Is this a Bug on DMSF or my Fault? How can fix it?

[picman]

It seems that some of your folders have got invalid characters in their names. Try the following command and fix any wrong titles.

select id, title from dmsf_folders where title REGEXP '[]:<>#%*[[<>%?"\/]';

[Hofei90]

Hello,
this i get when i execute the command:
select id, title from dmsf_folders where title REGEXP '[]:<>#%*[[<>%?"\/]';

MariaDB [redmine]> select id, title from dmsf_folders where title REGEXP '[]:<>#%*[[<>%?"/]';
Empty set (0.00 sec)

Add 1st error)
I've fixed a bug in DB migration. If you pull the master branch, the migration should be Okay now. Or, you can apply the same change as in dda3ae4 manually.

Add the other errors)
I'm afraid that you will have to fixed it manually before the next migration. Eg.:

Mysql2::Error: Duplicate column name 'system': ALTER TABLE dmsf_folders ADD system tinyint(1) DEFAULT FALSE NOT NULL

=>

ALTER TABLE dmsf_folders drop column system;

[Hofei90]

Ok, i download the master branch and execute the command:
ALTER TABLE dmsf_folders drop column system;

now i get this error message after bundle exec rake redmine:plugins:migrate NAME=redmine_dmsf RAILS_ENV="production" --trace :

Tasks: TOP => redmine:plugins:migrate

Unfortunately, I can't help myself in ruby at all. I haven't really figured out the system yet.

[picman]

One more improvement. Please git pull and try it again.

[Hofei90]

Thank you - now it works.

However, I still have a problem.
But this will probably be better dealt with in a new issue?!
But this has more to do with the fact that I changed the storage path.

Old version:
/opt/redmine/files/dmsf
New Version:
/opt/redmine/redmine-4.0.2/files/dmsf
Now I get displayed on the web interface when I select a file in DMS:
404 - The requested page does not exist or has been removed. Also, when migrating, the corresponding messages appear.

In the administration interface I have entered the new absolute path, how do I manage to find the files again?

[picman]

The migration should have reorganized files. They used to be organized by the project identifiers dmsf/p_my_project/, but now they are organized by creation date dmsf/2019/03/. If the migration failed to move files to the new location from whatever reason, you must move them manually.

Please see #799 and #767 for a solution.

[Hofei90]

Okay, I'll look at the two issues shown.
If I don't get it right, I'll get back to you ;)

Many thanks for your quick help and at this point also a big thank you and a big praise for the really practical and well working DMSF plugin which is provided for free as Open Source Software - thank you!
