7. Caching
HTML Purifier generates some cache files to speed up its execution. For
maximum performance, make sure that library/HTMLPurifier/DefinitionCache/Serializer
is writeable by the webserver.
HTML Purifier generates some cache files (generally one or two) to speed up
its execution. For maximum performance, make sure that
library/HTMLPurifier/DefinitionCache/Serializer is writeable by the webserver.
If you are in the library/ folder of HTML Purifier, you can set the
appropriate permissions using:
chmod -R 0755 HTMLPurifier/DefinitionCache/Serializer
If the above command doesn't work, you may need to assign write permissions
to all. This may be necessary if your webserver runs as nobody, but is
not recommended since it means any other user can write files in the
directory. Use:
chmod -R 0777 HTMLPurifier/DefinitionCache/Serializer
You can also chmod files via your FTP client; this option
is usually accessible by right clicking the corresponding directory and
then selecting "chmod" or "file permissions".
Starting with 2.0.1, HTML Purifier will generate friendly error messages
that will tell you exactly what you have to chmod the directory to, if in doubt,
follow its advice.
If you are unable or unwilling to give write permissions to the cache
directory, you can either disable the cache (and suffer a performance
hit):
$config->set('Core', 'DefinitionCache', null);
Or move the cache directory somewhere else (no trailing slash):
$config->set('Cache', 'SerializerPath', '/home/user/absolute/path');

@ -9,6 +9,50 @@ NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
. Internal change
==========================
2.0.1, released 2007-06-27
! Tag auto-closing now based on a ChildDef heuristic rather than a
manually set auto_close array; some behavior may change
! Experimental AutoFormat functionality added: auto-paragraph and
linkify your HTML input by setting %AutoFormat.AutoParagraph and
%AutoFormat.Linkify to true
! Newlines normalized internally, and then converted back to the
value of PHP_EOL. If this is not desired, set your newline format
using %Output.Newline.
! Beta error collection, messages are implemented for the most generic
cases involving Lexing or Strategies
- Clean up special case code for <script> tags
- Reorder includes for DefinitionCache decorators, fixes a possible
missing class error
- Fixed bug where manually modified definitions were not saved via cache
(mostly harmless, except for the fact that it would be a little slower)
- Configuration objects with different serials do not clobber each
others when revision numbers are unequal
- Improve Serializer DefinitionCache directory permissions checks
- DefinitionCache no longer throws errors when it encounters old
serial files that do not conform to the current style
- Stray xmlns attributes removed from configuration documentation
- configForm.php smoketest no longer has XSS vulnerability due to
unescaped print_r output
- Printer adheres to configuration's directives on output format
- Fix improperly named form field in ConfigForm printer
. Rewire some test-cases to swallow errors rather than expect them
. HTMLDefinition printer updated with some of the new attributes
. DefinitionCache keys reordered to reflect precedence: version number,
hash, then revision number
. %Core.DefinitionCache renamed to %Cache.DefinitionImpl
. Interlinking in configuration documentation added using
Injector_PurifierLinkify
. Directives now keep track of aliases to themselves
. Error collector now requires a severity to be passed, use PHP's internal
error constants for this
. HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
much easier selective embedding of configuration values
. Doctype objects now accept public and system DTD identifiers
. %HTML.Doctype is now constrained by specific values, to specify a custom
doctype use new %HTML.CustomDoctype
. ConfigForm truncates long directives to keep the form small, and does
not re-output namespaces

WHATSNEW
View File

@ -1,7 +1,12 @@
HTML Purifier 2.0 is the culmination of two major architectural changes.
The first is Tidy, which enables HTML Purifier to both natively support
deprecated elements and also convert them to standards-compliant
alternatives. The second is the Advanced API, which enables users to
create new elements and attributes with ease. Keeping in line with a
commitment to high quality, there are also five esoteric bug-fixes and a
plethora of subtle improvements that enhance the library.
The 2.0.1 release introduces a number of stability and usability fixes,
as well as a number of (disabled by default) experimental features. The
security-minded should note that a reflected XSS vulnerability was patched
in smoketests/configForm.php; if you cannot upgrade immediately, please
delete that file (if that directory is not publically accessible, there
is no security risk). The maintenance changes include more helpful file
permissions errors, internal newline normalization, reordered includes
to prevent a missing class definition in some setups, and better cache
revision and id handling. The two experimental features are auto-formatting
(auto-paragraphing and linkification) and error collection, these can
be enabled with %AutoFormat.AutoParagraph, %AutoFormat.Linkify and
%Core.CollectErrors respectively.
