* ipc: more robust initLiam Staskawicz2018-03-02

* 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.
* CMake & CPack improvements.Garrett D'Amore2018-02-21
| | | | | | | | | These are incremental updates... we avoid using install() in the subdirectories, so that we can adapt properly to them in the single parent directory. We have started some of the work to improve support for CPack. This is still not yet done, but work in progress.
* fixes #234 Investigate enabling more verbose compiler warningsGarrett D'Amore2018-02-14
| | | | | | | We enabled verbose compiler warnings, and found a lot of issues. Some of these were even real bugs. As a bonus, we actually save some initialization steps in the compat layer, and avoid passing some variables we don't need.
* 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 #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 #221 zerotier URL format changesGarrett D'Amore2018-01-22
| | | | | | We are adopting a more standard URL format for zerotier, and making more use of the URL parsing common layer. While here we updated the docs to reflect correctly the URI syntax we are using everywhere.
* fixes #219 transports should take URL structure instead of string addressGarrett D'Amore2018-01-22
| | | | | | | | | | This eliminates a bunch of redundant URL parsing, using the common URL logic we already have in place. While here I fixed a problem with the TLS and WSS test suites that was failing on older Ubuntu -- apparently older versions of mbedTLS were unhappy if selecting OPTIONAL verification without a validate certificate chain.

* fixes #209 NNG_OPT_TLS_VERIFIED is bustedGarrett D'Amore2018-01-17
| | | | | fixes #210 Want NNG_OPT_TLS_* options for TLS transport fixes #212 Eliminate a_endpt member of aio
* fixes #206 Want NNG_OPT_TLS_VERIFIED optionGarrett D'Amore2018-01-16
| | | | | | | | | | | | | | It is useful to have support for validating that a peer *was* verified, especially in the presence of optional validation. We have added a property that does this, NNG_OPT_TLS_VERIFIED. Further, all the old NNG_OPT_WSS_TLS_* property names have also been renamed to generic NNG_OPT_TLS property names, which have been moved to nng.h to facilitate reuse and sharing, with the comments moved and corrected as well. Finally, the man pages have been updated, with substantial improvements to the nng_ws man page in particular.
* 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.
* Refactored file API.Garrett D'Amore2018-01-11
| | | | | | | | | This refactor of the file API provides a simpler and easier to use interface for our needs (and simpler to implement) in both the ZeroTier transport and the HTTP/TLS file accesses. It also removes some restrictions present on the old one, although it is still not suitable for working with large files. (It will work, just be very inefficient as the entire file must be loaded into memory.)
* fixes #186 Suggested API changes for nng TLS certsGarrett D'Amore2018-01-09
|
* Convert existing websocket and http code to use new URL framework.Garrett D'Amore2018-01-05
| | | | | | This also fixes a use-after-free bug in the HTTP framework, where the handler could be deleted why callbacks were still using it. (We now reference count the handlers.)
* Fix some more leaks, add a generic URL parser.Garrett D'Amore2018-01-05
|
* Fix leaks on send.Garrett D'Amore2018-01-03
| | | | | | | I'm pretty sure I need to go back and review the handling of send messages for websocket too. We still have a receive leak in websocket and leaks caused by the new URL parsing code which needs to be refactored.
* Websocket subprotocol not sent or checked.Garrett D'Amore2018-01-02

* Fix HTTP sconn race, and compile bugs introduced.Garrett D'Amore2018-01-01

* 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 #160 Convert TLS url from tls:// to tls+tcp://Garrett D'Amore2017-11-27
|
* fixes #3 TLS transportGarrett D'Amore2017-11-20
| | | | | | | | | | | | | | | | | | | This introduces a new transport (compatible with the TLS transport from mangos), using TLS v1.2. To use the new transport, you must have the mbed TLS library available on your system (Xenial libmbedtls-dev). You can use version 2.x or newer -- 1.3.x and PolarSSL versions are not supported. You enable the TLS transport with -DNNG_TRANSPORT_TLS=ON in the CMake configuration. You must configure the server certificate by default, and this can only be done using nng options. See the nng_tls man page for details. This work is experimental, and was made possible by Capitar IT Group BV, and Staysail Systems, Inc.
* fixes #154 underlyng TCP & IPC transports should support partial recv/sendGarrett D'Amore2017-11-13
| | | | fixes #155 POSIX TCP & IPC could avoid a lot of context switches
* fixes #143 Protocols and transports should be "configurable"Garrett D'Amore2017-11-02
| | | | | | | | | | | | | | | | | | | | This makes all the protocols and transports optional. All of them except ZeroTier are enabled by default, but you can now disable them (remove from the build) with cmake options. The test suite is modified so that tests still run as much as they can, but skip over things caused by missing functionality from the library (due to configuration). Further, the constant definitions and prototypes for functions that are specific to transports or protocols are moved into appropriate headers, which should be included directly by applications wishing to use these. We have also added and improved documentation -- all of the transports are documented, and several more man pages for protocols have been added. (Req/Rep and Surveyor are still missing.)
* Various man page fixups, add inproc header.Garrett D'Amore2017-10-24
| | | | | | | We added nng_inproc man page, and a header with an explicit registration method for it. We also fixed up the markup on several other pages, and corrected the include statements for nng_zerotier.
* fixes #127 Bad format TCP address causes null pointer exceptionGarrett D'Amore2017-10-23
| | | | I've added some tests to validate this too.
* 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 #120 nng_sockaddr options initialized with garbage dataGarrett D'Amore2017-10-19
|
* fixes #110 Cancellation race in ZeroTierGarrett D'Amore2017-10-10
|
* fixes #92 Support ZT federations (moons)Garrett D'Amore2017-10-10
| | | | This also fixes a fence post error in the ephemeral state handling .
* New platform API for storage methods.Garrett D'Amore2017-10-09
| | | | | | | | | | | This includes converting the ZeroTier transport to use these. The new API supports file creation, retrieval, and deletion. It also supports directory methods for traversal, creation, and deletion. It also has a few methods to obtain well-known directories like $TMPDIR and $HOME. A rich test suite for this functionality is added as well.
* fixes #5 Address propertiesGarrett D'Amore2017-10-03
| | | | | | | | | Added TCP socket address properties on pipes. This adds the plumbing for the various platform specifics, and includes both v4 and v6 handling. We've included a TCPv6 test as well.
* 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.
* Add support for ZT sockaddr properties (pipe).Garrett D'Amore2017-09-30
| | | | Also add a generic property test function to trantest.
* fixes #93 ZT physicalMTU parameter vanishedGarrett D'Amore2017-09-28
| | | | | | | fixes #94 don't allocate ZT send frame on stack Note that due to some other bug (in ZeroTier itself?) this fails to function unless ZT was built with -DZT_DEBUG=1 on macOS.
* 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.)
* Add improved getopt functions, pass integers by value.Garrett D'Amore2017-09-22
|
* Allocate AIOs dynamically.Garrett D'Amore2017-09-22
| | | | | | | | | | | | | | We allocate AIO structures dynamically, so that we can use them abstractly in more places without inlining them. This will be used for the ZeroTier transport to allow us to create operations consisting of just the AIO. Furthermore, we provide accessors for some of the aio members, in the hopes that we will be able to wrap these for "safe" version of the AIO capability to export to applications, and to protocol and transport implementors. While here we cleaned up the protocol details to use consistently shorter names (no nni_ prefix for static symbols needed), and we also fixed a bug in the surveyor code.
* Introduce utility safe string handling functions.Garrett D'Amore2017-08-28
| | | | | | | | We have our versions of strdup, strlcat, and strlcpy. This means we can avoid using snprintf() in many cases (saving cycles), and we can get safer checks. We use the platform supplied versions of these if they exist (wrapping with nni_xxx versions.)
* Fix a few warnings and subtle test races.Garrett D'Amore2017-08-24
