1-38: Verify and add imports for StreamState and Literal.The new methods reference

Critical issues: Missing self, undefined type, and incorrect logic.
This method has several blockers preventing it from working:
- Missing
selfparameter: Line 284 needsselfas the first parameter - Undefined
StreamStatetype: Need to importStreamStatefrom the appropriate module - Parameter name mismatch: Calling
get_state_provider(stream_name=stream_name)but that method expectssource_name, notstream_name(see lines 253-266) - Return type mismatch:
get_state_provider()returnsStateProviderBase, notStreamState | None
The intent seems to be retrieving state for a specific stream, but get_state_provider() requires a source name and returns a provider interface, not individual stream state. Would you like to clarify the intended behavior here? Perhaps this should delegate to a method on the StateProviderBase to extract a specific stream's state? wdyt?
Here's a potential fix assuming StateProviderBase has a method to get individual stream state:
- def get_state(
- stream_name: str,
- ) -> StreamState | None:
+ def get_state(
+ self,
+ stream_name: str,
+ source_name: str,
+ ) -> StreamState | None:
"""Return a stream state object for the provided stream name.
This is a thin wrapper around the internal `StateProvider` interface.
"""
- return self.get_state_provider(stream_name=stream_name)
+ state_provider = self.get_state_provider(source_name=source_name)
+ return state_provider.get_state_for_stream(stream_name) # Assuming such a method existsNote: You'll also need to add the import for StreamState at the top of the file.
Committable suggestion skipped: line range outside the PR's diff.
| def set_state( | ||
| stream_name: str, | ||
| stream_state: StreamState | dict, | ||
| ) -> None: | ||
| """Set a stream state object for the provided stream name. | ||
| This is a thin wrapper around the internal `StateWriter` interface. | ||

❓ Verification inconclusive
Missing self and undefined type; placeholder implementation.
The method signature has the same critical issues as get_state:
- Missing
selfparameter: Line 293 needsselfas the first parameter - Undefined
StreamStatetype: Need to importStreamState
Additionally, the method body is a placeholder (...). Since this is a draft PR, that might be intentional, but wanted to flag it. When implementing, you'll likely need to delegate to the StateWriter interface via get_state_writer(), perhaps something like:
def set_state(
self,
stream_name: str,
stream_state: StreamState | dict,
source_name: str,
) -> None:
"""Set a stream state object for the provided stream name.
This is a thin wrapper around the internal `StateWriter` interface.
"""
state_writer = self.get_state_writer(source_name=source_name)
state_writer.write_state(stream_name, stream_state) # Assuming such a method existsDoes that align with your intended design? wdyt?
Add missing self, import StreamState, and implement the placeholder body
- Could you add
selfas the first parameter ofset_state? - Could you import the
StreamStatetype? - Could you replace
...with a call toStateWriter(e.g.self.get_state_writer(...).write_state(...))? wdyt?

In airbyte/caches/base.py around lines 292 to 300, the set_state method is
missing self, the StreamState type is not imported, and the method body is a
placeholder; change the signature to include self as the first parameter, add an
import for StreamState at the top of the file, and replace the ellipsis with a
call to the StateWriter usage on this instance (e.g. obtain the writer via
self.get_state_writer(...) and call write_state(stream_name, stream_state) or
equivalent method) so the wrapper forwards the stream name and state to the
internal StateWriter.

🧩 Analysis chain
Missing self, undefined type, and formatting issue; placeholder implementation.
A few issues to address:
- Missing
selfparameter: Line 304 needsselfas the first parameter - Missing import:
Literalneeds to be imported fromtyping(it's likely already imported at line 7, but needs to be added to the import list) - Extra blank line: Line 302 has too many blank lines (flagged by linter E303)
- Placeholder implementation: The method body is
...which is expected for a draft PR
When implementing, this could iterate over the streams and copy state from this cache to the target cache. Something like:
def migrate_state(
self,
streams: list[str] | Literal["*"],
to_cache: CacheBase,
source_name: str,
) -> None:
"""Copies all matching stream states to the specified `Cache` object.
This is a thin wrapper around the respective `Cache` objects'
`get_state` and `set_state` methods.
"""
stream_list = self._catalog_backend.stream_names if streams == "*" else streams
for stream_name in stream_list:
state = self.get_state(stream_name, source_name)
if state is not None:
to_cache.set_state(stream_name, state, source_name)Would this match your vision for the feature? wdyt?

Add missing self, import Literal, and remove extra blank line
- Include
selfas the first parameter in themigrate_statesignature. - Add
from typing import Literalto the import statements. - Remove the extra blank line immediately above
migrate_state. - The body is currently a placeholder (
...); will you implement the stream iteration and state-transfer logic here? wdyt?
