| Improve util.FieldStorage efficiency
------------------------------------
Key: MODPYTHON-93
URL: http://issues.apache.org/jira/browse/MODPYTHON-93
Project: mod_python
Type: Improvement
Components: core
Versions: 3.3
Reporter: Jim Gallacher
Assigned to: Jim Gallacher
Priority: Minor
Form fields are saved as a list in a FieldStorage class instance. The class implements a __getitem__ method to provide dict-like behaviour. This method iterates over the complete list for every call to __getitem__. Applications that need to access all th
e fields when processing the form will show O(n^2) behaviour where n == the number of form fields. This overhead could be avoided by creating a dict (to use as an index) when the FieldStorage instance is created.
Mike Looijmans has been investigating StringField and Field as well. It is probably reasonable to include information on his work in this issue as well, so that we can consider all of these efficiency issues in toto.
