Draw the TreeView debugging graphs using unicode box-drawing characters. (Closed-Leaf check-in: 0efc6859 user: drh tags: box-character-graph)
19:04
Improvements to the new syntax-tree output routines: Omit the "END SELECT" mark and instead terminate the graph at the last item. Increase the maximum tree depth to 100. (check-in: 5ce05757 user: drh tags: trunk)
17:31
Enable the query planner to deal with WHERE clauses that have OR terms nested within AND terms that are nested within OR terms. Also remove an unused function declaration. (check-in: b6b28918 user: drh tags: trunk)

Further enhancements to the "wheretrace" debugging output. (check-in: 670993eb user: drh tags: trunk)

12:33
Remove the SQLITE_ENABLE_TREE_EXPLAIN compile-time option. Add alternative debugging display routines: sqlite3TreeViewExpr(), sqlite3TreeViewExprList(), and sqlite3TreeViewSelect(). (check-in: 4ff51325 user: drh tags: trunk)
2014-09-29
18:47
Add the OPFLAG_MULTICOLUMN flag to the OP_Column opcode. Rearrange OP_Column instructions to take advantage of the new flag for a small performance increase (Leaf check-in: 5e5d6e86 user: drh tags: faster-OP_Column)

2014-09-27
20:45
Change the names of the stream interface APIs to be of the form "_strm" instead of "_str". In other words, added an "m" to the end, to try to make it clear that we are talking about a "stream" and not a "string. (check-in: 1f44bfdc user: drh tags: sessions)
19:51
Merge recent trunk changes (performance enhancements) into the sessions branch. (check-in: 497367cb user: drh tags: sessions)

Add an assert() to verify the last-row-id for the database just prior to calling a SQL function. (check-in: d026f0c9 user: mistachkin tags: trunk)
02:41
Fix the "PRAGMA integrity_check" command so that it avoids formatting error message context messages until it actually needs to generate an error message. This avoids much formatting, and hence greatly improves the performance of "PRAGMA integrity_check" in the common case when there are no errors. It also makes the code a little smaller. (check-in: 83913515 user: drh tags: trunk)
01:10
If an SQL function makes a recursive call to do an INSERT into the same database, make sure that the last_insert_rowid() for that INSERT is recorded. (check-in: e93aecc0 user: drh tags: trunk)
2014-09-25
17:42
Minor code reformatting and comment change, to improve clarity. No logic changes. (check-in: baeb72a3 user: drh tags: trunk)
13:17
Simplifications to the SQL function and aggregate calling procedures. (check-in: 3467049a user: drh tags: trunk)

11:08
Still more performance enhancements to the LIKE and GLOB operators. (check-in: 6c8924ca user: drh tags: trunk)
03:51
More performance optimization for the LIKE and GLOB operators. (check-in: 5ab1023d user: drh tags: trunk)
02:44
Change that might allow SQLite to build and work using the EBCDIC character set. (check-in: ef30e035 user: drh tags: trunk)
00:56
Size reduction and performance improvement in the LIKE and GLOB operators. (check-in: b2c89ef4 user: drh tags: trunk)
2014-09-24
19:47
Have each open database allocate its pTmpSpace when the first write cursor is opened, rather than on each insert or delete, for a small space savings and performance boost. (check-in: 99323552 user: drh tags: trunk)
18:31
Small performance and size optimization for btreeUnlockIfUnused(). (check-in: 13c746f8 user: drh tags: trunk)
