WalkthroughThe media service now resolves a bounded download timeout from an environment variable. It sends ChangesMedia download timeout and fallback
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to This change adds timeout and fallback controls for remote media downloads, but a slow or uncooperative server can still delay completion and prevent fallback because the local request has no deadline, while compatible remote handling is not yet available. The PR is not fully merge-ready until this availability risk is addressed or explicitly accepted. Suggested labels: Sequence Diagram(s)sequenceDiagram

For the Bun version declared by this repository, must expect(promise).rejects.() be awaited or returned for the test runner to await the assertion?
💡 Result:
Yes, in Bun's test runner, expect(promise).rejects.<matcher>() must be awaited for the assertion to be properly registered and executed [1][2]. Because expect(...).rejects returns a Promise that represents the eventual result of the assertion, failing to await it (or return it) in an asynchronous test will cause the test to complete before the assertion finishes, often leading to false positives where tests pass regardless of the rejection state [3][4]. Official documentation demonstrates this pattern by using the await keyword before the expect call when handling asynchronous errors [1][2]: ts test("should handle async errors", async () => { await expect(async () => { await fetchUser("invalid-id"); }).rejects.toThrow("User not found"); }); As noted in Bun's issue tracker, while the API is designed to be Jest-compatible, correct usage requires treating these assertions as asynchronous operations [3][4]. If you are working with a Promise directly, you should similarly await the chain [5][6]: ts await expect(Promise.reject("error")).rejects.toBe("error");

Bun test documentation Matchers rejects await return promise exact contract bun:test version-independent
💡 Result:
In Bun's built-in test runner (bun:test), the.rejects matcher is used to assert that a promise rejects [1][2][3]. When using this matcher, it is required to await the assertion to ensure the test correctly waits for the promise to settle before completing [1][3]. Correct usage involves awaiting the expect call: await expect(promise).rejects.toThrow; Or, when testing an asynchronous function directly: await expect(async => { await someAsyncFunction; }).rejects.toThrow("Error message"); Key points regarding this behavior: 1. Requirement to Await: Because.rejects returns a promise that resolves when the internal expectation is met (or rejects if it is not), you must use await. Failing to await the assertion will cause the test to finish prematurely, often resulting in false positives where the test passes regardless of the rejection state [1][3]. 2. Functionality: The.rejects matcher is part of the standard Matchers suite in bun:test and is designed to be compatible with common Jest-like testing patterns [3][4]. 3. Alternative Approaches: For more complex requirements, such as checking specific error properties,.rejects can be chained with other matchers like.toThrow [1][3]. You can also use expect.rejectsTo for specific asymmetric matching scenarios [5]. Bun's test runner is designed for performance and Jest compatibility, so these patterns align with standard expectations for asynchronous testing in the Node.js/JavaScript ecosystem [4][6].

Await each asynchronous rejection assertion.
The bun:test rejects matcher returns a promise. Without await or return, the test can finish before the matcher settles. Await each matcher.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Validate retry-delay environment values.
Number.parseInt returns NaN for invalid values and accepts malformed values such as "500ms". A negative maximum delay can also make retryDelayForAttempt return a negative value. The retry path then passes an invalid delay to sleep, which can disable the configured backoff.
Reject non-negative integer values at startup, as MAX_EVENT_RETRY already does.

Do not charge the retry budget during the duplicate check.
getLeastDepthEventForRoom increments persisted got before it returns an event. After an attempt fails, the next loop iteration selects the same event and increments got; Line 108 then detects the duplicate and breaks.
Each processing pass therefore consumes two retry counts for one actual processing attempt. With MAX_EVENT_RETRY = 10, only six processing attempts occur before a later pass sees got = 11 and unstages the event. Select unattempted events atomically before incrementing, or increment got only immediately before processing. Add a regression test that models the repository return-before-increment behavior.

The test comment claims the cap prevents a pass from outliving its watchdog, but the cap only bounds the overshoot.

P3: The expected values 500/1000/2000/4000/5000 and the 30_000 budget threshold only hold while FEDERATION_EVENT_RETRY_BASE_DELAY_MS and FEDERATION_EVENT_RETRY_MAX_DELAY_MS are unset. staging-area.service.ts reads both from process.env at module load, so setting either in the test/CI environment silently makes these assertions fail. Pin the env vars to their defaults at the top of the describe block (or set them to explicit values and assert against those) to make the tests deterministic.

P3: Wall-clock bounds make these timing tests flaky and environment-dependent. Test 4's >= 400 only holds if FEDERATION_EVENT_RETRY_BASE_DELAY_MS is at its default 500, and test 5's < 300 fails if a slow CI host takes longer than 300ms across two trivial mock iterations. Assert on the actual computed delay (e.g. verify retryDelayForAttempt(event.got) for the retry path, or inject/mock the sleep) instead of real elapsed time so the tests are deterministic and don't depend on env config or machine speed.

P3: The backoff sleep runs while the room lock is held and before the generator yields, but the queue watchdog (QUEUE_MAX_TIME_PER_ROOM, default 30s) only checks elapsed time after each yield. A pass can therefore outlive the watchdog by up to the sleep duration (5s), and the room stays locked during the sleep. The test comment claims the cap prevents a pass from outliving its watchdog, but the cap only bounds the overshoot. Consider sleeping after the yield so the watchdog can interrupt the pass before the delay, or document the bounded overshoot.

I looked at how synapse handles this and it is completely different.
since events can indeed come even before an upload starts, they fetch the upload when a client actually tries to see the actual upload, instead of fetching it in the exact moment the server receives the event.
I wonder how har would it be for us to do the same. hammering other servers with retries for something that is correctly not available yet doesn't seem to be a good solution, specially knowing it even contributes to rate limit.

The full fix will require a change in the Rocket.Chat repo as well (still preparing the PR).
