| * Integrate status information at arti-clientNick Mathewson2022-01-182-40/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit combines status update information from tor-dirmgr and tor-chanmgr in the arti-client crate, so that the user can get to it; it represents a high-level view of the client's ability to reach the network and route traffic. I have omitted the tor-circmgr support for now; it's mostly not needed. At present it's not so useful, since there's no way for a client to get a TorClient that _isn't_ completely bootstrapped, and therefore there's no way to actually watch these events until they're no longer interesting. That should change with arti#293. This is part of #96.
* | Put our cache files in the right place.Nick Mathewson2022-01-181-1/+1

* Implement the basics of a bootstrap-status API.Nick Mathewson2022-01-134-1/+222
| | | | | | | | | | | | The purpose of a this API is to tell the user how far along Arti is in getting bootstrapped, and if it's stuck, what it's stuck on. This API doesn't yet expose any useful information: by the time it's observable to a client, it's always "100% bootstrapped." But I'm putting it in a MR now so that we can review the basic idea, and to avoid conflicts with later work on tickets like #293 and #278. This is part of #96.

| * Improve the layout of crate exports; add runtime convenience functionseta2022-01-113-6/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit addresses multiple problems highlighted by arti#182: - `arti-client` had some types in its public API that weren't accessible without importing another crate (`CfgPath`, `DataReader`, `DataWriter`). This has been fixed. - In addition, the doc comments for `DataReader` and `DataWriter` were cleaned up to be of better quality, now that they're public. - It was impossible to use `arti-client` without also importing `tor-rtcompat`. This is now fixed by the addition of two convenience methods: `TorClient::bootstrap_with_tokio` and `TorClient::bootstrap_with_async_std`. - Potentially controversially: `tor-rtcompat` now returns *concrete* types from methods like `current_runtime`, instead of `impl Runtime`. - This was needed in order to actually be able to name the `TorClient` type that results from using these methods. - This does mean we lose API flexibility, but on balance I think this is a good thing, because the API we *do* have is actually usable...

| * Expose and rename stream timeout config.Nick Mathewson2022-01-102-18/+26
| | | | | | | | | | | | | | | | | | | | | | Previously we kept this in an ambiguously named type, `ClientTimeoutConfig`. But everything we do right now is client related! So `StreamTimeoutConfig` is a better name. Also, we'd previously neglected to expose the builder for this type from `TorClientConfigBuilder`. Now we do. Closes #281.

| * Minimize the required version for each dependency.Nick Mathewson2022-01-071-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I found these versions empirically, by using the following process: First, I used `cargo tree --depth 1 --kind all` to get a list of every immediate dependency we had. Then, I used `cargo upgrade --workspace package@version` to change each dependency to the earliest version with which (in theory) the current version is semver-compatible. IOW, if the current version was 3.2.3, I picked "3". If the current version was 0.12.8, I picked "0.12". Then, I used `cargo +nightly upgrade -Z minimal-versions` to downgrade Cargo.lock to the minimal listed version for each dependency. (I had to override a few packages; see .gitlab-ci.yml for details). Finally, I repeatedly increased the version of each of our dependencies until our code compiled and the tests passed. Here's what I found that we need: anyhow >= 1.0.5: Earlier versions break our hyper example. async-broadcast >= 0.3.2: Earlier versions fail our tests. async-compression 0.3.5: Earlier versions handled futures and tokio differently. async-trait >= 0.1.2: Earlier versions are too buggy to compile our code. clap 2.33.0: For Arg::default_value_os(). coarsetime >= 0.1.20: exposed as_ticks() function. curve25519-dalek >= 3.2: For is_identity(). generic-array 0.14.3: Earlier versions don't implement From<&[T; 32]> httparse >= 1.2: Earlier versions didn't implement Error. itertools at 0.10.1: For at_most_once. rusqlite >= 0.26.3: for backward compatibility with older rustc. serde 1.0.103: Older versions break our code. serde_json >= 1.0.50: Since we need its Value type to implement Eq. shellexpand >= 2.1: To avoid a broken dirs crate version. tokio >= 1.4: For Handle::block_on(). tracing >= 0.1.18: Previously, tracing_core and tracing had separate LevelFilter types. typenum >= 1.12: Compatibility with rust-crypto crates x25519-dalek >= 1.2.0: For was_contributory(). Closes #275.

| * Oops: MutCfg shouldn't implement Clone.Nick Mathewson2021-12-071-4/+7
| | | | | | | | | | | | | | | | We don't want MutCfg to be automatially coneable, or we'll wind up with surprises like the one that this patch fixes in TorClient. (The "surprise" is that reconfigure() would only apply its client-specific options to one client instance.)
| * Sequence reconfiguration requests.Nick Mathewson2021-12-071-8/+25
| | | | | | | | | | | | If we allow overlapping reconfiguration requests, we introduce all kinds of "fun" bugs. For example, we could wind up with a configuration made up of parts of one reconfiguration attempt, and parts of another.

| * Allow on-the-fly changing of path_rulesNick Mathewson2021-12-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | And now the complexity begins: when the user changes the path_rules, they not only want new circuits to obey those rules: they want _all new requests_ to be put onto circuits that obey those rules. That means that when the path rules become more restrictive, we need to retire all the circuits, and make sure that currently pending circuits aren't used for any requests. If it's any comfort, doing this was even more complicated in C tor. ;)
| * Sketch API for reconfiguration.Nick Mathewson2021-12-072-4/+58
| | | | | | | | | | | | | | This patch doesn't actually make anything reconfigurable, but it does create an API that will tell you "you can't change the value of that!" If the API looks reasonable, I can start making it possible to change the values of individual items.
