Running import/export channel operations within a task for import/export content operations does not properly manage the overall progress #5501

Open indirectlylit opened 5 years ago

indirectlylit commented 5 years ago

Observed behavior

when exporting content to disk, progress hangs on 100%, resets to 0, and then starts over

Expected behavior

The entire process of exporting should be represented by a single pass of 0-100%, because the user is not aware of sub-stages

User-facing consequences

confusion & possible annoyance. Risk of hitting 'cancel' and losing progress

Steps to reproduce

select content to export to disk
begin process
watch bar get to 100%, hang there, start over, and then reach 100% again

Context

0.12.3

@radinamatic this one is still extant in 0.15.1 although in a slightly different way - once I hit the Export button I see the progress bar reaching 84% then goes to 9% and then proceeds to 100%:

I am guessing this is probably due to a mismatch between progress reporting of the component jobs (exportchannel and exportcontent) that make up the overall flow here.
