Once this is merged ill create a new PR because my master branch also has these commits so any branch i create is ahead of the upstream so ill have a bit problems

[ThomasWaldmann]

You should always keep your master branch clean (representing and in sync with upstream master), then things get way easier and you don't block yourself.

[div-dev123]

Yeah I realised that now , its just that first time for all this so made a little mistakes. But thanks so much for you patience !

[div-dev123]

@ThomasWaldmann can you squash the commits for this?

[ThomasWaldmann]

@div-dev123 can you also do a backport of this to 1.4-maint branch?

[div-dev123]

Can you tell me how to do that? Like should i just push this commit there ? wont there be conflicts?

[ThomasWaldmann]

You can use git cherry-pick for that. Sometimes, there will be conflicts, sometimes not. Conflicts need to get resolved manually.

[ThomasWaldmann]

@div-dev123 are you still working on the backport?

[div-dev123]

I have my exams till Friday, I can work after that but if anyone wants to work on it they can!

[ThomasWaldmann]

I'll work on the 1.4 backport now...
