Some of the things this checks: * Signature of the application and start_response (including that keyword arguments are not used). * Environment checks: - Environment is a dictionary (and not a subclass). - That all the required keys are in the environment: REQUEST_METHOD, SERVER_NAME, SERVER_PORT, wsgi.version, wsgi.input, wsgi.errors, wsgi.multithread, wsgi.multiprocess, wsgi.run_once - That HTTP_CONTENT_TYPE and HTTP_CONTENT_LENGTH are not in the environment (these headers should appear as CONTENT_LENGTH and CONTENT_TYPE). - Warns if QUERY_STRING is missing, as the cgi module acts unpredictably in that case. - That CGI-style variables (that don't contain a .) have (non-unicode) string values - That wsgi.version is a tuple - That wsgi.url_scheme is 'http' or 'https' (@@: is this too restrictive?) - Warns if the REQUEST_METHOD is not known (@@: probably too restrictive). - That SCRIPT_NAME and PATH_INFO are empty or start with / - That at least one of SCRIPT_NAME or PATH_INFO are set. - That CONTENT_LENGTH is a positive integer. - That SCRIPT_NAME is not '/' (it should be '', and PATH_INFO should be '/'). - That wsgi.input has the methods read, readline, readlines, and __iter__ - That wsgi.errors has the methods flush, write, writelines * The status is a string, contains a space, starts with an integer, and that integer is in range (> 100). * That the headers is a list (not a subclass, not another kind of sequence). * That the items of the headers are tuples of strings. * That there is no 'status' header (that is used in CGI, but not in WSGI). * That the headers don't contain newlines or colons, end in _ or -, or contain characters codes below 037. * That Content-Type is given if there is content (CGI often has a default content type, but WSGI does not). * That no Content-Type is given when there is no content (@@: is this too restrictive?) * That the exc_info argument to start_response is a tuple or None. * That all calls to the writer are with strings, and no other methods on the writer are accessed. * That wsgi.input is used properly: - .read() is called with zero or one argument - That it returns a string - That readline, readlines, and __iter__ return strings - That .close() is not called - No other methods are provided * That wsgi.errors is used properly: - .write() and .writelines() is called with a string - That .close() is not called, and no other methods are provided. * The response iterator: - That it is not a string (it should be a list of a single string; a string will work, but perform horribly). - That .next() returns a string - That the iterator is not iterated over until start_response has been called (that can signal either a server or application error). - That .close() is called (doesn't raise exception, only prints to sys.stderr, because we only know it isn't called when the object is garbage collected). iN(tDictTypet StringTypet TupleTypetListTypes^[a-zA-Z][a-zA-Z0-9\-_]*$s [\000-\037]t WSGIWarningcBseZdZRS(s: Raised in response to WSGI-spec-related warnings (t__name__t __module__t__doc__(((s;/opt/alt/python27/lib/python2.7/site-packages/paste/lint.pyRxscsfd}|S(s When applied between a WSGI server and a WSGI application, this middleware will check for WSGI compliancy on a number of levels.
