How to generate the Aegis file?

It's not a Qt bug. It's QtCreator, which is 2.3.0 in the current QtSDK (1.1.3). See the bugreport's date, it should be fixed in the next patch release. I have to "git checkout" my .aegis file on every project opening ...

I see. Thus there was another trouble that I don't rememebr related to the aegis file also in the prevous version of Qt Creator. I meant Qt 4.7.4 and Qt 4.7.3 as the full SDK packages (including Qt Creator ).

Ok, it seems that there is a problem in the qt creator.

How can I generate the aegis file for the following libraries.

Contacts, SystemInfo, Multimedia, gallery

I think that when ever i changed the aegis file it will be cleared when i build the package using qt creator

Thank you for your help

For a detailed list take a look here: http://harmattan-dev.nokia.com/docs/library/html/guide/html/Developer_Library_Developing_for_Harmattan_Harmattan_security_Security_guide_Harmattan_APIs_that_require_credentials.html

Create the manifest.aegis file your own in qtc_packaging/debian_harmattan and be prepared the file gets cleared. So store a copy of it somewhere or use a versioning system. Check the file contents before packaging :)

bq. Finally I remembered where I have found about aegis: http://www.developer.nokia.com/Community/Wiki/Harmattan:Developer_Library/Developing_for_Harmattan/Harmattan_security/Security_guide/Aegis_manifest_file_generation_tool

It is in the Harmattan section of developer.nokia.com not on the developer network. I think this link may be helpful for you.

@gri: It is the second time that someone of us tells it to @mismael :) Seems that we are discussing alone :D

The developer.nokia.com site is much older than the harmattan-dev site. It also contains no reference to the list of credentials and is less structured in my point of view :) So it is not the same for me.

Edit: Ok, I was wrong, it has detailed information but different :) So it's better to look at both of them.

@gri: the question was about the owner of this thread :) ... I have seen your link for the first time today, nice! Thank you.

I tried to put the aegis file while qt creator packaging the application and i used the following credentials in it
@<aegis>
<request>
<credential name="TrackerReadAccess" />
<credential name="TrackerWriteAccess" />
<credential name="GRP::metadata-users" />
<credential name="GRP::pulse-access" />
<credential name="GRP::video" />
<credential name="mce::DeviceModeControl" />
<credential name="mce::TKLockControl" />
<for path="/usr/bin/userdatamanager" />
</request>
</aegis>@

but still the application does not execute because of the credentials.

Do you run the application with debugger attached or without? On the N950 beta1 firmware, there was an error where the applications' credentials are lost when running with debugger.

I don't know exactly which version the emulator is running. If the application works without the debugger, this may be the same.

In this case you would need to:

Login as developer via ssh
Execute "cat /etc/passwd | grep developer" and see if you read /bin/sh or /bin/develsh
If there is /bin/sh, become root and open "/etc/shells" with an editor, add "/bin/develsh"
Become developer again and run "chsh", choose "/bin/develsh"

I am running the application in the release mode

theoriginalgri · wrote on 26 Sept 2011, 11:52

Even in release mode you can run the debugger :) Please start the application with "CTRL + R" or the "Play" icon without overlay on bottom left to be sure.
Also take a look at the _aegis file in your project folder and tell me if it contains the lines you've written to your manifest.aegis.

If it does not work, I suppose the best idea would be to zip your code and upload it somewhere for testing. If you don't want to publish it to all, send me a private message with a link to the sources - I won't steal your code.

1- how can i get back to developer user (excuse me i am new to linux world)
2- when i tried to use "chch" as devel-su user it says that "chch" not found

thank you for your help

theoriginalgri · wrote on 26 Sept 2011, 14:15

You can check which user you are with "whoami". To become developer again from devel-su, you have to run "exit". The sign in front of your cursor also indicates who you are: "$" is user; "#" is root.

The command you have to run is "chsh", short for "change shell", not "chch". You have to add "/bin/develsh" to "/etc/shells" in order to be able to change the shell. Your favourite editor for editing might be "nano" (if available in emulator), which can be controlled by CTRL + "key number on the bottom of your screen".

If "chsh" is not available in the emulator, you can also change the entry of developer in "/etc/passwd" but be warned if you mess up the file, your emulator may not work anymore!

hi gri,

the _aegis file contains what i wrote in the *.aegis file.
I run the application with "CTRL + R"

theoriginalgri · wrote on 26 Sept 2011, 14:22

Ok, then I'm out of ideas now. Could you either provide a zip package with your code or the .deb file that I could test it on an actual device since I don't have the emulator?
