Bug #1200

Package exported function: wrong package name

Description

Very strange.
The code in Interpreter.C look reasonable, but this message is wrong:

--> ERROR: Cannot export the name "Gens_Ker_Hom_Mod" because the same name was already exported by package $experimental

The original package exporting the function is ModuleHom.
The package I'm loading (trying to export the function again) is called experimental.

I am postponing this because it is not so important/urgent, and looks like it might be quick tricky to solve :-/

#4 Updated by John Abbott over 3 years ago

The relevant line appears to be Interpreter.C:4289.

Here is a test input which triggers the bug:

package $first;
export john;
define john(x)  return x+1; enddefine; 
endpackage;

package $second;
export john;
define john(x)  return x+1; enddefine;
endpackage;

UPDATE this example seems to work... huh?!?

Is this even a bug?
In my installation the symbol Gens_Ker_Mod_Hom is indeed exported by a package called experimental.cpkg5.

Why do we have a package called experimental.cpjkg5? Is it distributed in the release?

Anyway, who reported this issue???

Can we close it?

These are various functions with temporary/experimental interface, but are (likely) currently used by some package (or user).

Anyway, who reported this issue???

I guess it was me, forgetting to be logged in as Admin

Yes: it works correctly, and I see no log in Interpreter.C mentioning a fix. I wonder if I got confused when I worte it.
