Delete action of notifications always the same

[Cigaes]

Problem description

With Termux:API 0.51.0 from F-Droid, the --on-delete option to termux-notification only works the first time: the next times, it will always execute the same command.

Steps to reproduce

• Run this command:

termux-notification --id testid --title testtitle --content testcontent --on-delete "echo $(date) > $TTY"

• Discard the notification: the date appears in the terminal.
• Re-run the command, re-dicard the notification.

Expected behavior: a more recent date appears in the terminal.

Observed behavior: the same date appears in the terminal.

Changing the id, the title do not help, nor using a completely different action. Forcing stop on Termux and Termux:API do not help. Only rebooting resets the action.

It used to work with 0.50.1.

Technical info

• termux-api application version: 0.51.0 from F-Droid
• termux-api package version (installed through apt): 0.59.1
• Android OS version: 13 (LineageOS 20-20231222-NIGHTLY-Lynx)
• Device model: Google Pixel 7A

Thanks in advance.

This is true for all of the button actions as well (--button1-action etc.), not just --on-delete.

Not only of all actions in a single run, but across completely different executions.
I myself am trying to whisk a very basic process monitoring tool with the following one-liner:

watch -n1 "su -c top -bqo '%CPU,PID,CMDLINE' -n1 -s1 -m1 | grep -v top | cut -d ' ' -f -5 | termux-notification --group Stats --priority low --ongoing -i 69420 -t 'CPU Usage' --button1 'Terminate PID' --button1-action 'su -c kill \$REPLY' --button2 'Restart SysUI' --button2-action 'su -c killall com.android.systemui' --button3 'Restart SurfaceFlinger' --button3-action 'su -c killall surfaceflinger' --on-delete 'killall watch'"

All three buttons and notification dismissal run su -c killall com.android.systemui, that is button 2's action.

However, I then did some further testing to avoid using watch, as I was getting spammed with superuser notification toasts, trying this simple script:

date | termux-notification --group Tests --priority low --ongoing -i 7331 -t 'Test' --action `realpath $0`

(Shebang deliberately omitted)

Yet it still runs su -c killall com.android.systemui! Even when it's a different shell session, notification id, group, everything!

Edit:
After a restart the last script worked as written not really as intended; I needed to use realpath to recursively call the script; I corrected the code above. The general behavior of the actions is still very much broken as described.
Also I took a quick look at the source code of this app as well as the package; as far as I can see there's nothing obviously wrong in the code that would indicate that the same action is called everytime. I am not, however, a Java dev, much less an Android one, so I feel like when going from shell scripts to C to Java, my grasp kept diminishing.
