* tor-rtmock: Avoid confusing "concurrently" wordIan Jackson2025-02-251-2/+2
|
* tor-rtmock: Explain Subthreads and compare them with bare threadsIan Jackson2025-02-251-0/+31
|
* tor-rtmock: Capitalise Subthread and link to the definitionIan Jackson2025-02-251-25/+29
| | | | | This makes it clearer that this is a specific term, which a definition.
* tor-rtmock: Fix a typoIan Jackson2025-02-251-1/+1
| | | | | As per https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/2793#note_3161972
* tor-rtmock: Move imprecations to more prominent locationIan Jackson2025-02-251-11/+9
| | | | | The rustdocs for a fn in a trait impl are rendered, but are very unobvious. Put the information in the top-level documentation.
* tor-rtmock: subthread facilityIan Jackson2025-02-131-7/+381
| | | | We'll expose this with some new traits in tor_rtmock.
* tor-rtmock: subthread facility (pre-fmt)Ian Jackson2025-02-131-2/+10
|
* tor-rtmock: Replace open-coded Debug impl with DeriveIan Jackson2025-02-131-34/+27
| | | | | | | No change to output, but much less open-coding. Move the doc comment that was on the Debugg impl, to the `DebugTasks` helper struct.
* tor-rtmock tests: Improve various_mock_executorsIan Jackson2025-02-131-0/+1
| | | | Show where each test sub-case is started, in stderr output.
* tor-rtmock tests: Break out various_mock_executorsIan Jackson2025-02-131-5/+10
| | | | We're going to add another call site.
* tor-rtmock: Break out Task::set_awakeIan Jackson2025-02-131-7/+19
| | | | We're going to add another call site.
* tor-rtmock: task: Rename MockExecutor Arc<Shared> field to sharedIan Jackson2025-02-131-17/+17
|
* tor-rtmock: task: Replace ArcMutexData with Arc<Shared>Ian Jackson2025-02-131-12/+20
| | | | | | | | | | | | | We're going to want to add a field inside the Arc but not inside the Mutex, so make the Arc contents into a named-fields struct. We don't need ArcMutexData any more. Arc<Shared> will do fine. Previously, we needed to implement .lock() on ArcMutexData but because Arc<Shared> derefs to Shared, we can implement it on Shared just as well. The field in MockExecutor ought to be renamed, but that's textually intrusive so will come in the next commit.
* tor-rtmock: Correct a commentIan Jackson2025-02-131-1/+1
| | | | | In an earlier version of this code there was a Polling state, but there isn't now.

* tor-rtmock: drop_reentrancy test: Run under miri tooIan Jackson2025-01-151-8/+14
|
* tor-rtmock: Explicitly manage the lifetime of the futureIan Jackson2025-01-151-0/+7
| | | | | | | | | | | Previously, if r is Pending, `fut` is moved out of (stored in `task.fut`), whereas if r is Ready, it is retained and then dropped at the end of the loop iteration. This is quite subtle, and involves `fut` being in a "maybe moved out of" state (which cannot be represented in Rust's surface type system) after the block with the `data` lock. Let's write code that more clearly ensures that the compiler DTRT.
* tor-rtmock: Add a test case for Future drop entrancyIan Jackson2025-01-151-0/+34
| | | | | This passes right now, but only because the lifetime of the `fut` variable in `execute_until_first_stall` happens to be right.
* tor-rtmock: Avoid misleading task dumps by careful drop sequencingIan Jackson2025-01-151-9/+34
|
* tor-rtmock: Add some more tracing / debug outputIan Jackson2025-01-151-1/+9
|
* tor-rtmock: Explain a difficulty with test trace outputIan Jackson2025-01-151-0/+5
|
* tor-rtcompat: Use GAT instead of RPIT in SpawnBlocking trait.Wesley Aptekar-Cassels2025-01-071-3/+6
| | | | Due to the limitations on RPIT, it's better to use a GAT for now.
* tor-rtmock: Add task names for spawn_obj and spawn_blocking.Wesley Aptekar-Cassels2025-01-071-2/+2
|
* tor-rtcompat: Add spawn_blocking to Runtime trait.Wesley Aptekar-Cassels2025-01-071-1/+37
| | | | | This adds a new SpawnBlocking trait, which exposes the spawn_blocking function that tokio, async-std, and other runtimes have.
* fix: fix typosDimitris Apostolou2025-01-061-2/+2

* Convert a few crates to slotmap-carefulNeel Chauhan2024-10-171-3/+3
|
* tor-rtmock: Add some commentary about SleepLocationIan Jackson2024-10-081-0/+6
| | | | | As per https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/2502#note_3090557
* tor-rtmock: Fix a memory leakIan Jackson2024-10-081-6/+20
| | | | | | Change the waker to have a weak reference to the executor. Detected by miri.
* tor-rtmock: Provide a fake SleepProvider for miriIan Jackson2024-10-081-0/+16
|
* extract tor_async_utils::oneshot into ::oneshot-fused-workaroundJim Newsome2024-08-281-1/+2
| | | | | | | | | | | | | | Having this in the `tor-async-utils` crate prevents us from doing both of the following without introducing a circular dependency: * using it in `tor-rtmock` (which we currently do, particularly in tests). * using `tor-rtmock` to test things in `tor-async-utils`. We don't do this yet, but it is generally sensible to do so. In particular we want to move the `stream_peak` module there, which is currently tested with `tor-rtmock`. Moving this into its own crate avoids this circular dependency.
* Match previous backtrace formattingRobin Leander Schröder2024-08-081-1/+1
| | | | | std::backtrace::Backtrace's Display looks the same as backtrace_rs::Backtrace's Debug
* Use std::backtrace instead of backtrace crateRobin Leander Schröder2024-08-011-33/+8
| | | | | Removes resolve_backtraces from rtmock since it is no longer needed as stdlib's backtraces automatically lazily resolve without needing a &mut.
* Suppress a spurious dead code lintIan Jackson2024-04-251-0/+1

* Run maint/add_warning.Nick Mathewson2024-03-131-0/+1

* tor-rtmock: get rid of unwrap()Saksham Mittal2023-11-211-1/+1
|
* tor-rtmock: handle Receiver result inside spawn_join()Saksham Mittal2023-11-211-2/+2
|
* tor-rtmock: use expect() insteadSaksham Mittal2023-11-211-1/+2
|
* tor-rtmock: change return types to be less concreteSaksham Mittal2023-11-211-1/+1
|
* tor-rtmock: change return type of spawn_join()Saksham Mittal2023-11-211-3/+3
| | | | | This makes it synchronous. The trait bounds on the return type have also been relaxed to not require Clone
* tor-rtmock: introduce spawn_join() for MockRuntime & MockExecutorSaksham Mittal2023-11-211-0/+17
| | | | | | | This helps abstract away the need to create a oneshot channel in order to get the return value out of an async function when using MockRuntime. ref: https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/1727#note_2965352
* tor-rtmock: MockExecutor: Provide n_tasks accessorIan Jackson2023-10-161-0/+15
|
* tor-rtmock: task backtraces: Expand on spurious backtracesIan Jackson2023-09-131-2/+7
| | | | There's another reason you can see multiple backtraces.
* tor-rtmock: task backtraces: Fix output re backtrace multiplicityIan Jackson2023-09-131-2/+10
| | | | | | | There may be several backtraces for an asleep task. If so, print the prefix for each one. There may be no backtraces for an asleep task. If so, print a message.
* tor-rtmock: task: Add missing doc commentIan Jackson2023-09-131-1/+3
|
* tor-rtmock: task: Add warning about backtrace salienceIan Jackson2023-09-131-2/+34
| | | | With explanation of how it works.
* tor-rtmock: task: Add backtrace dumping callsIan Jackson2023-09-131-4/+4
| | | | | | | Do a full dump, not just a normal Debug dump, when we're panicking in progress_until_stalled. Add a debug dump call to one of the tests, so we can see it working.
* tor-rtmock: task: Add API for printing dumps including backtracesIan Jackson2023-09-131-3/+77
|
* tor-rtmock: task: Capture sleep backtraces, with code to dumpIan Jackson2023-09-131-4/+75
| | | | Currently nothing actually calls the dumping code.
* tor-rtmock: task: Prepare for ActualWaker::clone taking the data lockIan Jackson2023-09-131-4/+28
|
* tor-rtmock: task: Switch to unsafe RawWaker approachIan Jackson2023-09-131-5/+83
