"""Wrapper for mod_fcgid, for use as a CherryPy HTTP server when testing.
|
|
|
|
To autostart fcgid, the "apache" executable or script must be
|
|
on your system path, or you must override the global APACHE_PATH.
|
|
On some platforms, "apache" may be called "apachectl", "apache2ctl",
|
|
or "httpd"--create a symlink to them if needed.
|
|
|
|
You'll also need the WSGIServer from flup.servers.
|
|
See http://projects.amor.org/misc/wiki/ModPythonGateway

|
KNOWN BUGS
|
|
==========
|
|
|
|
1. 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.
