I'm afraid this is still not clear to me, but I'll have
to give you some examples why this is making me trouble.
I will prepare the switch to naviserver in our development
branch in couple of days and then this will be clear

I would like to see what Stephen thinks about this as well.
He wanted some code to look at and I've made the patch 
available on SF. Hopefully he will have some time to
review it and tell what he thinks.

Oh yes... this is what I'm afraid of! Therefore, I'd have
to make the switch first so I can see what is sill lurking
in the modified version of AS I have but forgot to clearly
comment...

On the top of my head:

  o. binder listening on all interfaces
  o. watchdog process
  o. maybe a couple of tiny things which I have yet to find out
     when I switch (still didn't switch but this is another story)

I would also like to extract some functionality from our toolkit. It would be 
nice if there is a small toolkit with basic stuff like database abstraction, 
page and session management, authentication and basic permissions.
I like the idea to rewrite it in a way so that it utilizes new naviserver 
functions like the c-cookie-api or database stuff (I read from Stephen?).
In our framework we do not map and use the standard ADP-stuff, we use 
registered filters and procs and ns_adp_parse files, but it should be 
managable to rewrite it.

What do you think about a "contrib" directory (like in PostgreSQL or other 
packages):

<QUOTE>

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly because
they address a limited audience or are too experimental to be part of
the main source tree.  This does not preclude their usefulness.

Each subdirectory contains a README file with information about the
module.

</QUOTE>

Something similar. This way it would be clearly stated that something is 
useful and/or experimental and/or just new (Message: "Give it a try").

Maybe this would be a place for a chroot-installation-script, like my first 
try here:
http://www.kinetiqa.de/aolserver/
(But rewritten, it's a little bit old and worries about too many packages)

I have light-weight templating i can extract and put into modules/tcl,
that will be one small file and will support OACS-style templating
where .adp and .tcl are define template. But it requires some work to be 
extracted
from my "big" framework system.

For public version  in the future i would include as manu maintained 
modules as possible.

[naviserver-devel] nslog.c problem

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

In nslog.c:

    /* Get parameters from configuration file */
    logPtr->rollfmt = Ns_ConfigGetValue(path,"rollfmt");
    if (logPtr->rollfmt == NULL) {
        logPtr->rollfmt = ns_strdup(logPtr->rollfmt);
    }

This is not what the writer wanted, or? 
I assume it should have been written as:

    /* Get parameters from configuration file */
    logPtr->rollfmt = Ns_ConfigGetValue(path,"rollfmt");
    if (logPtr->rollfmt != NULL) {
        logPtr->rollfmt = ns_strdup(logPtr->rollfmt);
    }

I will fix this in head.

I don't, yet. My primary goal is to get to a point where we can
switch to naviserver internally. I'm still not there, so for me
there is more work to do.

I have no idea. We are using the server with our own templating 
framework based on tDOM but I do not think this is something 
of general interest.

We use only our own modules. But, generally speaking, a couple
of database drivers should be there (postgres, ... ?)

I'm already working on this. I'd opt to use Tcl doctools. It allows to
write good Tcl/C docs in a very simple POD-like format and it produces
nroff, html and wiki output (among others).  In some weeks I will have
a complete set of everything needed to start filling in content. There is
already content on AOL site and some on the wiki. It should be easy to 
cut/paste from there after the frwamework has been setup.

[naviserver-devel] Roadmap

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

Hi guys,

Do you have any roadmap-kind of plans or thoughts about naviserver?
Slowly it is getting to the point when it can replace all my patched 
aolservers, i already use it at home instead of AS. As i remember, the 
initial goal was to patch AS with all out modifications so we start 
using it instead of AS and then decide what to do next, right?

So,


1. Do you have any thoughts about Web tools/frameworks we can bundle 
with it?
2. Which modules should be in the distrib?
3. Docs are still needed to be addressed, when i do not have strength to 
develop late evenings i could write/add docs but which format we gonna use?
4. Do we need to refine installation procedure?
After installation, going to port 8080 (this way no need root to install 
and test it) the user should see some kind of web page with at least 
stats and docs (similar to apache, that is the big hole in AS right now)

Re: [naviserver-devel] ns_sha1 command

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

Yes, ns_sha1 or ns_md5 are doing the same task, it is just sha1 is 
freely availabe module and somehow got into AS instead of MD5.
But etiher one or both in the core would be good to have.

I have no problem with adding such command.
I'm not the crypto expert so you must maybe help me understand...

So,

  set hash [ns_sha1 my_secret_string]

gives me the hash value

But, I can imagine:

  set hash [ns_md5 my_secret_string]

to be of the same functionality, or?

So, what I'd maybe do is:

  set hash [ns_hash sha1 my_string]
  set hash [ns_hash md5 my_string]

or something similar. 

We have made the md5 hash extension for us already.
I have it in one of the numerous modules we have
written for AS. I can imagine we can invent a 
wrapper command which would server as a central hashing
repository.

Hi guys,

So what is the final word about adding ns_sha1 in the core?
I would really like to add it and eliminate additional requirement for 
naviserver installation for third party module.

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

Drop the connid.=20

   ns_conn status ?newStatus?

is perfectly OK.

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?

> What is [ns_conn discardcontent] used for?

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?

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

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?

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

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

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

[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?

Oh yeah, the zero is free.  That should do it.

Suggestion: we should try spearate these two steps: reformatting
and actual code changes.

I quite often merge these two in one, which makes the real changes
pretty obscure. But this is really wrong. One should first cleanup
then commit with the log clearly stated that no functional code 
changes have been done. Then one should go and add real changes,
of course by trying to follow the style guidelines. The latter are
quite obvious when skimming thru the rest of the code and eventually
the Tcl code (both styles are very similar). 

And, yes. I would also preffer to make an RFE or bug report in SF
before doing the change. This is for the sole purpose of trails 
and documentation. Otherwise, we will get lost very soon.

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

I've been using that new module for so long time that i did not realized 
that the code is so different than
current style, i am sorry.

No, i did not add anythig new,  X-Forwarded-For was handled by old nslog 
as well,
i just restructure the module to support more options

nslog used to have index.html, in the CVS i do not see it, so i put the 
docs in the nslog.c for now and
we do not have docs for modules yet.

Yes, that's my fault, i will change it to follow naviserver code style.
