fix type_error with instantiated EOF -1 byte literal in get_byte/2
Markus Triska [Mon, 24 Oct 2022 17:18:49 +0000 (19:18 +0200)]
FIXED: CLP(ℤ): Correctly remove all attributes during propagation of all_distinct/1 and other global constraints.
The constraints from library(clpz) were already correctly removed, but
others such as pending freeze/2 goals were not, potentially leading to
an accumulation of redundant constraints during propagation.
Test case:
?- freeze(A,(X=1;X=2)), all_distinct([A]), A = 1.
A = 1, X = 1
; A = 1, X = 2.
The combination of freeze/2 and CLP(ℤ) is useful for example when
creating animations of search processes.

fix type_error with instantiated EOF -1 byte literal in get_byte/2
According to ISO Prolog, get_byte/2 predicate can receive an
instantiated input byte:
http://www.gprolog.org/manual/html_node/gprolog037.html#sec156
get_byte(+stream_or_alias, ?in_byte)
Since in_byte can be -1 if EOF is reached, instantiating it with -1
should work but does not because the implementation is trying to convert
it to a u8 which is unsigned:
?- open("/dev/null", read, S, [type(binary)]), get_byte(S, -1).
error(type_error(in_byte,-1),get_byte/2).
This commit adds an extra check for -1 before checking for a valid u8
instantiated value if in_byte is an input:
?- open("/dev/null", read, S, [type(binary)]), get_byte(S, -1).
S = '$stream'(0x55601e65c998).
