| 03:09 | Add new interfaces sqlite3_result_pointer(), and sqlite3_value_pointer() and use them to transfer the eponymous FTS3 column pointer to the snippet() and offsets() routines. This changes is inspired by check-in [72de49f2] but is new implementation, not a cherry-pick. Leaf check-in: f0f49224 user: drh tags: branch-3.7.11 | |
|
2015-05-21
| ||
| 02:24 | Silently ignore any attempt to add a prefix index for prefixes zero bytes in size to an fts3/4 table. Or any prefix index size so large that it overflows a 32-bit signed integer. Cherrypick [ad4b19d2ac0889a] check-in: 000197cc user: drh tags: branch-3.7.11 | |
| 02:20 | Ensure that tables names are dequoted exactly once by the trigger logic. Cherrypick [59e92bd9521f1e8] and [9d887b92f8086961e]. check-in: 9e3f64a4 user: drh tags: branch-3.7.11 | |
| 02:07 | When parsing the schema, ignore any SQL that does not begin with "CREATE". Cherrypick of [d3c00d61581c] with additional changes. check-in: 09784f37 user: drh tags: branch-3.7.11 | |

|
2014-04-24
| ||
| 13:20 | Add sqlite3_log() diagnostic messages for a specific type of corruption where the file size is reported to be too small relative to the size in the header.

| 04:22 | Lower the threshold for using skip-scan from 50 to 18, based on experiments that show that 18 is the approximate break-even point for a variety of schemas. check-in: 83c0bb99 user: drh tags: trunk | |
| 04:00 | Avoid using the GetVersionEx functions if they are considered deprecated. check-in: afdca299 user: mistachkin tags: trunk | |

|
2013-11-26
| ||
| 23:27 | Make sure the update hook is not invoked for WITHOUT ROWID tables, as the documentation specifies. This bug was found while adding requirements marks, so a few extraneous requirements marks are included in this check-in. check-in: 0978bac6 user: drh tags: trunk | |
| 22:46 | Add requirements test cases for determining when an expression is true and when it is false. check-in: 838654e5 user: drh tags: trunk | |
| 21:18 | Changing the CAST behavior of REAL values actually changed a documented requirement. So we also have to change the requirement evidence text to match. check-in: d84aa44e user: drh tags: trunk | |
| 18:22 | Reduce the amount of code used to implement OP_SeekGe and similar. check-in: 8b12a15a user: dan tags: trunk | |

| 16:20 | Do not try to run the atof1.test test script on ARM hardware which lacks the "long double" type. check-in: fafca560 user: drh tags: trunk | |
| 15:45 | Change the REAL-to-INTEGER casting behavior so that if the REAL value is greater than 9223372036854775807.0 then it is cast to the latest possible integer, 9223372036854775807. This is sensible and the way most platforms work in hardware. The former behavior was that oversize REALs would be cast to the smallest possible integer, -9223372036854775808, which is the way Intel hardware works. check-in: 6f53fc71 user: drh tags: trunk | |
| 01:13 | Fix comment. check-in: 8364af39 user: mistachkin tags: winHdr | |

|
2013-11-25
| ||
| 23:42 | Add SQLITE_CONFIG_WIN32_HEAPSIZE option to configure the maximum isolated heap size on Windows. check-in: 914e6c9d user: mistachkin tags: trunk | |
| 22:24 | Change a while-loop into a do-loop in sqlite3VdbeRecordCompare() and add an assert() to verify that the do-loop really is appropriate. This gives about a 10% performance boost in that routine, or a 0.9% boost overall. check-in: 011a6be4 user: drh tags: trunk | |
| 21:49 | Clarify docs for the SQLITE_CONFIG_WIN32_HEAPSIZE option. Closed-Leaf check-in: 51e87607 user: mistachkin tags: winHeapSize | |
| 21:41 | Remove a NEVER() from a branch that is now reachable during OOM faults. check-in: 18bdcb05 user: drh tags: trunk | |
| 20:50 | Optimizations to the sqlite3BtreeMovetoUnpacked() routine in storage engine making it about 17.8% faster, which in turn makes SQLite over 1.2% faster overall. check-in: 032e8993 user: drh tags: trunk | |
| 20:14 | Return an SQLITE_CORRUPT error if the content size field of a table record extends off the end of a page. Closed-Leaf check-in: b48c4e40 user: drh tags: btree-optimization | |
| 17:38 | Uses shifts rather than division for arithmetic on the cell indices, since those indices are always non-negative. check-in: 5bf2a3fe user: drh tags: btree-optimization | |
| 16:52 | Optimize the skipping of the payload size field when doing a binary search for a rowid. check-in: 55e5bfa2 user: drh tags: btree-optimization | |
| 16:23 | Arrange for sqlite3BtreeMovetoUnpacked() to always leave the cursor cell parse cache invalidated. This fixes issues with previous check-ins on this branch and also runs faster. check-in: a7467560 user: drh tags: btree-optimization | |
| 15:01 | More optimizations to sqlite3BtreeMovetoUnpacked(). But there are failures in TH3. Committing this intermediate state to facilitate bisecting. check-in: f80497be user: drh tags: btree-optimization | |
| 14:10 | More improvements to sqlite3BtreeMovetoUnpacked() performance. check-in: 88680698 user: drh tags: btree-optimization | |
| 09:37 | Correct line-endings in the new header file. check-in: 94219b9f user: mistachkin tags: winHdr | |
| 09:36 | Initial work on isolating usage of the Windows header file. check-in: 0d42c6b8 user: mistachkin tags: winHdr | |
| 02:38 | Performance improvements in sqlite3BtreeMovetoUnpacked(). check-in: d0fb7ace user: drh tags: btree-optimization | |
|
2013-11-24
| ||
| 23:18 | Better support for UTF-8 paths on Cygwin. Closed-Leaf check-in: 484162b6 user: mistachkin tags: cygUtf8 | |
| 01:14 | Add the --scratch parameter to speedtest1. Improved error messages when misconfiguring memory parameters in speedtest1. check-in: 8f3c767a user: drh tags: trunk | |
| 00:46 | The MEMSYS5 algorithm does not have to return the block with the lowest address. Any block of the appropriate size will do. Use the first block found on the freelist for the appropriate size for a performance improvement. check-in: 12e612e8 user: drh tags: trunk | |
|
2013-11-23
| ||
| 22:45 | A much simpler fix is to simply change MEMSYS5 so that it takes any free block of the appropriate size (the first on the list of free blocks) rather than searching for the one with the smallest address. This is also faster than using the min-heap algorithm. Need to research to verify that the allocator still satisfies the Robson proof, however. Closed-Leaf check-in: 8191b512 user: drh tags: memsys5-performance | |
| 21:30 | Use a heap-based primary queue rather than a linked list to store the available free blocks of each size in MEMSYS5, since this provides faster access to the first available block. Closed-Leaf check-in: 7d2cdfad user: drh tags: memsys5-performance | |
| 21:29 | Add newlines at the end of some error messages in speedtest1. check-in: 6b98f0af user: drh tags: trunk | |
| 11:45 | Report errors from sqlite3_exec() and sqlite3_config() in speedtest1. Fix a bug in the main testing logic that was found by these error reports. check-in: 659f1a98 user: drh tags: trunk | |
| 04:32 | Fix the order of parameters to SQLITE_CONFIG_PAGECACHE in the speedtest1.exe program. check-in: dbe85ef6 user: drh tags: trunk | |
| 04:22 | Adjust MSVC makefile to avoid using forward slashes in file names. check-in: facf6dea user: mistachkin tags: trunk | |

| 21:59 | Changes some offset and amount parameters from "int" to "u32" to avoid harmless signed/unsigned comparison warnings. check-in: 4e8c5d07 user: drh tags: trunk | |
| 21:40 | Modify wordcount so that timer information appears on standard error instead of standard output. Rename the run-wordcount.bash script to run-wordcount.sh and simplify it so that it stands a better chance of running on non-GNU systems. check-in: 586c11ed user: drh tags: trunk | |
| 21:23 | Do not reuse factored constants that might have had their encodings changed. check-in: 487f2036 user: drh tags: trunk | |

| 19:05 | Remove a test from sqlite3VdbeMemFromBtree() which was unnecessary, and after the recent OP_Column refactoring, unreachable. check-in: 23667f3b user: drh tags: trunk | |
| 17:24 | Make sure the OP_Next and OP_NextIfOpen opcodes are numbered close together for efficiency in switch() statements. OP_Prev and OP_PrevIfOpen too. check-in: d4ccf0f5 user: drh tags: trunk | |

| 01:04 | Reduce the size of VdbeCursor again, this time without a performance hit. Closed-Leaf check-in: 93393993 user: drh tags: OP_Column-refactor | |
| 00:10 | Unpack some fields, adding some space back to the VdbeCursor object, in order to help the code to run a little faster. check-in: f8d5efcd user: drh tags: OP_Column-refactor | |
