quick check of the code looks clean

[JohannesGGE]

There is something wrong with the background job.

UC1

• local_messages still contains entry

UC2

• works fine

UC3

• local_messages entry is not converted and remains in db

UC4

• works fine

UC5

• works fine

UC6

• UC1 -> works fine. local_messages entry seems to be deleted this time ('send_at' value is set)
• UC2 -> works fine
• UC3 -> local_messages up to date but not deleted. Draft in messages disappeared and no new updated version appears

[hamza221]

UC3 still missing

[ChristophWurst]

UC1: the drafts are stored locally. adding more text updates that draft. sending puts the message into the outbox. but the message is not sent.

UC2 ✔️

I think the only thing missing is starting a timer with the undo timeout and triggering a send of the new outbox message.

On systems with reliably cron the message will be sent after ~5mins. but I think the frontend should trigger sending right after the undo timeout.

@ChristophWurst what do you think should be done for UC3? should we handle it in a separate issue ?

[ChristophWurst]

Yes we can tackle UC3 separately

[hamza221]

The timer is already there but the message's sendAt was not updated correctly, Also I noticed that messages get enqueued when the draft is saved, I changed that too

[JohannesGGE]

With #8576 U3 works now.

I only noticed one small thing:
In UC5: When there is no change the composer doesn't close completly. The minimized composer stays. You have to click on close again on the minimized composer.

[hamza221]

Can you please give it another check. should be working properly now

[ChristophWurst]

Green CI. Time for a squash.
