We need a type that holds a rend_handshake::IntroRequest object
internally, but where we don't materialize that object from the
Introduce2 message inside the MsgHandler, since that's more crypto
than we want to put in that task.
This duplicates some code from hsclient as noted in the comments;
it might be good to reduce this, but the remaining nontrivial
duplication is small, and the logic flow is slightly different
because of the two-step process.
This code has most of what we need to go from an INTRODUCE2 message
we've just received to the point where we've connected to the
rendezvous point and we're waiting for a stream of BEGIN messages.
Unfinished pieces are marked with TODO HSS.
Most of #980.
This should be enough now to establish real introduction points,
though there is still a lot of work to do. Part of #976.
This has been rebased and edited to incorporate discussions from
!1465.
These crates are at version 0.x.y, so we don't need to distinguish
new-feature changes from other changes:
```
tor-basic-utils
fs-mistrust
tor-error
tor-geoip
tor-checkable
tor-linkspec
tor-netdoc
tor-netdir
tor-persist
tor-ptmgr
tor-hsservice
```
This crate has a breaking change, but only when the semver-breaking
feature `experimental-api` is enabled:
```
tor-config
```
This crate is at version 1.x.y, but has no new public APIs, and
therefore does not need a minor version bump:
```
arti
```
These crates had first-order breaking changes:
```
retry-error
tor-keymgr
tor-proto
tor-hsclient
tor-rtmock
```
Additionally, these broke because they re-exposed RetryError:
```
tor-circmgr
```
Additionally, these broke because they may re-expose something from
tor-proto:
```
arti-client
tor-chanmgr
tor-dirclient
tor-dirmgr
tor-guardmgr
```
Additionally, these broke for other fiddly reasons:
`tor-ptmgr` implements traits from tor-chanmgr, which has a breaking
change above.
`arti-hyper` exposes types from arti-client in its API.
Done with the commands below.
The following crates have had various changes, and should get a
patchlevel bump. Since they are pre-1.0, we do not need to
distinguish new APIs from other changes.
```
cargo set-version --bump patch -p arti-client
cargo set-version --bump patch -p safelog
cargo set-version --bump patch -p tor-bytes
cargo set-version --bump patch -p tor-cert
cargo set-version --bump patch -p tor-circmgr
cargo set-version --bump patch -p tor-config
cargo set-version --bump patch -p tor-consdiff
cargo set-version --bump patch -p tor-dirclient
cargo set-version --bump patch -p tor-dirmgr
cargo set-version --bump patch -p tor-error
cargo set-version --bump patch -p tor-hsservice
cargo set-version --bump patch -p tor-linkspec
cargo set-version --bump patch -p tor-llcrypto
cargo set-version --bump patch -p tor-netdir
cargo set-version --bump patch -p tor-netdoc
cargo set-version --bump patch -p tor-proto
cargo set-version --bump patch -p tor-rpcbase
cargo set-version --bump patch -p tor-socksproto
```
This crate has new features, but no new non-experimental Rust APIs.
So even though it is post-1.0, it gets a patchlevel bump.
```
cargo set-version --bump patch -p arti
```
We need the fix from [82d69902], which first appeared in async-trait
version 1.54. (Technically we only need this fix in tor-hsclient,
but we may as well update our minimal async-trait version everywhere.)
[82d69902]: 82d6990253
This does the following:
- Gives every crate a `full`.
- Cause every `full` to depend on `full` from the lower-level
crates.
- Makes every feature listed _directly_ in `experimental` depend
on `__is_experimental`.
These crates had no changes until just a moment ago. But since
we updated the versions on some of their dependents, they have now
changed themselves. Thus they get patchlevel bumps.
```
tor-rtmock
tor-protover
tor-socksproto
tor-consdiff
tor-chanmgr
tor-dirclient
tor-hsservice
```
For these crates, the changes are nontrivial, so we
_do_ bump the versions on which their dependent crates depend.
Fortunately, since they are all pre-1.0, we don't need to
distinguish semver-additions from other changes. (Except for arti,
which _is_ post-1.0, but gets a patchlevel bump anyway.)
These are unstable crates with breaking changes:
```
tor-hscrypto
tor-hsclient
```
These have new or extended APIs:
```
safelog
tor-bytes
tor-cell
tor-linkspec
tor-llcrypto
tor-proto
tor-cert
arti-client
```
These have new unstable APIs or features:
```
tor-netdoc
tor-circmgr (also broke some unstable APIs)
arti (is post-1.0)
```
These have bugfixes only:
```
caret
tor-dirmgr
```
These crates have had small code changes, but no API additions:
tor-config
tor-socksproto
tor-cert
tor-chanmgr
tor-ptmgr
tor-guardmgr
tor-circmgr
tor-dirclient
tor-dirmgr
arti
tor-hsservice
tor-congestion
These crates have had API extensions:
fs-mistrust
tor-llcrypto
tor-bytes
tor-checkable
tor-linkspec
tor-netdoc
tor-persist
arti-client
These are API breaks, but the crates themselves are currently
100% experimental, so there's no need to bump the minor versions
according to our semver rules.
These changes influence behavior, but not effect compatibility.
(If I messed up, and any crate except for `arti` has non-breaking
API changes, that's still fine, since they are all version
0.x.)
