2017-07-21
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)
01:04
Do not allow virtual table constructors to be called recursively. Cherrypick [0a72726da21581ab] (check-in: 0f0694e4 user: drh tags: branch-3.7.11)
00:50
Add the ".open" command to the command-line shell. Cherrypick from [21eccb919441]. (check-in: a71e2a72 user: drh tags: branch-3.7.11)
2014-10-02
09:27

Experimental changes to use GetFileInformationByHandle instead of GetFileSize in the Win32 VFS. (Closed-Leaf check-in: d22c8142 user: mistachkin tags: filesize-debug)
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.

16:28
Have the OP_NoConflict opcode set the VdbeCursor.seekResult variable. This speeds up subsequent OP_Insert and OP_IdxInsert opcodes. (check-in: 47455500 user: dan tags: omit-rowid)
14:52
Use ansi escape codes to use different colored text for opcode names in the output of [explain_i]: Red for opcodes that insert or delete b-tree elements, blue for opcodes that move cursors and green for the ResultRow opcode. (check-in: 4be2b64b user: dan tags: omit-rowid)
14:36
Allocate extra stack space for UnpackedRecord objects, reducing the need to malloc for them as often, and thereby get a performance improvement. (check-in: a725a75f user: drh tags: omit-rowid)
14:05
Minor optimization to the OP_Halt opcode. (check-in: d70c7881 user: drh tags: omit-rowid)
12:56
Improved ORDER BY optimization for WITHOUT ROWID tables. (check-in: 8f1709ff user: drh tags: omit-rowid)

14:19
Add tests for updates of without-rowid tables that use non-BINARY collation sequences for the primary key columns. And a minor bugfix to the same. (check-in: 99b1fa4b user: dan tags: omit-rowid)
13:33
Standardize the error messages generated by constraint failures to a format of "$TYPE constraint failed: $DETAIL". This involves many changes to the expected output of test cases. (check-in: 54b22192 user: drh tags: omit-rowid)
01:59
Add the conflict2.test script. Fix issues discovered by this script. (check-in: 294ed337 user: drh tags: omit-rowid)

19:34
Change the "idx" name of the primary key index for WITHOUT ROWID tables in sqlite_statN statistics tables to be the name of the table rather than the fabricated index name (ex: sqlite_autoindex_xyz_1). This makes it consistent with sqlite_master table. (check-in: 4ee4d310 user: drh tags: omit-rowid)
18:46
Update the ANALYZE logic so that it works with WITHOUT ROWID tables. (check-in: 9075770e user: drh tags: omit-rowid)

17:21
Merge all changes from trunk, and disable a pair of corruption tests that are no longer valid since sqlite_master.rootpage can now be NULL for tables. (check-in: dd5d57b9 user: drh tags: omit-rowid)
17:08
Change the interface to sqlite3GenerateConstraintChecks() for improved lucidity and to fix issues in dealing with UPDATEs for WITHOUT ROWID tables. Make sure iDataCur and iIdxCur are initialized when processing DELETEs of a VIEW. UPDATE processing distinguishes between changes to ROWID and PRIMARY KEY. (check-in: c525ac56 user: drh tags: omit-rowid)
14:03
Improved VDBE comments on the constraint checker. Fix a missing write lock in the UPDATE logic. (check-in: 3bed599e user: drh tags: omit-rowid)

2013-10-31
20:34
Fix the Synopsis on OP_Concat. Added test_addop_breakpoint() during SQLITE_DEBUG. Enhanced sqlite3VdbeChangeToNoop() to omit the instruction if it is the most recent added. Continue to fix problems with UPDATE and WITHOUT ROWID. (check-in: 9b6d9e10 user: drh tags: omit-rowid)
18:49
Fix a problem in os_unix.c causing compilation failure if SQLITE_DEBUG and SQLITE_MAX_MMAP_SIZE=0 are both defined. (check-in: 090db8c8 user: dan tags: trunk)
17:38
Fix issues with quering from an auxiliary index that must refer back to the PRIMARY KEY index of a WITHOUT ROWID table. (check-in: cff1f55c user: drh tags: omit-rowid)
15:37
Improved comments and variable names in infrastructure routines of UPDATE, DELETE, and INSERT. (check-in: ad90e762 user: drh tags: omit-rowid)

Moving UPDATE towards the iDataCur/iIdxCur representation. Still not working for WITHOUT ROWID, though. (check-in: deacbd21 user: drh tags: omit-rowid)
11:15
Refactor the INSERT, DELETE, and UPDATE code generators to distinguish between the "data cursor" and the "first index cursor", which are no longer consecutive in the case of a WITHOUT ROWID table. (check-in: 1adfca60 user: drh tags: omit-rowid)
06:39
Update comments in the MSVC batch build tool. (check-in: 0414bb73 user: mistachkin tags: trunk)
06:13
Enable some more tests on Windows. (check-in: 72389c29 user: mistachkin tags: trunk)

15:52
Make sure KeyInfo objects on multi-column indices of WITHOUT ROWID tables have the correct nField and nXField values. Also, add the SQLITE_ENABLE_MODULE_COMMENT compile-time option and the VdbeModuleComment() macro and use it to label entry and exit points of some key routines. (check-in: 6d9af606 user: drh tags: omit-rowid)
13:46
In the P4 column of the EXPLAIN listing, abbreviate "keyinfo" as just "k" and "BINARY" as just "B". (check-in: 72d45eb7 user: drh tags: omit-rowid)
12:43
Enhance the timer in the shell to show wall-clock time in addition to user and kernel CPU time. (check-in: 908e2c21 user: drh tags: trunk)
12:30
Have the shell ".timer on" command cause the shell to report wall-clock time for each query (as well as user and system CPU time). (Leaf check-in: 5530cdc4 user: dan tags: shell-wall-clock)
03:25
Add the "Esri Spatially-Enabled Database" file format to the magic.txt file. (check-in: 8530a18f user: drh tags: trunk)

Import the automatic comment generating changes from trunk. (check-in: 8bb51da1 user: drh tags: omit-rowid)
20:40
Automatically generated comments on many VDBE opcodes when in SQLITE_DEBUG mode. Comments derive from the "Synopsis:" field added to each opcode definition in vdbe.c. (check-in: 5f310c6a user: drh tags: trunk)
16:14
Improved comments on the constraint checking logic. (check-in: 141a38a7 user: drh tags: omit-rowid)

Improved "wheretrace" capabilities: Show the constraint expression if the wheretrace flag has the 0x100 bit set and if compiled with SQLITE_ENABLE_TREE_EXPLAIN. (check-in: 710a18ac user: drh tags: trunk)
2013-10-26
15:40
Work on the UPDATE and INSERT logic. This is an incremental check-in so that can switch over to trunk to work on an unrelated issue there. (check-in: 086ec2a1 user: drh tags: omit-rowid)
13:36
Replace the OP_IsUnique opcode with OP_NoConflict. This code simplification might be useful to move onto trunk even if this branch is never merged. (check-in: e6650e16 user: drh tags: omit-rowid)
00:58
Minor refactoring of variable names and fixes to comments in insert.c. (check-in: ae61a343 user: drh tags: omit-rowid)

2013-10-24
19:48
Update the interface to the sqlite3GenerateRowDelete() utility so that it is able to handle WITHOUT ROWID tables. The implementation still needs to be completed. (check-in: 85daf517 user: drh tags: omit-rowid)
15:20
Add the ".open" command to the command-line shell. (check-in: 21eccb91 user: drh tags: trunk)
14:16
Delete PRIMARY KEY index entries last. Only construct the unique prefix of an index key when deleting entries from an index. (check-in: 0e56ba69 user: drh tags: omit-rowid)
11:55
Remove an obsolete comment from the VDBE. No code changes. (check-in: 53bb070c user: drh tags: omit-rowid)
00:18
Correctly handle queries that use secondary indices of WITHOUT ROWID tables. (check-in: d8bc8595 user: drh tags: omit-rowid)
2013-10-23
23:37
Change the sqlite3OpenTable() utility to open the PRIMARY KEY index when reading a WITHOUT ROWID table. (check-in: 247f3899 user: drh tags: omit-rowid)

2013-10-22
18:01
The Index object now has nKeyCol and nColumn. nColumn is the total number of columns and nKeyCol is the number of key columns. Currently these always differ by one. Refactor aiColumn[] to be of type i16 instead of int. (check-in: a106ce86 user: drh tags: omit-rowid)
14:28
Add a procedure to handle the messy details of allocating an Index object from the heap. (check-in: 45efc94f user: drh tags: omit-rowid)
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

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

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)

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)

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)

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)

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)

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)

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)

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)

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)
