revset: avoid O(n) lookup of invalid revision in rev() ba89f7b542c9 was not the final version of that patch. It was really slow because `l not in repo.changelog` iterates revisions up to `l`. Instead, rev() should utilize spanset.__contains__(). revset #0: rev(210000) 0) wall 0.000039 comb 0.000000 user 0.000000 sys 0.000000 (best of 67978) 1) wall 0.002721 comb 0.000000 user 0.000000 sys 0.000000 (best of 1055) 2) wall 0.000059 comb 0.000000 user 0.000000 sys 0.000000 (best of 45599) (0: 3.2-rc, 1: ba89f7b542c9, 2: this patch) Note that the benchmark result described in ba89f7b542c9 is wrong because it is the one of the initial version.

run-tests: output diffs with only forward slashes This removes some gratuitous variance when testing on Windows with test-run-tests.t.

i18n: add hint to digest mismatch message

help/config: fix typo

files: fix example list syntax

parsers: use 'k' format for Py_BuildValue instead of 'n' because Python 2.4 'n' was introduced in Mercurial in 2b5940f64750 and broke Python 2.4 support in mysterious ways that only showed failure in test-glog.t. Py_BuildValue failed because of the unknown format and a TypeError was thrown ... but it never showed up on the Python side and it happily continued processing with wrong data. Quoting https://docs.python.org/2/c-api/arg.html : n (integer) [Py_ssize_t] Convert a Python integer or long integer to a C Py_ssize_t. New in version 2.5. k (integer) [unsigned long] Convert a Python integer or long integer to a C unsigned long without overflow checking. This will use unsigned long instead of Py_ssize_t. That is not a good solution, but good is not an option when we have to support Python 2.4.

rebase: improve base revset performance The old revset had pretty terrible performance on large repositories (12+ seconds). This new revset achieves the same result in only 0.7s. As we improve the underlying revset APIs we can probably get this revset down to 'only(base, dest)::', but at the moment that version still takes 2s.
