* Reduce header dependencies in base/phajdan.jr@chromium.org2009-06-031-3/+0
| | | | | | | | Also adds more explicit #includes for needed things. Review URL: http://codereview.chromium.org/118162 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@17479 0039d316-1c4b-4281-b951-d872f2087c98
* POSIX: allow WaitableEvents to be deleted while watching them.agl@chromium.org2009-03-261-8/+30
| | | | | | | | | | | | | | | | | | | On Windows, one can close a HANDLE which is currently being waited on. The MSDN documentation says that the resulting behaviour is 'undefined', but it doesn't crash. Currently, on POSIX, one couldn't use WaitableEventWatcher to watch an event which gets deleted. This mismatch has bitten us several times now. This patch allows WaitableEvents to be deleted while a WaitableEventWatcher is still watching them. It applies only to watchers, the usual Wait() and WaitMany() calls still require that all their target be valid until the end of the call. http://crbug.com/8809 Review URL: http://codereview.chromium.org/53026 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@12576 0039d316-1c4b-4281-b951-d872f2087c98

* WaitableEvent is the replacement for Windows events. Previously in the code, ↵agl@chromium.org2009-01-151-8/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | a HANDLE from CreateEvent was used for signaling, both within a process and across processes. WaitableEvent is the cross platform replacement for this. To convert: * HANDLE -> base::WaitableEvent* * ScopedHandle -> scoped_ptr<base::WaitableEvent> * CreateEvent -> new base::WaitableEvent * SetEvent -> base::WaitableEvent::Signal * ResetEvent -> base::WaitableEvent::Reset * ObjectWatcher -> base::WaitableEventWatcher * WaitForMultipleObjects -> static base::WaitableEvent::WaitMany ObjectWatcher remains for Windows specific code. WaitableEventWatcher has an identical interface save, * It uses WaitableEvents, not HANDLEs * It returns void from StartWatching and StopWatcher, rather than errors. System internal errors are fatal to the address space IMPORTANT: There are semantic differences between the different platforms. WaitableEvents on Windows are implemented on top of events. Windows events work across process and this is used mostly for modal dialog support. Windows events can be duplicated with DuplicateHandle. On other platforms, WaitableEvent works only within a single process. In the future we shall have to replace the current uses of cross-process events with IPCs. BEWARE: HANDLE, on Windows, is a void *. Since any pointer type coerces to void *, you can pass a WaitableEvent * where a HANDLE is expected without any build-time errors.

* Provide cross-platform implementation of WaitableEvent for use on Mac and Linux.darin@google.com2008-08-111-2/+15
| | | | | | | | | I gave the file the suffix _generic since it is implemented entirely in terms of other APIs in base. This CL also adds a simple unit test for WaitableEvent, and I switched some code in thread.cc over to using WaitableEvent. git-svn-id: svn://svn.chromium.org/chrome/trunk/src@648 0039d316-1c4b-4281-b951-d872f2087c98
* A basic wrapper for a windows event object that encapsulates the way we ↵darin@google.com2008-08-091-0/+94
often use windows events. This API is not meant to be compatible with ObjectWatcher or MessageLoop::WatchObject. This API is meant to be easily ported to Mac & Linux using a traditional mutex and condition variable pairing. There's nothing to test here since the implementation is such a thin wrapper around Win32 APIs. However, once we go off to implement a posix version, we'll need some tests. git-svn-id: svn://svn.chromium.org/chrome/trunk/src@620 0039d316-1c4b-4281-b951-d872f2087c98
