Pysqlite

-------------

(released on August 30th 2016)

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

-------------

(released on March 26th 2016)

- 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.

(released on August 23rd 2015)

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.

(released on August 19th 2015)

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. It was kept in the Cursor class for backwards
compatibility. Now it was time to finally remove it from 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.

(released on August 12th 2015)

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. If you now want
to statically build against the SQLite amalgamation files, download them
yourself and put them in the pysqlite root directory.

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
