Mysqlclient

2.0.1

======================
  
  Release: 2020-07-03
  
  * Fixed multithread safety issue in fetching row.

  ======================

2.0.0

======================
  
  Release: 2020-07-02
  
  * Dropped Python 2 support
  * Dropped Django 1.11 support
  * Add context manager interface to Connection which closes the connection on ``__exit__``.
  * Add ``ssl_mode`` option.
  
  
  ======================

1.4.6

======================
  
  Release: 2019-11-21

1.4.2

======================
  
  Release: 2019-02-08
  
  * Fix Django 1.11 compatibility. (327)
  mysqlclient 1.5 will not support Django 1.11.  It is not because

  Release: 2018-12-04
  
  * Support static linking of MariaDB Connector/C (265)
  
  * Better converter for Decimal and Float (267, 268, 273, 286)
  
  * Add ``Connection._get_native_connection`` for XTA project (269)
  
  * Fix SEGV on MariaDB Connector/C when some methods of ``Connection``

  See https://jira.mariadb.org/browse/CONC-289
  
  * Fix ``Connection.client_flag`` (266)
  
  * Fix SSCursor may raise same exception twice (282)
  
  * This removed ``Cursor._last_executed`` which was duplicate of ``Cursor._executed``.
  Both members are private.  So this type of changes are not documented in changelog
  generally.  But Django used the private member for ``last_executed_query`` implementation.
  If you use the method the method directly or indirectly, this version will break
  your application.  See https://code.djangoproject.com/ticket/30013
  
  * ``waiter`` option is now deprecated. (285)
  
  * Fixed SSL support is not detected when built with MySQL < 5.1 (291)

  =====================

1.2.4

=====================
  
  final
  =====
  
  No changes.
  
  
  rc 1
  ====
  
  Fixed a dangling reference to the old types module.
  
  
  beta 5
  ======
  
  Another internal fix for handling remapped character sets.
  
  `_mysql.c` was broken for the case where read_timeout was *not* available. (Issue 6)
  
  Documentation was converted to sphinx but there is a lot of cleanup left to do.
  
  
  beta 4
  ======
  
  Added support for the MySQL read_timeout option. Contributed by
  Jean Schurger (jeanschurger.org).
  
  Added a workaround so that the MySQL character set utf8mb4 works with Python; utf8 is substituted
  on the Python side.
  
  
  beta 3
  ======
  
  Unified test database configuration, and set up CI testing with Travis.
  
  Applied several patches from André Malo (ndparkerusers.sf.net) which fix some issues
  with exception handling and reference counting and TEXT/BLOB conversion.
  
  
  beta 2
  ======
  
  Reverted an accidental change in the exception format. (issue 1)
  
  Reverted some raise statements so that they will continue to work with Python < 2.6
  
  
  beta 1
  ======
  
  A lot of work has been done towards Python 3 compatibility, and avoiding warnings with Python 2.7.
  This includes import changes, converting dict.has_kay(k) to k in dict, updating some test suite methods, etc.
  
  Due to the difficulties of supporting Python 3 and Python < 2.7, 1.2.4 will support Python 2.4 though 2.7.
  1.3.0 will support Python 3 and Python 2.7 and 2.6.
  
  MySQLdb-2.0 is instead going to become moist-1.0. See https://github.com/farcepest/moist
  
  The Windows build has been simplified, and I plan to correct pre-built i386 packages built
  against the python.org Python-2.7 package and MySQL Connector/C-6.0. Contact me if you
  need ia64 packages.
  
  The connection's cursorclass (if not default) was being lost on reconnect.
  
  Newer versions of MySQL don't use OpenSSL and therefore don't have HAVE_SSL defined, but they do have
  a different SSL library. Fixed this so SSL support would be enabled in this case.
  
  The regex that looked for SQL INSERT statement and VALUES in cursor.executemany() was made case-insensitive
  again.
  
  
  =====================

1.2.3

=====================
  
  ez_setup.py has been update to include various fixes that affect the build.
  
  Better Python version and dependency detection as well as eliminate exception
  warnings under Python 2.6.
  
  Eliminated memory leaks related to Unicode and failed connections.
  
  Corrected connection .escape() functionality.
  
  Miscellaneous cleanups and and expanded testing suite to ensure ongoing release
  quality.
  
  =====================

1.2.2

=====================
  
  The build system has been completely redone and should now build
  on Windows without any patching; uses setuptools.
  
  Added compatibility for Python 2.5, including support for with statement.
  
  connection.ping() now takes an optional boolean argument which can
  enable (or disable) automatic reconnection.
  
  Support returning SET columns as Python sets was removed due to an
  API bug in MySQL; corresponding test removed.
  
  Added a test for single-character CHAR columns.
  
  BLOB columns are now returned as Python strings instead of byte arrays.
  
  BINARY character columns are always returned as Python strings, and not
  unicode.
  
  Fixed a bug introduced in 1.2.1 where the new SHOW WARNINGS support broke
  SSCursor.
  
  Only encode the query (convert to a string) when it is a unicode instance;
  re-encoding encoded strings would break things.
  
  Make a deep copy of conv when connecting, since it can be modified.
  
  Added support for new VARCHAR and BIT column types.
  
  DBAPISet objects were broken, but nobody noticed.
  
  
  ========================

1.2.1

=====================
  
  Switched to Subversion. Was going to do this for 1.3, but a
  SourceForge CVS outage has forced the issue.
  
  Mapped a lot of new 4.1 and 5.0 error codes to Python exceptions
  
  Added an API call for mysql_set_character_set(charset) (MySQL > 5.0.7)
  
  Added an API call for mysql_get_character_set_info() (MySQL > 5.0.10)
  
  Revamped the build system. Edit site.cfg if necessary (probably not
  in most cases)
  
  Python-2.3 is now the minimum version.
  
  Dropped support for mx.Datetime and stringtimes; always uses Python
  datetime module now.
  
  Improved unit tests
  
  New connect() options:
  * charset: sets character set, implies use_unicode
  * sql_mode: sets SQL mode (i.e. ANSI, etc.; see MySQL docs)
  
  When using MySQL-4.1 or newer, enables MULTI_STATEMENTS
  
  When using MySQL-5.0 or newer, enables MULTI_RESULTS
  
  When using MySQL-4.1 or newer, more detailed warning messages
  are produced
  
  SET columns returned as Python Set types; you can pass a Set as
  a parameter to cursor.execute().
  
  Support for the new MySQL-5.0 DECIMAL implementation
  
  Support for Python Decimal type
  
  Some use of weak references internally. Cursors no longer leak
  if you don't close them. Connections still do, unfortunately.
  
  ursor.fetchXXXDict() methods raise DeprecationWarning
  
  cursor.begin() is making a brief reappearence.
  
  cursor.callproc() now works, with some limitations.

1.2.1_p2

========================
  
  There are some minor build fixes which probably only affect MySQL
  older than 4.0.
  
  If you had MySQL older than 4.1, the new charset and sql_mode
  parameters didn't work right. In fact, it was impossible to create
  a connection due to the charset problem.
  
  If you are using MySQL-4.1 or newer, there is no practical difference
  between 1.2.1 and 1.2.1_p2, and you don't need to upgrade.
