xin zhuang abc8c6dadf fix(wasm): preserve leading BOM in custom section names (#2102) 2026-10-12 18:39:01 +08:00
Vinícius Andrade 1febc22907 fix(wasm): inspect modules whose custom section names contain NUL (#1981)
* fix(wasm): frame custom section names at their displayed NUL

wasm-objdump prints a custom section name with printf's %.*s, so an
embedded NUL ends the displayed name, as it does for module names.
The section row was compared with the complete name decoded from WAT,
so a valid module whose custom section name contains U+0000 failed
inspection with "WABT custom-section header does not match decoded
WAT". Compare the row with the displayed prefix instead.

* test(wasm): cover NUL-terminated custom section names

Frame the real objdump golden with a decoded custom section name that
continues after a NUL, and keep rejecting a displayed prefix that
differs from the decoded name.

* test(wasm): verify a NUL-containing custom section name with real WABT

Add a custom section named "visible\0hidden" to the real-tool custom
name fixture. WABT 1.0.42 decodes it as an escaped WAT name and
displays "visible" in wasm-objdump, so the verifier expects that
description through the compiled CLI and MCP.

* refactor(wasm): share WABT's NUL-terminated name display

Module-name preamble lines and custom-section rows each truncated the
decoded name at its first NUL. Keep that display rule in one helper so
both framings follow the same producer behavior. Output is unchanged.
