The callback-free API is now working, though much more testing is need. (CVS 853) check-in: 162b2591 user: drh tags: trunk
2003-01-28
23:13
First code for the new callback-free API. All regression tests pass but the new API is mostly untested and is unlikely to work. (CVS 852) check-in: 065fa818 user: drh tags: trunk
2003-01-26
15:28
Added section on comments. Corrected broken end tags. (CVS 851) check-in: c957f4f0 user: jplyon tags: trunk

16:32
Version 2.7.6 (CVS 850) check-in: bdba796f user: drh tags: trunk
15:43
Fix a bug in the rollback validation logic (code that only runs during debugging). The problem was introduced by check-in (835). (CVS 849) check-in: b6ea0da7 user: drh tags: trunk
14:34
Remove an unused variable. (CVS 848) check-in: 18f4ffaa user: drh tags: trunk

02:39
In the pager, cache a pointer to the first page on the freelist that does not need to be synced. This makes a fetch of a page that is not in cache go a lot faster when the cache is full. This check-in also adds some performance instrumentation to the OS layer. (CVS 842) check-in: 00f08fc0 user: drh tags: trunk

17:05
Do not report an error if the input to the sqlite shell ends in a comment. Ticket #211. (CVS 838) check-in: 32a8e6e9 user: drh tags: trunk
17:04
Check the validity of the database connection before the trace callback, not afterwards. (CVS 837) check-in: 960a2e4a user: drh tags: trunk
2003-01-16
16:28
Add the sqlite_trace() hook for tracing the SQL that an application executes. The plan is to leave this API undocumented for the time being, in case we want to make changes to it later. (CVS 836) check-in: f67bff8f user: drh tags: trunk
13:42
Improvements to the pager to help large updates against a large database run faster. Also improved the testing of the pager rollback algorithms. (CVS 835) check-in: 717523d3 user: drh tags: trunk
2003-01-14
13:48

18:07
Forgot to include the new "auth.c" source file in the previous checkin. (CVS 828) check-in: 76019164 user: drh tags: trunk
18:02
Initial check-in of the code for the new sqlite_set_authorizer() API function. The code is mostly untested at this point. (CVS 827) check-in: 52d5007f user: drh tags: trunk

2003-01-08
13:02
Port ot MacOS Classic. Ticket #218. (CVS 820) check-in: 13f82d67 user: drh tags: trunk
2003-01-07
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: 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

2003-01-05
21:41
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

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

2002-12-17
22:50
Version 2.7.4 (CVS 803) check-in: 0224db6f user: drh tags: trunk
14:30
Preparing for the 2.7.4 release. (CVS 802) check-in: f685ae15 user: drh tags: trunk
14:19

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
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: bfb9a2aa 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: c7a34879 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: 0ad1d938 user: drh tags: trunk
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

2002-11-10
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
