[Gnash-commit] [bug #42395] No respons from panopticlick site when gnash is activated

[Nutchanon Wetchasit]

Follow-up Comment #3, bug #42395 (project gnash):

I've created HTML/Flash file (using libming's makeswf) to emulate what
Panopticlick's Flash file do, by assigning Array return value from
`TextField.getFontList()` to a variable named `fontlist` inside root movie.
Then access it from JavaScript via `GetVariable()`, using slash-colon
variable
path notation.

When running `fontlist.html` on browser with Adobe Flash Player

JavaScript calls Flash's GetVariable: OK (returned type string)

After 3 sec, you'd see that font list is passed to JavaScript correctly as
String.

When running `fontlist.html` on browser with current Gnash 0.8.11dev git
<http://i.imgur.com/XNk6E5E.png>:

JavaScript calls Flash's GetVariable: Failed (returned type object)
Value: null


After 3 sec, you'd see that the value passed to JavaScript is `null` instead
of font list string.

This is what appeared in Gnash debug log:

68 ACTIONSCRIPT ERROR: The 'var whatever' syntax in timeline context is a
no-op.
68 TRACE: Fetching list of available fonts...
69 ACTIONSCRIPT ERROR: ActionCallMethod: Function requiring gnash::TextField*
as 'this' called from gnash::as_object* instance.
69 TRACE: Font listing: undefined



Test Flash/HTML file, source code, build script, full text output, 
full debug logs and screenshots of both cases are attached (fontlist.zip).

Gnash: 0.8.11dev (git 88f86a3 19-Aug-2015) NPAPI
Adobe Flash Player: 11.2 r202 (11.2.202.491) NPAPI binary
