From 870691e3d4854b1c226d5880e9f6961868ee0467 Mon Sep 17 00:00:00 2001 From: Max Date: Thu, 20 Nov 2025 12:12:29 +0800 Subject: [PATCH] Implement trace archiving and management features - Added functionality to archive traces by compressing and marking them as read-only, enhancing data management capabilities. - Introduced methods for checking if a trace is archived and for unarchiving traces, allowing for better control over trace data. - Updated the trace manager and driver interfaces to support archiving operations, ensuring consistency across components. - Enhanced error handling for operations on archived traces, preventing modifications to read-only data. - Improved trace metadata structure to include archived status and timestamp, facilitating better trace lifecycle management. --- agent/context/context.go | 2 +- trace/local/driver.go | 303 +++++++++++++++++++++++++++++++++++- trace/manager.go | 21 ++- trace/store/driver.go | 296
