Subject: Revert "Remove ContentRendererClient::ShouldFork."
|
|
|
|
This reverts the CL at https://chromium-review.googlesource.com/c/chromium/src/+/1812128.
|
|
We use it to force a new renderer process for navigations, and need to start a new renderer process
|
|
for every navigation to keep Node.js working properly. Once Native Modules in the renderer process
|
|
are required to be NAPI or context aware (Electron v11), this patch can be removed.
