This document describes the changes made to the Dialyzer application.

+
Dialyzer 2.8 + +
Fixed Bugs and Malfunctions + + +

The translation of Erlang forms to the type + representation used by Dialyzer has been improved in + several ways. The most important change is that deeply + nested records can be handled.

+

+ Own Id: OTP-12350

+ + +

Fix a bug that could cause bogus warnings for opaque + types.

In Erlang/OTP 18 two parameterized types + declared in the same module always result in a + contradiction (none()) when combined outside of + the module where they are declared, unless they have the + same number of parameters.

The behaviour is + different from Erlang/OTP 17 where, for instance, + dict:dict() and dict:dict(_, _), which are + both opaque, can be combined outside of the dict + module.

In Erlang/OTP 18, dict:dict() and + dict:dict(_, _) can still be combined outside of + the dict module. That has been made possible by + not declaring dict:dict() as opaque.

+

+ Own Id: OTP-12493

+ + +

Update the PLT properly when a module is changed. + (Thanks to James Fish for the bug report, and to Stavros + Aronis for fixing the bug.)

+

+ Own Id: OTP-12637

+ + +

+ An argument of '*'/2 is not constraind if the other + operand can be zero.

+

+ Own Id: OTP-12725

+ + +

Mention the option check_plt among the + dialyzer:gui() options. (Thanks to James Fish.) +

+

+ Own Id: OTP-12750

+ + +

Fix a bug which could cause an infinite loop in + Dialyzer.

+

+ Own Id: OTP-12826

+ + +
+ + +
Improvements and New Features + + +

The -dialyzer() attribute can be used for + suppressing warnings in a module by specifying functions + or warning options. It can also be used for requesting + warnings in a module.

+

+ Own Id: OTP-10280

+ + +

The pre-defined types array(), dict(), + digraph(), gb_set(), gb_tree(), + queue(), set(), and tid() have been + removed.

+

+ Own Id: OTP-11445 Aux Id: OTP-10342, OTP-9352

+ + +

A few type names that have been used for representing + certain predefined types can now be used for user-defined + types. This affects the types product/_, + union/_, and range/2 as well as + tuple/N (N > 0), map/N (N > 0), + atom/1, integer/1, binary/2, + record/_, and 'fun'/_. A consequence is + that, for example, it is no longer possible to refer to a + record type with record(r); instead the usual + record notation, #r{}, is to be used.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+

+ Own Id: OTP-11851

+ + +

When implementing user-defined behaviours it is now + possible to specify optional callback functions. See OTP + Design Principles User's Guide, Sys and Proc_Lib, + User-Defined Behaviours, for details.

+

+ Own Id: OTP-11861

+ + +

Add two options to the Dialyzer: + no_missing_calls suppresses warnings about calls + to missing or unexported functions; unknown lets + warnings about unknown functions or types affect the exit + status. See also dialyzer(3).

+

+ Own Id: OTP-12682

+ + +

By default, dialyzer will now cache native versions of + dialyzer modules to avoid having to re-compile them each + time dialyzer is started. Caching can be disabled using + the option --no_native_cache.

+
