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: 2f89e9e6 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: 46d8f5e3 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: 657c9fb5 user: drh tags: trunk
02:47
More optimizations. (CVS 816) check-in: a362981b user: drh tags: trunk

More optimizations. (CVS 813) check-in: 5809132f user: drh tags: trunk
2003-01-04
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: 6c304024 user: drh tags: trunk
18:53
Another optimization to the btree logic. (CVS 811) check-in: 03d20673 user: drh tags: trunk

2003-01-03
02:04
Allow the rollback journal to be empty except for its header. Ticket #212. (CVS 809) check-in: 1ba41bc2 user: drh tags: trunk
2003-01-02
14:43
Code optimizations to help the library run faster. (CVS 808) check-in: db745e87 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: a1c071ea user: drh tags: trunk
2002-12-28
01:26

14:13
Make sure the host machine has enough disk space before running the large file tests. (CVS 800) check-in: b1ec5478 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: f04547ed user: drh tags: trunk
2002-12-07
21:45
Save the full pathname of the database file so that journalling still works even if the user changes working directories after opening the databae. Ticket #200. (CVS 798) check-in: 1c58b4fc user: drh tags: trunk
2002-12-04
22:29

21:50

2002-12-03
02:34
Allow an aggregate function in the HAVING clause even if no aggregates appear in the result set. Ticket #187. (CVS 793) check-in: 33c6fd6b 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: 83b2c27a user: drh tags: trunk
2002-11-20
11:55

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: 745d6639 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: 263a8ca4 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: a6ef6657 user: drh tags: trunk
2002-11-09
00:33

Bump the version number to 2.7.2. (CVS 755) check-in: a164528e user: drh tags: trunk
19:04
Bug fix: When multiple SQL statements were passed into a single sqlite_exec() call, execution speed would decrease for each statement executed because VDBE cursors were not being reused. Now the cursors are reused and execution time is linear. (CVS 754) check-in: b0d27a37 user: drh tags: trunk
2002-09-21
15:57

23:20
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. (CVS 739) check-in: 8c2a0836 user: drh tags: trunk
2002-08-31

2002-08-29
23:59
If the database is locked when sqlite_open() is called, sqlite_exec() should still honor the busy callback and should return an error message together with the SQLITE_BUSY result code. (CVS 733) check-in: 78a0229a user: drh tags: trunk
2002-08-28
03:00

Turn of the reporting of datatypes in the 4th callback argument unless the SHOW_DATATYPES pragma is ON. Eliminate the NULL pointer that used to separate the beginning of datatypes from the end of column names so that the callback can test to see whether or not datatypes are provided.

Partial fix for a problem with LEFT OUTER JOIN. It used to be that the test for the right-hand table not matching the left table occurred after all ON, USING, WHERE clause processing. The test should occur after ON and USING clauses are checked but before the WHERE clause is check. This fix works as long as the total number of "AND" separated terms in the ON, USING, and WHERE clause does not exceed 32. To do: make this work for any number of terms and add test cases. that (CVS 639) check-in: 8b6574cf user: drh tags: trunk
