| 13:17 | Fix a (almost always harmless) read past the end of a memory allocation that comes about because the Expr.pTab field is checked on an EXPR_REDUCEDSIZE Expr object before checking the Expr.op field to know that the Expr.pTab field is meaningless. check-in: e098de69 user: drh tags: trunk | |

2015-01-24

| 19:57 | Have fts5 store rowids in ascending order. Query speed is virtually the same regardless of rowid order, and ascending order makes some insert optimizations easier. check-in: 5206ca60 user: dan tags: fts5 | |
| 12:12 | In the command-line shell, make sure stderr is unbuffered so that it automatically flushes. This has always been the case already for unix and on Windows when the output is a console, but apparently was not the case on Windows when the output was a pipe. check-in: 2a9ea9b4 user: drh tags: trunk | |

| 19:48 | An alternative way of implementing the assert() that verifies the relative values of KeyInfo.nField+KeyInfo.nXField and the number of columns in a record. This version of the assert() only fires when the high-speed comparison routines are used - which is to say it only fires when the constraint actually matters. check-in: bf744b49 user: drh tags: tkt-f97c4637 | |
