revset: move weight information to predicate Previously revset weight is hardcoded and cannot be modified. This patch moves it to predicate so newly registered revsets could define their weight to properly give static optimization some hint. Differential Revision: https://phab.mercurial-scm.org/D657

revset: remove "small" argument from "_optimize" `_optimize` calculates weights of subtrees. "small" affects some weight calculation (either 1 or 0.5). The weights are now only useful in `and` optimization where we might swap two arguments and use `andsmally`. In the real world, it seems unlikely that revsets with weight of 0.5 or 1 matters the `and` order optimization. I think the important thing is to get weights of expensive revsets right (ex. `contains`). This patch removes the `small` argument to simplify the interface. As for choosing between 0.5 vs 1, things returning a single revision (`ancestor`, `string`) has a weight of 0.5. Things returning multiple revisions returns 1. This could be sometimes useful in the `andsmally` optimization, ex. (((:)-2) & expensive()) & ((1-2) & expensive()) ^^^ ^ ^^^^^^^ ^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^ weight=1 weight=0.5 would have an `andsmally` optimization so `1-2` gets executed first, which seems to be desirable.

ui: fix progress debug log format strings to work on Python 3

tests: update `f` helper script to work on Python 3

tests: fix run-tests XML reporting on Python 3 cdatasafe wants to work in terms of bytes, but of course we have a unicode. Easy to work around, especially since we know we'll get utf-8 at the end.

tests: convert bisect support regex to binary The bisection feature of run-tests still fails tests with this because bisect itself doesn't work yet. We'll get there.

tests: decode bytes path to hg command before hitting with shellquote

tests: fix test-is-whitelisted check in run-tests Again, look for bytes in a set of bytes objects.

tests: fix run-tests "slow test" check Look for bytes in a set of bytes objects.

tests: fix run-tests default values in Test constructor As far as I can tell, default values are evaluated far earlier on Python 3.6 than 2.7, meaning we've got to be more careful about when we read the defaults dictionary for the kwarg defaults. Sigh. With this change, test-run-tests.t is significantly less of a mess under 3.6.

tests: add support for listing tests to run in a file This will make it easier for us to run the tests in the python3 whitelist in buildbot.

python3: remove test-update-dest.t from the whitelist I've poked at this on and off several times, and I can't figure out what regressed. Let's kick this out of the whitelist for now so that we can get the *rest* of our progress covered by the buildbots.

bundle2: move part processing to a separate function Now that the part processing loop is tiny, let's move it to a separate function. This will allow extensions to completely replace the part processing logic, without having to replace the overall bundle processing logic or the stream maintenance logic. This will be useful for the infinitepush extension, so it can completely take over receiving a bundle and rerouting it to a side store. This will also make it easier to upstream the infinitepush functionality later. Differential Revision: https://phab.mercurial-scm.org/D709

bundle2: remove unnecessary try finally This is no longer needed. Differential Revision: https://phab.mercurial-scm.org/D708

bundle2: move handler validation out of processpart As part of refactoring bundle part processing let's move handler validation to its own function. Differential Revision: https://phab.mercurial-scm.org/D707
