Hello List, I am new to Drupal and new to this list. For research purposes, I am surveying code repositories of the top 10 web applications using a modified version of StatSVN. Basically, I need to track source changes, over releases, in terms of "Lines of Code (LOC) matching a certain regexp". The functions/lines I am interested in are those somehow involved in handling HTTP request/session/response parameters. Of course, I allow a certain roughness in the analysis. I am trying to build a list of such functions/lines. What would you suggest to include? What would you grep for if you want to estimate the functions that are, even indirectly, related to processing of HTTP requests/sessions/responses? Any input is greatly appreciated. Thanks in advance. Cheers, -- Federico
