2013-12-02
21:25
Another #if SQLITE_VERSION_NUMBER macro in speedtest1.c for compatibility with older versions of SQLite. (check-in: bc8eacc7f7 user: drh tags: trunk)
01:24
Still more #if SQLITE_VERSION_NUMBER macros in test/speedtest1.c to enable compilation against older versions of SQLite. (check-in: 4b20cf4206 user: drh tags: trunk)
2013-12-01
18:10
Add some #if SQLITE_VERSION_NUMBER macros to test/speedtest1.c in order to make it compatible with older versions of SQLite so that it can be used for historical speed comparisons. (check-in: a9e1627ae7 user: drh tags: trunk)
01:18
Fix typos in the header comment on the sqlite3Atoi64() routine. (check-in: c85e0c546e user: drh tags: trunk)
2013-11-30

Detect a corrupt UnpackedRecord and return SQLITE_CORRUPT prior to calling sqlite3BtreeMovetoUnpacked(). (check-in: 55ec474db8 user: drh tags: trunk)
2013-11-29
15:39
Change the name of the CORRUPTIBLE macro to CORRUPT_DB. (check-in: f865be10e8 user: drh tags: trunk)
15:06
Add a new sqlite3_test_control() that indicates that database files are always well-formed. Use this during testing to enable assert() statements that prove conditions that are always true for well-formed databases. (check-in: 15e4f63d1f user: drh tags: trunk)
2013-11-28
19:28
Update a few test cases to account for the new error message formats. (check-in: 65a5bce3ff user: dan tags: trunk)
14:14
Remove an assert() condition that may not be true if the database file is corrupt. Update a test case in corruptC.test. (check-in: 0bcf75516f user: dan tags: trunk)
06:17
Fix a test case in temptrigger.test so that it works in auto-vacuum mode. (check-in: c3b7a0e61f user: dan tags: trunk)
2013-11-27
21:07
Remove unnecessary local variables from sqlite3VdbeExec() in order to reduce stack-space requirements of that routine. (check-in: 81891288d9 user: drh tags: trunk)
19:17
Update documentation of sqlite3_column() for clarity. Update evidence marks on test cases. (check-in: ec2d47a1db user: drh tags: trunk)
18:00
Fix spelling typo in speedtest1.exe. (check-in: ae90300e8e user: mistachkin tags: trunk)
14:50
Fix some harmless compiler warnings in speedtest1.exe. (check-in: c75f561f33 user: drh tags: trunk)
13:48
Additional test cases for skip-scan. (check-in: ce70803f5e user: drh tags: trunk)
13:24
Make sure the colWidth array is correctly initialized in the ".explain" command of the shell. (check-in: ceebcdcaf1 user: drh tags: trunk)
04:22
Lower the threshold for using skip-scan from 50 to 18, based on experiments that show that 18 is the approximate break-even point for a variety of schemas. (check-in: 83c0bb9913 user: drh tags: trunk)
04:00
Avoid using the GetVersionEx functions if they are considered deprecated. (check-in: afdca29966 user: mistachkin tags: trunk)
03:01
Avoid using the GetVersionEx functions if they are considered deprecated. (Closed-Leaf check-in: 0ea9e4722b user: mistachkin tags: vs2013)
01:23
Add additional test cases for skip-scan. (check-in: 1ae4915d4d user: drh tags: trunk)
00:45
Add additional test cases and requirements evidence marks for WITHOUT ROWID. (check-in: b408d78810 user: drh tags: trunk)
2013-11-26
23:27
Make sure the update hook is not invoked for WITHOUT ROWID tables, as the documentation specifies. This bug was found while adding requirements marks, so a few extraneous requirements marks are included in this check-in. (check-in: 0978bac6b8 user: drh tags: trunk)
22:46
Add requirements test cases for determining when an expression is true and when it is false. (check-in: 838654e563 user: drh tags: trunk)
21:18
Changing the CAST behavior of REAL values actually changed a documented requirement. So we also have to change the requirement evidence text to match. (check-in: d84aa44e39 user: drh tags: trunk)
18:22
Reduce the amount of code used to implement OP_SeekGe and similar. (check-in: 8b12a15a2a user: dan tags: trunk)
16:51
Fix a possible NULL pointer deference in the wordcount test program. (check-in: 6f91dca0de user: drh tags: trunk)
16:48
Change tclsqlite3.c so that it never invokes ctype macros with signed character arguments. (check-in: c07caabf23 user: drh tags: trunk)
16:20
Do not try to run the atof1.test test script on ARM hardware which lacks the "long double" type. (check-in: fafca560f2 user: drh tags: trunk)
15:45
Change the REAL-to-INTEGER casting behavior so that if the REAL value is greater than 9223372036854775807.0 then it is cast to the latest possible integer, 9223372036854775807. This is sensible and the way most platforms work in hardware. The former behavior was that oversize REALs would be cast to the smallest possible integer, -9223372036854775808, which is the way Intel hardware works. (check-in: 6f53fc7106 user: drh tags: trunk)
00:28
Better support for UTF-8 paths on Cygwin. (check-in: 9954327c0f user: mistachkin tags: trunk)
2013-11-25
23:42
Add SQLITE_CONFIG_WIN32_HEAPSIZE option to configure the maximum isolated heap size on Windows. (check-in: 914e6c9d88 user: mistachkin tags: trunk)
22:24
Change a while-loop into a do-loop in sqlite3VdbeRecordCompare() and add an assert() to verify that the do-loop really is appropriate. This gives about a 10% performance boost in that routine, or a 0.9% boost overall. (check-in: 011a6be439 user: drh tags: trunk)
21:49
Clarify docs for the SQLITE_CONFIG_WIN32_HEAPSIZE option. (Closed-Leaf check-in: 51e876074a user: mistachkin tags: winHeapSize)
21:41
Remove a NEVER() from a branch that is now reachable during OOM faults. (check-in: 18bdcb05c2 user: drh tags: trunk)
20:50
Optimizations to the sqlite3BtreeMovetoUnpacked() routine in storage engine making it about 17.8% faster, which in turn makes SQLite over 1.2% faster overall. (check-in: 032e89934f user: drh tags: trunk)
20:14
Return an SQLITE_CORRUPT error if the content size field of a table record extends off the end of a page. (Closed-Leaf check-in: b48c4e4021 user: drh tags: btree-optimization)
17:38
Uses shifts rather than division for arithmetic on the cell indices, since those indices are always non-negative. (check-in: 5bf2a3feeb user: drh tags: btree-optimization)
16:52
Optimize the skipping of the payload size field when doing a binary search for a rowid. (check-in: 55e5bfa231 user: drh tags: btree-optimization)
16:23
Arrange for sqlite3BtreeMovetoUnpacked() to always leave the cursor cell parse cache invalidated. This fixes issues with previous check-ins on this branch and also runs faster. (check-in: a74675607f user: drh tags: btree-optimization)
15:01
More optimizations to sqlite3BtreeMovetoUnpacked(). But there are failures in TH3. Committing this intermediate state to facilitate bisecting. (check-in: f80497be44 user: drh tags: btree-optimization)
14:10
More improvements to sqlite3BtreeMovetoUnpacked() performance. (check-in: 8868069823 user: drh tags: btree-optimization)
02:38
Performance improvements in sqlite3BtreeMovetoUnpacked(). (check-in: d0fb7acea7 user: drh tags: btree-optimization)
2013-11-24
23:18
Better support for UTF-8 paths on Cygwin. (Closed-Leaf check-in: 484162b6e5 user: mistachkin tags: cygUtf8)
01:14
Add the --scratch parameter to speedtest1. Improved error messages when misconfiguring memory parameters in speedtest1. (check-in: 8f3c767a30 user: drh tags: trunk)
00:46
The MEMSYS5 algorithm does not have to return the block with the lowest address. Any block of the appropriate size will do. Use the first block found on the freelist for the appropriate size for a performance improvement. (check-in: 12e612e8e7 user: drh tags: trunk)
2013-11-23
22:45
A much simpler fix is to simply change MEMSYS5 so that it takes any free block of the appropriate size (the first on the list of free blocks) rather than searching for the one with the smallest address. This is also faster than using the min-heap algorithm. Need to research to verify that the allocator still satisfies the Robson proof, however. (Closed-Leaf check-in: 8191b51212 user: drh tags: memsys5-performance)
21:29
Add newlines at the end of some error messages in speedtest1. (check-in: 6b98f0af7a user: drh tags: trunk)
11:45
Report errors from sqlite3_exec() and sqlite3_config() in speedtest1. Fix a bug in the main testing logic that was found by these error reports. (check-in: 659f1a98ae user: drh tags: trunk)
04:32
Fix the order of parameters to SQLITE_CONFIG_PAGECACHE in the speedtest1.exe program. (check-in: dbe85ef6d2 user: drh tags: trunk)
