Error after leaving a group related to chatroom

[taoeffect]

Problem

In my account on GIG, I was invited to join another group. Then I left that group. Some time later this error appeared:

[chelonia] ERROR 'Error' in processMutation for <op_ae|21XWnNPCeyhCGgatyS7JHAjT1sjMetSyNTCPeKKaMxRvLWKkdW of 21XWnNHw72vW9p4KbNLXggv827ByRJM2iiBVyhLZuEBkwUGCbD>: Can not leave the chatroom which greg are not part of Error: Can not leave the chatroom which greg are not part of

Solution

Find and fix the problem.

@taoeffect, can you please upload the groupincome.db which makes this error? I tried many times in different cases, I can not produce that error.

PS: The previous database file groupincome.db doesn't make this error.

[Silver-IT]

With this database(groupincome.db) you provided through DM recently, I can not produce the error your pointed.

[taoeffect]

@Silver-IT Let's go over this when you get back, as this is a fairly high-priority issue and we need to make sure we can fix this.

[Silver-IT]

Using the groupincome.db, I didn't get the error which is described here in this issue but I got another error.

Finally, I met the error and noticed that two gi.contracts/chatroom/leave messages are created.

[Silver-IT]

Oh, no. It's weird actually. I did produce that error only ONCE yesterday, and can not reproduce that error again yet.
It's needed to try more, but I guess this issue is related to the time taken to sync the contract (group or chatroom, not sure).

[Silver-IT]

YES. Finally, I got this error again and I can share the steps to reproduce. It's easy to reproduce this error using Multi-Container Addon in Firefox. Let's say we have three tabs (tab1, tab2, tab3) with different session.

Steps to reproduce

• tab1: user1 creates a group
• tab2: user1 logs in (so totally two sessions for user1)
• tab3: user2 joins the group
• tab1: user1 leaves the group
• tab3: BANG

Since this issue is related to low-level details @corrideat is working on, I've reassigned him to it
