| 19:29 | Work toward improving analysis and code generation for DISTINCT and aggregate queries. (Leaf check-in: 129083bd5e user: drh tags: better-distinct-agg) | |
| 17:29 | In the ICU extension toupper() and tolower() SQL functions, avoid calling u_strToUpper() or u_strToLower() a second time if the buffer passed to the first invocation turns out to be large enough. (check-in: d23e581351 user: dan tags: trunk) | |
| 16:40 | Add the SF_HasAgg constant (currently unused). Also enhance the comments on many other constant definitions to detail constraints on their values. (check-in: 7b7a69d098 user: drh tags: trunk) | |
| 15:44 | Correctly interpret negative "PRAGMA cache_size" values when determining the cache-size used for sorting large amounts of data (i.e. the functionality in vdbesort.c). (check-in: 79147dca87 user: dan tags: trunk) | |
| 15:38 | Add some missing testcase() macros to the pushDownWhereTerms() routine. (check-in: 67d7f79c5e user: drh tags: trunk) | |
| 13:35 | Rename WhereInfo.pResultSet to pDistinctSet to more accurately reflect what it represents. (check-in: 5317961411 user: drh tags: trunk) | |
| 13:16 | Since the return value of sqlite3OsClose() is always ignored, we might as well make it "void" instead of "int", and thereby save 50 bytes in the compiled binary. (check-in: 7ee570e7a9 user: drh tags: trunk) | |
