Calibre content server

rashuf · 01-19-2018, 09:20 AM

Hi!
I built Calibre with utf8 support - I added option "Do not use translit when adding book" on Preferences\Adding book. This option is important for me. I read this thread https://www.mobileread.com/forums/sh....php?p=3297688. I added russian (I'm from Russia) translation and correct the content server translations.
All work fine, but i don't add the same option for content server. I modified content.py\book_filename. Now I click download button, I get 404 error. Why??

What can read about content server?
PS: Are you interest utf8 support for files in calibre library?

No filenames in the calibre library will always be ascii only, for widest compatibility. Similarly the content server uses ascii encoding for the content-disposition header, because there is a lot of http middleware that mangles non-ascii headers.

Hi, Kovid!
Yes, I know that ascii-translit is for widest compatibility. But added option (do not use translit) is one of more options - by default, is disabled.

I want add path/filename template preferences for added books - it looks like metadata reading preferences. These features make calibre is catalog program. Processed (added to calibre) books will be easy to find without calibre. This is bad?

I also met that users want this feature for great program Calibre.

Yes, it is bad, because it can lead to data loss and it means that I have to provide support for people using that option that run into problems.

Actually, with the content server it may be possible to use RFC 6266 (which is not yet a standard but widely supported) to have non-ascii filenames in the content-disposition header. It would need testing on a wide variety of browsers/devices to ensure it does not break things.

It's clear.. But strange, because utf8 - it's standard de-facto. I tested on Windows - all is work..
Ok! But I don't understand how book filename from temp folder (for example "C:\Users\ROR\AppData\Local\Temp\calibre_xgziak\sr v-deaebc\fcache\f\fmt-Calibre_Library-f.fb2") is transformed in "Gierbiert. Diuna. Piervaia triloghiia - Frenk Gierbiert_15.fb2". Please, help me understand this. I don't know python or js. I tried to debug through VS and Firefox, but understood nothing.
...
YES! Thank you!!

I will try this.

Thank you, Kovid, again! It works fine!
PS: i forgot about utf8 urls

For example, https://ru.wikipedia.org/wiki/Calibr...BC%D0%BC%D0%B0) - ru.wikipedia.org/wiki/Calibre_(программа)
