[naviserver-devel] How to set output headers w/o sending content?

[Zoran V. <zv...@ar...>]

Hi!

I'm going thru the module we wrote some times ago which augment
core server commands, and I spotted two of them:

  ns_conn discardcontent
  ns_conn headers status ?type? ?length?"

The first one discards the entire content of the request.
The second one sets required output headers w/o sending 
any content to the remote peer.

Question: is there anything in the server as-is which would
allow me to do this now?

With headers you can pretty much use ns_set
set h [ns_conn outputheaders]
ns_set truncate $h
ns_set put $h Content-Type text/html
...

But there is not way to set status without using one of the ns_return... 
command.

It would be nice to use
ns_conn status for returning current status and
ns_conn status newstatus for setting new status directly

I added the function Ns_ConnSetResponseStatus() for the protocols
stuff, but I didn't add the Tcl equivalent to ns_conn.  I aggree with
Vlad that ns_conn status ?newStatus? would be a good addition (which
requires that we drop connid :-)


Does ns_respond do what you need?

ns_respond ?-status status? ?-type type? \
    { ?-string string? | ?-file filename? | ?-fileid fileid? } \
    ?-length length? ?-headers setid?



What is [ns_conn discardcontent] used for?

The main reason for such mechanism for me is:
I would like to prepare a http response and send it
ultimately to the client (w/o closing the connection
to the client and w/o sending any content bytes).

When the client makes a request to the server, the server
will resond with proper headers and leave the content
handling to me. For this purppose I have made the 
[ns_conn channel] which I can use to handle the content
myself. So it goes this way:

  server accepts a http regular connection
  server formats a proper http response
  server sends the response to client but does not close the connetion
  server gives me the connection socket [ns_conn channel]
  my custom proc takes the socket and does things
  my custom proc closes the socket when finished

So, basically, what I miss in the current implementation
is a way to create and send a proper http request
including headers and status. To set output headers,
there is a way, but to set the proper response status
there isn't.

If I do:

  ns_respond ?-status status? ?-type type? ?-headers setid?

would it do the right thing?
If I have my [ns_conn channel] command (RFE) I'd do:

  set chan [ns_conn channel]
  ns_respond -status 200 -type myown/mimetype
  dothings $chan

The client will get proper http response (ns_respond)
and I will keep the conn socket open (ns_conn channel).
My (dothings) proc will then handle the body
and ultimaltey close the channel, which will then tear
down the socket and the connection to the client.

Look at this example...

On the client-side (this can be another server instance):

  set chan [httpget /some/url/on/server]
  domyprotocol $chan

And on the server (handler for the /some/url/on/server URL)

  set chan [ns_conn channel]
  ns_respond -status 200 -type myown/mimetype
  domyprotocol $chan

The "httpget" on the client is clever. It sends
the requests and processes only up to returned headers.
For the body part, it just returns the comm socket to
the caller. 

The server part accepts a valid http requests, prepares
the proper http response and passes the conn channel to
the caller.

After that, "domyprotocol" on the server and on the client
can do whatever they like on the $chan. This way we have
implemented many services in our product. We only use port
80 and http connection establishment to get a pipe between
peers. Thereafter, we use this pipe for whole lotta things
absolutely unrelated to the http protocol and page-serving 
at all.

Do you follow?

This I have made some years ago and it may not be
needed anymore today (not sure). What I ment with
that is: by processing the incoming request, I 
look into http headers. If I decide to drop the 
request because there is something in the headers
I don't like, I will handle all of the incoming
data from the client and just discard everything.
This is important for keepalive connections because
you have to be careful and read exactly the 
contentLength bytes from the peer. I somehow could
not do that using existing ns_ commands so I invented
my own. Question: is there another way of doing this?
Look at the implementation I have now:


static int
NsxDiscardCmd (cl, interp, objc, objv)
    ClientData      cl;
    Tcl_Interp    * interp;
    int             objc;
    Tcl_Obj       * CONST objv[];
{
    size_t buflen;
    int nb;
    char *buf;
    Ns_Conn *conn;

    /*
     * Syntax: nsx discardcontent
     */

    conn = Ns_TclGetConn(interp);
    if (conn == NULL) {
        Tcl_AppendResult(interp, "no connection", NULL);
        return TCL_ERROR;
    }

    buflen = 32*1024;
    buf = (char*)Tcl_Alloc(buflen);

    /*
     * Sink conn->contentLength bytes from connection
     */

    while(conn->contentLength > 0) {
        nb = (conn->contentLength < buflen) ? conn->contentLength : buflen;
        nb = Ns_ConnRead(conn, buf, nb);
        if (nb == NS_ERROR) {
            break;
        }
        conn->contentLength -= nb;
    }

    Tcl_Free((char*)buf);

    return TCL_OK;
}

Re: [naviserver-devel] How to set output headers w/o sending content?

[Vlad S. <vl...@cr...>]

ns_respond closes the connection, so you cannot use it, still need
ns_conn status newstatus command.

Re: [naviserver-devel] How to set output headers w/o sending content?

[Stephen D. <sd...@gm...>]

I don't think you need this.  In 4.x all content is read fromt the
network and buffered before your code ever runs.  You're just copying
it from one buffer to another.

OK. I did not know that. This command is still there from
the 3.0 in one of my modules. I can just scrap it then.

Drop the connid.=20

   ns_conn status ?newStatus?

is perfectly OK.

Do not forget to update include/ns.h=20

Re: [naviserver-devel] How to set output headers w/o sending content?

[Stephen D. <sd...@gm...>]

The comment for Ns_ConnSetResponseStatus() says that it reurns the
previous status.  It actually returns the current, just-set status. 
So does ns_conn status.

I don't think it's neccessary.  The other simillar functions in that
file have no return value. (Ns_ConnSetUrlEncoding(),
Ns_ConnSetWriteEncodedFlag()...)


Added six weeks ago to AOLserver cvs: Ns_ConnSetStatus(), Ns_ConnGetStatus()

Oops, i was thinking to retern previous status but then change my mind, 
comment left, i will correct it.

Re: [naviserver-devel] How to set output headers w/o sending content?

[Stephen D. <sd...@gm...>]

How about removing the comment, marking the function void, and
changing the naming to match the addtions to AOLserver?

Done except naming, it is different in AS 4.1 CVS and 4.0.x, does it 
really matter much? But i am not insisting.

[Stephen D. <sd...@gm...>]

It looks like the change was added to cvs-HEAD ~6 weeks ago, so this
probably wont find it's way to 4.0.10 at all...

I was just thinking we should keep parity with AOLserver here.  The
new driver code promised for AOLserver might depend upon it and it
might start to get messy when we merge with 4.1 if we have to rename
everything.

Re: [naviserver-devel] How to set output headers w/o sending content?

[Vlad S. <vl...@cr...>]

New driver looks interesting but nothing major different from 4.0 except 
limit pools, and the
driver code/logic looks even more complex. Connection and Sock 
separation is good but still
except dynamic limits i do not see advantages of the new driver, of 
course it is not finished yet but i heard that AOL
is going to start testing 4.1 already, so it looks like 4.1 will have 
what we can see in CVS and something more
flexible for new protocols might be there by the next year only.

I wouldn't wait for them.
