The new time warp safe option is safe_fixed_monotonic_time which
gives erlang:monotonic_time().
The safe_fixed option was also slightly changed. It now gives
erlang:timestamp() instead of erlang:now(). This has however
not been documented, so it is considered a compatible change.
The above effects both ets, and dets.
This commit also include the bugfix OTP-13239 for
dets:info(Tab, safe_fixed). The timestamp in the result returned
by dets:info(Tab, safe_fixed) was unintentionally broken as a
result of the time API rewrites in OTP 18.0.

New timestamp options for trace, sequential trace, and
system profile:
- monotonic_timestamp
- strict_monotonic_timestamp

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.

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

|
|
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.

There is no guarantee that the ptab-slot in not reused

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

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.
