Calibre Won't Convert This Book

[enuddleyarbl]

Calibre doesn't seem to want to convert Jay Kristoff's "Nevernight" from AZW3 to epub3:

https://www.amazon.com/Nevernight-Ch...ef_=ast_sto_dp

I downloaded a fresh copy of the AZW3 from my library of books on Amazon, Added it to my working library in Calibre, right-clicked on it and told it to Convert Individually. Normally, a conversion like that takes only a handful of seconds. I've let it run for over two minutes (with it using over 10% of my CPU) and it doesn't complete (according to the Jobs area in Calibre, it doesn't get beyond 1% complete). I've tried multiple times with restarts of everything up to the computer, itself. No dice. It's 100% reproducible on my system.

I then used the KindleUnpack plugin to do a KF8 to Epub... and that worked fine. I could edit the resulting epub to my heart's content without issue.

If anyone has access to that book, could you try doing a conversion to epub3 on your system?

Also, I used the ScrambleEbook plugin to obfuscate the AZW3, added that into my working Calibre library, tried to convert that to epub3 and had the same problem. Here's a link to that obfuscated book so you can try converting that if you want:

https://drive.google.com/file/d/1OHk...ew?usp=sharing

The last time I tried converting the AZW3 to epub3, I stopped the process after two minutes and grabbed a copy of the log from Show Job Details under the Jobs area. Here's what it showed:

Big list of invalid ID, won't stop it converting or working

TOC seems OK

Converts fine for me (quickly) to epub2 even with those faults in the CSS
Calibre 6.10, Linux Mint 20.1, Mate Desktop, custom theme.

So I tested epub3, which took a little longer and also OK.

Unless your original images has a broken one?

Can you view the azw3?


My default settings include
Use Tablet for Images
remove the CSS with line-height or white-space
I'd fix those "errors" anyway. The font ones are silly and while the ID thing doesn't seem to matter it can be fixed with one click.

[Quoth]

Turn off Heuristics on conversion. I never use it and it can cause issues.

I'd only automatically remove paragraph spacing and set justified on gutenburg ebooks, occasionally I have to edit CSS of a book from Amazon but only obvious when I start to read.

[enuddleyarbl]

Yes. I can edit the original AZW3 without issue and see the same things you're seeing with Tools > Check Book. OTOH, EpubCheck has fatal issues with the book. Running that gives an error dialog with the following details:

Both of those logs in my first two posts end at the same point (even though I let one run go for over two minutes and the other only a few seconds):

I don't really know how to read that, but if it means it was in text/part0035.html when it got stuck, there are non-breaking spaces in that file. In the original AZW3, those are

& # x 0 0 A 0 ; (I had to modify that string since even code blocks replaced it

codes. In the file I got from KindleUnpack, there are no codes there at all (just yellow blocks of space. Ditto for what's there if I run the AZW3 through Calibre's Polish Books function (which works fine, though it takes more time than I'd expect). I see references to

& n b s p ;

and

& # 1 6 0 ;

as being the usual way of creating non-breaking spaces. Could Calibre be having issues with

& # x 0 0 A 0 ;

?

I see this on The Quiet Gentleman, azw3, 99p today. with EpubCheck

But it and your example convert fine.

Confirm you don't have Heuristics enabled!

After conversion the regular check found a few stupid vertical-align and numeric prefix IDs.

Epubcheck completed and found more stuff not needed, like parameters in body or section, but no fatals

@enuddleyarbl try in safe mode. Something you have running is causing your conversion problem. I converted the scrambled version in 2 seconds. With heuristics on and remove paragraph space on, it takes 3 seconds.

So I would say it's something with your computer. What AV do you use? I use the one that comes with Windows 11.

[Quoth]

Yes, it's something enuddleyarbl has though I never use Heuristics.

But it's the first time I used EpubCheck on an azw3, generally I'd only run it on real epubs.

And I agree, the MS free AV is less bother than bought ones. They cause more damage than protection if you have other measures and use Windows properly.

[Quoth]

as being the usual way of creating non-breaking spaces. Could Calibre be having issues with
Code:

& # x 0 0 A 0 ;

I doubt it.

[enuddleyarbl]

Since the two of you aren't having the same issue, I guess I'll chalk this up as another incompatibility with my AMD graphics card. I'd dropped back from the latest driver to the previous "Recommended" version of 7 months ago because of issues with Calibre and its Editor not running at all sometime. With the old drivers, that problem went away. This problem (which I'd never seen before) is similar in that the Calibre process will grab a bit over 10% of the CPU while nothing appears to be happening. Bummer.

But, thanks to both of you for trying the conversion.

EDIT: Sorry, it turns out I converted the wrong book in Safe Mode. When I figured it out, went back and tried converting the proper book in Safe Mode, IT DID NOT WORK. Yay? Anyway, that seem to rule out something running on my system. But, why this book would convert properly on other people's systems is beyond me. I assume you guys aren't using AMD equipment.

OP: I booted into Safe Mode and the file converted in 3 seconds without issue. I'm guessing AMD will be sending out another graphics drivers in a couple of days. When I try that one, I'll first try removing the old software and running with whatever Windows defaults to. I expect the problem to go away there, too (as it did with that other problem I mentioned).

It's just odd that it's 100% reproducible with this file and doesn't happen with any other (that I've run into... yet). I'd think that would imply some structural issue with the AZW3 causing the problem.

[enuddleyarbl]

I edited my prior post because I'm an idiot.

[kovidgoyal]

Turn off heuristic processing, it can cause issues which is why it is off by default.
