SANDBOX_OUTPUT_MAX_SIZEwithsafeInt, using 1024 when the value is invalid.Why
The current
Number(...)conversion turns a typo such asSANDBOX_OUTPUT_MAX_SIZE=bananaintoNaN. The runner uses this value in comparisons while streaming stdout and stderr. Every comparison withNaNis false, so the configured output cap is effectively disabled and output can keep accumulating in memory.The existing
safeInthelper already handles invalid, non-positive, and fractional values. This change uses that helper for the output limit only. Valid integer settings continue to work as before.Tests
bun test api/src/config.test.ts api/src/validation.test.tsbanana,-5,3.7, and2048through the config module.
