Definition at line 1873 of file migration.py.

◆ _create_index()

None homeassistant.components.recorder.migration._create_index	(	Callable[[], Session]	session_maker,
		str	table_name,
		str	index_name
	)

private

Create an index for the specified table.

The index name should match the name given for the index
within the table definition described in the models

Definition at line 430 of file migration.py.

◆ _delete_foreign_key_violations()

None homeassistant.components.recorder.migration._delete_foreign_key_violations	(	Callable[[], Session]	session_maker,
		Engine	engine,
		str	table,
		str	column,
		str	foreign_table,
		str	foreign_column
	)

private

Remove rows which violate the constraints.

Definition at line 813 of file migration.py.

◆ _drop_foreign_key_constraints()

None homeassistant.components.recorder.migration._drop_foreign_key_constraints	(	Callable[[], Session]	session_maker,
		Engine	engine,
		str	table,
		str	column
	)

private

Drop foreign key constraints for a table on specific columns.

This is not supported for SQLite because it does not support
dropping constraints.

Definition at line 699 of file migration.py.

◆ _drop_index()

None homeassistant.components.recorder.migration._drop_index	(	Callable[[], Session]	session_maker,
		str	table_name,
		str	index_name,
		bool \| None	quiet = `None`
	)

private

Drop an index from a specified table.

There is no universal way to do something like `DROP INDEX IF EXISTS`
so we will simply execute the DROP command and ignore any exceptions

WARNING: Due to some engines (MySQL at least) being unable to use bind
parameters in a DROP INDEX statement (at least via SQLAlchemy), the query
string here is generated from the method parameters without sanitizing.
DO NOT USE THIS FUNCTION IN ANY OPERATION THAT TAKES USER INPUT.

Definition at line 479 of file migration.py.

		str	query,
		list[str]	errors
	)

private

Execute a query or collect an error.

Definition at line 466 of file migration.py.

set[str] homeassistant.components.recorder.migration._find_schema_errors	(	HomeAssistant	hass,
		Recorder	instance,
		Callable[[], Session]	session_maker
	)

Definition at line 253 of file migration.py.

◆ _generate_ulid_bytes_at_time()

private

Return migration changes as a dict.

Definition at line 368 of file migration.py.

◆ _get_schema_version()

int | None homeassistant.components.recorder.migration._get_schema_version ( Session session )

private

Get the schema version.

Definition at line 183 of file migration.py.

◆ _initialize_database()

bool homeassistant.components.recorder.migration._initialize_database ( Session session )

private

Initialize a new database.

The function determines the schema version by inspecting the db structure.

When the schema version is not present in the db, either db was just
created with the correct schema, or this is a db created before schema
versions were tracked. For now, we'll test if the changes for schema
version 1 are present to make the determination. Eventually this logic
can be removed and we can assume a new db is being created.

Definition at line 2205 of file migration.py.

◆ _mark_migration_done()

None homeassistant.components.recorder.migration._mark_migration_done	(	Session	session,
		type[BaseMigration]	migration

private

Migrate columns to use timestamp.

Definition at line 1956 of file migration.py.

◆ _migrate_schema()

SchemaValidationStatus homeassistant.components.recorder.migration._migrate_schema	(	Recorder	instance,

		Callable[[], Session]	session_maker,
		SchemaValidationStatus	schema_status,
		int	end_version
	)

private

Check if the schema needs to be upgraded.

Definition at line 289 of file migration.py.

◆ _migrate_statistics_columns_to_timestamp()

None homeassistant.components.recorder.migration._migrate_statistics_columns_to_timestamp	(	Recorder	instance,
		Callable[[], Session]	session_maker,
		Engine	engine
	)

private

Migrate statistics columns to use timestamp.

Definition at line 2098 of file migration.py.

◆ _migrate_statistics_columns_to_timestamp_one_by_one()

None homeassistant.components.recorder.migration._migrate_statistics_columns_to_timestamp_one_by_one	(	Recorder	instance,
		Callable[[], Session]	session_maker
	)

private

Migrate statistics columns to use timestamp on by one.

If something manually inserted data into the statistics table
in the past it may have inserted duplicate rows.

Before we had the unique index on (statistic_id, start) this
the data could have been inserted without any errors and we
could end up with duplicate rows that go undetected (even by
our current duplicate cleanup code) until we try to migrate the
data to use timestamps.

This will migrate the data one by one to ensure we do not hit any
duplicate rows, and remove the duplicate rows as they are found.

Definition at line 2045 of file migration.py.

◆ _migrate_statistics_columns_to_timestamp_removing_duplicates()

None homeassistant.components.recorder.migration._migrate_statistics_columns_to_timestamp_removing_duplicates	(	HomeAssistant	hass,

None homeassistant.components.recorder.migration._modify_columns	(	Callable[[], Session]	session_maker,
		Engine	engine,
		str	table_name,
		list[str]	columns_def
	)

private

Modify columns in a table.

Definition at line 580 of file migration.py.

◆ _restore_foreign_key_constraints()

None homeassistant.components.recorder.migration._restore_foreign_key_constraints	(	Callable[[], Session]	session_maker,
		Engine	engine,
		list[tuple[str, str, str \| None, str \| None]]	foreign_columns
	)

private

None homeassistant.components.recorder.migration._update_states_table_with_foreign_key_options	(	Callable[[], Session]	session_maker,
		Engine	engine
	)

private

Add the options to foreign key constraints.

This is not supported for SQLite because it does not support
dropping constraints.

Definition at line 639 of file migration.py.

◆ _wipe_old_string_time_columns()

None homeassistant.components.recorder.migration._wipe_old_string_time_columns	(	Recorder	instance,

Check if live migration is possible.

Definition at line 264 of file migration.py.

◆ migrate_data_live()

None homeassistant.components.recorder.migration.migrate_data_live	(	Recorder	instance,
		Callable[[], Session]	session_maker,
		SchemaValidationStatus	schema_status
	)

Queue live schema migration tasks.

This must be called after live schema migration is completed.

Definition at line 413 of file migration.py.

◆ migrate_data_non_live()

None homeassistant.components.recorder.migration.migrate_data_non_live	(	Recorder	instance,
		Callable[[], Session]	session_maker,

	)

Do non-live data migration.

This must be called after non-live schema migration is completed.

		int	schema_version
	)

Return True if non-live data migration is needed.

This must only be called if database schema is current.

Definition at line 377 of file migration.py.

◆ post_migrate_entity_ids()

bool homeassistant.components.recorder.migration.post_migrate_entity_ids ( Recorder instance )

Remove old entity_id strings from states.

We cannot do this in migrate_entity_ids since the history queries
still need to work while the migration is in progress.

Definition at line 2187 of file migration.py.

◆ pre_migrate_schema()

None homeassistant.components.recorder.migration.pre_migrate_schema ( Engine engine )

Prepare for migration.

This function is called before calling Base.metadata.create_all.

errors caused by manual migration between database engines, for example importing an
SQLite database to MariaDB.
