14:40
Revise the layout of filenames in the Pager object so that it is unchanged from prior versions. It turns out that some important 3rd-party software does questionable pointer manipulations on those filenames that depend on that legacy layout.

Allow non-deterministic function in CHECK constraints. It turns out that PostgreSQL, MySQL, and SQLServer all allow this. We should not be the the exception. Ticket [830277d9db6c3ba1] (check-in: 8c8ce526 user: drh tags: trunk)
19:58
Fix a couple of test case issues on this branch. (check-in: 9830a44b user: dan tags: reuse-schema)
19:46

19:07
Disable a redundant test case that uses a very large stack, and hence is unable to run with -fsanitize=undefined,address. (check-in: 3c63f68e user: drh tags: trunk)

23:27
Fix a typo in a comment. No code changes. (check-in: 4363f69c user: drh tags: trunk)
21:12
The compress() function should not be deterministic since the same input can have multiple possible compressed outputs. The uncompress() function, on the other hand, is deterministic. (check-in: 84f31490 user: drh tags: trunk)
19:14
Fix #ifdefs so it compiles cleanly with all SQLITE_OMIT compile-time options. Update compile-time option testing. (check-in: 7584e4b6 user: drh tags: trunk)

Do not allow shadow tables to be dropped in defensive mode. (check-in: ad1f760f user: drh tags: branch-3.28)
14:30
Import the 3.31.0-beta FTS3/4 code directly into the 3.28 branch, thus providing 3.28 with all the latest 3.31 fixes. FTS3 has not been enhanced to use any core functionality that was not already available in 3.23, so no modifications were made to FTS3 sources for this import. (check-in: be4269c6 user: drh tags: branch-3.28)
14:18
Import all FTS3/4 enhancements and fixes that exist on the latest trunk (3.31.0-beta) that do not require extensive change to the SQLite core into the 3.22 branch. Basically, the 3.31.0 FTS3 sources are copied into 3.22.0, with minor changes to work around core enhancements that are not available in 3.22.0. (Leaf check-in: cbcbb1e5 user: drh tags: branch-3.22)
11:18
Fix a case in "fuzz.test" that could fail, as non-deterministic functions may no longer appear in CHECK constraints. (check-in: a370871e user: dan tags: trunk)
2020-01-16
17:53
New testcase() macros in select.c, for coverage of the change from two check-ins ago. (check-in: 52206488 user: drh tags: trunk)

16:12
Do not allow the constant-propagation optimization to apple to ON/USING clause terms as it does not help and it might cause downstream problems. (check-in: 1bc783da user: drh tags: trunk)
13:02
Very small performance improvement by ensuring that the argument to sqlite3VdbeFreeCursor() is non-NULL. Hold for the next sprint. (Leaf check-in: f8801ffd user: drh tags: close-cursor-faster)
12:25
Fix an SQL syntax error in the comment on the omit-left-join optimization. No changes to code. (check-in: 86b5e5a2 user: drh tags: trunk)
