Changelog

Unreleased

Added

  • Add method to TableAdapter which accepts a Python dictionary.
  • Added an Arrow adapter which supports reading/writing arrow tables via RecordBatchFileReader/RecordBatchFileWriter.
  • Add an alembic catalog migration script to rename path parameters of HDF5 nodes to dataset.

Changed

  • Make tiled.client accept a Python dictionary when fed to write_dataframe().
  • The generated_minimal example no longer requires pandas and instead uses a Python dict.
  • Remove unused pytest-warning ignores from test_writing.py.
  • Rename argument in hdf5_lookup function from path to dataset to reflect change in ophyd_async

Fixed

  • A bug in Context.__getstate__ caused picking to fail if applied twice.

v0.1.0b5 (2024-06-27)

Added

Fixed

  • When authenticated as a Service Principal, display the SP's uuid in the client Context repr.
  • The dependency json-merge-patch, introduced in v0.1.0b4, was missing from some pip selectors.

v0.1.0b4 (2024-06-18)

Changed

  • Minor implementation changes were necessary to make Tiled compatible with Numpy 2.0.
  • For improved security, the server-side array slicing function has been refactored to avoid using eval(). To be clear: there were no known exploitable vulnerabilities in the eval() approach. The input was validated against a regular expression before being passed to eval(). However, avoiding eval() altogether is better practice for defense-in-depth against potential code injection attacks due to current or future bugs in Tiled or its upstream dependencies.

v0.1.0b3 (2024-06-04)

Added

  • Added a new HTTP endpoint, PATCH /api/v1/metadata/{path} supporting modifying existing metadata using a application/json-patch+json or a application/merge-patch+json patch.
  • Added client-side methods for replacing, updating (similar to dict.update()), and patching metadata.

Fixed

  • Fixed regression introduced in the previous release (v0.1.0b1) where exceptions raised in the server sent no response instead of properly sending a 500 response. (This presents in the client as, "Server disconnected without sending a response.") A test now protects against this class of regression.

v0.1.0b2 (2024-05-28)

Changed

  • Customized default logging configuration to include correlation ID and username of authenticated user.
  • Added --log-timestamps CLI flag to tiled serve ... to opt in to including timestamp prefix in log messages.

v0.1.0b1 (2024-05-25)

Added

  • Support for FullText search on SQLite-backed catalogs

Fixed

  • Updated BaseClient.formats to use the dict structure for specs.
  • The tiled serve directory --watch function was not compatible with recent anyio

v0.1.0a122 (23 May 2024)

Fixed

  • A dependency on fastapi was introduced in tiled.adapters. This has been removed.

v0.1.0a121 (21 May 2024)

Added

  • The tiled serve ... CLI commands now accept a --log-config option, pointing to a custom uvicorn logging configuration file. An example file was added to the repository root, example_log_config.yml.
  • Added tiled.adapters.protocols which will provide possibility for user to implement their custom adapters in a way that satisfies mypy.
  • Added tiled.client.smoke with a utility for walking a node and ensuring that the data in it can be read.
  • Added tiled.client.sync with a utility for copying nodes between two Tiled instances.
  • Show authentication state in Context repr.

Changed

  • SQLite-backed catalogs now employ connection pooling. This results in a significant speed-up and avoids frequently re-opening the SQLite file.
  • Metadata returned from the use of the select_metadata is now a one-item dictionary with 'selected' as the key, to match default type/behavior.
  • The method BaseClient.data_sources() returns dataclass objects instead of raw dict objects.
  • tiled.client.sync has conflict handling, with initial options of 'error' (default), 'warn', and 'skip'

Fixed

  • Propagate setting include_data_sources into child nodes.
  • Populate attributes in member data variables and coordinates of xarray Datasets.
  • Update dependencies.
  • Fix behavior of queries In and NotIn when passed an empty list of values.

v0.1.0a120 (25 April 2024)

Fixed

  • The content-encoding blosc was recently upgraded from Blosc to Blosc2. The content-encoding has been renamed to blosc2 to avoid version confusion between different versions of Tiled servers and clients.

v0.1.0a119 (24 April 2024)

Fixed

  • Metric-reporting had an error when compress timing was recorded but content-encoding header was unset.

v0.1.0a118 (23 April 2024)

Added

  • Python 3.12 support
  • Added tiled.adapters.resource_cache for caching file handles between requests.

Removed

  • Removed object cache from the codebase. If object_cache is included in the server configuration file, a warning is raised that this configuration has no effected.

Fixed

  • The configuration setting tiled_admins did not work in practice. If a user in the list was already an admin (such as, after a server restart) an error was raised on startup.
  • The table creation statements for PostgreSQL were not committed. (This may have been a regression due to a change in SQLAlchemy defaults.)
  • Tolerate HTTP responses that are missing a x-tiled-request-id header, such as when a proxy server responds with an error.
  • Use httpx status code sentinels (instead of starlette ones) for typing client-side status codes.

Changed

  • Removed upper bound version pin on dask.
  • Switched from blosc to blosc2.
  • Made client objects dask-serializable
  • Added support for registering multiple Assets with a DataSource in an update

Other

  • Usage of deprecated Pydantic 2.x APIs was updated.
  • Specify a fallback-version, 0.0.0, to be used when the version-detection code cannot run.

v0.1.0a117 (28 March 2024)

Added

  • Support for specifying the format that uploaded data will be stored in.
  • Support for storing uploaded tabular data in CSV format.
  • A new HTTP endpoint, PATCH /api/v1/table/partition/{path} supporting appending rows to a tabular dataset.
  • A new method DataFrameClient.append_partition.
  • Support for registering Groups and Datasets within an HDF5 file
  • Tiled version is logged by server at startup.

Fixed

  • Critical regression that broke tiled serve directory ... CLI.

Other

  • Updated the pydantic version in the pyproject.toml. Now the allowed versions are >2.0.0 - <3.0.0 .
  • Changes to prepare for upcoming numpy 2.0 release
  • Changes to address deprecations in FastAPI
