* bjorn/lc-warnings/OTP-11626: dialyzer: Silence useless warnings about list comprehensions
2014-02-06Add app-test and correct dialyzer.app.srcHans Bolinder
2014-02-05dialyzer: Silence useless warnings about list comprehensionsBjörn Gustavsson
Dialyzer will warn if the value of list comprehension is ignored by putting it in a sequence like this: [SomeSideEffect(E) || E <- Es], ok To avoid a warning, you'll have to write: _ = [SomeSideEffect(E) || E <- Es], ok Most of the time, this warning is merely annoying because it does not point out any real errors. Kostis Sagonas suggested that by suppressing the warning for list comprehension that return a list of a simple type (e.g. ['ok']), there would be no warning for code such as: [io:format("~p\n", [E]) || E <- Es], ok but there would be still be a warning for: [file:close(Fd) || Fd <- Fds], ok because an error condition is ignored.

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.

2013-12-12EEP 37: Funs with namesAnthony Ramine
This adds optional names to fun expressions. A named fun expression is parsed as a tuple `{named_fun,Loc,Name,Clauses}` in erl_parse. If a fun expression has a name, it must be present and be the same in every of its clauses. The function name shadows the environment of the expression shadowing the environment and it is shadowed by the environment of the clauses' arguments. An unused function name triggers a warning unless it is prefixed by _, just as every variable. Variable _ is allowed as a function name. It is not an error to put a named function in a record field default value. When transforming to Core Erlang, the named fun Fun is changed into the following expression: letrec 'Fun'/Arity = fun (Args) -> let <Fun> = 'Fun'/Arity in Case in 'Fun'/Arity where Args is the list of arguments of 'Fun'/Arity and Case the Core Erlang expression corresponding to the clauses of Fun. This transformation allows us to entirely skip any k_var to k_local transformation in the fun's clauses bodies.

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.

files as delimiters. While working on a tool that processes Erlang code and testing it against this repo, I found out about those little sneaky 0xff. I thought it may be of help to other people build such tools to remove non-conforming-to-standard characters.
2013-09-05Fix httpd config option 'script_timeout'Johannes Weißl
This fixes the usage of the httpd configuration option 'script_timeout', which got ignored before. The documentation states that the value is in seconds, which was true when using the Apache like configuration file, but not true when using the proplist style configuration.
2013-06-05Forbid unsized fields in patterns of binary generatorsAnthony Ramine
It makes no sense to be able to do `<<...,Rest/binary>> <= ...` in a comprehension. The related Dialyzer test is removed.

2013-04-17Encode Erlang source files with non-ascii characters in UTF-8Björn Gustavsson
To ensure that 'master' compiles when we merge 'maint' to it, regardless of which encoding is default in 'master', all source files with non-ascii characters *must* have the encoding specified.
2013-04-08Fix an error in the type inference of bitstring dataStavros Aronis
Dialyzer was constraining bitstring data used in the construction of other bitstring values too much. These constraints have now been relaxed.
2013-03-06Include module, function and arity in Dialyzer's "overlapping domain" warningsMagnus Henoch
The function name can give information that the line number doesn't, for example when using a parse transform that creates new functions.

2013-02-13Make the file:filename() type more restrictiveBjörn Gustavsson
The recommended type for filenames is a list of characters (which may be Unicode characters greater than 255). Change the file:filename() to reflect that. For the filename module we still need a type that can be either a string or a binary, so we need to introduce the type file:filename_all().

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.
