CHANGELOG

@ -1,6 +1,56 @@
2009-08-21 Reiner Jung <reiner@kb-m.com>

NEW FEATURES:

- Community-ID news feed has been moved to a new About section, visible
only by admins.
- News in the home page are now manageable by the admin.
- Brute-force login attempts are now mitigated through the appearance of
a captcha after the third failed attempt, in both the main page login
section, and when trying to log-in while during an OpenID authentication.
- Removed requirement of having short_open_tag php.ini directive to be On.
- The user's OpenID URL is now visible in all pages when he's logged in.
- The Manage Users section now has a search field.
- You're able to delete unconfirmed users that have not confirmed their
account for a given number of days.
- You're able to send a reminder to unconfirmed users that have not
confirmed their account for a given number of days.
- Added sorting ability for the History Log table. Have it sort from
latest to oldest by default.
- Replaced rich-text editor in the Message Users section with the more
capable FCK Editor.
- Rich-text editor messages are filtered through the HTMLPurifier lib,
that filters out XSS and other malignous content.
- Upgraded Zend Framework to version 1.8.4PL1


FIXED BUGS:

- Fixed compatibility with OpenID relays that send their info through
POST instead of GET.
- Fixed support for relays not sending the OpenID identifier. This fixes
Facebook compatibility.
- Fixed clashes with other Zend Frameworks located in PHP's include path.
- Now only ascii characters will be allowed in the usernames, to avoid
problems in the OpenID URL.
- Fixed pagination issues in the Manage Users section.
- Fixed pagination issues in the History Log section.
- Fixed problems in the Feedback and Message Users forms.
- Mass-mailing to users will have the recipients in BCC instead of TO,
to avoid revealing E-mails to all recipients.
- Fixed layout issue of the login checkbox "Remember me", under IE and
Opera.
- Fixed some javascript error messages under IE.


NEW REQUIREMENTS:

- Minimal supported PHP version is 5.2.4

* A session negotiator controls the allowed and preferred association
* types and association session types. Both the {@link
* Auth_OpenID_Consumer} and {@link Auth_OpenID_Server} use
* negotiators when creating associations.
*
* You can create and use negotiators if you:

* - Do not want to do Diffie-Hellman key exchange because you use
* transport-layer encryption (e.g. SSL)
*
* - Want to use only SHA-256 associations
*
* - Do not want to support plain-text associations over a non-secure
* channel
*
* It is up to you to set a policy for what kinds of associations to
* accept. By default, the library will make any kind of association
* that is allowed in the OpenID 2.0 specification.
*
* Use of negotiators in the library
* =================================
*
* When a consumer makes an association request, it calls {@link
* getAllowedType} to get the preferred association type and
* association session type.
*
* The server gets a request for a particular association/session type
* and calls {@link isAllowed} to determine if it should create an
* association. If it is supported, negotiation is complete. If it is
* not, the server calls {@link getAllowedType} to get an allowed
* association type to return to the consumer.
*
* If the consumer gets an error response indicating that the
* requested association/session type is not supported by the server
* that contains an assocation/session type to try, it calls {@link
* isAllowed} to determine if it should try again with the given
* combination of association/session type.

<?php

/**
* This module implements a VERY limited parser that finds <link> tags
* in the head of HTML or XHTML documents and parses out their
* attributes according to the OpenID spec. It is a liberal parser,
* but it requires these things from the data in order to work:
*
* - There must be an open <html> tag
*
* - There must be an open <head> tag inside of the <html> tag
*
* - Only <link>s that are found inside of the <head> tag are parsed
* (this is by design)
*
* - The parser follows the OpenID specification in resolving the
* attributes of the link tags. This means that the attributes DO
* NOT get resolved as they would by an XML or HTML parser. In
* particular, only certain entities get replaced, and href
* attributes do not get resolved relative to a base URL.
*
* From http://openid.net/specs.bml:
*
* - The openid.server URL MUST be an absolute URL. OpenID consumers
* MUST NOT attempt to resolve relative URLs.
*
* - The openid.server URL MUST NOT include entities other than &amp;,
* &lt;, &gt;, and &quot;.
*
* The parser ignores SGML comments and <![CDATA[blocks]]>. Both kinds
* of quoting are allowed for attributes.
*
* The parser deals with invalid markup in these ways:
*
* - Tag names are not case-sensitive
*
* - The <html> tag is accepted even when it is not at the top level
*
* - The <head> tag is accepted even when it is not a direct child of
* the <html> tag, but a <html> tag must be an ancestor of the
* <head> tag
*
* - <link> tags are accepted even when they are not direct children
* of the <head> tag, but a <head> tag must be an ancestor of the
* <link> tag
*
* - If there is no closing tag for an open <html> or <head> tag, the
* remainder of the document is viewed as being inside of the
* tag. If there is no closing tag for a <link> tag, the link tag is
* treated as a short tag. Exceptions to this rule are that <html>
* closes <html> and <body> or <head> closes <head>
*
* - Attributes of the <link> tag are not required to be quoted.
*
* - In the case of duplicated attribute names, the attribute coming
* last in the tag will be the value returned.
*
* - Any text that does not parse as an attribute within a link tag
* will be ignored. (e.g. <link pumpkin rel='openid.server' /> will
* ignore pumpkin)
*
* - If there are more than one <html> or <head> tag, the parser only
* looks inside of the first one.
*
* - The contents of <script> tags are ignored entirely, except
* unclosed <script> tags. Unclosed <script> tags are ignored.
*
* - Any other invalid markup is ignored, including unclosed SGML
* comments and unclosed <![CDATA[blocks.

/**
* This is the core of the PHP Yadis library. This is the only class
* a user needs to use to perform Yadis discovery. This class
* performs the discovery AND stores the result of the discovery.
*
* First, require this library into your program source:
*
* <pre> require_once "Auth/Yadis/Yadis.php";</pre>
*
* To perform Yadis discovery, first call the "discover" method
* statically with a URI parameter:
*
* <pre> $http_response = array();
* $fetcher = Auth_Yadis_Yadis::getHTTPFetcher();
* $yadis_object = Auth_Yadis_Yadis::discover($uri,
* $http_response, $fetcher);</pre>
*
* If the discovery succeeds, $yadis_object will be an instance of
* {@link Auth_Yadis_Yadis}. If not, it will be null. The XRDS
* document found during discovery should have service descriptions,
* which can be accessed by calling
*
* <pre> $service_list = $yadis_object->services();</pre>
*
* which returns an array of objects which describe each service.
* These objects are instances of Auth_Yadis_Service. Each object
* describes exactly one whole Service element, complete with all of
* its Types and URIs (no expansion is performed). The common use
* case for using the service objects returned by services() is to
* write one or more filter functions and pass those to services():
*
* <pre> $service_list = $yadis_object->services(
* array("filterByURI",
* "filterByExtension"));</pre>
*
* The filter functions (whose names appear in the array passed to
* services()) take the following form:
*
* <pre> function myFilter(&$service) {
* // Query $service object here. Return true if the service
* // matches your query; false if not.
* }</pre>
*
* This is an example of a filter which uses a regular expression to
* match the content of URI tags (note that the Auth_Yadis_Service
* class provides a getURIs() method which you should use instead of
* this contrived example):
*
* <pre>
* function URIMatcher(&$service) {
* foreach ($service->getElements('xrd:URI') as $uri) {
* if (preg_match("/some_pattern/",
* $service->parser->content($uri))) {
* return true;
* }
* }
* return false;
* }</pre>
*
* The filter functions you pass will be called for each service
* object to determine which ones match the criteria your filters
* specify. The default behavior is that if a given service object
* matches ANY of the filters specified in the services() call, it
* will be returned. You can specify that a given service object will
* be returned ONLY if it matches ALL specified filters by changing
* the match mode of services():
*
* <pre> $yadis_object->services(array("filter1", "filter2"),
* SERVICES_YADIS_MATCH_ALL);</pre>
*
* See {@link SERVICES_YADIS_MATCH_ALL} and {@link
* SERVICES_YADIS_MATCH_ANY}.
*
* Services described in an XRDS should have a library which you'll
* probably be using. Those libraries are responsible for defining
* filters that can be used with the "services()" call. If you need
* to write your own filter, see the documentation for {@link
* Auth_Yadis_Service}.
