Since this changeset, building on Windows seems to be broken (see http://python.org/dev/buildbot/all/builders/x86%20XP-5%203.x/builds/450 for example). Nadeem

PEP 405 (Python Virtual Environments) and Windows script support
by Vinay Sajip May 29, 2012

May 29, 2012

In the recent check-in I made of the PEP 405 functionality, there is a Windows executable. Antoine asked what this was in his comment on the checkin, but I couldn't respond via Gmane (my usual method) as for some reason his post doesn't appear there. PEP 397 (Python launcher for Windows) has not yet been accepted, so there still needs to be some way of natively launching scripts in Windows which is equivalent to /path/to/venv/bin/foo. The way setuptools (and hence Distribute) does this is to … [View More]

Missing command line documentation for new tools
by Nick Coghlan May 28, 2012

May 28, 2012

The documentation does not currently provide end user guides for pysetup or pyvenv under http://docs.python.org/dev/using/index.html This needs to be fixed before 3.3 is released. I've created the following issues as deferred blockers (since they don't need to be addressed before the alpha this week): pysetup: http://bugs.python.org/issue14940 pyvenv: http://bugs.python.org/issue14939 As the standard library comes to include more directly executed tools, we really need to focus on keeping … [View More]

Proposal for better SSL errors
by Antoine Pitrou May 27, 2012

May 27, 2012

Hello, In http://bugs.python.org/issue14837 I have attached a proof-of-concept patch to improve the exceptions raised by the ssl module when OpenSSL signals an error. The current situation is quite dismal, since you get a sometimes cryptic error message with no viable opportunities for programmatic introspection: >>> ctx = ssl.SSLContext(ssl.PROTOCOL_TLSv1) >>> ctx.verify_mode = ssl.CERT_REQUIRED >>> sock = socket.create_connection(("svn.python.org", 443)) >>&… [View More]

Hacking on the compiler in ways that break the frozen instance of importlib...
by Nick Coghlan May 27, 2012

May 27, 2012

So, I'm currently trying to fix the regression in handling __class__ references in 3.3. The first step in this is unwinding the name change for the closure reference so it goes back to using "__class__" (instead of "@__class__") before finding a different way to fix #12370. As near as I can tell, my efforts are getting killed by the frozen instance of importlib: if I make the change in the straightforward fashion, the frozen copy of FindLoader.load_module() uses zero-argument super(), which … [View More]
