Re: vsaCore.utils

Hi Jagrata,

Following is a summary of some issues regarding the code 
review session we had on Saturday:

1. eol-native - It is my understanding that a file committed 
via subversion will have all occurrences of the EOL string 
stripped and replaced by the unix version ( \n ) when the 
eol-style setting is set to "native" in the file's subversion 
properties.    When a file stored in this manner on the 
repository is updated or checked out to a local machine then 
the local-machine's version of the eol string is inserted to 
replace the existing unix one.  

If this is an incorrect understanding of this setting then 
kindly let me know.

2. Python scripting in a Plone site:  You asked me whether we 
could instantiate an external method in a DirectoryView.  A 
DirectoryView is a product deployed in the CMF product family. 
 To expose python scripting to the zmi in a DirectoryView a 
file in a DirectoryView'ed directory must have the file 
extension: 'py' or 'cpy'.  This provides for the creation of 
an FSPythonScript object in the zmi DirectoryView object which 
is a python script with its source code stored in a file on 
the file system.  The convenience of this arrangement is not 
to be underestimated, however the usage of pythonscripts in a 
Plone skin also has disadvantages: (chiefly performance 
slowdown and security/permission issues).  An external python 
method performs a similar function except that it has no 
permission restrictions  except those of a python script 
running on the file system outside of zope.  Unfortunately, as 
of the current release of PLone/CMF there is no provision for 
an external python method to be exposed in a DirectoryView. 
 The DirectoryView only supports zope objects of the following 
types:

Page Template
Script (Python)
Properties Object
Image
Controller Page Template
Controller Python Script
STX Method
Controller Validator
File
Z SQL Method
FSForm
DTML Method

This is pretty much a final list for now.

Best Regards
Medur
