The ContainerAwareTraceableEventDispatcher class was tied to both the
Symfony container and the HttpKernel profiler. It made it non reusable
in another context.
The new TraceableEventDispatcher only keeps the HttpKernel profiler
integration and is able to wrap any other event dispatcher. It makes it
reusable in frameworks using the Symfony HttpKernel component like
Silex.
The only drawback is that we don't have access to the listener
priorities in the collected data anymore (but the listeners are still
ordered correctly). The change is still worth it I think.
The charset was configurable in a configuration file but it never worked:
framework:
charset: ISO-8859-1
Now, like for the cache and log dirs, you can configure the charset by
overriding the getCharset() method in the app kernel:
public function getCharset()
{
return 'ISO-8859-1';
}
Before this commit, the current locale was stored in the session (if one
was already started). That way, for the next requests, even if the
request locale attribute was not set, the locale was "restored".
But this is a really bad practice as it means that the same URL can have
a different content depending on the previous requests. It would have
been better if the Vary header was set but the locale can be different
from the value coming from the Accept-Language anyway.
This is a BC break but fortunately, you can restore the 2.0 behavior by
creating a simple event listener that contains the logic removed by this
commit.
