Just a heads-up for those not following CVS; I'm
fixing up an alternate
schema upgrader which will do the major schema updates and UTF-8
conversion for the 1.5 upgrade, and should be relatively friendly to
replication.
Since basically everything (cur & old) will be changed in the database,
can't we just update the master DB server *without* synchronization to
the slaves, and then set up the slaves "de novo"?
We could leave half of the slave servers in 1.4 format and serve
read-only wikipedia from there, while setting up the master and the
other slaves to 1.5. Then, serve wikipedia from the 1.5 master/slaves
and setup the remaining 1.4 slaves.
Shouldn't take much longer, seems less complicated and doesn't require
these fancy upgrade scripts you young people keep talking about ;.)
