On windows, after mmap.resize fails, self->map_handle
becomes NULL, but it should become INVALID_HANDLE_VALUE otherwise
CHECK_VALID is passed through, it can cause crash like bellow.
import mmap
m = mmap.mmap(-1, 5)
try:
m.resize(-1)
except WindowsError:
pass
m[0] = '1' # crash
The patch is in r69942.

Or, use NULL as invalid handle value for map handle instead of INVALID_HANDLE_VALUE. Maybe this is simpler. |
