[ http://issues.apache.org/jira/browse/MODPYTHON-94?page=comments#action_12358781 ]
Graham Dumpleton commented on MODPYTHON-94: ------------------------------------------- I thought about the ctypes approach when I proposed the first code I referenced. The problem was how you dealt with the complexity of setting up a call which had to refer to data within the internal mod_python request object C structure which wasn't otherwise visible at the Python layer through the mod_python Python request object. Eg. variable_value = ssl_var_lookup( request_object->request_rec->pool, request_object->request_rec->server, request_object->request_rec->connection, request_object->request_rec, variable_name); It may well be possible, but it seemed to me to be quite messy and quite prone to bugs/problems due to the disconnect between the C code and Python code. Ie., you change the C structure to add/change stuff and you have to remember to change any Python code which is somehow using ctypes and defining offsets within the structure. Seemed more trouble that it was worth. > Calling APR optional functions provided by mod_ssl > -------------------------------------------------- > > Key: MODPYTHON-94 > URL: http://issues.apache.org/jira/browse/MODPYTHON-94 > Project: mod_python > Type: New Feature > Components: core > Versions: 3.2 > Environment: Apache 2 > Reporter: Deron Meranda > Attachments: modpython4.tex.patch, requestobject.c.patch > > mod_python is not able to invoke APR Optional Functions. There are > some cases however where this could be of great benifit. > For example, consider writing an authentication or authorization handler > which needs to determine SSL properties (even if to just answer the > simple question: is the connection SSL encrypted). The normal way of > looking in the subprocess_env for SSL_* variables does not work in those > early handler phases because those variables are not set until the fixup > phase. > The mod_ssl module though does provide both a ssl_is_https() and > ssl_var_lookup() optional functions which can be used in earlier > phases. For example look at how mod_rewrite calls those; using > the APR_DECLARE_OPTIONAL_FN and APR_RETRIEVE_OPTIONAL_FN > macros. > I can see how it might be very hard to support optional functions in > general because of the C type linkage issue, but perhaps a select few > could be coded directly into mod_python. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
