Args: applications (dict[str,Application] or Application) : A map from paths to ``Application`` instances. If the value is a single Application, then the following mapping is generated: .. code-block:: python applications = { '/' : applications } When a connection comes in to a given path, the associate Application is used to generate a new document for the session. prefix (str, optional) : A URL prefix to use for all Bokeh server paths. (default: None) extra_websocket_origins (list[str], optional) : A list of hosts that can connect to the websocket. This is typically required when embedding a Bokeh server app in an external web site using :func:`~bokeh.embed.server_document` or similar. If None, ``["localhost"]`` will be assumed (default: None) extra_patterns (seq[tuple], optional) : A list of tuples of (str, http or websocket handler) Use this argument to add additional endpoints to custom deployments of the Bokeh Server. If None, then ``[]`` will be used. (default: None) secret_key (str, optional) : A secret key for signing session IDs. Defaults to the current value of the environment variable ``BOKEH_SECRET_KEY`` sign_sessions (bool, optional) : Whether to cryptographically sign session IDs Defaults to the current value of the environment variable ``BOKEH_SIGN_SESSIONS``. If ``True``, then ``secret_key`` must also be provided (either via environment setting or passed as a parameter value) generate_session_ids (bool, optional) : Whether to generate a session ID if one is not provided (default: True) keep_alive_milliseconds (int, optional) : Number of milliseconds between keep-alive pings (default: 37000) Pings normally required to keep the websocket open. Set to 0 to disable pings. check_unused_sessions_milliseconds (int, optional) : Number of milliseconds between checking for unused sessions (default: 17000) unused_session_lifetime_milliseconds (int, optional) : Number of milliseconds for unused session lifetime (default: 15000) stats_log_frequency_milliseconds (int, optional) : Number of milliseconds between logging stats (default: 15000) mem_log_frequency_milliseconds (int, optional) : Number of milliseconds between logging memory information (default: 0) Enabling this feature requires the optional dependency ``psutil`` to be installed. use_index (bool, optional) : Whether to generate an index of running apps in the ``RootHandler`` (default: True) index (str, optional) : Path to a Jinja2 template to serve as the index for "/" if use_index is True. If None, the basic built in app index template is used. (default: None) redirect_root (bool, optional) : When there is only a single running application, whether to redirect requests to ``"/"`` to that application automatically (default: True) If there are multiple Bokeh applications configured, this option has no effect. websocket_max_message_size_bytes (int, optional): Set the Tornado ``websocket_max_message_size`` value. (default: 20*1024*1024) NOTE: This setting has effect ONLY for Tornado>=4.5 Any additional keyword arguments are passed to ``tornado.web.Application``. cK`sˆd|_t|tƒr(i|d6}n|dkr=d}n|jdƒ}|r_d|}n||_||_|dkrŒtdƒ‚n;|dkr¨tj dƒn|t krΗtj d|ƒn||_ | dkrλtdƒ‚n| t kr tj d| ƒn| |_ | dkr.tdƒ‚n| tkrMtj d | ƒn| |_| dkrqtd ƒ‚n| tkrtj d | ƒn| |_| dkr΄td ƒ‚nV| dkr td ƒdkrθtjdƒd} q | tkr tj d| ƒq n| |_|dkr.tdƒ‚n&|tkrTtj d||d'ƒn|dkrotƒ|_nt|ƒ|_||_||_||_tjdt|jƒƒtƒ|_x3|j ƒD]%\}}t!|d|ƒ|j|= 0uKeep-alive ping disabledu0Keep-alive ping configured every %d millisecondsu.check_unused_sessions_milliseconds must be > 0u/Check for unused sessions every %d millisecondsu(Unused sessions last for %d millisecondsu,stats_log_frequency_milliseconds must be > 0u$Log statistics every %d millisecondsu+mem_log_frequency_milliseconds must be >= 0upsutilu†Memory logging requested, but is disabled.
