users-admin has significantly delayed response after clicking OK

[Paddy Launch]

Binary package hint: gnome-system-tools

Possible duplicate of #542744 ?

Ubuntu 10.04 Beta 1.

When using the users-admin tool from gnome-system-tools, every instance of clicking on an 'OK' button causes the application to pause/freeze/delay for 10-20 seconds before completing the intended action, even if the action is not actually causing any change to data.

E.g. I click on Advanced Settings (for the current user), and then Authenticate. I click on the User Privileges tab, and then 'OK'. There is no response for several seconds before the dialog finally disappears. I then click Manage Groups, and examine the properties of any group, e.g. Audio - when I click 'OK' to close the dialog there is no response for 10-20 seconds before the dialog finally closes.

Yes, I see what you're talking about. And no, that's not a duplicate of bug 542744 (there, committing leads to an error message).

What happens is that we don't check for actual changes when you click OK, we always commit changes. Everytime groups are involved, we commit changes to all groups, which takes some time.

In the upcoming 2.10.0 version, the system-tools-backends don't apply changes when nothing has actually changed. This makes most operations must faster, especially when no changes were made at all. Plus, we no longer reload settings for each separate group commit. So I consider this fixed upstream, it should be in Lucid soon.

The delay is one thing, but it's the not having any visual feedback (e.g. busy icon) that's most disconcerting, as you don't know whether or not your click has been registered, or whether or not the app has completely locked up!

[Milan Bouchet-Valat (nalimilan)]

Sure, but you don't need feedback when the operation takes one second instead of 20.

Fixed with 2.10.0 in Maverick (delays are much shorter). Waiting for a Lucid backport.

Accepted system-tools-backends into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Any testers of the lucid-proposed package? As this has been in -proposed for a long time already, I'll remove the proposed package soon if there is no feedback. Thank you!

OK, I guess as I'm the only person this bug affects, the task falls to
me ;)

I have installed the lucid-proposed update and tested it - the bug
appears to have been fixed, there is no longer any significant delay
after clicking "OK" in supervisor mode.

This bug was fixed in the package system-tools-backends - 2.9.4-0ubuntu1.1
