2014-09-10erts: Correct dirty scheduler NIF API for WindowsSverker Eriksson
enif_schedule_nif() put LAST of the unconditional functions to keep the order which is vital for ABI compatibility on Windows. The conditional dirty scheduler stuff moved down at the end of the list to keep them out of the way. We don't want them mess things up then they become unconditional some day.

that could invalidate a pointer received from an earlier call to enif_inspect_binary. Solution: Emasculate writable binary at enif_inspect_binary. There are room for optimizations here as we now do an unconditional emasculation even though enif_make_copy is not called later in the NIF.

* vinoski/enif-schedule-nif: add enif_schedule_nif() to NIF API
2014-08-28add enif_schedule_nif() to NIF APISteve Vinoski
In the #erlang IRC channel Anthony Ramine once mentioned the idea of allowing a NIF to use an emulator trap, similar to a BIF trap, to schedule another NIF for execution. This is exactly how dirty NIFs were implemented for Erlang/OTP 17.0, so this commit refactors and generalizes that dirty NIF code to support a new enif_schedule_nif() API function. The enif_schedule_nif() function allows a long-running NIF to be broken into separate NIF invocations. The NIF first executes part of the long-running task, then calls enif_schedule_nif() to schedule a NIF for later execution to continue the task. Any number of NIFs can be scheduled in this manner, one after another. Since the emulator regains control between invocations, this helps avoid problems caused by native code tying up scheduler threads for too long. The enif_schedule_nif() function also replaces the original experimental dirty NIF API. The function takes a flags parameter that a caller can use to indicate the NIF should be scheduled onto either a dirty CPU scheduler thread, a dirty I/O scheduler thread, or scheduled as a regular NIF on a regular scheduler thread. With this change, the original experimental enif_schedule_dirty_nif(), enif_schedule_dirty_nif_finalizer() and enif_dirty_nif_finalizer() API functions are no longer needed and have been removed. Explicit scheduling of a dirty NIF finalization function is no longer necessary; if an application wants similar functionality, it can have a dirty NIF just invoke enif_schedule_nif() to schedule a non-dirty NIF to complete its task. Lift the restriction that dirty NIFs can't call enif_make_badarg() to raise an exception. This was a problem with the original dirty NIF API because it forced developers to get and check all incoming arguments in a regular NIF, and then schedule the dirty NIF which then had to get all the arguments again. Now, the argument checking can be done in the dirty NIF and it can call enif_make_badarg() itself to flag incorrect arguments. Extend the ErlNifFunc struct with a new flags field that allows NIFs to be declared as dirty. The default value for this field is 0, indicating a regular NIF, so it's backwards compatible with all existing statically initialized ErlNifFunc struct instances, and so such instances require no code changes. Defining the flags field with a value of ERL_NIF_DIRTY_JOB_CPU_BOUND indicates that the NIF should execute on a dirty CPU scheduler thread, or defining it with a value of ERL_NIF_DIRTY_JOB_IO_BOUND indicates that the NIF should execute on a dirty I/O scheduler thread. Any other flags field value causes a NIF library loading error. Extend the ErlNifEntry struct with a new options field that indicates whether a NIF library was built with support for optional features such as dirty NIFs. When a NIF library is loaded, the runtime checks the options field to ensure compatibility. If a NIF library built with dirty NIF support is loaded into a runtime that does not support dirty NIFs, and the library defines one or more ErlNifFunc entries with non-zero flags fields indicating dirty NIFs, a NIF library loading error results. There is no error if a NIF library built with dirty NIF support is loaded into a runtime that does not support dirty NIFs but the library does not have any dirty NIFs. It is also not an error if a library without dirty NIF support is loaded into a runtime built with dirty NIF support. Add documentation and tests for enif_schedule_nif().

2014-08-08erts: Fix neg int overflow when sint is min sizeLukas Larsson
When INT64_MIN is the value of a Sint64 we have to first cast it to an Uint64 before negating it. Otherwise we get an integer overflow which is undefined behaviour and in gcc 4.9 this results in -0 instead of -9223372036854775808 in gcc 4.8.

2014-08-07Fix emigrate bug in erts_port_task_schedule()Rickard Green
While current run-queue lock is unlocked in the call to erts_check_emigration_need() from erts_port_task_schedule() the port can be migrated to another run-queue by another thread. The code in erts_port_task_schedule() needs to check if this has occurred when returning from erts_check_emigration_need(), and if so respect the migration decision. When this was not done, the thread calling erts_port_task_schedule() held the wrong run-queue lock which caused invalid updates of the port task queue. This bug was automatically fixed by the rewrites in the branch rickard/r16b/port-optimizations-fixes/OTP-10336 (commit 56cef897ca3ad2377e34a6ea5800a54a28cbeb6e) introduced in erts-5.10 and do not effect erts versions after that.
