[bug] various operations create (incorrect) PMCProxy objects in HLL namespaces

[pmichaud]

I'm opening this ticket from the thread starting at  http://lists.parrot.org/pipermail/parrot-dev/2009-May/002297.html . Essentially, there are a variety of operations that can cause PMCProxy objects to be incorrectly generated in HLL namespaces.

Here's an example:

$ ./parrot --version
This is Parrot version 1.2.0-devel built for i386-linux.
Copyright (C) 2001-2009, Parrot Foundation.

$ cat x.pir
.HLL 'foo'

.sub 'main' :main
    $P0 = new 'Class'
    $I0 = isa $P0, 'Sub'

    $P1 = get_root_global ['foo'], 'Sub'
    say $P1
.end

$ ./parrot x.pir
Sub
$ 

Clearly an entry for 'Sub' should not be made in the foo? HLL namespace.

This behavior did not exist in 1.0.0 (which means we need to correct it prior to 1.4 release).

$ ./parrot --version
This is Parrot version 1.0.0-devel built for i386-linux.

$ cat x.pir
.HLL 'foo'

.sub 'main' :main
    $P0 = new 'Class'
    $I0 = isa $P0, 'Sub'

    $P1 = get_root_global ['foo'], 'Sub'
    say $P1
.end

$ ./parrot x.pir
Null PMC in say
current instr.: 'main' pc 11 (x.pir:8)
$ 

I suspect that ultimately the bug is that Parrot_oo_get_class and Parrot_oo_get_class_str are creating PMCProxy objects in namespaces they have no business creating things in.

IIUC, partcl is currently blocking on this ticket.

The patch NotFound pasted at:  http://nopaste.snit.ch/16698 resolves the issue exposed by partcl's [namespace children] test.

Applied a cleaned version of the patch in r39220.

Added the example as a test in t/oo/proxy.t on r39222
