Jan 1, 2026January 2026 focused on delivering a faster, more secure BuildXL pipeline through EBPF-based sandboxing, cache optimization, and infrastructure hardening. Major outcomes include enabling the EBPF-based sandbox by default with concurrent processing of explicitly observed file accesses, introducing ExplicitlyReportedFileAccessProcessor, and tracing access() syscalls to improve observability. These changes reduce post-processing time on the critical path and simplify logging. In parallel, the cache replay path was optimized by avoiding unnecessary restricted-read checks, boosting lookup performance. Infrastructure improvements across build and test tooling enhanced stability and performance, including directory exclusions for Component Governance, improved input-tracker probing, asynchronous ADO runner configuration deserialization, and SBOM/package updates. Targeted fixes for AzureLinux3 symlink handling and QTest stability further reduced flakiness. Overall, these efforts deliver measurable business value by shortening CI cycles, improving reliability, and reducing operational noise while expanding toolchain capabilities.
