< Yaws mailing list ~ crash in yaws code leaves connection hanging |

I'm using yaws 1.75 in embedded mode, and it seems that a crash in
the yaws code in some situations leaves the client connection open
and hanging.
Here is the specific situation that triggered this for me just
today:
- I started yaws in embedded mode and passed it a #sconf record with
opaque = { some_tuple, ... }. (This will cause the crash later...)
- I have an appmod that selects one of a few CGI scripts based on
the path, like so:
out (YawsArg = #arg{ pathinfo = "/foo" }) ->
yaws_api:call_cgi (YawsArg, "/path/to/foo.cgi");
out (YawsArg = #arg{ pathinfo = "/bar" }) ->
yaws_api:call_cgi (YawsArg, "/path/to/bar.cgi").
- Then a request for /appmod/foo will hang forever. A crash like
this is reported through error_logger:
Error in process <0.9696.0> on node 'my_node' with exit value: {function_clause,[{lists,foldl,[#Fun<yaws_server.48.125267158>,{["foo"],{[],[]}},{some_tuple, ...}]},{yaws_server,vdirpath,3},{yaws_server,mappath,3},{yaws_cgi,cgi_env...
So, yes, it seems to be a bug that I passed #arg.opaque as a tuple
instead of a list (opaque is not very opaque after all...but
that's another discussion).
The disturbing part is that the client connection is not closed
when the crash occurs.
Is there an easy fix to ensure that crashes within yaws itself are
detected and handled as nicely as crashes within user appmods or
auto-generated modeuls from .yaws files?
Thanks,
Mike

Agreed, there's some cruft in the opaque field e.g. vdir specifications
are there when they really should be a proper field in #sconf{}

Hmmm this needs to be debugged - I'll have a look at it. Thanks
for reporting.
Client socket should definitely die here.
