You should not assume that a WebProcessProxy has a websiteDataStore when it launches. The WebsiteDataStore gets set later. I am unsure why the GTK port needs to know about the WebsiteDataStore to figure out the launch parameters of the WebProcess. You either need to stop doing that or you need to stop delaying the setting of the WebsiteDataStore on the GTK port. I would not recommend the latter option since it is bad for perf and it would make your port different from others.

Michael, Carlos, any idea?

Odd, every port used to pass applicationCacheDirectory via Initialization parameters, and now pass it later via WebsiteDataStore parameters. For some reason, GTK passes it with the launchParameters. Hopefully, that code can be refactored to do whatever works needs to be done with the applicationCacheDirectory happen later, after launch.

[Michael Catanzaro]

So the problem is these two lines of code in WebProcessProxy::platformGetLaunchOptions?

websiteDataStore().resolveDirectoriesIfNecessary();	    launchOptions.extraInitializationData.set("applicationCacheDirectory", websiteDataStore().resolvedApplicationCacheDirectory());

It's there to be used in bubblewrapSpawn() in BubblewrapLauncher.cpp. Patrick might know why it's done this way. (Why is it different from other website data locations?)

I am confused why you're not returning early here:
void WebProcessPool::didReachGoodTimeToPrewarm()
{
    if (!configuration().isAutomaticProcessWarmingEnabled() || !configuration().processSwapsOnNavigation() || usesSingleWebProcess())
        return;

processSwapsOnNavigation should be disabled for GTK port AFAIK.

In any case, having configuration().isAutomaticProcessWarmingEnabled() return false on GTK port for now would fix your crashes I believe. Process pre-warming is the only case where we do not know which data store to use upon launch.
