* Don't use JSON to send the result of `ipcRenderer.sendSync`.
- Change the return type of AtomViewHostMsg_Message_Sync from `base::string16`
to `base::ListValue`
- Adjust lib/browser/api/web-contents.js and /lib/renderer/api/ipc-renderer.js
to wrap/unwrap return values to/from array, instead of
serializing/deserializing JSON.
This change can greatly improve `ipcRenderer.sendSync` calls where the return
value contains Buffer instances, because those are converted to Array before
being serialized to JSON(which has no efficient way of representing byte
arrays).
A simple benchmark where remote.require('fs') was used to read a 16mb file got
at least 5x faster, not to mention it used a lot less memory. This difference
tends increases with larger buffers.
* Don't base64 encode Buffers
* Don't allocate V8ValueConverter on the heap
* Replace hidden global.sandbox with NodeBindings::IsInitialized()
* Refactoring: check NodeBindings::IsInitialized() in V8ValueConverter
* Refactor problematic test to make it more reliable
* Add tests for NaN and Infinity
* add cause property to exception in callFunction
* update exceptionToMeta function
* add sender argument
* and cause property to return value
* update exception convert in metaToValue function
* add from and cause properties to the exception error
* unit test for remote exception
- Create a function that accepts BrowserWindow options and generates a suite
that contains the renderer-specific tests.
- Run the function twice to execute the tests with and without sandbox option.
See the fixed issue for the context. This pulls in a vendored copy of Node that includes the described patch.
Fixes#8358
Test Plan: Built Electron and verified it loaded the sample app correctly and that the module wrapper is the new one by viewing Node's source code in the Blink Inspector.
Added specs and tested with `npm test -- --grep "global variables"`
