2018-05-08erts: Make atomic ets:delete_all_objects yieldSverker Eriksson
by using a cooperative strategy that will make any process accessing the table execute delelete_all_objects_continue until the table is empty. This is not an optimal solution as concurrent threads will still block on the table lock, but at least thread progress is made.

2018-03-21Implementation of true asynchronous signaling between processesRickard Green
Communication between Erlang processes has conceptually always been performed through asynchronous signaling. The runtime system implementation has however previously preformed most operation synchronously. In a system with only one true thread of execution, this is not problematic (often the opposite). In a system with multiple threads of execution (as current runtime system implementation with SMP support) it becomes problematic. This since it often involves locking of structures when updating them which in turn cause resource contention. Utilizing true asynchronous communication often avoids these resource contention issues. The case that triggered this change was contention on the link lock due to frequent updates of the monitor trees during communication with a frequently used server. The signal order delivery guarantees of the language makes it hard to change the implementation of only some signals to use true asynchronous signaling. Therefore the implementations of (almost) all signals have been changed. Currently the following signals have been implemented as true asynchronous signals: - Message signals - Exit signals - Monitor signals - Demonitor signals - Monitor triggered signals (DOWN, CHANGE, etc) - Link signals - Unlink signals - Group leader signals All of the above already defined as asynchronous signals in the language. The implementation of messages signals was quite asynchronous to begin with, but had quite strict delivery constraints due to the ordering guarantees of signals between a pair of processes. The previously used message queue partitioned into two halves has been replaced by a more general signal queue partitioned into three parts that service all kinds of signals. More details regarding the signal queue can be found in comments in the erl_proc_sig_queue.h file. The monitor and link implementations have also been completely replaced in order to fit the new asynchronous signaling implementation as good as possible. More details regarding the new monitor and link implementations can be found in the erl_monitor_link.h file.

2018-02-26Replace binary:bin_to_list CIF implementation with binary_to_listJohn Högberg
binary:bin_to_list had a poor implementation that resulted in excessive garbage collection. binary_to_list is almost identical and has a generally better implementation, so I've replaced binary:bin_to_list's CIF with a thin wrapper around binary_to_list. Granted, binary_to_list has a deprecated indexing scheme, but we're unlikely to ever remote it entirely and it's somewhat easy to move it to the 'binary' module later on.

2017-11-20stdlib: Make io_lib and io_lib_pretty use maps iteratorLukas Larsson
2017-11-20erts: Implement batching maps:iteratorLukas Larsson
This iterator implementation fetches multiple elements to iterate over in one call to erts_internal:maps_next instead of one at a time. This means that the memory usage will go up for the iterator as we are buffering elements, but the usage is still bounded. In this implementation the max memory usage is 1000 words. Using this approach makes the iterator as fast as using maps:to_list, so maps:iterator/2 has been removed.
