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: + + -

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: + + -

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). + + -

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.

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.

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.
