-# - Provide Makefile.msc, Makefile.linux-gcc, and any required similar
-# makefile stubs for environments where the configure script will not

-# - There are some lingering dependencies issues which cause a
-# re-configure to trigger more often than it should.  This is
-# especially a problem in parallel builds, which may launch multiple
-# re-configures in parallel.  GNU Make offers ways of controlling
-# that, but we're limited to POSIX Make compatibility here. The
-# automatic reconfigures are not too onerous, though, because they're
-# much, much faster than Autotools configure runs.

-# - Add target(s) to dump out specific vars, e.g. SQLITE_OPT, as
-# requested at https://sqlite.org/forum/forumpost/75cb3179216f8d86.

 # Maintenance reminders:
 #
-# - When using the X?=Y variable assignment formulation, please test
-#   the build with both GNU make and a POSIX make (e.g. BSD make,
-#   a.k.a. bmake). On at least one occassion, that formulation has led

+Maintaining Autosetup in the SQLite Tree

+Autosetup API Reference
+========================================================================
+
+The Autosetup API is quite extensive and can be read either in
+the [files in the `autosetup` dir](/dir/autosetup) or using:
+
+>
+```
+$ ./configure --reference | less
+```
+
+That will include any docs from any TCL files in the `./autosetup` dir
+which contain certain (simple) markup defined by autosetup.
+
+This project's own autosetup-related APIs are in [proj.tcl][] or
+[auto.def][].  The former contains helper APIs which are, more or
+less, portable across projects (that file is re-used as-is in other
+projects) and all have a `proj-` name prefix. The latter is the main
+configure script driver and contains related functions which are
+specific to this tree.
+
+
+<a name="apitips"></a>
+Autosetup API Tips
+========================================================================
+
+This section briefly covers only APIs which are frequently useful in
+day-to-day maintenance and might not be immediately recognized as such
+obvious from a casual perusal of [auto.def][]. The complete docs of
+those with `proj-` prefix can be found in [proj.tcl][]. The others are
+scattered around [the TCL files in ./autosetup](/dir/autosetup).
+
+In (mostly) alphabetical order:
+
+- **`file-isexec filename`**\  
+  Should be used in place of `[file executable]`, as it will also
+  check for `${filename}.exe` on Windows platforms. However, on such
+  platforms it also assumes that _any_ existing file is executable.
+
+- **`get-env VAR ?default?`**\  
+  Will fetch an "environment variable" from the first of either: (1) a
+  KEY=VALUE passed to the configure script or (2) the system's
+  environment variables. Not to be confused with `getenv`, which only
+  does the latter and is rarely, if ever, useful in this tree.
+  - **`proj-get-env VAR ?default?`**\  
+    Works like `get-env` but will, if that function finds no match,
+    look for a file named `./.env-$VAR` and, if found, return its
+    trimmed contents. This can be used, e.g., to set a developer's
+    local preferences for the default `CFLAGS`.
+
+- **`define-for-opt flag defineName ?checkingMsg? ?yesVal=1? ?noVal=0?`**\  
+  `[define $defineName]` to either `$yesVal` or `$noVal`, depending on
+  whether `--$flag` is truthy or not. `$checkingMsg` is a
+  human-readable description of the check being made, e.g. "enable foo?"
+  If no `checkingMsg` is provided, the operation is silent.\  
+  Potential TODO: change the final two args to `-yes` and `-no`
+  flags. They're rarely needed, though: search [auto.def][] for
+  `TSTRNNR_OPTS` for an example of where they are used.
+
+- **`proj-fatal msg`**\  
+  Emits `$msg` to stderr and exits with non-zero.
+
+- **`proj-if-opt-truthy flag thenScript ?elseScript?`**\  
+  Evals `thenScript` if the given `--flag` is truthy, else it
+  evals the optional `elseScript`.
+
+- **`proj-indented-notice ?-error? ?-notice? msg`**\  
+  Breaks its `msg` argument into lines, trims them, and emits them
+  with consistent indentation. Exactly how it emits depends on the
+  flags passed to it (or not), as covered in its docs. This will stick
+  out starkly from normal output and is intended to be used only for
+  important notices.
+
+- **`proj-opt-truthy flag`**\  
+  Returns 1 if `--flag`'s value is "truthy," i.e. one of (1, on,
+  enabled, yes, true).
+
+- **`proj-opt-was-provided FLAG`**\  
+  Returns 1 if `--FLAG` was explicitly provided to configure,
+  else 0. This distinction can be used to determine, e.g., whether
+  `--with-readline` was provided or whether we're searching for
+  readline by default. In the former case, failure to find it should
+  be treated as fatal, where in the latter case it's not.
+
+- **`proj-val-truthy value`**\  
+  Returns 1 if `$value` is "truthy," See `proj-opt-truthy` for the definition
+  of "truthy."
+
+- **`proj-warn msg`**\  
+  Emits `$msg` to stderr. Closely-related is autosetup's `user-notice`
+  (described below).
+
+- **`sqlite-add-feature-flag ?-shell? FLAG...`**\  
+  Adds the given feature flag to the CFLAGS which are specific to
+  building libsqlite3. It's intended to be passed one or more
+  `-DSQLITE_ENABLE_...`, or similar, flags. If the `-shell` flag is
+  used then it also passes its arguments to
+  `sqlite-add-shell-opt`. This is a no-op if `FLAG` is not provided or
+  is empty.
+
+- **`sqlite-add-shell-opt FLAG...`**\  
+  The shell-specific counterpart of `sqlite-add-feature-flag` which
+  only adds the given flag(s) to the CLI-shell-specific CFLAGS.
+
+- **`user-notice msg`**\  
+  Queues `$msg` to be sent to stderr, but does not emit it until
+  either `show-notices` is called or the next time autosetup would
+  output something (it internally calls `show-notices`). This can be
+  used to generate warnings between a "checking for..." message and
+  its resulting "yes/no/whatever" message in such a way as to not
+  spoil the layout of such messages.
+
+
+<a name="tclcompat"></a>
+Ensuring TCL Compatibility
+========================================================================
+
+It is important that any TCL files used by the configure process
+remain compatible with both [JimTCL][] and the canonical TCL. Though
+JimTCL has outstanding compatibility with canonical TCL, it does have
+a few corners with incompatibilities, e.g. regular expressions. If a
+script runs in JimTCL without using any JimTCL-specific features, then
+it's a certainty that it will run in canonical TCL as well. The
+opposite, however, is not _always_ the case.
+
+When [`./configure`](/file/configure) is run, it goes through a
+bootstrapping process to find a suitable TCL with which to run the
+autosetup framework. The first step involves [finding or building a
+TCL shell](/file/autosetup/autosetup-find-tclsh).  That will first
+search for an available `tclsh` (under several common names,
+e.g. `tclsh8.6`) before falling back to compiling the copy of
+`jimsh0.c` included in the source tree. i.e. it will prefer to use a
+system-installed TCL for running the configure script. Once it finds
+(or builds) a TCL shell, it then runs [a sanity test to ensure that
+the shell is suitable](/file/autosetup/autosetup-test-tclsh) before
+using it to run the main autosetup app.
+
+There are two simple ways to ensure that running of the configure
+process uses JimTCL instead of the canonical `tclsh`, and either
+approach provides equally high assurances about configure script
+compatibility across TCL implementations:
+
+1. Build on a system with no `tclsh` installed in the `$PATH`. In that
+   case, the configure process will fall back to building the in-tree
+   copy of JimTCL.
+
+2. Manually build `./jimsh0` in the top of the checkout with:\  
+   `cc -o jimsh0 autosetup/jimsh0.c`\  
+   With that in place, the configure script will prefer to use that
+   before looking for a system-level `tclsh`. Be aware, though, that
+   `make distclean` will remove that file.
+
+**Note that `jimsh0` is distinctly different from the `jimsh`** which
+gets built for code-generation purposes.  The latter requires
+non-default build flags to enable features which are
+platform-dependent, most notably to make its `[file normalize]` work.
+This means, for example, that the configure script and its utility
+APIs must not use `[file normalize]`, but autosetup provides a
+TCL-only implementation of `[file-normalize]` (note the dash) for
+portable use in the configure script.
+
+
+<a name="conventions"></a>
+Design Conventions
+========================================================================
+
+This section describes the motivations for the most glaring of the
+build's design decisions, in particular how they deviate from
+historical, or even widely-conventional, practices.
+
+Symbolic Names of Feature Flags
+------------------------------------------------------------------------
+
+Historically, the project's makefile has exclusively used
+`UPPER_UNDERSCORE` form for makefile variables. This build, however,
+primarily uses `X.y` format, where `X` is often a category label,
+e.g. `CFLAGS`, and `y` is the specific instance of that category,
+e.g. `CFLAGS.readline`.
+
+When the configure script exports flags for consumption by filtered
+files, e.g. [Makefile.in][] and the generated
+`sqlite_cfg.h`, it does so in the more conventional `X_Y` form because
+those flags get exported as as C `#define`s to `sqlite_cfg.h`, where
+dots are not permitted.
+
+The `X.y` convention is used in the makefiles primarily because the
+person who did the initial port finds that considerably easier on the
+eyes and fingers. In practice, the `X_Y` form of such exports is used
+exactly once in [Makefile.in][], where it's translated into into `X.y`
+form for consumption by [Makefile.in][] and [main.mk][]. For example:
+
+>
+```
+LDFLAGS.shobj = @SHOBJ_LDFLAGS@
+LDFLAGS.zlib = @LDFLAGS_ZLIB@
+LDFLAGS.math = @LDFLAGS_MATH@
+```
+
+(That first one is defined by autosetup, and thus applies "LDFLAGS" as
+the suffix rather than the prefix. Which is more legible is a matter
+of taste, for which there is no accounting.)
+
+
+Do Not Update Global Shared State
+------------------------------------------------------------------------
+
+In both the legacy Autotools-driven build and in common Autosetup
+usage, feature tests performed by the configure script may amend
+global flags such as `LIBS`, `LDFLAGS`, and `CFLAGS`[^as-cflags].  That's
+appropriate for a makefile which builds a single deliverable, but less
+so for makefiles which produce multiple deliverables. Drawbacks of
+that approach include:
+
+- It's unlikely that every single deliverable will require the same
+  core set of those flags.
+- It can be difficult to determine the origin of any given change to
+  that global state because those changes are hidden behind voodoo performed
+  outside the immediate visibility of the configure script's
+  maintainer.
+- It can force the maintainers of the configure script to place tests
+  in a specific order so that the resulting flags get applied at
+  the correct time and/or in the correct order.\  
+  (A real-life example: before the approach described below was taken
+  to collecting build-time flags, the test for `-rpath` had to come
+  _after_ the test for zlib because the results of the `-rpath` test
+  implicitly modified global state which broke the zlib feature
+  test. Because the feature tests no longer (intentionally) modify
+  shared global state, that is not an issue.)
+
+In this build, cases where feature tests modify global state in such a
+way that it may impact later feature tests are either (A) very
+intentionally defined to do so (e.g. the `--with-wasi-sdk` flag has
+invasive side-effects) or (B) are oversights (i.e. bugs).
+
+This tree's [configure script][auto.def], [utility APIs][proj.tcl],
+[Makefile.in][], and [main.mk][] therefore strive to separate the
+results of any given feature test into its own well-defined
+variables. For example:
+
+- The linker flags for zlib are exported from the configure script as
+  `LDFLAGS_ZLIB`, which [Makefile.in][] and [main.mk][] then expose as
+  `LDFLAGS.zlib`.
+- `CFLAGS_READLINE` (a.k.a. `CFLAGS.readline`) contains the `CFLAGS`
+  needed for including `libreadline`, `libedit`, or `linenoise`, and
+  `LDFLAGS_READLINE` (a.k.a. `LDFLAGS.readline`) is its link-time
+  counterpart.
+
+It is then up to the Makefile to apply and order the flags however is
+appropriate.
+
+At the end of the configure script, the global `CFLAGS` _ideally_
+holds only flags which are either relevant to all targets or, failing
+that, will have no unintended side-effects on any targets. That said:
+clients frequently pass custom `CFLAGS` to `./configure` or `make` to
+set library-level feature toggles, e.g. `-DSQLITE_OMIT_FOO`, in which
+case there is no practical way to avoid "polluting" the builds of
+arbitrary makefile targets with those. _C'est la vie._
+
+
+[^as-cflags]: But see this article for a detailed discussion of how
+    autosetup currently deals specifically with CFLAGS:
+    <https://msteveb.github.io/autosetup/articles/handling-cflags/>
+
+
+<a name="updating"></a>
+Updating Autosetup
+========================================================================
+
+Updating autosetup is, more often than not, painless. It requires having
+a checked-out copy of [the autosetup git repository][autosetup-git]:
+
+>
+```
+$ git clone https://github.com/msteveb/autosetup
+$ cd autosetup
+# Or, if it's already checked out:
+$ git pull
+```
+
+Then, from the top-most directory of an SQLite checkout:
+
+>
+```
+$ /path/to/autosetup-checkout/autosetup --install .
+$ fossil status # show the modified files
+```
+
+Unless the upgrade made any incompatible changes (which is exceedingly
+rare), that's all there is to it.  After that's done, **apply a patch
+for the change described in the following section**, test the
+configure process, and check it in.
+
+<a name="patching"></a>
+Patching Autosetup for Project-local Changes
+------------------------------------------------------------------------
+
+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 we have a long history of using
+`--enable-debug` for this project's own purposes, we patch autosetup
+to use the name `--autosetup-debug` in place of `--debug`. That
+requires (as of this writing) four small edits in
+[](/file/autosetup/autosetup), as demonstrated in [check-in
+3296c8d3](/info/3296c8d3).
+
+If autosetup is upgraded and this patch is _not_ applied the invoking
+`./configure` will fail loudly because of the declaration of the
+`debug` flag in `auto.def` - duplicated flags are not permitted.

+# Test Procedures For The SQLite TCL Extension
+
+## 1.0 Background
+
+The SQLite TCL extension logic (in the 
+"[tclsqlite.c](/file/src/tclsqlite.c)" source
+file) is statically linked into "textfixture" executable
+which is the program used to do most of the testing
+associated with "make test", "make devtest", and/or
+"make releasetest".  So the functionality of the SQLite
+TCL extension is thoroughly vetted during normal testing.  The
+procedures below are designed to test the loadable extension
+aspect of the SQLite TCL extension, and in particular to verify
+that the "make tclextension-install" build target works and that
+an ordinary tclsh can subsequently run "package require sqlite3".
+
+This procedure can also be used as a template for how to set up
+a local TCL+SQLite development environment.  In other words, it
+can be be used as a guide on how to compile per-user copies of 
+Tcl that are used to develop, test, and debug SQLite.  In that
+case, perhaps make minor changes to the procedure such as:
+
+  *  Make TCLBUILD directory is permanent.
+  *  Enable debugging symbols on the Tcl library build.
+  *  Reduce the optimization level to -O0 for easier debugging.
+  *  Also compile "wish" to go with each "tclsh".

-Activate the user authentication logic by including the
-ext/userauth/userauth.c source code file in the build and
-adding the -DSQLITE_USER_AUTHENTICATION compile-time option.
-The ext/userauth/sqlite3userauth.h header file is available to
-applications to define the interface.
-
-When using the SQLite amalgamation, it is sufficient to append
-the ext/userauth/userauth.c source file onto the end of the
-amalgamation.
-
-The following new APIs are available when user authentication is
-activated:
-
-   int sqlite3_user_authenticate(
-     sqlite3 *db,           /* The database connection */
-     const char *zUsername, /* Username */
-     const char *aPW,       /* Password or credentials */
-     int nPW                /* Number of bytes in aPW[] */
-   );
-   
-   int sqlite3_user_add(
-     sqlite3 *db,           /* Database connection */
-     const char *zUsername, /* Username to be added */
-     const char *aPW,       /* Password or credentials */
-     int nPW,               /* Number of bytes in aPW[] */
-     int isAdmin            /* True to give new user admin privilege */
-   );
-   
-   int sqlite3_user_change(
-     sqlite3 *db,           /* Database connection */
-     const char *zUsername, /* Username to change */
-     const void *aPW,       /* Modified password or credentials */
-     int nPW,               /* Number of bytes in aPW[] */
-     int isAdmin            /* Modified admin privilege for the user */
-   );
-   
-   int sqlite3_user_delete(
-     sqlite3 *db,           /* Database connection */
-     const char *zUsername  /* Username to remove */
-   );
-
-With this extension, a database can be marked as requiring authentication.
-By default a database does not require authentication.
-
-The sqlite3_open(), sqlite3_open16(), and sqlite3_open_v2() interfaces
-work as before: they open a new database connection.  However, if the
-database being opened requires authentication, then attempts to read
-or write from the database will fail with an SQLITE_AUTH error until 
-after sqlite3_user_authenticate() has been called successfully.  The 
-sqlite3_user_authenticate() call will return SQLITE_OK if the 
-authentication credentials are accepted and SQLITE_ERROR if not.
-
-Calling sqlite3_user_authenticate() on a no-authentication-required
-database connection is a harmless no-op.  
-
-If the database is encrypted, then sqlite3_key_v2() must be called first,
-with the correct decryption key, prior to invoking sqlite3_user_authenticate().
-
-To recapitulate: When opening an existing unencrypted authentication-
-required database, the call sequence is:
-
-    sqlite3_open_v2()
-    sqlite3_user_authenticate();
-    /* Database is now usable */
-
-To open an existing, encrypted, authentication-required database, the
-call sequence is:
-
-    sqlite3_open_v2();
-    sqlite3_key_v2();
-    sqlite3_user_authenticate();
-    /* Database is now usable */
-
-When opening a no-authentication-required database, the database
-connection is treated as if it was authenticated as an admin user.
-
-When ATTACH-ing new database files to a connection, each newly attached
-database that is an authentication-required database is checked using
-the same username and password as supplied to the main database.  If that
-check fails, then the ATTACH command fails with an SQLITE_AUTH error.
-
-The sqlite3_user_add() interface can be used (by an admin user only)
-to create a new user.  When called on a no-authentication-required
-database and when A is true, the sqlite3_user_add(D,U,P,N,A) routine
-converts the database into an authentication-required database and
-logs in the database connection D as user U with password P,N.
-To convert a no-authentication-required database into an authentication-
-required database, the isAdmin parameter must be true.  If
-sqlite3_user_add(D,U,P,N,A) is called on a no-authentication-required
-database and A is false, then the call fails with an SQLITE_AUTH error.
-
-Any call to sqlite3_user_add() by a non-admin user results in an error.
-
-Hence, to create a new, unencrypted, authentication-required database,
-the call sequence is:
-
-    sqlite3_open_v2();
-    sqlite3_user_add();
-
-And to create a new, encrypted, authentication-required database, the call
-sequence is:
-
-    sqlite3_open_v2();
-    sqlite3_key_v2();
-    sqlite3_user_add();
-
-The sqlite3_user_delete() interface can be used (by an admin user only)
-to delete a user.  The currently logged-in user cannot be deleted,
-which guarantees that there is always an admin user and hence that
-the database cannot be converted into a no-authentication-required
-database.
-
-The sqlite3_user_change() interface can be used to change a users
-login credentials or admin privilege.  Any user can change their own
-password.  Only an admin user can change another users login
-credentials or admin privilege setting.  No user may change their own 
-admin privilege setting.
-
-The sqlite3_set_authorizer() callback is modified to take a 7th parameter
-which is the username of the currently logged in user, or NULL for a
-no-authentication-required database.
-
-----------------------------------------------------------------------------
-Implementation notes:
-
-An authentication-required database is identified by the presence of a
-new table:
-
-    CREATE TABLE sqlite_user(
-      uname TEXT PRIMARY KEY,
-      isAdmin BOOLEAN,
-      pw BLOB
-    ) WITHOUT ROWID;
-
-The sqlite_user table is inaccessible (unreadable and unwriteable) to
-non-admin users and is read-only for admin users.  However, if the same
-database file is opened by a version of SQLite that omits
-the -DSQLITE_USER_AUTHENTICATION compile-time option, then the sqlite_user
-table will be readable by anybody and writeable by anybody if
-the "PRAGMA writable_schema=ON" statement is run first.
-
-The sqlite_user.pw field is encoded by a built-in SQL function
-"sqlite_crypt(X,Y)".  The two arguments are both BLOBs.  The first argument
-is the plaintext password supplied to the sqlite3_user_authenticate()
-interface.  The second argument is the sqlite_user.pw value and is supplied
-so that the function can extract the "salt" used by the password encoder.
-The result of sqlite_crypt(X,Y) is another blob which is the value that
-ends up being stored in sqlite_user.pw.  To verify credentials X supplied
-by the sqlite3_user_authenticate() routine, SQLite runs:
-
-    sqlite_user.pw == sqlite_crypt(X, sqlite_user.pw)
-
-To compute an appropriate sqlite_user.pw value from a new or modified
-password X, sqlite_crypt(X,NULL) is run.  A new random salt is selected
-when the second argument is NULL.
-
-The built-in version of of sqlite_crypt() uses a simple Ceasar-cypher
-which prevents passwords from being revealed by searching the raw database
-for ASCII text, but is otherwise trivally broken.  For better password
-security, the database should be encrypted using the SQLite Encryption
-Extension or similar technology.  Or, the application can use the
-sqlite3_create_function() interface to provide an alternative
-implementation of sqlite_crypt() that computes a stronger password hash,
-perhaps using a cryptographic hash function like SHA1.

-%description
-SQLite is a software library that implements a self-contained, serverless,
-zero-configuration, transactional SQL database engine.
-Programs that link with the SQLite library can have SQL database access
-without running a separate RDBMS process. The distribution comes with a
-standalone command-line access program (sqlite) that can be used to
-administer an SQLite database and which serves as an example of how to
-use the SQLite library.
