Scripting MIME Types application/ecmascript, application/javascript not viewable

• Component: WebCore JavaScript
• Status: RESOLVED FIXED

[Sierk Bornemann]

IESG approved registration of the application/ecmascript and related media types.

See:
IANA|Text Media-Types, http://www.iana.org/assignments/media-types/text/
IANA|Application Media-Types, http://www.iana.org/assignments/media-types/application/

RFC 4329 "Scripting Media Types" defines valid MIME-Types for ECMAScript and JavaScript and marks which ones are invalid. See ftp://ftp.rfc-editor.org/in-notes/rfc4329.txt for details.

The use of the former used MIME Types text/ecmascript, text/javascript and text/x-javascript is discouraged (marked obsolete) in favour of application/ecmascript (ECMAScript) and application/javascript (JavaScript).

Web browsers should recognize and handle these new MIME Types correctly.

According to http://webkit.org/blog/?p=93, please fix this bug as soon as possible. It would be great, if the next Version of Safari will handle the MIME type of JavaScript/ECMAScript right, wouldn't it?

I believe this was fixed in r18843:

It seems like the static list of JavaScript MIME types used in WebCore/html/HTMLScriptElement.cpp could be used in these classes as well:

WebCore/dom/DOMImplementation.cpp
WebCore/platform/MimeTypeRegistry.cpp

In DOMImplementation::isTextMIMEType().

> WebCore/platform/MimeTypeRegistry.cpp

In initialiseSupportedNonImageMimeTypes().

If you are of the opinion, the bug is fixed and can be closed, close it.

The test works, but Safari won't display the source of the application/ecmascript file in the browser (like it would with application/x-javascript).

I'd like to leave this bug open to address issues from Comment #4 and Comment #5.

Bearing in mind the next release of MacOSX 10.5 and rumors of the shortcoming MacOS 10.4.9, I would be very happy, if this bug would be fixed in the then shipped Safari Web Browser.
Please fix the outstanding issues with special regard to Comment #4, Comment #5 and Comment #9, which seem to block this bug here from being fixed.

[David Kilzer (:ddkilzer)]

The methods from Comment #4 should move to WebCore/platform/MimeTypeRegistry.cpp.
