e8313084 2022-09-12 22:16:56 Add minimal WebSocket server implementation for evhttp (#1322) 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.
c22f2757 2022-07-09 23:27:23 Use OPENSSL_VERSION_NUMBER over OPENSSL_VERSION_MAJOR (for compatibility) 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.
29c420c4 2022-06-18 21:43:31 Initial OpenSSL 3.0 support * 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

e77f1872 2021-04-02 21:02:12 sample: use unsigned short instead of int for port 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.

02905413 2016-02-09 18:01:00 Add callback support for error pages 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)

2f184f8b 2019-03-26 13:33:57 evwatch: Add "prepare" and "check" watchers. Adds two new callbacks: "prepare" watchers, which fire immediately before we poll for I/O, and "check" watchers, which fire immediately after we finish polling and before we process events. This allows other event loops to be embedded into libevent's, and enables certain performance monitoring. Closes: #710

05318f13 2017-03-05 11:33:44 sample/https-client: use ERR_remove_*state() when we have them ERR_remove_thread_state: - openssl 0.9.8 does not have - openssl 1.0/libressl has - openssl 1.1 deprecates
5d18d879 2017-03-02 21:09:32 Do not check for ERR_remove_thread_state() (do not link ssl into every library) This reverts commit c4e9d9bd662de7f575f2172c160795d452ebe709 ("sample/https-client: check for ERR_remove_thread_state() existence"). Calling AC_SEARCH_LIBS() modifies LIBS - -lcrypto incorrectly ends up in LIBS, and thus linked to by libevent_core.so. Checking for ERR_remove_thread_state should no longer be needed because it was introduced in openssl 1.0.0, and the previous line 0.9.8 had support discontinued at the end of 2015. Fixes: #473
