50 check-ins occurring around f37317d81cc2864e.

Modify signature of sqlite3VdbeChangeOpcode() to accept int instead of u32. check-in: 68b7f2acf4 user: mistachkin tags: trunk
Fix more compiler warnings. check-in: 1b85442b61 user: drh tags: trunk
Fix harmless compiler warnings. check-in: 1eef4ddea9 user: drh tags: trunk
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
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
More legacy STAT3 code removed. Closed-Leaf check-in: 845d2f17de user: drh tags: omit-stat3
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: edf45cd7c6 user: dan tags: reuse-schema
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
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: 111e2c73cf user: dan tags: reuse-schema
Remove a NEVER() that is reachable from a corrupt database. check-in: 30e6ee27a9 user: drh tags: trunk
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
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
Eliminate some more cases of redundant sorting in window-function queries. check-in: 8158d2aca6 user: dan tags: trunk
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
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
Improved reuse of file descriptors for which close() is delayed to prevent clearing of posix advisory locks. check-in: 509c1ba26a user: drh tags: trunk
Enhance the ".recover" output in the shell to use double-quotes around table and column identifiers. check-in: 846d2d2d2f user: drh tags: trunk
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
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
Performance optimization to the new affinity handling logic. Closed-Leaf check-in: c9724e761b user: drh tags: pending
Add a multi-threaded test to threadtest3.c for the feature on this branch. check-in: 62557fab0d user: dan tags: reuse-schema
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
Add an assert() to the code on this branch. check-in: fdd44bbb50 user: dan tags: reuse-schema
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
Add test cases to this branch. Closed-Leaf check-in: f37317d81c user: dan tags: tkt-61c853-A
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
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
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
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
Improved detection of corruption on the freeblock list of a btree page. check-in: 4b00799bdf user: drh tags: trunk
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
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
Strengthen an assert() in the WHERE clause code generator for the min/max optimization. check-in: 1bd4b97d64 user: drh tags: trunk
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
In the ".wheretrace 0x100" debugging mode, show the structure of the main parameters to sqlite3WhereBegin() calls. check-in: fd598e475d user: drh tags: trunk
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
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
Fixes to the PRNG_SEED pragma idea. check-in: c71098409c user: drh tags: prng-seed-test-control
Add the SQLITE_TESTCTRL_PRNG_SEED test control. check-in: 3ac5723164 user: drh tags: prng-seed-test-control
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
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
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
Add new release tests for windows to releasetest_data.tcl. check-in: 1b330ec24c user: dan tags: trunk
Fix a problem in ALTER TABLE triggered by views or triggers that include the construction "ORDER BY true" or "ORDER BY false". check-in: 8168021f9a user: dan tags: trunk
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
New test cases in test/fuzzdata8.db. check-in: 6e92d71c24 user: drh tags: trunk
Do not allow the json_set() function to overwrite the same element more than once. check-in: f237f60e4f user: drh tags: trunk
Fix the build for when -DSQLITE_SMALL_STACK is used. check-in: b9eda2249a user: drh tags: trunk
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
Disable the skip-scan optimization for DISTINCT queries. Fix for ticket [ced41c7c7d6b4d36] check-in: a871d69c6d user: drh tags: trunk
