On the other end for programs doing things in background having a notification that they must shutdown isn't such a bad idea. For example imagine you have a process responsible for doing thumbnails of your videos, and this process runs in the background snooping for new files so you don't have to worry about that. This process can very well decide to start writing a new thumbnail at the very moment your are shutting down... A more realistic example would be YAM is started and is configured to retrieve your emails regularly...
I agree that ultimately that should be file-systems' responsibility to ensure consistency and integrity. But fact is we don't really have this currently or not completely because having a valid filesystem system does not ensure having the complete data on disk thus we still can end up with a validat/consistent filesystem but corrupted data from the application POV. We miss journalized filesystems with ability to revert files to previous uncorrupted version.
Another way of doing thing has been used by some soft reboot commands: locking each partition to prevent applications to start a write operation.

@ssolie

Yes a software shutdown can be a good idea. As I'm implicitly saying above I would even vote for a mechanism that can inform other applications that a software reboot is about to occur (maybe it can be using application library's features, maybe it can be using an evolution of the Olaf's shutdown.library (see Petah's post above), maybe it can be something else).

EDIT: But of course this should not be mandatory and ultimately there must be some sort of watchdog that would trigger the shutdown even if something is stuck after a decently long (configurable) period of time.

well, software shutdown means nothing more than "'pressing' the power button via software" to me - seeing it on amiga os.
and if i - instead of bending over and pressing the button on the computer case - could just press a "button" on my screen and the computer then would power off immediately... well - yes! that's what i want to have. for sure.

I'm all for this. I use it all the time in MorphOS, saves me moving the chair out and getting on the floor to find the tower under the desk, which is very awkward. Although, I have a feeling it may not work on the A1XE?

IMO, if application does not quicsave&close in about one second, OS should kill it without mercy.
+ user must have total control to set SW shutdown to work as one wants.
(minimum: people can use it also just to make system shutdown faster than ATX PSU physically otherwise allow)

And for applications: Support for SW shutdown & quicksave function should be made mandatory. And it must be stressed that one application can not use more than about one second to quicsave, we do not want the horrible SW shutdown of all main OSs, we want better.

@thread
I used HyperCache on my A4000 setup because onboard ide is not the fastest of the world (even though it's propably faster than on any 486/p1 HW).
Often when I made settings or saved something + powered off, I noticed that settings or files were not saved fully. (reason was that I wanted HyperCache wait for one second of CPU idle time before doing actual disk I/O or if not idle just delay a little or something)
If I had SW shutdown back then I would not have lost any data when using disk caching.

Absolutely, essential for the Netbook I would have thought.

yes, please. with the pegasos one has to hold down the power button for several seconds. not quite as satisfying as the instant-off of my SAM.

of course instant-on would always be better.

i think that if you're coming out with a netbook or (i really hope for someday) a bigger performance laptop, that you have to add software shutdown. for when battery reaches critical low level and things must be shut down in an orderly fashion before it's too late and you end up going dark in the middle od a disk write or something and you end up with invalidated disk, data lost that didnt get written from cache before going dark, or other sudden power loss problems.

For the netbook, I do not consider this as even optional, it simply must be. Same for any other laptop-alike that I'd love to see in the future. And for environmentally friendly power management on desktops as well.

mm. a killer feature planned for os4.2 release i take it? since im perfectly fine with turning my amiga off with the genuine power switch (or pulling a cord if need be) and passionately hate the windows power down feature that usually lets the pc hang around wating hours for some user input when its long assumed being off. so id rather like to hear about hows gallium and smp coming along. it must be fairly advanced by now, a little teaser would be nice.

No - you don't have to do that. Just use software shutdown: pegoff

Does this communicate with running software to tell them to save files, and wait for them to do so before issuing the reboot, or does the rug get pulled out from under anything running and things get lost?

All those saying it will save them reaching under the desk, are you expecting a software startup option too?

Also, I consider the need to hold down the power button for 5 seconds a bug. At least on PCs, I think the power button can be configured to do instant-off.

When I run it from Cubic IDE (I have a script that saves my current session to RAD:, handily available after the OS is restarted) it outputs information saying it closes down filesystems and waits for disk activity to finish. So it indeed does something along those lines.

I suppose you mean "proper" shut down - closing programs etc before powering off.
In this case, as long as it's optional (can be commented out in kicklayout for example), it's a very very good idea.

The point I was making is what appears to people from outside the Amiga community, users of Windows and Mac OS who might want to try Amiga OS will expect something like this.

We all know just hit the power button but those type of people would be horrified due to being told off next time they boot up

I think so. But the software shutdown option can't be just thrown together.
