wireprotoserver: don't import symbol from hgweb.common Importing hgweb.common requires importing hgweb. hgweb/__init__.py contains a bit of code and does imports of large parts of the hgweb.* module tree. All we need is a constant defining the integer status code for HTTP OK. So just redefine HTTP_OK in wireprotoserver.py and avoid the excessive imports.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
