[QGIS-Developer] Cancelling a running processing model

[Andreas Neumann]

Hi, 

I am working with processing models these days - and depending on the
data amounts, the algorithms run quite long. 

I noticed that although there is a "Cancel" button, this button has no
effect during the execution of one single algorithm that takes a long
time. Only after the execution of this single algorithm, then the
subsequent algorithms are cancelled. So if, e.g. a buffer algorithm
takes 5 minutes to execute and it is just one part of the whole model,
then if the user presses cancel during the execution of this buffer
algorithm, then he has to wait until the buffer algorithm finishes. Is
this observation correct? 

Note that I am using 3.10, not 3.14 or the latest master - maybe
something has improved in this respect in later versions? 

If nothing was improved in this respect - is there a chance to improve
the situation in the future? 

Thanks for the discussion, 

Andreas
