Announcing mod_websocket v0.1.2

Jul 15, 2020, 7:12 PM

Post #1 of 3 (320 views)

I'm happy to announce version 0.1.2 of mod_websocket:

https://github.com/jchampio/apache-websocket/releases/tag/0.1.2

mod_websocket is an Apache 2.x module that allows developers to write C-
and C++-based WebSocket services. The intent is for mod_websocket plugin
writers to develop their services independently of the Apache server API.

This is a "dust off the build" release -- the user-facing changes have
been in master for four years, but never officially released. One major
bug has been fixed, a few minor cleanups have been made, and a new build
system for *nix platforms was contributed to the project. I am also
dropping testing coverage for the obsolete 2.2 server line, though I
won't intentionally break 2.2 features until a future 0.2 release.

= Major New Features/Fixes =

- Extremely fragmented messages no longer cause poor performance and
possible DoS conditions. Thanks to Paul Spangler for his fix
suggestion!
- The CMake build system now supports *nix platforms as well as Windows.
Thanks to @toniotelli for the contribution!
- The 'MaxMessageSize' directive has been renamed to
'WebSocketMaxMessageSize'; its previous spelling is deprecated and
will be removed in the future.

A full changelist can be seen at the release description on GitHub.

= Major Known Issues =

This is a pre-release, zero-dot module. There are known issues that may
preclude its use in production systems. Please understand them and take
steps to avoid them if you decide to deploy mod_websocket.

- Apache worker threads are completely monopolized by WebSocket
connections. This makes it possible for a large number of connections
to DoS the server.

A more complete (but not necessarily exhaustive) list is available at
the repo page on GitHub:

https://github.com/jchampio/apache-websocket/issues

= What's Next =

There's a lot of stuff to do. During my absence from the project,
WebSocket has received a transport based on HTTP/2, several optional
WebSocket features have seen more mainstream use, and Python 2 was
EoL'd. And the existing issues list didn't become any shorter,
unfortunately.

Questions? Comments? Let me know. Thanks for your interest!

Build with vcxproj and tested on Windows VS16.

All looks fine : [websocket:info] [pid 2428:tid 2268] [client
::1:50195] established new WebSocket connection
Only a few warninf:

mod_websocket.c(1186,57): warning C4244: 'function': conversion from
'apr_int64_t' to 'apr_size_t', possible loss of data
mod_websocket.c(1253,37): warning C4244: 'function': conversion from
'apr_int64_t' to 'size_t', possible loss of data
mod_websocket.c(1282,45): warning C4244: '+=': conversion from
'apr_int64_t' to 'apr_size_t', possible loss of data
mod_websocket\mod_websocket.c(1283,46): warning C4244: '+=':
conversion from 'apr_int64_t' to 'apr_size_t', possible loss of data

Is it ok that I make available at
https://www.apachelounge.com/download/ ?

Below I running with Windows 32 and using the example
mod_websocket_echo.so.

But with Windows 64 it is not running:

AH00526: Syntax error on line 122 of C:/Apache24/conf/httpd.conf:
Could not find initialization function "_echo_init@0" for
WebSocketHandler modules/mod_websocket_echo.so

When I change _echo_init@0 it is running.

So with:
Win32 : find initialization function "_echo_init@0"
Win64 : find initialization function "echo_init"

conf:
LoadModule websocket_module modules/mod_websocket.so

<IfModule mod_websocket.c>
<Location /echo>
SetHandler websocket-handler
WebSocketHandler modules/mod_websocket_echo.so _echo_init@0
</Location>
</IfModule>

Running the latest 2.4.44-dev
