| 16:52 | Make SQLITE_MFS_NSHARD a compile time setting. (check-in: b9a7415190 user: dan tags: mutexfree-shmlock) | |
| 15:51 | Add extra tests to shmlock.test (direct testing of xShmLock methods). (check-in: d2c785f94c user: dan tags: mutexfree-shmlock) | |
| 15:24 | Rework the SQLITE_MUTEXFREE_SHMLOCK code to reduce contention. (check-in: d9157dd176 user: dan tags: mutexfree-shmlock) | |
| 09:45 | Avoid a mutex in-and-out in unixShmBarrier() on this branch. Use __sync_synchronize() instead. (check-in: a8c5fd86ce user: dan tags: mutexfree-shmlock) | |
|
2018-12-09
| ||
| 18:55 | New test case for ticket [1d958d90596593a77420e59]. (check-in: b7bf3c9832 user: drh tags: trunk) | |
|
2018-12-08
| ||
| 20:30 | Do not use a partial index as a table scan in an IN operator. Fix for ticket [1d958d90596593a77420e59]. (check-in: 15bc915dd7 user: drh tags: trunk) | |
|
2018-12-07
| ||
| 20:26 | Remove a line of code from VACUUM that is no longer needed, due to the change that allows ATTACH to run within a transaction. (check-in: a92c398fc5 user: drh tags: trunk) | |
| 16:32 | Fix the sqlite3_normalized_sql() interface so that it renders double-quoted string literals as "?". (check-in: 0d8e150434 user: drh tags: trunk) | |
| 03:01 | Fix dbfuzz2.c so that it works with -DSQLITE_OMIT_INIT (check-in: 9ad796a882 user: drh tags: trunk) | |
| 01:56 | Fix the sqlite3ExprDup() function so that it correctly duplicates the Window object list on a Select that contains window functions. Fix for ticket [f09fcd17810f65f717]. (check-in: db5ed2268e user: drh tags: trunk) | |
|

| 22:12 | Performance improvement: Avoid using sqlite3WalkerSelectExpr() and sqlite3WalkerSelectFrom() twice, so that the compiler will in-line their implementation. (Closed-Leaf check-in: 2b9258b8b0 user: drh tags: ticket-f09fcd17810f) | |
| 22:04 | Fix the sqlite3ExprDup() routine so that it makes complete duplications of subqueries containing window functions. (check-in: 940174543e user: drh tags: ticket-f09fcd17810f) | |
| 20:18 | Experimental changes to (optionally) allow double-quoted strings to be checked against known identifiers. (Leaf check-in: 73a6b8c1b9 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: a9a3b53264 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: f1b18d44ff 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: 8f4cb9dd33 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: 53d3b169d8 user: drh tags: trunk) | |
| 16:50 | When saving off the value of sqlite3.flags, take care to preserve all 64 bits. (check-in: 9c6dbcfab5 user: drh tags: trunk) | |
| 16:11 | Issue a warning whenever a double-quoted string literal is used. (check-in: ac9ad50430 user: drh tags: trunk) | |
| 03:59 | Invoking the sqlite3_trace() or sqlite3_trace_v2() interfaces cancels any sqlite3_profile() that is running. (check-in: ec63d3506b user: drh tags: trunk) | |
| 02:01 | Remove the unused pColHash field from the Table object. (check-in: 3a2c047989 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: ea50815bf8 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: 1a1a59c6c5 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: 272dc74fd0 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: e8540377ec user: drh tags: trunk) | |
| 23:25 | Bungled checkin. Ignore. (Closed-Leaf check-in: 9b6e9a6e45 user: drh tags: mistake) | |
| 21:55 | Fix an imbalanced lock problem in sqlite3Normalize() introduced by the simplification in [94ea6379178e3ff6a]. (check-in: f69624373e user: drh tags: trunk) | |
| 19:42 | Increase the version number to 3.27.0 for the next development cycle. (check-in: 8f8d682825 user: drh tags: trunk) | |
| 18:28 | Merge enhancements and the ALTER TABLE bug fix from trunk. (check-in: edfc2acfcd user: drh tags: apple-osx) | |
| 17:48 | Simplifications to the sqlite3_normalized_sql() implementation. (check-in: 94ea637917 user: drh tags: trunk) | |
| 13:49 | Ensure that ALTER TABLE modifies table and column names embedded in WITH clauses that are part of views and triggers. (check-in: f44bc7a8b3 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: 7da617e97e user: drh tags: trunk) | |

| 21:16 | When compiled with SQLITE_ENABLE_NORMALIZE, always have sqlite3_exec() enable the SQLITE_PREPARE_NORMALIZE flag. (Leaf check-in: 28643d837d user: mistachkin tags: execWithNormalize) | |
| 16:51 | Add the "index_usage" utility program. (check-in: df95455213 user: drh tags: trunk) | |
| 14:33 | Performance improvement in sqlite3_step() by creating a new mTrace flag for the legacy xProfile pointer that is set by sqlite3_profile(). (check-in: e28584e8bc user: drh tags: trunk) | |
| 13:51 | Small performance increase in sqlite3_step() for the common case where it returns SQLITE_ROW. (check-in: 8934482652 user: drh tags: trunk) | |
|
2018-12-03
| ||
| 23:57 | Reduce the size of the parser tables generated by Lemon by splitting the yyRuleInfo structure into separate yyRuleInfoLhs and yyRuleInfoNRhs arrays. (check-in: 70fe8ec2ae user: drh tags: trunk) | |
| 17:40 | Remove the unused sqlite3Fts5UnicodeNCat() function. (check-in: 7149dacf1d user: drh tags: trunk) | |
| 16:14 | Add the "remove_diacritics=2" option to the unicode61 tokenizer in both FTS5 and FTS3/4. (check-in: 06177f3f11 user: dan tags: trunk) | |
| 14:58 | Update the autoconf makefile for MSVC. (check-in: 675aba1f8b user: mistachkin tags: trunk) | |
| 01:58 | Remove two lines of unnecessary code, for a very small performance increase and size decrease. (check-in: 15824ccda0 user: drh tags: trunk) | |
| 01:47 | Fix a parser bug in the use of parentheses around table-valued functions. (check-in: 58a51123d1 user: drh tags: trunk) | |
