QGIS 3.2 processing scripts not updated when saved / crash when trying processing options > ok

Crashes QGIS or corrupts data:Yes Copied to github as #:27757


When editing processing scripts in QGIS 3 with right click > Edit script... in the processing toolbox, save it and then try to execute it by double clicking it in the processing toolbox, the script version that was loaded at QGIS start is executed, not the one just edited. The only (painful!) way to execute my edited script is to restart QGIS 3 any time an edit is made.

Deleting the pycache folder under ...processing/scripts/ seem to have no effect.

Sometimes opening the processing options and pressing OK has the desired effect (cp. answer to [[https://gis.stackexchange.com/questions/296665/update-processing-scripts-in-qgis-3]]), but in most cases when trying this QGIS crashes. Report below.

[processing] Reload scripts after a script has been saved in the editor

Fixes #19934


#1 Updated by Nyall Dawson about 2 years ago

I suspect the crash reported here has already been fixed -- it was likely a crash caused by having a processing algorithm dialog open when the options window was opened.

But the issue regarding the scripts not updating remains.
