| 22:09 | Propagate prefix flag through implementation of doclist query code. Also implement correct prefix-handling for traversal of interior nodes of segment tree. A given prefix can span multiple children of an interior node, and from there the branches need to be followed in parallel. (CVS 3889) (check-in: cae844a0 user: shess tags: trunk) | |
| 17:52 | Lift docListMerge() call out of loadSegmentLeavesInt() for prefix search. Doclists from multiple prefix matches will need a union merge function, which will have to logically happen across a segment before doclists are merged between segments. (CVS 3887) (check-in: 7ddb8266 user: shess tags: trunk) | |

| 22:02 | Break interior-node and leaf-node readers apart in loadSegment(). Previously, the code looped until the block was a leaf node as indicated by a leading NUL. Now the code loops until it finds a block in the range of leaf nodes for this segment, then reads it using LeavesReader. This will make it easier to traverse a range of leaves when doing a prefix search. (CVS 3884) (check-in: 9466367d user: shess tags: trunk) | |
| 21:24 | Lift code to traverse interior nodes out of loadSegment(). Refactoring towards prefix searching. (CVS 3882) (check-in: 25935db7 user: shess tags: trunk) | |
| 21:02 | Refactor fts2 loadSegmentLeaf() in preparation for prefix-searching. Prefix-searching will want to accumulate data across multiple leaves in the segment, using LeavesReader instead of LeafReader is the first step in that direction. (CVS 3881) (check-in: 22ffdae4 user: shess tags: trunk) | |

| 18:36 | Fix bug in fts2 handling of OR queries. When one doclist ends before the other, the code potentially tries to read past the end of the doclist. http://www.sqlite.org/cvstrac/tktview?tn=2309 (CVS 3862) (check-in: dfac6082 user: shess tags: trunk) | |

| 20:45 | Fix crash in delete when existing row has null fields. Previous code assumed that the row had values in all columns, sigh. Fixes bug http://www.sqlite.org/cvstrac/tktview?tn=2289 . (CVS 3833) (check-in: 81be7290 user: shess tags: trunk) | |
