V1.5.12

[flarco]

New Features

• --home-dir flag: New flag across sling run and all sling conns subcommands (list, test, set, unset, exec, discover) to specify a custom sling home directory. Sets SLING_HOME_DIR and reloads connections accordingly.

• Column merge with defaults (+ prefix): Stream-level columns: entries prefixed with + now merge with defaults.columns instead of replacing them. Use +column_name: ~ to unset a default. Without +, legacy replace behavior is preserved.

• Pipeline store variables in replications: {store.xxx} variables set in pipeline steps are now accessible in inline replication where: and sql: fields.

• API spec range_step support: Added range_step to the endpoint context map, enabling three-part range expressions for backfill.

• API spec state variable rendering in jmespath / jq: State variables (e.g. {state.endpoint_name}) are now resolved inside jmespath and jq response record expressions.

Bug Fixes

• SLING_LOGGING env from replication: Moved SLING_LOGGING env handling from per-task to replication-level so it takes effect before stream execution and properly reinitializes the logger.

• Direct insert incremental state: writeToDbDirectly now calls SyncColumns() and SyncStats() so incremental state (e.g. datetime update keys) is correctly captured after direct insert writes.

• Auth token refresh on retry: API retry logic now refreshes HTTP request headers from conn.State.Auth.Headers before resending, fixing stale token issues after server-side token rotation (both single-request and mid-pagination scenarios).

• Windows path handling: CleanWindowsPath applied to local file locations in ParseLocation, API spec file:// paths, env file paths, and SLING_HOME_DIR.

• Oracle chunking with custom SQL: Fixed AS table alias syntax for Oracle (which doesn't support AS for subquery aliases).
