Markus Triska 1967518fa2 FIXED: documentation of countall/2 (#1976) 2023-09-05 19:42:55 +02:00
Bennet Bleßmann 5928d64d7a make F64Table concurency safe 2023-09-05 19:39:59 +02:00
Bennet Bleßmann c7ec5a13a5 remove locks from AtomTable 
there are technically still two locks
- the Mutex to serialize consurrent updates to the AtomTable
- the RwLock as part of GLOBAL_ATOM_TABLE

the former is the age lock of RESIZE ATOM TABLE in <https://arxiv.org/pdf/1608.00989.pdf>, though we use it for the whole update as we don't match the whole structure and can't reserve an atom slot as is, so we need to also lock concurrent updates without resizing

the later should be uncontendet as we only write AtomTable::new iff the current value is a dangling Weak

FIXED: make occurs_check and answer_write_options flags discoverable
 2023-09-03 18:39:24 -06:00
Markus Triska aca0de06cd FIXED: make occurs_check and answer_write_options flags discoverable 
Quoting from 7.11 Flags:

   NOTE - A built-in predicate current_prolog_flag(Flag, Value)
   (8.17.2) enables a program to discover all the flags supported
   by a processor and their current values.

Markus Triska 98086de77e attach more propagators before starting propagation 
This prevents repeated triggering of already attached propagators
while new propagators are being attached to involved variables.

Markus Triska 24456e9703 remove optional (+)/1 prefix in get_atts/2 and put_atts/2 calls 
The (+)/1 prefix in get_atts/2 at line 4219 by itself already causes a
greater than 15% slowdown for the benchmark shown in #1730:

    ?- N #= 2^14,
       time(((between(1, N, _),
              X #\= Y,
              false)
            ; true)).

The performance impact is not a good reason to remove the optional
(+)/1 prefix! Performance issues should be addressed at the root, in
this case get_atts/2 (#1962). We should never manually work around
performance issues in built-in predicates.

In contrast, readability is a good argument, and I find the calls
slightly easier to read without the optional (+)/1 prefix.

The prefix is now consistently omitted when possible.
