Calibre 0.8.5 - my plugin quit working

[DiapDealer]

I have a plugin that imports pycrypto (included with Windows calibre) from the calibre2 lib (site-lib?) directory. It just uses the simple:

from Crypto.Cipher import AES as _AES
from Crypto.PublicKey import RSA as _RSA

The plugin worked fine with calibre 0.8.4, but doesn't work with 0.8.5. Is there anything I special I need to do to import from the pylib.zip zipfile—where all the libraries seem to have moved in 0.8.5—from within a plugin? Do I need to append something to the sys.path? Or is there something wrong with the pycrypto compiled libs included with calibre 0.8.5 (windows)?

Thanks.

It looks like it may have something to do with the Crypto folder's (in the Windows Calibre distro) move from pydlib to pylib.zip in 0.8.5. Will those libraries be available for import in a plugin if pylib.zip is included in sys.path (as seems to be the case)?

It should just import. Run

calibre-debug -c "from Crypto.Cipher import AES as _AES"

to see what the error is.

Ah, apparently pycrypto requires distutils, I'll upload a fixed build in a bit.

[DiapDealer]

No hurry. Thanks for looking into it.
I could include my own stripped down version of pycrypto libs (and any dependencies) in the plugin pretty easily, but it seemed like overkill since it was already included as part of calibre's Windows binary install.

Thanks again!

I've uploaded a fixed build. At least your two import statements work, I haven't tested it beyond that.

[DiapDealer]

That did it. I thank you sir!

Hi,

Any chance this issue still exists in the calibre-portable version?

Thanks,

[kovidgoyal]

No, both were rebuilt. You can check that there should be no AES.pyo file in pylib.zip
