2015-03-20Erlang based BIF timer implementation for scalabilityRickard Green
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.

The intention of this callback is to close all sockets associated to a port. It is closed only on crashdumps. This will currently only be used for the epmd port.

2014-01-17erts: Refactor ESTACK & WSTACK to use a struct easy to "export"Sverker Eriksson
This is not a clean refactor. It changes the behaviour slightly of E/WSTACK_RESTORE. The allocated stack from E/WSTACK_SAVE is used as-is and not copied into default_stack. This will hopefully fix an illusive memory leak that valgrind is reporting.

2013-12-07Merge branch 'rickard/garbage_collect/OTP-11388'Rickard Green
* rickard/garbage_collect/OTP-11388: Parallel check_process_code when code_server purge a module Functionality for disabling garbage collection Use asynchronous check_process_code in code_parallel_SUITE Execution of system tasks in context of another process Conflicts: bootstrap/lib/kernel/ebin/hipe_unified_loader.beam erts/preloaded/ebin/erlang.beam erts/preloaded/ebin/erts_internal.beam
2013-11-18Functionality for disabling garbage collectionRickard Green
Being able to disable garbage collection over context switches vastly simplifies implementation of yielding native code that builds large or complex data structures on the heap. This since the heap can be left in an inconsistent state over the context switch.
2013-11-18Execution of system tasks in context of another processRickard Green
A process requesting a system task to be executed in the context of another process will be notified by a message when the task has executed. This message will be on the form: {RequestType, RequestId, Pid, Result}. A process requesting a system task to be executed can set priority on the system task. The requester typically set the same priority on the task as its own process priority, and by this avoiding priority inversion. A request for execution of a system task is made by calling the statically linked in NIF erts_internal:request_system_task(Pid, Prio, Request). This is an undocumented ERTS internal function that should remain so. It should *only* be called from BIF implementations. Currently defined system tasks are: * garbage_collect * check_process_code Further system tasks can and will be implemented in the future. The erlang:garbage_collect/[1,2] and erlang:check_process_code/[2,3] BIFs are now implemented using system tasks. Both the 'garbage_collect' and the 'check_process_code' operations perform or may perform garbage_collections. By doing these via the system task functionality all garbage collect operations in the system will be performed solely in the context of the process being garbage collected. This makes it possible to later implement functionality for disabling garbage collection of a process over context switches. Newly introduced BIFs: * erlang:garbage_collect/2 - The new second argument is an option list. Introduced option: * {async, RequestId} - making it possible for users to issue asynchronous garbage collect requests. * erlang:check_process_code/3 - The new third argument is an option list. Introduced options: * {async, RequestId} - making it possible for users to issue asynchronous check process code requests. * {allow_gc, boolean()} - making it possible to issue requests that aren't allowed to garbage collect (operation will abort if gc should be needed). These options have been introduced as a preparation for parallelization of check_process_code operations when the code_server is about to purge a module.
