[Framework-Team] repoze.zope2

[Martin Aspeli]

We should probably send this to the plone-developers list rather than
the framework team list... Sorry, not on my computer now so can't do
this efficiently, but the discussion belongs there.

And thanks! :)

> I was encouraged to write down the main differences between the "stock" Zope2
> publisher and the publisher that is inside repoze.zope2 (which is in use by the
> current Plone trunk).
>
> - Conflict error retry management is moved out into WSGI middleware
>  (repoze.retry).
>
> - Trace (-M) logging is moved out into WSGI middleware (see repoze.debug).
>
> - Access (apache-style) logging is moved out into WSGI middleware (see Paste's
>  translogger).
>
> - Transaction management is moved out into WSGI middleware (see repoze.tm).
>
> - Top-level exception handling is moved out into WSGI middleware (cgitb
>  or evalerror)
>
> - Logging exceptions to the console is now performed by middleware
>  (repoze.errorlog).
>
> - An alternate spelling for virtual hosting is supported (no
>  VirtualHostMonster needed).  See http://plope.com/Members/chrism/vhm_victory.
>  Note that traditional virtual hosting still works, however, as well.
>
> - You can return any iterable to the publisher (such as a file), and it will
>  be treated as the response.
>
> Some fallout from these differences:
>
> Some "advanced" stuff is configurable via the paste.ini file, such as the
> publisher output encoding ("encoding"), the Zope root object name ("appname"),
> and whether or not we try to do a redirect for a browser default
> ("browser_default_redirects").  These are set to the least surprising options by
> default.
>
> "standard_error_message" will not work because the publisher no longer acts as
> the top-level error handler.  A "pretty" exception handler will need to be
> plugged in as WSGI middleware.
>
> The "error_log" object will not work.  Use zope.errorlog instead (visit
> /__error_log__ in the browser).
>
> No testing has been done with "IStreamIterator" objects.  These may or may not
> work.  If they don't work, it's trivial to make them work.
>
> The most recent version of repoze.zope2 is 1.0 available from
> http://dist.repoze.org/zope2/latest/.  The subversion repository is
> http://svn.repoze.org/repoze.zope2/trunk/ .
>
> I'll be happy to help with any porting problems / questions.
