i.e enable all send/receive trace.
|

|

|
|
To set/clear match specs for send and receive trace.
'e' for Event as we might want to add match specs
for other trace events (proc exit,link,ulink,...).

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stubs that are superceded by erl_bif_types.

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.
|
|
Opaque keys in maps broke an assumption in
erl_types:mapmerge_otherv/3 (that the infinimum of a singleton type and
some other type would either be none() or that same singleton type),
causing a case_clause crash.

28a4a5057ab9 mistakenly used the non-existing type cerl:tree() instead
of cerl:cerl().
|
|
dialyzer_typesig:traverse/3 would perform an unsafe optimisation when
given a cons pattern that contained a map and could be folded into a
literal with cerl:fold_literal/1. In this case, when traversing the map
a type variable would be generated, but this variable would be dropped
by the erl_types:t_cons/2 constructor by in turn calling t_sup(),
producing the overapproximation any(). However, in this particular case,
dialyzer_typesig:traverse/3 is not allowed to overapproximate, since its
result is used in an EQ-constraint.
Although erl_types:t_tuple/1 does not overapproximate like t_cons/2,
which makes the bug unlikely to affect tuples too, the fix was
nevertheless applied defensively to the case of tuples as well.
Also, fix a bug where dialyzer_utils:refold_pattern/1 would generate
syntax nodes with two {label, _} attributes.

Because the type representation has changed, old PLTs are not
compatible. We update the version to 2.10 because of this.

This is analogous to the case of nil. Since #{} is a base-case of almost
all map types, contract and success typing sharing #{} does not mean
much, and is often sign of a violation.
|

mk_constraint_list/2 was simplifying (C OR TriviallyTrue) to (C), which
is obviously wrong.
|
|
The assumption that 'try' nodes were only used to wrap entire guards is
no longer true.
We're still swallowing warnings when the handler returns successfully.
Unfortunately, bind_guard/5 would need to be refactored to return a new
state in order to generate those warnings.
|
|
Dialyzer relies heavily on the assumption that the type of a literal
that is used as a pattern is the type of any value that can match that
pattern. For maps, that is not true, and it was causing bad analysis
results. A new help function dialyzer_utils:refold_pattern/1 identifies
maps in literal patterns, and unfolds and labels them, allowing them to
be properly analysed.
|
|
|
|
|
|
Using the new type syntax, we can specify which keys are required, and
which are optional in a way Dialyzer could use.
|
|
erl_types typesets mandatory keys with :=, and uses "..." as a shorthand
for "any() => any()". Add these to erl_parse so that all representable
types can be written in type-specs.
