Clarify some malloc size computations to simplify the proof that they are safe. Remove some code associated with cygwin that is marked "#if 0".

год назад

Back out the "low-quality index" query planner hack of check-in [bcac937526d9a6ef]. Subsequent query planner enhancements for dealing with star-queries make that change unnecessary and the change was recently found to cause a performance regression in an unrelated query. Also fix a typo in a debugging message.

Tamp down various harmless compiler warnings. Use "int" in places instead of "u16" or "i16" since the compiler complains less and generates faster code.

Fix an off-by-one error in an assert(), discovered by oss-fuzz. This is a harmless error in as much as assert()s are disabled in production builds, and because the off-by-one only occurs on nonsensical CREATE INDEX statements.

год назад

The FuncDev.nArg field values -3 and -4 now have special meansing of 1 or more or 2 or more arguments, respectively. This saves space in the built-in function table, resulting in slightly faster performance and a reduced binary size.

Fix a problem in the sqlite_dbpage() table-valued function when it is trying to truncate a file in locking-mode=EXCLUSIVE and the file was obtained via sqlite3_deserialize(). Problem found by dbsqlfuzz.

Add the SQLITE_INDEX_SCAN_HEX bit to the sqlite3_index_info.idxFlags bitmask. When set, this bit causes the EXPLAIN QUERY PLAN output to show the idxNum value in hex rather than in decimal. This is purely a debugging aid.

Fix a bug in the NOT NULL/IS NULL optimization of check-in [cb94350185f555c3] that can cause invalid data to be used for a column if that column has a CHECK constraint that includes the NOT NULL or IS NULL operator. Problem discovered by the [https://issues.chromium.org/issues/415397143|Chromium fuzzer]. Never seen in the wild, as far as anybody knows.

Ensure that the database encoding is detected before the code generator gets too far down into byte-code generation and execution, but not so early that it interferes with initialization. [forum:/forumpost/bc75a4d20b756044|Forum thread bc75a4d20b756044].

Fix PRAGMA trusted_schema=OFF and similar so that it restricts the kinds of functions in CHECK constraints that the documentation says it does. It was letting through some function that it ought not have. This is a defect in [5720924cb07766cd]. See [forum:/forumpost/3fa9d44c0b381342|forum thread 2025-05-08T08:50Z].

The number of declared columns in an index is limited to SQLITE_LIMIT_COLUMN. But the actual number of columns in the implementation might need to be twice as much to account for the primary key at the end. Ensure that the code is able to deal with this. This is a correction to check-in [d7729dbbf231d57c].

год назад

Detect when a UNIQUE or PRIMARY KEY on a WITHOUT ROWID table would need to use more than SQLITE_LIMIT_COLUMN columns and raise an error. Also include some unrelated compiler warning fixes.

The win32lock and win32longpath tests don't work on Cygwin

Test app/script patches from Jan Nijtmans for cygwin. Add/replace many more sentinel arguments for TCL variadic functions which specifically need a NULL trailing argument. With this, 'make test' on cygwin runs to completion for me, with 134 of 329227 tests failing. MSC build fails the same 13 tests which fail for me in trunk.
