Re: [PyWrapper-devel] First impressions...

[<m.d...@BG...>]

Peter,

there are no production installations of pywrapper2 yet. We intend to =
recommend fastcgi when possible, but nearly all our development =
installation use the standalone version cause its much easier to use. I =
have only tested the fastcgi version on mac osx with apache1.3 so far =
cause its pretty new. Before we were using mod_python which we installed =
here at the bgbm under debian. That reminds me that I have to update =
this installation...

The delay when starting the server is mainly due to the fact that =
pywrapper downloads and parses all models registered in the alias.txt =
file, currently by default http://rs.tdwg.org/tapir/cns/alias.txt
This takes quite some time and you should see some warning messages on =
the console about not understood xml schema tags (its ok like this). The =
startup time should be less for the subsequent times, cause pywrapper =
caches downloaded files locally.
