Abstract

A computer-implemented method executed by at least one processor performs operations for a web browser running a browser process and at least one renderer process on a computing system. The method includes identifying a webview tag in a web page, the web page being associated with the at least one renderer process. The method also includes forking another renderer process responsive to identifying the webview tag, generating a mapping between the at least one renderer process and the other renderer process at the browser process, and using the browser process as an intermediary for communications between the at least one renderer process and the another renderer process based on the mapping.

Claims20

Dependent claims

A computing device comprising:

at least one processor;
a memory;
a display device;
and
instructions, stored in the memory, that when executed by the at least one processor cause the computing device to perform operations comprising:
running a browser process, the browser process generating data used to display a window on the display device, and
running one or more renderer processes, the renderer processes being forked and controlled by the browser process, one of the renderer processes being an embedder process associated with a guest process, the guest process being another one of the renderer processes and the guest process being unaware of the embedder process,
wherein the renderer processes have storage isolation with respect to each other and each renderer process that is not the guest process has a respective content area in the window, a content area displaying output generated by a respective rendering process, and
wherein the browser process acts as an intermediary for communications between the guest process and the embedder process so that output from the guest process is included in the content area for the embedder process while maintaining storage isolation.

6 more elements

A computer-implemented method executed by at least one processor performing operations for a web browser running a browser process and at least a first renderer process on a computing system, the method comprising:

identifying a tag in a first web page that causes the web browser to embed a second web page within the first web page, the first web page being displayed in a tab associated with the first renderer process;
forking a second renderer process responsive to identifying the tag, wherein the first renderer process and the second renderer process have storage isolation;
generating a mapping between the first renderer process and the second renderer process at the browser process, the second renderer process being unaware of the mapping or the existence of the second renderer process;
and
using the browser process as an intermediary for communications between the first renderer process and the second renderer process based on the mapping, so that output from the second renderer process is included in the tab for the first renderer process while maintaining storage isolation.

2 more elements

A non-transitory computer-readable medium containing instructions executable by at least one processor, the instructions causing at least a first renderer process and a browser process running on a computing system to perform operations comprising:

identifying a tag in a first web page that embeds a second web page within the first web page, the web page being displayed in a tab associated with the first renderer process;
forking a second renderer process responsive to identifying the tag, wherein the first renderer process and the second renderer process have storage isolation;
generating a mapping between the first renderer process and the second renderer process at the browser process, the second renderer process being unaware of the mapping or the existence of the second renderer process;
and
using the browser process as an intermediary for communications between the first renderer process and the second renderer process based on the mapping, so that output from the second renderer process is included in the tab for the first renderer process while maintaining storage isolation.
