}
prepare.close();

Issues Fixed

  • CONJS-223 Metadata column name gets sporadic corrupted
  • CONJS-211 Session timezone unset on connection re-use with connection pool
  • CONJS-212 when throwing an error when using option leakDetectionTimeout, might result in throwing wrong error with Cannot read properties of null (reading 'leaked')
  • CONJS-217 caching_sha2_password never succeed using FAST AUTHENTICATION. With correction, one less exchanges is done when connecting to a MySQL server
  • CONJS-219 prepare cache was not limited to prepareCacheLength but can increase up to 2x the prepareCacheLength value, leading to possible ER_MAX_PREPARED_STMT_COUNT_REACHED

3.0.1 (Jul 2022)

Full Changelog

Notable changes

  • Error description improvement
    • Pool might return a common error ‘retrieve connection from pool timeout after XXXms’ in place of real error.[CONJS-200]
    • [CONJS-209] Trace option now works when using pool/cluster. It is recommended to activate the trace option in development Since driver is asynchronous, enabling this option to save initial stack when calling any driver methods. This allows having the caller method and line in the error stack, permitting error easy debugging. The problem is this error stack is created using Error.captureStackTrace that is very very slow. To give an idea, this slows down by 10% a query like 'select * from mysql.user LIMIT 1', so not recommended in production. 
      const pool = mariadb.createPool({
host: 'mydb.com',
user: 'myUser',
connectionLimit: 5,
trace: true
});
await pool.query('wrong query');
/* will throw an error like :
  SqlError: (conn:15868, no: 1064, SQLState: 42000) You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'wrong query' at line 1
    sql: wrong query - parameters:[]
      at Object.module.exports.createError (errors.js:57:10)
      at ...
    From event:
      at Function._PARAM (\integration\test-pool.js:60:18)
      at …
    text: "You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'wrong query' at line 1",
    sql: 'wrong query - parameters:[]',
    fatal: false,
    errno: 1064,
    sqlState: '42000',
    code: 'ER_PARSE_ERROR'
*/
    • Pool error description is improved indicating pool information, like [CONJS-208]: 
      SqlError: (conn:-1, no: 45028, SQLState: HY000) retrieve connection from pool timeout after 200ms
  (pool connections: active=1 idle=0 limit=1)
  at Object.module.exports.createError
  …
  • node.js 18 supported [CONJS-197]
  • New option checkNumberRange. When used in conjunction of decimalAsNumber, insertIdAsNumber or bigIntAsNumber, if conversion to number is not exact, connector will throw an error [CONJS-198]. This permits easier compatibility with mysql/mysql2 and 2.x version driver version.
  • Performance enhancement for multi-rows resultset. Internal benchmarks show improved performance by 10% for a result-set of 1000 rows.[CONJS-210]

Issues Fixed

  • Wrong error returned "Cannot read properties of undefined… … (reading 'charset')" when error during handshake [CONJS-193]
  • [CONJS-194] Charset change using parameterized query fails with "Uncaught TypeError: opts.emit is not a function"
  • [CONJS-195] Error "cannot mix BigInt and other types" when parsing negative bigint
  • [CONJS-196] connection.close() is now really an alias or connection.release()
  • [CONJS-199] wrong return type for batch() on typescript
  • [CONJS-201] typecast geometry parsing error
  • [CONJS-202] support pre 4.1 error format for 'too many connection' error
  • [CONJS-203] encoding error for connection attributes when using changeUser with connection attributes
  • [CONJS-206] possible race condition on connection destroy when no other connection can be created
  • [CONJS-204] handle password array when using authentication plugin “pam_use_cleartext_plugin”
  • [CONJS-205] query hanging when using batch with option timeout in place of error thrown

3.0.0 (Jan 2022)

Full Changelog

  • CONJS-149 - [CONJS-149] correcting possible TypeError [ERR_UNKNOWN_ENCODING], Node v15 compatibility

2.5.0 (15 Oct 2020)

Full Changelog

  • CONJS-148 - permit setting socket keep alive (option keepAliveDelay)
  • CONJS-145 - batch rewrite error when packet reach maxAllowedPacket
  • CONJS-146 - Using callback API, batch, avoid return error if connection not established

New Options

option description type default
arrayParenthesis Indicate if array are included in parenthesis. This option permit compatibility with version < 2.5 boolean false
rsaPublicKey Indicate path/content to MySQL server RSA public key. use requires Node.js v11.6+ string
cachingRsaPublicKey Indicate path/content to MySQL server caching RSA public key. use requires Node.js v11.6+ string
allowPublicKeyRetrieval Indicate that if rsaPublicKey or cachingRsaPublicKey public key are not provided, if client can ask server to send public key. boolean false
supportBigInt Whether resultset should return javascript ES2020 BigInt for BIGINT data type. This ensures having expected value even for value > 2^53 (see safe range). boolean false
keepAliveDelay permit to enable socket keep alive, setting delay. 0 means not enabled. Keep in mind that this don't reset server @@wait_timeout (use pool option idleTimeout for that). in ms int

CONJS-143 is a breaking change. Queries that have a IN parameter with array parameters format change. previous format did not accept parenthesis :

conn.query('SELECT * FROM arrayParam WHERE id = ? AND val IN ?', [1, ['b', 'c']]);

now, format is

conn.query('SELECT * FROM arrayParam WHERE id = ? AND val IN (?)', [1, ['b', 'c']]);

same than mysql/mysql2 drivers. previous behaviour can be reverted setting option arrayParenthesis to true.

2.2.0 (03 Feb. 2020)

Full Changelog

CONJS-119 Add an option to detect Server version using a dedicated SELECT @@version
Azure is using a proxy that will return a MySQL handshake not reflecting real server.
A new option `forceVersionCheck` is added to permit issuing a new `SELECT @@Version` command on connection creation, 
to retrieve the correct server version. Connector will then act according to that server version.
CONJS-20 add query timeout implementation
This option is only permitted for MariaDB server >= 10.1.2, and permits to set a timeout to query operation. 
Driver internally use `SET STATEMENT max_statement_time=<timeout> FOR <command>` permitting to cancel operation when timeout is reached, 

Implementation of max_statement_time is engine dependent, so there might be some differences: For example, with Galera engine, a commits will ensure replication to other nodes to be done, possibly then exceeded timeout, to ensure proper server state.
CONJS-110 fast-authentication improvement:
  * add mysql_native_password to fast-authentication path
  * plugin 'mysql_native_password' is used by default if default server plugin is unknown
  * unexpected packet type during handshake result will throw a good error.
CONJS-117 Implement a pool leak detection
A new option `leakDetection` permits to indicate a timeout to log connection borrowed from pool.
When a connection is borrowed from pool and this timeout is reached, a message will be logged to console indicating a possible connection leak.
Another message will tell if the possible logged leak has been released.
A value of 0 (default) meaning Leak detection is disable   
Additionally, some error messages have improved:
- Connection timeout now indicate that this correspond to socket failing to establish
- differentiate timeout error when closing pool to standard connection retrieving timeout

misc:

  • CONJS-120 Permit values in SQL object to permits compatibility with mysql/mysql2
  • CONJS-118 missing import for Error when asking for connection when pool is closed. Thanks to @WayneMDB
  • correcting typescript import of @types/node to version >8 thanks to @SimonSchick

Pool improvement

New Options

option description type default
idleTimeout Indicate idle time after which a pool connection is released. Value must be lower than @@wait_timeout. In seconds (0 means never release) integer 1800
minimumIdle Permit to set a minimum number of connection in pool. Recommendation is to use fixed pool, so not setting this value. integer set to connectionLimit value

This permits to set a minimum pool size, meaning that after a period of inactivity, pool will decrease inner number of connection to a minimum number of connection (defined with minimumIdle). By default, connections not used after idleTimeout (default to 30 minutes) will be discarded, avoiding reaching server @@wait_timeout.

Pool handle connection creation automatically, with now some delayed after failing to establish a connection, to avoid using CPU unnecessary. Authentication error in pool have now a better handling.
