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.

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.

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.

The example of how to create a first target system, which is located in the System Principles document, is now extended to also include an example of code upgrade. A new chapter is added to System Principles explaining different issues when upgrade includes new versions applications within Erlang/OTP.

2014-03-28Add info about upgrade of core applicationsSiri Hansen
In ref man for appup and in system documentation, design prinsiples, add a warning related to upgrade when version of erts, kernel, stdlib or sasl is changed. This will cause an emulator restart where new version of emulator and core applications will startup together with old versions of other applications. Care must be taken to avoid problems due to backwards incompatibility.

* vinoski/sys-get-rep-state2: remove tuple funs from special process documentation fix sys:get_state/1,2 and sys:replace_state/2,3 when sys suspended OTP-11817
2014-03-21remove tuple funs from special process documentationSteve Vinoski
Support for tuple funs was removed in R16B but the documentation for special processes, sys, and proc_lib in the OTP Design Principles still showed examples using them, and those examples no longer worked. Fix the examples to use regular functions instead and fix the documentation to reflect the changes.
2014-03-21fix sys:get_state/1,2 and sys:replace_state/2,3 when sys suspendedSteve Vinoski
Add two new system callbacks Module:system_get_state/1 and Module:system_replace_state/2 to allow sys:get_state/1,2 and sys:replace_state/2,3 to operate correctly even if a process is sys suspended. Modify gen_server, gen_fsm, and gen_event to support the new callbacks. If a callback module does not export these functions, then by default the Misc value (the same as that passed as the final argument to sys:handle_system_msg/6, and returned as part of the return value of sys:get_status/1,2) is treated as the callback module's state. The previous behaviour of intercepting the system message and passing a tuple of size 2 as the last argument to sys:handle_system_msg/6 is no longer supported. Add tests to verify the correctness of sys:get_state/1,2 and sys:replace_state/2,3 when processes are sys suspended. Add two tests for modules that implement special processes, one that exports system_get_state/1 and system_replace_state/2 and one that doesn't. Much of the credit for this patch goes to James Fish, who reported the initial problem and implemented much of the fix.
