[issue24291] wsgiref.handlers.SimpleHandler truncates large output blobs
New submission from Jonathan Kamens: The _write method of wsgiref.handlers.SimpleHandler reads as follows: def _write(self,data): self.stdout.write(data) The problem here is that calling write() on a socket is not actually guaranteed to write all of the data in the buffer. If the length of data is large enough, then the kernel will take only part of it. In that case, the rest of the response data will be silently discarded by wsgiref. _write needs to check the return value of self.stdout.write(data), and if it is less than the length of data, repeat the write from the middle of the data buffer, etc., until all the data has been written. -- components: Library (Lib) messages: 244131 nosy: Jonathan Kamens priority: normal severity: normal status: open title: wsgiref.handlers.SimpleHandler truncates large output blobs type: behavior versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4, Python 3.5 ___ Python tracker <http://bugs.python.org/issue24291> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24292] wsgiref.simple_server.WSGIRequestHandler doesn't log request timeouts
New submission from Jonathan Kamens:
http.BaseHTTPRequestHandler logs request timeouts. In handle_one_request():
except socket.timeout as e:
#a read or a write timed out. Discard this connection
self.log_error("Request timed out: %r", e)
self.close_connection = 1
return
Unfortunately, wsgiref.simple_server.WSGIRequestHandler, which overrides
BaseHTTPRequestHandler's handle() method, does _not_ catch and log request
timeouts. Fixing this is a simple matter of wrapping the entire body of its
handle() function in a try with this except clause:
except socket.timeout as e:
self.log_error("Request timed out: %r", e)
raise

[issue26313] ssl.py _load_windows_store_certs fails if windows cert store is empty
New submission from Jonathan Kamens: In ssl.py: def _load_windows_store_certs(self, storename, purpose): certs = bytearray() for cert, encoding, trust in enum_certificates(storename): # CA certs are never PKCS#7 encoded if encoding == "x509_asn": if trust is True or purpose.oid in trust: certs.extend(cert) self.load_verify_locations(cadata=certs) return certs The line right before the return statement will raise an exception if certs is empty. It should be protected with "if certs:" as it is elsewhere in this file. -- components: Windows messages: 259880 nosy: Jonathan Kamens, paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: ssl.py _load_windows_store_certs fails if windows cert store is empty versions: Python 2.7 ___ Python tracker <http://bugs.python.org/issue26313> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
