Problem summary The last deleted Channel is still accessible via Python
Customer reported version
Mari 5.0v4
Customer reported platform
CentOS 7
Steps to reproduce
1) Open any project
2) Create three Channel nodes: Channel1, Channel2, and Channel3
3) Delete Channel3
4) Run the following script to get a list of Channels in the projects and their names:
print(mari.geo.current().channelList())for c in mari.geo.current().channelList(): print(c.name())
Expected behaviour
Only Channel1 and Channel2 should be returned:
[<mari.Channel(0x1dba7c54e20) at 0x000001DB3133BD00>, <mari.Channel(0x1dba7c54bb0) at 0x000001DB31372A40>]
Channel1
Channel2
Actual behaviour
Channel3 also gets returned:
[<mari.Channel(0x1dba7c54e20) at 0x000001DB3133BD00>, <mari.Channel(0x1dba7c54bb0) at 0x000001DB31372A40>, <mari.Channel(0x1dba7c442c0) at 0x000001DB3137F180>]
Channel1
Channel2
Channel3
If the user now deletes Channel2 and runs the script again: Channel3 doesn't get returned, but Channel2 does.
If the user deleted multiple Channels at once, only one of them still gets returned.
Workaround
Saving, closing and reopening your Project will fully remove the deleted Channels.
Additionally, creating a new Channel also fully updates the channelList.
