Re: [Pythonmac-SIG] Python virtual environments on OS X
Ronald Oussoren ronaldoussoren at mac.com writes: The 'env.cfg' file will be next to the stub executable, and hence not in a location where the real interpreter will look. 2. How does the stub locate the real executable? The stub is linked to the framework and uses that to find the sys.prefix, the real executable is located in a fixed location relative to sys.prefix. That's one other difference w.r.t. regular builds: framework builds use the location of the shared library to calculate sys.prefix. AFAIK this functionality was inherited from the NextStep port. Here's the approach I've taken to this - please comment. 1. I modified the stub loader to set an environment variable __PYTHONV_LAUNCHER__ to the absolute path of the stub executable itself. The environment key seems unambiguous enough and shouldn't clash with anything else. This might seem clunky, but seems the most obvious way to feed this information to the real executable. 2. The stub is copied to an environment's bin folder (but nothing else is, for the moment, though I've written the code to copy the dylib, Info.plist, real executable etc it's currently commented out). 3. When the stub is run, it finds the framework executable in the usual way, and runs it. 4. When the real executable gets control, code in site.py picks up the environment variable's value and looks for the env.cfg relative to that location. AFAICT this should be enough, since the real executable is executed from its framework location and presumably has access to all tbe necessary context for GUI applications, etc. I've verified that sys.site_prefix, sys.site_exec_prefix and sys.path correctly point to the virtual environment. I ran the full regression test suite in a virtual env, and only got failures in test_lib2to3 and test_packaging (due to known issues with those tests writing into write-protected locations - this happens with vanilla installed Python 3.3, too). PyObjC supports Python 3, the site is very much out of date. I haven't found time to redesign the site yet, which needs to be done because the maintanence scripts no longer work due to some code reorganisations in PyObjC itself. Are there instructions somewhere on how to build and integrate into a framework build's Extras?

[Pythonmac-SIG] py2app under Lion--any issues?
Will py2app to work to build Mac application bundles under Lion (MacOS X 10.7)? I'm using python.org 32-bit python and ActiveState Tcl/Tk 8.4.19 and trying to build self-contained Python/Tk apps that run on at least MacOS X 10.5 and later. I assume there's no problems, but it would be very helpful to know what to watch out for if there are. -- Russell ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig unsubscribe: http://mail.python.org/mailman/options/Pythonmac-SIG
