100 check-ins occurring around 48b518eb6f76fb0b.

2019-08-09
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 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)
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)
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: faaaae49 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: a7277ed0 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: 961e2f08 user: drh tags: trunk)
15:18
Add new release tests for windows to releasetest_data.tcl. (check-in: 1b330ec2 user: dan tags: trunk)
10:58
Fix a problem in ALTER TABLE triggered by views or triggers that include the construction "ORDER BY true" or "ORDER BY false". (check-in: 8168021f 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: 559c2dd6 user: dan tags: trunk)
15:16
New test cases in test/fuzzdata8.db. (check-in: 6e92d71c user: drh tags: trunk)
12:13
Do not allow the json_set() function to overwrite the same element more than once. (check-in: f237f60e user: drh tags: trunk)
2019-07-30
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)
01:17
Disable the skip-scan optimization for DISTINCT queries. Fix for ticket [ced41c7c7d6b4d36] (check-in: a871d69c user: drh tags: trunk)
2019-07-29
17:18
Convert an assert() in R-Tree into a database corruption detection case. (check-in: 48b518eb user: drh tags: trunk)
16:53
Fix a crash in fts3 caused by corrupt database records. (check-in: 11f7f94f user: dan 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: 6ac0f822 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: b4716931 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: 2b221bb1 user: drh tags: trunk)
05:23
Fix a minor typo in a comment. (check-in: cea8a892 user: drh tags: trunk)
02:52
Sync up warning related compiler options in the Makefiles for MSVC. (check-in: e77d48d1 user: mistachkin tags: trunk)

Fix faulty asserts in the code generator. Ticket [c52b09c7f38903b1] (check-in: 01cdc590 user: drh tags: trunk)
20:10
Improve the ".recover" command so that it handles intkey pages linked into non-intkey b-trees, and vice-versa, better. (check-in: 9c458acb user: dan tags: trunk)
19:20
Improve the ".recover" command's handling of corrupt database schemas. (check-in: becaaa4d 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: 87d76047 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: d8e88248 user: dan tags: trunk)
2019-07-22
23:30
Do not use the insert-overwrite optimization if the cell might overwrite the page header. (Leaf check-in: 9991626b user: drh tags: branch-3.29)
23:24

21:12
Make sure any window definitions in an ORDER BY clause are removed from the SELECT statement if the ORDER BY clause gets optimized out. (check-in: 23b11967 user: drh tags: winfunc-in-orderby)
18:00
Early detection of a corrupt R-Tree in the R-Tree search algorithm. (check-in: 2bf5a4c1 user: drh tags: trunk)

10:31
Fix a faulty assert() in walker.c that could fail when processing an ALTER TABLE statement on a schema containing invalid table references that are part of a WINDOW definition. (check-in: ee076c28 user: dan tags: trunk)
01:25
Fix a new problem in the BETWEEN operator when applied to a window function. The problem was introduced yesterday by check-in [7ef7b23cbb1b9ace]. This cherry-pick also needed to remove an assert from sqliteExprDelete(). (check-in: ce6bf395 user: drh tags: branch-3.29)
01:11
Fix a new problem in the BETWEEN operator when applied to a window function. The problem was introduced yesterday by check-in [7ef7b23cbb1b9ace]. (check-in: 47e23064 user: drh tags: trunk)
2019-07-18
20:55

2019-07-17
19:57
Always use the stdlib.h intptr_t type for pointer-integer conversions, when it is available. (check-in: c0d93244 user: drh tags: trunk)
18:19
When processing a BETWEEN or CASE expression, avoid transforming a node of the original expression into a TK_REGISTER node. Instead, take a copy and use it instead. Fix for [1be72aab9]. (check-in: bc6b0d73 user: drh tags: branch-3.29)
18:11
Fix problems with duplicate fields in the PRIMARY KEYs of WITHOUT ROWID tables. (check-in: bda25883 user: drh tags: branch-3.29)
16:18
Fix an incorrect assert() in balance_nonroot(). (check-in: 59c9e73f user: drh tags: trunk)
15:05
Improvement to the hexdb interpreter built into the CLI and into the TCL test harness: Round the "size" up to the next multiple of the "pagesize". (check-in: 9ec92939 user: drh tags: trunk)
14:34
When processing a BETWEEN or CASE expression, avoid transforming a node of the original expression into a TK_REGISTER node. Instead, take a copy and use it instead. Fix for [1be72aab9]. (check-in: 7ef7b23c user: dan tags: trunk)
12:49
Fix the WITHOUT ROWID table logic so that it generates a correct KeyInfo object for tables that have a PRIMARY KEY containing the same column used more than once with different collating sequences. Enhance the index_xinfo pragma to assist in testing the above. Fix for ticket [fd3aec0c7e3e2998]. (check-in: 84a51a75 user: drh tags: trunk)
12:42
New test cases for PRAGMA index_xinfo on a WITHOUT ROWID table. And new testcases using index_xinfo to verify that WITHOUT ROWID tables are constructed correctly. (Closed-Leaf check-in: 340378c1 user: drh tags: wor-pk-dups)
11:01
Enhance the "PRAGMA index_info()" and "PRAGMA index_xinfo()" statements so that they allow a WITHOUT ROWID table as their argument, and in that case show the structure of the underlying index used to implement the WITHOUT ROWID table. (check-in: 62274ff6 user: drh tags: wor-pk-dups)
09:18
Fix problems with duplicate fields in the PRIMARY KEYs of WITHOUT ROWID tables. (check-in: bd9a47a3 user: dan tags: wor-pk-dups)
