Add the SQLITE_ENABLE_API_ARMOR compile-time option. This is a work in progress and is not yet completely functional. check-in: c297a84b user: drh tags: api-armor
2014-10-23
01:01
Implement sqlite3_create_collation() by invoking sqlite3_create_collation_v2() with a NULL destructor argument. This saves a little space. check-in: 9762ad06 user: drh tags: trunk

Disable the use of strchrnul() unless specifically enabled by compile-time options. check-in: e580470d user: drh tags: trunk
19:57
Change the 0x800 bit of SQLITE_TESTCTRL_OPTIMIZATIONS so that it disables the loading of STAT3 and STAT4 content, not just the using of that content. Change the internal name of that bit to SQLITE_Stat34. check-in: ca3b00c4 user: drh tags: trunk
18:42
Merge latest trunk with this branch. check-in: 854a54c6 user: dan tags: defrag-opt

Call fsync() right after ftruncate() when in journal_mode=TRUNCATE and when synchronous=FULL in order to ensure that transactions are durable across a power loss that happens moments after the commit. Proposed fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1072773. check-in: 3e922208 user: drh tags: trunk
18:16
Further tuning of the cost estimates for skip-scan loops, especially for cases when skip-scan loops are in competition with regular loops. check-in: a27861c2 user: drh tags: trunk
16:01
Add WHERETRACE debugging output to the whereLoopAdjustCost() routine. check-in: ec1e942f user: drh tags: trunk
01:05
If a skip-scan is a proper subset of some other scan, then adjust the cost of the skip-scan upward so that it is more costly than the other scan. Such a cost imbalance can arise under STAT4 because of difficulties in getting an accurate estimate for skip-scans. check-in: f4b22a26 user: drh tags: trunk

Work around MSVC not being able to deduce that a local variable was initialized in a called function. check-in: 06c576c1 user: mistachkin tags: trunk
18:34
Changes to work around Win32 and MSVCRT APIs that are not present on Windows CE 200x. check-in: 1418c006 user: mistachkin tags: trunk
11:45
Update the vdbe-compress.tcl script to account for expressions of the form (123>var), where "var" should be replaced with a reference to a union member. check-in: 640345d8 user: dan tags: trunk
2014-10-15
15:28
Update releasetest.tcl so that x86-64 runs a superset of the x86 tests. check-in: 3c1e70f4 user: dan tags: trunk
14:45
Fix a problem causing lock5.test to fail in mmap-mode. check-in: b3e7b446 user: dan tags: trunk
11:55

11:31
Rearrange an expression in vdbemem.c to avoid a (harmless) reference to a possibly unitialized variable. check-in: 4a7b3fa0 user: dan tags: trunk
2014-10-14
20:25
Make sure new sqlite3_vtab objects created by the xCreate() virtual table method are initialized by the system, in accordance with the documentation. check-in: eab82330 user: drh tags: trunk

Fix some code duplication issues on this branch. Add minor optimizations to the new code. check-in: 58d7793b user: dan tags: defrag-opt
2014-10-13
23:39
Optimize a database corruption test inside of the OP_Column opcode. check-in: 005e5b38 user: drh tags: trunk
20:12
Use the padding word in the Mem object as temporary storage for serial_type value in OP_Record, and thus avoid a redundant computation of the serial_type for each column. check-in: 4b3b65ee user: drh tags: trunk
18:09
Merge trunk changes into this branch. check-in: d5b7c5a8 user: dan tags: defrag-opt
18:03
Further work on balance_nonroot(). check-in: 6594f9b4 user: dan tags: defrag-opt
17:42
Three small optimizations to vdbeaux.c. check-in: 04892f8b user: drh tags: trunk
16:02
Reduce the CPU load imposed by sqlit3VdbeCursorMoveto() by factoring out some of its functions and by avoiding unnecessary calls. check-in: c2799aec user: drh tags: trunk
13:00
Remove the OPFLAG_CLEARCACHE flag from OP_Column. In its place, change the P3 parameter of OP_SorterData to be the index of the pseudo-table cursor whose record header cache is to be cleared. This gives a small size reduction and performance increase. check-in: 20062f49 user: drh tags: trunk
2014-10-12
22:37
Remove the VdbeCursor.lastRowid cache of the current rowid, since maintaining the correct cache value uses more CPU cycles than just recomputing the rowid on the occasions when it is actually needed. Replace it with the VdbeCursor.aOffset field which used to be computed from VdbeCursor.aType when needed. Saves 100 bytes of code space and runs 0.2% faster. check-in: 91384a7d user: drh tags: trunk
2014-10-11
23:31
Performance optimization and very slight size reduction for OP_Column. check-in: 869c30e4 user: drh tags: trunk
20:00
Attempt to further reduce memcpy() in balance_nonroot(). check-in: fec849dc user: dan tags: defrag-opt
17:22
Simplification to the insertCell() routine in btree.c, resulting in a performance boost and a very small size decrease. It turns out that the extra work involved in sometimes avoiding an memcpy() of the first four bytes of a record takes more time than just unconditionally copying those four bytes. check-in: 66de1558 user: drh tags: trunk
10:52
Require the SQLITE_ENABLE_RTREE compile-time option in speedtest1.c in order to enable the R-Tree tests. check-in: 5d29a033 user: drh tags: trunk
02:12

19:15
Restrict the scope of the explainIndexRange() function in where.c. check-in: c3012452 user: drh tags: trunk
19:10
Fix a failing test case in index5.test. Also tweak the way cache memory is divided between read-only and dirty pages when using SQLITE_CONFIG_PAGECACHE to reduce IO in some cases. check-in: 8541dfb3 user: dan tags: trunk
18:09
Changes to enable compiling using VC6. check-in: 9ee5686a user: drh tags: trunk
17:47
When using the -config option to releasetest.tcl, default the testing type to "fulltest" if it is not specified on the command line. check-in: cf291cbe user: drh tags: trunk
17:44
Provide the new "-config CONFIG" option to the test/releasetest.tcl script, which allows one to run a single test configuration selected by name. check-in: d479e32b user: drh tags: trunk
17:20
Add the estimated number of output rows to the EXPLAIN QUERY PLAN output if compiled with SQLITE_EXPLAIN_ESTIMATED_ROWS. This feature is off by default for the time being. check-in: daa8314f user: drh tags: trunk
15:47
Simplify the code used to generate the text for EXPLAIN QUERY PLAN. check-in: beea1efc user: drh tags: trunk
15:01
Fix a potential problem in the whereRangeScanEst() routine when STAT4 is active. The problem was introduced by recent enhancements. check-in: 68e1b4de user: drh tags: trunk
13:08
Cause the command-line shell to return non-zero if the final SQL statement is incomplete. check-in: 177fff3b user: drh tags: trunk
2014-10-09
19:35
Change the balance_nonroot() routine to reduce the amount of memcpy work that takes place. This is a work in progress. check-in: 29304499 user: dan tags: defrag-opt
15:08
Allow FTS tokenizers to choose whether or not to consider the "*" character part of tokens or not. This restores the pre-[e21bf7a2ad] behaviour. Also fix a problem causing FTS to interpret tokens beginning with "*" characters as EOF. check-in: 49dfee7c user: dan tags: trunk
14:10
Add a test case for the memory leak fixed by the previous check-in. check-in: bae36d54 user: drh tags: trunk
14:00
Fix a memory leak associated with the FTS4 matchinfo() function. check-in: fb8da824 user: drh tags: trunk
2014-10-08

Remove an always-true branch in whereRangeScanEst(). Replace it with an assert(). check-in: 42e48fd3 user: drh tags: trunk
15:53
Fix up test cases to account for the new SQLITE_LIMIT_WORKER_THREADS limit. check-in: 6483d426 user: drh tags: trunk
14:28
Set the connection-specific lastRowid value before calling any SQL function. check-in: dff0f642 user: drh tags: trunk

More intuitive labels on ".wheretrace" output. check-in: adcb3fed user: drh tags: trunk
2014-10-07
23:02
Make sure the sqlite3VdbeMemClearAndResize() routine is never called with a zero size parameter, since a size of zero could lead to either a memory leak or an assertion fault. check-in: f672a380 user: drh tags: trunk
20:09
Fix the corruptI.test script so that it works with SQLITE_ENABLE_OVERSIZE_CELL_CHECK and with SQLITE_DEFAULT_AUTOVACUUM=1. check-in: e405b9e4 user: drh tags: trunk
16:59
Restrict the scope of the valueToText() routine. check-in: 13c962b3 user: drh tags: trunk
