+RELEASE 1.2.0.d20091224 - Thu, 24 Dec 2009 17:20:55 -08000
+
+ From Jim Randall:
+ - Fixed temp filename race condition on Windows with long cmd lines.
+
+ From David Cournapeau:
+ - Fixed tryRun when sconf directory is in a variant dir.
+ - Do not add -fPIC for ifort tool on non-posix platforms (darwin and
+ windows).
+ - Fix bug 2294 (spurious CheckCC failures).
+ - Fix scons bootstrap process on windows 64 (wrong wininst name)
+
+ From William Deegan:
+ - Final merge from vs_revamp branch to main
+
+ - Added definition and usage of HOST_OS, HOST_ARCH, TARGET_OS,
+ TARGET_ARCH, currently only defined/used by Visual Studio
+ Compilers. This will be rolled out to other platforms/tools
+ in the future.
+
+ - Add check for python >= 3.0.0 and exit gracefully.
+ For 1.3 python >= 1.5.2 and < 3.0.0 are supported
+
+ - Fix bug 1944 - Handle non-existent .i file in swig emitter, previously
+ it would crash with an IOError exception. Now it will try to make an
+ educated guess on the module name based on the filename.
+
+ From Lukas Erlinghagen:
+
+ - Have AddOption() remove variables from the list of
+ seen-but-unknown variables (which are reported later).
+
+ - An option name and aliases can now be specified as a tuple.
+
+ From Hartmut Goebel:
+
+ - Textfile builder.
+
+ From Jared Grubb:
+
+ - use "is/is not" in comparisons with None instead of "==" or "!=".
+
+ From Jim Hunziker:
+
+ - Avoid adding -gphobos to a command line multiple times
+ when initializing use of the DMD compiler.
+
+ From Jason Kenney:
+
+ - Sugguested HOST/TARGET OS/ARCH separation.
+
+ From Steven Knight:

+ From Greg Noel:
+
+ - Remove redundant __metaclass__ initializations in Environment.py.
+
+ - Correct the documentation of text returned by sconf.Result().
+
+ - Document that filenames with '.' as the first character are
+ ignored by Glob() by default (matching UNIX glob semantics).
+
+ - Fix SWIG testing infrastructure to work on Mac OS X.
+
+ - Restructure a test that occasionally hung so that the test would
+ detect when it was stuck and fail instead.

+
+ From Gary Oberbrunner:
+
+ - When reporting a target that SCons doesn't know how to make,
+ specify whether it's a File, Dir, etc.

+
+ - Add $SWIGDIRECTORSUFFIX and $SWIGVERSION construction variables.
+
+ From Rob Managan:
+
+ - Add -recorder flag to Latex commands and updated internals to
+ use the output to find files TeX creates. This allows the MiKTeX
+ installations to find the created files
+
+ - Notify user of Latex errors that would get buried in the
+ Latex output
+
+ - Remove LATEXSUFFIXES from environments that don't initialize Tex.
+
+ - Add support for the glosaaries package for glossaries and acronyms

+ not create the actions for bibtex, makeindex,... by creating them
+ and other environment settings in one routine called by all four
+ tex tools.
+
+ - Fix problem with filenames of sideeffects when the user changes
+ the name of the output file from the latex default
+
+ - Add scanning of files included in Latex by means of \lstinputlisting{}
+ Patch from Stefan Hepp.
+

+ $F77FILESUFFIXES, $F90FILESUFFIXES, $F95FILESUFFIXES and
+ $FORTRANFILESUFFIXES variables.
+
+ From Steven Knight:
+
+ - Make the -d, -e, -w and --no-print-directory options "Ignored for
+ compatibility." (We're not going to implement them.)
+
+ - Fix a serious inefficiency in how SCons checks for whether any source
+ files are missing when a Builder call creates many targets from many
+ input source files.
+
+ - In Java projects, make the target .class files depend only on the
+ specific source .java files where the individual classes are defined.
+
+ - Don't store duplicate source file entries in the .sconsign file so
+ we don't endlessly rebuild the target(s) for no reason.
+
+ - Add a Variables object as the first step towards deprecating the
+ Options object name. Similarly, add BoolVariable(), EnumVariable(),
+ ListVariable(), PackageVariable() and PathVariable() functions
+ as first steps towards replacing BoolOption(), EnumOption(),
+ ListOption(), PackageOption() and PathOption().
+
+ - Change the options= keyword argument to the Environment() function
+ to variables=, to avoid confusion with SCons command-line options.
+ Continue supporting the options= keyword for backwards compatibility.
+
+ - When $SWIGFLAGS contains the -python flag, expect the generated .py
+ file to be in the same (sub)directory as the target.
+
+ - When compiling C++ files, allow $CCFLAGS settings to show up on the
+ command line even when $CXXFLAGS has been redefined.
+
+ - Fix --interactive with -u/-U/-D when a VariantDir() is used.
+
+ From Anatoly Techtonik:
+

+
+ From Matthew Wesley:
+
+ - Add support for the GDC 'D' language compiler.

+
+ From Benoit Belley:
+
+ - Fix the --keep-going flag so it builds all possible targets even when

+
+ - Fix being able to use $PDB and $WINDWOWS_INSERT_MANIFEST together.
+
+ - Don't crash if un-installing the Intel C compiler leaves left-over,

+ - Reduce the default stack size for -j worker threads to 256 Kbytes.
+ Provide user control over this value by adding --stack-size and
+ --warn=stack-size options, and a SetOption('stack_size') function.
+
+ - Fix a crash on Linux systems when trying to use the Intel C compiler
+ and no /opt/intel_cc_* directories are found.
+
+ - Improve using Python functions as actions by incorporating into
+ a FunctionAction's signature:
+ - literal values referenced by the byte code.
+ - values of default arguments
+ - code of nested functions
+ - values of variables captured by closures
+ - names of referenced global variables and functions
+
+ - Fix the closing message when --clean and --keep-going are both
+ used and no errors occur.
+
+ - Add support for the Intel C compiler on Mac OS X.
+
+ - Speed up reading SConscript files by about 20% (for some
+ configurations) by: 1) optimizing the SCons.Util.is_*() and
+ SCons.Util.flatten() functions; 2) avoiding unnecessary os.stat()
+ calls by using a File's .suffix attribute directly instead of
+ stringifying it.
+
+ From Jérôme Berger:
+
+ - Have the D language scanner search for .di files as well as .d files.
+
+ - Add a find_include_names() method to the Scanner.Classic class to
+ abstract out how included names can be generated by subclasses.
+
+ - Allow the D language scanner to detect multiple modules imported by
+ a single statement.
+
+ From Konstantin Bozhikov:
+
+ - Support expansion of construction variables that contain or refer
+ to lists of other variables or Nodes within expansions like $CPPPATH.
+
+ - Change variable substitution (the env.subst() method) so that an
+ input sequence (list or tuple) is preserved as a list in the output.
+
+ From David Cournapeau:
+
+ - Add a CheckDeclaration() call to configure contexts.
+
+ - Improve the CheckTypeSize() code.
+

+
+ - Support the ability to subclass the new-style "str" class as input
+ to Builders.
+
+ - Improve the performance of our type-checking by using isinstance()
+ with new-style classes.
+
+ - Fix #include (and other $*PATH variables searches) of files with
+ absolute path names. Don't die if they don't exist (due to being
+ #ifdef'ed out or the like).
+
+ - Fix --interactive mode when Default(None) is used.
+
+ - Fix --debug=memoizer to work around a bug in base Python 2.2 metaclass
+ initialization (by just not allowing Memoization in Python versions
+ that have the bug).
+
+ - Have the "scons-time time" subcommand handle empty log files, and
+ log files that contain no results specified by the --which option.
+
+ - Fix the max Y of vertical bars drawn by "scons-time --fmt=gnuplot".
+
+ - On Mac OS X, account for the fact that the header file generated
+ from a C++ file will be named (e.g.) file.cpp.h, not file.hpp.
+
+ - Fix floating-point numbers confusing the Java parser about
+ generated .class file names in some configurations.
+
+ - Document (nearly) all the values you can now fetch with GetOption().
+
+ - Fix use of file names containing strings of multiple spaces when
+ using ActionFactory instances like the Copy() or Move() function.
+
+ - Fix a 0.97 regression when using a variable expansion (like
+ $OBJSUFFIX) in a source file name to a builder with attached source
+ builders that match suffix (like Program()+Object()).
+
+ - Have the Java parser recognize generics (surrounded by angle brackets)
+ so they don't interfere with identifying anonymous inner classes.
+
+ - Avoid an infinite loop when trying to use saved copies of the
+ env.Install() or env.InstallAs() after replacing the method
+ attributes.
+
+ - Improve the performance of setting construction variables.
+
+ - When cloning a construction environment, avoid over-writing an
+ attribute for an added method if the user explicitly replaced it.

+
+ - Fix being able to SetOption('warn', ...) in SConscript files.
+
+ - Add a warning about env.Copy() being deprecated.
+
+ - Add warnings about the --debug={dtree,stree,tree} options

+
+ From Leanid Nazdrynau:
+
+ - Have the Copy() action factory preserve file modes and times
+ when copying individual files.
+
+ From Jan Nijtmans:
+
+ - If $JARCHDIR isn't set explicitly, use the .java_classdir attribute
+ that was set when the Java() Builder built the .class files.
+
+ From Greg Noel:
+
+ - Document the Dir(), File() and Entry() methods of Dir and File Nodes.
+
+ - Add the parse_flags option when creating Environments
+
+ From Gary Oberbrunner:
+
+ - Make File(), Dir() and Entry() return a list of Nodes when passed
+ a list of names, instead of trying to make a string from the name
+ list and making a Node from that string.
+
+ - Fix the ability to build an Alias in --interactive mode.
+
+ - Fix the ability to hash the contents of actions for nested Python
+ functions on Python versions where the inability to pickle them
+ returns a TypeError (instead of the documented PicklingError).
+
+ From Jonas Olsson:
+
+ - Fix use of the Intel C compiler when the top compiler directory,

+
+ - Fix how Python Value Nodes are printed in --debug=explain output.

+
+ - Have the --interactive mode "build" command with no arguments
+ build the specified Default() targets.

+ versions where all() is a builtin function.
+
+ From Daniel Svensson:
+
+ - Code correction in SCons.Util.is_List().
+
+ From Ben Webb:
+
+ - Support the SWIG %module statement with following modifiers in

+
+RELEASE 0.97.0d20071212 - Wed, 12 Dec 2007 09:29:32 -0600
+
+ From Benoit Belley:
+
+ - Fix occasional spurious rebuilds and inefficiency when using
+ --implicit-cache and Builders that produce multiple targets.
+
+ - Allow SCons to not have to know about the builders of generated
+ files when BuildDir(duplicate=0) is used, potentially allowing some
+ SConscript files to be ignored for smaller builds.
+
+ From David Cournapeau:
+
+ - Add a CheckTypeSize() call to configure contexts.
+
+ From Ken Deeter:
+
+ - Make the "contents" of Alias Nodes a concatenation of the children's
+ content signatures (MD5 checksums), not a concatenation of the
+ children's contents, to avoid using large amounts of memory during
+ signature calculation.
+
+ From Malte Helmert:
+
+ - Fix a lot of typos in the man page and User's Guide.
+
+ From Geoffrey Irving:
+
+ - Speed up conversion of paths in .sconsign files to File or Dir Nodes.
+
+ From Steven Knight:
+
+ - Add an Options.UnknownOptions() method that returns any settings
+ (from the command line, or whatever dictionary was passed in)
+ that aren't known to the Options object.
+
+ - Add a Glob() function.
+
+ - When removing targets with the -c option, use the absolute path (to
+ avoid problems interpreting BuildDir() when the top-level directory
+ is the source directory).
+
+ - Fix problems with Install() and InstallAs() when called through a
+ clone (of a clone, ...) of a cloned construction environment.
+
+ - When executing a file containing Options() settings, add the file's
+ directory to sys.path (so modules can be imported from there) and
+ explicity set __name__ to the name of the file so the statement's
+ in the file can deduce the location if they need to.
+
+ - Fix an O(n^2) performance problem when adding sources to a target
+ through calls to a multi Builder (including Aliases).
+
+ - Redefine the $WINDOWSPROGMANIFESTSUFFIX and
+ $WINDOWSSHLIBMANIFESTSUFFIX variables so they pick up changes to
+ the underlying $SHLIBSUFFIX and $PROGSUFFIX variables.
+
+ - Add a GetBuildFailures() function that can be called from functions
+ registered with the Python atexit module to print summary information
+ about any failures encountered while building.
+
+ - Return a NodeList object, not a Python list, when a single_source
+ Builder like Object() is called with more than one file.
+
+ - When searching for implicit dependency files in the directories
+ in a $*PATH list, don't create Dir Nodes for directories that
+ don't actually exist on-disk.
+
+ - Add a Requires() function to allow the specification of order-only
+ prerequisites, which will be updated before specified "downstream"
+ targets but which don't actually cause the target to be rebuilt.
+
+ - Restore the FS.{Dir,File,Entry}.rel_path() method.
+
+ - Make the default behavior of {Source,Target}Signatures('timestamp')
+ be equivalent to 'timestamp-match', not 'timestamp-newer'.
+
+ - Fix use of CacheDir with Decider('timestamp-newer') by updating
+ the modification time when copying files from the cache.
+
+ - Fix random issues with parallel (-j) builds on Windows when Python
+ holds open file handles (especially for SCons temporary files,
+ or targets built by Python function actions) across process creation.
+
+ From Maxim Kartashev:
+
+ - Fix test scripts when run on Solaris.
+
+ From Gary Oberbrunner:
+

+RELEASE 0.97.0d20070918 - Tue, 18 Sep 2007 10:51:27 -0500
+
+ From Steven Knight:
+
+ - Fix the wix Tool module to handle null entries in $PATH variables.
+
+ - Move the documentation of Install() and InstallAs() from the list
+ of functions to the list of Builders (now that they're implemented
+ as such).
+
+ - Allow env.CacheDir() to be set per construction environment. The
+ global CacheDir() function now sets an overridable global default.
+
+ - Add an env.Decider() method and a Node.Decider() method that allow
+ flexible specification of an arbitrary function to decide if a given
+ dependency has changed since the last time a target was built.
+
+ - Don't execute Configure actions (while reading SConscript files)
+ when cleaning (-c) or getting help (-h or -H).
+
+ - Add to each target an implicit dependency on the external command(s)
+ used to build the target, as found by searching env['ENV']['PATH']
+ for the first argument on each executed command line.
+
+ - Add support for a $IMPLICIT_COMMAND_DEPENDENCIES construction
+ variabe that can be used to disable the automatic implicit
+ dependency on executed commands.
+
+ - Add an "ensure_suffix" keyword to Builder() definitions that, when
+ true, will add the configured suffix to the targets even if it looks
+ like they already have a different suffix.
+
+ - Add a Progress() function that allows for calling a function or string
+ (or list of strings) to display progress while walking the DAG.
+
+ - Allow ParseConfig(), MergeFlags() and ParseFlags() to handle output
+ from a *config command with quoted path names that contain spaces.
+
+ - Make the Return() function stop processing the SConscript file and
+ return immediately. Add a "stop=" keyword argument that can be set
+ to False to preserve the old behavior.
+
+ - Fix use of exitstatfunc on an Action.
+
+ - Introduce all man page function examples with "Example:" or "Examples:".
+
+ - When a file gets added to a directory, make sure the directory gets
+ re-scanned for the new implicit dependency.
+
+ - Fix handling a file that's specified multiple times in a target
+ list so that it doesn't cause dependent Nodes to "disappear" from
+ the dependency graph walk.
+
+ From Carsten Koch:
+
+ - Avoid race conditions with same-named files and directory creation
+ when pushing copies of files to CacheDir().
+
+ From Tzvetan Mikov:
+
+ - Handle $ in Java class names.
+
+ From Gary Oberbrunner:
+
+ - Add support for the Intel C compiler on Windows64.
+
+ - On SGI IRIX, have $SHCXX use $CXX by default (like other platforms).
+
+ From Sohail Somani:
+
+ - When Cloning a construction environment, set any variables before
+ applying tools (so the tool module can access the configured settings)
+ and re-set them after (so they end up matching what the user set).
+
+ From Matthias Troffaes:
+
+ - Make sure extra auxiliary files generated by some LaTeX packages
+ and not ending in .aux also get deleted by scons -c.
+
+ From Greg Ward:
+
+ - Add a $JAVABOOTCLASSPATH variable for directories to be passed to the
+ javac -bootclasspath option.
+
+ From Christoph Wiedemann:
+
+ - Add implicit dependencies on the commands used to build a target.
+
+

+
+ From Lars Albertsson:
+
+ - Don't error if a #include line happens to match a directory
+ somewhere on a path (like $CPPPATH, $FORTRANPATH, etc.).
+
+ From Mark Bertoglio:
+
+ - Fix listing multiple projects in Visual Studio 7.[01] solution files,
+ including generating individual project GUIDs instead of re-using
+ the solution GUID.
+
+ From Jean Brouwers:
+
+ - Add /opt/SUNWspro/bin to the default execution PATH on Solaris.
+
+ From Allan Erskine:
+
+ - Only expect the Microsoft IDL compiler to emit *_p.c and *_data.c
+ files if the /proxy and /dlldata switches are used (respectively).
+
+ From Steven Knight:
+
+ - Have --debug=explain report if a target is being rebuilt because
+ AlwaysBuild() is specified (instead of "unknown reasons").
+
+ - Support {Get,Set}Option('help') to make it easier for SConscript
+ files to tell if a help option (-h, --help, etc.) has been specified.
+
+ - Support {Get,Set}Option('random') so random-dependency interaction
+ with CacheDir() is controllable from SConscript files.
+
+ - Add a new AddOption() function to support user-defined command-
+ line flags (like --prefix=, --force, etc.).
+
+ - Push and retrieve built symlinks to/from a CacheDir() as actual
+ symlinks, not by copying the file contents.
+
+ - Fix how the Action module handles stringifying the shared library
+ generator in the Tool/mingw.py module.
+
+ - When generating a config.h file, print "#define HAVE_{FEATURE} 1"
+ instad of just "#define HAVE_{FEATURE}", for more compatibility
+ with Autoconf-style projects.
+
+ - Fix expansion of $TARGET, $TARGETS, $SOURCE and $SOURCES keywords in
+ Visual C/C++ PDB file names.
+
+ - Fix locating Visual C/C++ PDB files in build directories.
+
+ - Support an env.AddMethod() method and an AddMethod() global function
+ for adding a new method, respectively, to a construction environment
+ or an arbitrary object (such as a class).
+
+ - Fix the --debug=time option when the -j option is specified and all
+ files are up to date.
+
+ - Add a $SWIGOUTDIR variable to allow setting the swig -outdir option,
+ and use it to identify files created by the swig -java option.
+
+ - Add a $SWIGPATH variable that specifies the path to be searched
+ for included SWIG files, Also add related $SWIGINCPREFIX and
+ $SWIGINCSUFFIX variables that specify the prefix and suffix to
+ be be added to each $SWIGPATH directory when expanded on the SWIG
+ command line.
+
+ - More efficient copying of construction environments (mostly borrowed
+ from copy.deepcopy() in the standard Python library).
+
+ - When printing --tree=prune output, don't print [brackets] around
+ source files, only do so for built targets with children.
+
+ - Fix interpretation of Builder source arguments when the Builder has
+ a src_suffix *and* a source_builder and the argument has no suffix.
+
+ - Fix use of expansions like ${TARGET.dir} or ${SOURCE.dir} in the
+ following construction variables: $FORTRANMODDIR, $JARCHDIR,
+ $JARFLAGS, $LEXFLAGS, $SWIGFLAGS, $SWIGOUTDIR and $YACCFLAGS.
+
+ - Fix dependencies on Java files generated by SWIG so they can be
+ detected and built in one pass.
+
+ - Fix SWIG when used with a BuildDir().
+
+ From Leanid Nazdrynau:
+
+ - When applying Tool modules after a construction environment has
+ already been created, don't overwrite existing $CFILESUFFIX and
+ $CXXFILESUFFIX value.
+
+ - Support passing the Java() builder a list of explicit .java files
+ (not only a list of directories to be scanned for .java files).
+
+ - Support passing .java files to the Jar() and JavaH() builders, which
+ then use the builder underlying the Java() builder to turn them into
+ .class files. (That is, the Jar()-Java() chain of builders become
+ multi-step, like the Program()-Object()-CFile() builders.)
+
+ - Support passing SWIG .i files to the Java builders (Java(),
+ Jar(), JavaH()), to cause intermediate .java files to be created
+ automatically.
+
+ - Add $JAVACLASSPATH and $JAVASOURCEPATH variables, that get added to
+ the javac "-classpath" and "-sourcepath" options. (Note that SCons
+ does *not* currently search these paths for implicit dependencies.)
+
+ - Commonize initialization of Java-related builders.
+
+ From Jan Nijtmans:
+
+ - Find Java anonymous classes when the next token after the name is
+ an open parenthesis.

+ finished.
+
+ From Sohail Somani:

+
+ From Steven Knight:

+ directory as a file) occurs while deciding if a node is up-to-date.
+
+ - Fix "maximum recursion" / "unhashable type" errors in $CPPPATH

+ SConstruct directory) to sys.path (PYTHONPATH);
+ 2) automatically importing site_scons/site_init.py;
+ 3) automatically adding site_scons/site_tools to the toolpath.
+
+ From John Pye:
+
+ - Change ParseConfig() to preserve white space in arguments passed in
+ as a list.
+
+ From a smith:
+
+ - Fix adding explicitly-named Java inner class files (and any
+ other file names that may contain a '$') to Jar files.
+
+ From David Vitek:
+
+ - Add a NoCache() function to mark targets as unsuitable for propagating
+ to (or retrieving from) a CacheDir().
+
+ From Ben Webb:
+
+ - If the swig -noproxy option is used, it won't generate a .py file,
+ so don't emit it as a target that we expect to be built.
+
+
+
+RELEASE 0.96.94 - Sun, 07 Jan 2007 18:36:20 -0600
+
+ NOTE: This is a pre-release of 0.97 for testing purposes.
+
+ From Anonymous:
+
+ - Allow arbitrary white space after a SWIG %module declaration.
+
+ From Paul:
+
+ - When compiling resources under MinGW, make sure there's a space
+ between the --include-dir option and its argument.
+
+ From Jay Kint:
+
+ - Alleviate long command line issues on Windows by executing command
+ lines directly via os.spawnv() if the command line doesn't need
+ shell interpretation (has no pipes, redirection, etc.).
+
+ From Walter Franzini:
+
+ - Exclude additional Debian packaging files from the copyright check.
+
+ From Fawad Halim:
+
+ - Handle the conflict between the impending Python 2.6 'as' keyword
+ and our Tool/as.py module name.
+
+ From Steven Knight:
+
+ - Speed up the Node.FS.Dir.rel_path() method used to generate path names
+ that get put into the .sconsign* file(s).
+
+ - Optimize Node.FS.Base.get_suffix() by computing the suffix once, up
+ front, when we set the Node's name. (Duh...)
+
+ - Reduce the Memoizer's responsibilities to simply counting hits and
+ misses when the --debug=memoizer option is used, not to actually
+ handling the key calculation and memoization itself. This speeds
+ up some configurations significantly, and should cause no functional
+ differences.
+
+ - Add a new scons-time script with subcommands for generating
+ consistent timing output from SCons configurations, extracting
+ various information from those timings, and displaying them in
+ different formats.
+
+ - Reduce some unnecessary stat() calls from on-disk entry type checks.
+
+ - Fix SideEffect() when used with -j, which was badly broken in 0.96.93.
+
+ - Propagate TypeError exceptions when evaluating construction variable
+ expansions up the stack, so users can see what's going on.
+
+ - When disambiguating a Node.FS.Entry into a Dir or File, don't look
+ in the on-disk source directory until we've confirmed there's no
+ on-disk entry locally and there *is* one in the srcdir. This avoids
+ creating a phantom Node that can interfere with dependencies on
+ directory contents.
+
+ - Add an AllowSubstExceptions() function that gives the SConscript
+ files control over what exceptions cause a string to expand to ''
+ vs. terminating processing with an error.
+
+ - Allow the f90.py and f95.py Tool modules to compile earlier source
+ source files of earlier Fortran version.
+
+ - Fix storing signatures of files retrieved from CacheDir() so they're
+ correctly identified as up-to-date next invocation.
+
+ - Make sure lists of computed source suffixes cached by Builder objects
+ don't persist across changes to the list of source Builders (so the
+ addition of suffixes like .ui by the qt.py Tool module take effect).
+
+ - Enhance the bootstrap.py script to allow it to be used to execute
+ SCons more easily from a checked-out source tree.
+
+ From Ben Leslie:
+
+ - Fix post-Memoizer value caching misspellings in Node.FS._doLookup().
+
+ From Rob Managan, Dmitry Mikhin and Joel B. Mohler:
+
+ - Handle TeX/LaTeX files in subdirectories by changing directory
+ before invoking TeX/LaTeX.
+
+ - Scan LaTeX files for \bibliography lines.
+
+ - Support multiple file names in a "\bibliography{file1,file2}" string.
+
+ - Handle TeX warnings about undefined citations.
+
+ - Support re-running LaTeX if necessary due to a Table of Contents.
+
+ From Dmitry Mikhin:
+
+ - Return LaTeX if "Rerun to get citations correct" shows up on the next
+ line after the "Warning:" string.
+
+ From Gary Oberbrunner:
+
+ - Add #include lines to fix portability issues in two tests.
+
+ - Eliminate some unnecessary os.path.normpath() calls.
+
+ - Add a $CFLAGS variable for C-specific options, leaving $CCFLAGS
+ for options common to C and C++.
+
+ From Tom Parker:
+
+ - Have the error message print the missing file that Qt can't find.
+
+ From John Pye:
+
+ - Fix env.MergeFlags() appending to construction variable value of None.
+
+ From Steve Robbins:
+
+ - Fix the "sconsign" script when the .sconsign.dblite file is explicitly
+ specified on the command line (and not intuited from the old way of
+ calling it with just ".sconsign").
+
+ From Jose Pablo Ezequiel "Pupeno" Fernandez Silva:
+
+ - Give the 'lex' tool knowledge of the additional target files produced
+ by the flex "--header-file=" and "--tables-file=" options.
+
+ - Give the 'yacc' tool knowledge of the additional target files produced
+ by the bison "-g", "--defines=" and "--graph=" options.
+
+ - Generate intermediate files with Objective C file suffixes (.m) when
+ the lex and yacc source files have appropriate suffixes (.lm and .ym).
+
+ From Sohail Somain:
+
+ - Have the mslink.py Tool only look for a 'link' executable on Windows
+ systems.
+
+ From Vaclav Smilauer:
+
+ - Add support for a "srcdir" keyword argument when calling a Builder,
+ which will add a srcdir prefix to all non-relative string sources.
+
+ From Jonathan Ultis:
+
+ - Allow Options converters to take the construction environment as
+ an optional argument.
+
+
+
+RELEASE 0.96.93 - Mon, 06 Nov 2006 00:44:11 -0600
+
+ NOTE: This is a pre-release of 0.97 for testing purposes.
+
+ From Anonymous:
+
+ - Allow Python Value Nodes to be Builder targets.
+
+ From Matthias:
+
+ - Only filter Visual Studio common filename prefixes on complete
+ directory names.
+
+ From Chad Austin:
+
+ - Fix the build of the SCons documentation on systems that don't
+ have "python" in the $PATH.
+
+ From Ken Boortz:
+
+ - Enhance ParseConfig() to recognize options that begin with '+'.
+
+ From John Calcote, Elliot Murphy:
+
+ - Document ways to override the CCPDBFLAGS variable to use the
+ Microsoft linker's /Zi option instead of the default /Z7.
+
+ From Christopher Drexler:
+
+ - Make SCons aware bibtex must be called if any \include files
+ cause creation of a bibliography.
+
+ - Make SCons aware that "\bilbiography" in TeX source files means
+ that related .bbl and .blg bibliography files will be created.
+ (NOTE: This still needs to search for the string in \include files.)
+
+ From David Gruener:
+
+ - Fix inconsistent handling of Action strfunction arguments.
+
+ - Preserve white space in display Action strfunction strings.
+
+ From James Y. Knight and Gerard Patel:
+
+ - Support creation of shared object files from assembly language.
+
+ From Steven Knight:
+
+ - Speed up the Taskmaster significantly by avoiding unnecessary
+ re-scans of Nodes to find out if there's work to be done, having it
+ track the currently-executed top-level target directly and not
+ through its presence on the target list, and eliminating some other
+ minor list(s), method(s) and manipulation.
+
+ - Fix the expansion of $TARGET and $SOURCE in the expansion of
+ $INSTALLSTR displayed for non-environment calls to InstallAs().
+
+ - Fix the ability to have an Alias() call refer to a directory
+ name that's not identified as a directory until later.
+
+ - Enhance runtest.py with an option to use QMTest as the harness.
+ This will become the default behavior as we add more functionality
+ to the QMTest side.
+
+ - Let linking on mingw use the default function that chooses $CC (gcc)
+ or $CXX (g++) depending on whether there are any C++ source files.
+
+ - Work around a bug in early versions of the Python 2.4 profile module
+ that caused the --profile= option to fail.
+
+ - Only call Options validators and converters once when initializing a
+ construction environment.
+
+ - Fix the ability of env.Append() and env.Prepend(), in all known Python
+ versions, to handle different input value types when the construction
+ variable being updated is a dictionary.
+
+ - Add a --cache-debug option for information about what files it's
+ looking for in a CacheDir().
+
+ - Document the difference in construction variable expansion between
+ {Action,Builder}() and env.{Action,Builder}().
+
+ - Change the name of env.Copy() to env.Clone(), keeping the old name
+ around for backwards compatibility (with the intention of eventually
+ phasing it out to avoid confusion with the Copy() Action factory).
+
+ From Arve Knudsen:
+
+ - Support cleaning and scanning SWIG-generated files.
+
+ From Carsten Koch:
+
+ - Allow selection of Visual Studio version by setting $MSVS_VERSION
+ after construction environment initialization.
+
+ From Jean-Baptiste Lab:
+
+ - Try using zipimport if we can't import Tool or Platform modules
+ using the normal "imp" module. This allows SCons to be packaged
+ using py2exe's all-in-one-zip-file approach.
+
+ From Ben Liblit:
+
+ - Do not re-scan files if the scanner returns no implicit dependencies.
+
+ From Sanjoy Mahajan:
+
+ - Change use of $SOURCES to $SOURCE in all TeX-related Tool modules.
+
+ From Joel B. Mohler:
+
+ - Make SCons aware that "\makeindex" in TeX source files means that
+ related .ilg, .ind and .idx index files will be created.
+ (NOTE: This still needs to search for the string in \include files.)
+
+ - Prevent scanning the TeX .aux file for additional files from
+ trying to remove it twice when the -c option is used.
+
+ From Leanid Nazdrynau:
+
+ - Give the MSVC RES (resource) Builder a src_builder list and a .rc
+ src_suffix so other builders can generate .rc files.
+
+ From Matthew A. Nicholson:
+
+ - Enhance Install() and InstallAs() to handle directory trees as sources.
+
+ From Jan Nijtmans:
+
+ - Don't use the -fPIC flag when using gcc on Windows (e.g. MinGW).
+
+ From Greg Noel:
+
+ - Add an env.ParseFlags() method that provides separate logic for
+ parsing GNU tool chain flags into a dictionary.
+
+ - Add an env.MergeFlags() method to apply an arbitrary dictionary
+ of flags to a construction environment's variables.
+
+ From Gary Oberbrunner:
+
+ - Fix parsing tripartite Intel C compiler version numbers on Linux.
+
+ - Extend the ParseConfig() function to recognize -arch and
+ -isysroot options.
+
+ - Have the error message list the known suffixes when a Builder call
+ can't build a source file with an unknown suffix.
+
+ From Karol Pietrzak:
+
+ - Avoid recursive calls to main() in the program snippet used by the
+ SConf subsystem to test linking against libraries. This changes the
+ default behavior of CheckLib() and CheckLibWithHeader() to print
+ "Checking for C library foo..." instead of "Checking for main()
+ in C library foo...".
+
+ From John Pye:
+
+ - Throw an exception if a command called by ParseConfig() or
+ ParseFlags() returns an error.
+
+ From Stefan Seefeld:
+
+ - Initial infrastructure for running SCons tests under QMTest.
+
+ From Sohail Somani:
+
+ - Fix tests that fail due to gcc warnings.
+
+ From Dobes Vandermeer:
+
+ - In stack traces, print the full paths of SConscript files.
+
+ From Atul Varma:
+
+ - Fix detection of Visual C++ Express Edition.
+
+ From Dobes Vandermeer:
+
+ - Let the src_dir option to the SConscript() function affect all the
+ the source file paths, instead of treating all source files paths
+ as relative to the SConscript directory itself.
+
+ From Nicolas Vigier:
+
+ - Fix finding Fortran modules in build directories.
+
+ - Fix use of BuildDir() when the source file in the source directory
+ is a symlink with a relative path.
+
+ From Edward Wang:
+
+ - Fix the Memoizer when the SCons Python modules are executed from
+ .pyo files at different locations from where they were compiled.
+
+ From Johan Zander:
+
+ - Fix missing os.path.join() when constructing the $FRAMEWORKSDKDIR/bin.
+
+
+
+RELEASE 0.96.92 - Mon, 10 Apr 2006 21:08:22 -0400

+
+ From Matthias:
+
+ - Support generating project and solution files for Microsoft
+ Visual Studio version 8.
+
+ - Support generating more than one project file for a Microsoft

+
+ - Add support for a support "runfile" parameter to Microsoft
+ Visual Studio project file creation.
+
+ - Put the project GUID, not the solution GUID, in the right spot
+ in the solution file.
+
+ From Erling Andersen:
+
+ - Fix interpretation of Node.FS objects wrapped in Proxy instances,
+ allowing expansion of things like ${File(TARGET)} in command lines.
+
+ From Stanislav Baranov:
+
+ - Add a separate MSVSSolution() Builder, with support for the
+ following new construction variables: $MSVSBUILDCOM, $MSVSCLEANCOM,
+ $MSVSENCODING, $MSVSREBUILDCOM, $MSVSSCONS, $MSVSSCONSCOM,
+ $MSVSSCONSFLAGS, $MSVSSCONSCRIPT and $MSVSSOLUTIONCOM.
+
+ From Ralph W. Grosse-Kunstleve and Patrick Mezard:
+
+ - Remove unneceesary (and incorrect) SCons.Util strings on some function
+ calls in SCons.Util.
+
+ From Bob Halley:
+
+ - Fix C/C++ compiler selection on AIX to not always use the external $CC
+ environment variable.
+
+ From August Hörandl:
+
+ - Add a scanner for \include and \import files, with support for
+ searching a directory list in $TEXINPUTS (imported from the external
+ environment).
+
+ - Support $MAKEINDEX, $MAKEINDEXCOM, $MAKEINDEXCOMSTR and
+ $MAKEINDEXFLAGS for generating indices from .idx files.
+
+ From Steven Johnson:
+
+ - Add a NoClean() Environment method and function to override removal
+ of targets during a -c clean, including documentation and tests.
+
+ From Steven Knight:
+
+ - Check for whether files exist on disk by listing the directory
+ contents, not calling os.path.exists() file by file. This is
+ somewhat more efficient in general, and may be significantly
+ more efficient on Windows.
+
+ - Minor speedups in the internal is_Dict(), is_List() and is_String()
+ functions.
+
+ - Fix a signature refactoring bug that caused Qt header files to
+ get re-generated every time.
+
+ - Don't fail when writing signatures if the .sconsign.dblite file is
+ owned by a different user (e.g. root) from a previous run.
+
+ - When deleting variables from stacked OverrideEnvironments, don't
+ throw a KeyError if we were able to delte the variable from any
+ Environment in the stack.
+
+ - Get rid of the last indentation tabs in the SCons source files and
+ add -tt to the Python invocations in the packaging build and the
+ tests so they don't creep back in.
+
+ - In Visual Studio project files, put quotes around the -C directory
+ so everything works even if the path has spaces in it.
+
+ - The Intel Fortran compiler uses -object:$TARGET, not "-o $TARGET",
+ when building object files on Windows. Have the the ifort Tool
+ modify the default command lines appropriately.
+
+ - Document the --debug=explain option in the man page. (How did we
+ miss this?)
+
+ - Add a $LATEXRETRIES variable to allow configuration of the number of
+ times LaTex can be re-called to try to resolve undefined references.
+
+ - Change the order of the arguments to Configure.Checklib() to match
+ the documentation.
+
+ - Handle signature calculation properly when the Python function used
+ for a FunctionAction is an object method.
+
+ - On Windows, assume that absolute path names without a drive letter
+ refer to the drive on which the SConstruct file lives.
+
+ - Add /usr/ccs/bin to the end of the the default external execution
+ PATH on Solaris.
+
+ - Add $PKGCHK and $PKGINFO variables for use on Solaris when searching
+ for the SunPRO C++ compiler. Make the default value for $PKGCHK
+ be /usr/sbin/pgkchk (since /usr/sbin isn't usually on the external
+ execution $PATH).
+
+ - Fix a man page example of overriding variables when calling
+ SharedLibrary() to also set the $LIBSUFFIXES variable.
+
+ - Add a --taskmastertrace=FILE option to give some insight on how
+ the taskmaster decides what Node to build next.
+
+ - Changed the names of the old $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
+ $WIN32DLLPREFIX and $WIN32IMPLIBPREFIX construction variables to
+ new $WINDOWSDEFPREFIX, $WINDOWSDEFSUFFIX, $WINDOWSDLLPREFIX and
+ $WINDOWSIMPLIBPREFIX construction variables. The old names are now
+ deprecated, but preserved for backwards compatibility.
+
+ - Fix (?) a runtest.py hang on Windows when the --xml option is used.
+
+ - Change the message when an error occurs trying to interact with the
+ file system to report the target(s) in square brackets (as before) and
+ the actual file or directory that encountered the error afterwards.
+
+ From Chen Lee:
+
+ - Add x64 support for Microsoft Visual Studio 8.
+
+ From Baptiste Lepilleur:
+
+ - Support the --debug=memory option on Windows when the Python version
+ has the win32process and win32api modules.
+
+ - Add support for Visual Studio 2005 Pro.
+
+ - Fix portability issues in various tests: test/Case.py,
+ Test/Java/{JAR,JARCHDIR,JARFLAGS,JAVAC,JAVACFLAGS,JAVAH,RMIC}.py,
+ test/MSVS/vs-{6.0,7.0,7.1,8.0}-exec.py,
+ test/Repository/{Java,JavaH,RMIC}.py,
+ test/QT/{generated-ui,installed,up-to-date,warnings}.py,
+ test/ZIP/ZIP.py.
+
+ - Ignore pkgchk errors on Solaris when searching for the C++ compiler.
+
+ - Speed up the SCons/EnvironmentTests.py unit tests.
+
+ - Add a --verbose= option to runtest.py to print executed commands
+ and their output at various levels.

+ - Add support for Visual Studio Express Editions.
+
+ - Add support for Visual Studio 8 *.manifest files, includng
+ new $WINDOWS_INSERT_MANIFEST, $WINDOWSPROGMANIFESTSUFFIX,

+ "new" keyword inside an inner class.
+
+ From Sanjoy Mahajan:
+
+ - Correct TeX-related command lines to just $SOURCE, not $SOURCES
+
+ From Patrick Mezard:
+
+ - Execute build commands for a command-line target if any of the

+ not just if the command-line target itself is out of date.
+
+ - Fix the -n option when used with -c to print all of the targets
+ that will be removed for a multi-target Builder call.
+
+ - If there's no file in the source directory, make sure there isn't
+ one in the build directory, too, to avoid dangling files left
+ over from previous runs when a source file is removed.
+
+ - Allow AppendUnique() and PrependUnique() to append strings (and
+ other atomic objects) to lists.
+
+ From Joel B. Mohler:
+
+ - Extend latex.py, pdflatex.py, pdftex.py and tex.py so that building
+ from both TeX and LaTeX files uses the same logic to call $BIBTEX
+ when it's necessary, to call $MAKEINDEX when it's necessary, and to
+ call $TEX or $LATEX multiple times to handle undefined references.
+
+ - Add an emitter to the various TeX builders so that the generated
+ .aux and .log files also get deleted by the -c option.
+
+ From Leanid Nazdrynau:
+
+ - Fix the Qt UIC scanner to work with generated .ui files (by using
+ the FindFile() function instead of checking by-hand for the file).
+
+ From Jan Nieuwenhuizen:

+
+ From Greg Noel:
+
+ - Add /sw/bin to the default execution PATH on Mac OS X.

+
+ - Recognize the Java 1.5 enum keyword.
+
+ From Asfand Yar Qazi:
+
+ - Add /opt/bin to the default execution PATH on all POSIX platforms
+ (between /usr/local/bin and /bin).
+
+ From Jon Rafkind:

+ SConscript files.
+
+ From Christoph Schulz:
+
+ - Add support for $CONFIGUREDIR and $CONFIGURELOG variables to control
+ the directory and logs for configuration tests.
+
+ - Add support for a $INSTALLSTR variable.
+
+ - Add support for $RANLIBCOM and $RANLIBCOMSTR variables (which fixes

+
+ From Amir Szekely:
+
+ - Add use of $CPPDEFINES to $RCCOM (resource file compilation) on MinGW.
+
+ From Erick Tryzelaar:
+
+ - Fix the error message when trying to report that a given option is
+ not gettable/settable from an SConscript file.
+
+ From Dobes Vandermeer:
+
+ - Add support for SCC and other settings in Microsoft Visual

+ $MSVS_PROJECT_GUID, $MSVS_SCC_AUX_PATH, $MSVS_SCC_LOCAL_PATH,
+ $MSVS_SCC_PROJECT_NAME, $MSVS_SCC_PROVIDER,
+
+ - Add support for using a $SCONS_HOME variable (imported from the
+ external environment, or settable internally) to put a shortened
+ SCons execution line in the Visual Studio project file.
+

+
+ - Only filter common prefixes from source files names in Visual Studio
+ project files if the prefix is a complete (sub)directory name.
+
+ From Thad Ward:
+
+ - If $MSVSVERSIONS is already set, don't overwrite it with
+ information from the registry.

+
+RELEASE 0.96.91 - Thu, 08 Sep 2005 07:18:23 -0400
+
+ NOTE: This was a pre-release of 0.97 for testing purposes.
+
+ From Chad Austin:
+
+ - Have the environment store the toolpath and re-use it to find Tools
+ modules during later Copy() or Tool() calls (unless overridden).
+
+ - Normalize the directory path names in SConsignFile() database
+ files so the same signature file can interoperate on Windows and
+ non-Windows systems.
+
+ - Make --debug=stacktrace print a stacktrace when a UserError is thrown.
+
+ - Remove an old, erroneous cut-and-paste comment in Scanner/Dir.py.
+
+ From Stanislav Baranov:
+
+ - Make it possible to support with custom Alias (sub-)classes.
+
+ - Allow Builders to take empty source lists when called.
+
+ - Allow access to both TARGET and SOURCE in $*PATH expansions.
+
+ - Allow SConscript files to modify BUILD_TARGETS.
+
+ From Timothee Besset:
+
+ - Add support for Objective C/C++ .m and .mm file suffixes (for
+ Mac OS X).
+
+ From Charles Crain
+
+ - Fix the PharLap linkloc.py module to use target+source arguments
+ when calling env.subst().
+
+ From Bjorn Eriksson:
+
+ - Fix an incorrect Command() keyword argument in the man page.
+
+ - Add a $TEMPFILEPREFIX variable to control the prefix or flag used
+ to pass a long-command-line-execution tempfile to a command.
+
+ From Steven Knight:
+
+ - Enhanced the SCons setup.py script to install man pages on
+ UNIX/Linux systems.
+
+ - Add support for an Options.FormatOptionHelpText() method that can
+ be overridden to customize the format of Options help text.
+
+ - Add a global name for the Entry class (which had already been
+ documented).
+
+ - Fix re-scanning of generated source files for implicit dependencies
+ when the -j option is used.
+
+ - Fix a dependency problem that caused $LIBS scans to not be added
+ to all of the targets in a multiple-target builder call, which
+ could cause out-of-order builds when the -j option is used.
+
+ - Store the paths of source files and dependencies in the .sconsign*
+ file(s) relative to the target's directory, not relative to the
+ top-level SConstruct directory. This starts to make it possible to
+ subdivide the dependency tree arbitrarily by putting an SConstruct
+ file in every directory and using content signatures.
+
+ - Add support for $YACCHFILESUFFIX and $YACCHXXFILESUFFIX variables
+ that accomodate parser generators that write header files to a
+ different suffix than the hard-coded .hpp when the -d option is used.
+
+ - The default behavior is now to store signature information in a
+ single .sconsign.dblite file in the top-level SConstruct directory.
+ The old behavior of a separate .sconsign file in each directory can
+ be specified by calling SConsignFile(None).
+
+ - Remove line number byte codes within the signature calculation
+ of Python function actions, so that changing the location of an
+ otherwise unmodified Python function doesn't cause rebuilds.
+
+ - Fix AddPreAction() and AddPostAction() when an action has more than
+ one target file: attach the actions to the Executor, not the Node.
+
+ - Allow the source directory of a BuildDir / build_dir to be outside
+ of the top-level SConstruct directory tree.
+
+ - Add a --debug=nomemoizer option that disables the Memoizer for clearer
+ looks at the counts and profiles of the underlying function calls,
+ not the Memoizer wrappers.
+
+ - Print various --debug= stats even if we exit early (e.g. using -h).
+
+ - Really only use the cached content signature value if the file
+ is older than --max-drift, not just if --max-drift is set.
+
+ - Remove support for conversion from old (pre 0.96) .sconsign formats.
+
+ - Add support for a --diskcheck option to enable or disable various
+ on-disk checks: that File and Dir nodes match on-disk entries;
+ whether an RCS file exists for a missing source file; whether an
+ SCCS file exists for a missing source file.
+
+ - Add a --raw argument to the sconsign script, so it can print a
+ raw representation of each entry's NodeInfo dictionary.
+
+ - Add the 'f90' and 'f95' tools to the list of Fortran compilers
+ searched for by default.
+
+ - Add the +Z option by default when compiling shared objects on
+ HP-UX.
+
+ From Chen Lee:
+
+ - Handle Visual Studio project and solution files in Unicode.
+
+ From Sanjoy Mahajan:
+
+ - Fix a bad use of Copy() in an example in the man page, and a
+ bad regular expression example in the man page and User's Guide.
+
+ From Shannon Mann:
+
+ - Have the Visual Studio project file(s) echo "Starting SCons" before
+ executing SCons, mainly to work around a quote-stripping bug in
+ (some versions of?) the Windows cmd command executor.
+
+ From Georg Mischler:
+
+ - Remove the space after the -o option when invoking the Borland
+ BCC compiler; some versions apparently require that the file name
+ argument be concatenated with the option.
+
+ From Leanid Nazdrynau:
+
+ - Fix the Java parser's handling of backslashes in strings.
+
+ From Greg Noel:
+
+ - Add construction variables to support frameworks on Mac OS X:
+ $FRAMEWORKS, $FRAMEWORKPREFIX, $FRAMEWORKPATH, $FRAMEWORKPATHPREFIX.
+
+ - Re-order link lines so the -o option always comes right after the
+ command name.
+
+ From Gary Oberbrunner:
+
+ - Add support for Intel C++ beta 9.0 (both 32 and 64 bit versions).
+
+ - Document the new $FRAMEWORK* variables for Mac OS X.
+
+ From Karol Pietrzak:
+
+ - Add $RPATH (-R) support to the Sun linker Tool (sunlink).
+
+ - Add a description of env.subst() to the man page.
+
+ From Chris Prince:
+
+ - Look in the right directory, not always the local directory, for a
+ same-named file or directory conflict on disk.
+
+ - On Windows, preserve the external environment's %SYSTEMDRIVE%
+ variable, too.
+
+ From Craig Scott:
+
+ - Have the Fortran module emitter look for Fortan modules to be created
+ relative to $FORTRANMODDIR, not the top-level directory.
+
+ - When saving Options to a file, run default values through the
+ converter before comparing them with the set values. This correctly
+ suppresses Boolean Option values from getting written to the saved
+ file when they're one of the many synonyms for a default True or
+ False value.
+
+ - Fix the Fortran Scanner's ability to handle a module being used
+ in the same file in which it is defined.
+
+ From Steve-o:
+
+ - Add the -KPIC option by default when compiling shared objects on
+ Solaris.
+
+ - Change the default suffix for Solaris objects to .o, to conform to
+ Sun WorkShop's expectations. Change the profix to so_ so they can
+ still be differentiated from static objects in the same directory.
+
+ From Amir Szekely:
+
+ - When calling the resource compiler on MinGW, add --include-dir and
+ the source directory so it finds the source file.
+
+ - Update EnsureSConsVersion() to support revision numbers.
+
+ From Greg Ward:
+
+ - Fix a misplaced line in the man page.
+
+
+
+RELEASE 0.96.90 - Tue, 15 Feb 2005 21:21:12 +0000
+
+ NOTE: This was a pre-release of 0.97 for testing purposes.
+
+ From Anonymous:
+
+ - Fix Java parsing to avoid erroneously identifying a new array
+ of class instances as an anonymous inner class.
+
+ - Fix a typo in the man page description of PathIsDirCreate.
+
+ From Chad Austin:
+
+ - Allow Help() to be called multiple times, appending to the help
+ text each call.
+
+ - Allow Tools found on a toolpath to import Python modules from
+ their local directory.
+
+ From Steve Christensen:
+
+ - Handle exceptions from Python functions as build actions.
+
+ - Add a set of canned PathOption validators: PathExists (the default),
+ PathIsFile, PathIsDir and PathIsDirCreate.
+
+ From Matthew Doar:
+
+ - Add support for .lex and .yacc file suffixes for Lex and Yacc files.
+
+ From Eric Frias:
+
+ - Huge performance improvement: wrap the tuples representing an
+ include path in an object, so that the time it takes to hash the
+ path doesn't grow porportionally to the length of the path.
+
+ From Gottfried Ganssauge:
+
+ - Fix SCons on SuSE/AMD-64 Linux by having the wrapper script also
+ check for the build engine in the parent directory of the Python
+ library directory (/usr/lib64 instead of /usr/lib).
+
+ From Stephen Kennedy:
+
+ - Speed up writing the .sconsign file at the end of a run by only
+ calling sync() once at the end, not after every entry.
+
+ From Steven Knight:
+
+ - When compiling with Microsoft Visual Studio, don't include the ATL and
+ MFC directories in the default INCLUDE and LIB environment variables.
+
+ - Remove the following deprecated features: the ParseConfig()
+ global function (deprecated in 0.93); the misspelled "validater"
+ keyword to the Options.Add() method (deprecated in 0.91); the
+ SetBuildSignatureType(), SetContentSignatureType(), SetJobs() and
+ GetJobs() global functions (deprecated in 0.14).
+
+ - Fix problems with corrupting the .sconsign.dblite file when
+ interrupting builds by writing to a temporary file and renaming,
+ not writing the file directly.
+
+ - Fix a 0.96 regression where when running with -k, targets built from
+ walking dependencies later on the command line would not realize
+ that a dependency had failed an earlier build attempt, and would
+ try to rebuild the dependent targets.
+
+ - Change the final messages when using -k and errors occur from
+ "{building,cleaning} terminated because of errors" to "done
+ {building,cleaning} targets (errors occurred during {build,clean})."
+
+ - Allow Configure.CheckFunc() to take an optional header argument
+ (already supported by Conftest.py) to specify text at the top of
+ the compiled test file.
+
+ - Fix the --debug=explain output when a Python function action changed
+ so it prints a meaningful string, not the binary representation of
+ the function contents.
+
+ - Allow a ListOption's default value(s) to be a Python list of specified
+ values, not just a string containing a comma-separated list of names.
+
+ - Add a ParseDepends() function that will parse up a list of explicit
+ dependencies from a "make depend" style file.
+
+ - Support the ability to change directory when executing an Action
+ through "chdir" keyword arguments to Action and Builder creation
+ and calls.
+
+ - Fix handling of Action ojects (and other callables that don't match
+ our calling arguments) in construction variable expansions.
+
+ - On Win32, install scons.bat in the Python directory when installing
+ from setup.py. (The bdist_wininst installer was already doing this.)
+
+ - Fix env.SConscript() when called with a list of SConscipt files.
+ (The SConscript() global function already worked properly.)
+
+ - Add a missing newline to the end of the --debug=explain "unknown
+ reasons" message.
+
+ - Enhance ParseConfig() to work properly for spaces in between the -I,
+ -L and -l options and their arguments.
+
+ - Packaging build fix: Rebuild the files that are use to report the
+ --version of SCons whenever the development version number changes.
+
+ - Fix the ability to specify a target_factory of Dir() to a Builder,
+ which the default create-a-directory Builder was interfering with.
+
+ - Mark a directory as built if it's created as part of the preparation
+ for another target, to avoid trying to build it again when it comes
+ up in the target list.
+
+ - Allow a function with the right calling signature to be put directly
+ in an Environment's BUILDERS dictionary, making for easier creation
+ and use of wrappers (pseudo-Builders) that call other Builders.
+
+ - On Python 2.x, wrap lists of Nodes returned by Builders in a UserList
+ object that adds a method that makes str() object return a string
+ with all of the Nodes expanded to their path names. (Builders under
+ Python 1.5.2 still return lists to avoid TypeErrors when trying
+ to extend() list, so Python 1.5.2 doesn't get pretty-printing of Node
+ lists, but everything should still function.)
+
+ - Allow Aliases to have actions that will be executed whenever
+ any of the expanded Alias targets are out of date.
+
+ - Fix expansion of env.Command() overrides within target and
+ source file names.
+
+ - Support easier customization of what's displayed by various default
+ actions by adding lots of new construction variables: $ARCOMSTR,
+ $ASCOMSTR, $ASPPCOMSTR, $BIBTEXCOMSTR, $BITKEEPERCOMSTR, $CCCOMSTR,
+ $CVSCOMSTR, $CXXCOMSTR, $DCOMSTR, $DVIPDFCOMSTR, $F77COMSTR,
+ $F90COMSTR, $F95COMSTR, $FORTRANCOMSTR, $GSCOMSTR, $JARCOMSTR,
+ $JAVACCOMSTR, $JAVAHCOMSTR, $LATEXCOMSTR, $LEXCOMSTR, $LINKCOMSTR,
+ $M4COMSTR, $MIDLCOMSTR, $P4COMSTR, $PCHCOMSTR, $PDFLATEXCOMSTR,
+ $PDFTEXCOMSTR, $PSCOMSTR, $QT_MOCFROMCXXCOMSTR, $QT_MOCFROMHCOMSTR,
+ $QT_UICCOMSTR, $RCCOMSTR, $REGSVRCOMSTR, $RCS_COCOMSTR, $RMICCOMSTR,
+ $SCCSCOMSTR, $SHCCCOMSTR, $SHCXXCOMSTR, $SHF77COMSTR, $SHF90COMSTR,
+ $SHF95COMSTR, $SHFORTRANCOMSTR, $SHLINKCOMSTR, $SWIGCOMSTR,
+ $TARCOMSTR, $TEXCOMSTR, $YACCCOMSTR and $ZIPCOMSTR.
+
+ - Add an optional "map" keyword argument to ListOption() that takes a
+ dictionary to map user-specified values to legal values from the list
+ (like EnumOption() already doee).
+
+ - Add specific exceptions to try:-except: blocks without any listed,
+ so that they won't catch and mask keyboard interrupts.
+
+ - Make --debug={tree,dtree,stree} print something even when there's
+ a build failure.
+
+ - Fix how Scanners sort the found dependencies so that it doesn't
+ matter whether the dependency file is in a Repository or not.
+ This may cause recompilations upon upgrade to this version.
+
+ - Make AlwaysBuild() work with Alias and Python value Nodes (making
+ it much simpler to support aliases like "clean" that just invoke
+ an arbitrary action).
+
+ - Have env.ParseConfig() use AppendUnique() by default to suppress
+ duplicate entries from multiple calls. Add a "unique" keyword
+ argument to allow the old behavior to be specified.
+
+ - Allow the library modules imported by an SConscript file to get at
+ all of the normally-available global functions and variables by saying
+ "from SCons.Script import *".
+
+ - Add a --debug=memoizer option to print Memoizer hit/mass statistics.
+
+ - Allow more than one --debug= option to be set at a time.
+
+ - Change --debug=count to report object counts before and after
+ reading SConscript files and before and after building targets.
+
+ - Change --debug=memory output to line up the numbers and to better
+ match (more or less) the headers on the --debug=count columns.
+
+ - Speed things up when there are lists of targets and/or sources by
+ getting rid of some N^2 walks of the lists involved.
+
+ - Cache evaluation of LazyActions so we don't create a new object
+ for each invocation.
+
+ - When scanning, don't create Nodes for include files that don't
+ actually exist on disk.
+
+ - Make supported global variables CScanner, DScanner, ProgramScanner and
+ SourceFileScanner. Make SourceFileScanner.add_scanner() a supported
+ part of the public interface. Keep the old SCons.Defaults.*Scan names
+ around for a while longer since some people were already using them.
+
+ - By default, don't scan directories for on-disk files. Add a
+ DirScanner global scanner that can be used in Builders or Command()
+ calls that want source directory trees scanned for on-disk changes.
+ Have the Tar() and Zip() Builders use the new DirScanner to preserve
+ the behavior of rebuilding a .tar or .zip file if any file or
+ directory under a source tree changes. Add Command() support for
+ a source_scanner keyword argument to Command() that can be set to
+ DirScanner to get this behavior.
+
+ - Documentation changes: Explain that $CXXFLAGS contains $CCFLAGS
+ by default. Fix a bad target_factory example in the man page.
+ Add appendices to the User's Guide to cover the available Tools,
+ Builders and construction variables. Comment out the build of
+ the old Python 10 paper, which doesn't build on all systems and
+ is old enough at this point that it probably isn't worth the
+ effort to make it do so.
+
+ From Wayne Lee:
+
+ - Avoid "maximum recursion limit" errors when removing $(-$) pairs
+ from long command lines.
+
+ From Clive Levinson:
+
+ - Make ParseConfig() recognize and add -mno-cygwin to $LINKFLAGS and
+ $CCFLAGS, and -mwindows to $LINKFLAGS.
+
+ From Michael McCracken:
+
+ - Add a new "applelink" tool to handle the things like Frameworks and
+ bundles that Apple has added to gcc for linking.
+
+ - Use more appropriate default search lists of linkers, compilers and
+ and other tools for the 'darwin' platform.
+
+ - Add a LoadableModule Builder that builds a bundle on Mac OS X (Darwin)
+ and a shared library on other systems.
+
+ - Improve SWIG tests for use on Mac OS X (Darwin).
+
+ From Elliot Murphy:
+
+ - Enhance the tests to guarantee persistence of ListOption
+ values in saved options files.
+
+ - Supply the help text when -h is used with the -u, -U or -D options.
+
+ From Christian Neeb:
+
+ - Fix the Java parser's handling of string definitions to avoid ignoring
+ subsequent code.
+
+ From Han-Wen Nienhuys:
+
+ - Optimize variable expansion by: using the re.sub() method (when
+ possible); not using "eval" for variables for which we can fetch the
+ value directory; avoiding slowing substitution logic when there's no
+ '$' in the string.
+
+ From Gary Oberbrunner:
+
+ - Add an Environment.Dump() method to print the contents of a
+ construction environment.
+
+ - Allow $LIBS (and similar variables) to contain explicit File Nodes.
+
+ - Change ParseConfig to add the found library names directly to the
+ $LIBS variable, instead of returning them.
+
+ - Add ParseConfig() support for the -framework GNU linker option.
+
+ - Add a PRINT_CMD_LINE_FUNC construction variable to allow people
+ to filter (or log) command-line output.
+
+ - Print an internal Python stack trace in response to an otherwise
+ unexplained error when --debug=stacktrace is specified.
+
+ - Add a --debug=findlibs option to print what's happening when
+ the scanner is searching for libraries.
+
+ - Allow Tool specifications to be passed a dictionary of keyword
+ arguments.
+
+ - Support an Options default value of None, in which case the variable
+ will not be added to the construction environment unless it's set
+ explicitly by the user or from an Options file.
+
+ - Avoid copying __builtin__ values into a construction environment's
+ dictionary when evaluating construction variables.
+
+ - Add a new cross-platform intelc.py Tool that can detect and
+ configure the Intel C++ v8 compiler on both Windows, where it's
+ named icl, and Linux, where it's named icc. It also checks that
+ the directory specified in the Windows registry exists, and sets a
+ new $INTEL_C_COMPILER_VERSION construction variable to identify the
+ version being used. (Niall Douglas contributed an early prototype
+ of parts of this module.)
+
+ - Fix the private Conftest._Have() function so it doesn't change
+ non-alphanumeric characters to underscores.
+
+ - Supply a better error message when a construction variable expansion
+ has an unknown attribute.
+
+ - Documentation changes: Update the man page to describe use of
+ filenames or Nodes in $LIBS.
+
+ From Chris Pawling:
+
+ - Have the linkloc tool use $MSVS_VERSION to select the Microsoft
+ Visual Studio version to use.
+
+ From Kevin Quick:
+
+ - Fix the Builder name returned from ListBuilders and other instances
+ of subclasses of the BuilderBase class.
+
+ - Add Builders and construction variables to support rpcgen:
+ RPCGenClient(), RPCGenHeader(), RPCGenService(), RPCGenXDR(),
+ $RPCGEN, $RPCGENFLAGS, $RPCGENCLIENTFLAGS, $RPCGENHEADERFLAGS,
+ $RPCGENSERVICEFLAGS, $RPCGENXDRFLAGS.
+
+ - Update the man page to document that prefix and suffix Builder
+ keyword arguments can be strings, callables or dictionaries.
+
+ - Provide more info in the error message when a user tries to build
+ a target multiple ways.
+
+ - Fix Delete() when a file doesn't exist and must_exist=1. (We were
+ unintentionally dependent on a bug in versions of the Python shutil.py
+ module prior to Python 2.3, which would generate an exception for
+ a nonexistent file even when ignore_errors was set.)
+
+ - Only replace a Node's builder with a non-null source builder.
+
+ - Fix a stack trace when a suffix selection dictionary is passed
+ an empty source file list.
+
+ - Allow optional names to be attached to Builders, for default
+ Builders that don't get attached to construction environments.
+
+ - Fix problems with Parallel Task Exception handling.
+
+ - Build targets in an associated BuildDir even if there are targets
+ or subdirectories locally in the source directory.
+
+ - If a FunctionAction has a callable class as its underlying Python
+ function, use its strfunction() method (if any) to display the
+ action.
+
+ - Fix handling when BuildDir() exists but is unwriteable. Add
+ "Stop." to those error messages for consistency.
+
+ - Catch incidents of bad builder creation (without an action) and
+ supply meaningful error messages.
+
+ - Fix handling of src_suffix values that aren't extensions (don't
+ begin with a '.').
+
+ - Don't retrieve files from a CacheDir, but report what would happen,
+ when the -n option is used.
+
+ - Use the source_scanner from the target Node, not the source node
+ itself.
+
+ - Internal Scanners fixes: Make sure Scanners are only passed Nodes.
+ Fix how a Scanner.Selector called its base class initialization.
+ Make comparisons of Scanner objects more robust. Add a name to
+ an internal default ObjSourceScanner.
+
+ - Add a deprecated warning for use of the old "scanner" keyword argument
+ to Builder creation.
+
+ - Improve the --debug=explain message when the build action changes.
+
+ - Test enhancements in SourceCode.py, option-n.py, midl.py. Better
+ Command() and Scanner test coverage. Improved test infrastructure
+ for -c output.
+
+ - Refactor the interface between Action and Executor objects to treat
+ Actions atomically.
+
+ - The --debug=presub option will now report the pre-substitution
+ each action seprately, instead of reporting the entire list before
+ executing the actions one by one.
+
+ - The --debug=explain option explaining a changed action will now
+ (more correctly) show pre-substitution action strings, instead of
+ the commands with substituted file names.
+
+ - A Node (file) will now be rebuilt if its PreAction or PostAction
+ actions change.
+
+ - Python Function actions now have their calling signature (target,
+ source, env) reported correctly when displayed.
+
+ - Fix BuildDir()/build_dir handling when the build_dir is underneath
+ the source directory and trying to use entries from the build_dir
+ as sources for other targets in the build-dir.
+
+ - Fix hard-coding of JDK path names in various Java tests.
+
+ - Handle Python stack traces consistently (stop at the SConscript stack
+ frame, by default) even if the Python source code isn't available.
+
+ - Improve the performance of the --debug={tree,dtree} options.
+
+ - Add --debug=objects logging of creation of OverrideWarner,
+ EnvironmentCopy and EnvironmentOverride objects.
+
+ - Fix command-line expansion of Python Value Nodes.
+
+ - Internal cleanups: Remove an unnecessary scan argument. Associate
+ Scanners only with Builders, not nodes. Apply overrides once when
+ a Builder is called, not in multiple places. Cache results from the
+ Node.FS.get_suffix() and Node.get_build_env() methods. Use the Python
+ md5 modules' hexdigest() method, if there is one. Have Taskmaster
+ call get_stat() once for each Node and re-use the value instead of
+ calling it each time it needs the value. Have Node.depends_on()
+ re-use the list from the children() method instead of calling it
+ multiple times.
+
+ - Use the correct scanner if the same source file is used for targets in
+ two different environments with the same path but different scanners.
+
+ - Collect logic for caching values in memory in a Memoizer class,
+ which cleans up a lot of special-case code in various methods and
+ caches additional values to speed up most configurations.
+
+ - Add a PathAccept validator to the list of new canned PathOption
+ validators.
+
+ From Jeff Squyres:
+
+ - Documentation changes: Use $CPPDEFINES instead of $CCFLAGS in man
+ page examples.
+
+ From Levi Stephen:
+
+ - Allow $JARCHDIR to be expanded to other construction variables.
+
+ From Christoph Wiedemann:
+
+ - Add an Environment.SetDefault() method that only sets values if
+ they aren't already set.
+
+ - Have the qt.py Tool not override variables already set by the user.
+
+ - Add separate $QT_BINPATH, $QT_CPPPATH and $QT_LIBPATH variables
+ so these can be set individually, instead of being hard-wired
+ relative to $QTDIR.
+
+ - The %TEMP% and %TMP% external environment variables are now propagated
+ automatically to the command execution environment on Windows systems.
+
+ - A new --config= command-line option allows explicit control of
+ of when the Configure() tests are run: --config=force forces all
+ checks to be run, --config=cache uses all previously cached values,
+ --config=auto (the default) runs tests only when dependency analysis
+ determines it's necessary.
+
+ - The Configure() subsystem can now write a config.h file with values
+ like HAVE_STDIO_H, HAVE_LIBM, etc.
+
+ - The Configure() subsystem now executes its checks silently when the
+ -Q option is specified.
+
+ - The Configure() subsystem now reports if a test result is being
+ taken from cache, and prints the standard output and error output
+ of tests even when cached.
+
+ - Configure() test results are now reported as "yes" or "no" instead of
+ "ok" or "failed."
+
+ - Fixed traceback printing when calling the env.Configure() method
+ instead of the Configure() global function.
+
+ - The Configure() subsystem now caches build failures in a .sconsign
+ file in the subdirectory, not a .cache file. This may cause
+ tests to be re-executed the first time after you install 0.97.
+
+ - Additional significant internal cleanups in the Configure() subsystem
+ and its tests.
+
+ - Have the Qt Builder make uic-generated files dependent on the .ui.h
+ file, if one exists.
+
+ - Add a test to make sure that SCons source code does not contain
+ try:-except: blocks that catch all errors, which potentially catch
+ and mask keyboard interrupts.
+
+ - Fix us of TargetSignatures('content') with the SConf subsystem.
+
+ From Russell Yanofsky:
+
+ - Add support for the Metrowerks Codewarrior compiler and linker
+ (mwcc and mwld).
+
+
+
+RELEASE 0.96.1 - Mon, 23 Aug 2004 12:55:50 +0000
+
+ From Craig Bachelor:
+
+ - Handle white space in the executable Python path name within in MSVS
+ project files by quoting the path.
+
+ - Correct the format of a GUID string in a solution (.dsw) file so
+ MSVS can correctly "build enable" a project.
+
+ From Steven Knight:
+
+ - Add a must_exist flag to Delete() to let the user control whether
+ it's an error if the specified entry doesn't exist. The default
+ behavior is now to silently do nothing if it doesn't exist.
+
+ - Package up the new Platform/darwin.py, mistakenly left out of 0.96.
+
+ - Make the scons.bat REM statements into @REM so they aren't printed.
+
+ - Make the SCons packaging SConscript files platform independent.
+
+ From Anthony Roach:
+
+ - Fix scanning of pre-compiled header (.pch) files for #includes,
+ broken in 0.96.
+
+
+
+RELEASE 0.96 - Wed, 18 Aug 2004 13:36:40 +0000
+
+ From Chad Austin:
+
+ - Make the CacheDir() directory if it doesn't already exist.
+
+ - Allow construction variable substitutions in $LIBS specifications.
+
+ - Allow the emitter argument to a Builder() to be or expand to a list
+ of emitter functions, which will be called in sequence.
+
+ - Suppress null values in construction variables like $LIBS that use
+ the internal _concat() function.
+
+ - Remove .dll files from the construction variables searched for
+ libraries that can be fed to Win32 compilers.
+
+ From Chad Austin and Christoph Wiedemann:
+
+ - Add support for a $RPATH variable to supply a list of directories
+ to search for shared libraries when linking a program. Used by
+ the GNU and IRIX linkers (gnulink and sgilink).
+
+ From Charles Crain:
+
+ - Restore the ability to do construction variable substitutions in all
+ kinds of *PATH variables, even when the substitution returns a Node
+ or other object.
+
+ From Tom Epperly:
+
+ - Allow the Java() Builder to take more than one source directory.
+
+ From Ralf W. Grosse-Kunstleve:
+
+ - Have SConsignFile() use, by default, a custom "dblite.py" that we can
+ control and guarantee to work on all Python versions (or nearly so).
+
+ From Jonathan Gurley:
+
+ - Add support for the newer "ifort" versions of the Intel Fortran
+ Compiler for Linux.
+
+ From Bob Halley:
+
+ - Make the new *FLAGS variable type work with copied Environments.
+
+ From Chris Hoeppler:
+
+ - Initialize the name of a Scanner.Classic scanner correctly.
+
+ From James Juhasz:
+
+ - Add support for the .dylib shared library suffix and the -dynamiclib
+ linker option on Mac OS X.
+
+ From Steven Knight:
+
+ - Add an Execute() method for executing actions directly.
+
+ - Support passing environment override keyword arguments to Command().
+
+ - Fix use of $MSVS_IGNORE_IDE_PATHS, which was broken when we added
+ support for $MSVS_USE_MFC_DIRS last release.
+
+ - Make env.Append() and env.Prepend() act like the underlying Python
+ behavior when the variable being appended to is a UserList object.
+
+ - Fix a regression that prevented the Command() global function in
+ 0.95 from working with command-line strings as actions.
+
+ - Fix checking out a file from a source code management system when
+ the env.SourceCode() method was called with an individual file name
+ or node, not a directory name or node.
+
+ - Enhance the Task.make_ready() method to create a list of the
+ out-of-date Nodes for the task for use by the wrapping interface.
+
+ - Allow Scanners to pull the list of suffixes from the construction
+ environment when the "skeys" keyword argument is a string containing
+ a construction variable to be expanded.
+
+ - Support new $CPPSUFFIXES, $DSUFFIXES $FORTRANSUFFIXES, and
+ $IDLSUFFIXES. construction variables that contain the default list
+ of suffixes to be scanned by a given type of scanner, allowing these
+ suffix lists to be easily added to or overridden.
+
+ - Speed up Node creation when calling a Builder by comparing whether two
+ Environments are the same object, not if their underlying dictionaries
+ are equivalent.
+
+ - Add a --debug=explain option that reports the reason(s) why SCons
+ thinks it must rebuild something.
+
+ - Add support for functions that return platform-independent Actions
+ to Chmod(), Copy(), Delete(), Mkdir(), Move() and Touch() files
+ and/or directories. Like any other Actions, the returned Action
+ object may be executed directly using the Execute() global function
+ or env.Execute() environment method, or may be used as a Builder
+ action or in an env.Command() action list.
+
+ - Add support for the strfunction argument to all types of Actions:
+ CommandAction, ListAction, and CommandGeneratorAction.
+
+ - Speed up turning file system Nodes into strings by caching the
+ values after we're finished reading the SConscript files.
+
+ - Have ParseConfig() recognize and supporting adding the -Wa, -Wl,
+ and -Wp, flags to ASFLAGS, LINKFLAGS and CPPFLAGS, respectively.
+
+ - Change the .sconsign format and the checks for whether a Node is
+ up-to-date to make dependency checks more efficient and correct.
+
+ - Add wrapper Actions to SCons.Defaults for $ASCOM, $ASPPCOM, $LINKCOM,
+ $SHLINKCOM, $ARCOM, $LEXCOM and $YACCCOM. This makes it possible
+ to replace the default print behavior with a custom strfunction()
+ for each of these.
+
+ - When a Node has been built, don't walk the whole tree back to delete
+ the parents's implicit dependencies, let returning up the normal
+ Taskmaster descent take care of it for us.
+
+ - Add documented support for separate target_scanner and source_scanner
+ arguments to Builder creation, which allows different scanners to
+ be applied to source files
+
+ - Don't re-install or (re-generate) .h files when a subsidiary #included
+ .h file changes. This eliminates incorrect circular dependencies
+ with .h files generated from other source files.
+
+ - Slim down the internal Sig.Calculator class by eliminating methods
+ whose functionality is now covered by Node methods.
+
+ - Document use of the target_factory and source_factory keyword
+ arguments when creating Builder objects. Enhance Dir Nodes so that
+ they can be created with user-specified Builder objects.
+
+ - Don't blow up with stack trace when the external $PATH environment
+ variable isn't set.
+
+ - Make Builder calls return lists all the time, even if there's only
+ one target. This keeps things consistent and easier to program to
+ across platforms.
+
+ - Add a Flatten() function to make it easier to deal with the Builders
+ all returning lists of targets, not individual targets.
+
+ - Performance optimizations in Node.FS.__doLookup().
+
+ - Man page fixes: formatting typos, misspellings, bad example.
+
+ - User's Guide fixes: Fix the signatures of the various example
+ *Options() calls. Triple-quote properly a multi-line Split example.
+
+ - User's Guide additions: Chapter describing File and Directory
+ Nodes. Section describing declarative nature of SCons functions in
+ SConscript files. Better organization and clarification of points
+ raised by Robert P. J. Day. Chapter describing SConf (Autoconf-like)
+ functionality. Chapter describing how to install Python and
+ SCons. Chapter describing Java builds.
+
+ From Chris Murray:
+
+ - Add a .win32 attribute to force file names to expand with
+ Windows backslash path separators.
+
+ - Fix escaping file names on command lines when the expansion is
+ concatenated with another string.
+
+ - Add support for Fortran 90 and Fortran 95. This adds $FORTRAN*
+ variables that specify a default compiler, command-line, flags,
+ etc. for all Fortran versions, plus separate $F90* and $F95*
+ variables for when different compilers/flags/etc. must be specified
+ for different Fortran versions.
+
+ - Have individual tools that create libraries override the default
+ $LIBPREFIX and $LIBSUFFIX values set by the platform. This makes
+ it easier to use Microsoft Visual Studio tools on a CygWin platform.
+
+ From Gary Oberbrunner:
+
+ - Add a --debug=presub option to print actions prior to substitution.
+
+ - Add a warning upon use of the override keywords "targets" and
+ "sources" when calling Builders. These are usually mistakes which
+ are otherwise silently (and confusingly) turned into construction
+ variable overrides.
+
+ - Try to find the ICL license file path name in the external environment
+ and the registry before resorting to the hard-coded path name.
+
+ - Add support for fetching command-line keyword=value arguments in
+ order from an ARGLIST list.
+
+ - Avoid stack traces when trying to read dangling symlinks.
+
+ - Treat file "extensions" that only contain digits as part of the
+ file basename. This supports version numbers as part of shared
+ library names, for example.
+
+ - Avoid problems when there are null entries (None or '') in tool
+ lists or CPPPATH.
+
+ - Add an example and explanation of how to use "tools = ['default', ..."
+ when creating a construction environment.
+
+ - Add a section describing File and Directory Nodes and some of their
+ attributes and methods.
+
+ - Have ParseConfig() add a returned -pthread flag to both $CCFLAGS
+ and $LINKFLAGS.
+
+ - Fix some test portability issues on Mac OS X (darwin).
+
+ From Simon Perkins:
+
+ - Fix a bug introduced in building shared libraries under MinGW.
+
+ From Kevin Quick:
+
+ - Handling SCons exceptions according to Pythonic standards.
+
+ - Fix test/chained-build.py on systems that execute within one second.
+
+ - Fix tests on systems where 'ar' warns about archive creation.
+
+ From Anthony Roach:
+
+ - Fix use of the --implicit-cache option with timestamp signatures.
+
+ - If Visual Studio is installed, assume the C/C++ compiler, the linker
+ and the MIDL compiler that comes with it are available, too.
+
+ - Better error messages when evaluating a construction variable
+ expansion yields a Python syntax error.
+
+ - Change the generation of PDB files when using Visual Studio from
+ compile time to link time.
+
+ From sam th:
+
+ - Allow SConf.CheckLib() to search a list of libraries, like the
+ Autoconf AC_SEARCH_LIBS macro.
+
+ - Allow the env.WhereIs() method to take a "reject" argument to
+ let it weed out specific path names.
+
+ From Christoph Wiedemann:
+
+ - Add new Moc() and Uic() Builders for more explicit control over
+ Qt builds, plus new construction variables to control them:
+ $QT_AUTOSCAN, $QT_DEBUG, $QT_MOCCXXPREFIX, $QT_MOCCXXSUFFIX,
+ $QT_MOCHPREFIX, $QT_MOCHSUFFIX, $QT_UICDECLPREFIX, $QT_UICDECLSUFFIX,
+ $QT_UICIMPLPREFIX, $QT_UICIMPLSUFFIX and $QT_UISUFFIX.
+
+ - Add a new single_source keyword argument for Builders that enforces
+ a single source file on calls to the Builder.
+
+
+
+RELEASE 0.95 - Mon, 08 Mar 2004 06:43:20 -0600
+
+ From Chad Austin:
+
+ - Replace print statements with calls to sys.stdout.write() so output
+ lines stay together when -j is used.
+
+ - Add portability fixes for a number of tests.
+
+ - Accomodate the fact that Cygwin's os.path.normcase() lies about
+ the underlying system being case-sensitive.
+
+ - Fix an incorrect _concat() call in the $RCINCFLAGS definition for
+ the mingw Tool.
+
+ - Fix a problem with the msvc tool with Python versions prior to 2.3.
+
+ - Add support for a "toolpath" Tool() and Environment keyword that
+ allows Tool modules to be found in specified local directories.
+
+ - Work around Cygwin Python's silly fiction that it's using a
+ case-sensitive file system.
+
+ - More robust handling of data in VCComponents.dat.
+
+ - If the "env" command is available, spawn commands with the more
+ general "env -" instead of "env -i".
+
+ From Kerim Borchaev:
+
+ - Fix a typo in a msvc.py's registry lookup: "VCComponents.dat", not
+ "VSComponents.dat".
+
+ From Chris Burghart:
+
+ - Fix the ability to save/restore a PackageOption to a file.
+
+ From Steve Christensen:
+
+ - Update the MSVS .NET and MSVC 6.0/7.0 path detection.
+
+ From David M. Cooke:
+
+ - Make the Fortran scanner case-insensitive for the INCLUDE string.
+
+ From Charles Crain:
+
+ - If no version of MSVC is detected but the tool is specified,
+ use the MSVC 6.0 paths by default.
+
+ - Ignore any "6.1" version of MSVC found in the registry; this is a
+ phony version number (created by later service packs?) and would
+ throw off the logic if the user had any non-default paths configure.
+
+ - Correctly detect if the user has independently configured the MSVC
+ "include," "lib" or "path" in the registry and use the appropriate
+ values. Previously, SCons would only use the values if all three
+ were set in the registry.
+
+ - Make sure side-effect nodes are prepare()d before building their
+ corresponding target.
+
+ - Preserve the ability to call BuildDir() multiple times with the
+ same target and source directory arguments.
+
+ From Andy Friesen:
+
+ - Add support for the Digital Mars "D" programming language.
+
+ From Scott Lystig Fritchie:
+
+ - Fix the ability to use a custom _concat() function in the
+ construction environment when calling _stripixes().
+
+ - Make the message about ignoring a missing SConscript file into a
+ suppressable Warning, not a hard-coded sys.stderr.write().
+
+ - If a builder can be called multiple times for a target (because
+ the sources and overrides are identical, or it's a builder with the
+ "multi" flag set), allow the builder to be called through multiple
+ environments so long as the builders have the same signature for
+ the environments in questions (that is, they're the same action).
+
+ From Bob Halley:
+
+ - When multiple targets are built by a single action, retrieve all
+ of them from cache, not just the first target, and exec the build
+ command if any of the targets isn't present in the cache.
+
+ From Zephaniah Hull:
+
+ - Fix command-line ARGUMENTS with multiple = in them.
+
+ From Steven Knight:
+
+ - Fix EnsureSConsVersion() so it checks against the SCons version,
+ not the Python version, on Pythons with sys.version_info.
+
+ - Don't swallow the AttributeError when someone uses an expansion like
+ $TARGET.bak, so we can supply a more informative error message.
+
+ - Fix an odd double-quote escape sequence in the man page.
+
+ - Fix looking up a naked drive letter as a directory (Dir('C:')).
+
+ - Support using File nodes in the LIBS construction variable.
+
+ - Allow the LIBS construction variable to be a single string or File
+ node, not a list, when only one library is needed.
+
+ - Fix typos in the man page: JAVACHDIR => JARCHDIR; add "for_signature"
+ to the __call__() example in the "Variable Substitution" section.
+
+ - Correct error message spellings of "non-existant" to "non-existent."
+
+ - When scanning for libraries to link with, don't append $LIBPREFIXES
+ or $LIBSUFFIXES values to the $LIBS values if they're already present.
+
+ - Add a ZIPCOMPRESSION construction variable to control whether the
+ internal Python action for the Zip Builder compresses the file or
+ not. The default value is zipfile.ZIP_DEFLATED, which generates
+ a compressed file.
+
+ - Refactor construction variable expansion to support recursive
+ expansion of variables (e.g. CCFLAGS = "$CCFLAGS -g") without going
+ into an infinite loop. Support this in all construction variable
+ overrides, as well as when copying Environments.
+
+ - Fix calling Configure() from more than one subsidiary SConscript file.
+
+ - Fix the env.Action() method so it returns the correct type of
+ Action for its argument(s).
+
+ - Fix specifying .class files as input to JavaH with the .class suffix
+ when they weren't generated using the Java Builder.
+
+ - Make the check for whether all of the objects going into a
+ SharedLibrary() are shared work even if the object was built in a
+ previous run.
+
+ - Supply meaningful error messages, not stack traces, if we try to add
+ a non-Node as a source, dependency, or ignored dependency of a Node.
+
+ - Generate MSVS Project files that re-invoke SCons properly regardless
+ of whether the file was built via scons.bat or scons.py.
+ (Thanks to Niall Douglas for contributing code and testing.)
+
+ - Fix TestCmd.py, runtest.py and specific tests to accomodate being
+ run from directories whose paths include white space.
+
+ - Provide a more useful error message if a construction variable
+ expansion contains a syntax error during evaluation.
+
+ - Fix transparent checkout of implicit dependency files from SCCS
+ and RCS.
+
+ - Added new --debug=count, --debug=memory and --debug=objects options.
+ --debug=count and --debug=objects only print anything when run
+ under Python 2.1 or later.
+
+ - Deprecate the "overrides" keyword argument to Builder() creation
+ in favor of using keyword argument values directly (like we do
+ for builder execution and the like).
+
+ - Always use the Builder overrides in substitutions, not just if
+ there isn't a target-specific environment.
+
+ - Add new "rsrcpath" and "rsrcdir" and attributes to $TARGET/$SOURCE,
+ so Builder command lines can find things in Repository source
+ directories when using BuildDir.
+
+ - Fix the M4 Builder so that it chdirs to the Repository directory
+ when the input file is in the source directory of a BuildDir.
+
+ - Save memory at build time by allowing Nodes to delete their build
+ environments after they've been built.
+
+ - Add AppendUnique() and PrependUnique() Environment methods, which
+ add values to construction variables like Append() and Prepend()
+ do, but suppress any duplicate elements in the list.
+
+ - Allow the 'qt' tool to still be used successfully from a copied
+ Environment. The include and library directories previously ended up
+ having the same string re-appended to the end, yielding an incorrect
+ path name.
+
+ - Supply a more descriptive error message when the source for a target
+ can't be found.
+
+ - Initialize all *FLAGS variables with objects do the right thing with
+ appending flags as strings or lists.
+
+ - Make things like ${TARGET.dir} work in *PATH construction variables.
+
+ - Allow a $MSVS_USE_MFC_DIRS construction variable to control whether
+ ATL and MFC directories are included in the default INCLUDE and
+ LIB paths.
+
+ - Document the dbm_module argument to the SConsignFile() function.
+
+ From Vincent Risi:
+
+ - Add support for the bcc32, ilink32 and tlib Borland tools.
+
+ From Anthony Roach:
+
+ - Supply an error message if the user tries to configure a BuildDir
+ for a directory that already has one.
+
+ - Remove documentation of the still-unimplemented -e option.
+
+ - Add -H help text listing the legal --debug values.
+
+ - Don't choke if a construction variable is a non-string value.
+
+ - Build Type Libraries in the target directory, not the source
+ directory.
+
+ - Add an appendix to the User's Guide showing how to accomplish
+ various common tasks in Python.
+
+ From Greg Spencer:
+
+ - Add support for Microsoft Visual Studio 2003 (version 7.1).
+
+ - Evaluate $MSVSPROJECTSUFFIX and $MSVSSOLUTIONSUFFIX when the Builder
+ is invoked, not when the tool is initialized.
+
+ From Christoph Wiedemann:
+
+ - When compiling Qt, make sure the moc_*.cc files are compiled using
+ the flags from the environment used to specify the target, not
+ the environment that first has the Qt Builders attached.
+
+
+
+RELEASE 0.94 - Fri, 07 Nov 2003 05:29:48 -0600
+
+ From Hartmut Goebel:
+
+ - Add several new types of canned functions to help create options:

+ PathOption().
+

+
+ - Fix use of CPPDEFINES with C++ source files.
+
+ - Fix env.Append() when the operand is an object with a __cmp__()
+ method (like a Scanner instance).
+
+ - Fix subclassing the Environment and Scanner classes.
+
+ - Add BUILD_TARGETS, COMMAND_LINE_TARGETS and DEFAULT_TARGETS variables.
+
+ From Steve Leblanc:
+
+ - SGI fixes: Fix C++ compilation, add a separate Tool/sgic++.py module.

+
+ From J.T. Conklin:
+
+ - On POSIX, execute commands with the more modern os.spawnvpe()
+ function, if it's available.
+
+ - Scan .S, .spp and .SPP files for C preprocessor dependencies.
+
+ - Refactor the Job.Parallel() class to use a thread pool without a
+ condition variable. This improves parallel build performance and
+ handles keyboard interrupts properly when -j is used.
+
+ From Charles Crain:
+
+ - Add support for a JARCHDIR variable to control changing to a
+ directory using the jar -C option.
+
+ - Add support for detecting Java manifest files when using jar,
+ and specifying them using the jar m flag.
+
+ - Fix some Python 2.2 specific things in various tool modules.
+
+ - Support directories as build sources, so that a rebuild of a target
+ can be triggered if anything underneath the directory changes.
+
+ - Have the scons.bat and scons.py files look for the SCons modules
+ in site-packages as well.
+
+ From Christian Engel:
+
+ - Support more flexible inclusion of separate C and C++ compilers.
+
+ - Use package management tools on AIX and Solaris to find where
+ the comilers are installed, and what version they are.
+
+ - Add support for CCVERSION and CXXVERSION variables for a number
+ of C and C++ compilers.
+
+ From Sergey Fogel:
+
+ - Add test cases for the new capabilities to run bibtex and to rerun
+ latex as needed.
+
+ From Ralf W. Grosse-Kunstleve:
+
+ - Accomodate anydbm modules that don't have a sync() method.
+
+ - Allow SConsignFile() to take an argument specifying the DBM
+ module to be used.
+
+ From Stephen Kennedy:
+
+ - Add support for a configurable global .sconsign.dbm file which
+ can be used to avoid cluttering each directory with an individual
+ .sconsign file.
+
+ From John Johnson:
+
+ - Fix (re-)scanning of dependencies in generated or installed
+ header files.
+
+ From Steven Knight:
+
+ - The -Q option suppressed too many messages; fix it so that it only
+ suppresses the Reading/Building messages.
+
+ - Support #include when there's no space before the opening quote
+ or angle bracket.
+
+ - Accomodate alphanumeric version strings in EnsurePythonVersion().
+
+ - Support arbitrary expansion of construction variables within
+ file and directory arguments to Builder calls and Environment methods.
+
+ - Add Environment-method versions of the following global functions:

+
+ - Add the following global functions that correspond to the same-named
+ Environment methods: AlwaysBuild(), Command(), Depends(), Ignore(),
+ Install(), InstallAs(), Precious(), SideEffect() and SourceCode().
+
+ - Add the following global functions that correspond to the default
+ Builder methods supported by SCons: CFile(), CXXFile(), DVI(), Jar(),
+ Java(), JavaH(), Library(), M4(), MSVSProject(), Object(), PCH(),
+ PDF(), PostScript(), Program(), RES(), RMIC(), SharedLibrary(),
+ SharedObject(), StaticLibrary(), StaticObject(), Tar(), TypeLibrary()
+ and Zip().
+
+ - Rearrange the man page to show construction environment methods and
+ global functions in the same list, and to explain the difference.
+
+ - Alphabetize the explanations of the builder methods in the man page.
+
+ - Rename the Environment.Environment class to Enviroment.Base.
+ Allow the wrapping interface to extend an Environment by using its own
+ subclass of Environment.Base and setting a new Environment.Environment
+ variable as the calling entry point.
+
+ - Deprecate the ParseConfig() global function in favor of a same-named
+ construction environment method.
+
+ - Allow the Environment.WhereIs() method to take explicit path and
+ pathext arguments (like the underlying SCons.Util.WhereIs() function).
+
+ - Remove the long-obsolete {Get,Set}CommandHandler() functions.
+
+ - Enhance env.Append() to suppress null values when appropriate.
+
+ - Fix ParseConfig() so it works regardless of initial construction
+ variable values.
+
+ Extend CheckHeader(), CheckCHeader(), CheckCXXHeader() and

+ #included in the test. The last one in the list is assumed to be
+ the one being checked for. (Prototype code contributed by Gerard
+ Patel and Niall Douglas).
+

+ the current version of Python.
+
+ - First release of the User's Guide (finally, and despite a lot
+ of things still missing from it...).
+
+ From Clark McGrew:
+
+ - Generalize the action for .tex files so that it will decide whether
+ a file is TeX or LaTeX, check the .aux output to decide if it should
+ run bibtex, and check the .log output to re-run LaTeX if needed.
+
+ From Bram Moolenaar:
+
+ - Split the non-SCons-specific functionality from SConf.py to a new,
+ re-usable Conftest.py module.

+
+ From Marko Rauhamaa:
+
+ - Have the closing message say "...terminated because of errors" if
+ there were any.
+
+ From Anthony Roach:
+
+ - On Win32 systems, only use "rm" to delete files if Cygwin is being
+ used. ("rm" doesn't understand Win32-format path names.)
+
+ From Christoph Wiedemann:
+
+ - Fix test/SWIG.py to find the Python include directory in all cases.

+
+ - Update the Debian package so it uses Python 2.2 and more closely
+ resembles the currently official Debian packaging info.
+
+ From Gerard Patel
+
+ - When the yacc -d flag is used, take the .h file base name from the
+ target .c file, not the source (matching what yacc does).
+
+
+
+RELEASE 0.91 - Thu, 14 Aug 2003 13:00:44 -0500
+
+ From Chad Austin:
+
+ - Support specifying a list of tools when calling Environment.Copy().
+
+ - Give a Value Nodes a timestamp of the system time when they're
+ created, so they'll work when using timestamp-based signatures.
+
+ - Add a DefaultEnvironment() function that only creates a default
+ environment on-demand (for fetching source files, e.g.).
+
+ - Portability fix for test/M4.py.
+
+ From Steven Knight:
+
+ - Tighten up the scons -H help output.
+
+ - When the input yacc file ends in .yy and the -d flag is specified,
+ recognize that a .hpp file (not a .h file) will be created.
+
+ - Make builder prefixes work correctly when deducing a target
+ from a source file name in another directory.
+
+ - Documentation fixes: typo in the man page; explain up-front about
+ not propagating the external environment.
+
+ - Use "cvs co -d" instead of "cvs co -p >" when checking out something
+ from CVS with a specified module name. This avoids zero-length
+ files when there is a checkout error.

+ - Add an "sconsign" script to print the contents of .sconsign files.
+
+ - Speed up maintaining the various lists of Node children by using
+ dictionaries to avoid "x in list" searches.
+
+ - Cache the computed list of Node children minus those being Ignored
+ so it's only calculated once.
+
+ - Fix use of the --cache-show option when building a Program()
+ (or using any other arbitrary action) by making sure all Action
+ instances have strfunction() methods.
+
+ - Allow the source of Command() to be a directory.
+
+ - Better error handling of things like raw TypeErrors in SConscripts.
+
+ - When installing using "setup.py install --prefix=", suppress the
+ distutils warning message about adding the (incorrect) library
+ directory to your search path.
+
+ - Correct the spelling of the "validater" option to "validator."
+ Add a DeprecatedWarning when the old spelling is used.
+
+ - Allow a Builder's emitter to be a dictionary that maps source file
+ suffixes to emitter functions, using the suffix of the first file
+ in the source list to pick the right one.
+
+ - Refactor the creation of the Program, *Object and *Library Builders
+ so that they're moved out of SCons.Defaults and created on demand.
+
+ - Don't split SConscript file names on white space.
+
+ - Document the SConscript function's "dirs" and "name" keywords.
+
+ - Remove the internal (and superfluous) SCons.Util.argmunge() function.
+
+ - Add /TP to the default CXXFLAGS for msvc, so it can compile all

+ to control when a temporary file is used for long command lines.
+
+ - Make how we build .rpm packages not depend on the installation

+
+ - Add support for SWIG.
+
+ From Bram Moolenaar:
+
+ - Test portability fixes for FreeBSD.
+
+ From Gary Oberbrunner:

+
+ - Fix the value returned by the Node.prevsiginfo() method to conform

+
+ - Documentation fixes: better explain the AlwaysBuild() function.

+
+ - Have the gcc Tool actually use gcc in preference to cc.

+ - Fix man page bugs: remove duplicate AddPostAction() description;
+ document no_import_lib; mention that CPPFLAGS does not contain
+ $_CPPINCFLAGS; mention that F77FLAGS does not contain $_F77INCFLAGS;
+ mention that LINKFLAGS and SHLINKFLAGS contains neither $_LIBFLAGS
+ nor $_LIBDIRFLAGS.
+
+ - Eliminate a dependency on the distutils.fancy_getopt module by
+ copying and pasting its wrap_text() function directly.
+

+
+ From Charles Crain:
+
+ - Fix a bug when BuildDir(duplicate=0) is used and SConscript
+ files are called from within other SConscript files.
+

+ registry.
+
+
+
+RELEASE 0.12 - Thu, 27 Mar 2003 23:52:09 -0600
+
+ From Charles Crain:
+
+ - Added support for the Perforce source code management system.
+
+ - Fix str(Node.FS) so that it returns a path relative to the calling
+ SConscript file's directory, not the top-level directory.
+
+ - Added support for a separate src_dir argument to SConscript()
+ that allows explicit specification of where the source files
+ for an SConscript file can be found.
+
+ - Support more easily re-usable flavors of command generators by
+ calling callable variables when strings are expanded.
+
+ From Steven Knight:
+
+ - Added an INSTALL construction variable that can be set to a function
+ to control how the Install() and InstallAs() Builders install files.
+ The default INSTALL function now copies, not links, files.
+
+ - Remove deprecated features: the "name" argument to Builder objects,
+ and the Environment.Update() method.
+
+ - Add an Environment.SourceCode() method to support fetching files
+ from source code systems. Add factory methods that create Builders
+ to support BitKeeper, CVS, RCS, and SCCS. Add support for fetching
+ files from RCS or SCCS transparently (like GNU Make).
+
+ - Make the internal to_String() function more efficient.
+
+ - Make the error message the same as other build errors when there's a
+ problem unlinking a target file in preparation for it being built.
+
+ - Make TARGET, TARGETS, SOURCE and SOURCES reserved variable names and
+ warn if the user tries to set them in a construction environment.
+
+ - Add support for Tar and Zip files.

+ subsidiary SConscript file. Fix documentation bugs in a tools
+ example, places that still assumed SCons split strings on white
+ space, and typos.
+
+ - Support fetching arbitrary files from the TARGETS or SOURCES lists
+ (e.g. ${SOURCES[2]}) when calculating the build signature of a
+ command.
+
+ - Don't silently swallow exceptions thrown by Scanners (or other
+ exceptions while finding a node's dependent children).
+
+ - Push files to CacheDir() before calling the superclass built()
+ method (which may clear the build signature as part of clearing
+ cached implicit dependencies, if the file has a source scanner).
+ (Bug reported by Jeff Petkau.)
+
+ - Raise an internal error if we attempt to push a file to CacheDir()
+ with a build signature of None.
+
+ - Add an explicit Exit() function for terminating early.
+
+ - Change the documentation to correctly describe that the -f option
+ doesn't change to the directory in which the specified file lives.
+
+ - Support changing directories locally with SConscript directory
+ path names relative to any SConstruct file specified with -f.
+ This allows you to build in another directory by simply changing
+ there and pointing at the SConstruct file in another directory.
+
+ - Change the default SConscriptChdir() behavior to change to the
+ SConscript directory while it's being read.
+
+ - Fix an exception thrown when the -U option was used with no
+ Default() target specified.
+
+ - Fix -u so that it builds things in corresponding build directories
+ when used in a source directory.
+
+ From Lachlan O'Dea:
+
+ - Add SharedObject() support to the masm tool.
+
+ - Fix WhereIs() to return normalized paths.
+

+ to a temporary file and renaming.
+
+ From Anthony Roach:
+
+ - Fix incorrect dependency-cycle errors when an Aliased source doesn't
+ exist.

+
+ - Added new AddPreAction() and AddPostAction() functions that support
+ taking additional actions before or after building specific targets.
+
+ - Add support for the PharLap ETS tool chain.
+
+ From Steven Knight:
+
+ - Allow Python function Actions to specify a list of construction
+ variables that should be included in the Action's signature.
+
+ - Allow libraries in the LIBS variable to explicitly include the prefix

+ (Bug reported by Gary Ruben.)
+

+ - Support using env.Append() on BUILDERS (and other dictionaries).
+ (Bug reported by Bj=F6rn Bylander.)
+
+ - Setting the BUILDERS construction variable now properly clears
+ the previous Builder attributes from the construction Environment.
+ (Bug reported by Bj=F6rn Bylander.)
+
+ - Fix adding a prefix to a file when the target isn't specified.
+ (Bug reported by Esa Ilari Vuokko.)
+
+ - Clean up error messages from problems duplicating into read-only
+ BuildDir directories or into read-only files.
+
+ - Add a CommandAction.strfunction() method, and add an "env" argument
+ to the FunctionAction.strfunction() method, so that all Action
+ objects have strfunction() methods, and the functions for building
+ and returning a string both take the same arguments.
+
+ - Add support for new CacheDir() functionality to share derived files
+ between builds, with related options --cache-disable, --cache-force,
+ and --cache-show.
+
+ - Change the default behavior when no targets are specified to build
+ everything in the current directory and below (like Make). This
+ can be disabled by specifying Default(None) in an SConscript.
+
+ - Revamp SCons installation to fix a case-sensitive installation
+ on Win32 systems, and to add SCons-specific --standard-lib,
+ --standalone-lib, and --version-lib options for easier user
+ control of where the libraries get installed.
+
+ - Fix the ability to directly import and use Platform and Tool modules
+ that have been implicitly imported into an Environment().
+
+ - Add support for allowing an embedding interface to annotate a node
+ when it's created.
+
+ - Extend the SConscript() function to accept build_dir and duplicate
+ keyword arguments that function like a BuildDir() call.
+
+ From Steve Leblanc:
+
+ - Fix the output of -c -n when directories are involved, so it
+ matches -c.
+
+ From Anthony Roach:
+
+ - Use a different shared object suffix (.os) when using gcc so shared
+ and static objects can exist side-by-side in the same directory.
+
+ - Allow the same object files on Win32 to be linked into either
+ shared or static libraries.
+
+ - Cache implicit cache values when using --implicit-cache.

+ what would have happened when the -n option is used.
+
+ - Don't create duplicate source files in a BuildDir when the -n
+ option is used.
+
+ - Refactor the Scanner interface to eliminate unnecessary Scanner
+ calls and make it easier to write efficient scanners.
+
+ - Added a "recursive" flag to Scanner creation that specifies the

+ by the scanner.
+
+ - Significant performance improvement from using a more efficient
+ check, throughout the code, for whether a Node has a Builder.
+
+ - Fix specifying only the source file to MultiStepBuilders such as

+
+ - Fix an exception when building from a file with the same basename as
+ the subdirectory in which it lives. (Bug reported by Gerard Patel.)
+
+ - Fix automatic deduction of a target file name when there are
+ multiple source files specified; the target is now deduced from just
+ the first source file in the list.
+
+ - Documentation fixes: better initial explanation of SConscript files;
+ fix a misformatted "table" in the StaticObject explanation.
+
+ From Steven Knight and Steve Leblanc:
+
+ - Fix the -c option so it will remove symlinks.
+
+ From Steve Leblanc:
+
+ - Add a Clean() method to support removing user-specified targets
+ when using the -c option.

+ data structure.
+
+ - Error message cleanups: Made consistent the format of error
+ messages (now all start with "scons: ***") and warning messages (now

+ not know how to build" error message.
+
+ - Added support for the MinGW tool chain.
+
+ - Added a --debug=includes option.

+
+ - Suport the Intel Fortran Compiler (ifl.exe).
+
+ - Supply an error message if there are no command-line or

+ when using the -U option.
+
+ - Issue a warning when -c can't remove a target.
+
+ - Eliminate unnecessary Scanner calls by checking for the
+ existence of a file before scanning it. (This adds a generic
+ hook to check an arbitrary condition before scanning.)
+
+ - Add explicit messages to tell when we're "Reading SConscript files
+ ...," "done reading SConscript files," "Building targets," and
+ "done building targets." Add a -Q option to supress these.
+
+ - Add separate $SHOBJPREFIX and $SHOBJSUFFIX construction variables
+ (by default, the same as $OBJPREFIX and $OBJSUFFIX).
+
+ - Add Make-like error messages when asked to build a source file,
+ and before trying to build a file that doesn't have all its source
+ files (including when an invalid drive letter is used on WIN32).
+

+
+ - Added a warnings framework and a --warn option to enable or
+ disable warnings.
+
+ - Make the C scanner warn users if files referenced by #include
+ directives cannot be found and --warn=dependency is specified.
+
+ - The BUILDERS construction variable should now be a dictionary
+ that maps builder names to actions. Existing uses of lists,
+ and the Builder name= keyword argument, generate warnings
+ about use of deprecated features.
+
+ - Removed the "shared" keyword argument from the Object and
+ Library builders.
+
+ - Added separated StaticObject, SharedObject, StaticLibrary and
+ SharedLibrary builders. Made Object and Library synonyms for

+
+ - Removed support for the prefix, suffix and src_suffix arguments
+ to Builder() to be callable functions.

+ - Add $CPPFLAGS to the shared-object command lines for g++ and gcc.
+
+ From Charles Crain and Steven Knight:
+
+ - Add a "tools=" keyword argument to Environment instantiation,
+ and a separate Tools() method, for more flexible specification
+ of tool-specific environment changes.
+
+ From Steven Knight:
+
+ - Add a "platform=" keyword argument to Environment instantiation,
+ and a separate Platform() method, for more flexible specification
+ of platform-specific environment changes.
+
+ - Updated README instructions and setup.py code to catch an
+ installation failure from not having distutils installed.
+
+ - Add descriptions to the -H help text for -D, -u and -U so
+ people can tell them apart.
+
+ - Remove the old feature of automatically splitting strings
+ of file names on white space.
+
+ - Add a dependency Scanner for native Fortran "include" statements,
+ using a new "F77PATH" construction variable.
+
+ - Fix C #include scanning to detect file names with characters like
+ '-' in them.
+
+ - Add more specific version / build output to the -v option.
+
+ - Add support for the GNU as, Microsoft masm, and nasm assemblers.
+
+ - Allow the "target" argument to a Builder call to be omitted, in

+ Builder's specified suffix.
+
+ - Add a tar archive builder.
+
+ - Add preliminary support for the OS/2 Platform, including the icc
+ and ilink Tools.
+
+ From Jeff Petkau:
+
+ - Fix --implicit-cache if the scanner returns an empty list.
+
+ From Anthony Roach:
+
+ - Add a "multi" keyword argument to Builder creation that specifies
+ it's okay to call the builder multiple times for a target.
+
+ - Set a "multi" on Aliases so multiple calls will append to an Alias.
+
+ - Fix emitter functions' use of path names when using BuildDir or
+ in subdirectories.
+
+ - Fix --implicit-cache causing redundant rebuilds when the header
+ file list changed.
+
+ - Fix --implicit-cache when a file has no implicit dependencies and
+ its source is generated.
+
+ - Make the drive letters on Windows always be the same case, so that
+ changes in the case of drive letters don't cause a rebuild.
+
+ - Fall back to importing the SCons.TimeStamp module if the SCons.MD5
+ module can't be imported.
+
+ - Fix interrupt handling to guarantee that a single interrupt will
+ halt SCons both when using -j and not.
+
+ - Fix .sconsign signature storage so that output files of one build
+ can be safely used as input files to another build.
+
+ - Added a --debug=time option to print SCons execution times.
+
+ - Print an error message if a file can't be unlinked before being
+ built, rather than just silently terminating the build.
+
+ - Add a SideEffect() method that can be used to tell the build
+ engine that a given file is created as a side effect of building
+ a target. A file can be specified as a side effect of more than
+ one build comand, in which case the commands will not be executed
+ simultaneously.
+
+ - Significant performance gains from not using our own version of
+ the inefficient stock os.path.splitext() method, caching source
+ suffix computation, code cleanup in MultiStepBuilder.__call__(),
+ and replicating some logic in scons_subst().
+
+ - Add --implicit-deps-changed and --implicit-deps-unchanged options.
+
+ - Add a GetLaunchDir() function.

+ - Add a SetBuildSignatureType() function.
+
+ From Zed Shaw:

+
+ From Charles Crain:
+

+
+ - Builders can now take arbitrary keyword arguments to create
+ attributes to be passed to: command generator functions,
+ FunctionAction functions, Builder emitter functions (below),
+ and prefix/suffix generator functions (below).
+
+ - Command generator functions can now return ANYTHING that can be
+ converted into an Action (a function, a string, a CommandGenerator
+ instance, even an ActionBase instance).
+
+ - Actions now call get_contents() with the actual target and source
+ nodes used for the build.
+
+ - A new DictCmdGenerator class replaces CompositeBuilder to support
+ more flexible Builder behavior internally.
+
+ - Builders can now take an emitter= keyword argument. An emitter
+ is a function that takes target, source, and env argument, then
+ return a 2-tuple of (new sources, new targets). The emitter is
+ called when the Builder is __call__'ed, allowing a user to modify
+ source and target lists.
+
+ - The prefix, suffix and src_suffix Builder arguments now take a
+ callable as well a string. The callable is passed the Environment
+ and any extra Builder keyword arguments and is expected to return
+ the appropriate prefix or suffix.
+
+ - CommandActions can now be a string, a list of command + argument
+ strings, or a list of commands (strings or lists).
+
+ - Added shared library support. The Object and Library Builders now
+ take a "shared=1" keyword argument to specify that a shared object
+ or shared library should be built. It is an error to try to build
+ static objects into a shared library or vice versa.
+
+ - Win32 support for .def files has been added. Added the Win32-specific
+ construction variables $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
+ $WIN32DLLPREFIX and $WIN32IMPLIBPREFIX. When building a .dll,
+ the new construction variable $WIN32_INSERT_DEF, controls whether
+ the appropriately-named .def file is inserted into the target
+ list (if not already present). A .lib file is always added to
+ a Library build if not present in the list of targets.
+
+ - ListBuilder now passes all targets to the action, not just the first.
+
+ - Fix so that -c now deletes generated yacc .h files.
+
+ - Builder actions and emitter functions can now be initialized, through
+ construction variables, to things other than strings.
+
+ - Make top-relative '#/dir' lookups work like '#dir'.
+
+ - Fix for relative CPPPATH directories in subsidiary SConscript files
+ (broken in 0.06).
+
+ - Add a for_signature argument to command generators, so that
+ generators that need to can return distinct values for the
+ command signature and for executing the command.
+
+ From Alex Jacques:
+
+ - Create a better scons.bat file from a py2bat.py script on the Python
+ mailing list two years ago (modeled after pl2bat.pl).
+
+ From Steven Knight:
+
+ - Fix so that -c -n does *not* remove the targets!
+
+ - Man page: Add a hierarchical libraries + Program example.
+
+ - Support long MSVC linker command lines through a builder action
+ that writes to a temporary file and uses the magic MSVC "link @file"
+ argument syntax if the line is longer than 2K characters.
+
+ - Fix F77 command-line options on Win32 (use /Fo instead of -o).
+
+ - Use the same action to build from .c (lower case) and .C (upper
+ case) files on case-insensitive systems like Win32.
+
+ - Support building a PDF file directly from a TeX or LaTeX file
+ using pdftex or pdflatex.
+
+ - Add a -x option to runtest.py to specify the script being tested.
+ A -X option indicates it's an executable, not a script to feed
+ to the Python interpreter.
+
+ - Add a Split() function (identical to SCons.Util.argmunge()) for use
+ in the next release, when Builders will no longer automatically split
+ strings on white space.
+
+ From Steve Leblanc:
+
+ - Add the SConscriptChdir() method.
+
+ From Anthony Roach:
+
+ - Fix --debug=tree when used with directory targets.
+
+ - Significant internal restructuring of Scanners and Taskmaster.
+
+ - Added new --debug=dtree option.
+
+ - Fixes for --profile option.
+
+ - Performance improvement in construction variable substitution.
+
+ - Implemented caching of content signatures, plus added --max-drift
+ option to control caching.
+
+ - Implemented caching of dependency signatures, enabled by new
+ --implicit-cache option.
+
+ - Added abspath construction variable modifier.
+
+ - Added $SOURCE variable as a synonym for $SOURCES[0].
+
+ - Write out .sconsign files on error or interrupt so intermediate
+ build results are saved.
+
+ - Change the -U option to -D. Make a new -U that builds just the
+ targets from the local SConscript file.
+
+ - Fixed use of sys.path so Python modules can be imported from
+ the SConscript directory.
+
+ - Fix for using Aliases with the -u, -U and -D options.
+
+ - Fix so that Nodes can be passed to SConscript files.
+
+ From Moshe Zadka:
+
+ - Changes for official Debian packaging.
+
+
+

+ in ARCOM if there's a "ranlib" program on the system.
+
+ - Add a configurable CFILESUFFIX for the Builder of .l and .y files
+ into C files.
+
+ - Add a CXXFile Builder that turns .ll and .yy files into .cc files
+ (configurable via a CXXFILESUFFIX construction variable).
+
+ - Use the POSIX-standard lex -t flag, not the GNU-specific -o flag.
+ (Bug reported by Russell Christensen.)
+
+ - Fixed an exception when CPPPATH or LIBPATH is a null string.
+ (Bug reported by Richard Kiss.)
+

+
+ - Add a WhereIs() method for searching for path names to executables.
+
+ - Add PDF and PostScript document builders.
+
+ - Add support for compiling Fortran programs from a variety of
+ suffixes (a la GNU Make): .f, .F, .for, .FOR, .fpp and .FPP
+
+ - Support a CPPFLAGS variable on all default commands that use the
+ C preprocessor.
+
+ From Steve Leblanc:
+
+ - Add support for the -U option.
+

+ separated strings.
+
+ - Add a document builder to create .dvi files from TeX (.tex) files.

+
+ - Man page: document Precious().
+
+
+
+RELEASE 0.05 - Thu, 21 Feb 2002 16:50:03 -0600
+
+ From Chad Austin:
+
+ - Set PROGSUFFIX to .exe under Cygwin.
+
+ From Charles Crain:
+
+ - Allow a library to specified as a command-line source file, not just
+ in the LIBS construction variable.
+
+ - Compensate for a bug in os.path.normpath() that returns '' for './'
+ on WIN32.
+
+ - More performance optimizations: cache #include lines from files,
+ eliminate unnecessary calls.
+
+ - If a prefix or suffix contains white space, treat the resulting
+ concatenation as separate arguments.
+
+ - Fix irregularities in the way we fetch DevStudio information from
+ the Windows registry, and in our registry error handling.
+
+ From Steven Knight:
+
+ - Flush stdout after print so it intermixes correctly with stderr
+ when redirected.
+
+ - Allow Scanners to return a list of strings, and document how to
+ write your own Scanners.
+
+ - Look up implicit (scanned) dependencies relative to the directory
+ of file being scanned.
+
+ - Make writing .sconsign files more robust by first trying to write
+ to a temp file that gets renamed.

+ to build any of the targets.
+
+ - WIN32 portability fixes in tests.
+
+ - Allow the list of variables exported to an SConscript file to be
+ a UserList, too.
+
+ - Document the overlooked LIBPATH construction variable.
+ (Bug reported by Eicke Godehardt.)

+ (included files), not just direct dependencies.
+
+ - Put the man page in the Debian distribution.
+
+ - Run HTML docs through tidy to clean up the HTML (for Konqueror).
+
+ - Add preliminary support for Unicode strings.

+
+
+
+RELEASE 0.04 - Wed, 30 Jan 2002 11:09:42 -0600
+
+ From Charles Crain:
+
+ - Significant performance improvements in the Node.FS and
+ Scanner subsystems.
+
+ - Fix signatures of binary files on Win32 systems.
+
+ - Allow LIBS and LIBPATH to be strings, not just arrays.
+
+ - Print a traceback if a Python-function builder throws an exception.
+
+ From Steven Knight:
+
+ - Fix using a directory as a Default(), and allow Default() to
+ support white space in file names for strings in arrays.
+
+ - Man page updates: corrected some mistakes, documented various
+ missing Environment methods, alphabetized the construction
+ variables and other functions, defined begin and end macros for
+ the example sections, regularized white space separation, fixed
+ the use of Export() in the Multiple Variants example.
+
+ - Function action fixes: None is now a successful return value.

+ files can use them too.
+
+ - Removed the Wrapper class between Nodes and Walkers.
+
+ - Add examples using Library, LIBS, and LIBPATH.
+
+ - The C Scanner now always returns a sorted list of dependencies
+ so order changes don't cause unnecessary rebuilds.

+
+ - Add the Ignore() method to ignore dependencies.
+
+ - Provide an error message when a nonexistent target is specified
+ on the command line.
+
+ - Remove targets before building them, and add an Environment

+
+ - Eliminate redundant calls to the same builder when the target is a
+ list of targets: Add a ListBuilder class that wraps Builders to
+ handle lists atomically. Extend the Task class to support building
+ and updating multiple targets in a single Task. Simplify the
+ interface between Task and Taskmaster.

+
+ - Add var=value command-line arguments.
+

+
+ - Performance improvements in the Node.FS and Sig.Calculator classes.
+
+ - Add the InstallAs() method.
+
+ - Execute commands through an external interpreter (sh, cmd.exe, or
+ command.com) to handle redirection metacharacters.
+
+ - Allow the user to supply a command handler.
+
+ From Steven Knight:
+
+ - Search both /usr/lib and /usr/local/lib for scons directories by
+ adding them both to sys.path, with whichever is in sys.prefix first.
+
+ - Fix interpreting strings of multiple white-space separated file names
+ as separate file names, allowing prefixes and suffixes to be appended
+ to each individually.
+
+ - Refactor to move CompositeBuilder initialization logic from the
+ factory wrapper to the __init__() method, and allow a Builder to
+ have both an action and a src_builder (or array of them).
+
+ - Refactor BuilderBase.__call__() to separate Node creation/lookup
+ from initialization of the Node's builder information.
+
+ - Add a CFile Builder object that supports turning lex (.l) and
+ yacc (.y) files into .c files.
+
+ - Document: variable interpretation attributes; how to propogate
+ the user's environment variables to executed commands; how to
+ build variants in multiple BuildDirs.
+
+ - Collect String, Dict, and List type-checking in common utility
+ routines so we can accept User{String,Dict,List}s all over.
+
+ - Put the Action factory and classes into their own module.
+
+ - Use one CPlusPlusAction in the Object Builder's action dictionary,
+ instead of letting it create multiple identical instances.
+
+ - Document the Install() and InstallAs() methods.
+
+ From Steve Leblanc:
+
+ - Require that a Builder be given a name argument, supplying a
+ useful error message when it isn't.
+
+ From Anthony Roach:
+
+ - Add a "duplicate" keyword argument to BuildDir() that can be set
+ to prevent linking/copying source files into build directories.
+
+ - Add a "--debug=tree" option to print an ASCII dependency tree.
+
+ - Fetch the location of the Microsoft Visual C++ compiler(s) from
+ the Registry, instead of hard-coding the location.
+
+ - Made Scanner objects take Nodes, not path names.
+
+ - Have the C Scanner cache the #include file names instead of
+ (re-)scanning the file each time it's called.
+
+ - Created a separate class for parent "nodes" of file system roots,
+ eliminating the need for separate is-parent-null checks everywhere.
+
+ - Removed defined __hash__() and __cmp() methods from FS.Entry, in
+ favor of Python's more efficient built-in identity comparisons.
