[Zope3-checkins] CVS: Zope3/src/zope/server/http - publisherhttpserver.py:1.4

[Jim Fulton]

Update of /cvs-repository/Zope3/src/zope/server/http
In directory cvs.zope.org:/tmp/cvs-serv5616/server/http

Modified Files:
	publisherhttpserver.py 
Log Message:
Added a Post-Mortem debugging HTTP server that enters Python's
post-mortem debugger when an error gets to the publisher.

To use this, copy zope.conf.in to zope.conf and change:


<server>
  type HTTP
  address 8080
</server>

to 

<server>
  type PostmortemDebuggingHTTP
  address 8080
</server>

Do this *after* logging in, so you don't catch Unauthorized errors.
