CI

  • Run tests with Python 3.8 at AppVeyor.

SQLObject 3.8.0

Released 7 Dec 2019.

Features

  • Add driver supersqlite. Not all tests are passing so the driver isn’t added to the list of default drivers.

Minor features

  • Improve sqlrepr’ing ALL/ANY/SOME(): always put the expression at the right side of the comparison operation.

Bug fixes

  • Fixed a bug in cascade deletion/nullification.

SQLObject 3.7.2

Released 1 May 2019.

Minor features

  • Adapt Postgres exception handling to psycopg2 version 2.8: in the recent psycopg2 errors are in psycopg2.errors module.

SQLObject 3.7.1

Released 2 Feb 2019.

SQLObject 3.7.0

Released 6 June 2018.

Features

  • Add signals on commit and rollback; pull request by Scott Stahl.

Tests

SQLObject 3.6.0

Released 24 Feb 2018.

Minor features

  • Close cursors after using to free resources immediately instead of waiting for gc.

Bug fixes

  • Fix for TypeError using selectBy on a BLOBCol. PR by Michael S. Root.

Drivers

  • Extend support for oursql and Python 3 (requires our fork of the driver).
  • Fix cursor.arraysize - pymssql doesn’t have arraysize.
  • Set timeout for ODBC with MSSQL.
  • Fix _setAutoCommit for MSSQL.

Documentation

  • Document extras that are available for installation.

Build

  • Use python_version environment marker in setup.py to make install_requires and extras_require declarative. This makes the universal wheel truly universal.
  • Use python_requires keyword in setup.py.

SQLObject 3.5.0

Released 15 Nov 2017.

Minor features

  • Add Python3 special methods for division to SQLExpression. Pull request by Michael S. Root.

Drivers

  • Add support for pg8000 PostgreSQL driver.
  • Fix autoreconnect with pymysql driver. Contributed by Shailesh Mungikar.

Documentation

  • Remove generated HTML from eggs/wheels (docs are installed into wrong place). Generated docs are still included in the source distribution.

Tests

  • Add tests for PyGreSQL, py-postgresql and pg8000 at AppVeyor.
  • Fixed bugs in py-postgresql at AppVeyor. SQLObject requires the latest version of the driver from our fork.

SQLObject 3.4.0

Released 5 Aug 2017.

Features

  • Python 2.6 is no longer supported. The minimal supported version is Python 2.7.

Drivers (work in progress)

  • Encode binary values for py-postgresql driver. This fixes the last remaining problems with the driver.

  • Encode binary values for PyGreSQL driver using the same encoding as for py-postgresql driver. This fixes the last remaining problems with the driver.

    Our own encoding is needed because unescape_bytea(escape_bytea()) is not idempotent. See the comment for PQunescapeBytea at https://www.postgresql.org/docs/9.6/static/libpq-exec.html:

    This conversion is not exactly the inverse of PQescapeBytea, because the string is not expected to be “escaped” when received from PQgetvalue. In particular this means there is no need for string quoting considerations.

  • List all drivers in extras_require in setup.py.

Minor features

  • Use base64.b64encode/b64decode instead of deprecated encodestring/decodestring.

Tests

  • Fix a bug with sqlite-memory: rollback transaction and close connection. The solution was found by Dr. Neil Muller.
  • Use remove-old-files.py from ppu to cleanup pip cache at Travis and AppVeyor.
  • Add test_csvimport.py more as an example how to use load_csv from sqlobject.util.csvimport.

SQLObject 3.3.0

Released 7 May 2017.

Features

  • Support for Python 2.6 is declared obsolete and will be removed in the next release.

Minor features

  • Convert scripts repository to devscripts subdirectory. Some of thses scripts are version-dependent so it’s better to have them in the main repo.
  • Test for __nonzero__ under Python 2, __bool__ under Python 3 in BoolCol.

Drivers (work in progress)

  • Add support for PyODBC and PyPyODBC (pure-python ODBC DB API driver) for MySQL, PostgreSQL and MS SQL. Driver names are pyodbc, pypyodbc or odbc (try pyodbc and pypyodbc). There are some problems with pyodbc and many problems with pypyodbc.

Documentation

Tests

  • Run tests at Travis CI and AppVeyor with Python 3.6, x86 and x64.
  • Stop running tests at Travis with Python 2.6.
  • Stop running tests at AppVeyor with pymssql - too many timeouts and problems.

SQLObject 3.2.0

Released 11 Mar 2017.

Minor features

  • Drop table name from VACUUM command in SQLiteConnection: SQLite doesn’t vacuum a single table and SQLite 3.15 uses the supplied name as the name of the attached database to vacuum.
  • Remove driver keyword from RdbhostConnection as it allows one driver rdbhdb.
  • Add driver keyword for FirebirdConnection. Allowed values are ‘fdb’, ‘kinterbasdb’ and ‘pyfirebirdsql’. Default is to test ‘fdb’ and ‘kinterbasdb’ in that order. pyfirebirdsql is supported but has problems.
  • Add driver keyword for MySQLConnection. Allowed values are ‘mysqldb’, ‘connector’, ‘connector-python’, ‘oursql’ and ‘pymysql’. Default is to test for mysqldb only.
  • Add support for MySQL Connector (pure python; binary packages are not at PyPI and hence are hard to install and test).
  • Add support for oursql MySQL driver (only Python 2.6 and 2.7 until oursql author fixes Python 3 compatibility).
  • Add support for PyMySQL - pure python mysql interface).
  • Add parameter timeout for MSSQLConnection (usable only with pymssql driver); timeouts are in seconds.
  • Remove deprecated ez_setup.py.

Drivers (work in progress)

  • Extend support for PyGreSQL driver. There are still some problems.
  • Add support for py-postgresql PostgreSQL driver. There are still problems with the driver.
  • Add support for pyfirebirdsql.There are still problems with the driver.

Bug fixes

  • Fix MSSQLConnection.columnsFromSchema: remove ( and ) from default value.
  • Fix MSSQLConnection and SybaseConnection: insert default values into a table with just one IDENTITY column.
  • Remove excessive NULLs from CREATE TABLE for MSSQL/Sybase.
  • Fix concatenation operator for MSSQL/Sybase (it’s +, not ||).
  • Fix MSSQLConnection.server_version() under Py3 (decode version to str).

Documentation

  • The docs are now generated with Sphinx.
  • Move docs/LICENSE to the top-level directory so that Github recognizes it.

Tests

  • Rename py.test -> pytest in tests and docs.
  • Great Renaming: fix pytest warnings by renaming TestXXX classes to SOTestXXX to prevent pytest to recognize them as test classes.
  • Fix pytest warnings by converting yield tests to plain calls: yield tests were deprecated in pytest.
  • Tests are now run at CIs with Python 3.5.
  • Drop Circle CI.
  • Run at Travis CI tests with Firebird backend (server version 2.5; drivers fdb and firebirdsql). There are problems with tests.
  • Run tests at AppVeyor for windows testing. Run tests with MS SQL, MySQL, Postgres and SQLite backends; use Python 2.7, 3.4 and 3.5, x86 and x64. There are problems with MS SQL and MySQL.
