2015-12-08Distinguish between GC disabled by BIFs and other disabled GCRickard Green
Processes remember heap fragments that are known to be fully live due to creation in a just called BIF that yields in the live_hf_end field. This field must not be used if we have not disabled GC in a BIF. F_DELAY_GC has been introduced in order to distinguish between to two different scenarios. - F_DISABLE_GC should *only* be used by BIFs. This when the BIF needs to yield while preventig a GC. - F_DELAY_GC should only be used when GC is temporarily disabled while the process is scheduled. A process must not be scheduled out while F_DELAY_GC is set.

2015-12-03erts: Fix bug in heap_factory_undo for FACTORY_HEAP_FRAGS modeSverker Eriksson
Make sure a heap fragment is not deallocated before all off_heap terms have been cleared. The fix assumes/asserts that the off_heap-lists of all additional heap fragments are empty. I think this bug has been harmless as hashmap nodes, which is only ones (?) that can cause a factory to produce more heap, are not linked in off_heap-list.

2015-11-30Remove ERTS_PRINT_INVALID from erts_print()Rickard Green
ERTS_PRINT_INVALID prevented file descriptor 0 to be used which could cause an empty crash dump.
2015-11-30erts: Remove unused include files from hash.cSverker Eriksson
Note that hash.c is quite "clean" from Erlang stuff and is used by erl_child_setup as well.
2015-11-27erts: Redesign grow/shrink thresholds of hash.cSverker Eriksson
1. Use load factor as indicator, not used buckets. Used buckets is a bad indicator as it makes the situation even worse with a bad hash function. Set grow_threshold to load factor of 160% as it roughly corresponds to the old 80% used bucket limit. 2. Never shrink table below initial size.

2015-11-27erts: Fix rare case of faulty heap fragment deallocationSverker Eriksson
after major GC. Can only be caused by distributed messages containing large maps. Bad map hashing will increase the risk.
