| 16:41 | Fix a problem in the fts3 integrity-check routine causing it to report as corrupt tables that contain values with embedded 0x00 bytes. Ticket [278ac142625e3dcd] (check-in: 629e20c9 user: dan tags: trunk) | |

|
2019-10-05
| ||
| 19:53 | Omit the check for conflicting shared-cache locks in sqlite3Prepare() if the database connection uses no shared cache. We might be able to go back and remove this code completely, due to the newer Schema.iGeneration logic, but that will take more analysis.

|
2019-10-03

| 16:02 | Avoid running a couple of tests in affinity2.test as part of the valgrind permutations, as the way floating point computations are simulated by valgrind causes them to fail. (check-in: 7f9a4b60 user: dan tags: trunk) | |
| 14:51 | Increase the precision of floating point value display in VDBE debugging output. No changes to normally deployed code. (check-in: a561a656 user: drh tags: trunk) | |

| ||
| 12:38 | Omit the sqlite3IntTokens array constant for a code simplification. (check-in: f907395e user: drh tags: trunk) | |
| 11:55 | When a scalar subquery has a pre-existing "LIMIT X" then change it to "LIMIT X<>0" rather than just "LIMIT 1" so that if X is 0 the limit will still be zero. Ticket [99cd4807dc03f178]. Test cases in TH3. (check-in: 82e5dcf5 user: drh tags: trunk) | |

| 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) | |
|

| 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) | |
| 20:26 | 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) | |

| 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) | |

| 16:37 | Fix a problem with queries of the form "SELECT min(<expr>) ... WHERE <expr>=?" where there is an index on <expr>. Fix for [71e183ca]. (check-in: d465c3ee 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) | |

| 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) | |
