* rickard/scheduler-wait/OTP-9105: The emulator could get into a state where it didn't check for I/O.
2011-03-09Make halfword emulator with valgrind target allocate low memorySverker Eriksson
Limit ERTS_MSEG_FAKE_SEGMENTS (that is otherwise set for valgrind target) to not apply to low memory needed by halfword emulator. This will reduce the fault detection capability of valgrind for low memory. Also correct a bug in the initial mmap and make sure the returned memory region does not reach into high memory.

* sverker/clarify_nif_resource_doc: clarify NIF resource object deallocation documentation
2011-03-09clarify NIF resource object deallocation documentationSteve Vinoski
In the erl_nif documentation, clarify how and when NIF resource objects can be deallocated. Specifically, add focus for the case of calling enif_release_resource immediately after obtaining a resource term from enif_make_resource, since this is likely to be a common approach NIFs use to manage resources. Also fix a couple misspellings in the erl_nif documentation.
2011-03-09Fix 18 exabyte memory allocation failureBjörn Gustavsson
The new_binary() function takes a size argument that is an int. In the 64-bit emulator (sizeof(int) == 4, sizeof(Uint) == 8), any sizes >= 0x8000000 become 0xffffffff80000000 and above and triggers a memory allocation failure. Change the type of the size argument to Uint, and change any callers that cast the argument to an int. Correction-by: Jon Meredith

2011-03-04erts: Initialize register that may be referenced by garbage collectionBjörn Gustavsson
The call_fun() function in the BEAM emulator is supposed to to put the fun term in the x register following the actual arguments and environment for the fun. But if the fun is not loaded and a call to the error_handler:undefined_lambda/3 function is set up, the x(3) register will not be initialized. The lack of initialization is very unlikely to cause a problem in practice, because all of the following things must happen: 1) An unloaded fun must be called (i.e. the fun must have been received from another node or from a file or dets table). 2) The process must be scheduled out before the call to the error_handler:undefined_lambda/3 function can take place. 3) The process must be garbage collected before the process is scheduled in. 4) The x(3) register must contain a stale cons or box pointer that happens to point into the the heap of the currently executing process. (Because of the literal pool, the GC will never copy anything that is outside of the heap.) I was not able to write a test case that would force an emulator crash.
