Rene Cannao eb0e6b0657 feat: add PgBouncer config converter, CLI tool, and SHOW commands (Stages 2+3) (#5564 , #5565 ) Stage 2 - Config Converter + CLI: - PgBouncer_ConfigConverter: Converts parsed PgBouncer config into ProxySQL SQL statements with full parameter mapping - Databases → pgsql_servers + pgsql_query_rules (auto hostgroup assignment) - Multi-host entries → multiple server rows with equal weight - Users → pgsql_users with pool mode mapping (session→fast_forward, transaction→transaction_persistent, statement→defaults) - Globals → pgsql-* variables with unit conversion (s→ms) - HBA rules → pgsql_firewall_whitelist entries - Strict mode (default): fails on unmappable parameters - Relaxed mode (--ignore-warnings): warns and continues - Dry-run output: commented SQL with summary - ProxySQL_CLI: Entry point for proxysql-cli binary (argv[0] detection) - Subcommand: import-pgbouncer <path> [--dry-run] [--ignore-warnings] - Never starts daemon, always exits after command - 39 unit tests covering: minimal conversion, multi-host, wildcard database, pool mode mapping, global settings, strict/relaxed modes, query rules, dry-run format, TLS settings Stage 3 - PgBouncer-Compatible SHOW Commands: - PgBouncer_ShowCommands: Translates PgBouncer SHOW commands to equivalent ProxySQL SQL queries with exact column output format - SHOW POOLS, STATS, SERVERS, CLIENTS, DATABASES, USERS, CONFIG, VERSION, STATE, LISTS - SHOW EXTENDED variant adds ProxySQL-specific columns - Unsupported commands (DNS_HOSTS, PEERS, etc.) return clear errors - Case-insensitive, handles trailing semicolons and extra whitespace - 39 unit tests covering: command recognition, case insensitivity, trailing semicolons, EXTENDED variant, SQL output columns, non-matching queries, unsupported commands		5 days ago

Folder structure

tap: Contains TAP helper library for testing, and general utilities used across all tests.
tests: General test folder for either unitary or functional tests.
tests_with_deps: Test folder that holds all the tests that require special dependencies for being build.
tests_grp_*: tap test groups of specific tests with special configs applied via
- pre-tests_grp_*.bash script run before tests
- pre-tests_grp_*.sql script run before tests
- post-tests_grp_*.bash script run after tests
- post-tests_grp_*.sql script run after tests

example test group tests_grp_mytests can be created by

TG='mytests'
mkdir -p test/tap/tests_grp_$TG
cd test/tap/tests_grp_$TG
for T in $(ls -1 ../tests/); do ln -fsT ../tests/$T $T; done
cat > pre-test_grp_$TG-proxysql.sql << EOF
# run this test group with:
SET mysql-multiplexing='false';
LOAD MYSQL VARIABLES TO RUNTIME;
SAVE MYSQL VARIABLES TO DISK;
EOF
