2016-02-23erts: Make literal_alloc documented and configurableSverker Eriksson
Except it cannot be disabled and cannot be multi-threaded. The bit-vector 'erts_literal_vspace_map' on 32-bit is currently only protected by the literal allocator mutex. We could allow multiple instances on 64-bit (I think), but what would be the point?

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.

2015-10-02Fix erroneous splitting of emulator pathMagnus Ottenklinger
`ct_run.c`, `erlc.c`, `escript.c` and `typer.c` do not preserve space characters in the emulator path. Thus, if a path containing space is passed via environment variables, such as `ESCRIPT_EMULATOR`, or if `get_default_emulator(progname)` returns a path with space, the execution of the programs fail. This patch fixes all occurrences found with `grep push_words -R $ERL_TOP`.

The OSE port is no longer supported and this commit removed it and any changes related to it. The things that were general improvements have been left in the code.

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.
