MariaDB connector/j 1.8.0

This version is a general availability (GA) release for java 7+

Changelog

Evolutions

• [CONJ-675] permit multiple alternative authentication methods for the same user (future MariaDB 10.4 feature)
• {CONJ-678] permit indication of truststore/keystore type (JKS/PKCS12), then not relying on java default type
• [CONJ-378] GSSAPI: client can provide SPN
• [CONJ-667] Support MYSQL_TYPE_JSON datatype
• [CONJ-652] faster results buffering socket available
• [CONJ-659] improve text performance reading date/time/timestamp resultset
• [CONJ-670] ability to Refresh SSL certificate

New options:

Option	Description
useReadAheadInput	use a buffered inputSteam that read socket available data. Default: true
keyStoreType	indicate key store type (JKS/PKCS12). default is null, then using java default type.
trustStoreType	indicate trust store type (JKS/PKCS12). default is null, then using java default type
servicePrincipalName	when using GSSAPI authentication, SPN (Service Principal Name) use the server SPN information. When set, connector will use this value, ignoring server information
includeInnodbStatusInDeadlockExceptions	add "SHOW ENGINE INNODB STATUS" result to exception trace when having a deadlock exception. Default: false
includeThreadDumpInDeadlockExceptions	add thread dump to exception trace when having a deadlock exception. Default: false

CONJ-642 disable the option "useBulkStmts" by default

Using useBulkStmts permit faster batch, but cause one major issue: Batch return -1 = SUCCESS_NO_INFO

Different option uses this information for optimistic update, and cannot confirm if update succeeds or not.
This option still makes sense, since for big batch is way faster, but will not be activated by default.

Minor changes

• [CONJ-628] optimization to read metadata faster
• [CONJ-637] java.sql.Driver class implement DriverPropertyInfo[] getPropertyInfo, permitting listing options on querying tools
• [CONJ-641] update maven test dependencies for java 10 compatibility
• [CONJ-643] PreparedStatement::getParameterMetaData always returns VARSTRING as type resulting in downstream libraries interpreting values wrongly
• [CONJ-623] Increase connection logging when Primary node connection fails
• [CONJ-384] Add option permit having "affected" or "found" rows

Bugfixes

• [CONJ-646] possible NullPointerException when connection lost to database using aurora configuration with one node
• [CONJ-672] batch using multi-send can hang when using query timeout
• [CONJ-544] disable SSL session resumption when using SSL
• [CONJ-589] correcting Clob.length() for utf8mb4
• [CONJ-649] datasource connectTimeout URL parameter is not honoured
• [CONJ-650] Correction on resultset.getObject(columnName, byte[].class) when value is NULL
• [CONJ-665] old MySQL (<5.5.3) doesn't support utf8mb4, using utf8 on 3 bytes as connection charset by default
• [CONJ-671] MariaDb bulk threads occupy full cpu(99%) while db connections broken
• [CONJ-673] abording a connection while fetching a query still does read whole resultset
• [CONJ-669] SQLSyntaxErrorException when querying on empty column name
• [CONJ-674] make dumpQueriesOnException = false by default as per documentation
• [CONJ-616] correction on possible NPE on getConnection when using failover configuration and master is down, not throwing a proper exception
• [CONJ-636] Error in batch might throw a NPE and not the proper Exception
• [CONJ-624] MariaDbPoolDataSource possible NPE on configuration getter
• [CONJ-622] The option "connectTimeout" must take in account DriverManager.getLoginTimeout() when set
• [CONJ-621] wrong escaping when having curly bracket in table/field name
• [CONJ-618] Client preparestatement parsing error on escaped ' / " in query
  minor:
• [CONJ-644] small optimization when validating galera connection
• [CONJ-625] add coverage test
• [CONJ-654] DatabaseMetaData.getDriverName() returns connector/J with a lowercase c
