Prompted by clippy::needless_question_mark. Sometimes Ok(r?) is
needed to do automatic error conversion. I assume the lint checks for
that. Anyway, in these cases it's not needed.
tor-netdir needs to bump because tor-netdoc bumped, even though
there were no other changes in tor-netdir. Whoops.
tor-guardmgr needs to bump because it already published, with the
older tor-netdir.
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
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.
I found these versions empirically, by using the following process:
First, I used `cargo tree --depth 1 --kind all` to get a list of
every immediate dependency we had.
Then, I used `cargo upgrade --workspace package@version` to change
each dependency to the earliest version with which (in theory) the
current version is semver-compatible. IOW, if the current version
was 3.2.3, I picked "3". If the current version was 0.12.8, I
picked "0.12".
Then, I used `cargo +nightly upgrade -Z minimal-versions` to
downgrade Cargo.lock to the minimal listed version for each
dependency. (I had to override a few packages; see .gitlab-ci.yml
for details).
Finally, I repeatedly increased the version of each of our
dependencies until our code compiled and the tests passed. Here's
what I found that we need:
anyhow >= 1.0.5: Earlier versions break our hyper example.
async-broadcast >= 0.3.2: Earlier versions fail our tests.
async-compression 0.3.5: Earlier versions handled futures and tokio
differently.
async-trait >= 0.1.2: Earlier versions are too buggy to compile our
code.
clap 2.33.0: For Arg::default_value_os().
coarsetime >= 0.1.20: exposed as_ticks() function.
curve25519-dalek >= 3.2: For is_identity().
generic-array 0.14.3: Earlier versions don't implement
From<&[T; 32]>
httparse >= 1.2: Earlier versions didn't implement Error.
itertools at 0.10.1: For at_most_once.
rusqlite >= 0.26.3: for backward compatibility with older rustc.
serde 1.0.103: Older versions break our code.
serde_json >= 1.0.50: Since we need its Value type to implement Eq.
shellexpand >= 2.1: To avoid a broken dirs crate version.
tokio >= 1.4: For Handle::block_on().
tracing >= 0.1.18: Previously, tracing_core and tracing had separate
LevelFilter types.
typenum >= 1.12: Compatibility with rust-crypto crates
x25519-dalek >= 1.2.0: For was_contributory().
Closes#275.
We are going to get rid of the Arc. Happily there is an id which is
always constructed uniquely and preserved by clone.
(auto-deref lets us make the function take &Self instead of &Arc)

This is a method, so the resolution is automatic. It's not clear to
me why this was written out this way, given that extend_ntor is right
above.

This closes arti#256. It makes our behavior match Tor's more closely,
though it has a simpler implementation than Tor. I think that the extra
complexity in Tor's logic is because we used to record timeouts in
the histogram as well as in the success/failure log.
The implementations of `Add` / `Sub` (et al.) on `std::time::Instant`
can panic if the underlying OS structure can't represent the result
(like arti#266). Use Instant::checked_add and print a warning instead,
to prevent panicking.
Also, we now add instead of subtracting; I suspect it's reasonable that
you might not be able to go backward past the first `Instant` created on
some platforms, but going *forward* should probably work?
IIUC, these anticipatd a need to store min_exit_circs_per_port in
CircMgr. But the current design, where it goes into preemptive.rs and
thence to usage, seems to work fine.
