Re: [Fractint] Fractint version 20.4 patch 7
Jonathan, I had something weird happen. I was generating a 1600x1200 image (Disk video mode, passes=1) in a Windows XP batch file, and doing an automatic save every 10 minutes. After about 40 minutes, I noticed that it did the fourth automatic save after line #1195. A few seconds later, when it finished, the file was completely gone! (I've never seen this happen in DOS.) I suspect it has something to do with the timing and buffering in Windows - the deleting of the old file after line 1195 not being executed by Windows until after the file was saved again at the end of the fractal's generation a few seconds later. But occasionally, when running a batch job, I've noticed that one of the images was missing, and I had to regenerate that image again. This could have resulted from similar behavior when an automatic save was done just before the image would normally complete. Lee

Windows doesn't do this. You ask to delete a file and its deleted by the time the function returns. It doesn't say "oh, I'll do that at some unspecified time in the future". This just sounds like a bug to me, plain and simple. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Thanks, Lee. I'll have a look. Is there a fractint.tmp file in your working directory? Jonathan

I've set up a batch mode test case where the disk video image (1514x1110 to adjust the time) generates in 3 minutes and 0.87 seconds. Using an automatic save time of 3 minutes performs one auto save and works fine for me. I was not doing anything else on the machine at the time. Is it possible you were doing something that was using the hard drive at the same time as the saves were occurring? Jonathan
