how to export all files in the directory?

Xu Jingtao — 2011-09-21T09:32:23

Hi www-cl:

I use following codes export my directory in cl-http
=====================================================
(export-url (format nil "http://~A:8000/clouds/" *host-ip*)
            :directory :pathname "/home/www/down/"
            :expiration '(:no-expiration-header)
            :character-set :utf-8
            :recursive-p t :expiration '(:no-expiration-header))
=====================================================
But if file in this directory has no suffix or suffix is not a text file,it could not be read
from web browser.
For example, file name "context" & "context.centos" is bad,and file name "context.txt" is good.

Do anyone know how to fix it to allow all files could be exported in that directory?

With best regards.
jingtao.

simple iframes question

Mark Klein — 2011-09-09T10:04:14

I want to have a PDF document appear within an iframe, so I wrote a cl-http response function that generates the following HTML:

<html>
<body>
<iframe width=1000 height=700 src=http://cci.mit.edu/klein/papers/guidelines.pdf></iframe>
</body>
</html>
The problem is that the PDF document gets downloaded into a new window, and not within the iframe I specified. Any suggestions on what I can do about that?

    Thanks!

Mark

Re: latest (2003) published CL-HTTP 70-190a fails on CMUCL

Chun Tian (binghe — 2011-09-05T01:55:18

That's true. But I should mention that is basically not my work, it's from Madhu's public web site [1] as loadable patch to a relative old CL-HTTP version.

It works on latest Unicode/non-Unicode CMUCL very well, performance is definitely better than SBCL and CCL port from kpoeck's port-template. However, I found there're still some HTTPS-specific issues, but I haven't found time to check if the issue remains in older CL-HTTP if applying the same patch.

Hi,

Chun Tian (binghe) sent us patches in july for a newer version of CMUCL. We haven't added them yet to the original sources.

Karsten Poeck — 2011-09-04T18:53:33

Hello Devon,

I think you will be contacted about getting a newer development version.

There is an old port of Douglas Crosher for cmucl, but the patches 
needed seem to be against a very old version of cl-http.

A bit ago I did a very rough port that allows to start the test-site in 
cmucl (just single-threaded)

Just tested in cmucl 20b on Lion.

To see the demo-site.

1) load ..../contrib/kpoeck/port-template/load.lisp
2) (compile-all)
3) (http::start-examples :load-examples t :host "localhost" :port 8000 
:type :single)

and in your browser:
http://localhost:8000/cl-http/frame.html

Please note that is singe-threaded, so the REPL is blocked until interupted.

I think on x86 there are threads available, will see whether I can get 
them up and running on my mac (lion)

regards

Karsten

Re: latest (2003) published CL-HTTP 70-190a fails on CMUCL

Rainer Joswig — 2011-09-04T12:00:48

Hi,

the weekend here in Germany seems to be one of last this year with better temperatures and some sunshine.

I can give you access to a newer version. The problem is that we have not incorporated patches to support the latest version of CMUCL.
CMUCL has changed a bit during the last years. We should find a solution to that.

The good news is that we have now a new Mac mini hosting the repository and some other stuff. We are still setting things up. We are again using LispWorks to run CL-HTTP on it - thanks to Martin Simmons.

We will also move the mailing list to the new computer.

We should then also put a version of the CL-HTTP sources back online for download.

Regards,

Rainer Joswig

Re: getting a virtual host to listen to post 80

Rainer Joswig — 2011-07-07T21:17:33

I won't really recommend running CL-HTTP as root.

There are two typical solutions:

* run CL-HTTP on some other port, say 8000, and use an external router to map incoming / outgoing traffic on port 80 to the Mac on port 8000. One can configure CL-HTTP to accept these incoming requests as they were coming in port 80. I'm using my home server like this.

* The Mac has a built-in firewall (ipfw) which can redirect ports directly. Same as above, the CL-HTTP listens to port 8000. This times the requests are coming in at port 80, but will be re-routed locally to port 8000. Outgoing answers also need to be re-routed locally.

There are probably more things one could do, like setting up a sandbox...

Regards,

Rainer Joswig

Re: getting a virtual host to listen to post 80

Chun Tian (binghe — 2011-07-07T16:38:43

I don't know how others solve this. I saved LispWorks image as a command-line program (i.e lispworks-6-0-1-cli) and do following steps:

# chown root lispworks-6-0-1-cli
# chmod u+s lispworks-6-0-1-cli

This caused the program being root when starting up, which have access to listen on port 80.  I don't know how to run a Cocoa program in root access on Mac, I guess above method won't work.

I don't think a root Mac OS X program is "more dangerous" then user program, because all of your valuable data are just in your home directory.   If you start a web listener on CL-HTTP and open it to public, then every files in your system could be deleted or transferred to outside because they can use 'system:call-system-showing-output or 'system:call-system to execute any command in your Mac system, but this can be prevented, just like any other Lisp-based production software.

Binghe,

Thanks for the reply! Do you know how I can set Lispworks to run as a root? And is that dangerous from a security perspective (I'm a little out of my depth here).

Re: getting a virtual host to listen to post 80

Chun Tian (binghe — 2011-07-07T15:59:30

Two obvious ideas:

1) CL-HTTP didn't listen on port 80, maybe you should call HTTP:ENABLE-HTTP-SERVICE on both of your ports:

(http:enable-http-service :on-ports '(80 8000))

2) If you're using a Mac, you won't be able to listen on port 80 (< 1024) unless you're running your Lisp as a root (or setuid to root).

getting a virtual host to listen to post 80

Mark Klein — 2011-07-07T15:49:10

I'd like to create a cl-http virtual host that listens to port 80. The virtual host is deliberatorium.mit.edu, which has a DNS entry that aliases to franc2.mit.edu. I added the following code to my server:

(http:add-virtual-host "deliberatorium.mit.edu" 8000)

(http:export-url #u("/" :host "deliberatorium.mit.edu" :port 8000)
            :computed
            :response-function #'(lambda (u s) (declare (ignore u s)) (redirect-to "http://franc2.mit.edu:8000/ci/login")))

That works fine when accessing

http://deliberatorium.mit.edu:8000/

But if I use the following code:

(http:add-virtual-host "deliberatorium.mit.edu" 80)

(http:export-url #u("/index.html" :host "deliberatorium.mit.edu" :port 80)
            :computed
            :response-function #'(lambda (u s) (declare (ignore u s)) (redirect-to "http://franc2.mit.edu:8000/ci/login")))

and try to access 

http://deliberatorium.mit.edu/

then my browser says:

"Safari can’t connect to the server “deliberatorium.mit.edu”

Re: More fixes for SBCL

Martin Simmons — 2011-07-07T10:49:27

I don't know about the other uses of (concatenate 'string ...), but I meant
replace (concatenate (string-type-symbol) ...) by string-append as a start.

Re: More fixes for SBCL

Chun Tian (binghe — 2011-07-07T02:54:01

Hi, Martin

Thank you for your suggestion (and suggestions in other threads in these days). But I found there're many (concatenate 'string ...) forms in CL-HTTP source code (server.lisp, log.lisp, ...). I'm not sure which ones of them should be replaced by (STRING-APPEND ...) instead.

I hope maybe you could find some time checking them and do a full clean up (and let me have the resulting work ...)

Regards,

Chun Tian (binghe)

Re: More fixes for SBCL

Martin Simmons — 2011-07-06T18:16:38

Your change will break it on LispWorks, because (concatenate 'string ...)
might make a base-string even though log-file-name contains non-base
characters.

I think the function string-type-symbol should be removed and all users
changed to call string-append (defined just above string-type-symbol).

More fixes for SBCL

Chun Tian (binghe — 2011-07-06T14:30:04

SBCL's string type is (SIMPLE-ARRAY CHARACTER ...):

* (type-of "xxx")

(SIMPLE-ARRAY CHARACTER (3))

This type, if processed by function 'string-type-symbol, only the part SIMPLE-ARRAY left, which cannot be used as a valid sequence type for 'concatenate.

Attached patch fixed this, this was learnt from kpoeck the first time when I reported SBCL related bug.
