PyPy doesn't, Unladen Swallow won't.

I think this is fine too. :)
If 'block' is True then return 'size' bytes, unless the end of the
file/stream is reached; if 'block' is False then return up to 'size'
bytes, without blocking. The blocking

Hi all,
I have a few questions about validating SSL certificates. From what I
gather, this validation occurs in the OpenSSL code called from _ssl.c. Is
this correct?
Also, I have looked through the docs and code, but haven't been able to
figure out exactly what is included in certificate

intuitive API.
Well, I realized this as

It really depends on what these questions are. If your question is

If you have a thread dedicated to reading from that

peek() doesn't fit into the abstraction since it doesn't even exist on raw
streams.

What's convenient about it? Seems to me it's the
opposite, since you can't just bail out if it
fails, but have to decref the reference you
thought it was going to take care of for you.

This proposal looks reasonable to me. Please note that it's too late for 3.1
anyway - we're in release candidate phase. Once you have a patch, you can post
it on the bug tracker.
Thanks I will do that.
