Four shell correctness and security issues in scripts/functions/vhost/vhost-install.sh.

Software Version Updates

N/A — shell script correctness and security fixes only.

Changed Versions

No version changes.

Version Diff

- local create_db_sql
  printf -v create_db_sql 'CREATE DATABASE `%s` ...' "${DB}"

+ printf -v create_db_sql "CREATE DATABASE \`%s\` ..." "${DB}"

- local SQL_ESCAPED_PSWD
  SQL_ESCAPED_PSWD="$(escape_sql_string_literal "${PSWD}")"

- MULTIPART_SUFFIX_CASE_PATTERN="$(IFS='|'; echo "${MULTIPART_PUBLIC_SUFFIXES[*]}")"
+ MULTIPART_SUFFIX_CASE_PATTERN="$(printf '%s|' "${MULTIPART_PUBLIC_SUFFIXES[@]}")"
+ MULTIPART_SUFFIX_CASE_PATTERN="${MULTIPART_SUFFIX_CASE_PATTERN%|}"

Verification Checklist

  • local keyword no longer used outside function scope
  • printf -v format string uses double quotes; backtick identifiers escaped correctly as \`
  • MULTIPART_SUFFIX_CASE_PATTERN built without IFS mutation — no word-splitting side-effects
  • No syntax errors in modified script

Notes

  • local outside functions (×2): local create_db_sql and local SQL_ESCAPED_PSWD appeared at script body level where local is a no-op. Both declarations removed; variables are written directly.
  • Single-quoted printf format string (SC2016): format string switched to double quotes with escaped backticks (```) so the quoting style is consistent and the linter warning is resolved.
  • IFS manipulation (HIGH): $(IFS='|'; ...) replaced with printf '%s|' "${array[@]}" + ${var%|} trim — joins array elements with | without touching IFS.

Pull request overview

This PR tightens shell correctness in the vhost installation flow (vhost-install.sh) by removing invalid local usage in the script body, adjusting SQL statement construction, and avoiding IFS-based array joining; it also documents these updates in the project changelog.

Changes:

  • Build MULTIPART_SUFFIX_CASE_PATTERN via printf + trailing separator trim rather than an IFS-based join.
  • Remove local declarations that were placed outside function scope and therefore ineffective.
  • Adjust printf -v SQL format-string quoting for CREATE DATABASE and record the changes in CHANGELOG.md.

File Description
scripts/functions/vhost/vhost-install.sh Removes invalid local usage, updates SQL string construction, and changes how multipart suffix patterns are built.
