I like to grep through logs and see all lines that involve a single session. I make my own custom log for this purpose, say foo.log. I have been sticking 32 char session_ids into an instance array of my Logger, and using @session_ids.index(session_id) as a unique abbreviation string for logging. Abbreviation is handy when several people are working on a single customer problem - you can''t read a 32 char string over the phone and get it right. Since there are only a few dozen concurrent sessions, three alphanumeric characters are enough to uniquely specify all the sessions in a single day''s logs. The ''array index'' approach has lots of problems: 1) server restarts change the abbreviation. 2) sessions spanning the midnight logrotate roll-over are scrambled because I reset the ids into a fresh array at that time. If I didn''t, three chars wouldn''t be enough. 3) each webserver has a private list of abbreviations, so it takes extra work to track a single session across multiple servers. 4) it''s clumsy to garbage collect old sessions. ... In previous C/C++ systems I memory-mapped a logging id to a file, and wrote code to manage the sharing (locking). In Rails, I guess I can do the same with the database. But the problem seems so commonplace that I want to make sure I''m not overlooking an existing solution. I''m a web newbie, and the value of the Session ID seems so universal to all web apps, and the shortcomings likewise so universal, that somebody must have a multi-process (even multi-system) abbreviator already? One that can "roll-over" all but the open sessions on command? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
