See inner_main for request processing.
Client attributes at instantiation:
- "path" is the PATH_INFO inside the instance (with no leading '/')
- "base" is the base URL for the instance
- "form" is the cgi form, an instance of FieldStorage from the standard
- cgi module
- "additional_headers" is a dictionary of additional HTTP headers that
- should be sent to the client
- "response_code" is the HTTP response code to send to the client

+ cgi module
+ - "additional_headers" is a dictionary of additional HTTP headers that
+ should be sent to the client
+ - "response_code" is the HTTP response code to send to the client
During the processing of a request, the following attributes are used:
- "error_message" holds a list of error messages
- "ok_message" holds a list of OK messages
- "session" is the current user session id
- "user" is the current user's name
- "userid" is the current user's id
- "template" is the current :template context
- "classname" is the current class context name
- "nodeid" is the current context item id
+
+ - "error_message" holds a list of error messages
+ - "ok_message" holds a list of OK messages
+ - "session" is the current user session id
+ - "user" is the current user's name
+ - "userid" is the current user's id
+ - "template" is the current :template context
+ - "classname" is the current class context name
+ - "nodeid" is the current context item id
User Identification:
If the user has no login cookie, then they are anonymous and are logged
Once a user logs in, they are assigned a session. The Client instance
keeps the nodeid of the session as the "session" attribute.

- <propname>
- - property on the current context item
-
- <designator>:<propname>
- - property on the indicated item
-
- <classname>-<N>:<propname>
- - property on the Nth new item of classname
-
- Once we have determined the "propname", we check to see if it
- is one of the special form values:
-
- :required
- The named property values must be supplied or a ValueError
- will be raised.
-
- :remove:<propname>=id(s)
- The ids will be removed from the multilink property.
-
- :add:<propname>=id(s)
- The ids will be added to the multilink property.
-
- :link:<propname>=<designator>
- Used to add a link to new items created during edit.
- These are collected up and returned in all_links. This will
- result in an additional linking operation (either Link set or
- Multilink append) after the edit/create is done using
- all_props in _editnodes. The <propname> on the current item
- will be set/appended the id of the newly created item of
- class <designator> (where <designator> must be
- <classname>-<N>).
-
- Any of the form variables may be prefixed with a classname or
- designator.
-
- The return from this method is a dict of
- (classname, id): properties
- ... this dict _always_ has an entry for the current context,
- even if it's empty (ie. a submission for an existing issue that
- doesn't result in any changes would return {('issue','123'): {}})
- The id may be None, which indicates that an item should be
- created.
-
- If a String property's form value is a file upload, then we
- try to set additional properties "filename" and "type" (if
- they are valid for the class).
-
- Two special form values are supported for backwards
- compatibility:
- :note - create a message (with content, author and date), link
- to the context item. This is ALWAYS desginated "msg-1".
- :file - create a file, attach to the current item and any
- message created by :note. This is ALWAYS designated
- "file-1".
-
- We also check that FileClass items have a "content" property with
- actual content, otherwise we remove them from all_props before
- returning.
