2014-09-19
| ||
| 16:02 | Updates to comments. No code changes. (check-in: 9b42c3da6b user: drh tags: trunk) | |
| 15:28 | The OP_Column opcode runs faster and is smaller by manually in-lining the code that persists string values in the output register. (check-in: 36b613ccf0 user: drh tags: trunk) | |
| 15:06 | Add extra tests for the ota extension. (check-in: 1e468fe1e4 user: dan tags: ota-update) | |
| 04:42 | Add the sqlite3VdbeMemClearAndResize() function. Fix a sorting-index prefilter problem. (check-in: 987a7a2119 user: drh tags: trunk) | |
| 02:01 | Make sure that the sorting-index pre-filter recognizes that a rowid reference might be sortable. This fixes a performance regression. (Closed-Leaf check-in: 72727b68cd user: drh tags: Cplusplus-comment) | |
| 00:43 | Add the sqlite3VdbeMemClearAndResize() interface to be used in place of sqlite3VdbeMemGrow(). A C++ style comment was left in this check-in by mistake, and so it has been moved into a branch to avoid problems in any future bisects on windows. (check-in: 5b9b898779 user: drh tags: Cplusplus-comment) | |

| 21:25 | Add the Mem.szMalloc element to the Mem object and use it to keep track of the size of the Mem.zMalloc allocation. (check-in: 9c09ac353d user: drh tags: trunk) | |
| 18:55 | Correct typos in comments. No changes to code. (check-in: 5587993211 user: mistachkin tags: trunk) | |
| 17:57 | Update the ota extension to support SQLITE_ENABLE_8_3_NAMES builds. (check-in: 718da6de87 user: dan tags: ota-update) | |
| 17:52 | Merge the Mem.r value into the MemValue union as Mem.u.r. Hence, a Mem can now store an integer or a real but not both at the same time. Strings are still stored in a separate element Mem.z, for now. (check-in: 4c8c89d7e6 user: drh tags: trunk) | |
| 16:38 | Use quotes instead of angle-brackets to include sqlite3.h from sqlite3ota.h. (check-in: fce9c6ccf1 user: dan tags: ota-update) | |
| 16:28 | Performance improvement for affinity transformations on comparison operators. (check-in: d7afdcbac2 user: drh tags: trunk) | |

| 15:22 | Add new file ext/ota/README.txt, containing notes regarding the implementation of the ota extension. (check-in: 3c6e1cbb4b user: dan tags: ota-update) | |
| 14:48 | Add an API to query an ota handle for the total number of key/value operations performed so far. (check-in: e3943fa7bb user: dan tags: ota-update) | |
| 14:36 | Since numeric affinity is the most common case, check it first. Interchange the NONE and TEXT affinity codes for easier checking of no affinity. (check-in: 4ef4c9a7c8 user: drh tags: trunk) | |
| 11:31 | Merge latest trunk changes with this branch. (check-in: 67ea2979d5 user: dan tags: ota-update) | |

| 02:20 | Fix harmless warnings on 32-bit MSVC builds. (check-in: 5192f964b2 user: drh tags: trunk) | |
| 01:50 | Make sure of the strchrnul() library function on platforms where it is available. (check-in: ef1aa10b7f user: drh tags: trunk) | |
| 01:29 | Merge micro-optimizations into trunk after fixing the build on MSVC. Performance now shows 7.58% faster than the 3.8.6 release on x64 with gcc 4.8.1 and -Os. (check-in: 1de558bcb1 user: drh tags: trunk) | |
| 01:21 | Fix compiler warnings and change the nullMem structure initializer into a format that MSVC can understand. (Closed-Leaf check-in: 163bfae858 user: drh tags: micro-optimizations) | |
|
2014-09-17
| ||

| 19:05 | Fix an unintialized variable problem in sqlite3ota.c. (check-in: 0126860751 user: dan tags: ota-update) | |
| 16:41 | In the Mem object, stop requiring that Mem.xDel be NULL when the MEM_Dyn bit is clear. Also reduce the amount of initialization of Mem objects. All for a small size reduction and performance increase. (check-in: fdddb477c8 user: drh tags: micro-optimizations) | |
| 15:20 | Add tests and fixes for "PRAGMA ota_mode". (check-in: 39df35c4ac user: dan tags: ota-update) | |

| 20:05 | Make sure registers are cleared properly prior to being used to store the result of an OP_Column operator. (check-in: 78fb8838d8 user: drh tags: micro-optimizations) | |
| 20:02 | Clarify the effects of the pager_ota_mode pragma. Add tests and fixes for the same. (check-in: decaccc37c user: dan tags: ota-update) | |
| 18:22 | Simplification of the OP_Column logic for the case of rows with overflow. (check-in: f73678038d user: drh tags: micro-optimizations) | |
| 14:55 | Remove an unused parameter from sqlite3VdbeIdxRowid(). This is cosmetic only as the C-compiler optimizers were already omitting this parameter on amalgamation builds. (check-in: a10a6bba49 user: drh tags: micro-optimizations) | |
| 14:37 | Reduce the number of arguments to RecordCompare functions from 4 to 3, resulting in a small performance increase. (check-in: 8239c35aed user: drh tags: micro-optimizations) | |
| 14:16 | Reorder the elements of the Mem object for a small size reduction and performance improvement. Moved into a branch because MSVC is unable to handle named structure initializer on nullMem. (check-in: 0be3019ed7 user: drh tags: micro-optimizations) | |
| 13:30 | Changes to sqlite3VdbeRecordUnpack() to make it slightly smaller and faster. (check-in: 8fb90da77c user: drh tags: trunk) | |
| 03:24 | Performance improvement to the sqlite3MemCompare() routine by factoring out sqlite3BlobCompare(). (check-in: 20ed2321b0 user: drh tags: trunk) | |

| 15:34 | Merge latest trunk changes with this branch. (check-in: 55b8011d5b user: dan tags: ota-update) | |
| 15:22 | Have sqlite3ota.c use grave accents instead of double-quotes to enclose identifiers in generated SQL. To avoid having the SQL engine substitute a literal string if a column reference cannot be resolved. (check-in: 79f2418429 user: dan tags: ota-update) | |
| 14:59 | Remove the EXPENSIVE_ASSERTS in pcache.c having to do with the pSynced field of the Pcache object, as they are incorrect, as revealed by recent pcache enhancements. (check-in: 69a6456077 user: drh tags: trunk) | |
| 14:54 | Ensure the correct collation sequences are used when sorting data in sqlite3ota.c. (check-in: 473a72d700 user: dan tags: ota-update) | |
| 14:46 | Do not flatten aggregate subqueries that contain min() or max() functions so that if the min()/max() are discarded by the outer query, they still function and cause non-aggregate expression to be evaluated on the minimal or maximal row. (check-in: 0bdf1a086b user: drh tags: trunk) | |
| 12:18 | Have the sqlite3_index_writer() VMs check that the final values of records inserted into indexes on rowid tables are integers. (check-in: cca376bff3 user: dan tags: ota-update) | |
| 11:14 | Adjust comments to show that subquery flattening restriction (10) was removed from the code back in 2005. This is a comment change only. (check-in: 4ff0eb96bc user: drh tags: trunk) | |
| 10:44 | Add OP_Affinity opcodes to the VMs generated by sqlite3_index_writer(). (check-in: b9b38cb8e2 user: dan tags: ota-update) | |
|

| 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) | |

| 14:40 | 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) | |

| 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) | |

| 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) | |

|
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) | |
