14:35
Ensure that the optional "sz=N" parameter that can be manually added to the end of an sqlite_stat1 entry does not have an N value that is too small. Ticket [e4598ecbdd18bd82] check-in: 98357d8c12 user: drh tags: trunk
13:53
Ensure that SQLite does not attempt to process incompatible window functions in a single scan. Fix for [256741a1]. check-in: 4f5b2d9381 user: dan tags: trunk
13:46
Avoid downgrading SQLITE_CORRUPT errors detected by the schema parser into SQLITE_NOMEM or SQLITE_ERROR errors. check-in: b2e79f8ff0 user: drh tags: trunk
13:17
Ensure that the cell overwrite optimization does not overwrite the header of the b-tree page. check-in: 4cc5694cbd user: drh tags: trunk
00:04
Early detection out-of-bounds page numbers on the direct-overflow-read optimization gives consistent error messages regardless of whether or not the optimization is enabled. check-in: b517a52fa3 user: drh tags: trunk
2019-08-14
15:17
Always check for reads past the end of the file on the in-memory journal driver. This used to be an assert(). check-in: 4d41ca7d6e user: drh tags: trunk
2019-08-13
20:34
Add some static to the 'regexp' extension. check-in: a21d1dde73 user: mistachkin tags: trunk
17:56
Update test cases so that they work with ICU enabled. check-in: 408144a183 user: dan tags: trunk
17:27
Update some corruption test cases to take [724f4df9c] into account. check-in: 927cd7b4c5 user: dan tags: trunk
15:22
Merge latest trunk changes with this branch. check-in: 5b4689d89c user: dan tags: reuse-schema
15:11
Fix a problem with RBU function sqlite3rbu_bp_progress() when used during an RBU vacuum. check-in: 8c44b02f14 user: dan tags: trunk
2019-08-12
18:26
Make sure the btree cursor overflow cache is cleared when overwriting a cell in sqlite3BtreeInsert(). Ticket [3cf9bb227e9a5d32] check-in: 7dae7b969e user: drh tags: trunk
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: 07babb0f89 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: 636ca4472c user: drh tags: trunk
15:37
Fix the build for compilation using separate files rather than the amalgamation. Leaf check-in: 1e0f4869de user: drh tags: sha3
15:19
Make the sha3 extension part of the amalgamation, enabled using SQLITE_ENABLE_SHA3. check-in: a48a7b7859 user: drh tags: sha3
14:17
Add a TESTCTRL that disables the verification of type, name, and tbl_name in the sqlite_master table. check-in: 48d9b48ab4 user: drh tags: trunk
00:08
Validate the type, name, and tbl_name fields of the sqlite_master table when loading the schema, unless writable_schema is engaged. check-in: 724f4df9cc user: drh tags: trunk
2019-08-10
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: da01ba4fa4 user: drh tags: trunk
14:35
Add extra test cases related to the previous commit. check-in: 3c690b2b05 user: dan tags: trunk
14:16
Remove two incorrect assert() statements from the logic used to derive column names and types from subqueries. check-in: 712e477148 user: drh tags: trunk
2019-08-09
20:26
Allow the RHS of a row-value IN operator to use a compound query with an ORDER BY clause. check-in: eaf15d9bae user: drh tags: trunk
01:59
Modify signature of sqlite3VdbeChangeOpcode() to accept int instead of u32. check-in: 68b7f2acf4 user: mistachkin tags: trunk
01:11
Fix more compiler warnings. check-in: 1b85442b61 user: drh tags: trunk
2019-08-08
19:40
Fix harmless compiler warnings. check-in: 1eef4ddea9 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: f1cd234c98 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: 83450d1070 user: drh tags: trunk
16:23
More legacy STAT3 code removed. Closed-Leaf check-in: 845d2f17de user: drh tags: omit-stat3
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: 1e17ea2fd1 user: drh tags: omit-stat3
01:39
Remove a NEVER() that is reachable from a corrupt database. check-in: 30e6ee27a9 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: 7f2246a17b 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: f5d0436d8d user: dan tags: trunk
17:45
Eliminate some more cases of redundant sorting in window-function queries. check-in: 8158d2aca6 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: 193c87fc96 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: 17b3d2218c 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: 509c1ba26a user: drh tags: trunk
20:26
Enhance the ".recover" output in the shell to use double-quotes around table and column identifiers. check-in: 846d2d2d2f 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: bfc29e62ef 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: 9c8c1092a8 user: drh tags: trunk
15:18
Performance optimization to the new affinity handling logic. Closed-Leaf check-in: c9724e761b user: drh tags: pending
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: e8234f6939 user: drh tags: pending
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: e15a0977dd user: dan tags: pending
20:45
Add test cases to this branch. Closed-Leaf check-in: f37317d81c 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: 7480db307c 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: 470ac8d50c 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 [https://www.sqlite.org/docsrc/info/07b7749da88d54e5|[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: 09cd0c0c6e 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: a29f2a7d07 user: drh tags: trunk
16:22
Improved detection of corruption on the freeblock list of a btree page. check-in: 4b00799bdf 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: 2ac0e42f8a 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: b6d52c9364 user: dan tags: trunk
2019-08-03
19:06
Strengthen an assert() in the WHERE clause code generator for the min/max optimization. check-in: 1bd4b97d64 user: drh 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: d465c3eef4 user: dan tags: trunk
16:17
In the ".wheretrace 0x100" debugging mode, show the structure of the main parameters to sqlite3WhereBegin() calls. check-in: fd598e475d 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: 2660e9292a 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: 49aa344806 user: drh tags: prng-seed-test-control
2019-08-02
21:03
Fixes to the PRNG_SEED pragma idea. check-in: c71098409c user: drh tags: prng-seed-test-control
20:45
Add the SQLITE_TESTCTRL_PRNG_SEED test control. check-in: 3ac5723164 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: faaaae4940 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: a7277ed062 user: dan tags: tkt-41866dc37
2019-08-01
22:48
The sqlite3_set_authorizer() interface should only expire prepared statements when it is setting a new authorizer, not when clearing the authorizer. And statements that are running when sqlite3_set_authorizer() is invoked should be allowed to continue running to completion. check-in: 961e2f08c3 user: drh tags: trunk
15:18
Add new release tests for windows to releasetest_data.tcl. check-in: 1b330ec24c user: dan tags: trunk

2019-07-31
21:08
Update "releasetest_data.tcl" so that it is a standalone script that generates sh or batch scripts to run each tcl test run at release time. Update wapptest.tcl to use it. check-in: 559c2dd672 user: dan tags: trunk
15:16
New test cases in test/fuzzdata8.db. check-in: 6e92d71c24 user: drh tags: trunk
12:13

2019-07-30
21:00
Fix the build for when -DSQLITE_SMALL_STACK is used. check-in: b9eda2249a 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: 89bf0399e8 user: drh tags: trunk
01:17
Disable the skip-scan optimization for DISTINCT queries. Fix for ticket [ced41c7c7d6b4d36] check-in: a871d69c6d user: drh tags: trunk

15:32
When using an index for both DISTINCT and ORDER BY, do not confuse the number of columns required for distinctness with the number required to get the correct sort order. Fix for [6749cb3c]. check-in: 6ac0f82245 user: dan tags: trunk
14:42
When using an index for both DISTINCT and ORDER BY, do not confuse the number of columns required for distinctness with the number required to get the correct sort order. Fix for [6749cb3c]. Closed-Leaf check-in: b47169319a user: dan tags: tkt-6749cb3c
06:06
Fix the OP_Affinity operator so that when applying REAL affinity, it only sets MEM_IntReal if the integer value will fit in 6 bytes or less. Fix for ticket [ba2f4585cf495231] check-in: 2b221bb15f user: drh tags: trunk
05:23
Fix a minor typo in a comment. check-in: cea8a892f7 user: drh tags: trunk

19:20
Improve the ".recover" command's handling of corrupt database schemas. check-in: becaaa4d29 user: dan tags: trunk
08:15
Improve the ".recover" command in the shell tool so that it is not confused by auto-vacuum databases. And so that it can recover tables for which one or more of the column names are SQL keywords. check-in: 87d76047d6 user: dan tags: trunk
2019-07-23
13:26
Avoid redefining types u32 and u16 when fossildelta.c is compiled as part of the amalgamation. check-in: d8e88248e3 user: dan tags: trunk
