| 14:46 | Avoid calling truncate() and stat() on the checkpoint journal to improve the speed of a large number of UPDATEs within a transaction. (CVS 819) (check-in: 2f89e9e696 user: drh tags: trunk) | |
| 13:55 | In the VDBE, allocate space to hold column names when the VDBE first starts. The ColumnCount opcode now just writes the null terminator into this space. (CVS 818) (check-in: 46d8f5e377 user: drh tags: trunk) | |
| 13:43 | When constructing records and index keys, use static string space rather than mallocing (when possible) for a small speed improvement. (CVS 817) (check-in: 657c9fb513 user: drh tags: trunk) | |
| 02:47 | More optimizations. (CVS 816) (check-in: a362981b20 user: drh tags: trunk) | |

| 19:44 | Parameterize the number of adjacent pages that participate in the balancing algorithm in the BTree. But leave the setting at the current value of 3. (CVS 812) (check-in: 6c304024bb user: drh tags: trunk) | |

| 14:43 | Code optimizations to help the library run faster. (CVS 808) (check-in: db745e87dc user: drh tags: trunk) | |
|
2003-01-01
| ||
| 23:06 | If compiled with the -DVDBE_PROFILE=1 option, special code is inserted that uses the pentium RDTSC instruction to compute very precise runtimes on all VDBE opcodes. (This only works on i586 processors, of course.) The results are written into the vdbe_profile.out file for analysis. Hopefully, this new feature will reveal hot spots that can be optimized to make the VDBE run faster. (CVS 807) (check-in: a1c071ea18 user: drh tags: trunk) | |

2002-12-28

| 14:13 | Make sure the host machine has enough disk space before running the large file tests. (CVS 800) (check-in: b1ec547865 user: drh tags: trunk) | |
| 13:05 | Take care not to modify the sqlite* pointer to sqlite_exec() if we suspect that the pointer is stale - that it has previously been passed to sqlite_close(). Possible fix for ticket #202. Prior to this fix, test misuse-5.3 was causing a change to a buffer that had been previously free()-ed. (CVS 799) (check-in: f04547edfa user: drh tags: trunk) | |
|
2002-12-07
| ||

|
2002-12-04

| 21:50 | Fixes to the logic that decides if the ORDER BY can be ignored due to the use of an index. Tests updated. (CVS 796) (check-in: bfb9a2aa93 user: drh tags: trunk) | |
| 20:01 | Scan the table backwards if there is an ORDER BY ... DESC clause that can be satisfied by an index. (CVS 795) (check-in: c7a3487981 user: drh tags: trunk) | |
| 13:40 | Add the sqliteBtreePrevious() routine to the BTree module API. This is in anticipation of implementing reverse order searching of a table. (CVS 794) (check-in: 0ad1d93879 user: drh tags: trunk) | |
|
2002-12-03
| ||

2002-12-02
| ||

|
2002-12-01
| ||
| 02:00 | Fixed large file support under Linux. I'm unable to test under Windows. Ticket #191. (CVS 790) (check-in: 9864a1265b user: drh tags: trunk) | |
|
2002-11-24
| ||
| 14:52 | Add the "space_used.tcl" script to the tools directory. This script is used to measure how much disk space is used by each table and index of a database. (CVS 789) (check-in: 83b2c27a56 user: drh tags: trunk) | |
|
2002-11-20
| ||

| 01:04 | Back out the changes in the pager that sorted pages prior to writing them to the database. Additional measurements showed no performance gains. (CVS 785) (check-in: 745d66395d user: drh tags: trunk) | |
| 00:05 | Replace the atoi() library routine with a faster home-grown version in the VDBE. This gives a dramatic speed improvement for some kinds of queries. (CVS 784) (check-in: 263a8ca40f user: drh tags: trunk) | |
|
2002-11-10
| ||
| 23:32 | Two optimizations to the pager: (1) Write dirty pages back to the database file in order and (2) Keep a separate list of in-memory pages that are in the checkpoint journal in order to speed a checkpoint commit. (CVS 783) (check-in: a6ef6657a4 user: drh tags: trunk) | |
|
2002-11-09
| ||
| 00:33 | Try to better detect when the library is compiled for large file support (LFS) but the support is not available in the host OS kernel. (CVS 782) (check-in: a29d60ecc5 user: drh tags: trunk) | |
|
2002-11-06
| ||
| 14:08 | Add large file support to Windows. Change large file support for Unix so that it compiles automatically - without requiring special options on the compiler command line. (CVS 781) (check-in: 2008b56fe1 user: drh tags: trunk) | |

| 12:04 | Rename all tests so that the first part of the test name corresponds to the file that contains that test. This makes it much easier to find a particular test after it fail. (CVS 749) (check-in: 6cb80ae10a user: drh tags: trunk) | |

Relax the locking requirements on BTree cursors. Any number of read and
write cursors can be open at the same time now, but a write cannot occur
as long as one or more read cursors are open.
Before this change, one or more read cursors could be open on a table, or a single write cursor, but not both. Both policies have the same desirable effect: they prevent writes to a table while a sequential scan of that table is underway. But the new policy is a little less restrictive. Both policies prevent an UPDATE from occurring inside a SELECT (which is what we want) but the new policy allows a SELECT to occur inside an UPDATE.
