upgrade to os x 10.9 seems to introduce tracd errors

[Bill Hernandez (Plano, Texas)]

I have installed OS X 10.9 Mavericks on several machines, and after reboot I notice errors that I have not seen with prior versions of the operating system.

$ tracd --version
tracd 1.0.1

Any ideas ?

I was not able to find any info on how to remove "build/bdist.macosx-10.8-intel" and install "build/bdist.macosx-10.9-intel"

I am not a python person, so I would be most grateful for some detailed info…

• It seems that it depends on browser. Are you using what of browser?
• Also, I think it's a SocketServer.py issue. refs ​SO:6063416 and ​http://bugs.python.org/issue14574.

I have an applescript that sets up a number of things, launches the terminal, launches Safari and pulls up my master page.

I changed all the references to Safari with "Google Chrome", restarted the machine and there was no change in the errors.

Hopefully someone will have a fix.

Thank You!

Reproduced on Python 2.6 and 2.7 on Linux with Firefox and Chrome on Windows. Not reproduced on Python 2.5. When the client disconnects, the issue occurs. #8357 is related.

Try the following patch.
