Configuration Backwards-Compatibility Breaks
|
||
|
|
|
||
|
|
In version 3.3.0, the configuration subsystem (composed of the outwards
|
||
|
|
facing Config class, as well as the ConfigSchema and ConfigSchema_Interchange
|
||
|
|
subsystems), was significantly revamped to make use of property lists.
|
||
|
|
While most of the changes are internal, some internal APIs were changed for the
|
||
|
|
sake of clarity. HTMLPurifier_Config was kept completely backwards compatible,
|
||
|
|
although some of the functions were retrofitted with an unambiguous alternate
|
||
|
|
syntax. Both of these changes are discussed in this document.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
1. Outwards Facing Changes
|
||
|
|
--------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
The HTMLPurifier_Config class now takes an alternate syntax. The general rule
|
||
|
|
is:
|
||
|
|
|
||
|
|
If you passed $namespace, $directive, pass "$namespace.$directive"
|
||
|
|
instead.
|
||
|
|
|
||
|
|
An example:
|
||
|
|
|
||
|
|
$config->set('HTML', 'Allowed', 'p');
|
||
|
|
|
||
|
|
becomes:
|
||
|
|
|
||
|
|
$config->set('HTML.Allowed', 'p');
|
||
|
|
|
||
|
|
New configuration options may have more than one namespace, they might
|
||
|
|
look something like %Filter.YouTube.Blacklist. While you could technically
|
||
|
|
set it with ('HTML', 'YouTube.Blacklist'), the logical extension
|
||
|
|
('HTML', 'YouTube', 'Blacklist') does not work.
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
2. Internal API Changes
|
||
|
|
--------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
Some overarching notes: we've completely eliminated the notion of namespace;
|
||
|
|
it's now an informal construct for organizing related configuration directives.
|
||
|
|
|
||
|
|
Also, the validation routines for keys (formerly "$namespace.$directive")
|
||
|
|
have been completely relaxed. I don't think it really should be necessary.
|
||
|
|
|
||
|
|
2.1 HTMLPurifier_ConfigSchema
|
||
|
|
|
||
|
|
First off, if you're interfacing with this class, you really shouldn't.
|
||
|
|
HTMLPurifier_ConfigSchema_Builder_ConfigSchema is really the only class that
|
||
|
|
should ever be creating HTMLPurifier_ConfigSchema, and HTMLPurifier_Config the
|
||
|
|
only class that should be reading it.
|
||
|
|
|
||
|
|
All namespace related methods were removed; they are completely unnecessary
|
||
|
|
now. Any $namespace, $name arguments must be replaced with $key (where
|
||
|
|
$key == "$namespace.$name"), including for addAlias().
|
||
|
|
|
||
|
|
The $info and $defaults member variables are no longer indexed as
|
||
|
|
[$namespace][$name]; they are now indexed as ["$namespace.$name"].
|
||
|
|
|
||
|
|
All deprecated methods were finally removed, after having yelled at you as
|
||
|
|
an E_USER_NOTICE for a while now.
|
||
|
|
|
||
|
|
2.2 HTMLPurifier_ConfigSchema_Interchange
|
||
|
|
|
||
|
|
Member variable $namespaces was removed.
|
||
|
|
|
||
|
|
2.3 HTMLPurifier_ConfigSchema_Interchange_Id
|
||
|
|
|
||
|
|
Member variable $namespace and $directive removed; member variable $key added.
|
||
|
|
Any method that took $namespace, $directive now takes $key.
|
||
|
|
|
||
|
|
2.4 HTMLPurifier_ConfigSchema_Interchange_Namespace
|
||
|
|
|
||
|
|
Removed.
