From 5b69fd65cd5a498ede4fa7e709a83c33fd18b4cc Mon Sep 17 00:00:00 2001 From: phernandez Date: Wed, 11 Jun 2025 18:19:17 -0500 Subject: [PATCH] fix: resolve case-insensitive project switching database lookup issue MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix project switching bug where case-insensitive matching worked but caused database lookup failures for subsequent operations. **Problem:** - switch_project('personal') succeeded (case-insensitive matching) - get_current_project() failed with 'Project personal not found' - Session stored user input case instead of canonical database name **Solution:** - Find project by permalink (case-insensitive) in switch_project - Store canonical project name from database in session - Use canonical name for all API calls and responses **Test Coverage:** - Added comprehensive case-insensitive project switching tests - Added tests for case preservation in project listings - Added tests for session state consistency after case switching - Added error handling tests for non-existent projects **Files Changed:** - src/basic_memory/mcp/tools/project_management.py: Fixed switch_project logic - test-int/mcp/test_project_management_integration.py: Added test coverage **Test Cases Now Passing:** - ✅ switch_project('personal') → finds 'Personal' project - ✅ get_current_project() → works with canonical name - ✅ Project summary shows stats correctly - ✅ Case-insensitive matching for all case variations - ✅ Error handling for non-existent projects 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src/basic_memory/config.py | 13 +- .../mcp/tools/project_management.py | 28 +- src/basic_memory/schemas/project_info.py | 4 +- src/basic_memory/services/project_service.py | 2 +- .../test_project_management_integration.py | 259 ++++++++++++++++++ 5 files changed, 287 insertions(+), 19 deletions(-) diff --git a/src/basic_memory/config.py b/src/basic_memory/config.py index 0c1ef0b6..40817b51 100644 --- a/src/basic_memory/config.py +++ b/src/basic_memory/config.py @@ -256,11 +256,14 @@ def get_project_config(project_name: Optional[str] = None) -> ProjectConfig: # the config contains a dict[str,str] of project names and absolute paths assert actual_project_name is not None, "actual_project_name cannot be None" - project_path = app_config.projects.get(actual_project_name) - if not project_path: # pragma: no cover - raise ValueError(f"Project '{actual_project_name}' not found") + project_permalink = generate_permalink(actual_project_name) - return ProjectConfig(name=actual_project_name, home=Path(project_path)) + for name, path in app_config.projects.items(): + if project_permalink == generate_permalink(name): + return ProjectConfig(name=name, home=Path(path)) + + # otherwise raise error + raise ValueError(f"Project '{actual_project_name}' not found") # Create config manager @@ -335,4 +338,4 @@ def setup_basic_memory_logging(): # pragma: no cover # Set up logging -setup_basic_memory_logging() +setup_basic_memory_logging() \ No newline at end of file diff --git a/src/basic_memory/mcp/tools/project_management.py b/src/basic_memory/mcp/tools/project_management.py index a9a72ff0..90827498 100644 --- a/src/basic_memory/mcp/tools/project_management.py +++ b/src/basic_memory/mcp/tools/project_management.py @@ -85,14 +85,20 @@ async def switch_project(project_name: str, ctx: Context | None = None) -> str: response = await call_get(client, "/projects/projects") project_list = ProjectList.model_validate(response.json()) - # Check if project exists - project_exists = any(p.permalink == project_permalink for p in project_list.projects) - if not project_exists: + # Find the project by permalink (case-insensitive) + target_project = None + for p in project_list.projects: + if p.permalink == project_permalink: + target_project = p + break + + if not target_project: available_projects = [p.name for p in project_list.projects] return f"Error: Project '{project_name}' not found.
