2015-06-15erts: Remove hashmap probabilistic heap overestimationSverker Eriksson
by adding a dynamic heap factory. "binary_to_term" is now a hybrid solution with both a call to decoded_size() to calculate needed heap space AND possible dynamic allocation of more heap space if needed for big maps. The heap size returned from decoded_size() is guaranteed to be sufficient for all term heap data except for hashmap nodes. All hashmap nodes are created at the end of dec_term() by invoking the heap factory interface that may allocate more heap space on process heap or in fragments. With this commit it is no longer guaranteed that a message is confined to only one heap fragment.

A faulty "box-value" entered into the heap which could cause a segmentation fault in the garbage collector if it was written on a heap fragment.

* rickard/thr-progress-block/OTP-9631: Replace system block with thread progress block
2011-11-13Replace system block with thread progress blockRickard Green
The ERTS internal system block functionality has been replaced by new functionality for blocking the system. The old system block functionality had contention issues and complexity issues. The new functionality piggy-backs on thread progress tracking functionality needed by newly introduced lock-free synchronization in the runtime system. When the functionality for blocking the system isn't used there is more or less no overhead at all. This since the functionality for tracking thread progress is there and needed anyway.

2011-10-26Change the calling convention for BIFsBjörn Gustavsson
The current calling convention for BIFs makes it necessary to handle each arity specially, since each argument for the BIF also becomes an argument for the C function implementing the BIF, which makes it hard to allow BIFs with any number of arguments. Change the calling convention for BIFs, so that BIF arguments are passed in an array to the C function implementing the BIF.
2011-10-26Use the proper macros in all BIFsBjörn Gustavsson
As a preparation for changing the calling convention for BIFs, make sure that all BIFs use the macros. Also, eliminate all calls from one BIF to another, since that also breaks the calling convention abstraction.

2011-07-07Fix a match-spec trace bug that could cause emulator crashSverker Eriksson
A trace matchspec with 'enable_trace' or 'disable_trace' in body could cause an emulator crash if a concurrent process altered the trace setting of the traced function by calling erlang:trace_pattern. The effect was a deallocation of the binary holding the matchspec program while it was running. Fixed by increasing reference count of ms-binary in the cases when 'enable_trace' or 'disable_trace' may cause a system block that may alter the ongoing trace. The paradox here is that db_prog_match() is using erts_smp_block_system() to do 'enable_trace' and 'disable_trace' in a safe (atomic) way. But that also have the (non-atomic) effect that racing thread might block the system and change the trace settings with erlang:trace_pattern.
2011-06-14Use new atomic API in runtime systemRickard Green
All uses of the old deprecated atomic API in the runtime system have been replaced with the use of the new atomic API. In a lot of places this change imply a relaxation of memory barriers used.
2011-03-16erts_printf %be to print integers of size EtermSverker Eriksson
Existing %bp to print pointer size integers does not work in halfword emulator to print Eterm size integers.
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
