If an exception happens in the query path, we'll never know about it. They are currently being ignored. Investigating this, I found out that this is because the readers in storage_proxy.cc handles them - but don't log they anywhere. This patch introduces such logging. the error() function takes an sstring not an exception_ptr: this is so we can reuse it in the future to also log problems from other hosts (currently not done). We have a separate helper to extract the message from the current exception before we pass it to error() Fixes #110 Signed-off-by: Glauber Costa <glommer@cloudius-systems.com>
