This mechanism is easily subverted by a forger. The goal is to detect accidental edits. <li> Improved de-quoting of column names for [CREATE TABLE AS] statements with an aggregate query on the right-hand side. <li> Fewer "stat()" system calls issued by the unix VFS. <li> Enhanced the [LIKE optimization] so that it works with an ESCAPE clause. <li> Enhance [PRAGMA integrity_check] and [PRAGMA quick_check] to detect obscure row corruption that they were formerly missing. Also update both pragmas so that they return error text rather than SQLITE_CORRUPT when encountering low-level corruption. <li> Pass information about !=, IS, IS NOT, NOT NULL, and IS NULL constraints into the [xBestIndex] method of virtual tables. <li> Enhanced the [CSV virtual table] so that it accepts the last row of input if the final new-line character is missing. <li> Remove the rarely-used "scratch" memory allocator. Replace it with the [SQLITE_CONFIG_SMALL_MALLOC] configuration setting that gives SQLite a hint large memory allocations should be avoided when possible. |
