Changelog:
SCons - a software construction tool
Change Log
RELEASE 2.5.1 - Mon, 03 Nov 2016 13:37:42 -0400
From William Deegan:
- Add scons-configure-cache.py to packaging. It was omitted
From Alexey Klimkin:
- Use memoization to optimize PATH evaluation across all dependencies
per
node. (PR #345)
RELEASE 2.5.0 - Mon, 09 Apr 2016 11:27:42 -0700
From Dirk Baechle:
- Removed a lot of compatibility methods and workarounds
for Python versions < 2.7, in order to prepare the work
towards a combined 2.7/3.x version. (PR #284)
Also fixed the default arguments for the print_tree and
render_tree methods. (PR #284, too)
From William Blevins:
- Added support for cross-language dependency scanning;
SCons now respects scanner keys for implicit dependencies.
- Notes for SCons users with heterogeneous systems.
- May find new (previously missed) dependencies.
- May cause rebuild after upgrade due to dependency changes.
- May find new dependency errors (EG. cycles).
- Discovered in some of the SCons QT tests.
- Resolved missing cross-language dependencies for
SWIG bindings (fixes #2264).
- Corrected typo in User Guide for Scanner keyword. (PR #2959)
- Install builder interacts with scanner found in SCANNERS differently.
- Previous: Install builder recursively scanned implicit dependencies
for scanners from SCANNER, but not for built-in (default) scanners.
- Current: Install builder will not scan for implicit dependencies via
either scanner source. This optimizes some Install builder behavior
and brings orthogonality to Install builder scanning behavior.
From William Deegan:
- Add better messaging when two environments have
different actions for the same target (Bug #2024)
- Fix issue only with MSVC and Always build where targets
marked AlwaysBuild wouldn't make it into CHANGED_SOURCES
and thus yield an empty compile command line. (Bug #2622)
- Fix posix platform escaping logic to properly handle paths
with parens in them "()". (Bug #2225)
From Jakub Pola:
- Intel Compiler 2016 (Linux/Mac) update for tool directories.
From Adarsh Sanjeev:
- Fix for issue #2494: Added string support for Chmod function.
From Tom Tanner:
- change cache to use 2 character subdirectories, rather than one
character,
so as not to give huge directories for large caches, a situation which
causes issues for NFS.
For existing caches, you will need to run the scons-configure-cache.py
script to update them to the new format. You will get a warning every
time
you build until you co this.
- Fix a bunch of unit tests on windows
RELEASE 2.4.1 - Mon, 07 Nov 2015 10:37:21 -0700
From Arfrever Frehtes Taifersar Arahesis:
- Fix for Bug # 2791 - Setup.py fails unnecessarily under Jython.
From Dirk Baechle:
- Fixed license of SVG titlepage files in the context of Debian
packaging, such that they allow for commercial use too (#2985).
From William Blevins:
- InstallVersionedLib now available in the DefaultEnvironment context.
- Improves orthogonality of use cases between different Install
functions.
From Carnë Draug:
- Added new configure check, CheckProg, to check for
existence of a program.
From Andrew Featherstone:
- Fix for issue #2840 - Fix for two environments specifying same target
with different
actions not throwing hard error. Instead SCons was incorrectly
issuing a warning
and continuing.
From Hiroaki Itoh :
- Add support `Microsoft Visual C++ Compiler for Python 2.7'
Compiler can be obtained at:
https://www.microsoft.com/en-us/download/details.aspx?id=44266
From Florian Miedniak:
- Fixed tigris issue #3011: Glob() excludes didn't work when used with
VariantDir(duplicate=0)
From William Roberts:
- Fix bug 2831 and allow Help() text to be appended to AddOption() help.
From Paweł Tomulik:
- Reimplemented versioning for shared libraries, with the following
effects
- Fixed tigris issues #3001, #3006.
- Fixed several other issues not reported to tigris, including:
issues with versioned libraries in subdirectories with tricky names,
issues with versioned libraries and variant directories,
issue with soname not being injected to library when using D linkers,
- Switched to direct symlinks instead of daisy-chained ones -- soname
and
development symlinks point directly to the versioned shared library
now),
for rationale see:
https://www.debian.org/doc/debian-policy/ch-sharedlibs.html
https://fedoraproject.org/wiki/Packaging:Guidelines#Devel_Packages
https://bitbucket.org/scons/scons/pull-requests/247/new-versioned-libraries-gnulink-cyglink/diff#comment-10063929
- New construction variables to allow override default behavior: SONAME,
SHLIBVERSIONFLAGS, _SHLIBVERSIONFLAGS, SHLIBNOVERSIONSYMLINKS,
LDMODULEVERSION, LDMODULEVERSIONFLAGS, _LDMODULEVERSIONFLAGS,
LDMODULENOVERSIONSYMLINKS.
- Changed logic used to configure the versioning machinery from
platform-centric to linker-oriented.
- The SHLIBVERSION/LDMODULEVERSION variables are no longer validated by
SCons (more freedom to users).
- InstallVersionedLib() doesn't use SHLIBVERSION anymore.
- Enchanced docs for the library versioning stuff.
- New tests for versioned libraries.
- Library versioning is currently implemented for the following linker
tools: 'cyglink', 'gnulink', 'sunlink'.
- Fix to swig tool - pick-up 'swig', 'swig3.0' and 'swig2.0' (in order).
- Fix to swig tool - respect env['SWIG'] provided by user.
RELEASE 2.4.0 - Mon, 21 Sep 2015 08:56:00 -0700
From Dirk Baechle:
- Switched several core classes to use "slots", to
reduce the overall memory consumption in large
projects (fixes #2180, #2178, #2198)
- Memoizer counting uses decorators now, instead of
the old metaclasses approach.

construction variable MSVS_SCC_PROJECT_BASE_PATH, which never
worked properly, is removed. Users can use the new variable
MSVS_SCC_CONNECTION_ROOT instead if desired.
From Anatoly Techtonik:
- Use subprocess in bootstrap.py instead of os.execve to avoid
losing output control on Windows (http://bugs.python.org/issue9148)
- Revert patch for adding SCons to App Paths, because standard cmd
shell doesn't search there. This is confusing, because `scons` can
be executed from explorer, but fail to start from console.

- Updated the TeX command strings to include a /D on Windows in
case the new directory is on a different drive letter.
- Fixed the LaTeX scanner so dependencies are found in commands that

searching to find the correct file. Thanks to Lennart Sauerbeck
for the test case and initial patch
Also allow the \include of files in subdirectories when variantDir
is used with duplicate=0. Previously latex would crash since
the directory in which the .aux file is written was not created.
Thanks to Stefan Hepp for finding this and part of the solution.
From James Teh:
- Patches to fix some issues using MS SDK V7.0
From William Deegan:
- Lots of testing and minor patches to handle mixed MS VC and SDK
installations, as well as having only the SDK installed.

Latex output
- Remove LATEXSUFFIXES from environments that don't initialize Tex.
- Add support for the glossaries package for glossaries and acronyms

From Jared Grubb:
- Fix VariantDir duplication of #included files in subdirectories.
From Ludwig H�hne:
- Reduce memory usage when a directory is used as a dependency of
another Node (such as an Alias) by returning a concatenation
of the children's signatures + names, not the children's contents,
as the directory contents.

closures in Python versions before 2.5.
From David Cournapeau:
- Fix the initialization of $SHF77FLAGS so it includes $F77FLAGS.
From Jonas Olsson:
- Fix a syntax error in the Intel C compiler support on Windows.
From Steven Knight:
- Change how we represent Python Value Nodes when printing and when
stored in .sconsign files (to avoid blowing out memory by storing
huge strings in .sconsign files after multiple runs using Configure
contexts cause the Value strings to be re-escaped each time).
- Fix a regression in not executing configuration checks after failure
of any configuration check that used the same compiler or other tool.
- Handle multiple destinations in Visual Studio 8 settings for the
analogues to the INCLUDE, LIBRARY and PATH variables.

"import SCons.Options.{Bool,Enum,List,Package,Path}Option" submodules.
- Fix searching for implicit dependencies when an Entry Node shows up
in the search path list.
From Stefano:
- Fix expansion of $FORTRANMODDIR in the default Fortran command line(s)

From Johan Boul�:
- Fix the ability to use LoadableModule() under MinGW.
From David Cournapeau:
- Various missing Fortran-related construction variables have been added.
- SCons now uses the program specified in the $FORTRAN construction
variable to link Fortran object files.
- Fortran compilers on Linux (Intel, g77 and gfortran) now add the -fPIC
option by default when compilling shared objects.
- New 'sunf77', 'sunf90' and 'sunf95' Tool modules have been added to
support Sun Fortran compilers. On Solaris, the Sun Fortran compilers
are used in preference to other compilers by default.
- Fortran support now uses gfortran in preference to g77.
- Fortran file suffixes are now configurable through the
$F77FILESUFFIXES, $F90FILESUFFIXES, $F95FILESUFFIXES and
$FORTRANFILESUFFIXES variables.
From Steven Knight:
- Make the -d, -e, -w and --no-print-directory options "Ignored for
compatibility." (We're not going to implement them.)
- Fix a serious inefficiency in how SCons checks for whether any source
files are missing when a Builder call creates many targets from many
input source files.
- In Java projects, make the target .class files depend only on the
specific source .java files where the individual classes are defined.
- Don't store duplicate source file entries in the .sconsign file so
we don't endlessly rebuild the target(s) for no reason.
- Add a Variables object as the first step towards deprecating the
Options object name. Similarly, add BoolVariable(), EnumVariable(),
ListVariable(), PackageVariable() and PathVariable() functions
as first steps towards replacing BoolOption(), EnumOption(),
ListOption(), PackageOption() and PathOption().
- Change the options= keyword argument to the Environment() function
to variables=, to avoid confusion with SCons command-line options.
Continue supporting the options= keyword for backwards compatibility.
- When $SWIGFLAGS contains the -python flag, expect the generated .py
file to be in the same (sub)directory as the target.
- When compiling C++ files, allow $CCFLAGS settings to show up on the
command line even when $CXXFLAGS has been redefined.
- Fix --interactive with -u/-U/-D when a VariantDir() is used.
From Anatoly Techtonik:
- Have the scons.bat file add the script execution directory to its

a later top-level target depends on a child that failed its build.
- Fix being able to use $PDB and $WINDWOWS_INSERT_MANIFEST together.
- Don't crash if un-installing the Intel C compiler leaves left-over,
dangling entries in the Windows registry.
- Improve support for non-standard library prefixes and suffixes by
stripping all prefixes/suffixes from file name string as appropriate.
- Reduce the default stack size for -j worker threads to 256 Kbytes.
Provide user control over this value by adding --stack-size and
--warn=stack-size options, and a SetOption('stack_size') function.
- Fix a crash on Linux systems when trying to use the Intel C compiler
and no /opt/intel_cc_* directories are found.
- Improve using Python functions as actions by incorporating into
a FunctionAction's signature:
- literal values referenced by the byte code.
- values of default arguments
- code of nested functions
- values of variables captured by closures
- names of referenced global variables and functions
- Fix the closing message when --clean and --keep-going are both
used and no errors occur.
- Add support for the Intel C compiler on Mac OS X.
- Speed up reading SConscript files by about 20% (for some
configurations) by: 1) optimizing the SCons.Util.is_*() and
SCons.Util.flatten() functions; 2) avoiding unnecessary os.stat()
calls by using a File's .suffix attribute directly instead of
stringifying it.
From Jérôme Berger:
- Have the D language scanner search for .di files as well as .d files.
- Add a find_include_names() method to the Scanner.Classic class to
abstract out how included names can be generated by subclasses.

a single statement.
From Konstantin Bozhikov:
- Support expansion of construction variables that contain or refer
to lists of other variables or Nodes within expansions like $CPPPATH.
- Change variable substitution (the env.subst() method) so that an
input sequence (list or tuple) is preserved as a list in the output.
From David Cournapeau:
- Add a CheckDeclaration() call to configure contexts.
- Improve the CheckTypeSize() code.
- Add a Define() call to configure contexts, to add arbitrary #define
lines to a generated configure header file.
- Add a "gfortran" Tool module for the GNU F95/F2003 compiler.
- Avoid use of -rpath with the Mac OS X linker.
- Add comment lines to the generated config.h file to describe what
the various #define/#undef lines are doing.
From Steven Knight:
- Support the ability to subclass the new-style "str" class as input
to Builders.
- Improve the performance of our type-checking by using isinstance()
with new-style classes.
- Fix #include (and other $*PATH variables searches) of files with
absolute path names. Don't die if they don't exist (due to being
#ifdef'ed out or the like).
- Fix --interactive mode when Default(None) is used.
- Fix --debug=memoizer to work around a bug in base Python 2.2 metaclass
initialization (by just not allowing Memoization in Python versions
that have the bug).
- Have the "scons-time time" subcommand handle empty log files, and
log files that contain no results specified by the --which option.
- Fix the max Y of vertical bars drawn by "scons-time --fmt=gnuplot".
- On Mac OS X, account for the fact that the header file generated
from a C++ file will be named (e.g.) file.cpp.h, not file.hpp.
- Fix floating-point numbers confusing the Java parser about
generated .class file names in some configurations.
- Document (nearly) all the values you can now fetch with GetOption().
- Fix use of file names containing strings of multiple spaces when
using ActionFactory instances like the Copy() or Move() function.
- Fix a 0.97 regression when using a variable expansion (like
$OBJSUFFIX) in a source file name to a builder with attached source
builders that match suffix (like Program()+Object()).
- Have the Java parser recognize generics (surrounded by angle brackets)
so they don't interfere with identifying anonymous inner classes.
- Avoid an infinite loop when trying to use saved copies of the
env.Install() or env.InstallAs() after replacing the method
attributes.

- Add a warning about env.Copy() being deprecated.
- Add warnings about the --debug={dtree,stree,tree} options
being deprecated.
- Add VariantDir() as the first step towards deprecating BuildDir().
Add the keyword argument "variant_dir" as the replacement for
"build_dir".

functions being deprecated.
From Rob Managan:
- Enhance TeX and LaTeX support to work with BuildDir(duplicate=0).
- Re-run LaTeX when it issues a package warning that it must be re-run.
From Leanid Nazdrynau:
- Have the Copy() action factory preserve file modes and times
when copying individual files.
From Jan Nijtmans:
- If $JARCHDIR isn't set explicitly, use the .java_classdir attribute
that was set when the Java() Builder built the .class files.
From Greg Noel:
- Document the Dir(), File() and Entry() methods of Dir and File Nodes.
- Add the parse_flags option when creating Environments
From Gary Oberbrunner:
- Make File(), Dir() and Entry() return a list of Nodes when passed
a list of names, instead of trying to make a string from the name
list and making a Node from that string.
- Fix the ability to build an Alias in --interactive mode.
- Fix the ability to hash the contents of actions for nested Python
functions on Python versions where the inability to pickle them
returns a TypeError (instead of the documented PicklingError).
From Jonas Olsson:
- Fix use of the Intel C compiler when the top compiler directory,
but not the compiler version, is specified.
- Handle Intel C compiler network license files (port at system).
From Jim Randall:
- Fix how Python Value Nodes are printed in --debug=explain output.

cleaning) targets without re-reading the SConscript files every time.
- Fix use of readline command-line editing in --interactive mode.

versions where all() is a builtin function.
From Daniel Svensson:
- Code correction in SCons.Util.is_List().

RELEASE 0.97.0d20071212 - Wed, 12 Dec 2007 09:29:32 -0600
From Benoit Belley:
- Fix occasional spurious rebuilds and inefficiency when using
--implicit-cache and Builders that produce multiple targets.
- Allow SCons to not have to know about the builders of generated
files when BuildDir(duplicate=0) is used, potentially allowing some
SConscript files to be ignored for smaller builds.
From David Cournapeau:
- Add a CheckTypeSize() call to configure contexts.
From Ken Deeter:
- Make the "contents" of Alias Nodes a concatenation of the children's
content signatures (MD5 checksums), not a concatenation of the
children's contents, to avoid using large amounts of memory during
signature calculation.
From Malte Helmert:
- Fix a lot of typos in the man page and User's Guide.
From Geoffrey Irving:
- Speed up conversion of paths in .sconsign files to File or Dir Nodes.
From Steven Knight:
- Add an Options.UnknownOptions() method that returns any settings
(from the command line, or whatever dictionary was passed in)
that aren't known to the Options object.
- Add a Glob() function.
- When removing targets with the -c option, use the absolute path (to
avoid problems interpreting BuildDir() when the top-level directory
is the source directory).
- Fix problems with Install() and InstallAs() when called through a
clone (of a clone, ...) of a cloned construction environment.
- When executing a file containing Options() settings, add the file's
directory to sys.path (so modules can be imported from there) and
explicity set __name__ to the name of the file so the statement's
in the file can deduce the location if they need to.
- Fix an O(n^2) performance problem when adding sources to a target
through calls to a multi Builder (including Aliases).
- Redefine the $WINDOWSPROGMANIFESTSUFFIX and
$WINDOWSSHLIBMANIFESTSUFFIX variables so they pick up changes to
the underlying $SHLIBSUFFIX and $PROGSUFFIX variables.
- Add a GetBuildFailures() function that can be called from functions
registered with the Python atexit module to print summary information
about any failures encountered while building.
- Return a NodeList object, not a Python list, when a single_source
Builder like Object() is called with more than one file.
- When searching for implicit dependency files in the directories
in a $*PATH list, don't create Dir Nodes for directories that
don't actually exist on-disk.
- Add a Requires() function to allow the specification of order-only
prerequisites, which will be updated before specified "downstream"
targets but which don't actually cause the target to be rebuilt.
- Restore the FS.{Dir,File,Entry}.rel_path() method.
- Make the default behavior of {Source,Target}Signatures('timestamp')
be equivalent to 'timestamp-match', not 'timestamp-newer'.
- Fix use of CacheDir with Decider('timestamp-newer') by updating
the modification time when copying files from the cache.
- Fix random issues with parallel (-j) builds on Windows when Python
holds open file handles (especially for SCons temporary files,
or targets built by Python function actions) across process creation.
From Maxim Kartashev:
- Fix test scripts when run on Solaris.
From Gary Oberbrunner:
- Fix Glob() when a pattern is in an explicitly-named subdirectory.
From Philipp Scholl:
- Fix setting up targets if multiple Package builders are specified
at once.
RELEASE 0.97.0d20070918 - Tue, 18 Sep 2007 10:51:27 -0500
From Steven Knight:
- Fix the wix Tool module to handle null entries in $PATH variables.
- Move the documentation of Install() and InstallAs() from the list
of functions to the list of Builders (now that they're implemented
as such).
- Allow env.CacheDir() to be set per construction environment. The
global CacheDir() function now sets an overridable global default.
- Add an env.Decider() method and a Node.Decider() method that allow
flexible specification of an arbitrary function to decide if a given
dependency has changed since the last time a target was built.
- Don't execute Configure actions (while reading SConscript files)
when cleaning (-c) or getting help (-h or -H).
- Add to each target an implicit dependency on the external command(s)
used to build the target, as found by searching env['ENV']['PATH']
for the first argument on each executed command line.
- Add support for a $IMPLICIT_COMMAND_DEPENDENCIES construction
variabe that can be used to disable the automatic implicit
dependency on executed commands.
- Add an "ensure_suffix" keyword to Builder() definitions that, when
true, will add the configured suffix to the targets even if it looks
like they already have a different suffix.
- Add a Progress() function that allows for calling a function or string
(or list of strings) to display progress while walking the DAG.
- Allow ParseConfig(), MergeFlags() and ParseFlags() to handle output
from a *config command with quoted path names that contain spaces.
- Make the Return() function stop processing the SConscript file and
return immediately. Add a "stop=" keyword argument that can be set
to False to preserve the old behavior.
- Fix use of exitstatfunc on an Action.
- Introduce all man page function examples with "Example:" or "Examples:".
- When a file gets added to a directory, make sure the directory gets
re-scanned for the new implicit dependency.
- Fix handling a file that's specified multiple times in a target
list so that it doesn't cause dependent Nodes to "disappear" from
the dependency graph walk.
From Carsten Koch:
- Avoid race conditions with same-named files and directory creation
when pushing copies of files to CacheDir().
From Tzvetan Mikov:
- Handle $ in Java class names.
From Gary Oberbrunner:
- Add support for the Intel C compiler on Windows64.
- On SGI IRIX, have $SHCXX use $CXX by default (like other platforms).
From Sohail Somani:
- When Cloning a construction environment, set any variables before
applying tools (so the tool module can access the configured settings)
and re-set them after (so they end up matching what the user set).
From Matthias Troffaes:
- Make sure extra auxiliary files generated by some LaTeX packages
and not ending in .aux also get deleted by scons -c.
From Greg Ward:
- Add a $JAVABOOTCLASSPATH variable for directories to be passed to the
javac -bootclasspath option.
From Christoph Wiedemann:
- Add implicit dependencies on the commands used to build a target.
RELEASE 0.97.0d20070809 - Fri, 10 Aug 2007 10:51:27 -0500
From Lars Albertsson:
- Don't error if a #include line happens to match a directory
somewhere on a path (like $CPPPATH, $FORTRANPATH, etc.).
From Mark Bertoglio:
- Fix listing multiple projects in Visual Studio 7.[01] solution files,
including generating individual project GUIDs instead of re-using
the solution GUID.
From Jean Brouwers:
- Add /opt/SUNWspro/bin to the default execution PATH on Solaris.
From Allan Erskine:
- Only expect the Microsoft IDL compiler to emit *_p.c and *_data.c
files if the /proxy and /dlldata switches are used (respectively).
From Steven Knight:
- Have --debug=explain report if a target is being rebuilt because
AlwaysBuild() is specified (instead of "unknown reasons").
- Support {Get,Set}Option('help') to make it easier for SConscript
files to tell if a help option (-h, --help, etc.) has been specified.
- Support {Get,Set}Option('random') so random-dependency interaction
with CacheDir() is controllable from SConscript files.
- Add a new AddOption() function to support user-defined command-
line flags (like --prefix=, --force, etc.).
- Replace modified Optik version with new optparse compatibility module
for command line processing in Scripts/SConsOptions.py
- Push and retrieve built symlinks to/from a CacheDir() as actual
symlinks, not by copying the file contents.
- Fix how the Action module handles stringifying the shared library
generator in the Tool/mingw.py module.
- When generating a config.h file, print "#define HAVE_{FEATURE} 1"
instad of just "#define HAVE_{FEATURE}", for more compatibility
with Autoconf-style projects.
- Fix expansion of $TARGET, $TARGETS, $SOURCE and $SOURCES keywords in
Visual C/C++ PDB file names.
- Fix locating Visual C/C++ PDB files in build directories.
- Support an env.AddMethod() method and an AddMethod() global function
for adding a new method, respectively, to a construction environment
or an arbitrary object (such as a class).
- Fix the --debug=time option when the -j option is specified and all
files are up to date.
- Add a $SWIGOUTDIR variable to allow setting the swig -outdir option,
and use it to identify files created by the swig -java option.
- Add a $SWIGPATH variable that specifies the path to be searched
for included SWIG files, Also add related $SWIGINCPREFIX and
$SWIGINCSUFFIX variables that specify the prefix and suffix to
be be added to each $SWIGPATH directory when expanded on the SWIG
command line.
- More efficient copying of construction environments (mostly borrowed
from copy.deepcopy() in the standard Python library).
- When printing --tree=prune output, don't print [brackets] around
source files, only do so for built targets with children.
- Fix interpretation of Builder source arguments when the Builder has
a src_suffix *and* a source_builder and the argument has no suffix.
- Fix use of expansions like ${TARGET.dir} or ${SOURCE.dir} in the
following construction variables: $FORTRANMODDIR, $JARCHDIR,
$JARFLAGS, $LEXFLAGS, $SWIGFLAGS, $SWIGOUTDIR and $YACCFLAGS.
- Fix dependencies on Java files generated by SWIG so they can be
detected and built in one pass.
- Fix SWIG when used with a BuildDir().
From Leanid Nazdrynau:
- When applying Tool modules after a construction environment has
already been created, don't overwrite existing $CFILESUFFIX and
$CXXFILESUFFIX value.
- Support passing the Java() builder a list of explicit .java files
(not only a list of directories to be scanned for .java files).
- Support passing .java files to the Jar() and JavaH() builders, which
then use the builder underlying the Java() builder to turn them into
.class files. (That is, the Jar()-Java() chain of builders become
multi-step, like the Program()-Object()-CFile() builders.)
- Support passing SWIG .i files to the Java builders (Java(),
Jar(), JavaH()), to cause intermediate .java files to be created
automatically.
- Add $JAVACLASSPATH and $JAVASOURCEPATH variables, that get added to
the javac "-classpath" and "-sourcepath" options. (Note that SCons
does *not* currently search these paths for implicit dependencies.)
- Commonize initialization of Java-related builders.
From Jan Nijtmans:
- Find Java anonymous classes when the next token after the name is
an open parenthesis.
From Gary Oberbrunner:
- Fix a code example in the man page.
From Tilo Prutz:
- Add support for the file names that Java 1.5 (and 1.6) generates for
nested anonymous inner classes, which are different from Java 1.4.
From Adam Simpkins:
- Allow worker threads to terminate gracefully when all jobs are
finished.
From Sohail Somani:
- Add LaTeX scanner support for finding dependencies specified with
the \usepackage{} directive.
RELEASE 0.97 - Thu, 17 May 2007 08:59:41 -0500
From Steven Knight:
- Fix a bug that would make parallel builds stop in their tracks if
Nodes that depended on lists that contained some Nodes built together
caused the reference count to drop below 0 if the Nodes were visited
and commands finished in the wrong order.
- Make sure the DirEntryScanner doesn't choke if it's handed something
that's not a directory (Node.FS.Dir) Node.
RELEASE 0.96.96 - Thu, 12 Apr 2007 12:36:25 -0500
NOTE: This is (Yet) a(nother) pre-release of 0.97 for testing purposes.
From Joe Bloggs:
- Man page fix: remove cut-and-paste sentence in NoCache() description.
From Dmitry Grigorenko and Gary Oberbrunner:
- Use the Intel C++ compiler, not $CC, to link C++ source.
From Helmut Grohne:
- Fix the man page example of propagating a user's external environment.
From Steven Knight:
- Back out (most of) the Windows registry installer patch, which
seems to not work on some versions of Windows.
- Don't treat Java ".class" attributes as defining an inner class.
- Fix detecting an erroneous Java anonymous class when the first
non-skipped token after a "new" keyword is a closing brace.
- Fix a regression when a CPPDEFINES list contains a tuple, the second
item of which (the option value) is a construction variable expansion
(e.g. $VALUE) and the value of the variable isn't a string.
- Improve the error message if an IOError (like trying to read a
directory as a file) occurs while deciding if a node is up-to-date.
- Fix "maximum recursion" / "unhashable type" errors in $CPPPATH
PathList expansion if a subsidiary expansion yields a stringable,
non-Node object.
- Generate API documentation from the docstrings (using epydoc).
- Fix use of --debug=presub with Actions for out-of-the-box Builders.
- Fix handling nested lists within $CPPPATH, $LIBPATH, etc.
- Fix a "builders_used" AttributeError that real-world Qt initialization
triggered in the refactored suffix handling for Builders.
- Make the reported --debug=time timings meaningful when used with -j.
Better documentation of what the times mean.
- User Guide updates: --random, AlwaysBuild(), --tree=,
--debug=findlibs, --debug=presub, --debug=stacktrace,
--taskmastertrace.
- Document (in both man page and User's Guide) that --implicit-cache
ignores changes in $CPPPATH, $LIBPATH, etc.
From Jean-Baptiste Lab:
- Remove hard-coded dependency on Python 2.2 from Debian packaging files.
From Jeff Mahovsky:
- Handle spaces in the build target name in Visual Studio project files.
From Rob Managan:
- Re-run LaTeX after BibTeX has been re-run in response to a changed
.bib file.
From Joel B. Mohler:
- Make additional TeX auxiliary files (.toc, .idx and .bbl files)
Precious so their removal doesn't affect whether the necessary
sections are included in output PDF or PostScript files.
From Gary Oberbrunner:
- Fix the ability to import modules in the site_scons directory from
a subdirectory.
From Adam Simpkins:
- Make sure parallel (-j) builds all targets even if they show up
multiple times in the child list (as a source and a dependency).
From Matthias Troffaes:
- Don't re-run TeX if the triggering strings (\makeindex, \bibliography
\tableofcontents) are commented out.
From Richard Viney:
- Fix use of custom include and lib paths with Visual Studio 8.
- Select the default .NET Framework SDK Dir based on the version of
Visual Studio being used.
RELEASE 0.96.95 - Mon, 12 Feb 2007 20:25:16 -0600
From Anatoly Techtonik:
- Add the scons.org URL and a package description to the setup.py
arguments.
- Have the Windows installer add a registry entry for scons.bat in the
"App Paths" key, so scons.bat can be executed without adding the
directory to the %PATH%. (Python itself works this way.)
From Anonymous:
- Fix looking for default paths in Visual Studio 8.0 (and later).
- Add -lm to the list of default D libraries for linking.
From Matt Doar:
- Provide a more complete write-your-own-Scanner example in the man page.
From Ralf W. Grosse-Kunstleve:
- Contributed upstream Python change to our copied subprocess.py module
for more efficient standard input processing.
From Steven Knight:
- Fix the Node.FS.Base.rel_path() method when the two nodes are on
different drive letters. (This caused an infinite loop when
trying to write .sconsign files.)
- Fully support Scanners that use a dictionary to map file suffixes
to other scanners.
- Support delayed evaluation of the $SPAWN variable to allow selection
of a function via ${} string expansions.
- Add --srcdir as a synonym for -Y/--repository.
- Document limitations of #include "file.h" with Repository().
- Fix use of a toolpath under the source directory of a BuildDir().
- Fix env.Install() with a file name portion that begins with '#'.
- Fix ParseConfig()'s handling of multiple options in a string that's
replaced a *FLAGS construction variable.
- Have the C++ tools initialize common C compilation variables ($CCFLAGS,
$SHCCFLAGS and $_CCCOMCOM) even if the 'cc' Tool isn't loaded.
From Leanid Nazdrynau:
- Fix detection of Java anonymous classes if a newline precedes the
opening brace.
From Gary Oberbrunner:
- Document use of ${} to execute arbitrary Python code.
- Add support for:
1) automatically adding a site_scons subdirectory (in the top-level
SConstruct directory) to sys.path (PYTHONPATH);
2) automatically importing site_scons/site_init.py;
3) automatically adding site_scons/site_tools to the toolpath.
From John Pye:
- Change ParseConfig() to preserve white space in arguments passed in
as a list.
From a smith:
- Fix adding explicitly-named Java inner class files (and any
other file names that may contain a '$') to Jar files.
From David Vitek:
- Add a NoCache() function to mark targets as unsuitable for propagating
to (or retrieving from) a CacheDir().
From Ben Webb:
- If the swig -noproxy option is used, it won't generate a .py file,
so don't emit it as a target that we expect to be built.
RELEASE 0.96.94 - Sun, 07 Jan 2007 18:36:20 -0600
NOTE: This is a pre-release of 0.97 for testing purposes.
From Anonymous:
- Allow arbitrary white space after a SWIG %module declaration.
From Paul:
- When compiling resources under MinGW, make sure there's a space
between the --include-dir option and its argument.
From Jay Kint:
- Alleviate long command line issues on Windows by executing command
lines directly via os.spawnv() if the command line doesn't need
shell interpretation (has no pipes, redirection, etc.).
From Walter Franzini:
- Exclude additional Debian packaging files from the copyright check.
From Fawad Halim:
- Handle the conflict between the impending Python 2.6 'as' keyword
and our Tool/as.py module name.
From Steven Knight:
- Speed up the Node.FS.Dir.rel_path() method used to generate path names
that get put into the .sconsign* file(s).
- Optimize Node.FS.Base.get_suffix() by computing the suffix once, up
front, when we set the Node's name. (Duh...)
- Reduce the Memoizer's responsibilities to simply counting hits and
misses when the --debug=memoizer option is used, not to actually
handling the key calculation and memoization itself. This speeds
up some configurations significantly, and should cause no functional
differences.
- Add a new scons-time script with subcommands for generating
consistent timing output from SCons configurations, extracting
various information from those timings, and displaying them in
different formats.
- Reduce some unnecessary stat() calls from on-disk entry type checks.
- Fix SideEffect() when used with -j, which was badly broken in 0.96.93.
- Propagate TypeError exceptions when evaluating construction variable
expansions up the stack, so users can see what's going on.
- When disambiguating a Node.FS.Entry into a Dir or File, don't look
in the on-disk source directory until we've confirmed there's no
on-disk entry locally and there *is* one in the srcdir. This avoids
creating a phantom Node that can interfere with dependencies on
directory contents.
- Add an AllowSubstExceptions() function that gives the SConscript
files control over what exceptions cause a string to expand to ''
vs. terminating processing with an error.
- Allow the f90.py and f95.py Tool modules to compile earlier source
source files of earlier Fortran version.
- Fix storing signatures of files retrieved from CacheDir() so they're
correctly identified as up-to-date next invocation.
- Make sure lists of computed source suffixes cached by Builder objects
don't persist across changes to the list of source Builders (so the
addition of suffixes like .ui by the qt.py Tool module take effect).
- Enhance the bootstrap.py script to allow it to be used to execute
SCons more easily from a checked-out source tree.
From Ben Leslie:
- Fix post-Memoizer value caching misspellings in Node.FS._doLookup().
From Rob Managan, Dmitry Mikhin and Joel B. Mohler:
- Handle TeX/LaTeX files in subdirectories by changing directory
before invoking TeX/LaTeX.
- Scan LaTeX files for \bibliography lines.
- Support multiple file names in a "\bibliography{file1,file2}" string.
- Handle TeX warnings about undefined citations.
- Support re-running LaTeX if necessary due to a Table of Contents.
From Dmitry Mikhin:
- Return LaTeX if "Rerun to get citations correct" shows up on the next
line after the "Warning:" string.
From Gary Oberbrunner:
- Add #include lines to fix portability issues in two tests.
- Eliminate some unnecessary os.path.normpath() calls.
- Add a $CFLAGS variable for C-specific options, leaving $CCFLAGS
for options common to C and C++.
From Tom Parker:
- Have the error message print the missing file that Qt can't find.
From John Pye:
- Fix env.MergeFlags() appending to construction variable value of None.
From Steve Robbins:
- Fix the "sconsign" script when the .sconsign.dblite file is explicitly
specified on the command line (and not intuited from the old way of
calling it with just ".sconsign").
From Jose Pablo Ezequiel "Pupeno" Fernandez Silva:
- Give the 'lex' tool knowledge of the additional target files produced
by the flex "--header-file=" and "--tables-file=" options.
- Give the 'yacc' tool knowledge of the additional target files produced
by the bison "-g", "--defines=" and "--graph=" options.
- Generate intermediate files with Objective C file suffixes (.m) when
the lex and yacc source files have appropriate suffixes (.lm and .ym).
From Sohail Somain:
- Have the mslink.py Tool only look for a 'link' executable on Windows
systems.
From Vaclav Smilauer:
- Add support for a "srcdir" keyword argument when calling a Builder,
which will add a srcdir prefix to all non-relative string sources.
From Jonathan Ultis:
- Allow Options converters to take the construction environment as
an optional argument.
RELEASE 0.96.93 - Mon, 06 Nov 2006 00:44:11 -0600
NOTE: This is a pre-release of 0.97 for testing purposes.
From Anonymous:
- Allow Python Value Nodes to be Builder targets.
From Matthias:
- Only filter Visual Studio common filename prefixes on complete
directory names.
From Chad Austin:
- Fix the build of the SCons documentation on systems that don't
have "python" in the $PATH.
From Ken Boortz:
- Enhance ParseConfig() to recognize options that begin with '+'.
From John Calcote, Elliot Murphy:
- Document ways to override the CCPDBFLAGS variable to use the
Microsoft linker's /Zi option instead of the default /Z7.
From Christopher Drexler:
- Make SCons aware bibtex must be called if any \include files
cause creation of a bibliography.
- Make SCons aware that "\bilbiography" in TeX source files means
that related .bbl and .blg bibliography files will be created.
(NOTE: This still needs to search for the string in \include files.)
From David Gruener:
- Fix inconsistent handling of Action strfunction arguments.
- Preserve white space in display Action strfunction strings.
From James Y. Knight and Gerard Patel:
- Support creation of shared object files from assembly language.
From Steven Knight:
- Speed up the Taskmaster significantly by avoiding unnecessary
re-scans of Nodes to find out if there's work to be done, having it
track the currently-executed top-level target directly and not
through its presence on the target list, and eliminating some other
minor list(s), method(s) and manipulation.
- Fix the expansion of $TARGET and $SOURCE in the expansion of
$INSTALLSTR displayed for non-environment calls to InstallAs().
- Fix the ability to have an Alias() call refer to a directory
name that's not identified as a directory until later.
- Enhance runtest.py with an option to use QMTest as the harness.
This will become the default behavior as we add more functionality
to the QMTest side.
- Let linking on mingw use the default function that chooses $CC (gcc)
or $CXX (g++) depending on whether there are any C++ source files.
- Work around a bug in early versions of the Python 2.4 profile module
that caused the --profile= option to fail.
- Only call Options validators and converters once when initializing a
construction environment.
- Fix the ability of env.Append() and env.Prepend(), in all known Python
versions, to handle different input value types when the construction
variable being updated is a dictionary.
- Add a --cache-debug option for information about what files it's
looking for in a CacheDir().
- Document the difference in construction variable expansion between
{Action,Builder}() and env.{Action,Builder}().
- Change the name of env.Copy() to env.Clone(), keeping the old name
around for backwards compatibility (with the intention of eventually
phasing it out to avoid confusion with the Copy() Action factory).
From Arve Knudsen:
- Support cleaning and scanning SWIG-generated files.
From Carsten Koch:
- Allow selection of Visual Studio version by setting $MSVS_VERSION
after construction environment initialization.
From Jean-Baptiste Lab:
- Try using zipimport if we can't import Tool or Platform modules
using the normal "imp" module. This allows SCons to be packaged
using py2exe's all-in-one-zip-file approach.
From Ben Liblit:
- Do not re-scan files if the scanner returns no implicit dependencies.
From Sanjoy Mahajan:
- Change use of $SOURCES to $SOURCE in all TeX-related Tool modules.
From Joel B. Mohler:
- Make SCons aware that "\makeindex" in TeX source files means that
related .ilg, .ind and .idx index files will be created.
(NOTE: This still needs to search for the string in \include files.)
- Prevent scanning the TeX .aux file for additional files from
trying to remove it twice when the -c option is used.
From Leanid Nazdrynau:
- Give the MSVC RES (resource) Builder a src_builder list and a .rc
src_suffix so other builders can generate .rc files.
From Matthew A. Nicholson:
- Enhance Install() and InstallAs() to handle directory trees as sources.
From Jan Nijtmans:
- Don't use the -fPIC flag when using gcc on Windows (e.g. MinGW).
From Greg Noel:
- Add an env.ParseFlags() method that provides separate logic for
parsing GNU tool chain flags into a dictionary.
- Add an env.MergeFlags() method to apply an arbitrary dictionary
of flags to a construction environment's variables.
From Gary Oberbrunner:
- Fix parsing tripartite Intel C compiler version numbers on Linux.
- Extend the ParseConfig() function to recognize -arch and
-isysroot options.
- Have the error message list the known suffixes when a Builder call
can't build a source file with an unknown suffix.
From Karol Pietrzak:
- Avoid recursive calls to main() in the program snippet used by the
SConf subsystem to test linking against libraries. This changes the
default behavior of CheckLib() and CheckLibWithHeader() to print
"Checking for C library foo..." instead of "Checking for main()
in C library foo...".
From John Pye:
- Throw an exception if a command called by ParseConfig() or
ParseFlags() returns an error.
From Stefan Seefeld:
- Initial infrastructure for running SCons tests under QMTest.
From Sohail Somani:
- Fix tests that fail due to gcc warnings.
From Dobes Vandermeer:
- In stack traces, print the full paths of SConscript files.
From Atul Varma:
- Fix detection of Visual C++ Express Edition.
From Dobes Vandermeer:
- Let the src_dir option to the SConscript() function affect all the
the source file paths, instead of treating all source files paths
as relative to the SConscript directory itself.
From Nicolas Vigier:
- Fix finding Fortran modules in build directories.
- Fix use of BuildDir() when the source file in the source directory
is a symlink with a relative path.
From Edward Wang:
- Fix the Memoizer when the SCons Python modules are executed from
.pyo files at different locations from where they were compiled.
From Johan Zander:
- Fix missing os.path.join() when constructing the $FRAMEWORKSDKDIR/bin.
RELEASE 0.96.92 - Mon, 10 Apr 2006 21:08:22 -0400
NOTE: This was a pre-release of 0.97 for testing purposes.
From Anonymous:
- Fix the intelc.py Tool module to not throw an exception if the
only installed version is something other than ia32.
- Set $CCVERSION when using gcc.
From Matthias:
- Support generating project and solution files for Microsoft
Visual Studio version 8.
- Support generating more than one project file for a Microsoft
Visual Studio solution file.
- Add support for a support "runfile" parameter to Microsoft
Visual Studio project file creation.
- Put the project GUID, not the solution GUID, in the right spot
in the solution file.
From Erling Andersen:
- Fix interpretation of Node.FS objects wrapped in Proxy instances,
allowing expansion of things like ${File(TARGET)} in command lines.
From Stanislav Baranov:
- Add a separate MSVSSolution() Builder, with support for the
following new construction variables: $MSVSBUILDCOM, $MSVSCLEANCOM,
$MSVSENCODING, $MSVSREBUILDCOM, $MSVSSCONS, $MSVSSCONSCOM,
$MSVSSCONSFLAGS, $MSVSSCONSCRIPT and $MSVSSOLUTIONCOM.
From Ralph W. Grosse-Kunstleve and Patrick Mezard:
- Remove unneceesary (and incorrect) SCons.Util strings on some function
calls in SCons.Util.
From Bob Halley:
- Fix C/C++ compiler selection on AIX to not always use the external $CC
environment variable.
From August Hörandl:
- Add a scanner for \include and \import files, with support for
searching a directory list in $TEXINPUTS (imported from the external
environment).
- Support $MAKEINDEX, $MAKEINDEXCOM, $MAKEINDEXCOMSTR and
$MAKEINDEXFLAGS for generating indices from .idx files.
From Steven Johnson:
- Add a NoClean() Environment method and function to override removal
of targets during a -c clean, including documentation and tests.
From Steven Knight:
- Check for whether files exist on disk by listing the directory
contents, not calling os.path.exists() file by file. This is
somewhat more efficient in general, and may be significantly
more efficient on Windows.
- Minor speedups in the internal is_Dict(), is_List() and is_String()
functions.
- Fix a signature refactoring bug that caused Qt header files to
get re-generated every time.
- Don't fail when writing signatures if the .sconsign.dblite file is
owned by a different user (e.g. root) from a previous run.
- When deleting variables from stacked OverrideEnvironments, don't
throw a KeyError if we were able to delte the variable from any
Environment in the stack.
- Get rid of the last indentation tabs in the SCons source files and
add -tt to the Python invocations in the packaging build and the
tests so they don't creep back in.
- In Visual Studio project files, put quotes around the -C directory
so everything works even if the path has spaces in it.
- The Intel Fortran compiler uses -object:$TARGET, not "-o $TARGET",
when building object files on Windows. Have the the ifort Tool
modify the default command lines appropriately.
- Document the --debug=explain option in the man page. (How did we
miss this?)
- Add a $LATEXRETRIES variable to allow configuration of the number of
times LaTex can be re-called to try to resolve undefined references.
- Change the order of the arguments to Configure.Checklib() to match
the documentation.
- Handle signature calculation properly when the Python function used
for a FunctionAction is an object method.
- On Windows, assume that absolute path names without a drive letter
refer to the drive on which the SConstruct file lives.
- Add /usr/ccs/bin to the end of the the default external execution
PATH on Solaris.
- Add $PKGCHK and $PKGINFO variables for use on Solaris when searching
for the SunPRO C++ compiler. Make the default value for $PKGCHK
be /usr/sbin/pgkchk (since /usr/sbin isn't usually on the external
execution $PATH).
- Fix a man page example of overriding variables when calling
SharedLibrary() to also set the $LIBSUFFIXES variable.
- Add a --taskmastertrace=FILE option to give some insight on how
the taskmaster decides what Node to build next.
- Changed the names of the old $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
$WIN32DLLPREFIX and $WIN32IMPLIBPREFIX construction variables to
new $WINDOWSDEFPREFIX, $WINDOWSDEFSUFFIX, $WINDOWSDLLPREFIX and
$WINDOWSIMPLIBPREFIX construction variables. The old names are now
deprecated, but preserved for backwards compatibility.
- Fix (?) a runtest.py hang on Windows when the --xml option is used.
- Change the message when an error occurs trying to interact with the
file system to report the target(s) in square brackets (as before) and
the actual file or directory that encountered the error afterwards.
From Chen Lee:
- Add x64 support for Microsoft Visual Studio 8.
From Baptiste Lepilleur:
- Support the --debug=memory option on Windows when the Python version
has the win32process and win32api modules.
- Add support for Visual Studio 2005 Pro.
- Fix portability issues in various tests: test/Case.py,
Test/Java/{JAR,JARCHDIR,JARFLAGS,JAVAC,JAVACFLAGS,JAVAH,RMIC}.py,
test/MSVS/vs-{6.0,7.0,7.1,8.0}-exec.py,
test/Repository/{Java,JavaH,RMIC}.py,
test/QT/{generated-ui,installed,up-to-date,warnings}.py,
test/ZIP/ZIP.py.
- Ignore pkgchk errors on Solaris when searching for the C++ compiler.
- Speed up the SCons/EnvironmentTests.py unit tests.
- Add a --verbose= option to runtest.py to print executed commands
and their output at various levels.
From Christian Maaser:
- Add support for Visual Studio Express Editions.
- Add support for Visual Studio 8 *.manifest files, includng
new $WINDOWS_INSERT_MANIFEST, $WINDOWSPROGMANIFESTSUFFIX,
$WINDOWSPROGMANIFESTPREFIX, $WINDOWSPROGMANIFESTSUFFIX,
$WINDOWSSHLIBMANIFESTPREFIX and $WINDOWSSHLIBMANIFESTSUFFIX
construction variables.
From Adam MacBeth:
- Fix detection of additional Java inner classes following use of a
"new" keyword inside an inner class.
From Sanjoy Mahajan:
- Correct TeX-related command lines to just $SOURCE, not $SOURCES
From Patrick Mezard:
- Execute build commands for a command-line target if any of the
files built along with the target is out of date or non-existent,
not just if the command-line target itself is out of date.
- Fix the -n option when used with -c to print all of the targets
that will be removed for a multi-target Builder call.
- If there's no file in the source directory, make sure there isn't
one in the build directory, too, to avoid dangling files left
over from previous runs when a source file is removed.
- Allow AppendUnique() and PrependUnique() to append strings (and
other atomic objects) to lists.
From Joel B. Mohler:
- Extend latex.py, pdflatex.py, pdftex.py and tex.py so that building
from both TeX and LaTeX files uses the same logic to call $BIBTEX
when it's necessary, to call $MAKEINDEX when it's necessary, and to
call $TEX or $LATEX multiple times to handle undefined references.
- Add an emitter to the various TeX builders so that the generated
.aux and .log files also get deleted by the -c option.
From Leanid Nazdrynau:
- Fix the Qt UIC scanner to work with generated .ui files (by using
the FindFile() function instead of checking by-hand for the file).
From Jan Nieuwenhuizen:
- Fix a problem with interpreting quoted argument lists on command lines.
From Greg Noel:
- Add /sw/bin to the default execution PATH on Mac OS X.
From Kian Win Ong:
- When building a .jar file and there is a $JARCHDIR, put the -C
in front of each .class file on the command line.
- Recognize the Java 1.5 enum keyword.
From Asfand Yar Qazi:
- Add /opt/bin to the default execution PATH on all POSIX platforms
(between /usr/local/bin and /bin).
From Jon Rafkind:
- Fix the use of Configure() contexts from nested subsidiary
SConscript files.
From Christoph Schulz:
- Add support for $CONFIGUREDIR and $CONFIGURELOG variables to control
the directory and logs for configuration tests.
- Add support for a $INSTALLSTR variable.
- Add support for $RANLIBCOM and $RANLIBCOMSTR variables (which fixes
a bug when setting $ARCOMSTR).
From Amir Szekely:
- Add use of $CPPDEFINES to $RCCOM (resource file compilation) on MinGW.
From Erick Tryzelaar:
- Fix the error message when trying to report that a given option is
not gettable/settable from an SConscript file.
From Dobes Vandermeer:
- Add support for SCC and other settings in Microsoft Visual
Studio project and solution files: $MSVS_PROJECT_BASE_PATH,
$MSVS_PROJECT_GUID, $MSVS_SCC_AUX_PATH, $MSVS_SCC_LOCAL_PATH,
$MSVS_SCC_PROJECT_NAME, $MSVS_SCC_PROVIDER,
- Add support for using a $SCONS_HOME variable (imported from the
external environment, or settable internally) to put a shortened
SCons execution line in the Visual Studio project file.
From David J. Van Maren:
- Only filter common prefixes from source files names in Visual Studio
project files if the prefix is a complete (sub)directory name.
From Thad Ward:
- If $MSVSVERSIONS is already set, don't overwrite it with
information from the registry.
RELEASE 0.96.91 - Thu, 08 Sep 2005 07:18:23 -0400
NOTE: This was a pre-release of 0.97 for testing purposes.
From Chad Austin:
- Have the environment store the toolpath and re-use it to find Tools
modules during later Copy() or Tool() calls (unless overridden).
- Normalize the directory path names in SConsignFile() database
files so the same signature file can interoperate on Windows and
non-Windows systems.
- Make --debug=stacktrace print a stacktrace when a UserError is thrown.
- Remove an old, erroneous cut-and-paste comment in Scanner/Dir.py.
From Stanislav Baranov:
- Make it possible to support with custom Alias (sub-)classes.
- Allow Builders to take empty source lists when called.
- Allow access to both TARGET and SOURCE in $*PATH expansions.
- Allow SConscript files to modify BUILD_TARGETS.
From Timothee Besset:
- Add support for Objective C/C++ .m and .mm file suffixes (for
Mac OS X).
From Charles Crain
- Fix the PharLap linkloc.py module to use target+source arguments
when calling env.subst().
From Bjorn Eriksson:
- Fix an incorrect Command() keyword argument in the man page.
- Add a $TEMPFILEPREFIX variable to control the prefix or flag used
to pass a long-command-line-execution tempfile to a command.
From Steven Knight:
- Enhanced the SCons setup.py script to install man pages on
UNIX/Linux systems.
- Add support for an Options.FormatOptionHelpText() method that can
be overridden to customize the format of Options help text.
- Add a global name for the Entry class (which had already been
documented).
- Fix re-scanning of generated source files for implicit dependencies
when the -j option is used.
- Fix a dependency problem that caused $LIBS scans to not be added
to all of the targets in a multiple-target builder call, which
could cause out-of-order builds when the -j option is used.
- Store the paths of source files and dependencies in the .sconsign*
file(s) relative to the target's directory, not relative to the
top-level SConstruct directory. This starts to make it possible to
subdivide the dependency tree arbitrarily by putting an SConstruct
file in every directory and using content signatures.
- Add support for $YACCHFILESUFFIX and $YACCHXXFILESUFFIX variables
that accomodate parser generators that write header files to a
different suffix than the hard-coded .hpp when the -d option is used.
- The default behavior is now to store signature information in a
single .sconsign.dblite file in the top-level SConstruct directory.
The old behavior of a separate .sconsign file in each directory can
be specified by calling SConsignFile(None).
- Remove line number byte codes within the signature calculation
of Python function actions, so that changing the location of an
otherwise unmodified Python function doesn't cause rebuilds.
- Fix AddPreAction() and AddPostAction() when an action has more than
one target file: attach the actions to the Executor, not the Node.
- Allow the source directory of a BuildDir / build_dir to be outside
of the top-level SConstruct directory tree.
- Add a --debug=nomemoizer option that disables the Memoizer for clearer
looks at the counts and profiles of the underlying function calls,
not the Memoizer wrappers.
- Print various --debug= stats even if we exit early (e.g. using -h).
- Really only use the cached content signature value if the file
is older than --max-drift, not just if --max-drift is set.
- Remove support for conversion from old (pre 0.96) .sconsign formats.
- Add support for a --diskcheck option to enable or disable various
on-disk checks: that File and Dir nodes match on-disk entries;
whether an RCS file exists for a missing source file; whether an
SCCS file exists for a missing source file.
- Add a --raw argument to the sconsign script, so it can print a
raw representation of each entry's NodeInfo dictionary.
- Add the 'f90' and 'f95' tools to the list of Fortran compilers
searched for by default.
- Add the +Z option by default when compiling shared objects on
HP-UX.
From Chen Lee:
- Handle Visual Studio project and solution files in Unicode.
From Sanjoy Mahajan:
- Fix a bad use of Copy() in an example in the man page, and a
bad regular expression example in the man page and User's Guide.
From Shannon Mann:
- Have the Visual Studio project file(s) echo "Starting SCons" before
executing SCons, mainly to work around a quote-stripping bug in
(some versions of?) the Windows cmd command executor.
From Georg Mischler:
- Remove the space after the -o option when invoking the Borland
BCC compiler; some versions apparently require that the file name
argument be concatenated with the option.
From Leanid Nazdrynau:
- Fix the Java parser's handling of backslashes in strings.
From Greg Noel:
- Add construction variables to support frameworks on Mac OS X:
$FRAMEWORKS, $FRAMEWORKPREFIX, $FRAMEWORKPATH, $FRAMEWORKPATHPREFIX.
- Re-order link lines so the -o option always comes right after the
command name.
From Gary Oberbrunner:
- Add support for Intel C++ beta 9.0 (both 32 and 64 bit versions).
- Document the new $FRAMEWORK* variables for Mac OS X.
From Karol Pietrzak:
- Add $RPATH (-R) support to the Sun linker Tool (sunlink).
- Add a description of env.subst() to the man page.
From Chris Prince:
- Look in the right directory, not always the local directory, for a
same-named file or directory conflict on disk.
- On Windows, preserve the external environment's %SYSTEMDRIVE%
variable, too.
From Craig Scott:
- Have the Fortran module emitter look for Fortan modules to be created
relative to $FORTRANMODDIR, not the top-level directory.
- When saving Options to a file, run default values through the
converter before comparing them with the set values. This correctly
suppresses Boolean Option values from getting written to the saved
file when they're one of the many synonyms for a default True or
False value.
- Fix the Fortran Scanner's ability to handle a module being used
in the same file in which it is defined.
From Steve-o:
- Add the -KPIC option by default when compiling shared objects on
Solaris.
- Change the default suffix for Solaris objects to .o, to conform to
Sun WorkShop's expectations. Change the profix to so_ so they can
still be differentiated from static objects in the same directory.
From Amir Szekely:
- When calling the resource compiler on MinGW, add --include-dir and
the source directory so it finds the source file.
- Update EnsureSConsVersion() to support revision numbers.
From Greg Ward:
- Fix a misplaced line in the man page.
RELEASE 0.96.90 - Tue, 15 Feb 2005 21:21:12 +0000
NOTE: This was a pre-release of 0.97 for testing purposes.
From Anonymous:
- Fix Java parsing to avoid erroneously identifying a new array
of class instances as an anonymous inner class.
- Fix a typo in the man page description of PathIsDirCreate.
From Chad Austin:
- Allow Help() to be called multiple times, appending to the help
text each call.
- Allow Tools found on a toolpath to import Python modules from
their local directory.
From Steve Christensen:
- Handle exceptions from Python functions as build actions.
- Add a set of canned PathOption validators: PathExists (the default),
PathIsFile, PathIsDir and PathIsDirCreate.
From Matthew Doar:
- Add support for .lex and .yacc file suffixes for Lex and Yacc files.
From Eric Frias:
- Huge performance improvement: wrap the tuples representing an
include path in an object, so that the time it takes to hash the
path doesn't grow porportionally to the length of the path.
From Gottfried Ganssauge:
- Fix SCons on SuSE/AMD-64 Linux by having the wrapper script also
check for the build engine in the parent directory of the Python
library directory (/usr/lib64 instead of /usr/lib).
From Stephen Kennedy:
- Speed up writing the .sconsign file at the end of a run by only
calling sync() once at the end, not after every entry.
From Steven Knight:
- When compiling with Microsoft Visual Studio, don't include the ATL and
MFC directories in the default INCLUDE and LIB environment variables.
- Remove the following deprecated features: the ParseConfig()
global function (deprecated in 0.93); the misspelled "validater"
keyword to the Options.Add() method (deprecated in 0.91); the
SetBuildSignatureType(), SetContentSignatureType(), SetJobs() and
GetJobs() global functions (deprecated in 0.14).
- Fix problems with corrupting the .sconsign.dblite file when
interrupting builds by writing to a temporary file and renaming,
not writing the file directly.
- Fix a 0.96 regression where when running with -k, targets built from
walking dependencies later on the command line would not realize
that a dependency had failed an earlier build attempt, and would
try to rebuild the dependent targets.
- Change the final messages when using -k and errors occur from
"{building,cleaning} terminated because of errors" to "done
{building,cleaning} targets (errors occurred during {build,clean})."
- Allow Configure.CheckFunc() to take an optional header argument
(already supported by Conftest.py) to specify text at the top of
the compiled test file.
- Fix the --debug=explain output when a Python function action changed
so it prints a meaningful string, not the binary representation of
the function contents.
- Allow a ListOption's default value(s) to be a Python list of specified
values, not just a string containing a comma-separated list of names.
- Add a ParseDepends() function that will parse up a list of explicit
dependencies from a "make depend" style file.
- Support the ability to change directory when executing an Action
through "chdir" keyword arguments to Action and Builder creation
and calls.
- Fix handling of Action ojects (and other callables that don't match
our calling arguments) in construction variable expansions.
- On Win32, install scons.bat in the Python directory when installing
from setup.py. (The bdist_wininst installer was already doing this.)
- Fix env.SConscript() when called with a list of SConscipt files.
(The SConscript() global function already worked properly.)
- Add a missing newline to the end of the --debug=explain "unknown
reasons" message.
- Enhance ParseConfig() to work properly for spaces in between the -I,
-L and -l options and their arguments.
- Packaging build fix: Rebuild the files that are use to report the
--version of SCons whenever the development version number changes.
- Fix the ability to specify a target_factory of Dir() to a Builder,
which the default create-a-directory Builder was interfering with.
- Mark a directory as built if it's created as part of the preparation
for another target, to avoid trying to build it again when it comes
up in the target list.
- Allow a function with the right calling signature to be put directly
in an Environment's BUILDERS dictionary, making for easier creation
and use of wrappers (pseudo-Builders) that call other Builders.
- On Python 2.x, wrap lists of Nodes returned by Builders in a UserList
object that adds a method that makes str() object return a string
with all of the Nodes expanded to their path names. (Builders under
Python 1.5.2 still return lists to avoid TypeErrors when trying
to extend() list, so Python 1.5.2 doesn't get pretty-printing of Node
lists, but everything should still function.)
- Allow Aliases to have actions that will be executed whenever
any of the expanded Alias targets are out of date.
- Fix expansion of env.Command() overrides within target and
source file names.
- Support easier customization of what's displayed by various default
actions by adding lots of new construction variables: $ARCOMSTR,
$ASCOMSTR, $ASPPCOMSTR, $BIBTEXCOMSTR, $BITKEEPERCOMSTR, $CCCOMSTR,
$CVSCOMSTR, $CXXCOMSTR, $DCOMSTR, $DVIPDFCOMSTR, $F77COMSTR,
$F90COMSTR, $F95COMSTR, $FORTRANCOMSTR, $GSCOMSTR, $JARCOMSTR,
$JAVACCOMSTR, $JAVAHCOMSTR, $LATEXCOMSTR, $LEXCOMSTR, $LINKCOMSTR,
$M4COMSTR, $MIDLCOMSTR, $P4COMSTR, $PCHCOMSTR, $PDFLATEXCOMSTR,
$PDFTEXCOMSTR, $PSCOMSTR, $QT_MOCFROMCXXCOMSTR, $QT_MOCFROMHCOMSTR,
$QT_UICCOMSTR, $RCCOMSTR, $REGSVRCOMSTR, $RCS_COCOMSTR, $RMICCOMSTR,
$SCCSCOMSTR, $SHCCCOMSTR, $SHCXXCOMSTR, $SHF77COMSTR, $SHF90COMSTR,
$SHF95COMSTR, $SHFORTRANCOMSTR, $SHLINKCOMSTR, $SWIGCOMSTR,
$TARCOMSTR, $TEXCOMSTR, $YACCCOMSTR and $ZIPCOMSTR.
- Add an optional "map" keyword argument to ListOption() that takes a
dictionary to map user-specified values to legal values from the list
(like EnumOption() already doee).
- Add specific exceptions to try:-except: blocks without any listed,
so that they won't catch and mask keyboard interrupts.
- Make --debug={tree,dtree,stree} print something even when there's
a build failure.
- Fix how Scanners sort the found dependencies so that it doesn't
matter whether the dependency file is in a Repository or not.
This may cause recompilations upon upgrade to this version.
- Make AlwaysBuild() work with Alias and Python value Nodes (making
it much simpler to support aliases like "clean" that just invoke
an arbitrary action).
- Have env.ParseConfig() use AppendUnique() by default to suppress
duplicate entries from multiple calls. Add a "unique" keyword
argument to allow the old behavior to be specified.
- Allow the library modules imported by an SConscript file to get at
all of the normally-available global functions and variables by saying
"from SCons.Script import *".
- Add a --debug=memoizer option to print Memoizer hit/mass statistics.
- Allow more than one --debug= option to be set at a time.
- Change --debug=count to report object counts before and after
reading SConscript files and before and after building targets.
- Change --debug=memory output to line up the numbers and to better
match (more or less) the headers on the --debug=count columns.
- Speed things up when there are lists of targets and/or sources by
getting rid of some N^2 walks of the lists involved.
- Cache evaluation of LazyActions so we don't create a new object
for each invocation.
- When scanning, don't create Nodes for include files that don't
actually exist on disk.
- Make supported global variables CScanner, DScanner, ProgramScanner and
SourceFileScanner. Make SourceFileScanner.add_scanner() a supported
part of the public interface. Keep the old SCons.Defaults.*Scan names
around for a while longer since some people were already using them.
- By default, don't scan directories for on-disk files. Add a
DirScanner global scanner that can be used in Builders or Command()
calls that want source directory trees scanned for on-disk changes.
Have the Tar() and Zip() Builders use the new DirScanner to preserve
the behavior of rebuilding a .tar or .zip file if any file or
directory under a source tree changes. Add Command() support for
a source_scanner keyword argument to Command() that can be set to
DirScanner to get this behavior.
- Documentation changes: Explain that $CXXFLAGS contains $CCFLAGS
by default. Fix a bad target_factory example in the man page.
Add appendices to the User's Guide to cover the available Tools,
Builders and construction variables. Comment out the build of
the old Python 10 paper, which doesn't build on all systems and
is old enough at this point that it probably isn't worth the
effort to make it do so.
From Wayne Lee:
- Avoid "maximum recursion limit" errors when removing $(-$) pairs
from long command lines.
From Clive Levinson:
- Make ParseConfig() recognize and add -mno-cygwin to $LINKFLAGS and
$CCFLAGS, and -mwindows to $LINKFLAGS.
From Michael McCracken:
- Add a new "applelink" tool to handle the things like Frameworks and
bundles that Apple has added to gcc for linking.
- Use more appropriate default search lists of linkers, compilers and
and other tools for the 'darwin' platform.
- Add a LoadableModule Builder that builds a bundle on Mac OS X (Darwin)
and a shared library on other systems.
- Improve SWIG tests for use on Mac OS X (Darwin).
From Elliot Murphy:
- Enhance the tests to guarantee persistence of ListOption
values in saved options files.
- Supply the help text when -h is used with the -u, -U or -D options.
From Christian Neeb:
- Fix the Java parser's handling of string definitions to avoid ignoring
subsequent code.
From Han-Wen Nienhuys:
- Optimize variable expansion by: using the re.sub() method (when
possible); not using "eval" for variables for which we can fetch the
value directory; avoiding slowing substitution logic when there's no
'$' in the string.
From Gary Oberbrunner:
- Add an Environment.Dump() method to print the contents of a
construction environment.
- Allow $LIBS (and similar variables) to contain explicit File Nodes.
- Change ParseConfig to add the found library names directly to the
$LIBS variable, instead of returning them.
- Add ParseConfig() support for the -framework GNU linker option.
- Add a PRINT_CMD_LINE_FUNC construction variable to allow people
to filter (or log) command-line output.
- Print an internal Python stack trace in response to an otherwise
unexplained error when --debug=stacktrace is specified.
- Add a --debug=findlibs option to print what's happening when
the scanner is searching for libraries.
- Allow Tool specifications to be passed a dictionary of keyword
arguments.
- Support an Options default value of None, in which case the variable
will not be added to the construction environment unless it's set
explicitly by the user or from an Options file.
- Avoid copying __builtin__ values into a construction environment's
dictionary when evaluating construction variables.
- Add a new cross-platform intelc.py Tool that can detect and
configure the Intel C++ v8 compiler on both Windows, where it's
named icl, and Linux, where it's named icc. It also checks that
the directory specified in the Windows registry exists, and sets a
new $INTEL_C_COMPILER_VERSION construction variable to identify the
version being used. (Niall Douglas contributed an early prototype
of parts of this module.)
- Fix the private Conftest._Have() function so it doesn't change
non-alphanumeric characters to underscores.
- Supply a better error message when a construction variable expansion
has an unknown attribute.
- Documentation changes: Update the man page to describe use of
filenames or Nodes in $LIBS.
From Chris Pawling:
- Have the linkloc tool use $MSVS_VERSION to select the Microsoft
Visual Studio version to use.
From Kevin Quick:
- Fix the Builder name returned from ListBuilders and other instances
of subclasses of the BuilderBase class.
- Add Builders and construction variables to support rpcgen:
RPCGenClient(), RPCGenHeader(), RPCGenService(), RPCGenXDR(),
$RPCGEN, $RPCGENFLAGS, $RPCGENCLIENTFLAGS, $RPCGENHEADERFLAGS,
$RPCGENSERVICEFLAGS, $RPCGENXDRFLAGS.
- Update the man page to document that prefix and suffix Builder
keyword arguments can be strings, callables or dictionaries.
- Provide more info in the error message when a user tries to build
a target multiple ways.
- Fix Delete() when a file doesn't exist and must_exist=1. (We were
unintentionally dependent on a bug in versions of the Python shutil.py
module prior to Python 2.3, which would generate an exception for
a nonexistent file even when ignore_errors was set.)
- Only replace a Node's builder with a non-null source builder.
- Fix a stack trace when a suffix selection dictionary is passed
an empty source file list.
- Allow optional names to be attached to Builders, for default
Builders that don't get attached to construction environments.
- Fix problems with Parallel Task Exception handling.
- Build targets in an associated BuildDir even if there are targets
or subdirectories locally in the source directory.
- If a FunctionAction has a callable class as its underlying Python
function, use its strfunction() method (if any) to display the
action.
- Fix handling when BuildDir() exists but is unwriteable. Add
"Stop." to those error messages for consistency.
- Catch incidents of bad builder creation (without an action) and
supply meaningful error messages.
- Fix handling of src_suffix values that aren't extensions (don't
begin with a '.').
- Don't retrieve files from a CacheDir, but report what would happen,
when the -n option is used.
- Use the source_scanner from the target Node, not the source node
itself.
- Internal Scanners fixes: Make sure Scanners are only passed Nodes.
Fix how a Scanner.Selector called its base class initialization.
Make comparisons of Scanner objects more robust. Add a name to
an internal default ObjSourceScanner.
- Add a deprecated warning for use of the old "scanner" keyword argument
to Builder creation.
- Improve the --debug=explain message when the build action changes.
- Test enhancements in SourceCode.py, option-n.py, midl.py. Better
Command() and Scanner test coverage. Improved test infrastructure
for -c output.
- Refactor the interface between Action and Executor objects to treat
Actions atomically.
- The --debug=presub option will now report the pre-substitution
each action seprately, instead of reporting the entire list before
executing the actions one by one.
- The --debug=explain option explaining a changed action will now
(more correctly) show pre-substitution action strings, instead of
the commands with substituted file names.
- A Node (file) will now be rebuilt if its PreAction or PostAction
actions change.
- Python Function actions now have their calling signature (target,
source, env) reported correctly when displayed.
- Fix BuildDir()/build_dir handling when the build_dir is underneath
the source directory and trying to use entries from the build_dir
as sources for other targets in the build-dir.
- Fix hard-coding of JDK path names in various Java tests.
- Handle Python stack traces consistently (stop at the SConscript stack
frame, by default) even if the Python source code isn't available.
- Improve the performance of the --debug={tree,dtree} options.
- Add --debug=objects logging of creation of OverrideWarner,
EnvironmentCopy and EnvironmentOverride objects.
- Fix command-line expansion of Python Value Nodes.
- Internal cleanups: Remove an unnecessary scan argument. Associate
Scanners only with Builders, not nodes. Apply overrides once when
a Builder is called, not in multiple places. Cache results from the
Node.FS.get_suffix() and Node.get_build_env() methods. Use the Python
md5 modules' hexdigest() method, if there is one. Have Taskmaster
call get_stat() once for each Node and re-use the value instead of
calling it each time it needs the value. Have Node.depends_on()
re-use the list from the children() method instead of calling it
multiple times.
- Use the correct scanner if the same source file is used for targets in
two different environments with the same path but different scanners.
- Collect logic for caching values in memory in a Memoizer class,
which cleans up a lot of special-case code in various methods and
caches additional values to speed up most configurations.
- Add a PathAccept validator to the list of new canned PathOption
validators.
From Jeff Squyres:
- Documentation changes: Use $CPPDEFINES instead of $CCFLAGS in man
page examples.
From Levi Stephen:
- Allow $JARCHDIR to be expanded to other construction variables.
From Christoph Wiedemann:
- Add an Environment.SetDefault() method that only sets values if
they aren't already set.
- Have the qt.py Tool not override variables already set by the user.
- Add separate $QT_BINPATH, $QT_CPPPATH and $QT_LIBPATH variables
so these can be set individually, instead of being hard-wired
relative to $QTDIR.
- The %TEMP% and %TMP% external environment variables are now propagated
automatically to the command execution environment on Windows systems.
- A new --config= command-line option allows explicit control of
of when the Configure() tests are run: --config=force forces all
checks to be run, --config=cache uses all previously cached values,
--config=auto (the default) runs tests only when dependency analysis
determines it's necessary.
- The Configure() subsystem can now write a config.h file with values
like HAVE_STDIO_H, HAVE_LIBM, etc.
- The Configure() subsystem now executes its checks silently when the
-Q option is specified.
- The Configure() subsystem now reports if a test result is being
taken from cache, and prints the standard output and error output
of tests even when cached.
- Configure() test results are now reported as "yes" or "no" instead of
"ok" or "failed."
- Fixed traceback printing when calling the env.Configure() method
instead of the Configure() global function.
- The Configure() subsystem now caches build failures in a .sconsign
file in the subdirectory, not a .cache file. This may cause
tests to be re-executed the first time after you install 0.97.
- Additional significant internal cleanups in the Configure() subsystem
and its tests.
- Have the Qt Builder make uic-generated files dependent on the .ui.h
file, if one exists.
- Add a test to make sure that SCons source code does not contain
try:-except: blocks that catch all errors, which potentially catch
and mask keyboard interrupts.
- Fix us of TargetSignatures('content') with the SConf subsystem.
From Russell Yanofsky:
- Add support for the Metrowerks Codewarrior compiler and linker
(mwcc and mwld).
RELEASE 0.96.1 - Mon, 23 Aug 2004 12:55:50 +0000
From Craig Bachelor:
- Handle white space in the executable Python path name within in MSVS
project files by quoting the path.
- Correct the format of a GUID string in a solution (.dsw) file so
MSVS can correctly "build enable" a project.
From Steven Knight:
- Add a must_exist flag to Delete() to let the user control whether
it's an error if the specified entry doesn't exist. The default
behavior is now to silently do nothing if it doesn't exist.
- Package up the new Platform/darwin.py, mistakenly left out of 0.96.
- Make the scons.bat REM statements into @REM so they aren't printed.
- Make the SCons packaging SConscript files platform independent.
From Anthony Roach:
- Fix scanning of pre-compiled header (.pch) files for #includes,
broken in 0.96.
RELEASE 0.96 - Wed, 18 Aug 2004 13:36:40 +0000
From Chad Austin:
- Make the CacheDir() directory if it doesn't already exist.
- Allow construction variable substitutions in $LIBS specifications.
- Allow the emitter argument to a Builder() to be or expand to a list
of emitter functions, which will be called in sequence.
- Suppress null values in construction variables like $LIBS that use
the internal _concat() function.
- Remove .dll files from the construction variables searched for
libraries that can be fed to Win32 compilers.
From Chad Austin and Christoph Wiedemann:
- Add support for a $RPATH variable to supply a list of directories
to search for shared libraries when linking a program. Used by
the GNU and IRIX linkers (gnulink and sgilink).
From Charles Crain:
- Restore the ability to do construction variable substitutions in all
kinds of *PATH variables, even when the substitution returns a Node
or other object.
From Tom Epperly:
- Allow the Java() Builder to take more than one source directory.
From Ralf W. Grosse-Kunstleve:
- Have SConsignFile() use, by default, a custom "dblite.py" that we can
control and guarantee to work on all Python versions (or nearly so).
From Jonathan Gurley:
- Add support for the newer "ifort" versions of the Intel Fortran
Compiler for Linux.
From Bob Halley:
- Make the new *FLAGS variable type work with copied Environments.
From Chris Hoeppler:
- Initialize the name of a Scanner.Classic scanner correctly.
From James Juhasz:
- Add support for the .dylib shared library suffix and the -dynamiclib
linker option on Mac OS X.
From Steven Knight:
- Add an Execute() method for executing actions directly.
- Support passing environment override keyword arguments to Command().
- Fix use of $MSVS_IGNORE_IDE_PATHS, which was broken when we added
support for $MSVS_USE_MFC_DIRS last release.
- Make env.Append() and env.Prepend() act like the underlying Python
behavior when the variable being appended to is a UserList object.
- Fix a regression that prevented the Command() global function in
0.95 from working with command-line strings as actions.
- Fix checking out a file from a source code management system when
the env.SourceCode() method was called with an individual file name
or node, not a directory name or node.
- Enhance the Task.make_ready() method to create a list of the
out-of-date Nodes for the task for use by the wrapping interface.
- Allow Scanners to pull the list of suffixes from the construction
environment when the "skeys" keyword argument is a string containing
a construction variable to be expanded.
- Support new $CPPSUFFIXES, $DSUFFIXES $FORTRANSUFFIXES, and
$IDLSUFFIXES. construction variables that contain the default list
of suffixes to be scanned by a given type of scanner, allowing these
suffix lists to be easily added to or overridden.
- Speed up Node creation when calling a Builder by comparing whether two
Environments are the same object, not if their underlying dictionaries
are equivalent.
- Add a --debug=explain option that reports the reason(s) why SCons
thinks it must rebuild something.
- Add support for functions that return platform-independent Actions
to Chmod(), Copy(), Delete(), Mkdir(), Move() and Touch() files
and/or directories. Like any other Actions, the returned Action
object may be executed directly using the Execute() global function
or env.Execute() environment method, or may be used as a Builder
action or in an env.Command() action list.
- Add support for the strfunction argument to all types of Actions:
CommandAction, ListAction, and CommandGeneratorAction.
- Speed up turning file system Nodes into strings by caching the
values after we're finished reading the SConscript files.
- Have ParseConfig() recognize and supporting adding the -Wa, -Wl,
and -Wp, flags to ASFLAGS, LINKFLAGS and CPPFLAGS, respectively.
- Change the .sconsign format and the checks for whether a Node is
up-to-date to make dependency checks more efficient and correct.
- Add wrapper Actions to SCons.Defaults for $ASCOM, $ASPPCOM, $LINKCOM,
$SHLINKCOM, $ARCOM, $LEXCOM and $YACCCOM. This makes it possible
to replace the default print behavior with a custom strfunction()
for each of these.
- When a Node has been built, don't walk the whole tree back to delete
the parents's implicit dependencies, let returning up the normal
Taskmaster descent take care of it for us.
- Add documented support for separate target_scanner and source_scanner
arguments to Builder creation, which allows different scanners to
be applied to source files
- Don't re-install or (re-generate) .h files when a subsidiary #included
.h file changes. This eliminates incorrect circular dependencies
with .h files generated from other source files.
- Slim down the internal Sig.Calculator class by eliminating methods
whose functionality is now covered by Node methods.
- Document use of the target_factory and source_factory keyword
arguments when creating Builder objects. Enhance Dir Nodes so that
they can be created with user-specified Builder objects.
- Don't blow up with stack trace when the external $PATH environment
variable isn't set.
- Make Builder calls return lists all the time, even if there's only
one target. This keeps things consistent and easier to program to
across platforms.
- Add a Flatten() function to make it easier to deal with the Builders
all returning lists of targets, not individual targets.
- Performance optimizations in Node.FS.__doLookup().
- Man page fixes: formatting typos, misspellings, bad example.
- User's Guide fixes: Fix the signatures of the various example
*Options() calls. Triple-quote properly a multi-line Split example.
- User's Guide additions: Chapter describing File and Directory
Nodes. Section describing declarative nature of SCons functions in
SConscript files. Better organization and clarification of points
raised by Robert P. J. Day. Chapter describing SConf (Autoconf-like)
functionality. Chapter describing how to install Python and
SCons. Chapter describing Java builds.
From Chris Murray:
- Add a .win32 attribute to force file names to expand with
Windows backslash path separators.
- Fix escaping file names on command lines when the expansion is
concatenated with another string.
- Add support for Fortran 90 and Fortran 95. This adds $FORTRAN*
variables that specify a default compiler, command-line, flags,
etc. for all Fortran versions, plus separate $F90* and $F95*
variables for when different compilers/flags/etc. must be specified
for different Fortran versions.
- Have individual tools that create libraries override the default
$LIBPREFIX and $LIBSUFFIX values set by the platform. This makes
it easier to use Microsoft Visual Studio tools on a CygWin platform.
From Gary Oberbrunner:
- Add a --debug=presub option to print actions prior to substitution.
- Add a warning upon use of the override keywords "targets" and
"sources" when calling Builders. These are usually mistakes which
are otherwise silently (and confusingly) turned into construction
variable overrides.
- Try to find the ICL license file path name in the external environment
and the registry before resorting to the hard-coded path name.
- Add support for fetching command-line keyword=value arguments in
order from an ARGLIST list.
- Avoid stack traces when trying to read dangling symlinks.
- Treat file "extensions" that only contain digits as part of the
file basename. This supports version numbers as part of shared
library names, for example.
- Avoid problems when there are null entries (None or '') in tool
lists or CPPPATH.
- Add an example and explanation of how to use "tools = ['default', ..."
when creating a construction environment.
- Add a section describing File and Directory Nodes and some of their
attributes and methods.
- Have ParseConfig() add a returned -pthread flag to both $CCFLAGS
and $LINKFLAGS.
- Fix some test portability issues on Mac OS X (darwin).
From Simon Perkins:
- Fix a bug introduced in building shared libraries under MinGW.
From Kevin Quick:
- Handling SCons exceptions according to Pythonic standards.
- Fix test/chained-build.py on systems that execute within one second.
- Fix tests on systems where 'ar' warns about archive creation.
From Anthony Roach:
- Fix use of the --implicit-cache option with timestamp signatures.
- If Visual Studio is installed, assume the C/C++ compiler, the linker
and the MIDL compiler that comes with it are available, too.
- Better error messages when evaluating a construction variable
expansion yields a Python syntax error.
- Change the generation of PDB files when using Visual Studio from
compile time to link time.
From sam th:
- Allow SConf.CheckLib() to search a list of libraries, like the
Autoconf AC_SEARCH_LIBS macro.
- Allow the env.WhereIs() method to take a "reject" argument to
let it weed out specific path names.
From Christoph Wiedemann:
- Add new Moc() and Uic() Builders for more explicit control over
Qt builds, plus new construction variables to control them:
$QT_AUTOSCAN, $QT_DEBUG, $QT_MOCCXXPREFIX, $QT_MOCCXXSUFFIX,
$QT_MOCHPREFIX, $QT_MOCHSUFFIX, $QT_UICDECLPREFIX, $QT_UICDECLSUFFIX,
$QT_UICIMPLPREFIX, $QT_UICIMPLSUFFIX and $QT_UISUFFIX.
- Add a new single_source keyword argument for Builders that enforces
a single source file on calls to the Builder.
RELEASE 0.95 - Mon, 08 Mar 2004 06:43:20 -0600
From Chad Austin:
- Replace print statements with calls to sys.stdout.write() so output
lines stay together when -j is used.
- Add portability fixes for a number of tests.
- Accomodate the fact that Cygwin's os.path.normcase() lies about
the underlying system being case-sensitive.
- Fix an incorrect _concat() call in the $RCINCFLAGS definition for
the mingw Tool.
- Fix a problem with the msvc tool with Python versions prior to 2.3.
- Add support for a "toolpath" Tool() and Environment keyword that
allows Tool modules to be found in specified local directories.
- Work around Cygwin Python's silly fiction that it's using a
case-sensitive file system.
- More robust handling of data in VCComponents.dat.
- If the "env" command is available, spawn commands with the more
general "env -" instead of "env -i".
From Kerim Borchaev:
- Fix a typo in a msvc.py's registry lookup: "VCComponents.dat", not
"VSComponents.dat".
From Chris Burghart:
- Fix the ability to save/restore a PackageOption to a file.
From Steve Christensen:
- Update the MSVS .NET and MSVC 6.0/7.0 path detection.
From David M. Cooke:
- Make the Fortran scanner case-insensitive for the INCLUDE string.
From Charles Crain:
- If no version of MSVC is detected but the tool is specified,
use the MSVC 6.0 paths by default.
- Ignore any "6.1" version of MSVC found in the registry; this is a
phony version number (created by later service packs?) and would
throw off the logic if the user had any non-default paths configure.
- Correctly detect if the user has independently configured the MSVC
"include," "lib" or "path" in the registry and use the appropriate
values. Previously, SCons would only use the values if all three
were set in the registry.
- Make sure side-effect nodes are prepare()d before building their
corresponding target.
- Preserve the ability to call BuildDir() multiple times with the
same target and source directory arguments.
From Andy Friesen:
- Add support for the Digital Mars "D" programming language.
From Scott Lystig Fritchie:
- Fix the ability to use a custom _concat() function in the
construction environment when calling _stripixes().
- Make the message about ignoring a missing SConscript file into a
suppressable Warning, not a hard-coded sys.stderr.write().
- If a builder can be called multiple times for a target (because
the sources and overrides are identical, or it's a builder with the
"multi" flag set), allow the builder to be called through multiple
environments so long as the builders have the same signature for
the environments in questions (that is, they're the same action).
From Bob Halley:
- When multiple targets are built by a single action, retrieve all
of them from cache, not just the first target, and exec the build
command if any of the targets isn't present in the cache.
From Zephaniah Hull:
- Fix command-line ARGUMENTS with multiple = in them.
From Steven Knight:
- Fix EnsureSConsVersion() so it checks against the SCons version,
not the Python version, on Pythons with sys.version_info.
- Don't swallow the AttributeError when someone uses an expansion like
$TARGET.bak, so we can supply a more informative error message.
- Fix an odd double-quote escape sequence in the man page.
- Fix looking up a naked drive letter as a directory (Dir('C:')).
- Support using File nodes in the LIBS construction variable.
- Allow the LIBS construction variable to be a single string or File
node, not a list, when only one library is needed.
- Fix typos in the man page: JAVACHDIR => JARCHDIR; add "for_signature"
to the __call__() example in the "Variable Substitution" section.
- Correct error message spellings of "non-existant" to "non-existent."
- When scanning for libraries to link with, don't append $LIBPREFIXES
or $LIBSUFFIXES values to the $LIBS values if they're already present.
- Add a ZIPCOMPRESSION construction variable to control whether the
internal Python action for the Zip Builder compresses the file or
not. The default value is zipfile.ZIP_DEFLATED, which generates
a compressed file.
- Refactor construction variable expansion to support recursive
expansion of variables (e.g. CCFLAGS = "$CCFLAGS -g") without going
into an infinite loop. Support this in all construction variable
overrides, as well as when copying Environments.
- Fix calling Configure() from more than one subsidiary SConscript file.
- Fix the env.Action() method so it returns the correct type of
Action for its argument(s).
- Fix specifying .class files as input to JavaH with the .class suffix
when they weren't generated using the Java Builder.
- Make the check for whether all of the objects going into a
SharedLibrary() are shared work even if the object was built in a
previous run.
- Supply meaningful error messages, not stack traces, if we try to add
a non-Node as a source, dependency, or ignored dependency of a Node.
- Generate MSVS Project files that re-invoke SCons properly regardless
of whether the file was built via scons.bat or scons.py.
(Thanks to Niall Douglas for contributing code and testing.)
- Fix TestCmd.py, runtest.py and specific tests to accomodate being
run from directories whose paths include white space.
- Provide a more useful error message if a construction variable
expansion contains a syntax error during evaluation.
- Fix transparent checkout of implicit dependency files from SCCS
and RCS.
- Added new --debug=count, --debug=memory and --debug=objects options.
--debug=count and --debug=objects only print anything when run
under Python 2.1 or later.
- Deprecate the "overrides" keyword argument to Builder() creation
in favor of using keyword argument values directly (like we do
for builder execution and the like).
- Always use the Builder overrides in substitutions, not just if
there isn't a target-specific environment.
- Add new "rsrcpath" and "rsrcdir" and attributes to $TARGET/$SOURCE,
so Builder command lines can find things in Repository source
directories when using BuildDir.
- Fix the M4 Builder so that it chdirs to the Repository directory
when the input file is in the source directory of a BuildDir.
- Save memory at build time by allowing Nodes to delete their build
environments after they've been built.
- Add AppendUnique() and PrependUnique() Environment methods, which
add values to construction variables like Append() and Prepend()
do, but suppress any duplicate elements in the list.
- Allow the 'qt' tool to still be used successfully from a copied
Environment. The include and library directories previously ended up
having the same string re-appended to the end, yielding an incorrect
path name.
- Supply a more descriptive error message when the source for a target
can't be found.
- Initialize all *FLAGS variables with objects do the right thing with
appending flags as strings or lists.
- Make things like ${TARGET.dir} work in *PATH construction variables.
- Allow a $MSVS_USE_MFC_DIRS construction variable to control whether
ATL and MFC directories are included in the default INCLUDE and
LIB paths.
- Document the dbm_module argument to the SConsignFile() function.
From Vincent Risi:
- Add support for the bcc32, ilink32 and tlib Borland tools.
From Anthony Roach:
- Supply an error message if the user tries to configure a BuildDir
for a directory that already has one.
- Remove documentation of the still-unimplemented -e option.
- Add -H help text listing the legal --debug values.
- Don't choke if a construction variable is a non-string value.
- Build Type Libraries in the target directory, not the source
directory.
- Add an appendix to the User's Guide showing how to accomplish
various common tasks in Python.
From Greg Spencer:
- Add support for Microsoft Visual Studio 2003 (version 7.1).
- Evaluate $MSVSPROJECTSUFFIX and $MSVSSOLUTIONSUFFIX when the Builder
is invoked, not when the tool is initialized.
From Christoph Wiedemann:
- When compiling Qt, make sure the moc_*.cc files are compiled using
the flags from the environment used to specify the target, not
the environment that first has the Qt Builders attached.
RELEASE 0.94 - Fri, 07 Nov 2003 05:29:48 -0600
From Hartmut Goebel:
- Add several new types of canned functions to help create options:
BoolOption(), EnumOption(), ListOption(), PackageOption(),
PathOption().
From Steven Knight:
- Fix use of CPPDEFINES with C++ source files.
- Fix env.Append() when the operand is an object with a __cmp__()
method (like a Scanner instance).
- Fix subclassing the Environment and Scanner classes.
- Add BUILD_TARGETS, COMMAND_LINE_TARGETS and DEFAULT_TARGETS variables.
From Steve Leblanc:
- SGI fixes: Fix C++ compilation, add a separate Tool/sgic++.py module.
From Gary Oberbrunner:
- Fix how the man page un-indents after examples in some browsers.
From Vincent Risi:
- Fix the C and C++ tool specifications for AIX.
RELEASE 0.93 - Thu, 23 Oct 2003 07:26:55 -0500
From J.T. Conklin:
- On POSIX, execute commands with the more modern os.spawnvpe()
function, if it's available.
- Scan .S, .spp and .SPP files for C preprocessor dependencies.
- Refactor the Job.Parallel() class to use a thread pool without a
condition variable. This improves parallel build performance and
handles keyboard interrupts properly when -j is used.
From Charles Crain:
- Add support for a JARCHDIR variable to control changing to a
directory using the jar -C option.
- Add support for detecting Java manifest files when using jar,
and specifying them using the jar m flag.
- Fix some Python 2.2 specific things in various tool modules.
- Support directories as build sources, so that a rebuild of a target
can be triggered if anything underneath the directory changes.
- Have the scons.bat and scons.py files look for the SCons modules
in site-packages as well.
From Christian Engel:
- Support more flexible inclusion of separate C and C++ compilers.
- Use package management tools on AIX and Solaris to find where
the comilers are installed, and what version they are.
- Add support for CCVERSION and CXXVERSION variables for a number
of C and C++ compilers.
From Sergey Fogel:
- Add test cases for the new capabilities to run bibtex and to rerun
latex as needed.
From Ralf W. Grosse-Kunstleve:
- Accomodate anydbm modules that don't have a sync() method.
- Allow SConsignFile() to take an argument specifying the DBM
module to be used.
From Stephen Kennedy:
- Add support for a configurable global .sconsign.dbm file which
can be used to avoid cluttering each directory with an individual
.sconsign file.
From John Johnson:
- Fix (re-)scanning of dependencies in generated or installed
header files.
From Steven Knight:
- The -Q option suppressed too many messages; fix it so that it only
suppresses the Reading/Building messages.
- Support #include when there's no space before the opening quote
or angle bracket.
- Accomodate alphanumeric version strings in EnsurePythonVersion().
- Support arbitrary expansion of construction variables within
file and directory arguments to Builder calls and Environment methods.
- Add Environment-method versions of the following global functions:
Action(), AddPostAction(), AddPreAction(), Alias(), Builder(),
BuildDir(), CacheDir(), Clean(), Configure(), Default(),
EnsurePythonVersion(), EnsureSConsVersion(), Environment(),
Exit(), Export(), FindFile(), GetBuildPath(), GetOption(), Help(),
Import(), Literal(), Local(), Platform(), Repository(), Scanner(),
SConscriptChdir(), SConsignFile(), SetOption(), SourceSignatures(),
Split(), TargetSignatures(), Tool(), Value().
- Add the following global functions that correspond to the same-named
Environment methods: AlwaysBuild(), Command(), Depends(), Ignore(),
Install(), InstallAs(), Precious(), SideEffect() and SourceCode().
- Add the following global functions that correspond to the default
Builder methods supported by SCons: CFile(), CXXFile(), DVI(), Jar(),
Java(), JavaH(), Library(), M4(), MSVSProject(), Object(), PCH(),
PDF(), PostScript(), Program(), RES(), RMIC(), SharedLibrary(),
SharedObject(), StaticLibrary(), StaticObject(), Tar(), TypeLibrary()
and Zip().
- Rearrange the man page to show construction environment methods and
global functions in the same list, and to explain the difference.
- Alphabetize the explanations of the builder methods in the man page.
- Rename the Environment.Environment class to Enviroment.Base.
Allow the wrapping interface to extend an Environment by using its own
subclass of Environment.Base and setting a new Environment.Environment
variable as the calling entry point.
- Deprecate the ParseConfig() global function in favor of a same-named
construction environment method.
- Allow the Environment.WhereIs() method to take explicit path and
pathext arguments (like the underlying SCons.Util.WhereIs() function).
- Remove the long-obsolete {Get,Set}CommandHandler() functions.
- Enhance env.Append() to suppress null values when appropriate.
- Fix ParseConfig() so it works regardless of initial construction
variable values.
Extend CheckHeader(), CheckCHeader(), CheckCXXHeader() and
CheckLibWithHeader() to accept a list of header files that will be
#included in the test. The last one in the list is assumed to be
the one being checked for. (Prototype code contributed by Gerard
Patel and Niall Douglas).
- Supply a warning when -j is used and threading isn't built in to
the current version of Python.
- First release of the User's Guide (finally, and despite a lot
of things still missing from it...).
From Clark McGrew:
- Generalize the action for .tex files so that it will decide whether
a file is TeX or LaTeX, check the .aux output to decide if it should
run bibtex, and check the .log output to re-run LaTeX if needed.
From Bram Moolenaar:
- Split the non-SCons-specific functionality from SConf.py to a new,
re-usable Conftest.py module.
From Gary Oberbrunner:
- Allow a directory to be the target or source or dependency of a
Depends(), Ignore(), Precious() or SideEffect() call.
From Gerard Patel:
- Use the %{_mandir} macro when building our RPM package.
From Marko Rauhamaa:
- Have the closing message say "...terminated because of errors" if
there were any.
From Anthony Roach:
- On Win32 systems, only use "rm" to delete files if Cygwin is being
used. ("rm" doesn't understand Win32-format path names.)
From Christoph Wiedemann:
- Fix test/SWIG.py to find the Python include directory in all cases.
- Fix a bug in detection of Qt installed on the local system.
- Support returning Python 2.3 BooleanType values from Configure checks.
- Provide an error message if someone mistakenly tries to call a
Configure check from within a Builder function.
- Support calling a Builder when a Configure context is still open.
- Handle interrupts better by eliminating all try:-except: blocks
which caught any and all exceptions, including KeyboardInterrupt.
- Add a --duplicate= option to control how files are duplicated.
RELEASE 0.92 - Wed, 20 Aug 2003 03:45:28 -0500
From Charles Crain and Gary Oberbrunner:
- Fix Tool import problems with the Intel and PharLap linkers.
From Steven Knight
- Refactor the DictCmdGenerator class to be a Selector subclass.
- Allow the DefaultEnvironment() function to take arguments and pass
them to instantiation of the default construction environment.
- Update the Debian package so it uses Python 2.2 and more closely
resembles the currently official Debian packaging info.
From Gerard Patel
- When the yacc -d flag is used, take the .h file base name from the
target .c file, not the source (matching what yacc does).
RELEASE 0.91 - Thu, 14 Aug 2003 13:00:44 -0500
From Chad Austin:
- Support specifying a list of tools when calling Environment.Copy().
- Give a Value Nodes a timestamp of the system time when they're
created, so they'll work when using timestamp-based signatures.
- Add a DefaultEnvironment() function that only creates a default
environment on-demand (for fetching source files, e.g.).
- Portability fix for test/M4.py.
From Steven Knight:
- Tighten up the scons -H help output.
- When the input yacc file ends in .yy and the -d flag is specified,
recognize that a .hpp file (not a .h file) will be created.
- Make builder prefixes work correctly when deducing a target
from a source file name in another directory.
- Documentation fixes: typo in the man page; explain up-front about
not propagating the external environment.
- Use "cvs co -d" instead of "cvs co -p >" when checking out something
from CVS with a specified module name. This avoids zero-length
files when there is a checkout error.
- Add an "sconsign" script to print the contents of .sconsign files.
- Speed up maintaining the various lists of Node children by using
dictionaries to avoid "x in list" searches.
- Cache the computed list of Node children minus those being Ignored
so it's only calculated once.

(or using any other arbitrary action) by making sure all Action
instances have strfunction() methods.
- Allow the source of Command() to be a directory.
- Better error handling of things like raw TypeErrors in SConscripts.
- When installing using "setup.py install --prefix=", suppress the
distutils warning message about adding the (incorrect) library
directory to your search path.
- Correct the spelling of the "validater" option to "validator."
Add a DeprecatedWarning when the old spelling is used.
- Allow a Builder's emitter to be a dictionary that maps source file
suffixes to emitter functions, using the suffix of the first file
in the source list to pick the right one.
- Refactor the creation of the Program, *Object and *Library Builders
so that they're moved out of SCons.Defaults and created on demand.
- Don't split SConscript file names on white space.
- Document the SConscript function's "dirs" and "name" keywords.
- Remove the internal (and superfluous) SCons.Util.argmunge() function.
- Add /TP to the default CXXFLAGS for msvc, so it can compile all
of the suffixes we use as C++ files.
- Allow the "prefix" and "suffix" attributes of a Builder to be
callable objects that return generated strings, or dictionaries
that map a source file suffix to the right prefix/suffix.
- Support a MAXLINELINELENGTH construction variable on Win32 systems
to control when a temporary file is used for long command lines.
- Make how we build .rpm packages not depend on the installation
locations from the distutils being used.
- When deducing a target Node, create it directly from the first
source Node, not by trying to create the right string to pass to
arg2nodes().
- Add support for SWIG.
From Bram Moolenaar:
- Test portability fixes for FreeBSD.
From Gary Oberbrunner:

are incorrect.
- Fix the value returned by the Node.prevsiginfo() method to conform
to a previous change when checking whether a node is current.

(also) print the command line that is being executed through the
temporary file.
- Initialize the LIB environment variable when using the Intel
compiler (icl).
- Documentation fixes: better explain the AlwaysBuild() function.
From Laurent Pelecq:
- When the -debug=pdb option is specified, use pdb.Pdb().runcall() to
call pdb directly, don't call Python recursively.

From Christoph Wiedemann:
- Have the g++ Tool actually use g++ in preference to c++.

linking with any C++ objects.
- Avoid SCons hanging when a piped command has a lot of output to read.
- Add QT support for preprocessing .ui files into .c files.

- Save Options string values that contain a single quote correctly.
- Save any Options values that are changed from the default
Environment values, not just ones changed on the command line or in
an Options file.
- Make closing the Options file descriptor exception-safe.
From Steven Knight:
- SCons now enforces (with an error) that construction variables
must have the same form as valid Python identifiers.
- Fix man page bugs: remove duplicate AddPostAction() description;
document no_import_lib; mention that CPPFLAGS does not contain
$_CPPINCFLAGS; mention that F77FLAGS does not contain $_F77INCFLAGS;
mention that LINKFLAGS and SHLINKFLAGS contains neither $_LIBFLAGS
nor $_LIBDIRFLAGS.
- Eliminate a dependency on the distutils.fancy_getopt module by
copying and pasting its wrap_text() function directly.

- Refactor command-line interpolation and signature calculation
so we can use real Node attributes.
From Steven Knight:
- Add Java support (javac, javah, jar and rmic).
- Propagate the external SYSTEMROOT environment variable into ENV on
Win32 systems, so external commands that use sockets will work.
- Add a .posix attribute to PathList expansions.
- Check out CVS source files using POSIX path names (forward slashes
as separators) even on Win32.
- Add Node.clear() and Node.FS.Entry.clear() methods to wipe out a
Node's state, allowing it to be re-evaluated by continuous
integration build interfaces.

to {Target,Source}Signatures(). Deprecate the old names but support
them for backwards compatibility.
- Add internal SCons.Node.FS.{Dir,File}.Entry() methods.

external PATH instead of what SCons would use.
- Fix the interaction of SideEffect() and BuildDir() so that (for
example) PDB files get put correctly in a BuildDir().

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

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

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

argument from Builder definition (reported by Gary Ruben).
- Support using env.Append() on BUILDERS (and other dictionaries).
(Bug reported by Bj=F6rn Bylander.)
- Setting the BUILDERS construction variable now properly clears
the previous Builder attributes from the construction Environment.
(Bug reported by Bj=F6rn Bylander.)
- Fix adding a prefix to a file when the target isn't specified.
(Bug reported by Esa Ilari Vuokko.)
- Clean up error messages from problems duplicating into read-only
BuildDir directories or into read-only files.
- Add a CommandAction.strfunction() method, and add an "env" argument
to the FunctionAction.strfunction() method, so that all Action
objects have strfunction() methods, and the functions for building
and returning a string both take the same arguments.
- Add support for new CacheDir() functionality to share derived files
between builds, with related options --cache-disable, --cache-force,
and --cache-show.
- Change the default behavior when no targets are specified to build
everything in the current directory and below (like Make). This
can be disabled by specifying Default(None) in an SConscript.
- Revamp SCons installation to fix a case-sensitive installation
on Win32 systems, and to add SCons-specific --standard-lib,
--standalone-lib, and --version-lib options for easier user
control of where the libraries get installed.
- Fix the ability to directly import and use Platform and Tool modules
that have been implicitly imported into an Environment().
- Add support for allowing an embedding interface to annotate a node
when it's created.
- Extend the SConscript() function to accept build_dir and duplicate
keyword arguments that function like a BuildDir() call.
From Steve Leblanc:
- Fix the output of -c -n when directories are involved, so it
matches -c.
From Anthony Roach:
- Use a different shared object suffix (.os) when using gcc so shared
and static objects can exist side-by-side in the same directory.
- Allow the same object files on Win32 to be linked into either
shared or static libraries.
- Cache implicit cache values when using --implicit-cache.
RELEASE 0.10 - Thu, 16 Jan 2003 04:11:46 -0600
From Derrick 'dman' Hudson:
- Support Repositories on other file systems by symlinking or
copying files when hard linking won't work.
From Steven Knight:
- Remove Python bytecode (*.pyc) files from the scons-local packages.
- Have FunctionActions print a description of what they're doing
(a representation of the Python call).
- Fix the Install() method so that, like other actions, it prints
what would have happened when the -n option is used.
- Don't create duplicate source files in a BuildDir when the -n
option is used.
- Refactor the Scanner interface to eliminate unnecessary Scanner
calls and make it easier to write efficient scanners.
- Added a "recursive" flag to Scanner creation that specifies the
Scanner should be invoked recursively on dependency files returned
by the scanner.
- Significant performance improvement from using a more efficient
check, throughout the code, for whether a Node has a Builder.
- Fix specifying only the source file to MultiStepBuilders such as
the Program Builder. (Bug reported by Dean Bair.)
- Fix an exception when building from a file with the same basename as
the subdirectory in which it lives. (Bug reported by Gerard Patel.)
- Fix automatic deduction of a target file name when there are
multiple source files specified; the target is now deduced from just
the first source file in the list.
- Documentation fixes: better initial explanation of SConscript files;
fix a misformatted "table" in the StaticObject explanation.
From Steven Knight and Steve Leblanc:
- Fix the -c option so it will remove symlinks.
From Steve Leblanc:
- Add a Clean() method to support removing user-specified targets
when using the -c option.
- Add a development script for running SCons through PyChecker.

number of default jobs (still overridden by -j).
- Convert the .sconsign file format from ASCII to a pickled Python
data structure.
- Error message cleanups: Made consistent the format of error
messages (now all start with "scons: ***") and warning messages (now
all start with "scons: warning:"). Caught more cases with the "Do
not know how to build" error message.
- Added support for the MinGW tool chain.
- Added a --debug=includes option.
RELEASE 0.09 - Thu, 5 Dec 2002 04:48:25 -0600

archiver), too.
From Charles Crain:
- Allow $$ in a string to be passed through as $.
- Support file names with odd characters in them.
- Add support for construction variable substition on scanner
directories (in CPPPATH, F77PATH, LIBPATH, etc.).
From Charles Crain and Steven Knight:
- Add Repository() functionality, including the -Y option.
From Steven Knight:
- Fix auto-deduction of target names so that deduced targets end
up in the same subdirectory as the source.
- Don't remove source files specified on the command line!
- Suport the Intel Fortran Compiler (ifl.exe).
- Supply an error message if there are no command-line or
Default() targets specified.
- Fix the ASPPCOM values for the GNU assembler.
(Bug reported by Brett Polivka.)
- Fix an exception thrown when a Default() directory was specified
when using the -U option.
- Issue a warning when -c can't remove a target.
- Eliminate unnecessary Scanner calls by checking for the
existence of a file before scanning it. (This adds a generic
hook to check an arbitrary condition before scanning.)
- Add explicit messages to tell when we're "Reading SConscript files
...," "done reading SConscript files," "Building targets," and
"done building targets." Add a -Q option to supress these.
- Add separate $SHOBJPREFIX and $SHOBJSUFFIX construction variables
(by default, the same as $OBJPREFIX and $OBJSUFFIX).
- Add Make-like error messages when asked to build a source file,
and before trying to build a file that doesn't have all its source
files (including when an invalid drive letter is used on WIN32).
- Add an scons-local-{version} package (in both .tar.gz and .zip
flavors) to help people who want to ship SCons as a stand-alone
build tool in their software packages.
- Prevent SCons from unlinking files in certain situations when
the -n option is used.
- Change the name of Tool/lib.py to Tool/mslib.py.
From Steven Knight and Anthony Roach:
- Man page: document the fact that Builder calls return Node objects.
From Steve LeBlanc:
- Refactor option processing to use our own version of Greg Ward's
Optik module, modified to run under Python 1.5.2.
- Add a ParseConfig() command to modify an environment based on
parsing output from a *-config command.
From Jeff Petkau:
- Fix interpretation of '#/../foo' on Win32 systems.
From Anthony Roach:
- Fixed use of command lines with spaces in their arguments,
and use of Nodes with spaces in their string representation.
- Make access and modification times of files in a BuildDir match
the source file, even when hard linking isn't available.
- Make -U be case insensitive on Win32 systems.
- Issue a warning and continue when finding a corrupt .sconsign file.
- Fix using an alias as a dependency of a target so that if one of the
alias' dependencies gets rebuilt, the resulting target will, too.
- Fix differently ordered targets causing unnecessary rebuilds
on case insensitive systems.
- Use os.system() to execute external commands whenever the "env"
utility is available, which is much faster than fork()/exec(),
and fixes the -j option on several platforms.
- Fix use of -j with multiple targets.
- Add an Options() object for friendlier accomodation of command-
line arguments.
- Add support for Microsoft VC++ precompiled header (.pch) files,
debugger (.pdb) files, and resource (.rc) files.
- Don't compute the $_CPPINCFLAGS, $_F77INCFLAGS, $_LIBFLAGS and
$_LIBDIRFLAGS variables each time a command is executed, define
them so they're computed only as needed. Add a new _concat
function to the Environment that allows people to define their
own similar variables.
- Fix dependency scans when $LIBS is overridden.

- Fix the overly-verbose stack trace on ListBuilder build errors.
- Add a SetContentSignatureType() function, allowing use of file
timestamps instead of MD5 signatures.

the starting directory, in addition to a Dir object.
- Allow the command handler to be selected via the SPAWN, SHELL
and ESCAPE construction variables.
- Allow construction variables to be overridden when a Builder
is called.
From sam th:
- Dynamically check for the existence of utilities with which to
initialize Environments by default.
RELEASE 0.08 - Mon, 15 Jul 2002 12:08:51 -0500
From Charles Crain:
- Fixed a bug with relative CPPPATH dirs when using BuildDir().
(Bug reported by Bob Summerwill.)
- Added a warnings framework and a --warn option to enable or
disable warnings.
- Make the C scanner warn users if files referenced by #include
directives cannot be found and --warn=dependency is specified.
- The BUILDERS construction variable should now be a dictionary
that maps builder names to actions. Existing uses of lists,
and the Builder name= keyword argument, generate warnings
about use of deprecated features.
- Removed the "shared" keyword argument from the Object and
Library builders.
- Added separated StaticObject, SharedObject, StaticLibrary and
SharedLibrary builders. Made Object and Library synonyms for
StaticObject and StaticLibrary, respectively.
- Add LIBS and LIBPATH dependencies for shared libraries.
- Removed support for the prefix, suffix and src_suffix arguments
to Builder() to be callable functions.
- Fix handling file names with multiple dots.
- Allow a build directory to be outside of the SConstruct tree.
- Add a FindFile() function that searches for a file node with a
specified name.
- Add $CPPFLAGS to the shared-object command lines for g++ and gcc.
From Charles Crain and Steven Knight:
- Add a "tools=" keyword argument to Environment instantiation,
and a separate Tools() method, for more flexible specification
of tool-specific environment changes.
From Steven Knight:
- Add a "platform=" keyword argument to Environment instantiation,
and a separate Platform() method, for more flexible specification
of platform-specific environment changes.
- Updated README instructions and setup.py code to catch an
installation failure from not having distutils installed.
- Add descriptions to the -H help text for -D, -u and -U so
people can tell them apart.
- Remove the old feature of automatically splitting strings
of file names on white space.
- Add a dependency Scanner for native Fortran "include" statements,
using a new "F77PATH" construction variable.
- Fix C #include scanning to detect file names with characters like
'-' in them.
- Add more specific version / build output to the -v option.
- Add support for the GNU as, Microsoft masm, and nasm assemblers.
- Allow the "target" argument to a Builder call to be omitted, in
which case the target(s) are deduced from the source file(s) and the
Builder's specified suffix.
- Add a tar archive builder.
- Add preliminary support for the OS/2 Platform, including the icc
and ilink Tools.
From Jeff Petkau:
- Fix --implicit-cache if the scanner returns an empty list.
From Anthony Roach:
- Add a "multi" keyword argument to Builder creation that specifies
it's okay to call the builder multiple times for a target.
- Set a "multi" on Aliases so multiple calls will append to an Alias.
- Fix emitter functions' use of path names when using BuildDir or
in subdirectories.
- Fix --implicit-cache causing redundant rebuilds when the header
file list changed.
- Fix --implicit-cache when a file has no implicit dependencies and
its source is generated.
- Make the drive letters on Windows always be the same case, so that
changes in the case of drive letters don't cause a rebuild.
- Fall back to importing the SCons.TimeStamp module if the SCons.MD5
module can't be imported.
- Fix interrupt handling to guarantee that a single interrupt will
halt SCons both when using -j and not.
- Fix .sconsign signature storage so that output files of one build
can be safely used as input files to another build.
- Added a --debug=time option to print SCons execution times.
- Print an error message if a file can't be unlinked before being
built, rather than just silently terminating the build.
- Add a SideEffect() method that can be used to tell the build
engine that a given file is created as a side effect of building
a target. A file can be specified as a side effect of more than
one build comand, in which case the commands will not be executed
simultaneously.
- Significant performance gains from not using our own version of
the inefficient stock os.path.splitext() method, caching source
suffix computation, code cleanup in MultiStepBuilder.__call__(),
and replicating some logic in scons_subst().
- Add --implicit-deps-changed and --implicit-deps-unchanged options.
- Add a GetLaunchDir() function.
- Add a SetBuildSignatureType() function.
From Zed Shaw:
- Add an Append() method to Environments, to append values to
construction variables.
- Change the name of Update() to Replace(). Keep Update() as a
deprecated synonym, at least for now.
From Terrel Shumway:
- Use a $PYTHON construction variable, initialized to sys.executable,
when using Python to build parts of the SCons packages.
- Use sys.prefix, not sys.exec_prefix, to find pdb.py.
RELEASE 0.07 - Thu, 2 May 2002 13:37:16 -0500
From Chad Austin:
- Changes to build SCons packages on IRIX (and other *NIces).
- Don't create a directory Node when a file already exists there,
and vice versa.
- Add 'dirs' and 'names' keyword arguments to SConscript for
easier specification of subsidiary SConscript files.
From Charles Crain:
- Internal cleanup of environment passing to function Actions.
- Builders can now take arbitrary keyword arguments to create
attributes to be passed to: command generator functions,
FunctionAction functions, Builder emitter functions (below),
and prefix/suffix generator functions (below).
- Command generator functions can now return ANYTHING that can be
converted into an Action (a function, a string, a CommandGenerator
instance, even an ActionBase instance).
- Actions now call get_contents() with the actual target and source
nodes used for the build.
- A new DictCmdGenerator class replaces CompositeBuilder to support
more flexible Builder behavior internally.
- Builders can now take an emitter= keyword argument. An emitter
is a function that takes target, source, and env argument, then
return a 2-tuple of (new sources, new targets). The emitter is
called when the Builder is __call__'ed, allowing a user to modify
source and target lists.
- The prefix, suffix and src_suffix Builder arguments now take a
callable as well a string. The callable is passed the Environment
and any extra Builder keyword arguments and is expected to return
the appropriate prefix or suffix.
- CommandActions can now be a string, a list of command + argument
strings, or a list of commands (strings or lists).
- Added shared library support. The Object and Library Builders now
take a "shared=1" keyword argument to specify that a shared object
or shared library should be built. It is an error to try to build
static objects into a shared library or vice versa.
- Win32 support for .def files has been added. Added the Win32-specific
construction variables $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
$WIN32DLLPREFIX and $WIN32IMPLIBPREFIX. When building a .dll,
the new construction variable $WIN32_INSERT_DEF, controls whether
the appropriately-named .def file is inserted into the target
list (if not already present). A .lib file is always added to
a Library build if not present in the list of targets.
- ListBuilder now passes all targets to the action, not just the first.
- Fix so that -c now deletes generated yacc .h files.
- Builder actions and emitter functions can now be initialized, through
construction variables, to things other than strings.
- Make top-relative '#/dir' lookups work like '#dir'.
- Fix for relative CPPPATH directories in subsidiary SConscript files
(broken in 0.06).
- Add a for_signature argument to command generators, so that
generators that need to can return distinct values for the
command signature and for executing the command.
From Alex Jacques:
- Create a better scons.bat file from a py2bat.py script on the Python
mailing list two years ago (modeled after pl2bat.pl).
From Steven Knight:
- Fix so that -c -n does *not* remove the targets!
- Man page: Add a hierarchical libraries + Program example.
- Support long MSVC linker command lines through a builder action
that writes to a temporary file and uses the magic MSVC "link @file"
argument syntax if the line is longer than 2K characters.
- Fix F77 command-line options on Win32 (use /Fo instead of -o).
- Use the same action to build from .c (lower case) and .C (upper
case) files on case-insensitive systems like Win32.
- Support building a PDF file directly from a TeX or LaTeX file
using pdftex or pdflatex.
- Add a -x option to runtest.py to specify the script being tested.
A -X option indicates it's an executable, not a script to feed
to the Python interpreter.
- Add a Split() function (identical to SCons.Util.argmunge()) for use
in the next release, when Builders will no longer automatically split
strings on white space.
From Steve Leblanc:
- Add the SConscriptChdir() method.
From Anthony Roach:
- Fix --debug=tree when used with directory targets.
- Significant internal restructuring of Scanners and Taskmaster.
- Added new --debug=dtree option.
- Fixes for --profile option.
- Performance improvement in construction variable substitution.
- Implemented caching of content signatures, plus added --max-drift
option to control caching.
- Implemented caching of dependency signatures, enabled by new
--implicit-cache option.
- Added abspath construction variable modifier.
- Added $SOURCE variable as a synonym for $SOURCES[0].
- Write out .sconsign files on error or interrupt so intermediate
build results are saved.
- Change the -U option to -D. Make a new -U that builds just the
targets from the local SConscript file.
- Fixed use of sys.path so Python modules can be imported from
the SConscript directory.
- Fix for using Aliases with the -u, -U and -D options.
- Fix so that Nodes can be passed to SConscript files.
From Moshe Zadka:
- Changes for official Debian packaging.
RELEASE 0.06 - Thu, 28 Mar 2002 01:24:29 -0600
From Charles Crain:
- Fix command generators to expand construction variables.
- Make FunctionAction arguments be Nodes, not strings.
From Stephen Kennedy:
- Performance: Use a dictionary, not a list, for a Node's parents.
From Steven Knight:
- Add .zip files to the packages we build.
- Man page: document LIBS, fix a typo, document ARGUMENTS.
- Added RANLIB and RANLIBFLAGS construction variables. Only use them
in ARCOM if there's a "ranlib" program on the system.
- Add a configurable CFILESUFFIX for the Builder of .l and .y files
into C files.
- Add a CXXFile Builder that turns .ll and .yy files into .cc files
(configurable via a CXXFILESUFFIX construction variable).
- Use the POSIX-standard lex -t flag, not the GNU-specific -o flag.
(Bug reported by Russell Christensen.)
- Fixed an exception when CPPPATH or LIBPATH is a null string.
(Bug reported by Richard Kiss.)
- Add a --profile=FILE option to make profiling SCons easier.
- Modify the new DVI builder to create .dvi files from LaTeX (.ltx
and .latex) files.
- Add support for Aliases (phony targets).

suffixes (a la GNU Make): .f, .F, .for, .FOR, .fpp and .FPP
- Support a CPPFLAGS variable on all default commands that use the
C preprocessor.
From Steve Leblanc:
- Add support for the -U option.
- Allow CPPPATH, LIBPATH and LIBS to be specified as white-space
separated strings.
- Add a document builder to create .dvi files from TeX (.tex) files.
From Anthony Roach:
- Fix: Construction variables with values of 0 were incorrectly
interpolated as ''.
- Support env['VAR'] to fetch construction variable values.
- Man page: document Precious().
RELEASE 0.05 - Thu, 21 Feb 2002 16:50:03 -0600
From Chad Austin:
- Set PROGSUFFIX to .exe under Cygwin.
From Charles Crain:
- Allow a library to specified as a command-line source file, not just
in the LIBS construction variable.
- Compensate for a bug in os.path.normpath() that returns '' for './'
on WIN32.
- More performance optimizations: cache #include lines from files,
eliminate unnecessary calls.
- If a prefix or suffix contains white space, treat the resulting
concatenation as separate arguments.
- Fix irregularities in the way we fetch DevStudio information from
the Windows registry, and in our registry error handling.
From Steven Knight:
- Flush stdout after print so it intermixes correctly with stderr
when redirected.
- Allow Scanners to return a list of strings, and document how to
write your own Scanners.
- Look up implicit (scanned) dependencies relative to the directory
of file being scanned.
- Make writing .sconsign files more robust by first trying to write
to a temp file that gets renamed.
- Create all of the directories for a list of targets before trying
to build any of the targets.
- WIN32 portability fixes in tests.
- Allow the list of variables exported to an SConscript file to be
a UserList, too.
- Document the overlooked LIBPATH construction variable.
(Bug reported by Eicke Godehardt.)
- Fix so that Ignore() ignores indirect, implicit dependencies
(included files), not just direct dependencies.
- Put the man page in the Debian distribution.
- Run HTML docs through tidy to clean up the HTML (for Konqueror).
- Add preliminary support for Unicode strings.
- Efficiency: don't scan dependencies more than once during the
walk of a tree.
- Fix the -c option so it doesn't stop removing targets if one doesn't
already exist.
(Bug reported by Paul Connell.)
- Fix the --debug=pdb option when run on Windows NT.
(Bug reported by Paul Connell.)
- Add support for the -q option.
From Steve Leblanc:
- Add support for the -u option.
- Add .cc and .hh file suffixes to the C Scanner.
From Anthony Roach:
- Make the scons script return an error code on failures.
- Add support for using code to generate a command to build a target.
RELEASE 0.04 - Wed, 30 Jan 2002 11:09:42 -0600
From Charles Crain:
- Significant performance improvements in the Node.FS and
Scanner subsystems.
- Fix signatures of binary files on Win32 systems.
- Allow LIBS and LIBPATH to be strings, not just arrays.
- Print a traceback if a Python-function builder throws an exception.
From Steven Knight:
- Fix using a directory as a Default(), and allow Default() to
support white space in file names for strings in arrays.
- Man page updates: corrected some mistakes, documented various
missing Environment methods, alphabetized the construction
variables and other functions, defined begin and end macros for
the example sections, regularized white space separation, fixed
the use of Export() in the Multiple Variants example.
- Function action fixes: None is now a successful return value.
Exceptions are now reported. Document function actions.
- Add 'Action' and 'Scanner' to the global keywords so SConscript
files can use them too.
- Removed the Wrapper class between Nodes and Walkers.
- Add examples using Library, LIBS, and LIBPATH.
- The C Scanner now always returns a sorted list of dependencies
so order changes don't cause unnecessary rebuilds.
- Strip $(-$) bracketed text from command lines. Use this to
surround $_INCDIRS and $_LIBDIRS so we don't rebuild in response
to changes to -I or -L options.
- Add the Ignore() method to ignore dependencies.
- Provide an error message when a nonexistent target is specified
on the command line.
- Remove targets before building them, and add an Environment
Precious() method to override that.
- Eliminate redundant calls to the same builder when the target is a
list of targets: Add a ListBuilder class that wraps Builders to
handle lists atomically. Extend the Task class to support building
and updating multiple targets in a single Task. Simplify the
interface between Task and Taskmaster.
- Add a --debug=pdb option to re-run SCons under the Python debugger.
- Only compute a build signature once for each node.
- Changes to our sys.path[] manipulation to support installation into
an arbitrary --prefix value.
From Steve Leblanc:
- Add var=value command-line arguments.
RELEASE 0.03 - Fri, 11 Jan 2002 01:09:30 -0600
From Charles Crain:
- Performance improvements in the Node.FS and Sig.Calculator classes.
- Add the InstallAs() method.
- Execute commands through an external interpreter (sh, cmd.exe, or
command.com) to handle redirection metacharacters.
- Allow the user to supply a command handler.
From Steven Knight:
- Search both /usr/lib and /usr/local/lib for scons directories by
adding them both to sys.path, with whichever is in sys.prefix first.
- Fix interpreting strings of multiple white-space separated file names
as separate file names, allowing prefixes and suffixes to be appended
to each individually.
- Refactor to move CompositeBuilder initialization logic from the
factory wrapper to the __init__() method, and allow a Builder to
have both an action and a src_builder (or array of them).
- Refactor BuilderBase.__call__() to separate Node creation/lookup
from initialization of the Node's builder information.
- Add a CFile Builder object that supports turning lex (.l) and
yacc (.y) files into .c files.
- Document: variable interpretation attributes; how to propogate
the user's environment variables to executed commands; how to
build variants in multiple BuildDirs.
- Collect String, Dict, and List type-checking in common utility
routines so we can accept User{String,Dict,List}s all over.
- Put the Action factory and classes into their own module.
- Use one CPlusPlusAction in the Object Builder's action dictionary,
instead of letting it create multiple identical instances.
- Document the Install() and InstallAs() methods.
From Steve Leblanc:
- Require that a Builder be given a name argument, supplying a
useful error message when it isn't.
From Anthony Roach:
- Add a "duplicate" keyword argument to BuildDir() that can be set
to prevent linking/copying source files into build directories.
- Add a "--debug=tree" option to print an ASCII dependency tree.
- Fetch the location of the Microsoft Visual C++ compiler(s) from
the Registry, instead of hard-coding the location.
- Made Scanner objects take Nodes, not path names.
- Have the C Scanner cache the #include file names instead of
(re-)scanning the file each time it's called.
- Created a separate class for parent "nodes" of file system roots,
eliminating the need for separate is-parent-null checks everywhere.
- Removed defined __hash__() and __cmp() methods from FS.Entry, in
favor of Python's more efficient built-in identity comparisons.
RELEASE 0.02 - Sun, 23 Dec 2001 19:05:09 -0600
From Charles Crain:
- Added the Install(), BuildDir(), and Export() methods.
- Fix the -C option by delaying setting the top of the FS tree.
- Avoid putting the directory path on the libraries in the LIBS
construction variable.
- Added a GetBuildPath() method to return the full path to the
Node for a specified string.
- Fixed variable substitution in CPPPATH and LIBPATH.
From Steven Knight:
- Fixed the version comment in the scons.bat (the UNIX geek used
# instead of @rem).
- Fix to setup.py so it doesn't require a sys.argv[1] argument.
- Provide make-like warning message for "command not found" and
similar errors.
- Added an EXAMPLES section to the man page.
- Make Default() targets properly relative to their SConscript
file's subdirectory.
From Anthony Roach:
- Documented CXXFLAGS, CXXCOM, and CPPPATH.
- Fixed SCONS_LIB_DIR to work as documented.
- Made Default() accept Nodes as arguments.
