David Fifield	234d9cb11c	Link a section in the pion/webrtc@3.0.0 release notes.	2023-11-21 01:27:09 +00:00
Cecylia Bocovich	b3b0d3b5dd	Document that prometheus transfer metrics are in KB	2023-11-20 10:40:34 -05:00
Cecylia Bocovich	648609dbea	Refactor disabling the stats logger ... Have Snowflake proxy periodically collect throughput stats even if the stats logger is disabled so that it can be handled by the prometheus metrics.	2023-10-31 13:15:52 -04:00
Cecylia Bocovich	22d9381d9d	Update prometheus metrics to use new EventOnProxyStats	2023-10-31 13:11:38 -04:00
Cecylia Bocovich	caa2b36463	Process and properly log connection closure stats	2023-10-31 10:02:31 -04:00
Cecylia Bocovich	5c5eb2c339	Modify EventOnProxyStats to include summary data	2023-10-30 12:42:45 -04:00
Cecylia Bocovich	018bbd6d65	Proxy stats log only what occurred that time interval ... Modify the periodic stats output by standalone snowflake proxies to only include the data transferred during the time interval being logged. This is an improvement of previous behaviour that logged the total data transferred by all proxy connections that were closed within the time interval being logged.. Closes #40302: https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40302	2023-10-30 12:42:45 -04:00
Cecylia Bocovich	354cb65432	Move creation of periodic stats task inside proxy library ... This adds a new type of SnowflakeEvent. EventOnProxyStats is triggered by the periodic task run at SummaryInterval and produces an event with a proxy stats output string.	2023-10-30 12:42:45 -04:00
Cecylia Bocovich	83a7422fe6	Zero bytesSyncLogger stats after reading them ... This also makes the call to GetStat() more thread safe.	2023-10-30 12:42:45 -04:00
Cecylia Bocovich	939062c7dd	Remove ThroughputSummary from bytesLogger ... This was leftover from when we used to log the total throughput of connections when they close. It should be removed for privacy reasons as mentioned in https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40079	2023-10-30 12:42:45 -04:00
KokaKiwi	7142fa3ddb	fix(proxy): Correctly close connection pipe when dealing with error	2023-10-12 15:52:43 +01:00
WofWca	a615e8b1ab	fix(proxy): remove _potential_ deadlock ... The `dc.Send()` should increase the `bufferedAmount` value, so there is no need to add the message length a second time. Also replace GT with GE, for the case where `BufferedAmountLowThreshold === maxBufferedAmount` Currently the deadlock cannot happen because `maxBufferedAmount` and `BufferedAmountLowThreshold` are too far apart, in fact the former is 2x the latter.

Tommaso Gragnato	9ce1de4eee	Use Pion's Setting Engine to reduce Multicast DNS noise ... https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40123 The purpose of the patch is to prevent Pion from opening the mDNS port, thus preventing snowflake from directly leaking .local candidates. What this doesn't prevent is the resolution of .local candidates once they are passed on to the system DNS.	2022-09-26 08:52:23 -07:00
