Add the mentioned test suites for *all* library and touched
non-library applications.

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.

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.

As discussed in issue #240 *all* OTP library applications use the '.*'
wildcard as up and down version. This makes library applications
always up- and downgradeable. Using the wildcard version obsoletes
all maintenance tasks regarding library applications' appup files.
Additionally, it prevents upgrade problems caused by automatically
included application dependencies when using reltool to create
releases. Missing copyright headers are now consistently present.

* kostis/dialyzer-r17c0-fixes:
Shut off a dialyzer unmatched return warning
Add a spec for a function that does not return
|
|
|

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.

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
|
|
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.
|
|
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.
|
|
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.

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.

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.

R17 will come without support for 'gs' so the old gs-based GUI of dialyzer
has been removed.

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.

It makes no sense to be able to do `<<...,Rest/binary>> <= ...` in a
