Subject: trees extension doesn't work with hg 3.8.3

*** failed to import extension trees from trees/trees.py: 'module' object has no attribute 'norepo'
hg: unknown command 'tclone'
(did you mean clone?)

It works fine with Mercurial 3.5.2 so it seems like the commands.norepo and commands.optionalrepo attributes were removed in between.

I ran into the same issue recently and found :

CODETOOLS-7901672 "trees extension broken after upgrade to mercurial 3.8.1"
https://bugs.openjdk.java.net/browse/CODETOOLS-7901672

There are patches on the report.

Hope this helps-

Tim
