| 00:33 | Begin reengineering the EXPLAIN QUERY PLAN function to provide more intuitive output. (check-in: 70b48a7972 user: drh tags: rework-EQP) | |
|
2018-05-01
| ||
| 18:39 | The SQLITE_ALLOW_SQLITE_MASTER_INDEX compile-time option allows a CREATE INDEX statement against the sqlite_master table. Once created, the index works, and is usable by legacy instances of SQLite. (check-in: 853f316359 user: drh tags: trunk) | |
| 01:18 | The ".selecttrace 0x4000" command causes the AST to be output to stdout as a table with four columns. (Leaf check-in: 2a75e631ee user: drh tags: ast-trace-demo) | |
|
2018-04-30
| ||
| 19:32 | Defer loading result column values into registers on an ORDER BY LIMIT until we know that the LIMIT does not exclude the current row. (Closed-Leaf check-in: ce4ef46058 user: drh tags: faster-order-by-limit) | |
|
2018-04-28
| ||
| 19:08 | Test cases added for SQLITE_DBCONFIG_RESET_DATABASE. (check-in: 08665a9e2e user: drh tags: trunk) | |
| 18:20 | Fix an RBU problem causing spurious SQLITE_CONSTRAINT errors when restarting an RBU update in which more than one source table writes to a single target database table. (check-in: 564ae8297d user: dan tags: trunk) | |
| 13:21 | Add the SQLITE_DBCONFIG_RESET_DATABASE control for resetting a corrupt database file without closing any database connections. Added the ".dbconfig" command to the CLI. (check-in: a200a49ede user: drh tags: trunk) | |
| 12:43 | Add the SQLITE_DBCONFIG_RESET_DATABASE control as a replacement for the reset_database pragma. Resetting the database should be hard enough to do that it cannot be done by accident. (Leaf check-in: ff836cb8b0 user: drh tags: reset-database) | |
| 11:22 | Merge updates from trunk. (check-in: 94877e495c user: drh tags: reset-database) | |
| 04:16 | Prevent deep recursions on nested COLLATE operators. (check-in: 6e098ee415 user: drh tags: trunk) | |
| 04:10 | Fix compiler warnings in FTS3. (check-in: de508e831a user: drh tags: trunk) | |
| 01:48 | Document and expose sqlite3_win32_set_directory() function for use on Win32. (check-in: f677065aab user: mistachkin tags: branch-3.23) | |
| 01:46 | Document and expose sqlite3_win32_set_directory() function for use on Win32. (check-in: 7626b59340 user: mistachkin tags: trunk) | |
| 01:44 | Add comments about the intended use of the sqlite3_data_directory variable as it pertains to the sqlite3_win32_set_directory function. (Closed-Leaf check-in: d11c419756 user: mistachkin tags: win32dir) | |
| 01:37 | Bump the version number to 3.23.2. (check-in: 242dc910b0 user: drh tags: branch-3.23) | |
| 01:27 | Add the "PRAGMA reset_database=ON|OFF" command. When on, it causes the database to appear to be empty, causing the next transaction to reset it to an empty database. (check-in: 02e1a13c1f user: drh tags: reset-database) | |

| 22:42 | Document and expose sqlite3_win32_set_directory() function for use on Win32. (check-in: cbce7180ee user: mistachkin tags: win32dir) | |
| 20:49 | Better comments on the bindvtab.c implementation. All the two-argument version of the .set command. All bindings from .set and -D are still string. (Leaf check-in: 7b2a65a654 user: drh tags: shell-bindings) | |
| 18:05 | Update test script fts3expr4.test so that it always creates fts3 tokenizers in the "en_US" locality. (check-in: 576a8f69ae user: dan tags: trunk) | |
| 17:39 | Add the ability to use bind parameters in the CLI. The new ".set KEY=VALUE" dot-command works to set bindings. Or use the "-Dkey=value" command-line option. Or use the built-in shell_bindings(k,v) virtual table to set, delete, or changing bindings. (check-in: 1f2944d1d6 user: drh tags: shell-bindings) | |
| 16:35 | Fix a test script error causing tests to fail in soak.test. (check-in: 462b52b121 user: dan tags: trunk) | |
| 15:17 | Enhance the comments in the templatevtab.c implementation. (check-in: 05f6278a02 user: drh tags: trunk) | |

| 18:34 | The previous fix for ticket [d85fffd6ffe856092ed8da] in check-in [0a514e62ad1ebe5c12da8dae] did not completely address the probably in that it only worked for cases where the OP_SCopy that loaded the register was the last instruction in the sequence for the expression, which is not necessarily the case for expressions like CASE...END. This revision prevents the registered that will be recomputed from being cached in the first place. (check-in: 9fd0faf517 user: drh tags: trunk) | |
| 18:01 | Merge latest changes from trunk. Including the "ORDER BY ... LIMIT" optimization. (check-in: 83a4c9f088 user: dan tags: begin-concurrent-pnu) | |
| 17:54 | Merge latest changes from trunk. Including the "ORDER BY ... LIMIT" optimization. (check-in: d8ae7ba083 user: dan tags: begin-concurrent) | |
| 17:43 | When processing an "ORDER BY ... LIMIT" that does not use an index, check whether or not a record may appear in the final result set before adding it to the temp b-tree used for sorting. (check-in: 0fcfc36ceb user: dan tags: trunk) | |
| 16:13 | When processing an "ORDER BY ... LIMIT" that does not use an index, check whether or not a record may appear in the final result set before adding it to the sorter. (Closed-Leaf check-in: 71bf91c218 user: dan tags: sorter-limit-opt) | |
| 15:50 | Ensure that new.* values of an UPDATE do not get clobbered after the BEFORE triggers run when unmodified columns of the row being updated are reloaded. Fix for ticket [d85fffd6ffe856092ed8da] (check-in: 0a514e62ad user: drh tags: trunk) | |
| 15:04 | Clarification of the behavior of a BEFORE UPDATE trigger when the trigger changes the values of some of the columns used to compute new columns in the UPDATE. (check-in: 7bb23c2a3d user: drh tags: trunk) | |
| 12:27 | Improved VDBE comment on the OP_Param opcode. No substantial changes. (check-in: 368c14da86 user: drh tags: trunk) | |
| 08:56 | Update the "fuzz_malloc.test" script to print SQL statements in which OOM handling problems are found to stdout. (check-in: a956363cf6 user: dan tags: trunk) | |
|

| 19:02 | Add new interfaces for accessing the list of SQL keywords: sqlite3_keyword_count(), sqlite3_keyword_name(), sqlite3_keyword_check(). (check-in: 7dd34e3776 user: drh tags: trunk) | |
| 17:10 | Add the new DO and NOTHING keywords to the keyword lists maintained by various extensions and auxiliary programs. (check-in: 77a98a0781 user: drh tags: trunk) | |
| 13:27 | Add the new SQLITE_SHELL_INIT_PROC compile-time entry point to the CLI. This is needed to work around the tighter sqlite3_config() constraints now in the CLI. (check-in: 3bcdbccf53 user: drh tags: trunk) | |
| 12:01 | Avoid many unnecessary calls to sqlite3ReadSchema() and sqlite3Init() when the schema is known to be valid already. (check-in: 58cf812fd8 user: drh tags: trunk) | |
| 10:30 | Add an assert() to ensure that schema mutexes are held prior to accessing the DB_SchemaLoaded flag inside of sqlite3Init(). (check-in: d8b46290bb user: drh tags: trunk) | |

| 19:22 | Update this branch with latest changes from trunk. (check-in: 2d8d13e4a1 user: dan tags: begin-concurrent-pnu) | |
| 19:21 | Merge latest trunk changes into this branch. (check-in: b27bd799ea user: dan tags: begin-concurrent) | |
| 18:59 | Remove a recently added NEVER() macro from a branch that can be taken in obscure circumstances. (check-in: 2aa210030a user: dan tags: trunk) | |
| 18:53 | Fix a problem with processing "LEFT JOIN tbl ON tbl.a = ? AND (tbl.b=? OR tbl.c=?)" in cases where there are indexes on both tbl(a, b) and tbl(a, c). (check-in: ce35e39c5c user: dan tags: trunk) | |
| 17:34 | Do not attempt to use terms from the WHERE clause to drive indexes on the right table of a LEFT JOIN. Fix for ticket [4ba5abf65c5b0f9a96a7a40cd18b] (check-in: aeb694e3f7 user: drh tags: trunk) | |
| 16:51 | Update the expert extension test cases to account for the fact that EXPLAIN QUERY PLAN now shows the start of each trigger in its output. (check-in: 8acb42f489 user: drh tags: trunk) | |
| 16:41 | All the OR optimization to proceed even if the OR is also converted into an IN operator. (check-in: e252c6540d user: drh tags: trunk) | |
| 14:18 | Add a hyperlink to the ticket on the code comment for the fix to ticket [7fa8049685b50b5aeb0c2]. (check-in: 45247c7f29 user: drh tags: trunk) | |
| 14:05 | Do not attempt to read values from indexes-on-expressions if the index is on the RHS of a LEFT JOIN. This won't work if the index cursor points at a null-row. Fix for [7fa80496]. (check-in: b8ef967ab1 user: dan tags: trunk) | |
| 13:07 | Enhance the CLI to render EXPLAIN QUERY PLAN using an ASCII-art graph. This works with ".eqp" modes and when the query begins with exactly "EXPLAIN QUERY PLAN". To see the original output format, add extra space characters in between words of the initial "EXPLAIN QUERY PLAN". (check-in: f53716ee2a user: drh tags: trunk) | |
| 10:57 | Fix a memory leak following failure to open an external CSV file in the csv.c extension. (check-in: 526ee07d19 user: drh tags: trunk) | |
| 01:10 | In EXPLAIN QUERY PLAN output, do not show an EXECUTE LIST SUBQUERY line for IN operators where the RHS is a list and not a subquery, since in that case there is no SUBQUERY to execute. (check-in: 8bc0207abd user: drh tags: trunk) | |
| 00:08 | Fix to check-in [ca34c2dd20ee071e] - avoid a NULL pointer dereference following an OOM. (check-in: c7e6e848fa user: drh tags: trunk) | |
|
