Sorry for only replying now, I was away. Let me know if  need to repost my original message.

Yes, see the attached program. I also included a couple of images that fails _most_ of the time.

Uhm, the attached example simply tries to upload a few image files (evaluate the function test-upload).
*Important*: From Linux to XP/Linux all uploads work for both secure and non-secure attempts. From XP
only non-secure uploads work. Secure uploads from XP will work about 5% of the time. I even tried it on
different machines.

No, I removed trivial-ldap completely in the example.

Uploads from
 LispWorks (Win32) to LispWorks or SBCL on Linux fails.

Odd LW error not in SBCL


I'm running a drakma-based app that gives an error on LispWorks, but not
on SBCL.

Error: End of file while reading stream #<FLEXI-STREAMS::FLEXI-BINARY-LATIN-1-IO-STREAM 200ED20F>.

This is after a POST request, and the same error never occurs with SBCL.  Is
there something else I should be setting when calling http-request in LW
versus SBCL?

No, not really.  If SBCL and LispWorks don't behave the same, then I'd
say it's a bug.  Do you have a URL and a way to reproduce this?

END-OF-FILE

Hello list,

I've the following condition

end of file on #<FLEXI-STREAMS::FLEXI-LATIN-1-IO-STREAM {10050A5171}>
   [Condition of type END-OF-FILE]

while trying to do

(drakma:http-request "http://www.bluishcoder.co.nz/atom.xml")

Below is the relevant backtrace part:

  0: (READ-CHAR #<FLEXI-STREAMS::FLEXI-LATIN-1-IO-STREAM {10050A5171}>
T NIL #<unused argument>)
  1: (CHUNGA:READ-LINE* #<FLEXI-STREAMS::FLEXI-LATIN-1-IO-STREAM
{10050A5171}> NIL)
  2: (DRAKMA::READ-STATUS-LINE
#<FLEXI-STREAMS::FLEXI-LATIN-1-IO-STREAM {10050A5171}> NIL)
  3: ((LABELS DRAKMA::FINISH-REQUEST) NIL NIL)
  4: (DRAKMA:HTTP-REQUEST "http://www.bluishcoder.co.nz/atom.xml")

I can access that URI without any problems using my browser. I'm
slightly confused what's going on - could somebody please provide any
comments?

I'm using DRAKMA v. 0.11.1 and SBCL 1.0.13 on x86-64 linux (Ubuntu 7.10).

Best Regards,
Victor.

New release 0.11.2 (Was: CHUNGA:INPUT-CHUNKING-UNEXPECTED-END-OF-FILE)

I could reproduce the example and it seems this is a bug in LispWorks
(which I've reported to LW support).  The new release doesn't really
fix the problem (I can't do that), but it tries to deal with it in a
more or less reasonable way.  Please try it.

Note that the new release is only relevant for LispWorks users.  Users
of other Lisps can as well keep 0.11.1.

Thanks for the report,
Edi.

That does the trick for me.

Re: END-OF-FILE

Thanks Edi -

(let ((chunga:*accept-bogus-eols* t))
	    (drakma:http-request "http://www.bluishcoder.co.nz/atom.xml"))

did the job.

Best Regards,
Vcitor.

Many thanks, Edi. But it appears that you forgot to upload the new version to your site (no, that's
impossible - maybe you just decided to take a break at 3am and did not do it yet :-). Both asdf-install and a
manual download still gives me version 0.11.1 (Just the change log on your site was updated).

Thanks.
Nico

That's strange - I get the new one.  See below.

That's actually a good sign that the new tarball is online.  The
change log is automatically unpacked from the tarball and not uploaded
separately.

But I've just released a new version anyway which "refines" the
previous change a bit.  Again, only relevant for LispWorks users.
