Solution: add API and ZMQ_EVENT_PIPES_STATS event which generates 2
values, one for the egress and one for the ingress pipes respectively.
Refactor the events code to be able to send multiple values.
Solution: when a connection breaks and ZMQ_RECONNECT_IVL is set to -1,
which means a reconnection will not be attempted, send a message from
the I/O thread to the application thread to make the socket call
term_endpoint, which is the equivalent of manually calling
zmq_disconnect.
This way subsequent zmq_connect call to the same endpoint will attempt
again to do a connection.
Otherwise, for some socket types like SUBs, those new connects will
fail as the endpoint is recorded, despite the connection having been
permanently closed.
Add test cases to exercise this corner case with TCP and IPC.
Of course people still "can" distributed the sources under the
LGPLv3. However we provide COPYING.LESSER with additional grants.
Solution: specify these grants in the header of each source file.
Copyrights had become ads for Sustrik's corporate sponsors, going against the original
agreement to share copyrights with the community (that agreement was: one line stating
iMatix copyright + one reference to AUTHORS file). The proliferation of corporate ads
is also unfair to the many individual authors. I've removed ALL corporate title from
the source files so the copyright statements can now be centralized in AUTHORS and
source files can be properly updated on an annual basis.
Compiling without warnings is a good goal, because it makes
new warnings (which probably indicate bugs) stand out rather
than getting lost in the spam.
My fixes fall into two categories:
- Adding (void) casts of unused parameters, where their
unusedness seems like a TODO (or in some cases a bug?).
- Removing parameter names altogether, where the function
is clearly a stub that will never use its parameters.
Should be no change in behavior.
It didn't seem straightforward to use any of the existing process calls, so I have added a new command to command_t and friends called detach. This instructs the socket_base to remove the pipe from it's pipe list. The session base stores a copy of the outpipe, and will resend the bind command on reconnection. This should allow balancing again.
This is a preliminary patch allowing for socket-type-specific
functionality in the I/O thread. For example, message format
can be checked asynchronously and misbehaved connections dropped
straight away.

So far, there was a pair of unidirectional pipes between a socket
and a session (or an inproc peer). This resulted in complex
problems with half-closed states and tracking which inpipe
corresponds to which outpipe.
This patch doesn't add any functionality in itself, but is
essential for further work on features like subscription
forwarding.

Reaper thread destroys the socket asynchronously.
zmq_term() can be interrupted by a signal (EINTR).
zmq_socket() will return ETERM after zmq_term() was called.

The meat of the patch was contributed by Douglas Creager.
Martin Sustrik implemented storing peer options in inproc
endpoint repository.

HP's version of STL doesn't allow for initialisation of basic_string
(blob_t) using NULL pointer, while SGI's implementation is OK with
that. Fixed.

Threads were so far identified by integers called 'slots'.
This patch renames them to more comprehensible 'tid's (thread IDs).

With SunStudio's implementation of STL basic_string constructor
doesn't accept NULL as a parameter even though size of string
is set to zero. Fixed.

1. ZMQ_LINGER option can be set/get
2. options are part of own_t base class rather than being declared
separately by individual objects
3. Linger option is propagated with "term" command so that the
newest value of it is used rather than the stored old one.
4. Session sets the linger timer if needed and terminates
as soon as it expires.
5. Corresponding documentation updated.
