import dll instead of pyd

[jrh]

Hello,

From previous posts and documentation it seems python should be able
to import a module that is compiled into a .dll just as well as
a .pyd. I have a pyd that works fine, but after renaming it to dll the
import fails. Running python with -vv flag indicates it doesn't
actually look for the dll (see below). Has dll import been defeatured
in python?

Thanks!

Yes it is in the same directory. The problem is it does not seem to
look for dll's at all. So is this by design, or am I missing
something?

looks like that was removed in 2.5; from Misc/
- On Windows, .DLL is not an accepted file name extension for
extension modules anymore; extensions are only found if they
end in .PYD.

which is easily confirmed:

Python 2.4.3[('.pyd', 'rb', 3), ('.dll', 'rb', 3), ('.py', 'U', 1),
('.pyw', 'U', 1), ('.pyc', 'rb', 2)]

Python 2.5[('.pyd', 'rb', 3), ('.py', 'U', 1), ('.pyw', 'U', 1),
('.pyc', 'rb', 2)]

(the DLL support was a compatibility thing anyway, so I guess removing
it after 10+ years is a reasonable thing to do...)
