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
Problems found with existing distfiles:
distfiles/D6.data.ros.gz
distfiles/cstore0.2.tar.gz
distfiles/data4.tar.gz
distfiles/sphinx-2.2.7-release.tar.gz
No changes made to the cstore or mariadb55-client distinfo files.
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.
Remove devel/py-ctypes (only needed by and supporting python24).
Remove PYTHON_VERSIONS_ACCEPTED and PYTHON_VERSIONS_INCOMPATIBLE
lines that just mirror defaults now.
Miscellaneous cleanup while editing all these files.
changes: many bugfixes and compatibility fixes
The 2.5.0 version in pkgsrc was broken:
>>> from pysqlite2 import dbapi2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/pkg/lib/python2.5/site-packages/pysqlite2/dbapi2.py", line 27, in <module>
from pysqlite2._sqlite import *
ImportError: /usr/pkg/lib/python2.5/site-packages/pysqlite2/_sqlite.so: Undefined PLT symbol "sqlite3_enable_load_extension" (symnum = 158)
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
2.5.0:
- Windows binaries are now cross-built using mingw on Linux
- import various fixes from Python 2.6 version
- Connection has new method iterdump() that allows you to create a script file
that can be used to clone a database
- the docs are now built using Sphinx and were imported from Python 2.6's
sqlite3 module
- Connection.enable_load_extension(enabled) to allow/disallow extension
loading. Allows you to use fulltext search extension, for example ;-)
- Give the remaining C functions used in multiple .c source files the pysqlite_
prefix.
- Release GIL during sqlite3_prepare() calls for better concurrency.
- Automatically download the SQLite amalgamation when building statically.
2.4.1:
- Made unicode strings for the database parameter in connect() work again
- Removed bad defaults from setup.cfg
2.4.0:
- Implemented context managers. pysqlite's connections can now be used as
context managers with Python 2.5 or later:
from __future__ import with_statement
from pysqlite2 import dbapi2 as sqlite
con = sqlite.connect(":memory:")
con.execute("create table person (id integer primary key, firstname varchar unique)")
# Successful, con.commit() is called automatically afterwards
with con:
con.execute("insert into person(firstname) values (?)", ("Joe",))
# con.rollback() is called after the with block finishes with an exception, the
# exception is still raised and must be catched
try:
with con:
con.execute("insert into person(firstname) values (?)", ("Joe",))
except sqlite.IntegrityError:
print "couldn't add Joe twice"
- pysqlite connections can now be created from APSW connections. This enables
users to use APSW functionality in applications using the DB-API from
pysqlite:
from pysqlite2 import dbapi2 as sqlite
import apsw
apsw_con = apsw.Connection(":memory:")
apsw_con.createscalarfunction("times_two", lambda x: 2*x, 1)
# Create pysqlite connection from APSW connection
con = sqlite.connect(apsw_con)
result = con.execute("select times_two(15)").fetchone()[0]
assert result == 30
con.close()
Caveat: This will only work if both pysqlite and APSW are dynamically
linked against the same SQLite shared library. Otherwise you will
experience a segfault.
- Fixed shuffled docstrings for fetchXXX methods.
- Workaround for SQLite 3.5.x versions which apparently return NULL for
"no-operation" statements.
- Disable the test for rollback detection on old SQLite versions. This prevents
test failures on systems that ship outdated SQLite libraries like MacOS X.
- Implemented set_progress_handler for progress callbacks from SQLite. This is
particularly useful to update GUIs during long-running queries. Thanks to
exarkun for the original patch.
