-Installation Instructions
-*************************
-

-Inc.
-
-   Copying and distribution of this file, with or without modification,
-are permitted in any medium without royalty provided the copyright
-notice and this notice are preserved.  This file is offered as-is,
-without warranty of any kind.
-
-Basic Installation
-==================
-
-   Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package.  The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.  Some packages provide this
-`INSTALL' file but do not implement all of the features documented
-below.  The lack of an optional feature in a given package is not
-necessarily a bug.  More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-   The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.
-
-     Running `configure' might take a while.  While running, it prints
-     some messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package, generally using the just-built uninstalled binaries.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.  When installing into a prefix owned by root, it is
-     recommended that the package be configured and built as a regular
-     user, and only the `make install' phase executed with root
-     privileges.
-
-  5. Optionally, type `make installcheck' to repeat any self-tests, but
-     this time using the binaries in their final installed location.
-     This target does not install anything.  Running this target as a
-     regular user, particularly if the prior `make install' required
-     root privileges, verifies that the installation completed
-     correctly.
-
-  6. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-  7. Often, you can also type `make uninstall' to remove the installed
-     files again.  In practice, not all packages have tested that
-     uninstallation works correctly, even though it is required by the
-     GNU Coding Standards.
-
-  8. Some packages, particularly those that use Automake, provide `make
-     distcheck', which can by used by developers to test that all other
-     targets like `make install' and `make uninstall' work correctly.
-     This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.  This
-is known as a "VPATH" build.
-
-   With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
-   By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc.  You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.  In general, the
-default for these options is expressed in terms of `${prefix}', so that
-specifying just `--prefix' will affect all of the other directory
-specifications that were not explicitly provided.
-
-   The most portable way to affect installation locations is to pass the
-correct locations to `configure'; however, many packages provide one or
-both of the following shortcuts of passing variable assignments to the
-`make install' command line to change installation locations without
-having to reconfigure or recompile.
-
-   The first method involves providing an override variable for each
-affected directory.  For example, `make install
-prefix=/alternate/directory' will choose an alternate location for all
-directory configuration variables that were expressed in terms of
-`${prefix}'.  Any directories that were specified during `configure',
-but not in terms of `${prefix}', must each be overridden at install
-time for the entire installation to be relocated.  The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.
-However, some platforms have known limitations with the semantics of
-shared libraries that end up requiring recompilation when using this
-method, particularly noticeable in packages that use GNU Libtool.
-
-   The second method involves providing the `DESTDIR' variable.  For
-example, `make install DESTDIR=/alternate/directory' will prepend
-`/alternate/directory' before all installation names.  The approach of
-`DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters.  On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of `${prefix}'
-at `configure' time.
-
-Optional Features
-=================
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-   Some packages offer the ability to configure how verbose the
-execution of `make' will be.  For these packages, running `./configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with `make V=1'; while running `./configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with `make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   HP-UX `make' updates targets which have the same time stamps as
-their prerequisites, which makes it generally unusable when shipped
-generated files such as `configure' are involved.  Use GNU `make'
-instead.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
-a workaround.  If GNU CC is not installed, it is therefore recommended
-to try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
-   On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug.  Until the bug is fixed you can use this workaround:
-
-     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
-     Print a summary of the options unique to this package's
-     `configure', and exit.  The `short' variant lists options used
-     only in the top level, while the `recursive' variant lists options
-     also present in any nested packages.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--prefix=DIR'
-     Use DIR as the installation prefix.  *note Installation Names::
-     for more details, including other options available for fine-tuning
-     the installation locations.
-
-`--no-create'
-`-n'
-     Run the configure checks, but stop before creating any output
-     files.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-SUMMARY OF HOW TO BUILD
-=======================
+WHY USE THIS PACKAGE?
+=====================
+
+The canonical make system for SQLite requires TCL as part of the build
+process.  Various TCL scripts are used to generate parts of the code and
+TCL is used to run tests.  But some people would prefer to build SQLite
+using only generic tools and without having to install TCL.  The purpose
+of this package is to provide that capability.
+
+This package contains a pre-build SQLite amalgamation file "sqlite3.c"
+(and its associated header file "sqlite3.h").  Because the
+amalgamation has been pre-built, no TCL is required for the code
+generate (the configure script itself is written in TCL but it can use
+the embedded copy of JimTCL).
+
+REASONS TO USE THE CANONICAL BUILD SYSTEM RATHER THAN THIS PACKAGE
+==================================================================
+
+ * the canonical build system allows you to run tests to verify that
+   the build worked
+ * the canonical build system supports more compile-time options
+ * the canonical build system works for any arbitrary check-in to
+   the SQLite source tree

-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

+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 configuration-related TCL code is spread across the
+following files:
+
+- [proj.tcl][]: project-agnostic utility code for autosetup-driven
+  projects. This file is designed to be shared between this project,
+  other projects managed under the SQLite/Hwaci umbrella
+  (e.g. Fossil), and personal projects of SQLite's developers.  It is
+  essentially an amalgamation of a decade's worth of autosetup-related
+  utility code.
+- [sqlite-config.tcl][]: utility code which is too project-specific
+  for `proj.tcl`. We split this out of `auto.def` so that it can be
+  used by both `auto.def` and...
+- [auto.def][]: the primary driver for the `./configure` process.
+  When we talk about "the configure script," we're technically
+  referring to this file, though it actually contains very little
+  of the TCL code.
+- [autoconf/auto.def][]: the main driver script for the "autoconf"
+  bundle's configure script. It is essentially a slightly trimmed-down
+  version of the main `auto.def` file. The `autoconf` dir was ported
+  from the Autotools to Autosetup in the 3.49.0 dev cycle but retains
+  the "autoconf" name to minimize downstream disruption.
+
+
+<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
+from a casual perusal of the relevant TCL files. The complete docs of
+those with `proj-` prefix can be found in [proj.tcl][] and those with
+an `sqlite-` prefix are in [sqlite-config.tcl][]. The others are part
+of Autosetup's core packages and 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`.\  
+    Tip: adding `-O0` to `.env-CFLAGS` reduces rebuild times
+    considerably at the cost of performance in `make devtest` and the
+    like.
+
+- **`proj-fatal msg`**\  
+  Emits `$msg` to stderr and exits with non-zero. Its differences from
+  autosetup's `user-error` are purely cosmetic.
+
+- **`proj-if-opt-truthy flag thenScript ?elseScript?`**\  
+  Evals `thenScript` if the given `--flag` is truthy, else it
+  evals the optional `elseScript`.
+
+- **`proj-indented-notice ?-error? ?-notice? msg`**\  
+  Breaks its `msg` argument into lines, trims them, and emits them
+  with consistent indentation. Exactly how it emits depends on the
+  flags passed to it (or not), as covered in its docs. This will stick
+  out starkly from normal output and is intended to be used only for
+  important notices.
+
+- **`proj-opt-truthy flag`**\  
+  Returns 1 if `--flag`'s value is "truthy," i.e. one of (1, on,
+  enabled, yes, true).
+
+- **`proj-opt-was-provided FLAG`**\  
+  Returns 1 if `--FLAG` was explicitly provided to configure,
+  else 0. This distinction can be used to determine, e.g., whether
+  `--with-readline` was provided or whether we're searching for
+  readline by default. In the former case, failure to find it should
+  be treated as fatal, where in the latter case it's not.\  
+  Unlike most functions which deal with `--flags`, this one does not
+  validate that `$FLAG` is a registered flag so will not fail fatally
+  if `$FLAG` is not registered as an Autosetup option.
+
+- **`proj-val-truthy value`**\  
+  Returns 1 if `$value` is "truthy," See `proj-opt-truthy` for the definition
+  of "truthy."
+
+- **`proj-warn msg`**\  
+  Emits `$msg` to stderr. Closely-related is autosetup's `user-notice`
+  (described below).
+
+- **`sqlite-add-feature-flag ?-shell? FLAG...`**\  
+  Adds the given feature flag to the CFLAGS which are specific to
+  building libsqlite3. It's intended to be passed one or more
+  `-DSQLITE_ENABLE_...`, or similar, flags. If the `-shell` flag is
+  used then it also passes its arguments to
+  `sqlite-add-shell-opt`. This is a no-op if `FLAG` is not provided or
+  is empty.
+
+- **`sqlite-add-shell-opt FLAG...`**\  
+  The shell-specific counterpart of `sqlite-add-feature-flag` which
+  only adds the given flag(s) to the CLI-shell-specific CFLAGS.
+
+- **`sqlite-configure BUILD-NAME {script}`**\  
+  This is where all configure `--flags` are defined for all known
+  build modes ("canonical" or "autoconf"). After processing all flags,
+  this function runs `$script`, which contains the build-mode-specific
+  configuration bits, and then runs any finalization bits which are
+  common to all build modes. The `auto.def` files are intended to contain
+  exactly two commands:
+  `use sqlite-config; sqlite-configure BUILD-NAME {script}`
+
+- **`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
+========================================================================
+
+One of the significant benefits of using Autosetup is that (A) this
+project uses many TCL scripts in the build process and (B) Autosetup
+comes with a TCL interpreter named [JimTCL][].
+
+It is important that any TCL files used by the configure process and
+makefiles 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. Contrariwise, code-generation
+scripts invoked via `make` may use `[file normalize]`, as they'll use
+`./jimsh` or `tclsh` instead of `./jimsh0`.
+
+
+Known TCL Incompatibilities
+------------------------------------------------------------------------
+
+A summary of known incompatibilities in JimTCL
+
+- **CRNL line endings**: prior to 2025-02-05 `fconfigure -translation ...`
+  was a no-op in JimTCL, and it emits CRNL line endings by default on
+  Windows.  Since then, it supports `-translation binary`, which is
+  close enough to `-translation lf` for our purposes. When working
+  with files using the `open` command, it is important to use mode
+  `"rb"` or `"wb"`, as appropriate, so that the output does not get
+  CRNL-mangled on Windows.
+
+- **`file copy`** does not support multiple source files. See
+  [](/info/61f18c96183867fe) for a workaround.
+
+- **Regular expressions**:
+
+  - Patterns treat `\nnn` octal values as back-references (which it
+    does not support). Those can be reformulated as demonstrated in
+    [](/info/aeac23359bb681c0).
+
+  - `regsub` does not support the `\y` flag. A workaround is demonstrated
+    in [](/info/c2e5dd791cce3ec4).

+<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 from `@X_Y@`
+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 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 this project has a long history of
+using `--enable-debug`, 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.
+
+<a name="branch-customization"></a>
+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: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.

+#
+
+#
+# Routines for Steve Bennett's autosetup which are common to trees
+# managed in and around the umbrella of the SQLite project.
+#
+# The intent is that these routines be relatively generic, independent
+# of a given project.
+#
+# For practical purposes, the copy of this file hosted in the SQLite
+# project is the "canonical" one:
+#
+# https://sqlite.org/src/file/autosetup/proj.tcl
+#
+# This file was initially derived from one used in the libfossil
+# project, authored by the same person who ported it here, and this is
+# noted here only as an indication that there are no licensing issues
+# despite this code having a handful of near-twins running around a
+# handful of third-party source trees.
+#
+# Design notes:
+#
+# - Symbols with _ separators are intended for internal use within
+#   this file, and are not part of the API which auto.def files should
+#   rely on. Symbols with - separators are public APIs.
+#
+# - By and large, autosetup prefers to update global state with the
+#   results of feature checks, e.g. whether the compiler supports flag
+#   --X.  In this developer's opinion that (A) causes more confusion
+#   than it solves[^1] and (B) adds an unnecessary layer of "voodoo"
+#   between the autosetup user and its internals. This module, in
+#   contrast, instead injects the results of its own tests into
+#   well-defined variables and leaves the integration of those values
+#   to the caller's discretion.
+#
+# [1]: As an example: testing for the -rpath flag, using
+# cc-check-flags, can break later checks which use
+# [cc-check-function-in-lib ...] because the resulting -rpath flag
+# implicitly becomes part of those tests. In the case of an rpath
+# test, downstream tests may not like the $prefix/lib path added by
+# the rpath test. To avoid such problems, we avoid (intentionally)
+# updating global state via feature tests.
+#
+

+# internal stuff we need stored.

+#
+#   -flag => defaultValue
+#   -----^--^ (with spaces there!)
+#
+# Repeated for each flag.
+#
+# The first form represents a basic flag with no associated
+# following argument. The second form extracts its value
+# from the following argument in $argvName.
+#
+# The first argument to this function is the name of a var holding the
+# args to parse. It will be overwritten, possibly with a smaller list.
+#
+# The second argument the name of an array variable to create in the
+# caller's scope. (Pneumonic: => points to the next argument.)
+#
+# For the first form of flag, $script is run in the caller's scope if
+# $argv contains -flag, and the result of that script is the new value
+# for $tgtArrayName(-flag). This function intercepts [return $val]
+# from $script. Any empty script will result in the flag having ""
+# assigned to it.
+#
+# The args list is only inspected until the first argument which is
+# not described by $prototype. i.e. the first "non-flag" (not counting
+# values consumed for flags defined like --flag=>default).
+#
+# If a "--" flag is encountered, no more arguments are inspected as
+# flags. If "--" is the first non-flag argument, the "--" flag is
+# removed from the results but all remaining arguments are passed
+# through. If "--" appears after the first non-flag, it is retained.
+#
+# This function assumes that each flag is unique, and using a flag
+# more than once behaves in a last-one-wins fashion.
+#
+# Any argvName entries not described in $prototype are not treated as
+# flags.
+#
+# Returns the number of flags it processed in $argvName.
+#
+# Example:
+#
+# set args [list -foo -bar {blah} 8 9 10 -theEnd]

+#   -foo    0  {expr 1}
+#   -bar    => 0
+#   -no-baz 2  {return 0}
+# }
+#
+# After that $flags would contain {-foo 1 -bar {blah} -no-baz 2}
+# and $args would be {8 9 10 -theEnd}.
+#
+# Potential TODOs: consider using lappend instead of set so that any
+# given flag can be used more than once. Or add a syntax to indicate
+# that multiples are allowed. Also consider searching the whole
+# argv list, rather than stopping at the first non-flag

+  # A gentle introduction to flags handling in autosetup
+  #
+  # Reference: https://msteveb.github.io/autosetup/developer/
+  #
+  # All configure flags must be described in an 'options' call. The
+  # general syntax is:
+  #
+  #  FLAG => {Help text}
+  #
+  # Where FLAG can have any of the following formats:
+  #
+  #   boolopt            => "a boolean option which defaults to disabled"
+  #   boolopt2=1         => "a boolean option which defaults to enabled"
+  #   stringopt:         => "an option which takes an argument, e.g. --stringopt=value"
+  #   stringopt:DESCR    => As for stringopt: with a description for the value
+  #   stringopt2:=value  => "an option where the argument is optional and defaults to 'value'"
+  #   optalias booltopt3 => "a boolean with a hidden alias. --optalias is not shown in --help"
+  #
+  # Autosetup does no small amount of specialized handling for flags,
+  # especially booleans. Each bool-type --FLAG implicitly gets
+  # --enable-FLAG and --disable-FLAG forms. That can lead lead to some
+  # confusion when writing help text. For example:
+  #
+  #   options { json=1 {Disable JSON functions} }
+  #
+  # The reason the help text says "disable" is because a boolean option
+  # which defaults to true is, in the --help text, rendered as:
+  #
+  #   --disable-json          Disable JSON functions
+  #
+  # Whereas a bool flag which defaults to false will instead render as:
+  #
+  #   --enable-FLAG
+  #
+  # Non-boolean flags, in contrast, use the names specifically given to
+  # them in the [options] invocation. e.g. "with-tcl" is the --with-tcl
+  # flag.
+  #
+  # Fetching values for flags:
+  #
+  #   booleans: use one of:
+  #     - [opt-bool FLAG] is autosetup's built-in command for this, but we
+  #       have some convenience variants:
+  #     - [proj-opt-truthy FLAG]
+  #     - [proj-opt-if-truthy FLAG {THEN} {ELSE}]
+  #
+  #   Non-boolean (i.e. string) flags:
+  #     - [opt-val FLAG ?default?]
+  #     - [opt-str ...] - see the docs in ./autosetup/autosetup
+  #
+  # [proj-opt-was-provided] can be used to determine whether a flag was
+  # explicitly provided, which is often useful for distinguishing from
+  # the case of a default value.

+# "ok"] [msg-result "no"] unless -nostatus is used, in which case the
+# caller is responsible for emitting at least a newline when it's
+# done. The -msg-0 and -msg-1 flags can be used to change the ok/no

+#
+# This function checks for a cache hit before running $script and
+# caching the result. If no hit is found then $script is run in the

+#
+#   -quiet = disable output from Autosetup's msg-checking and
+#    msg-result for the duration of the $script check. Note that when
+#    -quiet is in effect, Autosetup's user-notice can be used to queue
+#    up output to appear after the check is done. Also note that

+#
+#    -name.pkg pkg-provide-name: The extension's name for purposes of
+#     Tcl_PkgProvide(), [package require], and friends. It defaults to
+#     the `-name`, and is normally the same, but some projects (like
+#     SQLite) have a different name here than they do in their
+#     historical TEA PACKAGE_NAME.
+#
+#    -version version: The extension's package version. Defaults to
+#     0.0.0.
+#
+#    -libDir dirName: The base name of the directory into which this
+#     extension should be installed. It defaults to a concatenation of
+#     `-name.pkg` and `-version`.
+#
+#    -loadPrefix prefix: For use as the second argument passed to
+#     Tcl's `load` command in the package-loading process. It defaults
+#     to title-cased `-name.pkg` because Tcl's `load` plugin system
+#     expects it in that form.
+#
+#    -options {...}: If provided, it must be a list compatible with
+#     Autosetup's `options-add` function. These can also be set up via

+#
+#    -vsatisfies {{...} ...}: Expects a list-of-lists of conditions
+#     for Tcl's `package vsatisfies` command: each list entry is a
+#     sub-list of `{PkgName Condition...}`.  Teaish inserts those
+#     checks via its default pkgIndex.tcl.in and _teaish.tester.tcl.in
+#     templates to verify that the system's package dependencies meet

+#     teaish will run on, but some extensions may require newer
+#     versions or dependencies on other packages. As a special case,
+#     if `-vsatisfies` is given a single token, e.g. `8.6-`, then it
+#     is transformed into `{Tcl $thatToken}`, i.e. it checks the Tcl

+#    -pragmas {...}  A list of infrequently-needed lower-level
+#     directives which can influence teaish, including:
+#
+#      static-pkgIndex.tcl: tells teaish that the client manages their
+#      own pkgIndex.tcl, so that teaish won't try to overwrite it
+#      using a template.
+#
+#      no-dist: tells teaish to elide the "make dist" recipe from the
+#      makefile so that the client can implement it.
+#
+#      no-dll: tells teaish to elide the makefile rules which build
+#      the DLL, as well as any templated test script and pkgIndex.tcl
+#      references to them. The intent here is to (A) support
+#      client-defined build rules for the DLL and (B) eventually
+#      support script-only extensions.
+#
+# Unsupported flags or pragmas will trigger an error.
+#
+# Potential pothole: setting certain state, e.g. -version, after the
+# initial call requires recalculating of some [define]s. Any such
+# changes should be made as early as possible in teaish-configure so
+# that any later use of those [define]s gets recorded properly (not
+# with the old value).  This is particularly relevant when it is not
+# possible to determine the -version or -name until teaish-configure
+# has been called, and it's updated dynamically from
+# teaish-configure. Notably:
+#
+#   - If -version or -name are updated, -libDir will almost certainly
+#     need to be explicitly set along with them.
+#
+#   - If -name is updated, -loadPrefix probably needs to be as well.

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX

-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.

-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>

-  LT_SYS_LIBRARY_PATH
-              User-defined run-time library search path.
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

-## dummy dependencies for each header file.  Too bad gcc doesn't do
-## this for us directly.
-## Some versions of gcc put a space before the ':'.  On the theory

-## ------ ##
-## Usage. ##
-## ------ ##
-
-# This file is a library for parsing options in your shell scripts along
-# with assorted other useful supporting features that you can make use
-# of too.
-#
-# For the simplest scripts you might need only:
-#
-#   #!/bin/sh
-#   . relative/path/to/funclib.sh
-#   . relative/path/to/options-parser
-#   scriptversion=1.0
-#   func_options ${1+"$@"}
-#   eval set dummy "$func_options_result"; shift
-#   ...rest of your script...
-#
-# In order for the '--version' option to work, you will need to have a
-# suitably formatted comment like the one at the top of this file
-# starting with '# Written by ' and ending with '# warranty; '.
-#
-# For '-h' and '--help' to work, you will also need a one line
-# description of your script's purpose in a comment directly above the
-# '# Written by ' line, like the one at the top of this file.
-#
-# The default options also support '--debug', which will turn on shell
-# execution tracing (see the comment above debug_cmd below for another
-# use), and '--verbose' and the func_verbose function to allow your script
-# to display verbose messages only when your user has specified
-# '--verbose'.
-#
-# After sourcing this file, you can plug processing for additional
-# options by amending the variables from the 'Configuration' section
-# below, and following the instructions in the 'Option parsing'
-# section further down.
-
-## -------------- ##
-## Configuration. ##
-## -------------- ##
-
-# You should override these variables in your script after sourcing this
-# file so that they reflect the customisations you have added to the
-# option parser.
-
-# The usage line for option parsing errors and the start of '-h' and
-# '--help' output messages. You can embed shell variables for delayed
-# expansion at the time the message is displayed, but you will need to
-# quote other shell meta-characters carefully to prevent them being
-# expanded when the contents are evaled.
-usage='$progpath [OPTION]...'
-
-# Short help message in response to '-h' and '--help'.  Add to this or
-# override it after sourcing this library to reflect the full set of
-# options your script accepts.
-usage_message="\

+******************************************************************************
+**
+** This file contains code to implement the percentile(Y,P) SQL function
+** and similar as described below:
+**
+**   (1)  The percentile(Y,P) function is an aggregate function taking
+**        exactly two arguments.
+**
+**   (2)  If the P argument to percentile(Y,P) is not the same for every
+**        row in the aggregate then an error is thrown.  The word "same"
+**        in the previous sentence means that the value differ by less
+**        than 0.001.
+**
+**   (3)  If the P argument to percentile(Y,P) evaluates to anything other
+**        than a number in the range of 0.0 to 100.0 inclusive then an
+**        error is thrown.
+**
+**   (4)  If any Y argument to percentile(Y,P) evaluates to a value that
+**        is not NULL and is not numeric then an error is thrown.
+**
+**   (5)  If any Y argument to percentile(Y,P) evaluates to plus or minus
+**        infinity then an error is thrown.  (SQLite always interprets NaN
+**        values as NULL.)
+**
+**   (6)  Both Y and P in percentile(Y,P) can be arbitrary expressions,
+**        including CASE WHEN expressions.
+**
+**   (7)  The percentile(Y,P) aggregate is able to handle inputs of at least
+**        one million (1,000,000) rows.
+**
+**   (8)  If there are no non-NULL values for Y, then percentile(Y,P)
+**        returns NULL.
+**
+**   (9)  If there is exactly one non-NULL value for Y, the percentile(Y,P)
+**        returns the one Y value.
+**
+**  (10)  If there N non-NULL values of Y where N is two or more and
+**        the Y values are ordered from least to greatest and a graph is
+**        drawn from 0 to N-1 such that the height of the graph at J is
+**        the J-th Y value and such that straight lines are drawn between
+**        adjacent Y values, then the percentile(Y,P) function returns
+**        the height of the graph at P*(N-1)/100.
+**
+**  (11)  The percentile(Y,P) function always returns either a floating
+**        point number or NULL.
+**
+**  (12)  The percentile(Y,P) is implemented as a single C99 source-code
+**        file that compiles into a shared-library or DLL that can be loaded
+**        into SQLite using the sqlite3_load_extension() interface.
+**
+**  (13)  A separate median(Y) function is the equivalent percentile(Y,50).
+**
+**  (14)  A separate percentile_cont(Y,P) function is equivalent to
+**        percentile(Y,P/100.0).  In other words, the fraction value in
+**        the second argument is in the range of 0 to 1 instead of 0 to 100.
+**
+**  (15)  A separate percentile_disc(Y,P) function is like
+**        percentile_cont(Y,P) except that instead of returning the weighted
+**        average of the nearest two input values, it returns the next lower
+**        value.  So the percentile_disc(Y,P) will always return a value
+**        that was one of the inputs.
+**
+**  (16)  All of median(), percentile(Y,P), percentile_cont(Y,P) and
+**        percentile_disc(Y,P) can be used as window functions.
+**
+** Differences from standard SQL:
+**
+**  *  The percentile_cont(X,P) function is equivalent to the following in
+**     standard SQL:
+**
+**         (percentile_cont(P) WITHIN GROUP (ORDER BY X))
+**
+**     The SQLite syntax is much more compact.  The standard SQL syntax
+**     is also supported if SQLite is compiled with the
+**     -DSQLITE_ENABLE_ORDERED_SET_AGGREGATES option.
+**
+**  *  No median(X) function exists in the SQL standard.  App developers
+**     are expected to write "percentile_cont(0.5)WITHIN GROUP(ORDER BY X)".
+**
+**  *  No percentile(Y,P) function exists in the SQL standard.  Instead of
+**     percential(Y,P), developers must write this:
+**     "percentile_cont(P/100.0) WITHIN GROUP (ORDER BY Y)".  Note that
+**     the fraction parameter to percentile() goes from 0 to 100 whereas
+**     the fraction parameter in SQL standard percentile_cont() goes from
+**     0 to 1.
+**
+** Implementation notes as of 2024-08-31:
+**
+**  *  The regular aggregate-function versions of these routines work
+**     by accumulating all values in an array of doubles, then sorting
+**     that array using quicksort before computing the answer. Thus
+**     the runtime is O(NlogN) where N is the number of rows of input.
+**
+**  *  For the window-function versions of these routines, the array of
+**     inputs is sorted as soon as the first value is computed.  Thereafter,
+**     the array is kept in sorted order using an insert-sort.  This
+**     results in O(N*K) performance where K is the size of the window.
+**     One can imagine alternative implementations that give O(N*logN*logK)
+**     performance, but they require more complex logic and data structures.
+**     The developers have elected to keep the asymptotically slower
+**     algorithm for now, for simplicity, under the theory that window
+**     functions are seldom used and when they are, the window size K is
+**     often small.  The developers might revisit that decision later,
+**     should the need arise.

+**     const char *zOldVfsName,        // Name of the underlying VFS
+**     int (*xOut)(const char*,void*), // Output routine.  ex: fputs
+**     void *pOutArg,                  // 2nd argument to xOut.  ex: stderr
+**     int makeDefault                 // Make the new VFS the default
+**   );
+**
+** Applications that want to trace their VFS usage must provide a callback
+** function with this prototype:
+**
+**   int traceOutput(const char *zMessage, void *pAppData);
+**
+** This function will "output" the trace messages, where "output" can
+** mean different things to different applications.  The traceOutput function
+** for the command-line shell (see shell.c) is "fputs" from the standard
+** library, which means that all trace output is written on the stream
+** specified by the second argument.  In the case of the command-line shell
+** the second argument is stderr.  Other applications might choose to output
+** trace information to a file, over a socket, or write it into a buffer.
+**
+** The vfstrace_register() function creates a new "shim" VFS named by
+** the zTraceName parameter.  A "shim" VFS is an SQLite backend that does
+** not really perform the duties of a true backend, but simply filters or
+** interprets VFS calls before passing them off to another VFS which does
+** the actual work.  In this case the other VFS - the one that does the
+** real work - is identified by the second parameter, zOldVfsName.  If
+** the 2nd parameter is NULL then the default VFS is used.  The common
+** case is for the 2nd parameter to be NULL.
+**
+** The third and fourth parameters are the pointer to the output function
+** and the second argument to the output function.  For the SQLite
+** command-line shell, when the -vfstrace option is used, these parameters
+** are fputs and stderr, respectively.
+**
+** The fifth argument is true (non-zero) to cause the newly created VFS
+** to become the default VFS.  The common case is for the fifth parameter
+** to be true.
+**
+** The call to vfstrace_register() simply creates the shim VFS that does
+** tracing.  The application must also arrange to use the new VFS for
+** all database connections that are created and for which tracing is 
+** desired.  This can be done by specifying the trace VFS using URI filename
+** notation, or by specifying the trace VFS as the 4th parameter to
+** sqlite3_open_v2() or by making the trace VFS be the default (by setting
+** the 5th parameter of vfstrace_register() to 1).
+**
+**
+** ENABLING VFSTRACE IN A COMMAND-LINE SHELL
+**
+** The SQLite command line shell implemented by the shell.c source file
+** can be used with this module.  To compile in -vfstrace support, first
+** gather this file (test_vfstrace.c), the shell source file (shell.c),
+** and the SQLite amalgamation source files (sqlite3.c, sqlite3.h) into
+** the working directory.  Then compile using a command like the following:
+**
+**    gcc -o sqlite3 -Os -I. -DSQLITE_ENABLE_VFSTRACE \
+**        -DSQLITE_THREADSAFE=0 -DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_RTREE \
+**        -DHAVE_READLINE -DHAVE_USLEEP=1 \
+**        shell.c test_vfstrace.c sqlite3.c -ldl -lreadline -lncurses
+**
+** The gcc command above works on Linux and provides (in addition to the
+** -vfstrace option) support for FTS3 and FTS4, RTREE, and command-line
+** editing using the readline library.  The command-line shell does not
+** use threads so we added -DSQLITE_THREADSAFE=0 just to make the code
+** run a little faster.   For compiling on a Mac, you'll probably need
+** to omit the -DHAVE_READLINE, the -lreadline, and the -lncurses options.
+** The compilation could be simplified to just this:
+**
+**    gcc -DSQLITE_ENABLE_VFSTRACE \
+**         shell.c test_vfstrace.c sqlite3.c -ldl -lpthread
+**
+** In this second example, all unnecessary options have been removed
+** Note that since the code is now threadsafe, we had to add the -lpthread
+** option to pull in the pthreads library.
+**
+** To cross-compile for windows using MinGW, a command like this might
+** work:
+**
+**    /opt/mingw/bin/i386-mingw32msvc-gcc -o sqlite3.exe -Os -I \
+**         -DSQLITE_THREADSAFE=0 -DSQLITE_ENABLE_VFSTRACE \
+**         shell.c test_vfstrace.c sqlite3.c
+**
+** Similar compiler commands will work on different systems.  The key
+** invariants are (1) you must have -DSQLITE_ENABLE_VFSTRACE so that
+** the shell.c source file will know to include the -vfstrace command-line
+** option and (2) you must compile and link the three source files
+** shell,c, test_vfstrace.c, and sqlite3.c.
+**
+** RUNTIME CONTROL OF VFSTRACE OUTPUT
+**
+** The application can use the "vfstrace" pragma to control which VFS
+** APIs are traced.  To disable all output:
+**
+**    PRAGMA vfstrace('-all');
+**
+** To enable all output (which is the default setting):
+**
+**    PRAGMA vfstrace('+all');
+**
+** Individual APIs can be enabled or disabled by name, with or without
+** the initial "x" character.  For example, to set up for tracing lock
+** primitives only:
+**
+**    PRAGMA vfstrace('-all, +Lock,Unlock,ShmLock');
+**
+** The argument to the vfstrace pragma ignores capitalization and any
+** characters other than alphabetics, '+', and '-'.

+/* Implementation of the order-by-subquery optimization:
+**
+** WhereLoop pLoop, which the iLoop-th term of the nested loop, is really
+** a subquery or CTE that has an ORDER BY clause.  See if any of the terms
+** in the subquery ORDER BY clause will satisfy pOrderBy from the outer
+** query.  Mark off all satisfied terms (by setting bits in *pOBSat) and
+** return TRUE if they do.  If not, return false.
+**
+** Example:
+**
+**    CREATE TABLE t1(a,b,c, PRIMARY KEY(a,b));
+**    CREATE TABLE t2(x,y);
+**    WITH t3(p,q) AS MATERIALIZED (SELECT x+y, x-y FROM t2 ORDER BY x+y)
+**       SELECT * FROM t3 JOIN t1 ON a=q ORDER BY p, b;
+**
+** The CTE named "t3" comes out in the natural order of "p", so the first
+** first them of "ORDER BY p,b" is satisfied by a sequential scan of "t3"
+** and sorting only needs to occur on the second term "b".
+**
+** Limitations:
+**
+** (1)  The optimization is not applied if the outer ORDER BY contains
+**      a COLLATE clause.  The optimization might be applied if the
+**      outer ORDER BY uses NULLS FIRST, NULLS LAST, ASC, and/or DESC as
+**      long as the subquery ORDER BY does the same.  But if the
+**      outer ORDER BY uses COLLATE, even a redundant COLLATE, the
+**      optimization is bypassed.
+**
+** (2)  The subquery ORDER BY terms must exactly match subquery result
+**      columns, including any COLLATE annotations.  This routine relies
+**      on iOrderByCol to do matching between order by terms and result
+**      columns, and iOrderByCol will not be set if the result column
+**      and ORDER BY collations differ.
+**
+** (3)  The subquery and outer ORDER BY can be in opposite directions as
+**      long as  the subquery is materialized.  If the subquery is
+**      implemented as a co-routine, the sort orders must be in the same
+**      direction because there is no way to run a co-routine backwards.

+** Compute the maximum number of paths in the solver algorithm, for
+** queries that have three or more terms in the FROM clause.  Queries with
+** two or fewer FROM clause terms are handled by the caller.
+**
+** Query planning is NP-hard.  We must limit the number of paths at
+** each step of the solver search algorithm to avoid exponential behavior.
+**
+** The value returned is a tuning parameter.  Currently the value is:
+**
+**     18    for star queries
+**     12    otherwise
+**
+** For the purposes of this heuristic, a star-query is defined as a query
+** with a large central table that is joined using an INNER JOIN,
+** not CROSS or OUTER JOINs, against four or more smaller tables.
+** The central table is called the "fact" table.  The smaller tables
+** that get joined are "dimension tables".  Also, any table that is
+** self-joined cannot be a dimension table; we assume that dimension
+** tables may only be joined against fact tables.
+**
+** SIDE EFFECT:  (and really the whole point of this subroutine)
+**
+** If pWInfo describes a star-query, then the cost for SCANs of dimension
+** WhereLoops is increased to be slightly larger than the cost of a SCAN
+** in the fact table.  Only SCAN costs are increased.  SEARCH costs are
+** unchanged. This heuristic helps keep fact tables in outer loops. Without
+** this heuristic, paths with fact tables in outer loops tend to get pruned
+** by the mxChoice limit on the number of paths, resulting in poor query
+** plans.  See the starschema1.test test module for examples of queries
+** that need this heuristic to find good query plans.
+**
+** This heuristic can be completely disabled, so that no query is
+** considered a star-query, using SQLITE_TESTCTRL_OPTIMIZATION to
+** disable the SQLITE_StarQuery optimization.  In the CLI, the command
+** to do that is:  ".testctrl opt -starquery".
+**
+** HISTORICAL NOTES:
+**
+** This optimization was first added on 2024-05-09 by check-in 38db9b5c83d.
+** The original optimization reduced the cost and output size estimate for
+** fact tables to help them move to outer loops.  But months later (as people
+** started upgrading) performance regression reports started caming in,
+** including:

+**    forum post b18ef983e68d06d1 (2024-12-21)

+**    forum post d87570a145599033 (2025-01-17)
+**
+** To address these, the criteria for a star-query was tightened to exclude
+** cases where the fact and dimensions are separated by an outer join, and
+** the affect of star-schema detection was changed to increase the rRun cost
+** on just full table scans of dimension tables, rather than reducing costs

-	$ ./configure --prefix=/opt/tcl
-	$ make
-	$ make install

-to create a Makefile. See the tcl/win/README file for the URL of

+This is the SQLite extension for Tcl using something akin to
+the Tcl Extension Architecture (TEA). To build it:
+
+    ./configure ...flags...
+
+e.g.:
+
+    ./configure --with-tcl=/path/to/tcl/install/root
+
+or:
+
+    ./configure --with-tclsh=/path/to/tcl/install/root
+
+Run ./configure --help for the full list of flags.
+
+The configuration process will fail if tclConfig.sh cannot be found.
+
+The makefile will only honor CFLAGS and CPPFLAGS passed to the
+configure script, not those directly passed to the makefile.
+
+Then:
+
+    make test install
+
+----------------------- THE PREFERRED WAY ---------------------------
+
+The preferred way to build the TCL extension for SQLite is to use the
+canonical source code tarball.  For Unix:
+
+    ./configure --with-tclsh=$(TCLSH)
+    make tclextension-install
+
+For Windows:
+
+    nmake /f Makefile.msc tclextension-install TCLSH_CMD=$(TCLSH)
+
+In both of the above, replace $(TCLSH) with the full pathname of
+of the tclsh that you want the SQLite extension to work with.  See
+step-by-step instructions at the links below for more information:
+
+    https://sqlite.org/src/doc/trunk/doc/compile-for-unix.md
+    https://sqlite.org/src/doc/trunk/doc/compile-for-windows.md
+
+And info about the extension's Tcl interface can be found at:
+
+    https://sqlite.org/tclsqlite.html
+
+The whole point of the amalgamation-autoconf tarball (in which this
+README.txt file is embedded) is to provide a means of compiling SQLite
+that does not require first installing TCL and/or "tclsh".  The
+canonical Makefile in the SQLite source tree provides more
+capabilities (such as the the ability to run test cases to ensure that
+the build worked) and is better maintained.  The only downside of the
+canonical Makefile is that it requires a TCL installation.  But if you
+are wanting to build the TCL extension for SQLite, then presumably you
+already have a TCL installation.  So why not just use the more-capable
+and better-maintained canoncal Makefile?
+
+As of version 3.50.0, this build process uses "teaish":
+
+    https://fossil.wanderinghorse.net/r/teaish
+
+which is conceptually derived from the pre-3.50 toolchain, TEA:
+
+    http://core.tcl-lang.org/tclconfig
+    http://core.tcl-lang.org/sampleextension
+
+It to works for us.  It might also work for you.  But we cannot
+promise that.
+
+If you want to use this TEA builder and it works for you, that's fine.
+But if you have trouble, the first thing you should do is go back
+to using the canonical Makefile in the SQLite source tree.

-\`configure' configures sqlite 3.46.1 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:

-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

-# Microsoft Visual C++ makefile for use with nmake.exe v1.62+ (VC++ 5.0+)
-#
-# This makefile is based upon the Tcl 8.4 Makefile.vc and modified to 
-# make it suitable as a general package makefile. Look for the word EDIT
-# which marks sections that may need modification. As a minumum you will
-# need to change the PROJECT, DOTVERSION and DLLOBJS variables to values

-MSG = ^
-You will need to run vcvars32.bat from Developer Studio, first, to setup^

-!error $(MSG)
-!endif
-
-#------------------------------------------------------------------------------
-# HOW TO USE this makefile:
-#
-# 1)  It is now necessary to have %MSVCDir% set in the environment.  This is
-#     used  as a check to see if vcvars32.bat had been run prior to running
-#     nmake or during the installation of Microsoft Visual C++, MSVCDir had
-#     been set globally and the PATH adjusted.  Either way is valid.
-#
-#     You'll need to run vcvars32.bat contained in the MsDev's vc(98)/bin
-#     directory to setup the proper environment, if needed, for your current
-#     setup.  This is a needed bootstrap requirement and allows the swapping of
-#     different environments to be easier.
-#
-# 2)  To use the Platform SDK (not expressly needed), run setenv.bat after
-#     vcvars32.bat according to the instructions for it.  This can also turn on
-#     the 64-bit compiler, if your SDK has it.
-#
-# 3)  Targets are:
-#	all       -- Builds everything.
-#       <project> -- Builds the project (eg: nmake sample)
-#	test      -- Builds and runs the test suite.
-#	install   -- Installs the built binaries and libraries to $(INSTALLDIR)
-#		     in an appropriate subdirectory.
-#	clean/realclean/distclean -- varying levels of cleaning.
-#
-# 4)  Macros usable on the commandline:
-#	INSTALLDIR=<path>
-#		Sets where to install Tcl from the built binaries.
-#		C:\Progra~1\Tcl is assumed when not specified.
-#
-#	OPTS=static,msvcrt,staticpkg,threads,symbols,profile,loimpact,none
-#		Sets special options for the core.  The default is for none.
-#		Any combination of the above may be used (comma separated).
-#		'none' will over-ride everything to nothing.
-#
-#		static  =  Builds a static library of the core instead of a
-#			   dll.  The shell will be static (and large), as well.
-#		msvcrt  =  Effects the static option only to switch it from
-#			   using libcmt(d) as the C runtime [by default] to
-#			   msvcrt(d). This is useful for static embedding
-#			   support.
-#		staticpkg = Effects the static option only to switch
-#			   tclshXX.exe to have the dde and reg extension linked
-#			   inside it.
-#		threads =  Turns on full multithreading support.
-#		thrdalloc = Use the thread allocator (shared global free pool).
-#		symbols =  Adds symbols for step debugging.
-#		profile =  Adds profiling hooks.  Map file is assumed.
-#		loimpact =  Adds a flag for how NT treats the heap to keep memory
-#			   in use, low.  This is said to impact alloc performance.
-#
-#	STATS=memdbg,compdbg,none
-#		Sets optional memory and bytecode compiler debugging code added
-#		to the core.  The default is for none.  Any combination of the
-#		above may be used (comma separated).  'none' will over-ride
-#		everything to nothing.
-#
-#		memdbg   = Enables the debugging memory allocator.
-#		compdbg  = Enables byte compilation logging.
-#
-#	MACHINE=(IX86|IA64|ALPHA)
-#		Set the machine type used for the compiler, linker, and
-#		resource compiler.  This hook is needed to tell the tools
-#		when alternate platforms are requested.  IX86 is the default
-#		when not specified.
-#
-#	TMP_DIR=<path>
-#	OUT_DIR=<path>
-#		Hooks to allow the intermediate and output directories to be
-#		changed.  $(OUT_DIR) is assumed to be 
-#		$(BINROOT)\(Release|Debug) based on if symbols are requested.
-#		$(TMP_DIR) will de $(OUT_DIR)\<buildtype> by default.
-#
-#	TESTPAT=<file>
-#		Reads the tests requested to be run from this file.
-#
-#	CFG_ENCODING=encoding
-#		name of encoding for configuration information. Defaults
-#		to cp1252
-#
-# 5)  Examples:
-#
-#	Basic syntax of calling nmake looks like this:
-#	nmake [-nologo] -f makefile.vc [target|macrodef [target|macrodef] [...]]
-#
-#                        Standard (no frills)
-#       c:\tcl_src\win\>c:\progra~1\micros~1\vc98\bin\vcvars32.bat
-#       Setting environment for using Microsoft Visual C++ tools.
-#       c:\tcl_src\win\>nmake -f makefile.vc all
-#       c:\tcl_src\win\>nmake -f makefile.vc install INSTALLDIR=c:\progra~1\tcl
-#
-#                         Building for Win64
-#       c:\tcl_src\win\>c:\progra~1\micros~1\vc98\bin\vcvars32.bat
-#       Setting environment for using Microsoft Visual C++ tools.
-#       c:\tcl_src\win\>c:\progra~1\platfo~1\setenv.bat /pre64 /RETAIL
-#       Targeting Windows pre64 RETAIL
-#       c:\tcl_src\win\>nmake -f makefile.vc MACHINE=IA64

+.Sh NAME
+.Nm hwt
+.Nd Hardware Trace Framework
+.Sh SYNOPSIS
+.Cd "options HWT_HOOKS"
+.Cd "device hwt"
+.Pp
+At least one of:
+.Cd "device intel_pt"
+.Pq amd64
+.Cd "device coresight"
+.Pq arm64
+.Cd "device spe"
+.Pq arm64
+.Pp
+In
+.Xr rc.conf 5 :
+.Cd kld_list="hwt"
+.Sh DESCRIPTION
+The
+.Nm
+framework provides infrastructure for hardware-assisted tracing.
+It collects detailed information about software execution and stores it as
+events in highly compressed format into DRAM.
+The events cover information about control flow changes of a program, whether
+branches taken or not, exceptions taken, timing information, cycles elapsed and
+more.
+The information collected allows to reconstruct entire program flow of a given
+application without noticeable performance impact.
+.Sh HARDWARE
+The framework supports several tracing technologies found on
+.Cd arm64
+and
+.Cd amd64
+systems:
+.Pp
+.Bl -bullet -compact
+.It
+ARM Coresight
+.It
+ARM Statistical Profiling Extension (SPE)
+.It
+Intel Processor Trace (PT)
+.El
+.Pp
+The
+.Nm
+framework supports two modes of operation:
+.Bl -tag -width "Thread mode"
+.It Em CPU mode
+Capture CPU activity in kernel mode.
+.It Em Thread mode
+Capture activity of each of a process's threads in user mode.
+.El
+.Sh MANAGEMENT
+When loaded into kernel, the
+.Nm
+framework provides
+.Pa /dev/hwt
+character device.
+The only
+.Xr ioctl 2
+request it accepts is
+.Dv HWT_IOC_ALLOC .
+This request allocates kernel tracing context (CTX) based on requested mode of
+operation, set of CPUs and/or pid.
+.Pp
+Upon successfull CTX allocation, the ioctl returns a CTX identification
+number (ident).
+.Pp
+Each CTX is then managed using its own dedicated character device found at
+.Pa "/dev/hwt_${ident}_${d}",
+where ident is a unique identification number of tracing context, d is either
+cpu_id (in HWT CPU mode) or process pid (in HWT Thread mode).
+.Sh HOOKS
+During tracing of a target process, HWT records runtime events such as threads
+creation, exec and mmap system calls.
+These events are logged as "records" within a particular CTX associated with
+traced process.
+.Pp
+Additionally, HWT can suspend the target thread upon exec or mmap system calls
+if requested by the user.
+This pause allows user-space tools to retrieve the records and adjust tracing
+settings before execution continues.
+This feature is especially useful when address range filtering is enabled,
+allowing tracing of specific functions within the target executable or a
+dynamic library.
+.Sh KERNEL OPTIONS
+The following options in the kernel configuration file are mandatory and
+related to
+.Nm
+operation:
+.Pp
+.Bl -tag -width ".Dv HWT_HOOKS" -compact
+.It Dv HWT_HOOKS
+Enable kernel hooks.
+.El
+.Sh IOCTL INTERFACE
+Once a CTX is allocated, it's management character device accepts several IOC
+requests:
+.Bl -tag -width "HWT_IOC_RECORD_GET"
+.It Dv HWT_IOC_START
+Start tracing.
+In HWT CPU mode the tracing does actually start with this
+.Xr ioctl 2
+request.
+In the Thread mode, the tracing "running" flag set, but tracing begins after
+scheduler switches the target thread onto CPU and return to user mode.
+.It Dv HWT_IOC_STOP
+Stop tracing of the particular CTX.
+.It Dv HWT_IOC_RECORD_GET
+Copy all or part of records collected during hook invocation and associated
+with this CTX to userspace.
+.It Dv HWT_IOC_BUFPTR_GET
+Get current pointer in buffer that is filled by tracing units in real-time.
+.It Dv HWT_IOC_SET_CONFIG
+Set achitecture-specific config (optional).
+.It Dv HWT_IOC_WAKEUP
+Wake up a thread that has been put to sleep by HWT framework hooks.
+.It Dv HWT_IOC_SVC_BUF
+For SPE-only, the kernel is waiting for userspace to notify that it's copied
+out a buffer to avoid data loss/overwriting buffers.
+.El
+.Sh SEE ALSO

+.Nd Solaris-like extended attribute system interface
+.Sh DESCRIPTION
+Description of the system interface for named attributes
+(the NFS Version 4 terminology).
+.Ss Introduction
+This document describes an alternate system interface for extended
+attributes as compared to
+.Xr extattr 2 .
+It is based on the interface provided by Solaris and NFS Version 4.
+.Pp
+This interface associates a directory, known as a named attribute directory,
+to a file system object.
+This directory is read in the same manner as a normal directory via the
+.Xr getdents 2
+or
+.Xr getdirentries 2
+system calls.
+The
+.Pa .\&
+and
+.Pa ..\&
+entries refer to the directory itself and to the associated file object,
+respectively.
+The other entries in this directory
+are the names of the extended attributes for the associated file object
+and are referred to as named attributes.
+These named attributes are regular files used to store the attribute's
+value.
+.Pp
+A named attribute directory does not live in the file system's name space.
+It is accessed via an
+.Xr open 2
+or
+.Xr openat 2
+system call done on a file to query the named attributes for the file,
+with the
+.Dv O_NAMEDATTR
+flag specified and a
+.Fa path
+argument of
+.Pa .\& .
+This file descriptor can be used as the
+.Fa fd
+argument for a variety of system calls, such as:
+.Xr fchdir 2 ,
+.Xr unlinkat 2
+and
+.Xr renameat 2 .
+.Xr renameat 2
+is only permitted to rename a named attribute within the same named
+attribute directory.
+.Pp
+When a file descriptor for a file object in the file system's namespace
+is used as the
+.Fa fd
+argument of an
+.Xr openat 2
+along with the
+.Fa flag
+.Dv O_NAMEDATTR
+and a
+.Fa path
+argument that is the name of a named attribute (not
+.Pa .\&
+or
+.Pa ..\&
+), a file descriptor for the named attribute is returned.
+If the
+.Fa flag
+.Dv O_CREAT
+is specified, the named attribute will be created if it does not exist.
+The
+.Fa path
+argument must be a single component name, with no embedded
+.Dq /
+in it.
+I/O on these named attribute file descriptors may be performed by
+standard I/O system calls
+such as:
+.Xr read 2 ,
+.Xr write 2 ,
+.Xr lseek 2
+and
+.Xr ftruncate 2 .
+.Pp
+The
+.Dv _PC_NAMEDATTR_ENABLED
+.Fa name
+argument to
+.Xr pathconf 2
+will return 1 if the file system supports named attributes.
+The
+.Dv _PC_HAS_NAMEDATTR
+.Fa name
+argument to
+.Xr pathconf 2
+will return 1 if there are one or more named attributes for the file.
+If an application does a
+.Xr openat 2
+of
+.Dq .\&
+to open a named attribute directory when no named attribute directory exists,
+an empty named attribute directory will be created.
+Testing
+.Dv _PC_HAS_NAMEDATTR
+can be done to avoid creating these named attribute directories unnecessarily.
+.Pp
+The named attribute interface is a different mechanism/system call interface for
+manipulating extended attributes compared with
+.Xr extattr 2 .
+Although the named attribute machanism might require different internal
+implementation
+of extended attributes within a file system, both ZFS and NFSv4 provide
+both mechanisms, which can be used interchangeably to manipulate
+extended attributes, but with a couple of limitations.
+.Bl -bullet
+.It
+The
+.Xr extattr 2
+interface requires that an extended attribute's value be set or acquired
+via a single system call using a single buffer.
+This limits the size of the attribute's value.
+.It
+The named attribute interface does not support system namespace
+extended attributes and,
+as such, system namespace extended attributes must be manipulated via
+.Xr extattr 2 .
+.El
+.Pp
+The named attribute mechanism/system call interface provides certain
+advantages over
+.Xr extattr 2 .
+Since the attribute's value is updated via
+.Xr read 2
+and
+.Xr write 2
+system calls, the attribute's data may be as large as any regular file
+and may be partially updated.
+(Note that this interface does not provide the atomicity guarantee that
+.Xr extattr 2
+does.)
+The permission to access a named attribute directory is determined from
+the access control information for the associated file object.
+However, access control information can be set on each individual attribute
+in a manner similar to a regular file.
+This provides
+.Dq per attribute
+granular control over attribute permissions via
+.Xr fchown 2 .
+.Pp
+At this time, the only local file system which supports this interface
+is ZFS and only if the
+.Dv xattr
+property is set to
+.Dq dir .
+(Note that, even when
+.Dq zfs get xattr <file-system>
+shows
+.Dq on
+the command
+.Dq zfs set xattr=dir <file-system>
+must be done, followed by a remount to make the setting take effect.)
+A NFSv4 mount will also support this interface, but only if the NFSv4
+server file system supports named attributes (the openattr operation).
+The
+.Fx
+NFSv4 server supports named attributes only
+for ZFS exported file systems where the
+.Dq xattr
+property is set to
+.Dq dir
+for the file system.
