* egil/18/fix-maps-binary_to_term/OTP-13125: erts: More testcases for map binary_to_term/1 erts: Fix maps decode in erlang:binary_to_term/1
2015-11-20erts: Fix maps decode in erlang:binary_to_term/1Björn-Egil Dahlberg
Decoding a term with a large (HAMT) map in an small (FLAT) map could cause a critical error if the external format was not produced by beam.
2015-11-19Refactor have seq_trace token testBjörn-Egil Dahlberg
2015-11-18Use sharing preserving copy error messages and exceptionsBjörn-Egil Dahlberg
2015-11-18Use sharing preserving copy in enif_make_copyBjörn-Egil Dahlberg
2015-11-18Refactor sharing preserved copy flagsBjörn-Egil Dahlberg
The TMPBUF option is no longer needed due to is_literal test and NONE was only used for initial debugging. So we remove the entire option.

2015-11-17Fix Map preserved sharing copy implementationBjörn-Egil Dahlberg
The Map implementation has changed since initial preserved copy implementation.
2015-11-17Fix Halfword removalBjörn-Egil Dahlberg
Halfword is no longer present in the runtime system.
2015-11-17Fix internal stacksBjörn-Egil Dahlberg
The internal stacks has changed between releases.
2015-11-17Add support for maps in preserved copyNikolaos S. Papaspyrou
2015-11-17Add --enable-sharing-preserving configure flagYiannis Tsiouris
2015-11-17Add -debug +vc flag for debuging SHCOPYNikolaos S. Papaspyrou
This is very verbose, you have been warned. It should work with the copy-spy.py script, which may be a bit outdated.
2015-11-17Enable shcopy for spawning processesNikolaos S. Papaspyrou
2015-11-17Add machinery to enable SHCOPY dynamicallyNikolaos S. Papaspyrou
This commit is just for debugging purposes, will probably be reverted. It comes with a the erts_debug:copy_shared/1 BIF. If SHCOPY_DISABLE is defined, SHCOPY starts disabled and is dynamically enabled the first time that the BIF is called.
2015-11-17Remove DTrace Harddebug clutterBjörn-Egil Dahlberg
2015-11-17Enable shcopy for sending messagesNikolaos S. Papaspyrou
2015-11-17Add the BIF size_shared/1 and debug cleanupNikolaos S. Papaspyrou
2015-11-17Add all the main machineryNikolaos S. Papaspyrou
Add functions size_shared, copy_shared_calculate and copy_shared_perform. Add the infrastructure for making these communicate with each other. Add debug information to other places in the VM, to watch interaction with the sharing-preserving copy. CAUTION: If you define the SHCOPY_DEBUG macro (after SHCOPY is actually used in the VM) and make the whole OTP, there will be a lot of debugging messages during make (it will also be enabled in erlc). You have been warned...

2015-11-12Improve yield strategy for list_to_binary()/binary_to_list()Rickard Green
Avoid yield in the BIF when input is small. This either yielding before beginning to work in the BIF, or by allowing some more reductions before yielding.

2015-11-12Fragmented young heap generation and off_heap_message_queue optionRickard Green
* The youngest generation of the heap can now consist of multiple blocks. Heap fragments and message fragments are added to the youngest generation when needed without triggering a GC. After a GC the youngest generation is contained in one single block. * The off_heap_message_queue process flag has been added. When enabled all message data in the queue is kept off heap. When a message is selected from the queue, the message fragment (or heap fragment) containing the actual message is attached to the youngest generation. Messages stored off heap is not part of GC.
