Hi:

Display files are written in a background job, because otherwise saving a file would block the complete UI.
When closing the application, we don't check if there are still running background jobs, and simply quit.
That's bad for display files. On the other hand, jobs that simply fetch data for a display might be aborted, since you obviously don't care any more when you exit the tool.
So needs a little more work to fix it, but I'll look at it.

Thanks,

Subject: [EXTERNAL] Corrupted bob files CSS

Hi, 

When saving files in CSS Phoebus I see that they get corrupted if I close CS Studio before the save completes. The bottom ~half of the text file gets deleted.

I have done this on a number of occasions when I realised that I was trying to save in the wrong location, or saving over a slow connection to a remote server. I had pressed the “cancel save” button in the jobs list, which then told me
 that the save had stopped before I closed the application. 

Is this a bug or just something we need to work around? It’s never a huge problem because we can just revert to a previous commit but it would be nice if saving didn’t corrupt files even if it didn’t complete.

Thanks, 

Will
