Bug #28838 for as: Memory Leak

Tue Aug 14 17:32:59 2007 hooo [...] cpan.org - Ticket created

Subject:

Memory Leak

There is a memory leak in 'as'. Unloading as does not remove the module entry in the hash table used in 'as'. Cheers Ho

I have noticed that 'as' is the same as Package::Alias or is there a difference?

Why are you using a top level namespace?

Please provide me with code to illustrate what you mean with "Unloading as". Liz

This difference is in the way you specify the namespace aliases: the basic functionality is the same. Liz

Why not? Seems to me that something like this should belong in the core. So why not start with a pragma? Liz

I beg your pardon, there is no memory leak. I tested it with: package main; use as; eval " use Tie::Scalar as => TieScalar$_; use TieScalar$_ as => TieScalarXXX$_; no TieScalar$_; no TieScalarXXX$_; " foreach 1..1000000000; __END__ Looking in the documentation, 'as' is designed to use in the package where the 'use' statement occures, to directly renaming a module name while importing. In difference to 'Package::Alias' which can be used in the package itself so the package can provide an alias. Thought i could write: package Very::Long::Package::Name; use as 'Bah'; This would be easier to read than: package Very::Long::Package::Name; use Package::Alias 'Bah' => __PACKAGE__; What do you think about this syntax? Cheers Ho.
