- Avoid memmoving 0 bytes which might lead to compiler warnings.
- Don't require relays to be entry node AND bridge at the same to time to
record clients.
- Fix a memory leak when writing dirreq-stats.
- Don't say in the stats files that measurement intervals are twice as long
as they really are.
- Reduce minimum observation time for requests to 12 hours, or we might
never record usage.
- Clear exit stats correctly after writing them, or we accumulate old stats
over time.
- Reset interval start for buffer stats, too.
This was the only log notice that happened during other
tor invocations, like --verify-config and --list-fingerprint.
Plus, now we think it works, so no need to hear about it.
"Tinytest" is a minimalist C unit testing framework I wrote for
Libevent. It supports some generally useful features, like being able
to run separate unit tests in their own processes.
I tried to do the refactoring to change test.c as little as possible.
Thus, we mostly don't call the tinytest macros directly. Instead, the
test.h header is now a wrapper on tinytest.h to make our existing
test_foo() macros work.
The next step(s) here will be:
- To break test.c into separate files, each with its own test group.
- To look into which things we can test
- To refactor the more fiddly tests to use the tinytest macros
directly and/or run forked.
- To see about writing unit tests for things we couldn't previously
test without forking.
If the networkstatus consensus tells us that we should use a
negative circuit package window, ignore it. Otherwise we'll
believe it and then trigger an assert.
Also, change the interface for networkstatus_get_param() so we
don't have to lookup the consensus beforehand.
A) We were considering a circuit had timed out in the special cases
where we close rendezvous circuits because the final rendezvous
circuit couldn't be built in time.
B) We were looking at the wrong timestamp_created when considering
a timeout.
Don't discard all circuits every MaxCircuitDirtiness, because the
user might legitimately have set that to a very lower number.
Also don't use up all of our idle circuits with testing circuits,
since that defeats the point of preemptive circuits.
We want it to be under our control so it doesn't mess
up initialization. This is likely the cause for
the bug the previous assert-adding commit (09a75ad) was
trying to address.
