Try write directly to process heap (as before)
if the term is guaranteed not to contain any
big maps that may break the initial size estimation.
|
|
The test cases does not use any hooks and including the ts_install_cth
trips up the test case setup on some platforms cuasing the test cases
to fail with {error, enoent}

by adding a dynamic heap factory.
"binary_to_term" is now a hybrid solution with both
a call to decoded_size() to calculate needed heap space
AND possible dynamic allocation of more heap space
if needed for big maps.
The heap size returned from decoded_size() is guaranteed
to be sufficient for all term heap data except for hashmap
nodes. All hashmap nodes are created at the end of dec_term()
by invoking the heap factory interface that may allocate more
heap space on process heap or in fragments.
With this commit it is no longer guaranteed that a message
is confined to only one heap fragment.

to be better at reusing entire hashmap sub-trees.
Sub-tree reuse is detected in three cases:
1. The sub-tree top node does not exist at all in the other map.
Already implemented before this commit.
2. The exact same sub-tree exist in both maps.
Must calculate nr of keys in tree to get total size right.
3. We detect that a sub-tree only contains stuff from one of the maps.
There is still one case we don't detect. If A and B leafs have equal
keys we could also compare the values. If values are equal, further
node reuse could propagate up toward the root (by 'mix'==0).
The downside would be potentially expensive value comparisons.

* hb/dialyzer/fix_opaque_types/OTP-12493:
dialyzer: Fix a minor bug concerning opaque types
dialyzer: Modify warning for comparison of opaque types
dialyzer: Modify the handling of parametrized opaque types
|
|
The test t_is_none() does not check for opaque types (and this is most
likely how it should be), why t_opaque() should never be called with
none().
|
|
Comparing two operands for (in)equality is allowed if both operands
are of the same unknown opaque type. Since OTP 17, there is a warning
if the types of the operands have nothing in common (this cannot
happen before OTP 17). However, the warning says there is a test
between opaque types, which is wrong. The warning now states that the
comparison cannot evaluate to 'true', which is more consistent.
|
|
In OTP 17 it is possible to mix types such as dict:dict() and
dict:dict(_, _) outside of the dict module (and similarly for some
other opaque types in STDLIB), but the results are unfortunately
possibly invalid warnings in users' code. In OTP 18 parameterized
opaque types with the same name but with different number of
parameters are no longer compatible when seen from outside of the
module where the types are declared.
The types in STDLIB have been updated accordingly; for instance
-opaque dict() :: dict(_, _).
has been replaced by
-type dict() :: dict(_, _).

|
|
The parenthesized type with tag 'paren_type' is no longer created by
the Erlang Parser as of OTP 18.0.
The tag 'user_type' is used for user defined types as of OTP 18.0. In
releases before commit 7ad783 'type' is used.
|
|
|
|
|
|
Before OTP 18, parentheses are kept by the Erlang Parser, and
converted by EDoc ('paren_type' to #t_paren{}). As of OTP 18, the
parser no longer keeps parentheses, why EDoc needs to insert them when
converting Erlang types and specs to EDoc types and specs. As it
seems, it is only annotations that sometimes require parentheses.
|
|
Add new functions erl_parse:type_inop_prec() and
erl_parse:type_preop_prec().
Get rid of paren_type used for parentheses in types.

Add a check to protect from segfault when erlang:get_module_info/1/2 is
called on a deleted module (i.e. with no current code). Also refactor
erts_module_info_0/1 to avoid repeated calls to erts_active_code_ix() and
remove some obsolete comments. Add test for module_info on deleted modules.
