2015-03-20otp_SUITE: Warn for calls to erlang:now/0Björn Gustavsson
2015-03-20Multiple timer wheelsRickard Green
2015-03-20Erlang based BIF timer implementation for scalabilityRickard Green
2015-03-20Implement ethread events with timeoutRickard 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.
2014-12-10Use the new 64-bit atomic ops APIRickard Green
2014-12-10Introduce a 64-bit atomic ops APIRickard Green
The 64-bit atomic ops API is implemented by * native word size atomic ops on 64-bit architectures, and * native double word size atomic ops on 32-bit architectures when available. When native double word size atomic is not available, the fallback using modification counters is used.

clang aka llvm claims to be __GNUC__ and thus we have to explicitly check that it is not used.

2014-11-26Clean up temporary dtrace file during configSteve Vinoski
When configuring erts to support dynamic trace via dtrace, be sure to clean up the temporary file "erts/foo-dtrace.h" used to help check for dtrace support. Otherwise, it shows up as an untracked file in git.
2014-11-26Sort keys before generatingLukas Larsson
This has to be done in order to consistently generate the same file so that we do not get rebuilds all the time.

2014-11-24erts: Use finite instead of isfinite with gccLukas Larsson
Turns out that isfinite emits a function call and not an instruction in gcc, this makes estone float arith about 50-75% slower. finite emits the instruction so we use that instead.

There was once a plan to implement support for unicode atoms in OTP 18. This plan has been stopped until further notice, and the information about this is now removed from the documentation.
