The plugin hooks pytest_cmdline_parse and pytest_load_initial_conftests don't appear to get called #2616
Description
I have a conftest.py I've been using to try to test the available hook functions.
import pytest
print('conftest.py')
def pytest_load_initial_conftests(early_config, parser, args):
print(early_config)
print(parser)
print(args)
def pytest_cmdline_parse(pluginmanager, args):
print(pluginmanager)
print(args)
def pytest_cmdline_main(config):
print(config)
def pytest_cmdline_preparse(config, args):
print(config)
print(args)The values for pytest_cmdline_main and pytest_cmdline_preparse never get printed, so I think they're not being called. When I look in the debugger, the latter hooks seem to be called by the line

'_pytest.config'The only hook at this point is _pytest.config.Config.pytest_cmdline_parse, which gets called. Later on, the hook in my conftest.py is added, but I don't think this list of hooks is examined again after this initial call. Having __init__.py in the directory or not doesn't seem to matter, the first two hooks don't get executed. I haven't checked more complicated possible package configurations.
If this is intended behavior, it's not very transparent, and the documentation doesn't explain what's needed to get the first two hooks actually called.
