devel::leak

Leak(3) 						User Contributed Perl Documentation						   Leak(3)

NAME

       Devel::Leak - Utility for looking for perl objects that are not reclaimed.

SYNOPSIS

	 use Devel::Leak;
	 ... setup code

	 my $count = Devel::Leak::NoteSV($handle);

	 ... code that may leak

	 Devel::Leak::CheckSV($handle);

DESCRIPTION

       Devel::Leak has two functions "NoteSV" and "CheckSV".

       "NoteSV" walks the perl internal table of allocated SVs (scalar values) - (which actually  contains arrays and hashes too), and records
       their addresses in a table. It returns a count of these "things", and stores a pointer to the table (which is obtained from the heap using
       malloc()) in its argument.

       "CheckSV" is passed argument which holds a pointer to a table created by "NoteSV". It re-walks the perl-internals and calls sv_dump() for
       any "things" which did not exist when "NoteSV" was called. It returns a count of the number of "things" now allocated.

CAVEATS

       Note that you need a perl built with -DDEBUGGING for sv_dump() to print anything, but counts are valid in any perl.

       If new "things" have been created, "CheckSV" may (also) report additional "things" which are allocated by the sv_dump() code.

HISTORY

       This little utility module was part of Tk until the variable renaming in perl5.005 made it clear that Tk had no business knowing this much
       about the perl internals.
