Clamp setTimeout value to 32-bit integer (~25d) for `sleep()` by TooTallNate · Pull Request #824 · vercel/workflow

TooTallNate · 2026-01-21T17:35:23Z

Fix timeout overflow error in world-local queue implementation by clamping setTimeout values.

Fixes#823.

What changed?

Added a MAX_SAFE_TIMEOUT_MS constant (2147483647 ms, ~24.85 days) to prevent Node.js 32-bit integer overflow
Modified the setTimeout call in the queue retry logic to clamp timeout values to this maximum

How to test?

Create a workflow with a very long sleep duration (> 25 days)
Run it in local mode
Verify no "TimeoutOverflowWarning" appears in the logs
Confirm the sleep functionality still works correctly with the clamped values

Why make this change?

Node.js setTimeout uses a 32-bit signed integer internally, which means values larger than ~25 days cause overflow warnings. This change prevents those warnings while maintaining the correct behavior by allowing the handler to recalculate remaining time from persistent state when the clamped timeout fires. This is fine (using a value less than what the user requested) because the workflow handler logic will issue another queue call with timeoutSeconds if the desired date has not elapsed when the workflow is re-run.

TooTallNate · 2026-01-21T17:35:23Z

Fix timeout overflow error in world-local queue implementation by clamping setTimeout values.

Fixes#823.

What changed?

Added a MAX_SAFE_TIMEOUT_MS constant (2147483647 ms, ~24.85 days) to prevent Node.js 32-bit integer overflow
Modified the setTimeout call in the queue retry logic to clamp timeout values to this maximum

How to test?

Create a workflow with a very long sleep duration (> 25 days)
Run it in local mode
Verify no "TimeoutOverflowWarning" appears in the logs
Confirm the sleep functionality still works correctly with the clamped values

Why make this change?

Node.js setTimeout uses a 32-bit signed integer internally, which means values larger than ~25 days cause overflow warnings. This change prevents those warnings while maintaining the correct behavior by allowing the handler to recalculate remaining time from persistent state when the clamped timeout fires. This is fine (using a value less than what the user requested) because the workflow handler logic will issue another queue call with timeoutSeconds if the desired date has not elapsed when the workflow is re-run.

TooTallNate · 2026-01-21T17:35:23Z

Fix timeout overflow error in world-local queue implementation by clamping setTimeout values.

Fixes#823.

What changed?

Added a MAX_SAFE_TIMEOUT_MS constant (2147483647 ms, ~24.85 days) to prevent Node.js 32-bit integer overflow
Modified the setTimeout call in the queue retry logic to clamp timeout values to this maximum

How to test?

Create a workflow with a very long sleep duration (> 25 days)
Run it in local mode
Verify no "TimeoutOverflowWarning" appears in the logs
Confirm the sleep functionality still works correctly with the clamped values

Why make this change?

Node.js setTimeout uses a 32-bit signed integer internally, which means values larger than ~25 days cause overflow warnings. This change prevents those warnings while maintaining the correct behavior by allowing the handler to recalculate remaining time from persistent state when the clamped timeout fires. This is fine (using a value less than what the user requested) because the workflow handler logic will issue another queue call with timeoutSeconds if the desired date has not elapsed when the workflow is re-run.

TooTallNate · 2026-01-21T17:35:23Z

Fix timeout overflow error in world-local queue implementation by clamping setTimeout values.

Fixes#823.

What changed?

Added a MAX_SAFE_TIMEOUT_MS constant (2147483647 ms, ~24.85 days) to prevent Node.js 32-bit integer overflow
Modified the setTimeout call in the queue retry logic to clamp timeout values to this maximum

How to test?

Create a workflow with a very long sleep duration (> 25 days)
Run it in local mode
Verify no "TimeoutOverflowWarning" appears in the logs
Confirm the sleep functionality still works correctly with the clamped values

Why make this change?

Node.js setTimeout uses a 32-bit signed integer internally, which means values larger than ~25 days cause overflow warnings. This change prevents those warnings while maintaining the correct behavior by allowing the handler to recalculate remaining time from persistent state when the clamped timeout fires. This is fine (using a value less than what the user requested) because the workflow handler logic will issue another queue call with timeoutSeconds if the desired date has not elapsed when the workflow is re-run.

Clamp setTimeout value to 32-bit integer (~25d) for sleep() #824 👈 (View in Graphite)

TooTallNate · 2026-01-21T17:35:23Z

Fix timeout overflow error in world-local queue implementation by clamping setTimeout values.

Fixes#823.

What changed?

Added a MAX_SAFE_TIMEOUT_MS constant (2147483647 ms, ~24.85 days) to prevent Node.js 32-bit integer overflow
Modified the setTimeout call in the queue retry logic to clamp timeout values to this maximum

How to test?

Create a workflow with a very long sleep duration (> 25 days)
Run it in local mode
Verify no "TimeoutOverflowWarning" appears in the logs
Confirm the sleep functionality still works correctly with the clamped values

Why make this change?

Node.js setTimeout uses a 32-bit signed integer internally, which means values larger than ~25 days cause overflow warnings. This change prevents those warnings while maintaining the correct behavior by allowing the handler to recalculate remaining time from persistent state when the clamped timeout fires. This is fine (using a value less than what the user requested) because the workflow handler logic will issue another queue call with timeoutSeconds if the desired date has not elapsed when the workflow is re-run.

Clamp setTimeout value to 32-bit integer (~25d) for sleep() #824 👈 (View in Graphite)

TooTallNate · 2026-01-21T17:35:23Z

Fix timeout overflow error in world-local queue implementation by clamping setTimeout values.

Fixes#823.

What changed?

Added a MAX_SAFE_TIMEOUT_MS constant (2147483647 ms, ~24.85 days) to prevent Node.js 32-bit integer overflow
Modified the setTimeout call in the queue retry logic to clamp timeout values to this maximum

How to test?

Create a workflow with a very long sleep duration (> 25 days)
Run it in local mode
Verify no "TimeoutOverflowWarning" appears in the logs
Confirm the sleep functionality still works correctly with the clamped values

Why make this change?

Node.js setTimeout uses a 32-bit signed integer internally, which means values larger than ~25 days cause overflow warnings. This change prevents those warnings while maintaining the correct behavior by allowing the handler to recalculate remaining time from persistent state when the clamped timeout fires. This is fine (using a value less than what the user requested) because the workflow handler logic will issue another queue call with timeoutSeconds if the desired date has not elapsed when the workflow is re-run.

Clamp setTimeout value to 32-bit integer (~25d) for sleep() #824 👈 (View in Graphite)

TooTallNate · 2026-01-21T17:35:23Z

Fix timeout overflow error in world-local queue implementation by clamping setTimeout values.

Fixes#823.

What changed?

Added a MAX_SAFE_TIMEOUT_MS constant (2147483647 ms, ~24.85 days) to prevent Node.js 32-bit integer overflow
Modified the setTimeout call in the queue retry logic to clamp timeout values to this maximum

How to test?

Create a workflow with a very long sleep duration (> 25 days)
Run it in local mode
Verify no "TimeoutOverflowWarning" appears in the logs
Confirm the sleep functionality still works correctly with the clamped values

Why make this change?

Node.js setTimeout uses a 32-bit signed integer internally, which means values larger than ~25 days cause overflow warnings. This change prevents those warnings while maintaining the correct behavior by allowing the handler to recalculate remaining time from persistent state when the clamped timeout fires. This is fine (using a value less than what the user requested) because the workflow handler logic will issue another queue call with timeoutSeconds if the desired date has not elapsed when the workflow is re-run.

TooTallNate · 2026-01-21T17:35:23Z

Fix timeout overflow error in world-local queue implementation by clamping setTimeout values.

Fixes#823.

What changed?

Added a MAX_SAFE_TIMEOUT_MS constant (2147483647 ms, ~24.85 days) to prevent Node.js 32-bit integer overflow
Modified the setTimeout call in the queue retry logic to clamp timeout values to this maximum

How to test?

Create a workflow with a very long sleep duration (> 25 days)
Run it in local mode
Verify no "TimeoutOverflowWarning" appears in the logs
Confirm the sleep functionality still works correctly with the clamped values

Why make this change?

Node.js setTimeout uses a 32-bit signed integer internally, which means values larger than ~25 days cause overflow warnings. This change prevents those warnings while maintaining the correct behavior by allowing the handler to recalculate remaining time from persistent state when the clamped timeout fires. This is fine (using a value less than what the user requested) because the workflow handler logic will issue another queue call with timeoutSeconds if the desired date has not elapsed when the workflow is re-run.
