* tor-rtcompat: Big invasive change adding StreamOps bound everywhere.Gabriela Moldovan2025-01-154-13/+23
| | | | | | This is unfortunately necessary, because after the channel handshake, we need to give the channel reactor a `StreamOps` handle to the underlying stream.
* tor-rtcompat: Add the ability to get a StreamOps handle.Gabriela Moldovan2025-01-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Needed for cases where we wrap an object that implements `StreamOps` in an external type, thereby losing access to the `StreamOps` functionality. For example, during the channel handshake, we `.split()` the stream that implements `StreamOps`, which leaves us with a `SplitSink` and a `SplitStream`, neither of which implement `StreamOps`. Getting a handle to the underlying object that implements `StreamOps` (for example, a file handle) *before* the stream is `.split()` enables us to use `StreamOps` to manipulate the underlying split stream. This commit also introduces a special `UnsupportedStreamOpsHandle`, which is a type that implements `StreamOps`, but always returns an error. This type is meant to simplify error handling and usage, and is meant to be used in cases where `StreamOps` is not supported. TODO: the name of this type is pretty confusing (it's very similar to `UnsupportedStreamOp`, which is an error type), and should probably be renamed to something else (`NoOpStreamOpsHandle`, `BrokenStreamOpsHandle`, `DummyStreamOpsHandle` come to mind...). Note: this changes the `StreamOps` trait to be slightly different from what I originally envisioned in !2660 and #1769
* tor-proto: Add KistParams type built from NetParameters.Gabriela Moldovan2025-01-153-0/+63
| | | | | | | | Note: this commit makes `tor-proto` depend on `tor-netdir` (because it adds a `KistParams` type that is buildable from `NetParameters`, which is defined in `tor-netdir`). Closes #1729

* tor-proto: `Channel::wait_for_close` return success statusSteven Engler2025-01-092-14/+42
| | | | | | This had a TODO about returning a "status indication instead of just ()" so this commit adds some status indication that we can expand later if needed.
* Bump versions of internal arti crates for Arti 1.3.2Nick Mathewson2025-01-071-18/+18
| | | | | | | | | | | | | The affected crates follow our regular versioning. They all get bumped to 0.26.0. Done with ``` for crate in $(./maint/list_crates |grep '^arti-\|tor-' ); do cargo set-version --bump minor -p $crate; done ```

* tor-proto: implement `FusedFuture` for receiver futuresSteven Engler2024-12-101-33/+79
| | | | | | | | I considered just using `FutureExt::fuse`, but that becomes a little annoying since the future type is exposed through `IntoFuture::IntoFuture`, which means `ReceiverFuture` would need to wrap a `Fuse`. I figured it's cleaner just to implement the trait directly.

* tor-proto: update docs on `Channel::reactor_closed_rx`Steven Engler2024-12-101-3/+1
| | | | | This is no longer applicable with the new oneshot broadcast channel design.
* tor-proto: replace oneshot broadcast channelSteven Engler2024-12-103-138/+563
| | | | | The old version had some issues, so this is a rewrite which uses slightly lower level synchronization types (`Mutex` and `OnceLock`).
* tor-proto: replace `Channel`s "closed" state handlingSteven Engler2024-12-102-35/+47
| | | | | | | | | | | | | | | Previously `Channel` had two concepts of "closed". There was an atomic flag that was set to `true` at the end `Reactor::run`, and an experimental oneshot channel where the sender was dropped when the reactor was dropped. This commit consolidates these two using the `oneshot_broadcast` module. This means that the behaviour is consistent between both "closed" statuses (`is_closing()` and `wait_for_close()`). A channel is considered closed when its reactor is dropped. This also helps progress towards making the channel reactor cancellation safe (see arti#1756).
* tor-proto: move `ChannelDetails::reactor_closed_rx` to `Channel`Steven Engler2024-12-101-11/+17
| | | | This doesn't need to be shared with the reactor.

* Resolve clippy::manual_div_ceilNick Mathewson2024-12-031-1/+1
| | | | | | | This warning is new in 1.83. Surprisingly, it only triggered once. div_ceil was added in Rust 1.73, and our MSRV is 1.77, so div_ceil is fine to use.
* Resolve clippy::empty_line_after_doc_comments warnings.Nick Mathewson2024-12-031-1/+1
| | | | These are new in Rust 1.83.
* add_warnings, *: Allow clippy::needless_lifetimesNick Mathewson2024-12-031-0/+1
| | | | | | | | In 1.83, this warning triggers on many of our crates. We're thinking of fixing them all, but for now, we're going to disable the warning. This is part of #1765.
