* Fix an old and very obscure bug that can lead to corruption of the database free-page list when incremental_vacuum is used. Changes 3.7.1: * Added new commands SQLITE_DBSTATUS_SCHEMA_USED and SQLITE_DBSTATUS_STMT_USED to the sqlite3_db_status() interface, in order to report out the amount of memory used to hold the schema and prepared statements of a connection. * Increase the maximum size of a database pages from 32KiB to 64KiB. * Use the LIKE optimization even if the right-hand side string contains no wildcards. * Added the SQLITE_FCNTL_CHUNK_SIZE verb to the sqlite3_file_control() interface for both unix and windows, to cause database files to grow in large chunks in order to reduce disk fragmentation. * Fixed a bug in the query planner that caused performance regresssions relative to 3.6.23.1 on some complex joins. * Fixed a typo in the OS/2 backend. * Refactored the pager module. * The SQLITE_MAX_PAGE_SIZE compile-time option is now silently ignored. The maximum page size is hard-coded at 65536 bytes. |
