We want the set of identities supported by a relay to be extensible
in the future with minimal fuss; we'd also like to make working
with these ID sets more convenient. To handle that, this commit
adds a new trait for "Something that has the same IDs as a relay"
and a new object for "an owned representation of a relay's IDs."
This commit introduces a similar trait for "Something with a list of
SocketAddr, like a relay has." There's no owned equivelent for
that, since Vec<SocketAddr> is already a thing.
Closes#428.
Do _not_ bump the dependency versions on crates that have had no
changes since arti 0.0.5, since those crates do not depend on the
new APIs.
```
cargo set-version -p tor-basic-utils --bump patch
cargo set-version -p tor-llcrypto --bump patch
git restore crates/tor-checkable
git restore crates/tor-consdiff
git restore crates/tor-rtmock
```
This performs the transitive closure of the last operation:
everything that depends on a crate with a breaking change gets the
version which it depends on bumped.
```
cargo set-version -p tor-proto --bump minor
cargo set-version -p tor-netdoc --bump minor
cargo set-version -p arti-hyper --bump minor
cargo set-version -p arti-bench --bump minor
cargo set-version -p arti-testing --bump minor
cargo set-version -p tor-config --bump minor
```
This change was a bit annoying, since most of this code _can't_ fail,
and so the only reasonable response is to wrap the input in an
internal error... except for one case where we're actually encoding
a caller-provided message, so we _do_ want to wrap the EncodeError
from tor_bytes.
This comprises four renames:
```
write_onto -> write_onto_infallible
write_into -> write_into_infallible
write -> write_infallible
writer_and_consume -> write_and_consume_infallible.
```
The rest of this branch will be concerned with replacing these
`_infallible` methods with ones that return a `Result`. This is
part of #513.
This implements a higher-level API for the ntor v3 handshake, in line
with that exposed by the ntor handshake. It does not, however, use the
existing `ClientHandshake` trait, due to fundamental differences in the
handshakes (namely, that the v3 handshake can include some additional
extra extension data).
Currently, the higher-level API assumes circuit extension, and copies
the (undocumented!) magic verification string from c-tor that indicates
this usage.
A rudimentary set of functions for serializing and deserializing
extensions to be sent with the handshake is also included, implementing
the protocol in proposal 332 § A.2. Currently, it only implements the
congestion control extensions specified in proposal 324 § 10.3.
part of arti#88
- arti#448 and arti!607 highlight an issue with upgrading `rsa`: namely,
the `x25519-dalek` version previously used has a hard dependency on
`zeroize` 1.3, which creates a dependency conflict.
- However, `x25519-dalek` version `2.0.0-pre.1` relaxes this dependency.
Reviewing the changelogs, it doesn't look like that version is
substantially different from the current one at all, so it should be
safe to use despite the "prerelease" tag.
- The new `x25519-dalek` version also bumps `rand_core`, which means we
don't have to use the RNG compat wrapper in `tor-llcrypto` as much.
closes arti#448
Found these by disabling the nightly dbg macro special case. Now, we
have a mechanism for globally adding suppressions to tests, we can use
that instead.
Some of these were for decoding particular objects (we now say
what kind of objects), and some were unrelated tor_cert errors that
for some reason we had shoved into a tor_bytes::Error.
There is now a separate tor_cert::CertError type, independent from
tor_cert's use of `tor_bytes::Error` for parsing errors.
According to doc/Errors.md, and in keeping with current best
practices, we should not include display an error's `source()` as
part of that error's display method. Instead, we should let the
caller decide to call source() and display that error in turn.
Part of #323.
The "full" feature is a catch-all for all features, _except_:
* Those that select a particular implementation (like
tor-llcrypto/with-openssl) or build flag (like "static")
* Those that are experimental or unstable (like "experimental-api")
* Those that are testing-only.
