This changed the lines so the results now differ.
|
|
The function name can give information that the line number doesn't,
for example when using a parse transform that creates new functions.

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().

Update one more unused funs result as per ffe582b
Remove pubsub and comm_layer tests from testsuite

These tests recently broke because of the deprecation of the package system.
Furthermore, they included copyrighted code.
Finally they were not minimized not targeted to any specific feature and had no
warnings being reported.

Fix precision of record creation violation warnings

This patch enables Dialyzer to detect cases where a function has a specification
for a return type containing some list with elements different than the ones
Dialyzer's own algorithm can infer e.g. a function specified to return [atom()]
when actually [[atom()]] is returned.
Previously Dialyzer remained silent, under normal operation, seeing that these
two types have the empty list as a common element, so they were not 'completely
irrelevant'.
|
|
Before patch Dialyzer was reporting all the fields that were not subtypes
of the declared ones as incorrect. The correct violations are for the fields
whose intersection with the declared ones is empty.
|

Originally reported by Joseph Wayne Norton, simplified testcase provided by Hans
Bolinder.
|
|
Dialyzer no longer outputs warnings for unused anonymous functions
("funs"). Warnings are still output for unused functions.
Funs in functions with -nowarn_unused_function attributes generated
warnings for unused functions. Unused list comprehensions also
generated warnings for unused funs.

* sa/dialyzer-contract-variables:
Correct handling of type names in contracts
Don't rewrite unchanged PLT
Fix crash related to contract checking
OTP-10083
|
|
Variables in contracts can either be true type variables or simply names for
types thet are defined in the 'when' clauses. Consider the following example:
-spec foo(X, Options) -> {ok, X} | error when Options :: [{atom(), boolean()}].
Here X is a true variable whereas Options is a name for a type that is defined
in the when clause.
'when' clauses may further use names on the right side. These were not treated
properly by Dialyzer and could be generalized to the term() type. This patch
fixes this issue.
A further issue is the treatment of true type variables, but this is left for
another patch.

When spawning OS (unix) processes with erlang:open_port, store the
resulting unix pid so that it can be queried later on using
erlang:port_info/1,2.
|
|
Dialyzer was not reporting unused functions with 0 arity. This was not
a real issue, until we found out that there could be cases where this
could lead to false warnings. This was the case in "no_local_return.erl".
|
|
Whenever a variable that could hold one of two or more possible closures was
used in a particular application, the application was assumed to fail if ONE of
the closures would fail in this application. This has been corrected to infer
failing application if ALL possible closures would fail in the particular
application.
|
|
Dialyzer emits warnings like the following "The specification for _
states that the function might also return _ but the inferred return
is _", which are actually underspecifications and not wrong type
specifications. This patch makes sure that they are filed under the
appropriate category.
|
|
|
|
No warnings are emitted for funs that are non-returning when the
function that generates them has a contract that specifies that
it will return such a non-returning fun.
The actual bug, reported by Tuncer Ayaz and simplified by Maria
Christakis is included in Dialyzer's tests.
|
|
This patch makes Dialyzer aware of Erlang's total ordering of terms,
enabling discrepancy detection in cases where e.g. integer() < tuple()
is treated as a comparison that might also return false (when it is
certain to always return true).
