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.

2015-06-15erts: Remove hashmap probabilistic heap overestimationSverker Eriksson
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.

2015-06-15erts: Optimize maps:mergeSverker Eriksson
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.

2015-06-12Update the documentation of the abstract formatHans Bolinder
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.

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.

All flags was not always set when setting multiple aux work flags at once. This scenario is fortunately quite uncommon and only caused further delay in memory deallocations.
