Deprecate support for Logback Layout
Logback has deprecated the use of Layout in favour of Encoder. A LayoutWrappingEncoder adapter is provided to bridge between the two.
Logback OutputStreamAppender and sub-classes like ConsoleAppender still accept a Layout but wrap them with a LayoutWrappingEncoder and emit warnings saying:
This appender no longer admits a layout as a sub-component, set an encoder instead.
To ensure compatibility, wrapping your layout in LayoutWrappingEncoder.
See also http://logback.qos.ch/codes.html#layoutInsteadOfEncoder for details.
The SyslogAppender however is still using a Layout but does not allow to set it by configuration.
Supporting Layout in logstash-logback-encoder is cumbersome and increase code complexity for little to no benefit. Proposition is to deprecate it for removal in the next major release.
The SyslogAppender however is still using a Layout but does not allow to set it by configuration.
AbstractLogstashUdpSocketAppender extends SyslogAppenderBase, and allows the layout to be configured. It's typically configured with a Layout from logstash-logback-encoder.
If layout support is removed from logstash-logback-encoder, we'll need to copy the logic from SyslogAppenderBase into AbstractLogstashUdpSocketAppender
AbstractLogstashUdpSocketAppender extends SyslogAppenderBase...
Correct. We should definitely see how we can make the UdpSocketAppender use an Encoder (or else) before deprecating Layouts...
