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. + + - 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. + + - 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.
