1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 3.2.0, unknown release date
14 3.1.0, released 2008-05-18
15 # Unnecessary references to objects (vestiges of PHP4) removed from method
16 signatures. The following methods do not need references when assigning from
17 them and will result in E_STRICT errors if you try:
18 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
19 + HTMLPurifier_ConfigSchema::instance()
20 + HTMLPurifier_DefinitionCacheFactory::instance()
21 + HTMLPurifier_DefinitionCacheFactory->create()
22 + HTMLPurifier_DoctypeRegistry->register()
23 + HTMLPurifier_DoctypeRegistry->get()
24 + HTMLPurifier_HTMLModule->addElement()
25 + HTMLPurifier_HTMLModule->addBlankElement()
26 + HTMLPurifier_LanguageFactory::instance()
27 # Printer_ConfigForm's get*() functions were static-ified
28 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
29 form of tag@attr, NOT tag.attr (which will throw an error and won't do
30 anything). This is for forwards compatibility with XML; you'd do best
31 to migrate an %HTML.AllowedAttributes directives to this syntax too.
32 ! Allow index to be false for config from form creation
33 ! Added HTMLPurifier::VERSION constant
34 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
35 and allows for version numbers like "3.1.0-dev".
36 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
37 ! HTML Purifier's URI handling is a lot more robust, with much stricter
38 validation checks and better percent encoding handling.
39 ! Bootstrap autoloader deals more robustly with classes that don't exist,
40 preventing class_exists($class, true) from barfing.
41 - InterchangeBuilder now alphabetizes its lists
42 - Validation error in configdoc output fixed
43 - Iconv and other encoding errors muted even with custom error handlers that
44 do not honor error_reporting
45 - Add protection against imagecrash attack with CSS height/width
46 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
47 - Fixed and revamped broken ConfigForm smoketest
48 - Bug with bool/null fields in Printer_ConfigForm fixed
49 - Bug with global forbidden attributes fixed
50 - Improved error messages for allowed and forbidden HTML elements and attributes
51 - Missing (or null) in configdoc documentation restored
52 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
53 of DOM), HTML Purifier punts to DirectLex
54 - Fatal error with unserialization of ScriptRequired
55 - Created directories are now chmod'ed properly
56 - Fixed bug with fallback languages in LanguageFactory
57 - Standalone testing setup properly with autoload
58 . Out-of-date documentation revised
59 . UTF-8 encoding check optimization as suggested by Diego
60 . HTMLPurifier_Error removed in favor of exceptions
61 . More copy() function removed; should use clone instead
62 . More extensive unit tests for HTMLDefinition
63 . assertPurification moved to central harness
64 . HTMLPurifier_Generator accepts $config and $context parameters during
65 instantiation, not runtime
66 . Double-quotes outside of attribute values are now unescaped
68 3.1.0rc1, released 2008-04-22
69 # Autoload support added. Internal require_once's removed in favor of an
70 explicit require list or autoloading. To use HTML Purifier,
71 you must now either use HTMLPurifier.auto.php
72 or HTMLPurifier.includes.php; setting the include path and including
73 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
74 as well to register our autoload handler (or modify your autoload function
75 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
76 HTMLPurifier.safe-includes.php for a less performance friendly but more
77 user-friendly library load.
78 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
79 information is stored in the ConfigSchema directory, and the
80 maintenance/generate-schema-cache.php generates the schema.ser file, which
81 is now instantiated. Support for userland schema changes coming soon!
82 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
83 alias; to get rid of these errors just modify your configuration to use
84 the new directive name.
85 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
86 enabled using %Filter.$filter_name or by setting your own filters using
88 # Directive-level safety properties superceded in favor of module-level
89 safety. Internal method HTMLModule->addElement() has changed, although
90 the externally visible HTMLDefinition->addElement has *not* changed.
91 ! Extra utility classes for testing and non-library operations can
92 be found in extras/. Specifically, these are FSTools and ConfigDoc.
93 You may find a use for these in your own project, but right now they
94 are highly experimental and volatile.
95 ! Integration with PHPT allows for automated smoketests
96 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
97 by Chris. You can enable them with %HTML.Proprietary if your client
99 ! Support for !important CSS cascade modifier. By default, this will be stripped
100 from CSS, but you can enable it using %CSS.AllowImportant
101 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
103 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
104 Developer error (not enduser error) can cause these to be triggered.
105 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
106 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
107 mucking around with HTMLPurifier_CSSDefinition
108 ! ConfigDoc output has been enhanced with version and deprecation info.
109 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
110 - Autoclose now operates iteratively, i.e. <span><span><div> now has
111 both span tags closed.
112 - Various HTMLPurifier_Config convenience functions now accept another parameter
113 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
115 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
116 - Fix bug in ExtractStyleBlocks with comments in style tags
117 - Fix bug in comment parsing for DirectLex
118 - Flush output now displayed when in command line mode for unit tester
119 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
120 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
121 on the same element without emitting errors.
122 - Fixed fatal error in PH5P lexer with invalid tag names
123 . Plugins now get their own changelogs according to project conventions.
124 . Convert tokens to use instanceof, reducing memory footprint and
125 improving comparison speed.
126 . Dry runs now supported in SimpleTest; testing facilities improved
127 . Bootstrap class added for handling autoloading functionality
128 . Implemented recursive glob at FSTools->globr
129 . ConfigSchema now has instance methods for all corresponding define*
131 . A couple of new historical maintenance scripts were added.
132 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
133 . tests/index.php can now be run from any directory.
134 . HTMLPurifier_Token subclasses split into seperate files
135 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
136 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
137 . New --php=php flag added, allows PHP executable to be specified (command
139 . htmlpurifier_add_test() preferred method to translate test files in to
140 classes, because it handles PHPT files too.
141 . Debugger class is deprecated and will be removed soon.
142 . Command line argument parsing for testing scripts revamped, now --opt value
144 . Smoketests now cleanup after magic quotes
145 . Generator now can output comments (however, comments are still stripped
146 from HTML Purifier output)
147 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
148 HTMLPurifier_VarParser->parse()
149 . Integers auto-cast into float type by VarParser.
150 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
151 during cache generation
152 . Reordered script calls in maintenance/flush.php
153 . Command line scripts now honor exit codes
154 . When --flush fails in unit testers, abort tests and print message
155 . Improved documentation in docs/dev-flush.html about the maintenance scripts
156 . copy() methods removed in favor of clone keyword
158 3.0.0, released 2008-01-06
159 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
160 until PHP 4 is completely deprecated, but no new features will be added
162 + Visibility declarations added
163 + Constructor methods renamed to __construct()
164 + PHP4 reference cruft removed (in progress)
165 ! CSS properties are now case-insensitive

167 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
168 documents and cleaning their contents up. Requires the CSSTidy library
169 <http://csstidy.sourceforge.net/>. You can access the blocks with the
170 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
171 The output CSS can also be "scoped" for a specific element, use:
172 %Filter.ExtractStyleBlocksScope
173 ! Experimental support for some proprietary CSS attributes allowed:
174 opacity (and all of the browser-specific equivalents) and scrollbar colors.
175 Enable by setting %CSS.Proprietary to true.
176 - Colors missing # but in hex form will be corrected
177 - CSS Number algorithm improved
178 - Unit testing and multi-testing now on steroids: command lines,
179 XML output, and other goodies now added.
180 . Unit tests for Injector improved
182 + HTMLPurifier_AttrDef_CSS_AlphaValue
183 + HTMLPurifier_AttrDef_CSS_Filter
184 . Multitest now has a file docblock
186 2.1.3, released 2007-11-05
187 ! tests/multitest.php allows you to test multiple versions by running
188 tests/index.php through multiple interpreters using `phpv` shell
189 script (you must provide this script!)
190 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
192 - Injector algorithm further refined: off-by-one error regarding skip
193 counts for dormant injectors fixed
194 - Corrective blockquote definition now enabled for HTML 4.01 Strict
195 - Fatal error when <img> tag (or any other element with required attributes)
196 has 'id' attribute fixed, thanks NykO18 for reporting
197 - Fix warning emitted when a non-supported URI scheme is passed to the
198 MakeAbsolute URIFilter, thanks NykO18 (again)
199 - Further refine AutoParagraph injector. Behavior inside of elements
200 allowing paragraph tags clarified: only inline content delimeted by
201 double newlines (not block elements) are paragraphed.
202 - Buggy treatment of end tags of elements that have required attributes
203 fixed (does not manifest on default tag-set)
204 - Spurious internal content reorganization error suppressed
205 - HTMLDefinition->addElement now returns a reference to the created
206 element object, as implied by the documentation
207 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
208 - Fix a theoretical class of infinite loops from DirectLex reported
210 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
212 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
213 HTMLDefinition errors, this may indicate problems with error-collecting
215 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
216 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
217 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
218 to better communicate its purpose
219 . Error unit tests can now specify the expectation of no errors. Future
220 iterations of the harness will be extremely strict about what errors
222 . Extend Injector hooks to allow for more powerful injector routines
223 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
225 . Doxygen configuration file updated, with minor improvements
226 . Test runner now checks for similarly named files in conf/ directory too.
227 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
229 . Maintenance script for generating PH5P patch added, original PH5P source
230 file also added under version control
231 . Full unit test runner script title made more descriptive with PHP version
232 . Updated INSTALL file to state that 4.3.7 is the earliest version we
235 2.1.2, released 2007-09-03
236 ! Implemented Object module for trusted users
237 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
239 require_once 'HTMLPurifier/Lexer/PH5P.php';
240 $config->set('Core', 'LexerImpl', 'PH5P');
241 Note that this Lexer introduces some classes not in the HTMLPurifier
242 namespace. Also, this is PHP5 only.
243 ! CSS property border-spacing implemented
244 - Fix non-visible parsing error in DirectLex with empty tags that have
245 slashes inside attribute values.
246 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
247 accepted as valid CSS. Usually non-visible, because this styling is the
248 default for tables in most browsers. Thanks Brett Zamir for pointing
250 - Fix validation errors in configuration form
251 - Hammer out a bunch of edge-case bugs in the standalone distribution
252 - Inclusion reflection removed from URISchemeRegistry; you must manually
253 include any new schema files you wish to use
254 - Numerous typo fixes in documentation thanks to Brett Zamir
255 . Unit test refactoring for one logical test per test function
256 . Config and context parameters in ComplexHarness deprecated: instead, edit
257 the $config and $context member variables
258 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
259 really make a difference, but is good for completeness sake
260 . merge-library.php script refactored for greater code reusability and
263 2.1.1, released 2007-08-04
264 - Fix show-stopper bug in %URI.MakeAbsolute functionality
265 - Fix PHP4 syntax error in standalone version
266 . Add prefix directory to include path for standalone, this prevents
267 other installations from clobbering the standalone's URI schemes
268 . Single test methods can be invoked by prefixing with __only
270 2.1.0, released 2007-08-02
271 # flush-htmldefinition-cache.php superseded in favor of a generic
272 flush-definition-cache.php script, you can clear a specific cache
273 by passing its name as a parameter to the script
274 ! Phorum mod implemented for HTML Purifier
275 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
276 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
277 for PHP4 (DirectLex).
278 ! Standalone file now available, which greatly reduces the amount of
279 includes (although there are still a few files that reside in the
281 ! Relative URIs can now be transformed into their absolute equivalents
282 using %URI.Base and %URI.MakeAbsolute
283 ! Ruby implemented for XHTML 1.1
284 ! You can now define custom URI filtering behavior, see enduser-uri-filter.html

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

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

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

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

472 %Attr.IDBlacklistRegexp
473 - Error messages are emitted when you attempt to "allow" elements or
474 attributes that HTML Purifier does not support
475 - Fix segfault in unit test. The problem is not very reproduceable and
476 I don't know what causes it, but a six line patch fixed it.
478 1.5.0, released 2007-03-23
479 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
480 doesn't actually do anything yet, but keep your eyes peeled.
481 ! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
482 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.

502 . AttrDef partitioned into HTML, CSS and URI segments
503 . Modify Youtube filter regexp to be multiline
504 . Require both PHP5 and DOM extension in order to use DOMLex, fixes
