encoding: change jsonmap to a list indexed by code point This is slightly faster and convenient to implement a paranoid escaping. $ python -m timeit \ -s 'from mercurial import encoding; data = str(bytearray(xrange(128)))' \ 'encoding.jsonescape(data)' original: 100000 loops, best of 3: 15.1 usec per loop this patch: 100000 loops, best of 3: 13.7 usec per loop

update: change default destination to tipmost descendant (issue4673) (BC) Bare 'hg update' now brings you to the tipmost descendant (on the same branch). Leaving the user on the same topological branch. The previous behavior, updating to the tipmost changeset on the same branch could lead to jump from a topological branch to another. This was confusing and impractical. As the only conceivable reason for the old behavior have been address by the recently introduce message about other heads, we can "safely" change this behavior All test changes have been reviewed and seen a valid consequences.

test: drop useless --update flag in issue1502 tests The --update is unrelated to the test and has no effect as it fails anyway. Dropping it reduces the noise in the coming change in default destination for update.
