Subject: blink_local_frame.patch
|
|
|
|
According to electron/electron#3699, it is unreliable to use |unload|
|
|
event for process.exit('exit'), so we have to do that in
|
|
willReleaseScriptContext.
|
|
|
|
However Chromium then disallowed scripting in willReleaseScriptContext
|
|
in https://codereview.chromium.org/1657583002, and crash will happen
|
|
when there is code doing that.
|
|
|
|
This patch reverts the change to fix the crash in Electron.
