Bug 100664 – Web Inspector: adds isOwnProperty to remote protocol

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.16 (KHTML, like Gecko) Chrome/24.0.1305.3 Safari/537.16

Steps to reproduce the problem:
I'm writing an automated testing tool, and I'd like to fetch all the properties of an object, and then display the properties that come from the object's prototype with a different format.

This can be achieved by calling Runtime.getProperties [1] with ownProperties set to true, and then call it again with ownProperties set to false. However, that's more inefficient, and a bit harder to implement than a single call to Runtime.getProperties.

What is the expected behavior?
I would like to see a boolean ownProperty in PropertyDescriptor[2].

What went wrong?
I currently need two calls to Runtime.getProperties [1], and I need to merge the results in them. PropertyDescriptor [2] does not have an ownProperty attribute, which would make my life super-easy.

Did this work before? No 

Chrome version: 24.0.1305.3  Channel: dev
OS Version: OS X 10.8.2

[1] https://developers.google.com/chrome-developer-tools/docs/protocol/1.0/runtime#command-getProperties
[2] https://developers.google.com/chrome-developer-tools/docs/protocol/1.0/runtime#type-PropertyDescriptor

I'm guessing that other developers would like this change too. The extra code is not a big deal in my case, but I think changing the Webkit remote debugging protocol would make it more useful.

isOwnProperty: o === object,

also, since this property is optional, you should only add it when it is true. I.e. create an object and optionally add isOwnProperty there.

drop these 2 lines

==, surround with " "
property.name == bar

{ bar: "cde" };

function fail(message)
{

drop this

Do not use {} around single line blocks

return fail() ...

... also, you don't need this branch. Let the test time out in case it fails.
