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.

2015-06-10Fix segfault in module_info for deleted modulesRichard Carlsson
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.

2015-05-27erts: Rename ErlNifMapIteratorEntry enumsSverker Eriksson
To differentiate between first/last map entry and head/tail which is before/after first/last map entry.
2015-05-26Add enif_raise_exceptionSteve Vinoski
Add enif_raise_exception function to allow NIFs to raise error exceptions holding any Erlang terms. This does not replace or deprecate the enif_make_badarg function, though, because raising badarg errors is so idiomatic in NIFs. Reimplement enif_make_badarg on top of enif_raise_exception. Add new tests for enif_raise_exception for both normal and dirty NIFs. Add documentation for enif_raise_exception.
2015-05-26Enhance enif_has_pending_exceptionSteve Vinoski
Sverker Eriksson came up with the following idea: to handle a future ability for NIFs to raise more than just badarg exceptions, modify the recently-added enif_has_pending_exception function to take a second argument: a pointer to ERL_NIF_TERM. If this argument is a null pointer, ignore it. Otherwise, if the first argument, an ErlNifEnv*, has an associated exception, set the pointed-to ERL_NIF_TERM of the second argument to the value of the exception term. Add new tests and documentation for this modification.
2015-05-26Fix for enif_schedule_nif and exceptionsSteve Vinoski
Fix a place where part of the implementation of enif_schedule_nif was not using the ErlNifEnv exception_thrown field when it should have been. Also make the result of enif_schedule_nif return false when passed to enif_is_exception, and add an assertion for this to the nif_SUITE.c tests.

2015-05-25erts: Fix garbage collect literals in code purgeBjörn-Egil Dahlberg
During code purging and check_process_code, the checking of the binary reference embedded in the match binary state was omitted for the tracing tests. This would cause the binary match state to reference deallocated memory.

2015-05-18Avoid timer wheel work in dirty schedulersSteve Vinoski
Dirty schedulers are limited in the type of work they can perform. Make sure they do not participate in any work or make any function calls related to timer wheels.
2015-05-12Correct usage of sizeof() for pointer typesJesper Louis Andersen
Given some pointer *x, calling sizeof(x) will give us the size of the pointer (4/8 bytes) not the size fo the underlying dereferenced structure. Use coccinelle to search for these occurrences in the source code, and correct them one by one. In the case of erl_node_tables.c, the erts_snprintf() calls used a much too small buffer. - run_erl.c: Use the size of the signal type, not its pointer. - erl_node_tables.c: Use the size of the _BUFFER in erts_snprintf() to make sure we can use the full space.
