Overview ¶
Package migrationinit protects the current-schema initialization boundary. It supports a fresh database, the exact current schema, and one explicitly fingerprinted predecessors. Every other historical or drifted state fails before the migration driver can mutate it.

Constants ¶
const ( CoreVersion int64 = 92 // CoreShapeVersion is the migration version the shape constants below were // measured against. The digest and the object counts come from a live // catalog, so adding a migration cannot update them offline; leaving them // stale would pass every test and then fail the postflight shape check at // deploy time. A test requires these two to match, turning that into a // local failure with an explicit instruction. CoreShapeVersion int64 = 92 // CoreUpgradeShapeVersion is the predecessor version CoreUpgradeSchemaDigest // and the upgrade counts were measured against. Raising CoreUpgradeVersion // without remeasuring would make the upgrade path validate a predecessor // against another version's fingerprint.

Types ¶
type MigrationTableState ¶
MigrationTableState is the complete state of one golang-migrate version table. Rows must be exactly one whenever the table exists.
type SchemaShape ¶
type SchemaShape struct {
Digest string
Tables int64
Constraints int64
Indexes int64
Triggers int64
GuardFunctions int64
CoreIdentities int64
RuntimeControls int64
RuntimeSchemas int64
CurrentRuntime int64
RuntimeWires int64
CurrentWire int64
PreviousWire int64
BuiltInSkills int64
BuiltInSkillCases int64
}
SchemaShape is a closed current-schema fingerprint for one owner. The object counts are scoped to the owner's canonical tables.
type Snapshot ¶
type Snapshot struct {
Core MigrationTableState
Cloud MigrationTableState
NonBookkeepingObjects int64
CoreShape SchemaShape
CloudShape SchemaShape
ObsoleteCloudObjects int64
UnclassifiedBrowserAgents int64
CallbackOwnerIndexValid bool
}
Snapshot contains migration bookkeeping plus immutable catalog evidence.
func (Snapshot) ValidateCloudUp ¶
ValidateCloudUp returns true when the current Cloud schema is already installed.
func (Snapshot) ValidateCoreUp ¶
ValidateCoreUp returns true when the current schema is already installed.
