* Add minimal WebSocket server implementation for evhttp (#1322)Dmitry Ilyin2022-09-123-0/+346
| | | | | | | | | | | | | | This adds few functions to use evhttp-based webserver to handle incoming WebSockets connections. We've tried to use both libevent and libwebsockets in our application, but found that we need to have different ports at the same time to handle standard HTTP and WebSockets traffic. This change can help to stick only with libevent library. Implementation was inspired by modified Libevent source code in ipush project [1]. [1]: https://github.com/sqfasd/ipush/tree/master/deps/libevent-2.0.21-stable Also, WebSocket-based chat server was added as a sample.
* Use OPENSSL_VERSION_NUMBER over OPENSSL_VERSION_MAJOR (for compatibility)Azat Khuzhin2022-07-102-3/+3
| | | | | | | | Since OpenSSL 3.0 there is new OPENSSL_VERSION_MAJOR, but previous releases does not have it. So let's use plain old OPENSSL_VERSION_NUMBER to avoid more preprocessor macros.
* Initial OpenSSL 3.0 supportWilliam Marlow2022-07-092-0/+14
| | | | | | | * Don't use deprecated functions when building against OpenSSL 3.0. * Recognise that OpenSSL 3.0 can signal a dirty shutdown as a protocol. error in addition to the expected IO error produced by OpenSSL 1.1.1 * Update regress_mbedtls.c for compatibility with OpenSSL 3
* sample/ssl-client-mbedtls.c: fix for MbedTLS 3Azat Khuzhin2022-07-091-9/+46
| | | | | | | | - use build_info.h over version.h - provide own certs P.S. since it is simpler then adding detection of the library version into autotools.

* sample: use unsigned short instead of int for portEmil Engler2021-04-031-1/+1
| | | | | | | The C standard gurantees that an unsigned short is at least up to 65535 huge. Enough to store every TCP port. Also the parameter PORT is overgiven to the `htons()` function which assumes that the parameter is of type `uint16_t` which unsigned short is on most platforms.

* Add callback support for error pagesnntrab2020-01-131-1/+1
| | | | | | | | | | | | | | | | | | | | | The existing error pages are very basic and don't allow for multi-lingual support or for conformity with other pages in a web site. The aim of the callback functionality is to allow custom error pages to be supported for calls to evhttp_send_error() by both calling applications and Libevent itself. A backward-incompatible change has been made to the title of error pages sent by evhttp_send_error(). The original version of the function used the reason argument as part of the title. That might have unforeseen side-effects if it contains HTML tags. Therefore the title has been changed to always use the standard status text. An example of the error callback can be found in this [version](https://github.com/libevent/libevent/files/123607/http-server.zip) of the 'http-server' sample. It will output error pages with very bright backgrounds, the error code using a very large font size and the reason. Closes: #323 (cherr-picked from PR)
