20:47 | Import the automatic comment generating changes from trunk. (check-in: 8bb51da130 user: drh tags: omit-rowid) | |
20:40 | Automatically generated comments on many VDBE opcodes when in SQLITE_DEBUG mode. Comments derive from the "Synopsis:" field added to each opcode definition in vdbe.c. (check-in: 5f310c6a22 user: drh tags: trunk) | |
16:14 | Improved comments on the constraint checking logic. (check-in: 141a38a7a6 user: drh tags: omit-rowid) | |
