smartset: convert set to list lazily
If the caller only wants to construct a baseset via a set, and then do
"__contains__" tests. It's unnecessary to initialize the list.
Testing on my unfiltered hg-committed repo where len(draft()) is 2600, this
patch shows about 6% improvement on set intensive queries:
Before:
$ for i in `seq 5`; hg perfrevset 'draft() & draft() & draft() & draft()'
! wall 0.001196 comb 0.000000 user 0.000000 sys 0.000000 (best of 2011)
! wall 0.001191 comb 0.000000 user 0.000000 sys 0.000000 (best of 2099)
! wall 0.001186 comb 0.010000 user 0.010000 sys 0.000000 (best of 1953)
! wall 0.001182 comb 0.000000 user 0.000000 sys 0.000000 (best of 2135)
! wall 0.001193 comb 0.000000 user 0.000000 sys 0.000000 (best of 2177)
After:
$ for i in `seq 5`; hg perfrevset 'draft() & draft() & draft() & draft()'
! wall 0.001128 comb 0.000000 user 0.000000 sys 0.000000 (best of 2247)
! wall 0.001119 comb 0.000000 user 0.000000 sys 0.000000 (best of 2317)
! wall 0.001115 comb 0.000000 user 0.000000 sys 0.000000 (best of 2244)
! wall 0.001131 comb 0.000000 user 0.000000 sys 0.000000 (best of 2093)
! wall 0.001124 comb 0.000000 user 0.000000 sys 0.000000 (best of 2134)
It could have bigger impact on larger sets in theory.
