tests: de-flake test-narrow-share.t by making dirstate predictable test-narrow-share.t was sometimes (~0.5% on my machine) failing like this: @@ -61,7 +61,7 @@ A d3/g $ hg -R main debugdirstate --no-dates n 644 2 set d1/f - n 644 2 unset d3/f + n 644 2 set d3/f a 0 -1 unset d3/g n 644 2 set d5/f n 644 2 set d7/f The timestamp for d3/f would get set if it was determined at some point that it was clean. That check is usually done when the user runs `hg st`. We don't do that before the failure in the test case, but it happens at the end of the `hg clone` call. So if the file system's time happens to roll over after the clone's working copy has been written, but before its (final) dirstate has been written, we can end up with a set timestamp there. This patch makes it consistent by sleeping for 2 seconds so the timestamp gets reliably set. Differential Revision: https://phab.mercurial-scm.org/D5568

convert: don't drop commits that are empty in the source when using --filemap I ran into this when using `hg lfconvert --to-normal` (which uses the filemap class internally), and saw that commits with nothing but a branch change were dropped. We could put in an option that only lfconvert uses internally. But silently dropping anything other than a commit where all changes were excluded seems unintended. For example, there's a message in mercurial_sink.putcommit() if it drops an empty commit. (And the reason that isn't kicking in here is because lfconvert isn't passing --filemap, so the self.filemapmode conditional there is always False.) The naive change of `return not files` broke test-convert-filemap.t, so this is a little more elaborate than needed for converting from largefiles.

convert: add missing numcommits() override to hg sources Otherwise, the progressbar in converter.walktree() gets None as its total during the initial scan. (Though that seems harmless, and there are other foreign vcs sources without this.)

testrunner: make `-j100 --runs-per-test=100 test-foo.t` use 100 jobs It would use only 1 job since 1039404c5e1d (run-tests: print number of tests and parallel process count, 2018-10-13), but I'm pretty sure that was unintentional. Differential Revision: https://phab.mercurial-scm.org/D5557

narrow: use merge.ACTION_GET instead of duplicating 'g' constant As suggested by Yuya. Differential Revision: https://phab.mercurial-scm.org/D5512

narrow: drop explicit dirstate write The dirstate is written when the wlock is released, so we don't need to write it explicitly in updateworkingcopy(). I don't know why I put it there in the first place (tests pass without it even in the commit that introduced it). Differential Revision: https://phab.mercurial-scm.org/D5515

histedit: fix --continue and --abort when curses is enabled I overlooked this when I did the initial import. Differential Revision: https://phab.mercurial-scm.org/D5540

graft: abort if --date/user specified with --currentdate/currentuser (BC) They are conflicting options. Let's explicitly ban such combination. Note that this means you need "--no-currentdate --date" to override --currentdate specified in aliases/defaults.

amend: turn currentdate into tri-state bool so config option can be negated Otherwise, rewrite.update-timestap couldn't be overridden by --no-currentdate. FWIW, which do we like? --no-currentdate vs --no-current-date. If the latter is preferred, maybe we can add "graft --current-date" and deprecate "--currentdate".

discovery: improve partial discovery documentation The older documentation could be improved.
