Indeed. I should have checked the sources first. Anyway, thanks for info.
Unfortunately, just after fixing above problem, I occurred one really
annoying "feature". When I try to connect to a host/port which doesn't
support SSL connections, I receive an exception which I can't catch. The
traceback looks like this:
File "/usr/lib/python2.4/site-packages/twisted/python/context.py", line
43, in callWithContext
File "/usr/lib/python2.4/site-packages/twisted/internet/default.py", line

File "/usr/lib/python2.4/site-packages/twisted/internet/tcp.py", line 133,
File "/usr/lib/python2.4/site-packages/twisted/internet/abstract.py", line
99, in doWrite
--- <exception caught here> ---

File "/usr/lib/python2.4/site-packages/twisted/internet/tcp.py", line 264,
OpenSSL.SSL.Error: [('SSL routines', 'SSL3_GET_RECORD', 'wrong version
Is it possible to catch it? I put a try...except statement near the reactor
calls, but it didn't work. I was trying to find somewhere else an answer to
my question, however I failed after a couple of hours of searching.
I'm not saying it's a big problem, but it "doesn't look nice" and a good
program shouldn't behave in this way.
