Saved activities are not preserved across app restarts

rebos commented 1 year ago

After upgrading an Xperia XA2 to Sailfish OS 4.5.0.18 (Struven ketju) I encountered a problem with the process of saving activites using Laufhelden 1.1.4-1: Although the saving process seems to have been successful I do not see any saved activites after closing the app and starting it again.

To reproduce the observed behaviour I followed these steps:

Start the app by tapping the icon
Start an activity
Stop the activity
Save the activity which seems to have been successful
Close the app
Start the app again by tapping the icon
See no saved activites

Trying to get some more information about this I launched a terminal session and started the app by calling the corresponding command to get some debug messages: harbour-laufhelden

I was suprised to discover that this session of Laufhelden started via terminal worked perfectly as suspected: Saving an activity led to an existing file which persisted even after closing the app and starting it again: grafik

Performing further attempts to find the differences between both starting methods I realized, that it has something to do with the variable HOME. Unsetting HOME within the terminal session leads to the problem that saved activities are not preserved across app restarts. I could reproduce this by issuing these commands in a terminal session:

unset HOME
harbour-laufhelden

Maybe these observations help to fix the root cause.

Hmm. I have checked the code and the activities are saved to the QStandardPaths::writableLocation(QStandardPaths::HomeLocation) folder which should be correct. In your first attempt did the log files created in the $HOME/Laufhelden?

Unfortunately I did not find any log files created by the app.

To get some interactive logging I started the app by clicking the icon und tried to identify the corresponding process in a console session by using "ps". That led me to an invocation of "firejail" which seems to have started "harbor-laufhelden". I then transformed that command and it's arguments to a more readable variant and removed the argument "--quiet". This gave me the following command, which I saved in a script file:

/usr/bin/firejail \
--private-bin=harbour-laufhelden  \
--whitelist=/usr/share/harbour-laufhelden  \
--whitelist=/usr/share/applications/harbour-laufhelden.desktop  \
--mkdir=${HOME}/.local/share/harbour-laufhelden  \
--whitelist=${HOME}/.local/share/harbour-laufhelden  \
--mkdir=${HOME}/.config/harbour-laufhelden  \
--whitelist=${HOME}/.config/harbour-laufhelden  \
--mkdir=${HOME}/.cache/harbour-laufhelden  \
--whitelist=${HOME}/.cache/harbour-laufhelden  \
--profile=/etc/sailjail/permissions/Audio.permission  \
--profile=/etc/sailjail/permissions/Bluetooth.permission  \
--profile=/etc/sailjail/permissions/Camera.permission  \
--profile=/etc/sailjail/permissions/Compatibility.permission  \
--profile=/etc/sailjail/permissions/Internet.permission  \
--profile=/etc/sailjail/permissions/Location.permission  \
--profile=/etc/sailjail/permissions/MediaIndexing.permission  \
--profile=/etc/sailjail/permissions/Microphone.permission  \
--profile=/etc/sailjail/permissions/NFC.permission  \
--profile=/etc/sailjail/permissions/RemovableMedia.permission  \
--profile=/etc/sailjail/permissions/UserDirs.permission  \
--profile=/etc/sailjail/permissions/WebView.permission  \
--profile=/etc/sailjail/permissions/Base.permission  \
-- /usr/bin/harbour-laufhelden

Executing this script when no instance of "harbour-laufhelden" was running started a new process and showed a lot of messages. I think the most interesting ones could be those, which I saw directly after saving an activity:

Two aspects caught my attention: One message suggests, that the directory "/home/defaultuser/Laufhelden" does not exist. But it does exist and contains to files created the day before yesterday:

[defaultuser@XperiaXA2-DualSIM ~]$ ls -lh /home/defaultuser/Laufhelden/
total 20K
-rw-rw-r--    1 defaultu defaultu     326 Mar 12 17:23 AccelerationHelper.dat
-rw-rw-r--    1 defaultu defaultu    6.3K Mar 12 16:44 walking-So. März 12 16:44:15 2023-0.0km.gpx
-rw-rw-r--    1 defaultu defaultu    6.3K Mar 12 17:23 walking-So. März 12 17:23:04 2023-0.0km.gpx
[defaultuser@XperiaXA2-DualSIM ~]$

Another messages suggests, that the file "walking-Di. März 14 12:25:51 2023-0.0km.gpx" was successfully written. So I should be able to find it, but unfortunately I can't:

[defaultuser@XperiaXA2-DualSIM ~]$ pwd
/home/defaultuser
[defaultuser@XperiaXA2-DualSIM ~]$ find . -name "walking-Di. März 14 12:25:51 2023-0.0km.gpx"
find: ./.config/signond: Permission denied
find: ./.local/share/system/privileged: Permission denied
[defaultuser@XperiaXA2-DualSIM ~]$

I can't even find it running "find" on the whole filesystem after using "devel-su".

So, as far as I can put it together now, starting "harbour-laufhelden" in a terminal session works as expected, but starting it in a terminal session using the firejail invocation does not (at least on my system).
