* api: introduce NNG 2.0 compatible nng_dialer_get_url and nng_listener_get_urlGarrett D'Amore2025-01-04
| | | | This is meant to help applications start adopting new interfaces before converting to NNG 2.0
* api: add nng_sock_send and nng_sock_recvGarrett D'Amore2025-01-04
| | | | | | These are the 2.0 equivalent versions of nng_send_aio and nng_recv_aio. The old names are preserved as aliases for the new. Applications can start adopting these with this release, even before 2.0 is ready.
* stable: add nng_socket_close to aid transition to 2.0Garrett D'Amore2025-01-03
|
* Add new functions for socket identity.Garrett D'Amore2024-11-11
| | | | | | | | | | These functions were added in the main branch for NNG 2.0, and we add them here to facilitate converting any code that happened to use the options (`NNG_OPT_PROTO`, `NNG_OPT_PROTONAME`, `NNG_OPT_PEER`, `NNG_OPT_PEERNAME`, and `NNG_OPT_RAW`. Its unlikely that many applications need this, but providing these as a transition aid may help applications start adopting new APIs now.
* Mark some functions that are useless as deprecatedGarrett D'Amore2024-11-07
|
* UDP: Introduce an experimental (undocumented for now) public API for UDP. ↵Garrett D'Amore2024-06-02
| | | | | | | | (#1838) This exposes the UDP methods as nng_ methods, and adds support for Multicast Membership, which is useful in a variety of situations. No documentation is provided, and applications should consider thios API experimental.
* Move the rest of the functionality from platform.h into core.Garrett D'Amore2024-04-23
| | | | This also deprecates supplemental/util/platform.h.
* fixes #1572 nng creates too many threadsGarrett D'Amore2024-01-01
| | | | | | | | | | | | This further limits some of the thread counts, but principally it offers a new runtime facility, nng_init_set_parameter(), which can be used to set certain runtime parameters on the number of threads, provided it is called before the rest of application start up. This facility is quite intentionally "undocumented", at least for now, as we want to limit our commitment to it. Still this should be helpful for applications that need to reduce the number of threads that are created.
* fixes #1751 Support nng_aio_set_expire().Garrett D'Amore2023-12-30
| | | | While here fixed a number of nits in comments.
* fixes #1574 Non-blocking version of nng_aio_wait / nng_aio_resultGarrett D'Amore2022-04-18
| | | | | | | This introduces a new API, nng_aio_busy(), that can be used to query the status of the aio without blocking. Some minor documentation fixes are included.
* Introduce nng_device_aio().Garrett D'Amore2021-12-27
| | | | | | This function is like nng_device(), but runs asynchronously. Also, this fixes #1503 nng_device causes nng_close to blocking
* Fix incorrect elides of deprecated code.Garrett D'Amore2021-11-29
| | | | | | (Note that this includes some incorrect formatting due to an apparent bug in clang-format 13. Hopefully they'll fix it later, but for now I'm preserving the bad whitespace.)
* fixes #1536 nng_sendmsg and nng_recvmsg could be fasterGarrett D'Amore2021-11-28
| | | | fixes #1535 Desire nng_ctx_sendmsg and nng_ctx_recvmsg
* fixes #1498 Endpoint close/shutdown could be synchronous (#1499)Garrett D'Amore2021-09-04
|
* Add & document msg_capacity, msg_reserve (#1458)Evan Balster2021-07-06
| | | | | | | * Add & document msg_capacity, msg_reserve * reserve/capacity code style * Documentation references to reserve/capacity
* fixes #1313 support deferred nng_aio destructionGarrett D'Amore2020-12-12
|
* fixes #1365 nng_recvmsg returns NNG_ETIMEDOUT rather than NNG_EAGAINGarrett D'Amore2020-12-05
|
* fixes #1071 tran_chkopt can be cleaned upGarrett D'Amore2020-11-15
| | | | | | | | | | | | | | | | | This is a sweeping cleanup of the transport logic around options, and also harmonizes the names used when setting or getting options. Additionally, legacy methods are now moved into a separate file and can be elided via CMake or a preprocessor define. Fundamentally, the ability to set to transport options via the socket is deprecated; there are numerous problems with this and my earlier approaches to deal with this have been somewhat misguided. Further these approaches will not work with future protocol work that is planned (were some options need to be negotiated with peers at the time of connection establishment.) Documentation has been updated to reflect this. The test suites still make rather broad use of the older APIs, and will be converted later.
* 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 #1201 Unexpected error return code: NNG_ENOMEMGarrett D'Amore2020-02-25
|
* fixes #1145 nng_msg options should be removedGarrett D'Amore2020-01-19
|
* RESPOND needs to use atomic for TTL.Garrett D'Amore2020-01-16
| | | | | Also, add a test to cover the RESPOND protocol. This gets about 95% of the coverage.
* 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
* Add error message for NNG_ECONNSHUT (#1084)Robert Bielik2020-01-01
| | | | | | * Add error message for NNG_ECONNSHUT * Added missing space after string.
* 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.
