My bad.
Here's one sfw link I tested:

Are you in the correct thread? None of those errors are from FFF.

Additionally, the messages about invalid escape sequences is a warning to the developer and not affecting you.

My apologies.

[DragoLord19d]

Ah. Well I was getting it whenever I used FFF so I figured I should ask you first

Maybe something smaller next time if possible? That story contains 452 chapters and 3388 images.

I launched a download of it using CLI (my usual initial test platform) and left. +40minutes later it finished without any problems. For completeness sake, I tried a few chapters in Calibre.

To my surprise, images did fail there. It's pretty uncommon for CLI and plugin to differ like that.

Looking in the log and epub, it reports Invalid URL 'https:////10539.mitemin.net/userpageimage/viewimagebig/icode/i110766/': No host supplied. With //// instead of //.

Looking at the source site, the images are given as <img src="//10539.mitemin.net/userpageimage/viewimagebig/icode/i110766/"

FFF has code to handle such cases and prepend the appropriate scheme (https usually). But python's built-in urlunparse is behaving differently in plugin vs cli? That sounds like python version shenanigans. And Calibre 9.9 is running Python 3.14.5 while I still have 3.12.0.


And sure enough, the python gods apparently changed urlunparse() in 2024.

It's only showing up now because it's not an issue for us except when the url starts with '//', and, I assume, Calibre didn't update python immediately.


I believe I see how to fix this. I made assumptions about how urlunparse() works when given a 'location' that also includes then 'netloc'(aka domain name).

But I need to look at everywhere FFF uses urlunparse() and do some testing.

DragoLord19d - no problem.

Although I wonder why your posts are requiring moderation...

This touches more code than I'm really comfortable with. So keep an eye open. Documented in issue #1377.

Changes touch:

• adapter_storiesonlinenet login
• fix_relative_text_links (on by default)
• Redirects using BrowserCache
• Relative/incomplete links in HTML for Get Story Urls from Page, email, or drag and drop
• Relative/incomplete links for image urls

FanFicFare stopped working for me. I'm on Calibre 9.9, FanFicFare 4.58.0

Getting a list index out of range on any series on Literotica.

Tried it with multiple series. Full log below. The URL used is SFW.

I just noticed an issue with getting stuff from literotica. FFF only downloads the first page of any story, be it a stand alone or one in a series. I'm using the latest beta.

I noticed the same thing when I updated to the latest Calibre version (9.10) -- no issues with the 9.9 version with recent FFF test version (4.58.11)
