Summary: os.environ.update doesn't work
Initial Comment:
os.environ.update doesn't really update os.environ --
it doesn't call putenv subsequently.
This is the test code:
#test1.py
import os
FILENAME='test2.py'
env={};env['ENVIRON_UPDATE']='123';os.environ.update(env)
os.environ['ENVIRON_DIRECT_SETTING']='123'
cmdline='c:\python24\python.exe -u %s'%FILENAME
fs=os.popen3(cmdline,'b')
print fs[1].read()
#test2.py
import os
if os.environ.has_key('ENVIRON_UPDATE'):print
'os.env.update worked'
else:print 'os.env.update failed'
if os.environ.has_key('ENVIRON_DIRECT_SETTING'):print
'os.env assignment worked'
else:print 'os.env assignment failed'
Run test1.py with python 2.4 on windows.
The reason os.environ.update doesn't work is the update
method is removed from 2.4. (It works with 2.3)
