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.

2015-05-12erts: Fix erts_send_error_term_to_logger memory leakBjörn-Egil Dahlberg
2015-05-11Send format and args on process exit to error_loggerJosé Valim
Previously, the emulator would generate a whole string with values and call the error_logger passing "~s~n". This commit changes it to a format string containing ~p with the respective values as arguments.
2015-05-11Add erts_send_error_term_to_loggerJosé Valim
This function allows us to send format and args to the logger which can then be formatted and customized from Erlang land.

sys_write_buf allocator type is used from async-threads and needs to be lockable. In the SMP case the temporary allocator is lockable but not in the Non-SMP case. To remedy this the binary-allocator is used for the Non-SMP case, which is lockable.
