Reviewed by Dan Bernstein.
Add more checks for when a process goes away before we've established a proper connection to it.
* Platform/IPC/mac/ConnectionMac.mm:
(IPC::Connection::receiveSourceEventHandler):
Handle the MACH_NOTIFY_NO_SENDERS and MACH_NOTIFY_SEND_ONCE messages here. Also, once we receive a send
right from the other side, stop listening for the MACH_NOTIFY_NO_SENDERS notification.
* UIProcess/ChildProcessProxy.cpp:
(WebKit::ChildProcessProxy::didFinishLaunching):
Null check the connection identifier.
* UIProcess/Launcher/ProcessLauncher.cpp:
(WebKit::ProcessLauncher::ProcessLauncher):
(WebKit::processLauncherWorkQueue): Deleted.
Get rid of the process launcher queue - we're not doing any blocking work here.
* UIProcess/Launcher/ProcessLauncher.h:
Add a weak factory.
* UIProcess/Launcher/mac/ProcessLauncherMac.mm:
(WebKit::systemDirectoryPath):
Move this before launchProcess().
(WebKit::ProcessLauncher::launchProcess):
Merge createService and connectToService into launchProcess. Also make the following changes:
- Use mach_port_request_notification to get a notification for when our receive right loses all its senders.
This lets us listen for the other process going away before we have a send right for it.
- Use xpc_connection_set_event_handler to listen for errors, so we can detect the process going away before
we've sent a message to it.
(WebKit::connectToService): Deleted.
(WebKit::createService): Deleted.
* UIProcess/Network/NetworkProcessProxy.cpp:
(WebKit::NetworkProcessProxy::didFinishLaunching):
If we failed to launch, call networkProcessCrashedOrFailedToLaunch so we'll unblock any waiting web processes.
* UIProcess/WebProcessProxy.cpp:
(WebKit::WebProcessProxy::didFinishLaunching):
Null check the connection and XPC connection before trying to get its pid.
