The clauses handling opaque types haven't been fixed here.
|
|
When "collapsing" heads of list elements from a list's tail into the list's
head the new head can be different.

Using a list rather than a dict() for unified variables saves quite
some time. In particular Dialyzer is a heavy user of t_unify().
|
|
Variable substitution was not generalizing any unknown variables.

This fixes a memory related crash.

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'().

Same functionality provided by string:join/2.

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of the 're' module was out-of-date, which resulted in erroneous type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.

- 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).

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.

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.
|
|
Bumped version number and wrote RELEASE_NOTES.
Included all changes described in release notes.
Some spec-related changes to some files in lib/hipe/cerl.
|
|
It is useful for testing.

When defining macros the closing right parenthesis before the dot is now
mandatory.
