20 An e-mail gateway for Roundup.
22 Incoming messages are examined for multiple parts:
23 . In a multipart/mixed message or part, each subpart is extracted and
24 examined. The text/plain subparts are assembled to form the textual
25 body of the message, to be stored in the file associated with a "msg"
26 class node. Any parts of other types are each stored in separate files
27 and given "file" class nodes that are linked to the "msg" node.
28 . In a multipart/alternative message or part, we look for a text/plain
29 subpart and ignore the other parts.
31 Summary
32 -------
33 The "summary" property on message nodes is taken from the first non-quoting
34 section in the message body. The message body is divided into sections by
35 blank lines. Sections where the second and all subsequent lines begin with
36 a ">" or "|" character are considered "quoting sections". The first line of
37 the first non-quoting section becomes the summary of the message.
39 Addresses
40 ---------
41 All of the addresses in the To: and Cc: headers of the incoming message are
42 looked up among the user nodes, and the corresponding users are placed in
43 the "recipients" property on the new "msg" node. The address in the From:
44 header similarly determines the "author" property of the new "msg"
45 node. The default handling for addresses that don't have corresponding
46 users is to create new users with no passwords and a username equal to the
47 address. (The web interface does not permit logins for users with no
48 passwords.) If we prefer to reject mail from outside sources, we can simply
49 register an auditor on the "user" class that prevents the creation of user
50 nodes with no passwords.
52 Actions
53 -------
54 The subject line of the incoming message is examined to determine whether
55 the message is an attempt to create a new item or to discuss an existing
56 item. A designator enclosed in square brackets is sought as the first thing
57 on the subject line (after skipping any "Fwd:" or "Re:" prefixes).
59 If an item designator (class name and id number) is found there, the newly
60 created "msg" node is added to the "messages" property for that item, and
61 any new "file" nodes are added to the "files" property for the item.
63 If just an item class name is found there, we attempt to create a new item
64 of that class with its "messages" property initialized to contain the new
65 "msg" node and its "files" property initialized to contain any new "file"
66 nodes.
68 Triggers
69 --------
70 Both cases may trigger detectors (in the first case we are calling the
71 set() method to add the message to the item's spool; in the second case we
72 are calling the create() method to create a new node). If an auditor raises
73 an exception, the original message is bounced back to the sender with the
74 explanatory message given in the exception.

1118 # . roundup-admin create now prompts for property info if none is supplied
1119 # on the command-line.
1120 # . hyperdb Class getprops() method may now return only the mutable
1121 # properties.
1122 # . Login now uses cookies, which makes it a whole lot more flexible. We can
1123 # now support anonymous user access (read-only, unless there's an
1124 # "anonymous" user, in which case write access is permitted). Login
1125 # handling has been moved into cgi_client.Client.main()
1126 # . The "extended" schema is now the default in roundup init.
1127 # . The schemas have had their page headings modified to cope with the new
1128 # login handling. Existing installations should copy the interfaces.py
1129 # file from the roundup lib directory to their instance home.
1130 # . Incorrectly had a Bizar Software copyright on the cgitb.py module from
1131 # Ping - has been removed.
1132 # . Fixed a whole bunch of places in the CGI interface where we should have
1133 # been returning Not Found instead of throwing an exception.
1134 # . Fixed a deviation from the spec: trying to modify the 'id' property of
1135 # an item now throws an exception.
