| 23:05 | Fix the built-in edit() SQL function in the CLI so that it works with zero-length blobs. check-in: e3249012 user: drh tags: trunk | |
| 21:11 | Attempt to parse the NULLS LAST clause more efficiently. A few cycles were saved, but at the expense of more code. And there is a bug was introduced somewhere. Not worth continuing down this line. Closed-Leaf check-in: 12d2cf88 user: drh tags: dead-end | |
| 20:33 | Move some things in parse.y so that TK_COLUMN and TK_AGG_COLUMN are assigned the same values as they are on trunk for a very small speedup. Leaf check-in: d26fdfa3 user: dan tags: nulls-last | |
| 17:09 | Revise the VDBE comments for NULL-scan so that they also work make sense when reading a NULLS FIRST plan. check-in: bfe79378 user: drh tags: nulls-last | |
| 17:00 | Additional simplifications of the WHERE loop code generator logic for NULLS LAST. check-in: 1383680d user: drh tags: nulls-last | |
| 16:12 | Simplification of the WHERE loop code generator for NULLS LAST saves a few CPU cycles and about a hundred bytes of code space. check-in: e3ed2f49 user: drh tags: nulls-last | |
| 13:32 | Invert the meaning of the regBignull flag so that it is 1 when doing the normal scan and 1 when scanning nulls. This enables the re-do jump at the bottom of the loop to be coded with a single OP_IfNotZero opcode, rather than a sequence of OP_If, OP_Integer, OP_Goto. check-in: bf875e1a user: drh tags: nulls-last | |

| 16:36 | Experimental implementation of NULLS FIRST/LAST. This branch still has problems - the most significant of which is that ORDER BY clauses with a non-default NULLS FIRST/LAST qualifier can never use an index. check-in: 07babb0f user: dan tags: nulls-last | |
| 16:25 | For the ".testctrl prng_seed" command in the CLI, if the argument is "random" then select a random integer seed and print the seed value on stdout. check-in: 636ca447 user: drh tags: trunk | |
| 15:37 | Fix the build for compilation using separate files rather than the amalgamation. Leaf check-in: 1e0f4869 user: drh tags: sha3 | |

| 15:06 | Fix the sqliteExprImpliesExpr() routine so that it recognizes that "(NULL IS FALSE) IS FALSE" doe not imply "NULL NOT NULL". Ticket [9080b6227fabb466] check-in: da01ba4f user: drh tags: trunk | |
| 14:35 | Add extra test cases related to the previous commit. check-in: 3c690b2b user: dan tags: trunk | |

2019-08-08
| ||
| 19:40 | Fix harmless compiler warnings. check-in: 1eef4dde user: drh tags: trunk | |
| 19:19 | Remove support for SQLITE_ENABLE_STAT3. The sqlite_stat3 table is now ignored, if it exists. Run ANALYZE using STAT4 to get the equivalent functionality, which presumably everybody has been doing for a long time now. check-in: f1cd234c user: drh tags: trunk | |
| 18:49 | Fix a case of the Expr.affinity to Expr.affExpr refactor that was missed in the [a29f2a7d07beff64] check-in. check-in: 83450d10 user: drh tags: trunk | |
| 16:23 | More legacy STAT3 code removed. Closed-Leaf check-in: 845d2f17 user: drh tags: omit-stat3 | |
| 15:47 | Fix spurious "no such table: x1" errors in shared-schema mode that could occur when a query that is a join across two or more databases needs to call the xConnect() methods of a virtual table. check-in: edf45cd7 user: dan tags: reuse-schema | |
| 15:24 | Remove support for STAT3. The sqlite_stat3 tables are ignored, if they exist. STAT4 continues to work as it always has, and as it is a superset of STAT3 is the recommended replacement. check-in: 1e17ea2f user: drh tags: omit-stat3 | |
| 11:44 | Fix a bug causing "no such table" and other similar sqlite3_prepare*() errors to return SQLITE_SCHEMA instead of SQLITE_ERROR in shared-schema mode when there is an attached database for which the schema has never been loaded. check-in: 111e2c73 user: dan tags: reuse-schema | |
| 01:39 | Remove a NEVER() that is reachable from a corrupt database. check-in: 30e6ee27 user: drh tags: trunk | |
|
2019-08-07
| ||
| 19:57 | Remove use of the affinity() function from view.test, as it is only available in SQLITE_DEBUG builds. check-in: 7f2246a1 user: dan tags: trunk | |
| 18:34 | Add "set TMP=%CD%" to the start of each msvc script output by releasetest_data.tcl. Otherwise, since binaries compiled with SQLITE_TEST all choose the same sequence of pseudo-random numbers, collisions between temp file names cause errors when running multiple tests in parallel. check-in: f5d0436d user: dan tags: trunk | |
| 17:45 | Eliminate some more cases of redundant sorting in window-function queries. check-in: 8158d2ac user: dan tags: trunk | |
| 13:25 | Do not make SQLITE_READ authorizer calls for tables without names, as all such tables will be internal-use-only tables for subqueries and whatnot. check-in: 193c87fc user: drh tags: trunk | |
|
2019-08-06
| ||
| 21:16 | Ensure that when the col in an operator like "val IN(col)" is a column of a view, its affinity is not used to coerce val. Fix for [0a5e2c1d]. check-in: 17b3d221 user: dan tags: trunk | |
| 20:55 | Improved reuse of file descriptors for which close() is delayed to prevent clearly of posix advisory locks. check-in: 509c1ba2 user: drh tags: trunk | |
| 20:26 | Enhance the ".recover" output in the shell to use double-quotes around table and column identifiers. check-in: 846d2d2d user: drh tags: trunk | |
| 18:40 | Add "PRAGMA foreign_keys=OFF;" to the start of the script output by ".recover", just as is done for ".dump". check-in: bfc29e62 user: dan tags: trunk | |
| 15:32 | Ensure that columns of views and sub-queries that are expressions with no affinity are comparied without any type conversions, as required in the documentation. Tickets [61c853857f40da49] and [d52a29a9e6bc55c5]. check-in: 9c8c1092 user: drh tags: trunk | |
| 15:18 | Performance optimization to the new affinity handling logic. Closed-Leaf check-in: c9724e76 user: drh tags: pending | |
| 15:02 | Add a multi-threaded test to threadtest3.c for the feature on this branch. check-in: 62557fab user: dan tags: reuse-schema | |
| 14:37 | Use 0x40 (ASCII '@') instead of 0x00 to mean "no affinity" so that columns with no affinity can appear in a zero-terminated string. Use the new SQLITE_AFF_NONE macro for this new magic number. check-in: e8234f69 user: drh tags: pending | |
| 11:45 | Add an assert() to the code on this branch. check-in: fdd44bbb user: dan tags: reuse-schema | |
|
2019-08-05
| ||
| 20:53 | Ensure that columns of views and sub-queries that are expressions with no affinity are not assigned BLOB affinity. This matches the documentation. Fix for [61c853857f40da49]. (On a branch because there are still subtle issues.) check-in: e15a0977 user: dan tags: pending | |
| 20:45 | Add test cases to this branch. Closed-Leaf check-in: f37317d8 user: dan tags: tkt-61c853-A | |
| 19:44 | Fix the patch on this branch so that it works with sub-queries, as well as views. check-in: 7480db30 user: dan tags: tkt-61c853-A | |
| 19:34 | The second option for [61c853857f40da49]: In this mode, columns of VIEWs and subqueries that are formed by expressions have affinity BLOB rather than affinity none, as has usually been the case for a while. But this mode fixes a couple of corner cases involving query flattening and the push-down optimization where that rule was violated. Closed-Leaf check-in: 470ac8d5 user: drh tags: tkt-61c853-B | |
| 19:32 | One of two options on how to address ticket [61c853857f40da49]. In this mode, we back out the documentation change of [07b7749da88d54e5] and change the core to work as it has been documented to work since 2017, rather than how it has actually worked since 2009. check-in: 09cd0c0c user: drh tags: tkt-61c853-A | |
| 18:01 | Refactor field Expr.affinity into Expr.affExpr to avoid confusion with other fields and variables named "affinity" and display affExpr it in sqlite3TreeViewExpr() output. check-in: a29f2a7d user: drh tags: trunk | |
| 16:22 | Improved detection of corruption on the freeblock list of a btree page. check-in: 4b00799b user: drh tags: trunk | |
| 13:19 | Fix a problem with renaming a table when a view or trigger within the schema uses a FILTER with an aggregate function that is not currently registered with the database. check-in: 2ac0e42f user: dan tags: trunk | |
| 12:55 | Prevent an fts5 table from being its own content table, or part of a view that is the content table. check-in: b6d52c93 user: dan tags: trunk | |

| 16:17 | In the ".wheretrace 0x100" debugging mode, show the structure of the main parameters to sqlite3WhereBegin() calls. check-in: fd598e47 user: drh tags: trunk | |
| 01:40 | Add the SQLITE_TESTCTRL_PRNG_SEED which can control the PRNG seed either directly or through the schema cookie of a supplied database connection. check-in: 2660e929 user: drh tags: trunk | |
| 01:39 | Give the SQLITE_TESTCTRL_PRNG_SEED two arguments. The second argument if not NULL is a pointer to a database connection which seeds the connection from its schema cookie. In this way, fuzzers can control the PRNG seed. Closed-Leaf check-in: 49aa3448 user: drh tags: prng-seed-test-control | |

| 19:40 | If a query like "SELECT min(a), b FROM t1" visits no rows where "a" is not null, extract a value for "b" from one of the rows where "a" is null. Fix for ticket [41866dc37]. check-in: faaaae49 user: dan tags: trunk | |
| 18:43 | If a query like "SELECT min(a), b FROM t1" visits no rows where "a" is not null, extract a value for "b" from one of the rows where "a" is null. Possible fix for ticket [41866dc37]. Closed-Leaf check-in: a7277ed0 user: dan tags: tkt-41866dc37 | |

| 22:48 | The sqlite3_set_authorizer() interface should only expire prepared statements when it is setting a new authorizer, not when clearing the authorizer.

| 21:00 | Fix the build for when -DSQLITE_SMALL_STACK is used. check-in: b9eda224 user: drh tags: trunk | |
| 14:22 | Improved fix for ticket [ced41c7c7d6b4d36] that keeps skip-scan enabled, but avoids identifying a skip-scan as order-distinct (because it is not) and thus forces a separate b-tree to implement the DISTINCT clause of a query. This undoes check-in [a871d69c6de65038] and substitutes a new fix. check-in: 89bf0399 user: drh tags: trunk | |
