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.

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.

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.

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.

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 socket (remote) close test case(s) sc_rc_receive_response_tcp
with the new evaluator interface functions.

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

Updated the socket (local) close test case(s) sc_lc_receive_response_tcp
with the new evaluator interface functions.
OTP-14831

Updated the socket close test case(s) sc_cpe_socket_cleanup
with the new evaluator interface functions.
OTP-14831

Updated the basic api timeout test case(s) api_to_maccept_tcp
with the new evaluator interface functions.
OTP-14831
|
|
Updated the basic api timeout test case api_to_connect_tcp
with the new evaluator interface functions.
OTP-14831
|
|
Updated the basic api option test case
api_opt_simple_otp_controlling_process
with the new evaluator interface functions.
OTP-14831
|
|
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.

The level argument for IPv6 can be either SOL_IPV6 or
IPPROTO_IPV6, whichever is defined. But it was hard-
coded to SOL_IPV6, which is not defined on FreeBSD.

Fixed a number of issues regarding monitor handling.
Monitors are now wrapped in its own type (ESockMonitor).
This is hopefully temporary!
The reason for this is that there is no way to "initialize"
a monitor after a demonitor. This could mean that after a
successful demonitor, you could still get a down-callback,
and thenh compare with, for instance, ctrlMOn field and get
a match, even though it was just (successfully) demonitor'ed.
To make debugging easier, the monitor and demonitor calls
are now wrapped in their own functions, with debug printouts
before and in case of failure, also after the actual calls
Also, fixed a number of problems with cancel, where monitors
where left still active after cleaning up current and active
reader, writer and acceptor.

Fixed more issues regarding closing sockets. Specifically
with respect to recv calls.
Also, added demonitor for all *current* processes.
Also fixed a buffer overflow problem when writing an
warning message (the timestamp buffer was not large
enough).

The handling of terminating controlling-process was
incomplete.
Also added state check (CLOSED and CLOSING) in all
nif-functions to prevent access for a closed (or
closing) socket.
OTP-14831
|
|
Added preliminary documentation for the function socket:supports/0,1,2,3.
It still does not generate proper doc for supports/3 (the last
arg, Opt, don't get a type).
OTP-14831
|
|
The supports function now also handles testing for SCTP and
IPv6 support. Basic test at the moment, but better then nothing.
OTP-14831
|
|
"Completed" the socket options part of the supports function.
OTP-14831
|
|
Add the options for level socket (full), ip and ipv6 to the
supports function.
OTP-14831

Added the first three socket (level socket) options to the
supports function(s).

verify that the caller is actually the current controlling_process.

Add explicitly handling the default case, when not flags
are provided (value of zero).

Internally in the socket module we accessed domain, type and
protocol for an open socket. But as it turns out, domain (family)
is not actually available as a socket option on all platforms.
FreeBSD in this case. So, since we store these values in the socket
descriptor anyway, we switch to use these values for our internal
use instead.

Add support for otp level socket options rcvbuf, rcvctrlbuf and
sndctrlbuf. These options define default sizes for these
buffers.
The 'rcvbuf' is used when receiving messages when calling
the recv, recvfrom and recvmsg functions.
The 'rcvctrlbuf' is used for the control message header info
when calling the recvmsg function.
The 'sndctrlbuf' is used for the control message header info
when calling the sendmsg function.

Removed some cruft. Also tried, without success, to fix the
build issue ("Error file: cannot find module exporting type").
It may be because of a spec-file issue.
Finally fixed the setopt doc. It did not have a seperate clause
for clause 8 (the fallback clause that takes level and key as
integer).
|
|
Added missing SCTP type (for assoc id) and updated sento doc
(missing clauses).
