Comment on SSL support in asynchat.async_chat by Jean-Paul Calderone

@Giampaolo: It seems that bug was deemed important enough to include twice. ;) The one in ssl.py does appear to be fixed, but the one in _ssl.c is still there: see the do loop in PySSL_SSLRead at http://svn.python.org/view/*checkout*/python/trunk/Modules/_ssl.c?revision=82210&content-type=text/plain

@jp: what python version are you using?
Python 2.6.6 should already include a fix for that: http://bugs.python.org/issue3890

Unfortunately, you may not find this as useful as you would have expected. The ssl module does not support non-blocking reads:

>>> import socket
>>> import time
>>> import ssl
>>> s = ssl.wrap_socket(socket.socket())
>>> s.connect(('localhost', 8443))
>>> s.send('GET /async.rpy HTTP/1.1\r\n\r\n')
27
>>> s.setblocking(False)
>>> a = time.time(); s.recv(1024); b = time.time()
'HTTP/1.1 200 OK\r\nTransfer-Encoding: chunked\r\nDate: Thu, 02 Sep 2010 11:51:03 GMT\r\nContent-Type: text/html\r\nServer: TwistedWeb/10.1.0+r29954\r\n\r\n4c\r\nSorry to keep you waiting.\r\n0\r\n\r\n'
>>> print b - a
4.13403391838
>>>

Even worse than the fact that it blocks is the fact that it is busy looping while it does so. Expect to see 100% CPU when using this approach any time there's a network hiccup or someone decides to DoS your service. :(

Comment on Simple Output Buffering in Python by Jorge Vargas

Hi,

I just stumble upon this very same problem, and I find your class excellent as it solves exactly what I'm trying to do.

Just one minor correction to this article. sys.__stdout__ , etc. Will keep the reference to the original stdout, similar variables exists for the other streams.

So you don't really lose those references and you can replace them afterwards.

Another unhappy thing is that your module is GPL3 which prevents me from using it in this particular codebase therefore I'm afraid I'm going to have to just learn from it :(

Anyway great find and thank you.

Comment on Cross-platform file locking support in Python by Rick Harris

Evan, thanks for posting this, was a big help. I ended up using your FileLock to build a file-based counting semaphore which is used by http://github.com/rconradharris/filecache.

Great job!
