Well, cheap is relative. Some people consider it wasteful to keep creating new, essentially "identical" objects. > Perrin originally suggested connect_cached() as a solution to a transaction > bug > w.r.t Apache::DBI: Caching the whole Rose::DB object should have a similar effect, right? > Seems like the latest patch I sent achieves that with new_or_cached().

I can imagine all combinations of the two being useful in some circumstances. > All that's really necessary is to call DBI->connect_cached() rather than > DBI->connect().

Yes, definitely, only I don't want to hard-code the possible choices. I suspect the DBI->connect() (or whatever) call will end up being split out into its own method for easier customization. I'll think about it a bit more... -John ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
