Apache processes Range headers automatically; CherryPy's truncated + output is then truncated again by Apache. See test_core.testRanges. + This was worked around in http://www.cherrypy.org/changeset/1319. +2. Apache does not allow custom HTTP methods like CONNECT as per the spec. + See test_core.testHTTPMethods. +3. Max request header and body settings do not work with Apache. +4. Apache replaces status "reason phrases" automatically. For example, + CherryPy may set "304 Not modified" but Apache will write out + "304 Not Modified" (capital "M"). +5. Apache does not allow custom error codes as per the spec. +6. Apache (or perhaps modpython, or modpython_gateway) unquotes %xx in the + Request-URI too early. +7. mod_python will not read request bodies which use the "chunked" + transfer-coding (it passes REQUEST_CHUNKED_ERROR to ap_setup_client_block + instead of REQUEST_CHUNKED_DECHUNK, see Apache2's http_protocol.c and + mod_python's requestobject.c). +8. Apache will output a "Content-Length: 0" response header even if there's + no response entity body. This isn't really a bug; it just differs from + the CherryPy default. +""" + +import os +curdir = os.path.join(os.getcwd(), os.path.dirname(__file__)) +import re +import time + +from cherrypy.test import helper + + +def read_process(cmd, args=""): + pipein, pipeout = os.popen4("%s %s" % (cmd, args)) + try: + firstline = pipeout.readline() + if (re.search(r"(not recognized|No such file|not found)", firstline, + re.IGNORECASE)): + raise IOError('%s must be on your system path.' % cmd) + output = firstline + pipeout.read() + finally: + pipeout.close() + return output + + +APACHE_PATH = "httpd" +CONF_PATH = "test_mp.conf" + +conf_modpython_gateway = """ +# Apache2 server conf file for testing CherryPy with modpython_gateway. + +ServerName 127.0.0.1 +DocumentRoot "/" +Listen %(port)s +LoadModule python_module modules/mod_python.so + +SetHandler python-program +PythonFixupHandler cherrypy.test.modpy::wsgisetup +PythonOption testmod %(modulename)s +PythonHandler modpython_gateway::handler +PythonOption wsgi.application cherrypy::tree +PythonOption socket_host %(host)s +PythonDebug On +""" + +conf_cpmodpy = """ +# Apache2 server conf file for testing CherryPy with _cpmodpy. + +ServerName 127.0.0.1 +DocumentRoot "/" +Listen %(port)s +LoadModule python_module modules/mod_python.so + +SetHandler python-program +PythonFixupHandler cherrypy.test.modpy::cpmodpysetup +PythonHandler cherrypy._cpmodpy::handler +PythonOption cherrypy.setup cherrypy.test.%(modulename)s::setup_server +PythonOption socket_host %(host)s +PythonDebug On +""" + +class ModPythonSupervisor(helper.Supervisor): + + using_apache = True + using_wsgi = False + template = None + + def __str__(self): + return "ModPython Server on %s:%s" % (self.host, self.port) + + def start(self, modulename): + mpconf = CONF_PATH + if not os.path.isabs(mpconf): + mpconf = os.path.join(curdir, mpconf) + + f = open(mpconf, 'wb') + try: + f.write(self.template % + {'port': self.port, 'modulename': modulename, + 'host': self.host}) + finally: + f.close() + + result = read_process(APACHE_PATH, "-k start -f %s" % mpconf) + if result: + print(result) + + def stop(self): + """Gracefully shutdown a server that is serving forever.""" + read_process(APACHE_PATH, "-k stop") + + +loaded = False +def wsgisetup(req): + global loaded + if not loaded: + loaded = True + options = req.get_options() + + import cherrypy + cherrypy.config.update({ + "log.error_file": os.path.join(curdir, "test.log"), + "environment": "test_suite", + "server.socket_host": options['socket_host'], + }) + + modname = options['testmod'] + mod = __import__(modname, globals(), locals(), ['']) + mod.setup_server() + + cherrypy.server.unsubscribe() + cherrypy.engine.start() + from mod_python import apache + return apache.OK + + +def cpmodpysetup(req): + global loaded + if not loaded: + loaded = True + options = req.get_options() + + import cherrypy + cherrypy.config.update({ + "log.error_file": os.path.join(curdir, "test.log"), + "environment": "test_suite", + "server.socket_host": options['socket_host'], + }) + from mod_python import apache + return apache.OK + |
