      jscript: Inline prop_put.
      jscript: Inline prop_get.
      jscript: Inline invoke_prop_func and invoke PROTREFs using their vtbl method.
      jscript: Inline delete_prop.
      jscript: Use mandatory methods in the object vtbl to operate on props found

[PATCH v2 03/11] jscript: Use mandatory methods in the object vtbl to operate on props found by name.

[Gabriel Ivăncescu]

From: Gabriel Ivăncescu

is_dispex_prop_id will be more useful later when we'll also have indexed
props with their own vtbl, for now it avoids DISPID_VALUE.

[PATCH v2 11/11] jscript: Remove PROP_IDX dispex props by handling them in object prop methods.

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

I've sent new version with using object vtbl and mandatory methods—note how we can now override all props, not just indexed props. That's not just to get rid of special checks in callers, but also because it will be needed for those "async" props as outlined above, so it's going to be needed anyway.

`this_obj` useful only for functions, which are implemented in jscript, so they don't go through this interface, right?

Yes the new "proxy functions" on jscript side don't use this interface
(and so, neither accessors). But I meant using it on objects'
DISPID_VALUE. Simplest example is probably imagine calling InvokeEx on a
jscript proxy. It will end up in jsdisp_call_value which needs to
forward it to the mshtml object.

Of course, the interface could probably be simplified, but we'll still
have to pass the "this" pointer separately.

Why would we ever want to pass it to any MSHTML object?

Oh, I see what you mean. You want to hardcode on jscript the fact that
mshtml does not make use of it for DISPID_VALUE? I didn't check this,
but it seems plausible and what you meant, right?

I was just trying to forward everything *as if* InvokeEx was called
directly on the mshtml object itself (like in pre IE8 modes), i.e.
making it "generic". But if that's not a requirement I'll re-evaluate.

From a quick look, it does seem like it's not used, though. So in
retrospect, I can probably remove it, though I'll need to test to make sure.

Yes, kind of, but I wouldn't call it 'hardcoding'. MSHTML may have properties with `DISPID_VALUE`, but they should have no reason to deal with 'this' argument; it's meaningful only for functions and having functions implemented in jscript is a design decision.

Do you intend to use this interface on pre IE8 as well?

Nope, the only thing I extend to IE8 and below are the cycle collection
integration, since it helps as well (with only like a single extra line
of code).

What I meant is that, in theory, InvokeEx (on mshtml side!) does receive
a "this" argument, in IE8 and below, simplest case is when called from C
code. Even though no mshtml object seems to make use of it. So I wanted
to keep it generic and play it safe and thus "pass the same thing" if a
jscript proxy receives that "this" arg, but if it's not required I'll
just get rid of it. :)

BTW for this MR, I already got rid of "on_put" now in a patch, since we
override the prop_put on Arrays. That's an example of how the jscript
proxy would work as well, except it would be at the top of the function
before it's forwarded.

It's better now, but I still can't review it on its own while MSHTML bindings design is so blurry. I think it will be better to have a bit more complete prototype for the context before upstreaming its pieces.

Well this MR technically isn't about that, is it? It's for indexed props
and Typed Arrays (which will come immediately now).

And having something like this is clearly the most "extensible" since it
allows overriding every prop's behavior.

Should I rewrite my mshtml-integration patches to use this now? I was
actually waiting for it to go upstream first so I only have to do it
once in whatever shape it's in—I'm not attached to any particular
method, as long as it works.

[Jacek Caban (＠jacek)]

> Well this MR technically isn't about that, is it?

I think it should, see my earlier comments.

There are many solutions, we're looking for the one that fits our needs best. I can't review that aspect in its current form and I don't share your confidence about it.
