* Preserve HTTP status text in dirclient errors.Nick Mathewson2023-11-291-1/+6
| | | | | | | | The HTTP status text is often useful for diagnosing errors. Tor directory and hsdir caches frequently put useful messages there, especially when rejecting an uploaded document. Inspired by #1142.

* Privacy: Do not list supported encodings in hsdesc reqs.Nick Mathewson2023-10-161-8/+34
| | | | | | | | | | | | | Since not everybody has xz and/or zstd, we don't want to admit whether we support them when we are uploading or downloading an onion service descriptor. Similarly, if we aren't advertising support for an encoding, we shouldn't accept it. Finally, while we're doing this, it made sense to have the ability to mark requests based on how anonymized they are, and reject (some) attempts to send those requests over a one-hop circuit. Closes #1062

* tor-dirclient: Rename download() to send_request().Gabriela Moldovan2023-08-161-6/+6
| | | | | | `download()` is actually a general-purpose function for sending HTTP requests on a stream. We will soon repurpose it for `POST`-ing descriptors, so let's rename it to `send_request`.

* tor-dirclient: De-genericise internal fn retire_circIan Jackson2023-01-301-2/+1
| | | | | | | Requring `Display` is wrong here, because if this is actually an Error, Display would be wrong because it doesn't display causes. As it happens, the `error` parameter is only ever `&str`.
* Allow clippy::unchecked_duration_subtraction in testsNick Mathewson2023-01-271-0/+1
| | | | | This panics on error, and we're fine with a panic on misbehavior in tests.
* Disable clippy::unlinlined-format-argsNick Mathewson2023-01-271-0/+1
| | | | | | | | This warning kind of snuck up on us! (See #748) For now, let's disable it. (I've cleaned it up in a couple of examples, since those are meant to be more idiomatic and user-facing.) Closes #748.

* tor-dirclient Response: Rename output methodsIan Jackson2022-10-201-4/+4
| | | | | These don't check errors and are therefore quite hazardous. I'm going to introduce a more cooked version in a moment.
* cargo fmt to remove blank linesIan Jackson2022-10-121-1/+0
| | | | | | | Apparently cargo fmt doesn't like these, which my perl rune didn't delete. This commit is precisely the result of `cargo fmt`.
* Replace all README copies in src/lib.rs with includesIan Jackson2022-10-121-25/+1
| | | | | | | | The feature we want is `#[doc = include_str!("README.md")]`, which is stable since 1.54 and our MSRV is now 1.56. This commit is precisely the result of the following Perl rune: perl -i~ -0777 -pe 's{(^//!(?!.*\@\@).*\n)+}{#![doc = include_str!("../README.md")]\n}m' crates/*/src/lib.rs

* | dirclient: Collect and expose peer information from errors.Nick Mathewson2022-03-211-42/+89
| | | | | | | | | | | | | | | | | | | | This commit refactors the dirclient error type into two cases: errors when constructing a circuit, and errors that occur once we already have a one-hop circuit. The latter can usually be attributed to the specific cache we're talking to. This commit also adds a function to expose the information about which directory gave us the info.

* | Disable clippy::clone_on_ref_ptrIan Jackson2022-02-241-1/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This lint is IMO inherently ill-conceived. 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.
* dirclient: Remove HttpStatus error variantNick Mathewson2022-02-171-2/+7
| | | | | | | Getting a non-200 status is no longer a failure condition; it's just a different kind of answer. Closes #349.
* Change deny(clippy::all) to warn(clippy::all).Nick Mathewson2022-02-141-1/+1
| | | | Closes #338.

| | | | | | | | | | These bring the case a tiny improvement in test coverage, and also manage to turn up a few bugs.
| * dirclient: don't return too-long responses on decompression failureNick Mathewson2022-02-011-0/+2
| | | | | | | | | | | | | | | | | | There are a couple of places where we forgot to truncate our return-buffer to its actual size, and instead returned a big bunch of zeros. Found while writing the tests in the next commit. Someday, we'll have ReadBuf and won't have to worry about these things.
* | Untangle two needless Ok(r?) into just rIan Jackson2022-02-021-1/+1
|/ | | | | | Prompted by clippy::needless_question_mark. Sometimes Ok(r?) is needed to do automatic error conversion. I assume the lint checks for that. Anyway, in these cases it's not needed.

| | | | | | | | We want to only use TODO in the codebase for non-blockers, and open tickets for anything that is a bigger blocker than a TODO. These XXXXs seem like definite non-blockers to me. Part of arti#231.
