Summary: python 2.2 shelve

Initial Comment:
I've created a shelve 'db-test' under Red Hat Linux 7.1
and Python 2.1.1. When I want to open this shelve under
Win2k with Python 2.1.1 or Python 2.2, following occurs.


>>> db = shelve.open("C:\db-test")
Traceback (most recent call last):
  File "<pyshell#4>", line 1, in ?
    db = shelve.open("C:\db-test")
  File "C:\PROGRAMS\PYTHON22\lib\shelve.py", line 158,
in open
    return DbfilenameShelf(filename, flag)
  File "C:\PROGRAMS\PYTHON22\lib\shelve.py", line 148,
in __init__
    Shelf.__init__(self, anydbm.open(filename, flag))
  File "C:\PROGRAMS\PYTHON22\lib\anydbm.py", line 86,
in open
    return mod.open(file, flag, mode)
  File "C:\PROGRAMS\PYTHON22\lib\dbhash.py", line 16,
in open
    return bsddb.hashopen(file, flag, mode)
error: (22, 'Invalid argument')


Is there a bug in the bsddb.lib und Windows? Is there a
solution to create shelves under Linux and to use them
under Windows?

Thanks

Unfortunately, there are different versions of BSDDB in
circulation, which use different file formats.

On Linux, please do

ldd <path-to-python-lib>/lib-dynload/bsddbmodule.so

to find out what version you have linked with. Also, please
invoke file(1) to find out the file version. I can't tell
off-hand what version the standard Windows installation is
build with, but knowing what you use on Linux will get us
closer.
