The dist messages EXIT, EXIT2 and MONITOR_DOWN have been
updated with new versions that send the reason term as
part of the payload of the message instead of as part
of the control message.
This allows the decode of the reason to be done by the
receiving process instead of the dist entry which in turn
makes it possible for multiple decodes to be done in
parallel.
This change is done in order to make it easier to fragment
the potentially large payload of EXIT, EXIT2 and MONITOR_DOWN
into multiple distribution messages.

* Move the node name check earlier
* Check while still a list
* Export allowed check function
* Make allowed check function handle atom and list mixes

* sverker/send-tick/OTP-14681:
kernel: Fix and improve send_tick logic
|
|
to replace DFLAGS_STRICT_ORDER_DELIVERY
and remove that compile time dependency.
|
|
and remove use in dist_util:check_mandatory
|
|
to a simple 'band' operation into ChosenFlags
and no need to remember old 'this_flags' and 'other_flags'.
|
|
for kernel to ask erts about distribution flags
and keep this info in one place.
|
|
No need to clear them as they cannot be set.
|
|
|
|
and remove ugly encoding fallback as {fun, ...}
DFLAGS_NEW_FUN_TAGS has been supported by vm/erl_interface/jinterface
since R13 or even older.
Renamed test case obsolete_funs to term2bin_tuple_fallbacks
and removed test for {fun,...} fallback
and added missing test for bitstring fallback {Binary, Bits}.

Problem 1: Tick was not sent to hidden when pending sends. Don't hidden
need the tick in order to reply?
Problem 2: Written packets (#tick.write) was increased even when tick
was suppressed due to pending sends.
Code rewritten to handle outgoing and incoming separate.

by separating the constant values into tuple ConData.
and that exposed the fact that TcpAddress and MyNode
where not used.

Add descriptive shutdown reasons when an incoming distribution
connection is rejected because it is not on the "allowed" list or
because it has an incorrect cookie. These error reasons can be seen
after calling net_kernel:verbose(1).
Distinguishing these failures is valuable, because the log message
printed is otherwise identical.

* henrik/update-copyrightyear:
update copyright-year
|
|
to let future nodes know that we can handle
NEW_PID_EXT, NEW_PORT_EXT and NEWER_REFERENCE_EXT.
|
|
|
|
These error reasons can be seen in the logs after calling net_kernel:verbose(1).

This is just a preparation to allow detection of older nodes
that do not understand maps (R16 and older).

* bg/dist_utils:
dist_utils: Eliminate crash when list_to_existing_atom/1 fails
|
|
In the following scenario list_to_existing_atom/1 may crash
during handshake:
Start a node in one window:
erl -sname adam@localhost
Start another node in another window:
erl -sname bertil
In this node, ping the first node (use the actual hostname
in the command):
net:ping(adam@hostname).
There will be an error report similar to:
=ERROR REPORT==== 27-May-2010::15:03:14 ===
Error in process <0.40.0> on node 'bertil@hostname' with exit value: {badarg,[{erlang,list_to_existing_atom,
["adam@localhost"]},{dist_util,recv_challenge,1},{dist_util,handshake_we_started,1}]}
Eliminate the crash and the error report by catching the call to
list_to_existing_atom/1 and do a clean shutdown if it fails.
