Added a global logger that make it possible to log
from the slave nodes (with "ease").
Also "fixed" the test case that failed on "older"
linux (Ubuntu 14.04). For now we let it skip
instead (we should really check the OS version).
Also corrected a couple of (ping-pong) cases for which
the buffer adjustments did not work.

Assumed the wrong success value ({ok, _} instead of ok) for the
api-to-connect-tcp test case.

Previously the "message interface" between the functions in
socket.erl and the nif-code (socket_nif.c) was "ad hoc".
This has now been changed so that we have a unified message
{'$socket', SockRef | undefined, Tag, Info}
This also has the added advantage of preparing the code for
when we start using the new select-fucntions (with which
its possible to specify your own message). This will be used
in order to get around our eterm "leak" (we will use a simple
counter, maintained in the nif, instead of the [Recv|Send|Acc]Ref
we generate in the erlang code today.

Added a ttest lib module for some common functions.
Added a process (server handler and reader processes) stats
printouts. So far only used by the server.
There is still a "leak". Its a term leak. Some of the
functions take a ref as argument (recv, send and accept for
instance). This is stored internally, by way of a call to
the enif_make_copy, in order to be used later in a select
call. Its not "released" though, until the environment is
released, which happens when the socket dtor callback function
is called.
Possible solution: We need to keep "temporary" environments (one
for each of the queues), which we can clear (basically we need two,
one that is currently used for new ref's and one for the old ref's).

"Dry fixed" the "same" problems as was found for nif_recv (missing
binary free(s)).
OTP-14831
|
|
Running valgrind, found a couple of cases when allocated
binaries where not released. Mostly when the recv failed
for some reason.
Also clear and free the environment associated with the
socket (resource) (in the _dtor callback function).

* Socket close callback
Only demonitor the closer if its local (close) and its not
a direct call. There was a spurious warning message.
* Down callback
Only process this event if the socket is not closed or closing.

The default read buffer size was 2K and has now been
increased to 8K.

The ping-pong merge had some problems...
|
|
Added config checks for the sctp struct field:
sctp_event_subscribe.sctp_authentication_event
Also, if-def'ed the code accordingly.
If-def'ed code to handle the (non-) existence of IP_PMTUDISC_PROBE
and IPV6_PMTUDISC_PROBE for the IP and IPv6 MTU_DISCOVER options.

Attempt to fix the the api_to_connect_tcp[4|6] test cases.
On some linux versions (Ubuntu 14), the backlog seems to not
work. No luck...

Added a socket close (actually shutdown(write)) for recv and
recvmsg for tcp.
OTP-14831
|
|
Added ping-pong test cases for UDP, small and medium, using
the sendto/recvfrom and sendmsg/recvmsg functions.
OTP-14831
|
|
When type = dgram, the functions recvfrom and recvmsg did not
properly handle socket close, cuaing the caller to hang
indefinitely.
OTP-14831

|
Some minor restructure of the ping-pong test cases in order
to not have duplicate the send and receive fun's.
OTP-14831
|
|
Added New ping-pong test cases using the sendmsg and recvmsg functions.
OTP-14831
|
|
The API for the sendmsg function has been updated to describe
the possible "partial success" of {ok, Remaining}.
OTP-14831
|
|
The sendmsg function attempts to send *one message*. But
its possible for the underlying software to fail to send
the *entire* message. So, instead of retrying itself, as
send does, the sendmsg function will now instead return
with {ok, Remaining}, leaving it to the caller to decide
what to do.
OTP-14831
|
|
When the send buffer was full (eagain), the send failed
(with the rather useless return of {ok, -1}) instead of
returning {error, eagain}.

Make it possible to open a file and send debug printouts to
(instead of stdout) for debug printouts from the nif-code.
OTP-14831

The ping-pong test case(s) now initiates the socket
buffers before they are connected (server: before listen is
called on the listen socket and client: before connect is called).
Also, we now include a length indicator in the messages, so
that we know how much to read.
OTP-14831

|
An "accepted" socket will inherit the parent (listen) socket's
buffer sizes (rBufSz, rCtrlSz and wCtrlSz).

We got some kind of send hang...
|
|
The send and recv test case triggered a two bugs. One was
that there was no re-selecting when only a portion of the data
was received (which meant that we stopped reading).
Also, the wrong 'current' (writer) was reset when demonitor
current reader after a successful read (which meant that
future readers would never have been monitored).

Make more use the evaluator functions for communication between
processes. Specifically, between the server and its handler processes
in the sc_rc_receive_response_tcp test cases(s).
OTP-14831
|
|
Use the evaluator functions for communication between processes
also for communication between "slave" processes (on other nodes).
OTP-14831
|
|
All test cases has been updated using the new evaluator module
(and their macros).
OTP-14831
|
|
Add a "proper" evaluator module and adapted a couple
of test cases to use that instead.
OTP-14831
|
|
Updated the socket (remote) close test case(s) sc_rc_receive_response_tcp.
Now has three (remote) client connecting.

Updated the socket (local) close test case(s) sc_lc_acceptor_response_tcp
with the new evaluator interface functions.

Updated the basic api test cases api_b_send_and_recv_tcp4 and
api_b_sendmsg_and_recvmsg_tcp4 with the new evaluator interface
functions.
OTP-14831

Added simple evaluator interface functions, so that it is
simple for evaluators to interact (and unified).
Only two test cases so far...
OTP-14831
|
|
Added two remote close socket closure test cases (for
IPv4 TCP): sc_rc_recv_response_tcp4 and sc_rc_recvmsg_response_tcp4.
OTP-14831
|
|
Add test cases for tcp local socket close for the accept function.
OTP-14831
|
|
Add test cases for udp local socket close for UDP recvfrom and
recvmsg.
OTP-14831
|
|
When calling the recvfrom function when there is no data,
we should be made wait (for the specified amount of time).
But this did not work because the "current reader" structure
was not initiated.
OTP-14831
|
|
The receive response local close tcp cases was extended
wityh two more handler (readers).
OTP-14831
|
|
Add name to evaluator printouts. Also added timetraps to all test-
cases to shorten the time to wait in case a test case fails.
