shutdown status "application input_server might be blocked on a modal panel"

[dfourth]

recently updated system from R1A4.1 to hrev45085 and began receiving this message on every shutdown. It seems to have reappeared, as I noticed an older closed bug (#1491 I believe) from 2007. I have only been using Haiku since R1A3 and this is the first time I've noticed it.

My system: AMD Phenom II 2.59 GHz 6 processors 6143MiB memory, 5% used by system Kernel dated Dec 25 2012 00:35:07

This may only happen if there are more than one input_server on the disk, and the wrong one is chosen for whatever reason (ie. one that is not in /system). Removing that second instance should fix the issue for you.

Whether or not this is a bug in Haiku depends on how you updated. If you just renamed the /system folder (not copied it), and replaced it with the one from hrev45085 things like this might actually happen without the system being able to notice.

(In #9329) Inadvertent duplicate.

That is indeed the method used to update the system, as it seemed the most straightforward for real hardware (based on my readings from the Haiku.org website) without requiring a CD to be burned etc. The old system folder has been moved off to a backup partition that is not mounted. Tracker's Find can only locate a single instance of input_server, and only one instance is found when viewing running processes. Repeated power cycles without starting any additional applications results in the same error at shutdown each time. If there is a second instance of input_server anywhere in the system, I am unable to locate it. I have attached my device and driver list, should it be of any value.

[axeld]

That's interesting, thanks for the update. The message should only come if Haiku does not recognize the input_server as a system component. Apparently, that check fails for you for whatever reason. The shutdown process checks if the app is in /system/app or /system/server, and won't ask the user if this is the case.

Could you please attach the output of the roster command?

Any clues from this?

Curiouser and curiouser... after posting the results from the roster command, the subsequent shutdown did NOT produce the input_server error. As is was after 3am my time, I let it go and went to bed. Upon starting this up this morning, I immediately shut it down and again observered no input_server error message. I have no idea what might have changed or if this is an intermittent problem. Either way, it isn't possible to debug something that isn't showing symptoms, so I imagine it would be best to end this ticket and possibly resurrect it if the issue pops up again.

[Karvjorm]

I have this problem also and I think it started when I tested MsgSpy and it was installed in ~/config/add-ons/input_server/filters/

Then I removed MsgSpy, but PortSpy is still there and this problem occurs during each shutdown. I have supposed, that input_server filters cannot handle shutdown messages.

[Karvjorm]

No, I removed PortSpy, but input_server shutdown problem is still left.

[Karvjorm]

OK, it looks like input_server is not a system component just like Deskbar, media_addon_server and sshd. I have some problem during startup and I have to restart Deskbar via ctr-alt-del window.

[Karvjorm]

This is my syslog

[axeld]

Karvjorm, could you also provide the output of the roster command?

There are two strange details in my system. First, I once tested PowerStatus replicant, and aborted it (if I recall it correct) because there was already a PowerStatus replicant on Deskbar. But anyway, I got a battery outline on my desktop (and it is still there though I have surely upgrade Haiku twice after it. Could this battery outline be that blocking component? I do not know any way to remove it.

During another test some test program placed another replicant on the Deskbar and I cannot remove it either. I can't remember what replicant it was, some in src/test source code branch.

[Karvjorm]

Non-removable powerstatus shown by cursor and another replicant right to network status

[Karvjorm]

I wonder if the Deskbar settings would show all the present replicants on Deskbar. And then it would provide some radio buttons to remove them one by one.

[Karvjorm]

The Quit menu line does not work, if I select it in my Desktop PowerStatus. If I turn off "Show text label/Show status icon/Show time" menu lines, PowerStatus replicant disappears, but it is still there if I click the correct coordinate of the Desktop with the mouse cursor.

[Karvjorm]

OK, when I turned on "Show replicants" in Deskbar menu, I was able to see a PowerStatus handle quite far away from the battery outline. And by clicking that handle I was able to close Phantom PowerStatus on my Desktop and it is gone now. But input_server shutdown problem is still there. My working method is always trial-and-error. ;-)
