- Move frame attachment from RenderFrameCreated to
DidCommitProvisionalLoad. This has a number of advantages:
- Significantly reduces the frequency of disconnects by avoiding
the GetInterface/DidCommitNavigation race condition.
- Stops connecting temporary frames (created during cross-origin
navigation), making callback behavior more consistent.
- Split frame detach and destruction notifications into separate
callbacks. OnFrameDetached now reflects a potentially recoverable
state. Add a new OnFrameDestroyed callback for the unrecoverable
destruction state.
- Use ResetWithReason to report intentional browser side disconnects of
existing Mojo connections. Don't retry for those disconnects.
- Add set_disconnect_with_reason_and_result_handler in Chromium/Mojo to
expose the MojoResult code for failed connections, allowing
identification of connections that are intentionally unbound on the
browser side.
- Optimize initial reconnect delay for known disconnect cases such as
navigation-related and bfcache changes.
- Remove connection timeout and increase total connection deadline by
100% to further reduce crash rates on slower machines.
- Only fail fatally for main frames (not sub-frames) in cases where the
connection fails or disconnects for unknown reasons.
- Improve connection debug logging when running with
`--enable-logging --vmodule=*frame*=1 --log-file=C:\temp\log.txt`
