[Scons-dev] Question about SCons CSIG behavior

[William Blevins]

Team,

I noticed something peculiar when examining how CSIG's are generated for
Nodes.  In the case that get_content returns an error (IE. file is
missing), then the signature becomes MD5( '' ).

This seems a bit counter-intuitive.  Would it make more sense for
get_csig() to return None until the node can actually be evaluated because
otherwise a missing file has the same signature as an empty file, and those
are two very different things.

V/R,
William
