0.3.18

New Features

• Windows builds are restored following an extensive dive into DLL and compiler issues.
• MySQL Connector/C 6.1.5 is now vendored into the binary gems for Windows.

Changes

0.2.24

See https://github.com/brianmario/mysql2/releases/0.3.17

0.3.17

New Features

• Microseconds are now supported in a TIME field (0.3.12 added support for msec in DATETIME).

Bugfixes

• Use /dev/null in invalidate_fd to avoid infinite loop in OpenSSL.
• Change sql_state to attr_reader to avoid Ruby warning.

Changes

• Added call to mysql_library_init during initialization of the gem for thread safety.
• State the name of the field that contains a bad datetime value in the exception.
• Travis CI updates including:
  • SSL tests
  • Ruby 2.1.x
  • Newer Rubinius 2.x
  • OS X with Ruby 2.0
  • MySQL 5.7 with Ruby 2.0

0.3.16

New Features

• New connection argument :init_command sets a query string to run at connect/reconnect.

Bugfixes

• Check that dir_config returns at least one valid directory at compile time.

Changes

• Enforce connection retry time limits across interrupts (e.g. by signals, etc.)
• Prevent MySQL from calling shutdown() on shared sockets.
• MariaDB 5.5 and 10.0 added to the test suite. No changes were required to support MariaDB, but we're actively testing for compatibility now.
• Update specs for Ruby 2.1 Timeout behavior.

0.2.23

See https://github.com/brianmario/mysql2/releases/0.3.16

0.3.12

New features

• We're compatible with Ruby 2.0.0 now!
• A new :streaming option can be passed while issuing a query which will leave the results on the server side and stream them to the client a row-at-a-time. This is great for really large datasets.
• Mysql2::Client#abandon_results! has been introduced which lets you throw away result sets in an efficient manner.
• Mysql2::Client#select_db has been introduced allowing you to select which database a connection is using without needing to issue a query.
• Mysql2::Client#more_results? has been introduced which is used to check if there are more results to be read when CLIENT_MULTI_STATEMENTS is enabled.
• Mysql2::Client#next_result has been introduced which is used to step the result cursor forward by one when CLIENT_MULTI_STATEMENTS is enabled.
• Mysql2::Client#store_result has been introduced which allows you to read the next result off the wire when CLIENT_MULTI_STATEMENTS is enabled.
• Mysql2::Client#reconnect= has been introduced which allows you to change the reconnect behavior of libmysql while a connection is active.
• Mysql2::Client#warning_count has been introduced which returns the warning count from the most recent query.
• Mysql2::Client#query_info_string has been introduced which returns an informational string returned by the server about the most recent query.
• The read_timeout connection option has been introduced allowing you to set the read timeout of the connection in seconds.
• The write_timeout connection option has been introduced allowing you to set the write timeout of the connection in seconds.
• The local_infile connection option has been introduced which allows you to enable LOCAL INFILE support.
• BIT field values can be used as boolean fields when cast_bool is enabled.
• We now respect fractional seconds in TIMESTAMP and DATETIME fields (this was introduced in Mysql 5.6.4).

Bug Fixes

• Fix a really long-standing double-free bug related to a Mysql2::Client being freed before a Mysql2::Result that was generated from it. We now do our own refcounting in C as well as a Ruby reference to a Mysql2::Client from it's Mysql2::Result's.
• Fix a compile bug when using the mysql-connector-c related to version compatibility checks in mysql2
• A more explicit error is raised when a single connection is attempted to be shared across threads
• We're more protected against GC-related bugs when compiler optimizations may keep a Ruby object pointer from being visible during GC runs.
• Fix an integer overflow bug with the CLIENT_ constant values
• Compiling the gem should be a little more robust. Some changes were made to extconf to try and make sure we can find libmysql when linking.
• Make sure we read values from the various TIME/DATE field types as unsigned integers.
• Mysql2::Client::EM shouldn't swallow exceptions raised in the deferrable callbacks.
• Passing options to Mysql2::Client#query should no longer persist on the Mysql2::Client object itself but instead only apply to the Mysql2::Result object created by the query as intended.
• Reading Mysql2::Client#affected_rows or Mysql2::Client#last_id after a result has been freed should no longer return garbage.

Optimizations

• Push mysql<->ruby encoding mapping table down into C for a nice speedup
• Use a faster Hash#dup on 1.8.7 when cascading the options hash through Mysql2's objects
• We use rb_intern3 if it's available to create symbol keys when symbolize_keys is enabled to skip creating an intermediary Ruby String.

0.2.19

This release contains all of the same code and therefore release notes as 0.3.12.

The following changes are specific to 0.2.19:

Changes

• The EventMachine ActiveRecord adapter and EM Fiber driver have been removed. You should use https://github.com/igrigorik/em-synchrony instead as it's being maintained there.

Bug fixes

• The ActiveRecord adapter now symbolizes the keys from the connection options hash as early as possible to ensure hash lookups on that hash will work before the Mysql2::Client object is created.
• Make sure a default LIMIT is set when an OFFSET is set.
• A couple of small fixes related to newer ActiveRecord versions since the last mysql2 release
