Failed Conversion from AZW3 to EPUB

[marie44]

Hi all,

I'm hoping someone can look at the conversion error details below and give me some help. This a book I purchased off Amazon and imported into Calibre along with several other Amazon ebook purchases (I strip the DRM on import using the plugin from Apprentice Alf). This was the only one that gave me the conversion error.

I'm not good enough at interpreting the error details to determine if this a problem with conversion or a problem with removing the DRM; if it's a problem with the latter I know I need to direct my question over on Apprentice Alf's blog. However, I suspect it's a conversion issue since I can actually view the ebook in Calibre, which I can't do if the DRM hasn't been removed upon import.

Also, I don't recall changing any of the conversion settings in Calibre but I can't guarantee that I didn't tinker with a setting or two at some point.

Help, please and thank you!

You might want to open a bug on the calibre bug-tracker and attach the file being converted. I saw this in the release notes for 2.21

Conversion: Use a new (written from scratch) implementation of CSS Level 3 selectors that fixes various bugs in handling of the more advanced/uncommon CSS selectors such as nth-last-child()

and it looks as if your issue is related to that.

[marie44]

Bug report submitted. Thanks for the feedback!

I just encountered this in a book of my own.

The pseudo-class :visted is not supported (Error Code: 1)

This is a typo in the css. Somewhere in the css you have something like

.sans_white a:visted {...

That's supposed to be visited.

[eschwartz]

Yes, but the point is, the book shouldn't flat-out fail.

In the editor, this would be caught. Conversions shouldn't care.

[Section8]

Ah - actually, this happened to me in the calibre editor, using the "remove unused css" tool.

[eschwartz]

Hmm, interesting. Are you still on calibre 2.21.0? Because any which way you cut it, this was a regression that is fixed as of 2.22.0 .

[Section8]

I'm running 2.22. It's easy to reproduce - open a random epub in the editor, stick something like "a:vixited {}" in the css, run the "remove unused css" tool, and it fails:

Fix the typo to "visited" and it's fine.

[eschwartz]

I guess this bug isn't fully fixed?

Yep, the first error was in logging. Totally different.

[Section8]

As a test, I tried an epub->azw3 conversion with one of these css typos and the css error was reported in the job log but the conversion was successful.

Ignoring CSS rule with invalid selector: u'a:vxted' (The pseudo-class :vxted is not supported)

It appears that this is different occurrence of the same failure.
