Issue: We observed that, when creating a database based on the same
gORM schema multiple times, indexes could appear in different orders,
hurting determinism for use-cases like schema comparison.
In order to fix this, it's simple to switch the ParseIndexes function
to return a list of indices rather than a map, so the callers will
iterate in deterministic order.
* refactor: distinguish between UniqueIndex and Index
* add test
* add ParseIndex test
* modify unique to constraint
* modify unique to constraint
* fix MigrateColumnUnique
* fix test
* fix unit test
* update test mod
* add MigrateColumnUnique to Migrator interface
* fix format lint
* add comment
* go mod tidy
* revert: revert MigrateColumn
* resolve conflicts
Go 1.22 goes somewhat toward addressing the issue using reflect
MethodByName disabling linker deadcode elimination (DCE) and the
resultant large increase in binary size because the linker cannot
prune unused code because it might be reached via reflection.
Go Issue golang/go#62257 reduces the number of incidences of this
problem by leveraging a compiler assist to avoid marking functions
containing calls to MethodByName as ReflectMethods as long as the
arguments are constants.
An analysis of Uber Technologies code base however shows that a number
of transitive imports still contain calls to MethodByName with a
variable argument, including GORM.
In the case of GORM, the solution we are proposing is because the
number of possible methods is finite, we will "unroll" this. This
demonstrably shows that GORM is not longer a problem for DCE.
