Leo Vasanko 123e910873 Add @kanta.clock hook replacing the UTC clock for all record and snapshot timestamps 2026-08-06 23:55:09 +00:00
Leo Vasanko f4e0c66907 Tests for rich logging, apply ruff formatting 2026-08-06 23:06:24 +00:00
Leo Vasanko 9c0b47ce38 Add kanta.bootstrap logger and configurable logging setup 
- Bootstrap records are now logged via kanta.bootstrap at INFO level.
- Existing databases log 'Using <path>' at DEBUG on kanta.bootstrap.
- New databases log 'Created <path>' at INFO on kanta.bootstrap.
- Renamed loggers: kanta.changes -> kanta.transaction, kanta.migrations -> kanta.migration.
- configure_logging() gains bootstrap/migration/transaction/skiproot kwargs.
- Default configure_logging() attaches a no-prefix stderr handler to kanta and stops propagation.
- With skiproot=False, child logger propagation flags are still applied but kanta itself is left untouched.
- Updated tests and docstrings.

Leo Vasanko 652d60b74b Add separate migration logging, logmigr callback, and log= override 
- Split transaction logger (kanta.changes) and migration logger (kanta.migrations).

- Add open(log=...) to suppress/redirect default migration logging.
- Add @kanta.logmigr callback for custom migration logging/summaries.
- Add transaction(log=...) to suppress/redirect transaction logging.
- Update tests for the new MigrationResult API and logging behaviour.

Leo Vasanko 96fd6b83dd Revised migration context: don't store changerecord unless something was changed, and always snapshot if and after changes done. 2026-06-15 22:14:03 +00:00
Leo Vasanko 1642b3f876 Stricter versioning: always store migrate version record, file must be within versions included in migrations. Log only for migrations that made changes. Allow deleting older migration functions when no longer required. 2026-06-15 03:09:45 +00:00
Leo Vasanko 526cd6eb80 Refactor Migrations internals, add caching to avoid reloading per each Kanta instance. Naming changed from MigrationRegistry to Migration, module from migrate to kanta.migrations. 2026-06-15 01:12:42 +00:00

Leo Vasanko 26101bc028 Add kanta.ctx SimpleNamespace for user variables. This is passed to migration functions if they take a second argument. Remove the old MigrationCtx system. 2026-06-14 19:54:23 +00:00
Leo Vasanko 3e6210d0e9 Add read only mode that doesn't use locking. Useful for inspection while the database is in use or when no changes are intended (except in RAM). 2026-06-14 19:35:06 +00:00
