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>
2012-03-29Version and ABI bumped to 1.0.1v1.0.1Martin Sustrik

Signed-off-by: Martin Lucina <martin@lucina.net>
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>
2012-03-13io_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>
2012-02-21Version bumped to 1.0.0Martin Sustrik

2012-02-16ZMQ_REENTRANT functionality removedMartin Sustrik
It doesn't play well with multipart messages. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-02-16Names of context options shortenedMartin Sustrik
Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2012-02-16XS_CTX_MAX_SOCKETS option implementedMartin Sustrik
To implement context options properly, initialisation of context is postponed till creation of the first socket. In the meantime it is possible to set socket options. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
