* tor-persist: StateMgr: vagueify docs about NoLock errorIan Jackson2022-07-121-1/+1
| | | | `NoLock` is now a variant of `err::ErrorSource` but that is private.
* tor-persist: Big refactoring on Error type.Nick Mathewson2022-07-065-51/+211
| | | | | | | | | | | Every error now has an action (what we were trying to do), a resource (what we were trying to do it to), and a source (what problem we encountered). Initially I tried to add "action" and "resource" fields to error variants individually, but that led to a combinatorial explosion. Part of #323.

* Fix clippy::significant_drop_in_scrutinee warningsNick Mathewson2022-06-151-1/+2
| | | | | | | | | This is apparently a new warning from clippy nightly, documented in https://rust-lang.github.io/rust-clippy/master/index.html#significant_drop_in_scrutinee . I'm not in love with the temporary variables that this warning wants me to introduce, but it does seem like a decent way to avoid some kinds of deadlock.

* Regenerate version bump from previous commit.arti-v0.4.0Nick Mathewson2022-05-271-1/+1
| | | | | | | This commit was made by reverting the previous commit, then re-running the script I used to generate it. In theory there should be no semantic changes: only changes due to improved formatting from cargo edit.
* Semantic version changes for Arti 0.4.0 releaseNick Mathewson2022-05-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | I followed the following procedure to make these changes: * I used maint/changed_crates to find out which crates had changed since 0.3.0. * I used grep and maint/list_crates to sort those crates in topological (dependency) order. * I looked through semver_status to find which crates were listed as having semver-relevant changes (new APIs and breaking changes). * I scanned through the git logs of the crates with no semver-relevant changes listed to confirm that, indeed, they had no changes. For those crates, I incremented their patch-level version _without_ changing the version that other crates depend on. * I scanned through the git logs of the crates with no semver-relevant changes listed to confirm that, indeed, they had no obvious breaking changes. * I treated all crates that depend on `arti` and/or `arti-client` as having breaking changes. * I identified crates that depend on crates that have changed, even if they have not changed themselves, and identified them as having a non-breaking change. * For all of the crates, I used `cargo set-version -p $CRATE --bump $STATUS` (where `STATUS` is `patch` or `minor`) to update the versions, and the depended-upon versions.

* Bump all arti*, tor* crates to 0.2.0Nick Mathewson2022-04-011-2/+2
| | | | | | | | Not all of these strictly need to be bumped to 0.2.0; many could go to 0.1.1 instead. But since everything at the tor-rtcompat and higher layers has had breaking API changes, it seems not so useful to distinguish. (It seems unlikely that anybody at this stage is depending on e.g. tor-protover but not arti-client.)

| * 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.

* | arti-client: Unlock the state manager on failure to bootstrapeta2022-02-243-5/+33
|/ | | | | | | | | | | | `StateMgr` got a new `unlock()` method that does what it says on the tin. We now call it from `bootstrap()` using the new `util::StateMgrUnlockGuard`, which works in a manner similar to the `BoolResetter` from `tor_dirmgr`. (A decent small little task in future might be to unify these types in some sort of general arti utility crate?) closes arti#335

| * Make NoLock into BadApiUsage.Nick Mathewson2022-02-221-1/+1
| | | | | | | | | | | | To implement this, we had to refactor the tor_circmgr api for flushing state changes to disk, so that it checks if it has the lock, and only then tries to store.

* tor-persist: Distinguish load vs. store json errorsIan Jackson2022-02-043-10/+20
| | | | | | | | Serialisation errors ought not to occur, since they would represent an attempt to store malformed data, or something. (We always convert to a string, so the JSON error never contains IO errors or the like.) Deserialisation errors mean the persistent state is corrupt.

* clippy: Pass simply &output to fs::writeIan Jackson2022-02-021-1/+1
| | | | | | clippy::needless_borrow quibbles here, IMO correctly. Its suggestion didn't go far enough: output is a String and a &String can be passed to write as-is for identical effect.
* Bump all crate versions to 0.0.3.Nick Mathewson2022-01-111-1/+1

* Minimize the required version for each dependency.Nick Mathewson2022-01-071-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().
