20:45
Performance optimizations in the pager_write() routine of pager.c. check-in: bc5febef user: drh tags: trunk
19:48
Reduce the number of calls to the subjRequiresPage() routine inside of pager. check-in: e50ff39a user: drh tags: trunk
19:35
Create and use a new pager interface sqlite3PagerUnrefNotNull() that works just like sqlite3PagerUnref() but guarantees that its argument is not a NULL pointer. check-in: e00f37e2 user: drh tags: trunk
18:50
Enhance the pcache1PinPage() routine so that it called much less often and runs much faster in the cases when it is actually called. check-in: a845779c user: drh tags: trunk
16:42
Avoid unnecessary calls to sqlite3_free() from within sqlite3VXPrintf(). check-in: e2a8b280 user: drh tags: trunk
16:23
Simplication and optimization of error message handling. check-in: 9d347f54 user: drh tags: trunk
2013-12-11
15:47
Add the SQLITE_FCNTL_SYNC and SQLITE_FCNTL_COMMIT_PHASETWO file-controls and have the pager call them at appropriate times. This is needed in order to enable ZIPVFS to do multi-file atomic commits. check-in: 552f94d5 user: drh tags: trunk
14:17
Merge in the latest trunk changes. Closed-Leaf check-in: 9ff4dfe1 user: drh tags: zipvfs-multifile-commit
14:00
Fix a bug in the shell ".import" command: Do not end the field when an escaped double-quote occurs at the end of a CRNL line. check-in: 5e239ecd user: drh tags: trunk
12:02
Remove an unreachable conditional inserted by the previous check-in. check-in: 3e1d55f0 user: drh tags: trunk
11:03
Have the crash-test infrastructure code in test6.c read and write the 512-byte block containing the pending-byte lock as normal. Earlier versions did not access this part of the file in order to avoid triggering an assert in os_unix.c. But the assert() has since been removed. And not reading/writing this part of the file causes problems for multiplexor tests. check-in: fdc3f3fa user: dan tags: zipvfs-multifile-commit
11:00
Fix harmless compiler warnings. check-in: a7e5fcd6 user: drh tags: trunk
02:21
Fix harmless compiler warning. check-in: 2525296d user: mistachkin tags: trunk
00:59
Do not run the tool/vdbe-compress.tcl script that generates the vdbeExecUnion object that reduces the size of the sqlite3VdbeExec() stack frame unless the SQLITE_SMALL_STACK compile-time option is specified as on of the OPTS in the makefile. The vdbeExecUnion object gets in the way of C-compiler optimizer and results in slightly slower code. check-in: 4d078147 user: drh tags: trunk
2013-12-10
21:38
Avoid unnecessary calls to sqlite3VdbeSerialType() from within sqlite3VdbeSerialPut(). check-in: 079c04a5 user: drh tags: trunk
20:53
In the OP_MakeRecord opcode, factor out affinity changes into separate loop, for a slight performance advantage. check-in: 1c6ee9b8 user: drh tags: trunk
19:49
Simplify and improve the performance of the sqlite3VdbeMemGrow() routine. check-in: 48ecf187 user: drh tags: trunk
17:34
Use SQLITE_FCNTL_SYNC instead of SQLITE_FCNTL_SYNC_OMITTED. Add documentation in for FCNTL_SYNC and FCNTL_COMMIT_PHASETWO. check-in: 46231af9 user: dan tags: zipvfs-multifile-commit
16:35
Merge changes from the trunk. check-in: 3ee736a3 user: dan tags: zipvfs-multifile-commit
16:27
Fix handling of errors returned by the SQLITE_FCNTL_OMIT_SYNCED file-control. check-in: d9a5f44f user: dan tags: zipvfs-multifile-commit
2013-12-09
23:17
Simplifications to the OP_MakeRecord opcode and the sqlite3VdbeSerialPut() helper function. check-in: 7277a769 user: drh tags: trunk
21:48
Correct the VFS name as reported by the file control when explicitly using the 'win32-longpath' VFS. check-in: c43b59da user: mistachkin tags: trunk
21:06
Reduce the number of times that OP_Column calls sqlite3VdbeMemMakeWriteable(). check-in: 6b518635 user: drh tags: trunk
20:43
Simplify the sqlite3BtreeKeyFetch() and sqlite3BtreeDataFetch() interfaces to the storage engine. check-in: bf975985 user: drh tags: trunk
20:42
Modify the way some internal file-controls are invoked. In order to support multi-file transactions in the zipvfs extension. check-in: 32fb1784 user: dan tags: zipvfs-multifile-commit
19:25
Minor performance optimizations in pager.c. check-in: ba9eef5f user: drh tags: trunk
19:03
Performance optimizations for sqlite3VXPrintf(). check-in: 9227ad48 user: drh tags: trunk
12:24
Fix an incorrect test number in the output of the speedtest1.c program. No changes to the test algorithms. check-in: fbfc075a user: drh tags: trunk
03:07
Avoid unnecessary (no-op) calls to sqlite3DbFree() from sqlite3VdbeMemRelease(). check-in: 2d6dd7c2 user: drh tags: trunk
02:32
Use memmove() rather than a home-made copy loop in insertCell() too. check-in: a3d796b1 user: drh tags: trunk
01:58
Use memmove() rather than a home-made copy loop in dropCell() of btree.c, for a size reduction and performance improvement. check-in: 78e17068 user: drh tags: trunk
01:04
Avoid unnecessary no-op calls from getAndInitPage() to btreeInitPage() in the btree.c logic. check-in: 81f5ae13 user: drh tags: trunk
00:47
Use putVarint32() instead of putVarint() for a quantity that can never exceed 2GiB - 1. check-in: 6996fb34 user: drh tags: trunk
2013-12-08
23:33
Another simplification to the OP_MakeRecord opcode, making it slightly faster and very slightly smaller. check-in: f2f5a3ce user: drh tags: trunk
22:59
Avoid unnecessary calls to sqlite3VarintLen() from the OP_MakeRecord opcode. check-in: 7a234fc3 user: drh tags: trunk
19:54
Interchange two conditions in an "if" statment in sqlite3PagerAcquire() for very slight (0.06%) overall performance increase. check-in: fbcc1a3e user: drh tags: trunk
2013-12-07
23:35
Do not allow cursor hints to use expressions containing subqueries. This change fixes the problem seen in the previous check-in. check-in: bfefc575 user: drh tags: cursor-hints
20:39
If the SQLITE_ENABLE_CURSOR_HINTS macro is defined, then invoke the sqlite3BtreeCursorHint() interface to provide hints to the storage engine about rows that need not be returned. Hints can be disabled using SQLITE_TESTCTRL_OPTIMIZATIONS with SQLITE_CursorHints (0x2000). Cursor hints are not used by the built-in storage engine of SQLite but might be useful to applications that provide their own storage engine. The current code is work-in-progrss and contains bugs. check-in: 3a9bec52 user: drh tags: cursor-hints
17:01
Increase the version number to 3.8.3. check-in: 23d00f22 user: drh tags: trunk
16:56
At the start of each journaled write transaction, check to see if the database file has been moved, and if it has refuse to start the transaction, returning an SQLITE_READONLY_DBMOVED error code. Writing to a moved or renamed database is still allowed when journal_mode is OFF or MEMORY. check-in: 369a23e0 user: drh tags: trunk
16:45
Back out the new device capability. The determination of whether or not a file has moved is now done strictly using a file-control. Closed-Leaf check-in: 9c59f5af user: drh tags: detect-moved-db
12:29
Actually look at i-node numbers to determine whether or not the database file has moved. check-in: 2b1884dc user: drh tags: detect-moved-db
2013-12-06
23:25
Performance optimization to the moveToRoot() subroutine in btree.c. check-in: b5842a70 user: drh tags: trunk
22:45
Use memcmp() instead of the BINARY collating function where possible, for a performance boost. check-in: c5a3a1af user: drh tags: trunk
22:44
Remove some commented-out code from sqlite3BtreeMovetoUnpacked() to try to make it more readable. check-in: 2d62d113 user: drh tags: trunk
19:58
Add the SQLITE_READONLY_DBMOVED error code to the sqlite3ErrName() function. check-in: 7789f801 user: mistachkin tags: detect-moved-db
17:23
Only error out on a database file move when attempting to start a write transaction. Assume read transactions are still safe. And make the error SQLITE_READONLY_DBMOVED instead of SQLITE_IOERR_NODB. check-in: 28348f2a user: drh tags: detect-moved-db
15:49
Update to the 3.8.2 release. check-in: e579661a user: drh tags: sessions
15:37
Add code to detect if the database file is moved or deleted out from under SQLite and return an SQLITE_IOERR_NODB. check-in: 8759a8e4 user: drh tags: detect-moved-db
14:53
Version 3.8.2 check-in: 27392118 user: dan tags: trunk, release, version-3.8.2

17:12
Fix harmless compiler warnings and improve the MSVC makefile. check-in: c6325670 user: drh tags: trunk
16:41
Fix two potential (and apparently harmless) shift overflows discovered by the -fcatch-undefined-behavior option of clang. check-in: e19eead8 user: drh tags: trunk
2013-12-03
23:33
Make use of the CC nmake macro even when cross-compiling (with MSVC). Closed-Leaf check-in: aae7b30e user: mistachkin tags: memTests
22:33
Fix harmless compiler warnings. check-in: a12d214e user: mistachkin tags: memTests
22:32

20:51
Merge in trunk changes. check-in: a2914d6b user: drh tags: sessions
19:49
Remove a branch in STAT4 logic that is no longer reachable after the previous change. check-in: eca7d3f1 user: drh tags: trunk
19:16
Fix a possible (and probably harmless) uninitialized variable in STAT3/4. check-in: 33ad4f91 user: drh tags: trunk
18:26
Fix an alignment problem in the stat3/stat4 code affecting 32-bit platforms. check-in: 14f9bc79 user: dan tags: trunk
17:09
Fix a typo in fts3varint.test preventing the valgrind permutation test from running. check-in: b654a4ec user: dan tags: trunk
10:35
Modify test file conflict2.test so that it works with the "inmemory_journal" permutation. check-in: e4164fd8 user: dan tags: trunk
10:14
Remove an unnecessary branch from the UPDATE logic - one that was also unreachable except following an OOM on x64. check-in: 72f97277 user: drh tags: trunk
09:49
Add a "database_may_be_corrupt" directive to test file fuzz3.test. Reformat an assert() statement in vdbeaux.c to make its intent clearer. check-in: 9d8a0e13 user: dan tags: trunk
02:52
Change some unreachable test conditions to NEVER(). check-in: 7d99858b user: drh tags: trunk

Detect a corrupt UnpackedRecord and return SQLITE_CORRUPT prior to calling sqlite3BtreeMovetoUnpacked(). check-in: 55ec474d user: drh tags: trunk
2013-11-29
15:39
Change the name of the CORRUPTIBLE macro to CORRUPT_DB. check-in: f865be10 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: 15e4f63d user: drh tags: trunk
2013-11-28
19:28
Update a few test cases to account for the new error message formats. check-in: 65a5bce3 user: dan tags: trunk

Update documentation of sqlite3_column() for clarity. Update evidence marks on test cases. check-in: ec2d47a1 user: drh tags: trunk
18:00
Fix spelling typo in speedtest1.exe. check-in: ae90300e user: mistachkin tags: trunk
14:50
Fix some harmless compiler warnings in speedtest1.exe. check-in: c75f561f user: drh tags: trunk
13:48
Additional test cases for skip-scan. check-in: ce70803f user: drh tags: trunk
13:24
Make sure the colWidth array is correctly initialized in the ".explain" command of the shell. check-in: ceebcdca 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: 83c0bb99 user: drh tags: trunk
04:00
Avoid using the GetVersionEx functions if they are considered deprecated. check-in: afdca299 user: mistachkin tags: trunk
03:01
Avoid using the GetVersionEx functions if they are considered deprecated. Closed-Leaf check-in: 0ea9e472 user: mistachkin tags: vs2013
01:23
Add additional test cases for skip-scan. check-in: 1ae4915d user: drh tags: trunk
00:45
Add additional test cases and requirements evidence marks for WITHOUT ROWID. check-in: b408d788 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: 0978bac6 user: drh tags: trunk
22:46
Add requirements test cases for determining when an expression is true and when it is false. check-in: 838654e5 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: d84aa44e user: drh tags: trunk
18:22
Reduce the amount of code used to implement OP_SeekGe and similar. check-in: 8b12a15a user: dan tags: trunk
18:00
Merge in performance enhancements from trunk. check-in: fc9ae839 user: drh tags: sessions
16:51
Fix a possible NULL pointer deference in the wordcount test program. check-in: 6f91dca0 user: drh tags: trunk
16:48
Change tclsqlite3.c so that it never invokes ctype macros with signed character arguments. check-in: c07caabf 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: fafca560 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: 6f53fc71 user: drh tags: trunk
01:13
Fix comment. check-in: 8364af39 user: mistachkin tags: winHdr
