There was a problem hiding this comment.
Just checking - is this manifesting only on MacOS because a newer version of SQLite is being used there (i.e. by chance)?
Also, just noting that 0-reads (with TCP) are used as a way to ensure that the next read wouldn't block (i.e. that some amount of data has been received and is ready to be read synchronously). I don't think this is relevant for SQLite (as there's no networking involved), and in any case it seems that the SQLite APIs themselves don't support this.
