2012-03-26Fix bug related with infinitely looping functionsStavros Aronis
Depending of the ordering of the functions during dataflow, a function with an infinite loop might be identified as one that always crashes. This is fixed now, by allowing restoration of the infinitely-looping status.
2012-03-26Report only actual unknown types otherwise no message is sentStavros Aronis

2012-02-22Refactorings in dialyzer_typesigStavros Aronis
2012-02-22Avoid unnecessary passing of huge terms in some closuresStavros Aronis
The relevant terms were instances of Dialyzer's typesig analysis state that were stored together with some "dynamic" constraints in a dict. Due to sharing this was not apparent until we tried to copy the dictionary. Initial debugging was by Björn Gustavsson.

Refactorings, code movements and reflection of mutable variables in the code.
2012-02-22Zero-arity unused functions Dialyzer patchStavros Aronis
Dialyzer was not reporting unused functions with 0 arity. This was not a real issue, until we found out that there could be cases where this could lead to false warnings. This was the case in "no_local_return.erl".

By keeping tracks of modified types the joining of maps ha become significantly faster.

2011-10-14Fix false warning about closure applicationStavros Aronis
Whenever a variable that could hold one of two or more possible closures was used in a particular application, the application was assumed to fail if ONE of the closures would fail in this application. This has been corrected to infer failing application if ALL possible closures would fail in the particular application.
2011-10-14Change category of 'might also return' warningsStavros Aronis
Dialyzer emits warnings like the following "The specification for _ states that the function might also return _ but the inferred return is _", which are actually underspecifications and not wrong type specifications. This patch makes sure that they are filed under the appropriate category.

2011-08-29Suppress some warnings about generation of non-returning funsStavros Aronis
No warnings are emitted for funs that are non-returning when the function that generates them has a contract that specifies that it will return such a non-returning fun. The actual bug, reported by Tuncer Ayaz and simplified by Maria Christakis is included in Dialyzer's tests.
