These were mostly releated to the routerinfo_t->node_t conversion.
This once maybe made sense when ExitNodes meant "Here are 3 exits;
use them all", but now it more typically means "Here are 3
countries; exit from there." Using non-Fast/Stable exits created a
potential partitioning opportunity and an annoying stability
problem.
(Don't worry about the case where all of our ExitNodes are non-Fast
or non-Stable: we handle that later in the function by retrying with
need_capacity and need_uptime set to 0.)
The last entry of the *Maxima values in the state file was inflated by a
factor of NUM_SECS_ROLLING_MEASURE (currently 10). This could lead to
a wrong maximum value propagating through the state file history.
When reading the bw history from the state file, we'd add the 900-second
value as traffic that occured during one second. Fix that by adding the
average value to each second.
This bug was present since 0.2.0.5-alpha, but was hidden until
0.2.23-alpha when we started using the saved values.
While doing so, get rid of the now unnecessary function
control_signal_act().
Fixes bug 2917, reported by Robert Ransom. Bugfix on commit
9b4aa8d2ab. This patch is loosely based on
a patch by Robert (Changelog entry).
Instead of answering GETINFO requests about our geoip usage only after
running for 24 hours, this patch makes us answer GETINFO requests
immediately. We still round and quantize as before.
Implements bug2711.
Also, refactor the heck out of the bridge usage formatting code. No
longer should we need to do a generate-parse-and-regenerate cycle to
get the controller string, and that lets us simplify the code a lot.
- Document it in the manpage
- Add a changes entry
- No need to log when it is set: we don't log for other options.
- Use doxygen to document the new flag.
- Test truth of C variables with "if (x)", not "if (x == 1)".
- Simplify a complex boolean expression by breaking it up.
We've got millisecond timers now, we might as well use them.
This change won't actually make circuits get expiered with microsecond
precision, since we only call the expiry functions once per second.
Still, it should avoid the situation where we have a circuit get
expired too early because of rounding.
A couple of the expiry functions now call tor_gettimeofday: this
should be cheap since we're only doing it once per second. If it gets
to be called more often, though, we should onsider having the current
time be an argument again.
