* Document HTTP request/reply structures and handling.Garrett D'Amore2018-02-02

* Add, and document, the url->u_requri member.Garrett D'Amore2018-02-02
| | | | | This member is the value passed in actual HTTP protocol, so it is useful with the function nng_http_req_set_uri().
* fixes #174 Define public HTTP client APIGarrett D'Amore2018-02-01
|
* 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.

* Add message handling man pages.Garrett D'Amore2018-01-23
| | | | | | Note that we're also no longer overriding the source formatter or the icons for new pages, since we can supply that on the command line in the script that generates output.

* Better PDF output to work around limitations in asciidoctor.Garrett D'Amore2018-01-23

* Updates to support generation of PDF (pretty) and PostScript (ugly).Garrett D'Amore2018-01-23
| | | | | The preview script also changes to take a "-s <style>" argument instead of single flag switches.
* 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 #217 URL canonicalization needs workGarrett D'Amore2018-01-21

* fixes #216 HTTP server side API refactoring, directory serving supportGarrett D'Amore2018-01-20
| | | | | | | | | | | This changes the backend (internal) HTTP API to provide a much more sensible handler scheme, where the handlers are opaque objects and we can allocate a handler for different types of tasks. We've also added support serving up directories of static content, and added code to validate that the directory serving is working as intended. This is a key enabling step towards the public API.

* 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.)

* Fix possible use-after-free reaping things using random.Garrett D'Amore2018-01-05
|
* 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.
* Fix websocket hang after sending one message.Garrett D'Amore2018-01-03
| | | | | | | | | | | | | This fixes a problem where the websocket would only send one message, then no others, due to not clearing the "frame" busy flag on completion of the frame transmit. We have also added a test that tries to send 10 messages back and forth to make sure that we catch this kind of problem in the future. Finally we've fixed some problems that were found when testing edge cases around the protocol, which were responsible for invalid memory accesses.
* Do not free the request structure on error -- the http server needs it.Garrett D'Amore2018-01-03

* Don't hold the lock while stopping HTTP!Garrett D'Amore2018-01-02

* fixes #191 Several HTTP problems foundGarrett D'Amore2018-01-02
| | | | | | | | | | | | | | | | First, httpbin.org was having some high latency (load) earlier today, so we needed to bump the timeout up. Next, this also uncovered a bug where our cancellation of http channels was a bit dodgy. This is changed to be a bit more robust, separating the "current" active http streams (for read or write) into separate tracking variables variables. Also, now cancellation immediately calls the aio finish for those -- there were assumptions elsewhere (expire timeouts) that cancellation caused nni_aio_finish() to be called. Finally there was a use after free bug in the websocket listener code where the listener could be freed while still having outstanding streams waiting to send the websocket reply.

* Add TLS configuration manipulation documentation.Garrett D'Amore2018-01-01
| | | | | | While here, also fixup the markup on many of the pages, to use commas in SEE ALSO, avoid adding the .adoc extension to cross-references, and correct the link to the MIT license text.

| | | | We forgot to bump for 0.1.0 even though we tagged.
* 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.
