2016-02-24erts: Change erl_exit into erts_exitSverker Eriksson
This is mostly a pure refactoring. Except for the buggy cases when calling erlang:halt() with a positive integer in the range -(INT_MIN+2) to -INT_MIN that got confused with ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT. Outcome OLD erl_exit(n, ) NEW erts_exit(n, ) ------- ------------------- ------------------------------------------- exit(Status) n = -Status <= 0 n = Status >= 0 crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0 The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and ERTS_DUMP_EXIT are the same as before (even though their values have changed).
2015-08-18Handle ERRNO_BLOCK in fd_driver async functionsSteve Vinoski
Several users on erlang-questions have reported problems with recent releases where output to standard_error causes standard_error_sup to die from receiving an unexpected eagain error. In the fd_driver, change the fd_async() function to handle EINTR, and change fd_ready_async() to handle ERRNO_BLOCK. Add a new test to standard_error_SUITE to generate output to standard_error and ensure that standard_error_sup does not die. Thanks to Kota Uenishi for contributing the test case.

2015-05-06erts: Increase buffer in erts_fp_check_init_errorMikael Pettersson
The current size is too small for 64-bit machines, causing messages to be truncated and making debugging more difficult.
2015-04-28erl_child_setup.c: fix Android breakageMikael Pettersson
The Android support in erl_child_setup.c is broken: 1. The close fd loop compares an fd (integer i) with the address of the function __system_properties_fd rather than the value of calling that function. 2. This function is locally defined, but its name starts with two underscores which is reserved for the implementation. 3. This function is not used outside of this file, so should be static. 4. This function performs a fair amount of work (calls getenv and atoi), which would be repeated for each and every fd in the [from,to] range. 5. This function contains an unsed local variable 's'. Fixed by dropping the __ prefix, making the function static, dropping the unused local variable, and rewriting the close fd loop to call the function at most once.

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.

This commit improves crash dumps in several ways: * Suspends schedulers to get a current snapshot * Dumps information about scheduler * Dumps stack trace of current running process (including Garbing processes)

These functions allow any thread to suspend any other thread immediately and then resume all threads. This is useful when doing a crash dump in order to get a more accurate picture of what state the system is in.

2014-11-24erts: Use finite instead of isfinite with gccLukas Larsson
Turns out that isfinite emits a function call and not an instruction in gcc, this makes estone float arith about 50-75% slower. finite emits the instruction so we use that instead.
