| 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) | |

| 01:59 | Modify signature of sqlite3VdbeChangeOpcode() to accept int instead of u32. (check-in: 68b7f2ac user: mistachkin tags: trunk) | |
| 01:11 | Fix more compiler warnings. (check-in: 1b85442b user: drh 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) | |
| 08:31 | • Ticket [f8a7060e] Incorrect result for query that uses MIN() and a CAST on rowid status still Open with 3 other changes (artifact: 64317f51 user: dan) | |

| 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) | |

| 23:28 | • Fixed ticket [0a5e2c1d]: Unexpected affinity conversion for view column in IN operator plus 6 other changes (artifact: d65bc0de user: drh) | |
| 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 clearing of posix advisory locks. (check-in: 509c1ba2 user: drh tags: trunk) | |
| 20:43 | • New ticket [0a5e2c1d] Unexpected affinity conversion for view column in IN operator. (artifact: 4bce8b02 user: mrigger) | |
| 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) | |
| 17:05 | • Fixed ticket [9f66f887]: EXPLAIN PRAGMA executes PRAGMA plus 8 other changes (artifact: f8525f61 user: drh) | |
| 15:33 | • Fixed ticket [61c85385]: Row is not fetched in SELECT from VIEW plus 6 other changes (artifact: 505de8a7 user: drh) | |
| 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) | |

| 23:31 | • Edit [e15a0977ddfad3d0|e15a0977]: Move to branch pending. Edit check-in comment. (artifact: 37715ac2 user: drh) | |
| 21:56 | • New ticket [9f66f887] EXPLAIN PRAGMA executes PRAGMA. (artifact: 6c982a95 user: mrigger) | |
| 21:04 | • Edit [470ac8d50ce2f7cc|470ac8d5]: Mark "Closed". (artifact: 8029b648 user: drh) | |
| 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) | |
| 20:41 | • Ticket [d52a29a9] Unexpected affinity conversion in view status still Fixed with 4 other changes (artifact: 7c070101 user: drh) | |
| 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) | |
| 15:09 | • New ticket [61c85385] Row is not fetched in SELECT from VIEW. (artifact: 82f66d84 user: mrigger) | |
| 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) | |
| 13:06 | • Fixed ticket [d52a29a9]: Unexpected affinity conversion in view plus 8 other changes (artifact: ac513e2e user: drh) | |
| 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) | |
| 11:27 | • New ticket [d52a29a9] Unexpected affinity conversion in view. (artifact: c86e9f56 user: mrigger) | |
