If your stream mode virtual table stalls in it's xNext method until the next
row from the stream is available (or the stream is closed, in which case it
needs to set an EOF flag for the xEof method to return), then each row will be
aggregated as it becomes available. The result will not be avail
NUL is a valid utf8 character
but FF is never valid. (would be like a 36 bit length specification)
and practically anthing more than F8 is invalid utf8 character.

The patch focuses on problems with TEXT=>NUM conversions. The sole

Cezary. Your short form fix for the spurious NUMERIC CAST due to trailing
space was definitely received in your original posting.

IMO, simple INT saturation is not convenient for easy

Sqlite aggregation functions receive one call for each row in the underlying
results set. Has anyone on the list done a virtual table that's a based on a
stream?
Something conceptually along the lines of
Insert row a
Insert row b
begin aggregation on rows a, b
insert row c
insert row d

Confirmed.

AFAIK, SQLite uses max of 64-bit integer math, not 128.

Thank you Simon, I totally understand you.
And still hope for someone to give me some advice about my wal+mmap (Map
file when opening it and do not truncate the file) .
Thanks.
