Brad Fitzpatrick db2cc393af util/dirwalk, metrics, portlist: add new package for fast directory walking ... This is similar to the golang.org/x/tools/internal/fastwalk I'd previously written but not recursive and using mem.RO. The metrics package already had some Linux-specific directory reading code in it. Move that out to a new general package that can be reused by portlist too, which helps its scanning of all /proc files: name old time/op new time/op delta FindProcessNames-8 2.79ms ± 6% 2.45ms ± 7% -12.11% (p=0.000 n=10+10) name old alloc/op new alloc/op delta FindProcessNames-8 62.9kB ± 0% 33.5kB ± 0% -46.76% (p=0.000 n=9+10) name old allocs/op new allocs/op delta FindProcessNames-8 2.25k ± 0% 0.38k ± 0% -82.98% (p=0.000 n=9+10) Change-Id: I75db393032c328f12d95c39f71c9742c375f207a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>		2022-11-05 16:26:51 -07:00
