Updated HTML Purifier from 4.6.0 to 4.9.2 with better PHP7 compatibility. Used composer to manage this library. --- vendor/ezyang/htmlpurifier/TODO | 150 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 150 insertions(+) create mode 100644 vendor/ezyang/htmlpurifier/TODO (limited to 'vendor/ezyang/htmlpurifier/TODO') diff --git a/vendor/ezyang/htmlpurifier/TODO b/vendor/ezyang/htmlpurifier/TODO new file mode 100644 index 000000000..1afb33cbf --- /dev/null +++ b/vendor/ezyang/htmlpurifier/TODO @@ -0,0 +1,150 @@ + +TODO List + += KEY ==================== + # Flagship + - Regular + ? Maybe I'll Do It +========================== + +If no interest is expressed for a feature that may require a considerable +amount of effort to implement, it may get endlessly delayed. Do not be +afraid to cast your vote for the next feature to be implemented! + +Things to do as soon as possible: + + - http://htmlpurifier.org/phorum/read.php?3,5560,6307#msg-6307 + - Think about allowing explicit order of operations hooks for transforms + - Fix "<.<" bug (trailing < is removed if not EOD) + - Build in better internal state dumps and debugging tools for remote + debugging + - Allowed/Allowed* have strange interactions when both set + ? Transform lone embeds into object tags + - Deprecated config options that emit warnings when you set them (with' + a way of muting the warning if you really want to) + - Make HTML.Trusted work with Output.FlashCompat + - HTML.Trusted and HTML.SafeObject have funny interaction; general + problem is what to do when a module "supersedes" another + (see also tables and basic tables.) This is a little dicier + because HTML.SafeObject has some extra functionality that + trusted might find useful. See http://htmlpurifier.org/phorum/read.php?3,5762,6100 + +FUTURE VERSIONS +--------------- + +4.9 release [OMG CONFIG PONIES] + ! Fix Printer. It's from the old days when we didn't have decent XML classes + ! Factor demo.php into a set of Printer classes, and then create a stub + file for users here (inside the actual HTML Purifier library) + - Fix error handling with form construction + - Do encoding validation in Printers, or at least, where user data comes in + - Config: Add examples to everything (make built-in which also automatically + gives output) + - Add "register" field to config schemas to eliminate dependence on + naming conventions (try to remember why we ultimately decided on tihs) + +5.0 release [HTML 5] + # Swap out code to use html5lib tokenizer and tree-builder + ! Allow turning off of FixNesting and required attribute insertion + +5.1 release [It's All About Trust] (floating) + # Implement untrusted, dangerous elements/attributes + # Implement IDREF support (harder than it seems, since you cannot have + IDREFs to non-existent IDs) + - Implement (client and server side image maps are blocking + on IDREF support) + # Frameset XHTML 1.0 and HTML 4.01 doctypes + - Figure out how to simultaneously set %CSS.Trusted and %HTML.Trusted (?) + +5.2 release [Error'ed] + # Error logging for filtering/cleanup procedures + # Additional support for poorly written HTML + - Microsoft Word HTML cleaning (i.e. MsoNormal, but research essential!) + - Friendly strict handling of
(block ->
) + - XSS-attempt detection--certain errors are flagged XSS-like + - Append something to duplicate IDs so they're still usable (impl. note: the + dupe detector would also need to detect the suffix as well) + +6.0 release [Beyond HTML] + # Legit token based CSS parsing (will require revamping almost every + AttrDef class). Probably will use CSSTidy + # More control over allowed CSS properties using a modularization + # IRI support (this includes IDN) + - Standardize token armor for all areas of processing + +7.0 release [To XML and Beyond] + - Extended HTML capabilities based on namespacing and tag transforms (COMPLEX) + - Hooks for adding custom processors to custom namespaced tags and + attributes, offer default implementation + - Lots of documentation and samples + +Ongoing + - More refactoring to take advantage of PHP5's facilities + - Refactor unit tests into lots of test methods + - Plugins for major CMSes (COMPLEX) + - phpBB + - Also, a FAQ for extension writers with HTML Purifier + +AutoFormat + - Smileys + - Syntax highlighting (with GeSHi) with 
 and possibly  tags; may be troublesome
+   because regular CSS has no way of uniquely identifying nodes, so we'd
+   have to generate IDs
+ - Explain how to use HTML Purifier in non-PHP languages / create
+   a simple command line stub (or complicated?)
+ - Fixes for Firefox's inability to handle COL alignment props (Bug 915)
+ - Automatically add non-breaking spaces to empty table cells when
+   empty-cells:show is applied to have compatibility with Internet Explorer
+ - Table of Contents generation (XHTML Compiler might be reusable). May also
+   be out-of-band information.
+ - Full set of color keywords. Also, a way to add onto them without
+   finalizing the configuration object.
+ - Write a var_export and memcached DefinitionCache - Denis
+ - Built-in support for target="_blank" on all external links
+ - Convert RTL/LTR override characters to  tags, or vice versa on demand.
+   Also, enable disabling of directionality
+ ? Externalize inline CSS to promote clean HTML, proposed by Sander Tekelenburg
+ ? Remove redundant tags, ex. Underlined. Implementation notes:
+    1. Analyzing which tags to remove duplicants
+    2. Ensure attributes are merged into the parent tag
+    3. Extend the tag exclusion system to specify whether or not the
+    contents should be dropped or not (currently, there's code that could do
+    something like this if it didn't drop the inner text too.)
+ ? Make AutoParagraph also support paragraph-izing double 
 tags, and not
+   just double newlines.  This is kind of tough to do in the current framework,
+   though, and might be reasonably approximated by search replacing double 
s
+   with newlines before running it through HTML Purifier.
+
+Maintenance related (slightly boring)
+ # CHMOD install script for PEAR installs
+ ! Factor out command line parser into its own class, and unit test it
+ - Reduce size of internal data-structures (esp. HTMLDefinition)
+ - Allow merging configurations.  Thus,
+        a -> b -> default
+        c -> d -> default
+   becomes
+        a -> b -> c -> d -> default
+   Maybe allow more fine-grained tuning of this behavior. Alternatively,
+   encourage people to use short plist depths before building them up.
+ - Time PHPT tests
+
+ChildDef related (very boring)
+ - Abstract ChildDef_BlockQuote to work with all elements that only
+   allow blocks in them, required or optional
+ - Implement lenient  child validation
+
+Wontfix
+ - Non-lossy smart alternate character encoding transformations (unless
+   patch provided)
+ - Pretty-printing HTML: users can use Tidy on the output on entire page
+ - Native content compression, whitespace stripping: use gzip if this is
+   really important
