example application for a complete example that uses authentication (and stores user data in a PostgreSQL database). Third party authentication The tornado.auth module implements the authentication and begin in clear-text mode and switch to SSL after some initial negotiation (such as the STARTTLS extension to SMTP and IMAP). This method cannot be used if there are outstanding reads or writes on the stream resolve. • The tornado.websocket module now supports compression via the “permessage-deflate” extension. Override WebSocketHandler.get_compression_options to enable on the server side, and use the compression_options

example the non-standard version number v"0.3-" is used, with a trailing -: this notation is a Julia extension of the standard, and it's used to indicate a version which is lower than any 0.3 release, including check should be modified like this: v"0.2-" <= VERSION. Another non-standard version specification extension allows one to use a trailing + to express an upper limit on build versions, e.g. VERSION > v"0 METHODS 170 input = convert(AbstractArray{Eltype}, input) output = similar(input, Eltype) As an extension of this, in cases where the algorithm needs a copy of the input array, convert is insufficient
