Test order of revisions in compound expression
----------------------------------------------

The general rule is that only the outermost (= leftmost) predicate can
enforce its ordering requirement. The other predicates should take the
ordering defined by it.

 'A & B' should follow the order of 'A':

  $ log '2:0 & 0::2'
  2
  1
  0

 'head()' combines sets in right order:

  $ log '2:0 & head()'
  2
  1
  0

 'x:y' takes ordering parameter into account:

  $ try -p optimized '3:0 & 0:3 & not 2:1'
  * optimized:
  (difference
    (and
      (range
        (symbol '3')
        (symbol '0'))
      (range
        (symbol '0')
        (symbol '3')))
    (range
      (symbol '2')
      (symbol '1')))
  * set:
  <filteredset
    <filteredset
      <spanset- 0:4>,
      <spanset+ 0:4>>,
    <not
      <spanset+ 1:3>>>
  3
  0

 'a + b', which is optimized to '_list(a b)', should take the ordering of
 the left expression:

  $ try --optimize '2:0 & (0 + 1 + 2)'
  (and
    (range
      (symbol '2')
      (symbol '0'))
    (group
      (or
        (list
          (symbol '0')
          (symbol '1')
          (symbol '2')))))
  * optimized:
  (and
    (range
      (symbol '2')
      (symbol '0'))
    (func
      (symbol '_list')
      (string '0\x001\x002')))
  * set:
  <filteredset
    <spanset- 0:3>,
    <baseset [0, 1, 2]>>
  2
  1
  0

 'A + B' should take the ordering of the left expression:

  $ try --optimize '2:0 & (0:1 + 2)'
  (and
    (range
      (symbol '2')
      (symbol '0'))
    (group
      (or
        (list
          (range
            (symbol '0')
            (symbol '1'))
          (symbol '2')))))
  * optimized:
  (and
    (range
      (symbol '2')
      (symbol '0'))
    (or
      (list
        (range
          (symbol '0')
          (symbol '1'))
        (symbol '2'))))
  * set:
  <filteredset
    <spanset- 0:3>,
    <addset
      <spanset+ 0:2>,
      <baseset [2]>>>
  2
  1
  0

 '_intlist(a b)' should behave like 'a + b':

  $ trylist --optimize '2:0 & %ld' 0 1 2
  (and
    (range
      (symbol '2')
      (symbol '0'))
    (func
      (symbol '_intlist')
      (string '0\x001\x002')))
  * optimized:
  (andsmally
    (range
      (symbol '2')
      (symbol '0'))
    (func
      (symbol '_intlist')
      (string '0\x001\x002')))
  * set:
  <filteredset
    <spanset- 0:3>,
    <baseset+ [0, 1, 2]>>
  2
  1
  0

  $ trylist --optimize '%ld & 2:0' 0 2 1
  (and
    (func
      (symbol '_intlist')
      (string '0\x002\x001'))
    (range
      (symbol '2')
      (symbol '0')))
  * optimized:
  (and
    (func
      (symbol '_intlist')
      (string '0\x002\x001'))
    (range
      (symbol '2')
      (symbol '0')))
  * set:
  <filteredset
    <baseset [0, 2, 1]>,
    <spanset- 0:3>>
  0

 '_hexlist(a b)' should behave like 'a + b':

  $ trylist --optimize --bin '2:0 & %ln' `hg log -T '{node} ' -r0:2`
  (and
    (range
      (symbol '2')
      (symbol '0'))
    (func
      (symbol '_hexlist')
      (string '*'))) (glob)
  * optimized:
  (and
    (range
      (symbol '2')
      (symbol '0'))
    (func
      (symbol '_hexlist')
      (string '*'))) (glob)
  * set:
  <filteredset
    <spanset- 0:3>,
    <baseset [0, 1, 2]>>
  2
  1
  0

  $ trylist --optimize --bin '%ln & 2:0' `hg log -T '{node} ' -r0+2+1`
  (and
    (func
      (symbol '_hexlist')
      (string '*')) (glob)
    (range
      (symbol '2')
      (symbol '0')))
  * optimized:
  (andsmally
    (func
      (symbol '_hexlist')
      (string '*')) (glob)
    (range
      (symbol '2')
      (symbol '0')))
  * set:
  <baseset [0, 2, 1]>
  0
  2
  1

 '_list' should not go through the slow follow-order path if order doesn't
 matter:

  $ try -p optimized '2:0 & not (0 + 1)'
  * optimized:
  (difference
    (range
      (symbol '2')
      (symbol '0'))
    (func
      (symbol '_list')
      (string '0\x001')))
  * set:
  <filteredset
    <spanset- 0:3>,
    <not
      <baseset [0, 1]>>>
  2

  $ try -p optimized '2:0 & not (0:2 & (0 + 1))'
  * optimized:
  (difference
    (range
      (symbol '2')
      (symbol '0'))
    (and
      (range
        (symbol '0')
        (symbol '2'))
      (func
        (symbol '_list')
        (string '0\x001'))))
  * set:
  <filteredset
    <spanset- 0:3>,
    <not
      <baseset [0, 1]>>>
  2

 because 'present()' does nothing other than suppressing an error, the
 ordering requirement should be forwarded to the nested expression

  $ try -p optimized 'present(2 + 0 + 1)'
  * optimized:
  (func
    (symbol 'present')
    (func
      (symbol '_list')
      (string '2\x000\x001')))

      (symbol 'present')
      (or

          (symbol '0')
          (symbol '1')
          (symbol '2')))))

 'reverse()' should take effect only if it is the outermost expression:

      (symbol '2'))
    (func
      (symbol 'reverse')

topographical sorting can't be combined with other sort keys, and you can't
use the topo.firstbranch option when topo sort is not active:

  $ hg log -r 'sort(all(), user, topo.firstbranch=book1)'
