What's cooking in git.git (Jun 2019, #03; Wed, 12)
--------------------------------------------------
 
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.
 
Git 2.22 final has been tagged.
 
You can find the changes described here in the integration branches
of the repositories listed at

 The commits in a repository can be described by multiple
 commit-graph files now, which allows the commit-graph files to be
 updated incrementally.
 
 Will merge to 'next'.
 
 
* tm/tag-gpgsign-config (2019-06-05) 1 commit

 + list-objects-filter: correct usage of ALLOC_GROW
 
 The filter_data used in the list-objects-filter (which manages a

  (merged to 'next' on 2019-05-29 at c2cfe38955)

 + bundle verify: error out if called without an object database
 
 "git bundle verify" needs to see if prerequisite objects exist in
 the receiving repository, but the command did not check if we are
 in a repository upfront, which has been corrected.
 
 Will merge to 'master'.
 
 
* js/fsmonitor-unflake (2019-05-28) 2 commits
  (merged to 'next' on 2019-05-30 at 1aa850bc59)
 + mark_fsmonitor_valid(): mark the index as changed if needed

* mm/p4-unshelve-windows-fix (2019-05-28) 1 commit
  (merged to 'next' on 2019-05-31 at d45167d723)
 + p4 unshelve: fix "Not a valid object name HEAD0" on Windows
 
 The command line to invoke a "git cat-file" command from inside
 "git p4" was not properly quoted to protect a caret and running a
 broken command on Windows, which has been corrected.
 
 Will merge to 'master'.
 
 
* pb/request-pull-verify-remote-ref (2019-05-28) 2 commits
  (merged to 'next' on 2019-05-31 at 0f73300dfa)
 + request-pull: warn if the remote object is not the same as the local one

 different.
 
 Will merge to 'master'.
 
 
* po/git-help-on-git-itself (2019-05-16) 2 commits

 + Doc: git.txt: remove backticks from link and add git-scm.com/docs
 + git.c: show usage for accessing the git(1) help page
 
 "git help git" was hard to discover (well, at least for some
 people).
 
 Will merge to 'master'.
 
 
* sw/git-p4-unshelve-branched-files (2019-05-28) 1 commit
  (merged to 'next' on 2019-05-30 at e1985f61fc)

* vv/merge-squash-with-explicit-commit (2019-05-28) 1 commit
  (merged to 'next' on 2019-05-29 at 209baa3e55)
 + merge: refuse --commit with --squash
 
 "git merge --squash" is designed to update the working tree and the
 index without creating the commit, and this cannot be countermanded
 by adding the "--commit" option; the command now refuses to work
 when both options are given.
 
 Will merge to 'master'.
 
 
* xl/record-partial-clone-origin (2019-05-29) 1 commit
  (merged to 'next' on 2019-05-31 at dc291fa199)
 + clone: respect user supplied origin name when setting up partial clone
 
 When creating a partial clone, the object filtering criteria is
 recorded for the origin of the clone, but this incorrectly used a
 hardcoded name "origin" to name that remote; it has been corrected
 to honor the "--origin <name>" option.
 
 Will merge to 'master'.
 
 
* ab/fail-prereqs-in-test (2019-05-14) 1 commit
  (merged to 'next' on 2019-05-16 at d1be55f485)

 corrected.
 
 Will merge to 'master'.

  (merged to 'next' on 2019-05-29 at 6ed07afc89)
 + userdiff: fix grammar and style issues
  (merged to 'next' on 2019-05-19 at 9ea1180d6c)
 + userdiff: add Octave
 
 The pattern "git diff/grep" use to extract funcname and words
 boundary for Matlab has been extend to cover Octave, which is more
 or less equivalent.
 
 Will merge to 'master'.

  (merged to 'next' on 2019-05-19 at bf4f2871ab)

  (merged to 'next' on 2019-05-16 at d92c25f800)
 + worktree add: be tolerant of corrupt worktrees
 
 "git worktree add" used to fail when another worktree connected to
 the same repository was corrupt, which has been corrected.

* mh/import-transport-fd-fix (2019-05-16) 2 commits
  (merged to 'next' on 2019-05-19 at 5e86f92f7a)
 + Use xmmap_gently instead of xmmap in use_pack
 + dup() the input fd for fast-import used for remote helpers
 
 The ownership rule for the file descriptor to fast-import remote
 backend was mixed up, leading to unrelated file descriptor getting
 closed, which has been fixed.

* ab/deprecate-R-for-dynpath (2019-05-19) 1 commit
  (merged to 'next' on 2019-05-19 at 944976e981)
 + Makefile: remove the NO_R_TO_GCC_LINKER flag
 
 The way of specifying the path to find dynamic libraries at runtime
 has been simplified.  The old default to pass -R/path/to/dir has been
 replaced with the new default to pass -Wl,-rpath,/path/to/dir,
 which is the more recent GCC uses.  Those who need to build with an
 old GCC can still use "CC_LD_DYNPATH=-R"

* ba/clone-remote-submodules (2019-05-28) 1 commit
  (merged to 'next' on 2019-05-29 at 71972f94c2)
 + clone: add `--remote-submodules` flag
 
 "git clone --recurse-submodules" learned to set up the submodules
 to ignore commit object names recorded in the superproject gitlink
 and instead use the commits that happen to be at the tip of the
 remote-tracking branches from the get-go, by passing the new
 "--remote-submodules" option.
 
 Will merge to 'master'.
 
 
* ds/close-object-store (2019-06-12) 3 commits
 - packfile: rename close_all_packs to close_object_store
 - packfile: close commit-graph in close_all_packs
 - commit-graph: use raw_object_store when closing
 (this branch uses ds/commit-graph-write-refactor; is tangled with ds/commit-graph-incremental.)
 
 The commit-graph file is now part of the "files that the runtime
 may keep open file descriptors on, all of which would need to be
 closed when done with the object store", and the file descriptor to
 an existing commit-graph file now is closed before "gc" finalizes a
 new instance to replace it.

* ml/userdiff-rust (2019-05-30) 2 commits
  (merged to 'next' on 2019-06-12 at 33b88fa9e5)

* pw/rebase-edit-message-for-replayed-merge (2019-05-19) 1 commit
  (merged to 'next' on 2019-05-19 at dc3e30641c)
 + rebase -r: always reword merge -c
 
 A "merge -c" instruction during "git rebase --rebase-merges" should
 give the user a chance to edit the log message, even when there is
 otherwise no need to create a new merge and replace the existing
 one (i.e. fast-forward instead), but did not.  Which has been
 corrected.
 
 Will merge to 'master'.
 
 
* sb/format-patch-base-patch-id-fix (2019-05-08) 2 commits
  (merged to 'next' on 2019-05-15 at 1ab7d2b71c)
 + format-patch: make --base patch-id output stable
 + format-patch: inform user that patch-id generation is unstable
 
 The "--base" option of "format-patch" computed the patch-ids for
 prerequisite patches in an unstable way, which has been updated to
 compute in a way that is compatible with "git patch-id --stable".
 
 Will merge to 'master'.

 + send-email: fix broken transferEncoding tests
 + send-email: remove cargo-culted multi-patch pattern in tests
  (merged to 'next' on 2019-05-13 at 38c6a1e7e0)
 + send-email: do defaults -> config -> getopt in that order
 + send-email: rename the @bcclist variable for consistency
 + send-email: move the read_config() function above getopts
 
 Since "git send-email" learned to take 'auto' as the value for the
 transfer-encoding, it by mistake stopped honoring the values given
 to the configuration variables sendemail.transferencoding and/or
 sendemail.<ident>.transferencoding.  This has been corrected to
 (finally) redoing the order of setting the default, reading the
 configuration and command line options.
 
 Will merge to 'master'.

 + init: make --template path relative to $CWD
 
 A relative pathname given to "git init --template=<path> <repo>"
 ought to be relative to the directory "git init" gets invoked in,
 but it instead was made relative to the repository, which has been
 corrected.

 advancing the current history" out of the single "git checkout"
 command.

 "git rebase --keep-base <upstream>" tries to find the original base
 of the topic being rebased and rebase on top of that same base,
 which is useful when running the "git rebase -i" (and its limited
 variant "git rebase -x").
 
 The command also has learned to fast-forward in more cases where it
 can instead of replaying to recreate identical commits.
 
 On hold.

  (merged to 'next' on 2019-05-16 at 9a2dd33122)
 + worktree add: sanitize worktree names
 
 In recent versions of Git, per-worktree refs are exposed in
 refs/worktrees/<wtname>/ hierarchy, which means that worktree names
 must be a valid refname component.  The code now sanitizes the names
 given to worktrees, to make sure these refs are well-formed.
