This commit introduces a comprehensive tracing mechanism for allocation failures within the Adaptive Cache Engine (ACE) component. This feature allows for precise identification of the root cause for Out-Of-Memory (OOM) issues related to ACE allocations. Key changes include: - **ACE Tracing Implementation**: - Added environment variable to enable/disable detailed logging of allocation failures. - Instrumented , , and to distinguish between "Threshold" (size class mismatch), "Exhaustion" (pool depletion), and "MapFail" (OS memory allocation failure). - **Build System Fixes**: - Corrected to ensure is properly linked into , resolving an error. - **LD_PRELOAD Wrapper Adjustments**: - Investigated and understood the wrapper's behavior under , particularly its interaction with and checks. - Enabled debugging flags for environment to prevent unintended fallbacks to 's for non-tiny allocations, allowing comprehensive testing of the allocator. - **Debugging & Verification**: - Introduced temporary verbose logging to pinpoint execution flow issues within interception and routing. These temporary logs have been removed. - Created to facilitate testing of the tracing features. This feature will significantly aid in diagnosing and resolving allocation-related OOM issues in by providing clear insights into the failure pathways.
