1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 3.1.1, unknown release date
13 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
14 and height/width HTML with %HTML.MaxImgLength.
15 - Disable percent height/width attributes for img
16 - AttrValidator operations are now atomic; updates to attributes are not
17 manifest in token until end of operations. This prevents naughty internal
18 code from directly modifying CurrentToken when they're not supposed to.
19 - Percent encoding checks enabled for URI query and fragment
20 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
21 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
23 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
24 to __construct($min, $max). __construct(true) is equivalent to
26 . Added HTMLPurifier_AttrDef_Switch class
27 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
28 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
29 get this called with the configuration object. All modules now
30 use this rather than __construct(), although legacy code using constructors
31 will still work--the new format, however, lets modules access the
32 configuration object for HTML namespace dependant tweaks.
33 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
34 . ConfigSchema data-structure heavily optimized; on average it uses half
35 the memory it did previously. The interface has changed accordingly,
36 consult changes to HTMLPurifier_Config for details.
37 . Variable parsing types now are magic integers instead of strings
38 . Added benchmark for ConfigSchema
41 3.1.0, released 2008-05-18
42 # Unnecessary references to objects (vestiges of PHP4) removed from method
43 signatures. The following methods do not need references when assigning from
44 them and will result in E_STRICT errors if you try:
45 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
46 + HTMLPurifier_ConfigSchema::instance()
47 + HTMLPurifier_DefinitionCacheFactory::instance()
48 + HTMLPurifier_DefinitionCacheFactory->create()
49 + HTMLPurifier_DoctypeRegistry->register()
50 + HTMLPurifier_DoctypeRegistry->get()
51 + HTMLPurifier_HTMLModule->addElement()
52 + HTMLPurifier_HTMLModule->addBlankElement()
53 + HTMLPurifier_LanguageFactory::instance()
54 # Printer_ConfigForm's get*() functions were static-ified
55 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
56 form of tag@attr, NOT tag.attr (which will throw an error and won't do
57 anything). This is for forwards compatibility with XML; you'd do best
58 to migrate an %HTML.AllowedAttributes directives to this syntax too.
59 ! Allow index to be false for config from form creation
60 ! Added HTMLPurifier::VERSION constant
61 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
62 and allows for version numbers like "3.1.0-dev".
63 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
64 ! HTML Purifier's URI handling is a lot more robust, with much stricter
65 validation checks and better percent encoding handling.
66 ! Bootstrap autoloader deals more robustly with classes that don't exist,
67 preventing class_exists($class, true) from barfing.
68 - InterchangeBuilder now alphabetizes its lists
69 - Validation error in configdoc output fixed
70 - Iconv and other encoding errors muted even with custom error handlers that
71 do not honor error_reporting
72 - Add protection against imagecrash attack with CSS height/width
73 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
74 - Fixed and revamped broken ConfigForm smoketest
75 - Bug with bool/null fields in Printer_ConfigForm fixed
76 - Bug with global forbidden attributes fixed
77 - Improved error messages for allowed and forbidden HTML elements and attributes
78 - Missing (or null) in configdoc documentation restored
79 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
80 of DOM), HTML Purifier punts to DirectLex
81 - Fatal error with unserialization of ScriptRequired
82 - Created directories are now chmod'ed properly
83 - Fixed bug with fallback languages in LanguageFactory
84 - Standalone testing setup properly with autoload
85 . Out-of-date documentation revised
86 . UTF-8 encoding check optimization as suggested by Diego
87 . HTMLPurifier_Error removed in favor of exceptions
88 . More copy() function removed; should use clone instead
89 . More extensive unit tests for HTMLDefinition
90 . assertPurification moved to central harness
91 . HTMLPurifier_Generator accepts $config and $context parameters during
92 instantiation, not runtime
93 . Double-quotes outside of attribute values are now unescaped
95 3.1.0rc1, released 2008-04-22
96 # Autoload support added. Internal require_once's removed in favor of an
97 explicit require list or autoloading. To use HTML Purifier,
98 you must now either use HTMLPurifier.auto.php
99 or HTMLPurifier.includes.php; setting the include path and including
100 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
101 as well to register our autoload handler (or modify your autoload function
102 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
103 HTMLPurifier.safe-includes.php for a less performance friendly but more
104 user-friendly library load.
105 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
106 information is stored in the ConfigSchema directory, and the
107 maintenance/generate-schema-cache.php generates the schema.ser file, which
108 is now instantiated. Support for userland schema changes coming soon!
109 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
110 alias; to get rid of these errors just modify your configuration to use
111 the new directive name.
112 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
113 enabled using %Filter.$filter_name or by setting your own filters using
115 # Directive-level safety properties superceded in favor of module-level
116 safety. Internal method HTMLModule->addElement() has changed, although
117 the externally visible HTMLDefinition->addElement has *not* changed.
118 ! Extra utility classes for testing and non-library operations can
119 be found in extras/. Specifically, these are FSTools and ConfigDoc.
120 You may find a use for these in your own project, but right now they
121 are highly experimental and volatile.
122 ! Integration with PHPT allows for automated smoketests
123 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
124 by Chris. You can enable them with %HTML.Proprietary if your client
126 ! Support for !important CSS cascade modifier. By default, this will be stripped
127 from CSS, but you can enable it using %CSS.AllowImportant
128 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
130 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
131 Developer error (not enduser error) can cause these to be triggered.
132 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
133 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
134 mucking around with HTMLPurifier_CSSDefinition
135 ! ConfigDoc output has been enhanced with version and deprecation info.
136 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
137 - Autoclose now operates iteratively, i.e. <span><span><div> now has
138 both span tags closed.
139 - Various HTMLPurifier_Config convenience functions now accept another parameter
140 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
142 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
143 - Fix bug in ExtractStyleBlocks with comments in style tags
144 - Fix bug in comment parsing for DirectLex
145 - Flush output now displayed when in command line mode for unit tester
146 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
147 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
148 on the same element without emitting errors.
149 - Fixed fatal error in PH5P lexer with invalid tag names
150 . Plugins now get their own changelogs according to project conventions.
151 . Convert tokens to use instanceof, reducing memory footprint and
152 improving comparison speed.
153 . Dry runs now supported in SimpleTest; testing facilities improved
154 . Bootstrap class added for handling autoloading functionality
155 . Implemented recursive glob at FSTools->globr
156 . ConfigSchema now has instance methods for all corresponding define*
158 . A couple of new historical maintenance scripts were added.
159 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
160 . tests/index.php can now be run from any directory.
161 . HTMLPurifier_Token subclasses split into seperate files
162 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
163 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
164 . New --php=php flag added, allows PHP executable to be specified (command
166 . htmlpurifier_add_test() preferred method to translate test files in to
167 classes, because it handles PHPT files too.
168 . Debugger class is deprecated and will be removed soon.
169 . Command line argument parsing for testing scripts revamped, now --opt value
171 . Smoketests now cleanup after magic quotes
172 . Generator now can output comments (however, comments are still stripped
173 from HTML Purifier output)
174 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
175 HTMLPurifier_VarParser->parse()
176 . Integers auto-cast into float type by VarParser.
177 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
178 during cache generation
179 . Reordered script calls in maintenance/flush.php
180 . Command line scripts now honor exit codes
181 . When --flush fails in unit testers, abort tests and print message
182 . Improved documentation in docs/dev-flush.html about the maintenance scripts
183 . copy() methods removed in favor of clone keyword
185 3.0.0, released 2008-01-06
186 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
187 until PHP 4 is completely deprecated, but no new features will be added
189 + Visibility declarations added
190 + Constructor methods renamed to __construct()
191 + PHP4 reference cruft removed (in progress)
192 ! CSS properties are now case-insensitive
193 ! DefinitionCacheFactory now can register new implementations
194 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
195 documents and cleaning their contents up. Requires the CSSTidy library
196 <http://csstidy.sourceforge.net/>. You can access the blocks with the
197 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
198 The output CSS can also be "scoped" for a specific element, use:
199 %Filter.ExtractStyleBlocksScope
200 ! Experimental support for some proprietary CSS attributes allowed:
201 opacity (and all of the browser-specific equivalents) and scrollbar colors.
202 Enable by setting %CSS.Proprietary to true.
203 - Colors missing # but in hex form will be corrected
204 - CSS Number algorithm improved
205 - Unit testing and multi-testing now on steroids: command lines,
206 XML output, and other goodies now added.
207 . Unit tests for Injector improved
209 + HTMLPurifier_AttrDef_CSS_AlphaValue
210 + HTMLPurifier_AttrDef_CSS_Filter
211 . Multitest now has a file docblock
213 2.1.3, released 2007-11-05
214 ! tests/multitest.php allows you to test multiple versions by running
215 tests/index.php through multiple interpreters using `phpv` shell
216 script (you must provide this script!)
217 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
219 - Injector algorithm further refined: off-by-one error regarding skip
220 counts for dormant injectors fixed
221 - Corrective blockquote definition now enabled for HTML 4.01 Strict
222 - Fatal error when <img> tag (or any other element with required attributes)
223 has 'id' attribute fixed, thanks NykO18 for reporting
224 - Fix warning emitted when a non-supported URI scheme is passed to the
225 MakeAbsolute URIFilter, thanks NykO18 (again)
226 - Further refine AutoParagraph injector. Behavior inside of elements
227 allowing paragraph tags clarified: only inline content delimeted by
228 double newlines (not block elements) are paragraphed.
229 - Buggy treatment of end tags of elements that have required attributes
230 fixed (does not manifest on default tag-set)
231 - Spurious internal content reorganization error suppressed
232 - HTMLDefinition->addElement now returns a reference to the created
233 element object, as implied by the documentation
234 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
235 - Fix a theoretical class of infinite loops from DirectLex reported
237 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
239 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
240 HTMLDefinition errors, this may indicate problems with error-collecting
242 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
243 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
244 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
245 to better communicate its purpose
246 . Error unit tests can now specify the expectation of no errors. Future
247 iterations of the harness will be extremely strict about what errors
249 . Extend Injector hooks to allow for more powerful injector routines
250 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
252 . Doxygen configuration file updated, with minor improvements
253 . Test runner now checks for similarly named files in conf/ directory too.
254 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
256 . Maintenance script for generating PH5P patch added, original PH5P source
257 file also added under version control
258 . Full unit test runner script title made more descriptive with PHP version
259 . Updated INSTALL file to state that 4.3.7 is the earliest version we
262 2.1.2, released 2007-09-03
263 ! Implemented Object module for trusted users
264 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
266 require_once 'HTMLPurifier/Lexer/PH5P.php';
267 $config->set('Core', 'LexerImpl', 'PH5P');
268 Note that this Lexer introduces some classes not in the HTMLPurifier
269 namespace. Also, this is PHP5 only.
270 ! CSS property border-spacing implemented
271 - Fix non-visible parsing error in DirectLex with empty tags that have
272 slashes inside attribute values.
273 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
274 accepted as valid CSS. Usually non-visible, because this styling is the
275 default for tables in most browsers. Thanks Brett Zamir for pointing
277 - Fix validation errors in configuration form
278 - Hammer out a bunch of edge-case bugs in the standalone distribution
279 - Inclusion reflection removed from URISchemeRegistry; you must manually
280 include any new schema files you wish to use
281 - Numerous typo fixes in documentation thanks to Brett Zamir
282 . Unit test refactoring for one logical test per test function
283 . Config and context parameters in ComplexHarness deprecated: instead, edit
284 the $config and $context member variables
285 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
286 really make a difference, but is good for completeness sake
287 . merge-library.php script refactored for greater code reusability and
290 2.1.1, released 2007-08-04
291 - Fix show-stopper bug in %URI.MakeAbsolute functionality
292 - Fix PHP4 syntax error in standalone version
293 . Add prefix directory to include path for standalone, this prevents
294 other installations from clobbering the standalone's URI schemes
295 . Single test methods can be invoked by prefixing with __only
297 2.1.0, released 2007-08-02
298 # flush-htmldefinition-cache.php superseded in favor of a generic
299 flush-definition-cache.php script, you can clear a specific cache
300 by passing its name as a parameter to the script
301 ! Phorum mod implemented for HTML Purifier
302 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
303 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
304 for PHP4 (DirectLex).
305 ! Standalone file now available, which greatly reduces the amount of
306 includes (although there are still a few files that reside in the
308 ! Relative URIs can now be transformed into their absolute equivalents
309 using %URI.Base and %URI.MakeAbsolute
310 ! Ruby implemented for XHTML 1.1
311 ! You can now define custom URI filtering behavior, see enduser-uri-filter.html

318 - XHTML 1.1 now applies XHTML 1.0 Strict cleanup routines, namely
320 - Contents of <style> tags removed by default when tags are removed
321 . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
322 for output cache invalidation
323 . ConfigForm printer now can retrieve CSS and JS files as strings, in
324 case HTML Purifier's directory is not publically accessible
325 . Introduce new text/itext configuration directive values: these represent
326 longer strings that would be more appropriately edited with a textarea
327 . Allow newlines to act as separators for lists, hashes, lookups and
329 . ConfigForm generates textareas instead of text inputs for lists, hashes,
330 lookups, text and itext fields
331 . Hidden element content removal genericized: %Core.HiddenElements can
332 be used to customize this behavior, by default <script> and <style> are
334 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
335 . Custom ChildDef added to default include list
336 . URIScheme reflection improved: will not attempt to include file if class
337 already exists. May clobber autoload, so I need to keep an eye on it
338 . ConfigSchema heavily optimized, will only collect information and validate
339 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
340 . AttrDef_URI unit tests and implementation refactored
341 . benchmarks/ directory now protected from public view with .htaccess file;
342 run the tests via command line
343 . URI scheme is munged off if there is no authority and the scheme is the
345 . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
346 . Interface for URIScheme changed
347 . Generic URI object to hold components of URI added, most systems involved
348 in URI validation have been migrated to use it
349 . Custom filtering for URIs factored out to URIDefinition interface for
350 maximum extensibility
352 2.0.1, released 2007-06-27
353 ! Tag auto-closing now based on a ChildDef heuristic rather than a
354 manually set auto_close array; some behavior may change
355 ! Experimental AutoFormat functionality added: auto-paragraph and
356 linkify your HTML input by setting %AutoFormat.AutoParagraph and
357 %AutoFormat.Linkify to true
358 ! Newlines normalized internally, and then converted back to the
359 value of PHP_EOL. If this is not desired, set your newline format
360 using %Output.Newline.
361 ! Beta error collection, messages are implemented for the most generic
362 cases involving Lexing or Strategies
363 - Clean up special case code for <script> tags
364 - Reorder includes for DefinitionCache decorators, fixes a possible
366 - Fixed bug where manually modified definitions were not saved via cache
367 (mostly harmless, except for the fact that it would be a little slower)
368 - Configuration objects with different serials do not clobber each
369 others when revision numbers are unequal
370 - Improve Serializer DefinitionCache directory permissions checks
371 - DefinitionCache no longer throws errors when it encounters old
372 serial files that do not conform to the current style

378 . Rewire some test-cases to swallow errors rather than expect them
379 . HTMLDefinition printer updated with some of the new attributes
380 . DefinitionCache keys reordered to reflect precedence: version number,
381 hash, then revision number
382 . %Core.DefinitionCache renamed to %Cache.DefinitionImpl
383 . Interlinking in configuration documentation added using
384 Injector_PurifierLinkify
385 . Directives now keep track of aliases to themselves
386 . Error collector now requires a severity to be passed, use PHP's internal
387 error constants for this
388 . HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
389 much easier selective embedding of configuration values
390 . Doctype objects now accept public and system DTD identifiers
391 . %HTML.Doctype is now constrained by specific values, to specify a custom
392 doctype use new %HTML.CustomDoctype
393 . ConfigForm truncates long directives to keep the form small, and does
394 not re-output namespaces
396 2.0.0, released 2007-06-20
397 # Completely refactored HTMLModuleManager, decentralizing safety
399 # Transform modules changed to Tidy modules, which offer more flexibility
400 and better modularization
401 # Configuration object now finalizes itself when a read operation is
402 performed on it, ensuring that its internal state stays consistent.
403 To revert this behavior, you can set the $autoFinalize member variable
404 off, but it's not recommended.
405 # New compact syntax for AttrDef objects that can be used to instantiate
406 new objects via make()
407 # Definitions (esp. HTMLDefinition) are now cached for a significant
408 performance boost. You can disable caching by setting %Core.DefinitionCache
409 to null. You CANNOT edit raw definitions without setting the corresponding
410 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
411 # Contents between <script> tags are now completely removed if <script>
413 # Prototype-declarations for Lexer removed in favor of configuration
414 determination of Lexer implementations.

428 - Deprecated and removed EnableRedundantUTF8Cleaning. It didn't even work!
429 - DOMLex will not emit errors when a custom error handler that does not
430 honor error_reporting is used
431 - StrictBlockquote child definition refrains from wrapping whitespace
433 - Bug resulting from tag transforms to non-allowed elements fixed
434 - ChildDef_Custom's regex generation has been improved, removing several
436 . Unit test for ElementDef created, ElementDef behavior modified to
438 . Added convenience functions for HTMLModule constructors
439 . AttrTypes now has accessor functions that should be used instead
440 of directly manipulating info
441 . TagTransform_Center deprecated in favor of generic TagTransform_Simple

456 + size and noshade in hr
459 + align in caption, table, img and hr
460 + type in ul, ol and li

464 ! %Core.RemoveInvalidImg is now operational, when set to false invalid
465 images will hang around with an empty src
466 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
468 ! CSS property white-space now allows nowrap (supported in all modern
469 browsers) but not others (which have spotty browser implementations)
470 ! XHTML 1.1 mode now sort-of works without any fatal errors, and
471 lang is now moved over to xml:lang.
472 ! Attribute transformation smoketest available at smoketests/attrTransform.php
473 ! Transformation of font's size attribute now handles super-large numbers
474 - Possibly fatal bug with __autoload() fixed in module manager
475 - Invert HTMLModuleManager->addModule() processing order to check

499 %Attr.IDBlacklistRegexp
500 - Error messages are emitted when you attempt to "allow" elements or
501 attributes that HTML Purifier does not support
502 - Fix segfault in unit test. The problem is not very reproduceable and
503 I don't know what causes it, but a six line patch fixed it.
505 1.5.0, released 2007-03-23
506 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
507 doesn't actually do anything yet, but keep your eyes peeled.
508 ! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
509 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.
