* fixes #459 SUB should be more aggressive about discarding messagesGarrett D'Amore2018-05-21
| | | | | | | | | As part of this code fix, we needed to add filtering support to the msgq_tryput code path -- it turns out that code path was bypassing the filterfn altogether. Eventually we'll remove all this filtering stuff from the msgq code and replace it with inline filtering directly in sub.
* fixes #449 Want more flexible pipe eventsGarrett D'Amore2018-05-17
| | | | | | | | | This changes the signature of nng_pipe_notify(), and the associated events. The documentation is updated to reflect this. We have also broken the lock up so that we don't hold the master socket lock for some of these things, which may have beneficial impact on performance.
* fixes #419 want to nni_aio_stop without blocking (#428)Garrett D'Amore2018-05-15
| | | | | | | | | | | | | | | | * fixes #419 want to nni_aio_stop without blocking This actually introduces an nni_aio_close() API that causes nni_aio_begin to return NNG_ECLOSED, while scheduling a callback on the AIO to do an NNG_ECLOSED as well. This should be called in non-blocking close() contexts instead of nni_aio_stop(), and the cases where we call nni_aio_fini() multiple times are updated updated to add nni_aio_stop() calls on all "interlinked" aios before finalizing them. Furthermore, we call nni_aio_close() as soon as practical in the close path. This closes an annoying race condition where the callback from a lower subsystem could wind up rescheduling an operation that we wanted to abort.
* fixes #331 replace NNG_OPT_RAW option with constructorGarrett D'Amore2018-04-04
| | | | | | | | | | | | | This makes the raw mode something that is immutable, determined at socket construction. This is an enabling change for the separate context support coming soon. As a result, this is an API breaking change for users of the raw mode option (NNG_OPT_RAW). There aren't many of them out there. Cooked mode is entirely unaffected. There are changes to tests and documentation included.
* fixes #329 type checking not done for setoptGarrett D'Amore2018-04-04

* fixes #301 String option handling for getoptGarrett D'Amore2018-03-20

* fixes #296 Typed options should validate option typeGarrett D'Amore2018-03-20
| | | | | | | | | | | | | fixes #302 nng_dialer/listener/pipe_getopt_sockaddr desired This adds plumbing to pass and check the type of options all the way through. NNG_ZT_OPT_ORBIT is type UINT64, but you can use the untyped form to pass two of them if needed. No typed access for retrieving strings yet. I think this should allocate a pointer and copy that out, but that's for later.
* fixes #295 boolean options should use C99 bool typeGarrett D'Amore2018-03-18
| | | | | | | | | | | fixes #275 nng_pipe_getopt_ptr() missing? fixes #285 nng_setopt_ptr MIS fixes #297 nng_listener/dialer_close does not validate mode This change adds some missing APIs, and changes others. In particular, certain options are now of type bool, with size of just one. This is a *breaking* change for code that uses those options -- NNG_OPT_RAW, NNG_OPT_PAIR1_POLY, NNG_OPT_TLS_VERIFIED.
* CMake & CPack improvements.Garrett D'Amore2018-02-21
| | | | | | | | | These are incremental updates... we avoid using install() in the subdirectories, so that we can adapt properly to them in the single parent directory. We have started some of the work to improve support for CPack. This is still not yet done, but work in progress.
* fixes #234 Investigate enabling more verbose compiler warningsGarrett D'Amore2018-02-14
| | | | | | | We enabled verbose compiler warnings, and found a lot of issues. Some of these were even real bugs. As a bonus, we actually save some initialization steps in the compat layer, and avoid passing some variables we don't need.
* fixes #173 Define public HTTP server APIGarrett D'Amore2018-02-01
| | | | | | | | | | | | | | | | | | | | | | | This introduces enough of the HTTP API to support fully server applications, including creation of websocket style protocols, pluggable handlers, and so forth. We have also introduced scatter/gather I/O (rudimentary) for aios, and made other enhancements to the AIO framework. The internals of the AIOs themselves are now fully private, and we have eliminated the aio->a_addr member, with plans to remove the pipe and possibly message members as well. A few other minor issues were found and fixed as well. The HTTP API includes request, response, and connection objects, which can be used with both servers and clients. It also defines the HTTP server and handler objects, which support server applications. Support for client applications will require a client object to be exposed, and that should be happening shortly. None of this is "documented" yet, bug again, we will follow up shortly.
* fixes #143 Protocols and transports should be "configurable"Garrett D'Amore2017-11-02
This makes all the protocols and transports optional. All of them except ZeroTier are enabled by default, but you can now disable them (remove from the build) with cmake options. The test suite is modified so that tests still run as much as they can, but skip over things caused by missing functionality from the library (due to configuration). Further, the constant definitions and prototypes for functions that are specific to transports or protocols are moved into appropriate headers, which should be included directly by applications wishing to use these. We have also added and improved documentation -- all of the transports are documented, and several more man pages for protocols have been added. (Req/Rep and Surveyor are still missing.)
