| 12:38 | Omit the sqlite3IntTokens array constant for a code simplification. file: [a1a8d698] check-in: [f907395e] user: drh branch: trunk, size: 13795 | |
|
2019-08-12
| ||
| 14:17 | Add a TESTCTRL that disables the verification of type, name, and tbl_name in the sqlite_master table. file: [d7a7a45a] check-in: [48d9b48a] user: drh branch: trunk, size: 13908 | |
|
2019-08-02
| ||
| 20:45 | Add the SQLITE_TESTCTRL_PRNG_SEED test control. file: [0c9c4584] check-in: [3ac57231] user: drh branch: prng-seed-test-control, size: 13853 | |
|
2019-06-14
| ||
| 17:37 | Deprecate the SQLITE_ALLOW_COVERING_INDEX_SCAN compile-time option when it is turned off. This probably will impact no-one. If it does, they will get an error message instructing them to contact developers, so that we can get feedback that somebody is actually using this feature. Start-time disabling of covering index scan is not affected. file: [1e942b1e] check-in: [23e49f99] user: drh branch: trunk, size: 13807 | |
|
2019-01-31
| ||
| 15:38 | Add the SQLITE_CONFIG_MEMDB_MAXSIZE configuration option for configuring the default maximum size of an in-memory database created using sqlite3_deserialize(). This is necessary to make the interface reasonably testable. file: [0dea3065] check-in: [cb72ee04] user: drh branch: trunk, size: 13500 | |
|
2018-11-26
| ||
| 18:09 | Do not allow direct access to internal-use SQL functions such as sqlite_rename_column() and sqlite3_rename_table() except when the new SQLITE_TESTCTRL_INTERNAL_FUNCTIONS flag is set. file: [8291eee0] check-in: [6e133054] user: drh branch: trunk, size: 13217 | |
|
2018-06-19
| ||
| 19:01 | OFD locks are now mostly working, but need additional tests. file: [58ab3df8] check-in: [4f1fb5c9] user: drh branch: ofd-locks, size: 13208 | |
|
2018-04-16
| ||
| 21:12 | Add SQLITE_CONFIG_SORTERREF_SIZE configuration option. file: [9bf034fd] check-in: [b25a7bb7] user: dan branch: sorter-reference, size: 13162 | |
|
2018-02-12
| ||
| 20:27 | When compiling with VDBE_PROFILE, add the sqlite3NProfileCnt global variable which can be used to measure per-opcode values other than elapse time, if non-zero. file: [01506976] check-in: [d44d5936] user: drh branch: trunk, size: 13109 | |
|
2017-08-28
| ||
| 15:51 | Remove the rarely-used scratch memory allocator. This makes the code smaller, faster, and easier to maintain. In place of the scratch allocator, add the SQLITE_CONFIG_SMALL_MALLOC configuration option that provides a hint to SQLite that large memory allocations should be avoided. file: [ac3094f1] check-in: [54b00024] user: drh branch: trunk, size: 12905 | |
|
2017-05-03
| ||
| 15:54 | Always enable URI filenames when compiling with SQLITE_HAS_CODEC. Also allow plaintext keys using the key= query parameter. file: [8a6ab6b4] check-in: [31a51b4d] user: drh branch: trunk, size: 12992 | |
|
2017-01-02
| ||
| 19:02 | Provide the SQLITE_DEFAULT_LOOKASIDE compile-time option and make it's default value be 1200,100 (raised from 512,125 in the latest release). file: [4a34512d] check-in: [584da48f] user: drh branch: trunk, size: 12847 | |
|
2016-12-21
| ||
| 21:26 | Change the default lookaside configuration from 500 slots of 128 bytes each to 125 slots of 512 bytes each. This uses the same amount of memory (64,000 bytes) but seems to perform much better in test applications. file: [dcdb89f3] check-in: [52a12e47] user: drh branch: trunk, size: 12396 | |
|
2016-12-07
| ||
| 15:49 | Rename the SQLITE_OMIT_BUILTIN_TEST compile-time option to SQLITE_UNTESTABLE. file: [235021a2] check-in: [f3608187] user: drh branch: trunk, size: 12396 | |

|
2016-09-18
| ||
| 16:08 | Revise the implementation of OP_Once so that it is smaller, faster, and uses less memory. This also fixes an obscure bug introduced 3 days ago by check-in [5990a1bdb4a073]. file: [2917bbc4] check-in: [6bf5ba10] user: drh branch: trunk, size: 12541 | |
|
2016-04-11
| ||
| 19:01 | Performance optimization to sqlite3Dequote() and its callers. file: [c45ea22a] check-in: [9efe2265] user: drh branch: trunk, size: 12485 | |
|
2016-03-07
| ||
| 17:37 | Add the SQLITE_CONFIG_STMTJRNL_SPILL option for sqlite3_config(). file: [884d4c7e] check-in: [b6c42024] user: drh branch: trunk, size: 12442 | |
|
2016-02-15
| ||
| 00:34 | Improvements to the application-defined function mechanism so that it is more compact and runs faster, especially when the application defines thousands of new SQL functions. file: [ded7b97e] check-in: [3201fbcc] user: drh branch: many-app-functions, size: 11861 | |
|
2015-12-30
| ||
| 16:51 | Changes to the way that the default BINARY collating sequence is recorded result in a slightly smaller and slightly faster executable. More work could be done to make this cleaner. file: [bd5a0af3] check-in: [2081d757] user: drh branch: trunk, size: 11871 | |
|
2015-09-11
| ||
| 05:06 | Enhance mutex initialization to prevent possible race conditions between sqlite3_initialize() and sqlite3_config(). Also, re-check sqlite3GlobalConfig.isInit after the mutex subsystem has been initialized. file: [d8241636] check-in: [f6a8f577] user: mistachkin branch: mutexInitCmpSwap, size: 11823 | |
|
2015-07-07
| ||
| 21:14 | Add a compile-time constant for configuring the default pagecache setup. file: [508e4087] check-in: [ad5fdfba] user: drh branch: pcache-bulk-local, size: 11780 | |
|
2015-07-06
| ||
| 18:54 | Enhance separate pcache1 to allocate a block of pages from heap on startup, if possible, for a 5.2% performance improvement. file: [32c0ebfd] check-in: [aa7341c8] user: drh branch: pcache-bulk-local, size: 11777 | |

| 14:17 | Repurpose the SQLITE_TESTCTRL_FAULT_INSTALL test-control to register a callback to be invoked by sqlite3FaultSim(). That test-control has been unused since 2008-06-20 and was never used in any official release. file: [1e4bd956] check-in: [0d43a7ad] user: drh branch: trunk, size: 10896 | |
|
2014-05-03
| ||
| 11:22 | Add the SQLITE_DEFAULT_WORKER_THREADS compile-time option. Fix a NULL-pointer dereference that can occur following OOM. file: [b7943ff4] check-in: [e0dea89b] user: drh branch: threads, size: 10722 | |
|
2014-04-01
| ||
| 15:38 | Even if compile time option SQLITE_MAX_WORKER_THREADS is set to one or greater, set the default number of worker threads to zero. Distribute data more evenly between threads in sqlite3VdbeSorterWrite() to improve performance when sorting large amounts of data. Add new test file sort2.test. file: [deadd872] check-in: [643c86a0] user: dan branch: threads, size: 10717 | |
|
2014-03-31
| ||
| 19:57 | Add the SQLITE_MAX_WORKER_THREADS compile time option. And the SQLITE_CONFIG_WORKER_THREADS sqlite3_config() switch. file: [57d9dd92] check-in: [2774710d] user: dan branch: threads, size: 10717 | |
|
2013-11-29
| ||
| 15:06 | Add a new sqlite3_test_control() that indicates that database files are always well-formed. Use this during testing to enable assert() statements that prove conditions that are always true for well-formed databases. file: [1d7bb7ea] check-in: [15e4f63d] user: drh branch: trunk, size: 10673 | |
|
2013-04-15
| ||
| 17:03 | Refactoring the mmap interface. The controlling pragma is now "mmap_size" instead of "mmap_limit". Also change SQLITE_CONFIG_MMAP_LIMIT and SQLITE_FCNTL_MMAP_LIMIT to SQLITE_CONFIG_MMAP_SIZE and SQLITE_FCNTL_MMAP_SIZE, respecctively. The default mmap_size is now always 0, meaning that memory mapped I/O is off by default. There is a new compile-time option SQLITE_MAX_MMAP_SIZE that determines a hard upper bound on the mmap_size. Setting SQLITE_MAX_MMAP_SIZE to zero disables the memory-mapped I/O logic and causes it to be omitted from the build. An extra argument is added to SQLITE_CONFIG_MMAP_SIZE that can optionally lower the SQLITE_MAX_MMAP_SIZE at start-time. The SQLITE_MAX_MMAP_SIZE is zero for platforms where we know that it does not work, meaning that it cannot be turned on by mistake on those platforms. file: [5caf4dea] check-in: [ea1404a1] user: drh branch: trunk, size: 10625 | |
|
2013-04-01
| ||
| 22:38 | Add the SQLITE_CONFIG_MMAP_LIMIT configuration option for overriding the SQLITE_DEFAULT_MMAP_LIMIT compile-time setting. Enhance "PRAGMA mmap_limit" so that without a specific database name, it sets the limit on all database files and changes the default for any future databases that might be added using ATTACH. file: [d2494a1c] check-in: [78141d0a] user: drh branch: experimental-mmap, size: 10605 | |
