[GUI Plugin] Quality Check

[zzjing]

Hi kiwidude,

I know this is an odd request, but since it seems that Amazon is removing sideloaded books marked as EBOK, I'm trying to find a quick way to mark all my sideloaded books as PDOC instead. Is it possible to add another item to the fix menu to do just that? It should be just like "Fix ASIN for Kindle Fire" but instead of setting cdetype to EBOK, you set it to PDOC. It would be a godsend. I am trying to change them one by one with MobiMetaEditor and it's taking forever.

Thanks for the great work.

I decided to try to look at the code and see if I can hack it. In the process, I think I have found a bug in "Check missing EBOK cdetype". It seems that exth.cdetype is a byte string, so in check_mobi.py:

if exth.cdetype == 'EBOK':

always fails, and should be changed to

if exth.cdetype == b'EBOK':

Hope this helps.

I think that was a bug and they've stopped/fixed it?

Are you referring to the problem of sideloaded books disappearing on Kindle? It just happened to me for a second time. That's how I found my way here.

Where did it say it was fixed?

Thanks for that, I can apply that fix. However I admit I know zero about MOBI format (this feature was added by someone else to the plugin). From looking at the code the existing "Fix ASIN for Kindle Fire" code actually sets the EBOK value to the asin for the book. So I am confused as to what you would try to do by adding another "Fix" feature to this plugin - what else is it going to set the EBOK value to?

In other words - if I push a new version of the plugin that corrects the bug allowing you to identify MOBI files that have no EBOK header set, is there any reason why you would not just then use the existing "Fix ASIN" feature to then change the books?

There is an ongoing issue with Kindles and Amazon removing books. It seems that if the ebook CDEType is set to EBOK, the ASIN belongs to an existing Amazon ebook and your Kindle has not synced with Amazon for quite a while, Amazon's end decides that the book should not be on your Kindle and deletes it. One suggested fix is to set the ebook CDEType to PDOC.

In addition to fixing the ASIN, the existing "Fix ASIN" feature sets the cdetype to EBOK in the MOBI header. The problem is that sideloaded books marked as EBOK started to get deleted after the kindle device gets off Wifi for an extended period of time. This happened to me twice, and there is a long thread about it. So I'm trying to set the cdetype to something other than EBOK to prevent my sideloaded books from being deleted by amazon.

Fortunately the code is pretty straightforward and it's an easy hack. So now I can change it to whatever I want with a local copy of the plugin.
