* fixes #901 shorter option get/set functions for all typesJake Woltersdorf2019-04-07
| | | | | | | | | | | | - Renamed internal nng_*_getx/setx methods with "nni" prefix - Moved stream get/set option definition macros to options.h and added "NNI_" prefix - "_PTR" variant of get/set option definition macros is for when first arg is passed as pointer (`nng_stream *s` vs `nng_pipe s`) - New get/set option functions for `nng_socket` are `nng_socket_get_X` eschewing the previous `nng_getopt` pattern - Macro-fy legacy getopt/setopt and implement in terms of "new" API - nng_setopt* use "new" shorter API. Add missing uint64 set functions. - Shorter get/set option functions get own man page and old getopt/setopt link to them - Built with -DNNG_ENABLE_DOC=ON and part of central libnng index - Update copyright
* fixes #894 nng_pipe_notify could use nng_pipe_ev typedef instead of intJake Woltersdorf2019-02-24
| | | | - Update nng_pipe_notify manpage including copyright
* fixes #835 inproc should use new option APIGarrett D'Amore2018-12-31
| | | | | Some more changes to use nni_type instead of nni_opt_type are included as well.
* 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.
* Only free in nng_send() if we succeed.Lawrence Kesteloot2018-09-15
| | | | | | | Both the man page and the comment (in nng.h) of nng_send() say that the buffer is freed only if the function succeeds. The previous code always freed (if the flag was set). This change only frees if we succeed.
* fixes #4 Statistics supportGarrett D'Amore2018-09-03
| | | | | | | | | | | | | | | | This introduces new public APIs for obtaining statistics, and adds some generic stats for dialers, listeners, pipes, and sockets. Also added are stats for inproc and pairv1 protocol. The other protocols and transports will have stats added incrementally as time goes on. A simple test program, and man pages are provided for this. Start by looking at nng_stat(5). Statistics does have some impact, and they can be disabled by using the advanced NNG_ENABLE_STATS (setting it to OFF, it's ON by default) if you need to build a minimized configuration.
* fixes #691 Desire 16 and 64 bit message manipulatorsGarrett D'Amore2018-08-31
| | | | | | We use macros to generate message bodies for each of the various variants, reducing source code size (but not compiled size). The documentation is updated to indicate each of these variants.
* fixes #506 AIO "providers" need a way to call nni_aio_schedule.Garrett D'Amore2018-08-20
|
* fixes #522 Separate out the endpoint plumbingGarrett D'Amore2018-06-27
| | | | | | | | | | This separates the plumbing for endpoints into distinct dialer and listeners. Some of the transports could benefit from further separation, but we've done some rather larger separation e.g. for the websocket transport. IPC would be a good one to update later, when we start looking at exposing a more natural underlying API.
* Update for 1.0.0-beta.1v1.0.0-beta.1Garrett D'Amore2018-05-18
| | | | | | We've added a new macro, NNG_RELEASE_SUFFIX. If this is not empty, then the release should be considered a pre-release, with no specific stability guarantees.
* 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 #389 Need pipe notification callbacksGarrett D'Amore2018-05-03
| | | | | | | | This adds a new pipe event notification API (callbacks called on either pipe add or remove), including both tests and docs. Also supporting APIs to get the socket or endpoint associated with a pipe are included (tested and documented as well.)
* fixes #381 Want comparators for various typesGarrett D'Amore2018-05-01
|
* fixes #375 integer types are error proneGarrett D'Amore2018-04-26
| | | | | | | | | | | | | | This change converts the various integer types like nng_socket in the public API to opaque structures that are passed by value. Basically we just wrap the integer ID. This "hack" give us strong type checks by the compiler (yay!), at the expense of not being able to directly use these as numbers (so comparisions for example don't work, and neither does initialization to zero using the normal method. Comparison of disassembly output shows that at least with the optimizer enabled there is no difference in the compiler output between using a structure or an integral value.
* fixes #342 Want Surveyor/Respondent context supportGarrett D'Amore2018-04-24
| | | | | | | | | | | | | | | | fixes #360 core should nng_aio_begin before nng_aio_finish_error fixes #361 nng_send_aio should check for NULL message fixes #362 nni_msgq does not signal pollable on certain events This adds support for contexts for both sides of the surveyor pattern. Prior to this commit, the raw mode was completely broken, and there were numerous other bugs found and fixed. This integration includes *much* deeper validation of this pattern. Some changes to the core and other patterns have been made, where it was obvioius that we could make such improvements. (The obviousness stemming from the fact that RESPONDENT in particular is very closely derived from REP.)
* fixes #363 context option plumbing missingGarrett D'Amore2018-04-24
|
* fixes #334 Separate context for state machines from socketsGarrett D'Amore2018-04-10
| | | | | | | | | | | | | | | This provides context support for REQ and REP sockets. More discussion around this is in the issue itself. Optionally we would like to extend this to the surveyor pattern. Note that we specifically do not support pollable descriptors for non-default contexts, and the results of using file descriptors for polling (NNG_OPT_SENDFD and NNG_OPT_RECVFD) is undefined. In the future, it might be nice to figure out how to factor in optional use of a message queue for users who want more buffering, but we think there is little need for this with cooked mode.
* 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 issues found by (and submitted by) @nonnenmacher when workingVincent Nonnenmacher2018-03-19
| | | | | | | on a python wrapper (cffi). Mostly this is fixing inconsistencies in our public API and the actual implementation.
* 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 #281 desire nng_sleep_aio()Garrett D'Amore2018-03-12
|
* fixes #254 nngcat should have a --version optionGarrett D'Amore2018-03-02
| | | | | | We only add a basic --version (also -V). I'm still trying to figure out how to convince cmake to emit its compilation flags into a file where we can use them for output.
* Remove some dead code.Garrett D'Amore2018-03-02

* fixes #240 nngcat is MIAGarrett D'Amore2018-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is intended to provide compatibility with, and has been tested against, legacy nanocat. There are a few differences though. At this time support for the alias names (where argv[0] is set to something like nngreq or somesuch) is missing. By default this library operations without NNG_FLAG_NONBLOCK on dial and listen, so that failures here are immediately diagnosable. (This behavior can be changed with the --async flag.) By default --pair means PAIRv1, but you can specify --pair0 or --pair1 explicitly. (There is also a --compat mode, and in that mode --pair means PAIRv0. The --compat mode also turns on NNG_FLAG_NONBLOCK by default.) The "quoted" mode also quotes tabs. (Legacy nanocat did not.) It is possible to connect to *multiple* peers by using the --dial or --listen (or similar) options multiple times. Shorthands can be used for long options that are not ambiguous. For example, --surv can be used to mean surveyor, but --re is invalid because it can mean req, rep, or respondent. We assume you have a reasonable standard C environment. This won't work in embedded environments without support for FILE *. TLS options are missing but to be added soon. A man page is still to be written.
* Modularize HTTP headers somewhat.Garrett D'Amore2018-02-21
| | | | | | We move the HTTP definitions out of the core nng.h and into a supplemental header. Most of this change was trivial updates to all of the HTTP related manual pages.
* Introduce 'porting layer' Public API.Garrett D'Amore2018-02-20
| | | | | | | This introduces portable primitives for time, random numbers, synchronization primitives, and threading. These are somewhat primitive (least common denominiators), but they can help with writing portable applications, especially our own demo apps.
* fixes #171 Refactor aio to use generic data fieldsGarrett D'Amore2018-02-08
| | | | | | | | This addresses the use of the pipe special field, and eliminates it. The message APIs (recvmsg, sendmsg) need to be updated as well still, but I want to handle that as part of a separate issue. While here we fixed various compiler warnings, etc.

* fixes #228 aio iov should have larger limits (dynamically allocated)Garrett D'Amore2018-02-05
|
* fixes #174 Define public HTTP client APIGarrett D'Amore2018-02-01
|
* 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.
* Expose scatter/gather I/O vectors; we will use for HTTP API.Garrett D'Amore2018-01-29

* fixes #222 Public URL APIGarrett D'Amore2018-01-23

* fixes #201 TLS configuration should support files for certificates and keysGarrett D'Amore2018-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | This adds support for configuration of TLS websockets using the files for keys, certificates, and CRLs. Significant changes to the websocket, TLS, and HTTP layers were made here. We now expect TLS configuration to be tied to the HTTP layer, and the HTTP code creates default configuration objects based on the URL supplied. (HTTP dialers and listeners are now created with a URL rather than a sockaddr, giving them access to the scheme as well.) We fixed several bugs affecting TLS validation, and added a test suite that confirms that validation works as it should. We also fixed an orphaned socket during HTTP negotiation, responsible for an occasional assertion error if the http handshake does not complete successfully. Finally several use-after-free races were closed. TLS layer changes include reporting of handshake failures using newly created "standard" error codes for peer authentication and cryptographic failures. The use of the '*' wild card in URLs at bind time is no longer supported for websocket at least. Documentation updates for all this are in place as well.
* fixes #166 Websocket TLS mappingGarrett D'Amore2017-12-30
| | | | | | | | | | | | | | | | | This introduces the wss:// scheme, which is available and works like the ws:// scheme if TLS is enabled in the library. The library modularization is refactored somewhat, to make it easier to use. There is now a single NNG_ENABLE_TLS that enables TLS support under the hood. This also adds a new option for the TLS transport, NNG_OPT_TLS_CONFIG (and a similar one for WSS, NNG_OPT_TLS_WSS_CONFIG) that offer access to the underlying TLS configuration object, which now has a public API to go with it as well. Note that it is also possible to use pure HTTPS using the *private* API, which will be exposed in a public form soon.
* fixes #2 Websocket transportGarrett D'Amore2017-12-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a rather large changeset -- it fundamentally adds websocket transport, but as part of this changeset we added a generic framework for both HTTP and websocket. We also made some supporting changes to the core, such as changing the way timeouts work for AIOs and adding additional state keeping for AIOs, and adding a common framework for deferred finalization (to avoid certain kinds of circular deadlocks during resource cleanup). We also invented a new initialization framework so that we can avoid wiring in knowledge about them into the master initialization framework. The HTTP framework is not yet complete, but it is good enough for simple static serving and building additional services on top of -- including websocket. We expect both websocket and HTTP support to evolve considerably, and so these are not part of the public API yet. Property support for the websocket transport (in particular address properties) is still missing, as is support for TLS. The websocket transport here is a bit more robust than the original nanomsg implementation, as it supports multiple sockets listening at the same port sharing the same HTTP server instance, discriminating between them based on URI (and possibly the virtual host). Websocket is enabled by default at present, and work to conditionalize HTTP and websocket further (to minimize bloat) is still pending.
* fixes #137 Remove public access to numeric protocolsGarrett D'Amore2017-10-31
|
* fixes #136 consider eliminating nng_shutdownGarrett D'Amore2017-10-30
|
* fixes #46 make device() use aios directlyGarrett D'Amore2017-10-26
| | | | | | | | | | This eliminates the separate threads used for devices, letting them benefit from the new aio framework. It also eliminates the legacy nni_sock_sendmsg and nni_sock_recvmsg internal APIs. It would appear that there is an opportunity here to provide asynchronous device support out to userland as well, exposing an aio to them. That work is deferred to later.
* fixes #45 expose aio to applicationsGarrett D'Amore2017-10-25
| | | | | | | | | | While here we added a test for the aio stuff, and cleaned up some dead code for the old fd notifications. There were a few improvements to shorten & clean code elsewhere, such as short-circuiting task wait when the task has no callback. The legacy sendmsg() and recvmsg() APIs are still in the socket core until we convert the device code to use the aios.
* fixes #132 Implement saner notification for file descriptorsGarrett D'Amore2017-10-24
| | | | | | | | | This eliminates the "quasi-functional" notify API altogether. The aio framework will be coming soon to replace it. As a bonus, apps (legacy apps) that use the notification FDs will see improved performance, since we don't have to context switch to give them a notification.
* Eliminate stale nng_clock function.Garrett D'Amore2017-10-19
|
* fixes #84 Consider using msec for durationsGarrett D'Amore2017-10-19
| | | | | | There is now a public nng_duration type. We have also updated the zerotier work to work with the signed int64_t's that the latst ZeroTier dev branch is using.
* fixes #116 Add missing ::nng_pipe_getopt_usec implementationGarrett D'Amore2017-10-18
|
* Added more complete tests, and changes to property handling.Garrett D'Amore2017-10-02
| | | | | | | | | | | | | | | | We allow some properties to be set on endpoints after they are started; transports now responsible for checking that. (The new values will only apply to new connections of course!) We added short-hand functions for pipe properties, and also added uint64_t shorthands across the board. The zerotier documentation got some updates (corrections). We have also added a separate header now for the ZT stuff. Also, dialers and listeners do not intermix anymore -- we test that only a dialer can be used with setting dialer options, and likewise for listeners.
* Remove last vestiges of integer option numbers.Garrett D'Amore2017-09-27
|
* Refactor option handling APIs.Garrett D'Amore2017-09-27
| | | | | | | | | | | | This makes the APIs use string keys, and largely eliminates the use of integer option IDs altogether. The underlying registration for options is also now a bit richer, letting protcols and transports declare the actual options they use, rather than calling down into each entry point carte blanche and relying on ENOTSUP. This code may not be as fast as the integers was, but it is more intuitive, easier to extend, and is not on any hot code paths. (If you're diddling options on a hot code path you're doing something wrong.)
* ZeroTier transport implementation (work funded by Capitar IT Group BV)Garrett D'Amore2017-09-26
| | | | | | | | | | | | | The ZeroTier transport is experimental at this point, and not enabled by default. It does not work with Windows yet (the Windows platform needs UDP support first.) Configure with -DNNG_ENABLE_ZEROTIER=yes -DNNG_ZEROTIER_SOUCE=<path> The <path> must point to a dev branch of the ZeroTierOne source tree, checked out, and built with a libzerotiercore.a in the top directory, and a ZeroTierOne.h header located at include. The build will add -lc++ to the compile, as the ZeroTier core functionality is written in C++ and needs some runtime support (e.g. new, delete, etc.)
* More pipe option handling, pipe API support. Url option.Garrett D'Amore2017-09-22
| | | | | | | | | | This fleshes most of the pipe API out, making it available to end user code. It also adds a URL option that is independent of the address options (which would be sockaddrs.) Also, we are now setting the pipe for req/rep. The other protocols need to have the same logic added to set the receive pipe on the message. (Pair is already done.)
