Symptom:
Heart kills exiting emulator before is has flushed all ports
and with HEART_KILL_SIGNAL=SIGABRT it may also produce
unnecessary core dumps from doing init:reboot() for example.
Problem:
Heart port is closed together with all the others in handle_reap_ports()
which is detected by heart OS process.
Solution 1:
Leave the heart port alone in handle_reap_ports() and let it be closed
by OS when emulator exists. It doesn't need to be flushed anyway.
Solution 2:
When heart OS process gets EOF on connection let it wait max 5 seconds
for emulator process to self terminate before trying to kill it.

Similar bug as for bxor fixed by abc4fd372d476821448dfb9
Ex:
1> io:format("~.16B\n", [-16#1110000000000000000 band (-1)]).
-1120000000000000000
Wrong result for
(-X bsl WS) band -Y.
where
X is any positive integer
WS is erlang:system_info(wordsize)*8*N where N is 1 or larger
Y is any positive integer smaller than (1 bsl WS)
Fix:
The subtraction of 1 (for 2-complement conversion)
must be carried along all the way to the last words.

A bug for SSH_MSG_EXT_INFO was fixed both for client and server. Before that fix, wrong
option was read for the information sent to the peer.
This commit adapts the option checking so that the correct option now used is available
not only for servers but also for clients.

The wrong set of supported public keys was sent to the client.

* john/erts/OTP-20.3.8/minusminus_trapping/OTP-15371:
Optimize operator '--' and yield on large inputs
|
|
The removal set now uses a red-black tree instead of an array on
large inputs, decreasing runtime complexity from `n*n` to
`n*log(n)`. It will also exit early when there are no more items
left in the removal set, drastically improving performance and
memory use when the items to be removed are present near the head
of the list.
This got a lot more complicated than before as the overhead of
always using a red-black tree was unacceptable when either of the
inputs were small, but this compromise has okay-to-decent
performance regardless of input size.

Fix include-path regression caused by dd0a39c
|
|
Include paths don't actually affect code generation in any way, but
it's reasonable for a build tool like rebar3 to recompile when the
include paths change. This commit restores the old behavior without
the +deterministic flag.
