[New-bugs-announce] [issue29235] Allow profile/cProfile to be used as context managers

[Thane Brimhall]

New submission from Thane Brimhall:

The `enable` and `disable` methods on the profilers fit the description of a context manager very well. The following code:

    pr = cProfile.Profile()
    pr.enable()
    # ... do something ...
    pr.disable()
    pr.print_stats()

Would turn into something like this:

    with cProfile.Profile() as pr:
        # ... do something ...
    pr.print_stats()

The patch for this code would be trivial and backwards-compatible: simply add something like the following lines to the _lsprof.Profiler base class:

    def __enter__(self):
        self.enable()
        return self

    def __exit__(self, exc_type, exc_val, exc_tb):
        self.disable()
