| 23:34 | Fix an issue with sqlite3_bind_text64() with the SQLITE_UTF16 encoding parameter. Remove some unreachable code from the text64() and blob64() implementation. (check-in: 34292b084e user: drh tags: trunk) | |
| 18:44 | Add new APIs that take 64-bit length parameters: sqlite3_malloc64(), sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_bind_text64(), sqlite3_result_blob64(), and sqlite3_result_text64(). Add the sqlite3_msize() interface. Internal memory allocation routines now use 64-bit unsigned length parameters for safety. Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a integer overflow problem. (check-in: 7e4978c003 user: drh tags: trunk) | |
| 17:27 | Add the SQLITE_USER_AUTHENTICATION extension to the trunk. This extension is disabled by default. Special compilation procedures are need to enable it. (check-in: 65884d4f81 user: drh tags: trunk) | |
| 17:14 | Clean up some #includes in the extension API implementation. (Closed-Leaf check-in: b149ef5c63 user: drh tags: user-auth) | |
| 16:36 | Suppress the potential schema error that occurs when a non-user-auth SQLite library tries to parse the sqlite_user table definition in a user-auth database. (check-in: cda33c1ef3 user: drh tags: user-auth) | |
| 16:19 | Enhance the sqlite3_user_add() interface to initialize the user authentication logic. Add test cases for the extra argument on the end of the authorizer callback. (check-in: 842c6da8f1 user: drh tags: user-auth) | |
| 15:25 | All interfaces working and tested. (check-in: 96ea5c0b3c user: drh tags: user-auth) | |
| 14:56 | Get the sqlite3_user_delete() interface working. (check-in: 974a9c6558 user: drh tags: user-auth) | |
| 14:40 | Fix the sqlite3_user_change() interface so that it does allow a non-admin user to change their own password. (check-in: 52d440c7e1 user: drh tags: user-auth) | |
| 14:01 | Move user authentication blocking from sqlite3_prepare() over to the table lock generator, thus allowing SQL statements (like "PRAGMA locking_mode") that do not touch database content to run prior to authentication. (check-in: 70121e7cf8 user: drh tags: user-auth) | |
| 13:44 | Add support for the extra parameter on the sqlite3_set_authorizer() callback and support for failing an ATTACH with an authentication-required database using bad credentials. The extension is now feature complete, but much testing and bug-fixing remains. (check-in: 596e728b0e user: drh tags: user-auth) | |
| 00:27 | Reorder parameters on the sqlite3_user_*() interfaces for consistency. Add the first TCL test cases. (check-in: 2f6d8f32ee user: drh tags: user-auth) | |
|

| 22:46 | Complete the implementation of the various APIs. Fix several problems. This is another incremental check-in that does not completely work. (check-in: 4eaaa7fa87 user: drh tags: user-auth) | |
| 19:01 | Add the ".user" shell command and implement the sqlite3_user_add() routine. Incremental check-in. The code compiles but does not work. (check-in: a0455f9deb user: drh tags: user-auth) | |
| 17:34 | Further ideas on user authentication. Not yet working code. (check-in: c8171ecd0d user: drh tags: user-auth) | |
|
2014-09-09
| ||
| 20:30 | Change the name of the _texte64() interfaces to just _test64(), without the "e". (Closed-Leaf check-in: 6ab76c5fed user: drh tags: 64-bit-lengths) | |
| 18:41 | Add new interfaces to the loadable extension mechanism. (check-in: 18d80cbc59 user: drh tags: 64-bit-lengths) | |
| 17:27 | Add new APIs that take 64-bit length parameters: sqlite3_malloc64(), sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_bind_texte64(), sqlite3_result_blob64(), and sqlite3_result_texte64(). Internal memory allocation routines also now use 64-bit unsigned length parameters for safety. Also add the sqlite3_msize() interface. Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a integer overflow problem. (check-in: 94954850cf user: drh tags: 64-bit-lengths) | |
| 14:47 | Non-working preliminary implementation attempts on user authentication. (check-in: 8440f093ba user: drh tags: user-auth) | |

| 16:52 | Merge latest trunk changes with this branch. (Closed-Leaf check-in: 9dca7ce557 user: dan tags: android-large-filles) | |
| 16:49 | Fixes to os_unix.c to support database (and other) files larger than 2GiB. (check-in: e7fae33c07 user: dan tags: android-large-filles) | |
| 16:39 | Fix typos in comments. No code changes. (check-in: e62aab5e92 user: peter.d.reid tags: trunk) | |
| 03:38 | Do not record a page-size change if the attempt to change the page size failed due to an OOM error. (check-in: 4d4fb197dc user: drh tags: trunk) | |
| 03:16 | Add the sqlite3_memdebug_title_count global variable, used during debugging to count the number of invocations of test_memdebug_settitle. By examining this variable in the debugger after a segfault, one can then set a breakpoint on test_memdebug_settitle that will fire just before the problem. (check-in: 27e3ca3e0f user: drh tags: trunk) | |
| 02:00 | Fix a couple of typos in comments. No changes to code. (check-in: a758465e3c user: mistachkin tags: trunk) | |
| 01:35 | Query planner heuristic update: When doing a full table scan on a table that has an equality constraint on an unindexed column, do not allow the estimated number of output rows to be greater than half the total number of rows in the table. (check-in: 73954f93c4 user: drh tags: trunk) | |
|
2014-09-05

| 11:03 | Avoid calling sqlite3OsFetch() on a file-handle for which the xFetch method is NULL. (check-in: 071f7f2dec user: dan tags: ota-update) | |
|
2014-09-03
| ||
| 19:30 | Split part of "PRAGMA ota_mode" off into "PRAGMA pager_ota_mode". This allows some specialized custom VFS implementations to intercept and implement the expected pager-related effects of this pragma. (check-in: 209f672e58 user: dan tags: ota-update) | |
| 08:25 | Add a command line program that uses the extension. This serves as example code and is also useful for performance testing. (check-in: ffa1524ef2 user: dan tags: ota-update) | |
|
2014-09-02

|
2014-09-01
| ||
| 23:06 | Update comments in the ANALYZE command that describe how the Stat4Accum objecct is passed around within the VDBE. No changes to functional code. (check-in: 9779c7a9eb user: drh tags: trunk) | |
| 22:34 | Avoid a confusing (though correct) argument to the sqlite3_result_blob() function in the implementation of ANALYZE. (check-in: 4cae93f8ae user: drh tags: trunk) | |
| 19:29 | For sqlite3_win32_is_nt(), assume WinRT is NT-based and revise #ifdef ordering to prefer the ANSI version of GetVersionEx, when available. (check-in: be0a037244 user: mistachkin tags: trunk) | |
| 18:21 | Tweak the documentation for SQLITE_LIMIT_WORKER_THREADS. No changes to executable code. (check-in: 672e7387b1 user: drh tags: trunk) | |
| 17:36 | Add support for using separate worker threads to speed large sorts. The SQLITE_MAX_WORKER_THREADS and SQLITE_DEFAULT_WORKER_THREADS compile-time options and the SQLITE_LIMIT_WORKER_THREADS argument to sqlite3_limit() and the "PRAGMA threads=N" pragma are added. (check-in: b1c0f0bc1b user: drh tags: trunk) | |
|
2014-08-29
| ||
| 19:06 | Disable worker threads when SQLITE_THREADSAFE=0. Set the default compile-time maximum number of worker threads to 8 and honor the SQLITE_DEFAULT_WORKER_THREADS compile-time constant (which defaults to 0). (Closed-Leaf check-in: 33fa041049 user: drh tags: threads) | |
| 18:06 | Fix the speedtest1.c test program to set the worker thread count using the threads pragma. (check-in: 2ab4b5adc6 user: drh tags: threads) | |
| 16:20 | Add SQLITE_LIMIT_WORKER_THREADS for controlling the maximum number of worker threads. (check-in: 1b598c68f3 user: drh tags: threads) | |
| 14:40 | Merge recent performance enhancements from trunk onto the threads branch. (check-in: 35c44a3c73 user: drh tags: threads) | |
|
2014-08-25
| ||
| 23:44 | Remove the SQLITE_CONFIG_WORKER_THREADS configuration parameter. The number of worker threads in the sorter is now determined only by the PRAGMA threads=N setting. (check-in: e3305d4b4e user: drh tags: threads) | |
| 22:43 | Merge the CAST operator enhancements from trunk. (check-in: 6c8f86e4e0 user: drh tags: threads) | |
| 22:37 | Add an assert() and five testcase() macros to the OP_Cast opcode implementation to help verify that it is fully tested. (check-in: af364cce9d user: drh tags: trunk) | |
| 21:11 | Minor changes to the CAST logic to make it more testable. (check-in: 1ad70ec550 user: drh tags: trunk) | |
| 20:21 | Test cases added for using unary "+" and CAST operators on the RHS of range constraints and verifying that STAT3/4 can use those constraints. (check-in: 42505e5a81 user: drh tags: trunk) | |
| 20:11 | Allow CAST expressions and unary "+" operators to be used in the DEFAULT argument of an ALTER TABLE ADD COLUMN and to be understand on the RHS of range constraints interpreted by STAT3/4. This involves a rewrite of the implementation of the CAST operator. (check-in: 91d8a8d0b7 user: drh tags: trunk) | |
| 18:29 | In cases where stat4 data is available but cannot be used because the rhs of a range constraint is too complex a expression, fall back to using the default estimates for number of rows scanned. (check-in: e06dc6f0c3 user: dan tags: trunk) | |
| 15:13 | Query or change the maximum number of worker threads allowed on each database connection separately using the "PRAGMA threads" command. (check-in: 29c5e8a7c9 user: drh tags: threads) | |
| 13:27 | Merge the recent performance enhancements implemented on trunk into the threads branch. (check-in: dfdc900f5d user: drh tags: threads) | |
| 11:33 | Remove the pager_lookup() function since it is redundant with sqlite3PagerLookup(). (check-in: 54164ce47c user: drh tags: trunk) | |
| 11:20 | Change the name of the VdbeMemRelease() macro to VdbeMemReleaseExtern() to more accurately reflect what it does. Performance enhancement to the sqlite3VdbeMemRelease() function. (check-in: 3ca5846da7 user: drh tags: trunk) | |
|
2014-08-24
| ||
| 02:53 | The sqlite3VdbeChangeEncoding() routine goes about 3x faster if the sqlite3VdbeMemTranslate() subroutine is not inlined. (check-in: 0c7e1b875a user: drh tags: trunk) | |
| 01:32 | Patch the sqlite3PagerWrite() method in the Pager to run a bit faster. (check-in: c63311e2f3 user: drh tags: trunk) | |

| 23:15 | Faster implementation of pcache1Fetch() (check-in: 0371cc3bb0 user: drh tags: trunk) | |
| 20:25 | Faster implementation of the sqlite3ApiExit() routine. (check-in: bd41d394d4 user: drh tags: trunk) | |
| 19:42 | Another memory allocator performance optimization. (check-in: 6da6f46d0c user: drh tags: trunk) | |
| 19:08 | Fix a variable-declaration after code problem in btree.c. Harmless in GCC and CLANG but unacceptable for MSVC. (check-in: 45abd5c0ba user: drh tags: trunk) | |
| 19:04 | Changes to sqlite3ScratchMalloc() that make the entire memory allocation interface a little faster and about 100 bytes smaller. (check-in: f83daa16f6 user: drh tags: trunk) | |
| 18:17 | Make the implementation of the sqlite3_aggregate_context() interface faster for second an subsequent invocations. This helps all aggregate functions to perform better. (check-in: 802148f311 user: drh tags: trunk) | |

|
2014-08-22
| ||
| 23:33 | Another performance tweak: Split the sqlite3BtreeCursorHasMoved() routine into two with the second routine named sqlite3BtreeCursorRestore(). The first now only reports whether or not the cursor has moved and the second tries to restore the cursor. This allows the sqlite3VdbeCursorMoveto() routine to be refactored to avoid stack pointer movements, for a noticable performance gain. (check-in: ce123b5c59 user: drh tags: trunk) | |
| 22:26 | Factor the saveAllCursors() routine of btree.c into two separate routines, for a noticable performance improvement. (check-in: 3eb0843903 user: drh tags: trunk) | |
| 21:58 | Performance enhancements in the b-tree mutex logic. (check-in: 8914530644 user: drh tags: trunk) | |
| 20:35 | Combine the pcacheAddToDirtyList() and pcacheRemoveFromDirtyList() routines into a single pcacheManageDirtyList() routine. The resulting binary code is slightly faster and a few bytes smaller. (check-in: 6bcf1af6a4 user: drh tags: trunk) | |
| 18:48 | Performance enhancement in sqlite3PutVarint(). (check-in: a929be5519 user: drh tags: trunk) | |
| 18:00 | Split the sqlite3Error() routine into sqlite3Error() and sqlite3ErrorWithMsg(), for a slight size reduction and performance increase. (check-in: cf561d1f0b user: drh tags: trunk) | |
| 15:40 | Performance improvement in the printf() logic by avoiding unnecessary stack pointer movement. (check-in: f7f2160db0 user: drh tags: trunk) | |
| 15:19 | Improve the performance and reduce the size of the sqlite3VdbeSerialGet() routine by avoiding the use of stack. (check-in: ebc10e46c1 user: drh tags: trunk) | |

| 14:34 | Get the sqlite3VdbeSerialGet() routine to run faster by avoiding the use of local variables. (check-in: 8267d82174 user: drh tags: experimental) | |
| 13:22 | Change a while-loop into a do-loop in sqlite3VdbeSerialPut() for a small size reduction and performance improvement. (check-in: 750bb0a096 user: drh tags: trunk) | |
| 11:11 | Enhance the spellfix extension with the ability to specify a rowid when inserting new rows. (check-in: 369c480cda user: drh tags: trunk) | |

| 23:38 | Enhancements to skip-scan such that it is operable when a middle column of an index is skipped while the left-most column is constrained in the WHERE clause. (check-in: bc985caa78 user: drh tags: trunk) | |
| 18:43 | A small performance improvement in freeSpace() by special-casing the relatively common case of an empty freelist. (check-in: 49f44d355f user: drh tags: trunk) | |
| 17:56 | Reimplement the freeSpace() routine in btree.c so that it runs faster. (check-in: fe4fd014b4 user: drh tags: trunk) | |
