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.
2015-11-10erts: Fix bug in setnode/2Sverker Eriksson
that could lead strange things to happen when renaming a node with a name that already exist in node and dist tables. Problem: erts_set_this_node() is a bit brutal and does not handle the case when an old remote node name is reused as the new local node name. Solution: Treat erts_this_node and erts_this_dist_entry as all the others with correct reference counting.
2015-11-02erts: Remove ERTS_PSD_DIST_ENTRYSverker Eriksson
Not needed as it is always set to erts_this_dist_entry (on net_kernel).

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.

2015-03-30erts: Refactor encode_size_struct_intSverker Eriksson
to handle the "start of list" case in one place and not seven. Note that this commit reverts (47d6fd3ccf35) back to using WSTACK and pushing raw pointers. We disable GC while yielding, so this should not be a problem.

except the reference counter 'refc', as different callers have different strategies regarding the lifetime of the binary.
2014-08-29erts: Implement yielding for distributed send of large messagesSverker Eriksson
Use same mechanism as term_to_binary to yield while encoding large messages for distributed send.
2014-03-12Pass full strings to DTrace probesMichal Ptaszek
Whenever string is passed as an argument to a DTrace probe, its length should be properly computed. Until now in order to get length of the input buffer size_of(char *) was used - which evalutes to 4 or 8 (depending on the architecture). To get a proper length, size_of(DTRACE_CHARBUF_NAME(buffer_name)) should be used.

2013-05-16Change rwlock to rlock where possibleLukas Larsson
Having rwlock could cause high unneccesary contention on the dist table when calling erlang:nodes() from many schedulers at the same time.

2012-08-14Make get/putenv and erlexec understand UnicodePatrik Nyblom
Putenv and getenv needs to convert to the proper environment strings in Unicode depending on platform and user settings for filename encoding. Also erlexec needs to pass environment strings in an appropriate way for kernel to pick up. All environment strings on the command line, as well as home directory, is now passed in UTF8 on windows and in whatever encoding you have on Unix, kernel tries to convert all parameters and environments from UTF8 before making strings.

2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
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.
