25 check-ins using file src/where.c version 74b0a054
2017-07-07
| ||
22:39 | Fix test cases in wal2.test due to the fact that Darwin checks to see if the SHM file is writable before attempting to open in read/write. (check-in: 6b618b18 user: drh tags: apple-osx) | |
20:33 | Avoid even trying to open a SHM file read/write in WAL mode if we know that the file is read-only. This avoids scare security log messages. (check-in: d9d92781 user: drh tags: apple-osx) | |
2017-06-29
| ||
12:49 | Add the SQLITE_STMTSTATUS_REPREPARE and SQLITE_STMTSTATUS_RUN options to sqlite3_stmt_status(). Use this for two new columns in the stmts virtual table. (Closed-Leaf check-in: b0b0c8f8 user: drh tags: stmts-vtab) | |

| ||
17:29 | Instead of the new sqlite3_prepare_v3() interface, provide the SQLITE_DBCONFIG_PREPARE_FLAGS interface which sets the flags on the single next call to sqlite3_prepare_v2() or its cousins. (Closed-Leaf check-in: 942c3ef8 user: drh tags: dbconfig-prepare-flags) | |
15:56 | Incorporate recent trunk changes. (Closed-Leaf check-in: 62b8269b user: drh tags: prepare_v3) | |
15:47 | Build the "stmts" virtual table into the amalgamation. It is active only when compiled using SQLITE_ENABLE_STMTSVTAB. That option is supplied to the command-line shell. (check-in: 0ff057d8 user: drh tags: stmts-vtab) | |
15:17 | Fix harmless compiler warnings in the CSV extension. (check-in: f02a5459 user: drh tags: trunk) | |
15:01 | Faster parser stack overflow detection. (check-in: 36e54cd8 user: drh tags: trunk) | |
14:26 | Minor tweak to the SQL grammar to make the parser tables a few bytes smaller. (check-in: cc4810b2 user: drh tags: trunk) | |
13:47 | In the lemon-generated parser, store the number of symbols on the RHS of each rule as a negative number and add it to the stack pointer, rather than storing the value as a positive and subtracting it. This makes the parser faster. (check-in: b362f0d8 user: drh tags: trunk) | |
11:56 | In the lemon-generated parser, automatically promote SHIFTREDUCE actions on nonterminal systems to pure REDUCE actions, for a performance enhancement. (check-in: c46d94a8 user: drh tags: trunk) | |
01:21 | Simplify error handling logic in sqlite3_exec() to save about 40 bytes. (check-in: 6480916c user: drh tags: trunk) | |
01:12 | Minor code simplification in the ALTER TABLE logic. (check-in: bfc4e7f3 user: drh tags: trunk) | |
00:55 | Avoid an unnecessary call to sqlite3XPrintf() in the code generator, for a performance improvement. (check-in: 29d6ceb3 user: drh tags: trunk) | |
2017-06-27

23:36 | Add SQLITE_DBCONFIG_ENABLE_QPSG that forces the query planner stability guarantee. This is the fix for ticket [b9f010107724c] (check-in: b82efd2a user: drh tags: trunk) | |
16:48 | Merge latest trunk changes with this branch. (check-in: 2b095406 user: dan tags: apple-osx) | |
16:39 | Fix a virtual table problem that can occur when the vtab is on the RHS of a LEFT JOIN and there is a MATCH constraint in the ON clause, or when the vtab is in a sub-query that is the RHS of a LEFT JOIN and there is a MATCH constraint in the WHERE clause of the sub-query. (check-in: 87b38166 user: dan tags: trunk) | |
2017-06-26
| ||
21:08 | Add the -withoutnulls option to the "db eval" method in the TCL interface. (check-in: 18f0616e user: drh tags: trunk) | |
18:42 | The ".import" command of the shell, and the csv virtual table extension both ignore a single UTF-8 BOM at the beginning of their input. (check-in: 7c15d762 user: drh tags: trunk) | |
16:13 | Add the "-unsetnull 1" option to the "sqlite3" command in the TCL interface. (Closed-Leaf check-in: cbe441b2 user: drh tags: unsetnull-option) | |
14:46 | Make sure sqlite3VdbeSetVarmask() is never invoked when QPSG is enabled. (Closed-Leaf check-in: ebcfa73e user: drh tags: enable-QPSG) | |
13:57 | Add the SQLITE_DBCONFIG_ENABLE_QPSG option to activate the query planner stability guarantee. This involves refactoring the sqlite3.flags bitvector to carve out a free bit to use. (check-in: 7076e828 user: drh tags: enable-QPSG) | |
2017-06-24

19:21 | Disable shell tests for the .schema command if virtual tables are not available. (check-in: c8186874 user: drh tags: trunk) | |
16:35 | Make sure the config.h header is included by ctime.c, if that header exists. (check-in: c2ea6293 user: drh tags: trunk) | |
16:03 | Query planner tuning: When deciding between two plans with the same cost, bias the selection toward the one that does not use the sorter. (check-in: f0ec36d4 user: drh tags: trunk) | |
