Hi,
I am trying to migrate from Python 2.5 to Python 2.7 I found though the mmap
behaves differently on Windows XP between the two versions. It boils down to
the following code:
import mmap
map1 = mmap.mmap(fileno=0, tagname='MyData', length=4096)
map2 = mmap.mmap(fileno=0, tagname='MyData', length=8192)
It runs fine (so I can "resize" shared memory) on XP with 2.5.4, but when
running on 2.7.2 I get the following error
Traceback (most recent call last):
File "D:\Workspace\memmap_test.py", line 3, in <module>
map2 = mmap.mmap(fileno=0, tagname='MyData', length=8192)
WindowsError: [Error 5] Access is denied
