Version 1.2.x History

DSig Reference Code Version History

• New method setRating added to Label.
• IsoDate moved from package w3c.tools.util to w3c.pics.parser. The PICS library now contains classes only in w3c.pics.parser.
• Completely rewritten LabelFinder, by the creators of the PICS Robot Label Grabber.

• Fixed a bug in the ProfileParser when reading URLs containing %*
• Fixed a bug in the ProfileParser that caused the hostnames within URLs to be evaluated improperly.
• Updated ProfileParser to be in synch with PICSRules spec dated December 29 1997.
• Fixed a bug that occured when cloning Profiles.
• Policy was made a public class. Several of its methods were also made public.
• Removed the quotes that surrounded rating service and rating system URLs inside Service objects. Quotes still appear properly when toString() is called.
• New method writeSQLQuery() added to Policy.
• New method getFullServiceName() added to Profile.
• New method toCommaDelimString() added to Rating.
• Fixed a bug in Label that caused quotes to appear in generic clauses. Generic clauses should not have quotes around their boolean values.
• Updated all parsers to use JavaCC 0.7
  NOTE:These parsers will no longer function properly under versions of JavaCC prior to 0.7

• Fixed a bug in Policy that caused crashes when using the Filter command on a page that did not have any labels.
• New method clone() added to Profile.

• Updated ProfileParser to be in synch with PICSRules spec dated October 22 1997.
• New class ProfileDecoder: This class can be used to decode the hex-encodings that are found within strings in a PICSRule.
• ParseError was changed to make certain types of error messages more informative.
• Fixed the ProfileParser so that it correctly handles the case-insensitivity of attribute names.

• Updated ProfileParser to be in synch with PICSRules spec dated October 9 1997.
• Supports evaluation of a profile against multiple labels at a time. This allows labels for multiple services for the same page to be submitted to a Profile all at the same time, as per the PICSRules specification.
• New commands in PICSParser: Find Labels and Filter. See the documentation page for details.
• New class LabelFinder: This class is used to locate labels in the headers of HTML files.
• The LabelParser now attempts to parse PICS1.0 labels as PICS1.1 labels rather than automatically failing. If the PICS1.0 label actually has valid PICS1.1 syntax, it will parse correctly.
• In debugmode, profile evaluation now prints out the Explanation sub-clause of the Policy that activated.
• New method isValidWithReason() added to Profile.

Version 1.0.x History

• The bugfix from version 1.0.7 did not work properly. It fixed some cases of the servicename.categoryname bug, but broke other parts of the label/profile evaluator. This version should fix any lingering problems in the evaluator.

• Fixed a bug in Label.toDsigString() that caused extra spaces to appear.
• New method getServiceNames() added to Profile.
• Fixed a bug in label/profile evaluation in which the Profile mistakenly only used the categoryname to determine whether a label's category matched a particular expression, rather than using the full servicename.categoryname.

• Updated ProfileParser to be in synch with PICSRules spec dated September 22 1997.

• Fixed a bug in Profile that caused crashes when evaluating profiles that contained no Policy clauses. A Profile without Policy clauses should always return true.

• Fixed a bug in Label regarding multivalued categories. Parens were accidentally being omitted.
• Fixed a bug in Rating. Range-style ratings were being incorrectly initialized. The high end of the range was correct, but the low end of the range was being left empty.
• Fixed a bug in Profile parsing/evaluation with simple expressions that use the '=' operator. They had not been working correctly.

• All objects in the library are now serializable as per the Java 1.1 Object Serialization Specification.
• New method getFullName() added to Category.
• New methods getName() and getValue() added to Enum.
• Shorter error messages. No more nearly-infinite error messages on parse errors.

• Updated ProfileParser to be in synch with PICSRules spec dated August 28 1997.

• Updated ProfileParser to be in synch with PICSRules spec dated August 22 1997.
• RejectByURL and AcceptByURL Policy clauses now evaluate correctly when the URLs do not match any known internet scheme.
• Many classes that were public in version 1.0.0 now have package access only.
• Extensions in profiles now parse correctly.
