logtoprocess: leverage procutil.shellenviron() to stringify variables (BC) This should make the extension more Py3 friendly. The environment variables of the main process are copied to the dict by shellenviron(). .. bc:: Boolean options passed to the logtoprocess extension are now formatted as ``0`` or ``1`` instead of ``None``, ``False``, or ``True``.

templater: check invalid use of list expression properly (issue5920) The error message is still cryptic, but it should be better.

py3: add b suffix to make sure file is opened in bytes mode Differential Revision: https://phab.mercurial-scm.org/D5263

py3: don't use dict.iterkeys() dict.iterkeys() is not present on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5262

py3: use node.hex(h.digest()) instead of h.hexdigest() hashlib.sha1.hexdigest() returns str on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5261

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.

help: add internals.extensions topic I think it's better to include the API overview in core as we now have the internals section in our help system. Retrieved from the wiki, and formatted as reST. Several wiki links are removed since they are invalid in the help. The sections about example extension are removed at all as they seemed too verbose. https://www.mercurial-scm.org/wiki/WritingExtensions

commandserver: send raw progress information to message channel This is pretty basic implementation to support GUI progress bar.

commandserver: make getpass() request distinct from normal prompt Otherwise, GUI clients would have to parse the prompt text.
