From 251443ccb492ccdb2bab3aa0e3a04f343bef2410 Mon Sep 17 00:00:00 2001 From: Juliano Martinez Date: Sun, 21 Jun 2026 23:47:13 +0200 Subject: [PATCH] Bound emitter output growth before allocation The emitter previously enforced max_output_bytes only after building the complete output buffer. That meant callers could still hit allocator growth, or writer APIs could allocate the full output, before the configured safety limit returned error.Unsupported. Add an internal OutputBuffer wrapper that checks the configured output byte budget before every append. The existing block, flow, scalar, and tag emitter helpers now accept the checked output buffer shape, while their unit tests can still pass ordinary ArrayList buffers. When the checked buffer trips the budget, emit maps that internal allocation-shaped failure back to ParseError.Unsupported. Add a regression using a FixedBufferAllocator and an oversized scalar so the test fails with OutOfMemory on the old behavior and passes only when the output limit is checked before buffer growth. Also align the default coverage threshold with CI by changing plain zig build coverage to default to 85 percent instead of 100 percent, and extend the structure test to keep build.zig and CI in sync.
