Brad Fitzpatrick	79b7fa9ac3	internal/deephash: hash maps without sorting in the acyclic common case ... Hash and xor each entry instead, then write final xor'ed result. name old time/op new time/op delta Hash-4 33.6µs ± 4% 34.6µs ± 3% +3.03% (p=0.013 n=10+9) name old alloc/op new alloc/op delta Hash-4 1.86kB ± 0% 1.77kB ± 0% -5.10% (p=0.000 n=10+9) name old allocs/op new allocs/op delta Hash-4 51.0 ± 0% 49.0 ± 0% -3.92% (p=0.000 n=10+10) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	cd54792fe9	internal/deephash: add a few more benchmarking map entries ... Typical maps in production are considerably longer. This helps benchmarks more accurately reflect the costs per key vs the costs per map in deephash. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	25df067dd0	all: adapt to opaque netaddr types ... This commit is a mishmash of automated edits using gofmt: gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w . gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w . gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w . gofmt -r 'a.IP.As16 -> a.IP().As16' -w . gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w . gofmt -r 'a.IP.As4 -> a.IP().As4' -w . gofmt -r 'a.IP.String -> a.IP().String' -w . And regexps: \w*(.*)\.Port = (.*) -> $1 = $1.WithPort($2) \w*(.*)\.IP = (.*) -> $1 = $1.WithIP($2) And lots of manual fixups. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	aacb2107ae	all: add extra information to serialized endpoints ... magicsock.Conn.ParseEndpoint requires a peer's public key, disco key, and legacy ip/ports in order to do its job. We currently accomplish that by: * adding the public key in our wireguard-go fork * encoding the disco key as magic hostname * using a bespoke comma-separated encoding It's a bit messy. Instead, switch to something simpler: use a json-encoded struct containing exactly the information we need, in the form we use it. Our wireguard-go fork still adds the public key to the address when it passes it to ParseEndpoint, but now the code compensating for that is just a couple of simple, well-commented lines. Once this commit is in, we can remove that part of the fork and remove the compensating code. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	4 years ago
Brad Fitzpatrick	36a26e6a71	internal/deephash: rename from deepprint ... Yes, it printed, but that was an implementation detail for hashing. And coming optimization will make it print even less. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
