--- Begin Message ---Package: python-webdav Version: 0.9.8-3 Severity: normal Dear Maintainer, pywebdav uses persistent connections even for HTTP/1.0 GET requests without a Connection: Keep-Alive header. This causes the client to hang waiting for the connection to close. RFC2616 explicitly states HTTP/1.1 servers must not assume HTTP/1.0 clients to support persistent connections: === Begin RFC2616 excerpt === 8.1.2.1 Negotiation [...] Clients and servers SHOULD NOT assume that a persistent connection is maintained for HTTP versions less than 1.1 unless it is explicitly signaled. [...] === End RFC2616 excerpt === In addition, both a Connection: close and a Connection: Keep-Alive header are sent and Date is sent twice: === Begin tcpflow dump === 127.000.000.001.50660-127.000.000.001.08009: GET / HTTP/1.0 User-Agent: w3m/0.5.3+cvs-1.1055 Accept: text/html, text/*;q=0.5, image/*, */* Accept-Encoding: Xgzip, compress, bzip, bzip2, deflate Accept-Language: en;q=1.0 Host: localhost:8009 Pragma: no-cache Cache-control: no-cache 127.000.000.001.08009-127.000.000.001.50660: HTTP/1.0 200 OK 127.000.000.001.08009-127.000.000.001.50660: Server: DAV/0.9.8 Python/2.7.3 127.000.000.001.08009-127.000.000.001.50660: Date: Sat, 01 Jun 2013 10:11:00 GMT 127.000.000.001.08009-127.000.000.001.50660: Connection: close 127.000.000.001.08009-127.000.000.001.50660: Accept-Ranges: bytes 127.000.000.001.08009-127.000.000.001.50660: Date: Sat, 01 Jun 2013 10:11:00 GMT 127.000.000.001.08009-127.000.000.001.50660: DAV: 1 127.000.000.001.08009-127.000.000.001.50660: Last-Modified: Sat, 01 Jun 2013 10:11:00 GMT 127.000.000.001.08009-127.000.000.001.50660: Connection: Keep-Alive 127.000.000.001.08009-127.000.000.001.50660: Keep-Alive: timeout=15, max=86 127.000.000.001.08009-127.000.000.001.50660: Content-Length: 253 127.000.000.001.08009-127.000.000.001.50660: Content-Type: text/html; charset=utf-8 127.000.000.001.08009-127.000.000.001.50660: 127.000.000.001.08009-127.000.000.001.50660: <html> <head><title>Journal listing</title></head> <body> <table> <tr><th>Name</th></tr> <tr><td><a href="by-id/">by-id/</a></td></tr> <tr><td><a href="by-tags/">by-tags/</a></td></tr> <tr><td><a href="by-title/">by-title/</a></td></tr> </table> </html> === End tcpflow dump === A quick patch for these issues: === Begin === --- WebDAVServer.py.old 2013-06-01 14:23:19.105319133 +0200 +++ WebDAVServer.py 2013-06-01 14:23:35.457092427 +0200 @@ -62,9 +62,9 @@ log.debug("Use send_body method") self.send_response(code, message=msg) - self.send_header("Connection", "close") + if 'Connection' not in headers: + self.send_header("Connection", "close") self.send_header("Accept-Ranges", "bytes") - self.send_header('Date', rfc1123_date()) self._send_dav_version() @@ -255,8 +255,9 @@ self.send_body(data, status_code, None, None, content_type, headers) else: - headers['Keep-Alive'] = 'timeout=15, max=86' - headers['Connection'] = 'Keep-Alive' + if self.request_version == 'HTTP/1.1': + headers['Keep-Alive'] = 'timeout=15, max=86' + headers['Connection'] = 'Keep-Alive' self.send_body_chunks_if_http11(data, status_code, None, None, content_type, headers) === End === -- System Information: Debian Release: 7.0 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'testing'), (500, 'stable'), (100, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.8-trunk-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages python-webdav depends on: ii python 2.7.3-4 ii python-pkg-resources 0.6.24-1 python-webdav recommends no packages. python-webdav suggests no packages. -- no debconf information
