PyPI XMLRPC interface no longer works with Python 2.6

I just tried the documented interfaces for PyPI (https://wiki.python.org/moin/PyPIXmlRpc) with Python 2.6 and it fails with an error:

...

python pypirpc.py Traceback (most recent call last): File "pypirpc.py", line 7, in <module> pprint.pprint(client.package_releases('egenix-web-installer-test')) File "/usr/local/python-2.6-ucs2/lib/python2.6/xmlrpclib.py", line 1199, in __call__ return self.__send(self.__name, args) File "/usr/local/python-2.6-ucs2/lib/python2.6/xmlrpclib.py", line 1489, in __request verbose=self.__verbose File "/usr/local/python-2.6-ucs2/lib/python2.6/xmlrpclib.py", line 1253, in request return self._parse_response(h.getfile(), sock) File "/usr/local/python-2.6-ucs2/lib/python2.6/xmlrpclib.py", line 1390, in _parse_response p.close() File "/usr/local/python-2.6-ucs2/lib/python2.6/xmlrpclib.py", line 604, in close self._parser.Parse("", 1) # end of data xml.parsers.expat.ExpatError: no element found: line 1, column 0

The call works with Python 2.7. It appears that xmlrpclib is not receiving any body data from the server. The returned data in 2.7 looks completely harmless: send: "POST /pypi HTTP/1.1\r\nHost: pypi.python.org\r\nAccept-Encoding: gzip\r\nUser-Agent: xmlrpclib.py/1.0.1 (by www.pythonware.com)\r\nContent-Type: text/xml\r\nContent-Length: 185\r\n\r\n<?xml version='1.0'?>\n<methodCall>\n<methodName>package_releases</methodName>\n<params>\n<param>\n<value><string>egenix-web-installer-test</string></value>\n</param>\n</params>\n</methodCall>\n" reply: 'HTTP/1.1 200 OK\r\n' header: Server: nginx/1.6.0 header: Content-Type: text/xml header: charset: UTF-8 header: Strict-Transport-Security: max-age=31536000; includeSubDomains header: Transfer-Encoding: chunked header: Accept-Ranges: bytes header: Date: Tue, 08 Jul 2014 14:19:41 GMT header: Via: 1.1 varnish header: Connection: keep-alive header: X-Served-By: cache-fra1229-FRA header: X-Cache: MISS header: X-Cache-Hits: 0 header: X-Timer: S1404829181.210045,VS0,VE325 body: "<?xml version='1.0'?>\n<methodResponse>\n<params>\n<param>\n<value><array><data>\n<value><string>0.2.0</string></value>\n</data></array></value>\n</param>\n</params>\n</methodResponse>\n" Could this be a network error rather than a program one ? The code in 2.7 does a retry in case of a connection reset or abort, which code in 2.6 and earlier does not apply.

Ah, sorry. You're right. I had looked at a diff of the module between 2.6 and 2.7 and saw lots of HTTPS related changes. With https:// it does work in 2.6 as well. Thanks. I'll close the bug report a fix the wiki page.

Oh Good. I thought I was going crazy there for a minute :) I’m pretty sure it happens because of the redirect from HTTP to HTTPS. On Jul 8, 2014, at 11:17 AM, M.-A. Lemburg wrote:

Uh what? HTTPS works fine on my copy of 2.6? If I recall this problem only happens if you use http:// on 2.6.

Ah, sorry. You're right. I had looked at a diff of the module between 2.6 and 2.7 and saw lots of HTTPS related changes.

With https:// it does work in 2.6 as well.

Thanks. I'll close the bug report a fix the wiki page.

Yes. xmlrpclib in Python 2.6 doesn't understand HTTPS. Support for it was added in Python 2.7.

I just tried the documented interfaces for PyPI (https://wiki.python.org/moin/PyPIXmlRpc) with Python 2.6 and it fails with an error:

The call works with Python 2.7. It appears that xmlrpclib is not receiving any body data from the server.

The returned data in 2.7 looks completely harmless:

send: "POST /pypi HTTP/1.1\r\nHost: pypi.python.org\r\nAccept-Encoding: gzip\r\nUser-Agent: xmlrpclib.py/1.0.1 (by www.pythonware.com)\r\nContent-Type: text/xml\r\nContent-Length: 185\r\n\r\n<?xml version='1.0'?>\n<methodCall>\n<methodName>package_releases</methodName>\n<params>\n<param>\n<value><string>egenix-web-installer-test</string></value>\n</param>\n</params>\n</methodCall>\n" reply: 'HTTP/1.1 200 OK\r\n' header: Server: nginx/1.6.0 header: Content-Type: text/xml header: charset: UTF-8 header: Strict-Transport-Security: max-age=31536000; includeSubDomains header: Transfer-Encoding: chunked header: Accept-Ranges: bytes header: Date: Tue, 08 Jul 2014 14:19:41 GMT header: Via: 1.1 varnish header: Connection: keep-alive header: X-Served-By: cache-fra1229-FRA header: X-Cache: MISS header: X-Cache-Hits: 0 header: X-Timer: S1404829181.210045,VS0,VE325 body: "<?xml version='1.0'?>\n<methodResponse>\n<params>\n<param>\n<value><array><data>\n<value><string>0.2.0</string></value>\n</data></array></value>\n</param>\n</params>\n</methodResponse>\n"

Could this be a network error rather than a program one ?

The code in 2.7 does a retry in case of a connection reset or abort, which code in 2.6 and earlier does not apply.

Thanks,

That's probably the cause, even though I don't get a redirect header in the XMLRPC reply. The server appears to return a simple HTTP/1.1 200 OK and then stops talking to Python 2.6. Here's a telnet transcript:

...

telnet pypi.python.org 80 Trying 185.31.17.175... Connected to pypi.python.org. Escape character is '^]'. POST /pypi HTTP/1.0 Host: pypi.python.org User-Agent: xmlrpclib.py/1.0.1 (by www.pythonware.com) Content-Type: text/xml Content-Length: 185

...

I guess the HTTP/1.0 in the POST request causes Varnish to close the connection without a redirect. A bit weird. Python 2.7 sends an HTTP/1.1.

Looks like closing the ticket has to be done by someone else.
