Month: 2026-07 — Summary of developer work on unsloth: Implemented robust llama-server load progress reporting and health diagnostics to improve reliability and operational visibility. Key feature delivered: report complete load when llama-server is healthy, irrespective of resident set size; introduced a per-process VmRSS high-water mark to prevent misleading progress during model loading when -ngl offloads weights; enhanced health-check error messaging to provide actionable diagnostics. The changes are anchored by the primary commit abdc968e8d7ec82cab3349a5ae7edf5c41936ab4, which refines load_progress(), handles VRAM offload edge cases, preserves VmRSS semantics, and includes test and CI hygiene improvements (pre-commit fixes). Impact: faster, more predictable startup and health reporting, reducing deployment risk and operator triage time; clearer diagnostics drive quicker remediation and better uptime. Technologies/skills demonstrated: systems instrumentation (VmRSS tracking), robust testing with isolated test stubs for heavy dependencies, Pythonized load logic, and CI/pre-commit discipline.
