1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 3.1.0, unknown release date
13 # Unnecessary references to objects (vestiges of PHP4) removed from method
14 signatures. The following methods do not need references when assigning from
15 them and will result in E_STRICT errors if you try:
16 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
17 + HTMLPurifier_ConfigSchema::instance()
18 + HTMLPurifier_DefinitionCacheFactory::instance()
19 + HTMLPurifier_DefinitionCacheFactory->create()
20 + HTMLPurifier_DoctypeRegistry->register()
21 + HTMLPurifier_DoctypeRegistry->get()
22 + HTMLPurifier_HTMLModule->addElement()
23 + HTMLPurifier_HTMLModule->addBlankElement()
24 + HTMLPurifier_LanguageFactory::instance()
25 # Printer_ConfigForm's get*() functions were static-ified
26 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
27 form of tag@attr, NOT tag.attr (which will throw an error and won't do
28 anything). This is for forwards compatibility with XML; you'd do best
29 to migrate an %HTML.AllowedAttributes directives to this syntax too.
30 ! Allow index to be false for config from form creation
31 ! Added HTMLPurifier::VERSION constant
32 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
33 and allows for version numbers like "3.1.0-dev".
34 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
35 - InterchangeBuilder now alphabetizes its lists
36 - Validation error in configdoc output fixed
37 - Iconv and other encoding errors muted even with custom error handlers that
38 do not honor error_reporting
39 - Add protection against imagecrash attack with CSS height/width
40 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
41 - Fixed and revamped broken ConfigForm smoketest
42 - Bug with bool/null fields in Printer_ConfigForm fixed
43 - Bug with global forbidden attributes fixed
44 - Improved error messages for allowed and forbidden HTML elements and attributes
45 - Missing (or null) in configdoc documentation restored
46 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
47 of DOM), HTML Purifier punts to DirectLex
48 - Fatal error with unserialization of ScriptRequired
49 - Created directories are now chmod'ed properly
50 . Out-of-date documentation revised
51 . UTF-8 encoding check optimization as suggested by Diego
52 . HTMLPurifier_Error removed in favor of exceptions
53 . More copy() function removed; should use clone instead
54 . More extensive unit tests for HTMLDefinition
55 . assertPurification moved to central harness
56 . HTMLPurifier_Generator accepts $config and $context parameters during
57 instantiation, not runtime
58 . Double-quotes outside of attribute values are now unescaped
60 3.1.0rc1, released 2008-04-22
61 # Autoload support added. Internal require_once's removed in favor of an
62 explicit require list or autoloading. To use HTML Purifier,
63 you must now either use HTMLPurifier.auto.php
64 or HTMLPurifier.includes.php; setting the include path and including
65 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
66 as well to register our autoload handler (or modify your autoload function
67 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
68 HTMLPurifier.safe-includes.php for a less performance friendly but more
69 user-friendly library load.
70 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
71 information is stored in the ConfigSchema directory, and the
72 maintenance/generate-schema-cache.php generates the schema.ser file, which
73 is now instantiated. Support for userland schema changes coming soon!
74 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
75 alias; to get rid of these errors just modify your configuration to use
76 the new directive name.
77 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
78 enabled using %Filter.$filter_name or by setting your own filters using
80 # Directive-level safety properties superceded in favor of module-level
81 safety. Internal method HTMLModule->addElement() has changed, although
82 the externally visible HTMLDefinition->addElement has *not* changed.
83 ! Extra utility classes for testing and non-library operations can
84 be found in extras/. Specifically, these are FSTools and ConfigDoc.
85 You may find a use for these in your own project, but right now they
86 are highly experimental and volatile.
87 ! Integration with PHPT allows for automated smoketests
88 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
89 by Chris. You can enable them with %HTML.Proprietary if your client
91 ! Support for !important CSS cascade modifier. By default, this will be stripped
92 from CSS, but you can enable it using %CSS.AllowImportant
93 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
95 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
96 Developer error (not enduser error) can cause these to be triggered.
97 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
98 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
99 mucking around with HTMLPurifier_CSSDefinition
100 ! ConfigDoc output has been enhanced with version and deprecation info.
101 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
102 - Autoclose now operates iteratively, i.e. <span><span><div> now has
103 both span tags closed.
104 - Various HTMLPurifier_Config convenience functions now accept another parameter
105 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
107 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
108 - Fix bug in ExtractStyleBlocks with comments in style tags
109 - Fix bug in comment parsing for DirectLex
110 - Flush output now displayed when in command line mode for unit tester
111 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
112 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
113 on the same element without emitting errors.
114 - Fixed fatal error in PH5P lexer with invalid tag names
115 . Plugins now get their own changelogs according to project conventions.
116 . Convert tokens to use instanceof, reducing memory footprint and
117 improving comparison speed.
118 . Dry runs now supported in SimpleTest; testing facilities improved
119 . Bootstrap class added for handling autoloading functionality
120 . Implemented recursive glob at FSTools->globr
121 . ConfigSchema now has instance methods for all corresponding define*
123 . A couple of new historical maintenance scripts were added.
124 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
125 . tests/index.php can now be run from any directory.
126 . HTMLPurifier_Token subclasses split into seperate files
127 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
128 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
129 . New --php=php flag added, allows PHP executable to be specified (command
131 . htmlpurifier_add_test() preferred method to translate test files in to
132 classes, because it handles PHPT files too.
133 . Debugger class is deprecated and will be removed soon.
134 . Command line argument parsing for testing scripts revamped, now --opt value
136 . Smoketests now cleanup after magic quotes
137 . Generator now can output comments (however, comments are still stripped
138 from HTML Purifier output)
139 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
140 HTMLPurifier_VarParser->parse()
141 . Integers auto-cast into float type by VarParser.
142 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
143 during cache generation
144 . Reordered script calls in maintenance/flush.php
145 . Command line scripts now honor exit codes
146 . When --flush fails in unit testers, abort tests and print message
147 . Improved documentation in docs/dev-flush.html about the maintenance scripts
148 . copy() methods removed in favor of clone keyword
150 3.0.0, released 2008-01-06
151 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
152 until PHP 4 is completely deprecated, but no new features will be added
154 + Visibility declarations added
155 + Constructor methods renamed to __construct()
156 + PHP4 reference cruft removed (in progress)
157 ! CSS properties are now case-insensitive
158 ! DefinitionCacheFactory now can register new implementations
159 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
160 documents and cleaning their contents up. Requires the CSSTidy library
161 <http://csstidy.sourceforge.net/>. You can access the blocks with the
162 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
163 The output CSS can also be "scoped" for a specific element, use:
164 %Filter.ExtractStyleBlocksScope
165 ! Experimental support for some proprietary CSS attributes allowed:
166 opacity (and all of the browser-specific equivalents) and scrollbar colors.
167 Enable by setting %CSS.Proprietary to true.
168 - Colors missing # but in hex form will be corrected
169 - CSS Number algorithm improved
170 - Unit testing and multi-testing now on steroids: command lines,
171 XML output, and other goodies now added.
172 . Unit tests for Injector improved
174 + HTMLPurifier_AttrDef_CSS_AlphaValue
175 + HTMLPurifier_AttrDef_CSS_Filter
176 . Multitest now has a file docblock
178 2.1.3, released 2007-11-05
179 ! tests/multitest.php allows you to test multiple versions by running
180 tests/index.php through multiple interpreters using `phpv` shell
181 script (you must provide this script!)
182 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
184 - Injector algorithm further refined: off-by-one error regarding skip
185 counts for dormant injectors fixed
186 - Corrective blockquote definition now enabled for HTML 4.01 Strict
187 - Fatal error when <img> tag (or any other element with required attributes)
188 has 'id' attribute fixed, thanks NykO18 for reporting
189 - Fix warning emitted when a non-supported URI scheme is passed to the
190 MakeAbsolute URIFilter, thanks NykO18 (again)
191 - Further refine AutoParagraph injector. Behavior inside of elements
192 allowing paragraph tags clarified: only inline content delimeted by
193 double newlines (not block elements) are paragraphed.
194 - Buggy treatment of end tags of elements that have required attributes
195 fixed (does not manifest on default tag-set)
196 - Spurious internal content reorganization error suppressed
197 - HTMLDefinition->addElement now returns a reference to the created
198 element object, as implied by the documentation
199 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
200 - Fix a theoretical class of infinite loops from DirectLex reported
202 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
204 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
205 HTMLDefinition errors, this may indicate problems with error-collecting
207 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
208 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
209 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
210 to better communicate its purpose
211 . Error unit tests can now specify the expectation of no errors. Future
212 iterations of the harness will be extremely strict about what errors
214 . Extend Injector hooks to allow for more powerful injector routines
215 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
217 . Doxygen configuration file updated, with minor improvements
218 . Test runner now checks for similarly named files in conf/ directory too.
219 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
221 . Maintenance script for generating PH5P patch added, original PH5P source
222 file also added under version control
223 . Full unit test runner script title made more descriptive with PHP version
224 . Updated INSTALL file to state that 4.3.7 is the earliest version we
227 2.1.2, released 2007-09-03
228 ! Implemented Object module for trusted users
229 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
231 require_once 'HTMLPurifier/Lexer/PH5P.php';
232 $config->set('Core', 'LexerImpl', 'PH5P');
233 Note that this Lexer introduces some classes not in the HTMLPurifier
234 namespace. Also, this is PHP5 only.
235 ! CSS property border-spacing implemented
236 - Fix non-visible parsing error in DirectLex with empty tags that have
237 slashes inside attribute values.
238 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
239 accepted as valid CSS. Usually non-visible, because this styling is the
240 default for tables in most browsers. Thanks Brett Zamir for pointing
242 - Fix validation errors in configuration form
243 - Hammer out a bunch of edge-case bugs in the standalone distribution
244 - Inclusion reflection removed from URISchemeRegistry; you must manually
245 include any new schema files you wish to use
246 - Numerous typo fixes in documentation thanks to Brett Zamir
247 . Unit test refactoring for one logical test per test function
248 . Config and context parameters in ComplexHarness deprecated: instead, edit
249 the $config and $context member variables
250 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
251 really make a difference, but is good for completeness sake
252 . merge-library.php script refactored for greater code reusability and
255 2.1.1, released 2007-08-04
256 - Fix show-stopper bug in %URI.MakeAbsolute functionality
257 - Fix PHP4 syntax error in standalone version
258 . Add prefix directory to include path for standalone, this prevents
259 other installations from clobbering the standalone's URI schemes
260 . Single test methods can be invoked by prefixing with __only
262 2.1.0, released 2007-08-02
263 # flush-htmldefinition-cache.php superseded in favor of a generic
264 flush-definition-cache.php script, you can clear a specific cache
265 by passing its name as a parameter to the script
266 ! Phorum mod implemented for HTML Purifier
267 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
268 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
269 for PHP4 (DirectLex).
270 ! Standalone file now available, which greatly reduces the amount of
271 includes (although there are still a few files that reside in the
273 ! Relative URIs can now be transformed into their absolute equivalents
274 using %URI.Base and %URI.MakeAbsolute
275 ! Ruby implemented for XHTML 1.1

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

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

394 - DOMLex will not emit errors when a custom error handler that does not
395 honor error_reporting is used
396 - StrictBlockquote child definition refrains from wrapping whitespace
398 - Bug resulting from tag transforms to non-allowed elements fixed
399 - ChildDef_Custom's regex generation has been improved, removing several
401 . Unit test for ElementDef created, ElementDef behavior modified to
403 . Added convenience functions for HTMLModule constructors
404 . AttrTypes now has accessor functions that should be used instead
405 of directly manipulating info
406 . TagTransform_Center deprecated in favor of generic TagTransform_Simple

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

464 %Attr.IDBlacklistRegexp
465 - Error messages are emitted when you attempt to "allow" elements or
466 attributes that HTML Purifier does not support
467 - Fix segfault in unit test. The problem is not very reproduceable and
468 I don't know what causes it, but a six line patch fixed it.
470 1.5.0, released 2007-03-23
471 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
472 doesn't actually do anything yet, but keep your eyes peeled.
473 ! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
474 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.
