Title:
Improvements to working with the default WebContext to support single-
process mode
Status in Oxide Webview:
Fix Released
Bug description:
Originally, I intended for the default WebContext (the one that's
created automatically for WebView's that don't have an explicit
context set) to be hidden away from QML, with some basic
configurability proxied via the "Oxide" singleton. If developers
wanted to use advanced features, they could create an explicit
WebContext.
However, there are going to be some issues with this approach:
- We're adding more and more stuff to WebContext, and this stuff needs
to be duplicated.
- Due to some limitations in Chromium, multiple WebContext's do not
work correctly in single process mode because all RenderView's run in
the same in-process RenderProcess, which maps to a single
BrowserContext (and hence WebContext). The implication of this is that
any IPC messages from any views that are destined for a specific
WebContext will end up always being delivered to the first WebContext,
which might not be the right one. If we want to support a single
process mode, we don't want developers having to create additional
WebContext's in order to use things like user scripts.
We should make the default WebContext singleton available to QML.
Currently, WebContext.dataPath and WebContext.cachePath are construct-
only properties because they can't be changed once the BrowserContext
has been created internally. If we are going to expose the default
WebContext singleton to QML, we will need to lazy construct the
BrowserContext in order to be able to change dataPath and cachePath on
a fully-constructed (but not yet in-use) WebContext.
