py3: make second argument of fdopen() a str # skip-blame as just r'' prefixes Differential Revision: https://phab.mercurial-scm.org/D5260

py3: fix keyword arguments handling in hgext/remotefilelog/ Keys of kwargs on Python 3 should be strings. This patch fixes them by appending r'' prefixes, and using pycompat.byteskwargs() and pycompat.strkwargs(). Differential Revision: https://phab.mercurial-scm.org/D5259

py3: add __pycache__ to .hgignore Something changed with Python 3 just like million on things. Maybe they should named Python 3 as anaconda or cobra instead of just increasing the version number. This makes test-custom-filters.t pass on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5039

sparse-revlog: stop using a heap to track selected gap Same logic as for 'gapsheap', we don't actually need a heap.

sparse-revlog: stop using a heap to track gaps The heap doesn't bring any performance advantage as we can simply sort the final list. Moreover, the lesser complexity helps a lot when we later implement it in C.

sparse-revlog: fast-path before computing payload size In this fast-path case, we do not need to compute the full delta chain payload. Since it comes with a significant cost, we avoid doing so if possible.

sparse-revlog: drop unused deltainfo parameter from segmentspan We no longer need to deal with slicing logic including uncommitted revision. We drop the associated code.

sparse-revlog: drop unused deltainfo parameter from _slicechunktodensity We no longer need to deal with slicing logic including uncommitted revision. We drop the associated code.

sparse-revlog: skip the span check in the sparse-revlog case This significantly improves the performance on unbundling on smaller repositories.

histedit: import chistedit curses UI from hg-experimental I don't tend to like curses interfaces, but this gets enough use at work that it seems like it's worth bringing into core. This is a minimal import from hg-experimental revision 4c7f33bf5f00, in that I've done the smallest amount of code movement and editing in order to import the functionality. .. feature:: `hg histedit` will now present a curses UI if curses is available and `ui.interface` or `ui.interface.histedit` is set to `curses`.

manifest: perform cheap checks before potentially allocating memory Differential Revision: https://phab.mercurial-scm.org/D5258

manifest: also reject obviously-too-short lines when parsing lines Differential Revision: https://phab.mercurial-scm.org/D5257

manifest: make sure there's a filename before bothering to look for newline There's no valid manifest that would have no characters before the NUL byte on a line, and this fixes some erratic timeouts in the fuzzer. Differential Revision: https://phab.mercurial-scm.org/D5256

revlog: replace PyInt_AS_LONG with a more portable helper function PyInt_AS_LONG disappears on Python, and our previous #define was producing some problems on Python 3. Let's give up and make an inline helper function that makes this more sane. Differential Revision: https://phab.mercurial-scm.org/D5235

help: document weird behavior of uisetup() While refactoring ui.log() API, it was really annoying that uisetup() is actually an extsetup() the phase 1. Let's document that. I'm planning to add another uisetup() which is called per ui instance, though I can't think of a good name for it.

help: merge section about uisetup() and extsetup() They are technically the same callback, called only once per process. The section name "ui setup" is confusing, so shouldn't be used.
