<p>Hello all.</p>
<p>I am currently working on removing a piece of internal code called "Flextype" and reorganizing the stackless library. This will involve splitting it into a builting module, _stackless, and a .py module, stackless.py.</p>
<p> </p>
<p>One of the things I want to do is to remove functionality that I think is probably not relied upon, in the C api:</p>
<p> </p>
<p>certain C api functions that are methods on channes and tasklets, will currently work in a virtual way. This is best explained by an example:</p>
<p> </p>
<p>if PyChannel_Send(c, d) is called with an instance of PyChannelType, then an internal C function is invoked as expected.</p>
<p>However, if c is an instance of an inherited type, one that overrides "send", then PyChannel_Send(c, d) will actually behave as if "c.send()" had been called from python code. It will invoke the overriddedn "send" function.</p>
<p> </p>
<p>Originally, the idea was that frameworks would perhaps replace the standard classes with subclasses, and still want to pass these through to C code that would work exactly as python code.</p>
<p> </p>
<p>However, this is an unlikely scenario, IMHO. Also, this sort of behaviour is very unusual in a pythonesque API: PyList_Append(l, a) is _not_ the same as calling "l.append(a)", because a subclass' "append" method won't be invoked.</p>
<p> </p>
<p>Are there any objections to me removing this fringe functionality?</p>
<p> </p>
<p>In other news, I'll be removing the modules' __tasklet__ and __channel__ attributes. These are documented to represent the actuall classes created when channels and tasklets are created using the C api and the python functions. However, this is incorrect.
These attributes are settable and gettable, but otherwise not used anywhere! Which shows how useful they are.</p>
<p> </p>
<p>Cheers,</p>
<p> </p>
