> Jędrzej, I have a question: since the 'Object' property of the global object
can be modified and propertyFlags() could be called after that, isn't
"dangerous" to get the Object constructor at this point?
It is. There should be a "fixme" apparently it was lost somehow. Thanks for the
review.
> I had a similar situation for isArray(), and ended up extracting the Array
constructor and prototype just after the global context was created in
QScriptEnginePrivate (C++) ctor, storing them in member variables.
Yes I think keeping a reference to the prototype and to the constructor is a
good solution (and maybe only one as JSC doesn't keep original values).
The same issue is in the QSV::isError(), QSV::isRegExp() functions, I think it
will be for an other too. Moreover the QtScript API permits to change global
object and in the same time it use it a lot.
>From architectural point of view I believe that we should create separate
class/struct that represent Original Global Object, It should be created at
QScriptEnginePrivate creation time and it should be private for the QSEP.
I will repost the patch with the fixme comment.
