The test case cover_SUITE:slave_start_slave often fails on a test host
(windows) due to a hanging node from an earlier test run. In the first
test, the slave fails to start (boot_timeout?) and is never connected
to the test node. The attempt at cleaning up used nodes() to find
which slaves to kill - so in the case where the slave was never
connected it was never killed. This is no changed so each slave is
explicitly killed by name - no matter if it is pingable or not.
|
|
Test nodes are started with erlang:open_port/2, using the -detached
option to erl. -detached causes the port returned from open_port/2 to
be closed automatically. Some test cases failed occasionally with a
badarg when attempting to close the port with erlang:port_close/1. To
avoid this the call to port_close/1 is now removed.

* ak/fix-cpu-overhead-of-timer-server/OTP-11053:
fix excessive CPU consumption of timer_server
|
|
I've found stdlib's timer to burn CPU without good reason. Here's what
happens.
The problem is that it sleeps in milliseconds but computes time in
microseconds. And there is bug in code to compute milliseconds to
sleep. It computes microseconds difference between now and nearest
timer event and then does _truncating_ division by 1000. So on average
it sleeps 500 microseconds _less than needed_. On wakeup its checks do
I have timer tick that already occurred? No. Ok how much I need to
sleep ? It does that bad computation again and gets 0
milliseconds. So next gen_server timeout happens right away only to
find we're still before closest timer tick and to decide to sleep 0
milliseconds again. And again and again.
This commit changes division to pick ceiling of ratio rather than
floor. So that we always sleep not less then difference between now
and closest event time.

Encode Erlang source files with non-ascii characters in UTF-8

Prevent loss of objects after the extension marker

In test case log, the red error notification may sometimes be
truncated. This commit adds a link from this printout to the end of
the log where the full error description and stacktrace i written.
|
|
This commit adds ?MAX_IMPORTANCE to error notifications in the test
case log, and it makes sure that the printout says "CT Error
Notification".
Printouts from cth_log_redirect (sasl and error_reports) uses
?STD_IMPORTANCE and states "System" in the printout.

In particular, remove timing dependence by using diameter_reg:wait/1 to
wait on the term registered by diameter_{tcp,sctp} when opening a
listening socket.
|
|
Note that the semantics of client:connect/1 have changed slightly: the
second element in an argument 3-tuple is a remote address, the local
address being the transport module's default. Previously it was
interpreted as a common local/remote address.
|
|
Use the default address address (as selected by gen_tcp) if none is
configured, passing it in the new 'connected' message introduced by the
previous commit.
The corresponding update to diameter_sctp has to wait until problems
with inet:sockname/1 are resolved: the function currently only returns
one address, and sometimes {0,0,0,0}. See OTP-11018.
|
|
A transport module can return a local address list from its start/3
function in order to specify addresses to be used as Host-IP-Address
during capabilities exchange. Now allow addresses to be communicated in
a 'connected' message in the case of a connecting transport, so that
diameter_tcp (in particular) can make local address configuration
optional, communicating the gen_tcp default after connection
establishment instead.
|
|
The file module communicates with a file io server with the following
protocol for file operations:
> {file_request,From,ReplyAs,Request}
< {file_reply,ReplyAs,Reply}
The ReplyAs value is sent by the client side to match against when
receiving the reply and is otherwise left untouched and passed as is by
the server.
This commit enables receive optimizations by using the reference of the
server monitor, changing the protocol to:
> {file_request,From,MonitorRef,Request}
< {file_reply,MonitorRef,Reply}
As the shape of the messages is not changed, backwards compatibility is
not a concern.

A service process maintains a table keyed on watchdog process pids. When
a watchdog process dies the corresponding entry should be removed but
this was broken in commit f115a9f7, causing entries with watchdog state
DOWN to accumulate.
Watchdog processes die as a result of diameter:remove_transport/2, or
when a peer reestablishes a connection in the listening case. Neither is
typically a frequent occurrence.
The fault manifests itself in the return value of
diameter:service_info(SvcName, transport), which displays entries for
watchdog processes that are no longer alive.
