Potential bug?

Hi all,

I tried to replace a database in the BaseX Database Administration (dba). A simple task that I often do. But this time, I get this message:

Unexpected error: Improper use? Potential bug? Your feedback is welcome: Contact:basex-talk at mailman.uni-konstanz.de Version: BaseX 9.2.1 Java: Oracle Corporation, 1.8.0_231 OS: Linux, amd64 Stack Trace:

Hi Philippe,

I remember we’ve fixed a bug like this 2, 3 years ago. BaseX 9.2.1 is pretty old now; do you have a chance to upgrade to BaseX 10.4 or at least BaseX 9.6.4?

I guess the problem should disappear if you run OPTIMIZE ALL or db:optimize(..., true()) and switch to the new version.

Hope this helps, cordiales salutations, Christian

Hi Christian,

Thank you very much. The function helped me to find the solution to my problem, and to solve it

Now I'll look into upgrading to the new version.

Best regards, Philippe

Basex: has so few bugs that Christian remembers every single one ;)
