It is allowed in Erlang/OTP 17 to redefine the map() types. However,
Dialyzer did not handle local map() types correctly.
|
|
The -dialyzer() attribute can be used for suppressing warnings in a
module by specifying functions or warning options. It can also be used
for requesting warnings in a module.

Correct a bug introduced in commit 8498a3.
|

After introducing maps for supervisor flags and child specs two tests
in behaviour_SUITE started failing:
behaviour_SUITE:custom_sup - failed because the type of the Period
(MaxT) property had been changed (corrected) from non_neg_integer() to
pos_integer() in the specification of the init callback in
supervisor.erl
behaviour_SUITE:supervisor_incorrect_return - same as above, plus the
introduction of #{} as possible value for the supervisor flags and
child_specs.

Sometimes bogus warnings were generated for parametrized types.
Thanks to Krzesimir Sarnecki for pointing the bug out.
Also corrected warnings where the structure of opaque types were

Fetch the compile options from beam files, and use them when creating
core from the abstract code. Previously the options were ignored.

[dialyzer] Use the option 'dialyzer' to control the compiler
[dialyzer] Fix handling of literal records
|
|
This ticket is about records in Erlang code, and when to check the
fields against the (optional) types given when defining records.
Dialyzer operates on the Erlang Core format, where there are no trace
of records. The fix implemented is a Real Hack:
Given the new option 'dialyzer' erl_expand_records marks the line
number of records in a way that is undone by v3_core, which in turn
inserts annotations that can be recognized by Dialyzer.

hipe: fix a bug concerning typed record fields

When checking typed record fields Dialyzer failed to handle
types containing remote types.
Thanks to Erik Søe Sørensen for reporting this bug.

|
The pre-defined types array(), dict(), digraph(), gb_set(), gb_tree(),
queue(), set(), and tid() have been removed.

Dialyzer sometimes output warnings like
Attempt to test for inequality between a term of type 'false' and a
term of opaque type 'false' | gb_set()
The reason was that erl_types:t_inf/3 when called from
erl_types:t_find_unknown_opaque() did not return 'false' but found the
mismatch. It should not return the mismatch unless the intersection is
empty ('none').
Thanks to Shayan Pooya [[email protected]] for pointing out the bug.

Two steps are needed to make this work:
1) Avoid generating the additional "apply_constraint" in dialyzer_typesig by
reporting every function argument as a potential external function (patch on
dialyzer_dep).
This will produce correct success typings for all functions in the test case,
but dataflow would miss the key warnings that help identify the bugs.
2) Patch dialyzer_dataflow so that it uses the "handle just external" path as a
fallback whenever there are any external calls. As a result, if we have info
about some paths, then:
a) use the old "handle known apply" code to mark these functions as used and
b) ignore the generalized result and use the one found by typesig for the
return value of the apply itself.

Don't 'opaque-decorate' a success typing using an incompatible spec
|
|
Without this patch Dialyzer crashes when analyzing the supplemented test case.
|
|
|
|
Guard constraints used to be limited to a certain depth, which handled
mutually depending constraints safely, but also sometimes introduced
unnecessary generalizations.
This patch puts no explicit limit upon guard constraints (other than
those that already exist in erl_types), but breaks cycles by replacing
variables with the any() type.
In some cases the old method resulted in more warnings, but since the
limit was quite arbitrary and mutually depending guard constraints are
(very) rare, the new method should been seen as an improvement since
it handles cases that used to make Dialyzer loop or miss warnings.

UTF-8 is now the default encoding and should no longer be

coding statement was missed.

[pull request from Kostis Sagonas]
The handling of functions appearing in an 'on_load' attribute was wrong.
Instead of considering the functions specified in these attributes as
escaping from the module and performing a full analysis starting from
them, the code just bypassed this analysis and only suppressed unused
warning messages for these functions. This worked for most of the cases
but resulted in functions (directly or indirectly) called by 'on_load'
functions being reported as not called by the module.
Such a case existed in the code of the 'crypto' application.
To solve these issues the initialization code for functions escaping
from the module was changed and the test for the on_load functionality
was appropriately extended.

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.

* bjorn/lc-warnings/OTP-11626:
dialyzer: Silence useless warnings about list comprehensions
|
|
|
|
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.

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.

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.
