Ok, I'm back to fixing all the 64 bit off_t discrepancies in APR/Apache. Can we basically agree that a "Bucket" can never be bigger than apr_ssize_t? I've no problems with using apr_off_t for the length of a full Brigades itself. That means we can split a brigade on any apr_off_t, but would only need to split a bucket on an apr_ssize_t. It implies a 'Pipe' bucket can't generate more than 2^31 bytes without breaking the code.
This means a huge file would need to be split by the caller into multiple file buckets, no longer than ssize_t. Is this reasonable? Bill
