SQLite

3.6.15

Released on 15 Jun 2009
Project description.

SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. The code for SQLite is in the public domain and is thus free for use for any purpose, commercial or private. SQLite is the most widely deployed database in the world with more applications than we can count, including several high-profile projects.

SQLite is an embedded SQL database engine. Unlike most other SQL databases, SQLite does not have a separate server process. SQLite reads and writes directly to ordinary disk files. A complete SQL database with multiple tables, indices, triggers, and views, is contained in a single disk file. The database file format is cross-platform - you can freely copy a database between 32-bit and 64-bit systems or between big-endian and little-endian architectures. These features make SQLite a popular choice as an Application File Format.

SQLite 3.6.15 Changelog
  • Refactor the internal representation of SQL expressions so that they use less memory on embedded platforms.
  • Reduce the amount of stack space used
  • Fix an 64-bit alignment bug on HP/UX and Sparc
  • The sqlite3_create_function() family of interfaces now return SQLITE_MISUSE instead of SQLITE_ERROR when passed invalid parameter combinations.
  • When new tables are created using CREATE TABLE ... AS SELECT ... the datatype of the columns is the simplified SQLite datatype (TEXT, INT, REAL, NUMERIC, or BLOB) instead of a copy of the original datatype from the source table.
  • Resolve race conditions when checking for a hot rollback journal.
  • The sqlite3_shutdown() interface frees all mutexes under windows.
  • Enhanced robustness against corrupt database files
  • Continuing improvements to the test suite and fixes to obscure bugs and inconsistencies that the test suite improvements are uncovering.
