Opening field calculator eats up all CPU

Original Redmine Issue: 13075
Affected QGIS version: 2.10.0
Redmine category:field_calculator

---

Opening the field calc, either from the main toolbar or from the table view, takes almosta a minute here, even for samll layers, and CPU jumps close to 100%, thus making the whole system quite slow until one closes QGIS.
It's a regression over 2.8

not reproducable on master - steps to not reproduce open airports.shp from qgis sample dataset and click on "open field calculator" in "attributes" toolbar.

---

• status_id was changed from Open to Feedback

It seems independent from the specific shp. Just tested on a clean --configpath, no plugins, with the supersimple attached shp.

Can't confirm here too. Nothing in the debug log?

Nothing. Anything else I can do to debug it?

not reproducable on 2.10 and master (both Linux and Windows). Lowering priority as it is likely a local issue.

• priority_id was changed from High to Normal

Tested on another machine, it works, so it must be a local issue. It is pretty dangerous however, so it would be good to debug it. I'm available for it, if someone can provide me what to look at.

reopen if replicable in any way also on systems other than yours.
