Brad Fitzpatrick	3f4a567032	types/strbuilder: add a variant of strings.Builder that uses sync.Pool ... and thus does not need to worry about when it escapes into unprovable fmt interface{} land. Also, add some convenience methods for efficiently writing integers.	4 years ago
Avery Pennarun	af9328c1b7	log rate limiting: reformat limiter messages, and use nonempty burst size. - Reformat the warning about a message being rate limited to print the format string, rather than the formatted message. This helps give a clue what "type" of message is being limited. - Change the rate limit warning to be [RATE LIMITED] in all caps. This uses less space on each line, plus is more noticeable. - In tailscaled, change the frequency to be less often (once every 5 seconds per format string) but to allow bursts of up to 5 messages. This greatly reduces the number of messages that are rate limited during startup, but allows us to tighten the limit even further during normal runtime.

Wendi Yu	0c69b4e00d	Implement rate limiting on log messages (#356 ) Implement rate limiting on log messages Addresses issue #317, where logs can get spammed with the same message nonstop. Created a rate limiting closure on logging functions, which limits the number of messages being logged per second based on format string. To keep memory usage as constant as possible, the previous cache purging at periodic time intervals has been replaced by an LRU that discards the oldest string when the capacity of the cache is reached.

Brad Fitzpatrick	922d9546bf	wgengine: don't allocate so much in userspaceEngine.getStatus It was one of the top garbage producers on my phone. It's slated to be deleted and replaced anyway, but this helps in the meantime. The go.sum changes look scary, but the new dep only adds 240 bytes to the binary. The go.sum noise is just cmd/go being aggressive in including a lot of stuff (which is being fixed in Go 1.15, for what I understand). And I ran a go mod tidy, which added some too. (I had to write a custom wrapper around go mod tidy because this mod tidy normally breaks on tailscale.io/control being missing but referenced in tests) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
