#------------------------------------------------------------------------------
# BaseBeakerApp(ServerApp) configuration
#------------------------------------------------------------------------------
## Customizable ServerApp for use with Beaker

## Username for the Beaker kernel agent process
#  Default: ''
# c.BaseBeakerApp.agent_user = ''

## Set the Access-Control-Allow-Credentials: true header
#  Default: False
# c.BaseBeakerApp.allow_credentials = False

## Whether or not to allow external kernels, whose connection files are placed in
#  external_connection_dir.
#  Default: False
# c.BaseBeakerApp.allow_external_kernels = False

#  Default: '*'
# c.BaseBeakerApp.allow_origin = '*'

## Use a regular expression for the Access-Control-Allow-Origin header
#
#          Requests from an origin matching the expression will get replies with:
#
#              Access-Control-Allow-Origin: origin
#
#          where `origin` is the origin of the request.
#
#          Ignored if allow_origin is set.
#  Default: ''
# c.BaseBeakerApp.allow_origin_pat = ''

## Allow requests where the Host header doesn't point to a local server
#
#         By default, requests get a 403 forbidden response if the 'Host' header
#         shows that the browser thinks it's on a non-local domain.
#         Setting this option to True disables this check.
#
#         This protects against 'DNS rebinding' attacks, where a remote web server
#         serves you a page and then changes its DNS to send later requests to a
#         local IP, bypassing same-origin checks.
#
#         Local IP addresses (such as 127.0.0.1 and ::1) are allowed as local,
#         along with hostnames configured in local_hostnames.
#  Default: False
# c.BaseBeakerApp.allow_remote_access = False

## Whether to allow the user to run the server as root.
#  Default: False
# c.BaseBeakerApp.allow_root = False

## Allow unauthenticated access to endpoints without authentication rule.
#
#          When set to `True` (default in jupyter-server 2.0, subject to change
#          in the future), any request to an endpoint without an authentication rule
#          (either `@tornado.web.authenticated`, or `@allow_unauthenticated`)
#          will be permitted, regardless of whether user has logged in or not.
#
#          When set to `False`, logging in will be required for access to each endpoint,
#          excluding the endpoints marked with `@allow_unauthenticated` decorator.
#
#          This option can be configured using `JUPYTER_SERVER_ALLOW_UNAUTHENTICATED_ACCESS`
#          environment variable: any non-empty value other than "true" and "yes" will
#          prevent unauthenticated access to endpoints without `@allow_unauthenticated`.
#  Default: True
# c.BaseBeakerApp.allow_unauthenticated_access = True

## Answer yes to any prompts.
#  Default: False
# c.BaseBeakerApp.answer_yes = False

#  Default: ''

# c.BaseBeakerApp.beaker_config_path = traitlets.Undefined

#  Default: {}
# c.BaseBeakerApp.beaker_extension_app = {}

## Specify what command to use to invoke a web
#                        browser when starting the server. If not specified, the
#                        default browser will be determined by the `webbrowser`
#                        standard library module, which allows setting of the
#                        BROWSER environment variable to override it.

## The random bytes used to secure cookies.
#          By default this is generated on first start of the server and persisted across server
#          sessions by writing the cookie secret into the `cookie_secret_file` file.
#          When using an executable config file you can override this to be random at each server restart.
#
#          Note: Cookie secrets should be kept private, do not share config files with
#          cookie_secret stored in plaintext (you can read the value from a file).
#  Default: b''
# c.BaseBeakerApp.cookie_secret = b''

## The file where the cookie secret is stored.
#  Default: ''
# c.BaseBeakerApp.cookie_secret_file = ''

## Override URL shown to users.
#
#          Replace actual URL, including protocol, address, port and base URL,
#          with the given value when displaying URL to the users. Do not change
#          the actual connection URL. If authentication token is enabled, the
#          token is added to the custom URL automatically.
#
#          This option is intended to be used when the URL to display to the user
#          cannot be determined reliably by the Jupyter server (proxified

## The full path to a private key file for usage with SSL/TLS.
#  Default: ''
# c.BaseBeakerApp.keyfile = ''

## Hostnames to allow as local when allow_remote_access is False.
#
#         Local IP addresses (such as 127.0.0.1 and ::1) are automatically accepted
#         as local as well.

#  Default: 30
# c.BaseBeakerApp.log_level = 30

## Enable request logging
#  Default: False
# c.BaseBeakerApp.log_requests = False

## Configure additional log handlers.
#
#  The default stderr logs handler is configured by the log_level, log_datefmt
#  and log_format settings.
#
#  This configuration can be used to configure additional handlers (e.g. to
#  output the log to a file) or for finer control over the default handlers.
#
#  If provided this should be a logging configuration dictionary, for more
#  information see:
#  https://docs.python.org/3/library/logging.config.html#logging-config-
#  dictschema
#
#  This dictionary is merged with the base logging configuration which defines
#  the following:
#
#  * A logging formatter intended for interactive use called
#    ``console``.
#  * A logging handler that writes to stderr called
#    ``console`` which uses the formatter ``console``.
#  * A logger with the name of this application set to ``DEBUG``
#    level.
#
#  This example adds a new handler that writes to a file:

# c.BaseBeakerApp.logout_handler_class = 'jupyter_server.auth.logout.LogoutHandler'

## Sets the maximum allowed size of the client request body, specified in the
#  Content-Length request header field. If the size in a request exceeds the
#  configured value, a malformed HTTP message is returned to the client.
#
#  Note: max_body_size is applied even in streaming mode.
#  Default: 536870912
# c.BaseBeakerApp.max_body_size = 536870912

## Gets or sets the maximum amount of memory, in bytes, that is allocated for use
#  by the buffer manager.
#  Default: 536870912
# c.BaseBeakerApp.max_buffer_size = 536870912

## Gets or sets a lower bound on the open file handles process resource limit.
#  This may need to be increased if you run into an OSError: [Errno 24] Too many
#  open files. This is not applicable when running on Windows.
#  Default: 0
# c.BaseBeakerApp.min_open_files_limit = 0

#  Default: 'beaker'

#  Default: False
# c.BaseBeakerApp.show_config = False

## Instead of starting the Application, dump configuration to stdout (as JSON)
#  Default: False
# c.BaseBeakerApp.show_config_json = False

## Shut down the server after N seconds with no kernelsrunning and no activity.
#  This can be used together with culling idle kernels
#  (MappingKernelManager.cull_idle_timeout) to shutdown the Jupyter server when
#  it's not in use. This is not precisely timed: it may shut down up to a minute
#  later. 0 (the default) disables this automatic shutdown.
#  Default: 0
# c.BaseBeakerApp.shutdown_no_activity_timeout = 0

## The UNIX socket the Jupyter server will listen on.
#  Default: ''
# c.BaseBeakerApp.sock = ''

#  Default: {}
# c.BaseBeakerApp.terminado_settings = {}

## Set to False to disable terminals.
#
#           This does *not* make the server more secure by itself.
#           Anything the user can in a terminal, they can also do in a notebook.
#
#           Terminals may also be automatically disabled if the terminado package
#           is not available.
#  Default: False
# c.BaseBeakerApp.terminals_enabled = False

## Supply overrides for the tornado.web.Application that the Jupyter server uses.

# c.BaseBeakerApp.trust_xheaders = False

## Working directory for kernel execution and file operations
#  Default: ''
# c.BaseBeakerApp.ui_path = ''

## Disable launching browser by redirect file
#       For versions of notebook > 5.7.2, a security feature measure was added that
#       prevented the authentication token used to launch the browser from being visible.
#       This feature makes it difficult for other users on a multi-user system from
#       running code in your Jupyter session as you.
#       However, some environments (like Windows Subsystem for Linux (WSL) and Chromebooks),
#       launching a browser using a redirect file can lead the browser failing to load.
#       This is because of the difference in file structures/paths between the runtime and
#       the browser.
#
#       Disabling this setting to False will disable this behavior, allowing the browser
#       to launch by using a URL and visible token (as before).
#  Default: True
# c.BaseBeakerApp.use_redirect_file = True

## Specify where to open the server on startup. This is the
#          `new` argument passed to the standard library method `webbrowser.open`.
#          The behaviour is not guaranteed, but depends on browser support. Valid
#          values are:
#
#           - 2 opens a new tab,
#           - 1 opens a new window,
#           - 0 opens in an existing window.
#
#          See the `webbrowser.open` documentation for details.
#  Default: 2
# c.BaseBeakerApp.webbrowser_open_new = 2

## Set the tornado compression options for websocket connections.
#
#  This value will be returned from
#  :meth:`WebSocketHandler.get_compression_options`. None (default) will disable
#  compression. A dict (even an empty one) will enable compression.
#
#  See the tornado docs for WebSocketHandler.get_compression_options for details.
#  Default: None
# c.BaseBeakerApp.websocket_compression_options = None

## Configure the websocket ping interval in seconds.
#
#  Websockets are long-lived connections that are used by some Jupyter Server
#  extensions.
#
#  Periodic pings help to detect disconnected clients and keep the connection
#  active. If this is set to None, then no pings will be performed.
#
#  When a ping is sent, the client has ``websocket_ping_timeout`` seconds to
#  respond. If no response is received within this period, the connection will be
#  closed from the server side.
#  Default: 0
# c.BaseBeakerApp.websocket_ping_interval = 0

## Configure the websocket ping timeout in seconds.
#
#  See ``websocket_ping_interval`` for details.
#  Default: 0
# c.BaseBeakerApp.websocket_ping_timeout = 0

## The base URL for websockets,
#          if it differs from the HTTP server (hint: it almost certainly doesn't).
#
#          Should be in the form of an HTTP origin: ws[s]://hostname[:port]
#  Default: ''
# c.BaseBeakerApp.websocket_url = ''

## Working directory for kernel execution and file operations
#  Default: ''
# c.BaseBeakerApp.working_dir = ''

#------------------------------------------------------------------------------

#  set_secure_cookie docs for details.
#  Default: {}
# c.BeakerIdentityProvider.cookie_options = {}

## Extra keyword arguments to pass to `get_secure_cookie`. See tornado's
#  get_secure_cookie docs for details.
#  Default: {}
# c.BeakerIdentityProvider.get_secure_cookie_kwargs = {}

## The login handler class to use, if any.
#  Default: 'jupyter_server.auth.login.LoginFormHandler'

#  only).Only needed when protocol-detection gives the wrong answer due to
#  proxies.
#  Default: None
# c.BeakerIdentityProvider.secure_cookie = None

## Token used for authenticating first-time connections to the server.
#
#          The token can be read from the file referenced by JUPYTER_TOKEN_FILE or set directly
#          with the JUPYTER_TOKEN environment variable.
#
#          When no password is enabled,
#          the default is to generate a new, random token.
#
#          Setting to an empty string disables authentication altogether, which
#  is NOT RECOMMENDED.
#
#          Prior to 2.0: configured as ServerApp.token
#  Default: '<generated>'
# c.BeakerIdentityProvider.token = '<generated>'

## If True, deleting a non-empty directory will always be allowed.
#          WARNING this may result in files being permanently removed; e.g. on Windows,
#          if the data size is too big for the trash/recycle bin the directory will be permanently
#          deleted. If False (default), the non-empty directory will be sent to the trash only

# c.BeakerContentsManager.delete_to_trash = True

#  Default: None
# c.BeakerContentsManager.event_logger = None

## handler class to use when serving raw file requests.
#
#          Default is a fallback that talks to the ContentsManager API,
#          which may be inefficient, especially for large files.
#
#          Local files-based ContentsManagers can use a StaticFileHandler subclass,
#          which will be much more efficient.
#
#          Access to these files should be Authenticated.
#  Default: 'jupyter_server.files.handlers.FilesHandler'
# c.BeakerContentsManager.files_handler_class = 'jupyter_server.files.handlers.FilesHandler'

## Extra parameters to pass to files_handler_class.
#
#          For example, StaticFileHandlers generally expect a `path` argument
#          specifying the root directory from which to serve files.
#  Default: {}
# c.BeakerContentsManager.files_handler_params = {}

## Hash algorithm to use for file content, support by hashlib

## Python callable or importstring thereof
#
#          to be called on the path of a file just saved.
#
#          This can be used to process the file on disk,

#  message spec. The Session will handle serialization/deserialization, security,
#  and metadata.
#
#  Sessions support configurable serialization via packer/unpacker traits, and
#  signing with HMAC digests via the key/keyfile traits.
#
#  Parameters ----------
#
#  debug : bool
#      whether to trigger extra debugging statements
#  packer/unpacker : str : 'json', 'pickle' or import_string
#      importstrings for methods to serialize message parts.  If just
#      'json' or 'pickle', predefined JSON and pickle packers will be used.
#      Otherwise, the entire importstring must be used.
#
#      The functions must accept at least valid JSON input, and output *bytes*.
#
#      For example, to use msgpack:
#      packer = 'msgpack.packb', unpacker='msgpack.unpackb'
#  pack/unpack : callables
#      You can also set the pack/unpack callables for serialization directly.
#  session : bytes

#  username : unicode
#      username added to message headers.  The default is to ask the OS.
#  key : bytes
#      The key used to initialize an HMAC signature.  If unset, messages
#      will not be signed or checked.
#  keyfile : filepath
#      The file containing a key.  If this is set, `key` will be initialized
#      to the contents of the file.

#  empty string is passed, select the legacy protocol. If None, the selected
#  protocol will depend on what the front-end supports (usually the most recent
#  protocol supported by the back-end and the front-end).
#  Default: None
# c.BaseKernelWebsocketConnection.kernel_ws_protocol = None

# ZMQChannelsWebsocketConnection(BaseKernelWebsocketConnection) configuration
#------------------------------------------------------------------------------
## A Jupyter Server Websocket Connection

## (bytes/sec)
#          Maximum rate at which stream output can be sent on iopub before they are
#          limited.
#  Default: 1000000
# c.ZMQChannelsWebsocketConnection.iopub_data_rate_limit = 1000000

## (msgs/sec)
#          Maximum rate at which messages can be sent on iopub before they are
#          limited.
#  Default: 1000
# c.ZMQChannelsWebsocketConnection.iopub_msg_rate_limit = 1000

## Whether to limit the rate of IOPub messages (default: True). If True, use
#  iopub_msg_rate_limit, iopub_data_rate_limit and/or rate_limit_window to tune
#  the rate.
#  Default: True
# c.ZMQChannelsWebsocketConnection.limit_rate = True

## (sec) Time window used to
#          check the message and data rate limits.
#  Default: 3
# c.ZMQChannelsWebsocketConnection.rate_limit_window = 3

# NotebookNotary(LoggingConfigurable) configuration
#------------------------------------------------------------------------------
## A class for computing and verifying notebook signatures.

## The hashing algorithm used to sign notebooks.
#  Choices: any of ['sha384', 'sha512', 'blake2s', 'sha3_256', 'sha224', 'md5', 'sha3_384', 'sha3_224', 'sha256', 'sha1', 'sha3_512', 'blake2b']
#  Default: 'sha256'
# c.NotebookNotary.algorithm = 'sha256'

## The storage directory for notary secret and database.
#  Default: ''
# c.NotebookNotary.data_dir = ''

## The sqlite file in which to store notebook signatures.
#          By default, this will be in your Jupyter data directory.
#          You can set it to ':memory:' to disable sqlite writing to the filesystem.
#  Default: ''
# c.NotebookNotary.db_file = ''

## The secret key with which notebooks are signed.
#  Default: b''
# c.NotebookNotary.secret = b''

## The file where the secret key is stored.
#  Default: ''
# c.NotebookNotary.secret_file = ''

## A callable returning the storage backend for notebook signatures.
#           The default uses an SQLite database.
#  Default: traitlets.Undefined
# c.NotebookNotary.store_factory = traitlets.Undefined
