21 check-ins using file www/changes.tcl version 85480df7

2002-12-17
14:19
If the "fake_big_file" command fails, be sure to close the file before returning. (CVS 801) check-in: fa1b5e21 user: drh tags: trunk
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
Fix a bug in the reverse scan logic that comes up when the table being scanned is empty. Add additional tests for the reverse scan. (CVS 797) check-in: 0051c87d user: drh tags: trunk
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
02:22
Honor ORDER BY clauses in VIEWs. Ticket #193. (CVS 792) check-in: dbf78932 user: drh tags: trunk
2002-12-02
04:25
Change to the pager to avoid opening journal files unnecessarily. This can sometimes results in a significant speed improvement. (CVS 791) check-in: fa5c0425 user: drh tags: trunk
2002-12-01
02:00
Fixed large file support under Linux. I'm unable to test under Windows. Ticket #191. (CVS 790) check-in: 9864a126 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
Automatically determine if pointers are 4 or 8 bytes in size during the compilation process. Ticket #190. (CVS 788) check-in: dd5396a7 user: drh tags: trunk
11:08
Get the new large file code working with the Borland compiler. Ticket #195. (CVS 787) check-in: da4a79e2 user: drh tags: trunk
2002-11-11
13:56
Remove extra from HTML output. Ticket #189. (CVS 786) check-in: dc5d9c12 user: drh tags: trunk
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
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: a29d60ec 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: 2008b56f user: drh tags: trunk
