[New Topics]

* cb/windows-manifest (2019-06-27) 1 commit
- mingw: embed a manifest to trick UAC into Doing The Right Thing
* bc/hash-independent-tests-part-4 (2019-07-01) 10 commits
- t2203: avoid hard-coded object ID values
- t1710: make hash independent
- t1007: remove SHA1 prerequisites
- t0090: make test pass with SHA-256
- t0027: make hash size independent
- t6030: make test work with SHA-256
- t5000: make hash independent
- t1450: make hash size independent
- t1410: make hash size independent
- t: add helper to convert object IDs to paths

Windows update.
Update to the tests to help SHA-256 transition continues.


* pw/prompt-cherry-pick-revert-fix (2019-07-01) 1 commit
- git-prompt: improve cherry-pick/revert detection

When one step in multi step cherry-pick or revert is reset or
committed, the command line prompt script failed to notice the
current status, which has been improved.

Will merge to 'next'.


* js/mingw-gcc-stash-protect (2019-06-27) 1 commit
- mingw: enable stack smashing protector
* pw/rebase-progress-test-cleanup (2019-07-01) 1 commit
- t3420: remove progress lines before comparing output
(this branch uses sg/rebase-progress.)

Windows update.
Test cleanup.

Will merge to 'next'.


* js/mingw-use-utf8 (2019-06-27) 2 commits
- mingw: use Unicode functions explicitly
- mingw: get pw_name in UTF-8 format
* sg/git-C-empty-doc (2019-07-01) 1 commit
- Document that 'git -C ""' works and doesn't change directory

Windows update.
Doc update.

Will merge to 'next'.


* kb/windows-force-utf8 (2019-06-27) 1 commit
- gettext: always use UTF-8 on native Windows
* es/local-atomic-push-failure-with-http (2019-07-02) 2 commits
- SQUASH???
- transport-helper: enforce atomic in push_refs_with_push

Windows update.
"git push --atomic" that goes over the transport-helper (namely,
the smart http transport) failed to prevent refs to be pushed when
it can locally tell that one of the ref update will fail without
having to consult the other end, which has been corrected.

Need to either wait for reroll or squash the fix in directly.


* es/walken-tutorial (2019-07-02) 1 commit
- documentation: add tutorial for revision walking

Yet another revision walker tutorial.


* qn/clone-doc-use-long-form (2019-07-02) 2 commits
- docs: git-clone: list short form of options first
- docs: git-clone: refer to long form of options

The "git clone" documentation refers to command line options in its
description in the short form; they have been replaced with long
forms to make them more recognisable.

Will merge to 'next'.


* js/rebase-reschedule-applies-only-to-interactive (2019-06-27) 1 commit
- rebase: ignore rebase.reschedulefailedexec unless interactive
* sg/ci-brew-gcc-workaround (2019-07-03) 2 commits
- ci: disable Homebrew's auto cleanup
- ci: don't update Homebrew

The configuration variable rebase.rescheduleFailedExec should be
effective only while running an interactive rebase and should not
affect anything when running an non-interactive one, which was not
the case. This has been corrected.

Almost there, modulo minor nits.


* jt/t5551-test-chunked (2019-06-27) 1 commit
- t5551: test usage of chunked encoding explicitly

Update smart-http test.
Dev support update.

Will merge to 'next'.


* tb/ref-filter-multiple-patterns (2019-06-27) 1 commit
- ref-filter.c: find disjoint pattern prefixes

"git for-each-ref" with multiple patterns have been optimized.

Will merge to 'next'.


* ew/repack-with-bitmaps-by-default (2019-06-28) 1 commit
- repack: disable bitmaps-by-default if .keep files exist

Generation of pack bitmaps are now disabled when .keep files exist,
as these are mutually exclusive features.


* jk/br-blame-ignore-unused-fix (2019-06-28) 1 commit
- blame: drop some unused function parameters
(this branch uses br/blame-ignore.)

Move this into the base topic, once acked.


* jk/check-connected-with-alternates (2019-06-28) 1 commit
- check_connected: assume alternate ref tips are valid

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

Will merge to 'next'.


* jk/test-commit-bulk (2019-06-28) 6 commits
- t6200: use test_commit_bulk
- t5703: use test_commit_bulk
- t5702: use test_commit_bulk
- t3311: use test_commit_bulk
- t5310: increase the number of bitmapped commits
- test-lib: introduce test_commit_bulk

A test helper has been introduced to optimize preparation of test
repositories with many simple commits, and a handful of test
scripts have been updated to use it.

Will merge to 'next'.
I think I spotted one unused command, which we may want to remove, though.
