NEWS ( CHANGELOG and HISTORY ) HTMLPurifier ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| = KEY ==================== # Breaks back-compat ! Feature - Bugfix + Sub-comment . Internal change ========================== 3.1.0, released 2008-05-18 # Unnecessary references to objects (vestiges of PHP4) removed from method signatures. The following methods do not need references when assigning from them and will result in E_STRICT errors if you try: + HTMLPurifier_Config->get*Definition() [* = HTML, CSS] + HTMLPurifier_ConfigSchema::instance() + HTMLPurifier_DefinitionCacheFactory::instance() + HTMLPurifier_DefinitionCacheFactory->create() + HTMLPurifier_DoctypeRegistry->register() + HTMLPurifier_DoctypeRegistry->get() + HTMLPurifier_HTMLModule->addElement() + HTMLPurifier_HTMLModule->addBlankElement() + HTMLPurifier_LanguageFactory::instance() # Printer_ConfigForm's get*() functions were static-ified # %HTML.ForbiddenAttributes requires attribute declarations to be in the form of tag@attr, NOT tag.attr (which will throw an error and won't do anything). This is for forwards compatibility with XML; you'd do best to migrate an %HTML.AllowedAttributes directives to this syntax too. ! Allow index to be false for config from form creation ! Added HTMLPurifier::VERSION constant ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible and allows for version numbers like "3.1.0-dev". ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime! ! HTML Purifier's URI handling is a lot more robust, with much stricter validation checks and better percent encoding handling. ! Bootstrap autoloader deals more robustly with classes that don't exist, preventing class_exists($class, true) from barfing. - InterchangeBuilder now alphabetizes its lists - Validation error in configdoc output fixed - Iconv and other encoding errors muted even with custom error handlers that do not honor error_reporting - Add protection against imagecrash attack with CSS height/width - HTMLPurifier::instance() created for consistency, is equivalent to getInstance() - Fixed and revamped broken ConfigForm smoketest - Bug with bool/null fields in Printer_ConfigForm fixed - Bug with global forbidden attributes fixed - Improved error messages for allowed and forbidden HTML elements and attributes - Missing (or null) in configdoc documentation restored - If DOM throws and exception during parsing with PH5P (occurs in newer versions of DOM), HTML Purifier punts to DirectLex - Fatal error with unserialization of ScriptRequired - Created directories are now chmod'ed properly - Fixed bug with fallback languages in LanguageFactory - Standalone testing setup properly with autoload . Out-of-date documentation revised . UTF-8 encoding check optimization as suggested by Diego . HTMLPurifier_Error removed in favor of exceptions . More copy() function removed; should use clone instead . More extensive unit tests for HTMLDefinition . assertPurification moved to central harness . HTMLPurifier_Generator accepts $config and $context parameters during instantiation, not runtime . Double-quotes outside of attribute values are now unescaped 3.1.0rc1, released 2008-04-22 # Autoload support added. Internal require_once's removed in favor of an explicit require list or autoloading. To use HTML Purifier, you must now either use HTMLPurifier.auto.php or HTMLPurifier.includes.php; setting the include path and including HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php as well to register our autoload handler (or modify your autoload function to check HTMLPurifier_Bootstrap::getPath($class)). You can also use HTMLPurifier.safe-includes.php for a less performance friendly but more user-friendly library load. # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema information is stored in the ConfigSchema directory, and the maintenance/generate-schema-cache.php generates the schema.ser file, which is now instantiated. Support for userland schema changes coming soon! # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive alias; to get rid of these errors just modify your configuration to use the new directive name. # HTMLPurifier->addFilter is deprecated; built-in filters can now be enabled using %Filter.$filter_name or by setting your own filters using %Filter.Custom # Directive-level safety properties superceded in favor of module-level safety. Internal method HTMLModule->addElement() has changed, although the externally visible HTMLDefinition->addElement has *not* changed. ! Extra utility classes for testing and non-library operations can be found in extras/. Specifically, these are FSTools and ConfigDoc. You may find a use for these in your own project, but right now they are highly experimental and volatile. ! Integration with PHPT allows for automated smoketests ! Limited support for proprietary HTML elements, namely , sponsored by Chris. You can enable them with %HTML.Proprietary if your client demands them. ! Support for !important CSS cascade modifier. By default, this will be stripped from CSS, but you can enable it using %CSS.AllowImportant ! Support for display and visibility CSS properties added, set %CSS.AllowTricky to true to use them. ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception. Developer error (not enduser error) can cause these to be triggered. ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without mucking around with HTMLPurifier_CSSDefinition ! ConfigDoc output has been enhanced with version and deprecation info. ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented. - Autoclose now operates iteratively, i.e.
now has both span tags closed. - Various HTMLPurifier_Config convenience functions now accept another parameter $schema which defines what HTMLPurifier_ConfigSchema to use besides the global default. - Fix bug with trusted script handling in libxml versions later than 2.6.28. - Fix bug in ExtractStyleBlocks with comments in style tags - Fix bug in comment parsing for DirectLex - Flush output now displayed when in command line mode for unit tester - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times on the same element without emitting errors. - Fixed fatal error in PH5P lexer with invalid tag names . Plugins now get their own changelogs according to project conventions. . Convert tokens to use instanceof, reducing memory footprint and improving comparison speed. . Dry runs now supported in SimpleTest; testing facilities improved . Bootstrap class added for handling autoloading functionality . Implemented recursive glob at FSTools->globr . ConfigSchema now has instance methods for all corresponding define* static methods. . A couple of new historical maintenance scripts were added. . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files . tests/index.php can now be run from any directory. . HTMLPurifier_Token subclasses split into seperate files . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier . New --php=php flag added, allows PHP executable to be specified (command line only!) . htmlpurifier_add_test() preferred method to translate test files in to classes, because it handles PHPT files too. . Debugger class is deprecated and will be removed soon. . Command line argument parsing for testing scripts revamped, now --opt value format is supported. . Smoketests now cleanup after magic quotes . Generator now can output comments (however, comments are still stripped from HTML Purifier output) . HTMLPurifier_ConfigSchema->validate() deprecated in favor of HTMLPurifier_VarParser->parse() . Integers auto-cast into float type by VarParser. . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only during cache generation . Reordered script calls in maintenance/flush.php . Command line scripts now honor exit codes . When --flush fails in unit testers, abort tests and print message . Improved documentation in docs/dev-flush.html about the maintenance scripts . copy() methods removed in favor of clone keyword 3.0.0, released 2008-01-06 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained until PHP 4 is completely deprecated, but no new features will be added to it. + Visibility declarations added + Constructor methods renamed to __construct() + PHP4 reference cruft removed (in progress) ! CSS properties are now case-insensitive ! DefinitionCacheFactory now can register new implementations ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting
