HOW DOES ENANO'S UPGRADER WORK?
Versions of Enano are organized into branches and then specific versions by
version number. The upgrader works by using a list of known version numbers
and then systematically executing upgrade schemas for each version.
When the user requests an upgrade, the first thing performed is a migration
check, which verifies that they are within the right branch. If they are not
within the right branch the upgrade framework will load a migration script
which will define a function named MIGRATE(). Performing more than one
migration in one pass will probably never be supported. How that works for
UX in 1.3.x/1.4.x I know not yet.
After performing any necessary branch migrations, the framework will perform
any upgrades within the target branch, which is the first two parts
(delimited by periods) of the installer's version number defined in the
installer's common.php.
enano_perform_upgrade() will only do upgrades. Not migrations. The two as
illustrated within this installer are very different.
