2010-11-12Fix socket_t::recv() hang scenario where initial call to process_commands() ↵Marc Rossi
eats signal Added block boolean var to second process_commands() invocation for blocking sockets instead of always using true. This prevents the process_commands() call from hanging when a message is received with an empty queue after the call to xrecv() but prior to the initial call to process_commands() invoked when ++ticks == inbound_poll_rate.

2010-11-05signaler renamed to mailboxMartin Sustrik
For historical reasons queue to transfer commands between threads was called 'signaler'. Given that it was used to pass commands rather than signals it was renamed to 'mailbox', see Erlang mailboxes. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2010-11-05slots renamed to tidsMartin Sustrik
Threads were so far identified by integers called 'slots'. This patch renames them to more comprehensible 'tid's (thread IDs). Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2010-11-04Automatically resize signalling socket buffer if fullMartin Lucina
If the socketpair used by signaler_t fills up, this can lead to deadlock. This patch provides partial resolution by attempting to resize SO_SNDBUF on the writer side, and if that fails we shall at least assert rather than hang. I've also refactored the signaler_t code to make the platform-dependent parts clearer and have tested both the MSG_DONTWAIT and standard POSIX path in recv. The Win32 implementation currently does not implement resizing as I'm not convinced that it's safe, but it will also assert like other platforms if signaler_t::send() cannot succeed. The OpenVMS implementation has been carried forward but is untested. Signed-off-by: Martin Lucina <mato@kotelna.sk>

devpoll_t used this constant to determine how many events to retrieve from the poller in one go. The implementation was changed not to depend on this constant. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

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. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
