The nature of aux work is such that dirty schedulers should not
attempt to perform it. Modify the code to ensure that dirty schedulers
avoid aux work.
Also fix an incorrect assumption about the size of a Uint in the
ErtsDirtySchedId type.

Bug introduced in ce8279d6a48d41f9.
Thank you valgrind.

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
|
|
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.

Remove ERTS_PRINT_INVALID from erts_print()

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

* 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
|
|
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.
|
|
This should be a harmless and compatible API change.

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.

|
* lukas/erts/win32_bool_fix/OTP-13079:
erts: bool is a reserved word, use boolean instead
|
|
Not needed as it is always set to erts_this_dist_entry (on net_kernel).
|
|
There is no guarantee that the ptab-slot in not reused
when we finally deallocates the process struct.

Fix build fail when enabling distribution debug messages

A new {line_delimiter, byte()} option allows line-oriented TCP-based
protocols to use a custom line delimiting character. It is to be
used in conjunction with {packet, line}.
This option also works with erlang:decode_packet/3 when its first argument
is 'line'.

Problem #1 Goodfit was crippled by the fact that destroying_mbc()
was called _before_ the carriers was unlinked from mbc_list.
Problem #2 destroying_mbc() was called for carriers that later could be
resurrected from dc_list without a matching call to creating_mbc().
This was mostly a practical problem for the new test case
alloc_SUITE:migration that use the callbacks to create/destroy a mutex.
Solution:
destroying_mbc() is now only called just before a carrier is
destroyed (deallocated or put in mseg cache).
remove_mbc() is called both (like before) when inserted into cpool
but now also when last block is freed and mbc is scheduled for
destruction but may later be resurrected from dc_list.

Problem #1: Seems the dc_list check did end up as dead code by mistake.
Solution: goto check_dc_list
Problem #2: crr->cpool.max_size was set to zero for all carriers in
dc_list, which meant no carriers were ever resurrected by cpool_fetch.
Solution: Do not use callback 'largest_fblk_in_mbc' to set max_size
as it will always return 0 (due to problem #3).
Problem #3: Resurrected carriers were broken as their one free block
was not linked.
Solution: Link free block when fetching carrier from dc_list.

Another process may already have been placed in this slot
since the free och the process struct can be scheduled for
later.

If the process stack contained a match state
the print function would crash the vm as it was not
recognized by tag_val_def().
Add new MATCHSTATE_DEF returned by tag_val_def().
All other callers either ignore it or has a default
clause to handle invalid terms.

Lots of pthread platforms unnecessarily falled back on the pipe/select
solution. This since we tried to use the same monotonic clock source
for pthread_cond_timedwait() as used by OS monotonic time. This has
been fixed on most platforms by using another clock source.
Darwin can however not use pthread_cond_timedwait() with monotonic
clock source and has to use the pipe/select solution. On darwin we
now use select with _DARWIN_UNLIMITED_SELECT in order to be able to
handle a large amount of file descriptors.
