| 18:38 | Propagate the -ldl and -lpthread flags, if needed, into sqlite3.pc, per request in [forum:44a58c807353162f | forum post 44a58c807353162f]. This resolves usage of that pkgconf file on some OSes. (Leaf check-in: b4db6ddeed user: stephan tags: branch-3.50) | |
| 18:32 | Add 'reconfigure' target to Makefile.in to re-run the configure script with the same flags it was generated with. (Leaf check-in: c60907e77b user: stephan tags: trunk) | |
| 17:20 | Propagate the -ldl and -lpthread flags, if needed, into sqlite3.pc, per request in [forum:44a58c807353162f | forum post 44a58c807353162f]. (check-in: 64f5f14322 user: stephan tags: trunk) | |
| 14:24 | Merge fixes from trunk into the empty-table-optimizations branch (Leaf check-in: 6f98b16d21 user: drh tags: empty-table-optimizations) | |
| 12:25 | Fix harmless compiler warnings. (check-in: 13af4acebe user: drh tags: trunk) | |
| 11:48 | Remove an ALWAYS() added by [960a8e6fc91f4] that turns out to be false in some cases of malformed SQL. (check-in: cc8171461b user: drh tags: trunk) | |
| 11:06 | Do not allow the EXISTS-to-JOIN optimization if the EXISTS clause is based on a view, since that view might expand into a join. (check-in: 872c41fedd user: drh tags: empty-table-optimizations) | |
| 10:26 | Improve the early-termination optimization so that it works in queries which use the LIKE optimization in the outer loop. (check-in: b4e4d14824 user: drh tags: empty-table-optimizations) | |
| 10:17 | Merge trunk into column-text-blob-v2 branch. (Leaf check-in: f73460d4f0 user: stephan tags: column-text-blob-v2) | |
| 10:10 | Tweak for coverage testing of valueToTextV2(). This changes passes through coverage testing but doesn't look quite right to me, in that this part now differs from its counterpart in valueToText() (which doesn't need this to get coverage for what amounts to the same path). (check-in: dae572912f user: stephan tags: column-text-blob-v2) | |

| 16:05 | Fix a few cases where LIMIT clauses that were part of scalar sub-queries on virtual tables were not being passed to xBestIndex methods correctly. (check-in: 960a8e6fc9 user: dan tags: trunk) | |
| 15:50 | Improvements to sqlite3_vtab_rhs_value() logging in the ext/misc/vtablog.c extension. (Closed-Leaf check-in: 25131ee84f user: drh tags: vtab-limit-fixes) | |
| 15:32 | Make the value of an explicit LIMIT clause on a scalar sub-query available to xBestIndex for simple "LIMIT 0" and "LIMIT 1" queries. (check-in: 33b6a63caa user: dan tags: vtab-limit-fixes) | |
| 14:28 | Make handling of LIMIT clauses in correlated sub-queries on virtual tables more efficient. (check-in: 7214cb2a5b user: dan tags: vtab-limit-fixes) | |

| 20:46 | Merge in the exists-to-join optimization that has been modified to relax the requirement of having an indexed join constraint. (check-in: 1c1aef2b7f user: drh tags: empty-table-optimizations) | |
| 17:43 | Fix VDBE coverage (check-in: ff593a16d6 user: drh tags: empty-table-optimizations) | |
| 15:29 | Correct mis-placed OOM checks in valueToTextV2(). (check-in: 9226a2a3c6 user: stephan tags: column-text-blob-v2) | |
| 14:53 | Early exit if one of the inner loops of a 3-way or larger join is an empty table. (check-in: eaad6ac707 user: drh tags: empty-table-optimizations) | |
| 13:24 | Per /chat and forum discussions: (A) Remove the value type output pointer from text/blob_v2(). (B) Teach blob_v2() to return an opaque non-NULL pointer for length-0 blobs. (check-in: c96539beb5 user: stephan tags: column-text-blob-v2) | |
| 13:19 | If the LHS for an EXCEPT or INTERSECT operator is empty, skip over the computation of the RHS. (check-in: 13f096ae8a user: drh tags: empty-table-optimizations) | |
| 11:47 | Improve the bytecode for joins such that it exits earlier if it determines that no output is possible. (check-in: 2d2b61cba4 user: drh tags: trunk) | |
| 07:52 | Add test1.c tcl bindings for sqlite3_column_text/blob_v2(). Replace, essentially randomly, some of the v1 API calls in capi2.test and capi2.test with the v2 calls to ensure identical results. Add a couple new tests comparing results between v1 and v2. (check-in: a3ca0adbaf user: stephan tags: column-text-blob-v2) | |

| 21:33 | Remove an #if 0 block. (check-in: 0363c430b5 user: stephan tags: column-text-blob-v2) | |
| 21:06 | Have sqlite3_value/column_text/blob_v2() return MISUSE for a NULL input object or output target only if SQLITE_ENABLE_API_ARMOR is in effect, for consistency with their sibling APIs. (check-in: 6290a8eadd user: stephan tags: column-text-blob-v2) | |
| 20:56 | Have sqlite3_value/column_text/blob_v2() unconditionally return MISUSE for a NULL input object or output target, rather than only when API_ARMOR is in effect. This is debatable. (check-in: c8edbfc7e8 user: stephan tags: column-text-blob-v2) | |
| 20:32 | Improved byte-code comments for the short-circuit optimization of [0083d5169a46104a], to aid in debugging. (check-in: 113f9d10e3 user: drh tags: trunk) | |

| 17:36 | Cache and reuse virtual table cursors in the bytecode engine. (check-in: 2d187d4232 user: drh tags: trunk) | |
| 16:38 | Experimentally add another output pointer to the text/blob_v2() family which gets the sqlite3_value_type() assigned to it if it's not NULL, based on feedback in the forum. (check-in: 4aab781d2a user: stephan tags: column-text-blob-v2) | |
| 16:21 | Avoid an assert() failure in fts5 that may occur when processing corrupt records. (check-in: 8afd6ca857 user: dan tags: trunk) | |
| 15:13 | Merge trunk fixes into the empty-table-optimizations branch. (Closed-Leaf check-in: 63306e447e user: drh tags: empty-table-optimizations) | |
| 14:44 | Simplify the column_text/blob_v2() JS tests a bit and correct the text_v2() tests to call into both the column and value variants. (check-in: d5cb808043 user: stephan tags: column-text-blob-v2) | |
| 13:01 | Initial implementations of sqlite3_column_text_v2(), sqlite3_column_blob_v2(), and their JS/WASM bindings/tests. (check-in: 1d065231ab user: stephan tags: column-text-blob-v2) | |

| 12:49 | When attempting to optimize "expr AND false" to "false" and "expr IN ()" to "false", take care not to delete aggregate functions in the "expr" as doing so can change the meaning of the query. (check-in: 355c7902de user: drh tags: branch-3.50) | |
| 12:43 | When attempting to optimize "expr AND false" to "false" and "expr IN ()" to "false", take care not to delete aggregate functions in the "expr" as doing so can change the meaning of the query. See [forum:/forumpost/f4878de3e7dd4764|forum thread f4878de3e7]. (check-in: 77397bd67d user: drh tags: trunk) | |
| 09:02 | Add tests which demonstrate the difference in behavior for zero-length results in sqlite3_value_text_v2() (empty string) vs sqlite3_value_blob_v2() (NULL). (check-in: 2e7cf00d16 user: stephan tags: column-text-blob-v2) | |
| 00:34 | Add JS tests for SQLITE_ENABLE_API_ARMOR-shielded sqlite3_value_blob/text_v2() misuse. (check-in: 3c0de5b33c user: stephan tags: column-text-blob-v2) | |

| 23:49 | Add JS bindings for sqlite3_value_text/blob_v2() and add basic JS tests for text_v2(). (check-in: 096c745f38 user: stephan tags: column-text-blob-v2) | |
| 23:17 | Restart this branch using a different take: add new "v2" routines instead of refactoring the old ones, which eliminates any performance impact or risk of behavior change for existing APIs. None of this code is actually called from anywhere yet. (check-in: b0b1b4ccb9 user: stephan tags: column-text-blob-v2) | |
| 22:15 | Initial experimental internal changes needed to support a hypothetical sqlite3_column_text/blob_v2(), as discussed in [forum:402a837960d9de45 | forum post 402a837960d9de45]. This is just the first step: this change needs to cascade upwards a couple of levels, remove one level of porting-crutch API, and go through performance comparisons before we'll know whether it's really feasible. make devtest passes but there are corner error cases which require more precise testing to ensure that there are no visible changes in behavior.
