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.

that could invalidate a pointer received from an earlier call to enif_inspect_binary. Solution: Emasculate writable binary at enif_inspect_binary. There are room for optimizations here as we now do an unconditional emasculation even though enif_make_copy is not called later in the NIF.

2011-01-18Lower the maximum arity from 256 to 255Björn Gustavsson
Historically, for no good reason, a function is allowed to have from 0 to 256 arguments. Thus, the number of arguments *almost* fits into a byte. HiPE only supports up to 255 arguments (because it assumes that the function arity fits into a single byte), and fixing that limitation would require ugly special-case handling. In Dialyzer, the arity type is defined to be a byte (i.e. 0..255). Since no-one uses functions with 256 arguments anyway, lower the limit to 255.
