* | | RetryDelay: add accessors for stateNick Mathewson2022-03-161-5/+22
|/ / | | | | | | | | We'll need these for our unit tests in tor-dirmgr once we move RetryDelay into tor-basic-utils.

| * | dirmgr: Call shrink_to_fit on missing-microdesc hashtableNick Mathewson2022-03-101-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This hashtable starts out pretty large, but it can spend most of our runtime (when we aren't downloading) being small. To avoid doing too much work, I've made it so we only call shrink_to_fit twice per consensus: once when we're no longer pending, and once when we're complete. Closes #388.
* | | humantime: Update to humantime-serde 1.1.1Ian Jackson2022-03-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This has the humantime_serde::option module, which we have upstreamed and are about to switch to. The remaining dependency with version = "1" is going to be removed in a moment.

* | | Derive Deserialize for derive-builder-generated config buildersIan Jackson2022-03-072-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I used git-grep -P '\#\[serde\((?!default|deny_unknown)' to find places where I needed to add additional attributes on the builder method fields. This is currently a bit duplicative, but when #371 is completely done, the validated (non-builder) configs won't need to be Deserialize any more. This is part of #371 and #372.
* | | Use git source for derive_builder for now, for attrs featureIan Jackson2022-03-071-1/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | We are going to want to specify custom attributes on fields of the builder struct. This feature was missing from derive_builder. This commitid is the current head of my MR branch https://github.com/colin-kiegel/rust-derive-builder/pull/237 https://github.com/ijackson/rust-derive-builder/tree/builder-field-attrs Using the commitid prevents surprises if that branch is updated. We will require this newer version of derive_builder. The version will need to be bumped again later, assuming the upstream MR is merged and upstream do a release containing the needed changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the EventStream associated type and the Runtime parameter. The Runtime parameter wasn't actually used for anything, and the EventStream was easy enough to replace with a BoxStream in this case. Also replaced DirBootstrapEvents with a BoxStream to avoid tying anything to our backend.

I have looked for the reasons why this might be thought to be a good idea and there were basically two (and they are sort of contradictory): I. "Calling ‘.clone()` on an Rc, Arc, or Weak can obscure the fact that only the pointer is being cloned, not the underlying data." This is the wording from https://rust-lang.github.io/rust-clippy/v0.0.212/#clone_on_ref_ptr It is a bit terse; we are left to infer why it is a bad idea to obscure this fact. It seems to me that if it is bad to obscure some fact, that must be because the fact is a hazard. But why would it be a hazard to not copy the underlying data ? In other languages, faliing to copy the underlying data is a serious correctness hazard. There is a whose class of bugs where things were not copied, and then mutated and/or reused in multiple places in ways that were not what the programmer intended. In my experience, this is a very common bug when writing Python and Javascript. I'm told it's common in golang too. But in Rust this bug is much much harder to write. The data inside an Arc is immutable. To have this bug you'd have use interior mutability - ie mess around with Mutex or RefCell. That provides a good barrier to these kind of accidents. II. "The reason for writing Rc::clone and Arc::clone [is] to make it clear that only the pointer is being cloned, as opposed to the underlying data. The former is always fast, while the latter can be very expensive depending on what is being cloned." This is the reasoning found here https://github.com/rust-lang/rust-clippy/issues/2048 This is saying that *not* using Arc::clone is hazardous. Specifically, that a deep clone is a performance hazard. But for this argument, the lint is precisely backwards. It's linting the "good" case and asking for it to be written in a more explicit way; while the supposedly bad case can be written conveniently. Also, many objects (in our codebase, and in all the libraries we use) that are Clone are in fact simply handles. They contain Arc(s) (or similar) and are cheap to clone. Indeed, that is the usual case. It does not make sense to distinguish in the syntax we use to clone such a handle, whether the handle is a transparent Arc, or an opaque struct containing one or more other handles. Forcing Arc::clone to be written as such makes for code churn when a type is changed from Arc<Something> to Something: Clone, or vice versa.

| | | | | | | | | | | | | | | | It had too many possible Kinds depending on what kind of string had failed to parse. I decided to use #[source] here instead of #[from], so that we would have to explicitly convert these errors where they show up.

* | arti-client: add ability to automatically bootstrapeta2022-02-161-2/+2
|/ | | | | | | | | | | | | The new `BootstrapBehavior` enum controls whether an unbootstrapped `TorClient` will bootstrap itself automatically (`Ondemand`) when an attempt is made to use it, or whether the user must perform bootstrapping themselves (`Manual`). The `lazy-init` example shows how you could write a simple `get_tor_client()` function that used a global `OnceCell` to share a Tor client across an entire application with this API. closes arti#278

* Allow creating unbootstrapped `TorClient`s (and `DirMgr`s)eta2022-02-112-24/+159
| | | | | | | | | | | | | | | This commit changes how the `TorClient` type works, enabling it to be constructed synchronously without initiating the bootstrapping process. Daemon tasks are still started on construction (although some of them won't do anything if the client isn't bootstrapped). The old bootstrap() methods are now reimplemented in terms of the new create_unbootstrapped() and bootstrap_existing() methods. This required refactoring how the `DirMgr` works to enable the same sort of thing there. closes #293
