* Relanding this. jcampan@chromium.org2009-04-271-1/+2
| | | | | | | | | | | | | | | | | | | The Ole unitialization was failing on one of the Vista build-bot. It is not clear when the Ole initialization is balanced when a CRichEditCtrl is created/destructed. So I now turn it off explicitly. This CL makes sure we unregister our Windows window classes when shut-down. It also balances-out an OLE initialization performed by the CRichEditCTRL. This is necessary for allowing to reload chrome.dll in a process, which is what the browser tests will do.

* Switch MessagePumpForIO to use completion ports on Windows.rvargas@google.com2008-11-071-407/+259
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cleanup the separation between MessagePumpForUI and MessagePumpForIO, and convert the latter to use Completion Ports instead of MsgWaitForMultipleobjects to sleep when idle. Remove all traces of Windows messages from MessagePumpForIO, remove the transitional API of completion port notifications and remove WatchObject API. Modify all callers of RegisterIOHandler so that they are no longer using RegisterIOContext, and also handle properly the new semantics of completion ports (notifications even when the IO completes immediately). Add a new interface to allow proper cleanup of disk cache (to replace code that was waiting for pending APCs from the destructor). Add a way for the message pump to perform cleanup of abandoned IO.

| | | | | | | | | | | | | | | | | | | | | | | | | | which was an issue with the browser UI thread entering a tight loop at times. The thread inputs of the browser UI thread and the plugin thread are attached due to the parent child relationship between the windows. As a result at times the MsgWaitForMultipleObjectsEx API returns the fact that there are messages in the queue (mouse messages). The subsequent peek fails to return any messages causing us to enter a loop for a while. This also happens when the plugin has capture and just before it releases capture, some mousemoves end up in the browser ui thread causing a tight loop. The fix is to check if there are mouse messages in the queue by invoking GetQueueStatus and attempting to peek them out with PM_NOREMOVE. If this fails we call WaitMessage to block until the next message. The other fix is to return true from ProcessNextWindowsMessage if PeekMessage returns false and there were sent messages in the queue, as this is as expected. This will ensure that we go back up and peek again instead of calling MsgWaitForMultipleObjectsEx again.

This involved recording the intended fire time of PostDelayedTask on the Task object so that it can be used to properly determine the delay passed to the StartTimer call.

| | | | | | | | | | | | | | | | | being run within shell32, which was causing our kHaveWorkMsg to get dispatched. However, because that was occuring outside the context of a MessagePump::Run call, the handler for kHaveWorkMsg was returning early. Unfortunately, this means that it was failing to reset the have_work_ sentinel to 0. Because of that future calls to ScheduleWork would always be a no-op (as they return early when have_work_ is already set to 1). The proper fix is to just re-order the calls so that ProcessPumpReplacementMessage always runs in response to kHaveWorkMsg, but we still suppress calling DoWork until we are inside MessagePump::Run.

MessageLoop. A MessageLoop now has a MessagePump. This will make it possible to port the MessagePump interface to other platforms as well as to use an IO completion port for our worker threads on Windows. Currently, there is only MessagePumpWin, which attempts to preserve the pre-existing behavior of the MessageLoop. API changes to MessageLoop: 1. MessageLoop::Quit means return from Run when the MessageLoop would otherwise wait for more work. 2. MessageLoop::Quit can no longer be called outside the context of an active Run call. So, things like this: MessageLoop::current()->Quit(); MessageLoop::current()->Run(); are now: MessageLoop::current()->RunAllPending(); 3. MessageLoop::Quit can no longer be called from other threads. This means that PostTask(..., new MessageLoop::QuitTask()) must be used explicitly to Quit across thread boundaries. 4. No protection is made to deal with nested MessageLoops involving watched objects or APCs. In fact, an assertion is added to flag such cases. This is a temporary measure until object watching and APC facilities are removed in favor of a MessagePump designed around an IO completion port. As part of this CL, I also changed the automation system to use an IPC::ChannelProxy instead of an IPC::Channel. This moves the automation IPC onto Chrome's IO thread where it belongs. I also fixed some abuses of RefCounted in the AutomationProvider class. It was deleting itself in some cases! This led to having to fix the ownership model for AutomationProvider, which explains the changes to AutomationProviderList and so on. git-svn-id: svn://svn.chromium.org/chrome/trunk/src@928 0039d316-1c4b-4281-b951-d872f2087c98
