Re: [Python-Dev] Python 2.5 performance
Well, it ought to be possible. I can turn off the instrumentation on the other modules, and see what happens.

Re: [Python-Dev] Python 2.5 performance
I must confess that I am not familiar with the buildbots. I could imagine that it would be difficult to set up internally due to security concerns, but I can voice the issue here.

Re: [Python-Dev] Promoting PCbuild8 (Was: Python 2.5 performance)
Kristján V. Jónsson schrieb: > I must confess that I am not familiar with the buildbots. The challenge and work-load is primarily initially in setting it up; in this case (for PCbuild8), there is work for both the master and the slave sides (probably, new scripts in Tools/buildbot will have to be created). > I could > imagine that it would be difficult to set up internally due to > security concerns, but I can voice the issue here. It's not mandatory, of course: neither that there is a PCbuild8 buildbot at all, or that it is hosted at ccpgames. It just would reduce the chance that breakage of PCbuild8 goes unnoticed for long. As for the security concerns: the buildbot slave actively opens a networking connection to the master; you don't have to open any additional ports on your firewalls. Of course, the master can send the slave arbitrary commands to execute, so if the master is taken over by some attacker, that attacker could easily get control over all slaves also (except that you want to run the slave in a restricted account, so that the attacker would have to find a hole in the slave's operating system, also, before taking the machine over completely). As for making VS 2005 "more official": you also might have meant that the PCbuild directory should be converted to VS 2005. That would have a number of implications (on the buildbots, on changes to Tools/msi, and on potential usage of VS 2007 for Python 2.6), which need to be discussed when somebody actually proposes such a change.

I'll look at what I get back for libs and update my build script. All my code is C++ and in the past distutils lacked C++ support so I could not use it and have develoer my own solution to the build problem. Does distutils work for C++ code these days?
