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`.
Previously, we only accepted an OwnedCircTarget, which would have
kept us from getting a circuit that was aimed at a specialized
CircTarget that gave us LinkSpecs in a raw order.
In one case, we use WeightRole::Exit on circuits that can't
actually be used to exit. This commit adds a comment to explain
why, so that we don't wonder about it in the future, and we have
some indication of whether it's still appropriate.
Closes#785
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
```
We now have support for a pool of pre-build circuits that we can use
for HS-related purposes, and we take circuits from this pool as
needed.
Nothing populates or cleans the circuit pool yet.
Abolish CircMgr::get_or_launch_onion_client and everything to support
it. We have decided that `.onion` diversion ccan't/shouldn't occur in
tor-circmgr. Probably, it should occur much higher up - arti-client
maybe - since it will sometimes need ambient authority (KS_hsc_*).
Now all knowledge of HS connections is in tor-hsclient. This
gets rid of a layering inversion and the trait needed for tor-circmgr
to do the upcall to tor-hsclient.
*If* we're going to retain any HS knowledge in circmgr, it definitely
doesn't need to know about per-operation client secrets.
(Maybe there might be ambient secrets, used for .onion diversion, but
they don't need to be in this API.)
Otherwise there has to be a state entry in the circmgr *and* a state
entry in the hs connector, for every HS. This division of
responsibilit will be confusing.
The HS code will then be more completely just a layer on top of circmgr.
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.)
Clippy now complains about `let _ = (expr_producing_a_future);`,
which is probably smart, since maybe you wanted to await that future
and ignore the result. So it seems that the right way to get rid of
an unwanted Receiver is now to drop it explicitly.
