 WINDOWS BUILD
 =============

-On Windows this build is known to work on Cygwin and some Msys2
-environments. We do not currently support Microsoft makefiles for
-native Windows builds.
+The recommended method to build extensions under windows is to use the
+Msys + Mingw build process. This provides a Unix-style build while
+generating native Windows binaries. Using the Msys + Mingw build tools
+means that you can use the same configure script as per the Unix build
+to create a Makefile. See the tcl/win/README file for the URL of
+the Msys + Mingw download.
+
+If you have VC++ then you may wish to use the files in the win
+subdirectory and build the extension using just VC++. These files have
+been designed to be as generic as possible but will require some
+additional maintenance by the project developer to synchronise with
+the TEA configure.in and Makefile.in files. Instructions for using the
+VC++ makefile are written in the first part of the Makefile.vc
+file.

-### `--debug` flag

 Autosetup reserves the flag name **`--debug`** for its own purposes,
 and its own special handling of `--enable-...` flags makes `--debug`
-an alias for `--enable-debug`. As this project has a long history of

-Branch-specific Customization
-========================================================================
-
-Certain vendor-specific branches require slight configure script
-customization. Rather than editing `sqlite-config.tcl` for this,
-which frequently leads to merge conflicts, the following approach
-is recommended:
-
-In the vendor-specific branch, create a file named
-`autosetup/sqlite-custom.tcl`.
-
-That file should contain the following content...
-
-If flag customization is required, add:
-
->
-```
-proc sqlite-custom-flags {} {
-  # If any existing --flags require different default values
-  # then call:
-  options-defaults {
-    flag-name new-default-value
-    ...
-  }
-  # ^^^ That will replace the default value but will not update
-  # the --help text, which may lead to some confusion:
-  # https://github.com/msteveb/autosetup/issues/77
-
-  return {
-   {*} {
-     new-flag-name => {Help text}
-     ...
-   }
-  }; #see below
-}
-```
-
-That function must return either an empty string or a list in the form
-used internally by [sqlite-config.tcl][]'s `sqlite-configure`.
-
-Next, define:
-
->
-```
-proc sqlite-custom-handle-flags {} {
-  ... do any custom flag handling here ...
-}
-```
-
-That function, if defined, will be called relatively late in the
-configure process, before any filtered files are generated but after
-all other significant processing.

-## Linking Against ZLIB
-
-Some feature (such as zip-file support in the CLI) require the ZLIB
-compression library.  That library is more or less universally available
-on unix platforms, but is seldom provided on Windows.  You will probably
-need to provide it yourself.  Here the the steps needed:
-
-  1.  Download the zlib-1.3.1.tar.gz tarball (or a similar version).
-      Unpack the tarball sources.  You can put them wherever you like.
-      For the purposes of this document, let's assume you put the source
-      tree in c:\\zlib-64.  Note:  If you are building for both x64 and
-      x86, you will need separate builds of ZLIB for each, thus separate
-      build directories.
-
-  2.  Before building SQLite (as described above) first make these
-      environment changes.  The lead-programmer for SQLite (who writes
-      these words) has BAT files named "env-x64.bat" and "env-x32.bat"
-      and "env-arm64.bat" that make these changes, and he runs those
-      BAT file whenever he starts a new shell.  These are the settings
-      needed:
-      <blockquote>
-         set USE_ZLIB=1<br>
-         set BUILD_ZLIB=0<br>
-         set ZLIBDIR=c:\\zlib-64
-      </blockquote>
-
-  3.  Because the settings in step 2 specify "BUILD_ZLIB=0", you will need
-      to build the library at least once.  I recommand:
-      <blockquote>
-         make clean sqlite3.exe BUILD_ZLIB=1
-      </blockquote>
-
-  4.  After making the environment changes specified in steps 1 through 3
-      above, you then build and test SQLite as you normally would.  The
-      environment variable changes will cause ZLIB to be linked automatically.

+Shared-Schema Mode Notes
+========================
+
+The [reuse-schema](/timeline?r=reuse-schema) branch contains changes 
+to allow SQLite connections to share schemas
+between database connections within the same process in order to save memory.
+Schemas may be shared between multiple databases attached to the same or
+distinct connection handles.
+
+Compile with -DSQLITE\_ENABLE\_SHARED\_SCHEMA in order to enable the
+shared-schema enhancement.  Enabling the shared-schema enhancement causes
+approximately a 0.1% increase in CPU cycles consumed and about a 3000-byte
+increase in the size of the library, even if shared-schema is never used.
+
+Assuming the compile-time requirements are satisfied, the shared-schema
+feature is engaged by opening the database connection using the
+sqlite3&#95;open&#95;v2() API with the SQLITE&#95;OPEN&#95;SHARED&#95;SCHEMA
+flag specified.  The main database and any attached databases will then share
+an in-memory Schema object with any other database opened within the process
+for which: 
+
+  * the contents of the sqlite&#95;master table, including all object names,
+    SQL statements and root pages are identical, and
+  * have the same values for the schema-cookie.
+
+Temp databases (those populated with "CREATE TEMP TABLE" and similar
+statements) never share schemas.
+
+Connections opened with the SQLITE&#95;OPEN&#95;SHARED&#95;SCHEMA flag
+specified may not modify any database schema except that belonging to the
+temp database in anyway. This includes creating or dropping database 
+objects, vacuuming the database, or running ANALYZE when the
+sqlite&#95;stat\[14\] tables do not exist.
+
+For SQLITE&#95;OPEN&#95;SHARED&#95;SCHEMA connections, the
+SQLITE&#95;DBSTATUS&#95;SCHEMA&#95;USED sqlite3&#95;db&#95;status() verb
+distributes the memory used for a shared schema object evenly between all
+database connections that share it.
+
+## The ".shared-schema" Command
+
+The shell tool on this branch contains a special dot-command to help with
+managing databases. The ".shared-schema" dot-command can be used to test
+whether or not two databases are similar enough to share in-memory schemas,
+and to fix minor problems that prevent them from doing so. To test if
+two or more database are compatible, one database is opened directly using 
+the shell tool and the following command issued:
+
+        .shared-schema check <database-1> [<database-2>]...
+
+where &lt;database-1&gt; etc. are replaced with the names of database files
+on disk. For each database specified on the command line, a single line of
+output is produced. If the database can share an in-memory schema with the
+main database opened by the shell tool, the output is of the form:
+
+        <database> is compatible
+
+Otherwise, if the database cannot share a schema with the main db, the output
+is of the form:
+
+        <database> is NOT compatible (<reason>)
+
+where &lt;reason&gt; indicates the cause of the incompatibility. &lt;reason&gt;
+is always one of the following.
+
+<ul>
+  <li> <b>objects</b> - the databases contain a different set schema objects
+  (tables, indexes, views and triggers).
+
+  <li> <b>SQL</b> - the databases contain the same set of objects, but the SQL
+  statements used to create them were not the same.
+
+  <li> <b>root pages</b> - the databases contain the same set of objects created
+  by the same SQL statements, but the root pages are not the same.
+
+  <li> <b>order of sqlite&#95;master rows</b> - the databases contain the same
+  set of objects created by the same SQL statements with the same root pages,
+  but the order of the rows in the sqlite&#95;master tables are different.
+
+  <li> <b>schema cookie</b> - the database schemas are compatible, but the 
+  schema cookie values ("PRAGMA schema&#95;version") are different.
+</ul>
+
+The final three problems in the list above can be fixed using the
+.shared-schema command. To modify such a database so that it can share a 
+schema with the main database, the following shell command is used:
+
+        .shared-schema fix <database-1> [<database-2>]...
+
+If a database can be modified so that it may share a schema with the main
+database opened by the shell tool, output is as follows:
+
+        Fixing <database>... <database> is compatible
+
+If a database does not require modification, or cannot be modified such that
+it can share a schema with the main database, the output of "fix" is identical
+to that of the "check" command.
+
+## Implementation Notes
+
+A single Schema object is never used by more than one database simultaneously,
+regardless of whether or not those databases are attached to the same or
+different database handles. Instead, a pool of schema objects is maintained 
+for each unique sqlite&#95;master-contents/schema-cookie combination
+opened within the process. Each time database schemas are required by a
+connection, for example as part of an sqlite3&#95;prepare\*(),
+sqlite3&#95;blob&#95;open() or sqlite3&#95;blob&#95;open() call, it obtains
+the minimum number of schemas required from the various schema-pools, returning
+them at the end of the call. This means that a single schema-pool only ever
+contains more than one copy of the schema if:
+
+  * Two threads require schemas from the same pool at the same time, or
+  * A single sqlite3&#95;prepare\*() call requires schemas for two or more
+    attached databases that use the same schema-pool.
+
+The size of a schema-pool never shrinks. Each schema pool always maintains 
+a number of schema objects equal to the highwater mark of schema objects
+simultaneously required by clients.
+
+This approach is preferred to allowing multiple databases to use the same
+Schema object simultaneously for three reasons:
+
+  * The Schema object is not completely read-only. For example, the 
+    Index.zIdxAff string is allocated lazily.
+  * Throughout the statement compiler, SQLite uses variables like 
+    Table.pSchema and Index.pSchema with the sqlite3SchemaToIndex() routine
+    in order to determine which attached database a Table or Index object
+    resides in. This mechanism does not work if the same Schema may be
+    used by two or more attached databases.
+  * It may be easier to modify this approach in order to allow
+    SQLITE&#95;OPEN&#95;SHARED&#95;SCHEMA connections to modify database
+    schemas, should that be required.
+
+SQLITE&#95;OPEN&#95;SHARED&#95;SCHEMA connections do not store their
+virtual-table handles in the Table.pVTable list of each table. This would not
+work, as (a) there is no guarantee that a connection will be assigned the same
+Schema object each time it requests one from a schema-pool and (b) a single
+Schema (and therefore Table) object may correspond to tables in two or more
+databases attached to a single connection. Instead, all virtual-table handles
+associated with a single database are stored in a linked-list headed at
+Db.pVTable.

 # 1. Overview

-The testrunner.tcl program is a Tcl script used to run multiple SQLite
-tests in parallel, thus reducing testing time on multi-core machines.
-The testrunner.tcl supports running tests that based on `testfixture`,
-`sqlite3`, and `fuzzcheck`.
+testrunner.tcl is a Tcl script used to run multiple SQLite tests using 
+multiple jobs. It supports the following types of tests:

-<a name="runtr"></a>
-## 1.1 Running testrunner.tcl
+  *  Tcl test scripts.

-The testrunner.tcl script is located in the "test" subdirectory of the
-SQLite source tree.  So if your shell is current positioned at the top
-of the source tree, you would normally run the script using the command:
-"<tt>test/testrunner.tcl</tt>".  On Windows, you have to specify the
-`tclsh` interpreter command first, like this:
-"<tt>tclsh&nbsp;test/testrunner.tcl</tt>".
+  *  Tests run with `make` commands.  Examples:
+      -  `make mdevtest`
+      -  `make releasetest`
+      -  `make sdevtest`
+      -  `make testrunner`

-In this document, we will assume that you are on a unix-like OS
-(not on Windows) and that your current directory is the root
-of the SQLite source tree, and so all invocations of the testrunner.tcl
-script will be of the form "<tt>test/testrunner.tcl</tt>".  If you
-are in a different directory, then make appropriate adjustments to
-the path.  On Windows, add the "<tt>tclsh</tt>" interpreter command
-up front.

-The standard Makefiles for SQLite include targets that invoke

 # 2. Binary Tests

 The commands described in this section all run various combinations of the Tcl
-test scripts using whatever `testfixture` binary (and maybe also the `sqlite3`
-binary, depending on the test) that is found in the directory from which
-testrunner.tcl is launched.  So typically, one must first run something
-like "`make testfixture sqlite3`" before launching binary tests.  In other
-words, testrunner.tcl does not automatically build the binaries under test

+test scripts using the `testfixture` binary used to run the testrunner.tcl
+script (i.e. they do not invoke the compiler to build new binaries, or the
+`make` command to run tests that are not Tcl scripts). The procedure to run
+these tests is therefore:
+
+  1. Build the "testfixture" (or "testfixture.exe" for windows) binary using
+     whatever method seems convenient.
+
+  2. Test the binary built in step 1 by running testrunner.tcl with it,

-## 3.4 External Fuzzcheck Databases
-
-Testrunner.tcl will also run fuzzcheck against an external (out of tree)
-database, for example fuzzcheck databases generated by dbsqlfuzz.  To do
-this, simply add the "`--fuzzdb` *FILENAME*" command-line option or set 
-the FUZZDB environment variable to the name of the external
-database.  For large external databases, testrunner.tcl will automatically use
-the "`--slice`" command-line option of fuzzcheck to divide the work up into
-multiple jobs, to increase parallelism.
-
-Thus, for example, to run a full releasetest including an external
-dbsqlfuzz database, run a command like one of these:
-
-```
-  test/testrunner.tcl releasetest --fuzzdb ../fuzz/20250415.db

-  nmake /f Makefile.msc FUZZDB=../fuzz/20250415.db releasetest

-The patternlist option to testrunner.tcl will match against fuzzcheck
-databases.  So if you want to run *only* tests involving the external
-database, you can use a command something like this:
