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 - Fix stray backslashes in font-family
21 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
22 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
24 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
25 to __construct($min, $max). __construct(true) is equivalent to
27 . Added HTMLPurifier_AttrDef_Switch class
28 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
29 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
30 get this called with the configuration object. All modules now
31 use this rather than __construct(), although legacy code using constructors
32 will still work--the new format, however, lets modules access the
33 configuration object for HTML namespace dependant tweaks.
34 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
35 . ConfigSchema data-structure heavily optimized; on average it uses a third
36 the memory it did previously. The interface has changed accordingly,
37 consult changes to HTMLPurifier_Config for details.
38 . Variable parsing types now are magic integers instead of strings
39 . Added benchmark for ConfigSchema
42 3.1.0, released 2008-05-18
43 # Unnecessary references to objects (vestiges of PHP4) removed from method
44 signatures. The following methods do not need references when assigning from
45 them and will result in E_STRICT errors if you try:
46 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
47 + HTMLPurifier_ConfigSchema::instance()
48 + HTMLPurifier_DefinitionCacheFactory::instance()
49 + HTMLPurifier_DefinitionCacheFactory->create()
50 + HTMLPurifier_DoctypeRegistry->register()
51 + HTMLPurifier_DoctypeRegistry->get()
52 + HTMLPurifier_HTMLModule->addElement()
53 + HTMLPurifier_HTMLModule->addBlankElement()
54 + HTMLPurifier_LanguageFactory::instance()
55 # Printer_ConfigForm's get*() functions were static-ified
56 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
57 form of tag@attr, NOT tag.attr (which will throw an error and won't do
58 anything). This is for forwards compatibility with XML; you'd do best
59 to migrate an %HTML.AllowedAttributes directives to this syntax too.
60 ! Allow index to be false for config from form creation
61 ! Added HTMLPurifier::VERSION constant
62 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
63 and allows for version numbers like "3.1.0-dev".
64 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
65 ! HTML Purifier's URI handling is a lot more robust, with much stricter
66 validation checks and better percent encoding handling.
67 ! Bootstrap autoloader deals more robustly with classes that don't exist,
68 preventing class_exists($class, true) from barfing.
69 - InterchangeBuilder now alphabetizes its lists
70 - Validation error in configdoc output fixed
71 - Iconv and other encoding errors muted even with custom error handlers that
72 do not honor error_reporting
73 - Add protection against imagecrash attack with CSS height/width
74 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
75 - Fixed and revamped broken ConfigForm smoketest
76 - Bug with bool/null fields in Printer_ConfigForm fixed
77 - Bug with global forbidden attributes fixed
78 - Improved error messages for allowed and forbidden HTML elements and attributes
79 - Missing (or null) in configdoc documentation restored
80 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
81 of DOM), HTML Purifier punts to DirectLex
82 - Fatal error with unserialization of ScriptRequired
83 - Created directories are now chmod'ed properly
84 - Fixed bug with fallback languages in LanguageFactory
85 - Standalone testing setup properly with autoload
86 . Out-of-date documentation revised
87 . UTF-8 encoding check optimization as suggested by Diego
88 . HTMLPurifier_Error removed in favor of exceptions
89 . More copy() function removed; should use clone instead
90 . More extensive unit tests for HTMLDefinition
91 . assertPurification moved to central harness
92 . HTMLPurifier_Generator accepts $config and $context parameters during
93 instantiation, not runtime
94 . Double-quotes outside of attribute values are now unescaped
96 3.1.0rc1, released 2008-04-22
97 # Autoload support added. Internal require_once's removed in favor of an
98 explicit require list or autoloading. To use HTML Purifier,
99 you must now either use HTMLPurifier.auto.php
100 or HTMLPurifier.includes.php; setting the include path and including
101 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
102 as well to register our autoload handler (or modify your autoload function
103 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
104 HTMLPurifier.safe-includes.php for a less performance friendly but more
105 user-friendly library load.
106 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
107 information is stored in the ConfigSchema directory, and the
108 maintenance/generate-schema-cache.php generates the schema.ser file, which
109 is now instantiated. Support for userland schema changes coming soon!
110 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
111 alias; to get rid of these errors just modify your configuration to use
112 the new directive name.
113 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
114 enabled using %Filter.$filter_name or by setting your own filters using
116 # Directive-level safety properties superceded in favor of module-level
117 safety. Internal method HTMLModule->addElement() has changed, although
118 the externally visible HTMLDefinition->addElement has *not* changed.
119 ! Extra utility classes for testing and non-library operations can
120 be found in extras/. Specifically, these are FSTools and ConfigDoc.
121 You may find a use for these in your own project, but right now they
122 are highly experimental and volatile.
123 ! Integration with PHPT allows for automated smoketests
124 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
125 by Chris. You can enable them with %HTML.Proprietary if your client
127 ! Support for !important CSS cascade modifier. By default, this will be stripped
128 from CSS, but you can enable it using %CSS.AllowImportant
129 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
131 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
132 Developer error (not enduser error) can cause these to be triggered.
133 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
134 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
135 mucking around with HTMLPurifier_CSSDefinition
136 ! ConfigDoc output has been enhanced with version and deprecation info.
137 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
138 - Autoclose now operates iteratively, i.e. <span><span><div> now has
139 both span tags closed.
140 - Various HTMLPurifier_Config convenience functions now accept another parameter
141 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
143 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
144 - Fix bug in ExtractStyleBlocks with comments in style tags
145 - Fix bug in comment parsing for DirectLex
146 - Flush output now displayed when in command line mode for unit tester
147 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
148 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
149 on the same element without emitting errors.
150 - Fixed fatal error in PH5P lexer with invalid tag names
151 . Plugins now get their own changelogs according to project conventions.
152 . Convert tokens to use instanceof, reducing memory footprint and
153 improving comparison speed.
154 . Dry runs now supported in SimpleTest; testing facilities improved
155 . Bootstrap class added for handling autoloading functionality
156 . Implemented recursive glob at FSTools->globr
157 . ConfigSchema now has instance methods for all corresponding define*
159 . A couple of new historical maintenance scripts were added.
160 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
161 . tests/index.php can now be run from any directory.
162 . HTMLPurifier_Token subclasses split into seperate files
163 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
164 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
165 . New --php=php flag added, allows PHP executable to be specified (command
167 . htmlpurifier_add_test() preferred method to translate test files in to
168 classes, because it handles PHPT files too.
169 . Debugger class is deprecated and will be removed soon.
170 . Command line argument parsing for testing scripts revamped, now --opt value
172 . Smoketests now cleanup after magic quotes
173 . Generator now can output comments (however, comments are still stripped
174 from HTML Purifier output)
175 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
176 HTMLPurifier_VarParser->parse()
177 . Integers auto-cast into float type by VarParser.
178 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
179 during cache generation
180 . Reordered script calls in maintenance/flush.php
181 . Command line scripts now honor exit codes
182 . When --flush fails in unit testers, abort tests and print message
183 . Improved documentation in docs/dev-flush.html about the maintenance scripts
184 . copy() methods removed in favor of clone keyword
186 3.0.0, released 2008-01-06
187 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
188 until PHP 4 is completely deprecated, but no new features will be added
190 + Visibility declarations added
191 + Constructor methods renamed to __construct()
192 + PHP4 reference cruft removed (in progress)
193 ! CSS properties are now case-insensitive
194 ! DefinitionCacheFactory now can register new implementations
195 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
196 documents and cleaning their contents up. Requires the CSSTidy library
197 <http://csstidy.sourceforge.net/>. You can access the blocks with the
198 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
199 The output CSS can also be "scoped" for a specific element, use:
200 %Filter.ExtractStyleBlocksScope
201 ! Experimental support for some proprietary CSS attributes allowed:
202 opacity (and all of the browser-specific equivalents) and scrollbar colors.
203 Enable by setting %CSS.Proprietary to true.
204 - Colors missing # but in hex form will be corrected
205 - CSS Number algorithm improved
206 - Unit testing and multi-testing now on steroids: command lines,
207 XML output, and other goodies now added.
208 . Unit tests for Injector improved
210 + HTMLPurifier_AttrDef_CSS_AlphaValue
211 + HTMLPurifier_AttrDef_CSS_Filter
212 . Multitest now has a file docblock
214 2.1.3, released 2007-11-05
215 ! tests/multitest.php allows you to test multiple versions by running
216 tests/index.php through multiple interpreters using `phpv` shell
217 script (you must provide this script!)
218 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
220 - Injector algorithm further refined: off-by-one error regarding skip
221 counts for dormant injectors fixed
222 - Corrective blockquote definition now enabled for HTML 4.01 Strict
223 - Fatal error when <img> tag (or any other element with required attributes)
224 has 'id' attribute fixed, thanks NykO18 for reporting
225 - Fix warning emitted when a non-supported URI scheme is passed to the
226 MakeAbsolute URIFilter, thanks NykO18 (again)
227 - Further refine AutoParagraph injector. Behavior inside of elements
228 allowing paragraph tags clarified: only inline content delimeted by
229 double newlines (not block elements) are paragraphed.
230 - Buggy treatment of end tags of elements that have required attributes
231 fixed (does not manifest on default tag-set)
232 - Spurious internal content reorganization error suppressed
233 - HTMLDefinition->addElement now returns a reference to the created
234 element object, as implied by the documentation
235 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
236 - Fix a theoretical class of infinite loops from DirectLex reported
238 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
240 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
241 HTMLDefinition errors, this may indicate problems with error-collecting
243 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
244 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
245 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
246 to better communicate its purpose
247 . Error unit tests can now specify the expectation of no errors. Future
248 iterations of the harness will be extremely strict about what errors
250 . Extend Injector hooks to allow for more powerful injector routines
251 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
253 . Doxygen configuration file updated, with minor improvements
254 . Test runner now checks for similarly named files in conf/ directory too.
255 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
257 . Maintenance script for generating PH5P patch added, original PH5P source
258 file also added under version control
259 . Full unit test runner script title made more descriptive with PHP version
260 . Updated INSTALL file to state that 4.3.7 is the earliest version we
263 2.1.2, released 2007-09-03
264 ! Implemented Object module for trusted users
265 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
267 require_once 'HTMLPurifier/Lexer/PH5P.php';
268 $config->set('Core', 'LexerImpl', 'PH5P');
269 Note that this Lexer introduces some classes not in the HTMLPurifier
270 namespace. Also, this is PHP5 only.
271 ! CSS property border-spacing implemented
272 - Fix non-visible parsing error in DirectLex with empty tags that have
273 slashes inside attribute values.
274 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
275 accepted as valid CSS. Usually non-visible, because this styling is the
276 default for tables in most browsers. Thanks Brett Zamir for pointing
278 - Fix validation errors in configuration form
279 - Hammer out a bunch of edge-case bugs in the standalone distribution
280 - Inclusion reflection removed from URISchemeRegistry; you must manually
281 include any new schema files you wish to use
282 - Numerous typo fixes in documentation thanks to Brett Zamir
283 . Unit test refactoring for one logical test per test function
284 . Config and context parameters in ComplexHarness deprecated: instead, edit
285 the $config and $context member variables
286 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
287 really make a difference, but is good for completeness sake
288 . merge-library.php script refactored for greater code reusability and
291 2.1.1, released 2007-08-04
292 - Fix show-stopper bug in %URI.MakeAbsolute functionality
293 - Fix PHP4 syntax error in standalone version
294 . Add prefix directory to include path for standalone, this prevents
295 other installations from clobbering the standalone's URI schemes
296 . Single test methods can be invoked by prefixing with __only
298 2.1.0, released 2007-08-02
299 # flush-htmldefinition-cache.php superseded in favor of a generic
300 flush-definition-cache.php script, you can clear a specific cache
301 by passing its name as a parameter to the script
302 ! Phorum mod implemented for HTML Purifier
303 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
304 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
305 for PHP4 (DirectLex).
306 ! Standalone file now available, which greatly reduces the amount of
307 includes (although there are still a few files that reside in the
309 ! Relative URIs can now be transformed into their absolute equivalents
310 using %URI.Base and %URI.MakeAbsolute
311 ! Ruby implemented for XHTML 1.1
312 ! You can now define custom URI filtering behavior, see enduser-uri-filter.html

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

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

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

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

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

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