Subject: [drakma-devel] Problem with pipelined requests
Message-ID: <mux8x9tbs0l.fsf@uzeb.lrde.epita.fr>


       Hello,

I think this question has more to do with Slime, but I'm Cc'ing Drakma
because it might be related. I'm in a situation where
drakma:http-request seems to get stuck as soon as I want to retreive the
BODY of a request. To simplify consider something like this:

(defun foo ()
  (multiple-value-bind
	(body status headers from-uri from-stream must-close reason)
      (http-request ...)
    (values body headers)))

With *header-stream* set to standard output, I can see the transaction
going on until the end, but then the Slime repl doesn't return. I can
type comma and then slime commands, C-c C-c has no effect, and if I type
something in the repl buffer, I get this on the XEmacs minibuffer
window:

; pipelined request... (swank:listener-eval "
")

(note the CR)


On the contrary, if I comment out the (values ...) form in my function,
the request completes and Slime gives me the prompt back.


Any hint on what's going on would be appreciated. And BTW, how do I get
of such a situation in Slime ?


Thanks !

  One additionnal piece of information: if I set :force-binary, the
problem goes away. The server is sending a content type of UTF-8. My
XEmacs (21.4) can't handle UTF-8, but I don't think it's a problem (I
think some displayed characters would be messed up, that's all).

Hi Didier. I've tried you code for google.com - works for me.

It is unlikely from my point of view that the problem is in 
drakma. Looks like slime can't print you values. There are plenty
of ways you can isolate the root of the problem.

Try to save values returned by http-request in variables to
avoid printing them by slime:

(defun foo ()
 (multiple-value-bind
       (body status headers from-uri from-stream must-close reason)
     (http-request "http://google.com")
   (setq b body h headers)
   nil
   ;;(values body headers)
))

Then you may just evaluate b or h and see what happens.
If the printing of srting assigned to b leads to troubles,
you may find problematic part of the string place by printing
only part of string (splitting it to halves or just print it 
char by char)

You also may try you code without slime, running it directly
in you lisp.

Or you can use :force-binary and then save returned array 
to file and then alanyze it.

Regards,
-Anton

Subject: [drakma-devel] faster cl+ssl
Message-ID: <20070707165605.GD14907@ununoctium>

Hi,

the attached patch optimizes the way CL+SSL is used.  It by-passes the
Lisp socket stream and writes directly to the file descriptor (which
helps a lot on some Lisp implementations because CL+SSL's BIO for Lisp
streams appears to have some speed issues).

(However, it needs the very latest release of CL+SSL.)

  I agree. I investigated a little further (dumped the body to a file
etc) and couldn't find any particular character that would cause the
problem in it. However, since then, I discovered that the problem
doesn't occur when I use ACL as the Lisp engine. I normally use SBCL,
which probably has something to do with the problem, then.

I'm also sure that Slime has its part in it in some way. Running the
same code directly in the Lisp engine (either ACL or SBCL BTW) works
fine. On the other hand, running Slime / SBCL within XEmacs (either in
an X frame, or on a tty) makes the problem appear.

I'll continue investigating...

SLIME is very picky about characters it has to show. In my case, I kept
cutting the connection between SLIME and my Lisp image, when encodings
mistmatched (I received latin9 chars while locally I had a utf8 setup).

Quickly,
Pierre

       Hi !

Is it possible to set language preferences in drakma, as ordinary
browsers let you choose from their preference menu ? I guess so, but I
don't know how it work in the protocol, so I thought I'd ask here.

Thanks.

Yes, since you craft custom HTTP request headers.
