2020-01-17
15:33

14:56
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.

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)
2019-12-19

2019-12-03
03:31
Avoid a harmless zero offset of a null pointer in FTS3, so as to not provoke unnecessary warnings from run-time checkers. (check-in: 85d95abe user: drh tags: trunk)
02:51
Avoid computing a zero offset of a null pointer, which though this is technically harmless, is upsetting to pedantic run-time checkers. (check-in: 3ce804e9 user: drh tags: trunk)
2019-11-30
19:29
Do not allow a term in the WHERE clause of the query to qualify a partial index on the right table of a LEFT JOIN. Ticket [7f39060a24b47353] (check-in: 4066a34d user: drh tags: trunk)

11:49
Fix a harmless compiler warning. (check-in: 34343c4b user: drh tags: trunk)

00:42
Revise the SQLITE_OPEN_NOFOLLOW so that it actually uses O_NOFOLLOW in the open() system call. This backs out the SQLITE_ACCESS_SYMLINK value but adds the new SQLITE_OK_SYMLINK return code from the xFullPathname method of sqlite3_vfs when that routine resolves symbolic links. O_NOFOLLOW is always included in open() system calls for journal files. (check-in: 6a64fb6a user: drh tags: trunk)

Ensure all file names passed to the VFS layer are double-zero terminated. (check-in: 251230cf user: mistachkin tags: trunk)
18:43
In the SQLITE_OPEN_NOFOLLOW processing, distinguish between an I/O error on the xAccess() call and an actual symlink encounter. (check-in: 2e98b42f user: drh tags: trunk)

2019-11-11
15:13

2019-11-10
11:09
Proper surrogate pair decoding added to JSON functions. See the mailing list bug report and https://bugs.python.org/issue38749. More test cases needed here, but it seems to work so far. (check-in: 51027f08 user: drh tags: trunk)

2019-11-03
00:07
The optimization of check-in [9b2879629c34fc0a] is incorrectly reasoned. The WHERE clause of the partial index might not be true if the table of the partial index is the right table of a left join.

13:32
In sqlite3GenerateIndexKey(), do not attempt to reuse column values from the previous index if the current index is a partial index as the partial index test may have changed those values. Ticket [a9efb42811fa41ee] (check-in: 17e9f658 user: drh tags: trunk)

13:16
Ignore differences in Expr.op2 in sqlite3ExprCompare() in cases where it does not matter. Ticket [1d2a8efc6c3a595a]. (check-in: 32982067 user: drh tags: trunk)
12:30
Enhance the TreeView logic to show information about Expr.op2 for FUNCTION and COLUMN nodes. (check-in: aceeaf9e user: drh tags: trunk)
2019-10-30

16:29
Simplify the bytecode generation for SQL function calls such that the OP_Function or OP_PureFunc opcodes are coded directly, rather than using the intermediate OP_Function0 or OP_PureFunc0 - opcodes that are now removed. (check-in: 84e02d77 user: drh tags: trunk)
13:00

03:39
Tighten the generated column requirement such that every table must have at least one non-generated column. Ticket [166347c6fc994155]. (check-in: 4fba090e user: drh tags: trunk)
03:30
Add a missing translation from table column numbers to storage table numbers while processing constraints on an UPDATE statement. Ticket [9621dd78a024d07a] (check-in: 361ea81a user: drh tags: trunk)

2019-10-26
23:51
Remove code from the constraint checker that generates virtual column values with the incorrect time. Turns out the the regular code for all other columns works correctly and so the incorrect special-case code is not actually needed. Fix for ticket [3ea175512444b0d1]. (check-in: 5b4c0f2d user: drh tags: trunk)
18:56
Remove redundant code resulting from a merge error on the previous check-in. (check-in: 713fe86b user: drh tags: trunk)
