* sa/dialyzer-contract-variables: Correct handling of type names in contracts Don't rewrite unchanged PLT Fix crash related to contract checking OTP-10083
2012-04-24Correct handling of type names in contractsStavros Aronis
Variables in contracts can either be true type variables or simply names for types thet are defined in the 'when' clauses. Consider the following example: -spec foo(X, Options) -> {ok, X} | error when Options :: [{atom(), boolean()}]. Here X is a true variable whereas Options is a name for a type that is defined in the when clause. 'when' clauses may further use names on the right side. These were not treated properly by Dialyzer and could be generalized to the term() type. This patch fixes this issue. A further issue is the treatment of true type variables, but this is left for another patch.

When "collapsing" heads of list elements from a list's tail into the list's head the new head can be different.

2012-04-17Extend erlang:port_info/1,2 to show the OS pid of a spawned processMatthias Lang
When spawning OS (unix) processes with erlang:open_port, store the resulting unix pid so that it can be queried later on using erlang:port_info/1,2.

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.

2012-02-22Avoid 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.

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".

2011-11-30Fix dialyzer warning about gen_event callback init/1 in log_mf_hSiri Hansen
The warning is about log_mf_h having a different spec for gen_event callback init/1 than defined in gen_event.erl. log_mf_h allows return value {error,Reason}, while gen_even only specifies successful return values. This commit add {error,Reason} as a valid return value to the gen_event callback, since this is handled by the code.
