* fixes #1808 nng_msg_insert: munmap_chunk(): invalid pointerGarrett D'Amore2024-04-24
| | | | | | | With specific message sizes, we the shuffle of data for msg insert can calculate the wrong value, leading to heap corruption. This includes a stress test for msg insert to hopefully exercise every reasonable edge case.
* Move the rest of the functionality from platform.h into core.Garrett D'Amore2024-04-23
| | | | This also deprecates supplemental/util/platform.h.
* Logging improvements (#1816)Garrett D'Amore2024-04-21
| | | | | | | | | | | | * Add nng_str_sockaddr to get string representation of socket address. * Added nng_log_get_level() is meant to allow users to obtain the current level and avoid some possibly expensive operations just to collect debugging information when debugging is not in effect. We use a custom logger for NUTS, and this fits within the NUTS test framework well, so that if -v is supplied we get more content. All tests now get this by default.
* Log messages when peer sends too large message.Garrett D'Amore2024-04-17
| | | | | Also while here, remove unused sockaddr members from some structs. This should save a bit of memory for servers with a lot of conns.
* [tls_common] finish conn lock in tls_reapMoi Ran2024-04-14
|
* fixes #1588 TLS should log errorsGarrett D'Amore2024-04-14
| | | | | This isn't complete, but it should go much further in assisting debugging TLS related errors.
* Announce NNG version in log.Garrett D'Amore2024-04-14
|
* Log rejects by app, bind/listen/connect failures.Garrett D'Amore2024-04-14
|
* Log protocol connections rejected by protocol.Garrett D'Amore2024-04-14
|
* Log transports as they are initialized.Garrett D'Amore2024-04-14
|
* Added realtime clock support, and better timestamping.Garrett D'Amore2024-04-14
| | | | | The realtime clock is not (yet) exposed for user applications, but it is used for logging timestamps accurately.
* minor include fixGarrett D'Amore2024-04-14
|
* Add missing `nng_tls_config_hold` stub functionMarc Lasch2024-04-13
| | | | | | | | | | | Add the missing stub function implementation for `nng_tls_config_hold`. Fixes an error when loading the library and expecting to have this symbol available. The availability of the symbol can be checked with nm: ``` nm -D cmake-build-release/libnng.so.1.7.3 | grep nng_tls_config_hold ```
* add header to posix_rand_getrandom.cshikokuchuo2024-04-13
|
* fixes #543 Add logging support frameworkGarrett D'Amore2024-04-13
|
* Update protocol.hBrian Carcich2024-03-16
| | | Fix comment typo
* fixes #1771 cmake: respect CMAKE_FIND_PACKAGE_PREFER_CONFIG if presentGarrett D'Amore2024-02-28
|
* Convert UDP platform test to NUTS.Garrett D'Amore2024-02-25
| | | | | | This also restores the IPv6 sanity check. Note that UDP is still not supported as a transport, but this can be used to implement higher level transports such as ZeroTier (or later QUIC).
* windows: marry - warning about HANDLE vs intGarrett D'Amore2024-02-25
|
* fixes #1496 Provide NNG_ENABLE_IPV6 option (disabled by default)Garrett D'Amore2024-02-25
| | | | | | | | | This also checks if the build system has the definitions for AF_INET6, which might help in some embedded IPv4 only settings. The resolver test is enhanced to include a check for IPv6 enabled in the kernel. IPv6 support is enabled by default, of course.
* fixes #1543 Deadlock in nng_close(socket)Garrett D'Amore2024-02-25
| | | | | | This looks like a possible problem that may be windows specific involving the flow for IO completion ports. This simplifies the logic a little bit, and should ensure that canceled requests on pipes do not restart.
* windows: Add missing header for string.hGarrett D'Amore2024-02-25
|
* Add support for socket:// in NUTS marry function.Garrett D'Amore2024-02-18
| | | | | This also adds a HUGE test for REP using socket so that we can discriminate failures that might exist using sockets instead of inproc.
* Add REP huge reply (10MB) testGarrett D'Amore2024-02-18
|
* fix typo in test for CMAKE_FIND_PACKAGE_PREFER_CONFIGGarrett D'Amore2024-02-17
|
* Windows: Use _close instead of closeGarrett D'Amore2024-01-27
|
* base64_test: fix compiler warning about castGarrett D'Amore2024-01-27
|
* tls: fix cast to integer warningGarrett D'Amore2024-01-27
|
* Mbed TLS CMake improvements.Garrett D'Amore2024-01-27
| | | | | Try to use the Mbed TLS cmake configuration data if present, and refactor our FindModule to adhere to the same basic API.
* New CMAKE option NNG_ENABLE_COMPAT (defaults ON)Garrett D'Amore2024-01-27
| | | | | | This option allows the compatibility code to be elided from the build. This saves build time, and eliminates bloat from a static library when used strictly in native NNG mode.
* Fix warning from inconsistent socket_pair prototype.Garrett D'Amore2024-01-06
|
* fix idhash not publicGarrett D'Amore2024-01-06
| | | | | | | | | We accidentally made idhash not public by not publishing its header in the right place. This is really generic utility stuff, so we have posted it in the nng/supplemental/util/ directory. We've also removed the ability to remove this -- its a very small amount of additional code, as its just a wrapper on top of mandatory functionality.
* silence compiler warning from minimum int constantGarrett D'Amore2024-01-01
|
* 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.
* Comment typoGarrett D'Amore2024-01-01
|
* fixes #1751 Support nng_aio_set_expire().Garrett D'Amore2023-12-30
| | | | While here fixed a number of nits in comments.
* provide NNG_MAX_POLLER_THREADSGarrett D'Amore2023-12-29
| | | | | | | This (defaults to 8) sets a limit on the number of poller threads that will be used for servicing I/Os. This is the size of the I/O completion port thread pool on Windows. POSIX pollers are generally not concurrent at present.
* fixes #1740 Public ID hash APIGarrett D'Amore2023-12-29
| | | | | | | | | This includes a manual page documenting the entire set of functions in one step. The hash is 64-bit based for now, to be maximally flexible. An internal 32-bit convenience for the common internal use is also provided (not public). The public API includes a test suite.
* tcp and tls: setting recv max on endpoint does not change pipesGarrett D'Amore2023-12-29
| | | | | Again, this was racy code, and not well tested. Set this option before starting the endpoint if you need to be sure.
* ipc: changing ep receive max should not affect established pipesGarrett D'Amore2023-12-29
| | | | This code was not well tested, and is racy as well.
* ipc: refactor get peerid support to use common POSIX codeGarrett D'Amore2023-12-29
| | | | | This eliminates some code. A test is added as well, so this should help with coverage.
* fixes #1746 Create a new socket:// transport for socketpair() based connectionsGarrett D'Amore2023-12-29
| | | | | | | | | | | | | This transport only listens, and creates connections when the application calls setopt on the lister with NNG_OPT_SOCKET_FD, to pass a file descriptor. The FD is turned into an nng_stream, and utilized for SP. The protocol over the descriptor is identical to the TCP protocol (not the IPC protocol). The options for peer information are borrowed from the IPC transport, as they may be useful for these purposes. This includes a test suite and full documentation.
* fixes #1734 websocket dialer hang on shutdownGarrett D'Amore2023-12-17
| | | | | | It's not absolutely clear that this fixes all of the possible cases, but we're hopeful that this does -- and in any event the bug does not seem to reproduce easily anymore.
* fixes #1735 websocket should send, and wait for, WS_CLOSE frames on shutdownGarrett D'Amore2023-12-17
| | | | fixes #1733 deadlock in websocket listener close
* fixes #1729 remove nni_timerGarrett D'Amore2023-12-17
|
* fixes #1728 surveyor could be simplified to not use timerGarrett D'Amore2023-12-17
|
* minor comment fixes for survey_testGarrett D'Amore2023-12-17
|
* fixes #1663 Request/Reply Protocol Throughput and ScalabilityGarrett D'Amore2023-12-16
| | | | | | | | | | | | | | | This eliminates the req protocols use of nni_timer (and setting a single timer node per request. This was problematic because it devolves into O(n^2) as we wind up inserting timer nodes and having to scan the list for the timer node. The solution is to use a single scan - stop worrying about insertion, but instead use a coarse granularity timer (defaults to 1 second) for retries. Then do the O(n) scan just once per interval. A new option, NNG_OPT_REQ_RESENDTICK, can be used to change the tick interval for cases (like unit tests) where more fine grained timing is required.
* fixes #1673 High CPU usage with TLSGarrett D'Amore2023-12-16
| | | | | | The aio for connections was meant to have an infinite sleep (no timeout), but was getting an initial value of zero, so we were spinning on accept.
* fixes #1713 SP pipe_send leaks message if aio is canceledGarrett D'Amore2023-11-26
