revset: force ascending order for baseset initialized from a set It is possible to initialize a baseset directly from a set object. However, in this case the iteration order was inherited from the set. Set have undefined iteration order (especially cpython and pypy will have different one) so we should not rely on it anywhere. Therefor we declare the baseset "ascending" to enforce a consistent iteration order. The sorting is done lazily by the baseset class and should have no performance impact when it does not matter. This makes test-revset.t pass with pypy.

revset: stabilize repr of baseset initialized with a set Cpython and pypy have different way to build and order set, so the result of list(myset) is different. We work around this by using the sorted version of the data when displaying a list. This get pypy closer to pass test-revset.t.

dispatch: factor out command failure handling into a function Moving the warning generation to a function allows for wrapping and alternative error handling.

pypy: fix overeager pattern matching on mpatchError Pypy have difference in error reporting.

mpatch: unify mpatchError (issue5182) The pure version was mpatch was throwing struct.error or ValueError for errors, whereas the C version was throwing an "mpatch.mpatchError". Introducing an mpatch.mpatchError into pure and using it consistently is fairly easy, but the actual form for it is mercurial.mpatch.mpatchError, so with this commit, we change the C implementation to match the naming convention too.

check-code: reject sed ... \\n This would have caught 142891ab6e89 (fixed by a5a13eeffc59) if repcomment didn't make the content of the perl code opaque to the check.

hideablerevs: expand docstring to warn about possible traps Sean Farley just wasted multiple hours trying to figure out why his code was crashing. We update the docstring to make the constraint clearer.

hghave: replace relative import of docutils.core

tests: make tinyproxy.py not import sys.argv by name

tests: alias ui as uimod in test-walkrepo
