Fix compilation issue for WinRT. check-in: 7a2006ca user: mistachkin tags: trunk
2013-10-10
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
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: af7abebe 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
19:21
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
