And `failedConnectionCount`.
Convert the `int` / `uint` to `atomic.Int32` / `atomic.Uint32`.
The race was discovered by running a proxy with the `-race` flag.
For the summary log and for Prometheus metrics.
Log output example:
> In the last 1h0m0s, there were 7 completed successful connections. 2 connections failed. Traffic Relayed ↓ 321 KB (0.10 KB/s), ↑ 123 KB (0.05 KB/s).
Introduces the option `-log-local-time` which switches to local time
for logging instead of using UTC. Also if this option is applied, a message
is being output to the log on startup about the usage of local time
to draw attention, so the user/operator can take care of anonymity in case
the logs are going to be shared.
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
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.
