It checks that the :pep:`3333` WSGI spec is properly implemented. It also warns on some common HTTP errors such as non-empty responses for 304 status codes. .. autoclass:: LintMiddleware :copyright: 2007 Pallets :license: BSD-3-Clause ) annotationsN) TracebackType)urlparse)warn)Headers)is_entity_header) FileWrapper) StartResponse)WSGIApplication)WSGIEnvironmentc\rSrSrSrSrg) WSGIWarning!z Warning class for WSGI warnings.N__name__ __module__ __qualname____firstlineno____doc____static_attributes__r[/srv/projetos/modelo_ml_acdoc/venv/lib/python3.13/site-packages/werkzeug/middleware/lint.pyrr!*rrc\rSrSrSrSrg) HTTPWarning%z Warning class for HTTP warnings.rNrrrrrr%rrrc [U5ULa9[U<SUR<S[U5R<S3[SS9 gg)Nz requires z, got . stacklevel)typerrr)contextobjneeds r check_typer()sH Cy kDMM#4F49;M;M:PPQ R  rcF\rSrSrS SjrS SjrS SjrS SjrS SjrSr g) InputStream2cXlgN_streamselfstreams r__init__InputStream.__init__3 rc[U5S:Xa[S[SS9 O[U5S:wa[S[SS9 URR"U6$)NrzWSGI does not guarantee an EOF marker on the input stream, thus making calls to 'wsgi.input.read()' unsafe.
