2016-05-04runtime_tools: Add send tpe testcaseSverker Eriksson
2016-05-04runtime_tools: Add dbg functions tpe/2 and ctpe/1Sverker Eriksson
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,...).

2016-04-29dialyzer: Fix a bug in the translation of forms to typesHans Bolinder
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.

2016-04-28stdlib: Add shadow comments for BIFs in mapsBjörn-Egil Dahlberg
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 This fact must be stated in the type specification for the stubs that are superceded by erl_bif_types.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 * Shadowed by erl_bif_types: maps:get/2 * Shadowed by erl_bif_types: maps:is_key/2 * Shadowed by erl_bif_types: maps:merge/2 * Shadowed by erl_bif_types: maps:put/3 * Shadowed by erl_bif_types: maps:to_list/1 * Shadowed by erl_bif_types: maps:update/3

2016-04-28erl_types: Don't consider opaque keys singletonMagnus Lång
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.
2016-04-28erl_types: Fix t_subtract/2 correctness bugMagnus Lång
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.
2016-04-28erl_types: Fix crash merging maps with opaque keysMagnus Lång
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.
2016-04-28dialyzer_typesig: Fix bad external typeMagnus Lång
28a4a5057ab9 mistakenly used the non-existing type cerl:tree() instead of cerl:cerl().
2016-04-28dialyzer: Fix another pattern literal bugMagnus Lång
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.
2016-04-28Bump Dialyzer versionMagnus Lång
Because the type representation has changed, old PLTs are not compatible. We update the version to 2.10 because of this.
2016-04-28dialyzer: Improve map pattern typesettingMagnus Lång
2016-04-28dialyzer_contracts: Consider #{} a violationMagnus Lång
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.
2016-04-28dialyzer_typesig: Fix simplification bugMagnus Lång
mk_constraint_list/2 was simplifying (C OR TriviallyTrue) to (C), which is obviously wrong.
2016-04-28dialyzer_dataflow: Fix try in guardsMagnus Lång
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.
2016-04-28dialyzer: Unfold cerl patterns containing mapsMagnus Lång
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.

2016-04-28Enhance map specs in erts, stdlib, runtime_toolsMagnus Lång
Using the new type syntax, we can specify which keys are required, and which are optional in a way Dialyzer could use.
2016-04-28erl_parse: Add parsing for new map type syntaxMagnus Lång
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.
