* 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.

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.

Adding ERTS_SWORD_MAX to a pointer does not work
as a way to disable a bound check.
Remove the hp_end from ErtsHeapFactory as it isn't really used anyway.

Thanks to Michał Ptaszek for bringing this embarrassing formatting error to
my attention. Many DTrace/SystemTap trace strings are incorrectly
truncated at 4/8 bytes, depending on the CPU word size. This patch expands
the work from commit d032e097 by zheng siyao.

Functionality for scheduling operations at thread progress later
has been introduced.
Deallocation of ETS table structures were previously done by scheduling
misc aux work. Deallocation of process structures (not released yet)
was also implemented this way. Instead of using the misc aux work
functionality these implementation now use the newly introduced
functionality for scheduling operations at thread progress later. By
using this new functionaliy we reduce the amount of memory
allocation/deallocation operations needed.

dtrace doesn't print sender pid and receiver pid in message related
probe correctly, it truncates pid string to 7 characters on 64bit
platform(or 3 characters on 32bit platform). The dtrace related code
did not set the string length correctly, it sets the string length to
the length of a pointer rather than the buffer length.

The hybrid heap emulator was last working in the non-SMP R11B
run-time system. When the constant pools were introduced in R12B,
the hybrid heap emulator was not updated to handle them.
At this point, the harm from reduced readability of the code is
greater than any potential usefulness of keeping the code.

User tags in a dynamic trace enabled VM are spread throughout the system
in the same way as seq_trace tokens. This is used by the file module
and various other modules to get hold of the tag from the user process
without changing the protocol.

Add probes to the virtual machine, except (mostly) the efile_drv.c
driver and other file I/O-related source files.

Since refc binaries are now supported in literal pools, there is no
longer any need to allow the creation of over-sized heap binaries.
|
|
This will reduce the risk of integer wrapping in bin vheap counting.
The vheap size series will now use the golden ratio instead of doubling
and fibonacci sequences.

Merging the three off-heap lists (binaries, funs and externals) into
one list. This reduces memory consumption by two words (pointers) per
ETS object.

New NIF features:
Send messages from a NIF, or from thread created by NIF, to any local
process (enif_send)
Store terms between NIF calls (enif_alloc_env, enif_make_copy)
Create binary terms with user defined memory management
(enif_make_resource_binary)
|
|
fragments was created. This will mainly benefit NIFs that return
large compound terms.
