| ||
| 14:01 | If an SQLITE_IOERR error is encountered as part of an atomic commit on an F2FS file-system, retry the commit in legacy journal mode. (check-in: 2e0357c2 user: dan tags: trunk) | |
| 13:55 | Fix for builds without SQLITE_ENABLE_BATCH_ATOMIC_WRITE. (Closed-Leaf check-in: b10ec14e user: dan tags: exp-retry-atomic-commit) | |
|
2018-07-16
| ||
| 20:44 | Add new file doc/F2FS.txt, containing notes on the way SQLite uses the F2FS atomic commit feature. (check-in: 59efb1bf user: dan tags: exp-retry-atomic-commit) | |
| 11:32 | Minor simplification to sqlite3RollbackAll(). (check-in: 432fdc22 user: drh tags: trunk) | |

| 20:25 | If an SQLITE_IOERR error is encountered as part of an atomic commit on an F2FS file-system, retry the commit in legacy journal mode. (check-in: 1c41250f user: dan tags: exp-retry-atomic-commit) | |
|
2018-07-13
| ||
| 20:28 | Remove an unused function declaration from fts5. (check-in: 148d9b61 user: dan tags: trunk) | |
| 19:52 | Add the "categories" option to the unicode61 tokenizer in fts5. (check-in: 80d2b9e6 user: dan tags: trunk) | |
|
2018-07-12
| ||
| 19:14 | Add a test-control to disable the skip-scan optimization. (check-in: 650a3fe0 user: dan tags: trunk) | |
| 11:28 | Add a test case to check that SQLITE_DBCONFIG_RESET_DATABASE can be used with wal mode databases even if there are active readers. (check-in: 6145f5b3 user: dan tags: trunk) | |
|
2018-07-11
| ||
| 13:34 | On an UPSERT when the order of constraint checks is rearranged, make sure that the affinity transformations on the inserted content occur before any of the constraint checks. Fix for ticket [79cad5e4b2e219dd197242e9e5f4e]. (check-in: d120c45f user: drh tags: trunk) | |
| 03:27 | Adjustments to VdbeCoverage macros to deal with byte-code branches that can never be taken in some directions. (check-in: b170c009 user: drh tags: trunk) | |
|
2018-07-10
| ||
| 23:31 | Remove incorrect ALWAYS() macros from the window function logic. (check-in: 94ac51cc user: drh tags: trunk) | |
| 22:24 | Add VdbeModuleComment()s on the three main code generators for window functions. (check-in: f7c239e9 user: drh tags: trunk) | |
| 20:50 | Minor comment changes. Add ALWAYS() macros on some unreachable branches in the xStep() methods of built-in window functions. (check-in: f2057542 user: drh tags: trunk) | |
| 19:48 | Identify Select objects within a single statement using small sequential integers rather than "0x%p". This is more readable and yields the same result on successive runs. (check-in: a7cdc5bc user: drh tags: trunk) | |
| 18:50 | Modify tests in window3.test to be tolerant of rounding errors when comparing floating point values. (check-in: 7c26c443 user: dan tags: trunk) | |
| 17:26 | Fix a problem with using scalar sub-selects in window function queries. (check-in: 687fe532 user: dan tags: trunk) | |
| 17:10 | Further improvements to bytecode branch testing. Fix cases where the macros said a branch could not be taken when in fact it could be. Alter some window function branch coverage macros to indicate that comparison operands cannot be NULL. (check-in: 76e42b70 user: drh tags: trunk) | |
| 16:04 | Enhancements and improved documentation to the byte-code branch coverage testing logic. Provide new macros that allow the code to specify that some branch instructions can never take the NULL path and that the OP_Jump opcode is only interested in equal/not-equal. The SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly differently (it provides the callback with a bitmask of the branch action, rather than an integer). (check-in: cd2da7e1 user: drh tags: trunk) | |
| 07:39 | Fix a harmless warning about comment formatting in the previous check-in. Simplify the ORDER BY dereferencing logic so that it avoids unreachable branches. (check-in: 0f6ec605 user: drh tags: trunk) | |
| 07:25 | Assert that if two functions compare equal in every other way, then they must both have OVER clauses, or neither has an OVER clause. Use this fact to simplify expression comparison. (check-in: 52559ad5 user: drh tags: trunk) | |
| 06:47 | Enhance the sqlite3ExprCompare() routine so that it knows to compare the OVER clause of window functions. (check-in: 0a7649af user: drh tags: trunk) | |
| 06:32 | Enhance the TreeView mechanism so that it shows the window function data structures as part of the abstract syntax tree. (check-in: a2c0e1be user: drh tags: trunk) | |
| 05:11 | New VDBE comments and coverage macros. (check-in: a9a30726 user: drh tags: trunk) | |
|

| ||
| 22:49 | Fixes for various harmless compiler warnings. (check-in: 5023b1b8 user: drh tags: trunk) | |
| 20:58 | Add a comment to restriction (6) of the push-down optimization. No changes to code. (check-in: 0c8a2f25 user: drh tags: trunk) | |
| 20:41 | Add an ALWAYS() around a branch in sqlite3BtreeSkipNext() that we believe must always be true. (check-in: 12be361a user: drh tags: trunk) | |
| 18:55 | Avoid leaving view-definitions with an incomplete set of column names/types in the in-memory schema if an OOM strikes while allocating the same. (check-in: 1ddbb537 user: dan tags: trunk) | |
| 18:11 | Add a couple of OOM tests. (check-in: 50de2a0d user: dan tags: trunk) | |
| 17:33 | Remove redundant branches in window function processing. (check-in: 8fdaf3f3 user: drh tags: trunk) | |
| 16:24 | Simplification to the grammar rules for window functions. Fix a memory leak that can follow an OOM while parsing a comma-separated list of window definitions. (check-in: a568f9c9 user: drh tags: trunk) | |
| 13:31 | Throw an error if the second argument passed to nth_value() is not a positive integer. (check-in: 1a06e57a user: dan tags: trunk) | |
| 06:51 | Fix a bad assert() in window.c. (check-in: fe8aaf0c user: dan tags: trunk) | |
| 02:37 | Simplification to the logic that detects misuse of the application-defined function creation interfaces. (check-in: 8f21d778 user: drh tags: trunk) | |
| 02:02 | During WITHOUT ROWID table creation, if the sqlite3CreateTable() call fails due to an authorizer denying the INSERT into the sqlite_master table, then detect this fact and abort the CREATE TABLE early, to avoid an assertion fault. (check-in: 164b1641 user: drh tags: trunk) | |
|
2018-07-08
| ||
| 01:02 | Identify specific FuncDef objects for window functions using the pointer to the function name (FuncDef.zName) rather than the pointer to the xStep method. This allows xStep method pointer to be replaced with a single noopStepFunc() procedure, and thus save having lots of different no-op step functions. (check-in: 410e13b0 user: drh tags: trunk) | |
|
2018-07-07
| ||
| 20:55 | Simplifications to the implementation of the sum() SQL function. (check-in: a8b13002 user: drh tags: trunk) | |
| 20:26 | Fix another problem with reusing LSM cursors for range scans. (check-in: ae3fc765 user: dan tags: trunk) | |
| 20:23 | Fix the JSON extension so that it can be compiled separately from the amalgamation. (check-in: 4b8cfe7b user: drh tags: trunk) | |
| 20:13 | Fix an LSM problem caused by using the same cursor for equality and range scans. (check-in: f05bead3 user: dan tags: trunk) | |
| 19:47 | Add ALWAYS() macros on results of sqlite3_aggregate_context() calls in xInverse() implements, since they can never fail. (check-in: fdef2a92 user: drh tags: trunk) | |
| 19:36 | Add an assert() to help verify that OP_AggInverse is never called on an accumulator that has not previously been processed by OP_AggStep. (check-in: 42138891 user: drh tags: trunk) | |
| 17:38 | Add missing VdbeCoverage() macro to window.c. (check-in: 63f4d306 user: dan tags: trunk) | |
| 17:30 | Fix a problem with the handling of NULL values in the min() window function. (check-in: b76f35b0 user: dan tags: trunk) | |
|
2018-07-06
| ||
| 17:19 | Try to improve the error messages for misformed frame specifications in window definitions. (check-in: 927b95a0 user: drh tags: trunk) | |
| 14:31 | Also disallow non-constant expressions in "<expr> PRECEDING" or "<expr> FOLLOWING" clauses. (check-in: a6dffecc user: dan tags: trunk) | |
| 14:15 | Ensure an error is returned if the user specifies an unsupported frame type. (check-in: 0f3f8fcd user: dan tags: trunk) | |
| 13:48 | Prevent "UNBOUNDED FOLLOWING" from being used as the starting boundary of a window-frame. And "UNBOUNDED PRECEDING" from being used as the ending boundary. (check-in: e51fdf66 user: dan tags: trunk) | |
| 13:25 | Remove some bad assert() statements from the implementations of window functions percent_rank() and cume_dist(). (check-in: 443f0c28 user: dan tags: trunk) | |
| 07:42 | Return an error if DISTINCT is used with a window-function (e.g. "count(DISTINCT <expr>) OVER (...)"). (check-in: d59bcc8e user: dan tags: trunk) | |
|
2018-07-05
| ||
| 21:22 | Use separate opcodes, OP_AggValue and OP_AggInverse, for the new callbacks associated with Window Functions, for improved readability of EXPLAIN output. (check-in: fa653805 user: drh tags: trunk) | |
| 20:33 | Update the recipe for resetting a database using SQLITE_DBCONFIG_RESET_DATABASE. (check-in: c43dd23f user: dan tags: trunk) | |
