2021-10-20relay: Overload state on DNS timeout is now X% over Y secsDavid Goulet
With this commit, we will only report a general overload state if we've seen more than X% of DNS timeout errors over Y seconds. Previous behavior was to report when a single timeout occured which is really too small of a threshold. The value X is a consensus parameters called "overload_dns_timeout_scale_percent" which is a scaled percentage (factor of 1000) so we can represent decimal points for X like 0.5% for instance. Its default is 1000 which ends up being 1%. The value Y is a consensus parameters called "overload_dns_timeout_period_secs" which is the time period for which will gather DNS errors and once over, we assess if that X% has been reached ultimately triggering a general overload signal.

2021-03-18Terminate rep_hist_get_overload_stats_lines() with an NL.tor-0.4.6.1-alphaNick Mathewson
We use it in router.c, where chunks are joined with "", not with NL... so leaving off the terminating NL will lead to an unparseable extrainfo. Found by toralf. Bug not in any released Tor.

2021-02-19hs: Remove v2 statsDavid Goulet
We still keep v2 rendezvous stats since we will allow them until the network has entirely phased out. Related to #40266 Signed-off-by: David Goulet <dgoulet@torproject.org>
2020-11-23Revert HSv3 stats string formatting to its old %u self.George Kadianakis
The rest of rephist.c is doing the same kind of unsigned casting. For example see rep_hist_format_buffer_stats() and rep_hist_format_exit_stats(). The previous switch to %ld made Appveyor fail: https://ci.appveyor.com/project/torproject/tor/builds/36118502

These are logically independent from the rest of rephist, and make more sense in isolation. The next patch will rename them too.

It differs from the rest of the rephist code in that it's actually necessary for Tor to operate, so it should probably go somewhere else. I'm not sure where yet, so I'll leave it in the same directory, but give it its own file.

2018-07-05Move literally everything out of src/orNick Mathewson
This commit won't build yet -- it just puts everything in a slightly more logical place. The reasoning here is that "src/core" will hold the stuff that every (or nearly every) tor instance will need in order to do onion routing. Other features (including some necessary ones) will live in "src/feature". The "src/app" directory will hold the stuff needed to have Tor be an application you can actually run. This commit DOES NOT refactor the former contents of src/or into a logical set of acyclic libraries, or change any code at all. That will have to come in the future. We will continue to move things around and split them in the future, but I hope this lays a reasonable groundwork for doing so.
