100 check-ins occurring around 7c24d22ffa1e12f3.

2013-10-23
17:39
Report an error when trying to resolve column name "rowid" in a WITHOUT ROWID table. (check-in: 36bcc9cb88 user: drh tags: omit-rowid)
16:03
Get VACUUM and the xfer optimization working with WITHOUT ROWID. (check-in: 579815fff1 user: drh tags: omit-rowid)
13:30
Some inserts and queries working for multi-column primary keys and WITHOUT ROWID. (check-in: b21d831b2a user: drh tags: omit-rowid)
01:57
Some simple inserts and queries working on WITHOUT ROWID tables. (check-in: 3f8016dee2 user: drh tags: omit-rowid)
00:32
Build internal data structures appropriately for WITHOUT ROWID tables. (check-in: 35a3606071 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: a106ce86cd 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: 45efc94f9a 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: 5ca0ea2e9b 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: 824b549f9b 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: 4e69dd5f9b user: drh tags: omit-rowid)
23:17
Improve support for the SQLITE_OMIT_FLAG_PRAGMAS compile-time option. (check-in: f1d8c3b07e user: mistachkin tags: trunk)
13:15
Drop the mutex on the multiplexor before entering the xRead VFS call. (Closed-Leaf check-in: a00d2ed49c 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: 131cc6e152 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: 0248ec5e6e user: drh tags: omit-rowid)
16:51
Improved header comment with better instructions on the vfslog.c extension. (check-in: 4bd592c8f0 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: 56dca4a65c 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: e801f35a96 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: 08157524ca 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: f062969548 user: drh tags: trunk)
2013-10-17

Changes to test code to make sure no server threads are left running after server1.test finishes. (check-in: 1086e00bca user: dan tags: trunk)
14:29
Fix an 8-byte alignment problem on the "crash test" harness (test code, not in the core) that causes problems on Sparc. (check-in: bcbc65030f user: drh tags: trunk)
14:10
Merge the latest trunk changes into the sessions branch. This merge should fix the build for WinRT. (check-in: e111e4edf9 user: drh tags: sessions)
11:58
Fix harmless macro redefinition warnings in the totype extension. (check-in: c9c1f8d670 user: drh tags: trunk)
10:43

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: 208b259ad7 user: drh tags: trunk)
14:21
Corrects to comments on the STAT4 implementation. (check-in: e06f74d32d user: drh tags: trunk)
13:21
Make subroutines sampleCopy() and valueFromExpr() have file scope. (check-in: 1660efbe46 user: drh tags: trunk)
10:46
Add a new application_id for GeoPackage version 1.0. (check-in: 98ddfe4571 user: drh tags: trunk)
2013-10-12
23:39
Merge updates from trunk. (Closed-Leaf check-in: a88b5be01e 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: f0cf8c85dc 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: 8c13a7fd73 user: dan tags: fkc-missing-parent-tables)

09:32
Changes to the new initial row of PRAGMA index_list results. (Closed-Leaf check-in: 0c4dd9fff0 user: mistachkin tags: indexList)
02:33
Fix harmless compiler warning. (check-in: 4b130f88fb user: mistachkin tags: trunk)
02:31
Permit the creation of VSIX packages for Win32. (check-in: 035d03e942 user: mistachkin tags: trunk)
00:56
Fix Unicode character encoding issues on Windows in the fts4unicode test file. (check-in: c9310c9a2b user: mistachkin tags: trunk)
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: 1be0a3adab user: drh tags: trunk)
23:02
The split amalgamation option should be disabled by default. (check-in: 7c24d22ffa user: mistachkin tags: trunk)
23:01
Enhance debugging support for the split amalgamation files when compiling with MSVC. (check-in: 8ff17c553d user: mistachkin tags: trunk)
23:01
Fix a harmless compiler warning in lemon.c. (check-in: 62959c0ce3 user: drh tags: trunk)

05:51
Fix compilation issue for WinRT. (check-in: 7a2006ca94 user: mistachkin tags: trunk)
2013-10-10
20:13
Synchronize with the trunk. (check-in: 136445ba02 user: drh tags: sessions)
17:33
Add a rule to the main.mk makefile for building showdb. (check-in: fc5552da0d user: drh tags: trunk)
15:04
Enhancements to the vfslog.c module to show all change-counter changes and to show the hostname and pid of the process that creates each log file. (check-in: af7abebeb1 user: drh tags: trunk)
13:41
Another fix to the hash signature algorithm in vfslog.c. (check-in: 34212aa8c4 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: eaf4de13a6 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: 24a827b876 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: d27b88b8c2 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: e97d7d3044 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: f7cc30d45b user: drh tags: row-size-est)
22:25
Fix test cases for the new information in PRAGMA index_list. (check-in: dd03be1065 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: 65553ff34b 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: 3fd5e33217 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: 18bd6ba96d user: drh tags: row-size-est)
2013-10-07
21:49
Fix compilation issue with MSVC. (check-in: 36d64dc36f 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: cb34cfe57c user: drh tags: row-size-est)
16:53
Try to remember statistics from ANALYZE using LogEst instead of u64. (Leaf check-in: 8e78557a40 user: drh tags: log-stats)
10:48
Merge bug fixes from trunk. (check-in: 1d7b2dc0ea 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: 0aca31e151 user: drh tags: trunk)
2013-10-06
22:52
Remove an incorrect debugging assert() that was accidently added during the STAT4 enhancement. (check-in: 2bb7f74bbd user: drh tags: trunk)
22:12
Accept the sz=N parameter on table-only lines of sqlite_stat1. (check-in: e9e932aa40 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: 029430c503 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: 8b4aa0c7a2 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: 5252aeb619 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: 66c4a251d6 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: de78250ad2 user: drh tags: index-scan-rate)
2013-10-04
20:39
Merge trunk changes. (check-in: c6ac80ed8d user: drh tags: index-scan-rate)
18:29
Further refinements of the index scanning speed logic. (check-in: e5d9371da9 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: 087af29ee2 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: 2f394de88f 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: 07462bb605 user: drh tags: index-scan-rate)
02:36
Progress toward using the iScanRatio information on indices. Many tests are still failing. (check-in: 6c352edbba 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: 9f2f4c0a50 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: baf8ce5916 user: dan tags: trunk)
20:28
Merge latest trunk changes. (Closed-Leaf check-in: 24aa20da22 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: f6819c5f33 user: dan tags: fts4-docid-range-constraints)
19:21
Experimental branch allowing different postulated scan rates for each index. (check-in: d59d97b0a8 user: drh tags: index-scan-rate)
15:39
The sqlite3FixInit() routine cannot fail. So change the return type from "int" to "void". (check-in: 500c5932fe 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: 8338232a11 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: f35f6ae3da user: dan tags: trunk)
11:27
Remove unnecessary memset() calls from test code. (check-in: eec3187bc6 user: drh tags: trunk)
