Sanitize file name when recording from EPG

[Vlado99]

Hello.

Usually, I schedule recording from the "TV Guide" page. If the program name contains ellipsis "...", e.g. "Nesnesitelná lehkost bytí, Unbearable Lightness of Being, The, Velikáni filmu... Juliette Binocheová", the recording fails. Inside devide-adapter0.log I found this:

2026-02-08 22:10:00:101 [ERROR] Parent directory (..) path names not supported

Can You Improve the program name string sanitization before it is used as file name, please?

In the next version there is an improvement in the filenaming logic but this use case might need further review.  It would help to get a full mux to see why the title and description are not split better.

There are several aspects related to this error:
- The user doesn't get information that something is wrong when he/she requests recording. He/she does't know he/she should take action to fix situation.
- File name/directory name of pending recordings are not editable. User must delete recording from Scheduler and place the Manual recording, which is much more difficult to set-up than from Guide page. Choosing Recording Name in Manual Recording he/she influence file name.
- The part of program which protects from escaping recordings from configured directory is poorly written. Insted of splitting path to components and compare each component if equal to "..", it searches the whole string.

I hope this problem will be solved soon. (In the meantime I lost another recording :-(. )

The next version is awaiting final package by the author sub, but without the requested full mux it is hard to ensure that the issue is resolved. If that fullmux is impossible to provide perhaps you can send a link to your database and I can look at other example.

The current logic for processing the ellipsis is based on the end of the title and the beginning of the description which is working for the UK data it was designed for. However in this case I don't think that is the issue. I have tried recreating the issue but on my Linux system the following are possible

Code:

mkdir "Nesnesitelná lehkost bytí, Unbearable Lightness of Being, The, Velikáni filmu... Juliette Binocheová (1988)"
touch "Nesnesitelná lehkost bytí, Unbearable Lightness of Being, The, Velikáni filmu... Juliette Binocheová (1988)/Nesnesitelná lehkost bytí, Unbearable Lightness of Being, The, Velikáni filmu Juliette Binocheová (1988).ts"

so the ellipsis doesn't necessarily need to be escaped

However I can't actually duplicate that here because of this

Code:

so I don't see the ellipsis anyway and I am not sure why since you didn't post complete logs.

However when I fake them earlier ellipsis strings are removed completely in 7.0.5 so the change may work for you.

In the meantime, I had a successful recording with "..." too, but yesterday: nextpvr-logs.zip

[mvallevand]

Right it works when the .. is later in the filename since the filename gets truncated. Wait for 7.0.5

The 7.0.5.260307 works well so far. Thank you very much!
