fix: make the request rate limits configurable - #323
Conversation
Bitween:RateLimits overrides the sign-in and per-account limits; defaults stay 10 and 600. Lets the local profile run the e2e suite, which spends the per-account budget several times over.

Reject non-positive rate-limit overrides.
PermitLimit must be greater than zero. A zero or negative value reaches partition creation on the first matching request, not during startup, and throws. SignInPerMinute affects sign-in requests. RequestsPerMinute affects all other requests.
Validate both values before registering the limiter, or define explicit behavior for disabling a limit.
Proposed validation
var requestLimit = limits.GetValue("RequestsPerMinute", 600);
+if (signInLimit <= 0 || requestLimit <= 0)
+ throw new InvalidOperationException("Rate limits must be greater than zero.");📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

The e2e suite runs as one account and spends the 600/min request budget several times over, so a random handful of tests failed every run with 429s.
Bitween:RateLimits:SignInPerMinute/RequestsPerMinuteoverride the limits. Defaults are unchanged (10 and 600) — verified the 11th sign-in still gets a 429 when unset.Full e2e suite: 155/155 locally with the limits raised in the Local profile.
