1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 3.1.1, unknown release date
13 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
14 handling of CSS-style lengths.
16 3.1.0, released 2008-05-18
17 # Unnecessary references to objects (vestiges of PHP4) removed from method
18 signatures. The following methods do not need references when assigning from
19 them and will result in E_STRICT errors if you try:
20 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
21 + HTMLPurifier_ConfigSchema::instance()
22 + HTMLPurifier_DefinitionCacheFactory::instance()
23 + HTMLPurifier_DefinitionCacheFactory->create()
24 + HTMLPurifier_DoctypeRegistry->register()
25 + HTMLPurifier_DoctypeRegistry->get()
26 + HTMLPurifier_HTMLModule->addElement()
27 + HTMLPurifier_HTMLModule->addBlankElement()
28 + HTMLPurifier_LanguageFactory::instance()
29 # Printer_ConfigForm's get*() functions were static-ified
30 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
31 form of tag@attr, NOT tag.attr (which will throw an error and won't do
32 anything). This is for forwards compatibility with XML; you'd do best
33 to migrate an %HTML.AllowedAttributes directives to this syntax too.
34 ! Allow index to be false for config from form creation
35 ! Added HTMLPurifier::VERSION constant
36 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
37 and allows for version numbers like "3.1.0-dev".
38 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
39 ! HTML Purifier's URI handling is a lot more robust, with much stricter
40 validation checks and better percent encoding handling.
41 ! Bootstrap autoloader deals more robustly with classes that don't exist,
42 preventing class_exists($class, true) from barfing.
43 - InterchangeBuilder now alphabetizes its lists
44 - Validation error in configdoc output fixed
45 - Iconv and other encoding errors muted even with custom error handlers that
46 do not honor error_reporting
47 - Add protection against imagecrash attack with CSS height/width
48 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
49 - Fixed and revamped broken ConfigForm smoketest
50 - Bug with bool/null fields in Printer_ConfigForm fixed
51 - Bug with global forbidden attributes fixed
52 - Improved error messages for allowed and forbidden HTML elements and attributes
53 - Missing (or null) in configdoc documentation restored
54 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
55 of DOM), HTML Purifier punts to DirectLex
56 - Fatal error with unserialization of ScriptRequired
57 - Created directories are now chmod'ed properly
58 - Fixed bug with fallback languages in LanguageFactory
59 - Standalone testing setup properly with autoload
60 . Out-of-date documentation revised
61 . UTF-8 encoding check optimization as suggested by Diego
62 . HTMLPurifier_Error removed in favor of exceptions
63 . More copy() function removed; should use clone instead
64 . More extensive unit tests for HTMLDefinition
65 . assertPurification moved to central harness
66 . HTMLPurifier_Generator accepts $config and $context parameters during
67 instantiation, not runtime
68 . Double-quotes outside of attribute values are now unescaped
70 3.1.0rc1, released 2008-04-22
71 # Autoload support added. Internal require_once's removed in favor of an
72 explicit require list or autoloading. To use HTML Purifier,
73 you must now either use HTMLPurifier.auto.php
74 or HTMLPurifier.includes.php; setting the include path and including
75 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
76 as well to register our autoload handler (or modify your autoload function
77 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
78 HTMLPurifier.safe-includes.php for a less performance friendly but more
79 user-friendly library load.
80 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
81 information is stored in the ConfigSchema directory, and the
82 maintenance/generate-schema-cache.php generates the schema.ser file, which
83 is now instantiated. Support for userland schema changes coming soon!
84 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
85 alias; to get rid of these errors just modify your configuration to use
86 the new directive name.
87 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
88 enabled using %Filter.$filter_name or by setting your own filters using
90 # Directive-level safety properties superceded in favor of module-level
91 safety. Internal method HTMLModule->addElement() has changed, although
92 the externally visible HTMLDefinition->addElement has *not* changed.
93 ! Extra utility classes for testing and non-library operations can
94 be found in extras/. Specifically, these are FSTools and ConfigDoc.
95 You may find a use for these in your own project, but right now they
96 are highly experimental and volatile.
97 ! Integration with PHPT allows for automated smoketests
98 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
99 by Chris. You can enable them with %HTML.Proprietary if your client
101 ! Support for !important CSS cascade modifier. By default, this will be stripped
102 from CSS, but you can enable it using %CSS.AllowImportant
103 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
105 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
106 Developer error (not enduser error) can cause these to be triggered.
107 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
108 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
109 mucking around with HTMLPurifier_CSSDefinition
110 ! ConfigDoc output has been enhanced with version and deprecation info.
111 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
112 - Autoclose now operates iteratively, i.e. <span><span><div> now has
113 both span tags closed.
114 - Various HTMLPurifier_Config convenience functions now accept another parameter
115 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
117 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
118 - Fix bug in ExtractStyleBlocks with comments in style tags
119 - Fix bug in comment parsing for DirectLex
120 - Flush output now displayed when in command line mode for unit tester
121 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
122 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
123 on the same element without emitting errors.
124 - Fixed fatal error in PH5P lexer with invalid tag names
125 . Plugins now get their own changelogs according to project conventions.
126 . Convert tokens to use instanceof, reducing memory footprint and
127 improving comparison speed.
128 . Dry runs now supported in SimpleTest; testing facilities improved
129 . Bootstrap class added for handling autoloading functionality
130 . Implemented recursive glob at FSTools->globr
131 . ConfigSchema now has instance methods for all corresponding define*
133 . A couple of new historical maintenance scripts were added.
134 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
135 . tests/index.php can now be run from any directory.
136 . HTMLPurifier_Token subclasses split into seperate files
137 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
138 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
139 . New --php=php flag added, allows PHP executable to be specified (command
141 . htmlpurifier_add_test() preferred method to translate test files in to
142 classes, because it handles PHPT files too.
143 . Debugger class is deprecated and will be removed soon.
144 . Command line argument parsing for testing scripts revamped, now --opt value
146 . Smoketests now cleanup after magic quotes
147 . Generator now can output comments (however, comments are still stripped
148 from HTML Purifier output)
149 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
150 HTMLPurifier_VarParser->parse()
151 . Integers auto-cast into float type by VarParser.
152 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
153 during cache generation
154 . Reordered script calls in maintenance/flush.php
155 . Command line scripts now honor exit codes
156 . When --flush fails in unit testers, abort tests and print message
157 . Improved documentation in docs/dev-flush.html about the maintenance scripts
158 . copy() methods removed in favor of clone keyword
160 3.0.0, released 2008-01-06
161 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
162 until PHP 4 is completely deprecated, but no new features will be added
164 + Visibility declarations added
165 + Constructor methods renamed to __construct()
166 + PHP4 reference cruft removed (in progress)
167 ! CSS properties are now case-insensitive

169 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
170 documents and cleaning their contents up. Requires the CSSTidy library
171 <http://csstidy.sourceforge.net/>. You can access the blocks with the
172 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
173 The output CSS can also be "scoped" for a specific element, use:
174 %Filter.ExtractStyleBlocksScope
175 ! Experimental support for some proprietary CSS attributes allowed:
176 opacity (and all of the browser-specific equivalents) and scrollbar colors.
177 Enable by setting %CSS.Proprietary to true.
178 - Colors missing # but in hex form will be corrected
179 - CSS Number algorithm improved
180 - Unit testing and multi-testing now on steroids: command lines,
181 XML output, and other goodies now added.
182 . Unit tests for Injector improved
184 + HTMLPurifier_AttrDef_CSS_AlphaValue
185 + HTMLPurifier_AttrDef_CSS_Filter
186 . Multitest now has a file docblock
188 2.1.3, released 2007-11-05
189 ! tests/multitest.php allows you to test multiple versions by running
190 tests/index.php through multiple interpreters using `phpv` shell
191 script (you must provide this script!)
192 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
194 - Injector algorithm further refined: off-by-one error regarding skip
195 counts for dormant injectors fixed
196 - Corrective blockquote definition now enabled for HTML 4.01 Strict
197 - Fatal error when <img> tag (or any other element with required attributes)
198 has 'id' attribute fixed, thanks NykO18 for reporting
199 - Fix warning emitted when a non-supported URI scheme is passed to the
200 MakeAbsolute URIFilter, thanks NykO18 (again)
201 - Further refine AutoParagraph injector. Behavior inside of elements
202 allowing paragraph tags clarified: only inline content delimeted by
203 double newlines (not block elements) are paragraphed.
204 - Buggy treatment of end tags of elements that have required attributes
205 fixed (does not manifest on default tag-set)
206 - Spurious internal content reorganization error suppressed
207 - HTMLDefinition->addElement now returns a reference to the created
208 element object, as implied by the documentation
209 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
210 - Fix a theoretical class of infinite loops from DirectLex reported
212 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
214 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
215 HTMLDefinition errors, this may indicate problems with error-collecting
217 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
218 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
219 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
220 to better communicate its purpose
221 . Error unit tests can now specify the expectation of no errors. Future
222 iterations of the harness will be extremely strict about what errors
224 . Extend Injector hooks to allow for more powerful injector routines
225 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
227 . Doxygen configuration file updated, with minor improvements
228 . Test runner now checks for similarly named files in conf/ directory too.
229 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
231 . Maintenance script for generating PH5P patch added, original PH5P source
232 file also added under version control
233 . Full unit test runner script title made more descriptive with PHP version
234 . Updated INSTALL file to state that 4.3.7 is the earliest version we
237 2.1.2, released 2007-09-03
238 ! Implemented Object module for trusted users
239 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
241 require_once 'HTMLPurifier/Lexer/PH5P.php';
242 $config->set('Core', 'LexerImpl', 'PH5P');
243 Note that this Lexer introduces some classes not in the HTMLPurifier
244 namespace. Also, this is PHP5 only.
245 ! CSS property border-spacing implemented
246 - Fix non-visible parsing error in DirectLex with empty tags that have
247 slashes inside attribute values.
248 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
249 accepted as valid CSS. Usually non-visible, because this styling is the
250 default for tables in most browsers. Thanks Brett Zamir for pointing
252 - Fix validation errors in configuration form
253 - Hammer out a bunch of edge-case bugs in the standalone distribution
254 - Inclusion reflection removed from URISchemeRegistry; you must manually
255 include any new schema files you wish to use
256 - Numerous typo fixes in documentation thanks to Brett Zamir
257 . Unit test refactoring for one logical test per test function
258 . Config and context parameters in ComplexHarness deprecated: instead, edit
259 the $config and $context member variables
260 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
261 really make a difference, but is good for completeness sake
262 . merge-library.php script refactored for greater code reusability and
265 2.1.1, released 2007-08-04
266 - Fix show-stopper bug in %URI.MakeAbsolute functionality
267 - Fix PHP4 syntax error in standalone version
268 . Add prefix directory to include path for standalone, this prevents
269 other installations from clobbering the standalone's URI schemes
270 . Single test methods can be invoked by prefixing with __only
272 2.1.0, released 2007-08-02
273 # flush-htmldefinition-cache.php superseded in favor of a generic
274 flush-definition-cache.php script, you can clear a specific cache
275 by passing its name as a parameter to the script
276 ! Phorum mod implemented for HTML Purifier
277 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
278 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
279 for PHP4 (DirectLex).
280 ! Standalone file now available, which greatly reduces the amount of
281 includes (although there are still a few files that reside in the
283 ! Relative URIs can now be transformed into their absolute equivalents
284 using %URI.Base and %URI.MakeAbsolute
285 ! Ruby implemented for XHTML 1.1
286 ! You can now define custom URI filtering behavior, see enduser-uri-filter.html

293 - XHTML 1.1 now applies XHTML 1.0 Strict cleanup routines, namely
295 - Contents of <style> tags removed by default when tags are removed
296 . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
297 for output cache invalidation
298 . ConfigForm printer now can retrieve CSS and JS files as strings, in
299 case HTML Purifier's directory is not publically accessible
300 . Introduce new text/itext configuration directive values: these represent
301 longer strings that would be more appropriately edited with a textarea
302 . Allow newlines to act as separators for lists, hashes, lookups and
304 . ConfigForm generates textareas instead of text inputs for lists, hashes,
305 lookups, text and itext fields
306 . Hidden element content removal genericized: %Core.HiddenElements can
307 be used to customize this behavior, by default <script> and <style> are
309 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
310 . Custom ChildDef added to default include list
311 . URIScheme reflection improved: will not attempt to include file if class
312 already exists. May clobber autoload, so I need to keep an eye on it
313 . ConfigSchema heavily optimized, will only collect information and validate
314 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
315 . AttrDef_URI unit tests and implementation refactored
316 . benchmarks/ directory now protected from public view with .htaccess file;
317 run the tests via command line
318 . URI scheme is munged off if there is no authority and the scheme is the
320 . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
321 . Interface for URIScheme changed
322 . Generic URI object to hold components of URI added, most systems involved
323 in URI validation have been migrated to use it
324 . Custom filtering for URIs factored out to URIDefinition interface for
325 maximum extensibility
327 2.0.1, released 2007-06-27
328 ! Tag auto-closing now based on a ChildDef heuristic rather than a
329 manually set auto_close array; some behavior may change
330 ! Experimental AutoFormat functionality added: auto-paragraph and
331 linkify your HTML input by setting %AutoFormat.AutoParagraph and
332 %AutoFormat.Linkify to true
333 ! Newlines normalized internally, and then converted back to the
334 value of PHP_EOL. If this is not desired, set your newline format
335 using %Output.Newline.
336 ! Beta error collection, messages are implemented for the most generic
337 cases involving Lexing or Strategies
338 - Clean up special case code for <script> tags
339 - Reorder includes for DefinitionCache decorators, fixes a possible
341 - Fixed bug where manually modified definitions were not saved via cache
342 (mostly harmless, except for the fact that it would be a little slower)
343 - Configuration objects with different serials do not clobber each
344 others when revision numbers are unequal
345 - Improve Serializer DefinitionCache directory permissions checks

353 . Rewire some test-cases to swallow errors rather than expect them
354 . HTMLDefinition printer updated with some of the new attributes
355 . DefinitionCache keys reordered to reflect precedence: version number,
356 hash, then revision number
357 . %Core.DefinitionCache renamed to %Cache.DefinitionImpl
358 . Interlinking in configuration documentation added using
359 Injector_PurifierLinkify
360 . Directives now keep track of aliases to themselves
361 . Error collector now requires a severity to be passed, use PHP's internal
362 error constants for this
363 . HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
364 much easier selective embedding of configuration values
365 . Doctype objects now accept public and system DTD identifiers
366 . %HTML.Doctype is now constrained by specific values, to specify a custom
367 doctype use new %HTML.CustomDoctype
368 . ConfigForm truncates long directives to keep the form small, and does
369 not re-output namespaces
371 2.0.0, released 2007-06-20
372 # Completely refactored HTMLModuleManager, decentralizing safety
374 # Transform modules changed to Tidy modules, which offer more flexibility
375 and better modularization
376 # Configuration object now finalizes itself when a read operation is
377 performed on it, ensuring that its internal state stays consistent.
378 To revert this behavior, you can set the $autoFinalize member variable
379 off, but it's not recommended.
380 # New compact syntax for AttrDef objects that can be used to instantiate
381 new objects via make()
382 # Definitions (esp. HTMLDefinition) are now cached for a significant
383 performance boost. You can disable caching by setting %Core.DefinitionCache
384 to null. You CANNOT edit raw definitions without setting the corresponding
385 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
386 # Contents between <script> tags are now completely removed if <script>
388 # Prototype-declarations for Lexer removed in favor of configuration
389 determination of Lexer implementations.

408 - Bug resulting from tag transforms to non-allowed elements fixed
409 - ChildDef_Custom's regex generation has been improved, removing several
411 . Unit test for ElementDef created, ElementDef behavior modified to
413 . Added convenience functions for HTMLModule constructors
414 . AttrTypes now has accessor functions that should be used instead
415 of directly manipulating info
416 . TagTransform_Center deprecated in favor of generic TagTransform_Simple

440 images will hang around with an empty src
441 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
443 ! CSS property white-space now allows nowrap (supported in all modern
444 browsers) but not others (which have spotty browser implementations)
445 ! XHTML 1.1 mode now sort-of works without any fatal errors, and
446 lang is now moved over to xml:lang.
447 ! Attribute transformation smoketest available at smoketests/attrTransform.php
448 ! Transformation of font's size attribute now handles super-large numbers
449 - Possibly fatal bug with __autoload() fixed in module manager
450 - Invert HTMLModuleManager->addModule() processing order to check

474 %Attr.IDBlacklistRegexp
475 - Error messages are emitted when you attempt to "allow" elements or
476 attributes that HTML Purifier does not support
477 - Fix segfault in unit test. The problem is not very reproduceable and
478 I don't know what causes it, but a six line patch fixed it.
480 1.5.0, released 2007-03-23
481 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
482 doesn't actually do anything yet, but keep your eyes peeled.
483 ! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
484 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.

505 . Modify Youtube filter regexp to be multiline
506 . Require both PHP5 and DOM extension in order to use DOMLex, fixes
