Re: Problem with SBCL, Drakma, and quicklisp

Patrick May — 2013-03-23T21:35:23

Thanks to Stas Boukarev and Dave Cooper, I'm back up and running with ccl.  I've raised the problem on the sbcl list and will keep trying to find an answer.

Thank you for the quick responses.

Regards,

Patrick

Pierre,

I don't know whether this is a problem with your sbcl installation, but it
certainly does not look like a Drakma problem to me.

First, I would make sure that I'm using the latest quicklisp, using
(ql:update-client) and (ql:update-all-dists).  If that didn't help, I'd
upgrade to the latest SBCL release.  If that did not help either, I'd ask
again :)

Cheers,
Hans

Thanks for the quick response.  I removed ~/.cache/common-lisp, started SBCL and tried to load Drakma.  I got this error:

I have just tried this

(drakma:HTTP-REQUEST "
http://ichart.yahoo.com/table.csv?s=IBM&a=0&b=01&c=2012&d=11&e=31&f=2012&g=d&ignore=.csv
")

with Drakma from current Quicklisp and it works.  I guess that you have
.fasl files of old versions somewhere.  Try removing ~/.cache/common-lisp/
and maybe fetch Quicklisp again.

Problem with SBCL, Drakma, and quicklisp

Patrick May — 2013-03-23T14:03:38

Any idea what could be causing this?  I've attached the backtrace in case that helps.

Peter,

thanks for the bug report.  I fixed the problem (
https://github.com/edicl/drakma/commit/1973b62d969b886fc536d4ebd44cfe570308c998)
and released a new version of DRAKMA.

Re: Error while trying to POST some JSON data

Hans Hübner — 2013-03-22T16:21:26

Drakma's behavior with respect to redirects has recently changed so that it
is standard compliant.  I would like to keep it that way, but if this is a
hurdle that can't be worked around, I am open to suggestions to change it
again.

Re: Error while trying to POST some JSON data

2013-03-22T16:55:55

How is the site redirecting? What's the HTTP status code they use?


Depending on the status code, that's actually valid behaviour.

Re: Error while trying to POST some JSON data

Peter Stirling — 2013-03-22T12:57:15

I was getting this error too, I reverted to the previous version of 
cl+ssl in quicklisp by putting it in the local-projects directory.

I've been meaning to report another problem I've had with the new 
version of drakma, it seems that when I POST login details to a site 
that I'm using it replies with a redirect, and then drakma tries to POST 
the login details to the redirected page rather than accessing it with a 
GET. I'll try and make a test case sometime this weekend.

Re: Error while trying to POST some JSON data

Kevin Raison — 2013-03-21T21:44:42

I encountered this same error after upgrading packages via quicklisp.  I
rolled back cl+ssl to version cl+ssl-20130128-git and the problem went
away.  I have not had time to investigate further yet.

Kevin,

Thank you very much - I was absolutely sure I was doing something wrong!

Could you please show how I can roll back to cl+ssl-20130128-git ? I don't
know how to do it, I'm a quicklisp newbie.

Many thanks,

Error while trying to POST some JSON data

I'm trying to POST some JSON data to a web service:

Re: error while parsing set cookie containing httponly & secure

Hans Hübner — 2013-01-07T06:48:27


Currently, there is no function to enable logging of request bodies.  If
what you're interested in is seeing how post parameters are encoded, you
can trace DRAKMA::ALIST-TO-URL-ENCODED-STRING at this time.

Re: error while parsing set cookie containing httponly & secure

Simon Koch — 2013-01-06T21:42:30

I updated the library and it seems to work, thank you for the fix.

Is there any possibility to also show the post data send, when printing
the sent header on standard-out via (setf drakma:*header-stream*
*standard-output*)? Currently only the "normal" headers are shown, without
the post-data part.

Greetings,

Simon

I fixed this in Chunga, the new release is 1.1.2.  If you could give

Drakma documentation overhaul

Hans Hübner — 2012-12-09T21:04:32

Hi,

while fixing some bugs in Drakma recently, I was notified that the
documentation and the docstrings were not matching well anymore.  I
have decided to overhaul the documentation, and in the process of
that, I also made some source changes.

There will be more changes soon, so you may experience instabilities
when you're using the master branch from github.

Comments regarding the documentation would be very welcome, I have put
a version up for review at http://netzhansa.com/drakma.html

Thanks,
Hans

I did: https://github.com/edicl/drakma/issues/24

I also got a crude fix for the problem by adding those two functions:

(defun clean-string (string of)
  "cleans a given string of of by exploding them and concatenating the
resulting list using consing"
  (labels ((clean (sequence)
     (if sequence
 (if (char= (car sequence) of)
     (clean (cdr sequence))
     (cons (car sequence)
   (clean (cdr sequence))))
 nil)))
    (coerce (clean (coerce string 'list)) 'string)))

(defun fix-parameters (parameters)
  "goes through the given parameterlist an checks whether seperated
parameters are in one parameterpair cons
   for then seperating them and cleaning them of #\; and #\SPACE"
  (if parameters

Simon,

thank you for your report.  It is not a known problem.  I'd be
grateful if you could open a github issue
(https://github.com/edicl/drakma/issues).  From glancing at your
description, it seems to me that this is indeed a bug that should be
fixed.
