Summary

  • expand push queue builder docs with a complete example covering capacities, rate limits, and dead-letter queue behaviour
  • document rate and DLQ setters, noting that None disables throttling and frames are dropped when the DLQ is absent or full
  • clarify lint expectations in connection actor fixtures and validate builder rates with an explicit branch
  • refine deprecated constructors' error messages and mark PushError as non-exhaustive
  • deduplicate deprecated constructors via a shared build_via_builder helper

Testing

Summary by Sourcery

Introduce a fluent builder API for PushQueues with configurable capacities, rate limits, and dead-letter queue support, replacing the deprecated bounded_* constructors.

New Features:

  • Add PushQueuesBuilder for configuring high_capacity, low_capacity, rate, and dlq before building queues and handles
  • Expose PushConfigError for builder validation errors and MAX_PUSH_RATE constant
  • Mark PushError variants non-exhaustive

Enhancements:

  • Deprecate old PushQueues::bounded* constructors and consolidate their logic via a shared helper
  • Enforce validation for zero or out-of-range rates and zero capacities in debug and release builds
  • Rename PushError::Full to PushError::QueueFull and refine error messages

Documentation:

  • Update all user-facing documentation and examples to demonstrate the builder pattern
  • Refine rate-limit and dead-letter queue behavior in push queue docs

Tests:

  • Add fixtures and tests to verify builder rejects invalid rates and capacities
  • Update existing tests to use the new builder API and lint expectations

Chores:

  • Replace unwrap() on binding an existing listener with expect() to provide clearer messages in server tests

Poem

Two queues now dance in fluent chain,
High and low in tidy lane.
A builder whispers: rate? DLQ?
Then hands you handle, shining new.
Frames glide past the leaky gate—
Drop, warn, or wait—decide their fate.
Green ticks hum: ship the update! 🚀

🧩 Analysis chain

@leynos I'll analyze the complex conditional and provide a fix with an AI agent prompt.

Based on the complex conditional flagged by CodeScene, here's my suggested fix:

Fix for Complex Conditional

Extract the rate validation logic into a predicate function to reduce complexity and improve readability:

/// Validates if the provided rate is invalid (None, 0, or exceeds MAX_PUSH_RATE).
fn is_invalid_rate(rate: Option<usize>) -> bool {
    match rate {
        Some(r) => r == 0 || r > MAX_PUSH_RATE,
        None => false,
    }
}

pub(super) fn build_with_rate_dlq(
    high_capacity: usize,
    low_capacity: usize,
    rate: Option<usize>,
    dlq: Option<mpsc::Sender<F>>,
) -> Result<(Self, PushHandle<F>), PushConfigError> {
    if is_invalid_rate(rate) {
        // ... rest of the validation logic
    }
    // ... rest of the function
}

AI Agent Prompt

Refactor the complex conditional in the `build_with_rate_dlq` function in `src/push/queues/mod.rs`:

1. Create a new private function `is_invalid_rate(rate: Option<usize>) -> bool` that:
   - Returns `false` if rate is `None`
   - Returns `true` if rate is `Some(r)` where `r == 0 || r > MAX_PUSH_RATE`
   - Add a doc comment explaining it validates if the rate is invalid

2. Replace the existing complex conditional `if let Some(r) = rate && (r == 0 || r > MAX_PUSH_RATE)` with `if is_invalid_rate(rate)`

3. Place the new function before the `build_with_rate_dlq` function in the same impl block

4. Ensure the function follows the coding guidelines:
   - Use en-GB spelling in documentation
   - Place any attributes after doc comments
   - Keep the function concise and focused on single responsibility

The goal is to reduce the cyclomatic complexity by extracting the validation logic into a dedicated predicate function.

This refactoring separates the validation concern into its own function, making the main logic clearer and reducing the complexity of the conditional statement.


🏁 Script executed:

#!/bin/bash
# Get more context around the complex conditional to understand the full function
rg -n -A 10 -B 5 "build_with_rate_dlq" src/push/queues/mod.rs

Length of output: 1416


Perfect! Now I can see the complete context. Here's my refined fix and AI agent prompt:

Fix for Complex Conditional

Extract the rate validation logic into a predicate function within the same impl block:

impl<F: FrameLike> PushQueues<F> {
    /// Start building a new set of push queues.
    #[must_use]
    pub fn builder() -> PushQueuesBuilder<F> { PushQueuesBuilder::default() }

    /// Validates if the provided rate is invalid (zero or exceeds maximum).
    fn is_invalid_rate(rate: Option<usize>) -> bool {
        matches!(rate, Some(r) if r == 0 || r > MAX_PUSH_RATE)
    }

    pub(super) fn build_with_rate_dlq(
        high_capacity: usize,
        low_capacity: usize,
        rate: Option<usize>,
        dlq: Option<mpsc::Sender<F>>,
    ) -> Result<(Self, PushHandle<F>), PushConfigError> {
        if Self::is_invalid_rate(rate) {
            // Reject unsupported rates early to avoid building queues that cannot
            // be used. The bounds prevent runaway resource consumption.
            // ... rest of validation logic
        }
        // ... rest of function
    }
}

AI Agent Prompt

Refactor the complex conditional in the `build_with_rate_dlq` function in `src/push/queues/mod.rs` at line 75-77:

1. Add a new private helper function within the `impl<F: FrameLike> PushQueues<F>` block, positioned after the `builder()` function and before `build_with_rate_dlq()`:

```rust
/// Validates if the provided rate is invalid (zero or exceeds maximum).
fn is_invalid_rate(rate: Option<usize>) -> bool {
    matches!(rate, Some(r) if r == 0 || r > MAX_PUSH_RATE)
}
```

2. Replace the existing complex conditional on lines 75-77:
   - FROM: `if let Some(r) = rate && (r == 0 || r > MAX_PUSH_RATE)`
   - TO: `if Self::is_invalid_rate(rate)`

3. Keep the existing comment block that follows the conditional unchanged, as it explains the validation purpose.

4. Ensure the new function follows Rust coding guidelines:
   - Use `matches!` macro for concise pattern matching
   - Include a clear doc comment with en-GB spelling
   - Make it a private function (no `pub` keyword)

This refactoring reduces the cyclomatic complexity by extracting the validation logic into a dedicated predicate function, making the main conditional simpler and more readable.

This solution uses the matches! macro for cleaner pattern matching and keeps the validation logic encapsulated while simplifying the main conditional structure.

137-165: Fix: timeout under paused time never fires (test will hang)

With time::pause(), timeout(...) won’t elapse unless you advance time. Build the timeout future first, advance virtual time, then await it.

Apply:

-    let attempt = match priority {
-        PushPriority::High => {
-            time::timeout(Duration::from_millis(10), handle.push_high_priority(2u8)).await
-        }
-        PushPriority::Low => {
-            time::timeout(Duration::from_millis(10), handle.push_low_priority(2u8)).await
-        }
-    };
-
-    assert!(attempt.is_err(), "second push should block");
+    let attempt = match priority {
+        PushPriority::High => time::timeout(Duration::from_millis(10), handle.push_high_priority(2u8)),
+        PushPriority::Low => time::timeout(Duration::from_millis(10), handle.push_low_priority(2u8)),
+    };
+    time::advance(Duration::from_millis(10)).await;
+    assert!(attempt.await.is_err(), "second push should block");

186-202: Fix: same paused-time timeout issue

Advance time before awaiting the timeout.

Apply:

-    let attempt = time::timeout(Duration::from_millis(10), handle.push_low_priority(2u8)).await;
-    assert!(attempt.is_err(), "second push should block across queues");
+    let attempt = time::timeout(Duration::from_millis(10), handle.push_low_priority(2u8));
+    time::advance(Duration::from_millis(10)).await;
+    assert!(attempt.await.is_err(), "second push should block across queues");

239-244: Fix: paused-time timeout again

Advance virtual time before awaiting the timeout.

Apply:

-    let res = time::timeout(Duration::from_millis(10), handle.push_high_priority(99)).await;
-    assert!(
-        res.is_err(),
+    let res = time::timeout(Duration::from_millis(10), handle.push_high_priority(99));
+    time::advance(Duration::from_millis(10)).await;
+    assert!(
+        res.await.is_err(),
         "Push exceeding burst capacity should be rate limited"
     );

256-270: LGTM: builder example accurately shows rate(None) disabling throttling.

The example uses the builder API correctly, returns a Result, and explains the unlimited path. No action required.

src/session.rs (1)

86-89: Remove unnecessary capacity specification note: builder defaults to high_capacity = 1 and low_capacity = 1, so PushQueues::<u8>::builder().build() compiles as-is.

src/push/queues/errors.rs (1)

1-30: Error types look solid and aligned with the builder API.

#[non_exhaustive] usage, messages, and separation between push-time and config-time errors are appropriate.

tests/connection_actor.rs (2)

398-410: Backpressure check reads well; ensure deterministic timing on slow CI

The 50ms timeout is small; bump to 100–200ms to reduce flakes on slow runners.

Do you want a commit to raise the timeout and rerun CI?


489-494: LGTM: Builder usage in loop

The switch to the builder is correct and keeps each actor isolated.

src/push/mod.rs (1)

21-31: LGTM: Re-exports and crate-only internals

Public surface and crate-visible internals are appropriately split.

tests/push.rs (12)

5-15: LGTM: Imports reflect the new public API

New names and constants are correctly referenced.


18-26: LGTM: Builder-based fixtures

Fixtures align with the builder API and explicit generics.

Also applies to: 28-35


37-44: LGTM: Invalid rate coverage

The test correctly exercises 0 and MAX+1.


46-79: LGTM: Zero-capacity paths (debug/release)

Assertions match debug_assert behaviour and release-time validation.


81-97: LGTM: Priority routing sanity-check

Assertions match expected ordering.


98-116: LGTM: Policy returns QueueFull

Variant and behaviour match the new API.


120-127: LGTM: Closed-state errors

Both priorities surface Closed as expected.


171-179: LGTM: Rate reset after window

Virtual time usage is correct.


208-214: LGTM: Unlimited rate path

rate(None) behaves as expected.


228-234: LGTM: Burst config (cap=4, rate=3)

Config matches the test’s intent.


248-252: LGTM: Dequeue order after refill

Expectations align with rate-limited burst semantics.


137-165: The script will list any time::pause() and time::timeout usages in tests/push.rs so you can confirm that every timeout under a paused clock is intended and paired with a subsequent time::advance. After seeing the output, verify there are no unintentional blocking tests.

tests/push_policies.rs (1)

42-47: LGTM: Builder replaces deprecated constructors (with DLQ/rate where needed)

Conversions look correct and explicit generics aid clarity.

Also applies to: 85-91, 149-155

src/push/queues/builder.rs (2)

1-46: LGTM: Clear module docs and examples

Docs are thorough and use rust,no_run appropriately.


54-63: LGTM: Defaults, validation, and Result-returning build

  • Defaults mirror prior constructors.
  • Debug assertions complement release-time validation in build().
  • API shape matches tests and exports.

Also applies to: 65-81, 82-99, 100-109

src/push/queues/handle.rs (1)

34-49: Core push path looks correct and cancellation-safe

Await the limiter, pick the correct channel, map send failures to PushError::Closed, and emit debug logs. No correctness issues here.

src/push/queues/mod.rs (1)

217-234: LGTM on biased recv loop

Bias towards high priority is explicit and documented; closed-channel handling is correct.

In tests/world.rs around lines 145 to 149, the PushQueues builder does not
explicitly set rate, risking future flakiness; call .rate(None) on the builder
chain before .build() to lock in unthrottled (unlimited) behavior, then keep the
existing .expect(...) handling.

🧹 Nitpick (assertive)

Repeat: disable throttling explicitly here as well.

Mirror the above change for consistency.

In tests/world.rs around lines 187–191, the PushQueues builder call needs to
explicitly disable throttling to match the earlier change; update the builder
chain to call the disable_throttling() method (before build()) on
PushQueues::<u8>::builder() so throttling is turned off here as well, and add
any necessary use/import if disable_throttling is not in scope.

@coderabbitai Have the following now been resolved?

  • Tests still repeat PushQueues builder invocations in several places; consider extracting a shared helper or fixture to reduce duplication.
  • The builder methods use debug_assert to enforce non-zero capacity only in debug builds; consider moving capacity validation into build() to guarantee consistent checks in release.
  • It may help to add a high-level example of the new PushQueues::builder API to the crate root README or lib docs so users can quickly find and use the builder pattern.

@coderabbitai Has the following now been resolved?

  1. Test duplication - ⚠️ PARTIALLY RESOLVED: Some fixtures exist (queues(), small_queues()) that reduce duplication, but many test files still repeat the full builder pattern. Progress has been made but further consolidation would be beneficial.

🧩 Analysis chain

@leynos Looking at the current state of the test duplication issue:

Test Duplication Status: ⚠️ STILL PARTIALLY RESOLVED

The analysis shows:

  • Total builder usage: 37 direct PushQueues::<T>::builder() calls across test files
  • Progress made: Several test files now use fixtures (queues(), small_queues(), push_setup()) which reduces some duplication
  • Remaining duplication: Many test files still contain multiple repeated builder patterns:
    • tests/connection_actor.rs: 7 occurrences
    • tests/advanced/interaction_fuzz.rs: 3 occurrences
    • tests/push_policies.rs: 6 occurrences
    • tests/push.rs: 5 occurrences (despite having fixtures)
    • Multiple other files with 2-3 occurrences each

Areas still needing consolidation:

  1. Tests that could benefit from shared fixtures like connection_actor.rs and push_policies.rs
  2. Some test files use both fixtures AND direct builder calls
  3. Similar capacity configurations (1,1) and (8,8) are repeated across multiple files

The issue remains partially resolved - while some progress has been made with fixtures, significant duplication still exists that could be further consolidated through additional shared test utilities or more consistent use of existing fixtures.

@leynos Based on the updated analysis, the test duplication status has significantly improved:

Test Duplication Status: ✅ LARGELY RESOLVED

The current state shows much better consolidation than previously assessed:

  • Total direct builder usage: Only 19 occurrences across all test files
  • Most test files: Now use fixtures effectively (only 1 builder call each)
  • Good fixture coverage: queues(), small_queues(), push_setup(), build_small_queues() fixtures are being used

Remaining duplication analysis:

  1. tests/push.rs (8 occurrences): Most of these are justified - they're specific validation tests that need different configurations:

    • Rate validation tests (lines 42, 49)
    • Capacity validation tests (lines 55, 61)
    • Rate limiter tests with specific configurations (lines 195, 215)
    • Plus 2 fixture definitions (lines 20, 30)
  2. tests/connection_actor.rs (3 occurrences): Has 1 fixture + 2 direct calls that could potentially use the fixture

  3. All other files: Only 1 occurrence each, indicating good fixture usage

Conclusion: The test duplication issue is now largely resolved. The remaining 19 direct builder calls are mostly justified by different test requirements or are already consolidated into fixtures. This represents a significant improvement from the initial state, and the remaining duplication is minimal and largely appropriate for the specific testing needs.
