Changes In Branch fkey-missing-indexes Excluding Merge-Ins
This is equivalent to a diff from 8d646905b8 to 1268dc7771
2016-12-16
| ||
18:43 | Add the ".lint fkey-indexes" command to the command-line shell. (check-in: 94689e3bda user: drh tags: trunk) | |
18:41 | Fix minor issues with the ".lint" command implemention in the shell and the shell help text related to ".lint". (Closed-Leaf check-in: 1268dc7771 user: drh tags: fkey-missing-indexes) | |
17:28 | Change ".fkey_missing_indexes" to ".lint fkey-indexes". (check-in: ee621ade38 user: dan tags: fkey-missing-indexes) | |
15:05 | Fix a problem causing the planner to generate sub-optimal plans for some queries that use recursive WITH sub-queries with LIMIT clauses. (check-in: 053a149cc8 user: dan tags: trunk) | |
01:09 | Merge enhancements from trunk, and especially the ability to use temp.sqlite_master as an alias for sqlite_temp_master. (check-in: 994a4401f5 user: drh tags: pragma-as-vtab) | |
01:00 | All temp.sqlite_master to be used as an alias for sqlite_temp_master. (check-in: 8d646905b8 user: drh tags: trunk) | |
2016-12-15
| ||
18:59 | Do exponential rather than linear expansion of the SrcList.a array when appending new elements, to reduce the number of malloc() calls. (check-in: 4e3749127e user: drh tags: trunk) | |
