2019-08-23
20:33

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

13:32
Invert the meaning of the regBignull flag so that it is 1 when doing the normal scan and 1 when scanning nulls.

15:47
Do not pass ORDER BY clauses with non-standard NULL handling to virtual table implementations. check-in: a9a82ee8 user: dan tags: nulls-last
14:43

13:49
Add the new sqlite3_drop_modules() interface to the loadable extension mechanism. check-in: 658bd516 user: drh tags: trunk

19:13
When populating an ephemeral b-tree for the RHS of an IN(...) clause, avoid applying an affinity to a value that may be used later on for some other purpose. Fix for [c7a117190]. check-in: 43e8b143 user: dan tags: trunk
18:16

15:47
Merge trunk changes into this branch. check-in: db1e6080 user: dan tags: nulls-last
15:27
Activate introspection pragmas by default. The new option SQLITE_OMIT_INTROSPECTION_PRAGMAS must be provided to keep them out. check-in: 9c4bca64 user: drh tags: trunk
00:53
The SQLITE_DIRECTONLY flag, when added to sqlite3_create_function() prevents the function from being used inside a trigger or view. check-in: de767376 user: drh tags: trunk

23:11
Fix harmless compiler warnings in the TCL interface. check-in: f17e7229 user: drh tags: trunk
21:27
Add the SQLITE_DBCONFIG_ENABLE_VIEW option, together with a "db config" command in the TCL interface that can access that option as well as all the other sqlite3_db_config() boolean options. check-in: 61b4bccd user: drh tags: trunk
20:04
Provide the SQLITE_DIRECTONLY flag for app-defined functions that prohibits the use of those functions within triggers or views. Closed-Leaf check-in: fc745845 user: drh tags: directonly
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: 98357d8c 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: 4f5b2d93 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: b2e79f8f user: drh tags: trunk
13:17
Ensure that the cell overwrite optimization does not overwrite the header of the b-tree page. check-in: 4cc5694c 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: b517a52f 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: 4d41ca7d user: drh tags: trunk

15:22
Merge latest trunk changes with this branch. Leaf check-in: 5b4689d8 user: dan tags: reuse-schema
15:11

2019-08-12
18:26
Make sure the btree cursor overflow cache is cleared when overwriting a cell in sqlite3BtreeInsert(). Ticket [3cf9bb227e9a5d32] check-in: 7dae7b96 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: 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
15:19
Make the sha3 extension part of the amalgamation, enabled using SQLITE_ENABLE_SHA3. check-in: a48a7b78 user: drh tags: sha3
14:17

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: 724f4df9 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: da01ba4f user: drh tags: trunk
14:35
Add extra test cases related to the previous commit. check-in: 3c690b2b user: dan tags: trunk
14:16

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: eaf15d9b user: drh tags: trunk

In shared-schema mode, handle the case where a connection has created a virtual-table object, but is later assigned a different shared-schema object for which the virtual-table schema has not yet been initialized. check-in: e30c7414 user: dan tags: reuse-schema
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
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
