63 check-ins using file test/tester.tcl version 2a7cce4a

2015-08-13
21:43
Convert the hint expression of the CursorHint opcode into a string for display by EXPLAIN. (Leaf check-in: 12640cb2 user: drh tags: cursor-hints-displayP4)
2014-07-15
11:59
Add simple tests for new sqlite3BtreeCursorHint() functionality. (check-in: 1efa6ed5 user: dan tags: cursor-hints)
2014-07-14
19:04
In the expression passed to sqlite3BtreeCursorHint() for the inner loops of joins, replace any TK_COLUMN references to columns in the outer loops with TK_REGISTER expressions (Expr.iTable indicates the specific register containing the value). There are no automated tests for this yet. (check-in: f9dddd00 user: dan tags: cursor-hints)
2014-01-28
00:49
Provide hints to the btree layer Next and Previous primitives to let them know if they can be no-ops if the underlying index is unique. (Leaf check-in: a2c347fa user: drh tags: branch-3.8.2)
2014-01-15
00:24
Merge recent fixes from trunk. Cherrypick of [c43b59dac1], [a221aa82bb], [e1eba1fb09], and [1e131094b5]. (check-in: c697d2f8 user: mistachkin tags: branch-3.8.2)
2013-12-23
15:35
Make sure the WhereLoop.aLTerm[] array is large enough when processing the skip-scan optimization. Fix for ticket [520070ec7fbaac]. (check-in: ac5852d6 user: drh tags: branch-3.8.2)
2013-12-11
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)
11:00
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)
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)
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)
15:37
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)
2013-12-05
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
Add memory subsystem related defines to the compile-time options list. (check-in: 52a44146 user: mistachkin tags: memTests)
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)
00:11
Fix a harmless compiler warning on MacOS. (check-in: 74328de1 user: drh tags: trunk)
2013-12-02
21:25
Another #if SQLITE_VERSION_NUMBER macro in speedtest1.c for compatibility with older versions of SQLite. (check-in: bc8eacc7 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: 4b20cf42 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: a9e1627a user: drh tags: trunk)
01:18
Fix typos in the header comment on the sqlite3Atoi64() routine. (check-in: c85e0c54 user: drh tags: trunk)
2013-11-30
12:49
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)
