It doesn't do much. The logging stuff has some customizations (in
paste.script.util.logging_config), but I must admit I don't know quite
what they are about; Philip Jenvy did those.
This sounds like something to do with the actual application loading
(any logging stuff isn't being loaded at all). paster serve really
doesn't do much there. It adds 'config:' to the start of the config
file if you don't give it, and can take an explicit app name/section
argument (instead of #section) and passes that as the 'name' keyword to
loadapp. But that's it. It might be hard to see in all the
daemonization, reloading, etc stuff in paster serve, but the actual
loading and serving of apps is just a very small bit of code.
Out of curiosity, I grabbed the original version of the command (just
the implementation) before it grew so large:
def command(self):
app_spec = self.args[0]
app_name = self.options.app_name
if not self._scheme_re.search(app_spec):
app_spec = 'config:' + app_spec
server_name = self.options.server_name
if self.options.server:
server_spec = 'egg:PasteScript'
assert server_name is None
server_name = self.options.server
else:
server_spec = app_spec
base = os.getcwd()
server = loadserver(server_spec, name=server_name,
relative_to=base)
app = loadapp(app_spec, name=app_name,
relative_to=base)
server(app)
