Log Message:
databases/py-sqlite2: Update to 2.8.3.

Version 2.8.3
-------------

- Fixed bug where cursor.description was an emtpy tuple instead of None for
  non-SELECT statements

Version 2.8.2
-------------

- Make sure pysqlite compiles with Visual Studio, which does not support C99
- Switch to sqlite3_open_v2. The flags parameter is now exposed. You can use it
  to modify the behaviour of the opened database connection, for example
  opening a database file in read-only mode or enable URI mode.

Version 2.8.1
-------------

BUG FIXES

- Fixed multiple refcount problems.

IMPROVEMENTS

- Added versionchanged about changed transaction behaviour wrt DDL statements
  to documentation.
- I was informed by Roger Binns that FTS5 is not stable yet. The amalgamation
  is now built with FTS3 and FTS4 instead.

Version 2.8.0
-------------

NEW FEATURES

- No new features, but tons of bugfixes. These mean that things now work that
  didn't before:
- Transactional DDL now works
- You can use SAVEPOINTs now

BUILD PROCESS

- Python 2.7.x is now required. If trying to use it with Python 3, print a
  useful error message.  Integrated all fixes from the sqlite3 module in Python
  2.7.10.

MAJOR IMPROVEMENTS

- Completety got rid of statement parsing. We now use SQLite functions to
  determine if a statement modifies the database or not. If a statement
  modifies the database, then we implicitly start a transaction. For backwards
  compatibility reasons, we do NOT implicitly start a transaction if we
  encounter a DDL statement.

  You can, however, now have transactional DDL if you want to:

    cur = con.cursor()
    cur.execute("begin")
    cur.execute("create table foo(bar)")
    con.rollback()

  This also means that people can now finally use SAVEPOINTS.

- Use sqlite3_get_autocommit() to determine if we are within a transaction
  instead of trying to be smart.

- Switch to v2 statement API. This simplified the code and will increase
  stability.

MINOR IMPROVEMENTS

- You can use unicode strings as index for Row objects.

BUGFIXES

- Fixed a regression: statements should not be reset after a commit.

GENERAL CLEANUP AND DEPRECATIONS

- Since december 2005, row_factory is a feature of the Connection class
  instead of the Cursor class.
- DEPRECATE converters and adapters.
- DEPRECATE text_factory.
- Remove compatibility workarounds for old Python versions.
- Remove workarounds for old SQLite versions.
- Remove apsw related code.

Version 2.7.0
-------------

NEW FEATURES

- The limit functionality of SQLite is now wrapped.

BUILD PROCESS

- Instead of fts3, build fts5 extension when using amalgamation.
- use pkg-config for finding SQLite if available
- Removed the download/unpacking of SQLite amalgamation files.

IMPROVEMENTS

- Use toc.db file from the SQLite web site and a custom script to make sure
  that we have all integer constants mapped to Python.
- Use Travis CI
- Added Trove classifier to make sure Python 3 users do not accidentally
  try to install it.

BUGFIXES

- Fix for parsing fractional second part of timestamps.
- Fixed bug where when using converters, empty strings ended up as None
  on the Python side.
- SQLite can cope with text with embedded NUL. We can now, too.
- many others
