[Slashcode-development] Problems in inheritance tree

[Alessio B. <al...@al...>]

I'm patching Slash 2.0pre3 for PostgreSQL. I've reworked heavily
Slash::DB::PostregSQL, but I didn't touch the @ISA scheme. And I've got
a problem in this.

I've managed to have slashd working fine, fixing
Slash::DB::Static::PostgreSQL. But every web request ends up in
something like 

[Tue May  8 15:48:09 2001] [error] Can't locate object method
"sqlConnect" via package "Slash::DB" at
/usr/local/lib/site_perl/i386-linux/Slash/Apache/User.pm line 75.

sqlConnect is in fact located in Slash::DB::Utility, 
@Slash::DB::ISA = qw[ Slash::Utility ] but at runtime it (should) get 
@Slash::DB::ISAPg     = qw[ Slash::Utility Slash::DB::PostgreSQL
Slash::DB::MySQL ];
and 
@Slash::DB::PostgreSQL::ISA = qw(Slash::DB::Utility)

it's not simple at all and I get confused... But what I understand is
that sqlConnect should be called from Slash::DB -> Slash::DB::PostgreSQL
-> Slash::DB::Utility . This doesn't happen. 

Any idea :-?

I am using a test environment of Apache 1.3.19 and mod_perl 1.25 (perl
5.005_03) on Debian potato, connecting to a PostgreSQL 7.1.1 database on
Digital Unix.
