[56d19f9f] Leaf: Remove an unnecessary conditional. (user: drh, tags: trunk)
02:05
[6538ef7b] Minor optimization to sqlite3VdbeMemSetStr(). (user: drh, tags: trunk)
2017-08-19
20:38
[d01d2cff] Space and size optimization to the printf implementation. (user: drh, tags: trunk)
2017-08-18
22:30
[745bc8de] Another size and performance optimization to readDbPage(). This time we eliminate some unnecessary local variables. (user: drh, tags: trunk)
21:14
[ca9e1875] Size and performance optimization the readDbPage() routine in the pager. (user: drh, tags: trunk)
16:09
[3075cfa0] For the unix VFS, avoid an unnecessary stat() system call prior to opening any file in the common case where there are no unused file descriptors. (user: drh, tags: trunk)
14:34
[eb1202b5] Combine the OP_CreateTable and OP_CreateIndex opcodes of the bytecode engine into a single OP_CreateBtree opcode. This simplifies the implementation and makes the bytecode programs clearer. (user: drh, tags: trunk)
08:29
[37e19008] Only use indexes on expressions to optimize ORDER BY and GROUP BY if the collation sequence matches. Possible fix for [e20dd54a]. (user: dan, tags: trunk)
2017-08-17
20:53
[a42a438c] Use the __builtin_clzll() function of gcc to improve the performance and reduce the size of the sqlite3LogEst() routine. (user: drh, tags: trunk)
19:23
[264a5e1b] Small optimization in the Expr tree walker. (user: drh, tags: trunk)
18:54
[0367a4d5] Size optimization in the authorizer error message generation logic. (user: drh, tags: trunk)
18:23
[f13682ea] In sqlite3ViewGetColumnNames(), return the number of errors, not an error code. (user: drh, tags: trunk)
18:17
[0712f057] The RTREE extension should return SQLITE_CORRUPT_VTAB, not just SQLITE_CORRUPT when it encounters incorrectly formatted shadow tables. (user: drh, tags: trunk)
14:47
[fb6ca99b] Remove an unnecessary branch from the [be436a7f4587ce517ddc] fix. (user: drh, tags: trunk)
14:12
[2101b420] Add test cases for ticket [be436a7f4587ce517] using virtual table modules fts5 and rtree. (user: dan, tags: trunk)
02:26
[a7bc7752] Defer schema resets when the query planner is running. Proposed fix for ticket [be436a7f4587ce517]. (user: drh, tags: trunk)
2017-08-16
19:20
[f078deb2] Avoid a test for CURTYPE_BTREE in sqlite3VdbeCursorMoveto() in order to reduce the size and improve the performance of OP_Column. (user: drh, tags: trunk)
14:16
[39543903] Remove an unnecessary local variable from OP_Column, for a small size reduction and performance increase. (user: drh, tags: trunk)
11:04
[dc98a92f] Performance improvement in the OP_Column opcode. (user: drh, tags: trunk)
2017-08-15
14:14
[2cf3f3de] Small size and performance improvement in the OP_Column opcode. (user: drh, tags: trunk)
03:46
[373b71d1] Btree optimization: New field BtCursor.pPage that points to the current page, saving a single pointer dereference on each access. (user: drh, tags: trunk)
2017-08-14
23:53
[16969338] Minor size and performance optimization to sqlite3BtreeCloseCursor(). (user: drh, tags: trunk)
18:13
[240d5714] Change the internal btree routine moveToRoot() to return SQLITE_EMPTY if the table is empty or if it has pgnoRoot==0. This simplifies the callers, making them smaller and faster. The SQLITE_EMPTY result code is intercepted and changed into SQLITE_OK before surfacing in an API. (user: drh, tags: trunk)
17:03
[25e92baa] Fix harmless indentation error. (user: drh, tags: trunk)
14:53
[d0da791b] Sometimes a TK_COLUMN Expr node can have Expr.pTab==0 if it is a reference to an expression column in an index on an expression. Fix for ticket [aa98619ad08ddcab]. (user: drh, tags: trunk)
01:33
[7e0d3e9c] Properly dequote column names in tables constructed by an aggregate SELECT. (user: drh, tags: trunk)
2017-08-12

02:16
[14d262d6] Update the speed-check.sh test script to append log output to the end of the cout-NAME.txt file. (user: drh, tags: trunk)
02:01
[6e52fa5f] Remove the zBase field from the StrAccum object. Resulting code is slightly smaller and faster. (user: drh, tags: trunk)
01:09
[28a5aec1] Size and performance micro-optimization on sqlite3SrcListIndexedBy(). (user: drh, tags: trunk)
2017-08-11

[831156a4] Fix compiler warnings that arise if the PAGERTRACE macro is turned on. This changes does not affect production builds. (user: drh, tags: trunk)
