5c327dbb46 http://www.sqlite.org/cvstrac/tktview?tn=2046 
The virtual table interface allows for a cursor to field multiple
xFilter() calls.  For instance, if a join is done with a virtual
table, there could be a call for each row which potentially matches.
Unfortunately, fulltextFilter() assumes that it has a fresh cursor,
and overwrites a prepared statement and a malloc'ed pointer, resulting
in unfinalized statements and a memory leak.

This change hacks the code to manually clean up offending items in
fulltextFilter(), emphasis on "hacks", since it's a fragile fix
insofar as future additions to fulltext_cursor could continue to have
the problem. (CVS 3521)

debbcdfead Require a minimum fanout for interior nodes. This prevents cases 
where excessively large terms keep the tree from finding a single
root.  A downside is that this could result in large interior nodes in
the presence of large terms, which may be prone to fragmentation,
though if the nodes were smaller that would translate into more levels
in the tree, which would also have that problem. (CVS 3510)

9d5586fc9f Make memset() uses less error-prone. 
http://www.sqlite.org/cvstrac/tktview?tn=2036,35 describes some cases
where we were passing memset() a length which was the sizeof a
pointer, rather than the structure pointed to.  Instead, wrap this
idiom up in CLEAR() and SCRAMBLE() macros. (CVS 3488)

87f1d16bdb Replace the DocList and DocListReader structures. The new structures 
distinguish reading from a static buffer from writing to a dynamic
buffer.  This allows n-way doclist merging, and in-place merging of
segment leaf nodes, which together cut segment merge times in half. (CVS 3486)

9289cba076 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. (CVS 3484)

b2f4d0173a Make fts1.c not rely on nul-terminated strings. Mostly a matter of 
making sure we always pass around ptr/len, but there were a few places
where we actually relied on nul-termination.

An earlier change had additionally changed appropriate
sqlite3_bind_text() calls to sqlite3_bind_blob().  I've found that
this changes what's actually stored in the database, so backed those
changes out.  Also (and this is weird), I found that I could no longer
do straight-forward = queries against %_term.term at a command-line. (CVS 3379)
