$displaypath'

 - Add a function to solve least-cost assignment problems

 "git tbdiff" that lets us compare individual patches in two
 iterations of a topic has been rewritten and made into a built-in

 Expecting a reroll.
 cf. <nycvar.QRO.>

* sb/object-store-alloc (2018-05-16) 13 commits

 . Documentation/config.txt: camel-case lineNumber for consistency
 (this branch is used by tb/grep-only-matching.)

 "git grep" learned the "--column" option that gives not just the
 line number but the column number of the hit.

 Expecting a reroll.
 cf. <20180530160908.GA8340@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>

* tb/grep-only-matching (2018-05-14) 2 commits

 (this branch is used by ds/commit-graph-fsck and ds/commit-graph-lockfile-fix.)

 A recently added "commit-graph" datafile has learned to store
 pre-computed generation numbers to speed up the decisions to stop
 history traversal.

* jk/branch-l-0-deprecation (2018-05-25) 5 commits
  (merged to 'next' on 2018-05-30 at a94574dfd5)
 + branch: customize "-l" warning in list mode
 + branch: issue "-l" deprecation warning after pager starts
  (merged to 'next' on 2018-04-11 at 9b2b0305dd)
 + branch: deprecate "-l" option
 + t: switch "branch -l" to "branch --create-reflog"
 + t3200: unset core.logallrefupdates when testing reflog creation
 (this branch is used by jk/branch-l-1-removal and jk/branch-l-2-reincarnation.)

 The "-l" option in "git branch -l" is an unfortunate short-hand for
 "--create-reflog", but many users, both old and new, somehow expect
 it to be something else, perhaps "--list".  This step deprecates
 the short-hand and warns about the future removal of the it when it
 is used.

 Will cook in 'next'.
 Perhaps merge to 'master' immediately after 2.18 release?

* jk/branch-l-1-removal (2018-05-30) 1 commit
 - branch: drop deprecated "-l" option
 (this branch is used by jk/branch-l-2-reincarnation; uses jk/branch-l-0-deprecation.)

 Following the "git branch -l" deprecation, the short-hand is removed.

 Will keep in 'pu'.

* jk/branch-l-2-reincarnation (2018-05-30) 1 commit
 - branch: make "-l" a synonym for "--list"
 (this branch uses jk/branch-l-0-deprecation and jk/branch-l-1-removal.)

 Following the "git branch -l" removal, "-l" is resurrected as a
 short-hand for "--list".

 Will keep in 'pu'.


* js/runtime-prefix-windows (2018-03-27) 5 commits
 . mingw/msvc: use the new-style RUNTIME_PREFIX helper
 . exec_cmd: provide a new-style RUNTIME_PREFIX helper for Windows
 . exec_cmd: RUNTIME_PREFIX on some POSIX systems
 . Makefile: add Perl runtime prefix support
 . Makefile: generate Perl header from template file

 The Windows port was the first that allowed Git to be installed
 anywhere by having its components refer to each other with relative
 pathnames.  The recent dj/runtime-prefix topic extends the idea to
 other platforms, and its approach has been adopted back in the
 Windows port.

 Ejected, as the parent topic dj/runtime-prefix covers Windows now.

* bp/fsexcludes (2018-04-16) 2 commits
 . fsmonitor: switch to use new fsexcludes logic and remove unused untracked cache based logic
 . fsexcludes: add a programmatic way to exclude files from git's working directory traversal logic

 Can we have a few lines summary here, just like we have for other
 topic ;-) I personally take the overlong title of these commits as
 a sign that they can further be simplified and cleaned up by
 splitting, focusing the scope, etc.

 . revisions.txt: expand tabs to spaces in diagram

 Fix one instance of asciidoctor's misformatting by expanding a tab
 into spaces in a literal block.

 This approach is less maintainable than the approach taken by
 bc/asciidoctor-tab-width topic.
