Hi, Anyone using the python client. I used it before, I think it was with 7.9, where it was still working. But now on a recent snapshot I cannot get my example to work anymore. I will report to maintainer but I would like to know if anyone could confirm having difficulties too. Anything changed in the protocol? I'm running on Python 2.7.8 :: Anaconda 2.0.1 (x86_64), on Mac that is. The error message occurs when trying to set up a session: /Users/marcvangrootel/Dropbox/notebooks/BaseXClient.py in __init__(self, host, port, user, password, receive_bytes_encoding, send_bytes_encoding) 129 # evaluate success flag 130 if not self.server_response_success(): --> 131 raise IOError('Access Denied.') 132 133 def execute(self, com): IOError: Access Denied. Thanks, --Marc

Hi Andreas, Maybe that is a better way but I am using the client from within a IPython Notebook which means I can integrate a bit more closely with the notebook interface and do queries and graphing with the data using IPythons great analytics and graphing features.. I had this working with 7.9. --Marc On Mon, Dec 29, 2014 at 2:45 PM, Andreas Jung <lists@zopyx.com> wrote:

Hi Dirk, I fooled around with the client a bit but I am not familiar enough with the crypto stuff. As Christian mentioned it might be trivial I took a stab at it. However I am a bit stumped on the use of sha256 vs. md5, the docs [1] mentions: {md5(md5(username:realm:password) + nonce)} but Christian's mail mentioned salted sha256. How's one related to the other? Second issue I have is regarding the salt. Where do I put it and do I then have to add it to all server communication or only to the authentication/getting a session? I could take another stab but I guess I need a little bit of guidance. Sorry if I sound like a noob on this crypto stuff ;-) [1]: http://docs.basex.org/wiki/Server_Protocol#Authentication On Mon, Dec 29, 2014 at 2:54 PM, Marc van Grootel <marc.van.grootel@gmail.com> wrote:

Yesss. I think I have it. The salt and sha256 bit threw me off a bit but after a look at the java code it was indeed trivial. I do some more testing with it and also make it work with 7.x and then I submit it to the maintainer. Thanks for playing rubber duck. --Marc On Mon, Dec 29, 2014 at 5:05 PM, Marc van Grootel <marc.van.grootel@gmail.com> wrote:

Hi, Seems to work fine. At least, I didn't introduce any issues that weren't already there. I didn't find the email address of the maintainer I attach the file to this post. I have checked on recent snapshot of 8.0 and 7.9. If you want me to submit it differently or have me create a pull request let me know. Here's the diff 120c120 < timestamp = self.recv_c_str() ---
response = self.recv_c_str().split(':')
124,126c124,133 < #FIXME: should we allow to customize password encoding? < hfun.update(hashlib.md5(password.encode('us-ascii')).hexdigest().encode('us-ascii')) < hfun.update(timestamp.encode('us-ascii')) ---
if len(response) > 1: code = "%s:%s:%s" % (user,response[0],password) nonce = response[1] else: code = password nonce = response[0]
hfun.update(hashlib.md5(code.encode('us-ascii')).hexdigest().encode('us-ascii')) hfun.update(nonce.encode('us-ascii'))

Thanks Marc, I have patched the python code, it should now be compatible with BaseX 8.0. Christian On Mon, Dec 29, 2014 at 5:35 PM, Marc van Grootel <marc.van.grootel@gmail.com> wrote:

Hello Marc, indeed, there has been changes regarding the authentication in our client/server protocol as outlined by Christian in this mail: https://mailman.uni-konstanz.de/pipermail/basex-talk/2014-December/007832.ht.... There is also some short documentation to be found here: http://docs.basex.org/wiki/Server_Protocol Hence, the client bindings have to be changed accordingly. It should be a fairly trivial change. If anyone wants to submit a short patch for the python clients (or others clients we support), I am sure it would be appreciated. Cheers, Dirk On 12/29/2014 02:40 PM, Marc van Grootel wrote:
