Prototype implementation for the VACUUM INTO command. (check-in: 036e3320 user: drh tags: vacuum-into)

2018-12-06
22:12
Performance improvement: Avoid using sqlite3WalkerSelectExpr() and sqlite3WalkerSelectFrom() twice, so that the compiler will in-line their implementation. (Closed-Leaf check-in: 2b9258b8 user: drh tags: ticket-f09fcd17810f)
22:04
Fix the sqlite3ExprDup() routine so that it makes complete duplications of subqueries containing window functions. (check-in: 94017454 user: drh tags: ticket-f09fcd17810f)
20:26
Add the mutexfree-shmlock experiment to the begin-concurrent-pnu branch. (check-in: 3aead209 user: dan tags: begin-concurrent-pnu-mutexfree-shmlock)
20:18
Experimental changes to (optionally) allow double-quoted strings to be checked against known identifiers. (Leaf check-in: 73a6b8c1 user: mistachkin tags: normalize_v4)
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)
18:58
Experiment with using an atomic CPU primitive instead of a mutex for intra-process locking with the unix-excl VFS. (check-in: 8f4cb9dd user: dan tags: mutexfree-shmlock)
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)
03:13
Merge fixes from trunk. (check-in: f2083ee4 user: drh tags: begin-concurrent-pnu)
02:08
Merge bug fixes from trunk. (check-in: 1e13aaa2 user: drh tags: begin-concurrent)
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)
00:08
Merge ALTER TABLE and sqlite3_normalized_sql() bug fixes from trunk. (check-in: 3793e5d5 user: drh tags: begin-concurrent-pnu)
00:05
Merge ALTER TABLE and sqlite3_normalized_sql() fixes from trunk. (check-in: acf10b3f user: drh tags: begin-concurrent)
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)
23:25
Bungled checkin. Ignore. (Closed-Leaf check-in: 9b6e9a6e user: drh tags: mistake)
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)
18:28
Merge enhancements and the ALTER TABLE bug fix from trunk. (check-in: edfc2acf user: drh tags: apple-osx)
17:48
Simplifications to the sqlite3_normalized_sql() implementation. (check-in: 94ea6379 user: drh tags: trunk)
13:49
Merge enhancements from trunk, especially the sqlite3_normalized_sql() enhancement. (check-in: 342c9538 user: drh tags: begin-concurrent-pnu)
13:49
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)
13:44
Merge enhancements from trunk, especially the enhanced sqlite3_normalized_sql() interface. (check-in: 47b73f6b user: drh tags: begin-concurrent)
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)
