wp dbcommands currently require themysql/mariadbCLI binary, causing failures with drop-in database engines (HyperDB, custom drivers) or environments where the binary simply isn't installed. This PR adds automatic fallback to WordPress's$wpdbfor all relevant commands.Changes
src/DB_Command.phpis_mysql_binary_available()— probes for the mysql/mariadb binary via/usr/bin/env <binary> --version; result is statically cachedmaybe_load_wpdb()— loads the minimal WordPress files needed for$wpdb(load.php,compat.php,plugin.php,functions.php,class-wpdb.php), includes anywp-content/db.phpdrop-in (HyperDB et al.), and falls back to creating a plainwpdbinstance with wp-config.php credentials +$table_prefixrun_query()— now checks binary availability at the top and, when absent, routes throughmaybe_load_wpdb()+$wpdb->query()instead of invoking the mysql CLI. This coversdropandreset.query()— after the existing SQLite branch, checks binary availability and routes to the new wpdb path when absent viawpdb_query()wpdb_query()— executes arbitrary SQL via$wpdb; mirrors the mysql-path behaviour (row-count reporting for DML, formatted tabular output for SELECT,--skip-column-namessupport)import()— when the mysql binary is unavailable, reads the SQL file (or STDIN) and delegates towpdb_import()wpdb_import()— executes a SQL dump through$wpdbstatement-by-statement, applying the sameautocommit=0 / unique_checks=0 / foreign_key_checks=0 … COMMIToptimizations as the mysql path (unless--skip-optimizationis passed)split_sql_statements()— splits a SQL string into individual statements using a state-machine parser that correctly handles single-quoted strings, double-quoted strings,--line comments, and/* */block commentsfeatures/db-query.featureAdded a
