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.

This directory contains source code to
SQLite: An Embeddable SQL Database Engine
To compile the project, first create a directory in which to place
the build products. It is recommended, but not required, that the
build directory be separate from the source directory. Cd into the
build directory and then from the build directory run the configure
script found at the root of the source tree. Then run "make".
For example:
tar xzf sqlite.tar.gz ;# Unpack the source tree into "sqlite"
mkdir bld ;# Build will occur in a sibling directory
cd bld ;# Change to the build directory
../sqlite/configure ;# Run the configure script
make ;# Run the makefile.
make install ;# (Optional) Install the build products
The configure script uses autoconf 2.50 and libtool. If the configure
script does not work out for you, there is a generic makefile named
"Makefile.linux-gcc" in the top directory of the source tree that you
can copy and edit to suite your needs. Comments on the generic makefile
show what changes are needed.
The linux binaries on the website are created using the generic makefile,
not the configure script. The configure script is unmaintained. (You
can volunteer to take over maintenance of the configure script, if you want!)
The windows binaries on the website are created using MinGW32 configured
as a cross-compiler running under Linux. For details, see the ./publish.sh
script at the top-level of the source tree.
