turnidge@google.com 0b833d4977 Add support for interrupting an isolate in the vm. Interrupts are 
implemented by extending the existing support for stack overflow
checking in the vm.  When an interrupt is scheduled for an isolate, we
overwrite the isolate's stack limit with a value guaranteed to cause a
stack overflow.

We support multiple kinds of interrupts, encoded in the low bits of
the stack limit.

Add Dart_InterruptIsolate and Dart_InterruptIsolateCallback to the
dart embedding api to allow the embedder to request and handle
interrupts.

Add EXPECT_SUBSTRING(needle, haystack) testing macro.

 2011-12-09 14:11:47 +00:00
sgjesse@google.com 8f1b82458f Improve the event handling for string input stream 
1. The string input stream now calls the data or line handler if there
   is still data available after returning from the data or line
   handler. These callbacks are scheduled on the event loop.

2. The reading of data is now throtteld so that calls to read or
   readLine will not eagerly try to read from the wrapped input
   stream. After each call to read the data handler is installed if
   no more buffered data is available. Also when the data handler
   is called the data handler on the wrapped input stream is
   un-installed if no more data is required for the current data or
   line handler.

One side effect of this change is that just reading from an input
stream obtained from a file is no longer possible. One will have to
set up a data handler callback of some kind before any calls to read
will return data. We can of cause change this to allow synchronous
usage of an input stream obtained from a file (maybe with an optional
argument to openInputStream).

Fixed a related throtteling issue with the chunked input stream.
