     HTML Purifier attempts to be as smart as possible when registering an

-    
+
     PHP VERSION IS LESS THAN 5.1.2, AND YOU'VE DEFINED __autoload
         Because spl_autoload_register() doesn't exist in early versions
         of PHP 5, HTML Purifier has no way of adding itself to the autoload
         stack. Modify your __autoload function to test
         HTMLPurifier_Bootstrap::autoload($class)
-        
+
         For example, suppose your autoload function looks like this:
-        
+
             function __autoload($class) {
                 require str_replace('_', '/', $class) . '.php';

-

             function __autoload($class) {

             }

+
         Note that there *is* some custom behavior in our autoloader; the
         original autoloader in our example would work for 99% of the time,
         but would fail when including language files.

+. Fix newline errors that caused spurious failures when CRLF HTML Purifier was
+  tested on Linux.
+. Removed trailing whitespace from all text files, see
+  remote-trailing-whitespace.php maintenance script.
+. Convert configuration to use property list backend.
+
+3.2.0, released 2008-10-31
+# Using %Core.CollectErrors forces line number/column tracking on, whereas
+  previously you could theoretically turn it off.
+# HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
+  use handleEnd() instead.
+! %Output.AttrSort for when you need your attributes in alphabetical order to
+  deal with a bug in FCKEditor. Requested by frank farmer.
+! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
+! Proper support for name attribute. It is now allowed and equivalent to the id
+  attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
+  is heavy (for all doctypes).
+! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
+  use on hand-written HTML.
+! Add error-cases for unsupported elements in MakeWellFormed. This enables
+  the strategy to be used, standalone, on untrusted input.
+! %Core.AggressivelyFixLt is on by default. This causes more sensible
+  processing of left angled brackets in smileys and other whatnot.
+! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
+  'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
+  the --only-phpt parameter, although for backwards-compatibility the flag
+  will still work.
+! AutoParagraph auto-formatter will now preserve double-newlines upon output.
+  Users who are not performing inbound filtering, this may seem a little
+  useless, but as a bonus, the test suite and handling of edge cases is also
+  improved.
+! Experimental implementation of forms for %HTML.Trusted
+! Track column numbers when maintain line numbers is on
+! Proprietary 'background' attribute on table-related elements converted into
+  corresponding CSS.  Thanks Fusemail for sponsoring this feature!
+! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
+  supertype.
+! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
+  time of operation varies slightly from notifyEnd() as *all* end tokens are
+  processed by the injector before they are subject to the well-formedness rules.
+! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
+  basename of image when not present.
+! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
+- Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
+  the other involving an undefined $is_folder error.
+- Throw error when %Core.Encoding is set to a spurious value. Previously,
+  this errored silently and returned false.
+- Redirected stderr to stdout for flush error output.
+- %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
+  available.
+- Do not re-munge URL if the output URL has the same host as the input URL.
+  Requested by Chris.
+- Fix error in documentation regarding %Filter.ExtractStyleBlocks
+- Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
+- Fix bug with inline elements in blockquotes conflicting with strict doctype
+- Detect if HTML support is disabled for DOM by checking for loadHTML() method.
+- Fix bug where dots and double-dots in absolute URLs without hostname were
+  not collapsed by URIFilter_MakeAbsolute.
+- Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
+  by reordering their addition.
+- Will now throw exception on many error conditions during lexer creation; also
+  throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
+  is being used.
+- Detect if domxml extension is loaded, and use DirectLEx accordingly.
+- Improve handling of big numbers with floating point arithmetic in UnitConverter.
+  Reported by David Morton.
+. Strategy_MakeWellFormed now operates in-place, saving memory and allowing
+  for more interesting filter-backtracking
+. New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
+  index to reprocess tokens.
+. StringHashParser now allows for multiline sections with "empty" content;
+  previously the section would remain undefined.
+. Added --quick option to multitest.php, which tests only the most recent
+  release for each series.
+. Added --distro option to multitest.php, which accepts either 'normal' or
+  'standalone'. This supercedes --exclude-normal and --exclude-standalone
+
+3.1.1, released 2008-06-19
+# %URI.Munge now, by default, does not munge resources (for example, <img src="">)
+  In order to enable this again, please set %URI.MungeResources to true.
+! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
+  and height/width HTML with %HTML.MaxImgLength.
+! %URI.MungeSecretKey for secure URI munging. Thanks Chris
+  for sponsoring this feature. Check out the corresponding documentation
+  for details. (Att Nightly testers: The API for this feature changed before
+  the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
+  %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
+! Implemented post URI filtering. Set member variable $post to true to set
+  a URIFilter as such.
+! Allow modules to define injectors via $info_injector. Injectors are
+  automatically disabled if injector's needed elements are not found.
+! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
+  Thanks Chris for sponsoring. If you've been using ad hoc code from the
+  forums, PLEASE use this instead.
+! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
+  embedded, tag name, attribute name, CSS property name). See %URI.Munge
+  for more details. Requested by Jochem Blok.
+- Disable percent height/width attributes for img.
+- AttrValidator operations are now atomic; updates to attributes are not
+  manifest in token until end of operations. This prevents naughty internal
+  code from directly modifying CurrentToken when they're not supposed to.
+  This semantics change was requested by frank farmer.
+- Percent encoding checks enabled for URI query and fragment
+- Fix stray backslashes in font-family; CSS Unicode character escapes are
+  now properly resolved (although *only* in font-family). Thanks Takeshi Terada
+  for reporting.
+- Improve parseCDATA algorithm to take into account newline normalization
+- Account for browser confusion between Yen character and backslash in
+  Shift_JIS encoding. This fix generalizes to any other encoding which is not
+  a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
+- Fix missing configuration parameter in Generator calls. Thanks vs for the
+  partial patch.
+- Improved adherence to Unicode by checking for non-character codepoints.
+  Thanks Geoffrey Sneddon for reporting. This may result in degraded
+  performance for extremely large inputs.
+- Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
+  for reporting.
+. Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
+  handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
+  this class.
+. API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
+  to __construct($min, $max). __construct(true) is equivalent to
+  __construct('0').
+. Added HTMLPurifier_AttrDef_Switch class
+. Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
+  up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
+  get this called with the configuration object.  All modules now
+  use this rather than __construct(), although legacy code using constructors
+  will still work--the new format, however, lets modules access the
+  configuration object for HTML namespace dependant tweaks.
+. AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
+. ConfigSchema data-structure heavily optimized; on average it uses a third
+  the memory it did previously. The interface has changed accordingly,
+  consult changes to HTMLPurifier_Config for details.
+. Variable parsing types now are magic integers instead of strings
+. Added benchmark for ConfigSchema
+. HTMLPurifier_Generator requires $config and $context parameters. If you
+  don't know what they should be, use HTMLPurifier_Config::createDefault()
+  and new HTMLPurifier_Context().
+. Printers now properly distinguish between output configuration, and
+  target configuration. This is not applicable to scripts using
+  the Printers for HTML Purifier related tasks.
+. HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
+  fatal errors will ensue.
+. URIFilter->prepare can return false in order to abort loading of the filter
+. Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
+  an external resource.
+. %URI.Munge functionality factored out into a post-filter class.
+. Added CurrentCSSProperty context variable during CSS validation

 <p>The founder of Taiji was Zhang Sanfeng (Chang San-feng), who was a monk of the Wu Dang (Wu Tang) Monastery and lived in the period from 1391 to 1459. His exercises stressed suppleness and elasticity as opposed to the hardness and force of other martial art styles. Several centuries old, Taiji was originally developed as a form of self-defense, emphasizing strength, balance, flexibility and speed. Tai Chi also differs from other martial arts in that it is based on the Taoist religion and aims to avoid aggressive forces. </p>

       HTML Purifier has a fairly complex system for configuration. Users
       interact with a <code>HTMLPurifier_Config</code> object to

+Considerations for ErrorCollection
+
+Presently, HTML Purifier takes a code-execution centric approach to handling
+errors. Errors are organized and grouped according to which segment of the
+code triggers them, not necessarily the portion of the input document that
+triggered the error. This means that errors are pseudo-sorted by category,
+rather than location in the document.
+
+One easy way to "fix" this problem would be to re-sort according to line number.
+However, the "category" style information we derive from naively following
+program execution is still useful. After all, each of the strategies which
+can report errors still process the document mostly linearly. Furthermore,
+not only do they process linearly, but the way they pass off operations to
+sub-systems mirrors that of the document. For example, AttrValidator will
+linearly proceed through elements, and on each element will use AttrDef to
+validate those contents. From there, the attribute might have more
+sub-components, which have execution passed off accordingly.
+
+In fact, each strategy handles a very specific class of "error."
+
+RemoveForeignElements   - element tokens
+MakeWellFormed          - element token ordering
+FixNesting              - element token ordering
+ValidateAttributes      - attributes of elements
+
+The crucial point is that while we care about the hierarchy governing these
+different errors, we *don't* care about any other information about what actually
+happens to the elements. This brings up another point: if HTML Purifier fixes
+something, this is not really a notice/warning/error; it's really a suggestion
+of a way to fix the aforementioned defects.
+
+In short, the refactoring to take this into account kinda sucks.
+
+Errors should not be recorded in order that they are reported. Instead, they
+should be bound to the line (and preferably element) in which they were found.
+This means we need some way to uniquely identify every element in the document,
+which doesn't presently exist. An easy way of adding this would be to track
+line columns. An important ramification of this is that we *must* use the
+DirectLex implementation.
+
+    1. Implement column numbers for DirectLex [DONE!]
+    2. Disable error collection when not using DirectLex [DONE!]
+
+Next, we need to re-orient all of the error declarations to place CurrentToken
+at utmost important. Since this is passed via Context, it's not always clear
+if that's available. ErrorCollector should complain HARD if it isn't available.
+There are some locations when we don't have a token available. These include:
+
+    * Lexing - this can actually have a row and column, but NOT correspond to
+      a token
+    * End of document errors - bump this to the end
+
+Actually, we *don't* have to complain if CurrentToken isn't available; we just
+set it as a document-wide error. And actually, nothing needs to be done here.
+
+Something interesting to consider is whether or not we care about the locations
+of attributes and CSS properties, i.e. the sub-objects that compose these things.
+In terms of consistency, at the very least attributes should have column/line
+numbers attached to them. However, this may be overkill, as attributes are
+uniquely identifiable. You could go even further, with CSS, but they are also
+uniquely identifiable.
+
+Bottom-line is, however, this information must be available, in form of the
+CurrentAttribute and CurrentCssProperty (theoretical) context variables, and
+it must be used to organize the errors that the sub-processes may throw.
+There is also a hierarchy of sorts that may make merging this into one context
+variable more sense, if it hadn't been for HTML's reasonably rigid structure.
+A CSS property will never contain an HTML attribute. So we won't ever get
+recursive relations, and having multiple depths won't ever make sense. Leave
+this be.
+
+We already have this information, and consequently, using start and end is
+*unnecessary*, so long as the context variables are set appropriately. We don't
+care if an error was thrown by an attribute transform or an attribute definition;
+to the end user these are the same (for a developer, they are different, but
+they're better off with a stack trace (which we should add support for) in such
+cases).
+
+    3. Remove start()/end() code. Don't get rid of recursion, though [DONE]
+    4. Setup ErrorCollector to use context information to setup hierarchies.
+       This may require a different internal format. Use objects if it gets
+       complex. [DONE]
+
+       ASIDE
+            More on this topic: since we are now binding errors to lines
+            and columns, a particular error can have three relationships to that
+            specific location:
+
+            1. The token at that location directly
+                RemoveForeignElements
+                AttrValidator (transforms)
+                MakeWellFormed
+            2. A "component" of that token (i.e. attribute)
+                AttrValidator (removals)
+            3. A modification to that node (i.e. contents from start to end
+               token) as a whole
+                FixNesting
+
+            This needs to be marked accordingly. In the presentation, it might
+            make sense keep (3) separate, have (2) a sublist of (1). (1) can
+            be a closing tag, in which case (3) makes no sense at all, OR it
+            should be related with its opening tag (this may not necessarily
+            be possible before MakeWellFormed is run).
+
+            So, the line and column counts as our identifier, so:
+
+            $errors[$line][$col] = ...
+
+            Then, we need to identify case 1, 2 or 3. They are identified as
+            such:
+
+            1. Need some sort of semaphore in RemoveForeignElements, etc.
+            2. If CurrentAttr/CurrentCssProperty is non-null
+            3. Default (FixNesting, MakeWellFormed)
+
+            One consideration about (1) is that it usually is actually a
+            (3) modification, but we have no way of knowing about that because
+            of various optimizations. However, they can probably be treated
+            the same. The other difficulty is that (3) is never a line and
+            column; rather, it is a range (i.e. a duple) and telling the user
+            the very start of the range may confuse them. For example,
+
+            <b>Foo<div>bar</div></b>
+            ^     ^
+
+            The node being operated on is <b>, so the error would be assigned
+            to the first caret, with a "node reorganized" error. Then, the
+            ChildDef would have submitted its own suggestions and errors with
+            regard to what's going in the internals.  So I suppose this is
+            ok. :-)
+
+            Now, the structure of the earlier mentioned ... would be something
+            like this:
+
+            object {
+                type = (token|attr|property),
+                value, // appropriate for type
+                errors => array(),
+                sub-errors = [recursive],
+            }
+
+            This helps us keep things agnostic. It is also sufficiently complex
+            enough to warrant an object.
+
+So, more wanking about the object format is in order. The way HTML Purifier is
+currently setup, the only possible hierarchy is:
+
+    token -> attr -> css property
+
+These relations do not exist all of the time; a comment or end token would not
+ever have any attributes, and non-style attributes would never have CSS properties
+associated with them.
+
+I believe that it is worth supporting multiple paths. At some point, we might
+have a hierarchy like:
+
+    * -> syntax
+      -> token -> attr -> css property
+                       -> url
+               -> css stylesheet <style>
+
+et cetera. Now, one of the practical implications of this is that every "node"
+on our tree is well-defined, so in theory it should be possible to either 1.
+create a separate class for each error struct, or 2. embed this information
+directly into HTML Purifier's token stream.  Embedding the information in the
+token stream is not a terribly good idea, since tokens can be removed, etc.
+So that leaves us with 1... and if we use a generic interface we can cut down
+on a lot of code we might need. So let's leave it like this.
+
+~~~~
+
+Then we setup suggestions.
+
+    5. Setup a separate error class which tells the user any modifications
+       HTML Purifier made.
+
+Some information about this:
+
+Our current paradigm is to tell the user what HTML Purifier did to the HTML.
+This is the most natural mode of operation, since that's what HTML Purifier
+is all about; it was not meant to be a validator.
+
+However, most other people have experience dealing with a validator. In cases
+where HTML Purifier unambiguously does the right thing, simply giving the user
+the correct version isn't a bad idea, but problems arise when:
+
+- The user has such bad HTML we do something odd, when we should have just
+  flagged the HTML as an error. Such examples are when we do things like
+  remove text from directly inside a <table> tag. It was probably meant to
+  be in a <td> tag or be outside the table, but we're not smart enough to
+  realize this so we just remove it. In such a case, we should tell the user
+  that there was foreign data in the table, but then we shouldn't "demand"
+  the user remove the data; it's more of a "here's a possible way of
+  rectifying the problem"
+
+- Giving line context for input is hard enough, but feasible; giving output
+  line context will be extremely difficult due to shifting lines; we'd probably
+  have to track what the tokens are and then find the appropriate out context
+  and it's not guaranteed to work etc etc etc.
+
