CHANGELOG

2.4 (2026-06-06) -- security & robustness hardening
-- per-call SCWS instance via scws_fork(); removed global ParserState (fixes
   token corruption with SRFs / nested parser calls within one backend)
-- _PG_init() now registers GUCs once at module load; init failures no longer
   permanently break the backend
-- whitelist validation for zhparser.extra_dicts entries (only [A-Za-z0-9_.-],
   .txt or .xdb); rejected by check_hook
-- refuse to write per-database custom dict files when current_database()
   contains characters unsafe for filesystem paths
-- sync_zhprs_custom_word() now builds COPY via format() / %L and validates
   the database name (mitigates dynamic-SQL pitfalls)
-- fix lexeme attr range: was ['a','x'] which silently dropped 'y' (modal)
   and 'z' (status); now ['a','z']
-- safer pstrdup namespace handling in zhparser.h (no longer permanently
   shadows the PG macro)
-- backup-custom-dict.sh: set -euo pipefail, dry-run, --yes confirmation,
   safe globbing
-- Makefile: pkg-config detection for SCWS, -Wformat-security
-- new GitHub Actions matrix CI for PG 16/17/18
-- new regress/ container (Dockerfile + entrypoint + wrapper) and
   sql/zhparser_hardening.sql; pg_regress green on PG 16/17/18
