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). iÿÿÿÿN(tDictTypet StringTypet TupleTypetListTypes^[a-zA-Z][a-zA-Z0-9\-_]*$s [\000-\037]t WSGIWarningcBseZdZRS(s: Raised in response to WSGI-spec-related warnings (t__name__t __module__t__doc__(((s0/usr/lib/python2.6/site-packages/webtest/lint.pyRxscs‡fd†}|S(s® When applied between a WSGI server and a WSGI application, this middleware will check for WSGI compliancy on a number of levels. This middleware does not modify the request or response in any way, but will throw an AssertionError if anything seems off (except for a failure to close the application iterator, which will be printed to stderr -- there's no way to throw an exception at that point). cs||\}‰t|ƒg‰‡‡fd†}t|dƒ|deZd„Zd„Zd„Zd„Zd„Zd„ZRS(cCs ||_dS(N(tinput(tselft wsgi_input((s0/usr/lib/python2.6/site-packages/webtest/lint.pyt__init__¶scGs|ii|Œ}|S(N(R#tread(R$Rtv((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR'¹scGs|ii|Œ}|S(N(R#treadline(R$RR(((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR)¿scGs'|ii|Œ}x|D]}qW|S(N(R#t readlines(R$Rtlinestline((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR*Äs ccs'x |iƒ}|pdS|VqdS(N(R)(R$R,((s0/usr/lib/python2.6/site-packages/webtest/lint.pyt__iter__Ìs  cCsdS(N((R$((s0/usr/lib/python2.6/site-packages/webtest/lint.pytcloseÓs(RRR&R'R)R*R-R.(((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR´s      RcBs5eZd„Zd„Zd„Zd„Zd„ZRS(cCs ||_dS(N(terrors(R$t wsgi_errors((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR&ØscCs|ii|ƒdS(N(R/twrite(R$ts((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR1ÛscCs|iiƒdS(N(R/tflush(R$((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR3ßscCs"x|D]}|i|ƒqWdS(N(R1(R$tseqR,((s0/usr/lib/python2.6/site-packages/webtest/lint.pyt writelinesâscCsdS(N((R$((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR.æs(RRR&R1R3R5R.(((s0/usr/lib/python2.6/site-packages/webtest/lint.pyRÖs     RcBseZd„Zd„ZRS(cCs ||_dS(N(twriter(R$t wsgi_writer((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR&ëscCs|i|ƒdS(N(R6(R$R2((s0/usr/lib/python2.6/site-packages/webtest/lint.pyt__call__îs(RRR&R8(((s0/usr/lib/python2.6/site-packages/webtest/lint.pyRés tPartialIteratorWrappercBseZd„Zd„ZRS(cCs ||_dS(N(R(R$t wsgi_iterator((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR&ôscCs t|iƒS(N(RR(R$((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR-÷s(RRR&R-(((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR9òs RcBs5eZd„Zd„Zd„Zd„Zd„ZRS(cCs.||_t|ƒ|_t|_||_dS(N(toriginal_iteratortiterRtFalsetclosedtcheck_start_response(R$R:R?((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR&ýs  cCs|S(N((R$((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR-scCs0|iiƒ}|idj o d|_n|S(N(RtnextR?R (R$R(((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR@s cCs1t|_t|idƒo|iiƒndS(NR.(tTrueR>thasattrR;R.(R$((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR.s cCs"|iptiidƒndS(Ns/Iterator garbage collected without being closed(R>tsyststderrR1(R$((s0/usr/lib/python2.6/site-packages/webtest/lint.pyt__del__s   (RRR&R-R@R.RE(((s0/usr/lib/python2.6/site-packages/webtest/lint.pyRûs    cCsx)ddddddddd g D]}q"Wxd d gD]}q9Wd |jotid tƒnx(|iƒD]}d|joqqqqqqWt|dƒt|dƒ|ddjotid|dtƒn|idƒon|idƒpndS(NtREQUEST_METHODt SERVER_NAMEt SERVER_PORTs wsgi.versions wsgi.inputs wsgi.errorsswsgi.multithreadswsgi.multiprocesss wsgi.run_oncetHTTP_CONTENT_TYPEtHTTP_CONTENT_LENGTHt QUERY_STRINGs’QUERY_STRING is not in the WSGI environment; the cgi module will use sys.argv when this variable is missing, so application errors are more likelyt.tGETtHEADtPOSTtOPTIONStPUTtDELETEtTRACEsUnknown REQUEST_METHOD: %rtCONTENT_LENGTHt SCRIPT_NAME(RMRNRORPRQRRRS(twarningstwarnRtkeyst check_inputt check_errorstget(Rtkey((s0/usr/lib/python2.6/site-packages/webtest/lint.pyRs<           cCs!xddddgD]}qWdS(NR'R)R*R-((R%tattr((s0/usr/lib/python2.6/site-packages/webtest/lint.pyRY]scCsxdddgD]}qWdS(NR3R1R5((R0R]((s0/usr/lib/python2.6/site-packages/webtest/lint.pyRZcscCsb|iddƒd}t|ƒ}t|ƒdjp|ddjotid|tƒndS(Niiiit sjThe status string (%r) should be a three-digit integer followed by a single space and a status explanation(tsplitR tintRRVRWR(Rt status_codet status_int((s0/usr/lib/python2.6/site-packages/webtest/lint.pyR is  $cCs7h}x*|D]"}|\}}d||iƒns0  "  7"  !
