| 10 | +- Compatibility with Azure |
| 11 | + |
| 12 | + It is now possible to transparently connect to `SQL Server instances`_ |
| 13 | + accessible as part of the Azure_ cloud services. |
| 14 | + |
| 15 | + .. note:: If you need to connect to Azure make sure you use FreeTDS 0.91 or newer. |
| 16 | + |

| 18 | +.. _Azure: https://www.windowsazure.com/ |

| 26 | +- Sphinx-based documentation (GH-149) |
| 27 | + |
| 28 | + Read it online at http://pymssql.org/ |
| 29 | + |
| 30 | + Thanks, Ramiro Morales! |

| 42 | + |
| 43 | +- "Green" support (GH-135) |
| 44 | + |
| 45 | + Lets you use pymssql with cooperative multi-tasking systems like |
| 46 | + gevent and have pymssql call a callback when it is waiting for a |
| 47 | + response from the server. You can set this callback to yield to |
| 48 | + another greenlet, coroutine, etc. For example, for gevent, you could |
| 49 | + do:: |
| 50 | + |
| 51 | + def wait_callback(read_fileno): |
| 52 | + gevent.socket.wait_read(read_fileno) |
| 53 | + |
| 54 | + pymssql.set_wait_callback(wait_callback) |
| 55 | + |
| 56 | + The above is useful if you're say, running a gunicorn server with the |
| 57 | + gevent worker. With this callback in place, when you send a query to |
| 58 | + SQL server and are waiting for a response, you can yield to other |
| 59 | + greenlets and process other requests. This is super useful when you |
| 60 | + have high concurrency and/or slow database queries and lets you use |
| 61 | + less gunicorn worker processes and still handle high concurrency. |
| 62 | + |
| 63 | + See https://github.com/pymssql/pymssql/pull/135 |
| 64 | + |
| 65 | +- Better error messages. |
| 66 | + |
| 67 | + E.g.: For a connection failure, instead of: |
| 68 | + |
| 69 | + pymssql.OperationalError: (20009, 'Net-Lib error during Connection |
| 70 | + refused') |
| 71 | + |
| 72 | + the dberrstr is also included, resulting in: |
| 73 | + |
| 74 | + pymssql.OperationalError: (20009, 'DB-Lib error message 20009, |
| 75 | + severity 9:\nUnable to connect: Adaptive Server is unavailable or |
| 76 | + does not exist\nNet-Lib error during Connection refused\n') |
| 77 | + |
| 78 | + See: |
| 79 | + * https://github.com/pymssql/pymssql/pull/151 |
| 80 | + |
| 81 | + In the area of error messages, we also made this change: |
| 82 | + |
| 83 | + execute: Raise ColumnsWithoutNamesError when as_dict=True and missing |
| 84 | + column names (GH-160) |
| 85 | + |
| 86 | + because the previous behavior was very confusing; instead of raising |
| 87 | + an exception, we would just return row dicts with those columns |
| 88 | + missing. This prompted at least one question on the mailing list |
| 89 | + (https://groups.google.com/forum/?fromgroups#!topic/pymssql/JoZpmNZFtxM), |
| 90 | + so we thought it was better to handle this explicitly by raising an |
| 91 | + exception, so the user would understand what went wrong. |
| 92 | + |
| 93 | + See: |
| 94 | + * https://github.com/pymssql/pymssql/pull/160 |
| 95 | + * https://github.com/pymssql/pymssql/pull/168 |
| 96 | + |
| 97 | +- Performance improvements |
| 98 | + |
| 99 | + You are most likely to notice a difference from these when you are |
| 100 | + fetching a large number of rows. |
| 101 | + |
| 102 | + * Reworked row fetching (GH-159) |
| 103 | + |
| 104 | + There was a rather large amount of type conversion occuring when |
| 105 | + fetching a row from pymssql. The number of conversions required have |
| 106 | + been cut down significantly with these changes. |
| 107 | + Thanks Damien, Churchill! |
| 108 | + |
| 109 | + See: |
| 110 | + * https://github.com/pymssql/pymssql/pull/158 |
| 111 | + * https://github.com/pymssql/pymssql/pull/159 |
| 112 | + |
| 113 | + * Modify get_row() to use the CPython tuple API (GH-178) |
| 114 | + |
| 115 | + This drops the previous method of building up a row tuple and switches |
| 116 | + to using the CPython API, which allows you to create a correctly sized |
| 117 | + tuple at the beginning and simply fill it in. This appears to offer |
| 118 | + around a 10% boost when fetching rows from a table where the data is |
| 119 | + already in memory. |
| 120 | + Thanks Damien, Churchill! |
| 121 | + |
| 122 | + See: |
| 123 | + * https://github.com/pymssql/pymssql/pull/178 |
| 124 | + |
| 125 | +- MSSQLConnection: Add `with` (context manager) support (GH-171) |
| 126 | + |
| 127 | + This adds `with` statement support for MSSQLConnection in the `_mssql` |
| 128 | + module -- e.g.: |
| 129 | + |
| 130 | + with mssqlconn() as conn: |
| 131 | + conn.execute_query("SELECT @@version AS version") |
| 132 | + |
| 133 | + We already have `with` statement support for the `pymssql` module. |
| 134 | + |
| 135 | + See: |
| 136 | + * https://github.com/pymssql/pymssql/pull/171 |
| 137 | + |
| 138 | +- Allow passing in binary data (GH-179) |
| 139 | + |
| 140 | + Use the bytesarray type added in Python 2.6 to signify that this is |
| 141 | + binary data and to quote it accordingly. Also modify the handling of |
| 142 | + str/bytes types checking the first 2 characters for b'0x' and insert |
| 143 | + that as binary data. |
| 144 | + |
| 145 | + See: |
| 146 | + * https://github.com/pymssql/pymssql/pull/179 |
| 147 | + |
| 148 | +- Add support for binding uuid.UUID instances to stored procedures input |
| 149 | + params (GH-143) |
| 150 | + Thanks, Ramiro Morales! |
| 151 | + See: |
| 152 | + * https://github.com/pymssql/pymssql/pull/143 |
| 153 | + * https://github.com/pymssql/pymssql/commit/1689c83878304f735eb38b1c63c31e210b028ea7 |
| 154 | + |
| 155 | +- The version number is now stored in one place, in pymssql_version.h |
| 156 | + This makes it easier to update the version number and not forget any |
| 157 | + places, like I did with pymssql 2.0.1 |
| 158 | + * See https://github.com/pymssql/pymssql/commit/fd317df65fa62691c2af377e4661defb721b2699 |
| 159 | + |
| 160 | +- Improved support for using py.test as test runner (GH-183) |
| 161 | + * See: https://github.com/pymssql/pymssql/pull/183 |
| 162 | + |
| 163 | +- Improved PEP-8 and pylint compliance |
| 164 | + |
