sapling/tests/test-repo-leak.t

Test native objects attached to the "repo" object gets properly released at the
end of process.

Attach an object with `__del__` to learn whether repo, ui are dropped on not.

  $ cat > $TESTTMP/printondel.py << EOF
  > class printondel(object):
  >     def __del__(self):
  >         print("__del__ called")
  > def reposetup(ui, repo):
  >     obj = printondel()
  >     repo._deltest = obj
  >     ui._deltest = obj
  > EOF

fsmonitor would cause leaks

#require no-fsmonitor

No leak without extensions
