Thinking further, what is the advantage of your code
over iu.py, if this is true? Performance? Do you have
figures?
Paul.
PS I attach a small test script I used to get a feel
for the performance of Jim's patch. Unzip this file,
then do
cd test
zip -0r ../test0 *
zip -9r ../test9 *
Create a copy of the standard library as Lib, and do
cd Lib
zip -0r ../stdlib0 *
zip -9r ../stdlib9 *
Then run test.py.
Figures for me, with CVS + Jim's patch, on a 450MHz
Athlon with 256M RAM running Windows 2000, were:
Lib [[['Lib\\email']]]: 0.309
stdlib0.zip [[['stdlib0.zip\\email']]]: 0.866
stdlib9.zip [[['stdlib9.zip\\email']]]: 1.154
test [[test\testCR.pyc]]: 0.344
test0.zip [[test0.zip\testCR.py]]: 0.204
test9.zip [[test9.zip\testCR.py]]: 0.348
So import from zip is noticeably slower than directory
imports on big zips, but *faster* on small ones.
Compressed zipfiles are slower than uncompressed.
