2018-10-01
14:05
Fix a potential crash that can occur while reading an index from a corrupt database file. The corruption is a record-header-size that is larger than 0x7fffffff. Problem detected by OSSFuzz against GDAL and reported to us (with a suggested fix) by Even Rouault. The test case is in TH3. Leaf check-in: 5d291658 user: drh tags: branch-3.25
11:00
Ensure that the OP_VColumn opcode does set sqlite3_vtab_nochange() unless the OPFLAG_NOCHNG bit is set in P5. Fix for ticket [69d642332d25aa3b7315a6d385] check-in: 31ac8dba user: drh tags: branch-3.25
2018-09-29
19:38
Add the PRAGMA table_vinfo command (with an extra "v" before "info") that works like PRAGMA table_info (without the "v") except that it also shows hidden columns on virtual tables. check-in: 8bcd1a59 user: drh tags: pragma-table-vinfo
2018-09-27
13:10
Disallow the use of window functions in the recursive part of a recursive CTE. Fix for ticket [e8275b415a2f03bee]. check-in: b2849570 user: drh tags: branch-3.25
2018-09-25

20:48
Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. check-in: 31dc8b19 user: drh tags: branch-3.25
19:41
Allow a writable virtual table to have a schema with an INTEGER PRIMARY KEY and WITHOUT ROWID. This fixes ticket [f25d5ceebe1d710ff61a571e395356869d8272ef]. Test case in TH3. check-in: 3139af99 user: drh tags: branch-3.25

14:10
Allow a writable virtual table to have a schema with an INTEGER PRIMARY KEY and WITHOUT ROWID. This fixes ticket [f25d5ceebe1d710ff61a571e395356869d8272ef]. Test case in TH3. check-in: 5a38d928 user: drh tags: trunk
12:37
Use compile-time options SQLITE_QUERY_PLANNER_LIMIT and SQLITE_QUERY_PLANNER_LIMIT_INCR to control the value for WhereLoopBuilder.iPlanLimit, rather than embedding magic numbers in the code. check-in: 903e5018 user: drh tags: trunk
10:47
Increase the initial value of WhereLoopBuilder.iPlanLimit to 20K. Issue a warning if the iPlanLimit reaches zero. check-in: 3dd35f51 user: drh tags: trunk
2018-09-23
02:01

23:41
Fix harmless compiler warning when compiled with SQLITE_OMIT_AUTHORIZATION. check-in: 50f2fa19 user: mistachkin tags: trunk
19:06
Comment typo fixed. No code changes. check-in: 7e68cdab user: drh tags: trunk
18:43
Put a limit counter on the query planner that restricts the number of index+constraint options that can be considered for each table in a join. This prevents certain pathological queries from taking up too much time in the query planner. check-in: 8690b5a0 user: drh tags: trunk
13:07
Optimization to the OP_MakeRecord opcode makes speed-check.sh run about 1.1 million cycles faster, and results in a slightly smaller library. check-in: d10e6362 user: drh tags: trunk
2018-09-20
20:43
Minor code simplification. check-in: 22ae8a52 user: drh tags: trunk
20:15
Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. check-in: 7edd26ed user: drh tags: trunk
19:02
Combine the Expr.pTab and Expr.pWin fields into a union named "y". Add a new EP_WinFunc property that is only true if Expr.y.pWin is a valid pointer. This reduces the size of the Expr object by 8 bytes, reduces the overall amount of code, and shaves over 1 million cycles off of the speed test. check-in: ad130bb8 user: drh tags: trunk
17:21
By default, make all "ALTER TABLE RENAME" statements executed within a virtual table xRename() method exhibit the legacy behaviour. Closed-Leaf check-in: 71947337 user: dan tags: legacy-alter-table
08:28
Add a PRAGMA that restores the legacy ALTER TABLE RENAME TO behaviour. check-in: 5acad2e9 user: dan tags: legacy-alter-table
2018-09-19
20:14
Reduce the size of Expr to 64-bytes. This works somewhat, but there are test failures. More importantly, the size reduction from 80- to 64-bytes has not lowered the schema memory usage, but it has made the code a little bigger and a little slower. So the initial evidence is that this Expr refactoring experiment is not working... Leaf check-in: 24b0f66a user: drh tags: expr-simplify
18:17
A minor code simplification, saved in a branch for future reference. Leaf check-in: 5e458f4a user: drh tags: minor-altertab-simplification
17:24

17:09
Fix a compilation issue in the "userauth" extension. Also fix a few test script errors that occur with SQLITE_USER_AUTHENTICATION=1 builds. check-in: 221f3f57 user: dan tags: trunk
16:35
Make sure Expr.eX changes back to EX_None after Expr.x.pRight is set to NULL due to an OOM. check-in: e4129cd3 user: drh tags: expr-simplify
15:08
Fix the "sqlite3" command in the TCL interface so that it correctly returns an error if invoked with no arguments. check-in: 2034fa80 user: drh tags: trunk
14:54
Reduce the size of Expr from 80 to 72 bytes moving the pRight field inside the "x" union. This is an incremental check-in that still has issues. check-in: 147c61a6 user: drh tags: expr-simplify
11:59
Make sure temporary Expr objects are fully initialized prior to sending them into sqlite3ExprCodeTemp(). check-in: de02a1d9 user: drh tags: expr-simplify
2018-09-18
21:35
In the Expr object, the Expr.eX field determines what value is stored in the Expr.x union. This mostly works, but there are issues identified by valgrind. check-in: 8849a463 user: drh tags: expr-simplify
20:20
Version 3.25.1 check-in: 2ac9003d user: drh tags: release, branch-3.25, version-3.25.1
19:40

18:08
Merge all recent trunk enhancements. check-in: 655f0654 user: drh tags: expr-simplify
17:50
Avoid incrementing the SQLITE_LOOKASIDE_MISS_SIZE stat before sqlite3_open() returns. Fix test script problem in lookaside.test. check-in: e461cb28 user: dan tags: trunk
17:00
Enhance tester.tcl so that when "--malloctrace=1" is specified, the test generates self-contained Tcl scripts that present GUIs instead of *.sql files that require a separate program to interpret. check-in: de2e3cbd user: dan tags: trunk
16:06
Minor improvements to the permutations.test script. Most notably, a command like "permutations.test alter%" now runs all test scripts with names that match the LIKE pattern "alter%". Or, say, "permutations wal alter%" to run all alter% tests in wal mode. check-in: 3e1a2f66 user: dan tags: trunk
2018-09-17
20:47

Add the new "explain" virtual table in ext/misc. Use this virtual table for additional test cases for the optimization that avoids updating indexes on expressions when none of the columns changed by the UPDATE are in the expression. check-in: 2404304c user: drh tags: trunk
