     the [sqlite3_db_config]([SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER])
     setting, or unless the first argument to fts3_tokenizer() is a [bound parameter].
<li> The two-argument version of [fts3_tokenizer()] accepts a pointer to the
     tokenizer method object even without
     the [sqlite3_db_config]([SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER]) setting
     if the second argument is a [bound parameter]
</ol>     
<li> Improved robustnessness against corrupt database files.
<li> Miscellaneous performance enhancements
<li> Established a Git mirror of the offical SQLite source tree. 
     The canonical sources for SQLite are maintained using the
     [https://fossil-scm.org/|Fossil DVCS] at [https://sqlite.org/src].
     The Git mirror can be seen at [https://github.com/sqlite/sqlite].

CREATE TEMP TABLE sqlite_parameters(
  key TEXT PRIMARY KEY,
  value ANY
) WITHOUT ROWID;
</codeblock>

<p>And if there is a entry in that table where the key column exactly matches
the name of parameter (including the initial "?", "$", ":", or "@" character)
then the parameter is assigned the value of the value column.  If no entry exists,
the parameter defaults to NULL.

<p>The ".parameter" command exists to simplify managing this table.  The
".parameter init" command (often abbreviated as just ".param init") creates
the temp.sqlite_parameters table if it does not already exist.  The ".param list"

<p><b>Using the ".breakpoint" shell command</b>

<p>The ".breakpoint" command in the CLI does nothing but invoke the
procedure named "test_breakpoint()", which is a no-op.

<p>If you have a script and you want to start debugging at some point
half-way through that script, simply set a breakpoing in gdb (or whatever
debugger you are using) on the test_breakpoint() function, and add a
".breakpoint" command where you want to stop.  When you reach that first
breakpoint, set whatever additional breakpoints are variable traces you
need.

<li>
<p><b>Disable the [lookaside memory allocator]</b>

Enable the [PRAGMA cell_size_check=ON] setting.

<li><p>
Do not enable memory-mapped I/O.
In other words, make sure that [PRAGMA mmap_size=0].

<li><p>
A malicously crafted database might be able to inject SQL by defining new
[CREATE TRIGGER|triggers] or [CREATE VIEW|views] in the schema that the
application does not anticipate.
Therefore, applications that read untrusted databases might want to 
scan the [sqlite_master] table to look for unexpected triggers and/or views
and might also want to deploy the SQL defense techniques described in
the previous section.
