|
2015-08-26
| ||
| 18:54 | Fix an assert() in pager.c that could fail in a concurrent transaction. (check-in: 69394ddaa2 user: dan tags: begin-concurrent) | |

| ||
| 19:10 | Add miscellaneous test cases for concurrent transactions. (check-in: 779b1d0e17 user: dan tags: begin-concurrent) | |
| 17:16 | If "PRAGMA integrity_check" is run while the database is being written by a CONCURRENT transaction, do not consider unreferenced pages to be an error. They may be part of the free-page list, which is not visible at the b-tree layer when running a CONCURRENT transaction. (check-in: f32b57b493 user: dan tags: begin-concurrent) | |
| 16:01 | Test that if a corrupt wal-index header is encountered when attempting to commit a concurrent transaction, SQLITE_BUSY_SNAPSHOT is returned to the caller. (check-in: c746e0bd20 user: dan tags: begin-concurrent) | |

| ||
| 22:06 | Remove duplicated line of code. (check-in: 47280f2a2b user: mistachkin tags: begin-concurrent) | |
| 20:54 | Remove some redundant code: Call sqlite3ResolveExprListNames() rather than calling sqlite3ResolveExprNames() in a loop - in two places. (check-in: bdaf66465b user: drh tags: trunk) | |
| 20:21 | Enhances the parser so that it accepts arbitrary expressions for the arguments of an index, though the code generator still rejects everything other than simple column names.

| 20:12 | Split out the bulk of the actual VDBE code generation logic from where.c into a new file, leaving behind the analysis logic. This makes the original where.c smaller and hopefully easier to edit. (check-in: faa0e420e9 user: drh tags: view-optimization) | |

| 22:33 | Split FROM-clause subquery flattening and code generation into separate loops. (check-in: be8e3fc70e user: drh tags: view-optimization) | |
| 20:27 | Provide one final Select tree dump prior to WHERE clause analysis when ".selecttrace 0x400" tracing bit is set with SELECTTRACE_ENABLED. Analysis and debug changes only - normal builds are unaffected. (check-in: 283bf0b64d user: drh tags: trunk) | |

| 18:09 | For FROM-clause subqueries that cannot be flattened, try to push relevant WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. Call this the "WHERE-clause push-down optimization". Do not confuse this with the completely different MySQL push-down optimization. (check-in: 6df18e949d user: drh tags: trunk) | |

| 01:35 | Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine. This is a stop-gap means of controlling the decision to manifest while we try to work out a better to make that decision automatically. (check-in: a29e117d7e user: drh tags: trunk) | |

| 15:10 | Disallow the use of "rowid" in CTEs - it has never worked correctly and it makes no sense, so we might as well make it an explicit error. Also: add the PRAGMA cell_size_check=ON command. (check-in: 19e2cebc12 user: drh tags: trunk) | |
