Vista becomes hysterical!
-
My psychic debugging skills tell me a plugin on one of the webpages crashed -- remember, Chrome runs plugins like Flash and Silverlight and Java in their own process. I bet a plugin process crashed (I've seen this many times with both Flash and Silverlight in Chrome), and since the plugin process is named "chrome.exe", Vista reported Chrome as having crashed, even though the main Chrome process was running and even though all the pages were still up.

Kind of hard to do, considering Chrome wasn't around when Vista was released.

Well... you're less wrong. The documentation is pretty specific on what Windows considers an unresponsive program though:
An application is considered to be not responding if it is not waiting for input, is not in startup processing, and has not called PeekMessage within the internal timeout period of 5 seconds.
My response was specific to his statement - "Task manager sends a message to every running process, every 5 seconds" (I had quoted it as well). And I said there's no such thing. The API you linked to comes into picture, only if you are talking about a "Window" (NOT a process - or rather processes that have window(s)). Note that the API is taking in a handle to a window, and not a handle to a process. And when does the window stops responding: hasn't retrieved several messages from the message loop, hasn't peeked to check for messages, etc.,. - Which is essentially what I said in my previous post. What about those processes that have no window?! This API is irrelevant in such cases and therefore cannot be applied for all running processes. Also, this has nothing to do with Task manager sending any message to any process. Added: BTW, I hadn't known that the default timeout for applications to peek for arrival of new messages in the loop were 5 seconds. Thanks, I know it now. :)

Browser plugins run in separate processes, too. My bet is that Flash or some other plugin crashed. You didn't notice it because it was used for an ad or something small on a page.

So, when viewing a typical modern page in Chrome, you can expect up to 20 "Hey, Bub, it's crashed" messages, for all the inlaid advertising cr@p?

To the best of my knowledge, Task Manager has no concept of an unresponsive application for windowless apps. Things like services also have scenarios where they're expected to respond within a timeframe or be killed, but these are largely separate from Task Manager, and completely unrelated to the "unresponsive" indicator displayed in that applet.

Mostly, yes. The "unresponsive" flag is set by the window manager, based on the criteria i quoted above. Task Manager reads it. Task manager can trigger messages for an application window in response to certain user requests, but it does not do so arbitrarily. John had the timeframe right (5 sec) - the criteria is based on time, not number of messages posted. You correctly surmised that Windows doesn't send messages for the specific purpose of detecting this. And you were closer to the method by which Windows handles this... though strictly speaking Windows doesn't really do much beyond setting that flag and painting the window (pre-XP) or displaying a placeholder window (XP and later) - if the user tries to close the placeholder, then they get the choice of terminating the process it belongs to or continuing to wait.

Yesterday evening I was browsing internet using Chrome. I was opened several tabs enjoying some nice turboprop airplanes pictures when suddenly the Vista’s crash window shows up. You know – this one which reads something like: “The Google Chrome application is not responding and need to be shut down…do you want to restart the program?…” or something similar. So I closed the error prompt and…continue with browsing the current page without any problems! The Chrome doesn’t crashed, there was no crashed tabs…everything was just okay! So I’m puzzled WTF was that? Either Vista for some reasons needs to fake Chrome crashes or there is the following source code somewhere inside the last updates:
private void CHandleWithCompetitors::Hook CurrentBrowser(LPDISPATCH *browserRef)
{
If(GetCurrentBrowser(browserRef) == GOOGLE_FUCKING_CHROME)
{
If(!BrowserTryCrash(browserRef))
{
throw CInternalEx(“BrowserUncrashableExseption”);
}
}

Exactly! Therefore my reply to John. So, I woke up the native lang beast in you, Shog? :)
