Summary: - propagate lower-level read and merge failures through `GetContext` via `read_status`, so `Get` and `GetEntity` preserve the original error instead of synthesizing `Corruption` when blob-backed reads or merge resolution fail - teach `GetMergeOperands` to resolve blob-backed default columns from wide-column entities, covering both the direct base-value path and the merge-plus-base path - add regression coverage for blob-read IO errors during `Get`/`GetEntity` merge resolution and for `GetMergeOperands` on blob-backed wide-column entities - fix the `DBFlushTest.MemPurgeCorrectLogNumberAndSSTFileCreation` test race by waiting for flush callbacks and cleaning up sync points ## Testing - `make db_blob_basic_test -j14` - `/usr/bin/perl -e 'alarm shift; exec ARGV' 60 ./db_blob_basic_test --gtest_filter='DBBlobBasicTest/DBBlobBasicIOErrorTest.GetBlob_IOError/*:DBBlobBasicTest/DBBlobBasicIOErrorTest.GetEntityMergeWithBlobBaseIOError/*'` ## Task T265824017, T265415808 Pull Request resolved: https://github.com/facebook/rocksdb/pull/14640 Reviewed By: anand1976 Differential Revision: D101690700 Pulled By: xingbowang fbshipit-source-id: 2b6fc357b37a01efa72a2d54dcff55be8992f42a
