Add migrate_columns() and supporting functions for Phase 2 of the 0.14.6 → 2.0 migration: - analyze_columns(): Identify columns needing type labels - migrate_columns(): Add core type markers to column comments - NATIVE_TO_CORE_TYPE mapping for type conversion - Support for bool/datetime special cases - Dry-run mode for previewing changes Also adds placeholder stubs for Phase 3-4 migration functions: - migrate_external(): For external storage migration - migrate_filepath(): For filepath attribute migration - finalize_migration(): For Phase 4 finalization These functions implement the migration guide documented in datajoint-docs/src/how-to/migrate-from-0x.md.

The tests test_sigint, test_sigterm, test_suppress_dj_errors, and test_populate_exclude_error_and_ignore_jobs were flaky due to a race condition: jobs created with scheduled_time=NOW(3) might not pass the scheduled_time <= NOW(3) check if checked in the same millisecond. Fix by using delay=-1 in auto-refresh during populate(), ensuring jobs are scheduled 1 second in the past and immediately schedulable. Also update test_populate_exclude_error_and_ignore_jobs to use delay=-1 in its explicit refresh() call. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Replace bare except: with except ImportError: in diagram.py - Replace assert statements with explicit raises in blob.py - Replace assert False with explicit raises in expression.py and declare.py - Implement hash verification in objectref.py Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
dj.key was removed in 2.0 but was still listed in __all__ without being imported or defined. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Remove `schema` alias for `Schema` (use `dj.Schema` instead of `dj.schema`) - Remove `Di` alias for `Diagram` (use `dj.Diagram` or `dj.ERD`) - Update all examples, tests, and docstrings Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Update outdated docs.datajoint.com URLs to new paths: - diagram.py: /how-to/installation/ - heading.py: /how-to/migrate-from-0x/ - expression.py: /how-to/migrate-from-0x/ Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
