| Subject: | Doesn't work with version 1.9102 of CPAN [+fix] |
I get the following error:

Refusing to autoload 'expand' 'Module' 'SetDualVar' in recursion
Refusing to autoload 'expand' 'Module' 'CPAN::MyConfig' in recursion

BEGIN failed--compilation aborted at test_autoinc.pl line 2.
The problem seems to be that CPAN uses the AUTOLOAD subrountine to
re-direct unscoped calls (such as the expand call by Module::AutoINC) to
CPAN::Shell. In the change from CPAN-1.8802 to CPAN-1.88_73 protection
was added to avoid recursion in AUTOLOAD. What happens is that each
time expand is called, CPAN fails to load CPAN::MyConfig and SetDualVar
and hence Module::AutoINC gets invoked again causing the recursion in
the CPAN::AUTOLOAD subroutine.
A fix that works for me is to scope the call to expand. I.e.
< foreach my $m (expand('Module', $module)) {
Show quoted text
> foreach my $m (CPAN::Shell->expand('Module', $module)) {
This should be compatible with earlier versions of CPAN from what I can
see of the code in other versions. However, I've not tested it except
for version 1.9102.
