| * | | | chanmgr: Add the code necessary to use SOCKS PTs via a TransportHelperNick Mathewson2022-10-204-5/+254
| | | | | | | | | | | | | | | | | | | | | | | | | This is mostly a matter of encoding parameters in the format used for socks authentication.
| * | | | chanmgr: Begin a socks-client implementation.Nick Mathewson2022-10-203-0/+219
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code is _not_ conditional, since we want to support running with a proxy even if we don't support pluggable transports. We may eventually want to refactor this into a new create.

| * | | tor-linkspec: impl From<&ChanTarget> for OwnedChanTargetIan Jackson2022-10-201-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | This lets us write functions which can either take an existing owned OwnedChanTarget, or copy out of some other kind of ChanTarget passed by reference.
| * | | circmgr: Plumbing for direct to target directory circuitsIan Jackson2022-10-202-2/+29
| | | | | | | | | | | | | | | | | | | | The target is identified by Into<OwnedChanTarget>. We introduce corresponding TargetCircUsage and SupportedCircUsage.
| * | | bridge descriptors: Change types of the descriptor cacheIan Jackson2022-10-201-3/+12
| |/ / | | | | | | | | | | | | | | | | | | Now keyed by Arc<BridgeConfig>, and the values can be errors. Currently there is no implementation so there can't be any errors, but the error enum will become nonempty.

* | chanmgr: Add an error case if a final_attempt neither succeeds or failsNick Mathewson2022-10-182-1/+11
| | | | | | | | | | This can happen in weird corner cases, so it's probably best to report it rather than having an "internal error."
* | Refactor flow control in get_or_launch.Nick Mathewson2022-10-182-54/+97
| | | | | | | | | | | | | | Now, instead of duplicate checks in various cases, we simply go through the loop one last time. This allows us to simplify some of our other logic around here.
* | chanmgr: Split get_or_launch into sub-functions.Nick Mathewson2022-10-181-92/+95
| | | | | | | | | | This function had grown huge and hard to reason about. Before I make it even worse, let's split it up.

* | chanmgr: Remove "Ident" from AbstractChannelNick Mathewson2022-10-185-84/+24
| | | | | | | | | | Thanks to our previous changes, we no longer need this type, or the methods that access it.
* | chanmgr: replace the HashMap<> with a ByRelayIds.Nick Mathewson2022-10-184-312/+312
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is necessary so that we can look up channels (open and pending) by all of the Ids that we know about them. The operations needed here are pretty complex: to get them right, I've replaced most of the accessors on the inner `ChannelMap` with a function that holds the lock while another `FnOnce` is called. This still gets us the invariant that we can't accidentally await while holding the lock on the `ChannelMap`. I've removed the tests for the accessors that are no longer there. There are some subtleties here. Now that we have more than one kind of Id, it's possible to have a partial match. I've tried to explain all these cases in the comments. }
* | proto: Make Channel::reparameterize take &self.Nick Mathewson2022-10-182-2/+3
| | | | | | | | | | | | | | | | | | | | Even though channels are practically changeable, they use locks internally so that you don't need a `&mut Channel` to send or receive traffic. It makes sense for reparameterizing the channel to also use a &self reference. I'll need this so that I can store channels in an `ByRelayIds<>` set, and still invoke their reparameterize methods.
* | chanmgr: Add identities to pending state in map.Nick Mathewson2022-10-182-8/+46
| | | | | | | | | | This will let us migrate from `HashMap<Ed25519Identity, Entry>` to `ByRelayIds<Entry>`.
* | chanmgr: Require HasRelayIds for AbstractChannel::BuildSpecNick Mathewson2022-10-182-24/+50
| | | | | | | | | | | | This is mostly a testing only change for now too, but soon I'll use it to deal with the fact that we need to know the IDs to actually build a channel at all.
* | chanmgr: Require HasRelayIds for AbstractChannel.Nick Mathewson2022-10-182-1/+43
| | | | | | | | | | This is mostly a testing-only change for now, but soon I'll use it so we can have IdMap for our channel map.
* | chanmgr: Remove the Poisoned state from the map type.Nick Mathewson2022-10-182-48/+12
| | | | | | | | | | | | | | | | The `ByRelayIds` type doesn't have a type equivalent to `hash_map::Entry`, since it's a set type rather than a map type. Therefore, the only plausible way to do entry mutation will be to remove the old entry and insert a new one. And so, we no longer need a "poisoned" state.
* | proto: Implement HasRelayIds for Channel.Nick Mathewson2022-10-182-0/+10
| |
* | linkspec: Add ByRelayIds::remove_exact.Nick Mathewson2022-10-181-0/+65
| | | | | | | | | | We need a function to remove an entry if it appears with _exactly_ the same relay Ids, but not otherwise. This method will do that.
* | linkspec: Add an "all_overlapping" accessor to ByRelayIds.Nick Mathewson2022-10-183-1/+117
| | | | | | | | | | | | | | Also, add a few tests for this and the other accessors. We'll need this accessor to find whether we have any channels to _any_ of the identities that we're trying to connect to.

* | Fix deserialize impl for RelayId.Nick Mathewson2022-10-151-1/+1
| | | | | | | | | | | | | | We need to handle String, not just str, since some deserializers have to handle escapes and generate new strings. Found while writing tests; fixes #605.

* chanmgr: Remove RegistryAsFactory.Nick Mathewson2022-10-131-11/+6
| | | | | Since there is no longer a blanket implementation of ChannelFactory for TransportHelper, we no longer need a separate type here.
* ChanMgr: Reorganize factory, builder, transport code.Nick Mathewson2022-10-136-282/+330
| | | | There is no actual code change here: just movement.
* Fix some rustdoc errors.Nick Mathewson2022-10-138-21/+18
| | | | | | In addition to the usual "You named that method wrong!" errors, we have a new rustdoc error that complains about bogus "HTML tags" that are actually unquoted usage of types like `Result<Foo>`.

| * Have ChannelBuilder use TransportHelper.Nick Mathewson2022-10-134-27/+92
| | | | | | | | | | | | This lets us build channels using different TransportHelpers, including the (new) default TransportHelper, which just uses the old connect_to_one() code.
| * Implement ChannelFactory for (a wrapper of) TransportRegistry.Nick Mathewson2022-10-121-1/+23
| | | | | | | | This will let us just have ChanMgr take a `dyn ChannelFactory`.
| * chanmgr: Clean up async-ness on factory types.Nick Mathewson2022-10-122-12/+18
| | | | | | | | | | | | | | | | The traits that launch connections need to be async; the traits that don't, shouldn't be async. Additionally, we need a few more "Sync" annotations here for the futures to work.
| * Rename mgr::ChannelFactory to mgr::AbstractChannelFactoryNick Mathewson2022-10-123-19/+22
| | | | | | | | | | | | | | | | | | This is an internal type (distinct from factory::ChannelFactory) that we use to make the code in `tor_chanmgr::mgr` agnostic about what a channel actually is, and how it is actually launched. Therefore, I'm renaming it and giving better documentation in a couple of places, to prevent confusion.
