Namespace nightmare

[Fernando-61]

Hi all,

I've been spending some hours finding out why a class wasn't found in
a quite complex project, and after a lot of try-and-errors, I managed
to reduce the problem to three really simple files.

-- A.StartupClass.boo ------------

namespace A

import A.N1
import A.N2

class StartupClass:

  def Method():

    v1 = MyClass()
    v2 = MyOtherClass()
  end

end

-- A.N1.MyClass.boo ------------

namespace A.N1

class MyClass:

end

-- A.N2.MyOtherClass.boo ------------

namespace A.N2

class MyOtherClass:

end

------------------------------------

The compiler says:

C:\>booc -wsa "A.StartupClass.boo" "A.N1.MyClass.boo"
"A.N2.MyOtherClass.boo"
Boo Compiler version 0.9.2.3383 (CLR 2.0.50727.3082)
A.StartupClass.boo(1,1): BCW0008: WARNING: Duplicate namespace:
'A.N2'.
1 warning(s).
A.StartupClass.boo(1,1): BCE0005: Unknown identifier: 'MyOtherClass'.
1 error(s).

If I change the order of the imports in A.StartupClass.boo, then I
get:

C:\>booc -wsa "A.StartupClass.boo" "A.N1.MyClass.boo"
"A.N2.MyOtherClass.boo"
Boo Compiler version 0.9.2.3383 (CLR 2.0.50727.3082)
A.StartupClass.boo(1,1): BCW0008: WARNING: Duplicate namespace:
'A.N1'.
1 warning(s).
A.StartupClass.boo(1,1): BCE0005: Unknown identifier: 'MyClass'.
1 error(s).

---------------------------

I do not understand the warnings, and of course I do not agree with
the errors.
I must be missing something obvious, but I really cannot see what it
is...

Without imports, or even only with one import, it works - but it's not
what I want to do!

-- A.StartupClass.boo (modified, it works) ------------

namespace A

import A.N1

class StartupClass:

  def Method():

    v1 = MyClass()
    v2 = A.N2.MyOtherClass()
  end

end

------------------------------------

Any ideas? Is this a known issue? Should I report it somewhere else?

Thanks in advance,

Fernando Nájera

Nice catch!
This is indeed looks like a bug.
Please open an issue about this in the bug tracker ( http://jira.codehaus.org/browse/BOO )

Hmm, actually it is a regression bug, it works on 0.9, I've not bisected yet but I assume it's been silently introduced (we have no testcase for that) during the TypeSystem refactoring.

On my way.

I will enter that comment in the bug tracker too.

Thanks a lot,

Done. http://jira.codehaus.org/browse/BOO-1256

I hope I entered it properly... if not, let me know and I'll change
whatever it's needed.
