* http: The big HTTP API refactoring of January 2025.v2.0.0-alpha.3http-client-transGarrett D'Amore2025-01-09
| | | | | | | | | | | | | | | | | | | | | | This represents a major change in the HTTP code base, consisting of a complete revamp of the HTTP API. The changes here are too numerous to mention, but the end result should be a vastly simpler API for both server and client applications. Many needless allocations were removed by providing fixed buffers for various parameters and headers when possible. A few bugs were fixed. Most especially we have fixed some bugs around very large URIs and headers, and we have also addressed conformance bugs to more closely conform to RFCs 9110 and 9112. As part of this work, the APIs for WebSockets changed slightly as well. In particular the properties available for accessing headers have changed. There is still documentation conversion work to do, and additional functionality (such as proper support for chunked transfers), but this is a big step in the right direction.
* platform: remove reader/writer locksGarrett D'Amore2025-01-05
| | | | | | The only thing using this was the transport lookups, but as those transports are now fully initialized in nng_init, we no longer need to lock that at all.
* Liberally apply some UWYI (use what you include) to header filesGarrett D'Amore2025-01-05
|
* args: Convert nng_opts_parse into a header only library using `nng_args_parse`.Garrett D'Amore2025-01-04
| | | | | | | | The API is identical, except that some names have changed, and this is now a header library in `nng/args.h` - so the core library does not need to carry this code in binaries. Being a header library also means it is not necessary to link against NNG, and it does not include any parts of NNG; it only depends on a standard C99 or C11 environment.
* tests: TLS transport test resilience against EADDRINUSEGarrett D'Amore2025-01-04
| | | | This was occasionally causing "sigabrt" and similar failures in the tests.
* api: fold TLS supplemental headers into nng.hGarrett D'Amore2025-01-04
|
* api: remove old protocol headersGarrett D'Amore2025-01-04
|
* api: rename nng_send_aio and nng_recv_aio to nng_socket_send and nng_socket_recvGarrett D'Amore2025-01-04
| | | | This aligns more closely with the nng_ctx functions.
* ipc: minor adjustments for ECLOSED and loggingGarrett D'Amore2025-01-03
|
* fixes #2061 Move IPC parameters from uint64 to intGarrett D'Amore2025-01-03
|
* api: Remove the NNG_FLAG_ALLOCGarrett D'Amore2025-01-01
| | | | | | | | This flag failed to provide real zero copy that it was intended for, and it also involved extra allocations. Further, the API for it was brittle and error prone. Modern code should just work directly with nng_msg structures.
* protocols: move content from the protocols to nng.hGarrett D'Amore2025-01-01
| | | | | This should simplify things for developers. Just one header to include in most cases now.
* socket: rename nng_close to nng_socket_closeGarrett D'Amore2024-12-31
|
* websocket tests: more resilience against EADDRINUSEGarrett D'Amore2024-12-31
|
* udp: use a bounce buffer if we lack sendmsg or recvmsgGarrett D'Amore2024-12-29
| | | | | This includes checks to determine if those functions are present, and a test case to verify that scatter gather with UDP works.
* resolver: use explicit resolver item provided by callerGarrett D'Amore2024-12-28
| | | | | | This avoids the need to perform multiple allocations for dialing, eliminating additional potential failures. Cancellation is also made simpler and more perfectly robust.
* zerotier: removedGarrett D'Amore2024-12-26
| | | | | | | | | | All vestiges of ZeroTier have been removed. Also, as consequence, some binary values have changed (specifically the number of the address family used for NNG_AF_ABSTRACT.) We may create a new ZeroTier transport that makes use of lwIP to provide for ZeroTier and native host network coexistence, without requiring ZeroTier to participate in the native networking stack.
* fix for potential leaking connectionsGarrett D'Amore2024-12-26
|
* pipeline: use nni_aio_startGarrett D'Amore2024-12-26
|
* sub: remove some calls to nni_aio_beginGarrett D'Amore2024-12-26
|
* pair0: use nni_aio_startGarrett D'Amore2024-12-26
|
* pair1: use nni_aio_startGarrett D'Amore2024-12-26
|
* pub sub: use nni_aio_startGarrett D'Amore2024-12-26
|
* bus: use nni_aio_startGarrett D'Amore2024-12-26
| | | | | | The test needed a change to ensure that we do not trigger a debugging check (you cannot submit another job on an aio that you've been notified is stopped via NNG_ESTOPPED.)
* req rep: use nni_aio_startGarrett D'Amore2024-12-26
|
* survey protocol conversion to nni_aio_startGarrett D'Amore2024-12-26
|
* udp: more nni_aio_startGarrett D'Amore2024-12-26
|
* tls: use nni_aio_beginGarrett D'Amore2024-12-26
|
* udp: use nni_aio_startGarrett D'Amore2024-12-26
| | | | | | This also moves the close of the UDP socket later, to avoid a potential use after free while the aio's are still in-flight. Unfortunately we cannot unbind cleanly without a hard close.
* ipc: use nni_aio_startGarrett D'Amore2024-12-26
|
* tcp: use nni_aio_startGarrett D'Amore2024-12-26
|
* websocket: use nni_aio_startGarrett D'Amore2024-12-26
|
* inproc: use nni_aio_startGarrett D'Amore2024-12-26
|
* sockfd: convert to use nni_aio_startGarrett D'Amore2024-12-26
|
* aio: introduce NNG_ESTOPPEDGarrett D'Amore2024-12-26
| | | | | | | | | | | This error code results when an AIO is stopped permanently, as a result of nni_aio_close or nni_aio_stop. The associated AIO object cannot be used again. This discrimantes against a file being closed, or a temporary cancellation which might allow the aio to be reused. Consumers must check for this error status in their callbacks, and not resubmit an operation that failed with this error. Doing so, will result in an infinite loop of submit / errors.
* aio: introduce nni_aio_deferGarrett D'Amore2024-12-22
| | | | | | | | This will replace nni_aio_schedule, and it includes finishing the task if needed. It does so without dropping the lock and so is more efficient and race free. This includes some conversion of some subsystems to it.
* test: fix valgrind complaint about unitialized test data in ipc testGarrett D'Amore2024-12-22
|
* websocket: stop trying to accept once we're closedGarrett D'Amore2024-12-16
|
* tls: fix deadlock in error pathGarrett D'Amore2024-12-16
|
* transports: all transports use the new inline approachGarrett D'Amore2024-12-15
| | | | | | We can retire the old approach that used separate allocations, and all of the supporting code. This also gives us a more natural signature for the end point initializations.
* websocket transport: use inline SP objectsGarrett D'Amore2024-12-15
| | | | | | | | | This also fixes a possible race in the listener that may cause connections to be dropped incorrectly, if the connection arrives before the common layer has posted an accept request. Instead we save the connection and potentially match later, like we do for the other protocols that need to negotiate.
* tls transport: use inline SP structuresGarrett D'Amore2024-12-15
|
* tls transport: inline aiosGarrett D'Amore2024-12-15
|
* inproc: use inline data structures for SP blocksGarrett D'Amore2024-12-15
| | | | | The pair is still a separate allocation, but this overall does reduce the number of allocations as well as a failure paths.
* inproc: use nni_refcntGarrett D'Amore2024-12-15
|
* test: fix uninitialized complaint from tcp recv max testGarrett D'Amore2024-12-15
|
* ipc: remove unnecessary check for null msg in finiGarrett D'Amore2024-12-15
|
* tcp transport: use preallocated SP objectsGarrett D'Amore2024-12-15
| | | | This follows a pattern we started earlier with IPC.
* tcp transport: inline aios (eliminate failure paths)Garrett D'Amore2024-12-15
|
* streams: add explicit stop functionsGarrett D'Amore2024-12-12
| | | | | | | | | | | | This allows us to explicitly stop streams, dialers, and listeners, before we start tearing down things. This hopefully will be useful in resolving use-after-free bugs in http, tls, and websockets. The new functions are not yet documented, but they are nng_stream_stop, nng_stream_dialer_stop, and nng_stream_listener_stop. They should be called after close, and before free. The close functions now close without blocking, but the stop function is allowed to block.
