Description

fix: cap API retry exponential backoff at 10 minutes maximum

Files affected:

• src/core/task/Task.ts

Issue:
Auto-retry feature with exponential backoff was causing excessive delays
that could reach multiple hours (e.g., 7168 seconds ≈ 2 hours) when API
requests repeatedly failed. This particularly affected users working with
frequently overloaded models like Gemini 2.0 Thinking that return 503
"model overloaded" errors.

Root cause:
The retry logic used unbounded exponential backoff with formula:
baseDelay * 2^retryAttempt. With a 7-second base delay, this resulted
in delays growing as: 7s → 14s → 28s → 56s → ... → 7168s after 11 failures.

Solution:
Added Math.min() cap of 600 seconds (10 minutes) to the exponential delay
calculation. This preserves the benefits of exponential backoff for
transient errors while preventing excessive delays that could abandon
long-running tasks.

Impact:

• Maintains exponential backoff benefits for short-term outages
• Prevents "all night prompts" from getting stuck for hours
• Only affects auto-retry with alwaysApproveResubmit enabled
• Does not impact 429 rate-limit handling or manual retry flows

Test Procedure

• Set a AI profile config with an invalid URL (can be something random like "aisdaujdshfjgsd.com")
• Set auto-approve retry
• Check if the retry time goes to at most 10 minutes. The logic that was implemented before doubled the time after every retry, I set a hard cap to at most 10 minutes.

Additional Notes

Should I set a configuration for the max delay time? Or change the limit for something other than 10 minutes?

Important

Caps API retry exponential backoff at 10 minutes in Task.ts to prevent excessive delays.

• Behavior:
  • Caps exponential backoff for API retries at 600 seconds (10 minutes) in Task.ts.
  • Affects auto-retry logic with alwaysApproveResubmit enabled.
• Logic:
  • Uses Math.min() to limit delay calculation in attemptApiRequest().
  • Does not affect 429 rate-limit handling or manual retries.
