Change Log
==========
Version 2.x.y - To be released
==============================
Features
--------
- Compatibility with Azure
It is now possible to transparently connect to `SQL Server instances`_
accessible as part of the Azure_ cloud services.
.. _SQL Server instances: http://www.windowsazure.com/en-us/services/sql-database/
.. _Azure: https://www.windowsazure.com/
Documentation
-------------
- Make it explicit the minimum FreeTDS version supported: 0.91
Version 2.1.0 - 2014-02-25 - `Marc Abramowitz <http://marc-abramowitz.com/>`_
=============================================================================
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/165
* https://github.com/pymssql/pymssql/pull/166
* https://github.com/pymssql/pymssql/pull/167
* https://github.com/pymssql/pymssql/pull/169
* 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
---------
- GH-142 ("Change how *.pyx files are included in package") - this
should prevent pymssql.pyx and _mssql.pyx from getting copied into the
root of your virtualenv. Thanks, @Arfrever!
* See: https://github.com/pymssql/pymssql/issues/142
- GH-145 ("Prevent error string growing with repeated failed connection
attempts.")
See:
* https://github.com/pymssql/pymssql/issues/145
* https://github.com/pymssql/pymssql/pull/146
- GH-151 ("err_handler: Don't clobber dberrstr with oserrstr")
* https://github.com/pymssql/pymssql/pull/151
- GH-152 ("_mssql.pyx: Zero init global last_msg_* vars")
See: https://github.com/pymssql/pymssql/pull/152
- GH-177 ("binary columns sometimes are processed as varchar")
Better mechanism for pymssql to detect that user is passing binary
data.
See: https://github.com/pymssql/pymssql/issues/177
- buffer overflow fix (GH-182)
* See: https://github.com/pymssql/pymssql/pull/181
* See: https://github.com/pymssql/pymssql/pull/182
- Return uniqueidentifer columns as uuid.UUID objects on Python 3

sub-seconds correctly") - Pad microseconds to 3 digits so it gets
converted correctly. Thanks, Ken Robbins (kenneth.robbins at gmail)!
(5d0c980ef8b8)
* Make tests/test_queries.py actually run tests. It looked like it was
half-finished and not working. This fills it out and makes it work and
actually test a few things. (5373541eb899)
* setup.py: Make it possible to use `python setup.py test`
(3c32acb41251)
* Bunch of fixes to eliminate build/install warnings (adb0fc75bfd0,

Skip test because it fails with some versions of FreeTDS but passes
with others. (d05341273673)
* Fix issue 116 ("A few tests fail if running on a system that has SQL
Server available on port 1433") (0fc4086447fe)
* Modify tests/test_config.py to use server='dontnameyourserverthis'
when doing various tests so it doesn't try to connect to a SQL
Server listening on localhost:1433 (0fc4086447fe)
* tox.ini: Add {posargs:-w tests -v} to nosetests invocation so that
we can pass arguments to tox -- e.g.: to run only specific tests

* tox.ini: Add "ipdb" to deps, because the IPython debugger is very
nice for debugging why tests are failing (be9ee40156cb)
* Fix issue 114 ("Fix SP name handling in threaded test so we can
actually run it.") (6ac2b75747ad)

connection instantiated with as_dict=True."): Add a test which
illustrates that the issue is resolved. (058d761cc761)
* Fix issue 60 ("cursor.execute raise UnicodeDecodeError if query and
params in unicode"): Add patch from tonal.promsoft and add tests.
(49210c03a6cf)
* Add *.c to MANIFEST.in so they get included in sdist and end-users
don't need to run Cython. (25c1a84aac0c)
* Fix issue 56 ("callproc do not accept None and unicode string in
parameters"): Add patch from tonal.promsoft and add tests
(939eb7939136)
* version 2.0.0b1-dev-20130403

Tue Dec 27 15:14:00 2005 Andrzej Kukula <[email protected]>
* mssqldbmodule.c: bug fixes, improvements and cleanups:
+ implemented set_login_timeout() and set_query_timeout() functions;
+ eliminated unnecessary ODBC code
+ cleaned up exception code and improved exception handling,
SF bug #1335560
+ web page now correctly mentions FreeTDS 0.63 as the minimal
required version
+ stdmsg() method is now deprecated; all errors are concatenated
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 <[email protected]>
* mssqldbmodule.c: multithreading improvements - from now on pymssql
is thread-safe, it releases GIL in proper places; idea and initial
patch by John-Peter Lee (thanks very much!)
Mon Sep 5 23:29:00 2005 Andrzej Kukula <[email protected]>
* setup.py: fixed an installation issue regarding importing pymssql

* version 0.7.2
Sun Sep 4 23:12:00 2005 Andrzej Kukula <[email protected]>
* 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
Tue Aug 30 00:16:00 2005 Andrzej Kukula <[email protected]>
* mssqldbmodule.c: new features:

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
Mon Aug 29 21:59:00 2005 Andrzej Kukula <[email protected]>
* mssqldbmodule.c: some improvements:

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 <[email protected]>
* 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

more builtin Python features; some redundant code removed; memset()
removed as there were no benefits but performance decrease

* pymssql.py: _quote: removed escaping backslash -- with MSSQL it is
only needed to escape single quotes by duplicating them

DB-API 2.0 (see .close() in PEP 249)
* version 0.7.1
