Critical bug with subscriber deletion

[roshanjonah]

Version:

• listmonk: v1.0.0
• OS: Ubuntu

Description of the bug and steps to reproduce:

• Create two different lists preferably with two different sets of subscribers
• Go to one of the lists and check the first checkbox to select all first page subscribers
• Once options appear at the top, choose the "Select all xx subscribers" option
• Click on "Delete"

Wait for a bit and all the subscribers across all the lists get deleted. Not just the one in the list you selected.

What it should be doing?

• Deleting only the subscribers selected across the pages in that list alone - not across all the lists.

This is expected behaviour.

A subscriber is a first class citizen entity that is connected to lists via subscriptions (table: subscriber_lists [subscriber_id, list_id]). When you delete a subscriber, you're wiping the entity off the database including all their relationships. To remove a subscriber from the list, you've to edit the subscriber and remove the particular list relationship and not delete the subscriber itself.

The screenshot is of the global list of subscribers filtered by a list and the UI and the beahviour is consistent with the "All subscribers" view as well.

Oh! The above screenshot is actually a specific list view. I kind of understand that but still don't understand why all subscribers have to be deleted when the list only contains 59. I had two lists in the system. One list had 150,000 emails and the second list which you see here had 59. So when I selected the option "Select all 59" and click "Delete", I don't understand why it would delete the 150k as well as the 59 I selected here in this specific list. 😕

Not sure if I am explaining correctly but happy to explain it another way @knadh

Ah, this wasn't apparent in your original description. If all subscribers got deleted and not just the ones you selected on the UI (59), it's a bug.

I hope you had a backup 🤯

Nope didn't have it and it was all wiped clean and since all tables are linked via IDs - it didn't help with any other data in the DB. Pretty terrible place to be so thought I'd notify you guys right away hoping nobody else loses their data this way 👍 Def learned my lesson of having working backups - took it lightly

Argh ;( Will investigate and fix this today. Terrible.

This is fixed. Will do a new release tomorrow with this and a couple of other things.
