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.
2014-01-31Shut off a dialyzer unmatched return warningKostis Sagonas
Dialyzer does not like list comprehensions for which the result is not assigned to some variable (maybe anonymous). In this particular case, the comprehension, containing only a filter but no generator, was used to save some lines, but IMO this type of code, while "cute", is not so easy to comprehend.

* hb/dialyzer/opaque_types_fixes/OTP-10397: [dialyzer] Re-work the handling of opaque types
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.
2014-01-14Fix an erroneous specKostis Sagonas
The branch that patched this file to handle the new "named funs" added an extra argument to the main function of the module but forgot to update its spec.
2014-01-12fix -Wno_behaviours doc error in dialyzer man pageSteve Vinoski
The description of the -Wno_behaviours in the dialyzer man page incorrectly includes a "***" footnote marker, indicating that it's an option that turns on a warning rather than turning it off. Since the option actually turns off a warning, remove the marker. This fix makes the documentation match that obtained from dialyzer --help.

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.
2013-12-12Support non top level letrecs in dialyzerJosé Valim
Dialyzer so far only supported letrecs at the top-level and comprehension-like letrecs (i.e. that were directly applied) in their body. This commit address this issue by storing in the callgraph bound letrec labels pointing to their functions. This information is then used by the dataflow to properly lookup recursive definitions.

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.

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.
