fork() support is optional and its availability is correctly detected at
contfigure time.
But test_fork was all always built, preventing build for targets that do
not provide fork() from building successfully.
This pacth fixes the autotools on this point.
Has some bits commented out due to #939, now work.
Note: there is an issue in libzmq when binding/unbinding or
connecting/disconnecting (I did not investigate deeper) the
same socket several times. Even closing the socket with zero
linger, zmq_ctx_term will block. The workaround in this test
case is to close the sockets for each test step.
Specifically:
* zmq_event_t should not be used internally in libzmq, it was
meant to be an outward facing structure.
* In 4.x, zmq_event_t does not correspond to monitor events, so
I removed the structure entirely.
* man page for zmq_socket_monitor is incomplete and the example
code was particularly nasty.
* test_monitor.cpp needed rewriting, it was not clean.
- this failing test was confusing users
- ZMTP v3.0 now does not define resources at all
- resources, along with other unimplemented aspects moved to
RFC 37 ZMTP v3.1
The new options allows querying the maximum allowed number of sockets.
This is system dependent and cannot be encoded in the include file as a
preprocessor macro: for ZMQ_USE_SELECT, this depends on the FD_SETSIZE
macro at time of library compilation, not at time of include file use.
- renamed test_stream_disconnect_notifications (too long!)
- removed print statements in that test case
- fixed Makefile.am for test_zap_ipc_creds (was not building)
When a ZMQ_STREAM socket connection is broken (intentionally, via `shutdown()`
or accidentally via client crash or network failure), there is no way for the
application to dertermine that it should drop per-connection data (such as
buffers).
This contribution makes sure the application receives a 0-length message to
notify it that the connection has been broken. This is symmetric with the
process of closing the connection from within the application (where the
application sends a 0-length message to tell ZeroMQ to close the connection).

This fixes the test on Mac OS X and SmartOS (probably other Solarises).
Also updates the sockets using ipc: to use DEALER sockets instead
of PAIR sockets.
- This seems redundant; is there a use case for NOT providing
the IPC credentials to the ZAP authenticator?
- More, why is IPC authentication done via libzmq instead of ZAP?
Is it because we're missing the transport type on the ZAP request?
Another take on LIBZMQ-568 to allow filtering IPC connections, this time
using ZAP. This change is backward compatible. If the
ZMQ_ZAP_IPC_CREDS option is set, the user, group, and process IDs of the
peer process are appended to the address (separated by colons) of a ZAP
request; otherwise, nothing changes. See LIBZMQ-568 and zmq_setsockopt
documentation for more information.
