From 576b69a944ee201368b6d016798e1df20be9acf6 Mon Sep 17 00:00:00 2001 From: Ivan Longin Date: Thu, 5 Sep 2024 11:00:07 +0200 Subject: [PATCH] Add `DataChain.listings()` method and use it in getting storages (#331) * first version of from_storage without deprecated listing * first version of from_storage without deprecated listing * fixing tests and removing prints, refactoring * refactoring listing static methods * fixing non recursive queries * using ctc in test session * fixing json * added DataChain.listings classmethod that returns list of ListingInfo objects for each cached listing * another test for listings * removed not needed filters * refactoring test * removed not needed catalog storage methods and their related codebase * fixing windows tests * returning to all tests * removed unlist_source method and related codebase * fixing dataset dependencies * added session on cloud test catalog and refactoring tests * using new listings method in from_storage * fixing test * fixing test * added dataset name dependencies test and fixes * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * small refactoring * refactor comments --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> --- src/datachain/catalog/catalog.py | 23 --------- src/datachain/cli.py | 18 ++----- src/datachain/data_storage/metastore.py | 29 +---------- src/datachain/data_storage/sqlite.py | 11 ---- src/datachain/dataset.py | 69 ++++++++++++++----------- src/datachain/lib/dataset_info.py | 4 ++ src/datachain/lib/dc.py | 47 ++++++++++++++--- src/datachain/lib/listing.py | 7 +++ src/datachain/lib/listing_info.py | 32 ++++++++++++ src/datachain/query/dataset.py | 4 +- tests/func/test_catalog.py | 26 +++++++--- tests/func/test_dataset_query.py | 24 +++++++-- tests/func/test_datasets.py | 31 ++++++----- tests/func/test_ls.py | 11 ++-- tests/unit/lib/test_datachain.py | 57 ++++++++++++++++++++ tests/unit/test_dataset.py | 28 ++++++++++ tests/unit/test_listing.py | 7 +++ tests/unit/test_storage.py | 34 ------------ 18 files changed, 282 insertions(+), 180 deletions(-) create mode 100644 src/datachain/lib/listing_info.py diff --git a/src/datachain/catalog/catalog.py b/src/datachain/catalog/catalog.py index 3a9a47af9..78d6f1460 100644 --- a/src/datachain/catalog/catalog.py +++ b/src/datachain/catalog/catalog.py @@ -1018,20 +1018,6 @@ def _row_to_node(d: dict[str, Any]) -> Node: return node_groups -
