The scripts start it on a virtual display (Xvfb - Native HMAC supports only SHA-256; HMAC-SHA1 and HMAC-SHA512 go through `Hmac.generic`. - Function calls are expensive in the VM; hot loops inline small helpers (SHA-512 went 37 % faster that way). - The simulator doesn't enforce the watchdog in test runs. Anything long runs as a `Jobs.Job` with a bounded step. +- `StringUtil.convertEncodedString` stops the app with an uncatchable "System Error" on invalid UTF-8; `try` doesn't help. Decode untrusted bytes with `Bytes.toUtf8`, which validates first. +- `Application.Storage` stores ByteArrays (its `ValueType` includes them, unlike `Application.PropertyValueType`), so records are stored as single ByteArrays of known size. Dictionaries passed to it must be typed `Dictionary<Application.Storage.KeyType, Application.Storage.ValueType>`; `Dictionary<String, ...>` doesn't type-check. +- `Array.slice` returns `Array<Object or Null>`; cast it back (`as Array<String>`). ### Screenshots |
