[Metadata Source Plugin] Kobo Books - Page 6

DNSB · 10-01-2020, 01:11 AM

Not sure if this is a bug in the Kobo Books plugin (1.8.0), calibre version 5.0.1, a Python 3 issue or a thread safe issue with calibre 5.0.1 but I get an erratic error when downloading metadata with this plugin. The lovely part is that it is erratic which is what leans me to the thread safe issue.

Code:

Traceback (most recent call last):

It could be the thread-safe problem. The error in the mechanize library is where it is parsing the URL before sending it. I might not have encoded it properly. Are there any unusual characters in the author or title? And can you post the full log to see what the URL and input looks like.

I've seen a couple of other reports like this. They did seem to be for books being fetched that would need more than basic ASCII. Again, I don't know if it is mishandling the encoding at the plugin end, the thread safe issue, or maybe something missing in mechanize.

DNSB · 10-01-2020, 01:36 PM

I checked the names and there are no special characters in the title or author. Of course, now that I am trying to generate the full log, it worked 10 times running.

I'll leave it until Kovid Goyal has done his rewrite of the zipimport module to make it thread safe.

Good afternoon, this plugin has suddenly stopped fetching metadata from Kobo for me, even as I can confirm that the book is in the Kobo web shop (I have even attempted to fetch metadata for books I had successfully matched previously, just to troubleshoot).

I have attached the log below. I have attempted to delete and reinstall the plugin, but the issue persists. I am using Calibre 5.13 on OSX 10.14.6. The only other interesting thing about my log is that Amazon has also suddenly disappeared from the metadata search, which makes me wonder if the issue is truly with Calibre.

Spoiler:

Thank you for any insight or assistance you can provide!

Shpounz · 03-14-2021, 05:11 PM

I have the same issue on my side since yesterday

DNSB · 03-14-2021, 07:04 PM

For what it's worth, I tested several books that worked with Kobo previously and no results today. I reverted back to calibre 5.11 and 5.12 and no results with either of those.

Spoiler:

Probably a change on the page. I'll have a look as soon as I can.

Thank you so much. I look forward to seeing what you figure out.

Ah, whew! I thought it might have been just me - no covers grabbed from Kobo books in the last week or more despite knowing the book is there

davidfor · 03-20-2021, 01:41 AM

I have just released version 1.8.1 of the plugin. This is to fix the problems dues to recent changes to the site.

The change in this release is:

Fix: Change in tags around the title on both the details and search results pages.

Calibre will announce the update in the next hour or so. If there are any issues, please report them here.

Thanks for this update
It seems to work on my PC but not on my mac where I get the following error :

In fact, it doesn't work on my PC either.

The error is as follows:

Sorry, I left in a debugging statement that would only work on a Windows machine that has a writeable E drive. The worst thing is that I didn't even use it.

I have just uploaded the fix. That will be announced by calibre in the next hour or so.

It seems to work now. Thanks for the responsiveness

Poetry abandoned rhyme and meter; music ceased to be tonally centered; and painting no longer aimed at faithful representation. These artistic developments have been attributed to cultural factors ranging from the Industrial Revolution and the technical innovation of photography to Freudian psychoanalysis. In this book, Samuel Jay Keyser argues that the stylistic innovations of Western modernism reflect not a cultural shift but a cognitive one. Behind modernism is the same cognitive phenomenon that led to the scientific revolution of the seventeenth century: the brain coming up against its natural limitations. Keyser argues that the transformation in poetry, music, and painting (the so-called sister arts) is the result of the abandonment of a natural aesthetic based on a set of rules shared between artist and audience, and that this is virtually the same cognitive shift that occurred when scientists abandoned the mechanical philosophy of the Galilean revolution. The cultural explanations for Modernism may still be relevant, but they are epiphenomenal rather than causal. Artists felt that traditional forms of art had been exhausted, and they began to resort to private formats—Easter eggs with hidden and often inaccessible meaning. Keyser proposes that when artists discarded their natural rule-governed aesthetic, it marked a cognitive shift; general intelligence took over from hardwired proclivity. Artists used a different part of the brain to create, and audiences were forced to play catch up.
