`OneShotAppServer
This version of the app server is in support of the OneShot adapter.
This class creates an application that has no session sweeper thread,
and it provides the convenience method dispatchRawRequest().
See also: OneShot.cgi and OneShotAdapter.py.`

Methods inherited from WebKit.AppServer.AppServer:

application(self)
  `Return the Application singleton.`

checkForInstall(self)
  `Check whether Webware was installed.
  Exits with an error message if Webware was not installed.
  Called from `__init__`.`

closeThread(self)
  `This method is called when the shutdown sequence is initiated.`

configFilename(self)
  `Return the name of the AppServer configuration file.`

configReplacementValues(self)
  `Get config values that need to be escaped.`

defaultConfig(self)
  `Return the default configuration.`

error(self, msg)
  `Output an error.
  Flushes stdout and stderr, prints the message to stderr
  and exits with code 1.`

initiateShutdown(self)
  `Ask the master thread to begin the shutdown.`

loadPlugIn(self, path)
  `Load and return the given plug-in.
  May return None if loading was unsuccessful (in which case this method
  prints a message saying so). Used by `loadPlugIns` (note the **s**).`

loadPlugIns(self)
  `Load all plug-ins.
  A plug-in allows you to extend the functionality of WebKit without
  necessarily having to modify its source. Plug-ins are loaded by
  AppServer at startup time, just before listening for requests.
  See the docs in `WebKit.PlugIn` for more info.`

numRequests(self)
  `Return the number of requests.
  Returns the number of requests received by this app server
  since it was launched.`

plugIn(self, name, default=<class MiscUtils.NoDefault>)
  `Return the plug-in with the given name.`

plugIns(self)
  `Return a list of the plug-ins loaded by the app server.
  Each plug-in is a Python package.`

printStartUpMessage(self)
  `Invoked by __init__, prints a little intro.`

readyForRequests(self)
  `Declare ready for getting requests.
  Should be invoked by subclasses when they are finally ready to
  accept requests. Records some stats and prints a message.`

recordPID(self)
  `Save the pid of the AppServer to a file.`

serverSidePath(self, path=None)
  `Return the absolute server-side path of the WebKit app server.
  If the optional path is passed in, then it is joined with the
  server side directory to form a path relative to the app server.`

shutDown(self)
  `Shut down the AppServer.
  Subclasses may override and normally follow this sequence:
  1. set self.running = 1 (request to shut down)
  2. class specific statements for shutting down
  3. Invoke super's shutDown() e.g., ``AppServer.shutDown(self)``
  4. set self.running = 0 (server is completely down)`

startTime(self)
  `Return the time the app server was started.
  The time is given as seconds, like time().`

version(self)
  `Return WebKit version.`

warning(self, msg)
  `Output a warning (not yet implemented).`

webKitPath(self)
  `Return teh WebKit path.`

webwarePath(self)
  `Return the Webware path.`

Methods inherited from WebKit.ConfigurableForServerSidePath.ConfigurableForServerSidePath:

setting(self, name, default=<class MiscUtils.NoDefault>)
  `Returns the setting, filtered by
  serverSidePath(), if the name ends with
  ``Filename`` or ``Dir``.`

Methods inherited from MiscUtils.Configurable.Configurable:

commandLineConfig(self)
  `Settings that came from the command line (via
  addCommandLineSetting).`

config(self)
  `Returns the configuration of the object as a dictionary. This is a combination of defaultConfig() and userConfig(). This method caches the config.`

configName(self)
  `Returns the name of the configuration file (the portion
  before the '.config'). This is used on the command-line.`

hasSetting(self, name)

printConfig(self, dest=None)
  `Prints the configuration to the given destination, which defaults to stdout. A fixed with font is assumed for aligning the values to start at the same column.`

setSetting(self, name, value)

userConfig(self)
  `Returns the user config overrides found in the optional config file, or {} if there is no such file. The config filename is taken from configFilename().`

Methods inherited from WebKit.Object.Object:

deprecated(self, method)
  `Output a deprecation warning.
  The implementation of WebKit sometimes invokes this method which prints
  a warning that the method you are using has been deprecated.
  This method expects that deprecated methods say so at the beginning of
  their doc string and terminate that msg with @. For example:
  DEPRECATED: Class.foo() on 01/24/01 in ver 0.5. Use Class.bar() instead. @
  Putting this information in the doc string is important for accuracy
  in the generated docs.
  Example call:
  deprecated(self.foo)`

Data and other attributes inherited from WebKit.Object.Object:

__dict__ = <dictproxy object>
  `dictionary for instance variables (if defined)`

__weakref__ = <attribute '__weakref__' of 'Object' objects>
  `list of weak references to the object (if defined)`

Methods inherited from MiscUtils.NamedValueAccess.NamedValueAccess:

hasValueForKey(self, key)
  `Returns true if the key is available, although that does not
  guarantee that there will not be errors caused by retrieving the key.`

hasValueForName(self, keysString)

resetKeyBindings(self)

setValueForKey(self, key, value)
  `Suppose key is 'foo'. This method sets the value with the following precedence:
  1. Public attributes before private attributes
  2. Methods before non-methods
  More specifically, this method then uses one of the following:
  @@ 2000-03-04 ce: fill in
  ...or invokes handleUnknownSetKey().`

valueForKey(self, key, default=<class MiscUtils.NoDefault>)
  `Suppose key is 'foo'. This method returns the value with the following precedence:
  1. Methods before non-methods
  2. Public attributes before private attributes
  More specifically, this method then returns one of the following:
  * foo()
  * _foo()
  * self.foo
  * self._foo
  ...or default, if it was specified,
  otherwise invokes and returns result of valueForUnknownKey().
  Note that valueForUnknownKey(), normally returns an exception.
  See valueForName() which is a more advanced version of this method that allows
  multiple, qualified keys.`

valueForKeySequence(self, listOfKeys, default=None)

valueForName(self, keysString, default=None)
  `Returns the value for the given keysString. This is the more advanced version of
  valueForKey(), which can only handle single names. This method can handle
  'foo', 'foo1.foo2', 'a.b.c.d', etc. It will traverse dictionaries if needed.`

valueForUnknownKey(self, key, default)
  `# Errors`

valuesForNames(self, keys, default=None, defaults=None, forgive=0, includeNames=0)
  `Returns a list of values that match the given keys, each of which is passed
  through valueForName() and so could be of the form 'a.b.c'.
  keys is a sequence. default is any kind of object. defaults is a sequence.
  forgive and includeNames is a flag.
  If default is not None, then it is substituted when a key is not found.
  Otherwise, if defaults is not None, then it's corresponding/parallel value
  for the current key is substituted when a key is not found.
  Otherwise, if forgive=1, then unknown keys simply don't produce any values.
  Otherwise, if default and defaults are None, and forgive=0, then the unknown
  keys will probably raise an exception through valueForUnknownKey() although
  that method can always return a final, default value.
  if keys is None, then None is returned. If keys is an empty list, then None
  is returned.
  Often these last four arguments are specified by key.
  Examples:
  names = ['origin.x', 'origin.y', 'size.width', 'size.height']
  obj.valuesForNames(names)
  obj.valuesForNames(names, default=0.0)
  obj.valuesForNames(names, defaults=[0.0, 0.0, 100.0, 100.0])
  obj.valuesForNames(names, forgive=0)
  @@ 2000-03-04 ce: includeNames is only supported when forgive=1.
  It should be supported for the other cases.
  It should be documented.
  It should be included in the test cases.`
