Josh Bleecher Snyder	aa9d7f4665	tstime: add Parse3339B, for byte slices Use go4.org/mem for memory safety. A slight performance hit, but a huge performance win for clients who start with a []byte. The perf hit is due largely to the MapHash call, which adds ~25ns. That is necessary to keep the fast path allocation-free. name old time/op new time/op delta GoParse3339/Z-8 281ns ± 1% 283ns ± 2% ~ (p=0.366 n=9+9) GoParse3339/TZ-8 509ns ± 0% 510ns ± 1% ~ (p=0.059 n=9+9) GoParse3339InLocation-8 330ns ± 1% 330ns ± 0% ~ (p=0.802 n=10+6) Parse3339/Z-8 69.3ns ± 1% 74.4ns ± 1% +7.45% (p=0.000 n=9+10) Parse3339/TZ-8 110ns ± 1% 140ns ± 3% +27.42% (p=0.000 n=9+10) ParseInt-8 8.20ns ± 1% 8.17ns ± 1% ~ (p=0.452 n=9+9) name old alloc/op new alloc/op delta GoParse3339/Z-8 0.00B 0.00B ~ (all equal) GoParse3339/TZ-8 160B ± 0% 160B ± 0% ~ (all equal) GoParse3339InLocation-8 0.00B 0.00B ~ (all equal) Parse3339/Z-8 0.00B 0.00B ~ (all equal) Parse3339/TZ-8 0.00B 0.00B ~ (all equal) name old allocs/op new allocs/op delta GoParse3339/Z-8 0.00 0.00 ~ (all equal) GoParse3339/TZ-8 3.00 ± 0% 3.00 ± 0% ~ (all equal) GoParse3339InLocation-8 0.00 0.00 ~ (all equal) Parse3339/Z-8 0.00 0.00 ~ (all equal) Parse3339/TZ-8 0.00 0.00 ~ (all equal) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

David Anderson	9cd4e65191	smallzstd: new package that constructs zstd small encoders/decoders. It's just a config wrapper that passes "use less memory at the expense of compression" parameters by default, so that we don't accidentally construct resource-hungry (de)compressors. Also includes a benchmark that measures the memory cost of the small variants vs. the stock variants. The savings are significant on both compressors (~8x less memory) and decompressors (~1.4x less, not including the savings from the significantly smaller window on the compression side - with those savings included it's more like ~140x smaller).

Brad Fitzpatrick	e6b84f2159	all: make client use server-provided DERP map, add DERP region support Instead of hard-coding the DERP map (except for cmd/tailscale netcheck for now), get it from the control server at runtime. And make the DERP map support multiple nodes per region with clients picking the first one that's available. (The server will balance the order presented to clients for load balancing) This deletes the stunner package, merging it into the netcheck package instead, to minimize all the config hooks that would've been required. Also fix some test flakes & races.
