evb privilege - with this privilege users evade blocking of communication functionality defined by blocks placed by users with dcm privilege.
dcm privilege - this is now used to determine if link to block setting is displayed.
loncommon::findallcourses() now return a hash, where the keys are courseIDs instead of an array of courseIDs. Places where findallcourses() was called - lonannounce, lonpickcourse changed accordingly.
loncommon::findallcourses() now reports courses for a user where the user's only role was a custom role.
lonnet::allowed() can now take a fourth optional argument ($role) which allows privs to be investigated for roles other than the user's currently active role
&blockcheck, &parse_block_record(), and &build_block_table() moved from lonmsgdisplay to loncommon, so they are available for evaluation of blocking state for other communication functions besides COM.
Each block record for a blocking event in a course is now a hash, with key=values of the hash being setter = username:domain of user who set block, title=event title for block, and blocks = hash of blocked features ('com','chat','boards','port','groups').
Backwards compatibility retained with previous : separated text for block record value.

34: =head1 NAME
35:
36: Apache::lonmsg: supports internal messaging
37:
38: =head1 SYNOPSIS
39:
40: lonmsg provides routines for sending messages, receiving messages, and
41: a handler to allow users to read, send, and delete messages.
42:
43: =head1 OVERVIEW
44:
45: =head2 Messaging Overview
46:
47: X<messages>LON-CAPA provides an internal messaging system similar to
48: email, but customized for LON-CAPA's usage. LON-CAPA implements its
49: own messaging system, rather then building on top of email, because of
50: the features LON-CAPA messages can offer that conventional e-mail can
51: not:
52:
53: =over 4
54:
55: =item * B<Critical messages>: A message the recipient B<must>
56: acknowlegde receipt of before they are allowed to continue using the
57: system, preventing a user from claiming they never got a message
58:
59: =item * B<Receipts>: LON-CAPA can reliably send reciepts informing the
60: sender that it has been read; again, useful for preventing students
61: from claiming they did not see a message. (While conventional e-mail
62: has some reciept support, it's sporadic, e-mail client-specific, and
63: generally the receiver can opt to not send one, making it useless in
64: this case.)
65:
66: =item * B<Context>: LON-CAPA knows about the sender, such as where
67: they are in a course. When a student mails an instructor asking for
68: help on the problem, the instructor receives not just the student's
69: question, but all submissions the student has made up to that point,
70: the user's rendering of the problem, and the complete view the student
71: saw of the resource, including discussion up to that point. Finally,
72: the instructor is reading all of this inside of LON-CAPA, not their
73: email program, so they have full access to LON-CAPA's grading
74: interface, or other features they may wish to use in response to the
75: student's query.
76:
77: =item * B<Blocking>: LON-CAPA can block display of e-mails that are
78: sent to a student during an online exam. A course coordinator or
79: instructor can set an open and close date/time for scheduled online
80: exams in a course. If a user uses the LON-CAPA internal messaging
81: system to display e-mails during the scheduled blocking event,
82: display of all e-mail sent during the blocking period will be
83: suppressed, and a message of explanation, including details of the
84: currently active blocking periods will be displayed instead. A user
85: who has a course coordinator or instructor role in a course will be
86: unaffected by any blocking periods for the course, unless the user
87: also has a student role in the course, AND has selected the student role.
88:
89: =back
90:
91: Users can ask LON-CAPA to forward messages to conventional e-mail
92: addresses on their B<PREF> screen, but generally, LON-CAPA messages
93: are much more useful than traditional email can be made to be, even
94: with HTML support.
95:
96: Right now, this document will cover just how to send a message, since
97: it is likely you will not need to programmatically read messages,
98: since lonmsg already implements that functionality.
99:
100: The routines used to package messages and unpackage messages are not
101: only used by lonmsg when creating/extracting messages for LON-CAPA's
102: internal messaging system, but also by lonnotify.pm which is available
103: for use by Domain Coordinators to broadcast standard e-mail to specified
104: users in their domain. The XML packaging used in the two cases is very
105: similar. The differences are the use of <recuser>$uname</recuser> and
106: <recdomain>$udom</recdomain> in stored internal messages, compared
107: with <recipient username="$uname:$udom">$email</recipient> in stored
108: Domain Coordinator e-mail for the storage of information about
109: recipients of the message/e-mail.
