* sverk/term2bin-simplify: erts: Refactor ESTACK & WSTACK to use a struct easy to "export" erts: Fix benign ESTACK/WSTACK typo erts: Fix compiler warnings for NO_JUMP_TABLE erts: Run binary_SUITE:trapping even for 32bit erts: Extend binary_SUITE:ttb_trap to also cover binary_to_term erts: Remove the extra_root feature from the process structure erts: Simplify term_to_binary by removing saved ESTACK from root set
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.

2013-11-18Functionality 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.

2013-06-05Make all steps ofterm_to_binary work in chunks and yieldPatrik Nyblom
Rewrite and extend of Happi's initial work Extra_root to process structure to enable GC of state - Changed the process structure to point to a separate struct, the struct also contains a destructor function to allow for proper cleanup. Rewrote encode_size_struct and enc_term to have internal versions with reduction counters which will result in interrupt for later restart when the counter reaches zero - removed the EWA_STACK from Happis version and directly save the ESTACK's and WSTACK's in the above mentioned struct (or array thereof) that are pointed out from the process structure. The destructor will take care of the deallocation in case of process death. Added ESTACK and WSTACK macros to save and restore stack and to change allocator, which makes the previously mentioned stack-save work. Rewrote enc_term to not store pointers on the stack, and use one WSTACK for commands etc and another ESTACK for Eterms - Slightly different than Happis version to make halfword code simpler. Rewrote encode_size_struct2 so that it does not store pointers on the stack, also switched to ESTACK instead of WSTACK, this also handles halfword correctly. Added interfaces for chunkwise compression, that are used from term_to_binary/2 when the compressed option is given.
