tests: use graph log in {latesttag} tests The tests are much easier to read if one does not have to re-read the setup part all the time to understand the graph shape. Differential Revision: https://phab.mercurial-scm.org/D446

demandimport: disable if chg is being used In chg's case, making modules lazily loaded could actually slow down things since chg pre-imports them. Therefore disable demandimport if chg is being used. This is not done by setting `HGDEMANDIMPORT` chg client-side because that has side-effects on child processes (hooks, etc). Differential Revision: https://phab.mercurial-scm.org/D351

demandimport: move HGDEMANDIMPORT test to __init__.py The logic is now shared between demandimport{2,3}. Differential Revision: https://phab.mercurial-scm.org/D445

log: add a "graphwidth" template variable Wrapping text in templates for 'hg log --graph' can't be done very well, because the template doesn't know how wide the graph drawing is. The edge drawing function needs to know the number of lines in the template output, so we need to also determine how wide that drawing would be before we call the edgefn or evaluate the template. This patch makes edgefn compute the graph width and pass it into the template so that we can do something like this: COLUMNS=10 hg log --graph --template "{fill(desc, termwidth - graphwidth)}" @ a a a a | a a a a | a a a a o a a a |\ a a a | | a a a | | a a a Using extensions to do this would be relatively complicated due to a lack of hooks in this area of the code. In the future it may make sense to have a more generic "textwidth" that tells you how many columns you can expect to fill without causing the terminal to wrap your output. I'm not sure there are other situations to motivate this yet, or if it is entirely feasible. Differential Revision: https://phab.mercurial-scm.org/D360

obsmarker: fix precnode deprecation The deprecation message for marker.precnode was wrong. Fix the typo. Differential Revision: https://phab.mercurial-scm.org/D413

obsmarker: precnode was renamed into prednode Update all calls to formatter.write first arguments to remove references to precnode and use prednode consistently everywhere. Differential Revision: https://phab.mercurial-scm.org/D414

revset: mark evolution-related revsets as experimental Differential Revision: https://phab.mercurial-scm.org/D416

push: fix docsstring Seems the code block misses `::`. This patch makes sure `[push]` and `pushvars.server = true` are in two lines. Differential Revision: https://phab.mercurial-scm.org/D411

py3: select input or raw_input by pycompat This seems slightly cleaner.

py3: make encoding.strio() an identity function on Python 2 It's the convention the other encoding.str*() functions follow. To make things simple, this also drops kwargs from the strio() constructor.
