Upgrade to web.py 0.2

If you are migrating from the "one big file" version of web.py to the .2 version, you have to make some changes to your code.

Downloading web.py 0.2

From the command line, cd to the directory you wish to install web.py and run the following command:

svn export http://webpy.org/svn/trunk/web/ 

Remove web.py and web.pyc from the loadpath.

web.run()

Most importantly, upvars() was removed. We have to change the run line from:

if __name__ == '__main__': web.run(urls)

to:

if __name__ == "__main__": web.run(urls, globals())

web.config

If you use a db, change web.db_parameters and web.db_printing to web.config.db_paramters and web.config.db_printing respectively.

debugging

web.py 0.1:

web.internalerror = web.debugerror
if __name__ == '__main__': web.run(urls, web.reloader)

web.py 0.2

web.webapi.internalerror = web.debugerror
if __name__ == "__main__": web.run(urls, globals(), web.reloader)

fastcgi with apache

web.py 0.1:

web.runwsgi = web.runfcgi

web.py 0.2:

def runfcgi_apache(func):
  web.wsgi.runfcgi(func, None)

web.wsgi.runwsgi = runfcgi_apache
