* fixes #1171 message header could be inlined in the message structureGarrett D'Amore2020-02-26
| | | | | This uses a maximum 64-byte header and should avoid allocations and cache misses, leading to a small performance boost overall.
* fixes #1156 Message cloning could help reduce copies a lotGarrett D'Amore2020-01-20
| | | | | | | | | | | | This introduces reference counting on messages to reduce the data copies. This should have a marked improvement when moving large messages through the system, or when publishing to many subscribers. For some transports, when using large messages, the copy time can be the dominant factor. Note that when a message is actually shared, inproc will still perform an extra copy in order to ensure that it can modify the headers. This will unfortunately always be the case with REQ, as the REQ protocol keeps a copy of the original message so it can retry.
* fixes #1094 Consider in-lining task and aioGarrett D'Amore2020-01-08
| | | | | This only does it for rep, but it also has changes that should increase the overall test coverage for the REP protocol
* fixes #1104 move allocation of protocol objects to common coreGarrett D'Amore2020-01-03
| | | | fixes #1103 respondent could inline backtrace

* move all public headers to include/nng/ folderGregor Burger2018-11-22
| | | | | | | | | | This change makes embedding nng + nggpp (or other projects depending on nng) in cmake easier. The header files are moved to a separate include directory. This also makes installation of the headers easier, and allows clearer identification of private vs public heade files. Some additional cleanups were performed by @gedamore, but the main credit for this change belongs with @gregorburger.
* fixes #568 Want a single reader/write lock on socket child objectsGarrett D'Amore2018-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | fixes #170 Make more use of reaper This is a complete restructure/rethink of how child objects interact with the socket. (This also backs out #576 as it turns out not to be needed.) While 568 says reader/writer lock, for now we have settled for a single writer lock. Its likely that this is sufficient. Essentially we use the single socket lock to guard lists of the socket children. We also use deferred deletion in the idhash to facilitate teardown, which means endpoint closes are no longer synchronous. We use the reaper to clean up objects when the reference count drops to zero. We make a special exception for pipes, since they really are not reference counted by their parents, and they are leaf objects anyway. We believe this addresses the main outstanding race conditions in a much more correct and holistic way. Note that endpoint shutdown is a little tricky, as it makes use of atomic flags to guard against double entry, and against recursive lock entry. This is something that would be nice to make a bit more obvious, but what we have is safe, and the complexity is at least confined to one place.
* fixes #540 nni_ep_opttype serves no purposeGarrett D'Amore2018-06-13
| | | | | | | | | | | | fixes #538 setopt should have an explicit chkopt routine fixes #537 Internal TCP API needs better name separation fixes #524 Option types should be "typed" This is a rework of the option management code, to make it both clearer and to prepare for further work to break up endpoints. This reduces a certain amount of dead or redundant code, and actually saves cycles when setting options, as some loops were not terminated that should have been.
* 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 #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.
* 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.)
