yaws

Please help me find the cause of yaws hang on application stop.

I am new to Erlang and Yaws.  This is my first posting to this mailing
list so I will try my best to explain the problem.  I have embedded
Yaws into my application.  I can start my application from the Erlang
shell with application:start(toga).  In toga:start/2, the application
calls application:start(yaws) and Yaws is started properly and serves
pages.  The problem occurs when I type application:stop(toga) at the
Erlang shell.  In toga:stop/1, my application calls
application:stop(yaws) and hangs.  I tried leaving it in this hanged
state, hoping that the 5000 second timeout would occur.  It remained
hanged even after 3 hours.  A trace on the yaws processes showed no
shutdown messages.

I trimmed down my application to the bare essentials necessary to
exhibit the problem.  I am using yaws-1.56, running under Erlang 5.4.8
(R10B) compiled from source, on OpenBSD 3.5.  The problem also occurs
under WinXP SP2.  It is impossible to configure yaws under Windows so
I just copied the yaws-1.56 directory from the OpenBSD installation.

Here is the code:
http://tamale.net/junk/toga-0.1.tar.gz
http://tamale.net/junk/toga-0.1/ (extracted for online viewing)
Extract the application in your erlang/lib/ folder.  It expects to
find yaws in erlang/lib/yaws-1.56.
My yaws-1.56 directory: http://tamale.net/junk/yaws-1.56.configured.tar.gz

Thanks for your help.

Hi,

I recently modified the wiki code to become an appmod and in the process
noticed a problem:
the wiki code uses {ssi,{rel_path, ...'  to include the HTML template ,
which fails miserably due to the fact that yaws can not determine the
'fullpath' correctly. This in itself is correct as for appmods there is
no correct fullpath, and use of '{ssi,{abs_path,...' would most likely
be best to use for appmods.
However setting a default for fullpath to an empty list (docroot) will
make {ssi,{rel_path,...' work for appmods and does not harm anything
else (as it will be set properly in other cases). Just in case I also
put a default value for path and dir.

Patch included
