Performance optimization in sqlite3VdbeCloseStatement(). (check-in: 1e96e5ec1e user: drh tags: trunk)
16:54
Performance optimization to sqlite3_blob_read(). (check-in: 7459f4b7ed user: drh tags: trunk)
16:27
Minor simplification and performance optimization for Direct Overflow Read. (check-in: 3e96d6efa8 user: drh tags: trunk)
02:26
Make SQLITE_DIRECT_OVERFLOW_READ work for in WAL mode as long as the page being read is not in the the -wal file. (check-in: 9879be1899 user: drh tags: trunk)
01:54
Enhancements to the kvtest utility program. Add the --jmode option. Improved output formatting. (check-in: 62a4851ccf user: drh tags: trunk)
00:58
Modify the ICU extension to use a static initializer, as VC++ complains about a dynamic initialization. Maybe the dynamic structure initialization is a GCC extension. This fixes a problem identified on the SQLite mailing list by Ziemowit Laski. (check-in: 50e60cb44f user: drh tags: trunk)
2017-01-25
20:55
Trim NULL values off the end of records when the SQLITE_ENABLE_NULL_TRIM compile-time option is used. Increase the size of the P5 operand to 16 bits. Fix a problem with short records in the sessions extension. (check-in: 4801bd59a0 user: drh tags: trunk)
18:53
Fix another pre-update hook issue, this time in sqlite3preupdate_old(). (Closed-Leaf check-in: c7651d21bf user: dan tags: trim-nulls)
18:12
Fix a test script problem in exclusive2.test causing it to fail on this branch. (check-in: f66614dc78 user: dan tags: trim-nulls)
17:44
Fix a problem with the pre-update hook on this branch. (check-in: 6fc4fbfa29 user: dan tags: trim-nulls)
14:58
Experimental enhancement to automatically trim NULL values from the end of records, for a reduced disk footprint. This change also involves increasing the P5 operand from 8 to 16 bits. (check-in: 118ded403b user: drh tags: trim-nulls)
14:38
Ensure that sqlite3_blob_reopen() correctly handles short rows. Fix for ticket [e6e962d6b0f06f46e]. (check-in: 8cd1a4451c user: drh tags: trunk)
13:54
Fix SQLITEINT_H macro usage in two extensions. (check-in: 0803390c15 user: drh tags: trunk)
04:41
Ensure that sqlite3_blob_reopen() correctly handles short rows. Proposed fix for ticket [e6e962d6b0f06f46e]. Further testing needed. (Closed-Leaf check-in: 57d8dad35c user: drh tags: blob_reopen-fix)
2017-01-23
19:11
Document the --mmap option in the --help screen for kvtest. Enhance kvtest so that numeric arguments can have suffixes like "K" or "M". Add kvtest to the unix makefiles. (check-in: 175bda8728 user: drh tags: trunk)
18:40
Add the --mmap option to the kvtest utility program. (check-in: 4948f7e6d2 user: drh tags: trunk)
16:56
Optimization: Try to avoid unnecessary btree searching when repositioning a cursor to the next row. (check-in: ee793d30c1 user: drh tags: trunk)
15:58
Add the missing SQLITE_API symbol to test_delete.c (it is not added automatically as this file is not part of the amalgamation). (check-in: 7a4f512ddf user: dan tags: trunk)
07:06
Fix a problem preventing FTS5 from correctly passing the FTS5_TOKENIZE_PREFIX flag to custom tokenizer implementations. (check-in: 03c601344e user: dan tags: trunk)
2017-01-22
16:34
Fix an uninitialized variable in the command-line shell. (check-in: 06b8001ade user: drh tags: trunk)
02:04
Fixes to documentation comments in the public header file. (check-in: 772dcb08f4 user: mistachkin tags: trunk)
00:11
Fix an initialized variable in kvtest. (check-in: ed62c5a656 user: drh tags: trunk)
2017-01-21
21:47
A better implementation of the moveto-neighbor optimization that checks for nearby rows on adjacent pages. (Closed-Leaf check-in: 2c4ecb85a4 user: drh tags: btree-moveto-neighbor)
16:54
B-tree optimization: When seeking on a rowid table that has already been positioned, check to see if the new row happens to be the next row on the same leaf page. That is a reasonably common case, and if it is true it avoids a full binary search. (check-in: 8e5cfb2039 user: drh tags: btree-moveto-neighbor)
16:27
Change sqlite3_blob_reopen() to call sqlite3VdbeExec() directly rather than going through sqlite3_step(). Performance enhancement. (check-in: 347df3c1fd user: drh tags: trunk)
15:55
In the kvtest.c test utility, reuse the buffer into which blobs are read, rather than reallocating it for each row. This is a closer match to how other test programs work, and thus provides a better comparison. (check-in: 0d1ad13a29 user: drh tags: trunk)
14:11
Remove an unnecessary sqlite3_bind_int64() call from sqlite3_blob_open(). Also other minor refactoring of the sqlite3_blob implementation. (check-in: 9d197a5323 user: drh tags: trunk)
2017-01-20
20:43
Minor performance optimization and size reduction to the accessPayload() routine in btree.c. (check-in: 264e5c10d7 user: drh tags: trunk)
16:47
Fix a typo in the help message for kvtest. (check-in: 8971d98f25 user: dan tags: trunk)
16:46
Add option "--stats" to test program kvtest. Specifying --stats causes kvtest to output information similar to the shell tool option of the same name. (check-in: 90291327fc user: dan tags: trunk)
16:09
Get the "--testset rtree" option working on speedtest1. Add the --rtree, --lookaside, and --clang options to the speed-check.sh script. (check-in: 87b640c8d0 user: drh tags: trunk)
00:40
Minor performance optimizations to sqlite3_blob_open() and sqlite3_blob_reopen(). (check-in: 52a61967d9 user: drh tags: trunk)
2017-01-19
21:20
If compiled with SQLITE_INLINE_MEMCPY, all memcpy() calls are replaced with in-line code. With that change, cachegrind shows which memcpy() calls are taking the most time. This is a performance-measurement hack only and is not for production use. (check-in: 9ed3852161 user: drh tags: trunk)
18:20
In the 'vtshim' extension, avoid accessing freed memory when handling errors from xCreate/xConnect. (check-in: ffd559afd3 user: mistachkin tags: trunk)
2017-01-18
22:47
In the 'windirent' test module, use a macro for the hidden/system attribute checking. (check-in: a84a08d071 user: mistachkin tags: trunk)
22:19
Remove superfluous option to Tcl 'lsort' in the vtabH test file. (check-in: b92cc6e58a user: mistachkin tags: trunk)
22:16
Make the vtabH-3.1 test more portable and robust. (check-in: d3c91c1fb3 user: mistachkin tags: trunk)
22:16
Fix handling of initial hidden and/or system files in the opendir() implementation for Windows. No changes to non-test code. (check-in: 26dd42b462 user: mistachkin tags: trunk)
2017-01-17
10:41
Fix a problem that could cause a spurious SQLITE_NOMEM error when attempting to resume an RBU operation if the previous client failed right after completing the incremental checkpoint. Also a "cannot vacuum wal db" error that could occur when resuming an RBU vacuum if an error (OOM or IO error) occurs during the incremental checkpoint. (check-in: 681d96eb82 user: dan tags: trunk)
00:10
Disable intrinsic functions for Windows using Clang, due to reports of linkage errors. This causes a 0.6% performance reduction. We will want to revisit this change in the future. (check-in: 7fd560c6d2 user: drh tags: trunk)
2017-01-16
18:10
Back out check-in [0b3174e0b1364c] and replace it with a better fix for \ticket [91e2e8ba6ff2e2] - a fix that does not cause the problem identified by ticket [7ffd1ca1d2ad4ec]. Add new test cases for both tickets. (check-in: 9b64af7b52 user: drh tags: trunk)
16:43
Back out check-in [0b3174e0b1364c] and replace it with a better fix for ticket [91e2e8ba6ff2e2] - a fix that does not cause the problem identified by ticket [7ffd1ca1d2ad4ec]. (Closed-Leaf check-in: 0613665274 user: drh tags: automatic-index-affinity)
16:01
Add test cases for tickets [91e2e8ba6ff2e2] and [7ffd1ca1d2ad4ec]. (check-in: 9d0dfe0b08 user: drh tags: automatic-index-affinity)
2017-01-13
18:24
Fix a problem preventing resumption of RBU operations after recovering from a process or system failure that occurs during the incremental-checkpoint phase. (check-in: 97914266cb user: dan tags: trunk)
12:53
Fix the build for SQLITE_ENABLE_MEMORY_MANAGEMENT. (check-in: 8c85b8fdd7 user: drh tags: trunk)
2017-01-12
19:10
Remove a branch that is probably unreachable, and which adds no value. (check-in: 9acc72381c user: drh tags: trunk)
16:21
Fix harmless compiler warnings in the UPDATE code generator. (check-in: 385db26667 user: drh tags: trunk)
16:14
Remove an unnecessary corruption test from the btree balancer. If corruption is present, it will be found harmlessly by later tests. (check-in: bddf39562d user: drh tags: trunk)
15:11
Improved detection of cells that extend into the reserved space at the end of the page while adjusting overflow page pointers during autovacuum. (check-in: 8097712c9c user: drh tags: trunk)
11:52
Remove invalid test case from cursorhints2.test (check-in: 163cc1b2f7 user: drh tags: trunk)
11:50
Make sure Tcl_AppendResult() always has a NULL-pointer argument at the end. (check-in: c07aef6f90 user: drh tags: trunk)
