2012-05-20Implement SP wire protocolspMartin Lucina
Implements the SP wire protocol, and infrastructure for legacy wire protocol support. Also added an XS_SERVICE_ID socket option to set the service id and renamed the XS_PROTOCOL option to XS_PATTERN_VERSION. The following pattern versions are supported: PAIR: v3 PUBSUB: v1 (legacy), v4 REQREP: v2 PIPELINE: v3 SURVEY: v2 Note that all existing pattern versions have been bumped by 1 to allow for use of legacy protocols (otherwise there would be no way to distinguish between e.g. PUBSUB v3 and PUBSUB v3 using SP).

- version bump - ABI version bump - NEWS updated Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-05-06C prototype for xs_init fixedMartin Sustrik
The function was erroneously declared as xs_init() instead of xs_init(void). Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-21xs_shutdown implementedMartin Sustrik
This patch allows for partial shutdown of the socket. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-17XS_SURVEY_TIMEOUT socket option added.Martin Sustrik
It can be used to timeout the survey. Value is in milliseconds and -1 means infinite (default). Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-17"Survey" pattern implementedMartin Sustrik
Survey pattern is "multicast with reply". There are two roles: surveyor and respondent. Surveyor publishes a survey which gets delivered to all connected respondents. Each repondent can send a response to the survey. All the responses are delivered to the original surveyor. Once the surveyor decides that the survey is over (e.g. deadline was reached) it can send initiate survey. Late responses from old surveys are automatically discarded by the surveyor socket. Socket types: SURVEYOR, XSURVEYOR, RESPONDENT, XRESPONDENT Patch also includes a test program with surveoyr, two respondents and an intermediary device.

2012-04-14Separate subscription forwarding from SUB-side filteringMartin Sustrik
- subscription forwarding is handled by XSUB socket - filtering is handled by SUB sockets - subscriptions are decoupled from filter engines - filter doesn't have to be able to enumarate the subscriptions (no sf_enumerate function) Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-06EMTHREAD error code removedMartin Sustrik
libxs (as opposed to libzmq) requires at least one I/O thread per context. Thus, "no I/O thread available" error doesn't make sense anyome. This patch removes the code and the documentation. It keeps the definition of EMTHREAD itself for backward compatibility. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-05XS_PLUGIN and XS_FILTER implementationMartin Sustrik
This patch introduces following features: - XS_PLUGIN context option to add plugins to libxs - XS_FILTER option to switch between different filter types - Automatic loading of plug-ins is *not* implemented. From the implementation point of view: - standard prefix filter is implemented as a pluggable filter - trie_t and mtrie_t are joined into a single class - the code for 0MQ/3.1 compatibility is left in in the form of comments - new test for testing re-subscriptions is added Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-04-040MQ/2.1 wire format compatibility implementedMartin Sustrik
- XS_PROTOCOL option added - libxs ignores when unused flags are set to 1 (0MQ/2.1 bug) - compatibility tests added Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2012-03-28XS_KEEPALIVE options addedMartin Sustrik
This option allows to turn on TCP keepalives on the underlying connections. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-03-13'timeout' parameter in xs_poll changed to intMartin Sustrik
Originally, the parameter was of type long which is incompatible with POSIX poll() function. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-03-13xs_utils cleanup 2/2 (remove xs_utils.h)Martin Lucina
Moved xs_stopwatch_* functions from xs_utils.cpp/xs_utils.h, and removed those files. This leaves us with a single header file for libxs. Signed-off-by: Martin Lucina <martin@lucina.net>

2012-03-13Drop libxszmq, keep only libzmq compatibility library (--enable-libzmq)Martin Lucina
This simplifies the options for new users; either use libxs APIs or build with --enable-libzmq and get libzmq 2.1 emulation. Signed-off-by: Martin Lucina <martin@lucina.net>
2012-03-13io_threads argument removed from xs_init()Martin Sustrik
The argument was changed to a context option (XS_IO_THREADS). 0MQ compatibility mode sets the option and ensures that there's at least one I/O thread present. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2012-02-22Added optional drop-in libzmq libraryMartin Lucina
Enabled using --enable-libzmq-compat, this installs a drop-in libzmq library and headers. Not enabled by default since it will overwrite any existing libzmq install. Signed-off-by: Martin Lucina <martin@lucina.net>

2011-11-05Version changed to 3.1.0Martin Sustrik
This version downgrade is done because of the previous refatoring. It removed all the new features and reintroduced some of the old ones (identities). Thus, it made trunk much closer to existing 3.0 branch than it used to be. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-07-17GENERIC socket type and COMMAND flag addedMartin Sustrik
GENERIC allows to use 0MQ as a dumb networking framework. It provides user with connect/disconnect notifications. Also, each inbound message is labeled by ID of the connection it originated from. Outbound messages should be labeled by the ID of the connection to send them to. To distinguish connect/disconnect notifications from common messages, COMMAND flag was introduced.
