Using magic refs for big timers caused too large a stress on
the off_heap GC implementation to be viable, so it was never
enable. The code is now broken because of other changes to
we might as well remove it.

to increase the probablity of a nice badarg
from erlang:port_control.

Apply type optimizations across local function calls
|
|
This commit lets the type optimization pass work across functions,
tracking return and argument types to eliminate redundant tests.

The is_function2 instruction is executed surprisingly
frequently when running dialyzer or the compiler. It
cannot hurt to optimize it a little.

When the schedulers never go to sleep (and thus never polls)
it may be that the fds in schedulers poll-sets are never polled.
Before this commit, this was solved by starting a timer when an
overload was detected. This had issues as overloads were not always
detected in time. So this commit reverts to the pre OTP-21 behaviour
so keep a global counter makes that the poll is called when it should.

There seems to be an incorrect merge conflict resolution
in abde22933f5a that merged maint to master. Dumping of
references (and possibly other terms) were broken.

If the main lock is not taken then any process running
on a dirty scheduler may cause all kinds of problems.

This flag allows logger and other components to set the
process which log messages from ERTS are to be sent.

Fix passing large integers as base to integer_to_X/2
|
|
I noticed this seconds after merging... :(
|
|
* maint:
Implement integer_to_list/2 and integer_to_binary/2 as CIFs
Accept base in all integer-printing functions
Document cleanup semantics for atomics and counters
|
|
This makes them roughly as fast as integer_to_list/1 and
integer_to_binary/1.

otherwise gc may move the binary data and make 'src_bytes' invalid.

Custom message format for enif_select
|
|
Make sure to flush all queued emulator logger messages
before starting the test. The trap_exit_badarg could sometimes
leave messages and since the handler and messages now are
handled in different processes this becomes a problem.
