00:19
Fix recent test cases in test/indexepxr2.test so that they work even without SQLITE_ENABLE_STAT4 and SQLITE_ENABLE_JSON1. (check-in: 03f3cc03aa user: drh tags: trunk)
2017-09-01
14:50
Add the new sqlite3PagerUnrefPageOne() pager method to deal with the special case of unreferencing page1. (check-in: b2e2100cf7 user: drh tags: trunk)
12:57
Remove an obsolete optimization in pcache that due to more recent changes was recently making the code a little slower. (check-in: c4e7e175ee user: drh tags: trunk)
12:18
Small size and performance improvement in pcacheManageDirtyList() by not zeroing the PgHdr.pDirtyNext and PgHdr.pDirtyPrev pointers for PgHdr objects that are not on the dirty list. (check-in: 919863b148 user: drh tags: trunk)
2017-08-31
21:11
Clarify the documentation about "protected" versus "unprotected" sqlite3_value objects. No changes to code. (check-in: 4094a3410e user: drh tags: trunk)

2017-08-22
21:23
Update documentation to make it clear that SQLITE_SOURCE_ID and sqlite3_sourceid() might changes if the source code is edited. (check-in: e69c0c8770 user: drh tags: trunk)
21:07
Less dramatic changes to the source-id following an edit. Modify the way that the amalgamation is constructed to give it the opportunity to detect changes and modify the source-id. (check-in: 564c7340a3 user: drh tags: trunk)

Attempting to fix the source-id generator so that it works for out-of-tree builds. (check-in: 5a037ac2da user: drh tags: mksourceid)
19:19
Add the "mksourceid" program to the build process. That program changes the SQLITE_SOURCE_ID if the source tree has been modified in any way. (check-in: d4c05e04f7 user: drh tags: mksourceid)

14:34
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. (check-in: eb1202b5e4 user: drh tags: trunk)
08:29
Only use indexes on expressions to optimize ORDER BY and GROUP BY if the collation sequence matches. Possible fix for [e20dd54a]. (check-in: 37e1900880 user: dan tags: trunk)
2017-08-17
20:53

2017-08-16
19:20
Avoid a test for CURTYPE_BTREE in sqlite3VdbeCursorMoveto() in order to reduce the size and improve the performance of OP_Column. (check-in: f078deb251 user: drh tags: trunk)

2017-08-14
23:53
Minor size and performance optimization to sqlite3BtreeCloseCursor(). (check-in: 1696933884 user: drh tags: trunk)
18:13
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. (check-in: 240d57143d user: drh tags: trunk)
17:03
Fix harmless indentation error. (check-in: 25e92baaae user: drh tags: trunk)

Add extra tests to this branch. (check-in: b0e3b88a79 user: dan tags: writable-vtab-without-rowid)
17:53
Test case for writing to a WITHOUT ROWID virtual table. The TCLVAR virtual table is modified to add a "fullname" column which is the primary key, and to accept update operations against the primary key. (check-in: 6997e00c32 user: drh tags: writable-vtab-without-rowid)
15:19
Experimental changes that allow a WITHOUT ROWID virtual table to be writable as long as it has only a single-column PRIMARY KEY. (check-in: ab9ee4c1e6 user: drh tags: writable-vtab-without-rowid)

The identifier "vsnprintf" appears to be a reserved word in recent versions of XCode, so avoid using it as a structure field. (check-in: 795eede331 user: drh tags: trunk)
21:30
Fix a faulty signed/unsigned character comparison in the LIKE optimization logic. (check-in: f4a4b14973 user: drh tags: trunk)
20:03
Enhance the CSV virtual table extension so that it accepts the last row of the CSV file even if the last row omits the closing \n, as long as the last row has a full set of columns. (check-in: 537e3be2e9 user: drh tags: trunk)
2017-08-07
19:12
