Rename "deletable" to "obsolete".
Simplify function structure.
Report errors from `metadata()` and `modified()`.
Don't claim that we're going to delete something unless we are.
Comment about making CUTOFF configurable.
Rather than running preemptive circuit construction every 10
seconds, we change it to back off when it is "failing". (We define
"failing" as creating no new circuits, and as giving at least one
error.)
This change means that we'll have one less reason to hammer the
network when our connectivity is failed for some reason.
Closes#437.
Part of #329.
This feature is similar to ChanProvenance from ChanMgr, except that
we don't yet need to report it outside the crate. I'm going to use
it to distinguish newly created circuits from existing circuits in
the preemptive circuit builder.
Instead of just having a function that recalculates the latest clock
skew, instead recalculate the clock skew when it may have changed,
and notify other processes via a postage::watch.
Apparently on OSX you are not allowed to construct an Instant that is a
long time before the time when the test is running.
Also, fix the length of a year in this test.
This time, our estimator discards outliers, takes the mean of what's
left, and uses the standard deviation to try to figure out how
seriously to take our report of skew/not-skew.
These estimates are still not actually used.
Fortunately, we don't need a separate type here: authenticated
clock skew can only come attached to a `tor_proto::Error`.
We also remove skew from `tor_proto::Error::HandshakeCertsExpired`,
since it would now be redundant.
of a channel.
At first I wanted to have this information not be a part of channels
at all, but it is a fairly tiny amount of data, and the alternatives
are pretty crufty.
Upstream 0.8.2 has broken compilation with Rust 1.53; versions
0.8.{0,1} have been yanked.
Possibly by the time the next arti version comes out, they'll have
fixed this situation, or we'll have upgraded our MSRV.
Upstream issue at https://github.com/Nugine/rlimit/issues/42 .
Doing this will make us treat caches that send us these objects as
not-working, and close circuits to them instead of trying over and
over.
The case where we add a document from the cache requires special
handling: it isn't actually a error to find an expired document in
our cache (unless the passage of time itself is erroneous, which is
a debatable proposition at best).
Fixes#431.
