This commit improves the management of script execution process by enhancing the way terminal commands are handled, paving the way for easier future modifications and providing clearer feedback to users when scripts are cancelled. Previously, the UI displayed a generic error message which could lead to confusion if the user intentionally cancelled the script execution. Now, a specific error dialog will appear, improving the user experience by accurately reflecting the action taken by the user. This change affects code execution on Linux where closing GNOME terminal returns exit code `137` which is then treated by script cancellation by privacy.sexy to show the accurate error dialog. It does not affect macOS and Windows as curret commands result in success (`0`) exit code on cancellation. Additionally, this update encapsulates OS-specific logic into dedicated classes, promoting better separation of concerns and increasing the modularity of the codebase. This makes it simpler to maintain and extend the application. Key changes: - Display a specific error message for script cancellations. - Refactor command execution into dedicated classes. - Improve file permission setting flexibility and avoid setting file permissions on Windows as it's not required to execute files. - Introduce more granular error types for script execution. - Increase logging for shell commands to aid in debugging. - Expand test coverage to ensure reliability. - Fix error dialogs not showing the error messages due to incorrect propagation of errors. Other supported changes: - Update `SECURITY.md` with details on script readback and verification. - Fix a typo in `IpcRegistration.spec.ts`. - Document antivirus scans in `desktop-vs-web-features.md`.

🤔 Potential improvements:
|
|
Use user-friendly GUI sudo prompt (not terminal-based).
|
|
If `pkexec` exists, we could do `x-terminal-emulator -e pkexec 'path'`, which always
|
|
prompts with user-friendly GUI sudo prompt.
|
|
📝 Options:
|
|
`x-terminal-emulator -e 'path'`:
|
|
✅ Visible terminal window
|
|
❌ Terminal-based (not GUI) sudo prompt.
|
|
`x-terminal-emulator -e pkexec 'path'
|
|
✅ Visible terminal window
|
|
✅ Always prompts with user-friendly GUI sudo prompt.
|
|
🤔 Not using `pkexec` as it is not in all Linux distributions. It should have smarter
|
|
logic to handle if it does not exist.
|
|
`electron.shell.openPath`:
|
|
❌ Opens the script in the default text editor, verified on
|
|
Debian/Ubuntu-based distributions.
|
|
`child_process.execFile()`:
|
|
❌ Script execution in the background without a visible terminal.

`x-terminal-emulator` may return exit code `137` under specific circumstances like when the

user closes the terminal (observed with `gnome-terminal` on Pop!_OS). This exit code (128 +

Unix signal 9) indicates the process was terminated by a SIGKILL signal, which can occur due

to user action (cancelling the progress) or the system (e.g., due to memory shortages).

Additional exit codes noted for future consideration (currently not handled as they have not

been reproduced):
|
|
|

- 130 (130 = 128 + Unix signal 2): Indicates the script was terminated by the user

- 143 (128 + Unix signal 15): Indicates termination by a SIGTERM signal, suggesting a request
