2015-12-08Replace off_heap_message_queue option with message_queue_data optionRickard Green

* rickard/ohmq/OTP-13047: Fragmented young heap generation and off_heap_message_queue option Refactor GC Introduce literal tag Conflicts: erts/doc/src/erlang.xml erts/emulator/beam/erl_gc.c
2015-11-12Fragmented young heap generation and off_heap_message_queue optionRickard Green
* The youngest generation of the heap can now consist of multiple blocks. Heap fragments and message fragments are added to the youngest generation when needed without triggering a GC. After a GC the youngest generation is contained in one single block. * The off_heap_message_queue process flag has been added. When enabled all message data in the queue is kept off heap. When a message is selected from the queue, the message fragment (or heap fragment) containing the actual message is attached to the youngest generation. Messages stored off heap is not part of GC.

A new {line_delimiter, byte()} option allows line-oriented TCP-based protocols to use a custom line delimiting character. It is to be used in conjunction with {packet, line}. This option also works with erlang:decode_packet/3 when its first argument is 'line'.

2015-03-20Introduce a new time APIRickard Green
The old time API is based on erlang:now/0. The major issue with erlang:now/0 is that it was intended to be used for so many unrelated things. This tied these unrelated operations together and unnecessarily caused performance, scalability as well as accuracy, and precision issues for operations that do not need to have such issues. The new API spreads different functionality over multiple functions in order to improve on this. The new API consists of a number of new BIFs: - erlang:convert_time_unit/3 - erlang:monotonic_time/0 - erlang:monotonic_time/1 - erlang:system_time/0 - erlang:system_time/1 - erlang:time_offset/0 - erlang:time_offset/1 - erlang:timestamp/0 - erlang:unique_integer/0 - erlang:unique_integer/1 - os:system_time/0 - os:system_time/1 and a number of extensions of existing BIFs: - erlang:monitor(time_offset, clock_service) - erlang:system_flag(time_offset, finalize) - erlang:system_info(os_monotonic_time_source) - erlang:system_info(time_offset) - erlang:system_info(time_warp_mode) - erlang:system_info(time_correction) - erlang:system_info(start_time) See the "Time and Time Correction in Erlang" chapter of the ERTS User's Guide for more information.

* etsukata/system_info_tolerant_timeofday/OTP-11970: Add erlang:system_info(tolerant_timeofday)
2014-05-12BIFs should be considered exportedBjörn Gustavsson
All BIFs now have stub functions and are exported. For example in the erlang module: -export([..., is_list/1, ...]). . . . is_list(_Term) -> erlang:nif_error(undefined). But erlang:function_exported(erlang, is_list, 1) returns false, which is weird. Change erlang:function_exported/3 to return true for BIFs.

Add erlang:system_info(tolerant_timeofday), an API to check whether compensation for sudden changes of system time is enabled or not.
