217 RELEASE 0.98.2 - Sun, 20 Apr 2008 23:38:56 -0700
221 - Fix a bug in Fortran suffix computation that would cause SCons to
222 run out of memory on Windows systems.

249 - Fix the ability to use LoadableModule() under MinGW.
251 From David Cournapeau:
253 - Various missing Fortran-related construction variables have been added.
255 - SCons now uses the program specified in the $FORTRAN construction
256 variable to link Fortran object files.
258 - Fortran compilers on Linux (Intel, g77 and gfortran) now add the -fPIC
259 option by default when compilling shared objects.
261 - New 'sunf77', 'sunf90' and 'sunf95' Tool modules have been added to
262 support Sun Fortran compilers. On Solaris, the Sun Fortran compilers
263 are used in preference to other compilers by default.
265 - Fortran support now uses gfortran in preference to g77.
267 - Fortran file suffixes are now configurable through the
268 $F77FILESUFFIXES, $F90FILESUFFIXES, $F95FILESUFFIXES and
269 $FORTRANFILESUFFIXES variables.
273 - Make the -d, -e, -w and --no-print-directory options "Ignored for
274 compatibility." (We're not going to implement them.)
276 - Fix a serious inefficiency in how SCons checks for whether any source
277 files are missing when a Builder call creates many targets from many
280 - In Java projects, make the target .class files depend only on the
281 specific source .java files where the individual classes are defined.
283 - Don't store duplicate source file entries in the .sconsign file so
284 we don't endlessly rebuild the target(s) for no reason.
286 - Add a Variables object as the first step towards deprecating the
287 Options object name. Similarly, add BoolVariable(), EnumVariable(),
288 ListVariable(), PackageVariable() and PathVariable() functions
289 as first steps towards replacing BoolOption(), EnumOption(),
290 ListOption(), PackageOption() and PathOption().
292 - Change the options= keyword argument to the Environment() function
293 to variables=, to avoid confusion with SCons command-line options.
294 Continue supporting the options= keyword for backwards compatibility.
296 - When $SWIGFLAGS contains the -python flag, expect the generated .py
297 file to be in the same (sub)directory as the target.
299 - When compiling C++ files, allow $CCFLAGS settings to show up on the
300 command line even when $CXXFLAGS has been redefined.
302 - Fix --interactive with -u/-U/-D when a VariantDir() is used.
304 From Anatoly Techtonik:
306 - Have the scons.bat file add the script execution directory to its
307 local %PATH% on Windows, so the Python executable can be found.
311 - Fix passing variable names as a list to the Return() function.
315 - Add support for the GDC 'D' language compiler.
319 RELEASE 0.98 - Sun, 30 Mar 2008 23:33:05 -0700
323 - Fix the --keep-going flag so it builds all possible targets even when
324 a later top-level target depends on a child that failed its build.
326 - Fix being able to use $PDB and $WINDWOWS_INSERT_MANIFEST together.
328 - Don't crash if un-installing the Intel C compiler leaves left-over,
329 dangling entries in the Windows registry.
331 - Improve support for non-standard library prefixes and suffixes by
332 stripping all prefixes/suffixes from file name string as appropriate.
334 - Reduce the default stack size for -j worker threads to 256 Kbytes.
335 Provide user control over this value by adding --stack-size and
336 --warn=stack-size options, and a SetOption('stack_size') function.
338 - Fix a crash on Linux systems when trying to use the Intel C compiler
339 and no /opt/intel_cc_* directories are found.
341 - Improve using Python functions as actions by incorporating into
342 a FunctionAction's signature:
343 - literal values referenced by the byte code.
344 - values of default arguments
345 - code of nested functions
346 - values of variables captured by closures
347 - names of referenced global variables and functions
349 - Fix the closing message when --clean and --keep-going are both
350 used and no errors occur.
352 - Add support for the Intel C compiler on Mac OS X.
354 - Speed up reading SConscript files by about 20% (for some
355 configurations) by: 1) optimizing the SCons.Util.is_*() and
356 SCons.Util.flatten() functions; 2) avoiding unnecessary os.stat()
357 calls by using a File's .suffix attribute directly instead of
362 - Have the D language scanner search for .di files as well as .d files.
364 - Add a find_include_names() method to the Scanner.Classic class to
365 abstract out how included names can be generated by subclasses.
367 - Allow the D language scanner to detect multiple modules imported by
370 From Konstantin Bozhikov:
372 - Support expansion of construction variables that contain or refer
373 to lists of other variables or Nodes within expansions like $CPPPATH.
375 - Change variable substitution (the env.subst() method) so that an
376 input sequence (list or tuple) is preserved as a list in the output.
378 From David Cournapeau:
380 - Add a CheckDeclaration() call to configure contexts.
382 - Improve the CheckTypeSize() code.
384 - Add a Define() call to configure contexts, to add arbitrary #define
385 lines to a generated configure header file.
387 - Add a "gfortran" Tool module for the GNU F95/F2003 compiler.
389 - Avoid use of -rpath with the Mac OS X linker.
391 - Add comment lines to the generated config.h file to describe what
392 the various #define/#undef lines are doing.
396 - Support the ability to subclass the new-style "str" class as input
399 - Improve the performance of our type-checking by using isinstance()
400 with new-style classes.
402 - Fix #include (and other $*PATH variables searches) of files with
403 absolute path names. Don't die if they don't exist (due to being
404 #ifdef'ed out or the like).
406 - Fix --interactive mode when Default(None) is used.
408 - Fix --debug=memoizer to work around a bug in base Python 2.2 metaclass
409 initialization (by just not allowing Memoization in Python versions
412 - Have the "scons-time time" subcommand handle empty log files, and
413 log files that contain no results specified by the --which option.
415 - Fix the max Y of vertical bars drawn by "scons-time --fmt=gnuplot".
417 - On Mac OS X, account for the fact that the header file generated
418 from a C++ file will be named (e.g.) file.cpp.h, not file.hpp.
420 - Fix floating-point numbers confusing the Java parser about
421 generated .class file names in some configurations.
423 - Document (nearly) all the values you can now fetch with GetOption().
425 - Fix use of file names containing strings of multiple spaces when
426 using ActionFactory instances like the Copy() or Move() function.
428 - Fix a 0.97 regression when using a variable expansion (like
429 $OBJSUFFIX) in a source file name to a builder with attached source
430 builders that match suffix (like Program()+Object()).
432 - Have the Java parser recognize generics (surrounded by angle brackets)
433 so they don't interfere with identifying anonymous inner classes.
435 - Avoid an infinite loop when trying to use saved copies of the
436 env.Install() or env.InstallAs() after replacing the method
439 - Improve the performance of setting construction variables.
441 - When cloning a construction environment, avoid over-writing an
442 attribute for an added method if the user explicitly replaced it.
444 - Add a warning about deprecated support for Python 1.5, 2.0 and 2.1.
446 - Fix being able to SetOption('warn', ...) in SConscript files.
448 - Add a warning about env.Copy() being deprecated.
450 - Add warnings about the --debug={dtree,stree,tree} options
453 - Add VariantDir() as the first step towards deprecating BuildDir().
454 Add the keyword argument "variant_dir" as the replacement for
457 - Add warnings about the {Target,Source}Signatures() methods and
458 functions being deprecated.
462 - Enhance TeX and LaTeX support to work with BuildDir(duplicate=0).
464 - Re-run LaTeX when it issues a package warning that it must be re-run.
466 From Leanid Nazdrynau:
468 - Have the Copy() action factory preserve file modes and times
469 when copying individual files.
473 - If $JARCHDIR isn't set explicitly, use the .java_classdir attribute
474 that was set when the Java() Builder built the .class files.
478 - Document the Dir(), File() and Entry() methods of Dir and File Nodes.
480 - Add the parse_flags option when creating Environments
482 From Gary Oberbrunner:
484 - Make File(), Dir() and Entry() return a list of Nodes when passed
485 a list of names, instead of trying to make a string from the name
486 list and making a Node from that string.
488 - Fix the ability to build an Alias in --interactive mode.
490 - Fix the ability to hash the contents of actions for nested Python
491 functions on Python versions where the inability to pickle them
492 returns a TypeError (instead of the documented PicklingError).
496 - Fix use of the Intel C compiler when the top compiler directory,
497 but not the compiler version, is specified.
499 - Handle Intel C compiler network license files (port@system).
503 - Fix how Python Value Nodes are printed in --debug=explain output.
507 - Add a --interactive option that starts a session for building (or
508 cleaning) targets without re-reading the SConscript files every time.
510 - Fix use of readline command-line editing in --interactive mode.
512 - Have the --interactive mode "build" command with no arguments
513 build the specified Default() targets.

521 versions where all() is a builtin function.
523 From Daniel Svensson:
525 - Code correction in SCons.Util.is_List().
529 - Support the SWIG %module statement with following modifiers in
530 parenthese (e.g., '%module(directors="1")').
534 RELEASE 0.97.0d20071212 - Wed, 12 Dec 2007 09:29:32 -0600
538 - Fix occasional spurious rebuilds and inefficiency when using
539 --implicit-cache and Builders that produce multiple targets.
541 - Allow SCons to not have to know about the builders of generated
542 files when BuildDir(duplicate=0) is used, potentially allowing some
543 SConscript files to be ignored for smaller builds.
545 From David Cournapeau:
547 - Add a CheckTypeSize() call to configure contexts.
551 - Make the "contents" of Alias Nodes a concatenation of the children's
552 content signatures (MD5 checksums), not a concatenation of the
553 children's contents, to avoid using large amounts of memory during
554 signature calculation.
558 - Fix a lot of typos in the man page and User's Guide.
560 From Geoffrey Irving:
562 - Speed up conversion of paths in .sconsign files to File or Dir Nodes.
566 - Add an Options.UnknownOptions() method that returns any settings
567 (from the command line, or whatever dictionary was passed in)
568 that aren't known to the Options object.
570 - Add a Glob() function.
572 - When removing targets with the -c option, use the absolute path (to
573 avoid problems interpreting BuildDir() when the top-level directory
574 is the source directory).
576 - Fix problems with Install() and InstallAs() when called through a
577 clone (of a clone, ...) of a cloned construction environment.
579 - When executing a file containing Options() settings, add the file's
580 directory to sys.path (so modules can be imported from there) and
581 explicity set __name__ to the name of the file so the statement's
582 in the file can deduce the location if they need to.
584 - Fix an O(n^2) performance problem when adding sources to a target
585 through calls to a multi Builder (including Aliases).
587 - Redefine the $WINDOWSPROGMANIFESTSUFFIX and
588 $WINDOWSSHLIBMANIFESTSUFFIX variables so they pick up changes to
589 the underlying $SHLIBSUFFIX and $PROGSUFFIX variables.
591 - Add a GetBuildFailures() function that can be called from functions
592 registered with the Python atexit module to print summary information
593 about any failures encountered while building.
595 - Return a NodeList object, not a Python list, when a single_source
596 Builder like Object() is called with more than one file.
598 - When searching for implicit dependency files in the directories
599 in a $*PATH list, don't create Dir Nodes for directories that
600 don't actually exist on-disk.
602 - Add a Requires() function to allow the specification of order-only
603 prerequisites, which will be updated before specified "downstream"
604 targets but which don't actually cause the target to be rebuilt.
606 - Restore the FS.{Dir,File,Entry}.rel_path() method.
608 - Make the default behavior of {Source,Target}Signatures('timestamp')
609 be equivalent to 'timestamp-match', not 'timestamp-newer'.
611 - Fix use of CacheDir with Decider('timestamp-newer') by updating
612 the modification time when copying files from the cache.
614 - Fix random issues with parallel (-j) builds on Windows when Python
615 holds open file handles (especially for SCons temporary files,
616 or targets built by Python function actions) across process creation.
618 From Maxim Kartashev:
620 - Fix test scripts when run on Solaris.
622 From Gary Oberbrunner:
624 - Fix Glob() when a pattern is in an explicitly-named subdirectory.

639 - Move the documentation of Install() and InstallAs() from the list
640 of functions to the list of Builders (now that they're implemented
643 - Allow env.CacheDir() to be set per construction environment. The
644 global CacheDir() function now sets an overridable global default.
646 - Add an env.Decider() method and a Node.Decider() method that allow
647 flexible specification of an arbitrary function to decide if a given
648 dependency has changed since the last time a target was built.
650 - Don't execute Configure actions (while reading SConscript files)
651 when cleaning (-c) or getting help (-h or -H).
653 - Add to each target an implicit dependency on the external command(s)
654 used to build the target, as found by searching env['ENV']['PATH']
655 for the first argument on each executed command line.
657 - Add support for a $IMPLICIT_COMMAND_DEPENDENCIES construction
658 variabe that can be used to disable the automatic implicit
659 dependency on executed commands.
661 - Add an "ensure_suffix" keyword to Builder() definitions that, when
662 true, will add the configured suffix to the targets even if it looks
663 like they already have a different suffix.
665 - Add a Progress() function that allows for calling a function or string
666 (or list of strings) to display progress while walking the DAG.
668 - Allow ParseConfig(), MergeFlags() and ParseFlags() to handle output
669 from a *config command with quoted path names that contain spaces.
671 - Make the Return() function stop processing the SConscript file and
672 return immediately. Add a "stop=" keyword argument that can be set
673 to False to preserve the old behavior.
675 - Fix use of exitstatfunc on an Action.
677 - Introduce all man page function examples with "Example:" or "Examples:".
679 - When a file gets added to a directory, make sure the directory gets
680 re-scanned for the new implicit dependency.
682 - Fix handling a file that's specified multiple times in a target
683 list so that it doesn't cause dependent Nodes to "disappear" from
684 the dependency graph walk.
688 - Avoid race conditions with same-named files and directory creation
689 when pushing copies of files to CacheDir().
693 - Handle $ in Java class names.
695 From Gary Oberbrunner:
697 - Add support for the Intel C compiler on Windows64.
699 - On SGI IRIX, have $SHCXX use $CXX by default (like other platforms).
703 - When Cloning a construction environment, set any variables before
704 applying tools (so the tool module can access the configured settings)
705 and re-set them after (so they end up matching what the user set).
707 From Matthias Troffaes:
709 - Make sure extra auxiliary files generated by some LaTeX packages
710 and not ending in .aux also get deleted by scons -c.
714 - Add a $JAVABOOTCLASSPATH variable for directories to be passed to the
715 javac -bootclasspath option.
717 From Christoph Wiedemann:
719 - Add implicit dependencies on the commands used to build a target.
724 RELEASE 0.97.0d20070809 - Fri, 10 Aug 2007 10:51:27 -0500
726 From Lars Albertsson:
728 - Don't error if a #include line happens to match a directory
729 somewhere on a path (like $CPPPATH, $FORTRANPATH, etc.).
733 - Fix listing multiple projects in Visual Studio 7.[01] solution files,
734 including generating individual project GUIDs instead of re-using
739 - Add /opt/SUNWspro/bin to the default execution PATH on Solaris.
743 - Only expect the Microsoft IDL compiler to emit *_p.c and *_data.c
744 files if the /proxy and /dlldata switches are used (respectively).
748 - Have --debug=explain report if a target is being rebuilt because
749 AlwaysBuild() is specified (instead of "unknown reasons").
751 - Support {Get,Set}Option('help') to make it easier for SConscript
752 files to tell if a help option (-h, --help, etc.) has been specified.
754 - Support {Get,Set}Option('random') so random-dependency interaction
755 with CacheDir() is controllable from SConscript files.
757 - Add a new AddOption() function to support user-defined command-
758 line flags (like --prefix=, --force, etc.).
760 - Push and retrieve built symlinks to/from a CacheDir() as actual
761 symlinks, not by copying the file contents.
763 - Fix how the Action module handles stringifying the shared library
764 generator in the Tool/mingw.py module.
766 - When generating a config.h file, print "#define HAVE_{FEATURE} 1"
767 instad of just "#define HAVE_{FEATURE}", for more compatibility
768 with Autoconf-style projects.
770 - Fix expansion of $TARGET, $TARGETS, $SOURCE and $SOURCES keywords in
771 Visual C/C++ PDB file names.
773 - Fix locating Visual C/C++ PDB files in build directories.
775 - Support an env.AddMethod() method and an AddMethod() global function
776 for adding a new method, respectively, to a construction environment
777 or an arbitrary object (such as a class).
779 - Fix the --debug=time option when the -j option is specified and all
780 files are up to date.
782 - Add a $SWIGOUTDIR variable to allow setting the swig -outdir option,
783 and use it to identify files created by the swig -java option.
785 - Add a $SWIGPATH variable that specifies the path to be searched
786 for included SWIG files, Also add related $SWIGINCPREFIX and
787 $SWIGINCSUFFIX variables that specify the prefix and suffix to
788 be be added to each $SWIGPATH directory when expanded on the SWIG
791 - More efficient copying of construction environments (mostly borrowed
792 from copy.deepcopy() in the standard Python library).
794 - When printing --tree=prune output, don't print [brackets] around
795 source files, only do so for built targets with children.
797 - Fix interpretation of Builder source arguments when the Builder has
798 a src_suffix *and* a source_builder and the argument has no suffix.
800 - Fix use of expansions like ${TARGET.dir} or ${SOURCE.dir} in the
801 following construction variables: $FORTRANMODDIR, $JARCHDIR,
802 $JARFLAGS, $LEXFLAGS, $SWIGFLAGS, $SWIGOUTDIR and $YACCFLAGS.
804 - Fix dependencies on Java files generated by SWIG so they can be
805 detected and built in one pass.
807 - Fix SWIG when used with a BuildDir().
809 From Leanid Nazdrynau:
811 - When applying Tool modules after a construction environment has
812 already been created, don't overwrite existing $CFILESUFFIX and
813 $CXXFILESUFFIX value.
815 - Support passing the Java() builder a list of explicit .java files
816 (not only a list of directories to be scanned for .java files).
818 - Support passing .java files to the Jar() and JavaH() builders, which
819 then use the builder underlying the Java() builder to turn them into
820 .class files. (That is, the Jar()-Java() chain of builders become
821 multi-step, like the Program()-Object()-CFile() builders.)
823 - Support passing SWIG .i files to the Java builders (Java(),
824 Jar(), JavaH()), to cause intermediate .java files to be created
827 - Add $JAVACLASSPATH and $JAVASOURCEPATH variables, that get added to
828 the javac "-classpath" and "-sourcepath" options. (Note that SCons
829 does *not* currently search these paths for implicit dependencies.)
831 - Commonize initialization of Java-related builders.
835 - Find Java anonymous classes when the next token after the name is
838 From Gary Oberbrunner:
840 - Fix a code example in the man page.
844 - Add support for the file names that Java 1.5 (and 1.6) generates for
845 nested anonymous inner classes, which are different from Java 1.4.
849 - Allow worker threads to terminate gracefully when all jobs are
854 - Add LaTeX scanner support for finding dependencies specified with
855 the \usepackage{} directive.
859 RELEASE 0.97 - Thu, 17 May 2007 08:59:41 -0500
863 - Fix a bug that would make parallel builds stop in their tracks if
864 Nodes that depended on lists that contained some Nodes built together
865 caused the reference count to drop below 0 if the Nodes were visited
866 and commands finished in the wrong order.
868 - Make sure the DirEntryScanner doesn't choke if it's handed something
869 that's not a directory (Node.FS.Dir) Node.
873 RELEASE 0.96.96 - Thu, 12 Apr 2007 12:36:25 -0500
875 NOTE: This is (Yet) a(nother) pre-release of 0.97 for testing purposes.
879 - Man page fix: remove cut-and-paste sentence in NoCache() description.
881 From Dmitry Grigorenko and Gary Oberbrunner:
883 - Use the Intel C++ compiler, not $CC, to link C++ source.
887 - Fix the man page example of propagating a user's external environment.
891 - Back out (most of) the Windows registry installer patch, which
892 seems to not work on some versions of Windows.
894 - Don't treat Java ".class" attributes as defining an inner class.
896 - Fix detecting an erroneous Java anonymous class when the first
897 non-skipped token after a "new" keyword is a closing brace.
899 - Fix a regression when a CPPDEFINES list contains a tuple, the second
900 item of which (the option value) is a construction variable expansion
901 (e.g. $VALUE) and the value of the variable isn't a string.
903 - Improve the error message if an IOError (like trying to read a
904 directory as a file) occurs while deciding if a node is up-to-date.
906 - Fix "maximum recursion" / "unhashable type" errors in $CPPPATH
907 PathList expansion if a subsidiary expansion yields a stringable,
910 - Generate API documentation from the docstrings (using epydoc).
912 - Fix use of --debug=presub with Actions for out-of-the-box Builders.
914 - Fix handling nested lists within $CPPPATH, $LIBPATH, etc.
916 - Fix a "builders_used" AttributeError that real-world Qt initialization
917 triggered in the refactored suffix handling for Builders.
919 - Make the reported --debug=time timings meaningful when used with -j.
920 Better documentation of what the times mean.
922 - User Guide updates: --random, AlwaysBuild(), --tree=,
923 --debug=findlibs, --debug=presub, --debug=stacktrace,
926 - Document (in both man page and User's Guide) that --implicit-cache
927 ignores changes in $CPPPATH, $LIBPATH, etc.
929 From Jean-Baptiste Lab:
931 - Remove hard-coded dependency on Python 2.2 from Debian packaging files.
935 - Handle spaces in the build target name in Visual Studio project files.
939 - Re-run LaTeX after BibTeX has been re-run in response to a changed
944 - Make additional TeX auxiliary files (.toc, .idx and .bbl files)
945 Precious so their removal doesn't affect whether the necessary
946 sections are included in output PDF or PostScript files.
948 From Gary Oberbrunner:
950 - Fix the ability to import modules in the site_scons directory from
955 - Make sure parallel (-j) builds all targets even if they show up
956 multiple times in the child list (as a source and a dependency).
958 From Matthias Troffaes:
960 - Don't re-run TeX if the triggering strings (\makeindex, \bibliography
961 \tableofcontents) are commented out.
965 - Fix use of custom include and lib paths with Visual Studio 8.
967 - Select the default .NET Framework SDK Dir based on the version of
968 Visual Studio being used.
972 RELEASE 0.96.95 - Mon, 12 Feb 2007 20:25:16 -0600
976 - Add the scons.org URL and a package description to the setup.py
979 - Have the Windows installer add a registry entry for scons.bat in the
980 "App Paths" key, so scons.bat can be executed without adding the
981 directory to the %PATH%. (Python itself works this way.)
985 - Fix looking for default paths in Visual Studio 8.0 (and later).
987 - Add -lm to the list of default D libraries for linking.
991 - Provide a more complete write-your-own-Scanner example in the man page.
993 From Ralf W. Grosse-Kunstleve:
995 - Contributed upstream Python change to our copied subprocess.py module
996 for more efficient standard input processing.
1000 - Fix the Node.FS.Base.rel_path() method when the two nodes are on
1001 different drive letters. (This caused an infinite loop when
1002 trying to write .sconsign files.)
1004 - Fully support Scanners that use a dictionary to map file suffixes
1007 - Support delayed evaluation of the $SPAWN variable to allow selection
1008 of a function via ${} string expansions.
1010 - Add --srcdir as a synonym for -Y/--repository.
1012 - Document limitations of #include "file.h" with Repository().
1014 - Fix use of a toolpath under the source directory of a BuildDir().
1016 - Fix env.Install() with a file name portion that begins with '#'.
1018 - Fix ParseConfig()'s handling of multiple options in a string that's
1019 replaced a *FLAGS construction variable.
1021 - Have the C++ tools initialize common C compilation variables ($CCFLAGS,
1022 $SHCCFLAGS and $_CCCOMCOM) even if the 'cc' Tool isn't loaded.
1024 From Leanid Nazdrynau:
1026 - Fix detection of Java anonymous classes if a newline precedes the
1029 From Gary Oberbrunner:
1031 - Document use of ${} to execute arbitrary Python code.
1034 1) automatically adding a site_scons subdirectory (in the top-level
1035 SConstruct directory) to sys.path (PYTHONPATH);
1036 2) automatically importing site_scons/site_init.py;
1037 3) automatically adding site_scons/site_tools to the toolpath.
1041 - Change ParseConfig() to preserve white space in arguments passed in
1046 - Fix adding explicitly-named Java inner class files (and any
1047 other file names that may contain a '$') to Jar files.
1051 - Add a NoCache() function to mark targets as unsuitable for propagating
1052 to (or retrieving from) a CacheDir().
1056 - If the swig -noproxy option is used, it won't generate a .py file,
1057 so don't emit it as a target that we expect to be built.
1061 RELEASE 0.96.94 - Sun, 07 Jan 2007 18:36:20 -0600
1063 NOTE: This is a pre-release of 0.97 for testing purposes.
1067 - Allow arbitrary white space after a SWIG %module declaration.
1071 - When compiling resources under MinGW, make sure there's a space
1072 between the --include-dir option and its argument.
1076 - Alleviate long command line issues on Windows by executing command
1077 lines directly via os.spawnv() if the command line doesn't need
1078 shell interpretation (has no pipes, redirection, etc.).
1080 From Walter Franzini:
1082 - Exclude additional Debian packaging files from the copyright check.
1086 - Handle the conflict between the impending Python 2.6 'as' keyword
1087 and our Tool/as.py module name.
1091 - Speed up the Node.FS.Dir.rel_path() method used to generate path names
1092 that get put into the .sconsign* file(s).
1094 - Optimize Node.FS.Base.get_suffix() by computing the suffix once, up
1095 front, when we set the Node's name. (Duh...)
1097 - Reduce the Memoizer's responsibilities to simply counting hits and
1098 misses when the --debug=memoizer option is used, not to actually
1099 handling the key calculation and memoization itself. This speeds
1100 up some configurations significantly, and should cause no functional
1103 - Add a new scons-time script with subcommands for generating
1104 consistent timing output from SCons configurations, extracting
1105 various information from those timings, and displaying them in
1108 - Reduce some unnecessary stat() calls from on-disk entry type checks.
1110 - Fix SideEffect() when used with -j, which was badly broken in 0.96.93.
1112 - Propagate TypeError exceptions when evaluating construction variable
1113 expansions up the stack, so users can see what's going on.
1115 - When disambiguating a Node.FS.Entry into a Dir or File, don't look
1116 in the on-disk source directory until we've confirmed there's no
1117 on-disk entry locally and there *is* one in the srcdir. This avoids
1118 creating a phantom Node that can interfere with dependencies on
1121 - Add an AllowSubstExceptions() function that gives the SConscript
1122 files control over what exceptions cause a string to expand to ''
1123 vs. terminating processing with an error.
1125 - Allow the f90.py and f95.py Tool modules to compile earlier source
1126 source files of earlier Fortran version.
1128 - Fix storing signatures of files retrieved from CacheDir() so they're
1129 correctly identified as up-to-date next invocation.
1131 - Make sure lists of computed source suffixes cached by Builder objects
1132 don't persist across changes to the list of source Builders (so the
1133 addition of suffixes like .ui by the qt.py Tool module take effect).
1135 - Enhance the bootstrap.py script to allow it to be used to execute
1136 SCons more easily from a checked-out source tree.
1140 - Fix post-Memoizer value caching misspellings in Node.FS._doLookup().
1142 From Rob Managan, Dmitry Mikhin and Joel B. Mohler:
1144 - Handle TeX/LaTeX files in subdirectories by changing directory
1145 before invoking TeX/LaTeX.
1147 - Scan LaTeX files for \bibliography lines.
1149 - Support multiple file names in a "\bibliography{file1,file2}" string.
1151 - Handle TeX warnings about undefined citations.
1153 - Support re-running LaTeX if necessary due to a Table of Contents.
1157 - Return LaTeX if "Rerun to get citations correct" shows up on the next
1158 line after the "Warning:" string.
1160 From Gary Oberbrunner:
1162 - Add #include lines to fix portability issues in two tests.
1164 - Eliminate some unnecessary os.path.normpath() calls.
1166 - Add a $CFLAGS variable for C-specific options, leaving $CCFLAGS
1167 for options common to C and C++.
1171 - Have the error message print the missing file that Qt can't find.
1175 - Fix env.MergeFlags() appending to construction variable value of None.
1179 - Fix the "sconsign" script when the .sconsign.dblite file is explicitly
1180 specified on the command line (and not intuited from the old way of
1181 calling it with just ".sconsign").
1183 From Jose Pablo Ezequiel "Pupeno" Fernandez Silva:
1185 - Give the 'lex' tool knowledge of the additional target files produced
1186 by the flex "--header-file=" and "--tables-file=" options.
1188 - Give the 'yacc' tool knowledge of the additional target files produced
1189 by the bison "-g", "--defines=" and "--graph=" options.
1191 - Generate intermediate files with Objective C file suffixes (.m) when
1192 the lex and yacc source files have appropriate suffixes (.lm and .ym).
1196 - Have the mslink.py Tool only look for a 'link' executable on Windows
1199 From Vaclav Smilauer:
1201 - Add support for a "srcdir" keyword argument when calling a Builder,
1202 which will add a srcdir prefix to all non-relative string sources.
1204 From Jonathan Ultis:
1206 - Allow Options converters to take the construction environment as
1207 an optional argument.
1211 RELEASE 0.96.93 - Mon, 06 Nov 2006 00:44:11 -0600
1213 NOTE: This is a pre-release of 0.97 for testing purposes.
1217 - Allow Python Value Nodes to be Builder targets.
1221 - Only filter Visual Studio common filename prefixes on complete
1226 - Fix the build of the SCons documentation on systems that don't
1227 have "python" in the $PATH.
1231 - Enhance ParseConfig() to recognize options that begin with '+'.
1233 From John Calcote, Elliot Murphy:
1235 - Document ways to override the CCPDBFLAGS variable to use the
1236 Microsoft linker's /Zi option instead of the default /Z7.
1238 From Christopher Drexler:
1240 - Make SCons aware bibtex must be called if any \include files
1241 cause creation of a bibliography.
1243 - Make SCons aware that "\bilbiography" in TeX source files means
1244 that related .bbl and .blg bibliography files will be created.
1245 (NOTE: This still needs to search for the string in \include files.)
1249 - Fix inconsistent handling of Action strfunction arguments.
1251 - Preserve white space in display Action strfunction strings.
1253 From James Y. Knight and Gerard Patel:
1255 - Support creation of shared object files from assembly language.
1259 - Speed up the Taskmaster significantly by avoiding unnecessary
1260 re-scans of Nodes to find out if there's work to be done, having it
1261 track the currently-executed top-level target directly and not
1262 through its presence on the target list, and eliminating some other
1263 minor list(s), method(s) and manipulation.
1265 - Fix the expansion of $TARGET and $SOURCE in the expansion of
1266 $INSTALLSTR displayed for non-environment calls to InstallAs().
1268 - Fix the ability to have an Alias() call refer to a directory
1269 name that's not identified as a directory until later.
1271 - Enhance runtest.py with an option to use QMTest as the harness.
1272 This will become the default behavior as we add more functionality
1275 - Let linking on mingw use the default function that chooses $CC (gcc)
1276 or $CXX (g++) depending on whether there are any C++ source files.
1278 - Work around a bug in early versions of the Python 2.4 profile module
1279 that caused the --profile= option to fail.
1281 - Only call Options validators and converters once when initializing a
1282 construction environment.
1284 - Fix the ability of env.Append() and env.Prepend(), in all known Python
1285 versions, to handle different input value types when the construction
1286 variable being updated is a dictionary.
1288 - Add a --cache-debug option for information about what files it's
1289 looking for in a CacheDir().
1291 - Document the difference in construction variable expansion between
1292 {Action,Builder}() and env.{Action,Builder}().
1294 - Change the name of env.Copy() to env.Clone(), keeping the old name
1295 around for backwards compatibility (with the intention of eventually
1296 phasing it out to avoid confusion with the Copy() Action factory).
1300 - Support cleaning and scanning SWIG-generated files.
1304 - Allow selection of Visual Studio version by setting $MSVS_VERSION
1305 after construction environment initialization.
1307 From Jean-Baptiste Lab:
1309 - Try using zipimport if we can't import Tool or Platform modules
1310 using the normal "imp" module. This allows SCons to be packaged
1311 using py2exe's all-in-one-zip-file approach.
1315 - Do not re-scan files if the scanner returns no implicit dependencies.
1317 From Sanjoy Mahajan:
1319 - Change use of $SOURCES to $SOURCE in all TeX-related Tool modules.
1321 From Joel B. Mohler:
1323 - Make SCons aware that "\makeindex" in TeX source files means that
1324 related .ilg, .ind and .idx index files will be created.
1325 (NOTE: This still needs to search for the string in \include files.)
1327 - Prevent scanning the TeX .aux file for additional files from
1328 trying to remove it twice when the -c option is used.
1330 From Leanid Nazdrynau:
1332 - Give the MSVC RES (resource) Builder a src_builder list and a .rc
1333 src_suffix so other builders can generate .rc files.
1335 From Matthew A. Nicholson:
1337 - Enhance Install() and InstallAs() to handle directory trees as sources.
1341 - Don't use the -fPIC flag when using gcc on Windows (e.g. MinGW).
1345 - Add an env.ParseFlags() method that provides separate logic for
1346 parsing GNU tool chain flags into a dictionary.
1348 - Add an env.MergeFlags() method to apply an arbitrary dictionary
1349 of flags to a construction environment's variables.
1351 From Gary Oberbrunner:
1353 - Fix parsing tripartite Intel C compiler version numbers on Linux.
1355 - Extend the ParseConfig() function to recognize -arch and
1358 - Have the error message list the known suffixes when a Builder call
1359 can't build a source file with an unknown suffix.
1361 From Karol Pietrzak:
1363 - Avoid recursive calls to main() in the program snippet used by the
1364 SConf subsystem to test linking against libraries. This changes the
1365 default behavior of CheckLib() and CheckLibWithHeader() to print
1366 "Checking for C library foo..." instead of "Checking for main()
1367 in C library foo...".
1371 - Throw an exception if a command called by ParseConfig() or
1372 ParseFlags() returns an error.
1374 From Stefan Seefeld:
1376 - Initial infrastructure for running SCons tests under QMTest.
1380 - Fix tests that fail due to gcc warnings.
1382 From Dobes Vandermeer:
1384 - In stack traces, print the full paths of SConscript files.
1388 - Fix detection of Visual C++ Express Edition.
1390 From Dobes Vandermeer:
1392 - Let the src_dir option to the SConscript() function affect all the
1393 the source file paths, instead of treating all source files paths
1394 as relative to the SConscript directory itself.
1396 From Nicolas Vigier:
1398 - Fix finding Fortran modules in build directories.
1400 - Fix use of BuildDir() when the source file in the source directory
1401 is a symlink with a relative path.
1405 - Fix the Memoizer when the SCons Python modules are executed from
1406 .pyo files at different locations from where they were compiled.
1410 - Fix missing os.path.join() when constructing the $FRAMEWORKSDKDIR/bin.
1414 RELEASE 0.96.92 - Mon, 10 Apr 2006 21:08:22 -0400
1416 NOTE: This was a pre-release of 0.97 for testing purposes.
1420 - Fix the intelc.py Tool module to not throw an exception if the
1421 only installed version is something other than ia32.
1423 - Set $CCVERSION when using gcc.
1427 - Support generating project and solution files for Microsoft
1428 Visual Studio version 8.
1430 - Support generating more than one project file for a Microsoft
1431 Visual Studio solution file.
1433 - Add support for a support "runfile" parameter to Microsoft
1434 Visual Studio project file creation.
1436 - Put the project GUID, not the solution GUID, in the right spot
1437 in the solution file.
1439 From Erling Andersen:
1441 - Fix interpretation of Node.FS objects wrapped in Proxy instances,
1442 allowing expansion of things like ${File(TARGET)} in command lines.
1444 From Stanislav Baranov:
1446 - Add a separate MSVSSolution() Builder, with support for the
1447 following new construction variables: $MSVSBUILDCOM, $MSVSCLEANCOM,
1448 $MSVSENCODING, $MSVSREBUILDCOM, $MSVSSCONS, $MSVSSCONSCOM,
1449 $MSVSSCONSFLAGS, $MSVSSCONSCRIPT and $MSVSSOLUTIONCOM.
1451 From Ralph W. Grosse-Kunstleve and Patrick Mezard:
1453 - Remove unneceesary (and incorrect) SCons.Util strings on some function
1454 calls in SCons.Util.
1458 - Fix C/C++ compiler selection on AIX to not always use the external $CC
1459 environment variable.
1461 From August Hörandl:
1463 - Add a scanner for \include and \import files, with support for
1464 searching a directory list in $TEXINPUTS (imported from the external
1467 - Support $MAKEINDEX, $MAKEINDEXCOM, $MAKEINDEXCOMSTR and
1468 $MAKEINDEXFLAGS for generating indices from .idx files.
1470 From Steven Johnson:
1472 - Add a NoClean() Environment method and function to override removal
1473 of targets during a -c clean, including documentation and tests.
1477 - Check for whether files exist on disk by listing the directory
1478 contents, not calling os.path.exists() file by file. This is
1479 somewhat more efficient in general, and may be significantly
1480 more efficient on Windows.
1482 - Minor speedups in the internal is_Dict(), is_List() and is_String()
1485 - Fix a signature refactoring bug that caused Qt header files to
1486 get re-generated every time.
1488 - Don't fail when writing signatures if the .sconsign.dblite file is
1489 owned by a different user (e.g. root) from a previous run.
1491 - When deleting variables from stacked OverrideEnvironments, don't
1492 throw a KeyError if we were able to delte the variable from any
1493 Environment in the stack.
1495 - Get rid of the last indentation tabs in the SCons source files and
1496 add -tt to the Python invocations in the packaging build and the
1497 tests so they don't creep back in.
1499 - In Visual Studio project files, put quotes around the -C directory
1500 so everything works even if the path has spaces in it.
1502 - The Intel Fortran compiler uses -object:$TARGET, not "-o $TARGET",
1503 when building object files on Windows. Have the the ifort Tool
1504 modify the default command lines appropriately.
1506 - Document the --debug=explain option in the man page. (How did we
1509 - Add a $LATEXRETRIES variable to allow configuration of the number of
1510 times LaTex can be re-called to try to resolve undefined references.
1512 - Change the order of the arguments to Configure.Checklib() to match
1515 - Handle signature calculation properly when the Python function used
1516 for a FunctionAction is an object method.
1518 - On Windows, assume that absolute path names without a drive letter
1519 refer to the drive on which the SConstruct file lives.
1521 - Add /usr/ccs/bin to the end of the the default external execution
1524 - Add $PKGCHK and $PKGINFO variables for use on Solaris when searching
1525 for the SunPRO C++ compiler. Make the default value for $PKGCHK
1526 be /usr/sbin/pgkchk (since /usr/sbin isn't usually on the external
1529 - Fix a man page example of overriding variables when calling
1530 SharedLibrary() to also set the $LIBSUFFIXES variable.
1532 - Add a --taskmastertrace=FILE option to give some insight on how
1533 the taskmaster decides what Node to build next.
1535 - Changed the names of the old $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
1536 $WIN32DLLPREFIX and $WIN32IMPLIBPREFIX construction variables to
1537 new $WINDOWSDEFPREFIX, $WINDOWSDEFSUFFIX, $WINDOWSDLLPREFIX and
1538 $WINDOWSIMPLIBPREFIX construction variables. The old names are now
1539 deprecated, but preserved for backwards compatibility.
1541 - Fix (?) a runtest.py hang on Windows when the --xml option is used.
1543 - Change the message when an error occurs trying to interact with the
1544 file system to report the target(s) in square brackets (as before) and
1545 the actual file or directory that encountered the error afterwards.
1549 - Add x64 support for Microsoft Visual Studio 8.
1551 From Baptiste Lepilleur:
1553 - Support the --debug=memory option on Windows when the Python version
1554 has the win32process and win32api modules.
1556 - Add support for Visual Studio 2005 Pro.
1558 - Fix portability issues in various tests: test/Case.py,
1559 Test/Java/{JAR,JARCHDIR,JARFLAGS,JAVAC,JAVACFLAGS,JAVAH,RMIC}.py,
1560 test/MSVS/vs-{6.0,7.0,7.1,8.0}-exec.py,
1561 test/Repository/{Java,JavaH,RMIC}.py,
1562 test/QT/{generated-ui,installed,up-to-date,warnings}.py,
1565 - Ignore pkgchk errors on Solaris when searching for the C++ compiler.
1567 - Speed up the SCons/EnvironmentTests.py unit tests.
1569 - Add a --verbose= option to runtest.py to print executed commands
1570 and their output at various levels.
1572 From Christian Maaser:
1574 - Add support for Visual Studio Express Editions.
1576 - Add support for Visual Studio 8 *.manifest files, includng
1577 new $WINDOWS_INSERT_MANIFEST, $WINDOWSPROGMANIFESTSUFFIX,
1578 $WINDOWSPROGMANIFESTPREFIX, $WINDOWSPROGMANIFESTSUFFIX,
1579 $WINDOWSSHLIBMANIFESTPREFIX and $WINDOWSSHLIBMANIFESTSUFFIX
1580 construction variables.
1584 - Fix detection of additional Java inner classes following use of a
1585 "new" keyword inside an inner class.
1587 From Sanjoy Mahajan:
1589 - Correct TeX-related command lines to just $SOURCE, not $SOURCES
1591 From Patrick Mezard:
1593 - Execute build commands for a command-line target if any of the
1594 files built along with the target is out of date or non-existent,
1595 not just if the command-line target itself is out of date.
1597 - Fix the -n option when used with -c to print all of the targets
1598 that will be removed for a multi-target Builder call.
1600 - If there's no file in the source directory, make sure there isn't
1601 one in the build directory, too, to avoid dangling files left
1602 over from previous runs when a source file is removed.
1604 - Allow AppendUnique() and PrependUnique() to append strings (and
1605 other atomic objects) to lists.
1607 From Joel B. Mohler:
1609 - Extend latex.py, pdflatex.py, pdftex.py and tex.py so that building
1610 from both TeX and LaTeX files uses the same logic to call $BIBTEX
1611 when it's necessary, to call $MAKEINDEX when it's necessary, and to
1612 call $TEX or $LATEX multiple times to handle undefined references.
1614 - Add an emitter to the various TeX builders so that the generated
1615 .aux and .log files also get deleted by the -c option.
1617 From Leanid Nazdrynau:
1619 - Fix the Qt UIC scanner to work with generated .ui files (by using
1620 the FindFile() function instead of checking by-hand for the file).
1622 From Jan Nieuwenhuizen:
1624 - Fix a problem with interpreting quoted argument lists on command lines.
1628 - Add /sw/bin to the default execution PATH on Mac OS X.
1632 - When building a .jar file and there is a $JARCHDIR, put the -C
1633 in front of each .class file on the command line.
1635 - Recognize the Java 1.5 enum keyword.
1637 From Asfand Yar Qazi:
1639 - Add /opt/bin to the default execution PATH on all POSIX platforms
1640 (between /usr/local/bin and /bin).
1644 - Fix the use of Configure() contexts from nested subsidiary
1647 From Christoph Schulz:
1649 - Add support for $CONFIGUREDIR and $CONFIGURELOG variables to control
1650 the directory and logs for configuration tests.
1652 - Add support for a $INSTALLSTR variable.
1654 - Add support for $RANLIBCOM and $RANLIBCOMSTR variables (which fixes
1655 a bug when setting $ARCOMSTR).
1659 - Add use of $CPPDEFINES to $RCCOM (resource file compilation) on MinGW.
1661 From Erick Tryzelaar:
1663 - Fix the error message when trying to report that a given option is
1664 not gettable/settable from an SConscript file.
1666 From Dobes Vandermeer:
1668 - Add support for SCC and other settings in Microsoft Visual
1669 Studio project and solution files: $MSVS_PROJECT_BASE_PATH,
1670 $MSVS_PROJECT_GUID, $MSVS_SCC_AUX_PATH, $MSVS_SCC_LOCAL_PATH,
1671 $MSVS_SCC_PROJECT_NAME, $MSVS_SCC_PROVIDER,
1673 - Add support for using a $SCONS_HOME variable (imported from the
1674 external environment, or settable internally) to put a shortened
1675 SCons execution line in the Visual Studio project file.
1677 From David J. Van Maren:
1679 - Only filter common prefixes from source files names in Visual Studio
1680 project files if the prefix is a complete (sub)directory name.
1684 - If $MSVSVERSIONS is already set, don't overwrite it with
1685 information from the registry.
1689 RELEASE 0.96.91 - Thu, 08 Sep 2005 07:18:23 -0400
1691 NOTE: This was a pre-release of 0.97 for testing purposes.
1695 - Have the environment store the toolpath and re-use it to find Tools
1696 modules during later Copy() or Tool() calls (unless overridden).
1698 - Normalize the directory path names in SConsignFile() database
1699 files so the same signature file can interoperate on Windows and
1700 non-Windows systems.
1702 - Make --debug=stacktrace print a stacktrace when a UserError is thrown.
1704 - Remove an old, erroneous cut-and-paste comment in Scanner/Dir.py.
1706 From Stanislav Baranov:
1708 - Make it possible to support with custom Alias (sub-)classes.
1710 - Allow Builders to take empty source lists when called.
1712 - Allow access to both TARGET and SOURCE in $*PATH expansions.
1714 - Allow SConscript files to modify BUILD_TARGETS.
1716 From Timothee Besset:
1718 - Add support for Objective C/C++ .m and .mm file suffixes (for
1723 - Fix the PharLap linkloc.py module to use target+source arguments
1724 when calling env.subst().
1726 From Bjorn Eriksson:
1728 - Fix an incorrect Command() keyword argument in the man page.
1730 - Add a $TEMPFILEPREFIX variable to control the prefix or flag used
1731 to pass a long-command-line-execution tempfile to a command.
1735 - Enhanced the SCons setup.py script to install man pages on
1738 - Add support for an Options.FormatOptionHelpText() method that can
1739 be overridden to customize the format of Options help text.
1741 - Add a global name for the Entry class (which had already been
1744 - Fix re-scanning of generated source files for implicit dependencies
1745 when the -j option is used.
1747 - Fix a dependency problem that caused $LIBS scans to not be added
1748 to all of the targets in a multiple-target builder call, which
1749 could cause out-of-order builds when the -j option is used.
1751 - Store the paths of source files and dependencies in the .sconsign*
1752 file(s) relative to the target's directory, not relative to the
1753 top-level SConstruct directory. This starts to make it possible to
1754 subdivide the dependency tree arbitrarily by putting an SConstruct
1755 file in every directory and using content signatures.
1757 - Add support for $YACCHFILESUFFIX and $YACCHXXFILESUFFIX variables
1758 that accomodate parser generators that write header files to a
1759 different suffix than the hard-coded .hpp when the -d option is used.
1761 - The default behavior is now to store signature information in a
1762 single .sconsign.dblite file in the top-level SConstruct directory.
1763 The old behavior of a separate .sconsign file in each directory can
1764 be specified by calling SConsignFile(None).
1766 - Remove line number byte codes within the signature calculation
1767 of Python function actions, so that changing the location of an
1768 otherwise unmodified Python function doesn't cause rebuilds.
1770 - Fix AddPreAction() and AddPostAction() when an action has more than
1771 one target file: attach the actions to the Executor, not the Node.
1773 - Allow the source directory of a BuildDir / build_dir to be outside
1774 of the top-level SConstruct directory tree.
1776 - Add a --debug=nomemoizer option that disables the Memoizer for clearer
1777 looks at the counts and profiles of the underlying function calls,
1778 not the Memoizer wrappers.
1780 - Print various --debug= stats even if we exit early (e.g. using -h).
1782 - Really only use the cached content signature value if the file
1783 is older than --max-drift, not just if --max-drift is set.
1785 - Remove support for conversion from old (pre 0.96) .sconsign formats.
1787 - Add support for a --diskcheck option to enable or disable various
1788 on-disk checks: that File and Dir nodes match on-disk entries;
1789 whether an RCS file exists for a missing source file; whether an
1790 SCCS file exists for a missing source file.
1792 - Add a --raw argument to the sconsign script, so it can print a
1793 raw representation of each entry's NodeInfo dictionary.
1795 - Add the 'f90' and 'f95' tools to the list of Fortran compilers
1796 searched for by default.
1798 - Add the +Z option by default when compiling shared objects on
1803 - Handle Visual Studio project and solution files in Unicode.
1805 From Sanjoy Mahajan:
1807 - Fix a bad use of Copy() in an example in the man page, and a
1808 bad regular expression example in the man page and User's Guide.
1812 - Have the Visual Studio project file(s) echo "Starting SCons" before
1813 executing SCons, mainly to work around a quote-stripping bug in
1814 (some versions of?) the Windows cmd command executor.
1816 From Georg Mischler:
1818 - Remove the space after the -o option when invoking the Borland
1819 BCC compiler; some versions apparently require that the file name
1820 argument be concatenated with the option.
1822 From Leanid Nazdrynau:
1824 - Fix the Java parser's handling of backslashes in strings.
1828 - Add construction variables to support frameworks on Mac OS X:
1829 $FRAMEWORKS, $FRAMEWORKPREFIX, $FRAMEWORKPATH, $FRAMEWORKPATHPREFIX.
1831 - Re-order link lines so the -o option always comes right after the
1834 From Gary Oberbrunner:
1836 - Add support for Intel C++ beta 9.0 (both 32 and 64 bit versions).
1838 - Document the new $FRAMEWORK* variables for Mac OS X.
1840 From Karol Pietrzak:
1842 - Add $RPATH (-R) support to the Sun linker Tool (sunlink).
1844 - Add a description of env.subst() to the man page.
1848 - Look in the right directory, not always the local directory, for a
1849 same-named file or directory conflict on disk.
1851 - On Windows, preserve the external environment's %SYSTEMDRIVE%
1856 - Have the Fortran module emitter look for Fortan modules to be created
1857 relative to $FORTRANMODDIR, not the top-level directory.
1859 - When saving Options to a file, run default values through the
1860 converter before comparing them with the set values. This correctly
1861 suppresses Boolean Option values from getting written to the saved
1862 file when they're one of the many synonyms for a default True or
1865 - Fix the Fortran Scanner's ability to handle a module being used
1866 in the same file in which it is defined.
1870 - Add the -KPIC option by default when compiling shared objects on
1873 - Change the default suffix for Solaris objects to .o, to conform to
1874 Sun WorkShop's expectations. Change the profix to so_ so they can
1875 still be differentiated from static objects in the same directory.
1879 - When calling the resource compiler on MinGW, add --include-dir and
1880 the source directory so it finds the source file.
1882 - Update EnsureSConsVersion() to support revision numbers.
1886 - Fix a misplaced line in the man page.
1890 RELEASE 0.96.90 - Tue, 15 Feb 2005 21:21:12 +0000
1892 NOTE: This was a pre-release of 0.97 for testing purposes.
1896 - Fix Java parsing to avoid erroneously identifying a new array
1897 of class instances as an anonymous inner class.
1899 - Fix a typo in the man page description of PathIsDirCreate.
1903 - Allow Help() to be called multiple times, appending to the help
1906 - Allow Tools found on a toolpath to import Python modules from
1907 their local directory.
1909 From Steve Christensen:
1911 - Handle exceptions from Python functions as build actions.
1913 - Add a set of canned PathOption validators: PathExists (the default),
1914 PathIsFile, PathIsDir and PathIsDirCreate.
1918 - Add support for .lex and .yacc file suffixes for Lex and Yacc files.
1922 - Huge performance improvement: wrap the tuples representing an
1923 include path in an object, so that the time it takes to hash the
1924 path doesn't grow porportionally to the length of the path.
1926 From Gottfried Ganssauge:
1928 - Fix SCons on SuSE/AMD-64 Linux by having the wrapper script also
1929 check for the build engine in the parent directory of the Python
1930 library directory (/usr/lib64 instead of /usr/lib).
1932 From Stephen Kennedy:
1934 - Speed up writing the .sconsign file at the end of a run by only
1935 calling sync() once at the end, not after every entry.
1939 - When compiling with Microsoft Visual Studio, don't include the ATL and
1940 MFC directories in the default INCLUDE and LIB environment variables.
1942 - Remove the following deprecated features: the ParseConfig()
1943 global function (deprecated in 0.93); the misspelled "validater"
1944 keyword to the Options.Add() method (deprecated in 0.91); the
1945 SetBuildSignatureType(), SetContentSignatureType(), SetJobs() and
1946 GetJobs() global functions (deprecated in 0.14).
1948 - Fix problems with corrupting the .sconsign.dblite file when
1949 interrupting builds by writing to a temporary file and renaming,
1950 not writing the file directly.
1952 - Fix a 0.96 regression where when running with -k, targets built from
1953 walking dependencies later on the command line would not realize
1954 that a dependency had failed an earlier build attempt, and would
1955 try to rebuild the dependent targets.
1957 - Change the final messages when using -k and errors occur from
1958 "{building,cleaning} terminated because of errors" to "done
1959 {building,cleaning} targets (errors occurred during {build,clean})."
1961 - Allow Configure.CheckFunc() to take an optional header argument
1962 (already supported by Conftest.py) to specify text at the top of
1963 the compiled test file.
1965 - Fix the --debug=explain output when a Python function action changed
1966 so it prints a meaningful string, not the binary representation of
1967 the function contents.
1969 - Allow a ListOption's default value(s) to be a Python list of specified
1970 values, not just a string containing a comma-separated list of names.
1972 - Add a ParseDepends() function that will parse up a list of explicit
1973 dependencies from a "make depend" style file.
1975 - Support the ability to change directory when executing an Action
1976 through "chdir" keyword arguments to Action and Builder creation
1979 - Fix handling of Action ojects (and other callables that don't match
1980 our calling arguments) in construction variable expansions.
1982 - On Win32, install scons.bat in the Python directory when installing
1983 from setup.py. (The bdist_wininst installer was already doing this.)
1985 - Fix env.SConscript() when called with a list of SConscipt files.
1986 (The SConscript() global function already worked properly.)
1988 - Add a missing newline to the end of the --debug=explain "unknown
1991 - Enhance ParseConfig() to work properly for spaces in between the -I,
1992 -L and -l options and their arguments.
1994 - Packaging build fix: Rebuild the files that are use to report the
1995 --version of SCons whenever the development version number changes.
1997 - Fix the ability to specify a target_factory of Dir() to a Builder,
1998 which the default create-a-directory Builder was interfering with.
2000 - Mark a directory as built if it's created as part of the preparation
2001 for another target, to avoid trying to build it again when it comes
2002 up in the target list.
2004 - Allow a function with the right calling signature to be put directly
2005 in an Environment's BUILDERS dictionary, making for easier creation
2006 and use of wrappers (pseudo-Builders) that call other Builders.
2008 - On Python 2.x, wrap lists of Nodes returned by Builders in a UserList
2009 object that adds a method that makes str() object return a string
2010 with all of the Nodes expanded to their path names. (Builders under
2011 Python 1.5.2 still return lists to avoid TypeErrors when trying
2012 to extend() list, so Python 1.5.2 doesn't get pretty-printing of Node
2013 lists, but everything should still function.)
2015 - Allow Aliases to have actions that will be executed whenever
2016 any of the expanded Alias targets are out of date.
2018 - Fix expansion of env.Command() overrides within target and
2021 - Support easier customization of what's displayed by various default
2022 actions by adding lots of new construction variables: $ARCOMSTR,
2023 $ASCOMSTR, $ASPPCOMSTR, $BIBTEXCOMSTR, $BITKEEPERCOMSTR, $CCCOMSTR,
2024 $CVSCOMSTR, $CXXCOMSTR, $DCOMSTR, $DVIPDFCOMSTR, $F77COMSTR,
2025 $F90COMSTR, $F95COMSTR, $FORTRANCOMSTR, $GSCOMSTR, $JARCOMSTR,
2026 $JAVACCOMSTR, $JAVAHCOMSTR, $LATEXCOMSTR, $LEXCOMSTR, $LINKCOMSTR,
2027 $M4COMSTR, $MIDLCOMSTR, $P4COMSTR, $PCHCOMSTR, $PDFLATEXCOMSTR,
2028 $PDFTEXCOMSTR, $PSCOMSTR, $QT_MOCFROMCXXCOMSTR, $QT_MOCFROMHCOMSTR,
2029 $QT_UICCOMSTR, $RCCOMSTR, $REGSVRCOMSTR, $RCS_COCOMSTR, $RMICCOMSTR,
2030 $SCCSCOMSTR, $SHCCCOMSTR, $SHCXXCOMSTR, $SHF77COMSTR, $SHF90COMSTR,
2031 $SHF95COMSTR, $SHFORTRANCOMSTR, $SHLINKCOMSTR, $SWIGCOMSTR,
2032 $TARCOMSTR, $TEXCOMSTR, $YACCCOMSTR and $ZIPCOMSTR.
2034 - Add an optional "map" keyword argument to ListOption() that takes a
2035 dictionary to map user-specified values to legal values from the list
2036 (like EnumOption() already doee).
2038 - Add specific exceptions to try:-except: blocks without any listed,
2039 so that they won't catch and mask keyboard interrupts.
2041 - Make --debug={tree,dtree,stree} print something even when there's
2044 - Fix how Scanners sort the found dependencies so that it doesn't
2045 matter whether the dependency file is in a Repository or not.
2046 This may cause recompilations upon upgrade to this version.
2048 - Make AlwaysBuild() work with Alias and Python value Nodes (making
2049 it much simpler to support aliases like "clean" that just invoke
2050 an arbitrary action).
2052 - Have env.ParseConfig() use AppendUnique() by default to suppress
2053 duplicate entries from multiple calls. Add a "unique" keyword
2054 argument to allow the old behavior to be specified.
2056 - Allow the library modules imported by an SConscript file to get at
2057 all of the normally-available global functions and variables by saying
2058 "from SCons.Script import *".
2060 - Add a --debug=memoizer option to print Memoizer hit/mass statistics.
2062 - Allow more than one --debug= option to be set at a time.
2064 - Change --debug=count to report object counts before and after
2065 reading SConscript files and before and after building targets.
2067 - Change --debug=memory output to line up the numbers and to better
2068 match (more or less) the headers on the --debug=count columns.
2070 - Speed things up when there are lists of targets and/or sources by
2071 getting rid of some N^2 walks of the lists involved.
2073 - Cache evaluation of LazyActions so we don't create a new object
2074 for each invocation.
2076 - When scanning, don't create Nodes for include files that don't
2077 actually exist on disk.
2079 - Make supported global variables CScanner, DScanner, ProgramScanner and
2080 SourceFileScanner. Make SourceFileScanner.add_scanner() a supported
2081 part of the public interface. Keep the old SCons.Defaults.*Scan names
2082 around for a while longer since some people were already using them.
2084 - By default, don't scan directories for on-disk files. Add a
2085 DirScanner global scanner that can be used in Builders or Command()
2086 calls that want source directory trees scanned for on-disk changes.
2087 Have the Tar() and Zip() Builders use the new DirScanner to preserve
2088 the behavior of rebuilding a .tar or .zip file if any file or
2089 directory under a source tree changes. Add Command() support for
2090 a source_scanner keyword argument to Command() that can be set to
2091 DirScanner to get this behavior.
2093 - Documentation changes: Explain that $CXXFLAGS contains $CCFLAGS
2094 by default. Fix a bad target_factory example in the man page.
2095 Add appendices to the User's Guide to cover the available Tools,
2096 Builders and construction variables. Comment out the build of
2097 the old Python 10 paper, which doesn't build on all systems and
2098 is old enough at this point that it probably isn't worth the
2099 effort to make it do so.
2103 - Avoid "maximum recursion limit" errors when removing $(-$) pairs
2104 from long command lines.
2106 From Clive Levinson:
2108 - Make ParseConfig() recognize and add -mno-cygwin to $LINKFLAGS and
2109 $CCFLAGS, and -mwindows to $LINKFLAGS.
2111 From Michael McCracken:
2113 - Add a new "applelink" tool to handle the things like Frameworks and
2114 bundles that Apple has added to gcc for linking.
2116 - Use more appropriate default search lists of linkers, compilers and
2117 and other tools for the 'darwin' platform.
2119 - Add a LoadableModule Builder that builds a bundle on Mac OS X (Darwin)
2120 and a shared library on other systems.
2122 - Improve SWIG tests for use on Mac OS X (Darwin).
2126 - Enhance the tests to guarantee persistence of ListOption
2127 values in saved options files.
2129 - Supply the help text when -h is used with the -u, -U or -D options.
2131 From Christian Neeb:
2133 - Fix the Java parser's handling of string definitions to avoid ignoring
2136 From Han-Wen Nienhuys:
2138 - Optimize variable expansion by: using the re.sub() method (when
2139 possible); not using "eval" for variables for which we can fetch the
2140 value directory; avoiding slowing substitution logic when there's no
2143 From Gary Oberbrunner:
2145 - Add an Environment.Dump() method to print the contents of a
2146 construction environment.
2148 - Allow $LIBS (and similar variables) to contain explicit File Nodes.
2150 - Change ParseConfig to add the found library names directly to the
2151 $LIBS variable, instead of returning them.
2153 - Add ParseConfig() support for the -framework GNU linker option.
2155 - Add a PRINT_CMD_LINE_FUNC construction variable to allow people
2156 to filter (or log) command-line output.
2158 - Print an internal Python stack trace in response to an otherwise
2159 unexplained error when --debug=stacktrace is specified.
2161 - Add a --debug=findlibs option to print what's happening when
2162 the scanner is searching for libraries.
2164 - Allow Tool specifications to be passed a dictionary of keyword
2167 - Support an Options default value of None, in which case the variable
2168 will not be added to the construction environment unless it's set
2169 explicitly by the user or from an Options file.
2171 - Avoid copying __builtin__ values into a construction environment's
2172 dictionary when evaluating construction variables.
2174 - Add a new cross-platform intelc.py Tool that can detect and
2175 configure the Intel C++ v8 compiler on both Windows, where it's
2176 named icl, and Linux, where it's named icc. It also checks that
2177 the directory specified in the Windows registry exists, and sets a
2178 new $INTEL_C_COMPILER_VERSION construction variable to identify the
2179 version being used. (Niall Douglas contributed an early prototype
2180 of parts of this module.)
2182 - Fix the private Conftest._Have() function so it doesn't change
2183 non-alphanumeric characters to underscores.
2185 - Supply a better error message when a construction variable expansion
2186 has an unknown attribute.
2188 - Documentation changes: Update the man page to describe use of
2189 filenames or Nodes in $LIBS.
2193 - Have the linkloc tool use $MSVS_VERSION to select the Microsoft
2194 Visual Studio version to use.
2198 - Fix the Builder name returned from ListBuilders and other instances
2199 of subclasses of the BuilderBase class.
2201 - Add Builders and construction variables to support rpcgen:
2202 RPCGenClient(), RPCGenHeader(), RPCGenService(), RPCGenXDR(),
2203 $RPCGEN, $RPCGENFLAGS, $RPCGENCLIENTFLAGS, $RPCGENHEADERFLAGS,
2204 $RPCGENSERVICEFLAGS, $RPCGENXDRFLAGS.
2206 - Update the man page to document that prefix and suffix Builder
2207 keyword arguments can be strings, callables or dictionaries.
2209 - Provide more info in the error message when a user tries to build
2210 a target multiple ways.
2212 - Fix Delete() when a file doesn't exist and must_exist=1. (We were
2213 unintentionally dependent on a bug in versions of the Python shutil.py
2214 module prior to Python 2.3, which would generate an exception for
2215 a nonexistent file even when ignore_errors was set.)
2217 - Only replace a Node's builder with a non-null source builder.
2219 - Fix a stack trace when a suffix selection dictionary is passed
2220 an empty source file list.
2222 - Allow optional names to be attached to Builders, for default
2223 Builders that don't get attached to construction environments.
2225 - Fix problems with Parallel Task Exception handling.
2227 - Build targets in an associated BuildDir even if there are targets
2228 or subdirectories locally in the source directory.
2230 - If a FunctionAction has a callable class as its underlying Python
2231 function, use its strfunction() method (if any) to display the
2234 - Fix handling when BuildDir() exists but is unwriteable. Add
2235 "Stop." to those error messages for consistency.
2237 - Catch incidents of bad builder creation (without an action) and
2238 supply meaningful error messages.
2240 - Fix handling of src_suffix values that aren't extensions (don't
2243 - Don't retrieve files from a CacheDir, but report what would happen,
2244 when the -n option is used.
2246 - Use the source_scanner from the target Node, not the source node
2249 - Internal Scanners fixes: Make sure Scanners are only passed Nodes.
2250 Fix how a Scanner.Selector called its base class initialization.
2251 Make comparisons of Scanner objects more robust. Add a name to
2252 an internal default ObjSourceScanner.
2254 - Add a deprecated warning for use of the old "scanner" keyword argument
2255 to Builder creation.
2257 - Improve the --debug=explain message when the build action changes.
2259 - Test enhancements in SourceCode.py, option-n.py, midl.py. Better
2260 Command() and Scanner test coverage. Improved test infrastructure
2263 - Refactor the interface between Action and Executor objects to treat
2266 - The --debug=presub option will now report the pre-substitution
2267 each action seprately, instead of reporting the entire list before
2268 executing the actions one by one.
2270 - The --debug=explain option explaining a changed action will now
2271 (more correctly) show pre-substitution action strings, instead of
2272 the commands with substituted file names.
2274 - A Node (file) will now be rebuilt if its PreAction or PostAction
2277 - Python Function actions now have their calling signature (target,
2278 source, env) reported correctly when displayed.
2280 - Fix BuildDir()/build_dir handling when the build_dir is underneath
2281 the source directory and trying to use entries from the build_dir
2282 as sources for other targets in the build-dir.
2284 - Fix hard-coding of JDK path names in various Java tests.
2286 - Handle Python stack traces consistently (stop at the SConscript stack
2287 frame, by default) even if the Python source code isn't available.
2289 - Improve the performance of the --debug={tree,dtree} options.
2291 - Add --debug=objects logging of creation of OverrideWarner,
2292 EnvironmentCopy and EnvironmentOverride objects.
2294 - Fix command-line expansion of Python Value Nodes.
2296 - Internal cleanups: Remove an unnecessary scan argument. Associate
2297 Scanners only with Builders, not nodes. Apply overrides once when
2298 a Builder is called, not in multiple places. Cache results from the
2299 Node.FS.get_suffix() and Node.get_build_env() methods. Use the Python
2300 md5 modules' hexdigest() method, if there is one. Have Taskmaster
2301 call get_stat() once for each Node and re-use the value instead of
2302 calling it each time it needs the value. Have Node.depends_on()
2303 re-use the list from the children() method instead of calling it
2306 - Use the correct scanner if the same source file is used for targets in
2307 two different environments with the same path but different scanners.
2309 - Collect logic for caching values in memory in a Memoizer class,
2310 which cleans up a lot of special-case code in various methods and
2311 caches additional values to speed up most configurations.
2313 - Add a PathAccept validator to the list of new canned PathOption
2318 - Documentation changes: Use $CPPDEFINES instead of $CCFLAGS in man
2323 - Allow $JARCHDIR to be expanded to other construction variables.
2325 From Christoph Wiedemann:
2327 - Add an Environment.SetDefault() method that only sets values if
2328 they aren't already set.
2330 - Have the qt.py Tool not override variables already set by the user.
2332 - Add separate $QT_BINPATH, $QT_CPPPATH and $QT_LIBPATH variables
2333 so these can be set individually, instead of being hard-wired
2336 - The %TEMP% and %TMP% external environment variables are now propagated
2337 automatically to the command execution environment on Windows systems.
2339 - A new --config= command-line option allows explicit control of
2340 of when the Configure() tests are run: --config=force forces all
2341 checks to be run, --config=cache uses all previously cached values,
2342 --config=auto (the default) runs tests only when dependency analysis
2343 determines it's necessary.
2345 - The Configure() subsystem can now write a config.h file with values
2346 like HAVE_STDIO_H, HAVE_LIBM, etc.
2348 - The Configure() subsystem now executes its checks silently when the
2349 -Q option is specified.
2351 - The Configure() subsystem now reports if a test result is being
2352 taken from cache, and prints the standard output and error output
2353 of tests even when cached.
2355 - Configure() test results are now reported as "yes" or "no" instead of
2358 - Fixed traceback printing when calling the env.Configure() method
2359 instead of the Configure() global function.
2361 - The Configure() subsystem now caches build failures in a .sconsign
2362 file in the subdirectory, not a .cache file. This may cause
2363 tests to be re-executed the first time after you install 0.97.
2365 - Additional significant internal cleanups in the Configure() subsystem
2368 - Have the Qt Builder make uic-generated files dependent on the .ui.h
2369 file, if one exists.
2371 - Add a test to make sure that SCons source code does not contain
2372 try:-except: blocks that catch all errors, which potentially catch
2373 and mask keyboard interrupts.
2375 - Fix us of TargetSignatures('content') with the SConf subsystem.
2377 From Russell Yanofsky:
2379 - Add support for the Metrowerks Codewarrior compiler and linker
2384 RELEASE 0.96.1 - Mon, 23 Aug 2004 12:55:50 +0000
2386 From Craig Bachelor:
2388 - Handle white space in the executable Python path name within in MSVS
2389 project files by quoting the path.
2391 - Correct the format of a GUID string in a solution (.dsw) file so
2392 MSVS can correctly "build enable" a project.
2396 - Add a must_exist flag to Delete() to let the user control whether
2397 it's an error if the specified entry doesn't exist. The default
2398 behavior is now to silently do nothing if it doesn't exist.
2400 - Package up the new Platform/darwin.py, mistakenly left out of 0.96.
2402 - Make the scons.bat REM statements into @REM so they aren't printed.
2404 - Make the SCons packaging SConscript files platform independent.
2408 - Fix scanning of pre-compiled header (.pch) files for #includes,
2413 RELEASE 0.96 - Wed, 18 Aug 2004 13:36:40 +0000
2417 - Make the CacheDir() directory if it doesn't already exist.
2419 - Allow construction variable substitutions in $LIBS specifications.
2421 - Allow the emitter argument to a Builder() to be or expand to a list
2422 of emitter functions, which will be called in sequence.
2424 - Suppress null values in construction variables like $LIBS that use
2425 the internal _concat() function.
2427 - Remove .dll files from the construction variables searched for
2428 libraries that can be fed to Win32 compilers.
2430 From Chad Austin and Christoph Wiedemann:
2432 - Add support for a $RPATH variable to supply a list of directories
2433 to search for shared libraries when linking a program. Used by
2434 the GNU and IRIX linkers (gnulink and sgilink).
2438 - Restore the ability to do construction variable substitutions in all
2439 kinds of *PATH variables, even when the substitution returns a Node
2444 - Allow the Java() Builder to take more than one source directory.
2446 From Ralf W. Grosse-Kunstleve:
2448 - Have SConsignFile() use, by default, a custom "dblite.py" that we can
2449 control and guarantee to work on all Python versions (or nearly so).
2451 From Jonathan Gurley:
2453 - Add support for the newer "ifort" versions of the Intel Fortran
2458 - Make the new *FLAGS variable type work with copied Environments.
2460 From Chris Hoeppler:
2462 - Initialize the name of a Scanner.Classic scanner correctly.
2466 - Add support for the .dylib shared library suffix and the -dynamiclib
2467 linker option on Mac OS X.
2471 - Add an Execute() method for executing actions directly.
2473 - Support passing environment override keyword arguments to Command().
2475 - Fix use of $MSVS_IGNORE_IDE_PATHS, which was broken when we added
2476 support for $MSVS_USE_MFC_DIRS last release.
2478 - Make env.Append() and env.Prepend() act like the underlying Python
2479 behavior when the variable being appended to is a UserList object.
2481 - Fix a regression that prevented the Command() global function in
2482 0.95 from working with command-line strings as actions.
2484 - Fix checking out a file from a source code management system when
2485 the env.SourceCode() method was called with an individual file name
2486 or node, not a directory name or node.
2488 - Enhance the Task.make_ready() method to create a list of the
2489 out-of-date Nodes for the task for use by the wrapping interface.
2491 - Allow Scanners to pull the list of suffixes from the construction
2492 environment when the "skeys" keyword argument is a string containing
2493 a construction variable to be expanded.
2495 - Support new $CPPSUFFIXES, $DSUFFIXES $FORTRANSUFFIXES, and
2496 $IDLSUFFIXES. construction variables that contain the default list
2497 of suffixes to be scanned by a given type of scanner, allowing these
2498 suffix lists to be easily added to or overridden.
2500 - Speed up Node creation when calling a Builder by comparing whether two
2501 Environments are the same object, not if their underlying dictionaries
2504 - Add a --debug=explain option that reports the reason(s) why SCons
2505 thinks it must rebuild something.
2507 - Add support for functions that return platform-independent Actions
2508 to Chmod(), Copy(), Delete(), Mkdir(), Move() and Touch() files
2509 and/or directories. Like any other Actions, the returned Action
2510 object may be executed directly using the Execute() global function
2511 or env.Execute() environment method, or may be used as a Builder
2512 action or in an env.Command() action list.
2514 - Add support for the strfunction argument to all types of Actions:
2515 CommandAction, ListAction, and CommandGeneratorAction.
2517 - Speed up turning file system Nodes into strings by caching the
2518 values after we're finished reading the SConscript files.
2520 - Have ParseConfig() recognize and supporting adding the -Wa, -Wl,
2521 and -Wp, flags to ASFLAGS, LINKFLAGS and CPPFLAGS, respectively.
2523 - Change the .sconsign format and the checks for whether a Node is
2524 up-to-date to make dependency checks more efficient and correct.
2526 - Add wrapper Actions to SCons.Defaults for $ASCOM, $ASPPCOM, $LINKCOM,
2527 $SHLINKCOM, $ARCOM, $LEXCOM and $YACCCOM. This makes it possible
2528 to replace the default print behavior with a custom strfunction()
2531 - When a Node has been built, don't walk the whole tree back to delete
2532 the parents's implicit dependencies, let returning up the normal
2533 Taskmaster descent take care of it for us.
2535 - Add documented support for separate target_scanner and source_scanner
2536 arguments to Builder creation, which allows different scanners to
2537 be applied to source files
2539 - Don't re-install or (re-generate) .h files when a subsidiary #included
2540 .h file changes. This eliminates incorrect circular dependencies
2541 with .h files generated from other source files.
2543 - Slim down the internal Sig.Calculator class by eliminating methods
2544 whose functionality is now covered by Node methods.
2546 - Document use of the target_factory and source_factory keyword
2547 arguments when creating Builder objects. Enhance Dir Nodes so that
2548 they can be created with user-specified Builder objects.
2550 - Don't blow up with stack trace when the external $PATH environment
2553 - Make Builder calls return lists all the time, even if there's only
2554 one target. This keeps things consistent and easier to program to
2557 - Add a Flatten() function to make it easier to deal with the Builders
2558 all returning lists of targets, not individual targets.
2560 - Performance optimizations in Node.FS.__doLookup().
2562 - Man page fixes: formatting typos, misspellings, bad example.
2564 - User's Guide fixes: Fix the signatures of the various example
2565 *Options() calls. Triple-quote properly a multi-line Split example.
2567 - User's Guide additions: Chapter describing File and Directory
2568 Nodes. Section describing declarative nature of SCons functions in
2569 SConscript files. Better organization and clarification of points
2570 raised by Robert P. J. Day. Chapter describing SConf (Autoconf-like)
2571 functionality. Chapter describing how to install Python and
2572 SCons. Chapter describing Java builds.
2576 - Add a .win32 attribute to force file names to expand with
2577 Windows backslash path separators.
2579 - Fix escaping file names on command lines when the expansion is
2580 concatenated with another string.
2582 - Add support for Fortran 90 and Fortran 95. This adds $FORTRAN*
2583 variables that specify a default compiler, command-line, flags,
2584 etc. for all Fortran versions, plus separate $F90* and $F95*
2585 variables for when different compilers/flags/etc. must be specified
2586 for different Fortran versions.
2588 - Have individual tools that create libraries override the default
2589 $LIBPREFIX and $LIBSUFFIX values set by the platform. This makes
2590 it easier to use Microsoft Visual Studio tools on a CygWin platform.
2592 From Gary Oberbrunner:
2594 - Add a --debug=presub option to print actions prior to substitution.
2596 - Add a warning upon use of the override keywords "targets" and
2597 "sources" when calling Builders. These are usually mistakes which
2598 are otherwise silently (and confusingly) turned into construction
2601 - Try to find the ICL license file path name in the external environment
2602 and the registry before resorting to the hard-coded path name.
2604 - Add support for fetching command-line keyword=value arguments in
2605 order from an ARGLIST list.
2607 - Avoid stack traces when trying to read dangling symlinks.
2609 - Treat file "extensions" that only contain digits as part of the
2610 file basename. This supports version numbers as part of shared
2611 library names, for example.
2613 - Avoid problems when there are null entries (None or '') in tool
2616 - Add an example and explanation of how to use "tools = ['default', ..."
2617 when creating a construction environment.
2619 - Add a section describing File and Directory Nodes and some of their
2620 attributes and methods.
2622 - Have ParseConfig() add a returned -pthread flag to both $CCFLAGS
2625 - Fix some test portability issues on Mac OS X (darwin).
2629 - Fix a bug introduced in building shared libraries under MinGW.
2633 - Handling SCons exceptions according to Pythonic standards.
2635 - Fix test/chained-build.py on systems that execute within one second.
2637 - Fix tests on systems where 'ar' warns about archive creation.
2641 - Fix use of the --implicit-cache option with timestamp signatures.
2643 - If Visual Studio is installed, assume the C/C++ compiler, the linker
2644 and the MIDL compiler that comes with it are available, too.
2646 - Better error messages when evaluating a construction variable
2647 expansion yields a Python syntax error.
2649 - Change the generation of PDB files when using Visual Studio from
2650 compile time to link time.
2654 - Allow SConf.CheckLib() to search a list of libraries, like the
2655 Autoconf AC_SEARCH_LIBS macro.
2657 - Allow the env.WhereIs() method to take a "reject" argument to
2658 let it weed out specific path names.
2660 From Christoph Wiedemann:
2662 - Add new Moc() and Uic() Builders for more explicit control over
2663 Qt builds, plus new construction variables to control them:
2664 $QT_AUTOSCAN, $QT_DEBUG, $QT_MOCCXXPREFIX, $QT_MOCCXXSUFFIX,
2665 $QT_MOCHPREFIX, $QT_MOCHSUFFIX, $QT_UICDECLPREFIX, $QT_UICDECLSUFFIX,
2666 $QT_UICIMPLPREFIX, $QT_UICIMPLSUFFIX and $QT_UISUFFIX.
2668 - Add a new single_source keyword argument for Builders that enforces
2669 a single source file on calls to the Builder.
2673 RELEASE 0.95 - Mon, 08 Mar 2004 06:43:20 -0600
2677 - Replace print statements with calls to sys.stdout.write() so output
2678 lines stay together when -j is used.
2680 - Add portability fixes for a number of tests.
2682 - Accomodate the fact that Cygwin's os.path.normcase() lies about
2683 the underlying system being case-sensitive.
2685 - Fix an incorrect _concat() call in the $RCINCFLAGS definition for
2688 - Fix a problem with the msvc tool with Python versions prior to 2.3.
2690 - Add support for a "toolpath" Tool() and Environment keyword that
2691 allows Tool modules to be found in specified local directories.
2693 - Work around Cygwin Python's silly fiction that it's using a
2694 case-sensitive file system.
2696 - More robust handling of data in VCComponents.dat.
2698 - If the "env" command is available, spawn commands with the more
2699 general "env -" instead of "env -i".
2701 From Kerim Borchaev:
2703 - Fix a typo in a msvc.py's registry lookup: "VCComponents.dat", not
2706 From Chris Burghart:
2708 - Fix the ability to save/restore a PackageOption to a file.
2710 From Steve Christensen:
2712 - Update the MSVS .NET and MSVC 6.0/7.0 path detection.
2714 From David M. Cooke:
2716 - Make the Fortran scanner case-insensitive for the INCLUDE string.
2720 - If no version of MSVC is detected but the tool is specified,
2721 use the MSVC 6.0 paths by default.
2723 - Ignore any "6.1" version of MSVC found in the registry; this is a
2724 phony version number (created by later service packs?) and would
2725 throw off the logic if the user had any non-default paths configure.
2727 - Correctly detect if the user has independently configured the MSVC
2728 "include," "lib" or "path" in the registry and use the appropriate
2729 values. Previously, SCons would only use the values if all three
2730 were set in the registry.
2732 - Make sure side-effect nodes are prepare()d before building their
2733 corresponding target.
2735 - Preserve the ability to call BuildDir() multiple times with the
2736 same target and source directory arguments.
2740 - Add support for the Digital Mars "D" programming language.
2742 From Scott Lystig Fritchie:
2744 - Fix the ability to use a custom _concat() function in the
2745 construction environment when calling _stripixes().
2747 - Make the message about ignoring a missing SConscript file into a
2748 suppressable Warning, not a hard-coded sys.stderr.write().
2750 - If a builder can be called multiple times for a target (because
2751 the sources and overrides are identical, or it's a builder with the
2752 "multi" flag set), allow the builder to be called through multiple
2753 environments so long as the builders have the same signature for
2754 the environments in questions (that is, they're the same action).
2758 - When multiple targets are built by a single action, retrieve all
2759 of them from cache, not just the first target, and exec the build
2760 command if any of the targets isn't present in the cache.
2762 From Zephaniah Hull:
2764 - Fix command-line ARGUMENTS with multiple = in them.
2768 - Fix EnsureSConsVersion() so it checks against the SCons version,
2769 not the Python version, on Pythons with sys.version_info.
2771 - Don't swallow the AttributeError when someone uses an expansion like
2772 $TARGET.bak, so we can supply a more informative error message.
2774 - Fix an odd double-quote escape sequence in the man page.
2776 - Fix looking up a naked drive letter as a directory (Dir('C:')).
2778 - Support using File nodes in the LIBS construction variable.
2780 - Allow the LIBS construction variable to be a single string or File
2781 node, not a list, when only one library is needed.
2783 - Fix typos in the man page: JAVACHDIR => JARCHDIR; add "for_signature"
2784 to the __call__() example in the "Variable Substitution" section.
2786 - Correct error message spellings of "non-existant" to "non-existent."
2788 - When scanning for libraries to link with, don't append $LIBPREFIXES
2789 or $LIBSUFFIXES values to the $LIBS values if they're already present.
2791 - Add a ZIPCOMPRESSION construction variable to control whether the
2792 internal Python action for the Zip Builder compresses the file or
2793 not. The default value is zipfile.ZIP_DEFLATED, which generates
2796 - Refactor construction variable expansion to support recursive
2797 expansion of variables (e.g. CCFLAGS = "$CCFLAGS -g") without going
2798 into an infinite loop. Support this in all construction variable
2799 overrides, as well as when copying Environments.
2801 - Fix calling Configure() from more than one subsidiary SConscript file.
2803 - Fix the env.Action() method so it returns the correct type of
2804 Action for its argument(s).
2806 - Fix specifying .class files as input to JavaH with the .class suffix
2807 when they weren't generated using the Java Builder.
2809 - Make the check for whether all of the objects going into a
2810 SharedLibrary() are shared work even if the object was built in a
2813 - Supply meaningful error messages, not stack traces, if we try to add
2814 a non-Node as a source, dependency, or ignored dependency of a Node.
2816 - Generate MSVS Project files that re-invoke SCons properly regardless
2817 of whether the file was built via scons.bat or scons.py.
2818 (Thanks to Niall Douglas for contributing code and testing.)
2820 - Fix TestCmd.py, runtest.py and specific tests to accomodate being
2821 run from directories whose paths include white space.
2823 - Provide a more useful error message if a construction variable
2824 expansion contains a syntax error during evaluation.
2826 - Fix transparent checkout of implicit dependency files from SCCS
2829 - Added new --debug=count, --debug=memory and --debug=objects options.
2830 --debug=count and --debug=objects only print anything when run
2831 under Python 2.1 or later.
2833 - Deprecate the "overrides" keyword argument to Builder() creation
2834 in favor of using keyword argument values directly (like we do
2835 for builder execution and the like).
2837 - Always use the Builder overrides in substitutions, not just if
2838 there isn't a target-specific environment.
2840 - Add new "rsrcpath" and "rsrcdir" and attributes to $TARGET/$SOURCE,
2841 so Builder command lines can find things in Repository source
2842 directories when using BuildDir.
2844 - Fix the M4 Builder so that it chdirs to the Repository directory
2845 when the input file is in the source directory of a BuildDir.
2847 - Save memory at build time by allowing Nodes to delete their build
2848 environments after they've been built.
2850 - Add AppendUnique() and PrependUnique() Environment methods, which
2851 add values to construction variables like Append() and Prepend()
2852 do, but suppress any duplicate elements in the list.
2854 - Allow the 'qt' tool to still be used successfully from a copied
2855 Environment. The include and library directories previously ended up
2856 having the same string re-appended to the end, yielding an incorrect
2859 - Supply a more descriptive error message when the source for a target
2862 - Initialize all *FLAGS variables with objects do the right thing with
2863 appending flags as strings or lists.
2865 - Make things like ${TARGET.dir} work in *PATH construction variables.
2867 - Allow a $MSVS_USE_MFC_DIRS construction variable to control whether
2868 ATL and MFC directories are included in the default INCLUDE and
2871 - Document the dbm_module argument to the SConsignFile() function.
2875 - Add support for the bcc32, ilink32 and tlib Borland tools.
2879 - Supply an error message if the user tries to configure a BuildDir
2880 for a directory that already has one.
2882 - Remove documentation of the still-unimplemented -e option.
2884 - Add -H help text listing the legal --debug values.
2886 - Don't choke if a construction variable is a non-string value.
2888 - Build Type Libraries in the target directory, not the source
2891 - Add an appendix to the User's Guide showing how to accomplish
2892 various common tasks in Python.
2896 - Add support for Microsoft Visual Studio 2003 (version 7.1).
2898 - Evaluate $MSVSPROJECTSUFFIX and $MSVSSOLUTIONSUFFIX when the Builder
2899 is invoked, not when the tool is initialized.
2901 From Christoph Wiedemann:
2903 - When compiling Qt, make sure the moc_*.cc files are compiled using
2904 the flags from the environment used to specify the target, not
2905 the environment that first has the Qt Builders attached.
2909 RELEASE 0.94 - Fri, 07 Nov 2003 05:29:48 -0600
2911 From Hartmut Goebel:
2913 - Add several new types of canned functions to help create options:
2914 BoolOption(), EnumOption(), ListOption(), PackageOption(),
2919 - Fix use of CPPDEFINES with C++ source files.
2921 - Fix env.Append() when the operand is an object with a __cmp__()
2922 method (like a Scanner instance).
2924 - Fix subclassing the Environment and Scanner classes.
2926 - Add BUILD_TARGETS, COMMAND_LINE_TARGETS and DEFAULT_TARGETS variables.
2930 - SGI fixes: Fix C++ compilation, add a separate Tool/sgic++.py module.
2932 From Gary Oberbrunner:
2934 - Fix how the man page un-indents after examples in some browsers.
2938 - Fix the C and C++ tool specifications for AIX.
2942 RELEASE 0.93 - Thu, 23 Oct 2003 07:26:55 -0500
2946 - On POSIX, execute commands with the more modern os.spawnvpe()
2947 function, if it's available.
2949 - Scan .S, .spp and .SPP files for C preprocessor dependencies.
2951 - Refactor the Job.Parallel() class to use a thread pool without a
2952 condition variable. This improves parallel build performance and
2953 handles keyboard interrupts properly when -j is used.
2957 - Add support for a JARCHDIR variable to control changing to a
2958 directory using the jar -C option.
2960 - Add support for detecting Java manifest files when using jar,
2961 and specifying them using the jar m flag.
2963 - Fix some Python 2.2 specific things in various tool modules.
2965 - Support directories as build sources, so that a rebuild of a target
2966 can be triggered if anything underneath the directory changes.
2968 - Have the scons.bat and scons.py files look for the SCons modules
2969 in site-packages as well.
2971 From Christian Engel:
2973 - Support more flexible inclusion of separate C and C++ compilers.
2975 - Use package management tools on AIX and Solaris to find where
2976 the comilers are installed, and what version they are.
2978 - Add support for CCVERSION and CXXVERSION variables for a number
2979 of C and C++ compilers.
2983 - Add test cases for the new capabilities to run bibtex and to rerun
2986 From Ralf W. Grosse-Kunstleve:
2988 - Accomodate anydbm modules that don't have a sync() method.
2990 - Allow SConsignFile() to take an argument specifying the DBM
2993 From Stephen Kennedy:
2995 - Add support for a configurable global .sconsign.dbm file which
2996 can be used to avoid cluttering each directory with an individual
3001 - Fix (re-)scanning of dependencies in generated or installed

3040 - Alphabetize the explanations of the builder methods in the man page.
3042 - Rename the Environment.Environment class to Enviroment.Base.

3063 the one being checked for. (Prototype code contributed by Gerard
3064 Patel and Niall Douglas).
3066 - Supply a warning when -j is used and threading isn't built in to
3067 the current version of Python.
3069 - First release of the User's Guide (finally, and despite a lot
3070 of things still missing from it...).
3074 - Generalize the action for .tex files so that it will decide whether
3075 a file is TeX or LaTeX, check the .aux output to decide if it should
3076 run bibtex, and check the .log output to re-run LaTeX if needed.
3078 From Bram Moolenaar:

3102 From Christoph Wiedemann:
3104 - Fix test/SWIG.py to find the Python include directory in all cases.
3106 - Fix a bug in detection of Qt installed on the local system.

3133 them to instantiation of the default construction environment.
3135 - Update the Debian package so it uses Python 2.2 and more closely
3136 resembles the currently official Debian packaging info.
3140 - When the yacc -d flag is used, take the .h file base name from the
3141 target .c file, not the source (matching what yacc does).
3145 RELEASE 0.91 - Thu, 14 Aug 2003 13:00:44 -0500
3149 - Support specifying a list of tools when calling Environment.Copy().
3151 - Give a Value Nodes a timestamp of the system time when they're

3166 - Make builder prefixes work correctly when deducing a target
3167 from a source file name in another directory.
3169 - Documentation fixes: typo in the man page; explain up-front about
3170 not propagating the external environment.
3172 - Use "cvs co -d" instead of "cvs co -p >" when checking out something
3173 from CVS with a specified module name. This avoids zero-length
3174 files when there is a checkout error.
3176 - Add an "sconsign" script to print the contents of .sconsign files.
3178 - Speed up maintaining the various lists of Node children by using
3179 dictionaries to avoid "x in list" searches.
3181 - Cache the computed list of Node children minus those being Ignored
3182 so it's only calculated once.
3184 - Fix use of the --cache-show option when building a Program()
3185 (or using any other arbitrary action) by making sure all Action

3201 in the source list to pick the right one.
3203 - Refactor the creation of the Program, *Object and *Library Builders
3204 so that they're moved out of SCons.Defaults and created on demand.

3213 of the suffixes we use as C++ files.
3215 - Allow the "prefix" and "suffix" attributes of a Builder to be
3216 callable objects that return generated strings, or dictionaries
3217 that map a source file suffix to the right prefix/suffix.
3219 - Support a MAXLINELINELENGTH construction variable on Win32 systems
3220 to control when a temporary file is used for long command lines.
3222 - Make how we build .rpm packages not depend on the installation
3223 locations from the distutils being used.
3225 - When deducing a target Node, create it directly from the first
3226 source Node, not by trying to create the right string to pass to
3229 - Add support for SWIG.

3233 - Test portability fixes for FreeBSD.
3235 From Gary Oberbrunner:
3237 - Report the target being built in error messages when building

3239 extension can't be deduced, or when we don't have an action for a
3242 - Provide helpful error messages when the arguments to env.Install()
3245 - Fix the value returned by the Node.prevsiginfo() method to conform
3246 to a previous change when checking whether a node is current.
3248 - Supply a stack trace if the Taskmaster catches an exception.
3250 - When using a temporary file for a long link line on Win32 systems,
3251 (also) print the command line that is being executed through the
3254 - Initialize the LIB environment variable when using the Intel
3257 - Documentation fixes: better explain the AlwaysBuild() function.
3259 From Laurent Pelecq:
3261 - When the -debug=pdb option is specified, use pdb.Pdb().runcall() to
3262 call pdb directly, don't call Python recursively.
3266 - Add support for a platform-independent CPPDEFINES variable.
3268 From Christoph Wiedemann:

3291 - Portability fixes for non-GNU versions of lex and yacc.
3295 - Fix handling of library prefixes when the subdirectory matches
3298 From Timothee Bessett:
3300 - Add an M4 Builder.
3304 - Use '.lnk' as the suffix on the temporary file for linking long
3305 command lines (necessary for the Phar Lap linkloc linker).
3307 - Save non-string Options values as their actual type.
3309 - Save Options string values that contain a single quote correctly.
3311 - Save any Options values that are changed from the default
3312 Environment values, not just ones changed on the command line or in
3315 - Make closing the Options file descriptor exception-safe.
3319 - SCons now enforces (with an error) that construction variables
3320 must have the same form as valid Python identifiers.
3322 - Fix man page bugs: remove duplicate AddPostAction() description;
3323 document no_import_lib; mention that CPPFLAGS does not contain

3329 copying and pasting its wrap_text() function directly.
3331 - Make the Script.Options() subclass match the underlying base class
3334 - When reporting a target is up to date, quote the target like make

3395 - Using MSVC long command-line linking when running Cygwin.
3397 - Portability fixes for a lot of tests.
3399 - Add a Value Node class for dependencies on in-core Python values.

3440 integration build interfaces.
3442 - Change the name of the Set{Build,Content}SignatureType() functions
3443 to {Target,Source}Signatures(). Deprecate the old names but support

3490 - Fix a number of tests that searched for a Fortran compiler using the
3491 external PATH instead of what SCons would use.
3493 - Fix the interaction of SideEffect() and BuildDir() so that (for
3494 example) PDB files get put correctly in a BuildDir().

3532 - Fix a bug when BuildDir(duplicate=0) is used and SConscript
3533 files are called from within other SConscript files.
3535 - Support (older) versions of Perforce which don't set the Windows
3540 RELEASE 0.12 - Thu, 27 Mar 2003 23:52:09 -0600
3544 - Added support for the Perforce source code management system.
3546 - Fix str(Node.FS) so that it returns a path relative to the calling
3547 SConscript file's directory, not the top-level directory.

3554 calling callable variables when strings are expanded.
3558 - Added an INSTALL construction variable that can be set to a function
3559 to control how the Install() and InstallAs() Builders install files.
3560 The default INSTALL function now copies, not links, files.
3562 - Remove deprecated features: the "name" argument to Builder objects,
3563 and the Environment.Update() method.
3565 - Add an Environment.SourceCode() method to support fetching files
3566 from source code systems. Add factory methods that create Builders

3578 - Add support for Tar and Zip files.
3580 - Better documentation of the different ways to export variables to a
3581 subsidiary SConscript file. Fix documentation bugs in a tools

3586 (e.g. ${SOURCES[2]}) when calculating the build signature of a
3589 - Don't silently swallow exceptions thrown by Scanners (or other
3590 exceptions while finding a node's dependent children).
3592 - Push files to CacheDir() before calling the superclass built()
3593 method (which may clear the build signature as part of clearing
3594 cached implicit dependencies, if the file has a source scanner).
3595 (Bug reported by Jeff Petkau.)
3597 - Raise an internal error if we attempt to push a file to CacheDir()
3598 with a build signature of None.
3600 - Add an explicit Exit() function for terminating early.
3602 - Change the documentation to correctly describe that the -f option
3603 doesn't change to the directory in which the specified file lives.
3605 - Support changing directories locally with SConscript directory
3606 path names relative to any SConstruct file specified with -f.
3607 This allows you to build in another directory by simply changing
3608 there and pointing at the SConstruct file in another directory.
3610 - Change the default SConscriptChdir() behavior to change to the
3611 SConscript directory while it's being read.
3613 - Fix an exception thrown when the -U option was used with no
3614 Default() target specified.

3655 taking additional actions before or after building specific targets.
3657 - Add support for the PharLap ETS tool chain.
3661 - Allow Python function Actions to specify a list of construction
3662 variables that should be included in the Action's signature.

3665 and suffix, even when using the GNU linker.
3666 (Bug reported by Neal Becker.)
3668 - Use DOS-standard CR-LF line endings in the scons.bat file.
3669 (Bug reported by Gary Ruben.)

3682 (Bug reported by Esa Ilari Vuokko.)
3684 - Clean up error messages from problems duplicating into read-only
3685 BuildDir directories or into read-only files.
3687 - Add a CommandAction.strfunction() method, and add an "env" argument
3688 to the FunctionAction.strfunction() method, so that all Action
3689 objects have strfunction() methods, and the functions for building
3690 and returning a string both take the same arguments.
3692 - Add support for new CacheDir() functionality to share derived files
3693 between builds, with related options --cache-disable, --cache-force,
3696 - Change the default behavior when no targets are specified to build
3697 everything in the current directory and below (like Make). This
3698 can be disabled by specifying Default(None) in an SConscript.
3700 - Revamp SCons installation to fix a case-sensitive installation
3701 on Win32 systems, and to add SCons-specific --standard-lib,
3702 --standalone-lib, and --version-lib options for easier user
3703 control of where the libraries get installed.
3705 - Fix the ability to directly import and use Platform and Tool modules
3706 that have been implicitly imported into an Environment().
3708 - Add support for allowing an embedding interface to annotate a node
3711 - Extend the SConscript() function to accept build_dir and duplicate
3712 keyword arguments that function like a BuildDir() call.
3716 - Fix the output of -c -n when directories are involved, so it
3721 - Use a different shared object suffix (.os) when using gcc so shared
3722 and static objects can exist side-by-side in the same directory.
3724 - Allow the same object files on Win32 to be linked into either
3725 shared or static libraries.
3727 - Cache implicit cache values when using --implicit-cache.

3746 what would have happened when the -n option is used.
3748 - Don't create duplicate source files in a BuildDir when the -n
3751 - Refactor the Scanner interface to eliminate unnecessary Scanner
3752 calls and make it easier to write efficient scanners.

3765 the subdirectory in which it lives. (Bug reported by Gerard Patel.)
3767 - Fix automatic deduction of a target file name when there are
3768 multiple source files specified; the target is now deduced from just
3769 the first source file in the list.
3771 - Documentation fixes: better initial explanation of SConscript files;
3772 fix a misformatted "table" in the StaticObject explanation.
3774 From Steven Knight and Steve Leblanc:

3785 - Clean up things found by PyChecker (mostly unnecessary imports).
3787 - Add a script to use HappyDoc to create HTML class documentation.
3791 - Make the Environment.get() method return None by default.
3795 - Add SetJobs() and GetJobs() methods to allow configuration of the
3796 number of default jobs (still overridden by -j).
3798 - Convert the .sconsign file format from ASCII to a pickled Python
3801 - Error message cleanups: Made consistent the format of error
3802 messages (now all start with "scons: ***") and warning messages (now
3803 all start with "scons: warning:"). Caught more cases with the "Do
3804 not know how to build" error message.
3806 - Added support for the MinGW tool chain.
3808 - Added a --debug=includes option.
3812 RELEASE 0.09 - Thu, 5 Dec 2002 04:48:25 -0600
3816 - Add a Prepend() method to Environments, to append values to
3817 the beginning of construction variables.
3821 - Add long command-line support to the "lib" Tool (Microsoft library
3826 - Allow $$ in a string to be passed through as $.
3828 - Support file names with odd characters in them.
3830 - Add support for construction variable substition on scanner
3831 directories (in CPPPATH, F77PATH, LIBPATH, etc.).
3833 From Charles Crain and Steven Knight:
3835 - Add Repository() functionality, including the -Y option.
3839 - Fix auto-deduction of target names so that deduced targets end
3840 up in the same subdirectory as the source.
3842 - Don't remove source files specified on the command line!
3844 - Suport the Intel Fortran Compiler (ifl.exe).
3846 - Supply an error message if there are no command-line or
3847 Default() targets specified.
3849 - Fix the ASPPCOM values for the GNU assembler.
3850 (Bug reported by Brett Polivka.)
3852 - Fix an exception thrown when a Default() directory was specified
3853 when using the -U option.
3855 - Issue a warning when -c can't remove a target.
3857 - Eliminate unnecessary Scanner calls by checking for the
3858 existence of a file before scanning it. (This adds a generic
3859 hook to check an arbitrary condition before scanning.)
3861 - Add explicit messages to tell when we're "Reading SConscript files
3862 ...," "done reading SConscript files," "Building targets," and
3863 "done building targets." Add a -Q option to supress these.
3865 - Add separate $SHOBJPREFIX and $SHOBJSUFFIX construction variables
3866 (by default, the same as $OBJPREFIX and $OBJSUFFIX).
3868 - Add Make-like error messages when asked to build a source file,
3869 and before trying to build a file that doesn't have all its source
3870 files (including when an invalid drive letter is used on WIN32).
3872 - Add an scons-local-{version} package (in both .tar.gz and .zip
3873 flavors) to help people who want to ship SCons as a stand-alone
3874 build tool in their software packages.
3876 - Prevent SCons from unlinking files in certain situations when
3877 the -n option is used.
3879 - Change the name of Tool/lib.py to Tool/mslib.py.
3881 From Steven Knight and Anthony Roach:
3883 - Man page: document the fact that Builder calls return Node objects.
3887 - Refactor option processing to use our own version of Greg Ward's
3888 Optik module, modified to run under Python 1.5.2.
3890 - Add a ParseConfig() command to modify an environment based on
3891 parsing output from a *-config command.
3895 - Fix interpretation of '#/../foo' on Win32 systems.
3899 - Fixed use of command lines with spaces in their arguments,
3900 and use of Nodes with spaces in their string representation.
3902 - Make access and modification times of files in a BuildDir match
3903 the source file, even when hard linking isn't available.
3905 - Make -U be case insensitive on Win32 systems.
3907 - Issue a warning and continue when finding a corrupt .sconsign file.
3909 - Fix using an alias as a dependency of a target so that if one of the
3910 alias' dependencies gets rebuilt, the resulting target will, too.
3912 - Fix differently ordered targets causing unnecessary rebuilds
3913 on case insensitive systems.
3915 - Use os.system() to execute external commands whenever the "env"
3916 utility is available, which is much faster than fork()/exec(),
3917 and fixes the -j option on several platforms.
3919 - Fix use of -j with multiple targets.
3921 - Add an Options() object for friendlier accomodation of command-
3924 - Add support for Microsoft VC++ precompiled header (.pch) files,
3925 debugger (.pdb) files, and resource (.rc) files.
3927 - Don't compute the $_CPPINCFLAGS, $_F77INCFLAGS, $_LIBFLAGS and
3928 $_LIBDIRFLAGS variables each time a command is executed, define
3929 them so they're computed only as needed. Add a new _concat
3930 function to the Environment that allows people to define their
3931 own similar variables.
3933 - Fix dependency scans when $LIBS is overridden.
3935 - Add EnsurePythonVersion() and EnsureSConsVersion() functions.
3937 - Fix the overly-verbose stack trace on ListBuilder build errors.
3939 - Add a SetContentSignatureType() function, allowing use of file
3940 timestamps instead of MD5 signatures.
3942 - Make -U and Default('source') fail gracefully.
3944 - Allow the File() and Dir() methods to take a path-name string as
3945 the starting directory, in addition to a Dir object.
3947 - Allow the command handler to be selected via the SPAWN, SHELL
3948 and ESCAPE construction variables.
3950 - Allow construction variables to be overridden when a Builder
3955 - Dynamically check for the existence of utilities with which to
3956 initialize Environments by default.
3960 RELEASE 0.08 - Mon, 15 Jul 2002 12:08:51 -0500
3964 - Fixed a bug with relative CPPPATH dirs when using BuildDir().
3965 (Bug reported by Bob Summerwill.)
3967 - Added a warnings framework and a --warn option to enable or
3970 - Make the C scanner warn users if files referenced by #include
3971 directives cannot be found and --warn=dependency is specified.
3973 - The BUILDERS construction variable should now be a dictionary
3974 that maps builder names to actions. Existing uses of lists,
3975 and the Builder name= keyword argument, generate warnings
3976 about use of deprecated features.
3978 - Removed the "shared" keyword argument from the Object and
3981 - Added separated StaticObject, SharedObject, StaticLibrary and
3982 SharedLibrary builders. Made Object and Library synonyms for
3983 StaticObject and StaticLibrary, respectively.
3985 - Add LIBS and LIBPATH dependencies for shared libraries.
3987 - Removed support for the prefix, suffix and src_suffix arguments
3988 to Builder() to be callable functions.
3990 - Fix handling file names with multiple dots.
3992 - Allow a build directory to be outside of the SConstruct tree.
3994 - Add a FindFile() function that searches for a file node with a
3997 - Add $CPPFLAGS to the shared-object command lines for g++ and gcc.
3999 From Charles Crain and Steven Knight:
4001 - Add a "tools=" keyword argument to Environment instantiation,
4002 and a separate Tools() method, for more flexible specification
4003 of tool-specific environment changes.
4007 - Add a "platform=" keyword argument to Environment instantiation,
4008 and a separate Platform() method, for more flexible specification
4009 of platform-specific environment changes.
4011 - Updated README instructions and setup.py code to catch an
4012 installation failure from not having distutils installed.
4014 - Add descriptions to the -H help text for -D, -u and -U so
4015 people can tell them apart.
4017 - Remove the old feature of automatically splitting strings
4018 of file names on white space.
4020 - Add a dependency Scanner for native Fortran "include" statements,
4021 using a new "F77PATH" construction variable.
4023 - Fix C #include scanning to detect file names with characters like
4026 - Add more specific version / build output to the -v option.
4028 - Add support for the GNU as, Microsoft masm, and nasm assemblers.
4030 - Allow the "target" argument to a Builder call to be omitted, in
4031 which case the target(s) are deduced from the source file(s) and the
4032 Builder's specified suffix.
4034 - Add a tar archive builder.
4036 - Add preliminary support for the OS/2 Platform, including the icc
4041 - Fix --implicit-cache if the scanner returns an empty list.
4045 - Add a "multi" keyword argument to Builder creation that specifies
4046 it's okay to call the builder multiple times for a target.
4048 - Set a "multi" on Aliases so multiple calls will append to an Alias.
4050 - Fix emitter functions' use of path names when using BuildDir or
4053 - Fix --implicit-cache causing redundant rebuilds when the header
4056 - Fix --implicit-cache when a file has no implicit dependencies and
4057 its source is generated.
4059 - Make the drive letters on Windows always be the same case, so that
4060 changes in the case of drive letters don't cause a rebuild.
4062 - Fall back to importing the SCons.TimeStamp module if the SCons.MD5
4063 module can't be imported.
4065 - Fix interrupt handling to guarantee that a single interrupt will
4066 halt SCons both when using -j and not.
4068 - Fix .sconsign signature storage so that output files of one build
4069 can be safely used as input files to another build.
4071 - Added a --debug=time option to print SCons execution times.
4073 - Print an error message if a file can't be unlinked before being
4074 built, rather than just silently terminating the build.
4076 - Add a SideEffect() method that can be used to tell the build
4077 engine that a given file is created as a side effect of building
4078 a target. A file can be specified as a side effect of more than
4079 one build comand, in which case the commands will not be executed
4082 - Significant performance gains from not using our own version of
4083 the inefficient stock os.path.splitext() method, caching source
4084 suffix computation, code cleanup in MultiStepBuilder.__call__(),
4085 and replicating some logic in scons_subst().
4087 - Add --implicit-deps-changed and --implicit-deps-unchanged options.
4089 - Add a GetLaunchDir() function.
4091 - Add a SetBuildSignatureType() function.
4095 - Add an Append() method to Environments, to append values to
4096 construction variables.
4098 - Change the name of Update() to Replace(). Keep Update() as a
4099 deprecated synonym, at least for now.
4101 From Terrel Shumway:
4103 - Use a $PYTHON construction variable, initialized to sys.executable,
4104 when using Python to build parts of the SCons packages.
4106 - Use sys.prefix, not sys.exec_prefix, to find pdb.py.
4110 RELEASE 0.07 - Thu, 2 May 2002 13:37:16 -0500
4114 - Changes to build SCons packages on IRIX (and other *NIces).
4116 - Don't create a directory Node when a file already exists there,
4119 - Add 'dirs' and 'names' keyword arguments to SConscript for
4120 easier specification of subsidiary SConscript files.
4124 - Internal cleanup of environment passing to function Actions.
4126 - Builders can now take arbitrary keyword arguments to create
4127 attributes to be passed to: command generator functions,
4128 FunctionAction functions, Builder emitter functions (below),
4129 and prefix/suffix generator functions (below).
4131 - Command generator functions can now return ANYTHING that can be
4132 converted into an Action (a function, a string, a CommandGenerator
4133 instance, even an ActionBase instance).
4135 - Actions now call get_contents() with the actual target and source
4136 nodes used for the build.
4138 - A new DictCmdGenerator class replaces CompositeBuilder to support
4139 more flexible Builder behavior internally.
4141 - Builders can now take an emitter= keyword argument. An emitter
4142 is a function that takes target, source, and env argument, then
4143 return a 2-tuple of (new sources, new targets). The emitter is
4144 called when the Builder is __call__'ed, allowing a user to modify
4145 source and target lists.
4147 - The prefix, suffix and src_suffix Builder arguments now take a
4148 callable as well a string. The callable is passed the Environment
4149 and any extra Builder keyword arguments and is expected to return
4150 the appropriate prefix or suffix.
4152 - CommandActions can now be a string, a list of command + argument
4153 strings, or a list of commands (strings or lists).
4155 - Added shared library support. The Object and Library Builders now
4156 take a "shared=1" keyword argument to specify that a shared object
4157 or shared library should be built. It is an error to try to build
4158 static objects into a shared library or vice versa.
4160 - Win32 support for .def files has been added. Added the Win32-specific
4161 construction variables $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
4162 $WIN32DLLPREFIX and $WIN32IMPLIBPREFIX. When building a .dll,
4163 the new construction variable $WIN32_INSERT_DEF, controls whether
4164 the appropriately-named .def file is inserted into the target
4165 list (if not already present). A .lib file is always added to
4166 a Library build if not present in the list of targets.
4168 - ListBuilder now passes all targets to the action, not just the first.
4170 - Fix so that -c now deletes generated yacc .h files.
4172 - Builder actions and emitter functions can now be initialized, through
4173 construction variables, to things other than strings.
4175 - Make top-relative '#/dir' lookups work like '#dir'.
4177 - Fix for relative CPPPATH directories in subsidiary SConscript files
4180 - Add a for_signature argument to command generators, so that
4181 generators that need to can return distinct values for the
4182 command signature and for executing the command.
4186 - Create a better scons.bat file from a py2bat.py script on the Python
4187 mailing list two years ago (modeled after pl2bat.pl).
4191 - Fix so that -c -n does *not* remove the targets!
4193 - Man page: Add a hierarchical libraries + Program example.
4195 - Support long MSVC linker command lines through a builder action
4196 that writes to a temporary file and uses the magic MSVC "link @file"
4197 argument syntax if the line is longer than 2K characters.
4199 - Fix F77 command-line options on Win32 (use /Fo instead of -o).
4201 - Use the same action to build from .c (lower case) and .C (upper
4202 case) files on case-insensitive systems like Win32.
4204 - Support building a PDF file directly from a TeX or LaTeX file
4205 using pdftex or pdflatex.
4207 - Add a -x option to runtest.py to specify the script being tested.
4208 A -X option indicates it's an executable, not a script to feed
4209 to the Python interpreter.
4211 - Add a Split() function (identical to SCons.Util.argmunge()) for use
4212 in the next release, when Builders will no longer automatically split
4213 strings on white space.
4217 - Add the SConscriptChdir() method.
4221 - Fix --debug=tree when used with directory targets.
4223 - Significant internal restructuring of Scanners and Taskmaster.
4225 - Added new --debug=dtree option.
4227 - Fixes for --profile option.
4229 - Performance improvement in construction variable substitution.
4231 - Implemented caching of content signatures, plus added --max-drift
4232 option to control caching.
4234 - Implemented caching of dependency signatures, enabled by new
4235 --implicit-cache option.
4237 - Added abspath construction variable modifier.
4239 - Added $SOURCE variable as a synonym for $SOURCES[0].
4241 - Write out .sconsign files on error or interrupt so intermediate
4242 build results are saved.
4244 - Change the -U option to -D. Make a new -U that builds just the
4245 targets from the local SConscript file.
4247 - Fixed use of sys.path so Python modules can be imported from
4248 the SConscript directory.
4250 - Fix for using Aliases with the -u, -U and -D options.
4252 - Fix so that Nodes can be passed to SConscript files.
4256 - Changes for official Debian packaging.
4260 RELEASE 0.06 - Thu, 28 Mar 2002 01:24:29 -0600
4264 - Fix command generators to expand construction variables.
4266 - Make FunctionAction arguments be Nodes, not strings.
4268 From Stephen Kennedy:
4270 - Performance: Use a dictionary, not a list, for a Node's parents.
4274 - Add .zip files to the packages we build.
4276 - Man page: document LIBS, fix a typo, document ARGUMENTS.
4278 - Added RANLIB and RANLIBFLAGS construction variables. Only use them
4279 in ARCOM if there's a "ranlib" program on the system.
4281 - Add a configurable CFILESUFFIX for the Builder of .l and .y files
4284 - Add a CXXFile Builder that turns .ll and .yy files into .cc files
4285 (configurable via a CXXFILESUFFIX construction variable).
4287 - Use the POSIX-standard lex -t flag, not the GNU-specific -o flag.
4288 (Bug reported by Russell Christensen.)
4290 - Fixed an exception when CPPPATH or LIBPATH is a null string.
4291 (Bug reported by Richard Kiss.)
4293 - Add a --profile=FILE option to make profiling SCons easier.
4295 - Modify the new DVI builder to create .dvi files from LaTeX (.ltx
4298 - Add support for Aliases (phony targets).
4300 - Add a WhereIs() method for searching for path names to executables.
4302 - Add PDF and PostScript document builders.
4304 - Add support for compiling Fortran programs from a variety of
4305 suffixes (a la GNU Make): .f, .F, .for, .FOR, .fpp and .FPP
4307 - Support a CPPFLAGS variable on all default commands that use the
4312 - Add support for the -U option.
4314 - Allow CPPPATH, LIBPATH and LIBS to be specified as white-space
4317 - Add a document builder to create .dvi files from TeX (.tex) files.
4321 - Fix: Construction variables with values of 0 were incorrectly
4324 - Support env['VAR'] to fetch construction variable values.
4326 - Man page: document Precious().
4330 RELEASE 0.05 - Thu, 21 Feb 2002 16:50:03 -0600
4334 - Set PROGSUFFIX to .exe under Cygwin.
4338 - Allow a library to specified as a command-line source file, not just
4339 in the LIBS construction variable.
4341 - Compensate for a bug in os.path.normpath() that returns '' for './'
4344 - More performance optimizations: cache #include lines from files,
4345 eliminate unnecessary calls.
4347 - If a prefix or suffix contains white space, treat the resulting
4348 concatenation as separate arguments.
4350 - Fix irregularities in the way we fetch DevStudio information from
4351 the Windows registry, and in our registry error handling.
4355 - Flush stdout after print so it intermixes correctly with stderr
4358 - Allow Scanners to return a list of strings, and document how to
4359 write your own Scanners.
4361 - Look up implicit (scanned) dependencies relative to the directory
4362 of file being scanned.
4364 - Make writing .sconsign files more robust by first trying to write
4365 to a temp file that gets renamed.
4367 - Create all of the directories for a list of targets before trying
4368 to build any of the targets.
4370 - WIN32 portability fixes in tests.
4372 - Allow the list of variables exported to an SConscript file to be
4375 - Document the overlooked LIBPATH construction variable.
4376 (Bug reported by Eicke Godehardt.)
4378 - Fix so that Ignore() ignores indirect, implicit dependencies
4379 (included files), not just direct dependencies.
4381 - Put the man page in the Debian distribution.
4383 - Run HTML docs through tidy to clean up the HTML (for Konqueror).
4385 - Add preliminary support for Unicode strings.
4387 - Efficiency: don't scan dependencies more than once during the
4390 - Fix the -c option so it doesn't stop removing targets if one doesn't
4392 (Bug reported by Paul Connell.)
4394 - Fix the --debug=pdb option when run on Windows NT.
4395 (Bug reported by Paul Connell.)
4397 - Add support for the -q option.
4401 - Add support for the -u option.
4403 - Add .cc and .hh file suffixes to the C Scanner.
4407 - Make the scons script return an error code on failures.
4409 - Add support for using code to generate a command to build a target.
4413 RELEASE 0.04 - Wed, 30 Jan 2002 11:09:42 -0600
4417 - Significant performance improvements in the Node.FS and
4420 - Fix signatures of binary files on Win32 systems.
4422 - Allow LIBS and LIBPATH to be strings, not just arrays.
4424 - Print a traceback if a Python-function builder throws an exception.
4428 - Fix using a directory as a Default(), and allow Default() to
4429 support white space in file names for strings in arrays.
4431 - Man page updates: corrected some mistakes, documented various
4432 missing Environment methods, alphabetized the construction
4433 variables and other functions, defined begin and end macros for
4434 the example sections, regularized white space separation, fixed
4435 the use of Export() in the Multiple Variants example.
4437 - Function action fixes: None is now a successful return value.
4438 Exceptions are now reported. Document function actions.
4440 - Add 'Action' and 'Scanner' to the global keywords so SConscript
4441 files can use them too.
4443 - Removed the Wrapper class between Nodes and Walkers.
4445 - Add examples using Library, LIBS, and LIBPATH.
4447 - The C Scanner now always returns a sorted list of dependencies
4448 so order changes don't cause unnecessary rebuilds.
4450 - Strip $(-$) bracketed text from command lines. Use this to
4451 surround $_INCDIRS and $_LIBDIRS so we don't rebuild in response
4452 to changes to -I or -L options.
4454 - Add the Ignore() method to ignore dependencies.
4456 - Provide an error message when a nonexistent target is specified
4457 on the command line.
4459 - Remove targets before building them, and add an Environment
4460 Precious() method to override that.
4462 - Eliminate redundant calls to the same builder when the target is a
4463 list of targets: Add a ListBuilder class that wraps Builders to
4464 handle lists atomically. Extend the Task class to support building
4465 and updating multiple targets in a single Task. Simplify the
4466 interface between Task and Taskmaster.
4468 - Add a --debug=pdb option to re-run SCons under the Python debugger.
4470 - Only compute a build signature once for each node.
4472 - Changes to our sys.path[] manipulation to support installation into
4473 an arbitrary --prefix value.
4477 - Add var=value command-line arguments.
4481 RELEASE 0.03 - Fri, 11 Jan 2002 01:09:30 -0600
4485 - Performance improvements in the Node.FS and Sig.Calculator classes.
4487 - Add the InstallAs() method.
4489 - Execute commands through an external interpreter (sh, cmd.exe, or
4490 command.com) to handle redirection metacharacters.
4492 - Allow the user to supply a command handler.
4496 - Search both /usr/lib and /usr/local/lib for scons directories by
4497 adding them both to sys.path, with whichever is in sys.prefix first.
4499 - Fix interpreting strings of multiple white-space separated file names
4500 as separate file names, allowing prefixes and suffixes to be appended
4501 to each individually.
4503 - Refactor to move CompositeBuilder initialization logic from the
4504 factory wrapper to the __init__() method, and allow a Builder to
4505 have both an action and a src_builder (or array of them).
4507 - Refactor BuilderBase.__call__() to separate Node creation/lookup
4508 from initialization of the Node's builder information.
4510 - Add a CFile Builder object that supports turning lex (.l) and
4511 yacc (.y) files into .c files.
4513 - Document: variable interpretation attributes; how to propogate
4514 the user's environment variables to executed commands; how to
4515 build variants in multiple BuildDirs.
4517 - Collect String, Dict, and List type-checking in common utility
4518 routines so we can accept User{String,Dict,List}s all over.
4520 - Put the Action factory and classes into their own module.
4522 - Use one CPlusPlusAction in the Object Builder's action dictionary,
4523 instead of letting it create multiple identical instances.
4525 - Document the Install() and InstallAs() methods.
4529 - Require that a Builder be given a name argument, supplying a
4530 useful error message when it isn't.
4534 - Add a "duplicate" keyword argument to BuildDir() that can be set
4535 to prevent linking/copying source files into build directories.
4537 - Add a "--debug=tree" option to print an ASCII dependency tree.
4539 - Fetch the location of the Microsoft Visual C++ compiler(s) from
4540 the Registry, instead of hard-coding the location.
4542 - Made Scanner objects take Nodes, not path names.
4544 - Have the C Scanner cache the #include file names instead of
4545 (re-)scanning the file each time it's called.
4547 - Created a separate class for parent "nodes" of file system roots,
4548 eliminating the need for separate is-parent-null checks everywhere.
4550 - Removed defined __hash__() and __cmp() methods from FS.Entry, in
4551 favor of Python's more efficient built-in identity comparisons.
4555 RELEASE 0.02 - Sun, 23 Dec 2001 19:05:09 -0600
4559 - Added the Install(), BuildDir(), and Export() methods.
4561 - Fix the -C option by delaying setting the top of the FS tree.
4563 - Avoid putting the directory path on the libraries in the LIBS
4564 construction variable.
4566 - Added a GetBuildPath() method to return the full path to the
