2014-03-24hipe: Correct last commit of OTP-10342Hans Bolinder
Remove debug printouts.
2014-03-24stdlib: warn if the type map() is redefinedHans Bolinder
2014-03-24hipe: Add a few clauses for maps in erl_typesHans Bolinder
2014-03-17hipe: Properly identify map() type form termsBjörn-Egil Dahlberg
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.
2014-02-22Introduce parameterized opaque typesHans Bolinder
Handle immediate opaque types as aliases: A declaration of dict/0 -opaque dict() :: dict(_, _). -opaque dict(Key, Value) :: ... is handled as an alias, that is, when using dict() it is immediately replaced by dict(_, _). This is a means to avoid having to handle equivalent opaque types later. To be changed if it doesn't work well.
2014-02-22Fix a bug concerning parameterized typesHans Bolinder
This should fix a problem with variables in parameterized types. In particular it concerns parameterized opaque types and records.

2014-01-28dialyzer,hipe,stdlib: Add Maps understanding to DialyzerBjörn-Egil Dahlberg
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.
2013-10-09Fix crash when using remote types in the tail of list typesKostis Sagonas
Hans Bolider reported a dialyzer crash when using a remote type in the tail position of a maybe_improper_list() declaration. A test was created (by extending an existing module of the testsuite) and erl_types was modified to expand the remote type and not pass it unexpanded to subsequent phases in the processing.

2013-01-25Extend char() to Unicode charactersHans Bolinder
The code related to the introduction of unicode_string() and unicode_char() has been removed. The types char() and string() have been extended to include Unicode characters. In fact char() was changed some time ago; this commit is about cleaning up the documentation and introduce better names for some functions.
2013-01-23Properly support functions with arbitrary arity in type specs.Stavros Aronis
Dialyzer now understands the "fun(...)" syntax in type specs.
2012-11-17Fix precision of record creation violation warningsStavros Aronis
Before patch Dialyzer was reporting all the fields that were not subtypes of the declared ones as incorrect. The correct violations are for the fields whose intersection with the declared ones is empty.
2012-09-26Fix handling of tuple set remote types appearing in tuple setsStavros Aronis
Originally reported by Joseph Wayne Norton, simplified testcase provided by Hans Bolinder.

2012-08-21Let t_inf() substitute any() for variables in a few more casesHans Bolinder
The clauses handling opaque types haven't been fixed here.
2012-04-24Fix crash related to contract checkingStavros Aronis
When "collapsing" heads of list elements from a list's tail into the list's head the new head can be different.

2011-12-08Optimize erl_types:t_unify()Hans Bolinder
Using a list rather than a dict() for unified variables saves quite some time. In particular Dialyzer is a heavy user of t_unify().
2011-12-01Fix crash in DialyzerStavros Aronis
Variable substitution was not generalizing any unknown variables.

2011-09-16Quote atoms if necessary in typesTomas Abrahamsson
Atoms in some occurrences were not correctly quoted when formatted to strings, for instance by the typer program. Example: -module(tb). -export(['UPPERCASE-FUNCTION-NAME'/0, f1/0, f2/0, f3/0]). -record('UPPERCASE-RECORD-NAME', {x}). -record(r2, {'UPPERCASE-FIELD-NAME'}). -type 'UPPERCASE-TYPE-NAME'() :: integer(). 'UPPERCASE-FUNCTION-NAME'() -> ok. f1() -> #'UPPERCASE-RECORD-NAME'{x=1}. f2() -> #r2{'UPPERCASE-FIELD-NAME'=1}. -spec f3() -> 'UPPERCASE-TYPE-NAME'(). f3() -> 1. Given the program above, the output from typer --plt some.plt tb.erl resulted in the following specs being printed: -spec UPPERCASE-FUNCTION-NAME() -> 'ok'. -spec f1() -> #UPPERCASE-RECORD-NAME{x::1}. -spec f2() -> #r2{UPPERCASE-FIELD-NAME::1}. -spec f3() -> UPPERCASE-TYPE-NAME(). This commit changes the output to become the following: -spec 'UPPERCASE-FUNCTION-NAME'() -> 'ok'. -spec f1() -> #'UPPERCASE-RECORD-NAME'{x::1}. -spec f2() -> #r2{'UPPERCASE-FIELD-NAME'::1}. -spec f3() -> 'UPPERCASE-TYPE-NAME'().

2010-12-13Fix native code compiler infinite loop and update type info for 're'Kostis Sagonas
The introduction of filenames being unicode binaries revealed a problem in the type analysis of the native code compiler which resulted in an infinite loop when compiling the 'filename' module. In addition, the hard-coded type information for the built-in functions of the 're' module was out-of-date, which resulted in erroneous type information for 'filelib' functions being stored in the PLT.
2010-11-22erl_types: Fix pretty rare crashes and an infinite loopKostis Sagonas
- Fixed pretty rare crash when taking the infimum of two tuple_sets (initial fix by Kostis Sagonas but then a better fix was provided by Stavros Aronis and this is the one adopted). - Fixed pretty rare crash when using parameterized types containing unbound variables (thanks to Nicolas Trangez for reporting it). - Fixed pretty rare infinite loop when refining the types of an SCC whose functions all returned none() (thanks to Stavros Aronis).
2010-10-29Deeper unfolding of recursive typesKostis Sagonas
The change of taking out some hard-coded information about the file module uncovered that the unfolding of recursive types was probably too shallow. This has been fixed by unfolding it until a deeper limit (REC_TYPE_LIMIT). While at erl_types.erl also did some cleanup changes and fixed an erroneous io:format message.
2010-09-24Fix two errors in dialyzerKostis Sagonas
Changes which fix some problems reported by dialyzer users: 1. The handling of nested opaque types 2. The handling of remote types in record expressions used as types While at it, updated dialyzer's RELEASE_NOTES to reflect these fixes and did some cleanups to dialyzer_utils.erl so that it gets in sync with dialyzer's main development branch.
