These functions will fall back to
enabled/3
if not provided and the tracepoint is active.

* hasse/dialyzer_fix_from_form/OTP-13520:
dialyzer: Fix a bug in the translation of forms to types
|
|
A bug is fixed, but there are more problems.
Modify erl_types.erl like this:
-define(EXPAND_LIMIT, 500).
and bogus warnings are output (again).
Callbacks and specs are compared (subtype) in dialyzer_behaviour. If
they are expanded to different depths, then invalid warnings can be
generated.

'...' is allowed at the end of of association types.

Type information is stored in erl_bif_types for certain BIFs.
This fact must be stated in the type specification for the
stubs that are superceded by erl_bif_types.
* Shadowed by erl_bif_types: maps:from_list/1

Opaque singleton keys have the unfortunate property, unlike any other
singleton type, to overlap with other singleton types that do not have
the same internal representation. Therefore, we must not keep opaque
singletons in the Pairs list in a map type.

t_subtract/2 would break its postcondition by always returning the
underapproximation none() when given a variable on the right hand side.
This broke map type parsing, since it relied on t_subtract/2 to tell it
when map keys would shadow each other.
