fix(refactor/node/handle-callback-err): reject invalid regex config by camc314 · Pull Request #23740 · oxc-project/oxc

camc314 · 2026-06-23T10:48:21Z

Reject invalid caret-prefixed node/handle-callback-err patterns during configuration parsing instead of falling back to literal string matching.

^-prefixed options are documented as regex patterns, so malformed regex input should surface as a config error.

Part of #23594

Note

Copilot was unable to run its full agentic suite in this review.

Tightens configuration parsing for the handle-callback-err rule by rejecting invalid regex patterns instead of silently treating them as plain strings.

Changes:

Import serde’s de::Error trait to enable custom deserialization errors.
Change deserialization to return a structured error on invalid regex compilation.
Update docs to state invalid regex patterns are rejected during config parsing.
