Without this, actually building circuits manually is a pain.
This API is behind the `experimental-api` feature, and so it does
not require a semver.md entry.
Try to clarify more that the ChannelUsage is for describing the
usage for one particular channel request, not for the channel as a
whole. This is a potentially confusing point, so we should spell it
out completely.
As a matter of good crypto practice, we shouldn't use
short-circuiting checks to compare keys or key-like objects, since
the amount of time taken by those checks can leak information about
their inputs.
I don't think it's actually _necessary_ to use a constant-time
operation in this case, but let's establish the precedent.
This is a follow-up to !724.
There are some places in the protocol where we have an all-zero RSA
identity that does not truly represent a key, but rather represents
an absent or unknown key. For these, it's better to use
`RsaIdentity::is_zero` instead of manually checking for a set of
zero bytes: it expresses the intent better, and ensures that the
operation is constant-time.
I am deliberately not introducing a more general IsZero trait here,
or implementing is_zero for anything else: This is the only one we
seem to need right now. We can generalize it later if we have to.
This fixes an busy-loop.
When the last `TaskHandle` on a `TaskSchedule` is dropped, the
schedule is permanently canceled: whatever operation it was
scheduling should no longer be performed. But our code was broken:
the `sleep()` and `sleep_until_wallclock()` functions don't verify
whether the handles are dropped or not.
This breakage caused an CPU-eating busy-loop in
`sleep_until_wallclock`.
With this patch, we now return a `Result<(), SleepError>` from these
functions.
Fixes#572.
Because we want to work more on ensuring that our semver stability
story is solid, we are _not_ bumping arti-client to 1.0.0 right now.
Here are the bumps we _are_ doing. Crates with "minor" bumps have
had API breaks; crates with "patch" bumps have had new APIs added.
Note that `tor-congestion` is not bumped here: it's a new crate, and
hasn't been published before.
```
tor-basic-utils minor
fs-mistrust minor
tor-config minor
tor-rtcompat minor
tor-rtmock minor
tor-llcrypto patch
tor-bytes patch
tor-linkspec minor
tor-cell minor
tor-proto minor
tor-netdoc patch
tor-netdir minor
tor-persist patch
tor-chanmgr minor
tor-guardmgr minor
tor-circmgr minor
tor-dirmgr minor
arti-client minor
arti-hyper minor
arti major
arti-bench minor
arti-testing minor
```
Since our last round of releases, these crates have had either
trivial changes, or changes that did not affect their APIs.
Therefore we are bumping their versions, but not changing which
versions of them other crates depend on.
This patch fixes a minor build error where we would call
`compact_home()` on Windows instead of `anonymize_home()` on our PathBuf
instance.
Additionally we change how the `arti_conf` path is constructed such that
we join the individual path components to ensure that no "/" ends up
being present on Windows where path's are separated by "\".

This patch shortens the duration of the `does_not_predict_old_ports`
test in the preemptive module. AppVeyor spawns its VMs/containers per
build, so the `Instant::now()` call returns a value smaller than `60 *
60 + 1` which causes the subtraction to overflow and thus panic.
Thanks to @trinity-1686a for the help here.
