19:56
New test case that still hits an assertion fault, just to prove that the previous checkin merely made the problem more obscure and did not completely fix it. check-in: a9a3b532 user: drh tags: ticket-f09fcd17810f
19:15
Simplify the query flattener so that it does not duplicate the WHERE clause of subquery that is being incorporated into the outer query - copies it directly. This is more efficient. And it also fixes the specific test case show for ticket [f09fcd17810f65f71789525] but it does not resolve the more general problem that sqlite3ExprDup() does not correctly duplicate expressions that contain subqueries with window functions. check-in: f1b18d44 user: drh tags: ticket-f09fcd17810f
17:06
When masking bits off of sqlite3.flags, make sure the mask is 64 bits in size so as not to accidentally mask of high-order bits. check-in: 53d3b169 user: drh tags: trunk
16:50
When saving off the value of sqlite3.flags, take care to preserve all 64 bits. check-in: 9c6dbcfa user: drh tags: trunk
16:11
Issue a warning whenever a double-quoted string literal is used. check-in: ac9ad504 user: drh tags: trunk
03:59
Invoking the sqlite3_trace() or sqlite3_trace_v2() interfaces cancels any sqlite3_profile() that is running. check-in: ec63d350 user: drh tags: trunk
02:01
Remove the unused pColHash field from the Table object. check-in: 3a2c0479 user: drh tags: trunk
01:53
Fix a potential NULL pointer dereference that can occur in ALTER TABLE following an OOM. Test case in TH3. check-in: ea50815b user: drh tags: trunk
01:08
Fix a missing mutex in the sqlite3_normalized_sql() interface when it is called on a prepared statement that did not previously have a computed normalization of the input SQL. check-in: 1a1a59c6 user: drh tags: trunk
2018-12-05
23:56
Get rid of the hash table used to track IN operators in the sqlite3_normalized_sql() implementation. Use simple integer variables instead. check-in: 272dc74f user: drh tags: trunk
23:45
The sqlite3_normalized_sql() interface should not be transforming quoted identifier names into wildcards. Fix this, and at the same time simplify the code substantially. check-in: e8540377 user: drh tags: trunk
21:55
Fix an imbalanced lock problem in sqlite3Normalize() introduced by the simplification in [94ea6379178e3ff6a]. check-in: f6962437 user: drh tags: trunk
19:42
Increase the version number to 3.27.0 for the next development cycle. check-in: 8f8d6828 user: drh tags: trunk

Ensure that ALTER TABLE modifies table and column names embedded in WITH clauses that are part of views and triggers. check-in: f44bc7a8 user: dan tags: trunk
13:39
Enhance the sqlite3_normalize_sql() interface so that it works even if the prepared statement was not initially compiled using SQLITE_PREPARE_NORMALIZED. Enhance the ".trace" command in the CLI so that it is able to access the full scope of functionality provided by sqlite3_trace_v2() and in particular so that it is able to show normalized SQL output using the newly enhanced sqlite3_normalize_sql() interface. check-in: 7da617e9 user: drh tags: trunk
2018-12-04
16:51
Add the "index_usage" utility program. check-in: df954552 user: drh tags: trunk

Add a simple test case for Lemon. Always include assert.h in the Lemon-generated parser. check-in: 9c9c46dc user: drh tags: trunk
14:03
Fix to the error handling logic in the Lemon parser template. This does not affect SQLite since SQLite does not use that part of the Lemon parser template. check-in: c6dfc59e user: drh tags: trunk

17:46
Make the winTruncate() method of the windows VFS be a no-op if there are outstanding references to the memory-mapped pages. Otherwise, memory might be deleted out from under those references when the file is remapped during the truncate operation. check-in: ffce4aac user: drh tags: trunk

2018-11-20

14:36
In order to avoid exporting a symbol, use a macro instead of a function to replace sqlite3_complete() in the shell code when SQLITE_OMIT_COMPLETE is defined. check-in: d584a0cb user: dan tags: trunk
13:56
Enhance the xBestIndex interface of virtual table so that if the xBestIndex method returns SQLITE_CONSTRAINT then that particular combination of constraints is considered unusable and does not participate further in query planning. check-in: 684013ce user: drh tags: trunk
13:06
Fix comments and make magic numbers into #defines in the fsdir implementation. check-in: c537c9c3 user: drh tags: trunk

20:04
When a table is renamed using "ALTER TABLE RENAME TO", update any REFERENCES clauses that refer to the table, unless "PRAGMA legacy_alter_table" is true and "PRAGMA foreign_keys" is set to false (i.e. so that when "PRAGMA legacy_alter_table" is set behaviour is still compatible with versions 3.24 and earlier). check-in: ae9638e9 user: dan tags: trunk
14:17
Fix for ticket [787fa716be3a7f650cac] check-in: 531eca61 user: drh tags: trunk

Merge the permutations fix from trunk. check-in: b753d849 user: drh tags: read-only-shadow

2018-11-06
20:08
Update the changesetfuzz program to fuzz changeset schemas as well as data. check-in: 141a93c8 user: dan tags: changesetfuzz
19:26
Enable DEFENSIVE mode by default for tests. This requires lots of case of turning DEFENSIVE off in order to dodgy things to the database for testing purposes. No all of those cases are yet handled, so "make test" does not run to completion. check-in: a1d6c671 user: drh tags: read-only-shadow
15:57
Turn on defensive mode for running test scripts. Does not yet work. check-in: 1c1d24ed user: drh tags: read-only-shadow
14:03
Only allow shadow table to be written from within a recursive SQL call. Omit the SQLITE_PREPARE_SHADOW flag. Some tests are failing because the tests depend on being able to write to shadow tables. check-in: d890c658 user: drh tags: read-only-shadow
13:37
Add enforcement of read-only on shadow tables. This does not currently work since some virtual tables are attempting to update shadow tables using sqlite3_exec(). check-in: f79b47c9 user: drh tags: read-only-shadow
2018-11-05
23:01
Initial code to make shadow tables read-only to ordinary SQL. The now xShadowName method is added to the sqlite3_module object and is used to identify potential shadow tables. The SQLITE_PREPARE_SHADOW argument to sqlite3_prepare_v3() is defined. It is designed to permit writing to shadow tables, but is currently an unused placeholder. check-in: 31942b3d user: drh tags: read-only-shadow
