MariaDB connector/node.js 2.5.0

This version is a minor correction release (Stable (GA)).

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
• CONJS-144 - TypeScript type ssl wrong definitions
• CONJS-143 - Array parameter escaping differ from mysql/mysql2
• CONJS-133 - Support ES2020 BigInt object (option supportBigInt)
• CONJS-77 - Support MySQL caching_sha256_password authentication
• CONJS-76 - Support MySQL sha256_password authentication

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.

MariaDB connector/node.js 2.2.0

This version is a Stable (GA) release.

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.

example:

//query that takes more than 20s
connection
  .query({sql: 'information_schema.tables, information_schema.tables as t2', timeout: 100 })
  .then(...)
  .catch(err => {
          // SQLError: (conn=2987, no: 1969, SQLState: 70100) Query execution was interrupted (max_statement_time exceeded)
          // sql: select * from information_schema.columns as c1, information_schema.tables, information_schema.tables as t2 - parameters:[]
          // at Object.module.exports.createError (C:\projets\mariadb-connector-nodejs.git\lib\misc\errors.js:55:10)
          // at PacketNodeEncoded.readError (C:\projets\mariadb-connector-nodejs.git\lib\io\packet.js:510:19)
          // at Query.readResponsePacket (C:\projets\mariadb-connector-nodejs.git\lib\cmd\resultset.js:46:28)
          // at PacketInputStream.receivePacketBasic (C:\projets\mariadb-connector-nodejs.git\lib\io\packet-input-stream.js:104:9)
          // at PacketInputStream.onData (C:\projets\mariadb-connector-nodejs.git\lib\io\packet-input-stream.js:160:20)
          // at Socket.emit (events.js:210:5)
          // at addChunk (_stream_readable.js:309:12)
          // at readableAddChunk (_stream_readable.js:290:11)
          // at Socket.Readable.push (_stream_readable.js:224:10)
          // at TCP.onStreamRead (internal/stream_base_commons.js:182:23) {
          //     fatal: true,
          //         errno: 1969,
          //         sqlState: '70100',
          //         code: 'ER_STATEMENT_TIMEOUT'
          // }
  });

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
