To be able to wrap the devtools API namespaces, this patch applies the
following changes:
- fix: Prevent Proxy violation exception on the read-only/non-configurable devtools property
by using an empty object with the `chrome` API object as its prototype
as the root Proxy target (the Proxy instances returned for the
`chrome` API object) and add a related test case.
- fix: Added support for a new `singleCallbackArg` metadata property,
which prevents devtools.panels.create to resolve an array of
parameters (See the related Chromium issue at
https://bugs.chromium.org/p/chromium/issues/detail?id=768159)
and add the related test cases.
- test: Changes to the test case related to proxy getter/setter behavior
on non wrapped properties:
in the "deletes proxy getter/setter that are not wrapped" test case from
the "test-proxied-properties.js" test file, we ensure that when a
getter/setter is called for a "non-wrapped" property, the getter/setter
is going to affect the original target object, unfortunately this in
not true anymore for the root object (the `chrome` API object) because
we are using an empty object (which has the `chrome` API object as its
prototype and it is not exposed outside of the polyfill sources)
as the target of the Proxy instance related to it,
this change to the target of the Proxy has been needed to prevent the
TypeError exception raised by the Proxy instance when we try to access
the "devtools" property (which is non-configurable and read-only on the
`chrome` API object).
* Lock version of gruntify-eslint (and grunt-replace)
The current repository is compatible with gruntify-eslint 3.1.0.
`*` resolves to version 4.0.0., which bumps its eslint dependency
from 3.x to 4.x, which in turn causes linting errors.
To get the default check-out to pass, lock the dependencies to
known-compatible versions.
* Bump gruntify-eslint to 4.0.0 + fix lint error
Bump gruntify-eslint to 4.0.0, which depends on eslint ^4.0.0,
and fix the lint error that appeared.
This patch introduces on top of #17 some minor changes from the
review comments, in particular:
- do not replace require("../filename") to include the api-metadata.json
(restored the original '{/* include("...") */}' placeholder)
- raise an appropriate error message when the source file is used
by mistake (or the "dist/" file has not been built correctly).
- set the generated UMD wrapped module as the package.json main
entrypoint
- do not include api-metadata.json and src dir from the files included
in the published npm package
- run both build and test npm scripts on prepublish
This addresses [issue 7] by making it possible for users to run:
```sh
npm install webextension-polyfill
```
and download a module that they can use with a bundler as follows:
```js
import browser from 'webextension-polyfill';
```
Also, add a [prepublish script] so that users who clone the repo don't
need to run `grunt` manually. In addition, specify [files] in
package.json so that this module can be published to npm without
including miscellanea. This can be verified by running:
```sh
npm pack && tar -tvf webextension-polyfill-0.1.0.tgz
```

- if the a browser global already exists, it should not be overridden
- use Object.defineProperty on the wrapped browser global
(and test "has" for cached properties)
- delete a property defined with Object.defineProperty
- methods that are not wrapped are proxied correctly
- the special onMessage wrapper should not wrap a listener that is not
a function
- test that a returned rejected Promise on the onMessage listener
is turned in the parameter of the sendResponse callback
