[Scons-users] Failed command does not invalidate the target

[Tom Tanner (BLOOMBERG/ LONDON)]

I'm all for this. It makes a lot of sense.

Note however that if scons gets terminated with extreme prejudice, this won't work properly, which people should be aware of.

SCons does assume that you don’t modify the output files from a build.
It only keeps the signatures for sources, not targets.


This is true.  However I'm wondering about Neil's original question, which is shouldn't SCons delete the target if the builder fails?  I thought SCons always deletes the target(s) before running a builder, so I'm guessing in his case the builder wrote a partial output file and then failed.  I think in this case it probably does make sense for SCons to delete the failed output file.  Opinions?
