Introducing the Rear Window blog

@trixie

The latest version of AmigaDiskBench (v. 2.5.3) seems to have a very similar bug as Rave: When I run the program, select the Disk Info tab, and then click on "Fixed Drives/sb600sata.device" in the listview the program stops responding, along with much of the OS. (There is a recoverable DSI when I first run the program; that DSI doesn't seem related to the lockup bug.)

Like Rave, the crash happens when the program is working with ReAction gadgets, and the stack trace shows the crash occurs during a series of nested calls to the layout.gadget, followed by a call to the button.gadget. The first part of the crash log, including the general info and the register dump, seems to go missing. But what remains is enough to get an idea what was happening when the crash occurred:


The exact code where the crash occurs is different than Rave. There are some other differences as well: unlike Rave, the crash occurs under FE Update 2, as well as under Update 3. And unlike Rave, the crash occurs even if AmigaDiskBench is run from the RAM disk. While the crash occurs most of the time, it occasionally doesn't, unlike Rave where it is always repeatable. Since I have only an X1000, I can't say if the crash only occurs on the X1000, as it does with Rave.

AmigaDiskBench isn't your responsibility, but the fact that a very similar bug occurs there is some evidence that it's not caused by your code doing anything wrong, and may in fact be a system problem of some sort. And perhaps the differences between the Rave crash and the AmigaDiskBench crash provide some clues as to where the problem lies.

@all

With the help of Niels Bache, the X1000-only crash has been fixed for Rave 1.10.

Thank to both of you!

With all the weird symptoms, I'm curious what the problem turned out to be.

It was a race condition. More details in my next blog post

@trixie

Hi threr is another issue:
When clicking (click or click and drag) on right side border of waveform preview/gadget the apps crashes/freezes system.

@trixie

For next release could you add support for localization?

I tried to reproduce it, but couldn't. But I'm not sure I understand exactly where you click/drag. Can you show it in a screen grab or something?

Also, that is on a Sam460, IIRC?


Best regards,

Niels

@jabirulo

I can't reproduce this either. However, I reviewed the waveform gadget's selection hook, and I found a situation similar to the one that caused the race condition in the Settings, so I applied the same kind of fix just to be on the safe side.

when click on green zone and dragging to select a "part" of (previewed) sample here it freezes.

SAM460ex

@jabirulo

Yeah, that's what I thought you meant. So no, I couldn't reproduce that either.

So maybe it is/was specific for Sam460? Since we are in the murky waters of timing issues, that wouldn't be completely impossible, as it has yet another speed than the X1000 and X5000 which we tested on so far.

Best regards,

Niels

@nbache @jabirulo

I'll send a test build to both of you before releasing Rave 1.10.

@trixie

ok thx

This should now be fixed too for Rave 1.10.

@all

Rave 1.10 has been released on OS4depot. I'd like to thank users who reported problems with the previous version - above all, Mike Steed, Niels Bache, and Javier de las Rivas - and helped with the testing.

As usual, there is an article on my Ko-fi blog that tells the story behind the current release. If you like what I've done and want to support my efforts, I won't say no to a coffee

Thank you, and enjoy!

@trixie

Thanks for the update.
