2013-11-18erts: Add erlang wrappers to binary_to_termSverker Eriksson
to not expose the trapping BIF in the stacktrace when it throws badarg.
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.

2012-02-21Break apart erlang:load_module/2 into two separate BIFsBjörn Gustavsson
Introduce two new BIFs, erlang:prepare_loading/2 and erlang:finish_loading/1, and re-implement erlang:load_module/2 in Erlang code. We have two reasons for doing this: * To facilitate suspending a process if another process is already doing code loading. * In the future, we can implement parallel and atomic loading of several modules. Atomic loading works except for modules with on_load handlers. Because of that issue, erlang:finish_loading/2 will currently only accept a list with a single magic binary.

This involves exception BIF's, guar BIF's and some other complicated BIF's Also some minor corrections to documentation and specs in erlang.erl Added comment for each spec in erlang.erl shadowed by erl_bif_types. Dialyzer test should now run well except for one or two cases.

2011-11-30erlang: Eliminate a clause in aa_mem_data/2 that can never matchBjörn Gustavsson
aa_mem_data/2 is only called by aa_mem_data/1 and itself. aa_mem_data/1 called with the argument 'notsup' will never call aa_mem_data/2. aa_mem_data/2 will only call itself with a #memory{} record as the first argument. QED. Noticed-by: Dialyzer.
