revset: restore order of `or` operation as in Mercurial 2.9 Lazy revset broke the ordering of the `or` revset. We now stop assuming that two ascending revset are combine into an ascending one. Behavior in 3.0: 3:4 or 2:5 == [2, 3, 4, 5] Behavior in 2.9: 3:4 or 2:5 == [3, 4, 2, 5] We are adding a test for it. For unclear reason, the performance `or` revset with expensive filter are getting even worse than they used to be. This is probably caused by extra uncached containment check or iteration. revset #9: author(lmoscovicz) or author(mpm) before) wall 3.487583 comb 3.490000 user 3.490000 sys 0.000000 (best of 3) after) wall 4.481486 comb 4.480000 user 4.470000 sys 0.010000 (best of 3) revset #10: author(mpm) or author(lmoscovicz) before) wall 3.164839 comb 3.170000 user 3.160000 sys 0.010000 (best of 3) after) wall 4.574965 comb 4.570000 user 4.570000 sys 0.000000 (best of 3)
