Initial plan: implement weak reference finalizer and global reference management

[Copilot]

Planning PR for implementing memory management improvements in the Robot Framework namespace analysis pipeline. No code changes have been made — implementation was aborted before it began.

Scope (unimplemented)

• Weak reference finalizer on Namespace — add weakref.finalize() as a safety net for namespaces GC'd without an explicit invalidate() call, complementing the existing WeakMethod-based event cleanup and the sentinel-based finalizers already present in ImportsManager
• python_executable in LibraryMetaData — include the interpreter path in cache metadata so disk caches are invalidated when the Python executable changes (virtual environment switches)
• Global reference management — cross-namespace aggregation of keyword/variable/library references to support workspace-wide "find all references"

Original prompt

Start implementation

The user has attached the following file paths as relevant context:

• .github/copilot-instructions.md

[Chronological Review: The conversation began with the user inquiring about the implementation of a weak reference finalizer. This led to discussions about documentation, commit messages, and various aspects of a namespace analyzer. The user expressed concerns about variable resolution, import handling, and the need for a global reference management system. The conversation evolved to include considerations for diagnostics, cache management, and the necessity of regression tests for the language server. The user concluded by requesting to start the implementation phase.]

[Intent Mapping:

1. "könnte man hier nicht auch einen weakref finalizer verwenden?" - User requested implementation of a weak reference finalizer.
2. "kannst du das mal implemetieren?" - User asked for the implementation of the weak reference finalizer.
3. "dann dokumentier mal das wir das umgesetzt haben" - User requested documentation of the implementation.
4. "dann schreib mal ein commit message für diese änderungen" - User asked for a commit message for recent changes.
5. "wir haben jetzt im Namespace noch eine eigene auflösung für variablen..." - User discussed variable resolution in the namespace.
6. "ich frage mich gerade wie es language server implementationen wie für rust oder python machen?" - User inquired about language server implementations.
7. "was ist mit dem import handling und so?" - User raised questions about import handling.
8. "ok, an welchen stellen brauchen wir denn das ast-model..." - User questioned the necessity of the AST model.
9. "C mit einplanen." - User emphasized the need for caching and updating information.
10. "ja, das sollst du" - User confirmed the need for a plan.
11. "in phase 1-5 fehlt mir irgendwie noch das mit dem import handling..." - User pointed out missing elements in the implementation phases.
12. "ja, nur bei den NamespaceCacheMeta brauchst du die python_executable: str..." - User clarified requirements for NamespaceCacheMeta.
13. "ja, es gibt noch mehr offene punkte..." - User highlighted the need for regression tests.
14. "um die ganzen Referenzen auf Keywords, Variablen, Libraries usw. vernünftig..." - User suggested a global reference management system.
15. "was meinst du mit: Unused-Detection decision since it's no longer a separate phase?" - User sought clarification on unused detection.
16. "ok, dann denke ich haben wir alles. oder fehlt dir noch was?" - User checked if anything was missing before starting implementation.
17. "Start implementation" - User requested to begin the implementation phase.]

[Technical Inventory:

• Weak Reference Finalizer: Discussed as a potential implementation.
• Namespace Analyzer: Mentioned for variable resolution and scope management.
• Import Handling: Addressed as a necessary component for the implementation.
• AST Model: Discussed in terms of memory management and necessity.
• Global Reference Management: Proposed to improve efficiency in handling references.
• Diagnostics and Unused Detection: Considered for future analysis phases.]

[Code Archaeology:

• No specific code files or functions were directly referenced in the recent exchanges, but the conversation revolved around concepts that would likely be implemented in code related to the namespace analyzer and language server.]

[Progress Assessment:

• Completed Tasks: Discussion of weak reference finalizer and its documentation.
• Partially Complete Work: Ongoing discussions about namespace handling, import management, and the need for regression tests.
• Validated Outcomes: None explicitly confirmed as working through testing.]

[Context Validation: All critical information for continuation is captured, including user requests for implementation, documentation, and clarification on various aspects of the project.]

[Recent Commands Analysis:

• Last Agent Commands: User requested to "Start implementation."
• Tool Results Summary: No specific tool results were generated as the conversation was primarily focused on planning and discussion.
• Pre-Summary State: The agent was actively discussing the implementation of various components of the namespace analyzer and language server.
• Operation Context: The user aimed to finalize the planning phase and begin implementation of the discussed features.]

1. Conversation Overview: - Primary Objectives: User requested the implementation of a weak reference finalizer, documentation of changes, and a commit message for recent modifications. The conversation evolved to cover namespace handling, import management, and the need for a global reference management system. - Session Context: The conversation flowed from initial inquiries about implementation to detailed discussions on various components necessary for the language server and namespace analyzer. - User Intent Evolution: The user transi...
