* sverk/halt-INT_MIN:
erts: Make erlang:halt() accept bignums as Status
erts: Change erl_exit into erts_exit
kernel: Remove calls to erl_exit

Just mask away the high bits to get a more tolerant erlang:halt
that behaves the same on 32 and 64 bit architectures.

A new {line_delimiter, byte()} option allows line-oriented TCP-based
protocols to use a custom line delimiting character. It is to be
used in conjunction with {packet, line}.
This option also works with erlang:decode_packet/3 when its first argument
is 'line'.

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.

This patch allows checking for NIF API version in a way similar to
driver version. E.g. by calling erlang:system_info(nif_version).

* bjorn/erts/export-bifs/OTP-12099:
BIFs should be considered exported
|
|
Specify in the documentation that erlang:statistics(runtime) returns milliseconds.
|
|
* etsukata/system_info_tolerant_timeofday/OTP-11970:
Add erlang:system_info(tolerant_timeofday)
|
|
All BIFs now have stub functions and are exported. For example
in the erlang module:
-export([..., is_list/1, ...]).
.
.
.
is_list(_Term) ->
erlang:nif_error(undefined).
But erlang:function_exported(erlang, is_list, 1) returns false,
which is weird.
Change erlang:function_exported/3 to return true for BIFs.
|
|
Add erlang:system_info(tolerant_timeofday), an API to check whether
compensation for sudden changes of system time is enabled or not.
