Hello Claes,

Thank you for answering (and thanks a lot for yaws wiki).
Adding a big file (from 2 Mbytes to 20 Mbytes) to a Wiki page displays=20=

(after a while saying "Sending request to x.y.z.t): "The document=20
contains no data" in an alert dialog box ; it is using Firefox on=20
Windows (it gives another kind of error with another Web browser on=20
another OS). A smaller file (like 200 Kbytes) is OK. I have tried this=20=

with a Wiki I installed on Linux. No special message in the log=20
files...

Thanks again,
   J=E9r=F4me.

The code in setconf/2 is completely rewritten with the latest
release. It tries to load the new configuration smothly, i.e.
without stopping any virt servers that doesn't have to be stopped.
In earlier relases, all virt servers were stopped and the restarted
with the new config.

There are a number of config options that require restart though, such
as changing the logdir and a bunch of others too.

If setconf/2 returns need_restart, what is needed in embedded mode
is application:stop(yaws), application:start(yaws) and then redo the setconf/2.

If env {embedded, true} is set, yaws will start with an empty conf


What you describe above though, does indeed seem weird. That the same
setconf/2 works on on box and not on the other. It sure as hell isn't 
related to the kernel version. Something else is missing here.

I need more data to be able to guide you here ........

Here's what i have:

- --------------------------------
. box 1 (no problem)

[11:47:44]$ erl -pa trex -pa /usr/local/lib/yaws/ebin -yaws embedded
true -s gui -sname oliv3
Erlang (BEAM) emulator version 5.4.2.1 [source] [hipe]

Eshell V5.4.2.1  (abort with ^G)
(oliv3@...>
=INFO REPORT==== 7-Jan-2005::11:47:53 ===
Yaws: Listening to 127.0.0.1:2613 for servers
~ - jokasta under ./www

(oliv3@...>

- --------------------------------
. box 2

olivier@...$ erl -pa trex -pa
/usr/local/lib/yaws/ebin -yaws embedded true -s gui -sname oliv3
Erlang (BEAM) emulator version 5.4.3 [source] [hipe] [threads:0]

Eshell V5.4.3  (abort with ^G)
(oliv3@...> gui:start().
{error,need_restart}
(oliv3@...>

As you can see nothing happens on boot and manually starting
the gui fails.

How could i help track down this problem ? i'm not that
familiar with debugging erlang yet

I still need more information in order to say anything. 
What is the gui module doing for example.

basically the same thing as ybed.erl:

- -module(gui).
- -author('olivier@...').
- -compile(export_all).

- -include("/usr/local/lib/yaws/include/yaws.hrl").

start() ->
~    application:start(yaws),
~    GC = yaws_config:make_default_gconf(false),
~    SC = #sconf {port = 2613,
~                 servername = "jokasta",
~                 listen = {127,0,0,1},
~                 docroot = "./www"},
~    yaws_api:setconf(GC, [[SC]]).

Are you sure that you are using the same exact version of Yaws on the 
two boxes ?
Depending on the version you are using, the configuration of Yaws record 
might have changed between the two versions.

Seems to be it !

The working box has yaws-1.49 and the 'broken' one 1.51. Now i have
to find out which part of the configuration has changed..

Thanks,
