Broken network handling in python application

Creating AppImages
1

Hello,

I am trying to create a proper AppImage package for the app activitywatch.

The package seems to be fine, but when I try to open .AppImage file I got I get errors:

ConnectionAbortedError: [Errno 103] Software caused connection abort: '/tmp/.mount_ActiviFn6gM2/aw-watcher-window/aw-watcher-window'
...
OSError: [Errno 107] Transport endpoint is not connected: '/tmp/.mount_ActiviFn6gM2/aw-watcher-afk/aw-watcher-afk'
...
ImportError: Loader FrozenImporter cannot handle module http.client

The above exception was the direct cause of the following exception:

It seems to be a network-related error.
The same app launched without AppImage works properly.

What can I do to fix it?

Example for quick reproduction:

wget https://github.com/ActivityWatch/activitywatch/releases/download/v0.12.0/activitywatch-v0.12.0-linux-x86_64.zip
ZIP_FILE=`ls ./ -1 |grep zip`
unzip ./$ZIP_FILE
#Launching ./activitywatch/aw-qt # Now would be successful
wget https://github.com/linuxdeploy/linuxdeploy/releases/download/continuous/linuxdeploy-x86_64.AppImage
chmod +x linuxdeploy-x86_64.AppImage
wget https://github.com/AppImage/AppImageKit/releases/download/continuous/appimagetool-x86_64.AppImage
chmod +x appimagetool-x86_64.AppImage
echo '#!/bin/sh
DIR="$(dirname "$(readlink -f "${0}")")"
"${DIR}"/aw-qt'>activitywatch/AppRun
chmod a+x ./activitywatch/AppRun
./linuxdeploy-x86_64.AppImage --appdir activitywatch --executable ./activitywatch/aw-qt --output appimage --desktop-file ./activitywatch/aw-qt.desktop --icon-file ./activitywatch/aw-server-rust/static/static/logo.png --icon-filename activitywatch

Can it be caused by usage of multiple executables?

Application aw-qt calls apps aw-server, aw-watcher-window and aw-watcher-afk.

Hello, I don’t know how that application works.
Please ask the team over at GitHub - ActivityWatch/activitywatch: The best free and open-source automated time tracker. Cross-platform, extensible, privacy-focused. to release an officially supported AppImage. Thanks!

I am the one, who prepares the release of that officially supported AppImage :slight_smile:

Could you tell me what is the difference between ragular way of launching appimage

./ActivityWatch-x86_64.AppImage --appimage-mount

and mounting it and launching AppRun file?

./ActivityWatch-x86_64.AppImage --appimage-mount

cd /tmp/.mount_Activi72i8d6
./AppRun

Because doing it in the second way launches app properly.

Can it be that your application exits a process (and then possibly starts another process)? As soon as the AppRun process exits, the AppImage gets unmounted.
