30 check-ins using file src/vdbeaux.c version b9772e41

19:27
Size and performance optimization to sqlite3ValueFromExpr() check-in: 945f82bc user: drh tags: trunk
15:53
Clarification and typo-fixes in comments. No changes to code. check-in: e2cd79aa user: drh tags: trunk
2016-09-28
20:42
Use Knuth multiplicative hashing for the symbol table. check-in: cc29ddd6 user: drh tags: trunk
16:15
Merge recent enhancements from trunk. check-in: 06014163 user: drh tags: apple-osx
16:05
Two more typo fixes in comments. check-in: 40c0fb0a user: drh tags: trunk
16:04
Fix typos in comments. No code changes. check-in: 5bbd071d user: drh tags: trunk
2016-09-27
00:09
Update requirements marks due to improvements in the wording of documentation. No changes to code. check-in: bf903b2e user: drh tags: trunk
00:03
Fix FTS3 test cases due to the flattener change of the previous check-in. check-in: 0c8b9b21 user: drh tags: trunk
2016-09-26
14:39
When flattening a query of the form "SELECT * FROM (SELECT * FROM tbl WHERE x=?) WHERE y=?", ensure that the final WHERE clause is "x=? AND y=?" instead of "y=? AND x=?". Although it is still not guaranteed, this makes the order in which WHERE clause terms are processed comport more closely to users expectations. check-in: cf7f9e6d user: dan tags: trunk
12:38
Inline the relevent parts of sqlite3ExprAlloc() into spanExpr(), for a performance improvement. check-in: fe89225e user: drh tags: trunk
2016-09-24
17:42
Omit the LikeOp object from the parser. Change more sqlite3PExpr() calls into sqlite3ExprAlloc() calls. check-in: 795454a3 user: drh tags: trunk
01:41
Add -DSQLITE_MAX_EXPR_DEPTH=0 to the --lean option on speed-check.sh. check-in: a8cb1390 user: drh tags: trunk
2016-09-23
21:36
Add the EP_Leaf flag bit to the Expr.flags field to indicate Expr nodes that do not have substructure. Use that bit to avoid unnecessary recursion. check-in: 8a6ea455 user: drh tags: trunk
20:59
Use sqlite3ExprAlloc() instead of sqlite3PExpr() for leaf nodes in the expression tree, where appropriate. This is both smaller and faster. check-in: afac0709 user: drh tags: trunk
18:13
New test case for the ORDER BY LIMIT optimization. check-in: 9a5a489d user: drh tags: trunk
2016-09-22
21:37
Fix a potential null-pointer dereference and crash in the case where one thread is calling sqlite3_column_text() and another thread is calling sqlite3_step() on the same prepared statement at the same instant. check-in: ee1382a3 user: drh tags: trunk
18:53
Remove the internal sqlite3CodeOnce() interface, replacing it with a direct call to sqlite3VdbeAddOp0(v,OP_Once). Slightly smaller and faster. check-in: c3774c6a user: drh tags: trunk
18:46
Makefile changes to support building winsqlite3.dll using STDCALL rather than CDECL. check-in: 5e892d60 user: mistachkin tags: trunk
2016-09-21
23:58
Fix speedtest1.c so that it works with SQLITE_OMIT_DEPRECATED. Add the --lean and --cachesize options to speed-check.sh. check-in: 7785b3a2 user: drh tags: trunk
19:43
Fix a problem with the fts5 auxiliary function API causing a crash when a query contained a phrase of zero terms. check-in: 0741812d user: dan tags: trunk
19:00
Do not run vacuummem.test if ENABLE_MEMORY_MANAGEMENT is defined. check-in: 4a613d85 user: dan tags: trunk
18:18
Fix obsolete requirements marks. Add new tests for VACUUM of attached databases. check-in: 2b44f9aa user: drh tags: trunk
17:53
Avoid running vacuum5.test in auto-vacuum mode. check-in: be184bef user: dan tags: trunk
17:47
Do not run test "delete_db.test" with either the journaltest or inmemoryjournal permutations. Ensure that the multiplexor tests in delete_db.test are performed in non-autovacuum mode. check-in: 46b7d19e user: dan tags: trunk
14:41
Update the fts5vocab table to handle "ORDER BY term" efficiently. check-in: d4928fb5 user: dan tags: trunk
2016-09-20
22:04
Improved implementation of 64-bit signed integer multiply that correctly detects overflow (and promotes to floating-point) in some corner cases. Fix for ticket [1ec41379c9c1e400] check-in: db3ebd7c user: drh tags: trunk
17:49
Fix harmless compiler warning. check-in: 72429063 user: mistachkin tags: trunk
17:38
Fix typo in comment. check-in: bd3ecbb5 user: mistachkin tags: trunk
01:46
Further performance enhancements in zeroblob() handling. check-in: 21b0e3b7 user: drh tags: trunk
01:19
Avoid unnecessary calls to ExpandBlob() for smaller and faster code. check-in: 5e196fd1 user: drh tags: trunk
