How do you trigger this error in QGIS? I've been unable to reproduce.

#2 Updated by Arjan Mossel over 6 years ago

  • Status changed from Feedback to Open

I installed QGIS 2.99 (alongside 2.18) via osgeo4w-setup-x86_64.exe, on Windows 7. Currently at b6ad920404 (updated yesterday).

I can reproduce it by doing "New SpatiaLite layer", creating a new database with a table with just a text field. Then opening this database in the Database Manager and doing "Run Vacuum" results in a popup with "cannot VACUUM from within a transaction".
