** mutex and returns a pointer to it.  If it returns NULL
** that means that a mutex could not be allocated. 
** SQLite will unwind its stack and return an error.  The argument
** to sqlite3_mutex_alloc() is one of these integer constants:
**
** <ul>
** <li>  SQLITE_MUTEX_FAST
** <li>  SQLITE_MUTEX_RECURSIVE
** <li>  SQLITE_MUTEX_STATIC_MASTER
** <li>  SQLITE_MUTEX_STATIC_MEM
** <li>  SQLITE_MUTEX_STATIC_MEM2
** <li>  SQLITE_MUTEX_STATIC_PRNG
** <li>  SQLITE_MUTEX_STATIC_LRU
** <li>  SQLITE_MUTEX_STATIC_LRU2
** </ul>
**
** The first two constants cause sqlite3_mutex_alloc() to create
** a new mutex.  The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
** is used but not necessarily so when SQLITE_MUTEX_FAST is used.
** The mutex implementation does not need to make a distinction
** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
** not want to.  But SQLite will only request a recursive mutex in
** cases where it really needs one.  If a faster non-recursive mutex
** implementation is available on the host platform, the mutex subsystem
** might return such a mutex in response to SQLITE_MUTEX_FAST.
**
** The other allowed parameters to sqlite3_mutex_alloc() each return
** a pointer to a static preexisting mutex.  Six static mutexes are
** used by the current version of SQLite.  Future versions of SQLite
** may add additional static mutexes.  Static mutexes are for internal
** use by SQLite only.  Applications that use SQLite mutexes should
** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
** SQLITE_MUTEX_RECURSIVE.
**
** Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
** returns a different mutex on every call.  But for the static
** mutex types, the same mutex is returned on every call that has
** the same type number.

/*
** A Note About Memory Allocation:
**
** This driver uses malloc()/free() directly rather than going through
** the SQLite-wrappers sqlite3_malloc()/sqlite3_free().  Those wrappers
** are designed for use on embedded systems where memory is scarce and
** malloc failures happen frequently.  OS/2 does not typically run on
** embedded systems, and when it does the developers normally have bigger
** problems to worry about than running out of memory.  So there is not
** a compelling need to use the wrappers.
**
** But there is a good reason to not use the wrappers.  If we use the
** wrappers then we will get simulated malloc() failures within this
** driver.  And that causes all kinds of problems for our tests.  We
** could enhance SQLite to deal with simulated malloc failures within
** the OS driver, but the code to deal with those failure would not
** be exercised on Linux (which does not need to malloc() in the driver)
** and so we would have difficulty writing coverage tests for that
** code.  Better to leave the code out, we think.
**
** The point of this discussion is as follows:  When creating a new
** OS layer for an embedded system, if you use this file as an example,
** avoid the use of malloc()/free().  Those routines work ok on OS/2
** desktops but not so well in embedded systems.

** describing the last IO error to have occurred within the calling
** thread.

** is zero if the error message fits in the buffer, or non-zero
** otherwise (if the message was truncated). If non-zero is returned,
** then it is not necessary to include the nul-terminator character
** in the output buffer.
**
** Not supplying an error message will have no adverse effect
** on SQLite. It is fine to have an implementation that never
** returns an error message:

** connection to it closes.  Because the wal-index is transient, it can

** Hence, unlike the database and WAL file formats which store all values
** as big endian, the wal-index can store multi-byte values in the native
** byte order of the host computer.
**
** The purpose of the wal-index is to answer this question quickly:  Given
** a page number P and a maximum frame index M, return the index of the 
** a page number P, return the index of the last frame for page P in the WAL,
** last frame in the wal before frame M for page P in the WAL, or return
** NULL if there are no frames for page P in the WAL prior to M.
** or return NULL if there are no frames for page P in the WAL.
**
** The wal-index consists of a header region, followed by an one or
** more index blocks.  
**
** The wal-index header contains the total number of frames within the WAL
** in the the mxFrame field.

/* During the search for the best function definition, this procedure
** is called to test how well the function passed as the first argument
** matches the request for a function with nArg arguments in a system
** that uses encoding enc. The value returned indicates how well the
** request is matched. A higher value indicates a better match.
**
** If nArg is -1 that means to only return a match (non-zero) if p->nArg
** is also -1.  In other words, we are searching for a function that
** takes a variable number of arguments.
**
** If nArg is -2 that means that we are searching for any function 
** regardless of the number of arguments it uses, so return a positive
** match score for any
**
** The returned value is always between 0 and 6, as follows:
**
** 0: Not a match.
** 1: UTF8/16 conversion required and function takes any number of arguments.
** 2: UTF16 byte order change required and function takes any number of args.
** 3: encoding matches and function takes any number of arguments
** 0: Not a match, or if nArg<0 and the function is has no implementation.
** 1: A variable arguments function that prefers UTF-8 when a UTF-16
**    encoding is requested, or vice versa.
** 2: A variable arguments function that uses UTF-16BE when UTF-16LE is
**    requested, or vice versa.
** 3: A variable arguments function using the same text encoding.
** 4: A function with the exact number of arguments requested that
**    prefers UTF-8 when a UTF-16 encoding is requested, or vice versa.
** 5: A function with the exact number of arguments requested that
** 4: UTF8/16 conversion required - argument count matches exactly
** 5: UTF16 byte order conversion required - argument count matches exactly
** 6: Perfect match:  encoding and argument count match exactly.
**    prefers UTF-16LE when UTF-16BE is requested, or vice versa.
** 6: An exact match.
**
** If nArg==(-2) then any function with a non-null xStep or xFunc is
** a perfect match and any function with both xStep and xFunc NULL is

/*
    The goal of this version of close is different than that of sqlite3_close(), and is designed to lend itself better to .NET's non-deterministic finalizers and
    the GC thread.  SQLite will not close a database if statements are open on it -- but for our purposes, we'd rather finalize all active statements
    and forcibly close the database.  The reason is simple -- a lot of people don't Dispose() of their objects correctly and let the garbage collector
    do it.  This leads to unexpected behavior when a user thinks they've closed a database, but it's still open because not all the statements have
    hit the GC yet.

    So, here we have a problem ... .NET has a pointer to any number of sqlite3_stmt objects.  We can't call sqlite3_finalize() on these because
    their memory is freed and can be used for something else.  The GC thread could potentially try and call finalize again on the statement after
    that memory was deallocated.  BAD.  So, what we need to do is make a copy of each statement, and call finalize() on the copy -- so that the original
    statement's memory is preserved, and marked as BAD, but we can still manage to finalize everything and forcibly close the database.  Later when the 
    GC gets around to calling finalize_interop() on the "bad" statement, we detect that and finish deallocating the pointer.

#       remaining elements in each list.  Here is an example:
#
#       1. First, the archive file name has the patch level removed from it.
#          Next, it is mapped to the name of the array containing the file
#          lists via the first element of the corresponding list.
#
#       [lindex $manifests(EagleCore.exe) 0] ==> eagle ==> eagle_manifests
#
#       2. Next, the remaining elements are used to query the named file lists
#          from the array discovered in the previous step.
#
#       [lrange $manifests(EagleCore.exe) 1 end] ==> core library
#
#       3. Finally, the final list of files for this archive file name is built
#          by combining all the file names in the file lists discovered in the
#          previous step.  Duplicate file names, if any, should be harmless.
#
#       $result == $eagle_manifests(core) UNION $eagle_manifests(library)

<p>
</p>

<h2><b>Version History</b></h2>

<p>
    <b>1.0.82.0 - September XX, 2012</b>
</p>
<ul>
    <li>Updated to <a href="http://www.sqlite.org/src/info/trunk">SQLite 3.7.14</a>.</li>
    <li>The <a href="http://nuget.org/packages/System.Data.SQLite">primary NuGet package</a> now supports x86 / x64 and the .NET Framework 2.0 / 4.0 (i.e. in a single package).</li>
    <li>Fix the database cleanup ordering in the tests for ticket [343d392b51].</li>
    <li>Add support for the sqlite3_close_v2 function from the SQLite core library.</li>
    <li>Add support for <a href="http://www.sqlite.org/uri.html">URI file names</a> via the new FullUri connection string property.</li>
    <li>Improve support for the standard SQLite core library in the LINQ assembly and the test suite.</li>
    <li>Add SetMemoryStatus static method to the SQLiteConnection class.</li>
    <li>Improve threaded handling of the delegate used by the SQLiteLog class.</li>
    <li>Add define constants to support enabling or disabling individual groups of trace statements.</li>
</ul>
<p>
    <b>1.0.81.0 - May 27, 2012</b>
</p>
<ul>
    <li>Updated to <a href="http://www.sqlite.org/releaselog/3_7_12_1.html">SQLite 3.7.12.1</a>.</li>
    <li>Support compiling the interop assembly without support for the custom extension functions and the CryptoAPI based codec.</li>
    <li>Add DefineConstants property to the SQLiteConnection class to return the list of define constants used when compiling the core managed assembly.</li>
    <li>Add release archive verification tool to the release automation.</li>
    <li>Fix NullReferenceException when calling the SQLiteDataAdapter.FillSchema method on a query that returns multiple result sets. Fix for [3aa50d8413].</li>
    <li>Fix subtle race condition between threads fetching connection handles from the connection pool any garbage collection (GC) threads that may be running. Fix for [996d13cd87].</li>
    <li>Add missing call to SetTimeout in the SQLite3_UTF16.Open method.</li>
    <li>Add checks to prevent the SQLiteConnectionPool.Remove method from returning any connection handles that are closed or invalid.</li>
    <li>Modify static SQLiteBase helper methods to prevent them from passing IntPtr.Zero to the SQLite native library.</li>
    <li>Remove static locks from the static helper methods in the SQLiteBase class, replacing them with a lock on the connection handle instance being operated upon.</li>
    <li>Revise CriticalHandle derived classes to make them more thread-safe.</li>
    <li>Add connection pool related diagnostic messages when compiled with the DEBUG define constant.</li>
    <li>Add PoolCount property to the SQLiteConnection class to return the number of pool entries for the file name associated with the connection.</li>
    <li>Rename internal SQLiteLastError methods to GetLastError.</li>
    <li>Add assembly file test constraints to all tests that execute the &quot;test.exe&quot; or &quot;testlinq.exe&quot; files.</li>
</ul>
<p>
    <b>1.0.80.0 - April 1, 2012</b>
    <b>1.0.80.0 - April XX, 2012</b>
</p>
<ul>
    <li>Updated to <a href="http://www.sqlite.org/releaselog/3_7_11.html">SQLite 3.7.11</a>.</li>
    <li>In the SQLiteFunction class, when calling user-provided methods from a delegate called by native code, avoid throwing exceptions, optionally tracing the caught exceptions. Fix for [8a426d12eb].</li>
    <li>Add Visual Studio 2005 support to all the applicable solution/project files, their associated supporting files, and the test suite.</li>
    <li>Add Visual Studio 2005 support to the redesigned designer support installer.</li>
    <li>Add experimental support for &quot;pre-loading&quot; the native SQLite library based on the processor architecture of the current process.  This feature is now enabled by default at compile-time.</li>
    <li>Add support for the native <a href="http://www.sqlite.org/backup.html">SQLite Online Backup API</a>. Fix for [c71846ed57].</li>
    <li>Acquire and hold a static data lock while checking if the native SQLite library has been initialized to prevent a subtle race condition that can result in superfluous error messages. Fix for [72905c9a77].</li>
    <li>Support tracing of all parameter binding activity and use the connection flags to control what is traced.</li>
    <li>When converting a DateTime instance of an &quot;Unspecified&quot; kind to a string, use the same kind as the connection, if available.</li>
    <li>Add overload of the SQLiteDataReader.GetValues method that returns a NameValueCollection.</li>
    <li>Add static ToUnixEpoch method to the SQLiteConvert class to convert a DateTime value to the number of whole seconds since the Unix epoch.</li>
    <li>In the implicit conversion operators (to IntPtr) for both the SQLiteConnectionHandle and SQLiteStatementHandle classes, return IntPtr.Zero if the instance being converted is null.</li>
    <li>Write warning message to the active trace listeners (for the Debug build configuration only) if a column type or type name cannot be mapped properly. See [4bbf851fa5].</li>
    <li>Write warning message to the active trace listners (for the Debug build configuration only) if a column type or type name cannot be mapped properly. See [4bbf851fa5].</li>
    <li>When tracing SQL statements to be prepared, bypass the internal length limit of the sqlite3_log function by using the SQLiteLog class directly instead. Also, detect null and/or empty strings and emit a special message in that case.</li>
    <li>For the setup, the Visual Studio task should only be initially checked if the GAC task is available and vice-versa.</li>
    <li>Improve compatibility with custom command processors by using __ECHO instead of _ECHO in batch tools.</li>
    <li>Add OpenAndReturn method to the SQLiteConnection class to open a connection and return it.</li>
    <li>Add missing CheckDisposed calls to the SQLiteConnection class.</li>
    <li>Add missing throw statement to the SQLiteConnection class.</li>
    <li>Make sure the interop project uses /fp:precise for Windows CE.</li>

  contains the actual references to the C# source code files.  Unfortunately,
  due to limitations on how Visual Studio reads and interprets MSBuild files at
  design-time, the C# source code files do not show up in the Solution Explorer
  window.  This limitation is largely cosmetic and does <b>not</b> impact the
  correctness of the build process itself, whether in Visual Studio or when
  using MSBuild on the command line.

</p>

<p>
  When compiling and running a solution from within Visual Studio that uses the
  System.Data.SQLite project (including the test project), it is very important
  to select the correct build configuration and platform.  First, managed
  applications to be debugged inside Visual Studio cannot use the mixed-mode
  assembly (i.e. because it is always compiled to the platform-specific build
  output directory).  This is necessary to properly support building binaries
  for multiple platforms using the same source project files.  Therefore, only
  the &quot;DebugNativeOnly&quot; or &quot;ReleaseNativeOnly&quot; build
  configurations should be selected when running a managed application from
  inside Visual Studio that relies upon the System.Data.SQLite assembly.  These
  build configurations contain a custom post-build step that copies the required
  native assembly to the managed output directory (i.e. to enable running the
  managed binaries in-place).  However, this post-build step will only be
  performed if the selected platform matches that of the operating system (e.g.
  &quot;Win32&quot; for 32-bit Windows and &quot;x64&quot; for 64-bit Windows).
  Therefore, it is good practice to double-check the selected build platform
  against the operating system prior to attempting to run a managed project in
  the solution.
