40 check-ins using file src/global.c version 0c9c4584

2019-08-12
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
Remove two incorrect assert() statements from the logic used to derive column names and types from subqueries. (check-in: 712e4771 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: eaf15d9b 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)
15:24
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)
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 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)
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)
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)
2019-08-03
19:06
Strengthen an assert() in the WHERE clause code generator for the min/max optimization. (check-in: 1bd4b97d 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: 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)
2019-08-02
21:03
Fixes to the PRNG_SEED pragma idea. (check-in: c7109840 user: drh tags: prng-seed-test-control)
20:45
Add the SQLITE_TESTCTRL_PRNG_SEED test control. (check-in: 3ac57231 user: drh tags: prng-seed-test-control)
