Pymssql-linux

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

Features
--------

- Custom message handlers (GH-139)

The DB-Library API includes a callback mechanism so applications can provide
functions known as *message handlers* that get passed informative messages
sent by the server which then can be logged, shown to the user, etc.

``_mssql`` now allows you to install your own *message handlers* written in
Python. See the ``_msssql`` examples and reference sections of the
documentation for more details.

Thanks Marc Abramowitz.

- Compatibility with Azure

It is now possible to transparently connect to `SQL Server instances`_
accessible as part of the Azure_ cloud services.

.. note:: If you need to connect to Azure make sure you use FreeTDS 0.91 or
newer.

- Customizable per-connection initialization SQL clauses (both in ``pymssql``
and ``_mssql``) (GH-97)

It is now possible to customize the SQL statements sent right after the
connection is established (e.g. ``'SET ANSI_NULLS ON;'``). Previously
it was a hard-coded list of queries. See the ``_mssql.MSSQLConnection``
documentation for more details.

Thanks Marc Abramowitz.

- Added ability to handle instances of ``uuid.UUID`` passed as parameters for
SQL queries both in ``pymssql`` and ``_mssql``. (GH-209)

Thanks Marat Mavlyutov.

- Allow using `SQL Server autocommit mode`_ from ``pymssql`` at connection
opening time. This allows e.g. DDL statements like ``DROP DATABASE`` to be
executed. (GH-210)

Thanks Marat Mavlyutov.

- Documentation: Explicitly mention minimum versions supported of Python (2.6)
and SQL Server (2005).

- Incremental enhancements to the documentation.

.. _SQL Server instances: http://www.windowsazure.com/en-us/services/sql-database/
.. _Azure: https://www.windowsazure.com/
.. _SQL Server autocommit mode: http://msdn.microsoft.com/en-us/library/ms187878%28v=sql.105%29.aspx

Bug fixes
---------

- Handle errors when calling Stored Procedures via the ``.callproc()`` pymssql
cursor method. Now it will raise a DB-API ``DatabaseException``; previously
it allowed a ``_mssql.MSSQLDatabaseException`` exception to surface.

- Fixes in ``tds_version`` ``_mssql`` connections property value

Made it work with TDS protocol version 7.2. (GH-211)

The value returned for TDS version 7.1 is still 8.0 for backward
compatibility (this is because such feature got added in times when
Microsoft documentation labeled the two protocol versions that followed 7.0
as 8.0 and 9.0; later it changed them to 7.1 and 7.2 respectively) and will
be corrected in a future release (2.2).

- PEP 249 compliance (GH-251)

Added type constructors to increase compatibility with other libraries.

Thanks Aymeric Augustin.

- pymssql: Made handling of integer SP params more robust (GH-237)

- Check lower bound value when convering integer values from to Python to SQL
(GH-238)

Internals
---------

- Completed migration of the test suite from nose to py.test.

- Added a few more test cases to our suite.

- Tests: Modified a couple of test cases so the full suite can be run against
SQL Server 2005.

- Added testing of successful build of documentation to Travis CI script.

- Build process: Cleanup intermediate and ad-hoc anciliary files (GH-231,
GH-273)

- setup.py: Fixed handling of release tarballs contents so no extraneous files
are shipped and the documentation tree is actually included. Also, removed
unused code.

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

Features
--------

- Sphinx-based documentation (GH-149)

Read it online at http://pymssql.org/

Thanks, Ramiro Morales!

See:

* https://github.com/pymssql/pymssql/pull/149
* https://github.com/pymssql/pymssql/pull/162
* https://github.com/pymssql/pymssql/pull/164

* https://github.com/pymssql/pymssql/pull/174
* https://github.com/pymssql/pymssql/pull/175

- "Green" support (GH-135)

Lets you use pymssql with cooperative multi-tasking systems like
gevent and have pymssql call a callback when it is waiting for a
response from the server. You can set this callback to yield to
another greenlet, coroutine, etc. For example, for gevent, you could
do::

def wait_callback(read_fileno):
gevent.socket.wait_read(read_fileno)

pymssql.set_wait_callback(wait_callback)

The above is useful if you're say, running a gunicorn server with the
gevent worker. With this callback in place, when you send a query to
SQL server and are waiting for a response, you can yield to other
greenlets and process other requests. This is super useful when you
have high concurrency and/or slow database queries and lets you use
less gunicorn worker processes and still handle high concurrency.

See https://github.com/pymssql/pymssql/pull/135

- Better error messages.

E.g.: For a connection failure, instead of:

pymssql.OperationalError: (20009, 'Net-Lib error during Connection
refused')

the dberrstr is also included, resulting in:

pymssql.OperationalError: (20009, 'DB-Lib error message 20009,
severity 9:\nUnable to connect: Adaptive Server is unavailable or
does not exist\nNet-Lib error during Connection refused\n')

See:
* https://github.com/pymssql/pymssql/pull/151

In the area of error messages, we also made this change:

execute: Raise ColumnsWithoutNamesError when as_dict=True and missing
column names (GH-160)

because the previous behavior was very confusing; instead of raising
an exception, we would just return row dicts with those columns
missing. This prompted at least one question on the mailing list
(https://groups.google.com/forum/?fromgroups!topic/pymssql/JoZpmNZFtxM),
so we thought it was better to handle this explicitly by raising an
exception, so the user would understand what went wrong.

See:
* https://github.com/pymssql/pymssql/pull/160
* https://github.com/pymssql/pymssql/pull/168

- Performance improvements

You are most likely to notice a difference from these when you are
fetching a large number of rows.

* Reworked row fetching (GH-159)

There was a rather large amount of type conversion occuring when
fetching a row from pymssql. The number of conversions required have
been cut down significantly with these changes.
Thanks Damien, Churchill!

See:
* https://github.com/pymssql/pymssql/pull/158
* https://github.com/pymssql/pymssql/pull/159

* Modify get_row() to use the CPython tuple API (GH-178)

This drops the previous method of building up a row tuple and switches
to using the CPython API, which allows you to create a correctly sized
tuple at the beginning and simply fill it in. This appears to offer
around a 10% boost when fetching rows from a table where the data is
already in memory.
Thanks Damien, Churchill!

See:
* https://github.com/pymssql/pymssql/pull/178

- MSSQLConnection: Add `with` (context manager) support (GH-171)

This adds `with` statement support for MSSQLConnection in the `_mssql`
module -- e.g.::

with mssqlconn() as conn:
conn.execute_query("SELECT version AS version")

We already have `with` statement support for the `pymssql` module.
See:

* https://github.com/pymssql/pymssql/pull/171

- Allow passing in binary data (GH-179)

Use the bytesarray type added in Python 2.6 to signify that this is
binary data and to quote it accordingly. Also modify the handling of
str/bytes types checking the first 2 characters for b'0x' and insert
that as binary data.
See:

* https://github.com/pymssql/pymssql/pull/179

- Add support for binding uuid.UUID instances to stored procedures input
params (GH-143)
Thanks, Ramiro Morales!

See:
* https://github.com/pymssql/pymssql/pull/143
* https://github.com/pymssql/pymssql/commit/1689c83878304f735eb38b1c63c31e210b028ea7

- The version number is now stored in one place, in pymssql_version.h
This makes it easier to update the version number and not forget any
places, like I did with pymssql 2.0.1

* See https://github.com/pymssql/pymssql/commit/fd317df65fa62691c2af377e4661defb721b2699

- Improved support for using py.test as test runner (GH-183)

* See: https://github.com/pymssql/pymssql/pull/183

- Improved PEP-8 and pylint compliance

Bug Fixes

in errmsg()
+ implemented min_error_severity: all errors at or above that
level will raise the exception; if the severity is lower, they
will just accumulate in errmsg()
+ added setting coltype to NUMBER for float types (found by
Jakub Labath)
* setup.py:
+ reincarnated ntwdblib.dll which turned out to be redistributable
after all; pymssql includes the latest version that allows
connecting to SQL 2005; eliminated some stupid notes from the
web page and will ease set up process for users
* apitest_mssql.py: new file
+ provided by Jakub Labath, this file performs some basic DB-API
compliance tests; it immediately triggered the unicode bug
* version 0.7.4

Sat Oct 22 19:41:00 2005 Andrzej Kukula <akukulausers.sourceforge.net>

* version 0.7.2

Sun Sep 4 23:12:00 2005 Andrzej Kukula <akukulausers.sourceforge.net>

* mssqldbmodule.c: improvements and cleanups:
+ improved error handling: if the db function fails, the exception
is thrown automatically and immediately; no need to check
return value of conn.query(), just catch _mssql.error
+ improved error handling: it is possible that MS SQL calls message
handler twice; now _mssql catches and reports both of them at once
+ improved error handling: in some cases _mssql.query() returns
success but the results are invalid; now it is handled properly
(example "SELECT CAST(1234.5678 AS NUMERIC(4,2))")
+ added proper connection initialization: a number of SET statements
are executed upon connection setup to set sensible SQL behaviour;
see source for details; one needs to unset them if needed
+ implemented min_{message|error}_severity as it is in php_mssql
to ignore unimportant errors; it's work in progress
+ new function rmv_lcl() initially by Mark Pettit, to strip locale
crap from MONEY values converted to SQLCHAR while generating
Decimal object
+ other small fixes, improvements and janitorial work

* mssqldbmodule.c: new features:
+ large numbers (DECIMAL, NUMERIC, MONEY, SMALLMONEY) are returned
as Decimal object -- this helps maintain accuracy; thanks to
Mark Pettit for help
+ COMPUTE clauses are supported (it wouldn't fetch data for those
columns before)
+ ROWID type has been removed from _mssql module
+ new type DECIMAL to denote Decimal objects in result set

* mssqldbmodule.c: some improvements:
+ BIT values are returned as Python bool objects, suggested by
Mark Pettit
+ close() method returns None on success (not to be used at all)
and throws exception on error
+ fixed use of uninitialized value when parsing SMALLDATETIME
+ another round of performance improvements in GetRow() - eliminated
unnecessary data conversions and unneeded DB-Lib calls
+ janitorial fixes

Mon Aug 22 04:35:00 2005 Andrzej Kukula <akukulausers.sourceforge.net>

* mssqldbmodule.c: massive diff:
+ fixed bug with fetching query results of some data types;
found by Mark Pettit
+ fixed IndexError when query returns no rows; patch by Jakub Labath
+ rewritten function GetRow() that fetches query results: performance
improvements, better handling of result data types; datetime
is returned as datetime object instead of string (it's more
consistent with other values -- and more pythonic :)
+ eliminated DetermineRowSize()
+ cleanups: _mssql_init() further improvements w.r.t. Python API
+ janitorial fixes
+ added licensing information
* pymssql.py: docstring changed to look nicer with help()
* version 0.7.2

Thu Aug 11 02:12:00 2005 Andrzej Kukula <akukulausers.sourceforge.net>

* mssqldbmodule.c: improved module init function: added doc string,
made compliant with Python 2.0+ module interface (there are no more
coredumps on help())
* mssqldbmodule.c: documented that _mssql.connect() is not portable
between FreeTDS-dependent platforms and Windows platforms; documented
host:port usage

Sat Jul 23 14:20:00 2005 Andrzej Kukula <akukulausers.sourceforge.net>

* mssqldbmodule.c: eliminated problems with Python exiting upon
invalid login credentials with FreeTDS - the culprit was INT_EXIT
and FreeTDS setting DBDEAD
* mssqldbmodule.c: added better error messages (esp. on Windows)
* mssqldbmodule.c: added msg_handler and err_handler debugging
