50 check-ins occurring around 05a9d129254e01a5.

2018-09-19
17:24
Fix an issue in virtual table handling associated with the new Expr.x.pRight field. (check-in: 8487f84af0 user: drh tags: expr-simplify)
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: 221f3f572e 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: e4129cd3a0 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: 2034fa8089 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: 147c61a6d4 user: drh tags: expr-simplify)
11:59
Make sure temporary Expr objects are fully initialized prior to sending them into sqlite3ExprCodeTemp(). (check-in: de02a1d97a 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: 8849a463d6 user: drh tags: expr-simplify)
20:20
Version 3.25.1 (check-in: 2ac9003de4 user: drh tags: release, version-3.25.1, branch-3.25)
19:40
Fix a problem building on Android with SQLITE_ENABLE_BATCH_ATOMIC_WRITE set. (check-in: e41e50fe74 user: dan tags: trunk)
18:08
Merge all recent trunk enhancements. (check-in: 655f065404 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: e461cb2819 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: de2e3cbd08 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: 3e1a2f6614 user: dan tags: trunk)
2018-09-17
20:47
Further optimizations to the UPDATE logic to avoid making changes to partial indexes if none of the columns mentioned in the WHERE clause are modified by the UPDATE. (check-in: d1365a5bf0 user: drh tags: trunk)
15:25
Disable the ORDER BY LIMIT optimization in queries using window functions. This fixes a problem that was introduced by check-in [206720129ed2fa8875a286] which attempted to fix ticket [9936b2fa443fec03ff25f9]. This changes is a fix for the follow-in tocket [510cde277783b5fb5de628]. (check-in: 36c75fd5b7 user: drh tags: branch-3.25)

Fix a false-positive in the post-ALTER-TABLE schema verification logic that prevents ALTER TABLE from working if the table being altered has a trigger that references any column of a virtual table. Ticket [b41031ea2b537237]. (check-in: 5ce568c0e7 user: drh tags: branch-3.25)
14:13

2018-09-11
19:05
