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 To keep memory usage as constant as possible, the previous cache purging at periodic time intervals has been replaced by an LRU that discards the oldest string when the capacity of the cache is reached.

Avery Pennarun	9d1f48032a	cmd/tailscale: add --advertise-tags option. ... These will be used for dynamically changing the identity of a node, so its ACL rights can be different from your own.

Brad Fitzpatrick	64334143a1	tsweb: rename Handler to ReturnHandler ... The name's been bugging me for a long time. I liked neither the overlap between tsweb.Handler and http.Handler, nor the name "ServeHTTPErr" which sounds like it's an error being returned, like it's an error handler and not sometimes a happy path.

Avery Pennarun	b4897e7de8	controlclient/netmap: write our own b.ConciseDiffFrom(a) function. ... This removes the need for go-cmp, which is extremely bloaty so we had to leave it out of iOS. As a result, we had also left it out of macOS, and so we didn't print netmap diffs at all on darwin-based platforms. Oops. As a bonus, the output format of the new function is way better. Minor oddity: because I used the dumbest possible diff algorithm, the sort order is a bit dumb. We print all "removed" lines and then print all "added" lines, rather than doing the usual diff-like thing of interspersing them. This probably doesn't matter (maybe it's an improvement).	5 years ago
