Code Releases Activity

Fix two bugs with caching of customized raw definitions.

Browse Source 
The first bug is that we will repeatedly write out the result
of a customized raw definition to the filesystem, even when a cache
entry already exists.

The second bug is that caching these definitions doesn't actually
work (the cache entry is written but never used.)  A new API
for retrieving raw definitions permits the user to take advantage
of caching.

would be retrieving a fully formed definition object, which is somewhat placed it in an if block: this is because
useless for customization purposes. <code>maybeGetRawHTMLDefinition</code>, as its name suggests, may
return a NULL, in which case we should skip doing any
initialization. This, in fact, will correspond to when our fully
customized object is already in the cache.

<h3>Broken backwards-compatibility</h3>
<p>
Those of you who have already been twiddling around with the raw
HTML definition object, you'll be noticing that you're getting an error
when you attempt to retrieve the raw definition object without specifying
a DefinitionID. It is vital to caching (see below) that you make a unique
name for your customized definition, so make up something right now and
things will operate again.

<h2 id="optimized">Notes for HTML Purifier 4.2.0 and earlier</h3>
<p>
Previously, this tutorial gave some incorrect template code for
editing raw definitions, and that template code will now produce the
error <q>Due to a documentation error in previous version of HTML
Purifier...</q> Here is how to mechanically transform old-style
code into new-style code.
</p>
<p>
First, identify all code that edits the raw definition object, and
put it together. Ensure none of this code must be run on every
request; if some sub-part needs to always be run, move it outside
this block. Here is an example below, with the raw definition
object code bolded.
</p>
<pre>$config = HTMLPurifier_Config::createDefault();
$config-&gt;set('HTML.DefinitionID', 'enduser-customize.html tutorial');
$config-&gt;set('HTML.DefinitionRev', 1);
$def = $config-&gt;getHTMLDefinition(true);
<strong>$def->addAttribute('a', 'target', 'Enum#_blank,_self,_target,_top');</strong>
$purifier = new HTMLPurifier($config);</pre>
<p>
Next, replace the raw definition retrieval with a
maybeGetRawHTMLDefinition method call inside an if conditional, and
place the editing code inside that if block.
</p>
<pre>$config = HTMLPurifier_Config::createDefault();
$config-&gt;set('HTML.DefinitionID', 'enduser-customize.html tutorial');
$config-&gt;set('HTML.DefinitionRev', 1);
<strong>if ($def = $config-&gt;maybeGetRawHTMLDefinition()) {
$def->addAttribute('a', 'target', 'Enum#_blank,_self,_target,_top');
}</strong>
$purifier = new HTMLPurifier($config);</pre>
<p>
And you're done! Alternatively, if you're OK with not ever caching
your code, the following will still work and not emit warnings.
</p>
<pre>$config = HTMLPurifier_Config::createDefault();
$def = $config-&gt;getHTMLDefinition(true);
$def->addAttribute('a', 'target', 'Enum#_blank,_self,_target,_top');
$purifier = new HTMLPurifier($config);</pre>
<p>
A slightly less efficient version of this was what was going on with
old versions of HTML Purifier.
</p>
<p>
<em>Technical notes:</em> ajh pointed out on <a
href="http://htmlpurifier.org/phorum/read.php?5,5164,5169#msg-5169">in a forum topic</a> that
HTML Purifier appeared to be repeatedly writing to the cache even
when a cache entry already existed. Investigation lead to the
discovery of the following infelicity: caching of customized
definitions didn't actually work! The problem was that even though
a cache file would be written out at the end of the process, there
was no way for HTML Purifier to say, <q>Actually, I've already got a
copy of your work, no need to reconfigure your
customizations</q>. This required the API to change: placing
all of the customizations to the raw definition object in a
conditional which could be skipped.
