manifest: use custom C implementation of lazymanifest
This version is actually lazy, unlike the pure-python version. The
latter could stand to be optimized if anyone actually wants to use it
seriously. I put no work into it.
Before any of my related changes on mozilla-central:
perfmanifest tip
! wall 0.268805 comb 0.260000 user 0.260000 sys 0.000000 (best of 37)
perftags
! result: 162
! wall 0.007099 comb 0.000000 user 0.000000 sys 0.000000 (best of 401)
perfstatus
! wall 0.415680 comb 0.420000 user 0.260000 sys 0.160000 (best of 24)
hgperf export tip
! wall 0.142118 comb 0.140000 user 0.140000 sys 0.000000 (best of 67)
after all of my changes on mozilla-central:
./hg:
perfmanifest tip
! wall 0.232640 comb 0.230000 user 0.220000 sys 0.010000 (best of 43)
perftags
! result: 162
! wall 0.007057 comb 0.010000 user 0.000000 sys 0.010000 (best of 395)
perfstatus
! wall 0.415503 comb 0.420000 user 0.280000 sys 0.140000 (best of 24)
hgperf export tip
! wall 0.025096 comb 0.030000 user 0.030000 sys 0.000000 (best of 102)
so it's no real change in performance on perf{manifest,tags,status},
but is a huge win on 'hgperf export tip'.
There's a little performance work that could still be done here:
fastdelta() could be done significantly more intelligently by using
the internal state of the lazymanifest type in C, but that seems like
good future work.
