Re: Split cons code (was: Re: Debian package and development of CONS)

Thank you for that clarification.  That is not the problem I solved.  I had very little experience with Cons prior to 2.3.0, as one of my first assignments was to upgrade our initial prototype of using Cons to 2.3.0.  We do have the problem that you identify, and it is a problem in that many developers use DevStudio to build, but our official build is Cons and they must use that.  I knew, and have informed them that outside contamination by other build systems requires a clean build in the Cons environment.  But, I didn't make a big deal of this because Make, and I'm sure DevStudio would have the same problem.

I apologize for leading you astray as to having a fix,

Are we really talking about the same thing ?

Does your patched version work better than like below ? (I tried to
apply your patch, but couldn't notice any difference in this
situation).

Suppose you have a Construct file like:

        $e = cons->new();
        $e->Command("tgt.txt", "src.txt", "cp %<  %>");

And issue the following commands:

        $ echo "qwerty" > src.txt
        $ cons .
        cp src.txt tgt.txt
        $ cp /dev/null tgt.txt
        $ cons .
        cons.pl: "." is up-to-date.    <----- should NOT be up-to-date


Note that this is just a "as small as possible" example. As far as I
know it is not specific to "Command", but a general problem in 2.3.0
an later (even with your patch).

I would be glad to be proven wrong ...
