* fixes #1345 Restructure the source treeGarrett D'Amore2021-01-01
| | | | | This is not quite complete, but it sets the stage for other protocols (such as zmq or mqtt) to be added to the project.
* New NUTS test framework (NNG Unit Test Support).Garrett D'Amore2020-11-23
| | | | | | | | | | | | | This is based on testutil/acutest, but is cleaner and fixes some short-comings. We will be adding more support for additional common paradigms to better facilitate transport tests. While here we added some more test cases, and fixed a possible symbol collision in the the stats framework (due to Linux use of a macro definition of "si_value" in a standard OS header). Test coverage may regress slightly as we are no longer using some of the legacy APIs.
* Work for test refactoring.Garrett D'Amore2020-11-18
| | | | | | | | | | | | | | | | | | | | | | There are a few major areas in this change. * CMake options are now located in a common cmake/NNGOptions.cmake file. This should make it easier for folks to figure out what the options are, and how they are used. * Tests are now scoped with their directory name, which should avoid possible name collisions with test names. * A number of tests have been either moved or incorporated into the newer testutil/acutest framework. We are moving away from my old c-convey framework to something easier to debug. * We use CMake directories a bit more extensively leading to a much cleaner CMake structure. It's not complete, but a big step in the right direction, and a preview of future work. * Tests are now run with verbose flags, so we get more test results in the CI/CD logs.
* 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 #1087 CMakeLists structural improvements desiredGarrett D'Amore2020-11-14
| | | | | This doesn't modularize all the tests yet, but it goes a long way in the right direction.
* fixes #1041 Abstract socket address for IPCGarrett D'Amore2020-11-08
| | | | | | | | | | | | | | | | | | | | | | | | fixes #1326 Linux IPC could use fchmod fixes #1327 getsockname on ipc may not work This introduces an abstract:// style transport, which on Linux results in using the abstract socket with the given name (not including the leading NULL byte). A new NNG_AF_ABSTRACT is provided. Auto bind abstract sockets are also supported. While here we have inlined the aios for the POSIX ipc pipe objects, eliminating at least one set of failure paths, and have also performed various other cleanups. A unix:// alias is available on POSIX systems, which acts just like ipc:// (and is fact just an alias). This is supplied so that in the future we can add support for AF_UNIX on Windows. We've also absorbed the ipcperms test into the new ipc_test suite. Finally we are now enforcing that IPC path names on Windows are not over the maximum size, rather than just silently truncating them.
* fixes #960 NNG threads inherit application thread nameGarrett D'Amore2020-08-08
| | | | | | This also exposes an nng_thread_set_name() function for applications to use. All NNG thread names start with "nng:". Note that support is highly dependent on the operating system.
* fixes #1275 Test timeouts on FreeBSDGarrett D'Amore2020-08-08
| | | | | | | | | | This was responsible for hangs in close on FreeBSD. Apparently our use of EVFILT_USER was incorrect, and rather than fix it, we have switched to using a notification pipe for synchronizing closing pipes. In addition to fixing this problem, it should significantly improve things for NetBSD and OpenBSD, which will now be able tbenefit from kqueue(), since we no longer depend on EVFILT_USER.
* Prefix all tests with PROJECT_NAME (#1276)Hugo Lindström2020-08-07
|
* fixes #1232 EVFILT_USER is not available on NetBSDGarrett D'Amore2020-07-26
| | | | | | This means that NetBSD and OpenBSD cannot benefit from kqueue, and will need to use poll(). The best answer for those platforms is that someone contribute a working EVFILT_USER implementation.
* Print NNG configuring message to STATUS mode.Indy2020-07-06
| | | | The default mode under default configration prints to stderr, some build tools take this to mean an error has occured incorrectlly.

* fixes #1202 More than 120 threads was started by NNGGarrett D'Amore2020-02-24
| | | | | | | | This introduces a new CMake option, NNG_MAX_TASKQ_THREADS, with a default value of 16. The number of taskq workers will generally be calculated as vcpu * 2. This new value, if not zero, sets an upper bound. Note that the value should be at least two, in order to ensure no deadlocks occur.
* fixes #1005 TLS 1.3 supportGarrett D'Amore2020-02-23
| | | | | | | | This introduces support for an external wolfSSL plugin, and generally creates the framework for pluggable TLS implementations. The wolfSSL engine is provided via an external module (git submodule), available either under a GPLv3 license or a commercial license.

| | | | | | This increases the minor version to 1.3.0. This is not yet an official release, so you can't rely on it, and we will probably add more API features before we finalize 1.3.0.

* fixes #1032 Figure out Darwin bustednessGarrett D'Amore2019-12-24
| | | | | | | | | | | | | | | | | | | | | | | | fixes #1035 Convey is awkward -- consider acutest.h This represents a rather large effort towards cleaning up our testing and optional configuration infrastructure. A separate test library is built by default, which is static, and includes some useful utilities design to make it easier to write shorter and more robust (not timing dependent) tests. This also means that we can cover pretty nearly all the tests (protocols etc.) in every case, even if the shipped image will be minimized. Subsystems which are optional can now use a few new macros to configure what they need see nng_sources_if, nng_headers_if, and nng_defines_if. This goes a long way to making the distributed CMakefiles a lot simpler. Additionally, tests for different parts of the tree can now be located outside of the tests/ tree, so that they can be placed next to the code that they are testing. Beyond the enabling work, the work has only begun, but these changes have resolved the most often failing tests for Darwin in the cloud.

* fixes #577 target library dependencies should be publicGarrett D'Amore2018-11-05
| | | | | | | | | | | This is a significant refactor of the library configuration. We use the modern package configuration helper, with a template script that also does the find_package dance for any of our dependencies. We also have restructured the code so that most protocols and transports have their configuration isolated to their own CMakeLists file, reducing the size of the global CMakeLists file.

* fixes #735 Configuring ZeroTier for a unified build is too hardGarrett D'Amore2018-09-24
| | | | | | | This changes the code to make use of a different project we have created (libzerotiercore) that is "CMake clean". This should make using and configuring this code *much* better. It may also have the benefit of making this configuration work better for Windows systems.
* 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 #572 Several locking errors foundGarrett D'Amore2018-07-03
| | | | | | | | | | fixes #573 atomic flags could help This introduces a new atomic flag, and reduces some of the global locking. The lock refactoring work is not yet complete, but this is a positive step forward, and should help with certain things. While here we also fixed a compile warning due to incorrect types.
* fixes #496 nngcat tests fail in Xcode buildGarrett D'Amore2018-06-01
| | | | | | | | | | | | This avoids copying the tests, but runs them with bash from the source directory, and passes the path to the built nngcat binary to the script. It also permits these to run if we find bash, so that systems without bash won't run it and fail. We still only do this on POSIX though, because Windows bash is too broken to use for some of the tests.
* fixes #477 Android NDK build configurationGarrett D'Amore2018-05-30
| | | | | | | | | | | | This enables the software to be built for Android, going back to at least Android SDK r15 (IceCreamSandwich) and at least up to SDK r27 (Oreo). Older versions of Android may work, but we have no way to build them to test. While here we have changed our CMake configuration to disable building tools or tests when we detect a cross-compile situation. Documentation for cross-compilation is updated as well.
* fixes #484 crashes in websocket transportGarrett D'Amore2018-05-29
| | | | | | | | | | | | | | | | | | | | | | | fixes #490 posix_epdesc use-after-free bug fixes #489 Sanitizer based testing would help fixes #492 Numerous memory leaks found with sanitizer This introduces support for compiler-based sanitizers when using clang or gcc (and not on Windows). See NNG_SANITIZER for possible settings such as "thread" or "address". Furthermore, we have fixed the issues we found with both the thread and address sanitizers. We believe that the thread issues pointed to a low frequency use-after-free responsible for rare crashes in some of the tests. The tests generally have their timeouts doubled when running under a sanitizer, to account for the extra long times that the sanitizer can cause these to take. While here, we also changed the compat_ws test to avoid a particularly painful and time consuming DNS lookup, and we made the nngcat_unlimited test a bit more robust by waiting before sending traffic.
* fixes #486 Revisit SOVERSION and VERSIONGarrett D'Amore2018-05-25
| | | | | | | | | | | | | | | | | | | | | | fixes #485 Honor BUILD_SHARED_LIBS fixes #483 Don't expose private symbols in shared library fixes #481 Export CMake target This is a "large" commit involving changes that don't affect the code directly, but which have an impact on how we package and build our project. The most significant of these changes is that we now build only either a shared or a static library, depending on the setting of the BUILD_SHARED_LIBS option. We also suppress private symbols from being exposed when the underlying toolchain lets us do so. Minor updates to the way we version the ABI are used, and we now have a nice exported CMake project. To import this project in another, simply do find_package(nng) and you can add target_link_libraries(nng::nng) to your targets. CMake does the rest for you.
