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.
2014-12-19erts: Improve crash dumpsLukas Larsson
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)

When reaping ports the flushReplyEvent is not signalled and therefore an errornous loop check caused the emulator to hang forever during shutdown.

This is needed because a file has to be opened and operated on in the same process at all times. Using async threads guarantee this.

2014-01-15remove deprecated driver_async_cancel functionSteve Vinoski
Some time ago the driver_async_cancel function was deprecated and slated for removal in R17. This commit removes the function along with its associated tests and documentation, sets the ERL_DRV_EXTENDED_MAJOR_VERSION to 3 and ERL_DRV_EXTENDED_MINOR_VERSION to 0, and modifies the sys_info_base_drv and sys_info_prev_drv tests in the driver test suite to check version 3.0 instead of 2.0.

New BIF os:unsetenv/1 which deletes an environment variable and returns 'true'. Does not change any old functionality. Calls the libc function unsetenv(3) on UNIX and SetEnvironmentVariableW(key, NULL) on Windows. The unicode support is the same as for os:getenv and os:putenv.

2013-09-25Implement platform specific aligned sys_alloc and use when supportedRickard Green
erts_sys_aligned_alloc() is currently implemented using posix_memalign if it exist, or using _aligned_malloc on Windows. If erts_sys_aligned_alloc() exist allocators will create sys_alloc carriers similar to how this was done pre-R16.

config.h defines HAVE_SYSLOG_H whereas the sources are looking for NO_SYSLOG to be undefined. As the logic of "if feature is available" makes more sense than "if feature is not unavailable", I opted for the config.h define.

2013-08-23Create better distribution of files over async threadsPatrik Nyblom
The actual port id is used to create a key from the pointer value which is the ErlDrvPort. To do this a new driver api function driver_async_port_key is added and the driver API minor version is updated. The documentation is updated and the faulty description of how to spread ports over async threads is updated to use the new API. Testcase also added.
