All notable changes to EngineScript will be documented in this file.

Changes are organized by date, with the most recent changes listed first.

• Added domain hash (sha256sum, first 8 hex chars) to db_name_suffix in vhost-install.sh to prevent silent database name collisions when long domain names are truncated to fit MariaDB's 64-character identifier limit. Added explicit regex validation of the hash output (^[0-9a-f]{8}$) to catch pipeline failures with a clear error message.
• Replaced the overly-broad suffix length guard (>= 64) with an exact-length check (!= 14) that precisely validates the expected suffix format: _<8-char-hash>_<RAND_CHAR4>.
• Added backtick rejection to validate_db_identifier() as defense-in-depth against SQL injection via backtick-quoted identifiers, guarding against future regex changes.
• Tightened database_user validation regex from ^[A-Za-z0-9_]+$ to ^[A-Za-z0-9]+$ to accurately reflect the RAND_CHAR16 source charset (a-zA-Z0-9, no underscores).
• Removed redundant single-quote and backslash sub-checks from database_password validation; these are already excluded by the ^[A-Za-z0-9_]+$ regex and were unnecessarily duplicated.
• Removed duplicate post-source validations of ${DB} and ${PSWD}; both values are fully validated pre-write before the credentials file is created, eliminating double validation.

• Removed invalid local keyword from create_db_sql declaration in scripts/functions/vhost/vhost-install.sh; local has no effect outside a function and was misleading.
• Removed invalid local keyword from SQL_ESCAPED_PSWD declaration in scripts/functions/vhost/vhost-install.sh for the same reason.
• Changed the printf -v create_db_sql format string from single quotes to double quotes (with backticks escaped as ```) to satisfy shell best-practice linting (SC2016 — expressions don't expand in single quotes).
• Replaced the IFS-manipulation subshell (IFS='|'; echo "${MULTIPART_PUBLIC_SUFFIXES[*]}") used to build MULTIPART_SUFFIX_CASE_PATTERN with a printf-based join (printf '%s|' + trailing-| strip), eliminating the HIGH-severity IFS side-effect security concern.

• Added explicit return statement at the end of escape_sql_string_literal() in scripts/functions/vhost/vhost-install.sh to satisfy shell best-practice linting (SC2151/explicit-return warning).
• Removed database_name and database_user lowercase normalizations from scripts/functions/vhost/vhost-install.sh; the random character sources (RAND_CHAR4 and RAND_CHAR16) are a-zA-Z0-9 and must not be altered, as normalization would corrupt generated identifiers.
• Updated validate_db_identifier regex from ^[a-z][a-z0-9_]*$ to ^[A-Za-z][A-Za-z0-9_]*$ to correctly accept mixed-case identifiers produced by RAND_CHAR4.
• Updated the pre-write database_user validation regex from ^[A-Za-z0-9_]+$ (already fixed from earlier lowercase-only pattern) to correctly reflect the RAND_CHAR16 charset (a-zA-Z0-9).
• Updated the post-source DB validation regex from ^[a-z][a-z0-9_]*$ to ^[A-Za-z][A-Za-z0-9_]*$ to match the mixed-case database name.
• Updated the pre-write database_password validation regex to ^[A-Za-z0-9_]+$, precisely matching the RAND_CHAR32 charset (a-zA-Z0-9_), replacing the prior broader pattern that excluded _ and would have incorrectly rejected valid generated passwords.
• Consolidated password validation to also reject single quotes and backslashes at the pre-write stage, eliminating a TOCTOU gap where a password could pass the first check but fail a later one.
• Added escape_sql_string_literal() helper function to safely escape MariaDB single-quoted string literals, guarding against SQL injection if password validation is ever bypassed.
• Used printf -v to prepare the CREATE DATABASE SQL statement separately before passing it to mariadb -e, reducing direct interpolation risk.
• Used escape_sql_string_literal on PSWD before interpolating into the CREATE USER SQL statement.

• Updated the single-zip database file detection in scripts/functions/vhost/vhost-import.sh to search for both *.sql and *.sql.gz patterns, so compressed database dumps are correctly found and imported instead of failing silently.
• Removed the duplicate URL_VALIDATION_REGEX argument from the prompt_input call for the Site URL field; validation is now handled exclusively by the subsequent validate_url function call, eliminating redundant logic.
• Added DB_CHARSET="${DB_CHARSET_VALIDATED}" after the charset case statement so DB_CHARSET is always the validated, lowercase value when used in the wp-config.php sed replacement, preventing a potential mismatch if the user supplies a mixed-case charset.
• Simplified run_url_search_replace_if_present to run wp search-replace directly with --report-changed-only, removing the preliminary wp db search pre-check that unnecessarily doubled full-table scans on large databases.
• Extracted WordPress salt generation into a new shared fetch_wp_salts() function in scripts/functions/shared/enginescript-shared-vhost.sh, replacing the divergent inline implementations in both vhost-install.sh and vhost-import.sh.
• fetch_wp_salts() retries up to 5 times with a 15-second delay between attempts, validates each response contains the expected define( content, and only hard-fails with a clear error message after all attempts are exhausted—preventing a transient WordPress.org API outage from permanently breaking a new install or import.

• Added explicit return statement at the end of run_url_search_replace_if_present in scripts/functions/vhost/vhost-import.sh to satisfy shell best-practice linting (SC2151/explicit-return warning).
• Removed redundant DOMAIN intermediate variable; SITE_URL is now assigned directly from SITE_URL_RAW via sed, eliminating the circular dependency pattern in scripts/functions/vhost/vhost-import.sh.
• Added clarifying comment to ORIGINAL_URL/NEW_URL assignments explaining that both variables are kept intentionally for search-replace workflows and may diverge in future modifications.
• Extracted the supported DB charset whitelist (utf8mb4, utf8, latin1) into a readonly ALLOWED_DB_CHARSETS array at the top of scripts/functions/vhost/vhost-import.sh, making it easier to update supported charsets in the future.
• Replaced the hardcoded case statement for charset validation with a loop over ALLOWED_DB_CHARSETS, so the error message dynamically reflects the authoritative list.
• Optimised the post-import search-replace step: added wp db search pre-checks before each wp search-replace call to skip full-table scans when the source URL (http:// or https://) is not present in the database, avoiding unnecessary work on large databases.
• Fixed the site-verification failure branch to use IMPORT_FORMAT == "two_file" instead of [[ -n "${WP_ARCHIVE_FILE}" ]] for format detection, consistent with the rest of the script.
• Removed a duplicate WordPress extraction block in scripts/functions/vhost/vhost-import.sh that re-ran archive extraction and wp-config path detection after those steps had already completed.
• Prevented a single-zip import failure path where the duplicate block referenced ${WP_ARCHIVE_FILE} (only populated in the two-file flow), which could trigger an unrecognized archive error.
• Kept the unified conditional extraction logic as the single source of truth for both single_zip and two_file import formats.
• Fixed the import start log message in scripts/functions/vhost/vhost-import.sh to conditionally reference SINGLE_ZIP_FILE for single_zip format, WP_ARCHIVE_FILE/DB_SOURCE_PATH for original format, or a generic fallback for other formats, instead of always referencing the empty WP_ARCHIVE_FILE.
• Removed leftover debug echo statements (DEBUG: Attempting to set prefix and DEBUG: sed command exit status for prefix) from production code in scripts/functions/vhost/vhost-import.sh.
• Added cleanup logic to move SINGLE_ZIP_FILE to BACKUP_DIR when IMPORT_FORMAT is single_zip, matching the existing two-file cleanup behaviour.
• Fixed the site-verification failure message to reference SINGLE_ZIP_FILE instead of DB_SOURCE_PATH when WP_ARCHIVE_FILE is unset, correctly identifying the original import file for single_zip imports.

• Removed obsolete and irrelevant MIME mappings from config/etc/nginx/globals/mime-types.conf for legacy Java Web Start, legacy package formats, and obsolete browser component types.
• Kept modern MIME coverage for WordPress-hosted assets while trimming project-irrelevant legacy entries.
• Updated config/etc/nginx/globals/compression-gzip.conf and config/etc/nginx/globals/compression-brotli.conf to remove deprecated compression MIME aliases and legacy dead types.
• Aligned gzip and brotli compression type lists to prioritize modern text-based and web-relevant content types.

• Updated the logic across the codebase to better optimize the server for a variety of configuration scenarios, including low an high memory environments.

Rolled out the DEBUG_INSTALL=1 debug feature uniformly across every install and update script that was missing it. When DEBUG_INSTALL=1 is set in enginescript-install-options.txt, each script now:

• Added explanatory comment in scripts/install/tools/frontend/admin-control-panel-install.sh clarifying that the {FONTAWESOME_VER} placeholder only appears in index.html, so its substitution is intentionally scoped to that file rather than included in the multi-file loop.
• Fixed sed range command used to remove the Adminer tool card (adminer-tool div) when INSTALL_ADMINER=0. Changed {1d;$d;} to d so the command deletes all lines in the matching range, not only the first and last lines of the range.

• Created placeholder page (config/var/www/placeholder/index.html) for non-WordPress domains.
  • Dark-themed, responsive design matching EngineScript admin dashboard color scheme.
  • Includes links to EngineScript website, GitHub repository, and documentation wiki.

  • Without WordPress: Nginx vhost, SSL certificates, directories, logs, permissions, and placeholder page only. No database or CMS created.
  • Shared infrastructure steps (Cloudflare API, nginx vhost, SSL, backup directories, site root, domain logs) run for both installation paths.
  • Non-WordPress path displays a summary with site root, vhost, SSL, and backup locations.

• Updated all EngineScript references to use EngineScript Site Optimizer.
• Updated repository links and release download URLs to use EngineScript/enginescript-site-optimizer.

• Updated repository links and release download URLs to use EngineScript/enginescript-site-exporter.
• Normalized legacy Site Exporter naming from SSE/sse-* to ES_SE and es-se across workflow variables, temp paths, and script comments.

• Added ZLIB_IMPLEMENTATION option to config/home/enginescript-install-options.txt:
  • "" (empty/default) = standard zlib (no change from current behavior)
  • "zlib-ng" = zlib-ng, a high-performance C drop-in replacement using --zlib-compat mode
  • "zlib-rs" = zlib-rs, a Rust-based implementation (requires cargo/rustc on the server)
• Added ZLIB_NG_VER and ZLIB_RS_VER to enginescript-variables.txt for centralized version management.
• Updated scripts/install/zlib/zlib-install.sh: Now prepares the selected zlib alternative alongside the standard zlib download. Handles zlib-ng configure wrapper, stub Makefile (for nginx distclean compatibility), and zlib-rs cargo build + prefix install.
• Updated scripts/install/nginx/nginx-compile.sh: Dynamically sets --with-zlib flags or include/link paths based on ZLIB_IMPLEMENTATION. Appends a build tag (-zlibng or -zlibrs) to the nginx --build string for identification.

  • Removed commented-out Cloudflare zlib clone/configure block and zlib-ng block from zlib-install.sh.
  • Removed ZLIB-Cloudflare entry from README.md software table.
  • Official zlib (madler/zlib) remains in use for Nginx compilation.

• Added 8 new shared functions to scripts/functions/shared/enginescript-common.sh:
  • validate_not_placeholder() — Validates config variables are not still set to PLACEHOLDER; exits with warning directing user to es.config.
  • run_install_step() — Idempotent install step runner: checks completion flag, executes script with error logging, marks done, and calls debug_pause.
  • verify_service_running() — Checks systemd service status after installation, logs completion flag, exits on failure.
  • clean_directory() — Removes a directory if it exists (clean before fresh install).
  • download_and_extract() — Downloads a tarball with wget and extracts with tar in one call.
  • print_install_banner() — Prints formatted installation completion banner with configurable sleep.
  • git_clone_fresh() — Removes existing directory and clones a git repository fresh.

• Jetpack Boost static delivery fallback fix: Added a dedicated Nginx location for /wp-content/boost-cache/static/*.css|*.js that uses try_files with fallback to /index.php?$args.
  • Existing concatenated files continue to be served directly by Nginx.
  • Missing concatenated files now route through WordPress instead of returning an Nginx-native 404.
  • Restores compatibility with Jetpack Boost enhanced delivery detection that relies on WordPress is_404() behavior in wp-content paths.
• Generic CSS/JS location clarified: Added inline guidance noting why try_files is intentionally not enabled in the general \.(css|js) location to preserve fast native 404 handling for non-Jetpack asset misses.
