* proto: make padding::Parameters construction fallible.Nick Mathewson2025-03-184-23/+106
| | | | | | | The constructor for rand::distr::Uniform is now fallible, so it makes sense to bubble up its restrictions. This is a breaking change.
* squash! Upgrade rand dependency to 0.9.Nick Mathewson2025-03-181-1/+1
| | | | - The Rng::gen() functions have been renamed to Rng::random().
* squash! Upgrade rand dependency to 0.9.Nick Mathewson2025-03-181-3/+2
| | | | | | - `rand::thread_rng()` has been deprecated and renamed to `rand::rng()` (I missed these cases because they were from prelude::*)
* squash! Upgrade rand dependency to 0.9.Nick Mathewson2025-03-181-1/+2
| | | | - `Uniform::new_inclusive` is now fallible.
* squash! Upgrade rand dependency to 0.9.Nick Mathewson2025-03-181-4/+0
| | | | - `try_fill_bytes()` is no longer a member of RngCore.

* Upgrade rand dependency to 0.9.Nick Mathewson2025-03-181-2/+2
| | | | | | (Per discussion at #1774, we think the changes are acceptable.) This commit won't compile on its own; subsequent commits will fix it.

* tor-proto: begin using `TargetHop` and `HopLocation`Steven Engler2025-03-116-40/+126
| | | | | | | | This doesn't yet change the public API, it just begins the work of plumbing these around throughout `ClientCirc`, `Reactor`, etc. This can't be broken up into smaller commits without causing build failures.

| | | | | | | MockSleepProvider and MockSleepRuntime have been declared deprecated by the docs for some time. We're about to mark them `#[deprecated]`. This commit has been split out for clarity of review.

* tor-proto: Move Circuit to its own module.Gabriela Moldovan2025-03-069-1325/+1393
| | | | | | | | | | | This is mostly code motion + some visibility adjustments. Moving all of these outside of `reactor` makes it easier to see which parts are internal vs which are accessed by the reactor. It also helps us enforce/audit invariants such as 'there should be no contention on the `CircHop::map` mutex' (the stream map is now private to `reactor::circuit`, and therefore nothing inside `reactor` will be directly accessing it).
* tor-proto: Avoid accessing CircHop internals from the reactor.Gabriela Moldovan2025-03-063-2/+16
| | | | This will enable us to move `CircHop` out of `reactor.rs`.
* tor-proto: Avoid accessing Circuit internals from the reactor.Gabriela Moldovan2025-03-062-3/+16
| | | | This will enable us to factor `Circuit` out of `reactor.rs`.
* tor-rtmock: task: Remove Default impl for ThreadDescriptorIan Jackson2025-03-041-1/+1
| | | | | | | | | This is going to become a hazard. Let's be explicit. This means using educe to derive the Default for Data. We also need to update our educe dependency to 0.4.22, since that's when Default(expression= "...") started working correctly.

| | | | | | | | | | | | In aa08ede11fd483cd6dcb4522c431f9e07001717e, the reactor loop was rewritten to unconditionally read from the `CtrlMsg` channel, so we need to adjust the docs.

| | | | | | | | | | | | | | | Some of these were supposed to be `bad_api_usage`, because they result from API misuse rather than an internal error (bug).

| | | | | | | | | | | | | | | This will enable us to reuse these checks for implementing other methods that are only supported if the conflux set has a single leg.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit updates the `Reactor::run_once()` loop to attempt to read from (and write to) all of its circuit legs as opposed to just the primary one. Note that this slightly changes the behavior of the reactor. Previously, we'd only read from the control channel if the `chan_sender` was ready, whereas now the control channel is unconditionally read from, in the *outer* select. The overall effect is that the control channel can cause unbounded buffering in the `chan_sender` of each circuit (which can happen if the `chan_sender` is not ready to send). This was actually how the reactor worked before the refactoring from !2747, which is reflected in the `chan_sender` docs: ```rust /// Sender object used to actually send cells. /// /// NOTE: Control messages could potentially add unboundedly to this, although that's /// not likely to happen (and isn't triggereable from the network, either). chan_sender: SometimesUnboundedSink<AnyChanCell, ChannelSender>, ``` I don't believe this to be a problem, for the reason mentioned in the `chan_sender` docs, and because the main reason we check for `chan_sender` readiness is to apply backpressure on senders, which is not something we need to worry about when it comes to the control channel. Besides, the control channel is unbounded, so not reading from it won't stop the senders from sending more commands anyway. Closes #1863
| * tor-proto: Add a SelectResult::RemoveLeg command.Gabriela Moldovan2025-02-271-0/+6
| | | | | | | | | | This tells the reactor to remove a given circuit from the conflux set, and will be used to remove the circuits that have been shut down.
