This document describes the changes made to the ERTS application.

+
Erts 7.0.2 + +
Fixed Bugs and Malfunctions + + +

+ A process could end up in an inconsistent half exited + state in the runtime system without SMP support. This + could occur if the processes was traced by a port that it + also was linked to, and the port terminated abnormally + while handling a trace message for the process.

+

+ This bug has always existed in the runtime system without + SMP support, but never in the runtime system with SMP + support.

+
+ +

+ Removed unnecessary copying of data when retrieving + corrected Erlang monotonic time.

+

+ Own Id: OTP-12894

+
+ +

+ Changed default OS monotonic clock source chosen at build + time. This in order to improve performance. The behavior + will now on most systems be that (both OS and Erlang) + monotonic time stops when the system is suspended.

+

+ If you prefer that monotonic time elapse during suspend + of the machine, you can pass the command line argument + --enable-prefer-elapsed-monotonic-time-during-suspend + to configure when building Erlang/OTP. The + configuration stage will try to find such a clock source, + but might not be able to find it. Note that there might + be a performance penalty associated with such a clock + source.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+
+ +

+ erlang:system_info(end_time) returned a faulty + value on 32-bit architectures.

+ + +
Improvements and New Features + + +

+ The configure command line argument + --enable-gettimeofday-as-os-system-time has been + added which force usage of gettimeofday() for OS + system time. This will improve performance of + os:system_time() and os:timestamp() on + MacOS X, at the expense of worse accuracy, resolution and + precision of Erlang monotonic time, Erlang system time, + and OS system time.
