2013-11-18Parallel check_process_code when code_server purge a moduleRickard Green
When the code_server is about to purge a module it will now issue asynchronous check_process_code requests to all processes at once instead of one at a time. These check_process_code operation can execute in parallel.
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.

2013-09-19Teach erlc to handle UTF-8 file namesBjörn Gustavsson
The 'erlc' program passes options to the 'erl' program using the '-s' option. The '-s' option causes all options to be converted to atoms, which implies that UTF-8 file names may not be given on the command line. We could solve just the UTF-8 problem by using '-run' and change the erl_compile module to expect strings instead of atoms, but since that is an incompatible change, we should take the opportunity to make more incompatible changes while we are at it. Specifically, when 'erlc' was first written, there was no way to pass command line arguments starting with '-' to Erlang, so 'erlc' did all parsing of arguments and translated options to atoms starting with a '@' character (for example, -I was translated to @i). Since then, the '-extra' option has been introduced which allows us to pass anything to Erlang at the end of the command line. Therefore, while at it, do the minimum of necessary command line parsing in the 'erlc' program (e.g. the '-smp' option), passing the command line essentially unchanged to 'erl' using the '-extra' option, and rewrite the option parsing in Erlang.
