From 4504338a76d30ab1cd21581e4cf3f9b2e8b90f0c Mon Sep 17 00:00:00 2001 From: Mischa Diehm Date: Fri, 26 Dec 2025 10:17:19 +0100 Subject: [PATCH 1/9] feat(introspection): add config introspection for tracing value origins Implement "Where did X come from?" feature inspired by Dynaconf pattern. Enables users to trace configuration value sources via `nw info --trace`. - Add introspection.py with LoaderType, FieldHistory, ConfigHistory types - Add _history tracking to DeviceConfig, DeviceGroup, GeneralConfig models - Add CredentialSource and resolve_credentials_with_source() to credentials.py - Add SSH config provenance tracking in sync_ssh.py - Add --trace flag to info command for source column display - Add unit tests for introspection module - Add integration tests for --trace output Closes #37, #38, #39 --- src/network_toolkit/commands/info.py | 13 +- src/network_toolkit/commands/sync_ssh.py | 30 ++ src/network_toolkit/common/table_providers.py | 97 +++-- src/network_toolkit/config.py | 155 ++++++++ src/network_toolkit/credentials.py | 202 +++++++++++ src/network_toolkit/introspection.py | 279 ++++++++++++++ tests/test_info_trace.py | 288 +++++++++++++++ tests/test_introspection.py | 342 ++++++++++++++++++ 8 files changed, 1373 insertions(+), 33 deletions(-) create mode 100644 src/network_toolkit/introspection.py create mode 100644 tests/test_info_trace.py create mode 100644 tests/test_introspection.py diff --git a/src/network_toolkit/commands/info.py b/src/network_toolkit/commands/info.py index 9f0baed..9350fe9 100644 --- a/src/network_toolkit/commands/info.py +++ b/src/network_toolkit/commands/info.py @@ -65,6 +65,14 @@ def info( verbose: Annotated[ bool, typer.Option("--verbose", "-v", help="Enable verbose logging") ] = False, + trace: Annotated[ + bool, + typer.Option( + "--trace", + "-t", + help="Show detailed source provenance for all configuration values", + ), + ] = False, interactive_auth: Annotated[ bool, typer.Option( @@ -81,6 +89,7 @@ def info( Examples: -

refactor(introspection): consolidate credential resolution and DRY config history - Extract ConfigHistoryMixin for shared history tracking methods - Make _resolve_username/password delegate to _with_source() variants - Remove value field from CredentialSource (security improvement) - Remove unused CredentialResolutionTrace class - Add sensitive field masking to ConfigHistory.to_dict() - Simplify _get_credential_source() to use resolver - Fix path string replacement with proper Path operations Net reduction: -159 lines, eliminates duplicate resolution logic ---
