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.
