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.onData (C:\projets\mariadb-connector-nodejs.git\lib\io\packet-input-stream.js:160:20)
          // at Socket.emit (events.js:210:5)

          // 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
• dependencies update

• [CONJS-57] Multiple alternative authentication methods for the same user (MariaDB 10.4)
• [CONJS-61] Permit handling expired password
• [CONJS-85] Implement pool events according to mysql/mysql2 API
• [CONJS-87] Array parameter automatic conversion
• [CONJS-89] Performance improvement on decoding string
• [CONJS-88] Charset collation option separation
• [CONJS-74] Types definition must be string, not byte when using option typeCast

New Options

option	description	type	default
collation	(used in replacement of charset) Permit to defined collation used for connection. This will defined the charset encoding used for exchanges with database and defines the order used when comparing strings. It's mainly used for micro-optimizations	string	UTF8MB4_UNICODE_CI
permitConnectionWhenExpired	Permit a user with expired password to connect. Only possible operation in this case will be to change password ('SET PASSWORD=PASSWORD('XXX')')	boolean	false

The option charset now corresponds to charset, still permitting collation for compatibility, but then a warning is thrown to console.

MariaDB connector/node.js 2.0.5

This version is a Stable (GA) release.

Changelog

• CONJS-71 TypeScript definition is not exported

MariaDB connector/node.js 2.0.4

This version is a Stable (GA) release.

Changelog

• [CONJS-69] permit set numeric parameter bigger than javascript 2^53-1 limitation
• [CONJS-68] error when reading datetime data and timezone option is set
• [CONJS-58] parse Query when receiving LOAD LOCAL INFILE, to prevent man in the middle attack

• [CONJS-64] handle Error packet during resultset to permit query timeout with SET STATEMENT max_statement_time= FOR
• [CONJS-66] SET datatype handling (returning array)
• [CONJS-67] Changing user does not takes in account connector internal state (transaction status)

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.

• [CONJS-59] pool now throw ER_ACCESS_DENIED_ERROR in place of a basic timeout error
• [CONJS-60] handling pipe error for a stream, avoiding hang in case of pipe error.
• [CONJS-55] Connector throw an error when using incompatible options
