This commit puts the native-tls crate behind a feature. The feature
is off-by-default in the tor-rtcompat crate, but can be enabled
either from arti or arti-client.
There is an included script that I used to test that tor-rtcompat
could build and run its tests with all subsets of its features.
Closes#300
Having separate types here doesn't justify the (very limited)
benefit of distinguishing between the case where we have created an
executor that we own and the case where we have a handle to an
already-running tokio executor.
Part of #301.
This is based on @janimo's approach in !74, but diverges in a few
important ways.
1. It assumes that something like !251 will merge, so that we can
have separate implementations for native_tls and rustls compiled
at the same time.
2. It assumes that we can implement this for the futures::io traits
only with no real penalty.
3. It uses the `x509-signature` crate to work around the pickiness of
the `webpki` crate. If webpki eventually solves their
[bug 219](https://github.com/briansmith/webpki/issues/219), we
can remove a lot of that workaround.
Closes#86.
The docs even say this is about stream.
As @nickm writes in
https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/252#note_2771289
we generally call end-to-end connections that are tunneled over Tor
"Streams" to distinguish them from everything else in the Tor
protocols that could possibly be called a "Connection".
That seems to apply here too.
This is totally not just an exercise to get combined test coverage
for tor-circmgr over 90% because I needed something to do that
wouldn't distract anybody else. :)
Since it implements a "<=" type relationship, it should be called
"at_least_as_permissive_as()." Since it's a crate-private function,
the long name isn't too bad.
There's some kind of bug in nightly that (for me) keeps grcov from
generating correct results. Instead, it misses some crates entirely.
No trouble, though: I can just use an older nightly until they get
this issue fixed!
This patch makes using a different version of nightly possible with
a new RUST_COVERAGE_TOOLCHAIN environment variable.
In the usual case, set_isolation_group is awkward.
This is perhaps slightly duplicative with TorClient::isolated_client().
If so then perhaps the *latter* should be abolished.
We're soon going to have our different Runtime types be built as
CompoundRuntime instances. We don't want to expose that detail,
though, so we'll use this macro to make them implement the right
traits.
This type can solve two problems at once.
First, it lets users replace parts of an existing runtime
implementation without replacing the whole thing. For example, you
can use it to override your TcpProvider implementation to solve
problems like #235.
Second, we can use it internally to tor-rtcompat to define Runtimes
piece-by-piece. Mostly we'll use this to separate our Tls
implementations from our implementations of the rest of the Runtime.
