All of the source code for fossil is contained in the src/ subdirectory.
But there is a lot of generated code, so you will probably want to
use the Makefile.  To do a complete build on unix, just type:

   make










On a windows box, use one of the Makefiles in the win/ subdirectory,
according to your compiler and environment.  For example:



   make -f win/Makefile.w32





If you have trouble, or you want to do something fancy, just look at
top level makefile. There are 6 configuration options that are all well
commented. Instead of editing the Makefile, consider copying the Makefile
to an alternative name such as "GNUMakefile", "BSDMakefile", or "makefile"
and editing the copy.


BUILDING OUTSIDE THE SOURCE TREE

An out of source build is pretty easy:

  1. Make a new directory to do the builds in.
  2. Copy "Makefile" from the source into the build directory and
  modify the SRCDIR macro along the lines of:

    SRCDIR=../src




  3. type: "make"

This will now keep all generates files seperate from the maintained
source code.

--------------------------------------------------------------------------

Here are some notes on what is happening behind the scenes:





* The Makefile just sets up a few macros and then invokes the
  real makefile in src/main.mk.  The src/main.mk makefile is
  automatically generated by a TCL script found at src/makemake.tcl.
  Do not edit src/main.mk directly.  Update src/makemake.tcl and
  then rerun it.

* The *.h header files are automatically generated using a program
  called "makeheaders".  Source code to the makeheaders program is
  found in src/makeheaders.c.  Documentation is found in 
  src/makeheaders.html.

* Most *.c source files are preprocessed using a program called
  "translate".  The sources to translate are found in src/translate.c.
  A header comment in src/translate.c explains in detail what it does.

* The src/mkindex.c program generates some C code that implements
  static lookup tables.  See the header comment in the source code
  for details on what it does.

To do a complete build, just type:

   ./configure; make

The ./configure script builds Makefile from Makefile.in based on
your system and any options you select (run "./configure --help"
for a listing of the available options.)

If you wish to use the original Makefile with no configuration, you can
instead use:

   make -f Makefile.classic

On a windows box, use one of the Makefiles in the win/ subdirectory,
according to your compiler and environment.  If you have MinGW or
MinGW-w64 installed on your system (Msys or Cygwin, or as
cross-compile environment on Linux or Darwin), then consider:

   make -f win/Makefile.mingw

If you have VC++ installed on your system, then consider:

   cd win; nmake /f Makefile.msc

If you have trouble, or you want to do something fancy, just look at
Makefile.classic. There are 6 configuration options that are all well
commented. Instead of editing the Makefile.classic, consider copying
Makefile.classic to an alternative name such as "GNUMakefile",
"BSDMakefile", or "makefile" and editing the copy.


BUILDING OUTSIDE THE SOURCE TREE

An out of source build is pretty easy:

  1. Make and change to a new directory to do the builds in.
  2. Run the "configure" script from this directory.
  3. Type: "make"

For example:

  mkdir build
  cd build
  ../configure
  make

This will now keep all generates files separate from the maintained
source code.

--------------------------------------------------------------------------

Here are some notes on what is happening behind the scenes:

* The configure script (if used) examines the options given
  and runs various tests with the C compiler to create Makefile
  from the Makefile.in template as well as autoconfig.h

* The Makefile just sets up a few macros and then invokes the
  real makefile in src/main.mk.  The src/main.mk makefile is
  automatically generated by a TCL script found at src/makemake.tcl.
  Do not edit src/main.mk directly.  Update src/makemake.tcl and
  then rerun it.

* The *.h header files are automatically generated using a program
  called "makeheaders".  Source code to the makeheaders program is
  found in src/makeheaders.c.  Documentation is found in
  src/makeheaders.html.

* Most *.c source files are preprocessed using a program called
  "translate".  The sources to translate are found in src/translate.c.
  A header comment in src/translate.c explains in detail what it does.

* The src/mkindex.c program generates some C code that implements
  static lookup tables.  See the header comment in the source code
  for details on what it does.

# Automatically reconfigure whenever an autosetup file or one of the
# make source files change.
#
# The "touch" is necessary to avoid a make loop due to a new upstream
# feature in autosetup (GH 0a71e3c3b7) which rewrites *.in outputs only
# if doing so will write different contents; otherwise, it leaves them
# alone so the mtime doesn't change.  This means that if you change one
# our depdendencies besides Makefile.in, we'll reconfigure but Makefile
# won't change, so this rule will remain out of date, so we'll reconfig
# but Makefile won't change, so we'll reconfig but... endlessly.
#
# This is also why we repeat the reconfig target's command here instead
# of delegating to it with "$(MAKE) reconfig": having children running
# around interfering makes this failure mode even worse.

#!/usr/bin/make
#
# This is a specially modified version of the Makefile that will build
# Fossil on Mac OSX Jaguar (10.2) circa 2002.  This Makefile is used for
# testing on an old PPC iBook.  The use of this old platform helps to verify
# Fossil and SQLite running on big-endian hardware.
#
# To build with this Makefile, run:
#
#     make -f Makefile.osx-jaguar
#
#
# This is the top-level makefile for Fossil when the build is occurring
# on a unix platform.  This works out-of-the-box on most unix platforms.
# But you are free to vary some of the definitions if desired.
#
#### The toplevel directory of the source tree.  Fossil can be built
#    in a directory that is separate from the source tree.  Just change
#    the following to point from the build directory to the src/ folder.
#
SRCDIR = ./src

#### The directory into which object code files should be written.
#    Having a "./" prefix in the value of this variable breaks our use of the
#    "makeheaders" tool when running make on the MinGW platform, apparently
#    due to some command line argument manipulation performed automatically
#    by the shell.
#
#
OBJDIR = bld

#### C Compiler and options for use in building executables that
#    will run on the platform that is doing the build.  This is used
#    to compile code-generator programs as part of the build process.
#    See TCC below for the C compiler for building the finished binary.
#
BCC = cc
BCCFLAGS = $(CFLAGS)

#### The suffix to add to final executable file.  When cross-compiling
#    to windows, make this ".exe".  Otherwise leave it blank.
#
E = 

TCC = cc
TCCFLAGS = $(CFLAGS)

#### Tcl shell for use in running the fossil testsuite.  If you do not
#    care about testing the end result, this can be blank.

This is the README for how to set up the Fossil/JSON test web page
under Apache on Unix systems. This is only intended only for
Fossil/JSON developers/tinkerers:

First, copy cgi-bin/fossil-json.cgi.example to
cgi-bin/fossil-json.cgi.  Edit it and correct the paths to the fossil
binary and the repo you want to serve. Make it executable.

MAKE SURE that the fossil repo you use is world-writable OR that your
Web/CGI server is set up to run as the user ID of the owner of the
fossil file. ALSO: the DIRECTORY CONTAINING the repo file must be
writable by the CGI process.

Next, set up an apache vhost entry. Mine looks like:

<VirtualHost *:80>
    ServerAlias fjson
    ScriptAlias /cgi-bin/ /home/stephan/cvs/fossil/fossil-json/ajax/cgi-bin/
    DocumentRoot /home/stephan/cvs/fossil/fossil-json/ajax
</VirtualHost>

Now add your preferred vhost name (fjson in the above example) to /etc/hosts:

  127.0.0.1 ...other aliases... fjson

Restart your Apache.

Now visit: http://fjson/

that will show the test/demo page. If it doesn't, edit index.html and
make sure that:

  WhAjaj.Connector.options.ajax.url = ...;

points to your CGI script. In theory you can also do this over fossil
standalone server mode, but i haven't yet tested that particular test
page in that mode.

Added ajax/cgi-bin/fossil-json.cgi.example.

/**
    EXPERIMENTAL concrete WhAjaj.Connector.sendImpl() implementation which
    uses Rhino to connect to a local fossil binary for input and output. Its
    signature and semantics are as described for
    WhAjaj.Connector.prototype.sendImpl(), with a few exceptions and
    additions:

    - It does not support timeouts or asynchronous mode.

    - The args.fossilBinary property must point to the local fossil binary
    (it need not be a complete path if fossil is in the $PATH). This
    function throws (without calling any request callbacks) if
    args.fossilBinary is not set. fossilBinary may be set on
    WhAjaj.Connector.options.ajax, in the FossilAjaj constructor call, as
    the ajax options parameter to any of the FossilAjaj.sendCommand() family
    of functions, or by setting
    aFossilAjajInstance.ajaj.options.fossilBinary on a specific
    FossilAjaj instance.

    - It uses the args.url field to create the "command" property of the
    request, constructs a request envelope, spawns a fossil process in JSON
    mode, feeds it the request envelope, and returns the response envelope
    via the same mechanisms defined for the HTTP-based implementations.

    The interface is otherwise compatible with the "normal"
    FossilAjaj.sendCommand() front-end (it is, however, fossil-specific, and
    not back-end agnostic like the WhAjaj.sendImpl() interface intends).

    Public Domain.

    NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK.

    See http://www.JSON.org/js.html

    This file creates a global JSON object containing two methods: stringify
    and parse.

        JSON.stringify(value, replacer, space)
            value       any JavaScript value, usually an object or array.

            replacer    an optional parameter that determines how object
                        values are stringified for objects. It can be a
                        function or an array of strings.

            space       an optional parameter that specifies the indentation
                        of nested structures. If it is omitted, the text will
                        be packed without extra whitespace. If it is a number,
                        it will specify the number of spaces to indent at each
                        level. If it is a string (such as '\t' or '&nbsp;'),
                        it contains the characters used to indent at each level.

            This method produces a JSON text from a JavaScript value.

            When an object value is found, if the object contains a toJSON
            method, its toJSON method will be called and the result will be
            stringified. A toJSON method does not serialize: it returns the
            value represented by the name/value pair that should be serialized,
            or undefined if nothing should be serialized. The toJSON method
            will be passed the key associated with the value, and this will be
            bound to the object holding the key.

            For example, this would serialize Dates as ISO strings.

                Date.prototype.toJSON = function (key) {
                    function f(n) {
                        // Format integers to have at least two digits.
                        return n < 10 ? '0' + n : n;
                    }

                    return this.getUTCFullYear()   + '-' +
                         f(this.getUTCMonth() + 1) + '-' +
                         f(this.getUTCDate())      + 'T' +
                         f(this.getUTCHours())     + ':' +
                         f(this.getUTCMinutes())   + ':' +
                         f(this.getUTCSeconds())   + 'Z';
                };

            You can provide an optional replacer method. It will be passed the
            key and value of each member, with this bound to the containing
            object. The value that is returned from your method will be
            serialized. If your method returns undefined, then the member will
            be excluded from the serialization.

            If the replacer parameter is an array of strings, then it will be
            used to select the members to be serialized. It filters the results
            such that only members with keys listed in the replacer array are
            stringified.

            Values that do not have JSON representations, such as undefined or
            functions, will not be serialized. Such values in objects will be
            dropped; in arrays they will be replaced with null. You can use
            a replacer function to replace those with JSON values.
            JSON.stringify(undefined) returns undefined.

            The optional space parameter produces a stringification of the
            value that is filled with line breaks and indentation to make it
            easier to read.

            If the space parameter is a non-empty string, then that string will
            be used for indentation. If the space parameter is a number, then
            the indentation will be that many spaces.

            Example:

            text = JSON.stringify(['e', {pluribus: 'unum'}]);
            // text is '["e",{"pluribus":"unum"}]'


            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'

            text = JSON.stringify([new Date()], function (key, value) {
                return this[key] instanceof Date ?
                    'Date(' + this[key] + ')' : value;
            });
            // text is '["Date(---current time---)"]'


        JSON.parse(text, reviver)
            This method parses a JSON text to produce an object or array.
            It can throw a SyntaxError exception.

            The optional reviver parameter is a function that can filter and
            transform the results. It receives each of the keys and values,
            and its return value is used instead of the original value.
            If it returns what it received, then the structure is not modified.
            If it returns undefined then the member is deleted.

            Example:

            // Parse the text. Values that look like ISO date strings will
            // be converted to Date objects.

            myData = JSON.parse(text, function (key, value) {
                var a;
                if (typeof value === 'string') {
                    a =
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
                    if (a) {
                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
                            +a[5], +a[6]));
                    }
                }
                return value;
            });

            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
                var d;
                if (typeof value === 'string' &&
                        value.slice(0, 5) === 'Date(' &&
                        value.slice(-1) === ')') {
                    d = new Date(value.slice(5, -1));
                    if (d) {
                        return d;
                    }

/**
    This file provides a JS interface into the core functionality of
    JSON-centric back-ends. It sends GET or JSON POST requests to
    a back-end and expects JSON responses. The exact semantics of
    the underlying back-end and overlying front-end are not its concern,
    and it leaves the interpretation of the data up to the client/server
    insofar as possible.

    All functionality is part of a class named WhAjaj, and that class
    acts as namespace for this framework.

    http://whiki.wanderinghorse.net, where it contained quite a bit
    of application-specific logic. It was eventually (the 3rd time i

/**
    Each instance of this class holds state information for making
    AJAJ requests to a back-end system. While clients may use one
    "requester" object per connection attempt, for connections to the
    same back-end, using an instance configured for that back-end
    can simplify usage. This class is designed so that the actual
    connection-related details (i.e. _how_ it connects to the
    back-end) may be re-implemented to use a client's preferred
    connection mechanism (e.g. jQuery).

    The optional opt parameter may be an object with any (or all) of
    the properties documented for WhAjaj.Connector.options.ajax.
    Properties set here (or later via modification of the "options"
    property of this object) will be used in calls to
    WhAjaj.Connector.sendRequest(), and these override (normally) any
    options set in WhAjaj.Connector.options.ajax. Note that
    WhAjaj.Connector.sendRequest() _also_ takes an options object,
    and ones passed there will override, for purposes of that one
    request, any options passed in here or defined in
    WhAjaj.Connector.options.ajax. See WhAjaj.Connector.options.ajax
    and WhAjaj.Connector.prototype.sendRequest() for more details
    about the precedence of options.

    Sample usage:

    @code
    // Set up common connection-level options:
    var cgi = new WhAjaj.Connector({
        url: '/cgi-bin/my.cgi',
        timeout:10000,
        onResponse(resp,req) { alert(JSON.stringify(resp,0.4)); },
        onError(req,opt) {
            alert(opt.errorMessage);
        }
    });
    // Any of those options may optionally be set globally in
    // WhAjaj.Connector.options.ajax (onError(), beforeSend(), and afterSend()
    // are often easiest/most useful to set globally).

    // Get list of pages...
    cgi.sendRequest( null, {
        onResponse(resp,req){ alert(WhAjaj.stringify(resp)); }
    });
    @endcode

    For common request types, clients can add functions to this
    object which act as wrappers for backend-specific functionality. As
    a simple example:

    @code
    cgi.login = function(name,pw,ajajOpt) {
        this.sendRequest(
            {command:"json/login",
              name:name,
              password:pw
            }, ajajOpt );
    };
    @endcode

    TODOs:

    - Caching of page-load requests, with a configurable lifetime.

    - Use-cases like the above login() function are a tiny bit
    problematic to implement when each request has a different URL
    path (i know this from the whiki and fossil implementations).
    This is partly a side-effect of design descisions made back in
    the very first days of this code's life. i need to go through
    and see where i can bend those conventions a bit (where it won't
    break my other apps unduly).
*/
WhAjaj.Connector = function(opt)
{
    if(WhAjaj.isObject(opt)) this.options = opt;
    //TODO?: this.$cache = {};
};

/**
    The core options used by WhAjaj.Connector instances for performing
    network operations. These options can (and some _should_)
    be changed by a client application. They can also be changed
    on specific instances of WhAjaj.Connector, but for most applications
    it is simpler to set them here and not have to bother with configuring
    each WhAjaj.Connector instance. Apps which use multiple back-ends at one time,
    however, will need to customize each instance for a given back-end.
*/
WhAjaj.Connector.options = {
    /**
        A (meaningless) prefix to apply to WhAjaj.Connector-generated
        request IDs.
    */
    requestIdPrefix:'WhAjaj.Connector-',
    /**
        Default options for WhAjaj.Connector.sendRequest() connection
        parameters. This object holds only connection-related
        options and callbacks (all optional), and not options
        related to the required JSON structure of any given request.
        i.e. the page name used in a get-page request are not set
        here but are specified as part of the request object.

        These connection options are a "normalized form" of options
        often found in various AJAX libraries like jQuery,
        Prototype, dojo, etc. This approach allows us to swap out
        the real connection-related parts by writing a simple proxy
        which transforms our "normalized" form to the
        backend-specific form. For examples, see the various
        implementations stored in WhAjaj.Connector.sendImpls.

        The following callback options are, in practice, almost
        always set globally to some app-wide defaults:

        - onError() to report errors using a common mechanism.
        - beforeSend() to start a visual activity notification
        - afterSend() to disable the visual activity notification

        However, be aware that if any given WhAjaj.Connector instance is
        given its own before/afterSend callback then those will
        override these. Mixing shared/global and per-instance
        callbacks can potentially lead to confusing results if, e.g.,
        the beforeSend() and afterSend() functions have side-effects
        but are not used with their proper before/after partner.

        TODO: rename this to 'ajaj' (the name is historical). The
        problem with renaming it is is that the word 'ajax' is
        pretty prevelant in the source tree, so i can't globally
        swap it out.

        - If resp is-a String and opt.jsonp then resp is assumed to be
        a JSONP-form construct and is eval()d BEFORE opt.onResponse()
        is called. It is arguable to eval() it first, but the logic
        integrates better with the non-jsonp handler.

        The sendImpl() should return immediately after calling this.

        The sendImpl() must call only one of onSendSuccess() or

    Historical notes:

    a) We once had an implementation based on Prototype, but that
    library just pisses me off (they change base-most types'
    prototypes, introducing side-effects in client code which
    doesn't even use Prototype). The Prototype version at the time
    had a serious toJSON() bug which caused empty arrays to
    serialize as the string "[]", which broke a bunch of my code.
    (That has been fixed in the mean time, but i don't use
    Prototype.)

    b) We once had an implementation for the dojo library,

    If/when the time comes to add Prototype/dojo support, we simply
    need to port:

    http://code.google.com/p/jsonmessage/source/browse/trunk/lib/JSONMessage/JSONMessage.inc.js

    (search that file for "dojo" and "Prototype") to this tree. That
    code is this code's generic grandfather and they are still very
    similar, so a port is trivial.

        Limitations vis-a-vis the interface:

        - timeouts are not supported.

        - asynchronous mode is not supported because implementing it
        requires the ability to kill a running thread (which is deprecated

        TODOs:

        - add socket timeouts.

        - support HTTP proxy.

        The Java APIs support this, it just hasn't been added here yet.

/**
    This is the generic interface for making calls to a back-end
    JSON-producing request handler. It is a simple wrapper around
    WhAjaj.Connector.prototype.sendImpl(), which just normalizes the
    connection options for sendImpl() and makes sure that
    opt.beforeSend() is (possibly) called.

    The request parameter must either be false/null/empty or a
    fully-populated JSON-able request object (which will be sent as
    unencoded application/json text), depending on the type of
    request being made. It is never semantically legal (in this API)
    for request to be a string/number/true/array value. As a rule,
    only POST requests use the request data. GET requests should
    encode their data in opt.url or opt.urlParam (see below).

    opt must contain the network-related parameters for the request.
    Paramters _not_ set in opt are pulled from this.options or
    WhAjaj.Connector.options.ajax (in that order, using the first
    value it finds). Thus the set of connection-level options used
    for the request are a superset of those various sources.

    The "normalized" (or "superimposed") opt object's URL may be
    modified before the request is sent, as follows:

    if opt.urlParam is a string then it is assumed to be properly
    URL-encoded parameters and is appended to the opt.url. If it is
    an Object then it is assumed to be a one-dimensional set of
    key/value pairs with simple values (numbers, strings, booleans,
    null, and NOT objects/arrays). The keys/values are URL-encoded
    and appended to the URL.

    The beforeSend() callback (see below) can modify the options
    object before the request attempt is made.

    The callbacks in the normalized opt object will be triggered as
    follows (if they are set to Function values):

    - beforeSend(request,opt) will be called before any network
    processing starts. If beforeSend() throws then no other
    callbacks are triggered and this function propagates the
    exception. This function is passed normalized connection options
    as its second parameter, and changes this function makes to that
    object _will_ be used for the pending connection attempt.

    - onError(request,opt) will be called if a connection to the
    back-end cannot be established. It will be passed the original
    request object (which might be null, depending on the request
    type) and the normalized options object. In the error case, the
    opt object passed to onError() "should" have a property called
    "errorMessage" which contains a description of the problem.

    - onError(request,opt) will also be called if connection
    succeeds but the response is not JSON data.

    - onResponse(response,request) will be called if the response
    returns JSON data. That data might hold an error response code -
    clients need to check for that. It is passed the response object
    (a plain object) and the original request object.

    - afterSend(request,opt) will be called directly after the
    AJAX request is finished, before onError() or onResonse() are
    called. Possible TODO: we explicitly do NOT pass the response to
    this function in order to keep the line between the responsibilities
    of the various callback clear (otherwise this could be used the same
    as onResponse()). In practice it would sometimes be useful have the
    response passed to this function, mainly for logging/debugging
    purposes.

    The return value from this function is meaningless because
    AJAX operations tend to take place asynchronously.

# A boolean option is of the form:
#
## name[=0|1]  => "Description of this boolean option"
#
# The default is name=0, meaning that the option is disabled by default.
# If name=1 is used to make the option enabled by default, the description should reflect
# that with text like "Disable support for ...".
#
# An argument option (one which takes a parameter) is of the form:
#
## name:[=]value  => "Description of this option"
#
# If the name:value form is used, the value must be provided with the option (as --name=myvalue).
# If the name:=value form is used, the value is optional and the given value is used as the default
# if it is not provided.
#
# Undocumented options are also supported by omitting the "=> description.
# These options are not displayed with --help and can be useful for internal options or as aliases.

# For example, --disable-lfs is an alias for --disable=largefile:

# @synopsis:
#
# The 'cc-shared' module provides support for shared libraries and shared objects.
# It defines the following variables:
#
## SH_CFLAGS         Flags to use compiling sources destined for a shared library
## SH_LDFLAGS        Flags to use linking (creating) a shared library
## SH_SOPREFIX       Prefix to use to set the soname when creating a shared library
## SH_SOEXT          Extension for shared libs
## SH_SOEXTVER       Format for versioned shared libs - %s = version
## SHOBJ_CFLAGS      Flags to use compiling sources destined for a shared object
## SHOBJ_LDFLAGS     Flags to use linking a shared object, undefined symbols allowed
## SHOBJ_LDFLAGS_R   - as above, but all symbols must be resolved
## SH_LINKFLAGS      Flags to use linking an executable which will load shared objects
## LD_LIBRARY_PATH   Environment variable which specifies path to shared libraries
## STRIPLIBFLAGS     Arguments to strip a dynamic library

# @synopsis:
#
# The 'cc' module supports checking various 'features' of the C or C++
# compiler/linker environment. Common commands are cc-check-includes,
# cc-check-types, cc-check-functions, cc-with, make-autoconf-h and make-template.
#
# The following environment variables are used if set:
#
## CC       - C compiler
## CXX      - C++ compiler
## CCACHE   - Set to "none" to disable automatic use of ccache
## CFLAGS   - Additional C compiler flags
## CXXFLAGS - Additional C++ compiler flags
## LDFLAGS  - Additional compiler flags during linking
## LIBS     - Additional libraries to use (for all tests)
## CROSS    - Tool prefix for cross compilation
#
# The following variables are defined from the corresponding
# environment variables if set.
#
## CPPFLAGS
## LINKFLAGS
## CC_FOR_BUILD
## LD

# Configuration subroutine to validate and canonicalize a configuration type.
# Supply the specified configuration type as an argument.
# If it is invalid, we print an error message on stderr and exit with code 1.
# Otherwise, we print the canonical config type on stdout and succeed.

# You can get the latest version of this script from:
# http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD

# This file is supposed to be the same for all GNU packages
# and recognize all the CPU types, system types and aliases
# that are meaningful with *any* GNU software.
# Each package is responsible for reporting which valid configurations
# it does not support.  The user should be able to distinguish
# a failure to support a valid configuration from a meaningless
# configuration.

# The goal of this file is to map all the various variations of a given
# machine specification into a single specification in the form:
#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or in some cases, the newer four-part form:
#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# It is wrong to echo any other type of specification.

# @synopsis:
#
# The 'pkg-config' module allows package information to be found via pkg-config
#
# If not cross-compiling, the package path should be determined automatically
# by pkg-config.
# If cross-compiling, the default package path is the compiler sysroot.
# If the C compiler doesn't support -print-sysroot, the path can be supplied
# by the --sysroot option or by defining SYSROOT.
#
# PKG_CONFIG may be set to use an alternative to pkg-config

use cc

module-options {
	sysroot:dir => "Override compiler sysroot for pkg-config search path"
}

# @pkg-config-init ?required?
#
# Initialises the pkg-config system. Unless required is set to 0,
# it is a fatal error if the pkg-config
# This command will normally be called automatically as required,
# but it may be invoked explicitly if lack of pkg-config is acceptable.
#

#
# It defines the following variables, based on --prefix unless overridden by the user:
#
## datadir
## sysconfdir
## sharedstatedir
## localstatedir
## infodir
## mandir
## includedir

# Do "define defaultprefix myvalue" to set the default prefix *before* the first "use"
set defaultprefix [get-define defaultprefix /usr/local]

First experimental codes ...

tools/import-cvs.tcl
tools/lib/rcsparser.tcl

No actual import, right now only working on getting csets right. The
code uses CVSROOT/history as foundation, and augments that with data
from the individual RCS files (commit messages).

Statistics of a run ...
	3516 csets.

	1545 breaks on user change
	 558 breaks on file duplicate
	  13 breaks on branch/trunk change
	1402 breaks on commit message change

Time statistics ...
	3297 were processed in <= 1 seconds (93.77%)
	 217 were processed in between 2 seconds and 14 minutes.
	   1 was  processed in ~41 minutes
	   1 was  processed in ~22 hours

Time fuzz - Differences between csets range from 0 seconds to 66
days. Needs stats analysis to see if there is an obvious break. Even
so the times within csets and between csets overlap a great deal,
making time a bad criterium for cset separation, IMHO.

Leaving that topic, back to the current cset separator ...

It has a problem:
	The history file is not starting at the root!

Examples:
	The first three changesets are

	=============================/user
	M {Wed Nov 22 09:28:49 AM PST 2000} ericm 1.4 tcllib/modules/ftpd/ChangeLog
	M {Wed Nov 22 09:28:49 AM PST 2000} ericm 1.7 tcllib/modules/ftpd/ftpd.tcl
	files: 2
	delta: 0
	range: 0 seconds
	=============================/cmsg
	M {Wed Nov 29 02:14:33 PM PST 2000} ericm 1.3 tcllib/aclocal.m4
	files: 1
	delta: 
	range: 0 seconds
	=============================/cmsg
	M {Sun Feb 04 12:28:35 AM PST 2001} ericm 1.9 tcllib/modules/mime/ChangeLog
	M {Sun Feb 04 12:28:35 AM PST 2001} ericm 1.12 tcllib/modules/mime/mime.tcl
	files: 2
	delta: 0
	range: 0 seconds

All csets modify files which already have several revisions. We have
no csets from before that in the history, but these csets are in the
RCS files.

I wonder, is SF maybe removing old entries from the history when it
grows too large ?

This also affects incremental import ... I cannot assume that the
history always grows. It may shrink ... I cannot keep an offset, will
have to record the time of the last entry, or even the full entry
processed last, to allow me to skip ahead to anything not known yet.

I might have to try to implement the algorithm outlined below,
matching the revision trees of the individual RCS files to each other
to form the global tree of revisions. Maybe we can use the history to
help in the matchup, for the parts where we do have it.

Wait. This might be easier ... Take the delta information from the RCS
files and generate a fake history ... Actually, this might even allow
us to create a total history ... No, not quite, the merge entries the
actual history may contain will be missing. These we can mix in from
the actual history, as much as we have.

Still, lets try that, a fake history, and then run this script on it
to see if/where are differences.

===============================================================================


Notes about CVS import, regarding CVS.

- Problem: CVS does not really track changesets, but only individual
  revisions of files. To recover changesets it is necessary to look at
  author, branch, timestamp information, and the commit messages. Even
  so this is only heuristic, not foolproof.

  Existing tool: cvsps.

  Processes the output of 'cvs log' to recover changesets. Problem:
  Sees only a linear list of revisions, does not see branchpoints,
  etc. Cannot use the tree structure to help in making the decisions.

- Problem: CVS does not track merge-points at all. Recovery through
  heuristics is brittle at best, looking for keywords in commit
  messages which might indicate that a branch was merged with some
  other.


Ideas regarding an algorithm to recover changesets.

Key feature: Uses the per-file revision trees to help in uncovering
the underlying changesets and global revision tree G.

The per-file revision tree for a file X is in essence the global
revision tree with all nodes not pertaining to X removed from it. In
the reverse this allows us to built up the global revision tree from
the per-file trees by matching nodes to each other and extending.

Start with the per file revision tree of a single file as initial
approximation of the global tree. All nodes of this tree refer to the
revision of the file belonging to it, and through that the file
itself. At each step the global tree contains the nodes for a finite
set of files, and all nodes in the tree refer to revisions of all
files in the set, making the mapping total.

To add a file X to the tree take the per-file revision tree R and
performs the following actions:

- For each node N in R use the tuple <author, branch, commit message>
  to identify a set of nodes in G which may match N. Use the timestamp
  to locate the node nearest in time.

- This process will leave nodes in N unmapped. If there are unmapped
  nodes which have no neighbouring mapped nodes we have to
  abort.

  Otherwise take the nodes which have mapped neighbours. Trace the
  edges and see which of these nodes are connected in the local
  tree. Then look at the identified neighbours and trace their
  connections.

  If two global nodes have a direct connection, but a multi-edge
  connection in the local tree insert global nodes mapping to the
  local nodes and map them together. This expands the global tree to
  hold the revisions added by the new file.

  Otherwise, both sides have multi-edge connections then abort. This
  looks like a merge of two different branches, but there are no such
  in CVS ... Wait ... sort the nodes over time and fit the new nodes
  in between the other nodes, per the timestamps. We have overlapping
  / alternating changes to one file and others.

  A last possibility is that a node is only connected to a mapped
  parent. This may be a new branch, or again an alternating change on
  the given line. Symbols on the revisions will help to map this.

- We now have an extended global tree which incorporates the revisions
  of the new file. However new nodes will refer only to the new file,
  and old nodes may not refer to the new file. This has to be fixed,
  as all nodes have to refer to all files.

  Run over the tree and look at each parent/child pair. If a file is
  not referenced in the child, but the parent, then copy a reference
  to the file revision on the parent forward to the child. This
  signals that the file did not change in the given revision.

- After all files have been integrated in this manner we have global
  revision tree capturing all changesets, including the unchanged
  files per changeset.


This algorithm has to be refined to also take Attic/ files into
account.

-------------------------------------------------------------------------

Two archive files mapping to the same user file. How are they
interleaved ?

(a)	sqlite/src/os_unix.h,v
(b)	sqlite/src/Attic/os_unix.h,v

Problem: Max version of (a) is 1.9
	 Max version of (b) is 1.11
	 cvs co 1.10 -> no longer in the repository.

This seems to indicate that the non-Attic file is relevant.

--------------------------------------------------------------------------

tcllib - more problems - tklib/pie.tcl,v -

invalid change text in
/home/aku/Projects/Tcl/Fossil/Devel/Examples/cvs-tcllib/tklib/modules/tkpiechart/pie.tcl,v

Possibly braces ?

To perform CVS imports for fossil we need at least the ability to
parse CVS files, i.e. RCS files, with slight differences.

For the general architecture of the import facility we have two major
paths to choose between.

One is to use an external tool which processes a cvs repository and
drives fossil through its CLI to insert the found changesets.

The other is to integrate the whole facility into the fossil binary
itself.

I dislike the second choice. It may be faster, as the implementation
can use all internal functionality of fossil to perform the import,
however it will also bloat the binary with functionality not needed
most of the time. Which becomes especially obvious if more importers
are to be written, like for monotone, bazaar, mercurial, bitkeeper,
git, SVN, Arc, etc. Keeping all this out of the core fossil binary is
IMHO more beneficial in the long term, also from a maintenance point
of view. The tools can evolve separately. Especially important for CVS
as it will have to deal with lots of broken repositories, all
different.

However, nothing speaks against looking for common parts in all
possible import tools, and having these in the fossil core, as a
general backend all importer may use. Something like that has already
been proposed: The deconstruct|reconstruct methods. For us, actually
only reconstruct is important. Taking an unordered collection of files
(data, and manifests) it generates a proper fossil repository.  With
that method implemented all import tools only have to generate the
necessary collection and then leave the main work of filling the
database to fossil itself.

The disadvantage of this method is however that it will gobble up a
lot of temporary space in the filesystem to hold all unique revisions
of all files in their expanded form.

It might be worthwhile to consider an extension of 'reconstruct' which
is able to incrementally add a set of files to an existing fossil
repository already containing revisions. In that case the import tool
can be changed to incrementally generate the collection for a
particular revision, import it, and iterate over all revisions in the
origin repository. This is of course also dependent on the origin
repository itself, how well it supports such incremental export.

This also leads to a possible method for performing the import using
only existing functionality ('reconstruct' has not been implemented
yet). Instead generating an unordered collection for each revision
generate a properly setup workspace, simply commit it. This will
require use of rm, add and update methods as well, to remove old and
enter new files, and point the fossil repository to the correct parent
revision from the new revision is derived.

The relative efficiency (in time) of these incremental methods versus
importing a complete collection of files encoding the entire origin
repository however is not clear.

----------------------------------

reconstruct

The core logic for handling content is in the file "content.c", in
particular the functions 'content_put' and 'content_deltify'. One of
the main users of these functions is in the file "checkin.c", see the
function 'commit_cmd'.

The logic is clear. The new modified files are simply stored without
delta-compression, using 'content_put'. And should fosssil have an id
for the _previous_ revision of the committed file it uses
'content_deltify' to convert the already stored data for that revision
into a delta with the just stored new revision as origin.

In other words, fossil produces reverse deltas, with leaf revisions
stored just zip-compressed (plain) and older revisions using both zip-
and delta-compression.

Of note is that the underlying logic in 'content_deltify' gives up on
delta compression if the involved files are either not large enough,
or if the achieved compression factor was not high enough. In that
case the old revision of the file is left plain.

The scheme can thus be called a 'truncated reverse delta'.

The manifest is created and committed after the modified files. It
uses the same logic as for the regular files. The new leaf is stored
plain, and storage of the parent manifest is modified to be a delta
with the current as origin.

Further note that for a checkin of a merge result oonly the primary
parent is modified in that way. The secondary parent, the one merged
into the current revision is not touched. I.e. from the storage layer
point of view this revision is still a leaf and the data is kept
stored plain, not delta-compressed.



Now the "reconstruct" can be done like so:

- Scan the files in the indicated directory, and look for a manifest.

- When the manifest has been found parse its contents and follow the
  chain of parent links to locate the root manifest (no parent).

- Import the files referenced by the root manifest, then the manifest
  itself. This can be done using a modified form of the 'commit_cmd'
  which does not have to construct a manifest on its own from vfile,
  vmerge, etc.

- After that recursively apply the import of the previous step to the
  children of the root, and so on.

For an incremental "reconstruct" the collection of files would not be
a single tree with a root, but a forest, and the roots to look for are
not manifests without parent, but with a parent which is already
present in the repository. After one such root has been found and
processed the unprocessed files have to be searched further for more
roots, and only if no such are found anymore will the remaining files
be considered as superfluous.

We can use the functions in "manifest.c" for the parsing and following
the parental chain.

Hm. But we have no direct child information. So the above algorithm
has to be modified, we have to scan all manifests before we start
importing, and we have to create a reverse index, from manifest to
children so that we can perform the import from root to leaves.

 *				(which may be " or {) up to but not including
 *				the space, semicolon, or bracket that
 *				terminates the word. NumComponents counts the
 *				total number of sub-tokens that make up the
 *				word. This includes, for example, sub-tokens
 *				of TCL_TOKEN_VARIABLE tokens.
 * TCL_TOKEN_SIMPLE_WORD -	This token is just like TCL_TOKEN_WORD except
 *				that the word is guaranteed to consist of a
 *				single TCL_TOKEN_TEXT sub-token.
 * TCL_TOKEN_TEXT -		The token describes a range of literal text
 *				that is part of a word. NumComponents is
 *				always 0.
 * TCL_TOKEN_BS -		The token describes a backslash sequence that
 *				must be collapsed. NumComponents is always 0.
 * TCL_TOKEN_COMMAND -		The token describes a command whose result
 *				must be substituted into the word. The token
 *				includes the enclosing brackets. NumComponents
 *				is always 0.
 * TCL_TOKEN_VARIABLE -		The token describes a variable substitution,
 *				including the dollar sign, variable name, and
 *				array index (if there is one) up through the
 *				right parentheses. NumComponents tells how
 *				many additional tokens follow to represent the
 *				variable name. The first token will be a
 *				TCL_TOKEN_TEXT token that describes the
 *				variable name. If the variable is an array
 *				reference then there will be one or more
 *				additional tokens, of type TCL_TOKEN_TEXT,
 *				TCL_TOKEN_BS, TCL_TOKEN_COMMAND, and
 *				TCL_TOKEN_VARIABLE, that describe the array
 *				index; numComponents counts the total number
 *				of nested tokens that make up the variable
 *				reference, including sub-tokens of
 *				TCL_TOKEN_VARIABLE tokens.
 * TCL_TOKEN_SUB_EXPR -		The token describes one subexpression of an
 *				expression, from the first non-blank character
 *				of the subexpression up to but not including
 *				the space, brace, or bracket that terminates
 *				the subexpression. NumComponents counts the
 *				total number of following subtokens that make
 *				up the subexpression; this includes all
 *				subtokens for any nested TCL_TOKEN_SUB_EXPR
 *				tokens. For example, a numeric value used as a
 *				primitive operand is described by a
 *				TCL_TOKEN_SUB_EXPR token followed by a
 *				TCL_TOKEN_TEXT token. A binary subexpression
 *				is described by a TCL_TOKEN_SUB_EXPR token
 *				followed by the TCL_TOKEN_OPERATOR token for
 *				the operator, then TCL_TOKEN_SUB_EXPR tokens
 *				for the left then the right operands.
 * TCL_TOKEN_OPERATOR -		The token describes one expression operator.
 *				An operator might be the name of a math
 *				function such as "abs". A TCL_TOKEN_OPERATOR
 *				token is always preceeded by one
 *				TCL_TOKEN_SUB_EXPR token for the operator's
 *				subexpression, and is followed by zero or more
 *				TCL_TOKEN_SUB_EXPR tokens for the operator's
 *				operands. NumComponents is always 0.
 * TCL_TOKEN_EXPAND_WORD -	This token is just like TCL_TOKEN_WORD except
 *				that it marks a word that began with the
 *				literal character prefix "{*}". This word is
 *				marked to be expanded - that is, broken into
 *				words after substitution is complete.

 *				reset to an initial state. If the source

 * TCL_ENCODING_STOPONERROR -	If set, then the converter will return

 *				sequence or a source character that has no
