Enhance the JSON parser cache such that it is able to extract lines from

the cache and use them for writing, though they then have to be evicted from the cache. This was an experiment in trying to reduce the amount of parsing needed for a big UPDATE, but it does not seem to help any. Retained for reference only.

-## Compiling for Windows Using MSVC
+## Using MSVC for Windows systems

 On Windows, all applicable build products can be compiled with MSVC.
-You will also need a working installation of TCL.
-See the [compile-for-windows.md](doc/compile-for-windows.md) document for
-additional information about how to install MSVC and TCL and configure your
-build environment.
+First open the command prompt window associated with the desired compiler
+version (e.g. "Developer Command Prompt for VS2013").  Next, use NMAKE
+with the provided "Makefile.msc" to build one of the supported targets.

-If you want to run tests, you need to let SQLite know the location of your
-TCL library, using a command like this:
+For example, from the parent directory of the source subtree named "sqlite":

-        set TCLDIR=c:\Tcl
+        mkdir bld
+        cd bld
+        nmake /f ..\sqlite\Makefile.msc TOP=..\sqlite
+        nmake /f ..\sqlite\Makefile.msc sqlite3.c TOP=..\sqlite
+        nmake /f ..\sqlite\Makefile.msc sqlite3.dll TOP=..\sqlite
+        nmake /f ..\sqlite\Makefile.msc sqlite3.exe TOP=..\sqlite
+        nmake /f ..\sqlite\Makefile.msc test TOP=..\sqlite

-SQLite uses "tclsh.exe" as part of the build process, and so that utility
-program will need to be somewhere on your %PATH%.  The finished SQLite library
-does not contain any TCL code, but it does use TCL to help with the build process
-and to run tests.
+There are several build options that can be set via the NMAKE command
+line.  For example, to build for WinRT, simply add "FOR_WINRT=1" argument
+to the "sqlite3.dll" command line above.  When debugging into the SQLite
+code, adding the "DEBUG=1" argument to one of the above command lines is
+recommended.

-Build using Makefile.msc.  Example:
-
-        nmake /f Makefile.msc
-        nmake /f Makefile.msc sqlite3.c
-        nmake /f Makefile.msc devtest
-        nmake /f Makefile.msc releasetest
- 
-There are many other makefile targets.  See comments in Makefile.msc for
-details.
+SQLite does not require [Tcl](http://www.tcl.tk/) to run, but a Tcl installation
+is required by the makefiles (including those for MSVC).  SQLite contains
+a lot of generated code and Tcl is used to do much of that code generation.

-# Notes On Compiling SQLite On Windows 11
-
-Here are step-by-step instructions on how to build SQLite from
-canonical source on a new Windows 11 PC, as of 2023-08-16:
-
-  1.  Install Microsoft Visual Studio. The free "community edition" 
-      will work fine.  Do a standard install for C++ development.
-      SQLite only needs the
-      "cl" compiler and the "nmake" build tool.
-
-  2.  Under the "Start" menu, find "All Apps" then go to "Visual Studio 20XX"
-      and find "x64 Native Tools Command Prompt for VS 20XX".  Pin that
-      application to your task bar, as you will use it a lot.  Bring up
-      an instance of this command prompt and do all of the subsequent steps
-      in that "x64 Native Tools" command prompt.  (Or use "x86" if you want
-      a 32-bit build.)  The subsequent steps will not work in a vanilla
-      DOS prompt.  Nor will they work in PowerShell.
-
-  3.  Install TCL development libraries.  This note assumes that you wil
-      install the TCL development libraries in the "`c:\Tcl`" directory.
-      Make adjustments
-      if you want TCL installed somewhere else.  SQLite needs both the
-      "tclsh.exe" command-line tool as part of the build process, and
-      the "tcl86.lib" library in order to run tests.  You will need
-      TCL version 8.6 or later.
-      <ol type="a">
-      <li>Get the TCL source archive, perhaps from
-      [https://www.tcl.tk/software/tcltk/download.html](https://www.tcl.tk/software/tcltk/download.html).
-      <li>Untar or unzip the source archive.  CD into the "win/" subfolder
-          of the source tree.
-      <li>Run: `nmake /f makefile.vc release`
-      <li>Run: `nmake /f makefile.vc INSTALLDIR=c:\Tcl install`
-      <li>CD to `c:\Tcl\lib`.  In that subfolder make a copy of the
-          "`tcl86t.lib`" file to the alternative name "`tcl86.lib`"
-          (omitting the second 't').  Leave the copy in the same directory
-          as the original.
-      <li>CD to `c:\Tcl\bin`.  Make a copy of the "`tclsh86t.exe`"
-          file into "`tclsh.exe`" (without the "86t") in the same directory.
-      <li>Add `c:\Tcl\bin` to your %PATH%.  To do this, go to Settings
-          and search for "path".  Select "edit environment variables for
-          your account" and modify your default PATH accordingly.
-          You will need to close and reopen your command prompts after
-          making this change.
-      </ol>
-
-  4.  Download the SQLite source tree and unpack it. CD into the
-      toplevel directory of the source tree.
-
-  5.  Set the TCLDIR environment variable to point to your TCL installation.
-      Like this:
-      <ul>
-      <li> `set TCLDIR=c:\Tcl`
-      </ul>
-
-  6.  Run the "`Makefile.msc`" makefile with an appropriate target.
-      Examples:
-      <ul>
-      <li>  `nmake /f makefile.msc`
-      <li>  `nmake /f makefile.msc sqlite3.c`
-      <li>  `nmake /f makefile.msc devtest`
-      <li>  `nmake /f makefile.msc releasetest`
-      </ul>
-
-## 32-bit Builds
-
-Doing a 32-bit build is just like doing a 64-bit build with the
-following minor changes:
-
-  1.  Use the "x86 Native Tools Command Prompt" instead of
-      "x64 Native Tools Command Prompt".  "**x86**" instead of "**x64**".
-
-  2.  Use a different installation directory for TCL.
-      The recommended directory is `c:\tcl32`.  Thus you end up
-      with two TCL builds:
-      <ul>
-      <li> `c:\tcl` &larr;  64-bit (the default)
-      <li> `c:\tcl32` &larr;  32-bit
-      </ul>
-
-  3.  Ensure that `c:\tcl32\bin` comes before `c:\tcl\bin` on
-      your PATH environment variable.  You can achieve this using
-      a command like:
-      <ul>
-      <li>  `set PATH=c:\tcl32\bin;%PATH%`
-      </ul>

-SQLite3 via JNI
-========================================================================
-
-This directory houses a Java Native Interface (JNI) binding for the
-sqlite3 API. If you are reading this from the distribution ZIP file,
-links to resources in the canonical source tree will note work. The
-canonical copy of this file can be browsed at:
-
-  <https://sqlite.org/src/doc/trunk/ext/jni/README.md>
-
-Technical support is available in the forum:
-
-  <https://sqlite.org/forum>
-
-
-> **FOREWARNING:** this subproject is very much in development and
-  subject to any number of changes. Please do not rely on any
-  information about its API until this disclaimer is removed.
-
-Project goals/requirements:
-
- A [1-to-1(-ish) mapping of the C API](#1to1ish) to Java via JNI,
-  insofar as cross-language semantics allow for. A closely-related
-  goal is that [the C documentation](https://sqlite.org/c3ref/intro.html)
-  should be usable as-is, insofar as possible, for the JNI binding.
-
- Support Java as far back as version 8 (2014).
-
- Environment-independent. Should work everywhere both Java
-  and SQLite3 do.
-
- No 3rd-party dependencies beyond the JDK. That includes no
-  build-level dependencies for specific IDEs and toolchains.  We
-  welcome the addition of build files for arbitrary environments
-  insofar as they neither interfere with each other nor become
-  a maintenance burden for the sqlite developers.
-
-Non-goals:
-
- Creation of high-level OO wrapper APIs. Clients are free to create
-  them off of the C-style API.
-
-
-Significant TODOs
-========================================================================
-
- The initial beta release with version 3.43 has severe threading
-  limitations.  Namely, two threads cannot call into the JNI-bound API
-  at once. This limitation will be remove in a subsequent release.
-
-
-Building
-========================================================================
-
-The canonical builds assumes a Linux-like environment and requires:
-
- GNU Make
- A JDK supporting Java 8 or higher
- A modern C compiler. gcc and clang should both work.
-
-Put simply:
-
-```
-$ export JAVA_HOME=/path/to/jdk/root
-$ make
-$ make test
-$ make clean
-```
-
-<a id='1to1ish'></a>
-One-to-One(-ish) Mapping to C
-========================================================================
-
-This JNI binding aims to provide as close to a 1-to-1 experience with
-the C API as cross-language semantics allow. Exceptions are
-necessarily made where cross-language semantics do not allow a 1-to-1,
-and judiciously made where a 1-to-1 mapping would be unduly cumbersome
-to use in Java.
-
-Golden Rule: _Never_ Throw from Callbacks
------------------------------------------------------------------------
-
-JNI bindings which accept client-defined functions _must never throw
-exceptions_ unless _very explicitly documented_ as being
-throw-safe. Exceptions are generally reserved for higher-level
-bindings which are constructed to specifically deal with them and
-ensure that they do not leak C-level resources. Some of the JNI
-bindings are provided as Java functions which expect this rule to
-always hold.
-
-UTF-8(-ish)
------------------------------------------------------------------------
-
-SQLite internally uses UTF-8 encoding, whereas Java natively uses
-UTF-16.  Java JNI has routines for converting to and from UTF-8, _but_
-Java uses what its docs call "[modified UTF-8][modutf8]." Care must be
-taken when converting Java strings to UTF-8 to ensure that the proper
-conversion is performed. In short,
-`String.getBytes(StandardCharsets.UTF_8)` performs the proper
-conversion in Java, and there is no JNI C API for that conversion
-(JNI's `NewStringUTF()` returns MUTF-8).
-
-Known consequences and limitations of this discrepancy include:
-
- Names of databases, tables, and collations must not contain
-  characters which differ in MUTF-8 and UTF-8, or certain APIs will
-  mis-translate them on their way between languages. APIs which
-  transfer other client-side data to Java take extra care to
-  convert the data at the cost of performance.
-
-[modutf8]: https://docs.oracle.com/javase/8/docs/api/java/io/DataInput.html#modified-utf-8
-
-
-Unwieldy Constructs are Re-mapped
------------------------------------------------------------------------
-
-Some constructs, when modelled 1-to-1 from C to Java, are unduly
-clumsy to work with in Java because they try to shoehorn C's way of
-doing certain things into Java's wildly different ways. The following
-subsections cover those, starting with a verbose explanation and
-demonstration of where such changes are "really necessary"...
-
-### Custom Collations
-
-A prime example of where interface changes for Java are necessary for
-usability is [registration of a custom
-collation](https://sqlite.org/c3ref/create_collation.html):
-
-```
-// C:
-int sqlite3_create_collation(sqlite3 * db, const char * name, int eTextRep,
-                             void *pUserData,
-                             int (*xCompare)(void*,int,void const *,int,void const *));
-
-int sqlite3_create_collation_v2(sqlite3 * db, const char * name, int eTextRep,
-                                void *pUserData,
-                                int (*xCompare)(void*,int,void const *,int,void const *),
-                                void (*xDestroy)(void*));
-```
-
-The `pUserData` object is optional client-defined state for the
-`xCompare()` and/or `xDestroy()` callback functions, both of which are
-passed that object as their first argument. That data is passed around
-"externally" in C because that's how C models the world. If we were to
-bind that part as-is to Java, the result would be awkward to use (^Yes,
-we tried this.):
-
-```
-// Java:
-int sqlite3_create_collation(sqlite3 db, String name, int eTextRep,
-                             Object pUserData, xCompareType xCompare);
-
-int sqlite3_create_collation_v2(sqlite3 db, String name, int eTextRep,
-                                Object pUserData,
-                                xCompareType xCompare, xDestroyType xDestroy);
-```
-
-The awkwardness comes from (A) having two distinctly different objects
-for callbacks and (B) having their internal state provided separately,
-which is ill-fitting in Java. For the sake of usability, C APIs which
-follow that pattern use a slightly different Java interface:
-
-```
-int sqlite3_create_collation(sqlite3 db, String name, int eTextRep,
-                             Collation collation);
-```
-
-Where the `Collation` class has an abstract `xCompare()` method and
-no-op `xDestroy()` method which can be overridden if needed, leading to
-a much more Java-esque usage:
-
-```
-int rc = sqlite3_create_collation(db, "mycollation", SQLITE_UTF8, new Collation(){
-
-  // Required comparison function:
-  @Override public int xCompare(byte[] lhs, byte[] rhs){ ... }
-
-  // Optional finalizer function:
-  @Override public void xDestroy(){ ... }
-
-  // Optional local state:
-  private String localState1 =
-    "This is local state. There are many like it, but this one is mine.";
-  private MyStateType localState2 = new MyStateType();
-  ...
-});
-```
-
-Noting that:
-
- It is still possible to bind in call-scope-local state via closures,
-  if desired.
-
- No capabilities of the C API are lost or unduly obscured via the
-  above API reshaping, so power users need not make any compromises.
-
- In the specific example above, `sqlite3_create_collation_v2()`
-  becomes superfluous because the provided interface effectively
-  provides both the v1 and v2 interfaces, the difference being that
-  overriding the `xDestroy()` method effectively gives it v2
-  semantics.
-
-### User-defined SQL Functions (a.k.a. UDFs)
-
-The [`sqlite3_create_function()`](https://sqlite.org/c3ref/create_function.html)
-family of APIs make heavy use of function pointers to provide
-client-defined callbacks, necessitating interface changes in the JNI
-binding. The Java API has only one core function-registration function:
-
-```
-int sqlite3_create_function(sqlite3 db, String funcName, int nArgs,
-                            int encoding, SQLFunction func);
-```
-
-> Design question: does the encoding argument serve any purpose in JS?
-
-`SQLFunction` is not used directly, but is instead instantiated via
-one of its three subclasses:
-
- `SQLFunction.Scalar` implements simple scalar functions using but a
-  single callback.
- `SQLFunction.Aggregate` implements aggregate functions using two
-  callbacks.
- `SQLFunction.Window` implements window functions using four
-  callbacks.
-
-Search [`Tester1.java`](/file/ext/jni/src/org/sqlite/jni/Tester1.java) for
-`SQLFunction` for how it's used.
-
-Reminder: see the disclaimer at the top of this document regarding the
-in-flux nature of this API.

-
-     The 2nd argument to this function, if non-0, will be a native

-       passing it on, but there's no readily-available way to do that
-       without calling back into the db to peform the conversion
-       (which would lead to further tracing).
-
-     - SQLITE_TRACE_PROFILE: pNative is a sqlite3_stmt. pX is a Long

-# Specifications For A Rudimentary SQLite Test Script Interpreter
-
-## Overview
-
-The purpose of the Test Script Interpreter is to read and interpret
-script files that contain SQL commands and desired results.  The
-interpreter will check results and report an discrepencies found.
-
-The test script files are ASCII text files.  The filename always ends with
-".test".  Each script is evaluated independently; context does not carry
-forward from one script to the next.  So, for example, the --null command
-run in one test script does not cause any changes in the behavior of
-subsequent test scripts.  All open database connections are closed
-at the end of each test script.  All database files created by a test
-script are deleted when the script finishes.
-
-## Parsing Rules:
-
-  1.   The test script is read line by line, where a line is a sequence of
-       characters that runs up to the next '\\n' (0x0a) character or until
-       the end of the file.  There is never a need to read ahead past the
-       end of the current line.
-
-  2.   If any line contains the string " MODULE_NAME:" (with a space before
-       the initial "M") or "MIXED_MODULE_NAME:" then that test script is
-       incompatible with this spec.  Processing of the test script should
-       end immediately.  There is no need to read any more of the file.
-       In verbose mode, the interpreter might choose to emit an informational
-       messages saying that the test script was abandoned due to an
-       incompatible module type.
-
-  3.   If any line contains the string "SCRIPT_MODULE_NAME:" then the input
-       script is known to be of the correct type for this specification and
-       processing may continue.  The "MODULE_NAME" checking in steps 2 and 3
-       may optionally be discontinued after sighting a "SCRIPT_MODULE_NAME".
-
-  4.   If any line contains "REQUIRED_PROPERTIES:" and that substring is followed
-       by any non-whitespace text, then the script is not compatible with this
-       spec.  Processing should stop immediately.  In verbose mode, the
-       interpreter might choose to emit an information message saying that the
-       test script was abandoned due to unsupported requirement properties.
-
-  5.   If any line begins with the "\|" (0x7c) character, that indicates that
-       the input script is not compatible with this specification.  Processing
-       of the script should stop immediately.  In verbose mode, the interpreter
-       might choose to emit an informational message indicating that the
-       test script was abandoned because it contained "a dbtotxt format database
-       specification".
-
-  6.   Any line that begins with "#" is a C-preprocessor line.  The interpreter
-       described by this spec does not know how to deal with C-preprocessor lines.
-       Hence, processing should be abandoned.  In verbose mode, the interpreter
-       might emit an informational message similar to
-       "script NAME abandoned due to C-preprocessor line: ..."
-
-  7.   If a line begins with exactly two minus signs followed by a
-       lowercase letter, that is a command.  Process commands as described
-       below.
-
-  8.   All other lines should be accumulated into the "input buffer".
-       The various commands will have access to this input buffer.
-       Some commands will reset the buffer.
-
-## Initialization
-
-The initial state of the interpreter at the start of processing each script
-is as if the following command sequence had been run:
-
-> ~~~
--close all
--db 0
--new test.db
--null nil
-~~~
-
-In words, all database connections are closed except for connection 0 (the
-default) which is open on an empty database named "test.db".  The string
-"nil" is displayed for NULL column values.
-
-The only context carried forward after the evaluation of one test script
-into the evaluation of the next test script is the count of the number of
-tests run and the number of failures seen.
-
-## Commands:
-
-Each command looks like an SQL comment.  The command begins at the left
-margin (no leading space) and starts with exactly 2 minus signs ("-").
-The command name consists of lowercase letters and maybe a "-" or two.
-Some commands have arguments.
-The arguments are separated from the command name by one or more spaces.
-
-Commands have access to the input buffer and might reset the input buffer.
-The command can also optionally read (and consume) additional text from
-script that comes after the command.
-
-Unknown or unrecognized commands indicate that the script contains features
-that are not (yet) supported by this specification.  Processing of the
-script should terminate immediately.  When this happens and when the
-interpreter is in a "verbose" mode, the interpreter might choose to emit
-an informational message along the lines of "test script NAME abandoned
-due to unsupported command: --whatever".
-
-The initial implemention will only recognize a few commands.  Other
-commands may be added later.  The following is the initial set of
-commands:
-
-### The --testcase command
-
-Every test case starts with a --testcase command.  The --testcase
-command resets both the "input buffer" and the "result buffer".  The
-argument to the --testcase command is the name of the test case.  That
-test case name is used for logging and debugging and when printing
-errors. The input buffer is set to the body of the test case.
-
-### The --result command
-
-The --result command tries to execute the text in the input buffer as SQL.
-For each row of result coming out of this SQL, the text of that result is
-appended to the "result buffer".  If a result row contains multiple columns,
-the columns are processed from left to right.  For each column, text is
-appended to the result buffer according to the following rules:
-
-  *   If the result buffer already contains some text, append a space.
-      (In this way, all column values and all row values are separated from
-      each other by a single space.)
-
-  *   If sqlite3_column_text() returns NULL, then append "nil" - or
-      some other text that is specified by the --null command - and skip
-      all subsequent rules.
-
-  *   If sqlite3_column_text() is an empty string, append `{}` to the
-      result buffer and skip all subsequent rules.
-
-  *   If sqlite3_column_text() does not contain any special
-      characters, append it to the result buffer without any
-      formatting and skip all subsequent rules. Special characters are:
-      0x00 to 0x20 (inclusive), double-quote (0x22), backslash (0x5c),
-      curly braces (0x7b and 0x7d).
-
-  *   If sqlite3_column_text() does not contains curly braces, then put
-      the text inside of `{...}` and append it and skip all subsequent rules.
-
-  *   Append the text within double-quotes (`"..."`) and within the text
-      escape '"' and '\\' by prepending a single '\\' and escape any
-      control characters (characters less than 0x20) using octal notation:
-      '\\NNN'.
-
-If an error is encountered while running the SQL, then append the
-symbolic C-preprocessor name for the error
-code (ex: "SQLITE_CONSTRAINT") as if it were a column value.  Then append
-the error message text as if it where a column value.  Then stop processing.
-
-After the SQL text has been run, compare the content of the result buffer
-against the argument to the --result command and report a testing error if
-there are any differences.
-
-The --result command resets the input buffer, but it does not reset
-the result buffer.  This distinction does not matter for the --result
-command itself, but it is important for related commands like --glob
-and --notglob.  Sometimes test cases will contains a bunch of SQL
-followed by multiple --glob and/or --notglob statements.  All of the
-globs should be evaluted agains the result buffer correct, but the SQL
-should only be run once.  This is accomplished by resetting the input
-buffer but not the result buffer.
-
-### The --glob command
-
-The --glob command works just like --result except that the argument to
--glob is interpreted as a TEST-GLOB pattern and the results are compared
-using that glob pattern rather than using strcmp().  Other than that,
-the two operate the same.
-
-The TEST-GLOB pattern is slightly different for a standard GLOB:
-
-   *    The '*' character matches zero or more characters.
-
-   *    The '?' character matches any single character
-
-   *    The '[...]' character sequence machines a single character
-        in between the brackets.
-
-   *    The '#' character matches one or more digits  (This is the main
-        difference between standard unix-glob and TEST-GLOB.  unix-glob
-        does not have this feature.  It was added to because it comes
-        up a lot during SQLite testing.)
-
-### The --notglob command
-
-The --notglob command works just like --glob except that it reports an
-error if the GLOB does match, rather than if the GLOB does not matches.
-
-### The --oom command
-
-This command is to be used for out-of-memory testing.  It means that
-OOM errors should be simulated to ensure that SQLite is able to deal with
-them.  This command can be silently ignored for now.  We might add support
-for this later.
-
-### The --tableresult command
-
-The --tableresult command works like --glob except that the GLOB pattern
-to be matched is taken from subsequent lines of the input script up to
-the next --end.  Every span of one or more whitespace characters in this
-pattern text is collapsed into a single space (0x20).
-Leading and trailing whitespace are removed from the pattern.
-The --end that ends the GLOB pattern is not part of the GLOB pattern, but
-the --end is consumed from the script input.
-
-### The --new and --open commands
-
-The --new and --open commands cause a database file to be opened.
-The name of the file is the argument to the command.  The --new command
-opens an initially empty database (it deletes the file before opening it)
-whereas the --open command opens an existing database if it already
-exists.
-
-### The --db command
-
-The script interpreter can have up to 7 different SQLite database
-connections open at a time.  The --db command is used to switch between
-them.  The argument to --db is an integer between 0 and 6 that selects
-which database connection to use moving forward.
-
-### The --close command
-
-The --close command causes an existing database connection to close.
-This command is a no-op if the database connection is not currently
-open.  There can be up to 7 different database connections, numbered 0
-through 6.  The number of the database connection to close is an
-argument to the --close command, which will fail if an out-of-range
-value is provided.  Or if the argument to --close is "all" then all
-open database connections are closed. If passed no argument, the
-currently-active database is assumed.
-
-### The --null command
-
-The NULL command changes the text that is used to represent SQL NULL
-values in the result buffer.
-
-### The --run command
-
-The --run command executes text in the input buffer as if it where SQL.
-However, nothing is added to the result buffer.  Any output from the SQL
-is silently ignored. Errors in the SQL are silently ignored.
-
-The --run command normally executes the SQL in the current database
-connection.  However, if --run has an argument that is an integer between
-0 and 6 then the SQL is run in the alternative database connection specified
-by that argument.
-
-### The --json and --json-block commands
-
-The --json and --json-block commands work like --result and --tableresult,
-respectively.  The difference is that column values are appended to the
-result buffer literally, without ever enclosing the values in `{...}` or
-`"..."` and without escaping any characters in the column value and comparison
-is always an exact strcmp() not a GLOB.
-
-### The --print command
-
-The --print command emits both its arguments and its body (if any) to
-stdout, indenting each line of output.
-
-### The --column-names command
-
-The --column-names command requires 0 or 1 as an argument, to disable
-resp.  enable it, and modifies SQL execution to include column names
-in output. When this option is on, each column value emitted gets
-prefixed by its column name, with a single space between them.
