comment:5 Changed 7 months ago by
I have no idea what the problem was. Until this is resolved, I propose to remove the inheritance and implement the immutability manually, see last commit.

I think it would be better to rebase it, removing the reverted commit and the reverting commit.

Replying to mkoeppe:

Like this? I hope everything worked out during the rebase.
comment:15 Changed 7 months ago by
No, apparently not...I hate rebasing...

Damn it...
comment:18 Changed 7 months ago by
Can you fix this? Please? :/
I don't even know what went wrong during the rebase. The last commit is somehow missing, but it shouldn't.
Then I messed it up by merging that last commit again. That was stupid.

Sure, let me take a look

Thanks! May I ask how you did it?
comment:24 Changed 7 months ago by
I got really weird merge conflicts when trying to do git rebase i
, so I just squashed everything on top of #30285 by doing git trac fetch 30285 && git reset FETCH_HEAD && git commit a
.

Two things are strange here. First, the test suite starts a pickling test, that didn't happen before. Secondly, for some reason
is_immutable()
does not invoke properly. The doctests fail.I have uploaded my code. Can someone please take a short look?
