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.

* paulgray/dtrace_snprintf_fix/OTP-11816: Fix DTrace/SystemTap-related formatting
2014-03-25Fix DTrace/SystemTap-related formattingScott Lystig Fritchie
Thanks to Michał Ptaszek for bringing this embarrassing formatting error to my attention. Many DTrace/SystemTap trace strings are incorrectly truncated at 4/8 bytes, depending on the CPU word size. This patch expands the work from commit d032e097 by zheng siyao. Michał's report to the erlang-bugs list can be found at: http://erlang.org/pipermail/erlang-bugs/2014-March/004250.html Conflicts: erts/emulator/beam/beam_emu.c erts/emulator/beam/copy.c erts/emulator/beam/dist.c erts/emulator/beam/erl_async.c erts/emulator/beam/erl_bif_port.c erts/emulator/beam/erl_port_task.c erts/emulator/beam/erl_process.c erts/emulator/beam/io.c

* paulgray/dtrace_snprintf_fix/OTP-11816: Pass full strings to DTrace probes
2014-03-12Pass full strings to DTrace probesMichal Ptaszek
Whenever string is passed as an argument to a DTrace probe, its length should be properly computed. Until now in order to get length of the input buffer size_of(char *) was used - which evalutes to 4 or 8 (depending on the architecture). To get a proper length, size_of(DTRACE_CHARBUF_NAME(buffer_name)) should be used.
2014-02-24ose: Rewrite resolve_signal API for ose driversLukas Larsson
This new API has less impact on the check_io code and also removes the callback from ErlDrvEntry. The downside is that you have to give the resolve function when creating each event. Also the mode if the resolve was removed as this mimics the win32 code and decreases complexity.
2014-02-24ose,erts: Specify name for tsd keysLukas Larsson
This simplified debugging on OSE and also limits the number of ppdata keys that are created when beam is restarted.

2014-02-24Added support for ENEA OSELukas Larsson
This port has support for both non-smp and smp. It contains a new way to do io checking in which erts_poll_wait receives the payload of the polled entity. This has implications for all linked-in drivers.
2014-01-29erts: Add map construction to driver APISverker Eriksson
erl_drv_output_term() and erl_drv_send_term() can send messages containing maps with the use of the new ERL_DRV_MAP. The driver API minor version is updated as new functionality is added.
