I can see why folks would want this, but I'd like to toss in a vote against it being on by default. It strikes me as spooky action at a distance -- because another process possibly on another machine saved the state of one of its objects, the objects in my current script start tossing exceptions or quietly changing their state. This would be bad for an I'm writing that has both short-lived pages and a longer-lived process that wants to have possibly out-of-sync data to keep track of state and state changes. I also think it'd be really surprising (in a bad way) to newbies. It feels a little like thread programming, where getting variables into a known state requires some kind of locking. Note that I'm not saying "don't do it" or "it's always bad", I'm just asking "please don't do it by default". And to touch on an earlier topic, I'm all for transaction support. - -- Peter Harkins - http://push.cx -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) Comment: If you don't know what this is, it's OK to ignore it. iD8DBQFEBMLJa6PWv6+ALKoRAjz0AJ9tT89VaTYly2ksc2OU1kSB6t3MTgCfaejL a7dWe5ddbcECf6VG+hsXQmg= =7mU0 -----END PGP SIGNATURE----- --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
