From 4588cbeee8f8ca06aa7d515dbb2d2162d72ba043 Mon Sep 17 00:00:00 2001 From: tegwick Date: Sun, 8 Feb 2026 18:03:35 +0100 Subject: [PATCH] feat(spaces): implement Phase 8 Git History Tracking Implements optional git-based version control for information spaces: - HistoryConfig model for configuring history tracking - Commit, Branch, HistoryEntry, DiffResult models - IHistoryBackend and IHistoryQuery interfaces - GitHistoryBackend using git CLI for version control - GitHistoryEventHandler for event-driven auto-commits - HistoryEventCoordinator for managing space history - HistoryQueryService for high-level history queries - Automatic commits on DOCUMENT_ADDED/REMOVED/CONTENT_CHANGED events - Support for: * Commit log with pagination and filtering * Diff between versions * File content at specific versions * Branch creation and switching * Version restoration * Uncommitted changes detection - 43 comprehensive unit tests with git availability checks Co-Authored-By: Claude Opus 4.5 --- markitect/spaces/__init__.py | 38 ++ markitect/spaces/history/__init__.py | 48 +- markitect/spaces/history/events.py | 286 ++++++++ markitect/spaces/history/git_backend.py | 521 +++++++++++++++ markitect/spaces/history/interfaces.py | 350 ++++++++++ markitect/spaces/history/models.py | 257 ++++++++ markitect/spaces/history/queries.py | 258 ++++++++ tests/unit/spaces/test_history.py | 838 ++++++++++++++++++++++++ 8 files changed, 2587 insertions(+), 9 deletions(-) create mode 100644 markitect/spaces/history/events.py create mode 100644 markitect/spaces/history/git_backend.py create mode 100644 markitect/spaces/history/interfaces.py create mode 100644 markitect/spaces/history/models.py create mode 100644 markitect/spaces/history/queries.py create mode 100644 tests/unit/spaces/test_history.py diff --git a/markitect/spaces/__init__.py b/markitect/spaces/__init__.py index d53b5b35..097c32a4 100644 --- a/markitect/spaces/__init__.py +++ b/markitect/spaces/__init__.py @@ -83,6 +83,27 @@ from .composability import ( ) from .composability.service import CircularReferenceError +# Phase 8: History Tracking (Optional) +from .history import ( + # Models + Commit, + Branch, + HistoryEntry, + DiffResult, + DiffLine, + DiffType, + HistoryConfig, + # Interfaces + IHistoryBackend, + IHistoryQuery, + # Implementations + GitHistoryBackend, + GitError, + GitHistoryEventHandler, + HistoryEventCoordinator, + HistoryQueryService, +) + __all__ = [ # Models "InformationSpace", @@ -130,4 +151,21 @@ __all__ = [ "IAccessControlRepository", "SqliteSpaceReferenceRepository", "SqliteAccessControlRepository", + # History - Models + "Commit", + "Branch", + "HistoryEntry", + "DiffResult", + "DiffLine", + "DiffType", + "HistoryConfig", + # History - Interfaces + "IHistoryBackend", + "IHistoryQuery", + # History - Implementations + "GitHistoryBackend", + "GitError", + "GitHistoryEventHandler", + "HistoryEventCoordinator", + "HistoryQueryService", ] diff --git a/markitect/spaces/history/__init__.py b/markitect/spaces/history/__init__.py index d8948eea..906858e4 100644 --- a/markitect/spaces/history/__init__.py +++ b/markitect/spaces/history/__init__.py @@ -1,13 +1,43 @@ """ -Git history tracking for Information Spaces (Optional Phase 8). +History tracking module for Information Spaces. -This package provides version control integration: -- IHistoryBackend: Abstract history backend interface -- GitHistoryBackend: Git implementation -- Event-driven commit triggers -- History query API (log, diff, branches) -- Versioned read/render operations +Provides optional git-based version control for space content, +enabling commit history, diffs, and version restoration.
