If you've been poking around the various folders in HTML Purifier,
|
|
|
|
|
you may have noticed the <code>maintenance</code> directory. Almost
|
|
|
|
|
all of these scripts are devoted to flushing out the various caches
|
|
|
|
|
HTML Purifier uses. Normal users don't have to worry about this:
|
|
|
|
|
regular library usage is transparent. However, when doing development
|
|
|
|
|
work on HTML Purifier, you may find you have to flush one of the
|
|
|
|
|
caches.
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
As a general rule of thumb, run <code>flush.php</code> whenever you make
|
|
|
|
|
any <em>major</em> changes, or when tests start mysteriously failing.
|
|
|
|
|
In more detail, run this script if:
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
<li>
|
|
|
|
|
You added new source files to HTML Purifier's main library.
|
|
|
|
|
(see <code>generate-includes.php</code>)
|
|
|
|
|
</li>
|
|
|
|
|
<li>
|
|
|
|
|
You modified the configuration schema (see
|
|
|
|
|
<code>generate-schema-cache.php</code>). This usually means
|
|
|
|
|
adding or modifying files in <code>HTMLPurifier/ConfigSchema/schema/</code>,
|
|
|
|
|
although in rare cases modifying <code>HTMLPurifier/ConfigSchema.php</code>
|
|
|
|
|
will also require this.
|
|
|
|
|
</li>
|
|
|
|
|
<li>
|
|
|
|
|
You modified a Definition, or its subsystems. The most usual candidate
|
|
|
|
|
is <code>HTMLPurifier/HTMLDefinition.php</code>, which also encompasses
|
|
|
|
|
the files in <code>HTMLPurifier/HTMLModule/</code> as well as if you've
|
|
|
|
|
<a href="enduser-customize.html">customizing definitions</a> without
|
|
|
|
|
the cache disabled. (see <code>flush-generation-cache.php</code>)
|
|
|
|
|
</li>
|
|
|
|
|
<li>
|
|
|
|
|
You modified source files, and have been using the standalone
|
|
|
|
|
version from the full installation. (see <code>generate-standalone.php</code>)
|
|
|
|
|
</li>
|
|
|
|
|
</ul>
|
|
|

do.
