| 16:16 | Add implementation of last_value() window function. check-in: 2493ce1a40 user: dan tags: exp-window-functions | |
| 15:16 | Use an OP_NotFound opcode to cancel futile IN operators early. The current implementation is suboptimal because it always runs teh OP_NotFound. This still needs to be enhanced to only do the OP_NotFound if no results have been seen on the current loop. check-in: 87a9fc504f user: drh tags: multikey-opt-idea | |
| 13:54 | Merge trunk changes. check-in: 047295c588 user: drh tags: multikey-opt-idea | |
| 13:43 | Update and correct the documentation on the OP_OpenRead, OP_OpenWrite, and OP_ReopenIdx opcodes. No code changes other than the addition of an assert(). check-in: 8a0b730d0e user: drh tags: trunk | |

|
2018-06-02
| ||
| 21:04 | Add support for window functions row_number(), rank(), dense_rank() and percent_rank(). check-in: 91c1cb7a21 user: dan tags: exp-window-functions | |
| 19:14 | Avoid using a misaligned pointer. check-in: 1ecb3aa13d user: drh tags: trunk | |
| 19:01 | Fix the usage of posix_fallocate() so that it correctly responds to EINVAL returns. check-in: ce2c3e7a87 user: drh tags: trunk | |
| 17:00 | Update a test case in malloc5.test to take into account that malloc() sometimes returns slightly more space than requested. check-in: 3d5eae1c26 user: dan tags: trunk | |
| 16:32 | Work around a sanitizer warning about a pointer being only 4-byte aligned instead of 8-byte aligned. Closed-Leaf check-in: 1b807b51cd user: drh tags: align8-fix | |
| 14:37 | Proposed fix for the use of posix_fallocate() so that it handles EINVAL returns correctly. Closed-Leaf check-in: ab3a5539db user: drh tags: einval-from-fallocate | |

| 11:31 | Ensure that sqlite3AuthRead() is only call for TK_COLUMN and TK_TRIGGER expression nodes. This fixes a harmless assert() identified by OSSFuzz. Move the assert() into a position where it is tested even if the authorizer is disabled. check-in: d0c3beef7c user: drh tags: trunk | |
|

| ||
| 21:00 | Allow an entire partition to be cached in a temp table for all types of window frames. This is required by nth_value() and others. check-in: b5b18f6613 user: dan tags: exp-window-functions | |
| 13:30 | Fix a bug in the SQLITE_ENABLE_SORTER_REFERENCES code causing an out-of-bounds array reference. check-in: 8cadaf587d user: dan tags: trunk | |

| 01:14 | Fix the parser so that it builds with -DSQLITE_OMIT_CTE. check-in: 86ee267ee8 user: drh tags: trunk | |
| 00:59 | Fix a harmless compiler warning. check-in: 8d02c7a6a0 user: drh tags: trunk | |
| 00:54 | Demonstration code on a possible technique for optimizing the use of IN operator on columns to the right of multicolumn indexes. If the OP_Noop generated where were really a new opcode that checked to see if there existed any entries in the index with a matching prefix, it might prevent unnecessary iterations of the IN operator. check-in: 92f0fe155d user: drh tags: multikey-opt-idea | |

| 19:12 | Increase the number of database handles opened by test script oserror.test to provoke an "out of file-descriptors" error to 20000 (from 2000). check-in: 3b00f73456 user: dan tags: trunk | |

| 14:06 | Fix some test script issues caused by recent EXPLAIN QUERY PLAN enhancements. check-in: f808e22831 user: dan tags: trunk | |
| 13:25 | Do not run test file "resetdb.test" as part of permutation "inmemory_journal". check-in: 4921e5bae4 user: dan tags: trunk | |

| 23:59 | The geopoly virtual table seems to be working. But only thinly tested so far. check-in: 4288f1ad59 user: drh tags: rtree-geopoly | |
| 18:30 | Further window frame tests and fixes. check-in: e74c6e9185 user: dan tags: exp-window-functions | |
| 18:29 | Do not require a statement journal in cases where REPLACE conflict handling is used to insert a single row, so long as the REPLACE operation cannot fire any triggers or foreign key actions. check-in: 469a62ca33 user: dan tags: trunk | |
| 18:25 | When compiling with SQLITE_DEBUG, add run-time checks to ensure that no statement aborts unless either there have been no writes or else there is a statement journal. check-in: ce99c77244 user: drh tags: trunk | |
| 17:43 | Fix the build so that it works with -DSQLITE_TEST_REALLOC_STRESS Closed-Leaf check-in: 90ba2b2e5c user: drh tags: stmt-journal-testing | |
| 17:31 | When compiling with SQLITE_DEBUG, add run-time checks to ensure that no statement aborts unless either there have been no writes or else there is a statement journal. check-in: 5a4542dbcf user: drh tags: stmt-journal-testing | |
| 13:23 | Untested incremental check-in. Add the geopoly_xform() function. Complete basic logic for the geopoly virtual table. check-in: ed06cc3256 user: drh tags: rtree-geopoly | |

| 21:17 | More fixes for different window frame types. check-in: 2c85668a0f user: dan tags: exp-window-functions | |
| 20:04 | Merge the ability to plan virtual table queries using overloaded functions. check-in: 2c2a202c14 user: drh tags: rtree-geopoly | |
| 18:03 | Experimental change that allows overloaded functions to be analyzed by the xBestIndex method and used by the xFilter method of a virtual table. Leaf check-in: a353b1d7ee user: drh tags: vtab-func-constraint | |
| 16:00 | Store application-defined function names as lower-case to avoid the need for case conversions before calling xFindFunction on virtual tables. Avoid using lookaside to store the destructors for application defined functions, as lookaside should be reserved for transient allocations. check-in: 777189ce88 user: drh tags: trunk | |
| 13:55 | Add a single sentence of documentation about the virtual table scan flags. No changes to code. check-in: 27b4fa5dd0 user: drh tags: trunk | |
