2015-03-23Better support for poor os monotonic sourcesRickard Green
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.

2014-02-24ose: Add module that allows interaction with any OSE processLukas Larsson
The interface of this module is made to be as generic as possible in order for other IPC mechanisms to mimic it and allow porting of code between different os:es.
2014-02-24Added support for ENEA OSELukas Larsson
This port has support for both non-smp and smp. It contains a new way to do io checking in which erts_poll_wait receives the payload of the polled entity. This has implications for all linked-in drivers.

2013-11-01erts: Move compiler flags generationLukas Larsson
Move the call to utils/make_compiler_flags to after _create_dirs to make sure that the dirs are created before we try to generate files in there. This seems to work with parallel make as well, but I cannot find any documentation that says that it should or should not work.

2013-05-28Fix receive support in erl_eval with a BEAM moduleAnthony Ramine
Using the low-level BEAM instructions, we can loop over each message in the process queue and removes the first message that matches, without receiving them all to later send them back to itself. The function prim_eval:'receive'/2 is equivalent to the following pseudo-code: 'receive'(F, T) -> RESET MESSAGE QUEUE POINTER, LOOP: case PEEK CURRENT MESSAGE WITH TIMEOUT T of {ok,Msg} -> case F(Msg) of nomatch -> DECREMENT TIMEOUT T, ADVANCE MESSAGE QUEUE POINTER, GOTO LOOP; Result -> RESET MESSAGE QUEUE POINTER, Result end; timeout -> RESET MESSAGE QUEUE POINTER, timeout end. To not break Dialyzer and other tools, we use a stub Erlang module which abstract code is forcefully inserted into prim_inet.erl afterwards compilation.

2013-02-13Include git sha in prompt if availableLukas Larsson
The sha will only be included if there is no tag starting with OTP_R* associated with the sha. This is because we do not want the sha to show on offical releases.
2013-01-15Implement ./otp_build configure --enable-silent-rulesAnthony Ramine
With silent rules, the output of make is less verbose and compilation warnings are easier to spot. Silent rules are disabled by default and can be disabled or enabled at will by make V=0 and make V=1.
