cool, which version are you using?

if you try the previous gstreamer command in x-term, do you get any error messages?

Re: [Maemo 5] HealthCheck - Pymaemo/Qt - Learning to code (N900)

i have version 0.5.0-2

just opend it agen the front cam does work but is very dark

all you will have to do now is add a tab to free the space in the root, like moves fonts and so on.

Back to front? - it acts as a mirror image i think.

hiMackan, sorry doing the updates in the other post :) - getting a bit confusing having it in two!

Was just a quick test, works on mine, but i'll figure out why not on others :)

No idea what i'm putton on that page yet, so not concentrating on layout until i know what i need to lay out.

Re: [Maemo 5] HealthCheck - Pymaemo/Qt - Learning to code (N900)

Hey everyone, coding question....

Looking at calling some commands that need root on the device....
running this command on my phone via my python app works... but doesn't seem to work elsewhere....

Code:

sudo /sbin/reboot

Should i
a) not be calling commands like this.... (Would kinda scupper my plans!!)
b) be doing it a different way
c) something else... lol

It works here as well - it may depend on rootsh having been installed.

Re: [Maemo 5] HealthCheck - Pymaemo/Qt - Learning to code (N900)

I think that will depend if you guys have modified your sudoers file for something else previously.

Normally I don't think running sudo "command" on the N900 will work even with rootsh..

Rootsh allows you to run "sudo gainroot" to get root, then the command. Sudo <commands> still ask for a password (in my understanding.)

So what you would want normally I think would be something like:

Code:

echo /sbin/reboot | sudo gainroot

and depend your app on rootsh.. although I don't think depending on rootsh is a good idea.

There must be some kind of API in dbus or somewhere to tell the device to reboot properly instead of running shell commands.

Precisely. Place a file in /etc/sudoers.d with a command that you want whitelisted for running as root via sudo (standard sudoers syntax), instead, and run "update-sudoers" in the postinst and postrm scripts of the package.

Code:

run-standalone.sh dbus-send --system --type=method_call --dest="com.nokia.mce" --print-reply "/com/nokia/mce/request" com.nokia.mce.request.req_reboot

Put the equivalent of that into your favourite solution for using D-Bus in an app (DBus-GLib, libosso, python-osso, python-dbus, libdbus, QDBus, ..)
http://maemo.org/api_refs/5.0/5.0-fi...-names_8h.html explains some more of the method calls available to you.

Apologies. It got moved to DSME. Try:

apt-get install pymaemo-optify (possibly)

even looking at using the cleanup script to run externally as part of the application....

ok, right tidied up the app ready to lean this bit.....
I'm going to sound incredibly noobish... (Tis all in the name i say!)......

Quote:

I'm assuming that means for example if i want to run apt-get clean
It needs to be added somehow to /etc/sudoers.d

Not sure what you mean by -

Quote:

My package is pretty simple... 2 py files and the usual desktop, service and icons...

Re: [Maemo 5] HealthCheck - Pymaemo/Qt - Learning to code (N900)

two files in debian control

postinst & postrm

Code:

#!/bin/sh



#update sudoers



update-sudoers

create the following file

etc/sudoers.d/healthcheck.sudoers

Code:

user ALL = NOPASSWD: /<path>/command

put all the commands you need to run as root.

this will allow commands to be run as root when your package is installed, and stopped when package is removed.

Re: [Maemo 5] HealthCheck - Pymaemo/Qt - Learning to code (N900)

ok... getting there i think now...
SO for example my sudoers file would for example look like this?

user ALL = NOPASSWD: /apt-get %users ALL = NOPASSWD: /sbin/reboot

i'm assuming id i put apt-get in there, i can use all apt-get commands if needed?
(Just tring to find apt-get so i can put it in the right path...

Now.....

Quote:

No idea what you mean, as when i package i then use autobuilder - and tbh - never heard of debian control etc... (Really new to linux and python, sorry)

But the code looks just like something i need to put in a file!..

Code:

#!/bin/sh



#update sudoers



update-sudoers

So am i right i nthinking i need to create a postinst & postrm file with this code in it? ... if so, where do i put these files, and how to they get run? (Auto by app manager?)

Sorry for the multiple q's!

postinst & postrm go in /DEBIAN folder in your package folder structure.

Re: [Maemo 5] HealthCheck - Pymaemo/Qt - Learning to code (N900)

hmmmmm need some help peoples... (no change here then!)

At the moment i read the firmware versions and return something like PR1.1 - or PR1.1.1 ....
Quite easy to do at the moment... but i will hit a snag when new firmware versions come out, as i will have to update the code, then wait the 10+ days to get it out to people.... Not much help...

A few way rounds i can think of are....
Listing the versions on my website and parsing it directly from there (not good if people dont have or want to use the internet.)

or

Giving the user the ability to download a text file with them listed in, and update when they want.

Are there any other ways people can think off? or any previous good examples?
