On qgis master (1.9-93ade1f) The delete selected features on table view doesn't work. Nothing happens when push it.

Not confirmed here ..
Can you describe what you did and with what data you were working?

I also do not confirm, on Linux.

But I notice a huge regression in the time it takes to delete records.

In a quick test, I arrived at these results, deleting 600 records from a points layer:

• QGIS 1.8: almost instantaneous;
• QGIS Master: ~77s. It looks like delete one by one.

Anyone confirms?

I also do not confirm the first problem (it could be a my local PC problem), but I confirm the regression in deleting records.

I think that in the very latest master code there was an improvement, but still slower than 1.8

I just try with master compiled today and the same 600 records that yesterday took 77s, today disappear instantly!

Matthias committed big changes in this compartment, expected improvement also for table selections, to be tested.

Can we close this?

Yeah, I'm noticing quite a few improvements in the performance of interaction with the attribute table.

Yes, I think we can close this ticket.

Thanks!
