* ac/log-use-mailmap-by-default-transition (2019-07-15) 3 commits
- tests: defang pager tests by explicitly disabling the log.mailmap warning
- documentation: mention --no-use-mailmap and log.mailmap false setting
- log: add warning for unspecified log.mailmap setting
* br/blame-ignore (2019-07-01) 11 commits
(merged to 'next' on 2019-07-01 at f4b79421c9)
+ t8014: remove unnecessary braces

+ blame: add a fingerprint heuristic to match ignored lines
+ blame: optionally track line fingerprints during fill_blame_origin()
+ blame: add config options for the output of ignored or unblamable lines
+ blame: add the ability to ignore commits and their changes
+ blame: use a helper function in blame_chunk()
+ Move oidset_parse_file() to oidset.c
+ fsck: rename and touch up init_skiplist()

The "git log" command learns to issue a warning when log.mailmap
configuration is not set and --[no-]mailmap option is not used, to
prepare users for future versions of Git that uses the mailmap by
default.

Will merge to 'next'.
"git blame" learned to "ignore" commits in the history, whose
effects (as well as their presence) get ignored.

We have been trying out a few language features outside c89; the
coding guidelines document did not talk about them and instead had
a blanket ban against them.

Will merge to 'next'.
The commits in a repository can be described by multiple
commit-graph files now, which allows the commit-graph files to be
updated incrementally.

* sr/gpg-interface-stop-at-the-end (2019-07-16) 1 commit

* ea/merge-code-cleanup (2019-07-09) 1 commit
(merged to 'next' on 2019-07-11 at a7b831b03e)
+ builtin/merge.c - cleanup of code in for-cycle that tests strategies

A codepath that reads from GPG for signed object verification read
past the end of allocated buffer, which has been fixed.

Will merge to 'next'.
A loop has been rewritten for conciseness and clarity.


* tg/stash-keep-index-with-removed-paths (2019-07-16) 1 commit

* ew/repack-with-bitmaps-by-default (2019-07-01) 1 commit
(merged to 'next' on 2019-07-09 at 985419cb6e)
+ repack: disable bitmaps-by-default if .keep files exist

"git stash --keep-index" did not work correctly on paths that have
been removed, which has been fixed.

Will merge to 'next'.
Generation of pack bitmaps are now disabled when .keep files exist,
as these are mutually exclusive features.


* jc/denoise-rm-to-resolve (2019-07-18) 1 commit

* jk/check-connected-with-alternates (2019-07-01) 2 commits
(merged to 'next' on 2019-07-09 at b5888bd955)
+ check_everything_connected: assume alternate ref tips are valid
+ object-store.h: move for_each_alternate_ref() from transport.h

"git rm" to resolve a conflicted path leaked an internal message
"needs merge" before actually removing the path, which was
confusing. This has been corrected.

Will merge to 'next'.
The tips of refs from the alternate object store can be used as
starting point for reachability computation now.

+ status: remove the empty line after hints

"git clean" silently skipped a path when it cannot lstat() it; now
it gives a warning.

Will merge to 'next'.
Extra blank lines in "git status" output have been reduced.

+ t7814: do not generate same commits in different repos
+ Use the right 'struct repository' instead of the_repository
+ match-trees.c: remove the_repo from shift_tree*()
+ tree-walk.c: remove the_repo from get_tree_entry_follow_symlinks()
+ tree-walk.c: remove the_repo from get_tree_entry()
+ tree-walk.c: remove the_repo from fill_tree_descriptor()
+ sha1-file.c: remove the_repo from read_object_with_reference()

The tree-walk API learned to pass an in-core repository
instance throughout more codepaths.


* pw/prompt-cherry-pick-revert-fix (2019-07-01) 1 commit
(merged to 'next' on 2019-07-09 at bf8f0af685)

When one step in multi step cherry-pick or revert is reset or

current status, which has been improved.
