2013-10-22
| ||
| 10:23 | Extra backwards-compatibility tests verify that UNIQUE and PRIMARY KEY indices are created in the correct order. Other backwards-compatibility tests already cover this, but it does not hurt to double up. check-in: 5ca0ea2e user: drh tags: omit-rowid | |
| 01:18 | Previous refactor is not going to be helpful because implied indices must be created in the same order that they appear in the CREATE TABLE statement for backwards compatibility. This is a much smaller change to clean up a few loose ends. check-in: 824b549f user: drh tags: omit-rowid | |
|
2013-10-21
| ||
| 23:55 | Minor refactoring of the PRIMARY KEY parsing logic to facilitate enhancements. Closed-Leaf check-in: 4e69dd5f user: drh tags: omit-rowid | |
| 23:17 | Improve support for the SQLITE_OMIT_FLAG_PRAGMAS compile-time option. check-in: f1d8c3b0 user: mistachkin tags: trunk | |
| 13:15 | Drop the mutex on the multiplexor before entering the xRead VFS call. Closed-Leaf check-in: a00d2ed4 user: drh tags: multiplex-parallel-read | |
| 02:14 | Simplification of the syntax: Merely append "WITHOUT rowid" to the end of the table definition. check-in: 131cc6e1 user: drh tags: omit-rowid | |
|
2013-10-19
| ||
| 23:31 | Experimental changes toward "index only" tables. Add the ability to specify options on CREATE TABLE statements using the WITH clause modeled after PostgreSQL and SQL Server. Only the "omit_rowid" option is currently recognized and that option is currently a no-op. check-in: 0248ec5e user: drh tags: omit-rowid | |
| 16:51 | Improved header comment with better instructions on the vfslog.c extension. check-in: 4bd592c8 user: drh tags: trunk | |
| 15:07 | Fix a bug causing an "malformed database schema error" error if a temp table with the same name as an existing table that has at least one temp trigger attached to it is created. check-in: 56dca4a6 user: dan tags: trunk | |
|
2013-10-18
| ||
| 20:03 | Add the SQLITE_FCNTL_TRACE file control and generate it for OP_Trace when compiled with SQLITE_USE_FCNTL_TRACE. Update vfslog.c to make use of the new file control. Also update vfslog.c to log UNLOCK events before the fact, rather than afterwards. check-in: e801f35a user: drh tags: trunk | |
| 17:42 | Further enhance the vfslog extension to record the number of freelist pages and the first freelist page in CHNGCTR-READ and CHNGCTR-WRITE records. check-in: 08157524 user: drh tags: trunk | |
| 14:37 | In the vfslog extension for FILECONTROL records, show the pragma name for SQLITE_FCNTL_PRAGMAs and the requested size for SQLITE_FCNTL_SIZE_HINT. check-in: f0629695 user: drh tags: trunk | |
|

| 19:35 | Add implementations for the toInteger() and toReal() SQL functions. check-in: a0f7cbc0 user: drh tags: trunk | |
| 15:41 | Fix for building with SQLITE_OMIT_FOREIGN_KEY. check-in: b8b5f6c8 user: dan tags: trunk | |
| 14:30 | Update the foreign_key_check pragma so that when a parent table is undefined it is treated as an empty table. check-in: 208b259a user: drh tags: trunk | |
| 14:21 | Corrects to comments on the STAT4 implementation. check-in: e06f74d3 user: drh tags: trunk | |

| 23:39 | Merge updates from trunk. Closed-Leaf check-in: a88b5be0 user: mistachkin tags: toTypeFuncs | |
| 20:22 | Restore the index_list pragma back to its former operation. Create a new PRAGMA stats used to access the table and index widths and heights. check-in: f0cf8c85 user: drh tags: trunk | |
| 19:06 | In "PRAGMA foreign_key_check", treat missing parent tables as empty (instead of as errors). Closed-Leaf check-in: 8c13a7fd user: dan tags: fkc-missing-parent-tables | |
| 15:12 | Fix handling of "DROP TABLE" commands when "PRAGMA defer_foreign_keys=1" is set. check-in: 27001356 user: dan tags: trunk | |
| 13:16 | Add tests that demonstrate that PRAGMA defer_foreign_keys will reset to off at the conclusion of the next transaction. check-in: 67e28a11 user: drh tags: trunk | |
| 09:32 | Changes to the new initial row of PRAGMA index_list results. Closed-Leaf check-in: 0c4dd9ff user: mistachkin tags: indexList | |

2013-10-11
| ||
| 23:37 | Identify requirements text in the SQLITE_CONFIG_ documentation. Fix a typo (a duplicated word) in part of that documentation. Add some requirements marks for DETACH to the test scripts. No code changes. check-in: 1be0a3ad user: drh tags: trunk | |
| 23:02 | The split amalgamation option should be disabled by default. check-in: 7c24d22f user: mistachkin tags: trunk | |

| 20:13 | Synchronize with the trunk. check-in: 136445ba user: drh tags: sessions | |
| 17:33 | Add a rule to the main.mk makefile for building showdb. check-in: fc5552da user: drh tags: trunk | |

| 13:41 | Another fix to the hash signature algorithm in vfslog.c. check-in: 34212aa8 user: drh tags: trunk | |
| 13:38 | Fix the hash signature algorithm in vfslog.c. Add a utility program to show the hash signatures for every page of a database file. check-in: eaf4de13 user: drh tags: trunk | |
| 13:04 | Add ext/misc/vfslog.c, a VFS shim for unix that keeps a log of method calls made by SQLite. check-in: 24a827b8 user: dan tags: trunk | |
| 12:38 | Estimate row sizes for tables and indices and use those estimates during query planning. Enhance the index_info pragma to show the estimated row sizes and to show the estimated row size for the main table as well. Allow an alternative row size estimate to be specified in the sqlite_stat1 table. check-in: d27b88b8 user: drh tags: trunk | |
|
2013-10-09
| ||
| 19:07 | Make sure the correct printf format is used for type tRowcnt regardless of whether 32-bit or 64-bit row counts are specified at compile-time. Closed-Leaf check-in: e97d7d30 user: drh tags: row-size-est | |
|
2013-10-08
| ||
| 23:16 | Move a conditional inside of an #ifdef in order to make all branches reachable regardless of compile-time options used. check-in: f7cc30d4 user: drh tags: row-size-est | |
| 22:25 | Fix test cases for the new information in PRAGMA index_list. check-in: dd03be10 user: drh tags: row-size-est | |
| 20:42 | Rollback some of the previous changes in the branch such that the estimated row sizes are now only used as a tie-breaker for index scans. check-in: 65553ff3 user: drh tags: row-size-est | |
| 20:01 | Use #ifdefs to omit unused code in the columnType() routine depending on compile-time options. check-in: 3fd5e332 user: drh tags: row-size-est | |
| 18:40 | Further refinement of the idea of multiplying run-time cost estimates by the estimated row size. check-in: 18bd6ba9 user: drh tags: row-size-est | |
|
2013-10-07
| ||
| 21:49 | Fix compilation issue with MSVC. check-in: 36d64dc3 user: mistachkin tags: trunk | |
| 17:32 | Multiply all cursor step cost estimates by the estimated size of the row in bytes, in order to get the query planner ot make use of estimated row sizes. This check-in uses magic numbers in a few places (for example, estimates of the size of output rows) and needs lots of refinement. Consider this a proof-of-concept only. check-in: cb34cfe5 user: drh tags: row-size-est | |
| 16:53 | Try to remember statistics from ANALYZE using LogEst instead of u64. Leaf check-in: 8e78557a user: drh tags: log-stats | |
| 10:48 | Merge bug fixes from trunk. check-in: 1d7b2dc0 user: drh tags: row-size-est | |
| 00:36 | Restore the hexrekey pragma which was accidently deleted during the pragma refactoring. Make sure the hexkey and hexrekey pragmas do not overflow buffers with a over-length key. check-in: 0aca31e1 user: drh tags: trunk | |
|
2013-10-06
| ||
| 22:52 | Remove an incorrect debugging assert() that was accidently added during the STAT4 enhancement. check-in: 2bb7f74b user: drh tags: trunk | |
| 22:12 | Accept the sz=N parameter on table-only lines of sqlite_stat1. check-in: e9e932aa user: drh tags: row-size-est | |
|
2013-10-05
| ||
| 20:18 | Fix an issue in the test8.c test module that arises because of the change to PRAGMA index_list(). Remove an unused local variable. check-in: 029430c5 user: drh tags: row-size-est | |
| 19:18 | Completely remove the iScanRatio field. The PRAGMA index_list(TABLE) command shows the estimated row size in the forth column. It also generates a row for the table with an index name of NULL. The query planner still does not take row size estimates into account - that is the next step. check-in: 8b4aa0c7 user: drh tags: row-size-est | |
| 18:32 | Improvements to the LogEst command-line tool used to convert between ordinary numbers and the LogEst representation. check-in: 5252aeb6 user: drh tags: row-size-est | |
| 18:16 | Begin an experimental refactoring to estimate the average number of bytes in table and index rows and to use that information in query planner. Begin by renaming WhereCost to LogEst and making that type and its conversion routines available outside of where.c. check-in: 66c4a251 user: drh tags: row-size-est | |
| 02:56 | In the index_list pragma, make sure the "r" column is the same on output as it was on input in the sqlite_stat1 table. Closed-Leaf check-in: de78250a user: drh tags: index-scan-rate | |
|
2013-10-04
| ||
| 20:39 | Merge trunk changes. check-in: c6ac80ed user: drh tags: index-scan-rate | |
| 18:29 | Further refinements of the index scanning speed logic. check-in: e5d9371d user: drh tags: index-scan-rate | |
| 18:17 | If an "INSERT INTO ... SELECT" can use the xfer optimization, pass the OPFLAG_BULKCSR hint to btree cursors used to update indices. This results in a tighter key packing. check-in: 087af29e user: dan tags: trunk | |
| 15:58 | Fix test cases so that they work when the query planner uses index size estimates to determine whether or not to try an covering index scan. check-in: 2f394de8 user: drh tags: index-scan-rate | |
| 15:30 | Improved estimates of the relative speed of index scans based on declared datatypes of columns in the table. Add "r" column to PRAGMA index_info, showing the estimated relative scan rate. check-in: 07462bb6 user: drh tags: index-scan-rate | |
| 02:36 | Progress toward using the iScanRatio information on indices. Many tests are still failing. check-in: 6c352edb user: drh tags: index-scan-rate | |
| 00:00 | Make sure the count(*) optimization works correctly even when partial indices are present. Ticket [a5c8ed66cae]. check-in: 9f2f4c0a user: drh tags: trunk | |
|
2013-10-03
| ||
| 20:41 | Have FTS take advantage of "docid<?" constraints when they are present. Extend the FTS "incremental doclist" optimization so that it is used for tokens within multi-token phrases. check-in: baf8ce59 user: dan tags: trunk | |
| 20:28 | Merge latest trunk changes. Closed-Leaf check-in: 24aa20da user: dan tags: fts4-docid-range-constraints | |
| 19:27 | Allow FTS4 multi-token phrases to use a combination of in-memory and incrementally loaded doclists. This allows phrases to (partially) benefit from incremental doclists without disabling the deferred token optimization. check-in: f6819c5f user: dan tags: fts4-docid-range-constraints | |
| 19:21 | Experimental branch allowing different postulated scan rates for each index. check-in: d59d97b0 user: drh tags: index-scan-rate | |
| 15:39 | The sqlite3FixInit() routine cannot fail. So change the return type from "int" to "void". check-in: 500c5932 user: drh tags: trunk | |
| 14:08 | Rework the PRAGMA implementation to only call sqlite3ReadSchema() from a single place, based on a flag in the pragma table, rather than separately from each case which needs the schema. check-in: 8338232a user: drh tags: trunk | |
| 12:29 | Return an error if an attempt is made to create a trigger with an SQL variable embedded within it. If such a variable reference is found within a trigger definition loaded from the sqlite_master table, silently replace it with a NULL. check-in: f35f6ae3 user: dan tags: trunk | |
| 11:27 | Remove unnecessary memset() calls from test code. check-in: eec3187b user: drh tags: trunk | |
|
2013-10-02
| ||
| 20:46 | In the lemon parser generator, change all hashes to unsigned to avoid potential problems with signed integer overflow. check-in: 8d399a03 user: drh tags: trunk | |
| 08:04 | Add a test to check that the new multi-token phrase optimization is actually helping. check-in: bc3a2ed5 user: dan tags: fts4-docid-range-constraints | |
|
2013-10-01
| ||
| 20:29 | Bring some file format comments in btreeInt.h up to date. check-in: 012d54d0 user: drh tags: trunk | |
| 20:10 | Merge trunk changes with this branch. check-in: 65d9c6fa user: dan tags: fts4-docid-range-constraints | |
| 20:02 | Allow multi-token phrases to load doclists from the database incrementally. This allows queries that feature such phrases to benefit from the "docid<?" optimization. check-in: ea543f08 user: dan tags: fts4-docid-range-constraints | |
| 19:36 | Fix comments in the fast_vacuum.c demonstration program. check-in: e0db7b38 user: drh tags: trunk | |
| 19:02 | Add the "fast_vacuum.c" demonstration program to the tool/ subdirectgory. check-in: 2b60320d user: drh tags: trunk | |
