NC 20.0.0 - Index name "oc_reader_preferences"."reader_preferences_file_id_index" is too long. #22

Hi,

I was trying to install the 1.4.3 version on the NC 20.0.0 but got the error message of: Index name "oc_reader_preferences"."reader_preferences_file_id_index" is too long.

MySQL server: Server version: 10.5.6-MariaDB-1:10.5.6+maria~focal

Do you have any hints how to fix it?

Cheers, Ferenc

Apparently the maximum length of index names that Nextcloud allows is 27 and reader_preferences_file_id_index has 32 characters.

I wonder how this limit came to be, since the supported database system with the lowest limit (Oracle) still apparently allows 30 characters. The upstream commit message that introduced this limit also don't give an explanation.

Nevertheless, the length used by epubreader certainly is even bigger than 30 characters, so maybe use a name like reader_prefs_file_id_index (just abbreviated the preferences) instead?

Thanks for your report, but this is a duplicate of https://github.com/e-alfred/epubreader/issues/18. Please add any additional information there.
