2016-11-22dialyzer: Substitute 'opacity' for 'opaqueness'Hans Bolinder
Suggested by Kostis.
2015-06-15dialyzer: Modify warning for comparison of opaque typesHans Bolinder
Comparing two operands for (in)equality is allowed if both operands are of the same unknown opaque type. Since OTP 17, there is a warning if the types of the operands have nothing in common (this cannot happen before OTP 17). However, the warning says there is a test between opaque types, which is wrong. The warning now states that the comparison cannot evaluate to 'true', which is more consistent.
2014-06-17[dialyzer] Fix handling of literal recordsHans Bolinder
This ticket is about records in Erlang code, and when to check the fields against the (optional) types given when defining records. Dialyzer operates on the Erlang Core format, where there are no trace of records. The fix implemented is a Real Hack: Given the new option 'dialyzer' erl_expand_records marks the line number of records in a way that is undone by v3_core, which in turn inserts annotations that can be recognized by Dialyzer.
2014-01-21[dialyzer] Re-work the handling of opaque typesHans Bolinder
It is now OK to inspect and modify the internals of opaque types within the scope of the module. The contracts are used for decorating types with opaqueness when it is harmless to do so. The opaqueness is propagated by the typesig module and also by the dataflow module. A lot of details have been fixed or updated. In particular the modules erl_types and erl_bif_types have been modified extensively. The version in vsn.mk has been updated to 2.7. The reason is a modification of #opaque{} in erl_types. Dialyzer seems to be about five percent slower than it used to be.
