Don't store empty segments. When inserting empty strings, the code
was writing out a segment made up of a single leaf node containing the
\0 header. LeafReader assumed that leaf nodes always contained at
least one term, so assertions would fail.
While it would be possible to support reading and merging empty segments, there's no reason to do so. While this change could have been done in writeZeroSegment(), I put it in leafWriterFlush() so that it would work right if segmentMerge() created an empty segment, which could happen with future changes to how deleted documents are handled.

| 23:36 | dup fts1 tests and edit for fts2. fts1porter.test omitted because it depends on being able to poke through to %_term table. (CVS 3482) (check-in: 2806c34158 user: shess tags: trunk) | |

| 23:15 | Convert fts2 to store data in a way which allows for much faster updates. Groups of documents form segments which are encoded in a btree layered over a table of blocks, with various tricks to make merges fast. This performs 20x-25x faster than fts1 when loading the Enron corpus, and is only slightly slower for queries. (CVS 3474) (check-in: 85272b2f53 user: shess tags: trunk) | |

| 21:48 | Fix incorrect doclist initialization in term_select_all(). docListRestrictColumn() generates a DL_POSITIONS doclist, which means that after the first doclist is processed, the second doclist is initialized as DL_POSITIONS, but with DL_POSITIONS_OFFSETS data. (Note that DL_DEFAULT is now DL_POSITIONS, which masks this bug.) (CVS 3467) (check-in: 144e3f11e2 user: shess tags: trunk) | |

Implemented UPDATE for full-text tables.
We handle an UPDATE to a row by performing an UPDATE on the content table and by building new position lists for each term which appears in either the old or new versions of the row. We write these position lists all at once; this is presumably more efficient than a delete followed by an insert (which would first write empty position lists, then new position lists).

| 20:56 | When gathering a doclist for querying, don't discard empty position lists until the end; this allows empty position lists to override non-empty lists encountered later in the gathering process. This fixes #1982, which was caused by the fact that for all-column queries we weren't discarding empty position lists at all. (CVS 3433) (check-in: 111ca61671 user: adamd tags: trunk) | |
