crazy sized log messages in ConnectionHandler

[fommil]

I'm using spray-can directly for some low level stuff and when my code hits this line:

spray/spray-io/src/main/scala/spray/io/ConnectionHandler.scala

Line 44 in ccc3f20

case ev ⇒ log.warning("event pipeline: dropped {}", ev)

well, wow, I can say goodbye to the harddrive, because it prints out multi-multi-gigabyte log messages that look something like:

[WARN] [07/02/2015 14:04:31.313] [default-akka.actor.default-dispatcher-4] [akka://default/user/IO-HTTP/group-0/0] event pipeline: dropped CommandFailed(Write(ByteString(-127, 127, 0, 0, 0, 0, 0, 96, 0, 0 ... LOTS AND LOTS OF BYTE NUMBERS ...

I've noticed others have encountered the same thing, e.g. dcaoyuan/spray-websocket#24

Is there anything can be done? The only workaround I can see is to change the logging level to ERROR to avoid seeing it in the logs.

fyi, this will silence it (along with a bunch of other stuff that I'd rather not silence). I might have the possibility of override these methods

  <!-- WORKAROUND: https://github.com/spray/spray/issues/1060 -->
  <logger name="spray.can.client.HttpClientConnection" level="ERROR" />

ok, I was able to workaround by providing an HttpClientConnection with these methods overriden and then in the two locations that log out the warning, change them to just log the class of the message.

An alternative solution might be for akka.io ByteString to not implement toString! I'll create a ticket for that.
