|
|
The message_queue_data option can have the values
- off_heap
- on_heap
- mixed
|
|
|

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.

to support other terms, not just maps

1. Change order between mul and div to not lose too much
in integer divisions.
2. Fix estimation in DEBUG to really be an *under* estimation.

that could cause the static factory to overflow
Fix: Introduce a new factory mode FACTORY_TMP

Calculate hashvalue in load-time for constant process dictionary gets.

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.

* maint:
Remove ERTS_PRINT_INVALID from erts_print()
|
|
* rickard/erts-print/OTP-13150:
Remove ERTS_PRINT_INVALID from erts_print()
|
|
ERTS_PRINT_INVALID prevented file descriptor 0 to be used which
could cause an empty crash dump.
|
|
Note that hash.c is quite "clean" from Erlang stuff
and is used by erl_child_setup as well.

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.

after major GC.
Can only be caused by distributed messages containing large maps.
Bad map hashing will increase the risk.

erts: More testcases for map binary_to_term/1
erts: Fix maps decode in erlang:binary_to_term/1

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.

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.
