[Zope-Checkins] CVS: Zope3/lib/python/Zope/Server/LineReceiver - LineServerChannel.py:1.1.2.7

[Shane Hathaway]

Update of /cvs-repository/Zope3/lib/python/Zope/Server/LineReceiver
In directory cvs.zope.org:/tmp/cvs-serv18340/LineReceiver

Modified Files:
      Tag: Zope3-Server-Branch
	LineServerChannel.py 
Log Message:
- Removed AlternateSocketMapMixin.  It was there to support multiple socket
maps, but if we really need multiple socket maps, it would be better to
change asyncore.  Had to update a lot of __init__ methods.

- Added IUsernamePassword and IFilesystemAccess, which provide a way to
implement all kinds of authentication schemes without FTP knowing about
any of the details.  Modified FTPServerChannel to work based on an
IFilesystemAccess object.

- Added detection of the ZOPE_SERVER_DEBUG env var.

- Added comments here and there.

- Fixed CRs :-)
