Description Richard Z. 2015-01-14 12:56:19 UTC 
nepomukbaloomigrator has a serious file descriptor leak causing it to crash halfway through the process.

Because some tags will be already migrated users may not notice that the process did not finish successfully and loose data.

Partial strace available.


Reproducible: Always

Steps to Reproduce:
balooctl stop; ulimit -S -n 4096; rm ~/.kde/share/config/nepomukserverrc; nepomukctl start; sleep 600; nepomukbaloomigrator

Comment 1 Vishesh Handa 2015-01-14 14:05:21 UTC 
Hi Richard

Thanks for reporting the bug. Unfortunately, the Nepomuk project is now unmaintained, and the kde4 version of Baloo will not be getting any more updates. I could leave this bug open, but it's unlikely that it will be looked at.

With Plasma5 we're always storing the tags in the xattr, and that makes loosing the tags far more unlikely. Perhaps you want to upgrade and try it out. I'm sure we could use your input.

Thanks again for taking the time to report this.
