2016-05-13Fix dependency calculation when encountering an erroneous 'apply'Kostis Sagonas
Dialyzer's dependency calculation was throwing an error when encountering an 'apply' node with something that was not a variable (e.g., a literal). The rest of the code did not know what to do with this error, which resulted in dialyzer crashing. Fix this by ingoring the detected error in the dependency calculation phase; later dialyzer passes know how to properly handle and report this kind of errors anyway. This fixes [Erlang-JIRA] (ERL-138).

2014-03-28Dialyzer now plays nicely with funs that come as "external" argumentsStavros Aronis
Two steps are needed to make this work: 1) Avoid generating the additional "apply_constraint" in dialyzer_typesig by reporting every function argument as a potential external function (patch on dialyzer_dep). This will produce correct success typings for all functions in the test case, but dataflow would miss the key warnings that help identify the bugs. 2) Patch dialyzer_dataflow so that it uses the "handle just external" path as a fallback whenever there are any external calls. As a result, if we have info about some paths, then: a) use the old "handle known apply" code to mark these functions as used and b) ignore the generalized result and use the one found by typesig for the return value of the apply itself.

* hb/dialyzer/fix_on_load/OTP-11743: FIx handling of 'on_load' attribute
2014-02-24FIx handling of 'on_load' attributeHans Bolinder
[pull request from Kostis Sagonas] The handling of functions appearing in an 'on_load' attribute was wrong. Instead of considering the functions specified in these attributes as escaping from the module and performing a full analysis starting from them, the code just bypassed this analysis and only suppressed unused warning messages for these functions. This worked for most of the cases but resulted in functions (directly or indirectly) called by 'on_load' functions being reported as not called by the module. Such a case existed in the code of the 'crypto' application. To solve these issues the initialization code for functions escaping from the module was changed and the test for the on_load functionality was appropriately extended.
2014-02-23Deprecate pre-defined built-in typesHans Bolinder
The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(), set(), and tid() have been deprecated. They will be removed in OTP 18.0. Instead the types array:array(), dict:dict(), digraph:graph(), gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid() can be used. (Note: it has always been necessary to use ets:tid().) It is allowed in OTP 17.0 to locally re-define the types array(), dict(), and so on. New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2, queue:queue/1, and sets:set/1 have been added.

The branch that patched this file to handle the new "named funs" added an extra argument to the main function of the module but forgot to update its spec.
2013-12-12Support non top level letrecs in dialyzerJosé Valim
Dialyzer so far only supported letrecs at the top-level and comprehension-like letrecs (i.e. that were directly applied) in their body. This commit address this issue by storing in the callgraph bound letrec labels pointing to their functions. This information is then used by the dataflow to properly lookup recursive definitions.
